1 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
3 * guile-snarf.in: Changed regexp to support CPPs that insert
4 whitespace between lexical tokens (which munges the `%%%' snarf
7 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
9 * * load.c (scm_init_load_path): Append $(datadir)/guile to
10 %load-path, so modules do not have to be installed in Guile's
11 current version directory.
13 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
15 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
16 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
17 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
18 call the sysdep functions with deferred ints.
19 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
20 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
21 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
24 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
27 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
29 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
31 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
33 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
36 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
38 * eval.c (scm_lookupcar1): New procedure to cope with a race
39 condition during lookup (when using threads).
40 (scm_lookupcar): Implement in terms of scm_lookupcar1.
41 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
44 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
46 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
47 supplied. (Change from Tim Pierce.)
49 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
51 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
52 23:47:01 1997" changelog: Slots are now initialized with `#f' by
53 default and not `()'. `#f' is the canonical non-value in Scheme,
56 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
58 * struct.c (struct_printer): New variable that holds a handle on
59 the Scheme variable *struct-printer*. This variable can be set by
60 Scheme code to override the printing of structures.
61 (scm_print_struct): If struct_printer is set, call it. If it is
62 not set, or returns #f, print the structure in the old fashion.
63 Include "eval.h" for scm_apply.
65 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
67 * struct.c (scm_struct_ref, scm_struct_set_x): Use
68 scm_struct_i_n_words to get the number of fields, not
69 -scm_struct_n_extra_words.
71 On the route to fancier struct printing:
72 * struct.c (scm_print_struct): New function to print a structure.
73 Include "genio.h" to support it. This function doesn't do
74 anything interesting right now, but I think it should be here
76 * struct.h: Include "print.h" and add prototype for
78 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
79 print structures ourself.
81 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
83 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
84 before applying the handler in case it doesn't return.
86 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
88 * scmsigs.h, async.h: updated.
90 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
93 * posix.c (scm_uname): interpret only negative values as an error.
94 Solaris normally returns a positive value.
96 * script.c (scm_compile_shell_switches): if we are not going into
97 an interactive repl, set scm_mask_ints to zero so that asyncs can
100 * simpos.c (scm_system): don't ignore/unignore signals around
103 * posix.c (scm_open_pipe): don't ignore/unignore signals around
106 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
107 done in boot-9.scm instead.
109 * scmsigs.c, async.c: Major rewriting of signal handling code.
110 (scm_sigaction): new procedure.
111 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
113 (scm_raise): return unspecified, throw error on failure.
115 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
117 * regex-posix.c (scm_init_regex_posix): Register the "regex"
118 feature, to help boot-9.scm decide whether to import the regex
121 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
123 * eval.c: Include scmconfig.h at the beginning of the file so that
124 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
127 * regex-posix.c: #include "_scm.h" before conditionally #including
128 <regex.h>; the former defines HAVE_REGCOMP.
130 * regex-posix.c: #include <regex.h> conditionally, so the file is
131 CPP'able (for dependency scanning) even on systems that don't have
134 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
136 Add new R4RS-compliant syntax for keywords.
137 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
138 regardless of the setting of the `keywords' read option.
139 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
140 can be re-read no matter what the setting of the `keywords' read
143 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
145 Add support for POSIX regular expressions.
147 * regex-posix.c, regex-posix.h: New files. (Some code
148 is taken liberally from rx/rgx.c in the old Guile dist.)
150 * init.c: Include regex-posix.h.
151 (scm_boot_guile_1): Call scm_init_regex_posix.
153 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
154 Add regex-posix.[ch] sources.
155 * Makefile.in: Regenerated.
157 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
158 to do this automatically? It didn't for me, bleh.)
160 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
162 * fports.c (print_pipe_port): New function.
163 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
164 latter doesn't even take the right arguments.
166 * Makefile.am: Increment shared lib revision number. I think
167 sometimes the uninstalled Guile finds the installed shared lib;
168 Gord says doing this might help. As things turned out, I can't
170 * Makefile.in: Regenerated.
172 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
173 passing it as the closure argument to scm_boot_guile. (Bill
176 * ports.c (print_void_port, putc_void_port, puts_void_port,
177 write_void_port, flush_void_port, getc_void_port, close_void_port,
178 noop0): Use ANSI prototypes instead of K&R declarations, so the
179 initialization of void_port_ptob gets aggressively type-checked.
180 Fix arguments of print_void_port and write_void_port. (Bill

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

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

315 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
316 (scm_display_error_message): use RO macros when strings may be RO.
317 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
318 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
319 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

328 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
330 * error.c (scm_error): Add newline to error message.
332 * init.c (scm_init_standard_ports): Doc fix.
334 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
336 * dynl-shl.c: Completely replaced with new code from Bernard
339 * script.c (scm_ice_9_already_loaded): New variable.
340 (scm_compile_shell_switches): Use it.
342 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
344 * filesys.c (scm_input_waiting_p): add missing third argument to
347 * stime.c (scm_localtime): copy the result of localtime before
348 calling gmtime in case they share a buffer.
349 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
352 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
354 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
356 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
358 * Makefile.am (check-local): New target, which causes 'make check'
359 to run gh_test_c and gh_test_repl, with some trivial input.
360 * Makefile.in: Rgnrtd.
362 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
364 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
367 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
369 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
370 sure how this was supposed to work.
371 (scm_async_click): don't send SCM_TICK_SIGNAL.
372 (scm_init_async): don't initialize %tick-thunk.
374 * the following change doesn't affect the Scheme interface:
375 gc-thunk is called at the end of garbage collection. however it's
376 no longer implemented by pretending it's a signal.
378 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
379 system async corresponding to scm_gc_thunk.
380 * async.h: declare scm_gc_async.
381 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
382 gc-thunk directly, instead of going through a signal handler.
383 (scm_gc_async): new variable, points to the GC system-async.
384 (scm_init_async): save the GC async as scm_gc_async instead
385 of using system_signal_asyncs.
386 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
388 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
390 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
391 Don't screw up if we're interrupted.
392 * Makefile.in: Regeneradet.
394 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
396 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
398 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
399 we're not using AM_INIT_GUILE_MODULE any more.
400 * Makefile.in: Reneregated.
402 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
404 Functions for finding variable bindings, grace à Tim Pierce.
405 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
406 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
408 Get 'make dist' to work again.
409 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
410 * Makefile.in: Regenerated, like a surry without a fringe on top.
412 Changes for reduced Guile distribution: one configure script,
414 * configure.in, configure: Removed.
415 * acconfig.h, acinclude.m4: Moved to parent directory, where the
416 real configure script lives.
417 * Makefile.in, scmconfig.h.in: Regenerated.
419 * init.c: #include "script.h", to get prototype for script.c's
422 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
424 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
425 scm_must_malloc, not raw malloc.
427 * script.c (scm_compile_shell_switches): Dyke out debugging output
430 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
432 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
434 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
435 system has them. Hope this is safe. Previously
436 sys/timeb.h was included if HAVE_FTIME was defined or if
437 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
438 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
440 * ioext.c (scm_setfileno): add missing third argument to
443 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
445 * eq.c (scm_equal_p): Correctly compare strings of different
446 varieties. (Thanks to Tim Pierce.)
448 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
450 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
451 #! block comment must occur on a line all by itself.
453 Move most of the guts of shell command processing into libguile,
454 so guile.c can be very small (and eventuallly auto-generated. (I
455 mean, generated mechanically, not self-generated. Hmm.))
456 * guile.c, script.c, script.h: New source files.
457 * init.c (scm_boot_guile_1): Call scm_init_script.
458 * libguile.h: #include "script.h".
459 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
460 targets, for new executable.
461 (libguile_la_SOURCES): Mention script.c.
462 (modinclude_HEADERS): Add script.h.
463 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
464 not dynamic linking is enabled. This is because we're generating
465 executables now. Move CY_AC_WITH_THREADS call after those, so the
466 values of cy_cv_threads_libs captures the libs chosen above.
467 * Makefile.in, configure, aclocal.m4: Regenerated.
469 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
470 We don't maintain this interface any more, and it just confuses
473 * alloca.c: #include <scmconfig.h>, not <config.h>.
474 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
475 it'll get included in disties.
477 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>

506 coop-threads.c.cygnus, coop-threads.h.cygnus.
507 * configure.in: If we're using threads, include threads.o in
509 * _scm.h, libguile.h: threads.h lives in this directory now.
510 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
511 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
512 currently used, but brought along for information's sake.
513 * ChangeLog-threads: log from old 'threads' directory.
514 * Makefile.in, configure: Rebuilt.
516 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>

533 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
534 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
535 New variables, describing how to build the gh test programs.
536 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
537 build the test programs, and we probably should have been linking
538 libguile.la against them all along, to support AIX shared libs.
539 Add cflags for threads to CFLAGS; add libs for threads to new
540 variable THREAD_LIBS, used in Makefile.am.
541 * ChangeLog-gh: log from old `gh' subdirectory.
542 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
544 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
546 * acconfig.h: Undo change of Apr 9; including the definition of
547 PACKAGE in the guile headers conflicts with applications' own

560 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
562 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
563 have S_IFSOCK. This is the case under Ultrix.
565 * posix.c (scm_status_exit_val, scm_status_exit_val,
566 scm_status_term_sig, scm_status_stop_sig): Modified to work with
567 Ultrix versions of WIFSTOPPED, etc., which assume that their
568 arguments are lvalues (hmm).
570 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
574 * throw.c: Doc fixes; rearranged.
576 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.

580 * acconfig.h: Added entry for PACKAGE.
581 * scmconfig.h.in: Regenerated.

584 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
585 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
587 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
589 * Makefile.in: Rebuild.

598 (bdtime2c, setzone, restorezone): new static procedures.
599 (scm_mktime, scm_strftime): use them.
600 (scm_strftime): don't call mktime before strftime. Use
601 filltime for return value.
602 (filltime): convert NULL zname to #f.
603 (scm_strptime): return a count of characters consumed, not
604 the remaining string.
606 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
608 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.

