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

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

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

275 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
276 (scm_display_error_message): use RO macros when strings may be RO.
277 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
278 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
279 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

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

478 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
481 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
483 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
485 Merge GH interface library into libguile.
486 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
487 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
488 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
489 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
491 (EXTRA_libguile_la_SOURCES): ... here.
492 (pkginclude_HEADERS): Add variable, to get gh.h installed.
493 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
494 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
495 New variables, describing how to build the gh test programs.
496 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
497 build the test programs, and we probably should have been linking
498 libguile.la against them all along, to support AIX shared libs.
499 Add cflags for threads to CFLAGS; add libs for threads to new
500 variable THREAD_LIBS, used in Makefile.am.
501 * ChangeLog-gh: log from old `gh' subdirectory.
502 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
504 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
506 * acconfig.h: Undo change of Apr 9; including the definition of
507 PACKAGE in the guile headers conflicts with applications' own
509 * scmconfig.h.in: Regenerated.

515 * filesys.h: Added prototype.
517 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
518 when PROC is receiving no arguments.
520 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
522 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
523 have S_IFSOCK. This is the case under Ultrix.
525 * posix.c (scm_status_exit_val, scm_status_exit_val,
526 scm_status_term_sig, scm_status_stop_sig): Modified to work with
527 Ultrix versions of WIFSTOPPED, etc., which assume that their
528 arguments are lvalues (hmm).
530 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
534 * throw.c: Doc fixes; rearranged.
536 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
538 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
540 * acconfig.h: Added entry for PACKAGE.
541 * scmconfig.h.in: Regenerated.
543 Changes to work with automake-1.1n, which has better libtool support.
544 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
545 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
547 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
549 * Makefile.in: Rebuild.

553 * stime.c (scm_mktime): take an optional zone argument.
554 (scm_localtime): check putenv return value.
555 (scm_strftime, scm_strptime): moved from posix.c. move #include
557 stime.h, posix.h: update prototypes.
558 (bdtime2c, setzone, restorezone): new static procedures.
559 (scm_mktime, scm_strftime): use them.
560 (scm_strftime): don't call mktime before strftime. Use
561 filltime for return value.
562 (filltime): convert NULL zname to #f.
563 (scm_strptime): return a count of characters consumed, not
564 the remaining string.
566 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
568 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.

575 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
577 * stime.c (scm_init_stime): don't define ticks/sec.
578 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
579 return value problem and is still portable.)
581 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
583 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
584 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
585 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
586 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
587 cpp_err_symbols.c): Corresponding changes.
588 * Makefile.in: Regenerated.
590 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
592 * posix.c (scm_putenv): don't check HAVE_PUTENV.
593 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
594 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
595 * putenv.c: new file, from sh-utils 1.12.
597 * posix.c (scm_environ): use malloc in place of scm_must_malloc
598 since allocation isn't for Scheme objects.
599 (scm_putenv): copy strings before placing in the environment.
601 * stime.c (scm_current_time): throw an error if time returns -1,
602 instead of returning #f.
603 (scm_get_internal_real_time, scm_get_internal_real_time): use
604 scm_long2num for return value instead of SCM_MAKINUM.
606 * stime.h: prototypes updated.
608 * stime.c (scm_time_in_msec): apparently unused, deleted.
610 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
612 * configure.in: check for gettimeofday.
614 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
615 which may be more usefully portable than a gettimeofday interface.
617 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
619 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
621 * Makefile.in: Regenerated.
623 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
625 * stime.c (filltime): recovered static procedure.
626 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
629 * posix.h: add prototype for scm_close_pipe, remove prototypes for
630 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
632 * posix.c (scm_mknod): split the mode argument into type and perms
633 arguments, like the extra fields returned by stat.
635 * fports.c (scm_pipob): set the close, free and print procedures.
636 (scm_close_pipe): new procedure.
638 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
639 define them in boot-9.scm
641 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
643 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
644 wan't defined. Don't include fd.h.
646 * Previously fd.h was regenerated whenever configure was run,
647 forcing a couple of files to be recompiled.
649 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
650 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
651 Check for _fileno as well as _file.
653 * ioext.c: don't fd.h.
654 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
657 * Change the stratigy for getting information about errno
658 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
659 generating lists of symbols during the build process, which will
660 not always work, include comprehensive lists in the distribution.
661 To help keep the lists up to date, the "check_signals" and
662 "check_errnos" make targets can be used.
664 * configure.in: don't check for a command to extract errno codes.
665 * Makefile.am: update file lists, remove errnos.list and errnos.c
666 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
667 check_errnos targets.
668 (CLEANFILES): remove errnos.c and errnos.list, add
669 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
670 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
671 * errnos.default: deleted.
672 * cpp_signal.c: new file.
673 * cpp_errno.c: renamed from errnos_get.c.
674 * cpp_err_symbols, cpp_sig_symbols: new files.
675 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
676 * error.c (scm_init_error): #include cpp_err_symbols instead of
678 * posix.c (scm_init_posix): don't intern signal symbols. #include
681 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
683 * strop.c (scm_i_index): allow the lower bound to be equal to the
684 length of the string, so a null string doesn't always give an error.
686 * posix.h: new prototypes.
687 * posix.c (scm_status_exit_val, scm_status_term_sig,
688 scm_status_stop_sig): new functions, as in scsh. They break down
689 process status values as returned by waitpid.
691 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
693 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
694 configure doesn't know about it.
696 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
698 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
700 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
701 which defines C variables with global linkage.
703 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
705 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
708 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
710 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
711 has time to check why this doesn't work well with continuations.
713 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
715 * Fix shell syntax error; some shells won't tolerate
716 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
718 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
720 * posix.c (scm_uname): throw an error if uname fails instead
723 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
725 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
728 * async.c (scm_ints_disabled): definition moved from error.c.
730 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
732 * acconfig.h: Removed PACKAGE.
734 * scmconfig.h.in: Regenerated.
736 * snarf.h: g++ says it's non-portable not to specify the first
737 argument in a varargs declaration. I introduced the first
738 argument by using preprocessor conditionals.
740 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
742 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
743 (scm_freopen): use RO string macros for filename and modes.
744 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
746 * posix.c (scm_getgrgid): simplify conversion of name to C string.
747 (scm_mknod): use RO string macros for path.
749 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
750 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
752 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
753 use SCM_ROSTRINGP and SCM_ROCHARS.

757 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
760 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,

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

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

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

893 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
895 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
897 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
898 from pairs with a GLOC in the car.
900 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
901 otherwise `symbol-hash' will behave badly.
902 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
903 we get segmentation fault!
905 * symbols.c: Added #include "weaks.h". New functions:
906 `builtin-bindings' and `builtin-weak-bindings'. (These will be
907 moved to an extraneous library when we split libguile.)
909 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
911 * filesys.c (scm_stat): stat now takes fport arguments too as
912 documented in the manual.
914 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
916 * debug.c (scm_single_step): Bugfix: Call continuation with
917 scm_call_continuation instead of throwing to it.
919 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
921 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
922 argument wasn't declared to be optional.
924 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
926 * stime.c (scm_init_stime): Add feature "current-time".
928 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
930 * throw.h: prototype for scm_exit_status.
931 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
932 args to derive an exit status. Allows (quit) to work from a
934 (scm_exit_status): new function.
937 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
939 * eval.c (scm_deval): Removed some old code.
940 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
942 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
945 * symbols.c (msymbolize): Bugfix: Must initialize property list to
948 * procs.c: Introduce the existent C function scm_thunk_p at the
949 Scheme level as well.
951 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
953 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
954 used from C to easily lookup the value of a symbol in the current
957 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
959 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
960 scm_init_unif in this file. This will also fix a previous problem
963 * configure.in: Added AM_MAINTAINER_MODE
965 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
967 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
970 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
972 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
973 source files that are not always included in libguile but should
974 have their dependencies calculated by automake. This variable is
975 recognized by automake, no further magic is needed.
976 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
977 to deal exclusively with *.lo files, as it seems. The *.o files
978 are built automatically when the corresponding *.lo file gets
981 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
983 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
986 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>

