1 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
3 * eval.c (scm_lookupcar1): New procedure to cope with a race
4 condition during lookup (when using threads).
5 (scm_lookupcar): Implement in terms of scm_lookupcar1.
6 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
9 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
11 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
12 supplied. (Change from Tim Pierce.)
14 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
16 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
17 23:47:01 1997" changelog: Slots are now initialized with `#f' by
18 default and not `()'. `#f' is the canonical non-value in Scheme,
21 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
23 * struct.c (struct_printer): New variable that holds a handle on
24 the Scheme variable *struct-printer*. This variable can be set by
25 Scheme code to override the printing of structures.
26 (scm_print_struct): If struct_printer is set, call it. If it is
27 not set, or returns #f, print the structure in the old fashion.
28 Include "eval.h" for scm_apply.
30 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
32 * struct.c (scm_struct_ref, scm_struct_set_x): Use
33 scm_struct_i_n_words to get the number of fields, not
34 -scm_struct_n_extra_words.
36 On the route to fancier struct printing:
37 * struct.c (scm_print_struct): New function to print a structure.
38 Include "genio.h" to support it. This function doesn't do
39 anything interesting right now, but I think it should be here
41 * struct.h: Include "print.h" and add prototype for
43 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
44 print structures ourself.
46 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
48 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
49 before applying the handler in case it doesn't return.
51 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
53 * scmsigs.h, async.h: updated.
55 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
58 * posix.c (scm_uname): interpret only negative values as an error.
59 Solaris normally returns a positive value.
61 * script.c (scm_compile_shell_switches): if we are not going into
62 an interactive repl, set scm_mask_ints to zero so that asyncs can
65 * simpos.c (scm_system): don't ignore/unignore signals around
68 * posix.c (scm_open_pipe): don't ignore/unignore signals around
71 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
72 done in boot-9.scm instead.
74 * scmsigs.c, async.c: Major rewriting of signal handling code.
75 (scm_sigaction): new procedure.
76 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
78 (scm_raise): return unspecified, throw error on failure.
80 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
82 * regex-posix.c (scm_init_regex_posix): Register the "regex"
83 feature, to help boot-9.scm decide whether to import the regex
86 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
88 * eval.c: Include scmconfig.h at the beginning of the file so that
89 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
92 * regex-posix.c: #include "_scm.h" before conditionally #including
93 <regex.h>; the former defines HAVE_REGCOMP.
95 * regex-posix.c: #include <regex.h> conditionally, so the file is
96 CPP'able (for dependency scanning) even on systems that don't have
99 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
101 Add new R4RS-compliant syntax for keywords.
102 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
103 regardless of the setting of the `keywords' read option.
104 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
105 can be re-read no matter what the setting of the `keywords' read
108 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
110 Add support for POSIX regular expressions.
112 * regex-posix.c, regex-posix.h: New files. (Some code
113 is taken liberally from rx/rgx.c in the old Guile dist.)
115 * init.c: Include regex-posix.h.
116 (scm_boot_guile_1): Call scm_init_regex_posix.
118 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
119 Add regex-posix.[ch] sources.
120 * Makefile.in: Regenerated.
122 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
123 to do this automatically? It didn't for me, bleh.)
125 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
127 * fports.c (print_pipe_port): New function.
128 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
129 latter doesn't even take the right arguments.
131 * Makefile.am: Increment shared lib revision number. I think
132 sometimes the uninstalled Guile finds the installed shared lib;
133 Gord says doing this might help. As things turned out, I can't
135 * Makefile.in: Regenerated.
137 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
138 passing it as the closure argument to scm_boot_guile. (Bill
141 * ports.c (print_void_port, putc_void_port, puts_void_port,
142 write_void_port, flush_void_port, getc_void_port, close_void_port,
143 noop0): Use ANSI prototypes instead of K&R declarations, so the
144 initialization of void_port_ptob gets aggressively type-checked.
145 Fix arguments of print_void_port and write_void_port. (Bill

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

210 throw.c: Update copyright years; these files have been worked on
211 significantly in 1997, but only had copyright years for 1996.
212 Also, change name of copyright holder on some from Mikael
213 Djurfeldt to Free Software Foundation; he has signed papers
214 assigning the changes to the FSF.
216 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
217 reason not to give the user the option.
219 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
220 Return #f on end-of-file when scanning table (i.e. when called
221 with no arguments). Try to catch errors, when we can.
222 * posix.c (scm_getgrgid, scm_getpwuid): Same.
224 * script.h (scm_shell_usage, scm_compile_shell_switches): New
225 external declarations. These are useful.
227 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
229 * posix.c: don't include <sys/select.h> or define macros for
230 select, since they were not used in this file.
232 * filesys.c (scm_select): make the fifth parameter microseconds,
233 not milliseconds. let the fourth parameter be either a real value
234 or an integer or #f. The first, second and third arguments can
235 now be vectors: the type of the corresponding return set will be
237 (set_element, get_element): new static procedures.
239 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
241 * strports.c (scm_eval_string): New function.
242 (scm_eval_0str): Trivially re-implemented in terms of
244 * strports.h (scm_eval_string): New extern decl.
246 * net_db.c (h_errno): Add extern decl for this.
248 * fports.c (local_pclose): New function.
249 (scm_pipob): Use it in the initializer here.
252 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
253 Use a meaningful error message when signalling an error. For
254 this, scm_gethost must check h_errno rather than errno.
256 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
258 * Makefile.in: Regenerated, using automake-1.1p.
260 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
262 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
265 * script.c (scm_compile_shell_switches): don't append (quit) if
267 (scm_shell): call scm_exit_status and exit on the result of the
270 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
272 Ensure that shared substrings are handled properly when passed to
273 a system call or other foreign function. Many thanks to Tim
275 * symbols.h (SCM_COERCE_SUBSTR): new macro.
276 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
277 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
278 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

280 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
281 (scm_display_error_message): use RO macros when strings may be RO.
282 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
283 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
284 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

293 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
295 * error.c (scm_error): Add newline to error message.
297 * init.c (scm_init_standard_ports): Doc fix.
299 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
301 * dynl-shl.c: Completely replaced with new code from Bernard
304 * script.c (scm_ice_9_already_loaded): New variable.
305 (scm_compile_shell_switches): Use it.
307 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
309 * filesys.c (scm_input_waiting_p): add missing third argument to
312 * stime.c (scm_localtime): copy the result of localtime before
313 calling gmtime in case they share a buffer.
314 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
317 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
319 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
321 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
323 * Makefile.am (check-local): New target, which causes 'make check'
324 to run gh_test_c and gh_test_repl, with some trivial input.
325 * Makefile.in: Rgnrtd.
327 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
329 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
332 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
334 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
335 sure how this was supposed to work.
336 (scm_async_click): don't send SCM_TICK_SIGNAL.
337 (scm_init_async): don't initialize %tick-thunk.
339 * the following change doesn't affect the Scheme interface:
340 gc-thunk is called at the end of garbage collection. however it's
341 no longer implemented by pretending it's a signal.
343 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
344 system async corresponding to scm_gc_thunk.
345 * async.h: declare scm_gc_async.
346 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
347 gc-thunk directly, instead of going through a signal handler.
348 (scm_gc_async): new variable, points to the GC system-async.
349 (scm_init_async): save the GC async as scm_gc_async instead
350 of using system_signal_asyncs.
351 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
353 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
355 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
356 Don't screw up if we're interrupted.
357 * Makefile.in: Regeneradet.
359 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
361 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
363 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
364 we're not using AM_INIT_GUILE_MODULE any more.
365 * Makefile.in: Reneregated.
367 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
369 Functions for finding variable bindings, grace à Tim Pierce.
370 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
371 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
373 Get 'make dist' to work again.
374 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
375 * Makefile.in: Regenerated, like a surry without a fringe on top.
377 Changes for reduced Guile distribution: one configure script,
379 * configure.in, configure: Removed.
380 * acconfig.h, acinclude.m4: Moved to parent directory, where the
381 real configure script lives.
382 * Makefile.in, scmconfig.h.in: Regenerated.
384 * init.c: #include "script.h", to get prototype for script.c's
387 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
389 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
390 scm_must_malloc, not raw malloc.
392 * script.c (scm_compile_shell_switches): Dyke out debugging output
395 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
397 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
399 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
400 system has them. Hope this is safe. Previously
401 sys/timeb.h was included if HAVE_FTIME was defined or if
402 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
403 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
405 * ioext.c (scm_setfileno): add missing third argument to
408 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
410 * eq.c (scm_equal_p): Correctly compare strings of different
411 varieties. (Thanks to Tim Pierce.)
413 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
415 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
416 #! block comment must occur on a line all by itself.
418 Move most of the guts of shell command processing into libguile,
419 so guile.c can be very small (and eventuallly auto-generated. (I
420 mean, generated mechanically, not self-generated. Hmm.))
421 * guile.c, script.c, script.h: New source files.
422 * init.c (scm_boot_guile_1): Call scm_init_script.
423 * libguile.h: #include "script.h".
424 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
425 targets, for new executable.
426 (libguile_la_SOURCES): Mention script.c.
427 (modinclude_HEADERS): Add script.h.
428 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
429 not dynamic linking is enabled. This is because we're generating
430 executables now. Move CY_AC_WITH_THREADS call after those, so the
431 values of cy_cv_threads_libs captures the libs chosen above.
432 * Makefile.in, configure, aclocal.m4: Regenerated.
434 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
435 We don't maintain this interface any more, and it just confuses
438 * alloca.c: #include <scmconfig.h>, not <config.h>.
439 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
440 it'll get included in disties.
442 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
444 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
445 be distributed, because they confuse people.
446 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
448 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
450 * configure.in: check for presence of gethostent (not present on
452 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
453 * configure, scmconfig.h.in: Regenerated.
455 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
457 * backtrace.c (scm_backtrace): Split message string across
458 newlines properly. GCC is more tolerant of this than other
461 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
463 Merge threads directory into libguile.
464 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
465 threads.h: New source files.
466 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
467 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
469 (modinclude_HEADERS): Add threads.h, coop-defs.h.
470 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
471 coop-threads.c.cygnus, coop-threads.h.cygnus.
472 * configure.in: If we're using threads, include threads.o in
474 * _scm.h, libguile.h: threads.h lives in this directory now.
475 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
476 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
477 currently used, but brought along for information's sake.
478 * ChangeLog-threads: log from old 'threads' directory.
479 * Makefile.in, configure: Rebuilt.
481 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>

488 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
490 Merge GH interface library into libguile.
491 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
492 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
493 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
494 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
496 (EXTRA_libguile_la_SOURCES): ... here.
497 (pkginclude_HEADERS): Add variable, to get gh.h installed.
498 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
499 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
500 New variables, describing how to build the gh test programs.
501 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
502 build the test programs, and we probably should have been linking
503 libguile.la against them all along, to support AIX shared libs.
504 Add cflags for threads to CFLAGS; add libs for threads to new
505 variable THREAD_LIBS, used in Makefile.am.
506 * ChangeLog-gh: log from old `gh' subdirectory.
507 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
509 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
511 * acconfig.h: Undo change of Apr 9; including the definition of
512 PACKAGE in the guile headers conflicts with applications' own

525 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
527 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
528 have S_IFSOCK. This is the case under Ultrix.
530 * posix.c (scm_status_exit_val, scm_status_exit_val,
531 scm_status_term_sig, scm_status_stop_sig): Modified to work with
532 Ultrix versions of WIFSTOPPED, etc., which assume that their
533 arguments are lvalues (hmm).
535 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
539 * throw.c: Doc fixes; rearranged.
541 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
543 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
545 * acconfig.h: Added entry for PACKAGE.
546 * scmconfig.h.in: Regenerated.
548 Changes to work with automake-1.1n, which has better libtool support.
549 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
550 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
552 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
554 * Makefile.in: Rebuild.

563 (bdtime2c, setzone, restorezone): new static procedures.
564 (scm_mktime, scm_strftime): use them.
565 (scm_strftime): don't call mktime before strftime. Use
566 filltime for return value.
567 (filltime): convert NULL zname to #f.
568 (scm_strptime): return a count of characters consumed, not
569 the remaining string.
571 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
573 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.