615 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
617 * stime.c (scm_init_stime): don't define ticks/sec.
618 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
619 return value problem and is still portable.)
621 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
623 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
624 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
625 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
626 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
627 cpp_err_symbols.c): Corresponding changes.
628 * Makefile.in: Regenerated.
630 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
632 * posix.c (scm_putenv): don't check HAVE_PUTENV.
633 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
634 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
635 * putenv.c: new file, from sh-utils 1.12.
637 * posix.c (scm_environ): use malloc in place of scm_must_malloc
638 since allocation isn't for Scheme objects.
639 (scm_putenv): copy strings before placing in the environment.
641 * stime.c (scm_current_time): throw an error if time returns -1,
642 instead of returning #f.
643 (scm_get_internal_real_time, scm_get_internal_real_time): use
644 scm_long2num for return value instead of SCM_MAKINUM.
646 * stime.h: prototypes updated.
648 * stime.c (scm_time_in_msec): apparently unused, deleted.
650 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
652 * configure.in: check for gettimeofday.
654 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
655 which may be more usefully portable than a gettimeofday interface.
657 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
659 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
661 * Makefile.in: Regenerated.
663 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
665 * stime.c (filltime): recovered static procedure.
666 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from

670 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
672 * posix.c (scm_mknod): split the mode argument into type and perms
673 arguments, like the extra fields returned by stat.
675 * fports.c (scm_pipob): set the close, free and print procedures.
676 (scm_close_pipe): new procedure.
678 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,

681 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
683 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
684 wan't defined. Don't include fd.h.
686 * Previously fd.h was regenerated whenever configure was run,
687 forcing a couple of files to be recompiled.
689 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
690 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
691 Check for _fileno as well as _file.
693 * ioext.c: don't fd.h.
694 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
697 * Change the stratigy for getting information about errno
698 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
699 generating lists of symbols during the build process, which will
700 not always work, include comprehensive lists in the distribution.
701 To help keep the lists up to date, the "check_signals" and
702 "check_errnos" make targets can be used.
704 * configure.in: don't check for a command to extract errno codes.
705 * Makefile.am: update file lists, remove errnos.list and errnos.c
706 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
707 check_errnos targets.
708 (CLEANFILES): remove errnos.c and errnos.list, add
709 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
710 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
711 * errnos.default: deleted.
712 * cpp_signal.c: new file.
713 * cpp_errno.c: renamed from errnos_get.c.
714 * cpp_err_symbols, cpp_sig_symbols: new files.
715 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
716 * error.c (scm_init_error): #include cpp_err_symbols instead of
718 * posix.c (scm_init_posix): don't intern signal symbols. #include
721 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
723 * strop.c (scm_i_index): allow the lower bound to be equal to the
724 length of the string, so a null string doesn't always give an error.
726 * posix.h: new prototypes.
727 * posix.c (scm_status_exit_val, scm_status_term_sig,
728 scm_status_stop_sig): new functions, as in scsh. They break down
729 process status values as returned by waitpid.
731 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
733 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
734 configure doesn't know about it.
736 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
738 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
740 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
741 which defines C variables with global linkage.
743 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
745 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
748 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
750 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
751 has time to check why this doesn't work well with continuations.
753 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
755 * Fix shell syntax error; some shells won't tolerate
756 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
758 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
760 * posix.c (scm_uname): throw an error if uname fails instead
763 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
765 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
768 * async.c (scm_ints_disabled): definition moved from error.c.
770 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
772 * acconfig.h: Removed PACKAGE.
774 * scmconfig.h.in: Regenerated.
776 * snarf.h: g++ says it's non-portable not to specify the first
777 argument in a varargs declaration. I introduced the first
778 argument by using preprocessor conditionals.
780 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
782 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
783 (scm_freopen): use RO string macros for filename and modes.

787 (scm_mknod): use RO string macros for path.
789 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
790 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
792 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
793 use SCM_ROSTRINGP and SCM_ROCHARS.

797 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
800 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
801 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
802 support for byte vectors.
804 * print.c (scm_iprin1): Limit number of vector elements printed

812 * error.h: prototype for scm_error_scm.
814 * error.c (scm_error_scm): new procedure, reimplements scm-error
815 in C and uses scm_error.
817 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
819 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
820 pointer to the Scheme variable read-hash-procedures and intern it
821 in scm_init_read. Modify scm_read_hash_extend and
822 scm_get_hash_procedure to use the pointer.
824 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
826 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
827 (SCM_KEYWORD_STYLE): defined.
829 * read.c (scm_read_opts): add a keywords option. This isn't a
830 boolean option, in case someone wants to add support for DSSSL
832 Setup scm_keyword_prefix symbol.
833 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
835 I've left keyword support disabled by default, since it doesn't
836 seem to break the module system and it gives R4RS standard behaviour.
837 It can be reactivated with (read-set! keywords 'prefix).
839 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
841 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
842 before constructing arbiter.

845 closure before setting the procedure property!
847 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
849 * ports.c: Removed `ungetc-char-ready?'.

853 * read.c (scm_init_read): intitialise scm_read_hash_procedures
854 (idea from Mikael: make it a pair so scm_permanent object only
856 (scm_read_hash_extend): don't call scm_permanent_object.
857 (ideas from Mikael): if chr is already in the list, replace its
858 procedure instead of appending it again. If proc is #f, remove
860 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
862 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
864 * gdbint.c (gdb_read): update scm_lreadr usage.

869 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
871 * read.h: add prototype for scm_read_hash_extend. Change args for
874 * read.c (scm_read_hash_procedures): new variable.
875 (scm_read_hash_extend): new procedure.
876 (scm_get_hash_procedure): new procedure.
877 (scm_lreadr): use scm_get_hash_procedure instead of an argument
878 for extended # processing.
879 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
880 scm_read_token): remove case_i, sharp arguments. Change callers.
882 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
884 * read.h (SCM_N_READ_OPTIONS): increase to 3.
885 (SCM_CASE_INSENSITIVE_P): define.
887 * read.c: add case-insensitive option to scm_read_opts.
888 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
889 to determine whether to convert symbol case.
890 (default_case_i): definition removed.
891 * read.c (scm_read_token): if case_i, downcase ic before doing
894 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
896 * configure.in: Added configuration option `guile-debug'.
897 Configure with --enable-guile-debug if you want a bunch of extra
898 functions used for debugging when developing Guile.
900 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
902 * procs.c (make-cclo): New undocumented debugging procedure: Make
903 compiled closure with internal procedure PROC and length LENGTH.
904 Only compiled if GUILE_DEBUG is defined.
906 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
908 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
910 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.