990 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
992 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
993 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
994 They should only be included in the library at configure.in's
996 (libguile_la_LDADD): Include the appropriate .lo files here.
997 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
998 so we know when to build them (and their .lo bretheren).
999 * configure.in (LIBLOBJS): New substituted variable. We let
1000 configure decide which .o files to include in LIBOBJS, and then
1001 put the corresponding list of .lo files in LIBLOBJS. The latter
1002 is what we pass to libtool.
1003 * Makefile.in, configure: regenerated.
1005 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
1007 * symbols.c (scm_sysintern0): New function. Contains the core of
1008 old scm_sysintern but doesn't take a second value argument.
1009 (scm_sysintern): Now uses scm_sysintern0.
1010 (scm_sysintern_no_module_lookup): Renamed to
1011 scm_sysintern0_no_module_lookup and doesn't take a second value
1012 argument any longer.
1014 * symbols.h (scm_sysintern0: Added declaration.
1016 * options.c (scm_init_opts): Use scm_sysintern0 instead of
1017 scm_sysintern when interning option keys. Otherwise we risk
1018 destroying the values of already interned variables.
1020 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
1021 scheme-level boolean (use SCM_NFALSEP).
1023 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
1025 (scm_backtrace): New function. (C version of old function from
1026 boot-9.scm) Motivation: Make it possible to display backtraces
1027 without depending on boot-9.scm. (I'm uncertain if this
1028 motivation is good enough...)
1030 * root.h (scm_root_state): Add member the_last_stack_var.
1031 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
1033 * root.c (mark_root): Mark scm_the_last_stack_var.
1035 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
1038 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
1040 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
1041 1. mark_lazy_catch didn't mark the smob.
1042 2. Both functions above have standard variants:
1043 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
1044 free_lazy_catch --> scm_free0.
1046 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
1048 * throw.c (scm_internal_lazy_catch): New function.
1049 (scm_lazy_catch): Rewritten to use it.
1050 (scm_ithrow): Handle the new lazy catch representation.
1051 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
1052 that doesn't have a jmpbuf is a lazy catch clause.
1053 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
1054 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
1055 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
1057 (scm_init_throw): Register the new lazy-catch smob type.
1058 * throw.h (scm_internal_lazy_catch): decl for new function.
1060 * throw.c (scm_internal_catch): Doc fixes.
1062 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
1063 configure.in. Including this might cause problems if applications
1064 that link against libguile include their own copies of alloca, but
1065 if they're using autoconf, they should be adding libguile to LIBS
1066 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
1067 the copy in libguile, and things will be okay. (I think.)
1069 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1071 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
1073 strop.h: move prototypes too.
1075 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
1077 * posix.c (scm_init_posix): don't intern EINTR since it's now done
1080 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
1081 etc. I deleted them from filesys.c long ago, but didn't
1082 notice they were here too (although ineffective since
1083 sys/stat.h wasn't included).
1085 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
1087 * eval.c: Don't define alloca in GCC case. gcc will automatically
1088 use __builtin_alloca if appropriate.
1090 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1092 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
1093 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
1094 that values of automatic variables are preserved. See comments
1095 for safe_setjmp for details.
1097 Change from Thomas Morgan:
1098 * variable.c: Include eq.h.
1099 (var_equal): New function.
1100 (variable_smob): Use var_equal as the discriminator for variables.
1102 * throw.c (s_throw): Remove extraneous declaration.
1104 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
1105 * eval.c: Add necessary CPP cruft to support that.
1106 * configure, Makefile.in, scmconfig.h.in: regenerated.
1108 Change from Thomas Morgan:
1109 * procprop.c (scm_procedure_properties): Convert the Scheme
1110 boolean returned by scm_procedure_p into a C boolean before using
1111 it as a condition for SCM_ASSERT.
1112 (scm_procedure_property): Likewise.
1114 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
1115 indications of Unixness.
1118 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
1120 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
1122 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
1124 * read.c (scm_lreadr): use scm_misc_error to improve one of the
1125 "unknown # object" error messages.
1127 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
1128 (scm_i_index) and declare it static. Add a 'direction' argument
1129 to indicate what way the search should go.
1130 (scm_i_index): throw out-of-range error instead of wrong-type-arg
1132 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
1133 strop.h: remove scm_i_index, scm_i_rindex prototypes.
1135 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1137 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
1139 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
1140 to avoid clash with various scsh forks.
1142 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
1144 The following two changes (ramap.c, throw.c) are motivated by the
1145 apparent unportability of forward declarations of static arrays of
1146 the form `static foo bar[];'.
1148 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
1149 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
1151 * throw.c (scm_throw): Moved above scm_ithrow.
1153 * options.h: Removed the extern declarations of scm_yes_sym and
1154 scm_no_sym since these are static.
1156 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1158 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
1160 * Makefile.am: remove AWK=@AWK@.
1161 Add a rule for generating errnos.list.
1162 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
1164 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
1165 don't extract errnos, just set a variable (avoids the
1166 need to recompile error.c just because configure is run.)
1168 * unif.h: update prototypes.
1169 * unif.c (scm_uniform_array_read,write): change the offset and
1170 length arguments to start and end, for consistency.
1172 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
1174 * ioext.h: update prototypes.
1175 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
1176 scm_read_line_x, it's a more general procedure using an
1177 interface from scsh. read-line and read-line! are now defined
1179 Note that the new read-line trims the terminator
1180 by default, previously it was appended to the returned string. An
1181 optional argument specifies how to process the terminator (scsh
1182 compatible). For the old behaviour: (read-line port 'concat).
1183 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
1184 returns a pair, but is converted to multiple values if the scsh
1187 socket.h: update prototypes.
1188 * socket.c (scm_recvfrom): for consistency with other procedures,
1189 take start and end as separate optional arguments.
1190 (scm_recv, scm_recvfrom): don't allow the second argument
1191 to be a size, only a buffer. Change the scheme names to
1192 recv! and recvfrom!. Don't return the buffer.
1194 * ioext.h, posix.h: move prototypes too.
1195 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
1196 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
1197 "read.h" and "unif.h".
1198 * ioext.c: include "chars.h"
1200 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
1202 * dynl.c: The dynamic linking and module registration functions
1203 are now defined even when dynamic linking is not available for the
1204 host system. Some of their functionality can be done without
1205 dynamic linking; when it's really needed, they throw errors.
1207 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
1209 * configure.in: Only define DYNAMIC_LINKING when one of the system
1210 dependent functions is detected.
1211 * dynl.c (scm_dynamic_func): New function to get the address of a
1212 function in a dynamic object.
1213 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
1214 produced by scm_dynamic_func as the thing to call.
1216 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
1218 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
1219 (scm_register_module_xxx, scm_registered_modules,
1220 scm_clear_registered_modules): New functions.
1222 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
1224 * symbols.c (scm_sysintern): Renamed to
1225 scm_sysintern_no_module_lookup.
1226 (scm_sysintern): New function to take the place of the old
1227 scm_sysintern. It uses the current toplevel lookup closure to give
1228 the symbol its value. This is a temporary hack to put packages
1229 like gtcltk into their own module.
1230 (scm_can_use_top_level_lookup_closure_var): New variable to tell
1231 us whether `scm_top_level_lookup_closure_var' has been initialized
1233 * eval.c (scm_init_eval): Set it.
1235 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
1237 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
1238 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
1240 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
1242 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
1243 scm_sys_dup): deleted: FD capability will be added to other
1245 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
1246 scm_fd_free, fd_smob, scm_intern_fd.
1247 (scm_open): renamed from scm_sys_open. Return a port instead of
1248 an FD object. Make the mode argument optional.
1249 (scm_sys_create): deleted, it's just a special case of open.
1250 (scm_init_filesys): move interning of constants O_CREAT etc.,
1251 here (were previously using SCM_CONST_LONG macro).
1252 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
1254 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
1255 include "fports.h" and <stdio.h>
1256 (scm_stat, scm_select): don't support FD objects.
1258 * error.h: adjust scm_syserror_msg prototype.
1259 * error.c (scm_syserror_msg): take an extra argument for errno.
1260 Using the global value didn't always work, since it could be
1261 reset by procedure calls in the message or args arguments.
1263 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
1264 I don't understand why the check was there (and what about the
1267 * strop.c (scm_string_copy): allow shared substrings to be copied.
1269 * unif.h: corresponding change to prototypes.
1270 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
1271 recognize two new optional arguments: offset and length. Allow
1272 the port argument to be an integer (file descriptor, for scsh).
1273 Include <unistd.h> for "read" prototype.
1275 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
1277 * socket.c: don't include filesys.h.
1279 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
1281 * Makefile.am: add AWK=@AWK@ (?)
1283 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
1285 Add a rule to generate errnos.c from errnos.
1286 * error.c (scm_init_error): include errnos.c.
1287 * errnos_cnvt.awk: new file, converts the list of errno codes to
1289 * errnos_get.c: new file.
1290 * errnos.default: new file, contains errnos to try if they can't
1291 be extracted from errno.h.
1292 * configure.in: if using GCC, try and extract errno codes from
1296 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
1298 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
1299 * Makefile.am: Made libguile into a libtool library.
1300 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
1301 Set libtool_libs to indicate that libguile is a libtool library.
1302 See guile/ChangeLog for details.
1303 * .cvsignore: ignore "*.lo", the libtool library objects.
1305 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1307 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
1308 use htons in getservbyport argument.
1310 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
1312 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
1313 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
1316 * objprop.c (scm_object_property): No need to take the CDR of the
1317 value returned by scm_object_properties, since Aug 20 change.
1319 * configure.in: When checking for struct linger, #include
1320 <sys/types.h> as well as <sys/socket.h>. I've never known
1321 <sys/types.h> to cause any portability problems, and Solaris's
1322 <sys/socket.h> needs it.
1323 * configure: Rebuilt.
1325 I think the Sun compiler has chosen a perverse way to interpret
1326 ANSI declarations combined with K&R definitions. We'll
1327 appease it a little bit. But when it invades France, we fight.
1328 * print.c (scm_iprlist): Change 'tlr' argument to an int.
1329 * print.h (scm_iprlist): Here too.
1330 * numbers.c (scm_divbigdig): Change definition to match
1331 declaration in numbers.h.
1332 * unif.c (scm_makflo): Change definition to match declaration in
1335 * init.c (scm_boot_guile): Don't return the value of
1336 scm_boot_guile_1. This function doesn't return a value;
1337 scm_boot_guile_1 doesn't return a value (or return at all).
1339 * eval.c (unmemocopy): Add a semicolon to appease the Sun
1342 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
1343 compile. I have a feeling this function is a bad idea anyway ---
1344 one should always test for features, not systems.
1346 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
1347 semicolons. Only pure luck kept this from being noticed earlier.
1349 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
1351 * socket.c (scm_recvfrom): Added missing semicolon.
1353 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1355 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
1356 the buffer and start and end positions for scsh networking
1359 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
1361 * configure.in: Revert previous change to this file; the problem
1362 is due to transient automake weirdness.
1363 * configure: Rebuilt.
1365 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
1366 PLUGIN/guile.libs. configure generates the latter from the former.
1367 * Makefile.in: Rebuilt.
1369 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
1370 need this if we install scripts, like guile-snarf.
1371 * configure: Rebuilt.
1373 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1375 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
1377 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
1379 * socket.c (scm_addr_vector): fix faulty scm_listify.
1381 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
1383 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
1384 style block comment is no longer considered an error.
1386 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
1388 * PLUGIN/guile.libs.in: New file.
1389 * PLUGIN/guile.libs: Removed from repository.
1390 * configure.in: Create PLUGIN/guile.libs from
1391 PLUGIN/guile.libs.in. This is for including additonal libraries
1392 needed for dynamic linking.
1393 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
1394 instead of PLUGIN/guile.libs.
1396 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
1398 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
1400 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
1401 occurrences of the given element from the list, not just the
1402 first. This is how the Emacs Lisp functions behave, how the
1403 analogous Common Lisp functions behave, and (I believe) how the
1404 older Maclisp functions worked. I realize that this change may
1405 break code, but it seemed better to break it before the Guile
1408 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
1409 Their prototypes were already present in gc.h, but they weren't
1411 (scm_init_storage): Initialize scm_protects.
1412 * root.c (scm_protects): New element of scm_sys_protects.
1414 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
1416 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1418 * libguile.h: Added #include "libguile/net_db.h".
1420 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
1421 30 change. That file is only meant for communication between the
1422 configuration process and load.c. If code linked against libguile
1423 wants to get at the paths mentioned in libpath.h, it can call
1424 functions declared in load.h.
1426 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1428 * libguile.h: Removed #include "libguile/fdsocket.h"
1430 * net_db.c: Added #include <sys/socket.h>.
1432 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
1434 * filesys.c (scm_input_waiting_p): use select in preference to
1435 FIONREAD, since the latter doesn't detect EOF.
1436 Throw error if neither select nor FIONREAD available.
1438 * socket.c (scm_connect): take a port, not a fd object.
1439 (scm_fill_sockaddr): throw an error if fam is not recognised.
1440 (scm_bind): use scm_fill_sockaddr.
1441 (scm_listen): take a port, not a fd object.
1442 (scm_accept): take and return a port. return #f in the car if
1443 address can't be got
1444 (scm_sock_fd_to_port): new procedure.
1445 (scm_socket): use scm_sock_fd_to_port.
1446 (scm_addr_vector): throw error if unrecognised address type.
1447 take an extra argument with the calling procedure name.
1448 (scm_getsockname): take a port. return #f if address can't be got.
1449 (scm_getpeername): take a port. return #f if address can't be got.
1450 (scm_recvfrom): take a port. return #f for address component if can't
1452 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
1453 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
1455 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
1457 * throw.c (scm_internal_catch): Make body funcs and handler funcs
1458 use separate data pointers, to allow them to be designed
1459 independently and reused.
1460 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
1461 Renamed from catch_body, catch_handler, and uncaught_throw; made
1463 (struct scm_catch_body_data): Renamed from catch_body_data; moved
1465 (scm_catch): Use the above.
1466 (scm_throw): Don't bother printing a message for an uncaught
1467 throw; we establish a default handler in init.
1468 * throw.h (scm_internal_catch): Prototype updated.
1469 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
1471 (struct scm_body_thunk_data): New structure, used as data
1472 argument to scm_body_thunk.
1473 * init.c (struct main_func_closure): New structure, packaging up
1474 the data to pass to the user's main function.
1475 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
1476 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
1477 scm_internal_catch to establish a catch-all handler, using
1478 scm_handle_by_message. This replaces the special-case code in
1480 (invoke_main_func): Body function for scm_internal_catch; invoke
1481 the user's main function, using the main_func_closure pointer to
1482 decide what to pass it.
1483 * root.c (struct cwdr_body_data): Remove handler_proc member.
1484 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
1485 (cwdr_handler): Removed.
1487 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1489 * socket.h (SCM_P): update bind prototype.
1490 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
1491 include "feature.h".
1492 (scm_socket): return a port, not a file descriptor object.
1493 include "fports.h" and <unistd.h>
1494 (scm_bind): take a port, not a file descriptor object.
1495 take an extra argument for address args.
1497 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
1498 INADDR_NONE, INADDR_LOOPBACK.
1500 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1502 * init.c: include net_db.h and not fdsocket.h.
1503 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
1505 * Makefile.am: corresponding changes.
1506 * socket.h: renamed from fdsocket.h, fix names.
1507 * net_db.h: renamed from socket.h, fix names.
1508 * socket.c: renamed from fdsocket.c.
1509 remove _sys from procedure names.
1510 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
1511 add "socket" to features list.
1512 * net_db.c: renamed from socket.c.
1513 remove _sys from procedure names.
1514 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
1515 add "net-db" to features list.
1516 include "net_db.h". don't include <sys/socket.h> or
1519 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1521 * tags.h (scm_tags): Removed comma at end of last enumerator.
1523 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
1525 Don't use GCC extensions to allocate space for debugging frames.
1526 (Here he goes again! Why do we put up with this?!)
1527 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
1528 an scm_debug_info structure, not an in-line array of them. Add
1529 'info' member, to say how many vect elements we've used, for eval
1531 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
1532 a new variable debug_info_end to mark the end of vect, instead of
1533 the address of the 'info' pointer itself.
1534 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
1535 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
1536 (SCM_APPLY): Explicitly allocate space for debug.vect.
1537 * debug.c (scm_m_start_stack): Same, for vframe.vect.
1538 * stacks.c: Adjusted for new debug frame structure.
1539 (RELOC_INFO, RELOC_FRAME): New macros.
1540 (stack_depth, read_frames): Use them, and new scm_debug_frame
1541 element 'info', instead of magically knowing that eval frames have
1542 an info pointer sitting after vect.
1543 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
1545 (scm_init_stacks): Formatting tweaks.
1547 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
1549 Give GCC more control flow information, so it can be sure that
1550 variables aren't used uninitialized.
1551 * error.h (scm_error, scm_syserror, scm_syserror_msg,
1552 scm_sysmissing, scm_num_overflow, scm_out_of_range,
1553 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
1554 scm_misc_error): Tell GCC that these functions never return.
1555 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
1556 out the field type, call abort if SCM_ASSERT returns, to placate
1558 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
1559 scm_wta ever returns. We can't handle this case anyway, and this
1560 gives the optimizer more information.
1561 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
1562 scm_wta ever returns.
1564 In some cases, the code is fine, but GCC isn't smart enough to
1565 figure that out; this usually happens when one variable is only
1566 initialized and used when a particular condition holds true, and
1567 we know that condition will never change within a given invocation
1568 of the function. In this case, we simply initialize the variables
1569 to placate the compiler, hopefully to a value which will cause a
1570 crash if it is ever actually used.
1571 * print.c (scm_iprin1): Initialize mw_pos.
1572 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
1573 * throw.c (scm_ithrow): Initialize dynpair.
1574 * unif.c (scm_uniform_vector_ref): Initialize cra.
1575 * struct.c (init_struct): Initialize prot.
1576 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
1578 * strports.c (scm_eval_0str): Don't return uninitialized garbage
1579 if EXPR contains no expressions.
1581 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
1583 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
1584 cause an infinite loop (???). So much for the algebraic
1585 equivalency of variable-sized arrays and alloca...
1587 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
1589 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
1590 a SCM boolean, not a C boolean.
1592 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
1594 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
1595 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
1596 rules for raising scm_mtrigger. Previously, unfortunate but not
1597 unlikely circumstances could result in almost constant invokation
1598 of the gc. Now, this situations should be less likely, but they
1599 are not prevented completely.
1601 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
1603 * numbers.c (scm_fuck): Procedure removed; looks like old test
1605 * numbers.h: Prototype removed.
1607 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
1609 * debug.h (scm_debug_frame): Change `vect' member from an in-line
1610 array to a pointer, to match my Nov 21 change in eval.c.
1612 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1614 * libguile.h: Added #include "libguile/backtrace.h", #include
1615 "libguile/stacks.h".
1617 * strings.c (scm_string scm_make_string scm_string_ref
1618 scm_string_set_x scm_string_equal_p scm_string_append):
1619 Bugfix according to scm patch from Aubrey Jaffer:
1620 Corrected long-standing
1621 (not (eqv? (integer->char 128)
1622 (string-ref (make-string 1 (integer->char 128)) 0)))
1623 bug found by John Kozak <jk@noontide.demon.co.uk>.
1625 * strports.c, strports.h: Make scm_eval_0str return the value of
1626 the last expression evaluated (previously, it returned void).
1628 * strports.c, strports.h: New function: scm_read_0str. Does what
1631 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1633 * simpos.c (scm_getenv): return #f if string can't be found in the
1634 environment instead of throwing an exception, for compatibility
1635 with numerous other systems.
1637 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
1639 * Makefile.am (.c.x): Use guile-snarf.
1640 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1642 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1644 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1646 * backtrace.c (scm_display_error_message): Made non-static, and
1647 renamed from display_error_message.
1648 * backtrace.h (scm_display_error_message): Added extern decl.
1649 * throw.c (uncaught_throw): Use it to display the error message.
1651 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1653 * inet_aton.c: Use #if 0, not #ifdef 0.
1655 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1657 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1658 to convert the returned value.
1659 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1660 the offset argument.
1662 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1664 Add new interface to catch/throw, usable from C as well as
1666 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1667 (scm_internal_catch): New function, replaces...
1668 (scm_catch_apply): Deleted.
1669 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1670 mechanism which is a bit more code, but can be used nicely from C
1671 and implement the Scheme semantics as well.
1672 (scm_internal_catch): This is the replacement; it's named after
1673 the analogous function in Emacs.
1674 (scm_catch): Reimplemented in terms of the above.
1675 (struct catch_body_data, catch_body, catch_handler): New
1676 functions, used by scm_catch.
1677 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1678 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1679 support for new cwdr.
1681 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1684 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1686 * acconfig.h: Added DYNAMIC_LINKING symbol.
1687 * configure.in: Add option and checks for dynamic linking.
1688 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1689 dynl.h: New files for dynamic linking support.
1690 * Makefile.am (libguile_a_SOURCES):
1692 (modinclude_HEADERS): Added "dynl.h".
1693 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
1695 * init.c (scm_boot_guile_1): Call
1696 scm_init_dynamic_linking to initialize dynamic linking support.
1698 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
1700 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
1701 (as we Schemers say). It needs to be global, so that I can tweak
1702 it for the proper operation of unexec.
1703 (scm_boot_guile_1_live): New variable, see above.
1705 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
1707 * guile-snarf.sh: Removed.
1708 * PLUGIN/guile.libs: Added dependency for -lm.
1709 * acinclude.m4: Renamed from aclocal.m4.
1710 * PLUGIN/greet: Removed.
1711 * Makefile.am, aclocal.m4: New files.
1712 * configure.in: Updated for Automake.
1714 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
1716 * eval.c (scm_definedp): Use top_level_lookup_closure_var
1717 and not top_level_lookup_thunk_var.
1719 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
1721 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
1723 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
1725 * eval.c (scm_definedp): Incompatibly changed to be a builtin
1726 Scheme function, instead of syntax. Single argument is now a
1729 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1731 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1732 scm_ra_divide): Properly terminate statements passed as arguments
1733 to IVDEP macros. (Thanks to Bernard Urban.)
1735 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1736 with non-constant sizes. (Thanks to Bernard Urban.)
1738 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1740 It's an "eval closure", not an "eval thunk." A thunk is a
1741 function of no arguments.
1742 * root.h (struct scm_root_state): Renamed
1743 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1744 (scm_top_level_lookup_closure_var): Renamed from
1745 scm_top_level_lookup_thunk_var.
1746 * root.c (mark_root): Uses changed.
1747 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1748 * init.c (scm_start_stack): Uses changed.
1749 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1750 Change scheme-visible name to *top-level-lookup-closure* from
1751 *top-level-lookup-thunk*.
1753 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1755 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1756 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1758 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1760 * gc.c (struct scm_heap_seg_data): Doc fixes.
1762 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1763 sweeping. Then, prepend each segment's free cells to its
1764 freelist, rather than wiping out the old value. (Thanks to Marius
1767 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1768 scm_check_freelist, scm_debug_newcell): New functions and
1769 variables, for debugging freelist problems.
1770 * pairs.h (SCM_NEWCELL): New debugging version added.
1771 * gc.h (scm_debug_newcell): Added extern declaration, used by
1772 debugging version of SCM_NEWCELL.
1774 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1776 On some systems <libc.h> conflicts with <unistd.h>, and should not
1777 be #included at all.
1778 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1779 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1780 * configure.in: Call it.
1781 * posix.c, filesys.c: Use its results to decide whether or not to
1783 * configure, scmconfig.h.in: Rebuilt with autoconf and
1786 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1788 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1789 pointer to the stdio stream before calling scm_setbuf0, so the
1790 latter will be able to retrieve it. I'm surprised this didn't
1791 segfault earlier. (Thanks to Christopher Lee.)
1793 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1795 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1798 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1800 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1801 number of stack narrowing specifier pairs. The first specifier in
1802 a pair controls inner border, the second the outer border. A
1803 number means cut that number of frames, a procedure object means
1804 cut until that object is found in operator position in a frame.
1806 * root.c (cwdr): Bugfix.
1808 * read.c: Recording of positions disabled by default.
1810 * procs.c (scm_closure_p): New function.
1812 * posix.c (scm_tmpnam): New function.
1814 * load.c: Added #include "throw.h".
1815 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1818 * load.c, load.h (scm_read_and_eval_x): New function.
1820 * eval.c: Renamed debug option "deval" to "debug".
1822 (scm_eval_x): `eval!' is no longer accessible from the scheme
1823 level. Motivation: We can't allow operations which introduce
1824 glocs into the scheme level. Guile's type system can't handle
1825 these as data. Use `eval' or `read-and-eval!' as replacement.
1827 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1828 SCM_CONSP since this is a macro!; Set vframe.prev to
1829 scm_last_debug_frame instead of 0. In this way we can look
1830 "above" the virtual start stack frame if we wish.
1831 (scm_debug_hang): New function: Useful for debugging Guile in
1832 certain tricky situations. Will probably be removed later...
1834 * debug.h: Changed semantics of debug option "backtrace". This
1835 option now only indicates whether we want automatic backtrace at
1838 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1840 * ports.c: #include "filesys.h"
1841 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1843 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1844 Motivation: This is system specific code which is related to file
1845 I/O. It also may use select. Added code by Gary Houston to
1846 detect presence of character in stdio buffers.
1848 * libguile.h: #include "libguile/libpath.h"
1850 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1851 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1852 SCM_SITE_DIR; Install libpath.h among the other include files.
1854 * load.c, load.h (scm_sys_package_data_dir): New function.
1856 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1858 * stacks.h: Bugfix: Don't use tail-array length field as stack
1859 length field! This screwed GC.
1861 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1863 * _scm.h: Added #ifndef around definition of macros min and max.
1865 * __scm.h: Added hooks for threads to plugin to in ints protection
1866 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1867 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1868 the main code in these macros duplicated and spread over multiple
1869 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1870 SCM_THREAD_SWITCHING_CODE.
1872 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1874 * snarf.h: New file.
1875 * guile-snarf.sh: New file.
1876 * Makefile.in (inner_h_files): Added snarf.h
1877 (ancillary, install, uninstall, distclean): Added actions for
1879 (.c.x): Use guile-snarf.
1880 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1881 (gen_c_files): Note that these depend on guile-snarf.
1882 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1883 now in "snarf.h". Added #include "snarf.h" to get them.
1884 * libguile.h: Added #include "snarf.h".
1885 (Patches applied and tweaked by Jim Blandy.)
1887 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1889 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1890 standards suggest against providing prototypes for system
1891 functions. Thanks to Greg Troxel.
1893 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1895 * strports.c (scm_eval_0str): New function.
1896 #include "read.h", to get prototype for scm_read.
1897 * Makefile.in (strports.o): Update dependencies.
1898 * strports.h: New prototype.
1900 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1901 scheme name from "int?" to "integer?". It seems to do the job.
1902 * numbers.h: Rename prototype too.
1903 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1906 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1907 scm_num_eq_p): Rename these according to R4RS conventions: call
1908 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1909 to making libguile R4RS compliant without ice-9...
1911 * load.c (scm_sys_search_load_path): Search for files under all
1912 extensions listed in the %load-extensions variable. If FILENAME
1913 is absolute, return it unchanged, without searching the load path.
1914 (scm_loc_load_extensions): New variable, pointing to
1915 %load-extensions' value cell.
1916 (scm_init_load): Initialize it, and the value it points to.
1917 (scm_primitive_load_path): Improve error reporting.
1919 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1920 of new Scheme variable %load-hook.
1921 (scm_primitive_load): Apply %load-hook to filename.
1923 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1925 * configure.in: add tests for figuring out whether buffered data
1926 is available in a FILE structure, which is needed by char-ready.
1928 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1931 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1932 exceptions using misc_error instead of syserror. It seems a bit
1933 odd to throw an exception if a string can't be found in the
1934 environment, but it's consistent with open-file, stat etc.
1935 (simpos.h): remove sys_ from getenv.
1937 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1938 occurs, throw an error instead of returning errno. Return value
1940 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1942 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1944 * filesys.c (scm_stat2scm): derive file type and permissions from
1945 the stat mode and append them to the returned vector.
1946 There isn't much overhead in doing this and it avoids the need to
1947 work with S_IRUSR et al. in Scheme.
1948 Define symbols scm_sym_regular etc.
1949 (scm_init_filesys): don't intern S_IRUSR etc.
1951 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1952 and s_primitive_load_path.
1954 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1956 * error.h: don't declare error symbols. prototype for scm_misc_error.
1958 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1961 * error.c: use SCM_SYMBOL to set up error keys.
1962 scm_misc_error: new procedure.
1964 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1966 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1967 between `#!' and `!#' is ignored.
1968 (skip_scsh_block_comment): New function.
1970 * feature.c (scm_set_program_arguments): New argument, FIRST.
1971 * feature.h: Update prototype.
1972 * init.c (scm_boot_guile_1): Pass new argument to
1973 scm_set_program_arguments.
1975 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1977 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1978 (scm_boot_guile): Call scm_set_program_arguments here, later than
1979 the old initialization.
1981 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1982 initialization procedure.
1983 - Delete in, out, err arguments; there are other perfectly good
1984 ways to override these when desired.
1985 - Delete result argument; this function shouldn't ever return.
1986 - Rename init_func argument to main_func, for less confusion.
1987 - Delete boot_cmd argument; main_func is more general.
1988 -Add 'closure' argument, to help people pass data to main_func
1989 without resorting to global variables.
1990 - Abort if reentered; don't bother returning an error code.
1991 - Call scm_init_standard_ports to set up the default/current
1992 standard ports; no need to pass them to scm_start_stack.
1993 - Remove code to evaluate the boot_cmd, and start the repl; let
1994 the user do something like that in main_func if they want.
1995 - Remove code to package up a return value; main_func can do any
1997 - Call exit (0), instead of returning.
1998 (scm_start_stack): Don't initialize the I/O ports here; that's
1999 weird. Delete in, out, err arguments. Move guts to
2000 scm_init_standard_ports, scm_stdio_to_port.
2001 (scm_init_standard_ports): New function, to set up current and
2002 default standard ports.
2003 (scm_start_stack, scm_restart_stack): Make these static.
2004 * init.h (scm_boot_guile): Adjust declaration.
2005 (scm_start_stack, scm_restart_stack): Remove externally
2006 visible declarations for these.
2007 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
2009 * fports.c (scm_stdio_to_port): New function. Its guts used to be
2010 written out several times in scm_start_stack.
2011 * fports.h: New declaration for the above.
2013 * feature.c (scm_set_program_arguments): New function.
2014 * feature.h: New declaration for the above.
2016 * ports.c: Formatting tweak.
2018 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
2020 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
2021 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
2022 for obtaining the address of a car or cdr field. Motivation:
2023 &SCM_CXR make assumptions about the internal structure of the
2026 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
2027 Motivation: see SCM_CXRLOC.
2029 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
2030 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
2031 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
2032 Motivation: Safer use. Some other macros are defined in terms of
2033 these operations. If these are defined using the SCM_SETCXR
2034 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
2035 to inefficiency and an <e1> with side-effects could potentially
2036 break. Also, these particular operations are heavily utilized in
2037 the garbage collector. In unoptimized code there will be a
2040 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
2041 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
2042 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
2043 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
2044 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
2045 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
2046 vports.c: Cleaned up use of pairs: Don't make any special
2047 assumptions about the internal structure of selectors and
2048 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
2049 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
2050 (Among other things, this change makes it easier to build Guile
2051 with certain compilers which have problems with casted lvalues.)
2053 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2055 * stacks.c: Improve selection of relevant stack frames when making
2056 a stack object. Introduce one level of indirection in the stack
2057 object to make it possible to "narrow" to a certain region of the
2058 stack. This facilitates making use of more clever algorithms (not
2059 implemented) for selecting relevant frames and gives a cleaner
2060 design since selection of frames can be done independently of
2061 extraction of frames from the real stack.
2062 (scm_stack_id): Also take #t as argument which means look at
2065 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
2066 Turn n_tail into an integer directly representing current number
2067 of frames in stack. Add field tail.
2069 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
2071 * debug.c (scm_make_memoized): Made it available at scheme level.
2072 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
2073 SCM_NIMP before applying heavier predicates in argument checking.
2074 (scm_local_eval): Also take memoized object as argument.
2076 * backtrace.c (scm_display_error): Just a safety measure: Stacks
2077 aren't created with zero length, but should such a strange
2078 creature suddenly turn up...
2080 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
2082 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
2083 `del', for the sake of C++ compilers. (Patch applied by JimB.)
2085 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
2087 * variable.c (scm_make_variable): Make the name hint optional, as
2089 (anonymous_variable_sym): Renamed from variable_sym. All uses
2092 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
2093 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
2094 of scm_primitive_load_path was also changed to
2095 "primitive-load-path", from "%try-load-path". Callers changed.
2096 We'd like to respect the convention that a function named
2097 "try-mumble" should behave just like the function called "mumble",
2098 but return #f instead of signalling some error.
2099 * load.h: Rename prototypes.
2101 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2103 * print.c (make_print_state, grow_print_state), print.h: Modified
2104 the print state representation: Don't use a tail array for
2105 recording of circular references. Resizing of the print state
2106 structure invalidates the print state pointer. To avoid passing
2107 around an indirect print state reference to all printing
2108 functions, we instead let the print state reference a resizable
2111 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2113 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
2114 Don't crash when passed an improper list terminated by a
2115 non-immediate value.
2117 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
2119 Allocate data for structures on an eight-byte boundary, as
2120 required by the tagging system.
2121 * struct.c (alloc_struct): New function.
2122 (scm_make_struct, scm_make_vtable_vtable): Call it.
2123 * struct.h (scm_struct_n_extra_words): Bump to 3.
2124 (scm_struct_i_ptr): New "field".
2125 * gc.c (scm_gc_sweep): When we need to free the data, use the
2126 information stored by alloc_struct to find the beginning of the
2127 block allocated to the structure, so we can free it.
2129 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2131 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
2134 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
2135 (scm_debug_info): New member: id.
2137 * stacks.c: Stacks are now represented as structs; Stacks have an
2138 id given to them by `start-stack'.
2139 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
2141 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
2142 Changed stack representation.
2144 * debug.c (scm_procedure_name): Try procedure property `name' for
2145 compiled closures aswell.
2147 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
2149 * eval.c: scm_i_name moved to gsubr.c
2150 (scm_m_define): Record names of all kinds of procedure
2151 objects. (Earlier, only closures were recorded.)
2153 * procprop.h: Added declaration of scm_i_name.
2155 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
2156 (scm_make_gsubr): Record names of compiled closures.
2158 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2160 * debug.c, debug.h: Removed obsolete code.
2162 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
2163 stacks.c: Renamed regs --> scm_contregs.
2165 * print.c (scm_free_print_state): Cleanup print state before
2166 returning it to pool. It is better to do it here than in
2167 scm_prin1 since scm_prin1 is called often.
2169 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
2170 s_set_source_property_x): Check that first argument is a pair or a
2173 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
2174 scm_i_line, scm_i_column and scm_i_breakpoint global.
2176 * init.c: Added #include "backtrace.h" and #include "stacks.h".
2177 (scm_boot_guile_1): Added calls to scm_init_backtrace and
2180 * debug.h: Added debug object smob declaration and macro
2183 * configure.in: Build with backtrace.o and stacks.o if debug
2186 * Makefile.in: Added entries for new files: backtrace.c,
2187 backtrace.h, stacks.c and stacks.h.
2189 * symbols.c (scm_sym2ovcell): Fixed documentation.
2191 * _scm.h (min, max): Added.
2193 * async.c: Moved `min' macro to _scm.h.
2195 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
2196 SCM_BACKTRACE_INDENT.
2198 * eval.c: Added new debug options `maxdepth' and `indent'.
2200 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
2202 * print.h: Added selector SCM_PRINT_STATE.
2204 * print.c: New functions: scm_make_print_state,
2205 scm_free_print_state.
2207 * print.h: Added declarations for scm_make_print_state,
2208 scm_free_print_state.
2210 * debug.c (scm_m_start_stack): New acro.
2212 * debug.h: Small cleanup.
2214 * init.c (scm_boot_guile_1): Moved scm_init_debug below
2217 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

