eliminating some warnings.
* unif.c, strports.c, print.c, options.c: Fix some warnings on
mis-use of SCM/long
* gc.c, gc.h: Added scm_return_first_int(), and added comment re:
what the scm_return_first* functions do.
name for a Scheme object (now a void*), and SCM as 32 bit word for
storing tags and immediates (now a long int). Introduced
SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
code in the process: arbiter.c (use macros), unif.c (scm_array_p),
displaying the expected type. Use SCM_LISTn in a couple places
instead of scm_cons-ing by hand.
* __scm.h: Added SCM_ASSERT_TYPE macro.
* validate.h, scm_validate.h: Added the former, as a renamed
version of the latter with SCM_ASSERT_TYPE used in
SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
* Makefile.am: Rename scm_validate.h to validate.h.
* *.c, *.h: Include validate.h, not scm_validate.h (old name's
prefix was superfluous).
added append docs from R4RS.
* strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
Thanks Dirk Hermann!
* chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
* *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
Drop use of SCM_P for function prototypes... assume an ANSI C
compiler. Thanks Dirk Hermann!
regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
strings.c, variable.c: Added lots of documentation, cleaned up
some existing documentation. Occasionally changed formal params
to match docs. Also folded an #ifdef into the inners of a
primitive instead of having two copies of the primitive
(`get-internal-real-time', from stime.c)
net_db.c, sort.c, stacks.c, unif.c: Use SCM_WTA, SCM_MISC_ERROR
where possible.
* symbols.c (scm_sysintern0): Fixed the function name in a
scm_misc_error invocation.
* print.c (scm_simple_format): Do not need SCM_COERCE_SUBSTR, and
use scm_return_first to ward off latent GC bug that Mikael caught.
* async.c: Use SCM_VALIDATE_ASYNC_COPY one place where it wasn't
used before but should've been.
strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
consistency with the other macros dealing with immediate
characters. (Similar to INT -> INUM change a week or so ago).
net_db.c, read.c, socket.c: Update error messages to use ~A for
%s, ~S for %S to work with new `simple-format' format and be
standardized better.
* print.h, print.c (scm_simple_format): Added `simple-format'
primitive. It's the old scm_display_error, with ARGS now a rest
parameter, and the destination first instead of last (and a couple
new capabilities inspired by `format' -- #t as destination means
current-output-port, #f means return the formatted text as a
string.
* gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
* backtrace.c (scm_display_error_message): Rewrote to use
scm_simple_format() procedure.
* __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
posix.c: Eliminated a bunch of SCM_NIMP(..)s that are now
redundant with the safer macros. Patch from Dirk Hermann applied
by hand. Thanks Dirk!
* scm_validate.h: Added SCM_VALIDATE_VECTOR_OR_DVECTOR for some
uses in random.c.
* ramap.c: whitespace change.
* scm_validate.h: Added SCM_VALIDATE_THREAD.
* *.c: Remove SCM_NIMP(X) when it is an extraneous pre-test given
that SCM_FOOP macros all now include SCM_NIMP in their expansion.
This simplifies lots of code, making it far more readable.
* guile-doc-snarf.awk.in: Added.
* ports.c (s_scm_pt_member): Fixed validation.
* guile-doc-snarf.in (filename): Use basename in order to strip
away path.
* debug.c (scm_make_iloc, s_scm_proc_to_mem): Added missing
semicolon.
(scm_memcons, scm_memcons, mem_to_proc): Renamed function name
strings to new form.
* backtrace.c (set_print_params_x): Fixed GUILE_PROC macro.
* tags.h (SCM_UNBOUND): New iflag which is needed for some time to
mark the unboundness of a GOOPS slot. (Added now in order to
correct a oversight. Should probably be removed again and
replaced with SCM_UNDEFINED when the corresponding code in GOOPS
is rewritten.)
* print.c (scm_isymnames): Added printed representation for
SCM_UNBOUND.
* eval.c (SCM_CEVAL): Bugfix: Added check for unbound slot in
SCM_IM_SLOT_REF.
prototypes.
* eval.c: Make scm_m_mody's 3rd argument be a const char *, not a
char *. ANSI prototypes caught this.
* strorder.c: Use GUILE_PROC1 for the couple SCM_PROC1 expansions
that I missed.
* scm_validate.h: Use SCM_BOOLP for validating bools. Do not
expand macros if SCM_DOCSTRING_SNARF.
function headers and argument checking. Switched SCM_PROC,
SCM_PROC1 macros to be GUILE_PROC, GUILE_PROC1 (may change names
later, but was useful to keep old versions around while migrate)
that has docstrings and argument lists embedded in the GUILE_PROC
macro invocations that expand into a function header. Use lots of
new SCM_VALIDATE_* macros to simplify error checking and reduce
tons of redundancy. This is very similar to what I did for Scwm.
Note that none of the extraction of the docstrings, nor software
engineering checks of Scwm is yet added to Guile. I'll work on
that tomorrow, I expect.
* Makefile.am: Added scm_validate.h to modinclude_HEADERS.