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

937 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
938 from pairs with a GLOC in the car.
940 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
941 otherwise `symbol-hash' will behave badly.
942 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
943 we get segmentation fault!
945 * symbols.c: Added #include "weaks.h". New functions:
946 `builtin-bindings' and `builtin-weak-bindings'. (These will be
947 moved to an extraneous library when we split libguile.)
949 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
951 * filesys.c (scm_stat): stat now takes fport arguments too as
952 documented in the manual.
954 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
956 * debug.c (scm_single_step): Bugfix: Call continuation with
957 scm_call_continuation instead of throwing to it.
959 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
961 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
962 argument wasn't declared to be optional.
964 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
966 * stime.c (scm_init_stime): Add feature "current-time".
968 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
970 * throw.h: prototype for scm_exit_status.
971 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
972 args to derive an exit status. Allows (quit) to work from a
974 (scm_exit_status): new function.
977 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
979 * eval.c (scm_deval): Removed some old code.
980 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
982 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
985 * symbols.c (msymbolize): Bugfix: Must initialize property list to
988 * procs.c: Introduce the existent C function scm_thunk_p at the
989 Scheme level as well.
991 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
993 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
994 used from C to easily lookup the value of a symbol in the current
997 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
999 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
1000 scm_init_unif in this file. This will also fix a previous problem
1003 * configure.in: Added AM_MAINTAINER_MODE
1005 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1007 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
1010 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1012 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
1013 source files that are not always included in libguile but should
1014 have their dependencies calculated by automake. This variable is
1015 recognized by automake, no further magic is needed.
1016 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
1017 to deal exclusively with *.lo files, as it seems. The *.o files
1018 are built automatically when the corresponding *.lo file gets
1021 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
1023 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
1026 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
1028 * unif.c (scm_array_set_x): minor change to argument error checking.
1030 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
1032 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
1033 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
1034 They should only be included in the library at configure.in's
1036 (libguile_la_LDADD): Include the appropriate .lo files here.
1037 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
1038 so we know when to build them (and their .lo bretheren).
1039 * configure.in (LIBLOBJS): New substituted variable. We let
1040 configure decide which .o files to include in LIBOBJS, and then
1041 put the corresponding list of .lo files in LIBLOBJS. The latter
1042 is what we pass to libtool.
1043 * Makefile.in, configure: regenerated.
1045 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
1047 * symbols.c (scm_sysintern0): New function. Contains the core of
1048 old scm_sysintern but doesn't take a second value argument.
1049 (scm_sysintern): Now uses scm_sysintern0.
1050 (scm_sysintern_no_module_lookup): Renamed to
1051 scm_sysintern0_no_module_lookup and doesn't take a second value
1052 argument any longer.
1054 * symbols.h (scm_sysintern0: Added declaration.
1056 * options.c (scm_init_opts): Use scm_sysintern0 instead of
1057 scm_sysintern when interning option keys. Otherwise we risk
1058 destroying the values of already interned variables.
1060 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
1061 scheme-level boolean (use SCM_NFALSEP).
1063 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
1065 (scm_backtrace): New function. (C version of old function from
1066 boot-9.scm) Motivation: Make it possible to display backtraces
1067 without depending on boot-9.scm. (I'm uncertain if this
1068 motivation is good enough...)
1070 * root.h (scm_root_state): Add member the_last_stack_var.
1071 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
1073 * root.c (mark_root): Mark scm_the_last_stack_var.
1075 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
1078 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
1080 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
1081 1. mark_lazy_catch didn't mark the smob.
1082 2. Both functions above have standard variants:
1083 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
1084 free_lazy_catch --> scm_free0.
1086 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
1088 * throw.c (scm_internal_lazy_catch): New function.
1089 (scm_lazy_catch): Rewritten to use it.
1090 (scm_ithrow): Handle the new lazy catch representation.
1091 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
1092 that doesn't have a jmpbuf is a lazy catch clause.
1093 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
1094 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
1095 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
1097 (scm_init_throw): Register the new lazy-catch smob type.
1098 * throw.h (scm_internal_lazy_catch): decl for new function.
1100 * throw.c (scm_internal_catch): Doc fixes.
1102 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
1103 configure.in. Including this might cause problems if applications
1104 that link against libguile include their own copies of alloca, but
1105 if they're using autoconf, they should be adding libguile to LIBS
1106 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
1107 the copy in libguile, and things will be okay. (I think.)
1109 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1111 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
1113 strop.h: move prototypes too.
1115 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
1117 * posix.c (scm_init_posix): don't intern EINTR since it's now done
1120 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
1121 etc. I deleted them from filesys.c long ago, but didn't
1122 notice they were here too (although ineffective since
1123 sys/stat.h wasn't included).
1125 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
1127 * eval.c: Don't define alloca in GCC case. gcc will automatically
1128 use __builtin_alloca if appropriate.
1130 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1132 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
1133 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
1134 that values of automatic variables are preserved. See comments
1135 for safe_setjmp for details.
1137 Change from Thomas Morgan:
1138 * variable.c: Include eq.h.
1139 (var_equal): New function.
1140 (variable_smob): Use var_equal as the discriminator for variables.
1142 * throw.c (s_throw): Remove extraneous declaration.
1144 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
1145 * eval.c: Add necessary CPP cruft to support that.
1146 * configure, Makefile.in, scmconfig.h.in: regenerated.
1148 Change from Thomas Morgan:
1149 * procprop.c (scm_procedure_properties): Convert the Scheme
1150 boolean returned by scm_procedure_p into a C boolean before using
1151 it as a condition for SCM_ASSERT.
1152 (scm_procedure_property): Likewise.
1154 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
1155 indications of Unixness.
1158 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
1160 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
1162 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
1164 * read.c (scm_lreadr): use scm_misc_error to improve one of the
1165 "unknown # object" error messages.
1167 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
1168 (scm_i_index) and declare it static. Add a 'direction' argument
1169 to indicate what way the search should go.
1170 (scm_i_index): throw out-of-range error instead of wrong-type-arg
1172 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
1173 strop.h: remove scm_i_index, scm_i_rindex prototypes.
1175 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1177 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
1179 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
1180 to avoid clash with various scsh forks.
1182 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
1184 The following two changes (ramap.c, throw.c) are motivated by the
1185 apparent unportability of forward declarations of static arrays of
1186 the form `static foo bar[];'.
1188 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
1189 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
1191 * throw.c (scm_throw): Moved above scm_ithrow.
1193 * options.h: Removed the extern declarations of scm_yes_sym and
1194 scm_no_sym since these are static.
1196 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1198 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
1200 * Makefile.am: remove AWK=@AWK@.
1201 Add a rule for generating errnos.list.
1202 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
1204 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
1205 don't extract errnos, just set a variable (avoids the
1206 need to recompile error.c just because configure is run.)
1208 * unif.h: update prototypes.
1209 * unif.c (scm_uniform_array_read,write): change the offset and
1210 length arguments to start and end, for consistency.
1212 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
1214 * ioext.h: update prototypes.
1215 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
1216 scm_read_line_x, it's a more general procedure using an
1217 interface from scsh. read-line and read-line! are now defined
1219 Note that the new read-line trims the terminator
1220 by default, previously it was appended to the returned string. An
1221 optional argument specifies how to process the terminator (scsh
1222 compatible). For the old behaviour: (read-line port 'concat).
1223 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
1224 returns a pair, but is converted to multiple values if the scsh
1227 socket.h: update prototypes.
1228 * socket.c (scm_recvfrom): for consistency with other procedures,
1229 take start and end as separate optional arguments.
1230 (scm_recv, scm_recvfrom): don't allow the second argument
1231 to be a size, only a buffer. Change the scheme names to
1232 recv! and recvfrom!. Don't return the buffer.
1234 * ioext.h, posix.h: move prototypes too.
1235 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
1236 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
1237 "read.h" and "unif.h".
1238 * ioext.c: include "chars.h"
1240 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
1242 * dynl.c: The dynamic linking and module registration functions
1243 are now defined even when dynamic linking is not available for the
1244 host system. Some of their functionality can be done without
1245 dynamic linking; when it's really needed, they throw errors.
1247 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
1249 * configure.in: Only define DYNAMIC_LINKING when one of the system
1250 dependent functions is detected.
1251 * dynl.c (scm_dynamic_func): New function to get the address of a
1252 function in a dynamic object.
1253 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
1254 produced by scm_dynamic_func as the thing to call.
1256 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
1258 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
1259 (scm_register_module_xxx, scm_registered_modules,
1260 scm_clear_registered_modules): New functions.
1262 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
1264 * symbols.c (scm_sysintern): Renamed to
1265 scm_sysintern_no_module_lookup.
1266 (scm_sysintern): New function to take the place of the old
1267 scm_sysintern. It uses the current toplevel lookup closure to give
1268 the symbol its value. This is a temporary hack to put packages
1269 like gtcltk into their own module.
1270 (scm_can_use_top_level_lookup_closure_var): New variable to tell
1271 us whether `scm_top_level_lookup_closure_var' has been initialized
1273 * eval.c (scm_init_eval): Set it.
1275 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
1277 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
1278 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
1280 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
1282 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
1283 scm_sys_dup): deleted: FD capability will be added to other
1285 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
1286 scm_fd_free, fd_smob, scm_intern_fd.
1287 (scm_open): renamed from scm_sys_open. Return a port instead of
1288 an FD object. Make the mode argument optional.
1289 (scm_sys_create): deleted, it's just a special case of open.
1290 (scm_init_filesys): move interning of constants O_CREAT etc.,
1291 here (were previously using SCM_CONST_LONG macro).
1292 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
1294 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
1295 include "fports.h" and <stdio.h>
1296 (scm_stat, scm_select): don't support FD objects.
1298 * error.h: adjust scm_syserror_msg prototype.
1299 * error.c (scm_syserror_msg): take an extra argument for errno.
1300 Using the global value didn't always work, since it could be
1301 reset by procedure calls in the message or args arguments.
1303 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
1304 I don't understand why the check was there (and what about the
1307 * strop.c (scm_string_copy): allow shared substrings to be copied.
1309 * unif.h: corresponding change to prototypes.
1310 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
1311 recognize two new optional arguments: offset and length. Allow
1312 the port argument to be an integer (file descriptor, for scsh).
1313 Include <unistd.h> for "read" prototype.
1315 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
1317 * socket.c: don't include filesys.h.
1319 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
1321 * Makefile.am: add AWK=@AWK@ (?)
1323 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
1325 Add a rule to generate errnos.c from errnos.
1326 * error.c (scm_init_error): include errnos.c.
1327 * errnos_cnvt.awk: new file, converts the list of errno codes to
1329 * errnos_get.c: new file.
1330 * errnos.default: new file, contains errnos to try if they can't
1331 be extracted from errno.h.
1332 * configure.in: if using GCC, try and extract errno codes from
1336 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
1338 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
1339 * Makefile.am: Made libguile into a libtool library.
1340 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
1341 Set libtool_libs to indicate that libguile is a libtool library.
1342 See guile/ChangeLog for details.
1343 * .cvsignore: ignore "*.lo", the libtool library objects.
1345 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1347 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
1348 use htons in getservbyport argument.
1350 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
1352 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
1353 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
1356 * objprop.c (scm_object_property): No need to take the CDR of the
1357 value returned by scm_object_properties, since Aug 20 change.
1359 * configure.in: When checking for struct linger, #include
1360 <sys/types.h> as well as <sys/socket.h>. I've never known
1361 <sys/types.h> to cause any portability problems, and Solaris's
1362 <sys/socket.h> needs it.
1363 * configure: Rebuilt.
1365 I think the Sun compiler has chosen a perverse way to interpret
1366 ANSI declarations combined with K&R definitions. We'll
1367 appease it a little bit. But when it invades France, we fight.
1368 * print.c (scm_iprlist): Change 'tlr' argument to an int.
1369 * print.h (scm_iprlist): Here too.
1370 * numbers.c (scm_divbigdig): Change definition to match
1371 declaration in numbers.h.
1372 * unif.c (scm_makflo): Change definition to match declaration in
1375 * init.c (scm_boot_guile): Don't return the value of
1376 scm_boot_guile_1. This function doesn't return a value;
1377 scm_boot_guile_1 doesn't return a value (or return at all).
1379 * eval.c (unmemocopy): Add a semicolon to appease the Sun
1382 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
1383 compile. I have a feeling this function is a bad idea anyway ---
1384 one should always test for features, not systems.
1386 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