2237 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
2238 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
2239 declare functions with prototypes. (Patch thanks to Marius
2242 More prototype-related changes from Marius Vollmer:
2243 * gdb_interface.h: Wrapped header file in #ifdef/#endif
2244 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
2245 * ports.h (ptobfuns): Added prototypes. This means some casting in
2247 * fports.c: Added casts for initializations, since the functions
2248 are defined to take FILE * as their stream argument, not SCM.
2249 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
2250 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
2251 to `char *str_data' to conform to prototype.
2253 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2255 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
2257 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
2259 * stime.c, stime.h: use SCM_P method.
2261 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2263 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
2264 be given at least two arguments. Insist that lst's last element
2265 be a list, but don't make any requirements of its predecessors.
2267 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2269 * eval.c (scm_nconc2last): Revert last change; there seems to be
2270 other stuff going on here.
2272 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2274 * eval.c (scm_nconc2last): Make sure that each element of lst
2275 (which is a list of argument lists, except for the tail) is a
2276 proper list, i.e., finite and terminated by '().
2278 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2280 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
2283 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
2284 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
2287 * vectors.c (scm_make_vector): Fill vectors with the undefined
2288 value, to help make Guile Scheme code more portable to other
2291 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
2292 * symbols.h, tags.h: Doc fixes.
2294 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
2296 * async.c (scm_take_signal): Doc fixes.
2298 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
2300 * numbers.c (scm_divbigint): When the remainder is zero, we don't
2301 want to subtract it from the modulus; we just want to leave it
2304 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
2306 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
2309 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
2311 * throw.c (scm_catch_apply): Finished implementation of
2314 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2316 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
2318 (scm_init_filesys): set "i/o-extensions" feature.
2321 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
2323 * Makefile.in (root.o): Correct dependencies.
2325 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
2327 * Makefile.in: Added dependency entry for root.o.
2329 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
2330 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
2332 * init.c (scm_start_stack): Set initial root continuation number
2335 * procs.c: New function: scm_thunk_p.
2337 * procs.h: Added declarations of scm_thunk_p.
2339 * root.c: Renamed `call-with-new-root' -->
2340 `call-with-dynamic-root'.
2341 (cwdr): Removed allocation of new root state. This should be done
2342 separately by use of scm_make_root.
2343 (scm_apply_with_dynamic_root): New function: Does what it
2344 sounds like. Needed when spawning threads.
2346 * root.h: Added member last_debug_frame to root state.
2347 Added #include "libguile/debug.h"
2349 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
2350 arguments. The motivation is that code in root.c needs catch
2351 functionality, and we want to avoid code duplication.
2352 New functions: scm_catch, scm_lazy_catch. These are wrappers for
2353 scm_catch_apply. scm_lazy_catch is intended to introduce catch
2354 handlers that run without popping the stack into the dynwind
2357 * throw.h: Added prototypes for scm_catch_apply and
2360 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2362 * root.h (scm_root, scm_set_root): Decouple thread support details
2363 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
2364 SCM_SET_THREAD_LOCAL_DATA.
2366 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
2367 and tortoise scanning loop.
2369 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
2371 * Makefile.in: Rebuild dependencies.
2373 * libguile.h: #include "libguile/print.h" before "smob.h", since
2374 the latter uses the print_state structure.
2376 * throw.c (scm_ithrow): Use the correct variable when checking to
2377 see if a given element of scm_dynwinds is a valid catch.
2379 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
2380 structure, abort; don't just silently ignore the garbage.
2382 * _scm.h: #include "print.h" here, since it seems to be used just
2384 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
2385 strports.c, unif.h: Don't #include "print.h".
2387 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2389 * feature.h (scm_loc_features): Removed external declaration.
2390 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
2392 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2394 * feature.c (scm_init_feature): Added threads feature (needs to be
2395 initialized here, since features doesn't exist when
2396 scm_init_threads is called).
2398 * libguile.h: Added #include "libguile/../threads/threads.h".
2399 (This is a kludge to get thread support working. This should be
2402 * configure.in, acconfig.h: Added flags for thread support.
2404 * scmsigs.c: Define `signal' to be `pthread_signal' if using
2407 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
2408 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
2411 * _scm.h: Added conditional #include "threads.h"
2413 * __scm.h (SCM_ASYNC_TICK): Added call to macro
2414 SCM_THREADS_SWITCHING_CODE.
2416 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
2417 allocate the basic dynamic root object.
2418 (scm_boot_guile): Added call to scm_init_root.
2420 * root.c, root.h: Added root smob.
2421 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
2422 functions: Implements dynamic roots mostly according to spec in
2423 SCM manual. Main difference is that the second argument is a
2424 throw handler rather than an error "thunk".
2426 * root.h: Added declaration of scm_init_root.
2428 * root.c: Added #include "genio.h", #include "smob.h", #include
2429 "pairs.h", #include "throw.h", #include "dynwind.h", #include
2431 (scm_init_root): Added #include "root.x".
2433 * throw.c: Added #include "stackchk.h"
2434 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
2435 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
2436 can be used in scm_call_with_new_root; Added reenabling of stack
2437 checking when catching a throw.
2439 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
2441 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
2443 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
2444 element is not found, as per R4RS.
2446 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2448 * list.c: Doc fixes throughout.
2450 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2452 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
2453 declare the char * to be const. Avoids a warning in rgx.c.
2455 * ports.h: spelling fix.
2457 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
2460 * load.c (scm_sys_try_load_path): throw an error if file not found
2461 (like it says it in NEWS).
2463 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2465 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
2466 PROPS slot to '(), not #f; it's an empty alist.
2468 * throw.h, throw.c: Use SCM_P instead of #if hair.
2470 Remove special support for uncaught throws; see throw.c for
2472 * throw.c (uncaught_throw): New function.
2473 (scm_ithrow): Call uncaught_throw if we don't find a throw
2474 target; don't mess with scm_bad_throw_vcell.
2475 (scm_bad_throw_vcell): Variable deleted.
2476 (scm_init_throw): Don't initialize it.
2478 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
2481 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2483 * numbers.c (scm_istr2int): If the number is short (as most
2484 numbers are), just call scm_small_istr2int to deal with it.
2485 (scm_small_istr2int): New function, created by un-#ifdefing the
2486 non-bignum version of scm_istr2int and renaming it.
2488 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
2490 * load.c (scm_sys_try_load): don't check whether value returned
2491 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
2492 Change the Scheme name from %try-load to primitive-load.
2494 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
2495 Can avoid passing a message, allowing it to be derived in the
2496 error handler (e.g., if we want to throw to the key both from
2499 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
2501 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
2502 references now have a new appearance which is more compact and
2503 also gives a clue about what the target of the reference is.
2504 By setting parameters in the print state, more fancy printing can
2505 be achieved. This is used by the (not yet commited) backtrace
2508 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
2510 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
2513 * print.c: Added #include "struct.h". Removed function
2516 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
2517 scm_iprin1. Removed prototype for scm_prlist.
2519 * arbiters.c (prinarb),
2520 async.c (print_async),
2521 debug.c (prindebugobj, prinmemoized),
2522 eval.c (prinprom, prinmacro),
2523 filesys.c (scm_fd_print, scm_dir_print),
2525 mallocs.c (prinmalloc),
2526 numbers.c, numbers.h (scm_floprint, scm_bigprint),
2527 smob.h (scm_smobfuns),
2528 srcprop.c (prinsrcprops),
2530 unif.c, unif.h (scm_raprin1, rapr1),
2531 variable.c (prin_var): Changed argument `int writing' to
2532 `scm_print_state *pstate'.
2534 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
2535 that it will be called before scm_init_print.
2537 * print.c (scm_prin1): Print states are now allocated when calling
2538 scm_prin1 and then passed around to all printing functions as an
2539 argument. A cache `print_state_pool' enables reuse of print
2541 (scm_make_print_state): New function.
2542 (scm_iprin1): Adaption to print states.
2543 (scm_iprlist): An initial "hare and tortoise" scan brings down
2544 time complexity to O (depth * N). (Better time complexity will be
2545 achieved when the printing code is completely rewritten.)
2547 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2549 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
2550 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
2551 it gets done whether or not the cache variable has a value.
2553 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2555 Distinguish #f and ().
2556 * __scm.h: #undef SICP.
2557 * pairs.h (SCM_EOL): Delete this definition, equating it with
2559 * tags.h (SCM_EOL): Give it a new definition here; I think I found
2560 the value it used to have. Doc fixes, too.
2562 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
2564 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
2565 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
2566 Lord's implementation of structs, allowing for tail arrays as
2567 described in the manual. Also fixed some bugs. (Both the interface
2568 and the implementation should be improved.)
2570 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
2572 * print.c, print.h: Closures now print like #<procedure foo (x)>.
2573 People who whish to see the source can do `(print-enable 'source)'.
2574 Removed #ifdef DEBUG_EXTENSIONS.
2576 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2578 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
2579 integer (assuming for now accepting an integer is a good thing).
2581 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2582 %S will be used instead for write'ing arguments.
2584 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2585 asserts. fix a few other asserts.
2586 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2587 scm_uniform_vector_ref, scm_array_set_x,
2588 scm_dimensions_to_unform_array): change args in
2589 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2590 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2591 scm_substring_fill_x): likewise.
2592 gsubr.c (scm_gsubr_apply): likewise.
2593 eval.c (SCM_APPLY): likewise.
2595 * eval.c (4 places): replace scm_everr with lgh_error or
2598 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2599 scm_memory_error): new procedures.
2600 scm_everr: deleted. can use scm_wta, dropping first two args.
2601 scm_error: convert NULL subr to SCM_BOOL_F.
2603 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2606 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2609 * error.c, error.h: new error keys: scm_arg_type_key,
2610 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2612 scm_wta: reimplement using lgh_error instead of scm_everr.
2614 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2616 * gdbint.c: scm_lread now has one more argument.
2618 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2619 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2620 loading source from non-file ports, which, e. g., happens when
2621 using the Emacs interface).
2623 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2626 * read.c: Added code for recording of positions of source code
2627 expressions; New functions: recsexpr, scm_lreadrecparen;
2628 _scm_make_srcprops --> scm_make_srcprops
2629 (scm_flush_ws): Removed updating of positions counters. This work
2630 is already done by scm_gen_getc
2632 * read.h: Added prototype for scm_lreadrecparen
2634 * print.c: Added #include "alist.h"
2636 * eval.c: Added #include "hash.h"
2638 * eq.c: Added #include "ramap.h"
2640 * options.c: Documentation fixes.
2642 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
2643 (scm_init_srcprop): Adjusted size of initial source-whash. Name
2644 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2645 --> scm_make_srcprops
2647 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2648 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2649 function calls in the definition of the whash access macros.
2651 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2653 * init.c (scm_boot_guile): Add level of indirection to
2654 scm_boot_guile_1() to ensure that stack base pointer is properly
2655 initialized. There was no guarantee that variable i was the
2656 highest/lowest variable on stack (i.e. the call frame of
2657 scm_boot_guile was not completely protected from gc).
2659 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2661 * ports.h (scm_port_table): put back file_name, it will be used to
2662 support debugging. Undo related changes in fports.c, ioext.c,
2665 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2667 * ports.h (scm_port_table): remove file_name member for now, it seems
2669 * fports.c (scm_open_file): don't set file_name in PTAB.
2670 (prinfport): don't use file_name in PTAB.
2671 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2672 * ports.c (scm_add_to_port_table): don't intialize file_name.
2673 (scm_port_file_name): remove for now.
2674 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2676 * fports.h (scm_mkfile): prototype deleted.
2677 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2679 * debug.c, unif.c: use scm_out_of_range instead of
2680 wta for range errors (ASSERT still needs work).
2682 * error.c, error.h (scm_out_of_range): new procedure.
2684 * error.c, error.h (scm_out_of_range_key): new key.
2686 * posix.c (scm_sync): #else was missing.
2688 * error.c, error.h: append _key to names scm_num_overflow and
2691 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2692 of consing an empty list.
2693 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2694 of macros, saves code and string space.
2695 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2696 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2697 lower case. Rename scm_syserror_m to scm_syserror_msg.
2698 error.h: prototypes for new procedures.
2700 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2702 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2704 * error.c, error.h: setup scm_num_overflow key.
2706 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2707 Remove definition of SCM_OVSCM_FLOW.
2709 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2711 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2712 explicit message and args.
2714 * error.c, error.h, __scm.h: change system_error_sym to
2717 * error.c (system_error_sym): remove leading %% from the Scheme name
2720 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2722 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2724 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2725 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2726 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2727 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2728 renamed. (These were introduced by unsupervised name
2731 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2733 * print.c: Added code for detection of circular references during
2734 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2735 a hook for printing of closures (accessible via print options).
2736 This leads to a split of calls to scm_iprin1 into two classes:
2737 elementary print operations (e. g. the code which prints a smob)
2738 still use scm_iprin1 while top level calls (like scm_display) use
2739 scm_prin1. scm_prin1 begins by clearing the data structure used
2740 to record reference information.
2742 * print.h: Added declarations of scm_prin1 and scm_prlist.
2744 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2746 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2748 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2750 * error.c (err_head): scm_iprin1 --> scm_prin1
2752 * debug.c: Adjusted header comment.
2756 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2758 * strerror.c: Doc fix.
2760 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2762 * gdbint.c (gdb_read): Now possible to run during GC.
2763 (unmark_port, remark_port): New functions.
2765 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2767 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2768 of allocating a new string object. Also, increase size by
2769 the factor 2 instead of 1.5.
2771 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2773 * __scm.h (SCM_P): Corrected to run under traditional C.
2775 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2778 * async.c: Calls to scm_sysintern corrected.
2780 * async.h (scm_async_clock): Redundant declaration removed.
2782 * continuations.c (scm_dynthrow): Redundant declaration removed.
2784 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2785 Definition typos corrected.
2787 * debug.h: Missing declarations of functions in debug.c added
2790 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2791 Missing declarations to functions in eval.c added.
2793 * filesys.c: Possibly uninitialized variable rv.
2795 * gc.h (scm_object_addr, scm_unhash_name): Missing
2796 declarations of functions defined in gc.c added.
2798 * genio.c: Possible typos str_data -> wstr_data. ???
2800 * genio.c: Possibly unintended shadowing of local variable
2801 `int c' (gotos out of scope of inner `c'). ???
2803 * init.c: Uninitialized `SCM last' may be used.
2805 * ioext.h: (scm_sys_isatty_p): Typo.
2807 * list.h (scm_list_head): Missing prototype for function in
2810 * numbers.c (scm_two_doubles): Changed from extern to static
2811 (is used only within numbers.c).
2813 * numbers.h: Repeated declarations removed.
2815 * ports.h (scm_close_all_ports_except): Declaration for the
2816 function defined in ports.c added.
2818 * posix.h: Missing declarations added.
2820 * procs.h (scm_make_subr_opt): Missing declaration added.
2822 * socket.h (scm_sys_gethost): Missing declaration added.
2824 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2826 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2827 Missing declarations added.
2829 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2831 * struct.c: Uninitialized variable `SCM answer' may be used.
2833 * unif.c (l2ra): Declaration prototype.
2835 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2836 defined in ramap.c).
2838 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2839 Redundant declarations removed (they are in ramap.h).
2841 * variable.h (scm_make_udvariable,
2842 scm_make_undefined_variable): Declaration corrected to
2843 correspond variable.c.
2845 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2846 Missing declarations added.
2848 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2850 * Makefile.in (distclean): Don't forget to delete fd.h.
2852 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2854 * fd.h.in, tags.h: Trivial cleanups.
2856 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2857 marksweep.h just declared functions from gc.c.
2858 * gc.h, libguile.h: Don't #include "marksweep.h".
2859 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2860 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2861 dependencies updated.
2863 * libguile.h: Don't #include "files.h"; it's been deleted.
2865 * files.c (scm_sys_delete_file): Moved to filesys.c.
2866 File is now empty; deleted.
2868 * filesys.c: scm_sys_delete_file is now here. Remove
2869 #if's; they seem to rely on remnants of an old portability
2870 regimen. If the problems come up again, solve them properly,
2871 using autoconf. Specifically: Don't test M_SYSV, and #define
2872 remove to be unlink if it's #defined; don't use remove just
2873 because HAVE_STDC_HEADERS is #defined.
2874 * filesys.h: Add declarations for scm_sys_delete_file.
2875 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2876 files.o, files.h, files.c, and files.x.
2877 * init.c: Don't #include "files.h", and don't call scm_init_files.
2879 Use SCM_P instead of PROTO; the latter intrudes on the user's
2881 * params.h: Deleted; definition of SCM_P moved to...
2882 * __scm.h: ... here, where it replaces PROTO macro.
2883 * libguile.h, smob.h: Don't #include "params.h".
2884 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2885 smob.h: Fix prototypes accordingly.
2886 * Makefile.in: Update dependencies.
2887 (inner_h_files): Remove params.h.
2889 * gc.c: #include "gc.h"; every module should include its header,
2890 to let the compiler cross-check the declarations against the
2893 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2894 simpos.h: #include "libguile/__scm.h".
2896 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2898 * init.c: Don't forget to #include smob.h and init.h.
2899 * Makefile.in: Dependencies updated.
2901 * smob.h: Use PROTO instead of #if __STDC__.
2903 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2905 * __scm.h: Doc fixes.
2907 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2908 <angles>; this allows `make depends' to work properly.
2910 * libguile.h: #include smob.h and pairs.h before the others; they
2911 define typedefs used by other headers.
2913 C files should #include only the header files they need, not
2914 libguile.h (which #includes all the header files); the pointless
2915 recompilation was wasting my time.
2916 * Makefile.in (all .o dependency lists): Regenerated.
2917 * libguile.h: Don't try to get a definition for size_t here...
2918 * __scm.h: Do it here.
2919 * _scm.h: Since this is the internal libguile header, put things
2920 here that all (or a majority) of the libguile files will want.
2921 Don't #include <libguile.h> here; that generates dependencies on
2922 way too much. Instead, get "__scm.h", "error.h", "pairs.h",