580 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
582 * stime.c (scm_init_stime): don't define ticks/sec.
583 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
584 return value problem and is still portable.)
586 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
588 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
589 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
590 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
591 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
592 cpp_err_symbols.c): Corresponding changes.
593 * Makefile.in: Regenerated.
595 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
597 * posix.c (scm_putenv): don't check HAVE_PUTENV.
598 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
599 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
600 * putenv.c: new file, from sh-utils 1.12.
602 * posix.c (scm_environ): use malloc in place of scm_must_malloc
603 since allocation isn't for Scheme objects.
604 (scm_putenv): copy strings before placing in the environment.
606 * stime.c (scm_current_time): throw an error if time returns -1,
607 instead of returning #f.
608 (scm_get_internal_real_time, scm_get_internal_real_time): use
609 scm_long2num for return value instead of SCM_MAKINUM.
611 * stime.h: prototypes updated.
613 * stime.c (scm_time_in_msec): apparently unused, deleted.
615 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
617 * configure.in: check for gettimeofday.
619 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
620 which may be more usefully portable than a gettimeofday interface.
622 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
624 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
626 * Makefile.in: Regenerated.
628 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
630 * stime.c (filltime): recovered static procedure.
631 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from

635 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
637 * posix.c (scm_mknod): split the mode argument into type and perms
638 arguments, like the extra fields returned by stat.
640 * fports.c (scm_pipob): set the close, free and print procedures.
641 (scm_close_pipe): new procedure.
643 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
644 define them in boot-9.scm
646 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
648 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
649 wan't defined. Don't include fd.h.
651 * Previously fd.h was regenerated whenever configure was run,
652 forcing a couple of files to be recompiled.
654 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
655 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
656 Check for _fileno as well as _file.
658 * ioext.c: don't fd.h.
659 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
662 * Change the stratigy for getting information about errno
663 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
664 generating lists of symbols during the build process, which will
665 not always work, include comprehensive lists in the distribution.
666 To help keep the lists up to date, the "check_signals" and
667 "check_errnos" make targets can be used.
669 * configure.in: don't check for a command to extract errno codes.
670 * Makefile.am: update file lists, remove errnos.list and errnos.c
671 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
672 check_errnos targets.
673 (CLEANFILES): remove errnos.c and errnos.list, add
674 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
675 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
676 * errnos.default: deleted.
677 * cpp_signal.c: new file.
678 * cpp_errno.c: renamed from errnos_get.c.
679 * cpp_err_symbols, cpp_sig_symbols: new files.
680 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
681 * error.c (scm_init_error): #include cpp_err_symbols instead of
683 * posix.c (scm_init_posix): don't intern signal symbols. #include
686 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
688 * strop.c (scm_i_index): allow the lower bound to be equal to the
689 length of the string, so a null string doesn't always give an error.
691 * posix.h: new prototypes.
692 * posix.c (scm_status_exit_val, scm_status_term_sig,
693 scm_status_stop_sig): new functions, as in scsh. They break down
694 process status values as returned by waitpid.
696 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
698 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
699 configure doesn't know about it.
701 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
703 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
705 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
706 which defines C variables with global linkage.
708 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
710 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
713 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
715 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
716 has time to check why this doesn't work well with continuations.
718 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
720 * Fix shell syntax error; some shells won't tolerate
721 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
723 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
725 * posix.c (scm_uname): throw an error if uname fails instead
728 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
730 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
733 * async.c (scm_ints_disabled): definition moved from error.c.
735 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
737 * acconfig.h: Removed PACKAGE.
739 * scmconfig.h.in: Regenerated.
741 * snarf.h: g++ says it's non-portable not to specify the first
742 argument in a varargs declaration. I introduced the first
743 argument by using preprocessor conditionals.
745 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
747 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
748 (scm_freopen): use RO string macros for filename and modes.
749 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
751 * posix.c (scm_getgrgid): simplify conversion of name to C string.
752 (scm_mknod): use RO string macros for path.
754 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
755 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
757 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
758 use SCM_ROSTRINGP and SCM_ROCHARS.

767 support for byte vectors.
769 * print.c (scm_iprin1): Limit number of vector elements printed
770 according to pstate->length.

774 * backtrace.c (scm_display_error_message): don't segv if message
777 * error.h: prototype for scm_error_scm.
779 * error.c (scm_error_scm): new procedure, reimplements scm-error
780 in C and uses scm_error.
782 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
784 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
785 pointer to the Scheme variable read-hash-procedures and intern it
786 in scm_init_read. Modify scm_read_hash_extend and
787 scm_get_hash_procedure to use the pointer.
789 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
791 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
792 (SCM_KEYWORD_STYLE): defined.
794 * read.c (scm_read_opts): add a keywords option. This isn't a
795 boolean option, in case someone wants to add support for DSSSL
797 Setup scm_keyword_prefix symbol.
798 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
800 I've left keyword support disabled by default, since it doesn't
801 seem to break the module system and it gives R4RS standard behaviour.
802 It can be reactivated with (read-set! keywords 'prefix).
804 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
806 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
807 before constructing arbiter.
809 * eval.c (scm_m_define): Bugfix: Check that the object is a
810 closure before setting the procedure property!
812 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
814 * ports.c: Removed `ungetc-char-ready?'.
816 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
818 * read.c (scm_init_read): intitialise scm_read_hash_procedures
819 (idea from Mikael: make it a pair so scm_permanent object only
821 (scm_read_hash_extend): don't call scm_permanent_object.
822 (ideas from Mikael): if chr is already in the list, replace its
823 procedure instead of appending it again. If proc is #f, remove
825 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
827 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
829 * gdbint.c (gdb_read): update scm_lreadr usage.
831 * load.h: update prototypes.
833 * load.c (scm_primitive_load, scm_read_and_eval_x,
834 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
836 * read.h: add prototype for scm_read_hash_extend. Change args for
839 * read.c (scm_read_hash_procedures): new variable.
840 (scm_read_hash_extend): new procedure.
841 (scm_get_hash_procedure): new procedure.
842 (scm_lreadr): use scm_get_hash_procedure instead of an argument
843 for extended # processing.
844 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
845 scm_read_token): remove case_i, sharp arguments. Change callers.
847 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
849 * read.h (SCM_N_READ_OPTIONS): increase to 3.
850 (SCM_CASE_INSENSITIVE_P): define.
852 * read.c: add case-insensitive option to scm_read_opts.
853 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
854 to determine whether to convert symbol case.
855 (default_case_i): definition removed.
856 * read.c (scm_read_token): if case_i, downcase ic before doing
859 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
861 * configure.in: Added configuration option `guile-debug'.
862 Configure with --enable-guile-debug if you want a bunch of extra
863 functions used for debugging when developing Guile.
865 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
867 * procs.c (make-cclo): New undocumented debugging procedure: Make
868 compiled closure with internal procedure PROC and length LENGTH.
869 Only compiled if GUILE_DEBUG is defined.
871 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
873 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
875 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.

880 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
882 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
883 with 3 or more args internally to the evaluator. This is mainly
884 because we don't want to pass entry and exit points of the
885 debug support twice, but it also seems to increase the speed of
886 the evaluator for such calls (e. g. (+ 1 2 3)).
888 * backtrace.c (scm_display_application): New procedure:
889 display-application; Set fancy printing parameters individually
890 for different types of display (backtrace, error, application).
891 (These should of course be customizable!)
893 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
894 clear the CHECK-flags.