1387 semicolons. Only pure luck kept this from being noticed earlier.
1389 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
1391 * socket.c (scm_recvfrom): Added missing semicolon.
1393 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1395 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
1396 the buffer and start and end positions for scsh networking
1399 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
1401 * configure.in: Revert previous change to this file; the problem
1402 is due to transient automake weirdness.
1403 * configure: Rebuilt.
1405 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
1406 PLUGIN/guile.libs. configure generates the latter from the former.
1407 * Makefile.in: Rebuilt.
1409 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
1410 need this if we install scripts, like guile-snarf.
1411 * configure: Rebuilt.
1413 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1415 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
1417 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
1419 * socket.c (scm_addr_vector): fix faulty scm_listify.
1421 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
1423 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
1424 style block comment is no longer considered an error.
1426 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
1428 * PLUGIN/guile.libs.in: New file.
1429 * PLUGIN/guile.libs: Removed from repository.
1430 * configure.in: Create PLUGIN/guile.libs from
1431 PLUGIN/guile.libs.in. This is for including additonal libraries
1432 needed for dynamic linking.
1433 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
1434 instead of PLUGIN/guile.libs.
1436 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
1438 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
1440 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
1441 occurrences of the given element from the list, not just the
1442 first. This is how the Emacs Lisp functions behave, how the
1443 analogous Common Lisp functions behave, and (I believe) how the
1444 older Maclisp functions worked. I realize that this change may
1445 break code, but it seemed better to break it before the Guile
1448 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
1449 Their prototypes were already present in gc.h, but they weren't
1451 (scm_init_storage): Initialize scm_protects.
1452 * root.c (scm_protects): New element of scm_sys_protects.
1454 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
1456 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1458 * libguile.h: Added #include "libguile/net_db.h".
1460 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
1461 30 change. That file is only meant for communication between the
1462 configuration process and load.c. If code linked against libguile
1463 wants to get at the paths mentioned in libpath.h, it can call
1464 functions declared in load.h.
1466 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1468 * libguile.h: Removed #include "libguile/fdsocket.h"
1470 * net_db.c: Added #include <sys/socket.h>.
1472 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
1474 * filesys.c (scm_input_waiting_p): use select in preference to
1475 FIONREAD, since the latter doesn't detect EOF.
1476 Throw error if neither select nor FIONREAD available.
1478 * socket.c (scm_connect): take a port, not a fd object.
1479 (scm_fill_sockaddr): throw an error if fam is not recognised.
1480 (scm_bind): use scm_fill_sockaddr.
1481 (scm_listen): take a port, not a fd object.
1482 (scm_accept): take and return a port. return #f in the car if
1483 address can't be got
1484 (scm_sock_fd_to_port): new procedure.
1485 (scm_socket): use scm_sock_fd_to_port.
1486 (scm_addr_vector): throw error if unrecognised address type.
1487 take an extra argument with the calling procedure name.
1488 (scm_getsockname): take a port. return #f if address can't be got.
1489 (scm_getpeername): take a port. return #f if address can't be got.
1490 (scm_recvfrom): take a port. return #f for address component if can't
1492 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
1493 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
1495 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
1497 * throw.c (scm_internal_catch): Make body funcs and handler funcs
1498 use separate data pointers, to allow them to be designed
1499 independently and reused.
1500 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
1501 Renamed from catch_body, catch_handler, and uncaught_throw; made
1503 (struct scm_catch_body_data): Renamed from catch_body_data; moved
1505 (scm_catch): Use the above.
1506 (scm_throw): Don't bother printing a message for an uncaught
1507 throw; we establish a default handler in init.
1508 * throw.h (scm_internal_catch): Prototype updated.
1509 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
1511 (struct scm_body_thunk_data): New structure, used as data
1512 argument to scm_body_thunk.
1513 * init.c (struct main_func_closure): New structure, packaging up
1514 the data to pass to the user's main function.
1515 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
1516 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
1517 scm_internal_catch to establish a catch-all handler, using
1518 scm_handle_by_message. This replaces the special-case code in
1520 (invoke_main_func): Body function for scm_internal_catch; invoke
1521 the user's main function, using the main_func_closure pointer to
1522 decide what to pass it.
1523 * root.c (struct cwdr_body_data): Remove handler_proc member.
1524 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
1525 (cwdr_handler): Removed.
1527 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1529 * socket.h (SCM_P): update bind prototype.
1530 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
1531 include "feature.h".
1532 (scm_socket): return a port, not a file descriptor object.
1533 include "fports.h" and <unistd.h>
1534 (scm_bind): take a port, not a file descriptor object.
1535 take an extra argument for address args.
1537 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
1538 INADDR_NONE, INADDR_LOOPBACK.
1540 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1542 * init.c: include net_db.h and not fdsocket.h.
1543 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
1545 * Makefile.am: corresponding changes.
1546 * socket.h: renamed from fdsocket.h, fix names.
1547 * net_db.h: renamed from socket.h, fix names.
1548 * socket.c: renamed from fdsocket.c.
1549 remove _sys from procedure names.
1550 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
1551 add "socket" to features list.
1552 * net_db.c: renamed from socket.c.
1553 remove _sys from procedure names.
1554 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
1555 add "net-db" to features list.
1556 include "net_db.h". don't include <sys/socket.h> or
1559 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1561 * tags.h (scm_tags): Removed comma at end of last enumerator.
1563 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
1565 Don't use GCC extensions to allocate space for debugging frames.
1566 (Here he goes again! Why do we put up with this?!)
1567 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
1568 an scm_debug_info structure, not an in-line array of them. Add
1569 'info' member, to say how many vect elements we've used, for eval
1571 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
1572 a new variable debug_info_end to mark the end of vect, instead of
1573 the address of the 'info' pointer itself.
1574 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
1575 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
1576 (SCM_APPLY): Explicitly allocate space for debug.vect.
1577 * debug.c (scm_m_start_stack): Same, for vframe.vect.
1578 * stacks.c: Adjusted for new debug frame structure.
1579 (RELOC_INFO, RELOC_FRAME): New macros.
1580 (stack_depth, read_frames): Use them, and new scm_debug_frame
1581 element 'info', instead of magically knowing that eval frames have
1582 an info pointer sitting after vect.
1583 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
1585 (scm_init_stacks): Formatting tweaks.
1587 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
1589 Give GCC more control flow information, so it can be sure that
1590 variables aren't used uninitialized.
1591 * error.h (scm_error, scm_syserror, scm_syserror_msg,
1592 scm_sysmissing, scm_num_overflow, scm_out_of_range,
1593 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
1594 scm_misc_error): Tell GCC that these functions never return.
1595 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
1596 out the field type, call abort if SCM_ASSERT returns, to placate
1598 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
1599 scm_wta ever returns. We can't handle this case anyway, and this
1600 gives the optimizer more information.
1601 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
1602 scm_wta ever returns.
1604 In some cases, the code is fine, but GCC isn't smart enough to
1605 figure that out; this usually happens when one variable is only
1606 initialized and used when a particular condition holds true, and
1607 we know that condition will never change within a given invocation
1608 of the function. In this case, we simply initialize the variables
1609 to placate the compiler, hopefully to a value which will cause a
1610 crash if it is ever actually used.
1611 * print.c (scm_iprin1): Initialize mw_pos.
1612 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
1613 * throw.c (scm_ithrow): Initialize dynpair.
1614 * unif.c (scm_uniform_vector_ref): Initialize cra.
1615 * struct.c (init_struct): Initialize prot.
1616 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
1618 * strports.c (scm_eval_0str): Don't return uninitialized garbage
1619 if EXPR contains no expressions.
1621 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
1623 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
1624 cause an infinite loop (???). So much for the algebraic
1625 equivalency of variable-sized arrays and alloca...
1627 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
1629 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
1630 a SCM boolean, not a C boolean.
1632 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
1634 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
1635 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
1636 rules for raising scm_mtrigger. Previously, unfortunate but not
1637 unlikely circumstances could result in almost constant invokation
1638 of the gc. Now, this situations should be less likely, but they
1639 are not prevented completely.
1641 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
1643 * numbers.c (scm_fuck): Procedure removed; looks like old test
1645 * numbers.h: Prototype removed.
1647 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
1649 * debug.h (scm_debug_frame): Change `vect' member from an in-line
1650 array to a pointer, to match my Nov 21 change in eval.c.
1652 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1654 * libguile.h: Added #include "libguile/backtrace.h", #include
1655 "libguile/stacks.h".
1657 * strings.c (scm_string scm_make_string scm_string_ref
1658 scm_string_set_x scm_string_equal_p scm_string_append):
1659 Bugfix according to scm patch from Aubrey Jaffer:
1660 Corrected long-standing
1661 (not (eqv? (integer->char 128)
1662 (string-ref (make-string 1 (integer->char 128)) 0)))
1663 bug found by John Kozak <jk@noontide.demon.co.uk>.
1665 * strports.c, strports.h: Make scm_eval_0str return the value of
1666 the last expression evaluated (previously, it returned void).
1668 * strports.c, strports.h: New function: scm_read_0str. Does what
1671 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1673 * simpos.c (scm_getenv): return #f if string can't be found in the
1674 environment instead of throwing an exception, for compatibility
1675 with numerous other systems.
1677 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
1679 * Makefile.am (.c.x): Use guile-snarf.
1680 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1682 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1684 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1686 * backtrace.c (scm_display_error_message): Made non-static, and
1687 renamed from display_error_message.
1688 * backtrace.h (scm_display_error_message): Added extern decl.
1689 * throw.c (uncaught_throw): Use it to display the error message.
1691 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1693 * inet_aton.c: Use #if 0, not #ifdef 0.
1695 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1697 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1698 to convert the returned value.
1699 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1700 the offset argument.
1702 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1704 Add new interface to catch/throw, usable from C as well as
1706 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1707 (scm_internal_catch): New function, replaces...
1708 (scm_catch_apply): Deleted.
1709 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1710 mechanism which is a bit more code, but can be used nicely from C
1711 and implement the Scheme semantics as well.
1712 (scm_internal_catch): This is the replacement; it's named after
1713 the analogous function in Emacs.
1714 (scm_catch): Reimplemented in terms of the above.
1715 (struct catch_body_data, catch_body, catch_handler): New
1716 functions, used by scm_catch.
1717 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1718 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1719 support for new cwdr.
1721 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1724 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1726 * acconfig.h: Added DYNAMIC_LINKING symbol.
1727 * configure.in: Add option and checks for dynamic linking.
1728 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1729 dynl.h: New files for dynamic linking support.
1730 * Makefile.am (libguile_a_SOURCES):
1732 (modinclude_HEADERS): Added "dynl.h".
1733 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
1735 * init.c (scm_boot_guile_1): Call
1736 scm_init_dynamic_linking to initialize dynamic linking support.
1738 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
1740 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
1741 (as we Schemers say). It needs to be global, so that I can tweak
1742 it for the proper operation of unexec.
1743 (scm_boot_guile_1_live): New variable, see above.
1745 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
1747 * guile-snarf.sh: Removed.
1748 * PLUGIN/guile.libs: Added dependency for -lm.
1749 * acinclude.m4: Renamed from aclocal.m4.
1750 * PLUGIN/greet: Removed.
1751 * Makefile.am, aclocal.m4: New files.
1752 * configure.in: Updated for Automake.
1754 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
1756 * eval.c (scm_definedp): Use top_level_lookup_closure_var
1757 and not top_level_lookup_thunk_var.
1759 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
1761 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
1763 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
1765 * eval.c (scm_definedp): Incompatibly changed to be a builtin
1766 Scheme function, instead of syntax. Single argument is now a
1769 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1771 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1772 scm_ra_divide): Properly terminate statements passed as arguments
1773 to IVDEP macros. (Thanks to Bernard Urban.)
1775 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1776 with non-constant sizes. (Thanks to Bernard Urban.)
1778 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1780 It's an "eval closure", not an "eval thunk." A thunk is a
1781 function of no arguments.
1782 * root.h (struct scm_root_state): Renamed
1783 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1784 (scm_top_level_lookup_closure_var): Renamed from
1785 scm_top_level_lookup_thunk_var.
1786 * root.c (mark_root): Uses changed.
1787 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1788 * init.c (scm_start_stack): Uses changed.
1789 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1790 Change scheme-visible name to *top-level-lookup-closure* from
1791 *top-level-lookup-thunk*.
1793 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1795 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1796 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1798 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1800 * gc.c (struct scm_heap_seg_data): Doc fixes.
1802 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1803 sweeping. Then, prepend each segment's free cells to its
1804 freelist, rather than wiping out the old value. (Thanks to Marius
1807 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1808 scm_check_freelist, scm_debug_newcell): New functions and
1809 variables, for debugging freelist problems.
1810 * pairs.h (SCM_NEWCELL): New debugging version added.
1811 * gc.h (scm_debug_newcell): Added extern declaration, used by
1812 debugging version of SCM_NEWCELL.
1814 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1816 On some systems <libc.h> conflicts with <unistd.h>, and should not
1817 be #included at all.
