Raw Blame History

1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
This change adds the ability to use `unread-char' multiple times
without interspersed reads and adds the new procedure
`unread-string'. The change is optimized for the common case of
unreading a single character. This is also the reason behind the
choice to store characters in the port itself: in most cases no
extra malloc is required.
The amount of code in some macros in ports.h has been increased to
the extent that they would fit better as C functions, but, since
this code belongs to the port representation, such functions
should be placed in ports.c which would cause calls back and forth
between ports.c and genio.c. That is not good for performance.
Also, keeping them as macros allows the compiler to do some
optimizations which are needed to make the current interface
(SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
One benchmark (Guile startup time) indicates an increase of
loading speed of 1%. Another (reading (using `read') boot-9.scm
10 times) shows no change in performance.
(Caveat: Since Gary is redesigning I/O anyway, no big efforts were
made to find a beautiful solution.)
* ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
(SCM_TRY_CLRDY): New macro: Only clear the first unread
character. (SCM_CLRDY clears all.)
(SCM_N_READY_CHARS): New macro: Returns number of unread
characters in a port. Returns wrong answer if SCM_CRDYP is false.
(struct scm_port_table): New fields: `entry' contains port table
index, `cp' points to last unread char, `cbuf' is the buffer for
unread chars, `cbufend' points after end of the character buffer.
* ports.h, ports.c (scm_unread_string): New procedure.
(scm_grow_port_cbuf): New function.
* ports.c (scm_add_to_port_table, scm_remove_from_port_table):
Handle new fields.
(scm_generic_fgets), fports.c (local_fgets): Use a loop
to read unread characters. Use SCM_TRY_CLRDY instead of
SCM_CLRDY.
* ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
* genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
* genio.c, genio.h (scm_ungets): New function.
* genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
sections.
1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
declarations. (Thanks to Russ McManus.)
1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
* numbers.c (num2long): As a software archeologist, I'm proud of
this finding! :) Preliminary dating suggests an almost 4 year old
remnant from the SCM ancestor. The sample has been removed from
the finding site and is now safely stored in the repository.
* numbers.h: Removed prototype for num2long.
* unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
* gh_data.c (gh_scm2doubles): Make it possible to pass result
array as second arg.
(gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
* gh.h: Updated and added prototypes.
* gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
* gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
* guile-snarf.in: Never generate an empty file. (Thanks to
Richard Polton.)
* gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
gh_new_procedure5_0): Specify argument types, to appease C++
compilers. (Thanks to Brad Bowman.)
Bug reports from Russ McManus:
* guile-snarf.in: If the CPP environment variable is set, use that
as the C preprocessor, instead of the preprocessor autoconf
found.
* snarf.h (SCM_PROC): Cast the function pointer passed to
scm_make_gsubr, to satisfy C++.
* gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
Use the handler passed, instead of ignoring it and using
gh_standard_handler. (Thanks to Etienne Bernard.)
1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
* ports.h: Put text after #endif in comment. (Thanks to Nicolas
Neuss.)

copyright years.
* script.c (scm_compile_shell_switches): Define
use-emacs-interface in the root module, so the repl code can see
it. See today's change to top-repl in ice-9/boot-9.scm.
* filesys.c (set_element, get_element): Make sure that `element'
is a cell before applying SCM_FPORTP to it. (Thanks to Jost
Boekemeier and Jorgen "forcer" Schaefer.)
1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
* chars.c (scm_charnames): In ASCII character name table, make
newlines print as #\newline by default, not #\nl.
* Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
alphabetical order. Oh thrills. But it helps me know how far
along in the compilation I am.
* Makefile.in: Regenerated.
1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
* unif.c (scm_raprin1): Changed print syntax for byte vectors from
#bytes(...) to #y(...), and syntax for short vectors from
#short(...) to #h(...). This may seem nutty, but, like the other
uniform vectors, byte vectors and short vectors want to have the
same print and read syntax (and, more basic, want to have read
syntax!). Changing the read syntax to use multiple characters
after the hash sign breaks with the conventions used in R5RS and
the conventions used for the other uniform vectors. It also
introduces complexity in the current reader, both on the C and
Scheme levels. (The Right solution is probably to change the
syntax and prototypes for uniform vectors entirely.)
1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
Don't use local_fgets on sockets; ftell doesn't work on sockets.
(Thanks to Jorgen "forcer" Schaefer.)
* ports.h (SCM_NOFTELL): New flag.
* fports.c (local_fgets): If it's set, use the generic fgets.
* socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
* script.c (scm_compile_shell_switches): Add handling of -q switch
(inhibit loading of user init file).
(scm_shell_usage): Add usage text for -q switch.
(scm_compile_shell_switches): Always load user init file first if
it is loaded at all.
1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
* stime.c: The CPP hair to determine a value for CLKTCK is weird,
and is now broken under NetBSD. I can't fathom what it's trying
to do, so I've replaced it with something that I do understand,
which seems to work, and which isn't broken on NetBSD. "Progress?
You Decide." (Thanks to Perry Metzger.)
* regex-posix.c (scm_regexp_exec): Add a cast to remove a
signed/unsigned comparison.
1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
Warning fixes from Greg Harvey:
* unif.c (scm_array_set_x): initializer for pos
* throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
* struct.c (scm_struct_ref, scm_struct_set_x): Added
initializers for field_type, since EGCS so desparately wants to
play dumb
* debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
when GUILE_DEBUG is defined.
* dynwind.h (scm_wind_chain): Same.
* ports.h (scm_pt_size, scm_pt_member): Same.
* print.h (scm_current_pstate): Same.
* procs.h (scm_make_cclo): Same.
1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
Handle short and long long uniform arrays properly. (Thanks to
Clark McGrew.)
* ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
raeql_1): Add cases for scm_tc7_svect (short vectors) and
scm_tc7_llvect (long long vectors).
Change the way libguile and boot-9.scm are timestamped, to try to
get rid of these spurious mismatch warnings. Now both
libguile/versiondat.h and ice-9/version.scm are generated directly
by the configuration process, rather than having version.scm
generated directly, and libguile/versiondat.h generated by the
Makefile, which is generated by configure. It seems that
sometimes the Makefile would change, but versiondat.h depends on
Makefile.in, not Makefile, so it wouldn't get rebuilt.
* Makefile.am (versiondat.h): Target removed; this is generated
directly by the configure script now.
(BUILT_SOURCES): Remove versiondat.h.
* versiondat.h.in: New file, transformed by the configure script
into versiondat.h.
* Makefile.in: Regenerated.
* (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
SCM_CAUTIOUS; this way, 1) there's only one version of each flag
to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
if we want to use them in a header file some day, we can. (Thanks
to Michael Livshin.)
* stime.c (scm_get_internal_real_time): Do the arithmetic using
SCM numbers, so we won't have rollover problems; the range of a
signed long in milliseconds is about 25 days. (Thanks to Karl
Hegbloom.)
Don't redefine sleep and usleep; fix this problem now.
* coop.c (sleep, usleep): Remove declarations; we don't use or
redefine these any more.
(scm_thread_usleep, scm_thread_sleep): New functions which do the
job of usleep and sleep in a thread-friendly way. We can use
these in the rest of Guile. Define versions for systems both with
and without iselect.
* threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
* scmsigs.c (usleep): Clean up oddities declaring usleep; since
we're just using it, not redefining it, we can use a K&R style
declaration here.
(sleep): Declare this, too, if the system hasn't.
(scm_sleep, scm_usleep): Use scm_thread_sleep and
scm_uthread_sleep if they're available; otherwise, just call the
system functions.
* scmconfig.h.in: Regenerated.
* coop.c (scm_thread_sleep): Make `slept' an unsigned long.
* coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
* threads.c: Doc fix.
The argument type of usleep varies from system to system,
as does the return type. We really shouldn't be redefining usleep
at all, but I don't have time to clean that up before the 1.3.
release. It's on the schedule for afterwards. (Thanks to Julian
Satchell.)
* coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
definition.
* scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
* scmconfig.h: Regenerated.
* simpos.c (scm_software_type): Procedure deleted. This isn't the
right way to handle system variation. Autoconf's approach is the
way and the light.
* simpos.h (scm_software_type): Declaration deleted.
* script.c (scm_find_executable): Don't test if unix is #defined
here; first, NetBSD doesn't #define it, and second, it's the wrong
way to go about these things. (Thanks to Perry Metzger.)
(dld_find_executable): Delete this MSDOS support code. This isn't
the way we want to support this; it needs to be rethunk at a
larger scale.
* genio.c (scm_do_read_line): Don't just politely check that the
line was either non-empty or EOF. Abort if it's empty and not
EOF.
1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
* scmconfig.h.in: Regenerated.
* libguile.h: Don't omit the dynamic linking functions. (Thanks
to Greg Badros.)
* genio.c (scm_do_read_line): Count lines correctly when the file
doesn't end in a newline.
1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
* genio.c (scm_do_read_line): Maintain the line count correctly.
(Thanks to Harvey J. Stein and Greg Harvey.)
* gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
requires ANSI now.
* numbers.c (big2str): Protect t from garbage collection until
we're done. (Thanks to Gary Houston.)
1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
* Makefile.am (libguile_la_LDFLAGS): Increment shared library
version number.
* Makefile.in: Regenerated.
* fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
SCM_P macro.
Do magic to mix reads and writes on stdio FILE-based ports.
(Thanks to Christian Lynbech.)
* fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
New macros.
(pre_read, pre_write): New functions.
(local_fgetc, local_fgets, local_ffwrite, local_fputc,
local_fputs): Call them.
(local_fflush): Mark the port as ready for reading and writing.
(scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
flags on new port objects. This might not be accurate --- who
knows what state the FILE * is in when we get it --- but it won't
do extraneous calls to fflush or fseek, so it's no worse than the
behavior before this change.
* ports.h: Add comment.
Centralize the creation of port objects based on stdio FILE * in
fports.c; don't just throw them together anywhere.
* fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
what the rest of Guile wants. Don't set the revealed count;
that's only appropriate for stdin, stdout, stderr.
(scm_standard_stream_to_port): This function does set the revealed
count.
* init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
not scm_stdio_to_port.
* filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
* fports.c (scm_open_file): Same.
* posix.c (scm_pipe): Same.
* socket.c (scm_sock_fd_to_port): Same.
* ioext.c (scm_fdopen): Same.
(scm_freopen): Moved from here to...
* fports.c (scm_freopen): ... here. This is really something that
munges the internals of an fport, so it should go here.
* fports.h (scm_stdio_to_port): Adjust prototype.
(scm_standard_stream_to_port, scm_freopen): New protoypes.
* ioext.h (scm_freopen): Prototype removed.
* filesys.c (set_element, get_element): This can work on both pipe
and file ports, so use SCM_FPORTP to typecheck, instead of testing
for scm_tc16_fport.
* scmconfig.h.in: Regenerated.
Change the definition of the functions in scm_ptobfuns so that
they get passed the port object, not the port's stream.
* ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
* gc.c (scm_gc_sweep): Pass the port itself to the free function.
* genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
Pass the port itself to the scm_ptobs function.
* ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
scm_generic_fgets): Same.
(putc_void_port, puts_void_port, write_void_port, flush_void_port,
getc_void_port, fgets_void_port, close_void_port): Just change the
argument names; these functions don't really do anything.
* fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
port as an argument, and use SCM_STREAM to get the stdio FILE *.
Also, use prototyped definitions, and get rid of the extra
declarations.
(scm_fptob, scm_pipob): We don't need casts here any more.
* strports.c (prinstpt): Use prototype declarations.
(stputc, stwrite, stputs, stgetc): Take the port as an argument,
and use SCM_STREAM to get the string info. Also, use prototyped
definitions, and get rid of the extra declarations.
* vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
noop0): Same.
* ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
prototype; it's okay (preferred, even!) to use ANSI C in Guile.
* fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
scm_fgets, for consistency.
(scm_fptop, scm_pipob): References updated.
1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
Include the source location in error messages for scripts.
* init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
stack is still there when we catch the error.
* throw.c (handler_message): If we are handling an error with a
message, then put together the proper arguments and call
scm_display_error, instead of scm_display_error_message. That
displays source location, if it can find it.
1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
* gc.c (scm_unprotect_object): Change this so that calls to
scm_protect_object and scm_unprotect_object nest properly.
(scm_protect_object): Doc fixes.
* strings.c (scm_string_set_x): Require the argument to be a
writable string, not a substring or a symbol.
* strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
(Thanks to John Redford and Charbel Jacquin.)
* scmconfig.h.in: Regenerated; ../acconfig.h has changed.
1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
* eval.c (safe_setjmp): Remove this misunderstanding.
(ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
ordinary setjmp.
1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
* libguile.h: Mark these as C declarations, for compilation by C++
compilers.
* snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
__cplusplus clause. I seriously doubt this ever worked the way
the author seems to have intended.
1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
Utterly needless cleanups to hopelessly messy code.
* ports.c: Doc fixes.
(scm_fflush): Moved to ...
* genio.c (scm_fflush): ... here, amongst all the other port
method invocation functions.
* genio.h, ports.h: The prototype moves too.
1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
* backtrace.c (display_error_body): The current frame does not
always have a parent frame; consider a function called directly
from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
Stachowiak.)
* alloca.c (alloca): Undo yesterday's changes, and simply call
malloc directly for storage, and abort if we don't get what we
want. The situation is much simpler --- just call malloc. Emacs
has bizarre/evil requirements (signal handlers might malloc unless
you set this global flag, so you have to set the flag around all
calls to malloc) which we are certainly not going to conform to,
so we can do the simple and obvious thing.
* coop.c (coop_condition_variable_wait): Make this function
static. It's only useful internally --- you should never just
wait on a condition variable.
* coop-defs.h (coop_condition_variable_wait): Delete prototype.
1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
* unif.c (scm_array_set_x): Accept any kind of number as an
element for a uniform vector of doubles. This is more consistent
with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
* alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
works; I can't conveniently test it myself. (Thanks to Dvid
Tillman for the bug report.)
* init.c: Doc fixes.
* init.c (invoke_main_func): Load the startup files (boot-9.scm)
from here, not from scm_compile_shell_switches (which is a pretty
dumb place to do it).
(scm_load_startup_files): New function.
(scm_ice_9_already_loaded): Variable moved to here from script.c.
* script.c (scm_compile_shell_switches): Don't load the startup
files here.
(scm_ice_9_already_loaded): Variable moved.
* init.c (scm_load_startup_files): Prototype for new function.
* gh_init.c (gh_enter): Doc fix.
1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
Some anti-warning changes from Greg Harvey.
* gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
warnings when it doesn't understand our NORETURN declarations in
error.h.
* posix.c (scm_mknod): Similar.
1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
* posix.c (scm_getpwuid): If we can't find an entry, return our
own message, instead of using scm_syserror --- the getpwMUMBLE
functions don't set `errno' to anything interesting.
1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
Get rid of warnings from the cooperative threading system.
* threads.h (scm_single_thread_p, scm_yield,
scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
scm_wait_condition_variable, scm_signal_condition_variable): Add
prototypes for these Scheme-visible functions.
* coop-defs.h (coop_next_runnable_thread,
coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
Prototypes for these here, even though they're from iselect.c.
(coop_condition_variable_wait, coop_join): Add prototypes.
* coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
scm_threads_free_condvar): Make these smob functions static.
* coop-threads.h (coop_init): Give this a real prototype.
* coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
(coop_next_runnable_thread): No need to provide prototype; it's in
coop-defs.h.
* scmconfig.h.in: .detarenegeR
* iselect.c, threads.c: Doc fixes.
1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
* Makefile.in: Regenerated with a patched automake, to get
dependency generation right when using EGCS.
* inet_aton.c (inet_aton): Add prototype, to remove compiler
warning. (Thanks to Robert Pluim.)
* inet_aton.c (inet_aton): Reassure the compiler that the
arguments to the <ctype.h> macros are all unsigned characters, not
signed characters.
1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
Getting rid of more warnings...
* iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
today's change to ../configure.in.
* scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
* scmconfig.h.in: Regenertaded.de.,.__
* stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
(scm_localtime, scm_mktime): Use a const char * to manipulate the
time zone name.
* readline.c: Doc fix.
(rl_cleanup_after_signal, rl_free_line_state): Make these static.
* readline.h (scm_filename_completion_function): Add prototype.
(scm_init_readline): Make this into a prototype.
* readline.c (scm_filename_completion_function): Use SCM_PROC to
declare this, instead of calling scm_make_subr manually.
1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
* readline.h (scm_init_readline): Add prototype for this.
(scm_init_readline): Make this a real prototype.
1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
Warning fixes from Maciej Stachowiak:
* backtrace.h (scm_display_application, scm_backtrace): Add
prototypes.

* fluids.h (scm_fluid_p): Add prototype.
* procprop.c (scm_i_procedure_arity): Make this function static.
* regex-posix.c (scm_regexp_error_msg): Make this function static.

