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

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

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

267 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
268 (scm_display_error_message): use RO macros when strings may be RO.
269 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
270 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
271 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

277 SCM_COERCE_SUBSTR to make sure shared substrings are
280 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
282 * error.c (scm_error): Add newline to error message.
284 * init.c (scm_init_standard_ports): Doc fix.
286 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
288 * dynl-shl.c: Completely replaced with new code from Bernard
291 * script.c (scm_ice_9_already_loaded): New variable.
292 (scm_compile_shell_switches): Use it.
294 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
296 * filesys.c (scm_input_waiting_p): add missing third argument to
299 * stime.c (scm_localtime): copy the result of localtime before
300 calling gmtime in case they share a buffer.
301 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
304 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
306 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
308 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
310 * Makefile.am (check-local): New target, which causes 'make check'
311 to run gh_test_c and gh_test_repl, with some trivial input.
312 * Makefile.in: Rgnrtd.
314 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
316 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
319 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
321 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
322 sure how this was supposed to work.
323 (scm_async_click): don't send SCM_TICK_SIGNAL.
324 (scm_init_async): don't initialize %tick-thunk.
326 * the following change doesn't affect the Scheme interface:
327 gc-thunk is called at the end of garbage collection. however it's
328 no longer implemented by pretending it's a signal.
330 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
331 system async corresponding to scm_gc_thunk.
332 * async.h: declare scm_gc_async.
333 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
334 gc-thunk directly, instead of going through a signal handler.
335 (scm_gc_async): new variable, points to the GC system-async.
336 (scm_init_async): save the GC async as scm_gc_async instead
337 of using system_signal_asyncs.
338 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
340 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
342 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
343 Don't screw up if we're interrupted.
344 * Makefile.in: Regeneradet.
346 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
348 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
350 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
351 we're not using AM_INIT_GUILE_MODULE any more.
352 * Makefile.in: Reneregated.
354 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
356 Functions for finding variable bindings, grace à Tim Pierce.
357 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
358 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
360 Get 'make dist' to work again.
361 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
362 * Makefile.in: Regenerated, like a surry without a fringe on top.
364 Changes for reduced Guile distribution: one configure script,
366 * configure.in, configure: Removed.
367 * acconfig.h, acinclude.m4: Moved to parent directory, where the
368 real configure script lives.
369 * Makefile.in, scmconfig.h.in: Regenerated.
371 * init.c: #include "script.h", to get prototype for script.c's
374 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
376 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
377 scm_must_malloc, not raw malloc.
379 * script.c (scm_compile_shell_switches): Dyke out debugging output
382 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
384 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
386 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
387 system has them. Hope this is safe. Previously
388 sys/timeb.h was included if HAVE_FTIME was defined or if
389 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
390 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
392 * ioext.c (scm_setfileno): add missing third argument to
395 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
397 * eq.c (scm_equal_p): Correctly compare strings of different
398 varieties. (Thanks to Tim Pierce.)
400 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
402 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
403 #! block comment must occur on a line all by itself.
405 Move most of the guts of shell command processing into libguile,
406 so guile.c can be very small (and eventuallly auto-generated. (I
407 mean, generated mechanically, not self-generated. Hmm.))
408 * guile.c, script.c, script.h: New source files.
409 * init.c (scm_boot_guile_1): Call scm_init_script.
410 * libguile.h: #include "script.h".
411 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
412 targets, for new executable.
413 (libguile_la_SOURCES): Mention script.c.
414 (modinclude_HEADERS): Add script.h.
415 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
416 not dynamic linking is enabled. This is because we're generating
417 executables now. Move CY_AC_WITH_THREADS call after those, so the
418 values of cy_cv_threads_libs captures the libs chosen above.
419 * Makefile.in, configure, aclocal.m4: Regenerated.
421 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
422 We don't maintain this interface any more, and it just confuses
425 * alloca.c: #include <scmconfig.h>, not <config.h>.
426 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
427 it'll get included in disties.
429 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
431 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
432 be distributed, because they confuse people.
433 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
435 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
437 * configure.in: check for presence of gethostent (not present on
439 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
440 * configure, scmconfig.h.in: Regenerated.
442 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
444 * backtrace.c (scm_backtrace): Split message string across
445 newlines properly. GCC is more tolerant of this than other
448 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
450 Merge threads directory into libguile.
451 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
452 threads.h: New source files.
453 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
454 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
456 (modinclude_HEADERS): Add threads.h, coop-defs.h.
457 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
458 coop-threads.c.cygnus, coop-threads.h.cygnus.
459 * configure.in: If we're using threads, include threads.o in
461 * _scm.h, libguile.h: threads.h lives in this directory now.
462 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
463 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
464 currently used, but brought along for information's sake.
465 * ChangeLog-threads: log from old 'threads' directory.
466 * Makefile.in, configure: Rebuilt.
468 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
470 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
473 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
475 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
477 Merge GH interface library into libguile.
478 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
479 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
480 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
481 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
483 (EXTRA_libguile_la_SOURCES): ... here.
484 (pkginclude_HEADERS): Add variable, to get gh.h installed.
485 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
486 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
487 New variables, describing how to build the gh test programs.
488 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
489 build the test programs, and we probably should have been linking
490 libguile.la against them all along, to support AIX shared libs.
491 Add cflags for threads to CFLAGS; add libs for threads to new
492 variable THREAD_LIBS, used in Makefile.am.
493 * ChangeLog-gh: log from old `gh' subdirectory.
494 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
496 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
498 * acconfig.h: Undo change of Apr 9; including the definition of
499 PACKAGE in the guile headers conflicts with applications' own

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

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

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

622 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
624 * posix.c (scm_mknod): split the mode argument into type and perms
625 arguments, like the extra fields returned by stat.
627 * fports.c (scm_pipob): set the close, free and print procedures.
628 (scm_close_pipe): new procedure.
630 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
631 define them in boot-9.scm
633 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
635 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
636 wan't defined. Don't include fd.h.
638 * Previously fd.h was regenerated whenever configure was run,
639 forcing a couple of files to be recompiled.
641 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
642 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
643 Check for _fileno as well as _file.
645 * ioext.c: don't fd.h.
646 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
649 * Change the stratigy for getting information about errno
650 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
651 generating lists of symbols during the build process, which will
652 not always work, include comprehensive lists in the distribution.
653 To help keep the lists up to date, the "check_signals" and
654 "check_errnos" make targets can be used.
656 * configure.in: don't check for a command to extract errno codes.
657 * Makefile.am: update file lists, remove errnos.list and errnos.c
658 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
659 check_errnos targets.
660 (CLEANFILES): remove errnos.c and errnos.list, add
661 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new

663 * errnos.default: deleted.
664 * cpp_signal.c: new file.
665 * cpp_errno.c: renamed from errnos_get.c.
666 * cpp_err_symbols, cpp_sig_symbols: new files.
667 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
668 * error.c (scm_init_error): #include cpp_err_symbols instead of
670 * posix.c (scm_init_posix): don't intern signal symbols. #include
673 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
675 * strop.c (scm_i_index): allow the lower bound to be equal to the
676 length of the string, so a null string doesn't always give an error.
678 * posix.h: new prototypes.
679 * posix.c (scm_status_exit_val, scm_status_term_sig,
680 scm_status_stop_sig): new functions, as in scsh. They break down
681 process status values as returned by waitpid.
683 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
685 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
686 configure doesn't know about it.
688 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
690 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
692 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
693 which defines C variables with global linkage.
695 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
697 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
700 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
702 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
703 has time to check why this doesn't work well with continuations.
705 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
707 * Fix shell syntax error; some shells won't tolerate
708 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
710 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
712 * posix.c (scm_uname): throw an error if uname fails instead
715 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
717 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
720 * async.c (scm_ints_disabled): definition moved from error.c.
722 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
724 * acconfig.h: Removed PACKAGE.
726 * scmconfig.h.in: Regenerated.
728 * snarf.h: g++ says it's non-portable not to specify the first
729 argument in a varargs declaration. I introduced the first
730 argument by using preprocessor conditionals.
732 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
734 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
735 (scm_freopen): use RO string macros for filename and modes.
736 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.

739 (scm_mknod): use RO string macros for path.
741 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
742 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
744 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
745 use SCM_ROSTRINGP and SCM_ROCHARS.