898 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
900 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
902 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
903 from pairs with a GLOC in the car.
905 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
906 otherwise `symbol-hash' will behave badly.
907 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
908 we get segmentation fault!
910 * symbols.c: Added #include "weaks.h". New functions:
911 `builtin-bindings' and `builtin-weak-bindings'. (These will be
912 moved to an extraneous library when we split libguile.)
914 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
916 * filesys.c (scm_stat): stat now takes fport arguments too as
917 documented in the manual.
919 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
921 * debug.c (scm_single_step): Bugfix: Call continuation with
922 scm_call_continuation instead of throwing to it.
924 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
926 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
927 argument wasn't declared to be optional.
929 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
931 * stime.c (scm_init_stime): Add feature "current-time".
933 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
935 * throw.h: prototype for scm_exit_status.
936 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
937 args to derive an exit status. Allows (quit) to work from a
939 (scm_exit_status): new function.
942 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
944 * eval.c (scm_deval): Removed some old code.
945 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
947 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
950 * symbols.c (msymbolize): Bugfix: Must initialize property list to
953 * procs.c: Introduce the existent C function scm_thunk_p at the
954 Scheme level as well.
956 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
958 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
959 used from C to easily lookup the value of a symbol in the current
962 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
964 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
965 scm_init_unif in this file. This will also fix a previous problem
968 * configure.in: Added AM_MAINTAINER_MODE
970 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
972 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
975 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
977 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
978 source files that are not always included in libguile but should
979 have their dependencies calculated by automake. This variable is
980 recognized by automake, no further magic is needed.
981 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
982 to deal exclusively with *.lo files, as it seems. The *.o files
983 are built automatically when the corresponding *.lo file gets
986 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
988 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
991 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
993 * unif.c (scm_array_set_x): minor change to argument error checking.
995 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
997 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
998 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
999 They should only be included in the library at configure.in's
1001 (libguile_la_LDADD): Include the appropriate .lo files here.
1002 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
1003 so we know when to build them (and their .lo bretheren).
1004 * configure.in (LIBLOBJS): New substituted variable. We let
1005 configure decide which .o files to include in LIBOBJS, and then
1006 put the corresponding list of .lo files in LIBLOBJS. The latter
1007 is what we pass to libtool.
1008 * Makefile.in, configure: regenerated.
1010 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
1012 * symbols.c (scm_sysintern0): New function. Contains the core of
1013 old scm_sysintern but doesn't take a second value argument.
1014 (scm_sysintern): Now uses scm_sysintern0.
1015 (scm_sysintern_no_module_lookup): Renamed to
1016 scm_sysintern0_no_module_lookup and doesn't take a second value
1017 argument any longer.
1019 * symbols.h (scm_sysintern0: Added declaration.
1021 * options.c (scm_init_opts): Use scm_sysintern0 instead of
1022 scm_sysintern when interning option keys. Otherwise we risk
1023 destroying the values of already interned variables.
1025 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
1026 scheme-level boolean (use SCM_NFALSEP).
1028 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
1030 (scm_backtrace): New function. (C version of old function from
1031 boot-9.scm) Motivation: Make it possible to display backtraces
1032 without depending on boot-9.scm. (I'm uncertain if this
1033 motivation is good enough...)
1035 * root.h (scm_root_state): Add member the_last_stack_var.
1036 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
1038 * root.c (mark_root): Mark scm_the_last_stack_var.
1040 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
1043 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
1045 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
1046 1. mark_lazy_catch didn't mark the smob.
1047 2. Both functions above have standard variants:
1048 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
1049 free_lazy_catch --> scm_free0.
1051 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
1053 * throw.c (scm_internal_lazy_catch): New function.
1054 (scm_lazy_catch): Rewritten to use it.
1055 (scm_ithrow): Handle the new lazy catch representation.
1056 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
1057 that doesn't have a jmpbuf is a lazy catch clause.
1058 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
1059 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
1060 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
1062 (scm_init_throw): Register the new lazy-catch smob type.
1063 * throw.h (scm_internal_lazy_catch): decl for new function.
1065 * throw.c (scm_internal_catch): Doc fixes.
1067 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
1068 configure.in. Including this might cause problems if applications
1069 that link against libguile include their own copies of alloca, but
1070 if they're using autoconf, they should be adding libguile to LIBS
1071 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
1072 the copy in libguile, and things will be okay. (I think.)
1074 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1076 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
1078 strop.h: move prototypes too.
1080 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
1082 * posix.c (scm_init_posix): don't intern EINTR since it's now done
1085 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
1086 etc. I deleted them from filesys.c long ago, but didn't
1087 notice they were here too (although ineffective since
1088 sys/stat.h wasn't included).
1090 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
1092 * eval.c: Don't define alloca in GCC case. gcc will automatically
1093 use __builtin_alloca if appropriate.
1095 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1097 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
1098 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
1099 that values of automatic variables are preserved. See comments
1100 for safe_setjmp for details.
1102 Change from Thomas Morgan:
1103 * variable.c: Include eq.h.
1104 (var_equal): New function.
1105 (variable_smob): Use var_equal as the discriminator for variables.
1107 * throw.c (s_throw): Remove extraneous declaration.
1109 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
1110 * eval.c: Add necessary CPP cruft to support that.
1111 * configure, Makefile.in, scmconfig.h.in: regenerated.
1113 Change from Thomas Morgan:
1114 * procprop.c (scm_procedure_properties): Convert the Scheme
1115 boolean returned by scm_procedure_p into a C boolean before using
1116 it as a condition for SCM_ASSERT.
1117 (scm_procedure_property): Likewise.
1119 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
1120 indications of Unixness.
1123 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
1125 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
1127 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
1129 * read.c (scm_lreadr): use scm_misc_error to improve one of the
1130 "unknown # object" error messages.
1132 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
1133 (scm_i_index) and declare it static. Add a 'direction' argument
1134 to indicate what way the search should go.
1135 (scm_i_index): throw out-of-range error instead of wrong-type-arg
1137 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
1138 strop.h: remove scm_i_index, scm_i_rindex prototypes.
1140 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1142 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
1144 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
1145 to avoid clash with various scsh forks.
1147 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
1149 The following two changes (ramap.c, throw.c) are motivated by the
1150 apparent unportability of forward declarations of static arrays of
1151 the form `static foo bar[];'.
1153 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
1154 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
1156 * throw.c (scm_throw): Moved above scm_ithrow.
1158 * options.h: Removed the extern declarations of scm_yes_sym and
1159 scm_no_sym since these are static.
1161 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1163 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
1165 * Makefile.am: remove AWK=@AWK@.
1166 Add a rule for generating errnos.list.
1167 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
1169 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
1170 don't extract errnos, just set a variable (avoids the
1171 need to recompile error.c just because configure is run.)
1173 * unif.h: update prototypes.
1174 * unif.c (scm_uniform_array_read,write): change the offset and
1175 length arguments to start and end, for consistency.
1177 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
1179 * ioext.h: update prototypes.
1180 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
1181 scm_read_line_x, it's a more general procedure using an
1182 interface from scsh. read-line and read-line! are now defined
1184 Note that the new read-line trims the terminator
1185 by default, previously it was appended to the returned string. An
1186 optional argument specifies how to process the terminator (scsh
1187 compatible). For the old behaviour: (read-line port 'concat).
1188 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
1189 returns a pair, but is converted to multiple values if the scsh
1192 socket.h: update prototypes.
1193 * socket.c (scm_recvfrom): for consistency with other procedures,
1194 take start and end as separate optional arguments.
1195 (scm_recv, scm_recvfrom): don't allow the second argument
1196 to be a size, only a buffer. Change the scheme names to
1197 recv! and recvfrom!. Don't return the buffer.
1199 * ioext.h, posix.h: move prototypes too.
1200 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
1201 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
1202 "read.h" and "unif.h".
1203 * ioext.c: include "chars.h"
1205 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
1207 * dynl.c: The dynamic linking and module registration functions
1208 are now defined even when dynamic linking is not available for the
1209 host system. Some of their functionality can be done without
1210 dynamic linking; when it's really needed, they throw errors.
1212 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
1214 * configure.in: Only define DYNAMIC_LINKING when one of the system
1215 dependent functions is detected.
1216 * dynl.c (scm_dynamic_func): New function to get the address of a
1217 function in a dynamic object.
1218 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
1219 produced by scm_dynamic_func as the thing to call.
1221 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
1223 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
1224 (scm_register_module_xxx, scm_registered_modules,
1225 scm_clear_registered_modules): New functions.
1227 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
1229 * symbols.c (scm_sysintern): Renamed to
1230 scm_sysintern_no_module_lookup.
1231 (scm_sysintern): New function to take the place of the old
1232 scm_sysintern. It uses the current toplevel lookup closure to give
1233 the symbol its value. This is a temporary hack to put packages
1234 like gtcltk into their own module.
1235 (scm_can_use_top_level_lookup_closure_var): New variable to tell
1236 us whether `scm_top_level_lookup_closure_var' has been initialized
1238 * eval.c (scm_init_eval): Set it.
1240 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
1242 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
1243 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
1245 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
1247 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
1248 scm_sys_dup): deleted: FD capability will be added to other
1250 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
1251 scm_fd_free, fd_smob, scm_intern_fd.
1252 (scm_open): renamed from scm_sys_open. Return a port instead of
1253 an FD object. Make the mode argument optional.
1254 (scm_sys_create): deleted, it's just a special case of open.
1255 (scm_init_filesys): move interning of constants O_CREAT etc.,
1256 here (were previously using SCM_CONST_LONG macro).
1257 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
1259 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
1260 include "fports.h" and <stdio.h>
1261 (scm_stat, scm_select): don't support FD objects.
1263 * error.h: adjust scm_syserror_msg prototype.
1264 * error.c (scm_syserror_msg): take an extra argument for errno.
1265 Using the global value didn't always work, since it could be
1266 reset by procedure calls in the message or args arguments.
1268 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
1269 I don't understand why the check was there (and what about the
1272 * strop.c (scm_string_copy): allow shared substrings to be copied.
1274 * unif.h: corresponding change to prototypes.
1275 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
1276 recognize two new optional arguments: offset and length. Allow
1277 the port argument to be an integer (file descriptor, for scsh).
1278 Include <unistd.h> for "read" prototype.
1280 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
1282 * socket.c: don't include filesys.h.
1284 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
1286 * Makefile.am: add AWK=@AWK@ (?)
1288 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
1290 Add a rule to generate errnos.c from errnos.
1291 * error.c (scm_init_error): include errnos.c.
1292 * errnos_cnvt.awk: new file, converts the list of errno codes to
1294 * errnos_get.c: new file.
1295 * errnos.default: new file, contains errnos to try if they can't
1296 be extracted from errno.h.
1297 * configure.in: if using GCC, try and extract errno codes from
1301 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
1303 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
1304 * Makefile.am: Made libguile into a libtool library.
1305 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
1306 Set libtool_libs to indicate that libguile is a libtool library.
1307 See guile/ChangeLog for details.
1308 * .cvsignore: ignore "*.lo", the libtool library objects.
1310 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1312 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
1313 use htons in getservbyport argument.
1315 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
1317 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
1318 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
1321 * objprop.c (scm_object_property): No need to take the CDR of the
1322 value returned by scm_object_properties, since Aug 20 change.
1324 * configure.in: When checking for struct linger, #include
1325 <sys/types.h> as well as <sys/socket.h>. I've never known
1326 <sys/types.h> to cause any portability problems, and Solaris's
1327 <sys/socket.h> needs it.
1328 * configure: Rebuilt.
1330 I think the Sun compiler has chosen a perverse way to interpret
1331 ANSI declarations combined with K&R definitions. We'll
1332 appease it a little bit. But when it invades France, we fight.
1333 * print.c (scm_iprlist): Change 'tlr' argument to an int.
1334 * print.h (scm_iprlist): Here too.
1335 * numbers.c (scm_divbigdig): Change definition to match
1336 declaration in numbers.h.
1337 * unif.c (scm_makflo): Change definition to match declaration in
1340 * init.c (scm_boot_guile): Don't return the value of
1341 scm_boot_guile_1. This function doesn't return a value;
1342 scm_boot_guile_1 doesn't return a value (or return at all).
1344 * eval.c (unmemocopy): Add a semicolon to appease the Sun
1347 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
1348 compile. I have a feeling this function is a bad idea anyway ---
1349 one should always test for features, not systems.
1351 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