3021 * weaks.c: Get "weaks.h".
3023 * stackchk.h: #include "libguile/debug.h",
3025 * print.h, read.h: #include "options.h", since everyone who uses
3026 either of these files will need that.
3028 * smob.h: #include "ports.h", "genio.h", and "print.h", since
3029 anyone who uses this file will need them to define the smob
3030 printing functions. Also, get markers.h, since people will need
3031 to #define the mark functions.
3033 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
3034 * ports.h: ... to here.
3036 * ports.h (scm_port_table_size): Explicitly give type as 'int';
3037 don't rely on archaic C default type rules.
3039 * fports.h: #include "libguile/ports.h", since you need that in
3040 order to parse this.
3042 * genio.h: #include "libguile/print.h", because you need that to
3043 parse this; don't bother #including "ports.h", since print.h gets
3046 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
3048 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
3049 this; it's now a reference to an element of *scm_root.
3051 * debug.h: Don't #include "options.h"; the compiler won't be able
3052 to find that once the headers are installed; instead, #include
3053 "libguile/options.h".
3054 * gc.h: Same, with marksweep.h.
3055 * mbstrings.h: Same, with symbols.h.
3056 * scmhob.h: Same, with _scm.h.
3057 * smob.h: Same, with params.h.
3059 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
3060 C files; there's no need for this, and it forces recompilations
3063 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
3065 * error.c (scm_error): declare scm_error_callback.
3067 * error.h: prototype for scm_error_callback.
3069 * __scm.h: define lgh_error.
3070 (SCM_SYSERROR): redefine using lgh_error.
3072 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
3074 * error.c (scm_error): new procedure.
3076 * error.h: prototype for scm_error.
3078 * Makefile.in (install): install scmconfig.h from the current
3079 directory, not $(srcdir).
3081 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3083 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3084 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3085 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
3086 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
3087 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
3088 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
3089 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
3090 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
3091 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3092 vports.h, weaks.h: #include "libguile/__scm.h", not
3093 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
3094 dependencies are within libguile properly.
3096 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3098 * Makefile.in (.c.x): Simplify; there's no need to run this rule
3099 when scmconfig.h doesn't exist.
3101 * load.c (scm_sys_try_load): Correct spelling.
3103 * feature.c (scm_loc_features): Make this static.
3105 * Makefile.in (libpath.h): Omit trailing slash from path. We
3106 shouldn't require it of users, so why put it here?
3108 Move code to initialize and search %load-path from ice-9 to C
3109 code, so we can use the load-path to find the ice-9 boot code;
3110 this makes it easier to run Guile without installing it. See
3111 corresponding changes in guile/Makefile.in.
3112 * feature.c: Move stuff concerned with the load path to load.c.
3113 (scm_compiled_library_path): Deleted.
3114 Don't #include libpath.h here.
3115 * feature.h: Don't mention scm_compiled_library_path.
3116 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
3117 <sys/stat.h>, and <unistd.h> (if present).
3118 (R_OK): #define if the system hasn't deigned to.
3119 (scm_loc_load_path): New variable.
3120 (scm_init_load_path, scm_sys_search_load_path,
3121 scm_sys_try_load_path): New functions.
3122 (scm_init_load): Initialize scm_loc_load_path to point to the
3123 value cell of the Scheme %load-path variable.
3124 * load.h: Add declarations for scm_sys_search_load_path,
3125 scm_sys_try_load_path.
3126 * init.c: Call scm_init_load_path.
3127 * Makefile.in (feature.o, load.o): Dependencies updated.
3129 * load.c, load.h: Rewrite using PROTO macro.
3131 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3133 * gc.c (scm_cellp): New function: C predicate to determine if an
3134 SCM value can be regarded as a pointer to a cell on the heap.
3136 * gc.h: Added declaration of scm_cellp.
3138 * gdb_interface.h: New file: The GDB interface header from the GDB
3141 * gdbint.c: New file: GDB interface.
3143 * gdbint.h: New file: GDB interface.
3145 * libguile.h: Added #include <libguile/gdbint.h>.
3147 * init.c (scm_boot_guile): Added scm_init_gdbint.
3149 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
3150 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
3151 found if object files and source are kept separate).
3153 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
3155 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
3157 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
3159 * configure.in: Don't substitute the values of TCL_SRC_DIR and
3160 TK_SRC_DIR; they're not relevant any more.
3162 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
3163 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
3165 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
3167 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
3168 search path, so we can find the <libguile/MUMBLE.h> headers.
3170 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
3172 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
3173 implicit in the .c.o rule.
3174 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
3177 Put the library path in a header file, instead of passing it on
3178 the command line in every compilation.
3179 * Makefile.in (libpath.h): New target.
3180 (feature.o): Depend on libpath.h.
3181 (clean): Delete libpath.h.
3182 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
3183 * feature.c: ... #include "libpath.h" here.
3184 * .cvsignore: Ignore libpath.h.
3186 Don't install the unwashed masses of Guile header files in the
3187 main #include path; put most of them in a subdirectory called
3188 'libguile'. This avoids naming conflicts between Guile header
3189 files and system header files (of which there were a few).
3190 * Makefile.in (pkgincludedir): Deleted.
3191 (innerincludedir): New variable; this and $(includedir) are enough.
3192 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
3193 (installed_h_files): Divide this up. Now this variable lists
3194 those header files which should go into $(includedir) (i.e. appear
3195 directly in the #include path), and ...
3196 (inner_h_files): ... this new variable says which files appear in
3197 a subdirectory, and are referred to as <libguile/mumble.h>.
3198 (h_files): List them both.
3199 (install): Create innerincludedir, not pkgincludedir. Put
3200 the installed_h_files and inner_h_files in their proper places.
3201 (uninstall): Corresponding changes.
3202 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3203 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3204 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
3205 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
3206 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
3207 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
3208 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
3209 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
3210 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3211 vports.h, weaks.h: Find __scm.h in its new location.
3212 * __scm.h: Find scmconfig.h and tags.h in their new locations
3213 (they're both "inner" files).
3215 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
3217 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
3219 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3221 * posix.c: Doc fixes.
3223 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
3225 * socket.c: Don't include a prototype for inet_aton; just use a
3226 K&R style declaration, to avoid warnings but minimize the chance
3227 of conflicts with the system.
3229 On NextStep, <utime.h> doesn't define struct utime, unless we
3230 #define _POSIX_SOURCE before #including it.
3231 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
3232 * acconfig.h: New comment text for above CPP symbol.
3233 * configure.in: Call it.
3234 * posix.c: #define _POSIX_SOURCE if it seems necessary.
3236 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
3238 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
3239 testing for __EMX__.
3241 * posix.c: #include <libc.h>, if it exists.
3243 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
3244 don't even know if the latter exists.
3246 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
3247 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
3248 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
3250 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
3252 (scm_init_posix): Use them when initializing the Scheme constants
3255 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3257 * Makefile.in (libdir, includedir, bindir): Use the
3258 autoconf-supplied values, instead of deriving them ourselves.
3259 (pkgincludedir, datadir, pkgdatadir): New variables.
3260 (install, uninstall): Put the header files in a special
3261 subdirectory, not in the main search path.
3263 * Makefile.in (ALL_CFLAGS): Provide the proper value for
3264 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
3266 * Makefile.in (IMPLPATH): Deleted; never used.
3268 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
3269 on the Tcl/Tk source any more.
3270 (INCLUDE_CFLAGS): Remove references to the above.
3272 * Makefile.in (version.o): Corrected dependencies.
3274 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
3276 * libguile.h: #include "version.h"
3278 * init.c (scm_boot_guile): Call scm_init_version.
3279 * gscm.c (gscm_run_scm): Call scm_init_version.
3281 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
3282 GUILE_VERSION): AC_DEFINE these.
3283 (acconfig.h): #undef the above symbols.
3285 * Makefile.in (libobjs): Add version.o.
3286 (installed_h_files): Add version.h.
3287 (c_files): Add version.c.
3288 (gen_c_files): Add version.x.
3289 (version.o): New rule.
3290 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
3291 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