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

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

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

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

984 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
985 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
986 They should only be included in the library at configure.in's
988 (libguile_la_LDADD): Include the appropriate .lo files here.
989 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
990 so we know when to build them (and their .lo bretheren).
991 * configure.in (LIBLOBJS): New substituted variable. We let
992 configure decide which .o files to include in LIBOBJS, and then
993 put the corresponding list of .lo files in LIBLOBJS. The latter
994 is what we pass to libtool.
995 * Makefile.in, configure: regenerated.
997 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
999 * symbols.c (scm_sysintern0): New function. Contains the core of
1000 old scm_sysintern but doesn't take a second value argument.
1001 (scm_sysintern): Now uses scm_sysintern0.
1002 (scm_sysintern_no_module_lookup): Renamed to
1003 scm_sysintern0_no_module_lookup and doesn't take a second value
1004 argument any longer.
1006 * symbols.h (scm_sysintern0: Added declaration.
1008 * options.c (scm_init_opts): Use scm_sysintern0 instead of
1009 scm_sysintern when interning option keys. Otherwise we risk
1010 destroying the values of already interned variables.
1012 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
1013 scheme-level boolean (use SCM_NFALSEP).
1015 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
1017 (scm_backtrace): New function. (C version of old function from
1018 boot-9.scm) Motivation: Make it possible to display backtraces
1019 without depending on boot-9.scm. (I'm uncertain if this
1020 motivation is good enough...)
1022 * root.h (scm_root_state): Add member the_last_stack_var.
1023 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
1025 * root.c (mark_root): Mark scm_the_last_stack_var.
1027 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
1030 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
1032 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
1033 1. mark_lazy_catch didn't mark the smob.
1034 2. Both functions above have standard variants:
1035 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
1036 free_lazy_catch --> scm_free0.
1038 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
1040 * throw.c (scm_internal_lazy_catch): New function.
1041 (scm_lazy_catch): Rewritten to use it.
1042 (scm_ithrow): Handle the new lazy catch representation.
1043 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
1044 that doesn't have a jmpbuf is a lazy catch clause.
1045 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
1046 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
1047 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
1049 (scm_init_throw): Register the new lazy-catch smob type.
1050 * throw.h (scm_internal_lazy_catch): decl for new function.
1052 * throw.c (scm_internal_catch): Doc fixes.
1054 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
1055 configure.in. Including this might cause problems if applications
1056 that link against libguile include their own copies of alloca, but
1057 if they're using autoconf, they should be adding libguile to LIBS
1058 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
1059 the copy in libguile, and things will be okay. (I think.)
1061 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1063 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
1065 strop.h: move prototypes too.
1067 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
1069 * posix.c (scm_init_posix): don't intern EINTR since it's now done
1072 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
1073 etc. I deleted them from filesys.c long ago, but didn't
1074 notice they were here too (although ineffective since
1075 sys/stat.h wasn't included).
1077 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
1079 * eval.c: Don't define alloca in GCC case. gcc will automatically
1080 use __builtin_alloca if appropriate.
1082 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1084 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
1085 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
1086 that values of automatic variables are preserved. See comments
1087 for safe_setjmp for details.
1089 Change from Thomas Morgan:
1090 * variable.c: Include eq.h.
1091 (var_equal): New function.
1092 (variable_smob): Use var_equal as the discriminator for variables.
1094 * throw.c (s_throw): Remove extraneous declaration.
1096 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
1097 * eval.c: Add necessary CPP cruft to support that.
1098 * configure, Makefile.in, scmconfig.h.in: regenerated.
1100 Change from Thomas Morgan:
1101 * procprop.c (scm_procedure_properties): Convert the Scheme
1102 boolean returned by scm_procedure_p into a C boolean before using
1103 it as a condition for SCM_ASSERT.
1104 (scm_procedure_property): Likewise.
1106 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
1107 indications of Unixness.
1110 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
1112 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
1114 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
1116 * read.c (scm_lreadr): use scm_misc_error to improve one of the
1117 "unknown # object" error messages.
1119 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
1120 (scm_i_index) and declare it static. Add a 'direction' argument
1121 to indicate what way the search should go.
1122 (scm_i_index): throw out-of-range error instead of wrong-type-arg
1124 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
1125 strop.h: remove scm_i_index, scm_i_rindex prototypes.
1127 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1129 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
1131 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
1132 to avoid clash with various scsh forks.
1134 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
1136 The following two changes (ramap.c, throw.c) are motivated by the
1137 apparent unportability of forward declarations of static arrays of
1138 the form `static foo bar[];'.
1140 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
1141 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
1143 * throw.c (scm_throw): Moved above scm_ithrow.
1145 * options.h: Removed the extern declarations of scm_yes_sym and
1146 scm_no_sym since these are static.
1148 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1150 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
1152 * Makefile.am: remove AWK=@AWK@.
1153 Add a rule for generating errnos.list.
1154 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
1156 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
1157 don't extract errnos, just set a variable (avoids the
1158 need to recompile error.c just because configure is run.)
1160 * unif.h: update prototypes.
1161 * unif.c (scm_uniform_array_read,write): change the offset and
1162 length arguments to start and end, for consistency.
1164 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
1166 * ioext.h: update prototypes.
1167 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
1168 scm_read_line_x, it's a more general procedure using an
1169 interface from scsh. read-line and read-line! are now defined
1171 Note that the new read-line trims the terminator
1172 by default, previously it was appended to the returned string. An
1173 optional argument specifies how to process the terminator (scsh
1174 compatible). For the old behaviour: (read-line port 'concat).
1175 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
1176 returns a pair, but is converted to multiple values if the scsh
1179 socket.h: update prototypes.
1180 * socket.c (scm_recvfrom): for consistency with other procedures,
1181 take start and end as separate optional arguments.
1182 (scm_recv, scm_recvfrom): don't allow the second argument
1183 to be a size, only a buffer. Change the scheme names to
1184 recv! and recvfrom!. Don't return the buffer.
1186 * ioext.h, posix.h: move prototypes too.
1187 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
1188 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
1189 "read.h" and "unif.h".
1190 * ioext.c: include "chars.h"
1192 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
1194 * dynl.c: The dynamic linking and module registration functions
1195 are now defined even when dynamic linking is not available for the
1196 host system. Some of their functionality can be done without
1197 dynamic linking; when it's really needed, they throw errors.
1199 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
1201 * configure.in: Only define DYNAMIC_LINKING when one of the system
1202 dependent functions is detected.
1203 * dynl.c (scm_dynamic_func): New function to get the address of a
1204 function in a dynamic object.
1205 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
1206 produced by scm_dynamic_func as the thing to call.
1208 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
1210 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
1211 (scm_register_module_xxx, scm_registered_modules,
1212 scm_clear_registered_modules): New functions.
1214 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
1216 * symbols.c (scm_sysintern): Renamed to
1217 scm_sysintern_no_module_lookup.
1218 (scm_sysintern): New function to take the place of the old
1219 scm_sysintern. It uses the current toplevel lookup closure to give
1220 the symbol its value. This is a temporary hack to put packages
1221 like gtcltk into their own module.
1222 (scm_can_use_top_level_lookup_closure_var): New variable to tell
1223 us whether `scm_top_level_lookup_closure_var' has been initialized
1225 * eval.c (scm_init_eval): Set it.
1227 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
1229 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
1230 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
1232 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
1234 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
1235 scm_sys_dup): deleted: FD capability will be added to other
1237 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
1238 scm_fd_free, fd_smob, scm_intern_fd.
1239 (scm_open): renamed from scm_sys_open. Return a port instead of
1240 an FD object. Make the mode argument optional.
1241 (scm_sys_create): deleted, it's just a special case of open.
1242 (scm_init_filesys): move interning of constants O_CREAT etc.,
1243 here (were previously using SCM_CONST_LONG macro).
1244 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
1246 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
1247 include "fports.h" and <stdio.h>
1248 (scm_stat, scm_select): don't support FD objects.
1250 * error.h: adjust scm_syserror_msg prototype.
1251 * error.c (scm_syserror_msg): take an extra argument for errno.
1252 Using the global value didn't always work, since it could be
1253 reset by procedure calls in the message or args arguments.
1255 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
1256 I don't understand why the check was there (and what about the
1259 * strop.c (scm_string_copy): allow shared substrings to be copied.
1261 * unif.h: corresponding change to prototypes.
1262 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
1263 recognize two new optional arguments: offset and length. Allow
1264 the port argument to be an integer (file descriptor, for scsh).
1265 Include <unistd.h> for "read" prototype.
1267 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
1269 * socket.c: don't include filesys.h.
1271 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
1273 * Makefile.am: add AWK=@AWK@ (?)
1275 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
1277 Add a rule to generate errnos.c from errnos.
1278 * error.c (scm_init_error): include errnos.c.
1279 * errnos_cnvt.awk: new file, converts the list of errno codes to
1281 * errnos_get.c: new file.
1282 * errnos.default: new file, contains errnos to try if they can't
1283 be extracted from errno.h.
1284 * configure.in: if using GCC, try and extract errno codes from
1288 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
1290 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
1291 * Makefile.am: Made libguile into a libtool library.
1292 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
1293 Set libtool_libs to indicate that libguile is a libtool library.
1294 See guile/ChangeLog for details.
1295 * .cvsignore: ignore "*.lo", the libtool library objects.
1297 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1299 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
1300 use htons in getservbyport argument.
1302 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
1304 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
1305 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
1308 * objprop.c (scm_object_property): No need to take the CDR of the
1309 value returned by scm_object_properties, since Aug 20 change.
1311 * configure.in: When checking for struct linger, #include
1312 <sys/types.h> as well as <sys/socket.h>. I've never known
1313 <sys/types.h> to cause any portability problems, and Solaris's
1314 <sys/socket.h> needs it.
1315 * configure: Rebuilt.
1317 I think the Sun compiler has chosen a perverse way to interpret
1318 ANSI declarations combined with K&R definitions. We'll
1319 appease it a little bit. But when it invades France, we fight.
1320 * print.c (scm_iprlist): Change 'tlr' argument to an int.
1321 * print.h (scm_iprlist): Here too.
1322 * numbers.c (scm_divbigdig): Change definition to match
1323 declaration in numbers.h.
1324 * unif.c (scm_makflo): Change definition to match declaration in
1327 * init.c (scm_boot_guile): Don't return the value of
1328 scm_boot_guile_1. This function doesn't return a value;
1329 scm_boot_guile_1 doesn't return a value (or return at all).
1331 * eval.c (unmemocopy): Add a semicolon to appease the Sun
1334 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
1335 compile. I have a feeling this function is a bad idea anyway ---
1336 one should always test for features, not systems.
1338 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
1339 semicolons. Only pure luck kept this from being noticed earlier.
1341 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
1343 * socket.c (scm_recvfrom): Added missing semicolon.
1345 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1347 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
1348 the buffer and start and end positions for scsh networking
1351 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
1353 * configure.in: Revert previous change to this file; the problem
1354 is due to transient automake weirdness.
1355 * configure: Rebuilt.
1357 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
1358 PLUGIN/guile.libs. configure generates the latter from the former.
1359 * Makefile.in: Rebuilt.
1361 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
1362 need this if we install scripts, like guile-snarf.
1363 * configure: Rebuilt.
1365 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1367 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
1369 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
1371 * socket.c (scm_addr_vector): fix faulty scm_listify.
1373 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
1375 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
1376 style block comment is no longer considered an error.
1378 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
1380 * PLUGIN/guile.libs.in: New file.
1381 * PLUGIN/guile.libs: Removed from repository.
1382 * configure.in: Create PLUGIN/guile.libs from
1383 PLUGIN/guile.libs.in. This is for including additonal libraries
1384 needed for dynamic linking.
1385 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
1386 instead of PLUGIN/guile.libs.
1388 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
1390 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
1392 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
1393 occurrences of the given element from the list, not just the
1394 first. This is how the Emacs Lisp functions behave, how the
1395 analogous Common Lisp functions behave, and (I believe) how the
1396 older Maclisp functions worked. I realize that this change may
1397 break code, but it seemed better to break it before the Guile
1400 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
1401 Their prototypes were already present in gc.h, but they weren't
1403 (scm_init_storage): Initialize scm_protects.
1404 * root.c (scm_protects): New element of scm_sys_protects.
1406 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
1408 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1410 * libguile.h: Added #include "libguile/net_db.h".
1412 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
1413 30 change. That file is only meant for communication between the
1414 configuration process and load.c. If code linked against libguile
1415 wants to get at the paths mentioned in libpath.h, it can call
1416 functions declared in load.h.
1418 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1420 * libguile.h: Removed #include "libguile/fdsocket.h"
1422 * net_db.c: Added #include <sys/socket.h>.
1424 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
1426 * filesys.c (scm_input_waiting_p): use select in preference to
1427 FIONREAD, since the latter doesn't detect EOF.
1428 Throw error if neither select nor FIONREAD available.
1430 * socket.c (scm_connect): take a port, not a fd object.
1431 (scm_fill_sockaddr): throw an error if fam is not recognised.
1432 (scm_bind): use scm_fill_sockaddr.
1433 (scm_listen): take a port, not a fd object.
1434 (scm_accept): take and return a port. return #f in the car if
1435 address can't be got
1436 (scm_sock_fd_to_port): new procedure.
1437 (scm_socket): use scm_sock_fd_to_port.
1438 (scm_addr_vector): throw error if unrecognised address type.
1439 take an extra argument with the calling procedure name.
1440 (scm_getsockname): take a port. return #f if address can't be got.
1441 (scm_getpeername): take a port. return #f if address can't be got.
1442 (scm_recvfrom): take a port. return #f for address component if can't
1444 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
1445 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
1447 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
1449 * throw.c (scm_internal_catch): Make body funcs and handler funcs
1450 use separate data pointers, to allow them to be designed
1451 independently and reused.
1452 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
1453 Renamed from catch_body, catch_handler, and uncaught_throw; made
1455 (struct scm_catch_body_data): Renamed from catch_body_data; moved
1457 (scm_catch): Use the above.
1458 (scm_throw): Don't bother printing a message for an uncaught
1459 throw; we establish a default handler in init.
1460 * throw.h (scm_internal_catch): Prototype updated.
1461 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
1463 (struct scm_body_thunk_data): New structure, used as data
1464 argument to scm_body_thunk.
1465 * init.c (struct main_func_closure): New structure, packaging up
1466 the data to pass to the user's main function.
1467 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
1468 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
1469 scm_internal_catch to establish a catch-all handler, using
1470 scm_handle_by_message. This replaces the special-case code in
1472 (invoke_main_func): Body function for scm_internal_catch; invoke
1473 the user's main function, using the main_func_closure pointer to
1474 decide what to pass it.
1475 * root.c (struct cwdr_body_data): Remove handler_proc member.
1476 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
1477 (cwdr_handler): Removed.
1479 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1481 * socket.h (SCM_P): update bind prototype.
1482 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
1483 include "feature.h".
1484 (scm_socket): return a port, not a file descriptor object.
1485 include "fports.h" and <unistd.h>
1486 (scm_bind): take a port, not a file descriptor object.
1487 take an extra argument for address args.
1489 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
1490 INADDR_NONE, INADDR_LOOPBACK.
1492 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1494 * init.c: include net_db.h and not fdsocket.h.
1495 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
1497 * Makefile.am: corresponding changes.
1498 * socket.h: renamed from fdsocket.h, fix names.
1499 * net_db.h: renamed from socket.h, fix names.
1500 * socket.c: renamed from fdsocket.c.
1501 remove _sys from procedure names.
1502 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
1503 add "socket" to features list.
1504 * net_db.c: renamed from socket.c.
1505 remove _sys from procedure names.
1506 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
1507 add "net-db" to features list.
1508 include "net_db.h". don't include <sys/socket.h> or
1511 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1513 * tags.h (scm_tags): Removed comma at end of last enumerator.
1515 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
1517 Don't use GCC extensions to allocate space for debugging frames.
1518 (Here he goes again! Why do we put up with this?!)
1519 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
1520 an scm_debug_info structure, not an in-line array of them. Add
1521 'info' member, to say how many vect elements we've used, for eval
1523 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
1524 a new variable debug_info_end to mark the end of vect, instead of
1525 the address of the 'info' pointer itself.
1526 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
1527 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
1528 (SCM_APPLY): Explicitly allocate space for debug.vect.
1529 * debug.c (scm_m_start_stack): Same, for vframe.vect.
1530 * stacks.c: Adjusted for new debug frame structure.
1531 (RELOC_INFO, RELOC_FRAME): New macros.
1532 (stack_depth, read_frames): Use them, and new scm_debug_frame
1533 element 'info', instead of magically knowing that eval frames have
1534 an info pointer sitting after vect.
1535 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
1537 (scm_init_stacks): Formatting tweaks.
1539 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
1541 Give GCC more control flow information, so it can be sure that
1542 variables aren't used uninitialized.
1543 * error.h (scm_error, scm_syserror, scm_syserror_msg,
1544 scm_sysmissing, scm_num_overflow, scm_out_of_range,
1545 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
1546 scm_misc_error): Tell GCC that these functions never return.
1547 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
1548 out the field type, call abort if SCM_ASSERT returns, to placate
1550 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
1551 scm_wta ever returns. We can't handle this case anyway, and this
1552 gives the optimizer more information.
1553 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
1554 scm_wta ever returns.
1556 In some cases, the code is fine, but GCC isn't smart enough to
1557 figure that out; this usually happens when one variable is only
1558 initialized and used when a particular condition holds true, and
1559 we know that condition will never change within a given invocation
1560 of the function. In this case, we simply initialize the variables
1561 to placate the compiler, hopefully to a value which will cause a
1562 crash if it is ever actually used.
1563 * print.c (scm_iprin1): Initialize mw_pos.
1564 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
1565 * throw.c (scm_ithrow): Initialize dynpair.
1566 * unif.c (scm_uniform_vector_ref): Initialize cra.
1567 * struct.c (init_struct): Initialize prot.
1568 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
1570 * strports.c (scm_eval_0str): Don't return uninitialized garbage
1571 if EXPR contains no expressions.
1573 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
1575 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
1576 cause an infinite loop (???). So much for the algebraic
1577 equivalency of variable-sized arrays and alloca...
1579 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