* chars.c: Added docstrings for the primitives defined in here.
* snarf.h: Added GUILE_PROC, GUILE_PROC1. Added
SCM_REGISTER_PROC to be like old SCM_PROC, though old SCM_PROC
still remains for now. Changed naming convention for the s_foo
string name of the primitive to be s_scm_foo for ease of use with
the macro.
* scm_validate.h: Lots of new SCM_VALIDATE macros to simplify
argument checking through guile. Maybe some of these should be
folded into the header file for the types they check, but for now
it was easiest to just stick them all in one place.
* configure.in: add --disable-arrays option, probably temporary.
* the following changes allow guile to be built with the array
"module" omitted. some of this stuff is just tc7 type support,
which wouldn't be needed if uniform array types were converted
to smobs.
* tag.c (scm_utag_bvect ... scm_utag_cvect): don't define unless
HAVE_ARRAYS.
(scm_tag): don't check array types unless HAVE_ARRAYS.
* sort.c (scm_restricted_vector_sort_x, scm_sorted_p):
remove the unused array types.
* (scm_stable_sort, scm_sort): don't support vectors if not
HAVE_ARRAYS. a bit excessive.
* random.c (vector_scale, vector_sum_squares,
scm_random_solid_sphere_x, scm_random_hollow_sphere_x,
scm_random_normal_vector_x): don't define unless HAVE_ARRAYS.
* gh_data.c (makvect, gh_chars2byvect, gh_shorts2svect,
gh_longs2ivect, gh_ulongs2uvect, gh_floats2fvect, gh_doubles2dvect,
gh_uniform_vector_length, gh_uniform_vector_ref):
don't define unless HAVE_ARRAYS.
(gh_scm2chars, gh_scm2shorts, gh_scm2longs, gh_scm2floats,
gh_scm2doubles):
don't check vector types if not HAVE_ARRAYS.
* eq.c (scm_equal_p), eval.c (SCM_CEVAL), print.c (scm_iprin1),
gc.c (scm_gc_mark, scm_gc_sweep), objects.c (scm_class_of):
don't support the array types unless HAVE_ARRAYS is defined.
* tags.h: make nine tc7 types conditional on HAVE_ARRAYS.
* read.c (scm_lreadr): don't check for #* unless HAVE_ARRAYS is
defined (this should use read-hash-extend).
* ramap.c, unif.c: don't check whether ARRAYS is defined.
* vectors.c (scm_vector_set_length_x): moved here from unif.c. call
scm_uniform_element_size if HAVE_ARRAYS.
vectors.h: prototype too.
* unif.c (scm_uniform_element_size): new procedure.
* init.c (scm_boot_guile_1): don't call scm_init_ramap or
scm_init_unif unless HAVE_ARRAYS is defined.
* __scm.h: don't define ARRAYS.
* Makefile.am (EXTRA_libguile_la_SOURCES): unif.c and ramap.c
moved here from libguile_la_SOURCES.
* Makefile.am (ice9_sources): add arrays.scm.
* boot-9.scm: load arrays.scm if 'array is provided.
* arrays.scm: new file with stuff from boot-9.scm.
* socket.c (scm_htons, scm_ntohs, scm_htonl, scm_ntohl): new
functions for network data conversion.
* numbers.c (scm_num2long, scm_num2longlong):
throw out-of-range instead of wrong-type-arg if appropriate.
(scm_iint2str): handle -2^31 correctly.
(scm_num2long): handle -2^31 bignum correctly.
(scm_num2long_long): rewrite the bigdig case: basically copied
from scm_num2long.
numbers.h: (SCM_BITSPERLONGLONG): deleted.
* unif.c (rapr1): use sprintf instead of intprint for unsigned
longs: intprint can't cope with large values.
* numbers.c (scm_num2ulong): check more consistently that the
input is not negative. if it is, throw out-of-range instead of
wrong-type-arg.
* ramap.c (scm_array_fill_int): don't limit fill to INUM for
uvect, ivect or llvect.
Check that fill doesn't overflow short uniform array.
* __scm.h: add another long to the definition of long_long and
ulong_long.
* unif.c (scm_raprin1): use 'l' instead of "long_long" in the
print representation of llvect. read can't handle more than
one character.
(scm_dimensions_to_uniform_array): make "fill" an optional argument
instead of a rest argument.
* tags.h (scm_tc7_llvect): wasn't defined anywhere, so use the free
tag 29 for now.
* __scm.h: don't mention LONGLONGS.
* unif.c, numbers.c, eq.c, gc.c, print.c, eval.c, ramap.c:
replace LONGLONGS with HAVE_LONG_LONGS as set by configure.
* net_db.c (scm_inet_aton): throw errors using the misc-error key
instead of system-error. inet_aton doesn't set errno.
system-error isn't right in gethost either, since it's throwing
the value of h_errno instead of errno. so:
(scm_host_not_found_key, scm_try_again_key,
scm_no_recovery_key, scm_no_data_key): new error keys.
(scm_resolv_error): new procedure, use the new keys.
(scm_gethost): call scm_resolv_error not scm_syserror_msg.
* error.c: (various): use scm_cons instead of scm_listify
to build short lists.
* boot-9.scm (read-hash-extend to set up arrays): add 'l' for
long_long uniform vectors.
* networking.scm (sethostent, setnetent, setprotoent, setservent):
take an optional argument STAYOPEN. default is #f.
* readline.c (scm_init_readline): set rl_readline_name to Guile,
to allow conditionals in .inputrc.
less than two. (Thanks to Jorgen Schaefer.)
* print.c (scm_write, scm_display, scm_newline, scm_write_char):
Don't assume that the current output port is valid. Somebody
might close it. (Thanks to Bernard Urban.)
associated with subrs.