1352 semicolons. Only pure luck kept this from being noticed earlier.
1354 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
1356 * socket.c (scm_recvfrom): Added missing semicolon.
1358 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1360 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
1361 the buffer and start and end positions for scsh networking
1364 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
1366 * configure.in: Revert previous change to this file; the problem
1367 is due to transient automake weirdness.
1368 * configure: Rebuilt.
1370 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
1371 PLUGIN/guile.libs. configure generates the latter from the former.
1372 * Makefile.in: Rebuilt.
1374 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
1375 need this if we install scripts, like guile-snarf.
1376 * configure: Rebuilt.
1378 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1380 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
1382 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
1384 * socket.c (scm_addr_vector): fix faulty scm_listify.
1386 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
1388 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
1389 style block comment is no longer considered an error.
1391 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
1393 * PLUGIN/guile.libs.in: New file.
1394 * PLUGIN/guile.libs: Removed from repository.
1395 * configure.in: Create PLUGIN/guile.libs from
1396 PLUGIN/guile.libs.in. This is for including additonal libraries
1397 needed for dynamic linking.
1398 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
1399 instead of PLUGIN/guile.libs.
1401 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
1403 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
1405 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
1406 occurrences of the given element from the list, not just the
1407 first. This is how the Emacs Lisp functions behave, how the
1408 analogous Common Lisp functions behave, and (I believe) how the
1409 older Maclisp functions worked. I realize that this change may
1410 break code, but it seemed better to break it before the Guile
1413 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
1414 Their prototypes were already present in gc.h, but they weren't
1416 (scm_init_storage): Initialize scm_protects.
1417 * root.c (scm_protects): New element of scm_sys_protects.
1419 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
1421 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1423 * libguile.h: Added #include "libguile/net_db.h".
1425 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
1426 30 change. That file is only meant for communication between the
1427 configuration process and load.c. If code linked against libguile
1428 wants to get at the paths mentioned in libpath.h, it can call
1429 functions declared in load.h.
1431 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1433 * libguile.h: Removed #include "libguile/fdsocket.h"
1435 * net_db.c: Added #include <sys/socket.h>.
1437 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
1439 * filesys.c (scm_input_waiting_p): use select in preference to
1440 FIONREAD, since the latter doesn't detect EOF.
1441 Throw error if neither select nor FIONREAD available.
1443 * socket.c (scm_connect): take a port, not a fd object.
1444 (scm_fill_sockaddr): throw an error if fam is not recognised.
1445 (scm_bind): use scm_fill_sockaddr.
1446 (scm_listen): take a port, not a fd object.
1447 (scm_accept): take and return a port. return #f in the car if
1448 address can't be got
1449 (scm_sock_fd_to_port): new procedure.
1450 (scm_socket): use scm_sock_fd_to_port.
1451 (scm_addr_vector): throw error if unrecognised address type.
1452 take an extra argument with the calling procedure name.
1453 (scm_getsockname): take a port. return #f if address can't be got.
1454 (scm_getpeername): take a port. return #f if address can't be got.
1455 (scm_recvfrom): take a port. return #f for address component if can't
1457 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
1458 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
1460 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
1462 * throw.c (scm_internal_catch): Make body funcs and handler funcs
1463 use separate data pointers, to allow them to be designed
1464 independently and reused.
1465 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
1466 Renamed from catch_body, catch_handler, and uncaught_throw; made
1468 (struct scm_catch_body_data): Renamed from catch_body_data; moved
1470 (scm_catch): Use the above.
1471 (scm_throw): Don't bother printing a message for an uncaught
1472 throw; we establish a default handler in init.
1473 * throw.h (scm_internal_catch): Prototype updated.
1474 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
1476 (struct scm_body_thunk_data): New structure, used as data
1477 argument to scm_body_thunk.
1478 * init.c (struct main_func_closure): New structure, packaging up
1479 the data to pass to the user's main function.
1480 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
1481 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
1482 scm_internal_catch to establish a catch-all handler, using
1483 scm_handle_by_message. This replaces the special-case code in
1485 (invoke_main_func): Body function for scm_internal_catch; invoke
1486 the user's main function, using the main_func_closure pointer to
1487 decide what to pass it.
1488 * root.c (struct cwdr_body_data): Remove handler_proc member.
1489 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
1490 (cwdr_handler): Removed.
1492 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1494 * socket.h (SCM_P): update bind prototype.
1495 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
1496 include "feature.h".
1497 (scm_socket): return a port, not a file descriptor object.
1498 include "fports.h" and <unistd.h>
1499 (scm_bind): take a port, not a file descriptor object.
1500 take an extra argument for address args.
1502 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
1503 INADDR_NONE, INADDR_LOOPBACK.
1505 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1507 * init.c: include net_db.h and not fdsocket.h.
1508 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
1510 * Makefile.am: corresponding changes.
1511 * socket.h: renamed from fdsocket.h, fix names.
1512 * net_db.h: renamed from socket.h, fix names.
1513 * socket.c: renamed from fdsocket.c.
1514 remove _sys from procedure names.
1515 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
1516 add "socket" to features list.
1517 * net_db.c: renamed from socket.c.
1518 remove _sys from procedure names.
1519 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
1520 add "net-db" to features list.
1521 include "net_db.h". don't include <sys/socket.h> or
1524 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1526 * tags.h (scm_tags): Removed comma at end of last enumerator.
1528 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
1530 Don't use GCC extensions to allocate space for debugging frames.
1531 (Here he goes again! Why do we put up with this?!)
1532 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
1533 an scm_debug_info structure, not an in-line array of them. Add
1534 'info' member, to say how many vect elements we've used, for eval
1536 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
1537 a new variable debug_info_end to mark the end of vect, instead of
1538 the address of the 'info' pointer itself.
1539 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
1540 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
1541 (SCM_APPLY): Explicitly allocate space for debug.vect.
1542 * debug.c (scm_m_start_stack): Same, for vframe.vect.
1543 * stacks.c: Adjusted for new debug frame structure.
1544 (RELOC_INFO, RELOC_FRAME): New macros.
1545 (stack_depth, read_frames): Use them, and new scm_debug_frame
1546 element 'info', instead of magically knowing that eval frames have
1547 an info pointer sitting after vect.
1548 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
1550 (scm_init_stacks): Formatting tweaks.
1552 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
1554 Give GCC more control flow information, so it can be sure that
1555 variables aren't used uninitialized.
1556 * error.h (scm_error, scm_syserror, scm_syserror_msg,
1557 scm_sysmissing, scm_num_overflow, scm_out_of_range,
1558 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
1559 scm_misc_error): Tell GCC that these functions never return.
1560 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
1561 out the field type, call abort if SCM_ASSERT returns, to placate
1563 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
1564 scm_wta ever returns. We can't handle this case anyway, and this
1565 gives the optimizer more information.
1566 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
1567 scm_wta ever returns.
1569 In some cases, the code is fine, but GCC isn't smart enough to
1570 figure that out; this usually happens when one variable is only
1571 initialized and used when a particular condition holds true, and
1572 we know that condition will never change within a given invocation
1573 of the function. In this case, we simply initialize the variables
1574 to placate the compiler, hopefully to a value which will cause a
1575 crash if it is ever actually used.
1576 * print.c (scm_iprin1): Initialize mw_pos.
1577 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
1578 * throw.c (scm_ithrow): Initialize dynpair.
1579 * unif.c (scm_uniform_vector_ref): Initialize cra.
1580 * struct.c (init_struct): Initialize prot.
1581 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
1583 * strports.c (scm_eval_0str): Don't return uninitialized garbage
1584 if EXPR contains no expressions.
1586 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
1588 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
1589 cause an infinite loop (???). So much for the algebraic
1590 equivalency of variable-sized arrays and alloca...
1592 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
1594 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
1595 a SCM boolean, not a C boolean.
1597 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
1599 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
1600 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
1601 rules for raising scm_mtrigger. Previously, unfortunate but not
1602 unlikely circumstances could result in almost constant invokation
1603 of the gc. Now, this situations should be less likely, but they
1604 are not prevented completely.
1606 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
1608 * numbers.c (scm_fuck): Procedure removed; looks like old test
1610 * numbers.h: Prototype removed.
1612 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
1614 * debug.h (scm_debug_frame): Change `vect' member from an in-line
1615 array to a pointer, to match my Nov 21 change in eval.c.
1617 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1619 * libguile.h: Added #include "libguile/backtrace.h", #include
1620 "libguile/stacks.h".
1622 * strings.c (scm_string scm_make_string scm_string_ref
1623 scm_string_set_x scm_string_equal_p scm_string_append):
1624 Bugfix according to scm patch from Aubrey Jaffer:
1625 Corrected long-standing
1626 (not (eqv? (integer->char 128)
1627 (string-ref (make-string 1 (integer->char 128)) 0)))
1628 bug found by John Kozak <jk@noontide.demon.co.uk>.
1630 * strports.c, strports.h: Make scm_eval_0str return the value of
1631 the last expression evaluated (previously, it returned void).
1633 * strports.c, strports.h: New function: scm_read_0str. Does what
1636 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1638 * simpos.c (scm_getenv): return #f if string can't be found in the
1639 environment instead of throwing an exception, for compatibility
1640 with numerous other systems.
1642 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
1644 * Makefile.am (.c.x): Use guile-snarf.
1645 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1647 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1649 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1651 * backtrace.c (scm_display_error_message): Made non-static, and
1652 renamed from display_error_message.
1653 * backtrace.h (scm_display_error_message): Added extern decl.
1654 * throw.c (uncaught_throw): Use it to display the error message.
1656 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1658 * inet_aton.c: Use #if 0, not #ifdef 0.
1660 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1662 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1663 to convert the returned value.
1664 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1665 the offset argument.
1667 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1669 Add new interface to catch/throw, usable from C as well as
1671 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1672 (scm_internal_catch): New function, replaces...
1673 (scm_catch_apply): Deleted.
1674 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1675 mechanism which is a bit more code, but can be used nicely from C
1676 and implement the Scheme semantics as well.
1677 (scm_internal_catch): This is the replacement; it's named after
1678 the analogous function in Emacs.
1679 (scm_catch): Reimplemented in terms of the above.
1680 (struct catch_body_data, catch_body, catch_handler): New
1681 functions, used by scm_catch.
1682 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1683 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1684 support for new cwdr.
1686 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1689 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1691 * acconfig.h: Added DYNAMIC_LINKING symbol.
1692 * configure.in: Add option and checks for dynamic linking.
1693 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1694 dynl.h: New files for dynamic linking support.
1695 * Makefile.am (libguile_a_SOURCES):
1697 (modinclude_HEADERS): Added "dynl.h".
1698 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
1700 * init.c (scm_boot_guile_1): Call
1701 scm_init_dynamic_linking to initialize dynamic linking support.
1703 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
1705 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
1706 (as we Schemers say). It needs to be global, so that I can tweak
1707 it for the proper operation of unexec.
1708 (scm_boot_guile_1_live): New variable, see above.
1710 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
1712 * guile-snarf.sh: Removed.
1713 * PLUGIN/guile.libs: Added dependency for -lm.
1714 * acinclude.m4: Renamed from aclocal.m4.
1715 * PLUGIN/greet: Removed.
1716 * Makefile.am, aclocal.m4: New files.
1717 * configure.in: Updated for Automake.
1719 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
1721 * eval.c (scm_definedp): Use top_level_lookup_closure_var
1722 and not top_level_lookup_thunk_var.
1724 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
1726 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
1728 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
1730 * eval.c (scm_definedp): Incompatibly changed to be a builtin
1731 Scheme function, instead of syntax. Single argument is now a
1734 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1736 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1737 scm_ra_divide): Properly terminate statements passed as arguments
1738 to IVDEP macros. (Thanks to Bernard Urban.)
1740 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1741 with non-constant sizes. (Thanks to Bernard Urban.)
1743 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1745 It's an "eval closure", not an "eval thunk." A thunk is a
1746 function of no arguments.
1747 * root.h (struct scm_root_state): Renamed
1748 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1749 (scm_top_level_lookup_closure_var): Renamed from
1750 scm_top_level_lookup_thunk_var.
1751 * root.c (mark_root): Uses changed.
1752 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1753 * init.c (scm_start_stack): Uses changed.
1754 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1755 Change scheme-visible name to *top-level-lookup-closure* from
1756 *top-level-lookup-thunk*.
1758 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1760 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1761 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1763 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1765 * gc.c (struct scm_heap_seg_data): Doc fixes.
1767 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1768 sweeping. Then, prepend each segment's free cells to its
1769 freelist, rather than wiping out the old value. (Thanks to Marius
1772 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1773 scm_check_freelist, scm_debug_newcell): New functions and
1774 variables, for debugging freelist problems.
1775 * pairs.h (SCM_NEWCELL): New debugging version added.
1776 * gc.h (scm_debug_newcell): Added extern declaration, used by
1777 debugging version of SCM_NEWCELL.
1779 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1781 On some systems <libc.h> conflicts with <unistd.h>, and should not
1782 be #included at all.