* scmsigs.h (scm_usleep): Add external prototype.
* script.h (scm_init_script): Use prototype, not K&R decl.
* stacks.h (scm_stack_id): Add external prototype.
* symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
1998-09-30 Mark Galassi <rosalia@cygnus.com>
* gh.h: took out the definitions of vset and vref, since they are
replaced by the proper vector routines that correspond to the R4RS
procedures.
1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
* snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
third argument, a C expression that should result in a SCM value,
which is used to initialize the variable. Reimplemented
SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
Stachowiak.)
* version.h (scm_libguile_config_stamp): Add prototype.
(From Maciej Stachowiak.)
1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
* eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
(force 9) is tried. (Thanks to Karl M. Hegbloom.)
1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
* print.c (scm_iprin1): Rather than having one i, and using it in
several places, declare a fresh i local to each block where it is
used, and give it a signedness appropriate to its use in each case.
(scm_iprlist): Same.
* print.c (scm_iprin1): Add cast to avoid unsigned/signed
comparison warnings.
* print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
signed/unsigned clashes.
* posix.h (scm_tmpnam): Added prototype.
* objects.h (scm_set_object_procedure_x, scm_make_class_object,
scm_make_subclass_object): Add external prototypes.
* numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
comparison is okay here.
* numbers.c (scm_istr2int): Add cast; len is known to be positive.
* numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
(true, but confusing) fact that -1 == ((unsigned) 0 - 1).
* numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
signed/unsigned.
* load.c (swap_port): Make this function static.
* load.c (scm_search_path): Make max_path_len and max_ext_len
unsigned, since they're compared against string sizes.
* load.c (init_build_info): Make i unsigned.
* ioext.h (scm_read_line): Add prototype.
* hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
scm_hash_fn_remove_x): Make hash bucket index local variable k
unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
accurately as possible.
* gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
comparisons, and range checking to make sure those casts are
harmless.
* stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
signed/unsigned comparisons.
* smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
avoid signed/unsigned comparisons.
* smob.h (scm_numsmob): Change extern declaration to match.
* ports.c (scm_numptob): Make this an int, not an scm_sizet, to
avoid signed/unsigned comparisons.
* ports.h (scm_numptob): Change extern declaration to match.
(scm_current_load_port, scm_set_port_line_x,
scm_set_port_column_x): New prototypes.
* gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
test code, and it causes warnings.
* gh.h (gh_int2scmb, gh_uniform_vector_length,
gh_uniform_vector_ref): Added prototypes.
* Makefile.am (libguile_la_SOURCES): Include Scheme-level
debugging support unconditionally. That's backtrace.c, stack.c,
debug.c, and srcprop.c.
(EXTRA_libguile_la_SOURCES): Omit those from here.
* Makefile.in: Regenerated.
1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* options.c (scm_options): Bugfix: Allow empty list of options!
* debug.c, debug.h (scm_single_step): Removed.
(scm_with_traps): New procedure. This procedure could easily be
written in Scheme but needs to be highly optimized.
* eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
* eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
Check SCM_TRAPS_P before trapping.
1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
Changes to avoid signed/unsigned comparison warnings.
* gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
(scm_gc_sweep): Make n and j local to the blocks they're used in,
so they can have appropriate types for each application. Make i
signed. Use initializers in some spots. I'll probably pay for
all this tweaking.
(scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
(scm_must_realloc): Make nm unsigned.
(init_heap_seg): Make new_seg_index and n_new_objects signed.
(scm_init_storage): Use prototype-style definition, and make the
argument unsigned.
* gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
* filesys.c (scm_readlink): Make local vars rv and size ints, to
avoid signed/unsigned comparison warnings, and because the return
value of readlink may be -1. Don't bother casting the third
argument to readlink.
* filesys.c (scm_dirname, scm_basename): Move these to their own
page, at the end of the file.
* filesys.h (scm_dirname, scm_basename): Add prototypes for these.
* eval.h (scm_eval_options_interface): Add external prototype for this.
* eval.c (scm_eval_options_interface): Use prototype-style def'n.
* eval.c (scm_lookupcar1): Make this static.
* dynl.h (scm_registered_modules, scm_clear_registered_modules):
Make these prototype declarations, not K&R-style.
* chars.c (scm_tables_prehistory): Add cast, to remove signed/
unsigned comparison warning.
* appinit.c: File removed. It had a single function in it, empty,
whose reason for existence is explained in no documentation or
comment. I think it's there as a default for some Tcl-style
initialization, but Tcl abandoned that approach a while ago.
* Makefile.am (libguile_la_SOURCES): Remove appinit.c.
(BUILT_SOURCES): Remove appinit.x.
* Makefile.in: Regenerated.
1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
* Makefile.in: Regenerated using the last public version of
automake, not the hacked Cygnus version.
1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
Remove Totoro kludge.
* Makefile.in, scmconfig.h.in: Regenerated.
* init.c, readline.c: Don't check if TOTORO is #defined.
1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
* Makefile.am: Adjust for new thread configuration system.
(INCLUDES): Include the value of THREAD_CPPFLAGS.
(guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
THREAD_LIBS.
(THREAD_LIBS): Definition deleted; automake will generate such
things automatically.
* Makefile.in: Regenerated.
1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
Simplify smob and port marking; set the mark bit in the generic
marking code, and make marker routines only responsible for
turning up outgoing pointers.
* gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
before calling the marking function. Don't call the marking
function if it's zero.
* markers.c (scm_mark0): Just return #f. This function isn't
necessary at all now, but it's harmless to call it. We'll leave
it in so other folks' code doesn't croak at link time.
(scm_markcdr): Don't call SCM_SETGC8MARK.
* async.c (mark_async): Don't call SCM_SETGC8MARK.
* dynl.c (mark_dynl_obj): Same.
* root.c (mark_root): Same.
* srcprop.c (marksrcprops): Same.
* unif.c (markra): Same.
* variable.c (scm_markvar): Same.
* ports.c (scm_markstream): Same.
(void_port_ptob): Specify zero for our marking function.
* debug.c (debugobjsmob): Same.
* dynwind.c (guardsmob): Same.
* filesys.c (dir_smob): Same.
* fluids.c (fluid_smob): Same.
* fports.c (scm_fptob, scm_pipob): Same.
* mallocs.c (mallocsmob): Same.
* regex-posix.c (regex_t_smob): Same.
* smob.c (freecell, flob, bigob): Same.
* threads.c (thread_smob, mutex_smob, condvar_smob): Same.
* throw.c (jbsmob, lazy_catch_funs): Same.
1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
* eval.c (scm_copy_tree): Reverted last change: `eval' uses
scm_copy_tree on code in order not to let memoized code to leak
out. Thus, scm_copy_tree needs to copy vectors as well since
quasiquote can introduce evaluated code also inside vector
constants.
1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
* eval.c (scm_copy_tree): Removed ability to copy vectors.
* gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
gh_doubles2dvect.)
* unif.c: Say that ivect and uvect are of type signed and unsigned
long instead of int in commentary so that it correctly describes
the implementation.
1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
* stime.c: Removed declaration of strptime. (It should be
declared by the system headers. If it turns out that some systems
don't, we'll handle that then.) (Thanks to Greg Troxel.)
* stime.h: Renamed TIMEH --> STIMEH
* backtrace.c (scm_display_error, scm_display_backtrace): In order
to increase portability, don't use structure assignment.
(Thanks to Nicolas Neuss.)
* iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
portability.
(finalize_fd_sets): Added empty statement after last case label.
(Thanks to Nicolas Neuss.)
* gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
Nicolas Neuss.)
Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
* init.c, readline.c: OK, I won't have these readline.x bug
reports anymore. We've had them since April. The current reason
is a completely unintelligible failure of totoro.red-bean.com to
do the test for rl_getc_function in libreadline correctly. This
kludge overrides the test if we're on totoro so that the snapshot
generation process can work.
* readline.c: Define a strdup replacement if not existent on system.
1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
* vectors.c, vectors.h (scm_make_vector): Removed third argument.
This change makes scm_make_vector R5RS compatible. We cannot keep
the third argument since people want to be able to deduce the form
of the C function call only by looking at R5RS. (At the same time
we have removed some unnecessary complexity!)
* eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
argument in call to scm_make_vector.
1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
This macro is useful in applications.
1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
* load.c (scm_internal_parse_path): Renamed from scm_parse_path.
(scm_parse_path, scm_search_path): New Scheme level procedures.
* load.h (scm_internal_parse_path, scm_parse_path,
scm_search_path): Declared.
1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* filesys.c (dirname, basename): New procedures.
* init.c (scm_boot_guile_1): Removed condition around
scm_init_options.
* dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
new data type (guards) for representation of C level guards and
data on the wind chain.
(scm_internal_dynamic_wind): New function.
* dynwind.h: Declare scm_internal_dynamic_wind.
* root.h (scm_root_state): Added scm_cur_loadp.
* root.c (mark_root): Added comment about cur_loadp.
* load.c: #include "dynwind.h";
(scm_primitive_load): Use scm_inner_dynamic_wind to update
scm_cur_loadp.
* init.c (scm_init_standard_ports): Initialize scm_def_loadp.
* ports.c (current-load-port): New procedure.
1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* ioext.c (scm_isatty_p): Accept any kind of data as argument. If
not a tty, return #f.
* regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
to Julian Satchell and Roland Kaufmann.)
* gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
(gh_write): Added declaration. (Thanks to Eiichi Takamori.)
1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
* debug.h, debug.c (scm_start_stack): New function. Implements
the guts of old scm_m_start_stack.
* debug.c (scm_m_start_stack): Use scm_start_stack.
* init.c (scm_start_stack, scm_restart_stack): Renamed to
start_stack and restart_stack. (These have static scope.)
1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* readline.c (rl_cleanup_after_signals, rl_free_line_state): New
readline functions to come in release 2.3. (Thanks to Chet
Ramey.)
(handle_errors): Use the above functions.
1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* readline.c: Improvements for readline support: Handle errors
better; Implement before-read-hook.
1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* init.c (scm_boot_guile_1), readline.c: Test for
HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
assure that we have version >= 2.1.)
1998-05-11 Mikael Djurfeldt <mdj@kenneth>
* readline.c (scm_readline): Defer interrupts while we're calling
readline.
* readline.c (scm_add_history): Bugfix: Do strdup before giving
away the string to add_history.
(completion_function): Do completion for readline. (Thanks to
Andrew Archibald.)
(scm_filename_completion_function): New procedure: Filename
completer.
(current_input_getc): New function. Use this one instead of
standard getc from readline.
* throw.c, throw.h (scm_handle_by_throw): New function: This
handler throws errors to next handler on the dynwind chain.
1998-05-09 Mikael Djurfeldt <mdj@kenneth>
* scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
used.
1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* procprop.c (scm_i_procedure_arity): New function. Returns arity
of procedure.
(scm_procedure_properties): Modified to return arity together with
other properties.
(scm_procedure_property): Added the read-only property `arity'.
(scm_set_procedure_property_x): It is an error to set the `arity'
property.
* gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
* procprop.h (scm_sym_arity): New symbol.
* objects.c (scm_set_object_procedure_x): New procedure: Use this
to set the dispatch procedure of an operator or entity object.
* objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
Made procedure slots read-only.
* eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
scm_tcs_cons_gloc case in zero args switch; Fixed args
construction for operators in scm_tcs_cons_gloc case in two args
switch.
1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* fluids.c: Removed use of assert.h (in order to avoid
__eprintf).
* Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
* dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
* eval.c (SCM_CEVAL): Do more thorough argument checking. This
change makes the evaluator safer at the cost of evaluation speed.
It handles the case when the user has added a non-immediate
improper end of the application form, e.g., `(+ 0 . x)'.
(Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
minimize the extra cost as much as possible. The new code is
enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
problem with structs planted directly in the code (e.g. by a
macro). This no longer causes segmentation fault. (Thanks to
Eric Hanchrow.)
* eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
arg `proc' in order to be able to throw errors; New argument
checking code.
* Removed extra #include "debug.h"
1998-04-25 Mikael Djurfeldt <mdj@kenneth>
* scmsigs.c: Declare usleep as returning void on some systems.
(scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
Satchell.)
* coop.c (usleep): Return void on some systems.
1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
* coop.c: Changed return type of usleep to int.
* scmsigs.c (scm_usleep): New procedure; Declare usleep if it
isn't found in the OS.
* iselect.h: #define scm_internal_select select if GUILE_ISELECT
isn't enabled. (Thought that I had made this change ages ago...)
* iselect.c: Declare bzero if not defined by OS.
1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* dynl.c (scm_must_free_argv): Fixed memory leak due to negated
condition. (Thanks to John Tobey.)
* continuations.c (scm_make_cont), debug.c (scm_make_memoized,
scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
A section.
* __scm.h: Start the long-term project of moving to POSIX threads.
Phase 1: Classification of all critical sections.
(SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
for A sections. (See comments in __scm.h for details.)
* dynl.c: Only check that HAVE_DLOPEN is defined before loading
dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
(libpath.h, versiondat.h): Replaced dependency on Makefile with
dependencies on $(srcdir)/Makefile.in
$(top_builddir)/config.status in order to avoid circularity.
* script.c (scm_compile_shell_switches): Bugfix: Don't discount i
from argc if argc was 0 initially.
* Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
in generation of libpath.h.
1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
* Makefile.am (libguile_la_LDFLAGS): Bumped version number of
libguile from 2 to 3.
1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
* Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
1998-04-13 Mikael Djurfeldt <mdj@kenneth>
* ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
scm_set_port_column_x, scm_port_filename,
scm_set_port_filename_x): Removed optional arguments. Added
proper argument checking.
* eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
stack size in machine words.
* unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
to Ole Myren R<>hne.)
1998-04-12 Mikael Djurfeldt <mdj@kenneth>
* socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
* gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
Caradoc-Davies.)
* eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
procedure apply: Copy argument lists before pushing them unto the
environment so that the environment won't get mutated due to
manipulation of procedure arguments. This should perhaps be
regarded as a temporary solution until someone finds a more
efficient one. (Thanks to Maciej Stachowiak.)
1998-04-10 Mikael Djurfeldt <mdj@kenneth>
* script.c (scm_compile_shell_switches): Use "guile" as default
zero arg if argc is NULL.
1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
* script.c (scm_compile_shell_switches): Allow NULL argv if argc
is zero. (Thanks to Dirk Herrmann.)
1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
* ports.c (scm_add_to_port_table): First line is now line 0
(was 1). (Interface changed according to suggestion by Per
Bothner.)
* backtrace.c (display_header): Add 1 to line and column numbers
when presenting them to the user.
* eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
from debug.c --> eval.c
* eval.h, eval.c (scm_eval_options_interface): New options
interface.
(SCM_EVAL_STACK): New option: Size of newly created stacks,
i.e. stacks for new threads.
* coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
* eval.c (unsafe_setjmp): Removed with #if 0.
* gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
warning.
* eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
to avoid compiler warnings.
* dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
* throw.c (handler_message): Print message on current error port
instead of default error port. (Thanks to Maciej Stachowiak.)
Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
* ports.c (scm_add_to_port_table): allocate in units of
struct scm_port_table *, not struct scm_port_table.
* posix.c (scm_close_pipe): remove the port from the port table
and mark as closed.
Thanks to Rob Engle for both fixes.
1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* throw.h: Removed jmpbuf arg in scm_catch_body_t.
* backtrace.c (display_error_body, display_backtrace_body),
coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
(invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
functions.
* throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
don't receive the jmpbuf arg anylonger.
(scm_catch): Don't accept a #f tag.
(scm_throw): Check that key is a symbol.
(scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
* async.c (async_pending): Removed declaration.
1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* dynwind.c (scm_wind_chain): New debug function.
* coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
extra layer of functions around the body and handler of a thread.
This extra layer makes sure that the handler is called in the
dynamic context of the surround (= empty dynwind list), but under
the *dynamic root* of the body. We can not use the dynamic root
of the surround since that root belongs to another thread => stack
is not handled correctly. It may seem ugly to use this extra
layer, but the extra cost in terms of execution time is really
negligible compared to the total amount of time required to create
a thread, and it would reduce maintainability to duplicate the
crucial and complicated steps performed by cwdr.
* __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
(SCM_ALLOW_INTS): Added thread switching code before interrupts
get re-enabled. The important effect of this is that interrupts
are blocked during thread switching so that thread data structures
don't risk getting messed up by an unfortunate signal.
(SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
seems to do more aggressive optimization which actually move
instructions around in these macros in a fatal way. Therefore:
Introduce Anthony's SCM_FENCE macro! (And I who thought he was
just superstitious...)
(SCM_TICK): Maybe do a context switch and take care of asyncs.
This macro should be used instead of SCM_ASYNC_TICK since the
latter doesn't do context switches any more.
* eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
instead of SCM_ASYNC_TICK.
* coop.c, iselect.c: Since thread switches are now performed with
interrupts masked, we can't use the old mechanism of delivering
signals immediately when they arrive. Signals must instead be
delivered when the asyncs run *after* the end of the critical
section in scm_internal_select. But this also means after context
switch so that the signal will be delivered to a different thread.
To avoid this, I have changed the protocol of
coop_wait_for_runnable_thread and friends so that they are allowed
to return the original thread. So, if a signal arrives during
scm_internal_select, we won't any longer be forced do a context
switch, but can remain in the same thread and deliver the signal
to it.
* async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
scm_asyncs_pending and made it global.
* iselect.c: Small fixes.
* coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
coop_condition_variable_init, coop_condition_variable_wait,
coop_condition_variable_signal): Changed return type from `void'
to `int'. This is to adhere closer to the pthreads interface.
This, in turn, is part of an attempt to provide C versions of the
mutex and condition variable primitives which can be part of a
frontend to COOP or pthreads.
* coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
coop_condition_variable_destroy): New functions.
* coop-threads.c (scm_wait_condition_variable): Use
coop_condition_variable_wait_mutex.
* coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
Definitions moved to coop-defs.h.
* coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
scm_cond_destroy): New C interface to mutecis and cond vars.
1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
* iselect.c: Now several threads can wait on the same file
descriptor. The behaviour is compatible with OS select: All
threads waiting for the fd return with the same status.
1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* coop-threads.c, threads.h (scm_spawn_thread): New function.
Can spawn a thread from application C code.
1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
gh_doubles2scm): New functions.
1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
* gh_eval.c (gh_eval_str): cleanup -- threw out the old
commented-out version of gh_eval_str()
Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
* socket.c (scm_bind): free soka after use.
Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
* stime.c (tzvar): new variable.
(setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
avoid memory leaks when allocating.
1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
* iselect.h: Some systems require <sys/types.h> to get the FD_SET
macro definitions.
* gc.c, tags.h: Doc fixes.
1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* eval.c (macro-eval!): Removed. This function was a design bug.
It allowed memoized code to leak out to the scheme level. Most
things that you could do with `macro-eval!' can be done with
`local-eval'.
1997-12-20 Tim Pierce <twp@skepsis.com>
* fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
scm_fgets now depends on ftell(3) to know how many bytes were
read. Sigh.
1997-12-15 Tim Pierce <twp@skepsis.com>
* gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
dealing with strings.
1997-12-13 Tim Pierce <twp@skepsis.com>
Make %read-line more suitable for implementing read-line efficiently.
* ioext.c (scm_read_line): Strip the terminating newline from a
string, and return a cons of the string and its terminator.
* fports.c, fports.h (scm_fgets): Add `len' argument. The length
of the string that is read is stored in this memory location.
* ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
* genio.c, genio.h (scm_do_read_line): Update caller.
* ports.h (scm_ptobfuns): Update typedef.
* fports.c (scm_fptob, scm_pipob): Update struct.
1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* filesys.c (set_element): Return file descriptor.
(fill_select_type): Return the highest file descriptor.
(scm_select): Tell select about the highest file descriptor. On
some systems the SELECT_SET_SIZE can be as much as 128 bytes.
Therefore the extra overhead for calculating the maximum fd seems
to be more than compensated. Is this correct? In any case,
scm_internal_select will be much faster with this info.
(scm_select, fill_select_type, set_element): Don't accept any kind
of object in the file descriptor list or vector.
1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* iselect.c (finalize_fd_sets): Bugfix.
1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
when using scm_internal_select (since we might switch to another
thread).
Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
* simpos.c (scm_system): always define: use sysmissing if not
available. Check for HAVE_SYSTEM instead of _Windows (does
Windows lack system or does it have an unusable one?).
Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
Let the argument be optional: if not supplied, call system(NULL).
* ports.c (scm_close_port): relax the type check from OPPORTP to
PORTP; closing a closed port is allowed.
1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
* fports.c (scm_fgets): Return if the last char in a chunk is
newline. When fgets returns a string whose length is `size-1', it
is ambiguous whether a whole line was retrieved, so we must check
explicitly whether a line terminator is present.
1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
before taking the CDR. (Thanks to Harald Meland.)
* filesys.c (scm_stat): Slightly optimized.
Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
* ports.c (scm_close_port): Make sure the port is open before
trying to close it.
* guile-snarf.in: Pass args through to gcc in a way that preserves
whitespace boundaries. (Thanks to Greg Badros.)
1997-12-02 Tim Pierce <twp@skepsis.com>
* stacks.c (scm_frame_procedure): Reverse the logic in the return
statement. (Thanks to Doug Evans for pointing this out.)
1997-12-01 Tim Pierce <twp@skepsis.com>
* scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
* coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
errno macro expansion of this field name. (errno is a C
preprocessor macro on some systems.)
1997-11-29 Tim Pierce <twp@skepsis.com>
* iselect.c: Doc fix.
Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
* init.c (scm_start_stack): Removed initialization of
scm_the_last_stack_var.
* backtrace.h: Declare scm_the_last_stack_var.
* backtrace.c: Define scm_the_last_stack_var.
* root.c (mark_root): Don't mark the_last_stack_var.
* root.h (scm_root_state): Removed the_last_stack_var.
* throw.c: Added #include "fluids.h"
(ss_handler): `the-last-stack' is now a fluid.
* (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
--> the_last_stack_fluid.
* backtrace.c: Added #include "fluids.h"
(scm_init_backtrace): Initialize `the-last-stack' to a fluid.
(scm_backtrace): `the-last-stack' is now a fluid.
* init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
after scm_init_fluids.
1997-11-28 Tim Pierce <twp@skepsis.com>
* iselect.c: #ifdef USE_THREADS around thread-related includes.
* dynl-dl.c (sysdep_dynl_func): Check both USCORE and
DLSYM_ADDS_USCORE to decide whether to add an underscore.
1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* iselect.c (coop_next_runnable_thread,
coop_wait_for_runnable_thread): Disable interrupts so that no
async is executed before a potential error_revive.
(scm_internal_select): Disable interrupts during the parts of the
code which manipulate the sleep queue and the file descriptors.
1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* Makefile.am: Added iselect.c and iselect.h.
* coop.c (coop_qinit): Initialize fields used by
scm_internal_select.
(coop_qget, coop_qget, coop_tmp_queue): Made global.
(coop_next_runnable_thread): If GUILE_ISELECT enabled, use
replacement in iselect.c.
(coop_mutex_lock, coop_condition_variable_wait, coop_abort,
coop_join): If GUILE_ISELECT enabled, use
coop_wait_for_runnable_thread instead of
coop_next_runnable_thread.
(usleep, sleep): New replacements for system functions if
GUILE_ISELECT is enabled.
* coop-threads.h: Declare coop_wait_for_runnable_thread.
* coop-defs.h (coop_t): Added fields used by scm_internal_select.
* filesys.c: Added #include "iselect.h". Moved FD-macros to
iselect.h. Implement Scheme level `select' using
scm_internal_select. (See NEWS.)
* genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
* init.c: Call scm_init_iselect.
* iselect.h, iselect.c: New files. Implements
scm_internal_select. (See NEWS.)
1997-11-27 Tim Pierce <twp@skepsis.com>
Fix a memory leak in scm_read_line and a type cast bug in the ptob.
* fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
and scm_must_free, since ultimately the string returned will be copied
by scm_makfrom0str anyway. Also, read any characters that may have
been pushed onto the port with scm_ungetc.
* ports.c (scm_generic_fgets): Same as for scm_fgets.
* ioext.c (scm_read_line): Free string after Guilifying it.
* ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
1997-11-26 Anthony Green <green@hoser.cygnus.com>
* gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
* gh.h: Safely wrap prototypes for c++ usage.
1997-11-25 Mark Galassi <rosalia@cygnus.com>
* gh_test_repl.c (main_prog): changed invocation of gh_repl() to
gh_repl (argc, argv).
1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
* gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
and to invoke scm_shell().
(gh_launch_pad): took out the loading of boot-9.scm from here,
since it is probably best to let the user control that. In fact,
gh_repl() now invokes scm_shell() which does that.
1997-11-23 Mark Galassi <rosalia@cygnus.com>
* gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
invocation.
1997-11-22 Tim Pierce <twp@twp.tezcat.com>
* dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
yesterday's underscore patch. (Thanks to Marius Vollmer for
spotting this.)
1997-11-21 Tim Pierce <twp@twp.tezcat.com>
* dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
DLSYM_ADDS_USCORE is not defined.
1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
* gh_data.c (gh_uniform_vector_length):
(gh_uniform_vector_ref): started implementing the uniform types in
the gh_ interface.
1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
* regex-posix.c (scm_free_regex_t): Return size of regex_t instead
of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
* scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
configure.in was changed).
Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
* Makefile.am (modinclude_HEADERS): Include readline.h here.
* Makefile.in: Regenerated.
1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
* print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
OPORT is an `open' port, not an output port.
* filesys.c (scm_close, set_element, get_element, scm_chown,
scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
SCM_COERCE_OUTPORT to cope with the printstate/port magic.
* ports.c (scm_port_revealed, scm_set_port_revealed_x,
scm_close_port, scm_port_line, scm_set_port_line_x,
scm_port_column, scm_set_port_column_x, scm_port_filename,
scm_set_port_filename_x, scm_port_mode,
scm_close_all_ports_except, scm_set_current_output_port,
scm_set_current_error_port): Likewise
* ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
Likewise
* posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
* backtrace.c (display_backtrace_body): Likewise
* fports (scm_setvbuf): Likewise
* socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
scm_getpeername, scm_send, scm_sendto): Likewise
* unif.c (scm_uniform_array_write): Likewise
Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
Minor problems with substring-related tag changes.
* symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
exactly what we want to leave in to detect substrings.
(SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
* tags.h: Fix diagrams and comments describing the S tag bit;
remove vestigial remarks about the D tag bit.
(SCM_TYP7, SCM_TYP7S): Rephrased for readability.
* strings.c: Formatting tweaks.
* load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
variable first; then SCHEME_LOAD_PATH, with a warning message.
(scm_parse_path): New function.
* script.c: Doc fixes.
Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
Readline support, from Daniel Risacher.