3299 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
3300 weaks.o): Add version.h to dependency lists.
3301 (markers.o): Remove duplicate rule.
3303 * version.h: New file.
3305 * version.c: New file.
3307 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3309 * symbols.c (scm_strhash): scm_downcase is now a function, not an
3310 array; use it appropriately. Since GCC is quite happy to
3311 subscript functions, it never warned us about this; we should use
3312 -Wpointer-arith in the future. I guess we never tested
3315 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3317 * socket.c: Doc and copyright fixes.
3319 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3321 * debug.c: Fixed and improved gdb support.
3323 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3325 * socket.c: Added declaration of inet_aton to avoid compiler
3326 warning. (Hope this solution is correct.)
3328 * stime.c: Added declaration of ftime. (This is missing in
3331 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
3333 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3335 * Makefile.in (c_files): add strerror.c.
3337 * strerror.c: new file from Emacs' sysdep.c.
3338 maybe configure should also check for sys_errlist.
3340 * configure.in (AC_REPLACE_FUNCS): add strerror.
3342 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3344 * debug.c (scm_init_debug): Added initialization for
3345 scm_evaluator_traps.
3347 * debug.h, debug.c: Various name changes.
3348 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
3349 "debug-options-interface". See commentary in options.c.
3351 * options.h, options.c: Options now have documentation strings.
3352 Also added a long explanatory commentary.
3354 * eval.c, print.h, print.c, read.h, read.c: Modifications to
3357 * gscm.c, init.c, root.c, throw.c: Bug fixes:
3358 last_debug_info_frame is now updated in all cases.
3360 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
3363 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3365 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
3366 Added option STACK_CHECKING.
3368 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3370 * Makefile.in: Added {debug,options,srcprop}.{h,c}
3372 * __scm.h: Removed symbols for debugging support.
3374 * acconfig.h: Added symbols for debugging support.
3376 * configure.in: Added user option for debugging support.
3377 --enable-debug will include the debugging code into libguile.a.
3379 * continuations.c (scm_make_cont): Enlarged the #if 0 around
3380 scm_relocate_chunk_to_heap.
3382 * debug.c: New file: low-level debugging support. It also
3383 includes support for debugging with gdb. (The extensions to gdb
3384 are written by Per Bothner at Cygnus.)
3386 * debug.h: New file: low-level debugging support.
3388 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
3389 argument pairs. Extensive modifications to the debugging
3390 evaluator. Added "SECTION:" commentaries to clarify what happens
3391 when, during double compilation. Renamed EVALIMP --> EVALIM.
3392 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
3393 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
3394 the beginning of the file. New procedure: scm_unmemocopy.
3395 Added some global state variables needed by the debugging
3396 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
3397 check_entry, check_apply, check_exit, debug_options and
3398 evaluator_traps. New acro: undefine.
3400 * eval.h: Renamed EVAL --> XEVAL.
3402 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
3403 --> scm_make_weak_key_hash_table.
3405 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
3406 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
3408 * libguile.h: Conditionally include debug.h
3410 * objprop.c (scm_object_properties, scm_set_object_properties_x):
3411 scm_object_properties shouldn't return handle. `handle' now gets
3412 initialized in scm_set_object_properties_x. scm_object_properties
3413 doesn't any longer create an entry in scm_object_whash.
3415 * options.c: New file: handling of run time options.
3417 * options.h: New file: handling of run time options.
3419 * posix.c (scm_getpgrp): Cast pointer to getpgrp.