1581 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
1582 a SCM boolean, not a C boolean.
1584 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
1586 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
1587 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
1588 rules for raising scm_mtrigger. Previously, unfortunate but not
1589 unlikely circumstances could result in almost constant invokation
1590 of the gc. Now, this situations should be less likely, but they
1591 are not prevented completely.
1593 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
1595 * numbers.c (scm_fuck): Procedure removed; looks like old test
1597 * numbers.h: Prototype removed.
1599 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
1601 * debug.h (scm_debug_frame): Change `vect' member from an in-line
1602 array to a pointer, to match my Nov 21 change in eval.c.
1604 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1606 * libguile.h: Added #include "libguile/backtrace.h", #include
1607 "libguile/stacks.h".
1609 * strings.c (scm_string scm_make_string scm_string_ref
1610 scm_string_set_x scm_string_equal_p scm_string_append):
1611 Bugfix according to scm patch from Aubrey Jaffer:
1612 Corrected long-standing
1613 (not (eqv? (integer->char 128)
1614 (string-ref (make-string 1 (integer->char 128)) 0)))
1615 bug found by John Kozak <jk@noontide.demon.co.uk>.
1617 * strports.c, strports.h: Make scm_eval_0str return the value of
1618 the last expression evaluated (previously, it returned void).
1620 * strports.c, strports.h: New function: scm_read_0str. Does what
1623 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1625 * simpos.c (scm_getenv): return #f if string can't be found in the
1626 environment instead of throwing an exception, for compatibility
1627 with numerous other systems.
1629 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
1631 * Makefile.am (.c.x): Use guile-snarf.
1632 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1634 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1636 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1638 * backtrace.c (scm_display_error_message): Made non-static, and
1639 renamed from display_error_message.
1640 * backtrace.h (scm_display_error_message): Added extern decl.
1641 * throw.c (uncaught_throw): Use it to display the error message.
1643 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1645 * inet_aton.c: Use #if 0, not #ifdef 0.
1647 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1649 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1650 to convert the returned value.
1651 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1652 the offset argument.
1654 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1656 Add new interface to catch/throw, usable from C as well as
1658 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1659 (scm_internal_catch): New function, replaces...
1660 (scm_catch_apply): Deleted.
1661 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1662 mechanism which is a bit more code, but can be used nicely from C
1663 and implement the Scheme semantics as well.
1664 (scm_internal_catch): This is the replacement; it's named after
1665 the analogous function in Emacs.
1666 (scm_catch): Reimplemented in terms of the above.
1667 (struct catch_body_data, catch_body, catch_handler): New
1668 functions, used by scm_catch.
1669 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1670 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1671 support for new cwdr.
1673 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1676 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1678 * acconfig.h: Added DYNAMIC_LINKING symbol.
1679 * configure.in: Add option and checks for dynamic linking.
1680 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1681 dynl.h: New files for dynamic linking support.
1682 * Makefile.am (libguile_a_SOURCES):
1684 (modinclude_HEADERS): Added "dynl.h".
1685 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
1687 * init.c (scm_boot_guile_1): Call
1688 scm_init_dynamic_linking to initialize dynamic linking support.
1690 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
1692 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
1693 (as we Schemers say). It needs to be global, so that I can tweak
1694 it for the proper operation of unexec.
1695 (scm_boot_guile_1_live): New variable, see above.
1697 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
1699 * guile-snarf.sh: Removed.
1700 * PLUGIN/guile.libs: Added dependency for -lm.
1701 * acinclude.m4: Renamed from aclocal.m4.
1702 * PLUGIN/greet: Removed.
1703 * Makefile.am, aclocal.m4: New files.
1704 * configure.in: Updated for Automake.
1706 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
1708 * eval.c (scm_definedp): Use top_level_lookup_closure_var
1709 and not top_level_lookup_thunk_var.
1711 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
1713 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
1715 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
1717 * eval.c (scm_definedp): Incompatibly changed to be a builtin
1718 Scheme function, instead of syntax. Single argument is now a
1721 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1723 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1724 scm_ra_divide): Properly terminate statements passed as arguments
1725 to IVDEP macros. (Thanks to Bernard Urban.)
1727 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1728 with non-constant sizes. (Thanks to Bernard Urban.)
1730 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1732 It's an "eval closure", not an "eval thunk." A thunk is a
1733 function of no arguments.
1734 * root.h (struct scm_root_state): Renamed
1735 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1736 (scm_top_level_lookup_closure_var): Renamed from
1737 scm_top_level_lookup_thunk_var.
1738 * root.c (mark_root): Uses changed.
1739 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1740 * init.c (scm_start_stack): Uses changed.
1741 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1742 Change scheme-visible name to *top-level-lookup-closure* from
1743 *top-level-lookup-thunk*.
1745 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1747 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1748 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1750 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1752 * gc.c (struct scm_heap_seg_data): Doc fixes.
1754 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1755 sweeping. Then, prepend each segment's free cells to its
1756 freelist, rather than wiping out the old value. (Thanks to Marius
1759 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1760 scm_check_freelist, scm_debug_newcell): New functions and
1761 variables, for debugging freelist problems.
1762 * pairs.h (SCM_NEWCELL): New debugging version added.
1763 * gc.h (scm_debug_newcell): Added extern declaration, used by
1764 debugging version of SCM_NEWCELL.
1766 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1768 On some systems <libc.h> conflicts with <unistd.h>, and should not
1769 be #included at all.
1770 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1771 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1772 * configure.in: Call it.
1773 * posix.c, filesys.c: Use its results to decide whether or not to
1775 * configure, scmconfig.h.in: Rebuilt with autoconf and
1778 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1780 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1781 pointer to the stdio stream before calling scm_setbuf0, so the
1782 latter will be able to retrieve it. I'm surprised this didn't
1783 segfault earlier. (Thanks to Christopher Lee.)
1785 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1787 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1790 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1792 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1793 number of stack narrowing specifier pairs. The first specifier in
1794 a pair controls inner border, the second the outer border. A
1795 number means cut that number of frames, a procedure object means
1796 cut until that object is found in operator position in a frame.
1798 * root.c (cwdr): Bugfix.
1800 * read.c: Recording of positions disabled by default.
1802 * procs.c (scm_closure_p): New function.
1804 * posix.c (scm_tmpnam): New function.
1806 * load.c: Added #include "throw.h".
1807 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1810 * load.c, load.h (scm_read_and_eval_x): New function.
1812 * eval.c: Renamed debug option "deval" to "debug".
1814 (scm_eval_x): `eval!' is no longer accessible from the scheme
1815 level. Motivation: We can't allow operations which introduce
1816 glocs into the scheme level. Guile's type system can't handle
1817 these as data. Use `eval' or `read-and-eval!' as replacement.
1819 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1820 SCM_CONSP since this is a macro!; Set vframe.prev to
1821 scm_last_debug_frame instead of 0. In this way we can look
1822 "above" the virtual start stack frame if we wish.
1823 (scm_debug_hang): New function: Useful for debugging Guile in
1824 certain tricky situations. Will probably be removed later...
1826 * debug.h: Changed semantics of debug option "backtrace". This
1827 option now only indicates whether we want automatic backtrace at
1830 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1832 * ports.c: #include "filesys.h"
1833 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1835 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1836 Motivation: This is system specific code which is related to file
1837 I/O. It also may use select. Added code by Gary Houston to
1838 detect presence of character in stdio buffers.
1840 * libguile.h: #include "libguile/libpath.h"
1842 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1843 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1844 SCM_SITE_DIR; Install libpath.h among the other include files.
1846 * load.c, load.h (scm_sys_package_data_dir): New function.
1848 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1850 * stacks.h: Bugfix: Don't use tail-array length field as stack
1851 length field! This screwed GC.
1853 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1855 * _scm.h: Added #ifndef around definition of macros min and max.
1857 * __scm.h: Added hooks for threads to plugin to in ints protection
1858 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1859 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1860 the main code in these macros duplicated and spread over multiple
1861 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1862 SCM_THREAD_SWITCHING_CODE.
1864 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1866 * snarf.h: New file.
1867 * guile-snarf.sh: New file.
1868 * Makefile.in (inner_h_files): Added snarf.h
1869 (ancillary, install, uninstall, distclean): Added actions for
1871 (.c.x): Use guile-snarf.
1872 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1873 (gen_c_files): Note that these depend on guile-snarf.
1874 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1875 now in "snarf.h". Added #include "snarf.h" to get them.
1876 * libguile.h: Added #include "snarf.h".
1877 (Patches applied and tweaked by Jim Blandy.)
1879 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1881 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1882 standards suggest against providing prototypes for system
1883 functions. Thanks to Greg Troxel.
1885 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1887 * strports.c (scm_eval_0str): New function.
1888 #include "read.h", to get prototype for scm_read.
1889 * Makefile.in (strports.o): Update dependencies.
1890 * strports.h: New prototype.
1892 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1893 scheme name from "int?" to "integer?". It seems to do the job.
1894 * numbers.h: Rename prototype too.
1895 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1898 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1899 scm_num_eq_p): Rename these according to R4RS conventions: call
1900 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1901 to making libguile R4RS compliant without ice-9...
1903 * load.c (scm_sys_search_load_path): Search for files under all
1904 extensions listed in the %load-extensions variable. If FILENAME
1905 is absolute, return it unchanged, without searching the load path.
1906 (scm_loc_load_extensions): New variable, pointing to
1907 %load-extensions' value cell.
1908 (scm_init_load): Initialize it, and the value it points to.
1909 (scm_primitive_load_path): Improve error reporting.
1911 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1912 of new Scheme variable %load-hook.
1913 (scm_primitive_load): Apply %load-hook to filename.
1915 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1917 * configure.in: add tests for figuring out whether buffered data
1918 is available in a FILE structure, which is needed by char-ready.
1920 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1923 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1924 exceptions using misc_error instead of syserror. It seems a bit
1925 odd to throw an exception if a string can't be found in the
1926 environment, but it's consistent with open-file, stat etc.
1927 (simpos.h): remove sys_ from getenv.
1929 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1930 occurs, throw an error instead of returning errno. Return value
1932 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1934 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1936 * filesys.c (scm_stat2scm): derive file type and permissions from
1937 the stat mode and append them to the returned vector.
1938 There isn't much overhead in doing this and it avoids the need to
1939 work with S_IRUSR et al. in Scheme.
1940 Define symbols scm_sym_regular etc.
1941 (scm_init_filesys): don't intern S_IRUSR etc.
1943 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1944 and s_primitive_load_path.
1946 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1948 * error.h: don't declare error symbols. prototype for scm_misc_error.
1950 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1953 * error.c: use SCM_SYMBOL to set up error keys.
1954 scm_misc_error: new procedure.
1956 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1958 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1959 between `#!' and `!#' is ignored.
1960 (skip_scsh_block_comment): New function.
1962 * feature.c (scm_set_program_arguments): New argument, FIRST.
1963 * feature.h: Update prototype.
1964 * init.c (scm_boot_guile_1): Pass new argument to
1965 scm_set_program_arguments.
1967 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1969 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1970 (scm_boot_guile): Call scm_set_program_arguments here, later than
1971 the old initialization.
1973 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1974 initialization procedure.
1975 - Delete in, out, err arguments; there are other perfectly good
1976 ways to override these when desired.
1977 - Delete result argument; this function shouldn't ever return.
1978 - Rename init_func argument to main_func, for less confusion.
1979 - Delete boot_cmd argument; main_func is more general.
1980 -Add 'closure' argument, to help people pass data to main_func
1981 without resorting to global variables.
1982 - Abort if reentered; don't bother returning an error code.
1983 - Call scm_init_standard_ports to set up the default/current
1984 standard ports; no need to pass them to scm_start_stack.
1985 - Remove code to evaluate the boot_cmd, and start the repl; let
1986 the user do something like that in main_func if they want.
1987 - Remove code to package up a return value; main_func can do any
1989 - Call exit (0), instead of returning.
1990 (scm_start_stack): Don't initialize the I/O ports here; that's
1991 weird. Delete in, out, err arguments. Move guts to
1992 scm_init_standard_ports, scm_stdio_to_port.
1993 (scm_init_standard_ports): New function, to set up current and
1994 default standard ports.
1995 (scm_start_stack, scm_restart_stack): Make these static.
1996 * init.h (scm_boot_guile): Adjust declaration.
1997 (scm_start_stack, scm_restart_stack): Remove externally
1998 visible declarations for these.
1999 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
2001 * fports.c (scm_stdio_to_port): New function. Its guts used to be
2002 written out several times in scm_start_stack.
2003 * fports.h: New declaration for the above.
2005 * feature.c (scm_set_program_arguments): New function.
2006 * feature.h: New declaration for the above.
2008 * ports.c: Formatting tweak.
2010 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
2012 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
2013 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
2014 for obtaining the address of a car or cdr field. Motivation:
2015 &SCM_CXR make assumptions about the internal structure of the
2018 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
2019 Motivation: see SCM_CXRLOC.
2021 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
2022 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
2023 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
2024 Motivation: Safer use. Some other macros are defined in terms of
2025 these operations. If these are defined using the SCM_SETCXR
2026 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
2027 to inefficiency and an <e1> with side-effects could potentially
2028 break. Also, these particular operations are heavily utilized in
2029 the garbage collector. In unoptimized code there will be a
2032 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
2033 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
2034 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
2035 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
2036 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
2037 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
2038 vports.c: Cleaned up use of pairs: Don't make any special
2039 assumptions about the internal structure of selectors and
2040 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
2041 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
2042 (Among other things, this change makes it easier to build Guile
2043 with certain compilers which have problems with casted lvalues.)
2045 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2047 * stacks.c: Improve selection of relevant stack frames when making
2048 a stack object. Introduce one level of indirection in the stack
2049 object to make it possible to "narrow" to a certain region of the
2050 stack. This facilitates making use of more clever algorithms (not
2051 implemented) for selecting relevant frames and gives a cleaner
2052 design since selection of frames can be done independently of
2053 extraction of frames from the real stack.
2054 (scm_stack_id): Also take #t as argument which means look at
2057 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
2058 Turn n_tail into an integer directly representing current number
2059 of frames in stack. Add field tail.
2061 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
2063 * debug.c (scm_make_memoized): Made it available at scheme level.
2064 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
2065 SCM_NIMP before applying heavier predicates in argument checking.
2066 (scm_local_eval): Also take memoized object as argument.
2068 * backtrace.c (scm_display_error): Just a safety measure: Stacks
2069 aren't created with zero length, but should such a strange
2070 creature suddenly turn up...
2072 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
2074 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
2075 `del', for the sake of C++ compilers. (Patch applied by JimB.)
2077 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
2079 * variable.c (scm_make_variable): Make the name hint optional, as
2081 (anonymous_variable_sym): Renamed from variable_sym. All uses
2084 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
2085 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
2086 of scm_primitive_load_path was also changed to
2087 "primitive-load-path", from "%try-load-path". Callers changed.
2088 We'd like to respect the convention that a function named
2089 "try-mumble" should behave just like the function called "mumble",
2090 but return #f instead of signalling some error.
2091 * load.h: Rename prototypes.
2093 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2095 * print.c (make_print_state, grow_print_state), print.h: Modified
2096 the print state representation: Don't use a tail array for
2097 recording of circular references. Resizing of the print state
2098 structure invalidates the print state pointer. To avoid passing
2099 around an indirect print state reference to all printing
2100 functions, we instead let the print state reference a resizable
2103 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2105 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
2106 Don't crash when passed an improper list terminated by a
2107 non-immediate value.
2109 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
2111 Allocate data for structures on an eight-byte boundary, as
2112 required by the tagging system.
2113 * struct.c (alloc_struct): New function.
2114 (scm_make_struct, scm_make_vtable_vtable): Call it.
2115 * struct.h (scm_struct_n_extra_words): Bump to 3.
2116 (scm_struct_i_ptr): New "field".
2117 * gc.c (scm_gc_sweep): When we need to free the data, use the
2118 information stored by alloc_struct to find the beginning of the
2119 block allocated to the structure, so we can free it.
2121 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2123 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
2126 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
2127 (scm_debug_info): New member: id.
2129 * stacks.c: Stacks are now represented as structs; Stacks have an
2130 id given to them by `start-stack'.
2131 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
2133 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
2134 Changed stack representation.
2136 * debug.c (scm_procedure_name): Try procedure property `name' for
2137 compiled closures aswell.
2139 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
2141 * eval.c: scm_i_name moved to gsubr.c
2142 (scm_m_define): Record names of all kinds of procedure
2143 objects. (Earlier, only closures were recorded.)
2145 * procprop.h: Added declaration of scm_i_name.
2147 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
2148 (scm_make_gsubr): Record names of compiled closures.
2150 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2152 * debug.c, debug.h: Removed obsolete code.
2154 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
2155 stacks.c: Renamed regs --> scm_contregs.
2157 * print.c (scm_free_print_state): Cleanup print state before
2158 returning it to pool. It is better to do it here than in
2159 scm_prin1 since scm_prin1 is called often.
2161 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
2162 s_set_source_property_x): Check that first argument is a pair or a
2165 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
2166 scm_i_line, scm_i_column and scm_i_breakpoint global.
2168 * init.c: Added #include "backtrace.h" and #include "stacks.h".
2169 (scm_boot_guile_1): Added calls to scm_init_backtrace and
2172 * debug.h: Added debug object smob declaration and macro
2175 * configure.in: Build with backtrace.o and stacks.o if debug
2178 * Makefile.in: Added entries for new files: backtrace.c,
2179 backtrace.h, stacks.c and stacks.h.
2181 * symbols.c (scm_sym2ovcell): Fixed documentation.
2183 * _scm.h (min, max): Added.
2185 * async.c: Moved `min' macro to _scm.h.
2187 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
2188 SCM_BACKTRACE_INDENT.
2190 * eval.c: Added new debug options `maxdepth' and `indent'.
2192 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
2194 * print.h: Added selector SCM_PRINT_STATE.
2196 * print.c: New functions: scm_make_print_state,
2197 scm_free_print_state.
2199 * print.h: Added declarations for scm_make_print_state,
2200 scm_free_print_state.
2202 * debug.c (scm_m_start_stack): New acro.
2204 * debug.h: Small cleanup.
2206 * init.c (scm_boot_guile_1): Moved scm_init_debug below
2209 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