1783 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1784 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1785 * configure.in: Call it.
1786 * posix.c, filesys.c: Use its results to decide whether or not to
1788 * configure, scmconfig.h.in: Rebuilt with autoconf and
1791 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1793 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1794 pointer to the stdio stream before calling scm_setbuf0, so the
1795 latter will be able to retrieve it. I'm surprised this didn't
1796 segfault earlier. (Thanks to Christopher Lee.)
1798 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1800 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1803 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1805 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1806 number of stack narrowing specifier pairs. The first specifier in
1807 a pair controls inner border, the second the outer border. A
1808 number means cut that number of frames, a procedure object means
1809 cut until that object is found in operator position in a frame.
1811 * root.c (cwdr): Bugfix.
1813 * read.c: Recording of positions disabled by default.
1815 * procs.c (scm_closure_p): New function.
1817 * posix.c (scm_tmpnam): New function.
1819 * load.c: Added #include "throw.h".
1820 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1823 * load.c, load.h (scm_read_and_eval_x): New function.
1825 * eval.c: Renamed debug option "deval" to "debug".
1827 (scm_eval_x): `eval!' is no longer accessible from the scheme
1828 level. Motivation: We can't allow operations which introduce
1829 glocs into the scheme level. Guile's type system can't handle
1830 these as data. Use `eval' or `read-and-eval!' as replacement.
1832 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1833 SCM_CONSP since this is a macro!; Set vframe.prev to
1834 scm_last_debug_frame instead of 0. In this way we can look
1835 "above" the virtual start stack frame if we wish.
1836 (scm_debug_hang): New function: Useful for debugging Guile in
1837 certain tricky situations. Will probably be removed later...
1839 * debug.h: Changed semantics of debug option "backtrace". This
1840 option now only indicates whether we want automatic backtrace at
1843 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1845 * ports.c: #include "filesys.h"
1846 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1848 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1849 Motivation: This is system specific code which is related to file
1850 I/O. It also may use select. Added code by Gary Houston to
1851 detect presence of character in stdio buffers.
1853 * libguile.h: #include "libguile/libpath.h"
1855 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1856 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1857 SCM_SITE_DIR; Install libpath.h among the other include files.
1859 * load.c, load.h (scm_sys_package_data_dir): New function.
1861 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1863 * stacks.h: Bugfix: Don't use tail-array length field as stack
1864 length field! This screwed GC.
1866 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1868 * _scm.h: Added #ifndef around definition of macros min and max.
1870 * __scm.h: Added hooks for threads to plugin to in ints protection
1871 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1872 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1873 the main code in these macros duplicated and spread over multiple
1874 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1875 SCM_THREAD_SWITCHING_CODE.
1877 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1879 * snarf.h: New file.
1880 * guile-snarf.sh: New file.
1881 * Makefile.in (inner_h_files): Added snarf.h
1882 (ancillary, install, uninstall, distclean): Added actions for
1884 (.c.x): Use guile-snarf.
1885 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1886 (gen_c_files): Note that these depend on guile-snarf.
1887 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1888 now in "snarf.h". Added #include "snarf.h" to get them.
1889 * libguile.h: Added #include "snarf.h".
1890 (Patches applied and tweaked by Jim Blandy.)
1892 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1894 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1895 standards suggest against providing prototypes for system
1896 functions. Thanks to Greg Troxel.
1898 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1900 * strports.c (scm_eval_0str): New function.
1901 #include "read.h", to get prototype for scm_read.
1902 * Makefile.in (strports.o): Update dependencies.
1903 * strports.h: New prototype.
1905 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1906 scheme name from "int?" to "integer?". It seems to do the job.
1907 * numbers.h: Rename prototype too.
1908 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1911 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1912 scm_num_eq_p): Rename these according to R4RS conventions: call
1913 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1914 to making libguile R4RS compliant without ice-9...
1916 * load.c (scm_sys_search_load_path): Search for files under all
1917 extensions listed in the %load-extensions variable. If FILENAME
1918 is absolute, return it unchanged, without searching the load path.
1919 (scm_loc_load_extensions): New variable, pointing to
1920 %load-extensions' value cell.
1921 (scm_init_load): Initialize it, and the value it points to.
1922 (scm_primitive_load_path): Improve error reporting.
1924 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1925 of new Scheme variable %load-hook.
1926 (scm_primitive_load): Apply %load-hook to filename.
1928 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1930 * configure.in: add tests for figuring out whether buffered data
1931 is available in a FILE structure, which is needed by char-ready.
1933 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1936 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1937 exceptions using misc_error instead of syserror. It seems a bit
1938 odd to throw an exception if a string can't be found in the
1939 environment, but it's consistent with open-file, stat etc.
1940 (simpos.h): remove sys_ from getenv.
1942 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1943 occurs, throw an error instead of returning errno. Return value
1945 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1947 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1949 * filesys.c (scm_stat2scm): derive file type and permissions from
1950 the stat mode and append them to the returned vector.
1951 There isn't much overhead in doing this and it avoids the need to
1952 work with S_IRUSR et al. in Scheme.
1953 Define symbols scm_sym_regular etc.
1954 (scm_init_filesys): don't intern S_IRUSR etc.
1956 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1957 and s_primitive_load_path.
1959 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1961 * error.h: don't declare error symbols. prototype for scm_misc_error.
1963 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1966 * error.c: use SCM_SYMBOL to set up error keys.
1967 scm_misc_error: new procedure.
1969 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1971 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1972 between `#!' and `!#' is ignored.
1973 (skip_scsh_block_comment): New function.
1975 * feature.c (scm_set_program_arguments): New argument, FIRST.
1976 * feature.h: Update prototype.
1977 * init.c (scm_boot_guile_1): Pass new argument to
1978 scm_set_program_arguments.
1980 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1982 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1983 (scm_boot_guile): Call scm_set_program_arguments here, later than
1984 the old initialization.
1986 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1987 initialization procedure.
1988 - Delete in, out, err arguments; there are other perfectly good
1989 ways to override these when desired.
1990 - Delete result argument; this function shouldn't ever return.
1991 - Rename init_func argument to main_func, for less confusion.
1992 - Delete boot_cmd argument; main_func is more general.
1993 -Add 'closure' argument, to help people pass data to main_func
1994 without resorting to global variables.
1995 - Abort if reentered; don't bother returning an error code.
1996 - Call scm_init_standard_ports to set up the default/current
1997 standard ports; no need to pass them to scm_start_stack.
1998 - Remove code to evaluate the boot_cmd, and start the repl; let
1999 the user do something like that in main_func if they want.
2000 - Remove code to package up a return value; main_func can do any
2002 - Call exit (0), instead of returning.
2003 (scm_start_stack): Don't initialize the I/O ports here; that's
2004 weird. Delete in, out, err arguments. Move guts to
2005 scm_init_standard_ports, scm_stdio_to_port.
2006 (scm_init_standard_ports): New function, to set up current and
2007 default standard ports.
2008 (scm_start_stack, scm_restart_stack): Make these static.
2009 * init.h (scm_boot_guile): Adjust declaration.
2010 (scm_start_stack, scm_restart_stack): Remove externally
2011 visible declarations for these.
2012 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
2014 * fports.c (scm_stdio_to_port): New function. Its guts used to be
2015 written out several times in scm_start_stack.
2016 * fports.h: New declaration for the above.
2018 * feature.c (scm_set_program_arguments): New function.
2019 * feature.h: New declaration for the above.
2021 * ports.c: Formatting tweak.
2023 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
2025 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
2026 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
2027 for obtaining the address of a car or cdr field. Motivation:
2028 &SCM_CXR make assumptions about the internal structure of the
2031 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
2032 Motivation: see SCM_CXRLOC.
2034 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
2035 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
2036 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
2037 Motivation: Safer use. Some other macros are defined in terms of
2038 these operations. If these are defined using the SCM_SETCXR
2039 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
2040 to inefficiency and an <e1> with side-effects could potentially
2041 break. Also, these particular operations are heavily utilized in
2042 the garbage collector. In unoptimized code there will be a
2045 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
2046 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
2047 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
2048 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
2049 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
2050 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
2051 vports.c: Cleaned up use of pairs: Don't make any special
2052 assumptions about the internal structure of selectors and
2053 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
2054 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
2055 (Among other things, this change makes it easier to build Guile
2056 with certain compilers which have problems with casted lvalues.)
2058 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2060 * stacks.c: Improve selection of relevant stack frames when making
2061 a stack object. Introduce one level of indirection in the stack
2062 object to make it possible to "narrow" to a certain region of the
2063 stack. This facilitates making use of more clever algorithms (not
2064 implemented) for selecting relevant frames and gives a cleaner
2065 design since selection of frames can be done independently of
2066 extraction of frames from the real stack.
2067 (scm_stack_id): Also take #t as argument which means look at
2070 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
2071 Turn n_tail into an integer directly representing current number
2072 of frames in stack. Add field tail.
2074 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
2076 * debug.c (scm_make_memoized): Made it available at scheme level.
2077 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
2078 SCM_NIMP before applying heavier predicates in argument checking.
2079 (scm_local_eval): Also take memoized object as argument.
2081 * backtrace.c (scm_display_error): Just a safety measure: Stacks
2082 aren't created with zero length, but should such a strange
2083 creature suddenly turn up...
2085 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
2087 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
2088 `del', for the sake of C++ compilers. (Patch applied by JimB.)
2090 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
2092 * variable.c (scm_make_variable): Make the name hint optional, as
2094 (anonymous_variable_sym): Renamed from variable_sym. All uses
2097 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
2098 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
2099 of scm_primitive_load_path was also changed to
2100 "primitive-load-path", from "%try-load-path". Callers changed.
2101 We'd like to respect the convention that a function named
2102 "try-mumble" should behave just like the function called "mumble",
2103 but return #f instead of signalling some error.
2104 * load.h: Rename prototypes.
2106 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2108 * print.c (make_print_state, grow_print_state), print.h: Modified
2109 the print state representation: Don't use a tail array for
2110 recording of circular references. Resizing of the print state
2111 structure invalidates the print state pointer. To avoid passing
2112 around an indirect print state reference to all printing
2113 functions, we instead let the print state reference a resizable
2116 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2118 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
2119 Don't crash when passed an improper list terminated by a
2120 non-immediate value.
2122 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
2124 Allocate data for structures on an eight-byte boundary, as
2125 required by the tagging system.
2126 * struct.c (alloc_struct): New function.
2127 (scm_make_struct, scm_make_vtable_vtable): Call it.
2128 * struct.h (scm_struct_n_extra_words): Bump to 3.
2129 (scm_struct_i_ptr): New "field".
2130 * gc.c (scm_gc_sweep): When we need to free the data, use the
2131 information stored by alloc_struct to find the beginning of the
2132 block allocated to the structure, so we can free it.
2134 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2136 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
2139 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
2140 (scm_debug_info): New member: id.
2142 * stacks.c: Stacks are now represented as structs; Stacks have an
2143 id given to them by `start-stack'.
2144 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
2146 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
2147 Changed stack representation.
2149 * debug.c (scm_procedure_name): Try procedure property `name' for
2150 compiled closures aswell.
2152 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
2154 * eval.c: scm_i_name moved to gsubr.c
2155 (scm_m_define): Record names of all kinds of procedure
2156 objects. (Earlier, only closures were recorded.)
2158 * procprop.h: Added declaration of scm_i_name.
2160 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
2161 (scm_make_gsubr): Record names of compiled closures.
2163 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2165 * debug.c, debug.h: Removed obsolete code.
2167 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
2168 stacks.c: Renamed regs --> scm_contregs.
2170 * print.c (scm_free_print_state): Cleanup print state before
2171 returning it to pool. It is better to do it here than in
2172 scm_prin1 since scm_prin1 is called often.
2174 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
2175 s_set_source_property_x): Check that first argument is a pair or a
2178 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
2179 scm_i_line, scm_i_column and scm_i_breakpoint global.
2181 * init.c: Added #include "backtrace.h" and #include "stacks.h".
2182 (scm_boot_guile_1): Added calls to scm_init_backtrace and
2185 * debug.h: Added debug object smob declaration and macro
2188 * configure.in: Build with backtrace.o and stacks.o if debug
2191 * Makefile.in: Added entries for new files: backtrace.c,
2192 backtrace.h, stacks.c and stacks.h.
2194 * symbols.c (scm_sym2ovcell): Fixed documentation.
2196 * _scm.h (min, max): Added.
2198 * async.c: Moved `min' macro to _scm.h.
2200 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
2201 SCM_BACKTRACE_INDENT.
2203 * eval.c: Added new debug options `maxdepth' and `indent'.
2205 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
2207 * print.h: Added selector SCM_PRINT_STATE.
2209 * print.c: New functions: scm_make_print_state,
2210 scm_free_print_state.
2212 * print.h: Added declarations for scm_make_print_state,
2213 scm_free_print_state.
2215 * debug.c (scm_m_start_stack): New acro.
2217 * debug.h: Small cleanup.
2219 * init.c (scm_boot_guile_1): Moved scm_init_debug below
2222 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