(scm_boot_guile_1): Call scm_init_readline, if we have it.
* Makefile.am (libguile_la_SOURCES): Include readline.c.
* Makefile.in: Regenerated.
* scmconfig.h.in: Regenerated, after change to ../configure.
1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
* gh.h: gh_vector_set -> gh_vector_set_x
1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
* gh_data.c (gh_vector_set_x): changed name to make it consistent
with the ! -> _x mapping when going from Scheme to C.
1997-10-19 Mark Galassi <rosalia@cygnus.com>
* gh.h (gh_reverse):
(gh_list_tail):
(gh_list_ref):
(gh_memq):
(gh_memv):
(gh_member):
(gh_assq):
(gh_assv):
(gh_assoc): added these gh_ functions implemented as macros.
* gh_predicates.c (gh_null_p):
(gh_string_equal_p): added these two missing predicates.
* gh_list.c (gh_append):
(gh_append2):
(gh_append3):
(gh_append4):
(gh_set_car_x):
(gh_set_cdr_x): added these routines as I go through and try to
complete the picture R4RS functions that should be mirrored in the
gh_ interface.
Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* tags.h (scm_tc7_substring): Changed the comment and code to
conform with the changes below. Folks! We have suddenly two new
free tc7 codes!!! Jummy, jummy!
Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>

(SCM_TYP7D): Removed.
(scm_tc7_mb_string): Removed.
(scm_tc7_mb_substring): Removed.
* print.c (scm_iprin1): Handle char printing directly. Don't
handle mbstrings.
Don't include "mbstrings.h".
* symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
multi-byte flag.
Don't include "mbstrings.h".

gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
struct.c, threads.c, throw.c, unif.c, variable.c: Use new
("gen"-less) I/O function names.
* ports.c (scm_add_to_port_table): Don't set port's
representation.
* ports.h (scm_port_representation_type): Removed.
(scm_string_representation_type): Removed.
(struct scm_port_table ): Removed representation field.
(SCM_PORT_REPRESENTATION): Removed.
(SCM_SET_PORT_REPRESENTATION): Removed.
* genio.h: Use new function names.
* genio.c: Don't include "extchrs.h".
(scm_gen_putc, scm_gen_puts, scm_gen_write, scm_get_getc):
Removed.
(scm_putc, scm_puts, scm_lfwrite): No longer static.

1997-10-12 Mark Galassi <rosalia@cygnus.com>
* gh_test_repl.c (c_vector_test): same as gh_test_c.c
* gh_test_c.c (c_vector_test): some improvements on the vector
routines test.
* gh.h (gh_vector): this used to exist but do the wrong thing.
Now it (almost) does the right thing, though it takes a list
instead of the individual arguments. I need to see how it could
be done right.
(gh_list_to_vector): added this function as a macro. Corresponds
to Scheme's (list->vector ...).
(gh_vector_to_list): added this function as a macro. Corresponds
to Scheme's (vector->list ...).
* gh_data.c (gh_vector_ref): renamed from gh_vref to
gh_vector_ref, so that it resembles the Scheme routines more.
(gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
resembles the Scheme routines more.
(gh_make_vector): this used to be (stupidly) called gh_vector().
This is the right name, since it does the same thing as the Scheme
(make-vector ...) procedure.
Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
* ports.h: #include "libguile/print.h"
* eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
Some indentation fixes.
* objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
longer a user field; New field: class_flags.
* objets.c, objects.h: New metaclass: scm_metaclass_operator.
Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
* gh_data.c (gh_bool2scm): new function which replaces
gh_int2scmb(), which is now tagged as obsolete.
1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
* print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
macros should by convention not test for NIMPness.)
(SCM_COERCE_OPORT): Adjust indentation.
* print.c (scm_valid_oport_value_p): Adjusted indentation; Added
SCM_NIMP test before SCM_PRINT_STATE_P.
* struct.c, struct.h, gc.c: Renamed:
scm_struct_i_layout --> scm_vtable_index_layout
scm_struct_i_vcell --> scm_vtable_index_vcell
scm_struct_i_vtable --> scm_vtable_index_vtable
scm_struct_i_printer --> scm_vtable_index_printer
scm_struct_i_vtable_offset --> scm_vtable_offset_user
* struct.c (scm_print_struct): Use new printer slot; Default
printing: Also output hex code of vtable so that type identity
will be indicated as well.
(scm_init_struct): Updated required_vtable_fields to "pruosrpw";
Removed struct_printer_var; Removed struct-vtable-offset;
(vtable-index-layout, vtable-index-vtable, vtable-index-printer,
vtable-offset-user): New constants.
* struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
(scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
If this slot contains a procedure, use that to print structures of
the type represented by this vtable.
* print.c (scm_iprin1): Don't print arguments of macro
transformers. (They are always: exp env.); Bugfix: Unmemoize
transformer source with correct environment.
1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
Streamlining of call-with-dynamic-root:
* root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
there is now only one catch.
(cwdr_outer_body): Removed.
(cwdr_handler): New function.
(scm_internal_cwdr): New function to perform the function of cwdr
but take args that are more useful to C code. Also, the handler
is now invoked *outside* of the new dynamic root, like the docs
say. We no longer have to catch absolutely all errors, the caller
is responsible for using a handler that does not throw, if he
wants that.
(cwdr): Reimplemented in terms of scm_internal_cwdr.
* root.h (scm_internal_cwdr): New prototype.
Even more but risky streamlining:
* root.c (USE_STACKJMPBUF): New define to activate a stack-based
allocation of the jumpbuf of a root continuation. The changes
below are controlled by it. They are now deactivated.
(scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
the JMPBUF of the scm_rootcont to NULL before returning.
* gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
when they are non-NULL.
(scm_gc_mark): Likewise, mark only when non-NULL.
Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
* dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
* gc.c (scm_done_malloc): New function.
gc.h (scm_done_malloc): New prototype.
* print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
(struct scm_print_state) [revealed]: New field.
(scm_print_state_vtable): Make visible to the outside world for
type checking purposes.
(scm_valid_oport_value_p): New prototype.
* print.c (scm_valid_oport_value_p): New function to check whether
a certain value is acceptable as a port argument.
(scm_print_state_vtable): New variable.
(scm_free_print_state): Set `revealed' field to false.
(scm_iprin1): Call user supplied closure printer with
scm_printer_apply. Print in the traditional way when there isn't
one or when it returns #f.
(scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
Accept a port/print-state pair in addition to just a port.
(scm_prin1): Don't return the print_state to the pool when it has
been `revealed'.
(scm_printer_apply): Set `revealed' field of print_state to true.
(scm_init_print): Set scm_print_state_vtable.
(print_state_fluid, print_state_fluid_num): Removed.

Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
* Makefile.in: Regenerated with automake 1.2c.
Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
* ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
was looping endlessly.
Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
* strports.c (scm_eval_string): Don't close the port.
* stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
former returns a nice normal integer. (Thanks to Daniel
Risacher.)
Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
* Makefile.am (libpath.h): Include the value of the THREAD_LIBS
makefile variable as a build parameter called LIBS. The
build-guile program will use this, for the time being.
* Makefile.in: Regenerated.
Thanks to Shiro Kawai:
* gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
* ports.h (scm_ptobfuns): The fgets method returns a char *, not
an SCM.
* Makefile.in: Regenerated with automake 1.2a.
* script.c (scm_compile_shell_switches): If we hit the -c or --
arguments, don't set the car of (command-line) to scm_usage_name,
the prettified name of the guile executable; give it the full
path, the way shells usually handle $0.
Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
Scheme-level name `array-map' and renamed `serial-array-map' to
`serial-array-map!'.
* backtrace.c: Introduced exception handlers which now enclose
`display-error' and `display-backtrace' so that error reporting
won't get into infinite loops if an error occurs during displaying
of the error. This can very easily happen with user supplied
print call-back routines.
Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* ramap.c: Added alias `array-map!' for `array-map'. (Probably,
the names `serial-array-map' and `array-map' should be removed.)
Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
* init.c (scm_boot_guile_1): Added scm_init_objects ().
Added #include "objects.h"
* eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
Add #include "feature.h".
* Makefile.am (libguile_la_SOURCES): Added objects.c.
(modinclude_HEADERS): Added objects.h.
* ports.h (SCM_EOF_OBJECT_P): New macro predicate.
This test is needed at many places in the code and should be
abstracted. (Motivated by the need of this test in libguiletk.)
* ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
(scm_eval_string), load.c (scm_primitive_load,
scm_read_and_eval_x), gh_eval.c (gh_eval_str):
Use SCM_EOF_OBJECT_P.
* eval.c (scm_init_eval): Add feature `delay'.
Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* scmhob.h: Removed.
Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* list.h (SCM_LISTn): New macros. Make list creation in C code
prettier. The idea comes from STk.
* sequences.h, sequences.c, append.h, append.c: Removed. These
files implemented non-R4RS operations which would encourage
non-portable programming style and less easy-to-read code.
* Makefile.am (sequences.h, sequences.c, append.h, append.c):
Removed.
* libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
sequences.h, #include append.h.
* init.c (scm_boot_guile_1): Removed calls to scm_init_append and
scm_init_sequences.

* tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
and entities.
* smob.c (scm_smob_prehistory): Create two objectsmobs with
adjacent smob numbers.
Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* procprop.h: Added declaration of scm_i_inner_name.
* gsubr.c: New global symbol scm_i_inner_name.
* debug.c (scm_procedure_name): Try procedure property
`inner-name' if `name' fails.
* print.c (scm_iprin1): Use scm_macro_name.
* eval.c (scm_m_define): Give names to macros as well; Only the
first top-level definition gives a procedure/macro a name.
Otherwise confusing names can turn up in backtraces.
(SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
`name'; Give names to macros as well.
* procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
(scm_macro_transformer): Use SCM_CLOSUREP instead of
scm_closure_p.
Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* eval.c (macro?, macro-type, macro-name, macro-transformer): New
procedures;
(prinmacro): Removed. The code has been moved/merged into print.c
in order to decrease code redundancy. We want macros to print in
a way equivalent to procedures, and it would be silly to duplicate
the required code. (We don't want to maintain two places.)
(macrosmob): Print field is now a NULL pointer.
* eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
scm_macro_transformer): New prototypes.
(scm_tc16_macro): Declared.
* print.c (scm_iprin1): Added code for printing of macros. Macros
are now printed in a way equivalent to procedures.
Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
* procs.h (scm_closure_p): Added declaration.
Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
Shouldn't pass "heap" as the subr name.
Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
* gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
gh_equal_p): Use SCM_NFALSEP, instead of testing against
SCM_BOOL_T. Any non-false value is true.
Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
scm_gensym): Added prototypes.
* symbols.c (scm_gensym): New function. This will speed up
certain types of applications (such as macro systems) which
generate lots of symbols.
Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
* unif.c (scm_shap2ra): tighten the checking of the array dimension
specifier, since (2) or (2 . 3) would cause SEGV.
(scm_transpose_array): more argument checking fixes.
Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
* Makefile.in: Regenerated.
Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
* Makefile.in: Regenerated, so it uses "tar", not "gtar".
Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* error.c, error.h (scm_error_callback): Removed (see NEWS).
Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
* regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
<rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
library.)
* ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
scm_array_p, scm_array_rank, scm_array_dimensions,
scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
scm_array_prototype): Added case scm_tc7_wvect.
Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
* errno.h: prototype for scm_strerror.
* error.c (scm_strerror): new procedure.
Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* list.c (scm_list_append_x): Allow non-pair as last argument.
This is consistent with the R4RS append and is probably the
correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
* stime.h: prototype for scm_times.
* stime.c (scm_times): new procedure.
* ioext.c (scm_fseek): if the first argument is a file descriptor
call lseek.
(scm_ftell): if the first argument is a file descriptor call lseek
(sic).
* filesys.h: prototypes for scm_open_fdes, scm_fsync.
* filesys.c (scm_chmod): if the first argument is a file descriptor,
call fchmod.
(scm_chown): if the first argument is a port or file descriptor,
call fchown.
(scm_truncate_file): new procedure.
Add DEFER/ALLOW INTS to a few other procedures.
(scm_fsync): new procedure.
(scm_open_fdes): new procedure.
(scm_open): use scm_open_fdes. If mode isn't specified, 666 will
now be used.
(scm_fcntl): the first argument can now be a file descriptor. The
third argument is now optional.
* posix.c (scm_execl, scm_execlp): make the filename argument
compulsory, since omitting it causes SEGV.
(scm_sync): return unspecified instead of #f.
(scm_execle): new procedure.
(environ_list_to_c): new procedure.
(scm_environ): use environ_list_to_c. disable interrupts.
(scm_convert_exec_args): take pos and subr arguments and
improve error checking.
1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
(scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
argument to SCM_ASSERT. Furthermore, the name of the function
should be passed as first argument when signalling
SCM_WNA. (Thanks to Thomas Morgan)
* gsubr.c (scm_gsubr_apply): From Radey Shouman
<shouman@zianet.com>: "The switch in scm_gsubr_apply that
dispatches on the number of actual args has a default case
reporting an internal error. This is a vestige from a version
that mallocated a SCM vector to hold the arguments. In the
current version this check is too late: if it ever happens we will
have already overstepped the bounds of the array.
Also, the patch [...] adds a check for too many actual arguments."
mdj: Removed check for "internal programming error".
Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* gh_io.c (gh_write): New function.
* gh_eval.c (catch_with_saved_stack): Removed. Replaced by:

gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
scm_internal_stack_catch.
Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
* ioext.h: fix up prototypes.
* ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
Scheme name is now dup->fdes.
(scm_dup_to_fdes): make the second argument optional and
fold in the functionality of scm_primitive_dup.
(scm_primitive_dup): deleted.
Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
* fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
* fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
ultrix are defined. Use setvbuf instead of setbuf.
(scm_setvbuf): new procedure.
(scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
(scm_setfileno): moved from ioext.c.
(scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.

state as nested data while they are printed.
(print_state_fluid, print_state_fluid_num): New variables.
(scm_init_print): Initialize them.
(scm_iprin): If print_state_fluid carries a print_state, use that
instead of creating a new one.
(scm_printer_apply, apply_stub, struct apply_data): New
definitions to help with calling printer functions written in
Scheme.
* print.h (scm_printer_apply): New prototype.
* struct.c (scm_print_struct): Use scm_printer_apply to call the
user defined struct printer.
* dynwind.c (scm_dowinds): Handle fluids on the wind list.
* fluids.h (scm_internal_with_fluids, scm_with_fluids,
scm_swap_fluids, scm_swap_fluids_reverse): New prototypes.
* fluids.c (scm_internal_with_fluids, scm_with_fluids,
scm_swap_fluids, scm_swap_fluids_reverse): New functions.
Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
* fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
SCM_ASSERT: arg comes before pos.
Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
to a list of length zero correctly.

Mon Jul 21 04:03:42 1997 Gary Houston <ghouston@actrix.gen.nz>
* ioext.h: removed scm_duplicate_port prototype.
* ioext.c (scm_primitive_dup2): return the new file descriptor
instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
is convenient.
(scm_fdopen): bug fix: don't try to make port unbuffered until its
stream has been set.
(scm_duplicate_port): deleted, there's now an implementation in
boot-9.scm.
(scm_primitive_dup2): do nothing if newfd == oldfd.
Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>

throw an error if an error other than EBADF occurs.
* filesys.h: scm_close prototype.
* filesys.c (scm_close): new procedure, can close file descriptors
and ports (scsh compatible).
* ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
optional argument.
Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
* fluids.c, fluid.h: New files.

scm_init_fluids to initialize the fluid machine.
(scm_start_stack): Initialize the fluids of the first root with
scm_make_initial_fluids.
* root.h: Added "fluids" member to scm_root_state.

data. (dynl_smob): Use it.
* dynl.c (scm_dynamic_link): Moved allocating of the memory for
the dynamic object data below the linking of the object to avoid
memory leak when the linking code throws an error. Now the code
leaks a whole dynamically linked library when must_malloc throws,
but that should be much less likely.
Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
Changes to compile under gnu-win32, from Marcus Daniels:
* stime.c (tzset): If tzset isn't provided, make it a NOP.