2229 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
2230 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
2231 declare functions with prototypes. (Patch thanks to Marius
2234 More prototype-related changes from Marius Vollmer:
2235 * gdb_interface.h: Wrapped header file in #ifdef/#endif
2236 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
2237 * ports.h (ptobfuns): Added prototypes. This means some casting in
2239 * fports.c: Added casts for initializations, since the functions
2240 are defined to take FILE * as their stream argument, not SCM.
2241 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
2242 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
2243 to `char *str_data' to conform to prototype.
2245 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2247 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
2249 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
2251 * stime.c, stime.h: use SCM_P method.
2253 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2255 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
2256 be given at least two arguments. Insist that lst's last element
2257 be a list, but don't make any requirements of its predecessors.
2259 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2261 * eval.c (scm_nconc2last): Revert last change; there seems to be
2262 other stuff going on here.
2264 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2266 * eval.c (scm_nconc2last): Make sure that each element of lst
2267 (which is a list of argument lists, except for the tail) is a
2268 proper list, i.e., finite and terminated by '().
2270 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2272 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
2275 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
2276 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
2279 * vectors.c (scm_make_vector): Fill vectors with the undefined
2280 value, to help make Guile Scheme code more portable to other
2283 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
2284 * symbols.h, tags.h: Doc fixes.
2286 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
2288 * async.c (scm_take_signal): Doc fixes.
2290 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
2292 * numbers.c (scm_divbigint): When the remainder is zero, we don't
2293 want to subtract it from the modulus; we just want to leave it
2296 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
2298 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
2301 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
2303 * throw.c (scm_catch_apply): Finished implementation of
2306 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2308 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
2310 (scm_init_filesys): set "i/o-extensions" feature.
2313 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
2315 * Makefile.in (root.o): Correct dependencies.
2317 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
2319 * Makefile.in: Added dependency entry for root.o.
2321 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
2322 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
2324 * init.c (scm_start_stack): Set initial root continuation number
2327 * procs.c: New function: scm_thunk_p.
2329 * procs.h: Added declarations of scm_thunk_p.
2331 * root.c: Renamed `call-with-new-root' -->
2332 `call-with-dynamic-root'.
2333 (cwdr): Removed allocation of new root state. This should be done
2334 separately by use of scm_make_root.
2335 (scm_apply_with_dynamic_root): New function: Does what it
2336 sounds like. Needed when spawning threads.
2338 * root.h: Added member last_debug_frame to root state.
2339 Added #include "libguile/debug.h"
2341 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
2342 arguments. The motivation is that code in root.c needs catch
2343 functionality, and we want to avoid code duplication.
2344 New functions: scm_catch, scm_lazy_catch. These are wrappers for
2345 scm_catch_apply. scm_lazy_catch is intended to introduce catch
2346 handlers that run without popping the stack into the dynwind
2349 * throw.h: Added prototypes for scm_catch_apply and
2352 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2354 * root.h (scm_root, scm_set_root): Decouple thread support details
2355 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
2356 SCM_SET_THREAD_LOCAL_DATA.
2358 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
2359 and tortoise scanning loop.
2361 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
2363 * Makefile.in: Rebuild dependencies.
2365 * libguile.h: #include "libguile/print.h" before "smob.h", since
2366 the latter uses the print_state structure.
2368 * throw.c (scm_ithrow): Use the correct variable when checking to
2369 see if a given element of scm_dynwinds is a valid catch.
2371 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
2372 structure, abort; don't just silently ignore the garbage.
2374 * _scm.h: #include "print.h" here, since it seems to be used just
2376 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
2377 strports.c, unif.h: Don't #include "print.h".
2379 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2381 * feature.h (scm_loc_features): Removed external declaration.
2382 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
2384 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2386 * feature.c (scm_init_feature): Added threads feature (needs to be
2387 initialized here, since features doesn't exist when
2388 scm_init_threads is called).
2390 * libguile.h: Added #include "libguile/../threads/threads.h".
2391 (This is a kludge to get thread support working. This should be
2394 * configure.in, acconfig.h: Added flags for thread support.
2396 * scmsigs.c: Define `signal' to be `pthread_signal' if using
2399 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
2400 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
2403 * _scm.h: Added conditional #include "threads.h"
2405 * __scm.h (SCM_ASYNC_TICK): Added call to macro
2406 SCM_THREADS_SWITCHING_CODE.
2408 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
2409 allocate the basic dynamic root object.
2410 (scm_boot_guile): Added call to scm_init_root.
2412 * root.c, root.h: Added root smob.
2413 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
2414 functions: Implements dynamic roots mostly according to spec in
2415 SCM manual. Main difference is that the second argument is a
2416 throw handler rather than an error "thunk".
2418 * root.h: Added declaration of scm_init_root.
2420 * root.c: Added #include "genio.h", #include "smob.h", #include
2421 "pairs.h", #include "throw.h", #include "dynwind.h", #include
2423 (scm_init_root): Added #include "root.x".
2425 * throw.c: Added #include "stackchk.h"
2426 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
2427 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
2428 can be used in scm_call_with_new_root; Added reenabling of stack
2429 checking when catching a throw.
2431 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
2433 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
2435 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
2436 element is not found, as per R4RS.
2438 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2440 * list.c: Doc fixes throughout.
2442 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2444 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
2445 declare the char * to be const. Avoids a warning in rgx.c.
2447 * ports.h: spelling fix.
2449 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
2452 * load.c (scm_sys_try_load_path): throw an error if file not found
2453 (like it says it in NEWS).
2455 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2457 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
2458 PROPS slot to '(), not #f; it's an empty alist.
2460 * throw.h, throw.c: Use SCM_P instead of #if hair.
2462 Remove special support for uncaught throws; see throw.c for
2464 * throw.c (uncaught_throw): New function.
2465 (scm_ithrow): Call uncaught_throw if we don't find a throw
2466 target; don't mess with scm_bad_throw_vcell.
2467 (scm_bad_throw_vcell): Variable deleted.
2468 (scm_init_throw): Don't initialize it.
2470 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
2473 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2475 * numbers.c (scm_istr2int): If the number is short (as most
2476 numbers are), just call scm_small_istr2int to deal with it.
2477 (scm_small_istr2int): New function, created by un-#ifdefing the
2478 non-bignum version of scm_istr2int and renaming it.
2480 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
2482 * load.c (scm_sys_try_load): don't check whether value returned
2483 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
2484 Change the Scheme name from %try-load to primitive-load.
2486 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
2487 Can avoid passing a message, allowing it to be derived in the
2488 error handler (e.g., if we want to throw to the key both from
2491 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
2493 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
2494 references now have a new appearance which is more compact and
2495 also gives a clue about what the target of the reference is.
2496 By setting parameters in the print state, more fancy printing can
2497 be achieved. This is used by the (not yet commited) backtrace
2500 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
2502 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
2505 * print.c: Added #include "struct.h". Removed function
2508 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
2509 scm_iprin1. Removed prototype for scm_prlist.
2511 * arbiters.c (prinarb),
2512 async.c (print_async),
2513 debug.c (prindebugobj, prinmemoized),
2514 eval.c (prinprom, prinmacro),
2515 filesys.c (scm_fd_print, scm_dir_print),
2517 mallocs.c (prinmalloc),
2518 numbers.c, numbers.h (scm_floprint, scm_bigprint),
2519 smob.h (scm_smobfuns),
2520 srcprop.c (prinsrcprops),
2522 unif.c, unif.h (scm_raprin1, rapr1),
2523 variable.c (prin_var): Changed argument `int writing' to
2524 `scm_print_state *pstate'.
2526 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
2527 that it will be called before scm_init_print.
2529 * print.c (scm_prin1): Print states are now allocated when calling
2530 scm_prin1 and then passed around to all printing functions as an
2531 argument. A cache `print_state_pool' enables reuse of print
2533 (scm_make_print_state): New function.
2534 (scm_iprin1): Adaption to print states.
2535 (scm_iprlist): An initial "hare and tortoise" scan brings down
2536 time complexity to O (depth * N). (Better time complexity will be
2537 achieved when the printing code is completely rewritten.)
2539 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2541 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
2542 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
2543 it gets done whether or not the cache variable has a value.
2545 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2547 Distinguish #f and ().
2548 * __scm.h: #undef SICP.
2549 * pairs.h (SCM_EOL): Delete this definition, equating it with
2551 * tags.h (SCM_EOL): Give it a new definition here; I think I found
2552 the value it used to have. Doc fixes, too.
2554 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
2556 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
2557 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
2558 Lord's implementation of structs, allowing for tail arrays as
2559 described in the manual. Also fixed some bugs. (Both the interface
2560 and the implementation should be improved.)
2562 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
2564 * print.c, print.h: Closures now print like #<procedure foo (x)>.
2565 People who whish to see the source can do `(print-enable 'source)'.
2566 Removed #ifdef DEBUG_EXTENSIONS.
2568 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2570 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
2571 integer (assuming for now accepting an integer is a good thing).
2573 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2574 %S will be used instead for write'ing arguments.
2576 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2577 asserts. fix a few other asserts.
2578 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2579 scm_uniform_vector_ref, scm_array_set_x,
2580 scm_dimensions_to_unform_array): change args in
2581 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2582 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2583 scm_substring_fill_x): likewise.
2584 gsubr.c (scm_gsubr_apply): likewise.
2585 eval.c (SCM_APPLY): likewise.
2587 * eval.c (4 places): replace scm_everr with lgh_error or
2590 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2591 scm_memory_error): new procedures.
2592 scm_everr: deleted. can use scm_wta, dropping first two args.
2593 scm_error: convert NULL subr to SCM_BOOL_F.
2595 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2598 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2601 * error.c, error.h: new error keys: scm_arg_type_key,
2602 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2604 scm_wta: reimplement using lgh_error instead of scm_everr.
2606 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2608 * gdbint.c: scm_lread now has one more argument.
2610 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2611 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2612 loading source from non-file ports, which, e. g., happens when
2613 using the Emacs interface).
2615 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2618 * read.c: Added code for recording of positions of source code
2619 expressions; New functions: recsexpr, scm_lreadrecparen;
2620 _scm_make_srcprops --> scm_make_srcprops
2621 (scm_flush_ws): Removed updating of positions counters. This work
2622 is already done by scm_gen_getc
2624 * read.h: Added prototype for scm_lreadrecparen
2626 * print.c: Added #include "alist.h"
2628 * eval.c: Added #include "hash.h"
2630 * eq.c: Added #include "ramap.h"
2632 * options.c: Documentation fixes.
2634 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
2635 (scm_init_srcprop): Adjusted size of initial source-whash. Name
2636 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2637 --> scm_make_srcprops
2639 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2640 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2641 function calls in the definition of the whash access macros.
2643 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2645 * init.c (scm_boot_guile): Add level of indirection to
2646 scm_boot_guile_1() to ensure that stack base pointer is properly
2647 initialized. There was no guarantee that variable i was the
2648 highest/lowest variable on stack (i.e. the call frame of
2649 scm_boot_guile was not completely protected from gc).
2651 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2653 * ports.h (scm_port_table): put back file_name, it will be used to
2654 support debugging. Undo related changes in fports.c, ioext.c,
2657 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2659 * ports.h (scm_port_table): remove file_name member for now, it seems
2661 * fports.c (scm_open_file): don't set file_name in PTAB.
2662 (prinfport): don't use file_name in PTAB.
2663 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2664 * ports.c (scm_add_to_port_table): don't intialize file_name.
2665 (scm_port_file_name): remove for now.
2666 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2668 * fports.h (scm_mkfile): prototype deleted.
2669 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2671 * debug.c, unif.c: use scm_out_of_range instead of
2672 wta for range errors (ASSERT still needs work).
2674 * error.c, error.h (scm_out_of_range): new procedure.
2676 * error.c, error.h (scm_out_of_range_key): new key.
2678 * posix.c (scm_sync): #else was missing.
2680 * error.c, error.h: append _key to names scm_num_overflow and
2683 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2684 of consing an empty list.
2685 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2686 of macros, saves code and string space.
2687 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2688 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2689 lower case. Rename scm_syserror_m to scm_syserror_msg.
2690 error.h: prototypes for new procedures.
2692 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2694 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2696 * error.c, error.h: setup scm_num_overflow key.
2698 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2699 Remove definition of SCM_OVSCM_FLOW.
2701 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2703 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2704 explicit message and args.
2706 * error.c, error.h, __scm.h: change system_error_sym to
2709 * error.c (system_error_sym): remove leading %% from the Scheme name
2712 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2714 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2716 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2717 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2718 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2719 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2720 renamed. (These were introduced by unsupervised name
2723 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2725 * print.c: Added code for detection of circular references during
2726 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2727 a hook for printing of closures (accessible via print options).
2728 This leads to a split of calls to scm_iprin1 into two classes:
2729 elementary print operations (e. g. the code which prints a smob)
2730 still use scm_iprin1 while top level calls (like scm_display) use
2731 scm_prin1. scm_prin1 begins by clearing the data structure used
2732 to record reference information.
2734 * print.h: Added declarations of scm_prin1 and scm_prlist.
2736 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2738 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2740 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2742 * error.c (err_head): scm_iprin1 --> scm_prin1
2744 * debug.c: Adjusted header comment.
2748 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2750 * strerror.c: Doc fix.
2752 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2754 * gdbint.c (gdb_read): Now possible to run during GC.
2755 (unmark_port, remark_port): New functions.
2757 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2759 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2760 of allocating a new string object. Also, increase size by
2761 the factor 2 instead of 1.5.
2763 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2765 * __scm.h (SCM_P): Corrected to run under traditional C.
2767 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2770 * async.c: Calls to scm_sysintern corrected.
2772 * async.h (scm_async_clock): Redundant declaration removed.
2774 * continuations.c (scm_dynthrow): Redundant declaration removed.
2776 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2777 Definition typos corrected.
2779 * debug.h: Missing declarations of functions in debug.c added
2782 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2783 Missing declarations to functions in eval.c added.
2785 * filesys.c: Possibly uninitialized variable rv.
2787 * gc.h (scm_object_addr, scm_unhash_name): Missing
2788 declarations of functions defined in gc.c added.
2790 * genio.c: Possible typos str_data -> wstr_data. ???
2792 * genio.c: Possibly unintended shadowing of local variable
2793 `int c' (gotos out of scope of inner `c'). ???
2795 * init.c: Uninitialized `SCM last' may be used.
2797 * ioext.h: (scm_sys_isatty_p): Typo.
2799 * list.h (scm_list_head): Missing prototype for function in
2802 * numbers.c (scm_two_doubles): Changed from extern to static
2803 (is used only within numbers.c).
2805 * numbers.h: Repeated declarations removed.
2807 * ports.h (scm_close_all_ports_except): Declaration for the
2808 function defined in ports.c added.
2810 * posix.h: Missing declarations added.
2812 * procs.h (scm_make_subr_opt): Missing declaration added.
2814 * socket.h (scm_sys_gethost): Missing declaration added.
2816 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2818 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2819 Missing declarations added.
2821 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2823 * struct.c: Uninitialized variable `SCM answer' may be used.
2825 * unif.c (l2ra): Declaration prototype.
2827 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2828 defined in ramap.c).
2830 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2831 Redundant declarations removed (they are in ramap.h).
2833 * variable.h (scm_make_udvariable,
2834 scm_make_undefined_variable): Declaration corrected to
2835 correspond variable.c.
2837 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2838 Missing declarations added.
2840 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2842 * Makefile.in (distclean): Don't forget to delete fd.h.
2844 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2846 * fd.h.in, tags.h: Trivial cleanups.
2848 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2849 marksweep.h just declared functions from gc.c.
2850 * gc.h, libguile.h: Don't #include "marksweep.h".
2851 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2852 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2853 dependencies updated.
2855 * libguile.h: Don't #include "files.h"; it's been deleted.
2857 * files.c (scm_sys_delete_file): Moved to filesys.c.
2858 File is now empty; deleted.
2860 * filesys.c: scm_sys_delete_file is now here. Remove
2861 #if's; they seem to rely on remnants of an old portability
2862 regimen. If the problems come up again, solve them properly,
2863 using autoconf. Specifically: Don't test M_SYSV, and #define
2864 remove to be unlink if it's #defined; don't use remove just
2865 because HAVE_STDC_HEADERS is #defined.
2866 * filesys.h: Add declarations for scm_sys_delete_file.
2867 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2868 files.o, files.h, files.c, and files.x.
2869 * init.c: Don't #include "files.h", and don't call scm_init_files.
2871 Use SCM_P instead of PROTO; the latter intrudes on the user's
2873 * params.h: Deleted; definition of SCM_P moved to...
2874 * __scm.h: ... here, where it replaces PROTO macro.
2875 * libguile.h, smob.h: Don't #include "params.h".
2876 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2877 smob.h: Fix prototypes accordingly.
2878 * Makefile.in: Update dependencies.
2879 (inner_h_files): Remove params.h.
2881 * gc.c: #include "gc.h"; every module should include its header,
2882 to let the compiler cross-check the declarations against the
2885 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2886 simpos.h: #include "libguile/__scm.h".
2888 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2890 * init.c: Don't forget to #include smob.h and init.h.
2891 * Makefile.in: Dependencies updated.
2893 * smob.h: Use PROTO instead of #if __STDC__.
2895 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2897 * __scm.h: Doc fixes.
2899 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2900 <angles>; this allows `make depends' to work properly.
2902 * libguile.h: #include smob.h and pairs.h before the others; they
2903 define typedefs used by other headers.
2905 C files should #include only the header files they need, not
2906 libguile.h (which #includes all the header files); the pointless
2907 recompilation was wasting my time.
2908 * Makefile.in (all .o dependency lists): Regenerated.
2909 * libguile.h: Don't try to get a definition for size_t here...
2910 * __scm.h: Do it here.
2911 * _scm.h: Since this is the internal libguile header, put things
2912 here that all (or a majority) of the libguile files will want.
2913 Don't #include <libguile.h> here; that generates dependencies on
2914 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2915 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2916 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