1818 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1819 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1820 * configure.in: Call it.
1821 * posix.c, filesys.c: Use its results to decide whether or not to
1823 * configure, scmconfig.h.in: Rebuilt with autoconf and
1826 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1828 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1829 pointer to the stdio stream before calling scm_setbuf0, so the
1830 latter will be able to retrieve it. I'm surprised this didn't
1831 segfault earlier. (Thanks to Christopher Lee.)
1833 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1835 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1838 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1840 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1841 number of stack narrowing specifier pairs. The first specifier in
1842 a pair controls inner border, the second the outer border. A
1843 number means cut that number of frames, a procedure object means
1844 cut until that object is found in operator position in a frame.
1846 * root.c (cwdr): Bugfix.
1848 * read.c: Recording of positions disabled by default.
1850 * procs.c (scm_closure_p): New function.
1852 * posix.c (scm_tmpnam): New function.
1854 * load.c: Added #include "throw.h".
1855 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1858 * load.c, load.h (scm_read_and_eval_x): New function.
1860 * eval.c: Renamed debug option "deval" to "debug".
1862 (scm_eval_x): `eval!' is no longer accessible from the scheme
1863 level. Motivation: We can't allow operations which introduce
1864 glocs into the scheme level. Guile's type system can't handle
1865 these as data. Use `eval' or `read-and-eval!' as replacement.
1867 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1868 SCM_CONSP since this is a macro!; Set vframe.prev to
1869 scm_last_debug_frame instead of 0. In this way we can look
1870 "above" the virtual start stack frame if we wish.
1871 (scm_debug_hang): New function: Useful for debugging Guile in
1872 certain tricky situations. Will probably be removed later...
1874 * debug.h: Changed semantics of debug option "backtrace". This
1875 option now only indicates whether we want automatic backtrace at
1878 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1880 * ports.c: #include "filesys.h"
1881 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1883 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1884 Motivation: This is system specific code which is related to file
1885 I/O. It also may use select. Added code by Gary Houston to
1886 detect presence of character in stdio buffers.
1888 * libguile.h: #include "libguile/libpath.h"
1890 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1891 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1892 SCM_SITE_DIR; Install libpath.h among the other include files.
1894 * load.c, load.h (scm_sys_package_data_dir): New function.
1896 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1898 * stacks.h: Bugfix: Don't use tail-array length field as stack
1899 length field! This screwed GC.
1901 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1903 * _scm.h: Added #ifndef around definition of macros min and max.
1905 * __scm.h: Added hooks for threads to plugin to in ints protection
1906 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1907 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1908 the main code in these macros duplicated and spread over multiple
1909 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1910 SCM_THREAD_SWITCHING_CODE.
1912 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1914 * snarf.h: New file.
1915 * guile-snarf.sh: New file.
1916 * Makefile.in (inner_h_files): Added snarf.h
1917 (ancillary, install, uninstall, distclean): Added actions for
1919 (.c.x): Use guile-snarf.
1920 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1921 (gen_c_files): Note that these depend on guile-snarf.
1922 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1923 now in "snarf.h". Added #include "snarf.h" to get them.
1924 * libguile.h: Added #include "snarf.h".
1925 (Patches applied and tweaked by Jim Blandy.)
1927 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1929 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1930 standards suggest against providing prototypes for system
1931 functions. Thanks to Greg Troxel.
1933 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1935 * strports.c (scm_eval_0str): New function.
1936 #include "read.h", to get prototype for scm_read.
1937 * Makefile.in (strports.o): Update dependencies.
1938 * strports.h: New prototype.
1940 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1941 scheme name from "int?" to "integer?". It seems to do the job.
1942 * numbers.h: Rename prototype too.
1943 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1946 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1947 scm_num_eq_p): Rename these according to R4RS conventions: call
1948 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1949 to making libguile R4RS compliant without ice-9...
1951 * load.c (scm_sys_search_load_path): Search for files under all
1952 extensions listed in the %load-extensions variable. If FILENAME
1953 is absolute, return it unchanged, without searching the load path.
1954 (scm_loc_load_extensions): New variable, pointing to
1955 %load-extensions' value cell.
1956 (scm_init_load): Initialize it, and the value it points to.
1957 (scm_primitive_load_path): Improve error reporting.
1959 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1960 of new Scheme variable %load-hook.
1961 (scm_primitive_load): Apply %load-hook to filename.
1963 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1965 * configure.in: add tests for figuring out whether buffered data
1966 is available in a FILE structure, which is needed by char-ready.
1968 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1971 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1972 exceptions using misc_error instead of syserror. It seems a bit
1973 odd to throw an exception if a string can't be found in the
1974 environment, but it's consistent with open-file, stat etc.
1975 (simpos.h): remove sys_ from getenv.
1977 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1978 occurs, throw an error instead of returning errno. Return value
1980 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1982 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1984 * filesys.c (scm_stat2scm): derive file type and permissions from
1985 the stat mode and append them to the returned vector.
1986 There isn't much overhead in doing this and it avoids the need to
1987 work with S_IRUSR et al. in Scheme.
1988 Define symbols scm_sym_regular etc.
1989 (scm_init_filesys): don't intern S_IRUSR etc.
1991 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1992 and s_primitive_load_path.
1994 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1996 * error.h: don't declare error symbols. prototype for scm_misc_error.
1998 * stackchk.c (scm_stack_overflow_key): defined here instead of in
2001 * error.c: use SCM_SYMBOL to set up error keys.
2002 scm_misc_error: new procedure.
2004 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2006 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
2007 between `#!' and `!#' is ignored.
2008 (skip_scsh_block_comment): New function.
2010 * feature.c (scm_set_program_arguments): New argument, FIRST.
2011 * feature.h: Update prototype.
2012 * init.c (scm_boot_guile_1): Pass new argument to
2013 scm_set_program_arguments.
2015 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
2017 * init.c (scm_start_stack): Don't initialize scm_progargs here.
2018 (scm_boot_guile): Call scm_set_program_arguments here, later than
2019 the old initialization.
2021 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
2022 initialization procedure.
2023 - Delete in, out, err arguments; there are other perfectly good
2024 ways to override these when desired.
2025 - Delete result argument; this function shouldn't ever return.
2026 - Rename init_func argument to main_func, for less confusion.
2027 - Delete boot_cmd argument; main_func is more general.
2028 -Add 'closure' argument, to help people pass data to main_func
2029 without resorting to global variables.
2030 - Abort if reentered; don't bother returning an error code.
2031 - Call scm_init_standard_ports to set up the default/current
2032 standard ports; no need to pass them to scm_start_stack.
2033 - Remove code to evaluate the boot_cmd, and start the repl; let
2034 the user do something like that in main_func if they want.
2035 - Remove code to package up a return value; main_func can do any
2037 - Call exit (0), instead of returning.
2038 (scm_start_stack): Don't initialize the I/O ports here; that's
2039 weird. Delete in, out, err arguments. Move guts to
2040 scm_init_standard_ports, scm_stdio_to_port.
2041 (scm_init_standard_ports): New function, to set up current and
2042 default standard ports.
2043 (scm_start_stack, scm_restart_stack): Make these static.
2044 * init.h (scm_boot_guile): Adjust declaration.
2045 (scm_start_stack, scm_restart_stack): Remove externally
2046 visible declarations for these.
2047 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
2049 * fports.c (scm_stdio_to_port): New function. Its guts used to be
2050 written out several times in scm_start_stack.
2051 * fports.h: New declaration for the above.
2053 * feature.c (scm_set_program_arguments): New function.
2054 * feature.h: New declaration for the above.
2056 * ports.c: Formatting tweak.
2058 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
2060 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
2061 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
2062 for obtaining the address of a car or cdr field. Motivation:
2063 &SCM_CXR make assumptions about the internal structure of the
2066 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
2067 Motivation: see SCM_CXRLOC.
2069 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
2070 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
2071 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
2072 Motivation: Safer use. Some other macros are defined in terms of
2073 these operations. If these are defined using the SCM_SETCXR
2074 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
2075 to inefficiency and an <e1> with side-effects could potentially
2076 break. Also, these particular operations are heavily utilized in
2077 the garbage collector. In unoptimized code there will be a
2080 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
2081 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
2082 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
2083 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
2084 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
2085 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
2086 vports.c: Cleaned up use of pairs: Don't make any special
2087 assumptions about the internal structure of selectors and
2088 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
2089 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
2090 (Among other things, this change makes it easier to build Guile
2091 with certain compilers which have problems with casted lvalues.)
2093 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2095 * stacks.c: Improve selection of relevant stack frames when making
2096 a stack object. Introduce one level of indirection in the stack
2097 object to make it possible to "narrow" to a certain region of the
2098 stack. This facilitates making use of more clever algorithms (not
2099 implemented) for selecting relevant frames and gives a cleaner
2100 design since selection of frames can be done independently of
2101 extraction of frames from the real stack.
2102 (scm_stack_id): Also take #t as argument which means look at
2105 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
2106 Turn n_tail into an integer directly representing current number
2107 of frames in stack. Add field tail.
2109 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
2111 * debug.c (scm_make_memoized): Made it available at scheme level.
2112 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
2113 SCM_NIMP before applying heavier predicates in argument checking.
2114 (scm_local_eval): Also take memoized object as argument.
2116 * backtrace.c (scm_display_error): Just a safety measure: Stacks
2117 aren't created with zero length, but should such a strange
2118 creature suddenly turn up...
2120 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
2122 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
2123 `del', for the sake of C++ compilers. (Patch applied by JimB.)
2125 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
2127 * variable.c (scm_make_variable): Make the name hint optional, as
2129 (anonymous_variable_sym): Renamed from variable_sym. All uses
2132 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
2133 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
2134 of scm_primitive_load_path was also changed to
2135 "primitive-load-path", from "%try-load-path". Callers changed.
2136 We'd like to respect the convention that a function named
2137 "try-mumble" should behave just like the function called "mumble",
2138 but return #f instead of signalling some error.
2139 * load.h: Rename prototypes.
2141 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2143 * print.c (make_print_state, grow_print_state), print.h: Modified
2144 the print state representation: Don't use a tail array for
2145 recording of circular references. Resizing of the print state
2146 structure invalidates the print state pointer. To avoid passing
2147 around an indirect print state reference to all printing
2148 functions, we instead let the print state reference a resizable
2151 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2153 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
2154 Don't crash when passed an improper list terminated by a
2155 non-immediate value.
2157 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
2159 Allocate data for structures on an eight-byte boundary, as
2160 required by the tagging system.
2161 * struct.c (alloc_struct): New function.
2162 (scm_make_struct, scm_make_vtable_vtable): Call it.
2163 * struct.h (scm_struct_n_extra_words): Bump to 3.
2164 (scm_struct_i_ptr): New "field".
2165 * gc.c (scm_gc_sweep): When we need to free the data, use the
2166 information stored by alloc_struct to find the beginning of the
2167 block allocated to the structure, so we can free it.
2169 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2171 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
2174 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
2175 (scm_debug_info): New member: id.
2177 * stacks.c: Stacks are now represented as structs; Stacks have an
2178 id given to them by `start-stack'.
2179 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
2181 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
2182 Changed stack representation.
2184 * debug.c (scm_procedure_name): Try procedure property `name' for
2185 compiled closures aswell.
2187 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
2189 * eval.c: scm_i_name moved to gsubr.c
2190 (scm_m_define): Record names of all kinds of procedure
2191 objects. (Earlier, only closures were recorded.)
2193 * procprop.h: Added declaration of scm_i_name.
2195 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
2196 (scm_make_gsubr): Record names of compiled closures.
2198 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2200 * debug.c, debug.h: Removed obsolete code.
2202 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
2203 stacks.c: Renamed regs --> scm_contregs.
2205 * print.c (scm_free_print_state): Cleanup print state before
2206 returning it to pool. It is better to do it here than in
2207 scm_prin1 since scm_prin1 is called often.
2209 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
2210 s_set_source_property_x): Check that first argument is a pair or a
2213 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
2214 scm_i_line, scm_i_column and scm_i_breakpoint global.
2216 * init.c: Added #include "backtrace.h" and #include "stacks.h".
2217 (scm_boot_guile_1): Added calls to scm_init_backtrace and
2220 * debug.h: Added debug object smob declaration and macro
2223 * configure.in: Build with backtrace.o and stacks.o if debug
2226 * Makefile.in: Added entries for new files: backtrace.c,
2227 backtrace.h, stacks.c and stacks.h.
2229 * symbols.c (scm_sym2ovcell): Fixed documentation.
2231 * _scm.h (min, max): Added.
2233 * async.c: Moved `min' macro to _scm.h.
2235 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
2236 SCM_BACKTRACE_INDENT.
2238 * eval.c: Added new debug options `maxdepth' and `indent'.
2240 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
2242 * print.h: Added selector SCM_PRINT_STATE.
2244 * print.c: New functions: scm_make_print_state,
2245 scm_free_print_state.
2247 * print.h: Added declarations for scm_make_print_state,
2248 scm_free_print_state.
2250 * debug.c (scm_m_start_stack): New acro.
2252 * debug.h: Small cleanup.
2254 * init.c (scm_boot_guile_1): Moved scm_init_debug below
2257 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