2242 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
2243 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
2244 declare functions with prototypes. (Patch thanks to Marius
2247 More prototype-related changes from Marius Vollmer:
2248 * gdb_interface.h: Wrapped header file in #ifdef/#endif
2249 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
2250 * ports.h (ptobfuns): Added prototypes. This means some casting in
2252 * fports.c: Added casts for initializations, since the functions
2253 are defined to take FILE * as their stream argument, not SCM.
2254 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
2255 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
2256 to `char *str_data' to conform to prototype.
2258 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2260 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
2262 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
2264 * stime.c, stime.h: use SCM_P method.
2266 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2268 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
2269 be given at least two arguments. Insist that lst's last element
2270 be a list, but don't make any requirements of its predecessors.
2272 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2274 * eval.c (scm_nconc2last): Revert last change; there seems to be
2275 other stuff going on here.
2277 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2279 * eval.c (scm_nconc2last): Make sure that each element of lst
2280 (which is a list of argument lists, except for the tail) is a
2281 proper list, i.e., finite and terminated by '().
2283 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2285 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
2288 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
2289 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
2292 * vectors.c (scm_make_vector): Fill vectors with the undefined
2293 value, to help make Guile Scheme code more portable to other
2296 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
2297 * symbols.h, tags.h: Doc fixes.
2299 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
2301 * async.c (scm_take_signal): Doc fixes.
2303 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
2305 * numbers.c (scm_divbigint): When the remainder is zero, we don't
2306 want to subtract it from the modulus; we just want to leave it
2309 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
2311 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
2314 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
2316 * throw.c (scm_catch_apply): Finished implementation of
2319 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2321 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
2323 (scm_init_filesys): set "i/o-extensions" feature.
2326 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
2328 * Makefile.in (root.o): Correct dependencies.
2330 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
2332 * Makefile.in: Added dependency entry for root.o.
2334 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
2335 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
2337 * init.c (scm_start_stack): Set initial root continuation number
2340 * procs.c: New function: scm_thunk_p.
2342 * procs.h: Added declarations of scm_thunk_p.
2344 * root.c: Renamed `call-with-new-root' -->
2345 `call-with-dynamic-root'.
2346 (cwdr): Removed allocation of new root state. This should be done
2347 separately by use of scm_make_root.
2348 (scm_apply_with_dynamic_root): New function: Does what it
2349 sounds like. Needed when spawning threads.
2351 * root.h: Added member last_debug_frame to root state.
2352 Added #include "libguile/debug.h"
2354 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
2355 arguments. The motivation is that code in root.c needs catch
2356 functionality, and we want to avoid code duplication.
2357 New functions: scm_catch, scm_lazy_catch. These are wrappers for
2358 scm_catch_apply. scm_lazy_catch is intended to introduce catch
2359 handlers that run without popping the stack into the dynwind
2362 * throw.h: Added prototypes for scm_catch_apply and
2365 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2367 * root.h (scm_root, scm_set_root): Decouple thread support details
2368 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
2369 SCM_SET_THREAD_LOCAL_DATA.
2371 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
2372 and tortoise scanning loop.
2374 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
2376 * Makefile.in: Rebuild dependencies.
2378 * libguile.h: #include "libguile/print.h" before "smob.h", since
2379 the latter uses the print_state structure.
2381 * throw.c (scm_ithrow): Use the correct variable when checking to
2382 see if a given element of scm_dynwinds is a valid catch.
2384 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
2385 structure, abort; don't just silently ignore the garbage.
2387 * _scm.h: #include "print.h" here, since it seems to be used just
2389 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
2390 strports.c, unif.h: Don't #include "print.h".
2392 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2394 * feature.h (scm_loc_features): Removed external declaration.
2395 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
2397 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2399 * feature.c (scm_init_feature): Added threads feature (needs to be
2400 initialized here, since features doesn't exist when
2401 scm_init_threads is called).
2403 * libguile.h: Added #include "libguile/../threads/threads.h".
2404 (This is a kludge to get thread support working. This should be
2407 * configure.in, acconfig.h: Added flags for thread support.
2409 * scmsigs.c: Define `signal' to be `pthread_signal' if using
2412 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
2413 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
2416 * _scm.h: Added conditional #include "threads.h"
2418 * __scm.h (SCM_ASYNC_TICK): Added call to macro
2419 SCM_THREADS_SWITCHING_CODE.
2421 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
2422 allocate the basic dynamic root object.
2423 (scm_boot_guile): Added call to scm_init_root.
2425 * root.c, root.h: Added root smob.
2426 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
2427 functions: Implements dynamic roots mostly according to spec in
2428 SCM manual. Main difference is that the second argument is a
2429 throw handler rather than an error "thunk".
2431 * root.h: Added declaration of scm_init_root.
2433 * root.c: Added #include "genio.h", #include "smob.h", #include
2434 "pairs.h", #include "throw.h", #include "dynwind.h", #include
2436 (scm_init_root): Added #include "root.x".
2438 * throw.c: Added #include "stackchk.h"
2439 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
2440 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
2441 can be used in scm_call_with_new_root; Added reenabling of stack
2442 checking when catching a throw.
2444 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
2446 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
2448 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
2449 element is not found, as per R4RS.
2451 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2453 * list.c: Doc fixes throughout.
2455 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2457 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
2458 declare the char * to be const. Avoids a warning in rgx.c.
2460 * ports.h: spelling fix.
2462 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
2465 * load.c (scm_sys_try_load_path): throw an error if file not found
2466 (like it says it in NEWS).
2468 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2470 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
2471 PROPS slot to '(), not #f; it's an empty alist.
2473 * throw.h, throw.c: Use SCM_P instead of #if hair.
2475 Remove special support for uncaught throws; see throw.c for
2477 * throw.c (uncaught_throw): New function.
2478 (scm_ithrow): Call uncaught_throw if we don't find a throw
2479 target; don't mess with scm_bad_throw_vcell.
2480 (scm_bad_throw_vcell): Variable deleted.
2481 (scm_init_throw): Don't initialize it.
2483 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
2486 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2488 * numbers.c (scm_istr2int): If the number is short (as most
2489 numbers are), just call scm_small_istr2int to deal with it.
2490 (scm_small_istr2int): New function, created by un-#ifdefing the
2491 non-bignum version of scm_istr2int and renaming it.
2493 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
2495 * load.c (scm_sys_try_load): don't check whether value returned
2496 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
2497 Change the Scheme name from %try-load to primitive-load.
2499 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
2500 Can avoid passing a message, allowing it to be derived in the
2501 error handler (e.g., if we want to throw to the key both from
2504 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
2506 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
2507 references now have a new appearance which is more compact and
2508 also gives a clue about what the target of the reference is.
2509 By setting parameters in the print state, more fancy printing can
2510 be achieved. This is used by the (not yet commited) backtrace
2513 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
2515 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
2518 * print.c: Added #include "struct.h". Removed function
2521 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
2522 scm_iprin1. Removed prototype for scm_prlist.
2524 * arbiters.c (prinarb),
2525 async.c (print_async),
2526 debug.c (prindebugobj, prinmemoized),
2527 eval.c (prinprom, prinmacro),
2528 filesys.c (scm_fd_print, scm_dir_print),
2530 mallocs.c (prinmalloc),
2531 numbers.c, numbers.h (scm_floprint, scm_bigprint),
2532 smob.h (scm_smobfuns),
2533 srcprop.c (prinsrcprops),
2535 unif.c, unif.h (scm_raprin1, rapr1),
2536 variable.c (prin_var): Changed argument `int writing' to
2537 `scm_print_state *pstate'.
2539 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
2540 that it will be called before scm_init_print.
2542 * print.c (scm_prin1): Print states are now allocated when calling
2543 scm_prin1 and then passed around to all printing functions as an
2544 argument. A cache `print_state_pool' enables reuse of print
2546 (scm_make_print_state): New function.
2547 (scm_iprin1): Adaption to print states.
2548 (scm_iprlist): An initial "hare and tortoise" scan brings down
2549 time complexity to O (depth * N). (Better time complexity will be
2550 achieved when the printing code is completely rewritten.)
2552 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2554 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
2555 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
2556 it gets done whether or not the cache variable has a value.
2558 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2560 Distinguish #f and ().
2561 * __scm.h: #undef SICP.
2562 * pairs.h (SCM_EOL): Delete this definition, equating it with
2564 * tags.h (SCM_EOL): Give it a new definition here; I think I found
2565 the value it used to have. Doc fixes, too.
2567 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
2569 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
2570 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
2571 Lord's implementation of structs, allowing for tail arrays as
2572 described in the manual. Also fixed some bugs. (Both the interface
2573 and the implementation should be improved.)
2575 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
2577 * print.c, print.h: Closures now print like #<procedure foo (x)>.
2578 People who whish to see the source can do `(print-enable 'source)'.
2579 Removed #ifdef DEBUG_EXTENSIONS.
2581 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2583 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
2584 integer (assuming for now accepting an integer is a good thing).
2586 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2587 %S will be used instead for write'ing arguments.
2589 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2590 asserts. fix a few other asserts.
2591 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2592 scm_uniform_vector_ref, scm_array_set_x,
2593 scm_dimensions_to_unform_array): change args in
2594 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2595 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2596 scm_substring_fill_x): likewise.
2597 gsubr.c (scm_gsubr_apply): likewise.
2598 eval.c (SCM_APPLY): likewise.
2600 * eval.c (4 places): replace scm_everr with lgh_error or
2603 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2604 scm_memory_error): new procedures.
2605 scm_everr: deleted. can use scm_wta, dropping first two args.
2606 scm_error: convert NULL subr to SCM_BOOL_F.
2608 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2611 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2614 * error.c, error.h: new error keys: scm_arg_type_key,
2615 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2617 scm_wta: reimplement using lgh_error instead of scm_everr.
2619 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2621 * gdbint.c: scm_lread now has one more argument.
2623 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2624 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2625 loading source from non-file ports, which, e. g., happens when
2626 using the Emacs interface).
2628 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2631 * read.c: Added code for recording of positions of source code
2632 expressions; New functions: recsexpr, scm_lreadrecparen;
2633 _scm_make_srcprops --> scm_make_srcprops
2634 (scm_flush_ws): Removed updating of positions counters. This work
2635 is already done by scm_gen_getc
2637 * read.h: Added prototype for scm_lreadrecparen
2639 * print.c: Added #include "alist.h"
2641 * eval.c: Added #include "hash.h"
2643 * eq.c: Added #include "ramap.h"
2645 * options.c: Documentation fixes.
2647 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
2648 (scm_init_srcprop): Adjusted size of initial source-whash. Name
2649 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2650 --> scm_make_srcprops
2652 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2653 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2654 function calls in the definition of the whash access macros.
2656 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2658 * init.c (scm_boot_guile): Add level of indirection to
2659 scm_boot_guile_1() to ensure that stack base pointer is properly
2660 initialized. There was no guarantee that variable i was the
2661 highest/lowest variable on stack (i.e. the call frame of
2662 scm_boot_guile was not completely protected from gc).
2664 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2666 * ports.h (scm_port_table): put back file_name, it will be used to
2667 support debugging. Undo related changes in fports.c, ioext.c,
2670 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2672 * ports.h (scm_port_table): remove file_name member for now, it seems
2674 * fports.c (scm_open_file): don't set file_name in PTAB.
2675 (prinfport): don't use file_name in PTAB.
2676 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2677 * ports.c (scm_add_to_port_table): don't intialize file_name.
2678 (scm_port_file_name): remove for now.
2679 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2681 * fports.h (scm_mkfile): prototype deleted.
2682 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2684 * debug.c, unif.c: use scm_out_of_range instead of
2685 wta for range errors (ASSERT still needs work).
2687 * error.c, error.h (scm_out_of_range): new procedure.
2689 * error.c, error.h (scm_out_of_range_key): new key.
2691 * posix.c (scm_sync): #else was missing.
2693 * error.c, error.h: append _key to names scm_num_overflow and
2696 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2697 of consing an empty list.
2698 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2699 of macros, saves code and string space.
2700 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2701 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2702 lower case. Rename scm_syserror_m to scm_syserror_msg.
2703 error.h: prototypes for new procedures.
2705 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2707 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2709 * error.c, error.h: setup scm_num_overflow key.
2711 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2712 Remove definition of SCM_OVSCM_FLOW.
2714 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2716 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2717 explicit message and args.
2719 * error.c, error.h, __scm.h: change system_error_sym to
2722 * error.c (system_error_sym): remove leading %% from the Scheme name
2725 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2727 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2729 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2730 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2731 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2732 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2733 renamed. (These were introduced by unsupervised name
2736 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2738 * print.c: Added code for detection of circular references during
2739 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2740 a hook for printing of closures (accessible via print options).
2741 This leads to a split of calls to scm_iprin1 into two classes:
2742 elementary print operations (e. g. the code which prints a smob)
2743 still use scm_iprin1 while top level calls (like scm_display) use
2744 scm_prin1. scm_prin1 begins by clearing the data structure used
2745 to record reference information.
2747 * print.h: Added declarations of scm_prin1 and scm_prlist.
2749 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2751 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2753 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2755 * error.c (err_head): scm_iprin1 --> scm_prin1
2757 * debug.c: Adjusted header comment.
2761 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2763 * strerror.c: Doc fix.
2765 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2767 * gdbint.c (gdb_read): Now possible to run during GC.
2768 (unmark_port, remark_port): New functions.
2770 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2772 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2773 of allocating a new string object. Also, increase size by
2774 the factor 2 instead of 1.5.
2776 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2778 * __scm.h (SCM_P): Corrected to run under traditional C.
2780 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2783 * async.c: Calls to scm_sysintern corrected.
2785 * async.h (scm_async_clock): Redundant declaration removed.
2787 * continuations.c (scm_dynthrow): Redundant declaration removed.
2789 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2790 Definition typos corrected.
2792 * debug.h: Missing declarations of functions in debug.c added
2795 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2796 Missing declarations to functions in eval.c added.
2798 * filesys.c: Possibly uninitialized variable rv.
2800 * gc.h (scm_object_addr, scm_unhash_name): Missing
2801 declarations of functions defined in gc.c added.
2803 * genio.c: Possible typos str_data -> wstr_data. ???
2805 * genio.c: Possibly unintended shadowing of local variable
2806 `int c' (gotos out of scope of inner `c'). ???
2808 * init.c: Uninitialized `SCM last' may be used.
2810 * ioext.h: (scm_sys_isatty_p): Typo.
2812 * list.h (scm_list_head): Missing prototype for function in
2815 * numbers.c (scm_two_doubles): Changed from extern to static
2816 (is used only within numbers.c).
2818 * numbers.h: Repeated declarations removed.
2820 * ports.h (scm_close_all_ports_except): Declaration for the
2821 function defined in ports.c added.
2823 * posix.h: Missing declarations added.
2825 * procs.h (scm_make_subr_opt): Missing declaration added.
2827 * socket.h (scm_sys_gethost): Missing declaration added.
2829 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2831 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2832 Missing declarations added.
2834 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2836 * struct.c: Uninitialized variable `SCM answer' may be used.
2838 * unif.c (l2ra): Declaration prototype.
2840 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2841 defined in ramap.c).
2843 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2844 Redundant declarations removed (they are in ramap.h).
2846 * variable.h (scm_make_udvariable,
2847 scm_make_undefined_variable): Declaration corrected to
2848 correspond variable.c.
2850 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2851 Missing declarations added.
2853 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2855 * Makefile.in (distclean): Don't forget to delete fd.h.
2857 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2859 * fd.h.in, tags.h: Trivial cleanups.
2861 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2862 marksweep.h just declared functions from gc.c.
2863 * gc.h, libguile.h: Don't #include "marksweep.h".
2864 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2865 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2866 dependencies updated.
2868 * libguile.h: Don't #include "files.h"; it's been deleted.
2870 * files.c (scm_sys_delete_file): Moved to filesys.c.
2871 File is now empty; deleted.
2873 * filesys.c: scm_sys_delete_file is now here. Remove
2874 #if's; they seem to rely on remnants of an old portability
2875 regimen. If the problems come up again, solve them properly,
2876 using autoconf. Specifically: Don't test M_SYSV, and #define
2877 remove to be unlink if it's #defined; don't use remove just
2878 because HAVE_STDC_HEADERS is #defined.
2879 * filesys.h: Add declarations for scm_sys_delete_file.
2880 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2881 files.o, files.h, files.c, and files.x.
2882 * init.c: Don't #include "files.h", and don't call scm_init_files.
2884 Use SCM_P instead of PROTO; the latter intrudes on the user's
2886 * params.h: Deleted; definition of SCM_P moved to...
2887 * __scm.h: ... here, where it replaces PROTO macro.
2888 * libguile.h, smob.h: Don't #include "params.h".
2889 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2890 smob.h: Fix prototypes accordingly.
2891 * Makefile.in: Update dependencies.
2892 (inner_h_files): Remove params.h.
2894 * gc.c: #include "gc.h"; every module should include its header,
2895 to let the compiler cross-check the declarations against the
2898 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2899 simpos.h: #include "libguile/__scm.h".
2901 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2903 * init.c: Don't forget to #include smob.h and init.h.
2904 * Makefile.in: Dependencies updated.
2906 * smob.h: Use PROTO instead of #if __STDC__.
2908 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2910 * __scm.h: Doc fixes.
2912 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2913 <angles>; this allows `make depends' to work properly.
2915 * libguile.h: #include smob.h and pairs.h before the others; they
2916 define typedefs used by other headers.
2918 C files should #include only the header files they need, not
2919 libguile.h (which #includes all the header files); the pointless
2920 recompilation was wasting my time.
2921 * Makefile.in (all .o dependency lists): Regenerated.
2922 * libguile.h: Don't try to get a definition for size_t here...
2923 * __scm.h: Do it here.
2924 * _scm.h: Since this is the internal libguile header, put things
2925 here that all (or a majority) of the libguile files will want.
2926 Don't #include <libguile.h> here; that generates dependencies on
2927 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2928 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2929 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