3013 * weaks.c: Get "weaks.h".
3015 * stackchk.h: #include "libguile/debug.h",
3017 * print.h, read.h: #include "options.h", since everyone who uses
3018 either of these files will need that.
3020 * smob.h: #include "ports.h", "genio.h", and "print.h", since
3021 anyone who uses this file will need them to define the smob
3022 printing functions. Also, get markers.h, since people will need
3023 to #define the mark functions.
3025 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
3026 * ports.h: ... to here.
3028 * ports.h (scm_port_table_size): Explicitly give type as 'int';
3029 don't rely on archaic C default type rules.
3031 * fports.h: #include "libguile/ports.h", since you need that in
3032 order to parse this.
3034 * genio.h: #include "libguile/print.h", because you need that to
3035 parse this; don't bother #including "ports.h", since print.h gets
3038 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
3040 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
3041 this; it's now a reference to an element of *scm_root.
3043 * debug.h: Don't #include "options.h"; the compiler won't be able
3044 to find that once the headers are installed; instead, #include
3045 "libguile/options.h".
3046 * gc.h: Same, with marksweep.h.
3047 * mbstrings.h: Same, with symbols.h.
3048 * scmhob.h: Same, with _scm.h.
3049 * smob.h: Same, with params.h.
3051 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
3052 C files; there's no need for this, and it forces recompilations
3055 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
3057 * error.c (scm_error): declare scm_error_callback.
3059 * error.h: prototype for scm_error_callback.
3061 * __scm.h: define lgh_error.
3062 (SCM_SYSERROR): redefine using lgh_error.
3064 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
3066 * error.c (scm_error): new procedure.
3068 * error.h: prototype for scm_error.
3070 * Makefile.in (install): install scmconfig.h from the current
3071 directory, not $(srcdir).
3073 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3075 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3076 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3077 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
3078 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
3079 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
3080 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
3081 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
3082 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
3083 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3084 vports.h, weaks.h: #include "libguile/__scm.h", not
3085 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
3086 dependencies are within libguile properly.
3088 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3090 * Makefile.in (.c.x): Simplify; there's no need to run this rule
3091 when scmconfig.h doesn't exist.
3093 * load.c (scm_sys_try_load): Correct spelling.
3095 * feature.c (scm_loc_features): Make this static.
3097 * Makefile.in (libpath.h): Omit trailing slash from path. We
3098 shouldn't require it of users, so why put it here?
3100 Move code to initialize and search %load-path from ice-9 to C
3101 code, so we can use the load-path to find the ice-9 boot code;
3102 this makes it easier to run Guile without installing it. See
3103 corresponding changes in guile/Makefile.in.
3104 * feature.c: Move stuff concerned with the load path to load.c.
3105 (scm_compiled_library_path): Deleted.
3106 Don't #include libpath.h here.
3107 * feature.h: Don't mention scm_compiled_library_path.
3108 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
3109 <sys/stat.h>, and <unistd.h> (if present).
3110 (R_OK): #define if the system hasn't deigned to.
3111 (scm_loc_load_path): New variable.
3112 (scm_init_load_path, scm_sys_search_load_path,
3113 scm_sys_try_load_path): New functions.
3114 (scm_init_load): Initialize scm_loc_load_path to point to the
3115 value cell of the Scheme %load-path variable.
3116 * load.h: Add declarations for scm_sys_search_load_path,
3117 scm_sys_try_load_path.
3118 * init.c: Call scm_init_load_path.
3119 * Makefile.in (feature.o, load.o): Dependencies updated.
3121 * load.c, load.h: Rewrite using PROTO macro.
3123 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3125 * gc.c (scm_cellp): New function: C predicate to determine if an
3126 SCM value can be regarded as a pointer to a cell on the heap.
3128 * gc.h: Added declaration of scm_cellp.
3130 * gdb_interface.h: New file: The GDB interface header from the GDB
3133 * gdbint.c: New file: GDB interface.
3135 * gdbint.h: New file: GDB interface.
3137 * libguile.h: Added #include <libguile/gdbint.h>.
3139 * init.c (scm_boot_guile): Added scm_init_gdbint.
3141 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
3142 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
3143 found if object files and source are kept separate).
3145 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
3147 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
3149 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
3151 * configure.in: Don't substitute the values of TCL_SRC_DIR and
3152 TK_SRC_DIR; they're not relevant any more.
3154 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
3155 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
3157 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
3159 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
3160 search path, so we can find the <libguile/MUMBLE.h> headers.
3162 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
3164 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
3165 implicit in the .c.o rule.
3166 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
3169 Put the library path in a header file, instead of passing it on
3170 the command line in every compilation.
3171 * Makefile.in (libpath.h): New target.
3172 (feature.o): Depend on libpath.h.
3173 (clean): Delete libpath.h.
3174 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
3175 * feature.c: ... #include "libpath.h" here.
3176 * .cvsignore: Ignore libpath.h.
3178 Don't install the unwashed masses of Guile header files in the
3179 main #include path; put most of them in a subdirectory called
3180 'libguile'. This avoids naming conflicts between Guile header
3181 files and system header files (of which there were a few).
3182 * Makefile.in (pkgincludedir): Deleted.
3183 (innerincludedir): New variable; this and $(includedir) are enough.
3184 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
3185 (installed_h_files): Divide this up. Now this variable lists
3186 those header files which should go into $(includedir) (i.e. appear
3187 directly in the #include path), and ...
3188 (inner_h_files): ... this new variable says which files appear in
3189 a subdirectory, and are referred to as <libguile/mumble.h>.
3190 (h_files): List them both.
3191 (install): Create innerincludedir, not pkgincludedir. Put
3192 the installed_h_files and inner_h_files in their proper places.
3193 (uninstall): Corresponding changes.
3194 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3195 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3196 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
3197 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
3198 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
3199 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
3200 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
3201 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
3202 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3203 vports.h, weaks.h: Find __scm.h in its new location.
3204 * __scm.h: Find scmconfig.h and tags.h in their new locations
3205 (they're both "inner" files).
3207 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
3209 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
3211 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3213 * posix.c: Doc fixes.
3215 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
3217 * socket.c: Don't include a prototype for inet_aton; just use a
3218 K&R style declaration, to avoid warnings but minimize the chance
3219 of conflicts with the system.
3221 On NextStep, <utime.h> doesn't define struct utime, unless we
3222 #define _POSIX_SOURCE before #including it.
3223 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
3224 * acconfig.h: New comment text for above CPP symbol.
3225 * configure.in: Call it.
3226 * posix.c: #define _POSIX_SOURCE if it seems necessary.
3228 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
3230 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
3231 testing for __EMX__.
3233 * posix.c: #include <libc.h>, if it exists.
3235 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
3236 don't even know if the latter exists.
3238 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
3239 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
3240 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
3242 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
3244 (scm_init_posix): Use them when initializing the Scheme constants
3247 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3249 * Makefile.in (libdir, includedir, bindir): Use the
3250 autoconf-supplied values, instead of deriving them ourselves.
3251 (pkgincludedir, datadir, pkgdatadir): New variables.
3252 (install, uninstall): Put the header files in a special
3253 subdirectory, not in the main search path.
3255 * Makefile.in (ALL_CFLAGS): Provide the proper value for
3256 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
3258 * Makefile.in (IMPLPATH): Deleted; never used.
3260 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
3261 on the Tcl/Tk source any more.
3262 (INCLUDE_CFLAGS): Remove references to the above.
3264 * Makefile.in (version.o): Corrected dependencies.
3266 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
3268 * libguile.h: #include "version.h"
3270 * init.c (scm_boot_guile): Call scm_init_version.
3271 * gscm.c (gscm_run_scm): Call scm_init_version.
3273 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
3274 GUILE_VERSION): AC_DEFINE these.
3275 (acconfig.h): #undef the above symbols.
3277 * Makefile.in (libobjs): Add version.o.
3278 (installed_h_files): Add version.h.
3279 (c_files): Add version.c.
3280 (gen_c_files): Add version.x.
3281 (version.o): New rule.
3282 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
3283 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