3440 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3442 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
3444 * libguile.h: #include "objprop.h"; I guess this was forgotten.
3446 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
3447 and should be called by the final client.
3449 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
3451 * gc.h: Use the PROTO macro when declaring functions.
3452 * gc.c: Use the PROTO macro when declaring static functions.
3453 Remove the CPP hair around function definitions.
3455 * gc.c (scm_init_storage): Initialize scm_asyncs.
3457 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
3458 preprocessor symbol; "__scm.h" is where it might get #defined.
3459 * __scm.h: Similar: #include <scmconfig.h> before testing
3462 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
3464 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
3466 * init.c (scm_boot_guile): Add init_func argument; call
3467 (*init_func) instead of calling scm_appinit; it's ucky to
3468 hard-code names for the user's procedures.
3469 * init.h (scm_boot_guile): Adjust declaration.
3471 * __scm.h (PROTO): New macro, for declaring functions with
3474 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
3475 eliminate all the __STDC__ conditionals.
3476 (scm_boot_guile): Add declaration.
3477 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
3478 Remove __STDC__ conditionals around function definitions; the
3479 declarations in init.h will provide the same information, more
3482 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
3483 complain about it in the error message; the error message is
3484 adequate without that note, and there's nothing the user can do
3487 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
3489 * Makefile.in (ancillary): Drop def.sed.
3491 * posix.c (scm_init_posix): Use numeric values, rather than
3492 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
3493 F_OK. The symbols aren't available on some systems, and I'm
3494 pretty sure their values are fixed by common widespread practice.
3495 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
3497 More functions unavailable on some systems.
3498 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
3499 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
3501 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3502 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
3503 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
3504 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
3505 stub that signals an error as the #else.
3507 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
3509 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
3511 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
3513 * unif.c: include ramap.h.
3515 * read.c (endif): case_insensative_p renamed case_insensitive_p.
3517 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
3519 * ports.c: include sys/ioctl.h.
3521 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
3523 * configure.in: check for sys/ioctl.h.
3525 * ports.c: include <malloc.h> not "malloc.h".
3527 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3529 * fports.c: remove ttyname and tmpnam declarations.
3531 * posix.c: fewer ttyname declarations.
3533 * fports.c: include <string.h> not "string.h".