(scm_addr_vector): Likewise.
(scm_init_addr_buffer): Likewise.
(scm_socketpair): Don't include unless socketpair was

scm_misc_error, not SCM_EOF.
* error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
arguments for formatting the error message, not SCM_BOOL_F. I
think this is left over from the (eq? '() #f) days.

DEBUG_EXTENSIONS isn't #defined.
Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>

alloca.lo will be included in @LIBLOBJS@. Something better than
this should be possible.
* Makefile.in: Regenerated.
Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
* simpos.h: prototype for scm_primitive_exit.

After all the Scheme handler function might signal an error too,
and we don't want to lose that.
(cwdr_inner_body): Renamed from cwdr_body.
(cwdr_outer_body): New function, to establish the user's handler,
and pass control to cwdr_inner_body.
(cwdr): Establish the reliable catch-all handler here, and pass

* __scm.h: (SCM_FENCE): New macro: optimizer will not move code
across this. Only works on GCC. Otherwise, we hope for the best.
(SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
the feeling that real thread systems will not need this...
Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
Try to detect when people are using one version of libguile and a
different version of ice-9. People have been skewing things and
sending in bug reports.
* Makefile.am (versiondat.h): New file to generate.
* version.c: #include "versiondat.h", to get version info.
(scm_libguile_config_stamp): New function.
* script.c: #include "version.h".
(scm_compile_switches): Call scm_version to get version number.
* scmconfig.h.in, Makefile.in: Regenerated.
* Makefile.in: Regenerated.
* Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
primitive definitions under their Scheme names.
* Makefile.am (libguile_la_LDFLAGS): Update library version to
1:2. Helps avoid confusion between installed and uninstalled libs.
* scmconfig.h.in: Regenerated. (Needed after June 3 change to
../configure.in.)
* gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
backslash from definition; this should be used like: GDB_INTERFACE;
Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
* ioext.c (scm_duplicate_port): bug fix: don't try to make the
new port unbuffered until its stream has been set.
Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
* ports.h: new prototype.
* ports.c (scm_flush_all_ports): new procedure, scsh compatible.
Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
Make things compile neatly under Sun's C compiler.
* dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
* extchrs.c (xmbtowc): Make the second arg a normal char, not
unsigned, because that's what the ANSI function takes.
* extchrs.h (xmbtowc): Corresponding change to prototype.
* genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
uchars here.
* mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
argument plain char *.
* strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
char.
* tag.c (scm_tag): Remove unreachable statement.
* unif.c (scm_array_to_list): If we want to shift a 1 bit to the
top of the word, it should be unsigned.
* eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
is defined, to avoid warnings; it's only used in the
conflict-checking code. Which might go away anyway.
(SCM_CEVAL): All goto's targeting the `dispatch' label are in
conditionals; put the label definition in an #if too, to stifle
warnings.
* Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
ChangeLog-threads in the distribution.
* Makefile.in: Regenerated.
Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
* guile-snarf.in: Changed regexp to support CPPs that insert
whitespace between lexical tokens (which munges the `%%%' snarf
cookie).
Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
* load.c (scm_init_load_path): Append $(datadir)/guile to
%load-path, so modules do not have to be installed in Guile's
current version directory.
Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
* dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
(scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
call the sysdep functions with deferred ints.
* dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
deferred interrupts and insert SCM_ALLOW_INTS before throwing an
error.
* dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
SCM_UNSPECIFIED.
Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
* scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
* Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
../configure.in.
Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
* eval.c (scm_lookupcar1): New procedure to cope with a race
condition during lookup (when using threads).
(scm_lookupcar): Implement in terms of scm_lookupcar1.
(SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
place.
Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
* regex-posix.c (scm_regexp_exec): Use the `start' argument if
supplied. (Change from Tim Pierce.)
Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
* struct.c (init_struct): Forget to mention this in the "Wed Jun 4
23:47:01 1997" changelog: Slots are now initialized with `#f' by
default and not `()'. `#f' is the canonical non-value in Scheme,
right?
Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
* struct.c (struct_printer): New variable that holds a handle on
the Scheme variable *struct-printer*. This variable can be set by
Scheme code to override the printing of structures.
(scm_print_struct): If struct_printer is set, call it. If it is
not set, or returns #f, print the structure in the old fashion.
Include "eval.h" for scm_apply.
Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
* struct.c (scm_struct_ref, scm_struct_set_x): Use
scm_struct_i_n_words to get the number of fields, not
-scm_struct_n_extra_words.
On the route to fancier struct printing:
* struct.c (scm_print_struct): New function to print a structure.
Include "genio.h" to support it. This function doesn't do
anything interesting right now, but I think it should be here
anyway.
* struct.h: Include "print.h" and add prototype for
scm_print_struct.
* print.c (scm_iprin1): Call scm_print_struct instead of trying to
print structures ourself.
Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
* scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
before applying the handler in case it doesn't return.
Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
* scmsigs.h, async.h: updated.
* _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
loop.
* posix.c (scm_uname): interpret only negative values as an error.
Solaris normally returns a positive value.
* script.c (scm_compile_shell_switches): if we are not going into
an interactive repl, set scm_mask_ints to zero so that asyncs can
run.
* simpos.c (scm_system): don't ignore/unignore signals around
the "system" call.
* posix.c (scm_open_pipe): don't ignore/unignore signals around
the "popen" call.
* init.c (scm_boot_guile_1): don't call scm_init_signals, it's
done in boot-9.scm instead.
* scmsigs.c, async.c: Major rewriting of signal handling code.
(scm_sigaction): new procedure.
(scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
timing.
(scm_raise): return unspecified, throw error on failure.
Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
* regex-posix.c (scm_init_regex_posix): Register the "regex"
feature, to help boot-9.scm decide whether to import the regex
module.
Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
* eval.c: Include scmconfig.h at the beginning of the file so that
HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
pointing this out.
* regex-posix.c: #include "_scm.h" before conditionally #including
<regex.h>; the former defines HAVE_REGCOMP.
* regex-posix.c: #include <regex.h> conditionally, so the file is
CPP'able (for dependency scanning) even on systems that don't have
a <regex.h> header.
Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
Add new R4RS-compliant syntax for keywords.
* read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
regardless of the setting of the `keywords' read option.
* kw.c (prin_kw): Print keywords using the `#:' syntax, so they
can be re-read no matter what the setting of the `keywords' read
option.
Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
Add support for POSIX regular expressions.
* regex-posix.c, regex-posix.h: New files. (Some code
is taken liberally from rx/rgx.c in the old Guile dist.)
* init.c: Include regex-posix.h.
(scm_boot_guile_1): Call scm_init_regex_posix.
* Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
Add regex-posix.[ch] sources.
* Makefile.in: Regenerated.
* scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
to do this automatically? It didn't for me, bleh.)
Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
* fports.c (print_pipe_port): New function.
(scm_fptob): Use print_pipe_port instead of scm_prinport; the
latter doesn't even take the right arguments.
* Makefile.am: Increment shared lib revision number. I think
sometimes the uninstalled Guile finds the installed shared lib;
Gord says doing this might help. As things turned out, I can't
say whether it does.
* Makefile.in: Regenerated.
* gh_init.c (gh_enter): Cast c_main_prog to a void * before
passing it as the closure argument to scm_boot_guile. (Bill
Janssen)
* ports.c (print_void_port, putc_void_port, puts_void_port,
write_void_port, flush_void_port, getc_void_port, close_void_port,
noop0): Use ANSI prototypes instead of K&R declarations, so the
initialization of void_port_ptob gets aggressively type-checked.
Fix arguments of print_void_port and write_void_port. (Bill
Janssen)

Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
* script.c (scm_find_executable): Use prototype-style definition
here; apparently it's not quite right to have const in a prototype
and then use a K&R declaration. I wonder if stuff like this will
go away if we compile with -Wrequire-prototypes, or whatever that
is... (Bernard URBAN)
* scmhob.h: New text from Bernard URBAN.
Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
* script.c: Don't #define const on hpux. Configure takes care of
this. (Thanks to Larry Schwimmer.)
* script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
decide whether to #include <unistd.h>, instead of listing a bunch
of systems. Don't #include stdio twice. Removed dyked-out
definition of scm_find_impl_file.
Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
* Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
library version info to 1:0.
* Makefile.in: Regenerated.
* backtrace.c, backtrace.h, debug.c, debug.h, eq.c,
gdb_interface.h, gdbint.c, gdbint.h, gh_data.c, gh_init.c,
gh_io.c, gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c,

significantly in 1997, but only had copyright years for 1996.
Also, change name of copyright holder on some from Mikael
Djurfeldt to Free Software Foundation; he has signed papers
assigning the changes to the FSF.
* script.c (scm_shell_usage): Pass FATAL to exit. There's no
reason not to give the user the option.
* net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
Return #f on end-of-file when scanning table (i.e. when called
with no arguments). Try to catch errors, when we can.
* posix.c (scm_getgrgid, scm_getpwuid): Same.
* script.h (scm_shell_usage, scm_compile_shell_switches): New
external declarations. These are useful.
Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
* posix.c: don't include <sys/select.h> or define macros for
select, since they were not used in this file.
* filesys.c (scm_select): make the fifth parameter microseconds,
not milliseconds. let the fourth parameter be either a real value
or an integer or #f. The first, second and third arguments can
now be vectors: the type of the corresponding return set will be
the same.
(set_element, get_element): new static procedures.
Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
* strports.c (scm_eval_string): New function.
(scm_eval_0str): Trivially re-implemented in terms of
scm_eval_string.
* strports.h (scm_eval_string): New extern decl.
* net_db.c (h_errno): Add extern decl for this.
* fports.c (local_pclose): New function.
(scm_pipob): Use it in the initializer here.
From Tim Pierce:
* net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
Use a meaningful error message when signalling an error. For
this, scm_gethost must check h_errno rather than errno.
Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
* Makefile.in: Regenerated, using automake-1.1p.
Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
* socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
not SCM_UNSPECIFIED.
* script.c (scm_compile_shell_switches): don't append (quit) if
interactive.
(scm_shell): call scm_exit_status and exit on the result of the
evaluation.
Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
Ensure that shared substrings are handled properly when passed to
a system call or other foreign function. Many thanks to Tim
Pierce!
* symbols.h (SCM_COERCE_SUBSTR): new macro.
* filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
scm_strftime), vports.c (scm_make_soft_port), backtrace.c
(scm_display_error_message): use RO macros when strings may be RO.
* error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
scm_strftime), vports.c (scm_make_soft_port): use
SCM_COERCE_SUBSTR to make sure shared substrings are
null-terminated.
Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
* error.c (scm_error): Add newline to error message.
* init.c (scm_init_standard_ports): Doc fix.
Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
* dynl-shl.c: Completely replaced with new code from Bernard
URBAN.

(scm_compile_shell_switches): Use it.
Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
* filesys.c (scm_input_waiting_p): add missing third argument to
scm_misc_error.
* stime.c (scm_localtime): copy the result of localtime before
calling gmtime in case they share a buffer.
(scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
nor HAVE_TZNAME.
Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
* eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
* Makefile.am (check-local): New target, which causes 'make check'
to run gh_test_c and gh_test_repl, with some trivial input.
* Makefile.in: Rgnrtd.
Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
* dynl.c (print_dynl_obj): Indicate whether the dynamic object has
been unlinked.
Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
* async.c (scm_sys_tick_async_thunk): commented out. I'm not
sure how this was supposed to work.
(scm_async_click): don't send SCM_TICK_SIGNAL.
(scm_init_async): don't initialize %tick-thunk.
* the following change doesn't affect the Scheme interface:
gc-thunk is called at the end of garbage collection. however it's
no longer implemented by pretending it's a signal.
* gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
system async corresponding to scm_gc_thunk.
* async.h: declare scm_gc_async.
* async.c (scm_sys_gc_async_thunk): apply the thunk named by
gc-thunk directly, instead of going through a signal handler.
(scm_gc_async): new variable, points to the GC system-async.
(scm_init_async): save the GC async as scm_gc_async instead
of using system_signal_asyncs.
(scm_gc_vcell): new variable, stores the gc-thunk vcell.
Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
* Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
Don't screw up if we're interrupted.
* Makefile.in: Regeneradet.
Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
* aclocal.m4: Removed; unnecessary, given changes of Apr 24.
* Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
we're not using AM_INIT_GUILE_MODULE any more.
* Makefile.in: Reneregated.
Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
Functions for finding variable bindings, grace <20> Tim Pierce.
* gh_data.c (gh_lookup, gh_module_lookup): New functions.
* gh.h (gh_lookup, gh_module_lookup): New prototypes.
Get 'make dist' to work again.
* Makefile.am (EXTRA_DIST): Remove PLUGIN files.
* Makefile.in: Regenerated, like a surry without a fringe on top.
Changes for reduced Guile distribution: one configure script,
no plugins.
* configure.in, configure: Removed.
* acconfig.h, acinclude.m4: Moved to parent directory, where the
real configure script lives.
* Makefile.in, scmconfig.h.in: Regenerated.
* init.c: #include "script.h", to get prototype for script.c's
init function.
Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
* gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
scm_must_malloc, not raw malloc.
* script.c (scm_compile_shell_switches): Dyke out debugging output
code.
Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
* eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
* stime.c: include both <sys/times.h> and <sys/timeb.h> if the
system has them. Hope this is safe. Previously
sys/timeb.h was included if HAVE_FTIME was defined or if
HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
* ioext.c (scm_setfileno): add missing third argument to
scm_misc_error call.
Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
* eq.c (scm_equal_p): Correctly compare strings of different
varieties. (Thanks to Tim Pierce.)
Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
* read.c (skip_scsh_block_comment): SCSH says the !# that ends a
#! block comment must occur on a line all by itself.
Move most of the guts of shell command processing into libguile,
so guile.c can be very small (and eventuallly auto-generated. (I
mean, generated mechanically, not self-generated. Hmm.))
* guile.c, script.c, script.h: New source files.
* init.c (scm_boot_guile_1): Call scm_init_script.
* libguile.h: #include "script.h".
* Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
targets, for new executable.
(libguile_la_SOURCES): Mention script.c.
(modinclude_HEADERS): Add script.h.
* configure.in: Always check for -lm, -lsocket, -lnsl, whether or
not dynamic linking is enabled. This is because we're generating
executables now. Move CY_AC_WITH_THREADS call after those, so the
values of cy_cv_threads_libs captures the libs chosen above.
* Makefile.in, configure, aclocal.m4: Regenerated.
* Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
We don't maintain this interface any more, and it just confuses
people.
* alloca.c: #include <scmconfig.h>, not <config.h>.
* Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
it'll get included in disties.
Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
* gscm.c, gscm.h: These aren't supported any more, and shouldn't
be distributed, because they confuse people.
* Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
* configure.in: check for presence of gethostent (not present on
OpenBSD by default).

Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
* backtrace.c (scm_backtrace): Split message string across
newlines properly. GCC is more tolerant of this than other
compilers.
Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
Merge threads directory into libguile.

* fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
currently used, but brought along for information's sake.
* ChangeLog-threads: log from old 'threads' directory.
* Makefile.in, configure: Rebuilt.
Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
* stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
lt->tm_zone.
Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>

gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
New variables, describing how to build the gh test programs.
* configure.in: Check for -lm, -lsocket, -lnsl; we need this to
build the test programs, and we probably should have been linking
libguile.la against them all along, to support AIX shared libs.
Add cflags for threads to CFLAGS; add libs for threads to new
variable THREAD_LIBS, used in Makefile.am.
* ChangeLog-gh: log from old `gh' subdirectory.
* Makefile.in, configure, scmconfig.h.in: Rebuilt.
Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
* acconfig.h: Undo change of Apr 9; including the definition of
PACKAGE in the guile headers conflicts with applications' own
definitions.
* scmconfig.h.in: Regenerated.
Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
* filesys.c (scm_fcntl): New function from Roland McGrath.

Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
* filesys.c (S_ISSOCK): Define this if it's missing, but we do
have S_IFSOCK. This is the case under Ultrix.
* posix.c (scm_status_exit_val, scm_status_exit_val,
scm_status_term_sig, scm_status_stop_sig): Modified to work with
Ultrix versions of WIFSTOPPED, etc., which assume that their
arguments are lvalues (hmm).
Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
* eval.c: Doc fixes.
* throw.c: Doc fixes; rearranged.

* acconfig.h: Added entry for PACKAGE.
* scmconfig.h.in: Regenerated.
Changes to work with automake-1.1n, which has better libtool support.
* Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
difference here?)
(libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
readability.
* Makefile.in: Rebuild.
Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
* stime.c (scm_mktime): take an optional zone argument.

(scm_strftime): don't call mktime before strftime. Use
filltime for return value.
(filltime): convert NULL zname to #f.
(scm_strptime): return a count of characters consumed, not
the remaining string.
Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
* stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
(scm_mktime): likewise.
Declare *tzname[].
Uncomment localtime and mktime.
* configure.in: add AC_STRUCT_TIMEZONE.
Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
* stime.c (scm_init_stime): don't define ticks/sec.
(scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
return value problem and is still portable.)
Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
* cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
* cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
* Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
cpp_err_symbols.c): Corresponding changes.
* Makefile.in: Regenerated.
Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
* posix.c (scm_putenv): don't check HAVE_PUTENV.
* Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
* configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
* putenv.c: new file, from sh-utils 1.12.
* posix.c (scm_environ): use malloc in place of scm_must_malloc
since allocation isn't for Scheme objects.
(scm_putenv): copy strings before placing in the environment.
* stime.c (scm_current_time): throw an error if time returns -1,
instead of returning #f.
(scm_get_internal_real_time, scm_get_internal_real_time): use
scm_long2num for return value instead of SCM_MAKINUM.
* stime.h: prototypes updated.
* stime.c (scm_time_in_msec): apparently unused, deleted.
Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
* configure.in: check for gettimeofday.
* stime.c (scm_time_plus_ticks): new procedure, an scsh interface
which may be more usefully portable than a gettimeofday interface.
Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
* Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
cpp_err_signals.

define them in boot-9.scm
Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
* ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
wan't defined. Don't include fd.h.
* Previously fd.h was regenerated whenever configure was run,
forcing a couple of files to be recompiled.
* fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
* configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
Check for _fileno as well as _file.
Don't output fd.h.
* ioext.c: don't fd.h.
* acconfig.h: remove duplicate HAVE_FD_SETTER and change the
other to FD_SETTER.
* Change the stratigy for getting information about errno
(and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
generating lists of symbols during the build process, which will
not always work, include comprehensive lists in the distribution.
To help keep the lists up to date, the "check_signals" and
"check_errnos" make targets can be used.
* configure.in: don't check for a command to extract errno codes.
* Makefile.am: update file lists, remove errnos.list and errnos.c
targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
check_errnos targets.
(CLEANFILES): remove errnos.c and errnos.list, add
cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new