3291 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
3292 weaks.o): Add version.h to dependency lists.
3293 (markers.o): Remove duplicate rule.
3295 * version.h: New file.
3297 * version.c: New file.
3299 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3301 * symbols.c (scm_strhash): scm_downcase is now a function, not an
3302 array; use it appropriately. Since GCC is quite happy to
3303 subscript functions, it never warned us about this; we should use
3304 -Wpointer-arith in the future. I guess we never tested
3307 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3309 * socket.c: Doc and copyright fixes.
3311 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3313 * debug.c: Fixed and improved gdb support.
3315 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3317 * socket.c: Added declaration of inet_aton to avoid compiler
3318 warning. (Hope this solution is correct.)
3320 * stime.c: Added declaration of ftime. (This is missing in
3323 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
3325 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3327 * Makefile.in (c_files): add strerror.c.
3329 * strerror.c: new file from Emacs' sysdep.c.
3330 maybe configure should also check for sys_errlist.
3332 * configure.in (AC_REPLACE_FUNCS): add strerror.
3334 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3336 * debug.c (scm_init_debug): Added initialization for
3337 scm_evaluator_traps.
3339 * debug.h, debug.c: Various name changes.
3340 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
3341 "debug-options-interface". See commentary in options.c.
3343 * options.h, options.c: Options now have documentation strings.
3344 Also added a long explanatory commentary.
3346 * eval.c, print.h, print.c, read.h, read.c: Modifications to
3349 * gscm.c, init.c, root.c, throw.c: Bug fixes:
3350 last_debug_info_frame is now updated in all cases.
3352 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
3355 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3357 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
3358 Added option STACK_CHECKING.
3360 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3362 * Makefile.in: Added {debug,options,srcprop}.{h,c}
3364 * __scm.h: Removed symbols for debugging support.
3366 * acconfig.h: Added symbols for debugging support.
3368 * configure.in: Added user option for debugging support.
3369 --enable-debug will include the debugging code into libguile.a.
3371 * continuations.c (scm_make_cont): Enlarged the #if 0 around
3372 scm_relocate_chunk_to_heap.
3374 * debug.c: New file: low-level debugging support. It also
3375 includes support for debugging with gdb. (The extensions to gdb
3376 are written by Per Bothner at Cygnus.)
3378 * debug.h: New file: low-level debugging support.
3380 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
3381 argument pairs. Extensive modifications to the debugging
3382 evaluator. Added "SECTION:" commentaries to clarify what happens
3383 when, during double compilation. Renamed EVALIMP --> EVALIM.
3384 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
3385 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
3386 the beginning of the file. New procedure: scm_unmemocopy.
3387 Added some global state variables needed by the debugging
3388 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
3389 check_entry, check_apply, check_exit, debug_options and
3390 evaluator_traps. New acro: undefine.
3392 * eval.h: Renamed EVAL --> XEVAL.
3394 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
3395 --> scm_make_weak_key_hash_table.
3397 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
3398 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
3400 * libguile.h: Conditionally include debug.h
3402 * objprop.c (scm_object_properties, scm_set_object_properties_x):
3403 scm_object_properties shouldn't return handle. `handle' now gets
3404 initialized in scm_set_object_properties_x. scm_object_properties
3405 doesn't any longer create an entry in scm_object_whash.
3407 * options.c: New file: handling of run time options.
3409 * options.h: New file: handling of run time options.
3411 * posix.c (scm_getpgrp): Cast pointer to getpgrp.