2964 "weaks.h", "vports.h", "version.h", "vectors.h", "variable.h",
2965 "unif.h", "throw.h", "tag.h", "symbols.h", "struct.h",

3026 * weaks.c: Get "weaks.h".
3028 * stackchk.h: #include "libguile/debug.h",
3030 * print.h, read.h: #include "options.h", since everyone who uses
3031 either of these files will need that.
3033 * smob.h: #include "ports.h", "genio.h", and "print.h", since
3034 anyone who uses this file will need them to define the smob
3035 printing functions. Also, get markers.h, since people will need
3036 to #define the mark functions.
3038 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
3039 * ports.h: ... to here.
3041 * ports.h (scm_port_table_size): Explicitly give type as 'int';
3042 don't rely on archaic C default type rules.
3044 * fports.h: #include "libguile/ports.h", since you need that in
3045 order to parse this.
3047 * genio.h: #include "libguile/print.h", because you need that to
3048 parse this; don't bother #including "ports.h", since print.h gets
3051 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
3053 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
3054 this; it's now a reference to an element of *scm_root.
3056 * debug.h: Don't #include "options.h"; the compiler won't be able
3057 to find that once the headers are installed; instead, #include
3058 "libguile/options.h".
3059 * gc.h: Same, with marksweep.h.
3060 * mbstrings.h: Same, with symbols.h.
3061 * scmhob.h: Same, with _scm.h.
3062 * smob.h: Same, with params.h.
3064 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
3065 C files; there's no need for this, and it forces recompilations
3068 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
3070 * error.c (scm_error): declare scm_error_callback.
3072 * error.h: prototype for scm_error_callback.
3074 * __scm.h: define lgh_error.
3075 (SCM_SYSERROR): redefine using lgh_error.
3077 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
3079 * error.c (scm_error): new procedure.
3081 * error.h: prototype for scm_error.
3083 * Makefile.in (install): install scmconfig.h from the current
3084 directory, not $(srcdir).
3086 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3088 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3089 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3090 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
3091 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
3092 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
3093 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
3094 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
3095 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
3096 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3097 vports.h, weaks.h: #include "libguile/__scm.h", not
3098 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
3099 dependencies are within libguile properly.
3101 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3103 * Makefile.in (.c.x): Simplify; there's no need to run this rule
3104 when scmconfig.h doesn't exist.
3106 * load.c (scm_sys_try_load): Correct spelling.
3108 * feature.c (scm_loc_features): Make this static.
3110 * Makefile.in (libpath.h): Omit trailing slash from path. We
3111 shouldn't require it of users, so why put it here?
3113 Move code to initialize and search %load-path from ice-9 to C
3114 code, so we can use the load-path to find the ice-9 boot code;
3115 this makes it easier to run Guile without installing it. See
3116 corresponding changes in guile/Makefile.in.
3117 * feature.c: Move stuff concerned with the load path to load.c.
3118 (scm_compiled_library_path): Deleted.
3119 Don't #include libpath.h here.
3120 * feature.h: Don't mention scm_compiled_library_path.
3121 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
3122 <sys/stat.h>, and <unistd.h> (if present).
3123 (R_OK): #define if the system hasn't deigned to.
3124 (scm_loc_load_path): New variable.
3125 (scm_init_load_path, scm_sys_search_load_path,
3126 scm_sys_try_load_path): New functions.
3127 (scm_init_load): Initialize scm_loc_load_path to point to the
3128 value cell of the Scheme %load-path variable.
3129 * load.h: Add declarations for scm_sys_search_load_path,
3130 scm_sys_try_load_path.
3131 * init.c: Call scm_init_load_path.
3132 * Makefile.in (feature.o, load.o): Dependencies updated.
3134 * load.c, load.h: Rewrite using PROTO macro.
3136 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3138 * gc.c (scm_cellp): New function: C predicate to determine if an
3139 SCM value can be regarded as a pointer to a cell on the heap.
3141 * gc.h: Added declaration of scm_cellp.
3143 * gdb_interface.h: New file: The GDB interface header from the GDB
3146 * gdbint.c: New file: GDB interface.
3148 * gdbint.h: New file: GDB interface.
3150 * libguile.h: Added #include <libguile/gdbint.h>.
3152 * init.c (scm_boot_guile): Added scm_init_gdbint.
3154 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
3155 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
3156 found if object files and source are kept separate).
3158 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
3160 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
3162 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
3164 * configure.in: Don't substitute the values of TCL_SRC_DIR and
3165 TK_SRC_DIR; they're not relevant any more.
3167 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
3168 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
3170 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
3172 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
3173 search path, so we can find the <libguile/MUMBLE.h> headers.
3175 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
3177 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
3178 implicit in the .c.o rule.
3179 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
3182 Put the library path in a header file, instead of passing it on
3183 the command line in every compilation.
3184 * Makefile.in (libpath.h): New target.
3185 (feature.o): Depend on libpath.h.
3186 (clean): Delete libpath.h.
3187 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
3188 * feature.c: ... #include "libpath.h" here.
3189 * .cvsignore: Ignore libpath.h.
3191 Don't install the unwashed masses of Guile header files in the
3192 main #include path; put most of them in a subdirectory called
3193 'libguile'. This avoids naming conflicts between Guile header
3194 files and system header files (of which there were a few).
3195 * Makefile.in (pkgincludedir): Deleted.
3196 (innerincludedir): New variable; this and $(includedir) are enough.
3197 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
3198 (installed_h_files): Divide this up. Now this variable lists
3199 those header files which should go into $(includedir) (i.e. appear
3200 directly in the #include path), and ...
3201 (inner_h_files): ... this new variable says which files appear in
3202 a subdirectory, and are referred to as <libguile/mumble.h>.
3203 (h_files): List them both.
3204 (install): Create innerincludedir, not pkgincludedir. Put
3205 the installed_h_files and inner_h_files in their proper places.
3206 (uninstall): Corresponding changes.
3207 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3208 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3209 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
3210 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
3211 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
3212 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
3213 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
3214 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
3215 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3216 vports.h, weaks.h: Find __scm.h in its new location.
3217 * __scm.h: Find scmconfig.h and tags.h in their new locations
3218 (they're both "inner" files).
3220 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
3222 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
3224 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3226 * posix.c: Doc fixes.
3228 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
3230 * socket.c: Don't include a prototype for inet_aton; just use a
3231 K&R style declaration, to avoid warnings but minimize the chance
3232 of conflicts with the system.
3234 On NextStep, <utime.h> doesn't define struct utime, unless we
3235 #define _POSIX_SOURCE before #including it.
3236 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
3237 * acconfig.h: New comment text for above CPP symbol.
3238 * configure.in: Call it.
3239 * posix.c: #define _POSIX_SOURCE if it seems necessary.
3241 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
3243 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
3244 testing for __EMX__.
3246 * posix.c: #include <libc.h>, if it exists.
3248 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
3249 don't even know if the latter exists.
3251 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
3252 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
3253 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
3255 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
3257 (scm_init_posix): Use them when initializing the Scheme constants
3260 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3262 * Makefile.in (libdir, includedir, bindir): Use the
3263 autoconf-supplied values, instead of deriving them ourselves.
3264 (pkgincludedir, datadir, pkgdatadir): New variables.
3265 (install, uninstall): Put the header files in a special
3266 subdirectory, not in the main search path.
3268 * Makefile.in (ALL_CFLAGS): Provide the proper value for
3269 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
3271 * Makefile.in (IMPLPATH): Deleted; never used.
3273 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
3274 on the Tcl/Tk source any more.
3275 (INCLUDE_CFLAGS): Remove references to the above.
3277 * Makefile.in (version.o): Corrected dependencies.
3279 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
3281 * libguile.h: #include "version.h"
3283 * init.c (scm_boot_guile): Call scm_init_version.
3284 * gscm.c (gscm_run_scm): Call scm_init_version.
3286 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
3287 GUILE_VERSION): AC_DEFINE these.
3288 (acconfig.h): #undef the above symbols.
3290 * Makefile.in (libobjs): Add version.o.
3291 (installed_h_files): Add version.h.
3292 (c_files): Add version.c.
3293 (gen_c_files): Add version.x.
3294 (version.o): New rule.
3295 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
3296 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