* error.c (scm_init_error): #include cpp_err_symbols instead of
errnos.c.
* posix.c (scm_init_posix): don't intern signal symbols. #include
cpp_sig_symbols.c.
Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
* strop.c (scm_i_index): allow the lower bound to be equal to the
length of the string, so a null string doesn't always give an error.
* posix.h: new prototypes.
* posix.c (scm_status_exit_val, scm_status_term_sig,
scm_status_stop_sig): new functions, as in scsh. They break down
process status values as returned by waitpid.
Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
* net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
configure doesn't know about it.
Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
* snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
which defines C variables with global linkage.
Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
zero arg subrs.
Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
* eval.c (safe_setjmp): Temporarily use old setjmp until someone
has time to check why this doesn't work well with continuations.
Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
* Fix shell syntax error; some shells won't tolerate
multiple "fi" statements on a single line. (Thanks to Fred Fish.)
Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
* posix.c (scm_uname): throw an error if uname fails instead
of returning errno.
* error.h (scm_errno, scm_perror): obsolete prototypes removed.
* error.c (err_head, scm_errno, scm_perror): obsolete procedures
removed.
* async.c (scm_ints_disabled): definition moved from error.c.
Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* acconfig.h: Removed PACKAGE.
* scmconfig.h.in: Regenerated.
* snarf.h: g++ says it's non-portable not to specify the first
argument in a varargs declaration. I introduced the first
argument by using preprocessor conditionals.
Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
* ioext.c (scm_read_delimited_x): use RO string macros for delims.
(scm_freopen): use RO string macros for filename and modes.
(scm_duplicate_port, scm_fdopen): use RO string macros for modes.
* posix.c (scm_getgrgid): simplify conversion of name to C string.
(scm_mknod): use RO string macros for path.
* socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
* net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
use SCM_ROSTRINGP and SCM_ROCHARS.
Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
a scm_tc7_byvect.
* ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
support for byte vectors.
* print.c (scm_iprin1): Limit number of vector elements printed
according to pstate->length.
Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
* backtrace.c (scm_display_error_message): don't segv if message
is an immediate.
* error.h: prototype for scm_error_scm.
* error.c (scm_error_scm): new procedure, reimplements scm-error
in C and uses scm_error.
Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
* read.c (scm_read_hash_extend): make scm_read_hash_procedures a
pointer to the Scheme variable read-hash-procedures and intern it
in scm_init_read. Modify scm_read_hash_extend and
scm_get_hash_procedure to use the pointer.
Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
* read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
(SCM_KEYWORD_STYLE): defined.
* read.c (scm_read_opts): add a keywords option. This isn't a
boolean option, in case someone wants to add support for DSSSL
keywords too.
Setup scm_keyword_prefix symbol.
(scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
set to 'prefix.
I've left keyword support disabled by default, since it doesn't
seem to break the module system and it gives R4RS standard behaviour.
It can be reactivated with (read-set! keywords 'prefix).
Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
before constructing arbiter.
* eval.c (scm_m_define): Bugfix: Check that the object is a
closure before setting the procedure property!
* ports.h: Removed prototype for scm_ungetc_char_ready_p.
* ports.c: Removed `ungetc-char-ready?'.
Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
* read.c (scm_init_read): intitialise scm_read_hash_procedures
(idea from Mikael: make it a pair so scm_permanent object only
called once.)
(scm_read_hash_extend): don't call scm_permanent_object.
(ideas from Mikael): if chr is already in the list, replace its
procedure instead of appending it again. If proc is #f, remove
it from the list.
(scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
* strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
* gdbint.c (gdb_read): update scm_lreadr usage.
* load.h: update prototypes.
* load.c (scm_primitive_load, scm_read_and_eval_x,
scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
* read.h: add prototype for scm_read_hash_extend. Change args for
other prototypes.
* read.c (scm_read_hash_procedures): new variable.
(scm_read_hash_extend): new procedure.
(scm_get_hash_procedure): new procedure.
(scm_lreadr): use scm_get_hash_procedure instead of an argument
for extended # processing.
(scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
scm_read_token): remove case_i, sharp arguments. Change callers.
Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
* read.h (SCM_N_READ_OPTIONS): increase to 3.
(SCM_CASE_INSENSITIVE_P): define.
* read.c: add case-insensitive option to scm_read_opts.
(scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
to determine whether to convert symbol case.
(default_case_i): definition removed.
* read.c (scm_read_token): if case_i, downcase ic before doing
anything with it.
Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* configure.in: Added configuration option `guile-debug'.
Configure with --enable-guile-debug if you want a bunch of extra
functions used for debugging when developing Guile.
* acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
* procs.c (make-cclo): New undocumented debugging procedure: Make
compiled closure with internal procedure PROC and length LENGTH.
Only compiled if GUILE_DEBUG is defined.
* debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
* print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
* ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
* eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
with 3 or more args internally to the evaluator.
Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* eval.c (SCM_CEVAL): Added code sections for handling of asubrs
with 3 or more args internally to the evaluator. This is mainly
because we don't want to pass entry and exit points of the
debug support twice, but it also seems to increase the speed of
the evaluator for such calls (e. g. (+ 1 2 3)).
* backtrace.c (scm_display_application): New procedure:
display-application; Set fancy printing parameters individually
for different types of display (backtrace, error, application).
(These should of course be customizable!)
* debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
clear the CHECK-flags.
Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
from pairs with a GLOC in the car.
* symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
otherwise `symbol-hash' will behave badly.
(scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
we get segmentation fault!
* symbols.c: Added #include "weaks.h". New functions:
`builtin-bindings' and `builtin-weak-bindings'. (These will be
moved to an extraneous library when we split libguile.)
Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* filesys.c (scm_stat): stat now takes fport arguments too as
documented in the manual.
Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* debug.c (scm_single_step): Bugfix: Call continuation with
scm_call_continuation instead of throwing to it.
Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
* ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
argument wasn't declared to be optional.
Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* stime.c (scm_init_stime): Add feature "current-time".
Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
* throw.h: prototype for scm_exit_status.
* throw.c (scm_handle_by_message): if a 'quit is caught, use its
args to derive an exit status. Allows (quit) to work from a
script.
(scm_exit_status): new function.
#include "eq.h".
Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* eval.c (scm_deval): Removed some old code.
(ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
with the others.
(ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
exit-frame traps.
* symbols.c (msymbolize): Bugfix: Must initialize property list to
SCM_EOL.
* procs.c: Introduce the existent C function scm_thunk_p at the
Scheme level as well.
Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* symbols.c, symbols.h (scm_symbol_value0): New function. Can be
used from C to easily lookup the value of a symbol in the current
module.
Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* unif.c (scm_init_unif): Added #include "unif.x". (There are two
scm_init_unif in this file. This will also fix a previous problem
with guile-snarf.)
* configure.in: Added AM_MAINTAINER_MODE
Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
avoid warnings.
Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
* Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
source files that are not always included in libguile but should
have their dependencies calculated by automake. This variable is
recognized by automake, no further magic is needed.
(libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
to deal exclusively with *.lo files, as it seems. The *.o files
are built automatically when the corresponding *.lo file gets
built.
Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
* list.h (scm_list_cdr_ref): Delete prototype; function no longer
exists.
Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
* unif.c (scm_array_set_x): minor change to argument error checking.
Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
* Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
They should only be included in the library at configure.in's
discretion.
(libguile_la_LDADD): Include the appropriate .lo files here.
(libguile_la_DEPENDENCIES): List the corresponding .o files here,
so we know when to build them (and their .lo bretheren).
* configure.in (LIBLOBJS): New substituted variable. We let
configure decide which .o files to include in LIBOBJS, and then
put the corresponding list of .lo files in LIBLOBJS. The latter
is what we pass to libtool.
* Makefile.in, configure: regenerated.
Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
* symbols.c (scm_sysintern0): New function. Contains the core of
old scm_sysintern but doesn't take a second value argument.
(scm_sysintern): Now uses scm_sysintern0.
(scm_sysintern_no_module_lookup): Renamed to
scm_sysintern0_no_module_lookup and doesn't take a second value
argument any longer.
* symbols.h (scm_sysintern0: Added declaration.
* options.c (scm_init_opts): Use scm_sysintern0 instead of
scm_sysintern when interning option keys. Otherwise we risk
destroying the values of already interned variables.
* symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
scheme-level boolean (use SCM_NFALSEP).
* backtrace.c (scm_init_backtrace): Make Scheme-level variable
`the-last-stack'.
(scm_backtrace): New function. (C version of old function from
boot-9.scm) Motivation: Make it possible to display backtraces
without depending on boot-9.scm. (I'm uncertain if this
motivation is good enough...)
* root.h (scm_root_state): Add member the_last_stack_var.
(scm_the_stack_var): Defined to scm_root->the_last_stack_var.
* root.c (mark_root): Mark scm_the_last_stack_var.
* init.c (scm_start_stack): Initialize scm_the_last_stack_var to
SCM_BOOL_F.
Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
* throw.c (mark_lazy_catch, free_lazy_catch): Removed.
1. mark_lazy_catch didn't mark the smob.
2. Both functions above have standard variants:
(lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
free_lazy_catch --> scm_free0.
Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
* throw.c (scm_internal_lazy_catch): New function.
(scm_lazy_catch): Rewritten to use it.
(scm_ithrow): Handle the new lazy catch representation.
Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
that doesn't have a jmpbuf is a lazy catch clause.
(tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
free_lazy_catch, print_lazy_catch, lazy_catch_funs,
make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
smob.
(scm_init_throw): Register the new lazy-catch smob type.
* throw.h (scm_internal_lazy_catch): decl for new function.
* throw.c (scm_internal_catch): Doc fixes.
* alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
configure.in. Including this might cause problems if applications
that link against libguile include their own copies of alloca, but
if they're using autoconf, they should be adding libguile to LIBS
before calling AC_FUNC_ALLOCA anyway, in which case they'll find
the copy in libguile, and things will be okay. (I think.)
Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
* strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
unif.c.
strop.h: move prototypes too.
Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
* posix.c (scm_init_posix): don't intern EINTR since it's now done
elsewhere.
* ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
etc. I deleted them from filesys.c long ago, but didn't
notice they were here too (although ineffective since
sys/stat.h wasn't included).
Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
* eval.c: Don't define alloca in GCC case. gcc will automatically
use __builtin_alloca if appropriate.
Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
* eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
(SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
that values of automatic variables are preserved. See comments
for safe_setjmp for details.
Change from Thomas Morgan:
* variable.c: Include eq.h.
(var_equal): New function.
(variable_smob): Use var_equal as the discriminator for variables.
* throw.c (s_throw): Remove extraneous declaration.
* configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
* eval.c: Add necessary CPP cruft to support that.
* configure, Makefile.in, scmconfig.h.in: regenerated.
Change from Thomas Morgan:
* procprop.c (scm_procedure_properties): Convert the Scheme
boolean returned by scm_procedure_p into a C boolean before using
it as a condition for SCM_ASSERT.
(scm_procedure_property): Likewise.
* simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
indications of Unixness.
* stime.c: Same.
Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
* net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
* read.c (scm_lreadr): use scm_misc_error to improve one of the
"unknown # object" error messages.
* strop.c (scm_i_index, scm_i_rindex): combine into one procedure
(scm_i_index) and declare it static. Add a 'direction' argument
to indicate what way the search should go.
(scm_i_index): throw out-of-range error instead of wrong-type-arg
if indices are bad.
(scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
strop.h: remove scm_i_index, scm_i_rindex prototypes.
Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
* ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
* posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
to avoid clash with various scsh forks.
Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
The following two changes (ramap.c, throw.c) are motivated by the
apparent unportability of forward declarations of static arrays of
the form `static foo bar[];'.
* ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
(ra_rpsubrs, ra_asubrs): Moved to the top of array code.
* throw.c (scm_throw): Moved above scm_ithrow.
* options.h: Removed the extern declarations of scm_yes_sym and
scm_no_sym since these are static.
Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
* ports.c: add SCM_PROC declarations for pt-size and pt-member.
* Makefile.am: remove AWK=@AWK@.
Add a rule for generating errnos.list.
(CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
* configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
don't extract errnos, just set a variable (avoids the
need to recompile error.c just because configure is run.)
* unif.h: update prototypes.
* unif.c (scm_uniform_array_read,write): change the offset and
length arguments to start and end, for consistency.
* __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
* ioext.h: update prototypes.
* ioext.c (scm_read_delimited_x): replaces scm_read_line and
scm_read_line_x, it's a more general procedure using an
interface from scsh. read-line and read-line! are now defined
in boot-9.scm.
Note that the new read-line trims the terminator
by default, previously it was appended to the returned string. An
optional argument specifies how to process the terminator (scsh
compatible). For the old behaviour: (read-line port 'concat).
scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
returns a pair, but is converted to multiple values if the scsh
module is loaded.
socket.h: update prototypes.
* socket.c (scm_recvfrom): for consistency with other procedures,
take start and end as separate optional arguments.
(scm_recv, scm_recvfrom): don't allow the second argument
to be a size, only a buffer. Change the scheme names to
recv! and recvfrom!. Don't return the buffer.
* ioext.h, posix.h: move prototypes too.
* ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
moved back from posix.c to ioext.c. Also move #includes of "genio.h"
"read.h" and "unif.h".
* ioext.c: include "chars.h"
Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
* dynl.c: The dynamic linking and module registration functions
are now defined even when dynamic linking is not available for the
host system. Some of their functionality can be done without
dynamic linking; when it's really needed, they throw errors.
Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
* configure.in: Only define DYNAMIC_LINKING when one of the system
dependent functions is detected.
* dynl.c (scm_dynamic_func): New function to get the address of a
function in a dynamic object.
(scm_dynamic_call, scm_dynamic_args_call): Accept the values
produced by scm_dynamic_func as the thing to call.
Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
* dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
(scm_register_module_xxx, scm_registered_modules,
scm_clear_registered_modules): New functions.
Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
* symbols.c (scm_sysintern): Renamed to
scm_sysintern_no_module_lookup.
(scm_sysintern): New function to take the place of the old
scm_sysintern. It uses the current toplevel lookup closure to give
the symbol its value. This is a temporary hack to put packages
like gtcltk into their own module.
(scm_can_use_top_level_lookup_closure_var): New variable to tell
us whether `scm_top_level_lookup_closure_var' has been initialized
and is usable.
* eval.c (scm_init_eval): Set it.
Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
* fports.c (scm_open_file): pass errno to scm_syserror_msg.
* filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
SCM_FD.
* filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
scm_syserror_msg.
(scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
scm_sys_dup): deleted: FD capability will be added to other
procedures.
Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
scm_fd_free, fd_smob, scm_intern_fd.
(scm_open): renamed from scm_sys_open. Return a port instead of
an FD object. Make the mode argument optional.
(scm_sys_create): deleted, it's just a special case of open.
(scm_init_filesys): move interning of constants O_CREAT etc.,
here (were previously using SCM_CONST_LONG macro).
Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
don't newsmob fd.
(numerous _sys_ procedures): remove gratuitous _sys_ from names.
include "fports.h" and <stdio.h>
(scm_stat, scm_select): don't support FD objects.
* error.h: adjust scm_syserror_msg prototype.
* error.c (scm_syserror_msg): take an extra argument for errno.
Using the global value didn't always work, since it could be
reset by procedure calls in the message or args arguments.
* fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
I don't understand why the check was there (and what about the
ultrix check?)
* strop.c (scm_string_copy): allow shared substrings to be copied.
* unif.h: corresponding change to prototypes.
* unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
recognize two new optional arguments: offset and length. Allow
the port argument to be an integer (file descriptor, for scsh).
Include <unistd.h> for "read" prototype.
Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
* socket.c: don't include filesys.h.
Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
* Makefile.am: add AWK=@AWK@ (?)
* Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
errnos_get.c.
Add a rule to generate errnos.c from errnos.
* error.c (scm_init_error): include errnos.c.
* errnos_cnvt.awk: new file, converts the list of errno codes to
C expressions.
* errnos_get.c: new file.
* errnos.default: new file, contains errnos to try if they can't
be extracted from errno.h.
* configure.in: if using GCC, try and extract errno codes from
errno.h.
Added AC_PROG_AWK.
Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
* configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
* Makefile.am: Made libguile into a libtool library.
* PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
Set libtool_libs to indicate that libguile is a libtool library.
See guile/ChangeLog for details.
* .cvsignore: ignore "*.lo", the libtool library objects.
Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
* net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
use htons in getservbyport argument.
Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
* ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
* smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
duplicate.
* objprop.c (scm_object_property): No need to take the CDR of the
value returned by scm_object_properties, since Aug 20 change.
* configure.in: When checking for struct linger, #include
<sys/types.h> as well as <sys/socket.h>. I've never known
<sys/types.h> to cause any portability problems, and Solaris's
<sys/socket.h> needs it.
* configure: Rebuilt.
I think the Sun compiler has chosen a perverse way to interpret
ANSI declarations combined with K&R definitions. We'll
appease it a little bit. But when it invades France, we fight.
* print.c (scm_iprlist): Change 'tlr' argument to an int.
* print.h (scm_iprlist): Here too.
* numbers.c (scm_divbigdig): Change definition to match
declaration in numbers.h.
* unif.c (scm_makflo): Change definition to match declaration in
unif.h.
* init.c (scm_boot_guile): Don't return the value of
scm_boot_guile_1. This function doesn't return a value;
scm_boot_guile_1 doesn't return a value (or return at all).
* eval.c (unmemocopy): Add a semicolon to appease the Sun
compiler.
* simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
compile. I have a feeling this function is a bad idea anyway ---
one should always test for features, not systems.
* smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
semicolons. Only pure luck kept this from being noticed earlier.
Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
* socket.c (scm_recvfrom): Added missing semicolon.
Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
* socket.c (scm_recvfrom): allow buff_or_size to be a list containing
the buffer and start and end positions for scsh networking
implementation.
Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
* configure.in: Revert previous change to this file; the problem
is due to transient automake weirdness.
* configure: Rebuilt.
* Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
PLUGIN/guile.libs. configure generates the latter from the former.
* Makefile.in: Rebuilt.
* configure.in: Call AM_PROG_INSTALL; the automake manual says we
need this if we install scripts, like guile-snarf.
* configure: Rebuilt.
Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
* Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
* socket.c (scm_addr_vector): fix faulty scm_listify.
Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
* read.c (scm_lreadr): Encountering EOF after skipping a SCSH
style block comment is no longer considered an error.
Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
* PLUGIN/guile.libs.in: New file.
* PLUGIN/guile.libs: Removed from repository.
* configure.in: Create PLUGIN/guile.libs from
PLUGIN/guile.libs.in. This is for including additonal libraries
needed for dynamic linking.
* Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
instead of PLUGIN/guile.libs.
* Makefile.am: Added explicit dependency "dynl.o: dynl.x".
Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
* list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
occurrences of the given element from the list, not just the
first. This is how the Emacs Lisp functions behave, how the
analogous Common Lisp functions behave, and (I believe) how the
older Maclisp functions worked. I realize that this change may
break code, but it seemed better to break it before the Guile
release than after.
* gc.c (scm_protect_object, scm_unprotect_object): New functions.
Their prototypes were already present in gc.h, but they weren't
implemented.
(scm_init_storage): Initialize scm_protects.
* root.c (scm_protects): New element of scm_sys_protects.
* net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
* libguile.h: Added #include "libguile/net_db.h".
* libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
30 change. That file is only meant for communication between the
configuration process and load.c. If code linked against libguile
wants to get at the paths mentioned in libpath.h, it can call
functions declared in load.h.
Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* libguile.h: Removed #include "libguile/fdsocket.h"
* net_db.c: Added #include <sys/socket.h>.
Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
* filesys.c (scm_input_waiting_p): use select in preference to
FIONREAD, since the latter doesn't detect EOF.
Throw error if neither select nor FIONREAD available.
* socket.c (scm_connect): take a port, not a fd object.
(scm_fill_sockaddr): throw an error if fam is not recognised.
(scm_bind): use scm_fill_sockaddr.
(scm_listen): take a port, not a fd object.
(scm_accept): take and return a port. return #f in the car if
address can't be got
(scm_sock_fd_to_port): new procedure.
(scm_socket): use scm_sock_fd_to_port.
(scm_addr_vector): throw error if unrecognised address type.
take an extra argument with the calling procedure name.
(scm_getsockname): take a port. return #f if address can't be got.
(scm_getpeername): take a port. return #f if address can't be got.
(scm_recvfrom): take a port. return #f for address component if can't
be got.
(scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
* throw.c (scm_internal_catch): Make body funcs and handler funcs