3537 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3539 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
3540 genio.c, simpos.c, vports.c: include string.h.
3542 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
3544 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
3546 (scm_addr_buffer_size): change type from scm_sizet to int.
3547 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
3548 from scm_sizet to int.
3550 * error.c: include unistd.h.
3552 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
3555 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
3557 * __scm.hd, def.sed: deleted.
3559 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
3561 Changes for NeXT, suggested by Robert Brown.
3562 * configure.in: Call AC_TYPE_MODE_T.
3563 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
3564 NeXT. Put header file list in alphabetical order.
3565 * configure, scmconfig.h.in: Regenerated.
3566 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
3568 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
3571 * acconfig.h: New file, providing documentation for the CPP
3572 symbols defined in configure.in
3573 * acconfig-1.5.h: Removed; superceded by the above.
3575 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
3577 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
3579 * fports.c (scm_open_file): don't return #f, throw error.
3581 * ioext.c (fileno): renamed from %fileno.
3582 (soft-fileno): deleted.
3584 * ports.c (scm_port_revealed): don't need to check for -1 from
3586 (scm_set_port_revealed_x): return unspecified, not #f.
3588 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
3590 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
3592 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
3594 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
3596 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3598 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
3599 This is necessary on Ultrix, and doesn't hurt portability.
3601 * Makefile.in (dist-dir): New target, implementing a new dist system.
3602 (installed_h_files): Put in alphabetical order.
3603 Remove duplicate entries for markers.h and unif.h.
3604 (c_files): Remove duplicate entries for markers.c.
3605 (ancillary): Renamed from anillery; all uses changed. Remove
3606 PLUGIN; it's a directory, and needs special treatment in dist-dir.
3607 Remove all the ../doc/* files; doc/Makefile.in handles that.
3609 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3611 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3612 every if must have an else, or else the whole command has a
3613 non-zero exit code whenever the if's condition is false.
3615 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
3617 * posix.c: include string.h.
3619 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3621 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
3624 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
3625 Remove leading % from scheme names.
3626 Do not return error values, call SCM_SYSERROR or similar.
3628 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
3630 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
3632 * struct.c (scm_init_struct): new file.
3634 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
3636 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
3637 (scm_list_head): added list-head for rapidly chopping argument
3638 lists off of longer lists (and similar).