3300 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,

3304 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
3305 weaks.o): Add version.h to dependency lists.
3306 (markers.o): Remove duplicate rule.
3308 * version.h: New file.
3310 * version.c: New file.
3312 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3314 * symbols.c (scm_strhash): scm_downcase is now a function, not an
3315 array; use it appropriately. Since GCC is quite happy to
3316 subscript functions, it never warned us about this; we should use
3317 -Wpointer-arith in the future. I guess we never tested
3320 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3322 * socket.c: Doc and copyright fixes.
3324 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3326 * debug.c: Fixed and improved gdb support.
3328 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3330 * socket.c: Added declaration of inet_aton to avoid compiler
3331 warning. (Hope this solution is correct.)
3333 * stime.c: Added declaration of ftime. (This is missing in
3336 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
3338 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3340 * Makefile.in (c_files): add strerror.c.
3342 * strerror.c: new file from Emacs' sysdep.c.
3343 maybe configure should also check for sys_errlist.
3345 * configure.in (AC_REPLACE_FUNCS): add strerror.
3347 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3349 * debug.c (scm_init_debug): Added initialization for
3350 scm_evaluator_traps.
3352 * debug.h, debug.c: Various name changes.
3353 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
3354 "debug-options-interface". See commentary in options.c.
3356 * options.h, options.c: Options now have documentation strings.
3357 Also added a long explanatory commentary.
3359 * eval.c, print.h, print.c, read.h, read.c: Modifications to
3362 * gscm.c, init.c, root.c, throw.c: Bug fixes:
3363 last_debug_info_frame is now updated in all cases.
3365 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
3368 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3370 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
3371 Added option STACK_CHECKING.
3373 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3375 * Makefile.in: Added {debug,options,srcprop}.{h,c}
3377 * __scm.h: Removed symbols for debugging support.
3379 * acconfig.h: Added symbols for debugging support.
3381 * configure.in: Added user option for debugging support.
3382 --enable-debug will include the debugging code into libguile.a.
3384 * continuations.c (scm_make_cont): Enlarged the #if 0 around
3385 scm_relocate_chunk_to_heap.
3387 * debug.c: New file: low-level debugging support. It also
3388 includes support for debugging with gdb. (The extensions to gdb
3389 are written by Per Bothner at Cygnus.)
3391 * debug.h: New file: low-level debugging support.
3393 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
3394 argument pairs. Extensive modifications to the debugging
3395 evaluator. Added "SECTION:" commentaries to clarify what happens
3396 when, during double compilation. Renamed EVALIMP --> EVALIM.
3397 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
3398 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
3399 the beginning of the file. New procedure: scm_unmemocopy.
3400 Added some global state variables needed by the debugging
3401 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
3402 check_entry, check_apply, check_exit, debug_options and
3403 evaluator_traps. New acro: undefine.
3405 * eval.h: Renamed EVAL --> XEVAL.
3407 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
3408 --> scm_make_weak_key_hash_table.
3410 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
3411 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
3413 * libguile.h: Conditionally include debug.h
3415 * objprop.c (scm_object_properties, scm_set_object_properties_x):
3416 scm_object_properties shouldn't return handle. `handle' now gets
3417 initialized in scm_set_object_properties_x. scm_object_properties
3418 doesn't any longer create an entry in scm_object_whash.
3420 * options.c: New file: handling of run time options.
3422 * options.h: New file: handling of run time options.
3424 * posix.c (scm_getpgrp): Cast pointer to getpgrp.

3445 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3447 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
3449 * libguile.h: #include "objprop.h"; I guess this was forgotten.
3451 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
3452 and should be called by the final client.
3454 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
3456 * gc.h: Use the PROTO macro when declaring functions.
3457 * gc.c: Use the PROTO macro when declaring static functions.
3458 Remove the CPP hair around function definitions.
3460 * gc.c (scm_init_storage): Initialize scm_asyncs.
3462 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
3463 preprocessor symbol; "__scm.h" is where it might get #defined.
3464 * __scm.h: Similar: #include <scmconfig.h> before testing
3467 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
3469 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
3471 * init.c (scm_boot_guile): Add init_func argument; call
3472 (*init_func) instead of calling scm_appinit; it's ucky to
3473 hard-code names for the user's procedures.
3474 * init.h (scm_boot_guile): Adjust declaration.
3476 * __scm.h (PROTO): New macro, for declaring functions with
3479 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
3480 eliminate all the __STDC__ conditionals.
3481 (scm_boot_guile): Add declaration.
3482 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
3483 Remove __STDC__ conditionals around function definitions; the
3484 declarations in init.h will provide the same information, more
3487 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
3488 complain about it in the error message; the error message is
3489 adequate without that note, and there's nothing the user can do
3492 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
3494 * Makefile.in (ancillary): Drop def.sed.
3496 * posix.c (scm_init_posix): Use numeric values, rather than
3497 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
3498 F_OK. The symbols aren't available on some systems, and I'm
3499 pretty sure their values are fixed by common widespread practice.
3500 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
3502 More functions unavailable on some systems.
3503 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
3504 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
3506 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3507 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
3508 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
3509 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
3510 stub that signals an error as the #else.
3512 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
3514 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
3516 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
3518 * unif.c: include ramap.h.
3520 * read.c (endif): case_insensative_p renamed case_insensitive_p.
3522 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
3524 * ports.c: include sys/ioctl.h.
3526 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
3528 * configure.in: check for sys/ioctl.h.
3530 * ports.c: include <malloc.h> not "malloc.h".
3532 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3534 * fports.c: remove ttyname and tmpnam declarations.
3536 * posix.c: fewer ttyname declarations.
3538 * fports.c: include <string.h> not "string.h".
3540 * init.c, ioext.c: include string.h and unistd.h.
3542 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3544 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
3545 genio.c, simpos.c, vports.c: include string.h.
3547 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
3549 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
3551 (scm_addr_buffer_size): change type from scm_sizet to int.
3552 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
3553 from scm_sizet to int.
3555 * error.c: include unistd.h.
3557 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
3560 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
3562 * __scm.hd, def.sed: deleted.
3564 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
3566 Changes for NeXT, suggested by Robert Brown.
3567 * configure.in: Call AC_TYPE_MODE_T.
3568 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
3569 NeXT. Put header file list in alphabetical order.
3570 * configure, scmconfig.h.in: Regenerated.
3571 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
3573 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
3576 * acconfig.h: New file, providing documentation for the CPP
3577 symbols defined in configure.in
3578 * acconfig-1.5.h: Removed; superceded by the above.
3580 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
3582 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
3584 * fports.c (scm_open_file): don't return #f, throw error.
3586 * ioext.c (fileno): renamed from %fileno.
3587 (soft-fileno): deleted.
3589 * ports.c (scm_port_revealed): don't need to check for -1 from
3591 (scm_set_port_revealed_x): return unspecified, not #f.
3593 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
3595 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
3597 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
3599 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
3601 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3603 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
3604 This is necessary on Ultrix, and doesn't hurt portability.
3606 * Makefile.in (dist-dir): New target, implementing a new dist system.
3607 (installed_h_files): Put in alphabetical order.
3608 Remove duplicate entries for markers.h and unif.h.
3609 (c_files): Remove duplicate entries for markers.c.
3610 (ancillary): Renamed from anillery; all uses changed. Remove
3611 PLUGIN; it's a directory, and needs special treatment in dist-dir.
3612 Remove all the ../doc/* files; doc/Makefile.in handles that.
3614 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3616 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3617 every if must have an else, or else the whole command has a
3618 non-zero exit code whenever the if's condition is false.
3620 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
3622 * posix.c: include string.h.
3624 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3626 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
3629 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
3630 Remove leading % from scheme names.
3631 Do not return error values, call SCM_SYSERROR or similar.
3633 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
3635 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
3637 * struct.c (scm_init_struct): new file.
3639 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
3641 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
3642 (scm_list_head): added list-head for rapidly chopping argument
3643 lists off of longer lists (and similar).
3645 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
3647 * objprop.c (scm_object_property): assq the cdr of the whash
3648 handle for obj, not the handle itself.
3650 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
3652 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
3653 weak hash tables last of all marking to avoid an obscure gc bug.
3654 WARNING: circular lists stored in a weak hash table will hose us.
3656 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
3658 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
3659 new functions similar to scm_substring_move_left_x and
3660 scm_substring_move_right_x.
3662 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
3664 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
3667 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
3669 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
3671 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
3673 * strports.c (scm_strprint_obj): convenience function. C for
3674 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
3676 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
3677 removed to a separate library
3679 * init.c (scm_boot_guile): copied from guile-tcl.c.
3680 Initialization specific to tcl interpreters removed.
3682 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
3684 * ports.c (scm_ports_prehistory): size malloced here doesn't
3685 matter so long as it is non-0 (got rid of "* 4").
3687 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3689 * gscm.h: gscm_mkarray eliminated (presumably was not being used
3690 since its definition was bogus).
3692 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
3694 * mallocs.[ch]: back again (for rx at least).
3696 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
3698 * ports.c: removed functions relating to the mapping between ports
3699 and descriptors. (That stuff is unix-specific and should be collected
3700 in a separate library).
3702 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
3703 (Tom Mckay@avanticorp.com)
3705 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
3707 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3708 handled correctly (SCM_FREEP was applied to them) -- test for
3709 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
3710 being overwritten with #f. (brown@grettir.bibliotech.com)

3734 * gscm.c (gscm_run_scm): got rid of objprop.
3736 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>

3741 * procprop.c (scm_stand_in_scm_proc):
3742 NOTE: don't use a alist here.
3743 (scm_set_procedure_properties_x): fix type checking throughout this file.
3745 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
3747 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
3748 after freeing part of the port table.

3753 * vports.c (scm_make_soft_port): allocate a port table entry
3754 (possibly triggering gc) before setting the tag of the corresponding
3757 * pairs.c (scm_delq_x): never throw an error.
3759 * vectors.c (scm_make_vector): made the default vector fill argument
3760 into '() (much more useful than the previous value, "#unspecified")
3762 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
3764 * ports.c (scm_add_to_port_table): Added fields
3765 to port table entries: file_name, line_num, col.
3766 Update these in open_file, gen_getc and gen_ungetc.
3767 Added procedures to access those fields.
3769 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
3771 * procs.c (scm_make_subr_opt): new entry point for making
3774 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
3776 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
3778 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
3780 * numbers.c (scm_exact_p): This function no longer
3781 implements "integer?".
3783 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
3785 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
3786 (scm_gc_stats): return an assoc of useful data. Replaces "room"
3787 and the stats reporting formerlly built into repl.
3789 * repl.[ch]: removed.
3790 GC statistics keeping moved to gc.c.
3791 Other statistics keeping can be done from Scheme.
3792 REPLS are now written in Scheme.
3794 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
3796 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky
3797 conservatively marked objects).
3799 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
3801 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
3803 * feature.c (scm_compiled_library_path): moved here from repl.c.
3804 This file is for stuff relating specifically to Scheme libraries
3807 * eval.c (scm_m_define): don't give warning about redefinition, don't
3810 NOTE: this should throw a resumable exception with parameters --
3811 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
3813 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.

3835 because it changes size.
3837 (stputc stwrite): check/change the strings length with interrupts
3840 * objprop.c (scm_set_object_property_x &c): use the generic
3841 hashing functions and be threadsafe.

3844 (per suggestion jaffer@gnu.ai.mit.edu).
3846 * mbstrings.c (scm_multi_byte_string): guard against argument list
3849 * strings.c (scm_make_string): loop cleanup

3877 initialization to fix a race condition.
3879 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

3902 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
3903 set the multi_byte flag correctly in symbols. This is wrong.
3904 intern_obbary_soft and msymbolize should take an extra parameter.
3905 Also, weird multibyte symbols don't print correctly.
3906 The weird symbol syntax is also a bit bogus (emacs doesn't quite