3432 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3434 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
3436 * libguile.h: #include "objprop.h"; I guess this was forgotten.
3438 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
3439 and should be called by the final client.
3441 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
3443 * gc.h: Use the PROTO macro when declaring functions.
3444 * gc.c: Use the PROTO macro when declaring static functions.
3445 Remove the CPP hair around function definitions.
3447 * gc.c (scm_init_storage): Initialize scm_asyncs.
3449 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
3450 preprocessor symbol; "__scm.h" is where it might get #defined.
3451 * __scm.h: Similar: #include <scmconfig.h> before testing
3454 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
3456 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
3458 * init.c (scm_boot_guile): Add init_func argument; call
3459 (*init_func) instead of calling scm_appinit; it's ucky to
3460 hard-code names for the user's procedures.
3461 * init.h (scm_boot_guile): Adjust declaration.
3463 * __scm.h (PROTO): New macro, for declaring functions with
3466 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
3467 eliminate all the __STDC__ conditionals.
3468 (scm_boot_guile): Add declaration.
3469 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
3470 Remove __STDC__ conditionals around function definitions; the
3471 declarations in init.h will provide the same information, more
3474 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
3475 complain about it in the error message; the error message is
3476 adequate without that note, and there's nothing the user can do
3479 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
3481 * Makefile.in (ancillary): Drop def.sed.
3483 * posix.c (scm_init_posix): Use numeric values, rather than
3484 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
3485 F_OK. The symbols aren't available on some systems, and I'm
3486 pretty sure their values are fixed by common widespread practice.
3487 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
3489 More functions unavailable on some systems.
3490 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
3491 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
3493 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3494 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
3495 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
3496 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
3497 stub that signals an error as the #else.
3499 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
3501 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
3503 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
3505 * unif.c: include ramap.h.