use separate data pointers, to allow them to be designed
independently and reused.
(scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
Renamed from catch_body, catch_handler, and uncaught_throw; made
generically useful.
(struct scm_catch_body_data): Renamed from catch_body_data; moved
to throw.h.
(scm_catch): Use the above.
(scm_throw): Don't bother printing a message for an uncaught
throw; we establish a default handler in init.
* throw.h (scm_internal_catch): Prototype updated.
(scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
decls.
(struct scm_body_thunk_data): New structure, used as data
argument to scm_body_thunk.
* init.c (struct main_func_closure): New structure, packaging up
the data to pass to the user's main function.
(scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
(scm_boot_guile_1): Pass it through to invoke_main_func. Use
scm_internal_catch to establish a catch-all handler, using
scm_handle_by_message. This replaces the special-case code in
scm_throw.
(invoke_main_func): Body function for scm_internal_catch; invoke
the user's main function, using the main_func_closure pointer to
decide what to pass it.
* root.c (struct cwdr_body_data): Remove handler_proc member.
(cwdr): Use scm_handle_by_proc instead of cwdr_handler.
(cwdr_handler): Removed.
Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
* socket.h (SCM_P): update bind prototype.
* socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
include "feature.h".
(scm_socket): return a port, not a file descriptor object.
include "fports.h" and <unistd.h>
(scm_bind): take a port, not a file descriptor object.
take an extra argument for address args.
* net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
INADDR_NONE, INADDR_LOOPBACK.
Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
* init.c: include net_db.h and not fdsocket.h.
(scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
* Makefile.am: corresponding changes.
* socket.h: renamed from fdsocket.h, fix names.
* net_db.h: renamed from socket.h, fix names.
* socket.c: renamed from fdsocket.c.
remove _sys from procedure names.
(scm_init_socket): rename from scm_init_fdsocket. include socket.x.
add "socket" to features list.
* net_db.c: renamed from socket.c.
remove _sys from procedure names.
(scm_init_net_db): rename from scm_init_socket. include net_db.x.
add "net-db" to features list.
include "net_db.h". don't include <sys/socket.h> or
<sys/un.h>.
Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* tags.h (scm_tags): Removed comma at end of last enumerator.
Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
Don't use GCC extensions to allocate space for debugging frames.
(Here he goes again! Why do we put up with this?!)
* debug.h (scm_debug_frame): Make the 'vect' member a pointer to
an scm_debug_info structure, not an in-line array of them. Add
'info' member, to say how many vect elements we've used, for eval
frames.
* eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
a new variable debug_info_end to mark the end of vect, instead of
the address of the 'info' pointer itself.
[DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
&debug to scm_debug_frame *; debug is a real scm_debug_frame now.
(SCM_APPLY): Explicitly allocate space for debug.vect.
* debug.c (scm_m_start_stack): Same, for vframe.vect.
* stacks.c: Adjusted for new debug frame structure.
(RELOC_INFO, RELOC_FRAME): New macros.
(stack_depth, read_frames): Use them, and new scm_debug_frame
element 'info', instead of magically knowing that eval frames have
an info pointer sitting after vect.
(scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
RELOC_FRAME.
(scm_init_stacks): Formatting tweaks.
Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
Give GCC more control flow information, so it can be sure that
variables aren't used uninitialized.
* error.h (scm_error, scm_syserror, scm_syserror_msg,
scm_sysmissing, scm_num_overflow, scm_out_of_range,
scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
scm_misc_error): Tell GCC that these functions never return.
* struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
out the field type, call abort if SCM_ASSERT returns, to placate
the optimizer.
* stacks.c (scm_make_stack, scm_last_stack_frame): abort if
scm_wta ever returns. We can't handle this case anyway, and this
gives the optimizer more information.
* unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
scm_wta ever returns.
In some cases, the code is fine, but GCC isn't smart enough to
figure that out; this usually happens when one variable is only
initialized and used when a particular condition holds true, and
we know that condition will never change within a given invocation
of the function. In this case, we simply initialize the variables
to placate the compiler, hopefully to a value which will cause a
crash if it is ever actually used.
* print.c (scm_iprin1): Initialize mw_pos.
* read.c (scm_lreadrecparen): Initialize tl2, ans2.
* throw.c (scm_ithrow): Initialize dynpair.
* unif.c (scm_uniform_vector_ref): Initialize cra.
* struct.c (init_struct): Initialize prot.
* mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
* strports.c (scm_eval_0str): Don't return uninitialized garbage
if EXPR contains no expressions.
Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
* eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
cause an infinite loop (???). So much for the algebraic
equivalency of variable-sized arrays and alloca...
Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
* backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
a SCM boolean, not a C boolean.
Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
* gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
(scm_must_malloc, scm_must_realloc): Added a hysteresis to the
rules for raising scm_mtrigger. Previously, unfortunate but not
unlikely circumstances could result in almost constant invokation
of the gc. Now, this situations should be less likely, but they
are not prevented completely.
Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
* numbers.c (scm_fuck): Procedure removed; looks like old test
code.
* numbers.h: Prototype removed.
Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
* debug.h (scm_debug_frame): Change `vect' member from an in-line
array to a pointer, to match my Nov 21 change in eval.c.
Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* libguile.h: Added #include "libguile/backtrace.h", #include
"libguile/stacks.h".
* strings.c (scm_string scm_make_string scm_string_ref
scm_string_set_x scm_string_equal_p scm_string_append):
Bugfix according to scm patch from Aubrey Jaffer:
Corrected long-standing
(not (eqv? (integer->char 128)
(string-ref (make-string 1 (integer->char 128)) 0)))
bug found by John Kozak <jk@noontide.demon.co.uk>.
* strports.c, strports.h: Make scm_eval_0str return the value of
the last expression evaluated (previously, it returned void).
* strports.c, strports.h: New function: scm_read_0str. Does what
it sounds like.
Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
* simpos.c (scm_getenv): return #f if string can't be found in the
environment instead of throwing an exception, for compatibility
with numerous other systems.
Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
* Makefile.am (.c.x): Use guile-snarf.
* configure.in (AC_OUTPUT): Generate guile-snarf; make it
executable.
* guile-snarf.in: New file, resurrected from old guile-snarf.sh.
Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
* backtrace.c (scm_display_error_message): Made non-static, and
renamed from display_error_message.
* backtrace.h (scm_display_error_message): Added extern decl.
* throw.c (uncaught_throw): Use it to display the error message.
Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
* inet_aton.c: Use #if 0, not #ifdef 0.
Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
* ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
to convert the returned value.
(scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
the offset argument.
Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
Add new interface to catch/throw, usable from C as well as
Scheme.
* throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
(scm_internal_catch): New function, replaces...
(scm_catch_apply): Deleted.
* throw.c (scm_catch_apply): Deleted; replaced with a more general
mechanism which is a bit more code, but can be used nicely from C
and implement the Scheme semantics as well.
(scm_internal_catch): This is the replacement; it's named after
the analogous function in Emacs.
(scm_catch): Reimplemented in terms of the above.
(struct catch_body_data, catch_body, catch_handler): New
functions, used by scm_catch.
* root.c (cwdr): Reimplemented in terms of scm_internal_catch.
(struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
support for new cwdr.
* Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
Oct 30.
Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
* acconfig.h: Added DYNAMIC_LINKING symbol.
* configure.in: Add option and checks for dynamic linking.
* dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
dynl.h: New files for dynamic linking support.
* Makefile.am (libguile_a_SOURCES):
Added "dynl.c".
(modinclude_HEADERS): Added "dynl.h".
(EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
"dynl-vms.c".
* init.c (scm_boot_guile_1): Call
scm_init_dynamic_linking to initialize dynamic linking support.
Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
* init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
(as we Schemers say). It needs to be global, so that I can tweak
it for the proper operation of unexec.
(scm_boot_guile_1_live): New variable, see above.
Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
* guile-snarf.sh: Removed.
* PLUGIN/guile.libs: Added dependency for -lm.
* acinclude.m4: Renamed from aclocal.m4.
* PLUGIN/greet: Removed.
* Makefile.am, aclocal.m4: New files.
* configure.in: Updated for Automake.
Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
* eval.c (scm_definedp): Use top_level_lookup_closure_var
and not top_level_lookup_thunk_var.
Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
* Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
* eval.c (scm_definedp): Incompatibly changed to be a builtin
Scheme function, instead of syntax. Single argument is now a
symbol.
Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
* ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
scm_ra_divide): Properly terminate statements passed as arguments
to IVDEP macros. (Thanks to Bernard Urban.)
* eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
with non-constant sizes. (Thanks to Bernard Urban.)
Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
It's an "eval closure", not an "eval thunk." A thunk is a
function of no arguments.
* root.h (struct scm_root_state): Renamed
top_level_lookup_closure_var from top_level_lookup_thunk_var.
(scm_top_level_lookup_closure_var): Renamed from
scm_top_level_lookup_thunk_var.
* root.c (mark_root): Uses changed.
* gdbint.c (gdb_eval, gdb_binding): Uses changed.
* init.c (scm_start_stack): Uses changed.
* eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
Change scheme-visible name to *top-level-lookup-closure* from
*top-level-lookup-thunk*.
Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
* gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
* gc.c (struct scm_heap_seg_data): Doc fixes.
* gc.c (scm_gc_sweep): Empty all segments' freelists before
sweeping. Then, prepend each segment's free cells to its
freelist, rather than wiping out the old value. (Thanks to Marius
Vollmer.)
* gc.c (which_seg, scm_map_free_list, scm_newcell_count,
scm_check_freelist, scm_debug_newcell): New functions and
variables, for debugging freelist problems.
* pairs.h (SCM_NEWCELL): New debugging version added.
* gc.h (scm_debug_newcell): Added extern declaration, used by
debugging version of SCM_NEWCELL.
Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
On some systems <libc.h> conflicts with <unistd.h>, and should not
be #included at all.
* aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
* acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
* configure.in: Call it.
* posix.c, filesys.c: Use its results to decide whether or not to
#include <libc.h>.
* configure, scmconfig.h.in: Rebuilt with autoconf and
autoheader.
Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
* fports.c (scm_stdio_to_port, scm_open_file): Set the port's
pointer to the stdio stream before calling scm_setbuf0, so the
latter will be able to retrieve it. I'm surprised this didn't
segfault earlier. (Thanks to Christopher Lee.)
Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
of `lazy-catch'.
Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
number of stack narrowing specifier pairs. The first specifier in
a pair controls inner border, the second the outer border. A
number means cut that number of frames, a procedure object means
cut until that object is found in operator position in a frame.
* root.c (cwdr): Bugfix.
* read.c: Recording of positions disabled by default.
* procs.c (scm_closure_p): New function.
* posix.c (scm_tmpnam): New function.
* load.c: Added #include "throw.h".
(scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
ends with '/'.
* load.c, load.h (scm_read_and_eval_x): New function.
* eval.c: Renamed debug option "deval" to "debug".
(scm_eval_x): `eval!' is no longer accessible from the scheme
level. Motivation: We can't allow operations which introduce
glocs into the scheme level. Guile's type system can't handle
these as data. Use `eval' or `read-and-eval!' as replacement.
* debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
SCM_CONSP since this is a macro!; Set vframe.prev to
scm_last_debug_frame instead of 0. In this way we can look
"above" the virtual start stack frame if we wish.
(scm_debug_hang): New function: Useful for debugging Guile in
certain tricky situations. Will probably be removed later...
* debug.h: Changed semantics of debug option "backtrace". This
option now only indicates whether we want automatic backtrace at
an error.
Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* ports.c: #include "filesys.h"
(scm_char_ready_p): input_waiting renamed and moved to filesys.c.
* filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
Motivation: This is system specific code which is related to file
I/O. It also may use select. Added code by Gary Houston to
detect presence of character in stdio buffers.
* libguile.h: #include "libguile/libpath.h"
* Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
SCM_SITE_DIR; Install libpath.h among the other include files.
* load.c, load.h (scm_sys_package_data_dir): New function.
Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* stacks.h: Bugfix: Don't use tail-array length field as stack
length field! This screwed GC.
Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* _scm.h: Added #ifndef around definition of macros min and max.
* __scm.h: Added hooks for threads to plugin to in ints protection
macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
the main code in these macros duplicated and spread over multiple
files. Renamed SCM_THREADS_SWITCHING_CODE ->
SCM_THREAD_SWITCHING_CODE.
Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
* snarf.h: New file.
* guile-snarf.sh: New file.
* Makefile.in (inner_h_files): Added snarf.h
(ancillary, install, uninstall, distclean): Added actions for
guile-snarf.
(.c.x): Use guile-snarf.
(guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
(gen_c_files): Note that these depend on guile-snarf.
* _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
now in "snarf.h". Added #include "snarf.h" to get them.
* libguile.h: Added #include "snarf.h".
(Patches applied and tweaked by Jim Blandy.)
Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
* socket.c: Use K&R style declaration for 'close'; the GNU coding
standards suggest against providing prototypes for system
functions. Thanks to Greg Troxel.
Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
* strports.c (scm_eval_0str): New function.
#include "read.h", to get prototype for scm_read.
* Makefile.in (strports.o): Update dependencies.
* strports.h: New prototype.
* numbers.c (scm_integer_p): Renamed from scm_int_p; change its
scheme name from "int?" to "integer?". It seems to do the job.
* numbers.h: Rename prototype too.
* scmhob.h (intp): Change definition to refer to scm_integer_p. I
hope this is right.
* numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
scm_num_eq_p): Rename these according to R4RS conventions: call
them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
to making libguile R4RS compliant without ice-9...
* load.c (scm_sys_search_load_path): Search for files under all
extensions listed in the %load-extensions variable. If FILENAME
is absolute, return it unchanged, without searching the load path.
(scm_loc_load_extensions): New variable, pointing to
%load-extensions' value cell.
(scm_init_load): Initialize it, and the value it points to.
(scm_primitive_load_path): Improve error reporting.
* load.c (scm_loc_load_hook): New variable, pointing to value cell
of new Scheme variable %load-hook.
(scm_primitive_load): Apply %load-hook to filename.
Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
* configure.in: add tests for figuring out whether buffered data
is available in a FILE structure, which is needed by char-ready.
* acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
FILE_CNT_READPTR.
* simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
exceptions using misc_error instead of syserror. It seems a bit
odd to throw an exception if a string can't be found in the
environment, but it's consistent with open-file, stat etc.
(simpos.h): remove sys_ from getenv.
* posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
occurs, throw an error instead of returning errno. Return value
is now unspecified.
(numerous in posix.c and posix.h): removed superfluous sys_ from names.
Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
* filesys.c (scm_stat2scm): derive file type and permissions from
the stat mode and append them to the returned vector.
There isn't much overhead in doing this and it avoids the need to
work with S_IRUSR et al. in Scheme.
Define symbols scm_sym_regular etc.
(scm_init_filesys): don't intern S_IRUSR etc.
* load.c: change s_try_load and s_try_load_path to s_primitive_load
and s_primitive_load_path.
* eval.c, load.c, error.c (scm_wta): use scm_misc_error.
* error.h: don't declare error symbols. prototype for scm_misc_error.
* stackchk.c (scm_stack_overflow_key): defined here instead of in
error.c.
* error.c: use SCM_SYMBOL to set up error keys.
scm_misc_error: new procedure.
Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
* read.c (scm_lreadr): Recognize SCSH-style block comments; text
between `#!' and `!#' is ignored.
(skip_scsh_block_comment): New function.
* feature.c (scm_set_program_arguments): New argument, FIRST.
* feature.h: Update prototype.
* init.c (scm_boot_guile_1): Pass new argument to
scm_set_program_arguments.
Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
* init.c (scm_start_stack): Don't initialize scm_progargs here.
(scm_boot_guile): Call scm_set_program_arguments here, later than
the old initialization.
* init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
initialization procedure.
- Delete in, out, err arguments; there are other perfectly good
ways to override these when desired.
- Delete result argument; this function shouldn't ever return.
- Rename init_func argument to main_func, for less confusion.
- Delete boot_cmd argument; main_func is more general.
-Add 'closure' argument, to help people pass data to main_func
without resorting to global variables.
- Abort if reentered; don't bother returning an error code.
- Call scm_init_standard_ports to set up the default/current
standard ports; no need to pass them to scm_start_stack.
- Remove code to evaluate the boot_cmd, and start the repl; let
the user do something like that in main_func if they want.
- Remove code to package up a return value; main_func can do any
of that as needed.
- Call exit (0), instead of returning.
(scm_start_stack): Don't initialize the I/O ports here; that's
weird. Delete in, out, err arguments. Move guts to
scm_init_standard_ports, scm_stdio_to_port.
(scm_init_standard_ports): New function, to set up current and
default standard ports.
(scm_start_stack, scm_restart_stack): Make these static.
* init.h (scm_boot_guile): Adjust declaration.
(scm_start_stack, scm_restart_stack): Remove externally
visible declarations for these.
(enum scm_boot_status): Removed; now scm_boot_guile never returns.
* fports.c (scm_stdio_to_port): New function. Its guts used to be
written out several times in scm_start_stack.
* fports.h: New declaration for the above.
* feature.c (scm_set_program_arguments): New function.
* feature.h: New declaration for the above.
* ports.c: Formatting tweak.
Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
* pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
for obtaining the address of a car or cdr field. Motivation:
&SCM_CXR make assumptions about the internal structure of the
SCM_CXR selectors.
* eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
Motivation: see SCM_CXRLOC.
* pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
srcprop.h, tags.h, throw.c, unif.c: Added new selectors
SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
Motivation: Safer use. Some other macros are defined in terms of
these operations. If these are defined using the SCM_SETCXR
(<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
to inefficiency and an <e1> with side-effects could potentially
break. Also, these particular operations are heavily utilized in
the garbage collector. In unoptimized code there will be a
measurable speedup.
* alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
vports.c: Cleaned up use of pairs: Don't make any special
assumptions about the internal structure of selectors and
mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
(Among other things, this change makes it easier to build Guile
with certain compilers which have problems with casted lvalues.)
Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
* stacks.c: Improve selection of relevant stack frames when making
a stack object. Introduce one level of indirection in the stack
object to make it possible to "narrow" to a certain region of the
stack. This facilitates making use of more clever algorithms (not
implemented) for selecting relevant frames and gives a cleaner
design since selection of frames can be done independently of
extraction of frames from the real stack.
(scm_stack_id): Also take #t as argument which means look at
current stack.
* stacks.h: In struct scm_stack: Turn field frames into a pointer.
Turn n_tail into an integer directly representing current number
of frames in stack. Add field tail.
* ports.c (scm_port_line_x, scm_port_column_x): New mutators.
* debug.c (scm_make_memoized): Made it available at scheme level.
(scm_unmemoize, scm_memoized_environment): Bugfix: Check for
SCM_NIMP before applying heavier predicates in argument checking.
(scm_local_eval): Also take memoized object as argument.
* backtrace.c (scm_display_error): Just a safety measure: Stacks
aren't created with zero length, but should such a strange
creature suddenly turn up...
Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
* hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
`del', for the sake of C++ compilers. (Patch applied by JimB.)
Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
* variable.c (scm_make_variable): Make the name hint optional, as
documented.
(anonymous_variable_sym): Renamed from variable_sym. All uses
changed.
* load.c (scm_primitive_load, scm_primitive_load_path): Renamed
from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
of scm_primitive_load_path was also changed to
"primitive-load-path", from "%try-load-path". Callers changed.
We'd like to respect the convention that a function named
"try-mumble" should behave just like the function called "mumble",
but return #f instead of signalling some error.
* load.h: Rename prototypes.
Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
* print.c (make_print_state, grow_print_state), print.h: Modified
the print state representation: Don't use a tail array for
recording of circular references. Resizing of the print state
structure invalidates the print state pointer. To avoid passing
around an indirect print state reference to all printing
functions, we instead let the print state reference a resizable
vector.
Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
* alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
Don't crash when passed an improper list terminated by a
non-immediate value.
Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
Allocate data for structures on an eight-byte boundary, as
required by the tagging system.
* struct.c (alloc_struct): New function.
(scm_make_struct, scm_make_vtable_vtable): Call it.
* struct.h (scm_struct_n_extra_words): Bump to 3.
(scm_struct_i_ptr): New "field".
* gc.c (scm_gc_sweep): When we need to free the data, use the
information stored by alloc_struct to find the beginning of the
block allocated to the structure, so we can free it.
Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
* init.c (scm_boot_guile_1): Moved scm_init_struct in front of
scm_init_stacks.
* debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
(scm_debug_info): New member: id.
* stacks.c: Stacks are now represented as structs; Stacks have an
id given to them by `start-stack'.
(scm_last_stack_frame): Added predicates `stack?' and `frame?'.
* stacks.h: Added declarations of scm_stack_p and scm_frame_p;
Changed stack representation.
* debug.c (scm_procedure_name): Try procedure property `name' for
compiled closures aswell.
* gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
* eval.c: scm_i_name moved to gsubr.c
(scm_m_define): Record names of all kinds of procedure
objects. (Earlier, only closures were recorded.)
* procprop.h: Added declaration of scm_i_name.
* gsubr.c: Added global scm_i_name. Added #include "procprop.h".
(scm_make_gsubr): Record names of compiled closures.
Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
* debug.c, debug.h: Removed obsolete code.
* continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
stacks.c: Renamed regs --> scm_contregs.
* print.c (scm_free_print_state): Cleanup print state before
returning it to pool. It is better to do it here than in
scm_prin1 since scm_prin1 is called often.
* srcprop.c (scm_source_properties, scm_set_source_properties_x,
s_set_source_property_x): Check that first argument is a pair or a
memoized object.
* srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
scm_i_line, scm_i_column and scm_i_breakpoint global.
* init.c: Added #include "backtrace.h" and #include "stacks.h".
(scm_boot_guile_1): Added calls to scm_init_backtrace and
scm_init_stacks.

