Raw Blame History

Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
* Makefile.am (libpath.h): Include the values of all the standard
Makefile directory variables. Print a message, but don't print
all the commands.
(versiondat.h): Print a message, but don't print all the commands.
* load.c: #include "alist.h".
(init_build_info): New function.
(scm_init_load): Call it.
* Makefile.in: Regenerated.
Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
* root.c: Establish a reliable catch-all handler for the new root.
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
control to cwdr_outer_body.
(struct cwdr_body_data): New field, handler, to allow cwdr to pass
the user's handler through to cwdr_outer_body.
* throw.c (scm_handle_by_message): Move guts into....
(handler_message): New static function.
(scm_handle_by_message_noexit): New function.
* throw.h (scm_handle_by_message_noexit): New prototype.
* __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)

address for FSF.
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,
init.c, net_db.c, options.c, options.h, ports.c, print.c, read.c,
script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
throw.c: Update copyright years; these files have been worked on
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_freopen, scm_duplicate_port, scm_fdopen), net_db.c
(scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
(scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
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.
* script.c (scm_ice_9_already_loaded): New variable.
(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).
* net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
* configure, scmconfig.h.in: Regenerated.
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.

LIBOBJS.
* _scm.h, libguile.h: threads.h lives in this directory now.
* 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_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
Merge GH interface library into libguile.
* gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
* Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
_scm.h to ...

(pkginclude_HEADERS): Add variable, to get gh.h installed.
(THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
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.
(scm_init_filesys): New symbols for use with fcntl.

when PROC is receiving no arguments.
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.

sequences.h too.
stime.h, posix.h: update prototypes.
(bdtime2c, setzone, restorezone): new static procedures.

(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.

* 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.c (scm_primitive_load, scm_read_and_eval_x,
scm_primitive_load_path): remove case_insensitive_p, sharp arguments.

(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>

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, 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.

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.

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.
* _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
removed.
* async.c: Calls to scm_sysintern corrected.
* async.h (scm_async_clock): Redundant declaration removed.
* 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.
* socket.h (scm_sys_gethost): Missing declaration added.
* socket.h: Redundant declarations removed (they are in fdsocket.h).
* srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
Missing declarations added.
* stime.h (scm_get_internal_real_time): Repeated declarations removed.
* struct.c: Uninitialized variable `SCM answer' may be used.
* unif.c (l2ra): Declaration prototype.
* unif.c (scm_array_equal_p): Dummy definition removed (it is
defined in ramap.c).
* unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
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",

* 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.

<libguile/__scm.h>. This allows 'gcc -MM' to determine which
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>
* libguile.h: #include "version.h"
* init.c (scm_boot_guile): Call scm_init_version.
* gscm.c (gscm_run_scm): Call scm_init_version.
* configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
GUILE_VERSION): AC_DEFINE these.
(acconfig.h): #undef the above symbols.
* Makefile.in (libobjs): Add version.o.
(installed_h_files): Add version.h.
(c_files): Add version.c.
(gen_c_files): Add version.x.
(version.o): New rule.
(alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,

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>
* debug.c: Fixed and improved gdb support.
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.
* options.h, options.c: Options now have documentation strings.
Also added a long explanatory commentary.
* eval.c, print.h, print.c, read.h, read.c: Modifications to
run-time options.
* gscm.c, init.c, root.c, throw.c: Bug fixes:
last_debug_info_frame is now updated in all cases.

checking.
Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
* __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
Added option STACK_CHECKING.

* Makefile.in: Added {debug,options,srcprop}.{h,c}
* __scm.h: Removed symbols for debugging support.
* acconfig.h: Added symbols for debugging support.
* configure.in: Added user option for debugging support.
--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.

* srcprop.c: New file: source properties.
* srcprop.h: New file: source properties.
* throw.c (jbsmob): Jump buffers are now correctly allocated.
(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.
* ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
* ports.c: include sys/ioctl.h.
* scmconfig.h.in: add HAVE_SYS_IOCTL_H.
* configure.in: check for sys/ioctl.h.
* ports.c: include <malloc.h> not "malloc.h".
* mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
* fports.c: remove ttyname and tmpnam declarations.
* 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.
* socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
* fdsocket.c (getsockopt, setsockopt): change type of optlen from
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.
* ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
* 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>

Remove leading % from scheme names.
Do not return error values, call SCM_SYSERROR or similar.
* __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
* struct.c (scm_init_struct): new file.
Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
* list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
(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.
Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
* init.c (scm_boot_guile): prevent gc with scm_block_gc not
scm_gc_heap_lock!

Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
* strports.c (scm_strprint_obj): convenience function. C for
(lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
* 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>

keys and weak values confused).
Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
* list.c (scm_last_pair): map '()=>'()
Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
* pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
Generalized assoc and hash-table functions.

(possibly triggering gc) before setting the tag of the corresponding
ports handle.
* pairs.c (scm_delq_x): never throw an error.

* ports.c (scm_add_to_port_table): Added fields
to port table entries: file_name, line_num, col.
Update these in open_file, gen_getc and gen_ungetc.
Added procedures to access those fields.
Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>

Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
* numbers.c (scm_exact_p): This function no longer
implements "integer?".
Thu Feb 22 20:56:16 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.
* repl.[ch]: removed.
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>
* cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky
conservatively marked objects).

* 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.
* repl.c, marksweep.c, gc.c (various):
lose exit_report, growth_mon.
* gscm.c: got rid of verbosity functions.
Tue Feb 20 00:19:10 1996 Tom Lord <lord@beehive>
* throw.c (scm_ithrow): guard against the bad-throw hook changing
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.c (scm_builtin_variable): check for/make a built-in
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.
* tags.h: made wvect an option bit of vector.
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.
(suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
* 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>
* gsubr.c (scm_gsubr_apply): statically allocate the
array of arguments (bothner@cygnus.com).
Sat Feb 17 20:20:40 1996 Tom Lord <lord@beehive>
* scmsigs.c: Simplified to use async rountines.
* 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>
* strings.c (scm_make_shared_substring): build'em.
It might better to keep a table of these and use one
less cons-pair per shared-substring.
Tue Feb 6 17:45:21 1996 Tom Lord <lord@beehive>
* strings.c (scm_string_shared_substring): create shared
substrings. (Doesn't handle mb strings yet).
* mbstrings.c (scm_print_mb_string): handle RO strings.
* print.c (scm_iprin1): print substrings as their non-substring
counterparts (dubious).
* marksweep.c (scm_gc_mark scm_gc_sweep): handle RO and MB
strings.