SCM_SUBR_DOC): New macros.

SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
* eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
primitives). NOTE: This means that it is now *required* to use
SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
obscured representation that will be removed in the future anyway,
so backward compatibility is no problem here).
* numbers.c: Converted most numeric primitives (all but bit
comparison operations and bit operations) to dispatch on generic
if args don't match.
* eval.c, eval.h (scm_eval_body): New function.
* objects.c (scm_call_generic_0, scm_call_generic_1,
scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
functions.
* eval.c (SCM_CEVAL): Apply the cmethod directly after having
called scm_memoize_method instead of doing a second lookup.
* objects.h (scm_memoize_method): Now returns the memoized cmethod.
* procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
scm_sysintern so that the binding connected with the subr name
isn't cleared when we give set = 0.
port, return the print state associated to it in the current print
chain, if one exists;
(scm_port_with_print_state): New procedure: Associate a
print-state with a port.
(scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
(scm_printer_apply): Wrap port and pstate as a smob;
(print_state_printer): Removed.
newline. A bit faster, and definitely hairier.
(scm_read_line): Count newlines here instead.
* strings.c (scm_take_str): New function.
(scm_take0str): Reimplement in terms of scm_take_str. * strings.h
(scm_take_str): New declaration. * ioext.c (scm_read_line): Use
scm_take_str, to avoid copying the string.
Add some simple-minded support for line buffered ports.
* ports.h (SCM_BUFLINE): New flag for ports.
* init.c (scm_init_standard_ports): Request line-buffering on
the standard output port.
* * ports.c (scm_mode_bits): Recognize 'l' as a request for line
buffering.
(scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
and there's a newline to be written, flush the port.
* ports.c: (scm_lseek): clear buffers even if just reading current
position.
* fports.c (local_fclose): call local_fflush unconditionally.

strports.c: take care of rw_active and rw_randow.
fports.c: scm_fport_drain_input: removed. do it all in ports.c.
strports.c (scm_mkstrport): check that pos is reasonable.
ioext.c (scm_ftell, scm_fseek): use lseek.
(SCM_CLEAR_BUFFERS): macro deleted.
ioext.c (redirect_port: use ptob fflush, read_flush.
ports.h (scm_ptobfuns): add ftruncate.
ports.c (scm_newptob): set ftruncate.
adjust ptob tables.
* ports.c (scm_ftruncate): new procedure.
fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.
strports.c (st_seek, st_grow_port): new procs.
fports.h (scm_port): change size types from int to off_t.
ports.c (scm_init_ports): initialise the seek symbols here
instead of in ioext.c.
strports.c (scm_call_with_output_string): start with an empty
string, so seek and ftruncate can be used.
* ports.h (scm_ptobfuns): add a read_flush procedure which is the
equivalent to fflush for the read buffer.
* ports.c (scm_newptob): set read_flush.
ports.c (void_port_ptob): set read_flush.
fports.c (local_read_flush): new proc. add to ptob.
strport.c (st_read_flush): likewise.
vport.c (sf_read_flush): likewise.
fports.h (struct scm_fport): remove random member. there's nothing
left but fdes. leaving it as a struct to allow for future changes.

ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
ptob proc if the read buffer is filled.
* ports.h (scm_port): add a rw_random member and replace
reading and writing members with rw_active member.
SCM_PORT_READ/SCM_PORT_WRITE: new values.
* ports.h (struct scm_port_table): add writing and reading members
to replace write_needs_seek: it isn't good enough for non-fports.
ports.c, ioext.c, fports.c: corresponding changes.
(struct scm_port_table): give it a typedef and rename to scm_port.
ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
corresponding changes.

* * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
and generalised to all port types.
* scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
signals (it was only being done for handlers installed from Scheme).
Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
waiting for input caused an EINTR error from read.
* ports.h (struct scm_port_table): make all the char members
unsigned, so they convert to int without becoming negative if large.
* fports.c (scm_fdes_wait_for_input): forgot to check compilation
with threads enabled. rename this procedure to
fport_wait_for_input and take a port instead of a fdes.
use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
* readline.c (scm_readline): Applied a patch from Greg Harvey to
get readline support working again: use fdopen to get FILE objects.
* gc.c (scm_init_storage): install an atexit proc to flush the
ports.
(cleanup): the new proc. it sets a global variable which can be
checked by the ptob flush procs to avoid trying to throw
exceptions during exit. not very pleasant but it seems more reliable.
* fports.c (local_fflush): check terminating variable and if set
don't throw exception.
* CHECKME: that the atexit proc is installed if unexec used.
* throw.c (scm_handle_by_message): don't flush all ports here.

and move to ioext.c.
* fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
* ports.c (scm_char_ready_p): check the port buffer and call the
ptob entry if needed.
* ports.h (scm_ptobfuns): input_waiting_p added. change all the
ptob initialisers. use it in char-ready
* ioext.c (scm_do_read_line): moved from ports.c. make it static.
* vports.c (sfflush): modified to write a char (since softports
currently use shortbuf.)
* fports.c (scm_standard_stream_to_port): moved to init.c and
made static.
* init.c (scm_init_standard_ports): make stdout and stderr
unbuffered if connected to a terminal. with stdio they
were line-buffered by default.
* ports.h (scm_ptobfuns): change fflush return to void.
change flush proc definitions.
* strports.c (scm_call_with_output_string): get size from
buffer instead of port stream.
(scm_strprint_obj): likewise.
(st_flush): new proc.
* ports.h (struct scm_port_table): added write_end member,
as an optimisation. set it where write_buf_size is set.
* ports.h (struct scm_port_table): change stream from void *
back to SCM. SCM presumably must be large enough to hold a
pointer (and probably vice versa but who knows.)
(SCM_SSTREAM): deleted. change users back to SCM_STREAM.
(scm_puts): rewritten
* fports.c (local_ffwrite, local_fputs): removed.
* strports.c (stputc, stputs, stwrite): dyked out (FIXME)
* vports.c (sfputc, sfputs, sfwrite) likewise.
* ports.c (write_void_port, puts_void_port): removed.
(putc_void_port, getc_void_port, fgets_void_port): likewise.

use ptob for seek. take ptob instead of fport arg.
* ports.h (struct scm_port_table): new member write_needs_seek,
replaces reading member in fport struct.
* vports.c (sfgetc): store the getted char into the buffer.
rename to sf_fill_buffer and install it for fill-buffer in ptob.
the Scheme interface is still a procedure that gets a char.
(scm_make_soft_port): set up the port buffer (shortbuf).
* fports.c (local_fgetc, local_fgets): deleted.
* strports.c (stgetc): likewise.

* fports.h (SCM_FDES_RANDOM_P): new macro. use it in
scm_fdes_to_port and scm_redirect_port.

new port. reset fp->random.
* fports.c (scm_fdes_to_port), ports.c (scm_void_port),

* ports.c: install scm_flush_all_ports to be run on exit.
ports.c fports.c ioext.c posix.c socket.c net_db.c filesys.c:
removed all uses of SCM_DEFER/ALLOW ints for now. they were mainly
just protecting errno. some may need to be put back.
* scmsigs.c (take_signal): save and restore errno while this
proc runs.
*fports.c (print_pipe_port, local_pclose, scm_pipob): deleted.