2277 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
2278 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
2279 declare functions with prototypes. (Patch thanks to Marius
2282 More prototype-related changes from Marius Vollmer:
2283 * gdb_interface.h: Wrapped header file in #ifdef/#endif
2284 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
2285 * ports.h (ptobfuns): Added prototypes. This means some casting in
2287 * fports.c: Added casts for initializations, since the functions
2288 are defined to take FILE * as their stream argument, not SCM.
2289 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
2290 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
2291 to `char *str_data' to conform to prototype.
2293 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2295 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
2297 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
2299 * stime.c, stime.h: use SCM_P method.
2301 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2303 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
2304 be given at least two arguments. Insist that lst's last element
2305 be a list, but don't make any requirements of its predecessors.
2307 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2309 * eval.c (scm_nconc2last): Revert last change; there seems to be
2310 other stuff going on here.
2312 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2314 * eval.c (scm_nconc2last): Make sure that each element of lst
2315 (which is a list of argument lists, except for the tail) is a
2316 proper list, i.e., finite and terminated by '().
2318 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2320 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
2323 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
2324 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
2327 * vectors.c (scm_make_vector): Fill vectors with the undefined
2328 value, to help make Guile Scheme code more portable to other
2331 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
2332 * symbols.h, tags.h: Doc fixes.
2334 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
2336 * async.c (scm_take_signal): Doc fixes.
2338 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
2340 * numbers.c (scm_divbigint): When the remainder is zero, we don't
2341 want to subtract it from the modulus; we just want to leave it
2344 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
2346 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
2349 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
2351 * throw.c (scm_catch_apply): Finished implementation of
2354 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2356 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
2358 (scm_init_filesys): set "i/o-extensions" feature.
2361 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
2363 * Makefile.in (root.o): Correct dependencies.
2365 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
2367 * Makefile.in: Added dependency entry for root.o.
2369 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
2370 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
2372 * init.c (scm_start_stack): Set initial root continuation number
2375 * procs.c: New function: scm_thunk_p.
2377 * procs.h: Added declarations of scm_thunk_p.
2379 * root.c: Renamed `call-with-new-root' -->
2380 `call-with-dynamic-root'.
2381 (cwdr): Removed allocation of new root state. This should be done
2382 separately by use of scm_make_root.
2383 (scm_apply_with_dynamic_root): New function: Does what it
2384 sounds like. Needed when spawning threads.
2386 * root.h: Added member last_debug_frame to root state.
2387 Added #include "libguile/debug.h"
2389 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
2390 arguments. The motivation is that code in root.c needs catch
2391 functionality, and we want to avoid code duplication.
2392 New functions: scm_catch, scm_lazy_catch. These are wrappers for
2393 scm_catch_apply. scm_lazy_catch is intended to introduce catch
2394 handlers that run without popping the stack into the dynwind
2397 * throw.h: Added prototypes for scm_catch_apply and
2400 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2402 * root.h (scm_root, scm_set_root): Decouple thread support details
2403 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
2404 SCM_SET_THREAD_LOCAL_DATA.
2406 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
2407 and tortoise scanning loop.
2409 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
2411 * Makefile.in: Rebuild dependencies.
2413 * libguile.h: #include "libguile/print.h" before "smob.h", since
2414 the latter uses the print_state structure.
2416 * throw.c (scm_ithrow): Use the correct variable when checking to
2417 see if a given element of scm_dynwinds is a valid catch.
2419 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
2420 structure, abort; don't just silently ignore the garbage.
2422 * _scm.h: #include "print.h" here, since it seems to be used just
2424 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
2425 strports.c, unif.h: Don't #include "print.h".
2427 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2429 * feature.h (scm_loc_features): Removed external declaration.
2430 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
2432 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2434 * feature.c (scm_init_feature): Added threads feature (needs to be
2435 initialized here, since features doesn't exist when
2436 scm_init_threads is called).
2438 * libguile.h: Added #include "libguile/../threads/threads.h".
2439 (This is a kludge to get thread support working. This should be
2442 * configure.in, acconfig.h: Added flags for thread support.
2444 * scmsigs.c: Define `signal' to be `pthread_signal' if using
2447 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
2448 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
2451 * _scm.h: Added conditional #include "threads.h"
2453 * __scm.h (SCM_ASYNC_TICK): Added call to macro
2454 SCM_THREADS_SWITCHING_CODE.
2456 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
2457 allocate the basic dynamic root object.
2458 (scm_boot_guile): Added call to scm_init_root.
2460 * root.c, root.h: Added root smob.
2461 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
2462 functions: Implements dynamic roots mostly according to spec in
2463 SCM manual. Main difference is that the second argument is a
2464 throw handler rather than an error "thunk".
2466 * root.h: Added declaration of scm_init_root.
2468 * root.c: Added #include "genio.h", #include "smob.h", #include
2469 "pairs.h", #include "throw.h", #include "dynwind.h", #include
2471 (scm_init_root): Added #include "root.x".
2473 * throw.c: Added #include "stackchk.h"
2474 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
2475 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
2476 can be used in scm_call_with_new_root; Added reenabling of stack
2477 checking when catching a throw.
2479 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
2481 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
2483 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
2484 element is not found, as per R4RS.
2486 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2488 * list.c: Doc fixes throughout.
2490 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2492 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
2493 declare the char * to be const. Avoids a warning in rgx.c.
2495 * ports.h: spelling fix.
2497 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
2500 * load.c (scm_sys_try_load_path): throw an error if file not found
2501 (like it says it in NEWS).
2503 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2505 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
2506 PROPS slot to '(), not #f; it's an empty alist.
2508 * throw.h, throw.c: Use SCM_P instead of #if hair.
2510 Remove special support for uncaught throws; see throw.c for
2512 * throw.c (uncaught_throw): New function.
2513 (scm_ithrow): Call uncaught_throw if we don't find a throw
2514 target; don't mess with scm_bad_throw_vcell.
2515 (scm_bad_throw_vcell): Variable deleted.
2516 (scm_init_throw): Don't initialize it.
2518 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
2521 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2523 * numbers.c (scm_istr2int): If the number is short (as most
2524 numbers are), just call scm_small_istr2int to deal with it.
2525 (scm_small_istr2int): New function, created by un-#ifdefing the
2526 non-bignum version of scm_istr2int and renaming it.
2528 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
2530 * load.c (scm_sys_try_load): don't check whether value returned
2531 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
2532 Change the Scheme name from %try-load to primitive-load.
2534 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
2535 Can avoid passing a message, allowing it to be derived in the
2536 error handler (e.g., if we want to throw to the key both from
2539 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
2541 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
2542 references now have a new appearance which is more compact and
2543 also gives a clue about what the target of the reference is.
2544 By setting parameters in the print state, more fancy printing can
2545 be achieved. This is used by the (not yet commited) backtrace
2548 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
2550 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
2553 * print.c: Added #include "struct.h". Removed function
2556 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
2557 scm_iprin1. Removed prototype for scm_prlist.
2559 * arbiters.c (prinarb),
2560 async.c (print_async),
2561 debug.c (prindebugobj, prinmemoized),
2562 eval.c (prinprom, prinmacro),
2563 filesys.c (scm_fd_print, scm_dir_print),
2565 mallocs.c (prinmalloc),
2566 numbers.c, numbers.h (scm_floprint, scm_bigprint),
2567 smob.h (scm_smobfuns),
2568 srcprop.c (prinsrcprops),
2570 unif.c, unif.h (scm_raprin1, rapr1),
2571 variable.c (prin_var): Changed argument `int writing' to
2572 `scm_print_state *pstate'.
2574 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
2575 that it will be called before scm_init_print.
2577 * print.c (scm_prin1): Print states are now allocated when calling
2578 scm_prin1 and then passed around to all printing functions as an
2579 argument. A cache `print_state_pool' enables reuse of print
2581 (scm_make_print_state): New function.
2582 (scm_iprin1): Adaption to print states.
2583 (scm_iprlist): An initial "hare and tortoise" scan brings down
2584 time complexity to O (depth * N). (Better time complexity will be
2585 achieved when the printing code is completely rewritten.)
2587 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2589 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
2590 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
2591 it gets done whether or not the cache variable has a value.
2593 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2595 Distinguish #f and ().
2596 * __scm.h: #undef SICP.
2597 * pairs.h (SCM_EOL): Delete this definition, equating it with
2599 * tags.h (SCM_EOL): Give it a new definition here; I think I found
2600 the value it used to have. Doc fixes, too.
2602 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
2604 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
2605 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
2606 Lord's implementation of structs, allowing for tail arrays as
2607 described in the manual. Also fixed some bugs. (Both the interface
2608 and the implementation should be improved.)
2610 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
2612 * print.c, print.h: Closures now print like #<procedure foo (x)>.
2613 People who whish to see the source can do `(print-enable 'source)'.
2614 Removed #ifdef DEBUG_EXTENSIONS.
2616 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2618 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
2619 integer (assuming for now accepting an integer is a good thing).
2621 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2622 %S will be used instead for write'ing arguments.
2624 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2625 asserts. fix a few other asserts.
2626 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2627 scm_uniform_vector_ref, scm_array_set_x,
2628 scm_dimensions_to_unform_array): change args in
2629 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2630 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2631 scm_substring_fill_x): likewise.
2632 gsubr.c (scm_gsubr_apply): likewise.
2633 eval.c (SCM_APPLY): likewise.
2635 * eval.c (4 places): replace scm_everr with lgh_error or
2638 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2639 scm_memory_error): new procedures.
2640 scm_everr: deleted. can use scm_wta, dropping first two args.
2641 scm_error: convert NULL subr to SCM_BOOL_F.
2643 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2646 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2649 * error.c, error.h: new error keys: scm_arg_type_key,
2650 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2652 scm_wta: reimplement using lgh_error instead of scm_everr.
2654 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2656 * gdbint.c: scm_lread now has one more argument.
2658 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2659 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2660 loading source from non-file ports, which, e. g., happens when
2661 using the Emacs interface).
2663 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2666 * read.c: Added code for recording of positions of source code
2667 expressions; New functions: recsexpr, scm_lreadrecparen;
2668 _scm_make_srcprops --> scm_make_srcprops
2669 (scm_flush_ws): Removed updating of positions counters. This work
2670 is already done by scm_gen_getc
2672 * read.h: Added prototype for scm_lreadrecparen
2674 * print.c: Added #include "alist.h"
2676 * eval.c: Added #include "hash.h"
2678 * eq.c: Added #include "ramap.h"
2680 * options.c: Documentation fixes.
2682 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
2683 (scm_init_srcprop): Adjusted size of initial source-whash. Name
2684 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2685 --> scm_make_srcprops
2687 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2688 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2689 function calls in the definition of the whash access macros.
2691 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2693 * init.c (scm_boot_guile): Add level of indirection to
2694 scm_boot_guile_1() to ensure that stack base pointer is properly
2695 initialized. There was no guarantee that variable i was the
2696 highest/lowest variable on stack (i.e. the call frame of
2697 scm_boot_guile was not completely protected from gc).
2699 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2701 * ports.h (scm_port_table): put back file_name, it will be used to
2702 support debugging. Undo related changes in fports.c, ioext.c,
2705 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2707 * ports.h (scm_port_table): remove file_name member for now, it seems
2709 * fports.c (scm_open_file): don't set file_name in PTAB.
2710 (prinfport): don't use file_name in PTAB.
2711 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2712 * ports.c (scm_add_to_port_table): don't intialize file_name.
2713 (scm_port_file_name): remove for now.
2714 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2716 * fports.h (scm_mkfile): prototype deleted.
2717 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2719 * debug.c, unif.c: use scm_out_of_range instead of
2720 wta for range errors (ASSERT still needs work).
2722 * error.c, error.h (scm_out_of_range): new procedure.
2724 * error.c, error.h (scm_out_of_range_key): new key.
2726 * posix.c (scm_sync): #else was missing.
2728 * error.c, error.h: append _key to names scm_num_overflow and
2731 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2732 of consing an empty list.
2733 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2734 of macros, saves code and string space.
2735 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2736 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2737 lower case. Rename scm_syserror_m to scm_syserror_msg.
2738 error.h: prototypes for new procedures.
2740 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2742 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2744 * error.c, error.h: setup scm_num_overflow key.
2746 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2747 Remove definition of SCM_OVSCM_FLOW.
2749 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2751 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2752 explicit message and args.
2754 * error.c, error.h, __scm.h: change system_error_sym to
2757 * error.c (system_error_sym): remove leading %% from the Scheme name
2760 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2762 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2764 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2765 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2766 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2767 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2768 renamed. (These were introduced by unsupervised name
2771 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2773 * print.c: Added code for detection of circular references during
2774 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2775 a hook for printing of closures (accessible via print options).
2776 This leads to a split of calls to scm_iprin1 into two classes:
2777 elementary print operations (e. g. the code which prints a smob)
2778 still use scm_iprin1 while top level calls (like scm_display) use
2779 scm_prin1. scm_prin1 begins by clearing the data structure used
2780 to record reference information.
2782 * print.h: Added declarations of scm_prin1 and scm_prlist.
2784 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2786 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2788 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2790 * error.c (err_head): scm_iprin1 --> scm_prin1
2792 * debug.c: Adjusted header comment.
2796 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2798 * strerror.c: Doc fix.
2800 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2802 * gdbint.c (gdb_read): Now possible to run during GC.
2803 (unmark_port, remark_port): New functions.
2805 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2807 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2808 of allocating a new string object. Also, increase size by
2809 the factor 2 instead of 1.5.
2811 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2813 * __scm.h (SCM_P): Corrected to run under traditional C.
2815 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2818 * async.c: Calls to scm_sysintern corrected.
2820 * async.h (scm_async_clock): Redundant declaration removed.
2822 * continuations.c (scm_dynthrow): Redundant declaration removed.
2824 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2825 Definition typos corrected.
2827 * debug.h: Missing declarations of functions in debug.c added
2830 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2831 Missing declarations to functions in eval.c added.
2833 * filesys.c: Possibly uninitialized variable rv.
2835 * gc.h (scm_object_addr, scm_unhash_name): Missing
2836 declarations of functions defined in gc.c added.
2838 * genio.c: Possible typos str_data -> wstr_data. ???
2840 * genio.c: Possibly unintended shadowing of local variable
2841 `int c' (gotos out of scope of inner `c'). ???
2843 * init.c: Uninitialized `SCM last' may be used.
2845 * ioext.h: (scm_sys_isatty_p): Typo.
2847 * list.h (scm_list_head): Missing prototype for function in
2850 * numbers.c (scm_two_doubles): Changed from extern to static
2851 (is used only within numbers.c).
2853 * numbers.h: Repeated declarations removed.
2855 * ports.h (scm_close_all_ports_except): Declaration for the
2856 function defined in ports.c added.
2858 * posix.h: Missing declarations added.
2860 * procs.h (scm_make_subr_opt): Missing declaration added.
2862 * socket.h (scm_sys_gethost): Missing declaration added.
2864 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2866 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2867 Missing declarations added.
2869 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2871 * struct.c: Uninitialized variable `SCM answer' may be used.
2873 * unif.c (l2ra): Declaration prototype.
2875 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2876 defined in ramap.c).
2878 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2879 Redundant declarations removed (they are in ramap.h).
2881 * variable.h (scm_make_udvariable,
2882 scm_make_undefined_variable): Declaration corrected to
2883 correspond variable.c.
2885 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2886 Missing declarations added.
2888 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2890 * Makefile.in (distclean): Don't forget to delete fd.h.
2892 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2894 * fd.h.in, tags.h: Trivial cleanups.
2896 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2897 marksweep.h just declared functions from gc.c.
2898 * gc.h, libguile.h: Don't #include "marksweep.h".
2899 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2900 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2901 dependencies updated.
2903 * libguile.h: Don't #include "files.h"; it's been deleted.
2905 * files.c (scm_sys_delete_file): Moved to filesys.c.
2906 File is now empty; deleted.
2908 * filesys.c: scm_sys_delete_file is now here. Remove
2909 #if's; they seem to rely on remnants of an old portability
2910 regimen. If the problems come up again, solve them properly,
2911 using autoconf. Specifically: Don't test M_SYSV, and #define
2912 remove to be unlink if it's #defined; don't use remove just
2913 because HAVE_STDC_HEADERS is #defined.
2914 * filesys.h: Add declarations for scm_sys_delete_file.
2915 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2916 files.o, files.h, files.c, and files.x.
2917 * init.c: Don't #include "files.h", and don't call scm_init_files.
2919 Use SCM_P instead of PROTO; the latter intrudes on the user's
2921 * params.h: Deleted; definition of SCM_P moved to...
2922 * __scm.h: ... here, where it replaces PROTO macro.
2923 * libguile.h, smob.h: Don't #include "params.h".
2924 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2925 smob.h: Fix prototypes accordingly.
2926 * Makefile.in: Update dependencies.
2927 (inner_h_files): Remove params.h.
2929 * gc.c: #include "gc.h"; every module should include its header,
2930 to let the compiler cross-check the declarations against the
2933 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2934 simpos.h: #include "libguile/__scm.h".
2936 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2938 * init.c: Don't forget to #include smob.h and init.h.
2939 * Makefile.in: Dependencies updated.
2941 * smob.h: Use PROTO instead of #if __STDC__.
2943 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2945 * __scm.h: Doc fixes.
2947 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2948 <angles>; this allows `make depends' to work properly.
2950 * libguile.h: #include smob.h and pairs.h before the others; they
2951 define typedefs used by other headers.
2953 C files should #include only the header files they need, not
2954 libguile.h (which #includes all the header files); the pointless
2955 recompilation was wasting my time.
2956 * Makefile.in (all .o dependency lists): Regenerated.
2957 * libguile.h: Don't try to get a definition for size_t here...
2958 * __scm.h: Do it here.
2959 * _scm.h: Since this is the internal libguile header, put things
2960 here that all (or a majority) of the libguile files will want.
2961 Don't #include <libguile.h> here; that generates dependencies on
2962 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2963 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2964 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