3511 * ports.c: include sys/ioctl.h.
3513 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
3515 * configure.in: check for sys/ioctl.h.
3517 * ports.c: include <malloc.h> not "malloc.h".
3519 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3521 * fports.c: remove ttyname and tmpnam declarations.
3523 * posix.c: fewer ttyname declarations.
3525 * fports.c: include <string.h> not "string.h".

3532 genio.c, simpos.c, vports.c: include string.h.
3534 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
3536 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
3538 (scm_addr_buffer_size): change type from scm_sizet to int.
3539 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
3540 from scm_sizet to int.
3542 * error.c: include unistd.h.
3544 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
3547 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
3549 * __scm.hd, def.sed: deleted.
3551 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
3553 Changes for NeXT, suggested by Robert Brown.
3554 * configure.in: Call AC_TYPE_MODE_T.
3555 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
3556 NeXT. Put header file list in alphabetical order.
3557 * configure, scmconfig.h.in: Regenerated.
3558 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
3560 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
3563 * acconfig.h: New file, providing documentation for the CPP
3564 symbols defined in configure.in
3565 * acconfig-1.5.h: Removed; superceded by the above.
3567 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
3569 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
3571 * fports.c (scm_open_file): don't return #f, throw error.
3573 * ioext.c (fileno): renamed from %fileno.
3574 (soft-fileno): deleted.
3576 * ports.c (scm_port_revealed): don't need to check for -1 from
3578 (scm_set_port_revealed_x): return unspecified, not #f.
3580 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
3582 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
3584 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
3586 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
3588 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3590 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
3591 This is necessary on Ultrix, and doesn't hurt portability.
3593 * Makefile.in (dist-dir): New target, implementing a new dist system.
3594 (installed_h_files): Put in alphabetical order.
3595 Remove duplicate entries for markers.h and unif.h.
3596 (c_files): Remove duplicate entries for markers.c.
3597 (ancillary): Renamed from anillery; all uses changed. Remove
3598 PLUGIN; it's a directory, and needs special treatment in dist-dir.
3599 Remove all the ../doc/* files; doc/Makefile.in handles that.
3601 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3603 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3604 every if must have an else, or else the whole command has a
3605 non-zero exit code whenever the if's condition is false.
3607 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
3609 * posix.c: include string.h.
3611 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3613 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
3616 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
3617 Remove leading % from scheme names.
3618 Do not return error values, call SCM_SYSERROR or similar.
3620 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
3622 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
3624 * struct.c (scm_init_struct): new file.
3626 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
3628 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
3629 (scm_list_head): added list-head for rapidly chopping argument
3630 lists off of longer lists (and similar).

3635 handle for obj, not the handle itself.
3637 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
3639 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
3640 weak hash tables last of all marking to avoid an obscure gc bug.
3641 WARNING: circular lists stored in a weak hash table will hose us.
3643 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
3645 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
3646 new functions similar to scm_substring_move_left_x and
3647 scm_substring_move_right_x.
3649 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
3651 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
3654 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
3656 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
3658 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
3660 * strports.c (scm_strprint_obj): convenience function. C for
3661 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
3663 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
3664 removed to a separate library
3666 * init.c (scm_boot_guile): copied from guile-tcl.c.
3667 Initialization specific to tcl interpreters removed.
3669 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
3671 * ports.c (scm_ports_prehistory): size malloced here doesn't
3672 matter so long as it is non-0 (got rid of "* 4").
3674 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3676 * gscm.h: gscm_mkarray eliminated (presumably was not being used
3677 since its definition was bogus).
3679 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
3681 * mallocs.[ch]: back again (for rx at least).
3683 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
3685 * ports.c: removed functions relating to the mapping between ports
3686 and descriptors. (That stuff is unix-specific and should be collected
3687 in a separate library).
3689 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
3690 (Tom Mckay@avanticorp.com)
3692 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
3694 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3695 handled correctly (SCM_FREEP was applied to them) -- test for
3696 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
3697 being overwritten with #f. (brown@grettir.bibliotech.com)
3699 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>

3728 * procprop.c (scm_stand_in_scm_proc):
3729 NOTE: don't use a alist here.
3730 (scm_set_procedure_properties_x): fix type checking throughout this file.
3732 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
3734 * ports.c (scm_remove_from_port_table): adjust scm_mallocated

3740 * vports.c (scm_make_soft_port): allocate a port table entry
3741 (possibly triggering gc) before setting the tag of the corresponding
3744 * pairs.c (scm_delq_x): never throw an error.
3746 * vectors.c (scm_make_vector): made the default vector fill argument
3747 into '() (much more useful than the previous value, "#unspecified")
3749 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
3751 * ports.c (scm_add_to_port_table): Added fields
3752 to port table entries: file_name, line_num, col.
3753 Update these in open_file, gen_getc and gen_ungetc.
3754 Added procedures to access those fields.
3756 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
3758 * procs.c (scm_make_subr_opt): new entry point for making
3761 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
3763 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
3765 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
3767 * numbers.c (scm_exact_p): This function no longer
3768 implements "integer?".
3770 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
3772 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
3773 (scm_gc_stats): return an assoc of useful data. Replaces "room"
3774 and the stats reporting formerlly built into repl.
3776 * repl.[ch]: removed.
3777 GC statistics keeping moved to gc.c.
3778 Other statistics keeping can be done from Scheme.
3779 REPLS are now written in Scheme.

3786 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
3788 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
3790 * feature.c (scm_compiled_library_path): moved here from repl.c.
3791 This file is for stuff relating specifically to Scheme libraries
3794 * eval.c (scm_m_define): don't give warning about redefinition, don't
3797 NOTE: this should throw a resumable exception with parameters --
3798 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
3800 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.

3822 because it changes size.
3824 (stputc stwrite): check/change the strings length with interrupts
3827 * objprop.c (scm_set_object_property_x &c): use the generic
3828 hashing functions and be threadsafe.

3831 (per suggestion jaffer@gnu.ai.mit.edu).
3833 * mbstrings.c (scm_multi_byte_string): guard against argument list
3836 * strings.c (scm_make_string): loop cleanup

3890 set the multi_byte flag correctly in symbols. This is wrong.
3891 intern_obbary_soft and msymbolize should take an extra parameter.
3892 Also, weird multibyte symbols don't print correctly.