3647 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
3648 weak hash tables last of all marking to avoid an obscure gc bug.
3649 WARNING: circular lists stored in a weak hash table will hose us.
3651 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
3653 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
3654 new functions similar to scm_substring_move_left_x and
3655 scm_substring_move_right_x.
3657 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
3659 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
3662 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
3664 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
3666 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
3668 * strports.c (scm_strprint_obj): convenience function. C for
3669 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
3671 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
3672 removed to a separate library
3674 * init.c (scm_boot_guile): copied from guile-tcl.c.
3675 Initialization specific to tcl interpreters removed.
3677 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
3679 * ports.c (scm_ports_prehistory): size malloced here doesn't
3680 matter so long as it is non-0 (got rid of "* 4").
3682 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3684 * gscm.h: gscm_mkarray eliminated (presumably was not being used
3685 since its definition was bogus).
3687 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
3689 * mallocs.[ch]: back again (for rx at least).
3691 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
3693 * ports.c: removed functions relating to the mapping between ports
3694 and descriptors. (That stuff is unix-specific and should be collected
3695 in a separate library).
3697 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
3698 (Tom Mckay@avanticorp.com)
3700 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
3702 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3703 handled correctly (SCM_FREEP was applied to them) -- test for
3704 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
3705 being overwritten with #f. (brown@grettir.bibliotech.com)

3736 * procprop.c (scm_stand_in_scm_proc):
3737 NOTE: don't use a alist here.
3738 (scm_set_procedure_properties_x): fix type checking throughout this file.
3740 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
3742 * ports.c (scm_remove_from_port_table): adjust scm_mallocated

3748 * vports.c (scm_make_soft_port): allocate a port table entry
3749 (possibly triggering gc) before setting the tag of the corresponding
3752 * pairs.c (scm_delq_x): never throw an error.
3754 * vectors.c (scm_make_vector): made the default vector fill argument
3755 into '() (much more useful than the previous value, "#unspecified")
3757 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
3759 * ports.c (scm_add_to_port_table): Added fields
3760 to port table entries: file_name, line_num, col.
3761 Update these in open_file, gen_getc and gen_ungetc.
3762 Added procedures to access those fields.
3764 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
3766 * procs.c (scm_make_subr_opt): new entry point for making
3769 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
3771 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
3773 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
3775 * numbers.c (scm_exact_p): This function no longer
3776 implements "integer?".
3778 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
3780 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
3781 (scm_gc_stats): return an assoc of useful data. Replaces "room"
3782 and the stats reporting formerlly built into repl.
3784 * repl.[ch]: removed.
3785 GC statistics keeping moved to gc.c.
3786 Other statistics keeping can be done from Scheme.
3787 REPLS are now written in Scheme.

3794 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
3796 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
3798 * feature.c (scm_compiled_library_path): moved here from repl.c.
3799 This file is for stuff relating specifically to Scheme libraries
3802 * eval.c (scm_m_define): don't give warning about redefinition, don't
3805 NOTE: this should throw a resumable exception with parameters --
3806 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
3808 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.

3822 between the call to procedurep and use.
3824 * error.c (scm_everr):
3826 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,

3830 because it changes size.
3832 (stputc stwrite): check/change the strings length with interrupts

3839 (per suggestion jaffer@gnu.ai.mit.edu).
3841 * mbstrings.c (scm_multi_byte_string): guard against argument list
3844 * strings.c (scm_make_string): loop cleanup
3846 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer

3872 initialization to fix a race condition.
3874 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

3897 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
3898 set the multi_byte flag correctly in symbols. This is wrong.
3899 intern_obbary_soft and msymbolize should take an extra parameter.
3900 Also, weird multibyte symbols don't print correctly.
3901 The weird symbol syntax is also a bit bogus (emacs doesn't quite