* async.c: Moved `min' macro to _scm.h.
* debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
SCM_BACKTRACE_INDENT.

* print.h: Added selector SCM_PRINT_STATE.
* print.c: New functions: scm_make_print_state,
scm_free_print_state.
* print.h: Added declarations for scm_make_print_state,
scm_free_print_state.
* debug.c (scm_m_start_stack): New acro.
* debug.h: Small cleanup.
* init.c (scm_boot_guile_1): Moved scm_init_debug below
scm_init_eval.

Vollmer.)
More prototype-related changes from Marius Vollmer:
* gdb_interface.h: Wrapped header file in #ifdef/#endif
* gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
* ports.h (ptobfuns): Added prototypes. This means some casting in
fports.c.
* fports.c: Added casts for initializations, since the functions
are defined to take FILE * as their stream argument, not SCM.
* fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
* genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
to `char *str_data' to conform to prototype.
Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
* error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
* __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
* stime.c, stime.h: use SCM_P method.
Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
* eval.c (scm_nconc2last): Don't accept an empty list; apply must
be given at least two arguments. Insist that lst's last element
be a list, but don't make any requirements of its predecessors.
Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
* eval.c (scm_nconc2last): Revert last change; there seems to be
other stuff going on here.
Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
* eval.c (scm_nconc2last): Make sure that each element of lst
(which is a list of argument lists, except for the tail) is a
proper list, i.e., finite and terminated by '().
Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
* unif.c (scm_ra_set_contp): Localize `inc' declaration.
Clarifies flow.
* struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
symbolic name for the tag, scm_tc3_cons_gloc, instead of just
saying "1".
* vectors.c (scm_make_vector): Fill vectors with the undefined
value, to help make Guile Scheme code more portable to other
Schemes.
* symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
* symbols.h, tags.h: Doc fixes.
Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
* async.c (scm_take_signal): Doc fixes.
Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
* numbers.c (scm_divbigint): When the remainder is zero, we don't
want to subtract it from the modulus; we just want to leave it
alone.
Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
* init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
`scm_init_threads'.
* throw.h (scm_catch_apply): Removed the `lazyp' argument.
* throw.c (scm_catch_apply): Finished implementation of
`lazy-catch'.
Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
* filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
check.
(scm_init_filesys): set "i/o-extensions" feature.
include feature.h.
Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
* Makefile.in (root.o): Correct dependencies.
Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
* Makefile.in: Added dependency entry for root.o.
* continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
* init.c (scm_start_stack): Set initial root continuation number
to 0.
* procs.c: New function: scm_thunk_p.
* procs.h: Added declarations of scm_thunk_p.
* root.c: Renamed `call-with-new-root' -->
`call-with-dynamic-root'.
(cwdr): Removed allocation of new root state. This should be done
separately by use of scm_make_root.
(scm_apply_with_dynamic_root): New function: Does what it
sounds like. Needed when spawning threads.
* root.h: Added member last_debug_frame to root state.
Added #include "libguile/debug.h"
* throw.c: Renamed scm_catch --> scm_catch_apply and added more
arguments. The motivation is that code in root.c needs catch
functionality, and we want to avoid code duplication.
New functions: scm_catch, scm_lazy_catch. These are wrappers for
scm_catch_apply. scm_lazy_catch is intended to introduce catch
handlers that run without popping the stack into the dynwind
chain.
* throw.h: Added prototypes for scm_catch_apply and
scm_lazy_catch.
Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
* root.h (scm_root, scm_set_root): Decouple thread support details
by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
SCM_SET_THREAD_LOCAL_DATA.
* print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
and tortoise scanning loop.
Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
* Makefile.in: Rebuild dependencies.
* libguile.h: #include "libguile/print.h" before "smob.h", since
the latter uses the print_state structure.
* throw.c (scm_ithrow): Use the correct variable when checking to
see if a given element of scm_dynwinds is a valid catch.
* throw.c (scm_ithrow): If scm_dynwinds has invalid list
structure, abort; don't just silently ignore the garbage.
* _scm.h: #include "print.h" here, since it seems to be used just
about everywhere.
* eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
strports.c, unif.h: Don't #include "print.h".
Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
* feature.h (scm_loc_features): Removed external declaration.
(Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
* feature.c (scm_init_feature): Added threads feature (needs to be
initialized here, since features doesn't exist when
scm_init_threads is called).
* libguile.h: Added #include "libguile/../threads/threads.h".
(This is a kludge to get thread support working. This should be
fixed.)
* configure.in, acconfig.h: Added flags for thread support.
* scmsigs.c: Define `signal' to be `pthread_signal' if using
mit-pthreads.
* gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
root.c:mark_root.
* _scm.h: Added conditional #include "threads.h"
* __scm.h (SCM_ASYNC_TICK): Added call to macro
SCM_THREADS_SWITCHING_CODE.
* init.c (scm_start_stack): Call `scm_make_root' to dynamically
allocate the basic dynamic root object.
(scm_boot_guile): Added call to scm_init_root.
* root.c, root.h: Added root smob.
(cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
functions: Implements dynamic roots mostly according to spec in
SCM manual. Main difference is that the second argument is a
throw handler rather than an error "thunk".
* root.h: Added declaration of scm_init_root.
* root.c: Added #include "genio.h", #include "smob.h", #include
"pairs.h", #include "throw.h", #include "dynwind.h", #include
"eval.h"
(scm_init_root): Added #include "root.x".
* throw.c: Added #include "stackchk.h"
(scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
can be used in scm_call_with_new_root; Added reenabling of stack
checking when catching a throw.
Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
* list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
* list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
element is not found, as per R4RS.
Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
* list.c: Doc fixes throughout.
Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
* strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
declare the char * to be const. Avoids a warning in rgx.c.
* ports.h: spelling fix.
* filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
error messages.
* load.c (scm_sys_try_load_path): throw an error if file not found
(like it says it in NEWS).
Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
* symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
PROPS slot to '(), not #f; it's an empty alist.
* throw.h, throw.c: Use SCM_P instead of #if hair.
Remove special support for uncaught throws; see throw.c for
rationale.
* throw.c (uncaught_throw): New function.
(scm_ithrow): Call uncaught_throw if we don't find a throw
target; don't mess with scm_bad_throw_vcell.
(scm_bad_throw_vcell): Variable deleted.
(scm_init_throw): Don't initialize it.
* throw.c (scm_ithrow): Don't let outer key matches shadow inner
#t catches.
Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
* numbers.c (scm_istr2int): If the number is short (as most
numbers are), just call scm_small_istr2int to deal with it.
(scm_small_istr2int): New function, created by un-#ifdefing the
non-bignum version of scm_istr2int and renaming it.
Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
* load.c (scm_sys_try_load): don't check whether value returned
by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
Change the Scheme name from %try-load to primitive-load.
* error.c (scm_error): convert a NULL message to SCM_BOOL_F.
Can avoid passing a message, allowing it to be derived in the
error handler (e.g., if we want to throw to the key both from
Scheme and C).
Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
* print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
references now have a new appearance which is more compact and
also gives a clue about what the target of the reference is.
By setting parameters in the print state, more fancy printing can
be achieved. This is used by the (not yet commited) backtrace
code.
Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
* eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
"print.h"
* print.c: Added #include "struct.h". Removed function
scm_prlist.
* print.h: Modified prototypes for scm_iprlist, scm_prin1 and
scm_iprin1. Removed prototype for scm_prlist.
* arbiters.c (prinarb),
async.c (print_async),
debug.c (prindebugobj, prinmemoized),
eval.c (prinprom, prinmacro),
filesys.c (scm_fd_print, scm_dir_print),

smob.h (scm_smobfuns),
srcprop.c (prinsrcprops),
throw.c (prinjb),
unif.c, unif.h (scm_raprin1, rapr1),
variable.c (prin_var): Changed argument `int writing' to
`scm_print_state *pstate'.
* init.c (scm_boot_guile): Moved scm_init_struct upwards so
that it will be called before scm_init_print.
* print.c (scm_prin1): Print states are now allocated when calling
scm_prin1 and then passed around to all printing functions as an
argument. A cache `print_state_pool' enables reuse of print
states.
(scm_make_print_state): New function.
(scm_iprin1): Adaption to print states.
(scm_iprlist): An initial "hare and tortoise" scan brings down
time complexity to O (depth * N). (Better time complexity will be
achieved when the printing code is completely rewritten.)
Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
* aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
it gets done whether or not the cache variable has a value.
Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
Distinguish #f and ().
* __scm.h: #undef SICP.
* pairs.h (SCM_EOL): Delete this definition, equating it with
SCM_BOOL_F.
* tags.h (SCM_EOL): Give it a new definition here; I think I found
the value it used to have. Doc fixes, too.
Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
* struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
Lord's implementation of structs, allowing for tail arrays as
described in the manual. Also fixed some bugs. (Both the interface
and the implementation should be improved.)
* read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
* print.c, print.h: Closures now print like #<procedure foo (x)>.
People who whish to see the source can do `(print-enable 'source)'.
Removed #ifdef DEBUG_EXTENSIONS.
Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
* filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
integer (assuming for now accepting an integer is a good thing).
* error.c, fports.c: replace use of %S in lgh_error args with %s.
%S will be used instead for write'ing arguments.
* unif.c (scm_transpose_array): change arguments in the SCM_WNA
asserts. fix a few other asserts.
(scm_aind, scm_enclose_array, scm_array_in_bounds_p,
scm_uniform_vector_ref, scm_array_set_x,
scm_dimensions_to_unform_array): change args in
SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
scm_substring_fill_x): likewise.
gsubr.c (scm_gsubr_apply): likewise.
eval.c (SCM_APPLY): likewise.
* eval.c (4 places): replace scm_everr with lgh_error or
scm_wrong_num_args.
* error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
scm_memory_error): new procedures.
scm_everr: deleted. can use scm_wta, dropping first two args.
scm_error: convert NULL subr to SCM_BOOL_F.
* __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
SCM_ARGERR.
* stackchk.c (scm_report_stack_overflow): use lgh_error instead
of scm_wta.
* error.c, error.h: new error keys: scm_arg_type_key,
scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
scm_misc_error_key.
scm_wta: reimplement using lgh_error instead of scm_everr.
Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
* gdbint.c: scm_lread now has one more argument.
* ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
scm_port_\1; Added mutator scm_set_port_filename_x (used when
loading source from non-file ports, which, e. g., happens when
using the Emacs interface).
* fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
object.
* read.c: Added code for recording of positions of source code
expressions; New functions: recsexpr, scm_lreadrecparen;
_scm_make_srcprops --> scm_make_srcprops
(scm_flush_ws): Removed updating of positions counters. This work
is already done by scm_gen_getc
* read.h: Added prototype for scm_lreadrecparen
* print.c: Added #include "alist.h"
* eval.c: Added #include "hash.h"
* eq.c: Added #include "ramap.h"
* options.c: Documentation fixes.
* srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
(scm_init_srcprop): Adjusted size of initial source-whash. Name
changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
--> scm_make_srcprops
* srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
_scm_make_srcprops --> scm_make_srcprops; Remove one layer of
function calls in the definition of the whash access macros.
Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
* init.c (scm_boot_guile): Add level of indirection to
scm_boot_guile_1() to ensure that stack base pointer is properly
initialized. There was no guarantee that variable i was the
highest/lowest variable on stack (i.e. the call frame of
scm_boot_guile was not completely protected from gc).
Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
* ports.h (scm_port_table): put back file_name, it will be used to
support debugging. Undo related changes in fports.c, ioext.c,
ports.c, gc.c.
Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
* ports.h (scm_port_table): remove file_name member for now, it seems
undesirable.
* fports.c (scm_open_file): don't set file_name in PTAB.
(prinfport): don't use file_name in PTAB.
* ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
* ports.c (scm_add_to_port_table): don't intialize file_name.
(scm_port_file_name): remove for now.
* gc.c (scm_gc_mark): don't mark PTAB file_name.
* fports.h (scm_mkfile): prototype deleted.
* fports.c (scm_mkfile): merged into scm_open_file to simplify.
* debug.c, unif.c: use scm_out_of_range instead of
wta for range errors (ASSERT still needs work).
* error.c, error.h (scm_out_of_range): new procedure.
* error.c, error.h (scm_out_of_range_key): new key.
* posix.c (scm_sync): #else was missing.
* error.c, error.h: append _key to names scm_num_overflow and
scm_system_error.
* __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
of consing an empty list.
(SCM_SYSERROR etc.): move into error.c, make them procedures instead
of macros, saves code and string space.
error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
lower case. Rename scm_syserror_m to scm_syserror_msg.
error.h: prototypes for new procedures.
Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
* numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
* error.c, error.h: setup scm_num_overflow key.
* __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
Remove definition of SCM_OVSCM_FLOW.
* fports.c (scm_open_file): use SCM_SYSERROR_M.
* __scm.h: SCM_SYSERROR_M: new macro for system errors with an
explicit message and args.
* error.c, error.h, __scm.h: change system_error_sym to
scm_system_error.
* error.c (system_error_sym): remove leading %% from the Scheme name
"%%system-error".
* __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
* __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
renamed. (These were introduced by unsupervised name
substitution.)
Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
* print.c: Added code for detection of circular references during
printing. (init_ref_stack, grow_ref_stack): New functions. Added
a hook for printing of closures (accessible via print options).
This leads to a split of calls to scm_iprin1 into two classes:
elementary print operations (e. g. the code which prints a smob)
still use scm_iprin1 while top level calls (like scm_display) use
scm_prin1. scm_prin1 begins by clearing the data structure used
to record reference information.
* print.h: Added declarations of scm_prin1 and scm_prlist.
* strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
* gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
* gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
* error.c (err_head): scm_iprin1 --> scm_prin1
* debug.c: Adjusted header comment.
* tags.h: Typo.
Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
* strerror.c: Doc fix.
Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
* gdbint.c (gdb_read): Now possible to run during GC.
(unmark_port, remark_port): New functions.
* symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
* read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
of allocating a new string object. Also, increase size by
the factor 2 instead of 1.5.
Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
* __scm.h (SCM_P): Corrected to run under traditional C.

* continuations.c (scm_dynthrow): Redundant declaration removed.
* debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
Definition typos corrected.
* debug.h: Missing declarations of functions in debug.c added
(lots).
* eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
Missing declarations to functions in eval.c added.
* filesys.c: Possibly uninitialized variable rv.
* gc.h (scm_object_addr, scm_unhash_name): Missing
declarations of functions defined in gc.c added.
* genio.c: Possible typos str_data -> wstr_data. ???
* genio.c: Possibly unintended shadowing of local variable
`int c' (gotos out of scope of inner `c'). ???
* init.c: Uninitialized `SCM last' may be used.
* ioext.h: (scm_sys_isatty_p): Typo.
* list.h (scm_list_head): Missing prototype for function in
list.c added.
* numbers.c (scm_two_doubles): Changed from extern to static
(is used only within numbers.c).
* numbers.h: Repeated declarations removed.
* ports.h (scm_close_all_ports_except): Declaration for the
function defined in ports.c added.
* posix.h: Missing declarations added.
* procs.h (scm_make_subr_opt): Missing declaration added.

Redundant declarations removed (they are in ramap.h).
* variable.h (scm_make_udvariable,
scm_make_undefined_variable): Declaration corrected to
correspond variable.c.
* vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
Missing declarations added.
Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
* Makefile.in (distclean): Don't forget to delete fd.h.
Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
* fd.h.in, tags.h: Trivial cleanups.
* marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
marksweep.h just declared functions from gc.c.
* gc.h, libguile.h: Don't #include "marksweep.h".
* Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
dependencies updated.
* libguile.h: Don't #include "files.h"; it's been deleted.
* files.c (scm_sys_delete_file): Moved to filesys.c.
File is now empty; deleted.
* files.h: Deleted.
* filesys.c: scm_sys_delete_file is now here. Remove
#if's; they seem to rely on remnants of an old portability
regimen. If the problems come up again, solve them properly,
using autoconf. Specifically: Don't test M_SYSV, and #define
remove to be unlink if it's #defined; don't use remove just
because HAVE_STDC_HEADERS is #defined.
* filesys.h: Add declarations for scm_sys_delete_file.
* Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
files.o, files.h, files.c, and files.x.
* init.c: Don't #include "files.h", and don't call scm_init_files.
Use SCM_P instead of PROTO; the latter intrudes on the user's
namespace.
* params.h: Deleted; definition of SCM_P moved to...
* __scm.h: ... here, where it replaces PROTO macro.
* libguile.h, smob.h: Don't #include "params.h".
* continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
smob.h: Fix prototypes accordingly.
* Makefile.in: Update dependencies.
(inner_h_files): Remove params.h.
* gc.c: #include "gc.h"; every module should include its header,
to let the compiler cross-check the declarations against the
definitions.
* eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
simpos.h: #include "libguile/__scm.h".
Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
* init.c: Don't forget to #include smob.h and init.h.
* Makefile.in: Dependencies updated.
* smob.h: Use PROTO instead of #if __STDC__.
* continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
* __scm.h: Doc fixes.
* __scm.h, libguile.h: Use "quotes" in the #includes, not
<angles>; this allows `make depends' to work properly.
* libguile.h: #include smob.h and pairs.h before the others; they
define typedefs used by other headers.
C files should #include only the header files they need, not
libguile.h (which #includes all the header files); the pointless
recompilation was wasting my time.
* Makefile.in (all .o dependency lists): Regenerated.
* libguile.h: Don't try to get a definition for size_t here...
* __scm.h: Do it here.
* _scm.h: Since this is the internal libguile header, put things
here that all (or a majority) of the libguile files will want.
Don't #include <libguile.h> here; that generates dependencies on
way too much. Instead, get "__scm.h", "error.h", "pairs.h",

* stackchk.h: #include "libguile/debug.h",
* print.h, read.h: #include "options.h", since everyone who uses
either of these files will need that.
* smob.h: #include "ports.h", "genio.h", and "print.h", since
anyone who uses this file will need them to define the smob
printing functions. Also, get markers.h, since people will need
to #define the mark functions.
* smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
* ports.h: ... to here.
* ports.h (scm_port_table_size): Explicitly give type as 'int';
don't rely on archaic C default type rules.
* fports.h: #include "libguile/ports.h", since you need that in
order to parse this.
* genio.h: #include "libguile/print.h", because you need that to
parse this; don't bother #including "ports.h", since print.h gets
that.
* error.h: Don't #include "pairs.h"; _scm.h will do that now.
* eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
this; it's now a reference to an element of *scm_root.
* debug.h: Don't #include "options.h"; the compiler won't be able
to find that once the headers are installed; instead, #include
"libguile/options.h".
* gc.h: Same, with marksweep.h.
* mbstrings.h: Same, with symbols.h.
* scmhob.h: Same, with _scm.h.
* smob.h: Same, with params.h.
* Makefile.in (depends): Don't nuke scmconfig.h and the generated
C files; there's no need for this, and it forces recompilations
unnecessarily.
Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
* error.c (scm_error): declare scm_error_callback.
* error.h: prototype for scm_error_callback.
* __scm.h: define lgh_error.
(SCM_SYSERROR): redefine using lgh_error.
Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
* error.c (scm_error): new procedure.
* error.h: prototype for scm_error.