3055 * unif.c: Get "unif.h", "feature.h", "strop.h", "sequences.h",

3060 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
3061 * weaks.c: Get "weaks.h".
3063 * stackchk.h: #include "libguile/debug.h",
3065 * print.h, read.h: #include "options.h", since everyone who uses
3066 either of these files will need that.
3068 * smob.h: #include "ports.h", "genio.h", and "print.h", since
3069 anyone who uses this file will need them to define the smob
3070 printing functions. Also, get markers.h, since people will need
3071 to #define the mark functions.
3073 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
3074 * ports.h: ... to here.
3076 * ports.h (scm_port_table_size): Explicitly give type as 'int';
3077 don't rely on archaic C default type rules.
3079 * fports.h: #include "libguile/ports.h", since you need that in
3080 order to parse this.
3082 * genio.h: #include "libguile/print.h", because you need that to
3083 parse this; don't bother #including "ports.h", since print.h gets
3086 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
3088 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
3089 this; it's now a reference to an element of *scm_root.
3091 * debug.h: Don't #include "options.h"; the compiler won't be able
3092 to find that once the headers are installed; instead, #include
3093 "libguile/options.h".
3094 * gc.h: Same, with marksweep.h.
3095 * mbstrings.h: Same, with symbols.h.
3096 * scmhob.h: Same, with _scm.h.
3097 * smob.h: Same, with params.h.
3099 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
3100 C files; there's no need for this, and it forces recompilations
3103 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
3105 * error.c (scm_error): declare scm_error_callback.
3107 * error.h: prototype for scm_error_callback.
3109 * __scm.h: define lgh_error.
3110 (SCM_SYSERROR): redefine using lgh_error.
3112 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
3114 * error.c (scm_error): new procedure.
3116 * error.h: prototype for scm_error.
3118 * Makefile.in (install): install scmconfig.h from the current
3119 directory, not $(srcdir).
3121 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3123 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3124 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3125 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
3126 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
3127 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
3128 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
3129 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
3130 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
3131 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3132 vports.h, weaks.h: #include "libguile/__scm.h", not
3133 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
3134 dependencies are within libguile properly.
3136 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3138 * Makefile.in (.c.x): Simplify; there's no need to run this rule
3139 when scmconfig.h doesn't exist.
3141 * load.c (scm_sys_try_load): Correct spelling.
3143 * feature.c (scm_loc_features): Make this static.
3145 * Makefile.in (libpath.h): Omit trailing slash from path. We
3146 shouldn't require it of users, so why put it here?
3148 Move code to initialize and search %load-path from ice-9 to C
3149 code, so we can use the load-path to find the ice-9 boot code;
3150 this makes it easier to run Guile without installing it. See
3151 corresponding changes in guile/Makefile.in.
3152 * feature.c: Move stuff concerned with the load path to load.c.
3153 (scm_compiled_library_path): Deleted.
3154 Don't #include libpath.h here.
3155 * feature.h: Don't mention scm_compiled_library_path.
3156 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
3157 <sys/stat.h>, and <unistd.h> (if present).
3158 (R_OK): #define if the system hasn't deigned to.
3159 (scm_loc_load_path): New variable.
3160 (scm_init_load_path, scm_sys_search_load_path,
3161 scm_sys_try_load_path): New functions.
3162 (scm_init_load): Initialize scm_loc_load_path to point to the
3163 value cell of the Scheme %load-path variable.
3164 * load.h: Add declarations for scm_sys_search_load_path,
3165 scm_sys_try_load_path.
3166 * init.c: Call scm_init_load_path.
3167 * Makefile.in (feature.o, load.o): Dependencies updated.
3169 * load.c, load.h: Rewrite using PROTO macro.
3171 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3173 * gc.c (scm_cellp): New function: C predicate to determine if an
3174 SCM value can be regarded as a pointer to a cell on the heap.
3176 * gc.h: Added declaration of scm_cellp.
3178 * gdb_interface.h: New file: The GDB interface header from the GDB
3181 * gdbint.c: New file: GDB interface.
3183 * gdbint.h: New file: GDB interface.
3185 * libguile.h: Added #include <libguile/gdbint.h>.
3187 * init.c (scm_boot_guile): Added scm_init_gdbint.
3189 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
3190 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
3191 found if object files and source are kept separate).
3193 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
3195 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
3197 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
3199 * configure.in: Don't substitute the values of TCL_SRC_DIR and
3200 TK_SRC_DIR; they're not relevant any more.
3202 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
3203 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
3205 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
3207 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
3208 search path, so we can find the <libguile/MUMBLE.h> headers.
3210 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
3212 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
3213 implicit in the .c.o rule.
3214 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
3217 Put the library path in a header file, instead of passing it on
3218 the command line in every compilation.
3219 * Makefile.in (libpath.h): New target.
3220 (feature.o): Depend on libpath.h.
3221 (clean): Delete libpath.h.
3222 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
3223 * feature.c: ... #include "libpath.h" here.
3224 * .cvsignore: Ignore libpath.h.
3226 Don't install the unwashed masses of Guile header files in the
3227 main #include path; put most of them in a subdirectory called
3228 'libguile'. This avoids naming conflicts between Guile header
3229 files and system header files (of which there were a few).
3230 * Makefile.in (pkgincludedir): Deleted.
3231 (innerincludedir): New variable; this and $(includedir) are enough.
3232 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
3233 (installed_h_files): Divide this up. Now this variable lists
3234 those header files which should go into $(includedir) (i.e. appear
3235 directly in the #include path), and ...
3236 (inner_h_files): ... this new variable says which files appear in
3237 a subdirectory, and are referred to as <libguile/mumble.h>.
3238 (h_files): List them both.
3239 (install): Create innerincludedir, not pkgincludedir. Put
3240 the installed_h_files and inner_h_files in their proper places.
3241 (uninstall): Corresponding changes.
3242 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3243 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3244 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
3245 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
3246 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
3247 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
3248 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
3249 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
3250 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3251 vports.h, weaks.h: Find __scm.h in its new location.
3252 * __scm.h: Find scmconfig.h and tags.h in their new locations
3253 (they're both "inner" files).
3255 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
3257 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
3259 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3261 * posix.c: Doc fixes.
3263 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
3265 * socket.c: Don't include a prototype for inet_aton; just use a
3266 K&R style declaration, to avoid warnings but minimize the chance
3267 of conflicts with the system.
3269 On NextStep, <utime.h> doesn't define struct utime, unless we
3270 #define _POSIX_SOURCE before #including it.
3271 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
3272 * acconfig.h: New comment text for above CPP symbol.
3273 * configure.in: Call it.
3274 * posix.c: #define _POSIX_SOURCE if it seems necessary.
3276 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
3278 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
3279 testing for __EMX__.
3281 * posix.c: #include <libc.h>, if it exists.
3283 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
3284 don't even know if the latter exists.
3286 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
3287 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
3288 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
3290 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
3292 (scm_init_posix): Use them when initializing the Scheme constants
3295 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3297 * Makefile.in (libdir, includedir, bindir): Use the
3298 autoconf-supplied values, instead of deriving them ourselves.
3299 (pkgincludedir, datadir, pkgdatadir): New variables.
3300 (install, uninstall): Put the header files in a special
3301 subdirectory, not in the main search path.
3303 * Makefile.in (ALL_CFLAGS): Provide the proper value for
3304 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
3306 * Makefile.in (IMPLPATH): Deleted; never used.
3308 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
3309 on the Tcl/Tk source any more.
3310 (INCLUDE_CFLAGS): Remove references to the above.
3312 * Makefile.in (version.o): Corrected dependencies.
3314 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
3316 * libguile.h: #include "version.h"
3318 * init.c (scm_boot_guile): Call scm_init_version.
3319 * gscm.c (gscm_run_scm): Call scm_init_version.
3321 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
3322 GUILE_VERSION): AC_DEFINE these.
3323 (acconfig.h): #undef the above symbols.
3325 * Makefile.in (libobjs): Add version.o.
3326 (installed_h_files): Add version.h.
3327 (c_files): Add version.c.
3328 (gen_c_files): Add version.x.
3329 (version.o): New rule.
3330 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
3331 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
3332 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
3333 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,