dependencies are within libguile properly.
Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
* Makefile.in (.c.x): Simplify; there's no need to run this rule
when scmconfig.h doesn't exist.
* load.c (scm_sys_try_load): Correct spelling.
* feature.c (scm_loc_features): Make this static.
* Makefile.in (libpath.h): Omit trailing slash from path. We
shouldn't require it of users, so why put it here?
Move code to initialize and search %load-path from ice-9 to C
code, so we can use the load-path to find the ice-9 boot code;
this makes it easier to run Guile without installing it. See
corresponding changes in guile/Makefile.in.
* feature.c: Move stuff concerned with the load path to load.c.
(scm_compiled_library_path): Deleted.
Don't #include libpath.h here.
* feature.h: Don't mention scm_compiled_library_path.
* load.c: #include "libpath.h" here, as well as <sys/types.h>,
<sys/stat.h>, and <unistd.h> (if present).
(R_OK): #define if the system hasn't deigned to.
(scm_loc_load_path): New variable.
(scm_init_load_path, scm_sys_search_load_path,
scm_sys_try_load_path): New functions.
(scm_init_load): Initialize scm_loc_load_path to point to the
value cell of the Scheme %load-path variable.
* load.h: Add declarations for scm_sys_search_load_path,
scm_sys_try_load_path.
* init.c: Call scm_init_load_path.
* Makefile.in (feature.o, load.o): Dependencies updated.
* load.c, load.h: Rewrite using PROTO macro.
Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
* gc.c (scm_cellp): New function: C predicate to determine if an
SCM value can be regarded as a pointer to a cell on the heap.
* gc.h: Added declaration of scm_cellp.
* gdb_interface.h: New file: The GDB interface header from the GDB
distribution.
* gdbint.c: New file: GDB interface.
* gdbint.h: New file: GDB interface.
* libguile.h: Added #include <libguile/gdbint.h>.
* init.c (scm_boot_guile): Added scm_init_gdbint.
* Makefile.in: Added gdb_interface.h, gdbint.[hc].
Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
found if object files and source are kept separate).
Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
* feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
* configure.in: Don't substitute the values of TCL_SRC_DIR and
TK_SRC_DIR; they're not relevant any more.
* Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
* configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
* PLUGIN/guile.config (xtra_cflags): Include .. in the header
search path, so we can find the <libguile/MUMBLE.h> headers.
* Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
* Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
implicit in the .c.o rule.
(.c.x): Don't mention ALL_CFLAGS here; its value is included in
$(CC) already.
Put the library path in a header file, instead of passing it on
the command line in every compilation.
* Makefile.in (libpath.h): New target.
(feature.o): Depend on libpath.h.
(clean): Delete libpath.h.
(ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
* feature.c: ... #include "libpath.h" here.
* .cvsignore: Ignore libpath.h.
Don't install the unwashed masses of Guile header files in the
main #include path; put most of them in a subdirectory called
'libguile'. This avoids naming conflicts between Guile header
files and system header files (of which there were a few).
* Makefile.in (pkgincludedir): Deleted.
(innerincludedir): New variable; this and $(includedir) are enough.
(INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
(installed_h_files): Divide this up. Now this variable lists
those header files which should go into $(includedir) (i.e. appear
directly in the #include path), and ...
(inner_h_files): ... this new variable says which files appear in
a subdirectory, and are referred to as <libguile/mumble.h>.
(h_files): List them both.
(install): Create innerincludedir, not pkgincludedir. Put
the installed_h_files and inner_h_files in their proper places.
(uninstall): Corresponding changes.

(they're both "inner" files).
Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
* Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
* posix.c: Doc fixes.
Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
* socket.c: Don't include a prototype for inet_aton; just use a
K&R style declaration, to avoid warnings but minimize the chance
of conflicts with the system.
On NextStep, <utime.h> doesn't define struct utime, unless we
#define _POSIX_SOURCE before #including it.
* aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
* acconfig.h: New comment text for above CPP symbol.
* configure.in: Call it.
* posix.c: #define _POSIX_SOURCE if it seems necessary.
* configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
in the list.
* posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
testing for __EMX__.
* posix.c: #include <libc.h>, if it exists.
* posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
don't even know if the latter exists.
* posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
* posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
header files don't.
(scm_init_posix): Use them when initializing the Scheme constants
of the same name.
Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
* Makefile.in (libdir, includedir, bindir): Use the
autoconf-supplied values, instead of deriving them ourselves.
(pkgincludedir, datadir, pkgdatadir): New variables.
(install, uninstall): Put the header files in a special
subdirectory, not in the main search path.
* Makefile.in (ALL_CFLAGS): Provide the proper value for
LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
* Makefile.in (IMPLPATH): Deleted; never used.
* Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
on the Tcl/Tk source any more.
(INCLUDE_CFLAGS): Remove references to the above.
* Makefile.in (version.o): Corrected dependencies.
Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>

* version.c: New file.
Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
* symbols.c (scm_strhash): scm_downcase is now a function, not an
array; use it appropriately. Since GCC is quite happy to
subscript functions, it never warned us about this; we should use
-Wpointer-arith in the future. I guess we never tested
case-insensitivity.
Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
* socket.c: Doc and copyright fixes.
Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>

Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
* socket.c: Added declaration of inet_aton to avoid compiler
warning. (Hope this solution is correct.)
* stime.c: Added declaration of ftime. (This is missing in
Solaris 2 headers.)
Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
* configure, scmconfig.h.in: Updated, using autoconf and autoheader.
* Makefile.in (c_files): add strerror.c.
* strerror.c: new file from Emacs' sysdep.c.
maybe configure should also check for sys_errlist.
* configure.in (AC_REPLACE_FUNCS): add strerror.
Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
* debug.c (scm_init_debug): Added initialization for
scm_evaluator_traps.
* debug.h, debug.c: Various name changes.
(Mostly prefixing with SCM_.) Renamed "debug-options" -->
"debug-options-interface". See commentary in options.c.

Also added a long explanatory commentary.
* eval.c, print.h, print.c, read.h, read.c: Modifications to
run-time options.

checking.
Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>

--enable-debug will include the debugging code into libguile.a.
* continuations.c (scm_make_cont): Enlarged the #if 0 around
scm_relocate_chunk_to_heap.
* debug.c: New file: low-level debugging support. It also
includes support for debugging with gdb. (The extensions to gdb
are written by Per Bothner at Cygnus.)
* debug.h: New file: low-level debugging support.
* eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
argument pairs. Extensive modifications to the debugging
evaluator. Added "SECTION:" commentaries to clarify what happens
when, during double compilation. Renamed EVALIMP --> EVALIM.
Renamed EVAL --> XEVAL. Removed function evalcar. Defined
evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
the beginning of the file. New procedure: scm_unmemocopy.
Added some global state variables needed by the debugging
evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
check_entry, check_apply, check_exit, debug_options and
evaluator_traps. New acro: undefine.
* eval.h: Renamed EVAL --> XEVAL.
* gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
--> scm_make_weak_key_hash_table.
* init.c (scm_restart_stack, scm_boot_guile): Added initialization
of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
* libguile.h: Conditionally include debug.h
* objprop.c (scm_object_properties, scm_set_object_properties_x):
scm_object_properties shouldn't return handle. `handle' now gets
initialized in scm_set_object_properties_x. scm_object_properties
doesn't any longer create an entry in scm_object_whash.

(Bug found by A. Green.)
* weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
* weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
* libguile.h: #include "objprop.h"; I guess this was forgotten.
* init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
and should be called by the final client.
Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
* gc.h: Use the PROTO macro when declaring functions.
* gc.c: Use the PROTO macro when declaring static functions.
Remove the CPP hair around function definitions.
* gc.c (scm_init_storage): Initialize scm_asyncs.
* libguile.h: #include "__scm.h" before testing the STDC_HEADERS
preprocessor symbol; "__scm.h" is where it might get #defined.
* __scm.h: Similar: #include <scmconfig.h> before testing
HAVE_LIMITS_H.
* __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
* init.c (scm_boot_guile): Add init_func argument; call
(*init_func) instead of calling scm_appinit; it's ucky to
hard-code names for the user's procedures.
* init.h (scm_boot_guile): Adjust declaration.
* __scm.h (PROTO): New macro, for declaring functions with
prototypes.
* init.h (scm_start_stack, scm_restart_stack): Use PROTO;
eliminate all the __STDC__ conditionals.
(scm_boot_guile): Add declaration.
* init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
Remove __STDC__ conditionals around function definitions; the
declarations in init.h will provide the same information, more
usefully.
* __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
complain about it in the error message; the error message is
adequate without that note, and there's nothing the user can do
about it.
Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
* Makefile.in (ancillary): Drop def.sed.
* posix.c (scm_init_posix): Use numeric values, rather than
CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
F_OK. The symbols aren't available on some systems, and I'm
pretty sure their values are fixed by common widespread practice.
* ioext.c (scm_init_ioext): Code here defined them too; remove it.
More functions unavailable on some systems.
* configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
check for.
* configure, scmconfig.h.in: Updated, using autoconf and autoheader.
* posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
stub that signals an error as the #else.
* Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
* Fixes motivated by Petr Adamek <adamek@mit.edu>:
* unif.c: include ramap.h.
* read.c (endif): case_insensative_p renamed case_insensitive_p.

* ports.c: include sys/ioctl.h.
* scmconfig.h.in: add HAVE_SYS_IOCTL_H.
* configure.in: check for sys/ioctl.h.

* posix.c: fewer ttyname declarations.
* fports.c: include <string.h> not "string.h".
* init.c, ioext.c: include string.h and unistd.h.
* gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
* async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
genio.c, simpos.c, vports.c: include string.h.

scm_sizet to int.
(scm_addr_buffer_size): change type from scm_sizet to int.
(accept, getsockname, getpeername, recvfrom): change type of tmp_size
from scm_sizet to int.
* error.c: include unistd.h.
* __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
defined.
* Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
* __scm.hd, def.sed: deleted.
Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
Changes for NeXT, suggested by Robert Brown.
* configure.in: Call AC_TYPE_MODE_T.
(AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
NeXT. Put header file list in alphabetical order.
* configure, scmconfig.h.in: Regenerated.
* filesys.c [HAVE_LIBC_H]: #include <libc.h>.
* filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
for strerror.
* acconfig.h: New file, providing documentation for the CPP
symbols defined in configure.in
* acconfig-1.5.h: Removed; superceded by the above.
Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
* ioext.c (scm_sys_fdopen): fix the port-table assignment.
* fports.c (scm_open_file): don't return #f, throw error.
* ioext.c (fileno): renamed from %fileno.
(soft-fileno): deleted.
* ports.c (scm_port_revealed): don't need to check for -1 from
scm_revealed_count.
(scm_set_port_revealed_x): return unspecified, not #f.

* fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
* scmconfig.h.in: add HAVE_STRUCT_LINGER.
* configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
* filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
This is necessary on Ultrix, and doesn't hurt portability.
* Makefile.in (dist-dir): New target, implementing a new dist system.
(installed_h_files): Put in alphabetical order.
Remove duplicate entries for markers.h and unif.h.
(c_files): Remove duplicate entries for markers.c.
(ancillary): Renamed from anillery; all uses changed. Remove
PLUGIN; it's a directory, and needs special treatment in dist-dir.
Remove all the ../doc/* files; doc/Makefile.in handles that.
* Makefile.in (libobjs): Remove duplicate entry for markers.o.
* Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
every if must have an else, or else the whole command has a
non-zero exit code whenever the if's condition is false.
Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
* posix.c: include string.h.
Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>

(scm_list_head): added list-head for rapidly chopping argument
lists off of longer lists (and similar).
Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
* objprop.c (scm_object_property): assq the cdr of the whash
handle for obj, not the handle itself.
Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
* gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
weak hash tables last of all marking to avoid an obscure gc bug.
WARNING: circular lists stored in a weak hash table will hose us.
Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
* vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
new functions similar to scm_substring_move_left_x and
scm_substring_move_right_x.

* guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
removed to a separate library
* init.c (scm_boot_guile): copied from guile-tcl.c.
Initialization specific to tcl interpreters removed.
Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
* ports.c (scm_ports_prehistory): size malloced here doesn't
matter so long as it is non-0 (got rid of "* 4").
Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
* gscm.h: gscm_mkarray eliminated (presumably was not being used
since its definition was bogus).
Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
* mallocs.[ch]: back again (for rx at least).
Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
* ports.c: removed functions relating to the mapping between ports
and descriptors. (That stuff is unix-specific and should be collected
in a separate library).
* ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
(Tom Mckay@avanticorp.com)
Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
* gc.c (scm_gc_sweep): Immediates in weak vectors were not
handled correctly (SCM_FREEP was applied to them) -- test for
NIMP. Keys in weak hash tables were spuriously (though harmlessly)
being overwritten with #f. (brown@grettir.bibliotech.com)
Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
* gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
for a specific symbol or for all symbols.
Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>

* list.c (scm_last_pair): map '()=>'()
Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>

Added procedures to access those fields.
Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>

* gc.c (scm_gc_end): simulate a signal at the end of each GC.
(scm_gc_stats): return an assoc of useful data. Replaces "room"
and the stats reporting formerlly built into repl.

GC statistics keeping moved to gc.c.
Other statistics keeping can be done from Scheme.
REPLS are now written in Scheme.
Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>

* error.c (scm_init_error): init system_error_sym here, not in repl.c.
* feature.c (scm_compiled_library_path): moved here from repl.c.
This file is for stuff relating specifically to Scheme libraries
like slib.
* eval.c (scm_m_define): don't give warning about redefinition, don't
check verbosity.
NOTE: this should throw a resumable exception with parameters --
the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
* repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
* error.c: scm_warn eliminated.
* read.c (scm_lreadr): extra right paren gets an error, not a warning.

lose exit_report, growth_mon.
* gscm.c: got rid of verbosity functions.
Tue Feb 20 00:19:10 1996 Tom Lord <lord@beehive>

between the call to procedurep and use.
* error.c (scm_everr):
* gc.c (fixconfig):
* gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
but less so.
* strports.c: don't reveal the port's string to the caller
because it changes size.
(stputc stwrite): check/change the strings length with interrupts
blocked.
* objprop.c (scm_set_object_property_x &c): use the generic
hashing functions and be threadsafe.
* eval.c (scm_unmemocar): do this operation in a thread-safe way.
(per suggestion jaffer@gnu.ai.mit.edu).
* mbstrings.c (scm_multi_byte_string): guard against argument list
changing length.
* strings.c (scm_make_string): loop cleanup
* unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer
a scheme function.
* weaks.c (scm_weak_vector): guard against argument list
changing length.

variable automicly.
* vectors.c (scm_vector): while filling the new array,
guard against a list of fill elements that grows after
the vector is allocated.
* hashtab.c -- new file: general hash table
functions. hash, hashq, hashv, hashx.

Mon Feb 19 09:38:05 1996 Tom Lord <lord@beehive>
* symbols.c: made the basic symbol table operations atomic.
* root.c &c.: collected stack-specific global state.
linum/colnum etc *should* be port-specific state.
* struct.c (scm_init_struct): init the first struct type during
initialization to fix a race condition.
* continuations.c (scm_dynthrow): pass throwval in the 'regs'
object, not in a global.

* throw.c (_scm_throw): Pass throwval on the stack, not in a global
(suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
* *.[ch]: namespace cleanup. Changed all (nearly) exported CPP
and C symbols to begin with SCM_ or scm_.
Sun Feb 18 15:55:38 1996 Tom Lord <lord@beehive>

* async.c: New support for interrupt handlers.
Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
* symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
set the multi_byte flag correctly in symbols. This is wrong.
intern_obbary_soft and msymbolize should take an extra parameter.
Also, weird multibyte symbols don't print correctly.
The weird symbol syntax is also a bit bogus (emacs doesn't quite
cope).
Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
* symbols.c (scm_string_to_obarray_symbol): obarray == #f means
use the system symhash. == #t means create an uninterned symbol.
Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>

Sat Jan 27 12:36:55 1996 Tom Lord <lord@beehive>
* eval.c (scm_map): added argument type checking.
(kawai@sail.t.u-tokyo.ac.jp)
* gscm.c (gscm_set_procedure_properties_x): parameter "new" => "new_val"
for C++. (Seth Alves <alves@gryphon.com>)
(gscm_cstr): uses an uninitialized local variable causing
segv. (kawai@sail.t.u-tokyo.ac.jp)
* lvectors.c (scm_get_lvector_hook):
In guile-ii, the lvector code was broken. It was fixed in guile-iii.
It seems to me like if it is broken again in guile-iv...Here is a patch.
"! || (LENGTH (keyvec) == 0))"
(From: Mikael Djurfeldt <mdj@nada.kth.se>)
* gscm.c (gscm_sys_default_verbosity):
incorrectly declared for non-__STDC__
(Tom_Mckay@avanticorp.com)
* ports.c (scm_setfileno): Tweak the macro a bit
to make it easier to port to systems that use
more than a single structure field to hold a descriptor.

Give a warning, not an error, for unrecognized modes.
* eval.c (SCM_CEVAL):
static char scm_s_for_each[];

(see next entry)
* struct.c (scm_sys_struct_set_x):
static char s_sys_make_struct[];
static char s_sys_struct_ref[];
static char s_sys_struct_set_x[];
Rearrange code to eliminate those forward decls for the sake of
broken compilers.

* eval.c (SCM_APPLY): variables "debug_info" -> dbg_info.
Works around a compiler bug on some machines. (Tom_Mckay@avanticorp.com)
* _scm.h (CxR functions): #define CxR SCM_CxR => #define CxR(X) SCM_CxR(X)
Works around a compiler bug on some machines. (Tom_Mckay@avanticorp.com)
* lvectors.c (scm_lvector_set_x): avoid VELTS (VELTS (...)[..]) which
can turn into an obscure gc bug.
* chars.c (scm_char_p): fixed PROC call.
* gscm.h (gscm_vset): use scm_vector_set_x not (the missing)
scm_vector_set.
Tue Jan 23 13:29:40 1996 Tom Lord <lord@beehive>
* elisp.c (new file): dynamic scoping and other bits for
elisp. Don't use this yet unless you specificly want to
hack on elisp emulation.
* dynwind.c (scm_dowinds): When entering or leaving a dynamic
scope created by scm_with_dynamic_bindings_operation_x, swap
the bindings of that scope with the corresponding globals.

relocate the continuation stack chunks registered on the wind chain
to the heap.
Sun Jan 21 19:31:17 1996 Tom Lord <lord@beehive>
* eval.c (SCM_CEVAL): if the function position evaluates
to a macro, process it accordingly. (Previously, macros were
handled only if the function position was a symbol naming a
variable bound to a macro).
Sat Jan 20 23:21:37 1996 Tom Lord <lord@beehive>
* eval.c (scm_m_set): allow multi-variable set! like
(set! x 1 y 2 z 3).
Wed Dec 6 02:40:49 1995 Tom Lord <lord@beehive>
* ports.h fports.c vports.c marksweep.c gc.c strports.c: moved the
STREAM of ports into the port table and replaced it with a

scm_downcase functions that are safe for extended character sets.
Changed the range of integer->char.
Changed the type of SCM_ICHR.

know that it's safe to pass an object to gscm_get_type?)
(gscm_get_type): Fix tyop in error message.
* variable.c (scm_variable_ref): fixed assertion test.
(Robert STRANDH <strandh@labri.u-bordeaux.fr>)
* gscm.h: fixed several prototypes, notably gscm_vref.
Add gscm_is_eq and temporarily commented out gscm_eq (see
the note in gscm.h near gscm_eq if this change effects your
code).
(Reported by Mark Galassi <rosalia@sstcx1.lanl.gov>)
* pairs.c (scm_obj_length): see next entry.
* gscm.h (gscm_obj_length): A way to get an integer