3339 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
3340 weaks.o): Add version.h to dependency lists.
3341 (markers.o): Remove duplicate rule.
3343 * version.h: New file.
3345 * version.c: New file.
3347 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3349 * symbols.c (scm_strhash): scm_downcase is now a function, not an
3350 array; use it appropriately. Since GCC is quite happy to
3351 subscript functions, it never warned us about this; we should use
3352 -Wpointer-arith in the future. I guess we never tested
3355 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3357 * socket.c: Doc and copyright fixes.
3359 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3361 * debug.c: Fixed and improved gdb support.
3363 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3365 * socket.c: Added declaration of inet_aton to avoid compiler
3366 warning. (Hope this solution is correct.)
3368 * stime.c: Added declaration of ftime. (This is missing in
3371 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
3373 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3375 * Makefile.in (c_files): add strerror.c.
3377 * strerror.c: new file from Emacs' sysdep.c.
3378 maybe configure should also check for sys_errlist.
3380 * configure.in (AC_REPLACE_FUNCS): add strerror.
3382 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3384 * debug.c (scm_init_debug): Added initialization for
3385 scm_evaluator_traps.
3387 * debug.h, debug.c: Various name changes.
3388 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
3389 "debug-options-interface". See commentary in options.c.
3391 * options.h, options.c: Options now have documentation strings.
3392 Also added a long explanatory commentary.
3394 * eval.c, print.h, print.c, read.h, read.c: Modifications to
3397 * gscm.c, init.c, root.c, throw.c: Bug fixes:
3398 last_debug_info_frame is now updated in all cases.
3400 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
3403 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3405 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
3406 Added option STACK_CHECKING.
3408 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3410 * Makefile.in: Added {debug,options,srcprop}.{h,c}
3412 * __scm.h: Removed symbols for debugging support.
3414 * acconfig.h: Added symbols for debugging support.
3416 * configure.in: Added user option for debugging support.
3417 --enable-debug will include the debugging code into libguile.a.
3419 * continuations.c (scm_make_cont): Enlarged the #if 0 around
3420 scm_relocate_chunk_to_heap.
3422 * debug.c: New file: low-level debugging support. It also
3423 includes support for debugging with gdb. (The extensions to gdb
3424 are written by Per Bothner at Cygnus.)
3426 * debug.h: New file: low-level debugging support.
3428 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
3429 argument pairs. Extensive modifications to the debugging
3430 evaluator. Added "SECTION:" commentaries to clarify what happens
3431 when, during double compilation. Renamed EVALIMP --> EVALIM.
3432 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
3433 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
3434 the beginning of the file. New procedure: scm_unmemocopy.
3435 Added some global state variables needed by the debugging
3436 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
3437 check_entry, check_apply, check_exit, debug_options and
3438 evaluator_traps. New acro: undefine.
3440 * eval.h: Renamed EVAL --> XEVAL.
3442 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
3443 --> scm_make_weak_key_hash_table.
3445 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
3446 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
3448 * libguile.h: Conditionally include debug.h
3450 * objprop.c (scm_object_properties, scm_set_object_properties_x):
3451 scm_object_properties shouldn't return handle. `handle' now gets
3452 initialized in scm_set_object_properties_x. scm_object_properties
3453 doesn't any longer create an entry in scm_object_whash.
3455 * options.c: New file: handling of run time options.
3457 * options.h: New file: handling of run time options.
3459 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
3461 * print.c: New procedure: scm_print_options
3463 * print.h: Defines for print options.
3465 * read.c: New procedure: scm_read_options
3467 * read.h: Defines for reader options.
3469 * root.h: Added scm_source_whash among scm_sys_protects.
3471 * srcprop.c: New file: source properties.
3473 * srcprop.h: New file: source properties.
3475 * throw.c (jbsmob): Jump buffers are now correctly allocated.
3476 (Bug found by A. Green.)
3478 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3480 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3482 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
3484 * libguile.h: #include "objprop.h"; I guess this was forgotten.
3486 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
3487 and should be called by the final client.
3489 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
3491 * gc.h: Use the PROTO macro when declaring functions.
3492 * gc.c: Use the PROTO macro when declaring static functions.
3493 Remove the CPP hair around function definitions.
3495 * gc.c (scm_init_storage): Initialize scm_asyncs.
3497 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
3498 preprocessor symbol; "__scm.h" is where it might get #defined.
3499 * __scm.h: Similar: #include <scmconfig.h> before testing
3502 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
3504 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
3506 * init.c (scm_boot_guile): Add init_func argument; call
3507 (*init_func) instead of calling scm_appinit; it's ucky to
3508 hard-code names for the user's procedures.
3509 * init.h (scm_boot_guile): Adjust declaration.
3511 * __scm.h (PROTO): New macro, for declaring functions with
3514 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
3515 eliminate all the __STDC__ conditionals.
3516 (scm_boot_guile): Add declaration.
3517 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
3518 Remove __STDC__ conditionals around function definitions; the
3519 declarations in init.h will provide the same information, more
3522 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
3523 complain about it in the error message; the error message is
3524 adequate without that note, and there's nothing the user can do
3527 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
3529 * Makefile.in (ancillary): Drop def.sed.
3531 * posix.c (scm_init_posix): Use numeric values, rather than
3532 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
3533 F_OK. The symbols aren't available on some systems, and I'm
3534 pretty sure their values are fixed by common widespread practice.
3535 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
3537 More functions unavailable on some systems.
3538 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
3539 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
3541 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3542 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
3543 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
3544 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
3545 stub that signals an error as the #else.
3547 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
3549 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
3551 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
3553 * unif.c: include ramap.h.
3555 * read.c (endif): case_insensative_p renamed case_insensitive_p.
3557 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
3559 * ports.c: include sys/ioctl.h.
3561 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
3563 * configure.in: check for sys/ioctl.h.
3565 * ports.c: include <malloc.h> not "malloc.h".
3567 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3569 * fports.c: remove ttyname and tmpnam declarations.
3571 * posix.c: fewer ttyname declarations.
3573 * fports.c: include <string.h> not "string.h".
3575 * init.c, ioext.c: include string.h and unistd.h.
3577 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3579 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
3580 genio.c, simpos.c, vports.c: include string.h.
3582 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
3584 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
3586 (scm_addr_buffer_size): change type from scm_sizet to int.
3587 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
3588 from scm_sizet to int.
3590 * error.c: include unistd.h.
3592 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
3595 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
3597 * __scm.hd, def.sed: deleted.
3599 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
3601 Changes for NeXT, suggested by Robert Brown.
3602 * configure.in: Call AC_TYPE_MODE_T.
3603 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
3604 NeXT. Put header file list in alphabetical order.
3605 * configure, scmconfig.h.in: Regenerated.
3606 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
3608 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
3611 * acconfig.h: New file, providing documentation for the CPP
3612 symbols defined in configure.in
3613 * acconfig-1.5.h: Removed; superceded by the above.
3615 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
3617 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
3619 * fports.c (scm_open_file): don't return #f, throw error.
3621 * ioext.c (fileno): renamed from %fileno.
3622 (soft-fileno): deleted.
3624 * ports.c (scm_port_revealed): don't need to check for -1 from
3626 (scm_set_port_revealed_x): return unspecified, not #f.
3628 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
3630 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
3632 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
3634 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
3636 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3638 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
3639 This is necessary on Ultrix, and doesn't hurt portability.
3641 * Makefile.in (dist-dir): New target, implementing a new dist system.
3642 (installed_h_files): Put in alphabetical order.
3643 Remove duplicate entries for markers.h and unif.h.
3644 (c_files): Remove duplicate entries for markers.c.
3645 (ancillary): Renamed from anillery; all uses changed. Remove
3646 PLUGIN; it's a directory, and needs special treatment in dist-dir.
3647 Remove all the ../doc/* files; doc/Makefile.in handles that.
3649 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3651 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3652 every if must have an else, or else the whole command has a
3653 non-zero exit code whenever the if's condition is false.
3655 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
3657 * posix.c: include string.h.
3659 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3661 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
3664 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
3665 Remove leading % from scheme names.
3666 Do not return error values, call SCM_SYSERROR or similar.
3668 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
3670 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
3672 * struct.c (scm_init_struct): new file.
3674 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
3676 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
3677 (scm_list_head): added list-head for rapidly chopping argument
3678 lists off of longer lists (and similar).
3680 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
3682 * objprop.c (scm_object_property): assq the cdr of the whash
3683 handle for obj, not the handle itself.
3685 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
3687 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
3688 weak hash tables last of all marking to avoid an obscure gc bug.
3689 WARNING: circular lists stored in a weak hash table will hose us.
3691 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
3693 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
3694 new functions similar to scm_substring_move_left_x and
3695 scm_substring_move_right_x.
3697 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
3699 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
3702 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
3704 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
3706 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
3708 * strports.c (scm_strprint_obj): convenience function. C for
3709 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
3711 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
3712 removed to a separate library
3714 * init.c (scm_boot_guile): copied from guile-tcl.c.
3715 Initialization specific to tcl interpreters removed.
3717 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
3719 * ports.c (scm_ports_prehistory): size malloced here doesn't
3720 matter so long as it is non-0 (got rid of "* 4").
3722 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3724 * gscm.h: gscm_mkarray eliminated (presumably was not being used
3725 since its definition was bogus).
3727 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
3729 * mallocs.[ch]: back again (for rx at least).
3731 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
3733 * ports.c: removed functions relating to the mapping between ports
3734 and descriptors. (That stuff is unix-specific and should be collected
3735 in a separate library).
3737 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
3738 (Tom Mckay@avanticorp.com)
3740 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
3742 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3743 handled correctly (SCM_FREEP was applied to them) -- test for
3744 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
3745 being overwritten with #f. (brown@grettir.bibliotech.com)
3747 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
3749 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

3752 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
3754 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
3755 keys and weak values confused).
3757 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
3759 * list.c (scm_last_pair): map '()=>'()
3761 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
3763 * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
3764 Generalized assoc and hash-table functions.
3765 Factored pairs.c into multiple files.
3767 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
3769 * gscm.c (gscm_run_scm): got rid of objprop.
3771 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
3773 * genio.c (scm_getc):
3774 NOTE: fgetc may not be interruptable.
3776 * procprop.c (scm_stand_in_scm_proc):
3777 NOTE: don't use a alist here.
3778 (scm_set_procedure_properties_x): fix type checking throughout this file.
3780 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
3782 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
3783 after freeing part of the port table.
3785 Thu Feb 29 16:21:17 1996 Tom Lord <lord@beehive>
3787 * strports.c (scm_mkstrport):
3788 * vports.c (scm_make_soft_port): allocate a port table entry
3789 (possibly triggering gc) before setting the tag of the corresponding
3792 * pairs.c (scm_delq_x): never throw an error.
3794 * vectors.c (scm_make_vector): made the default vector fill argument
3795 into '() (much more useful than the previous value, "#unspecified")
3797 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
3799 * ports.c (scm_add_to_port_table): Added fields
3800 to port table entries: file_name, line_num, col.
3801 Update these in open_file, gen_getc and gen_ungetc.
3802 Added procedures to access those fields.
3804 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
3806 * procs.c (scm_make_subr_opt): new entry point for making
3809 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
3811 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
3813 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
3815 * numbers.c (scm_exact_p): This function no longer
3816 implements "integer?".
3818 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
3820 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
3821 (scm_gc_stats): return an assoc of useful data. Replaces "room"
3822 and the stats reporting formerlly built into repl.
3824 * repl.[ch]: removed.
3825 GC statistics keeping moved to gc.c.
3826 Other statistics keeping can be done from Scheme.
3827 REPLS are now written in Scheme.
3829 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
3831 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky
3832 conservatively marked objects).
3834 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
3836 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
3838 * feature.c (scm_compiled_library_path): moved here from repl.c.
3839 This file is for stuff relating specifically to Scheme libraries
3842 * eval.c (scm_m_define): don't give warning about redefinition, don't
3845 NOTE: this should throw a resumable exception with parameters --

3912 initialization to fix a race condition.
3914 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

3938 set the multi_byte flag correctly in symbols. This is wrong.
3939 intern_obbary_soft and msymbolize should take an extra parameter.
3940 Also, weird multibyte symbols don't print correctly.
3941 The weird symbol syntax is also a bit bogus (emacs doesn't quite
