1 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3 * eval.c: Include scmconfig.h at the beginning of the file so that
4 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
7 * regex-posix.c: #include "_scm.h" before conditionally #including
8 <regex.h>; the former defines HAVE_REGCOMP.
10 * regex-posix.c: #include <regex.h> conditionally, so the file is
11 CPP'able (for dependency scanning) even on systems that don't have
14 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
16 Add new R4RS-compliant syntax for keywords.
17 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
18 regardless of the setting of the `keywords' read option.
19 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
20 can be re-read no matter what the setting of the `keywords' read
23 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
25 Add support for POSIX regular expressions.
27 * regex-posix.c, regex-posix.h: New files. (Some code
28 is taken liberally from rx/rgx.c in the old Guile dist.)
30 * init.c: Include regex-posix.h.
31 (scm_boot_guile_1): Call scm_init_regex_posix.
33 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
34 Add regex-posix.[ch] sources.
35 * Makefile.in: Regenerated.
37 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
38 to do this automatically? It didn't for me, bleh.)
40 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
42 * fports.c (print_pipe_port): New function.
43 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
44 latter doesn't even take the right arguments.
46 * Makefile.am: Increment shared lib revision number. I think
47 sometimes the uninstalled Guile finds the installed shared lib;
48 Gord says doing this might help. As things turned out, I can't
50 * Makefile.in: Regenerated.
52 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
53 passing it as the closure argument to scm_boot_guile. (Bill
56 * ports.c (print_void_port, putc_void_port, puts_void_port,
57 write_void_port, flush_void_port, getc_void_port, close_void_port,
58 noop0): Use ANSI prototypes instead of K&R declarations, so the
59 initialization of void_port_ptob gets aggressively type-checked.
60 Fix arguments of print_void_port and write_void_port. (Bill

94 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
96 * script.c (scm_find_executable): Use prototype-style definition
97 here; apparently it's not quite right to have const in a prototype
98 and then use a K&R declaration. I wonder if stuff like this will
99 go away if we compile with -Wrequire-prototypes, or whatever that
100 is... (Bernard URBAN)
102 * scmhob.h: New text from Bernard URBAN.
104 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
106 * script.c: Don't #define const on hpux. Configure takes care of
107 this. (Thanks to Larry Schwimmer.)
109 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
110 decide whether to #include <unistd.h>, instead of listing a bunch
111 of systems. Don't #include stdio twice. Removed dyked-out
112 definition of scm_find_impl_file.
114 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
116 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
117 library version info to 1:0.
118 * Makefile.in: Regenerated.

124 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
125 throw.c: Update copyright years; these files have been worked on
126 significantly in 1997, but only had copyright years for 1996.
127 Also, change name of copyright holder on some from Mikael
128 Djurfeldt to Free Software Foundation; he has signed papers
129 assigning the changes to the FSF.
131 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
132 reason not to give the user the option.
134 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
135 Return #f on end-of-file when scanning table (i.e. when called
136 with no arguments). Try to catch errors, when we can.
137 * posix.c (scm_getgrgid, scm_getpwuid): Same.
139 * script.h (scm_shell_usage, scm_compile_shell_switches): New
140 external declarations. These are useful.
142 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
144 * posix.c: don't include <sys/select.h> or define macros for
145 select, since they were not used in this file.
147 * filesys.c (scm_select): make the fifth parameter microseconds,
148 not milliseconds. let the fourth parameter be either a real value
149 or an integer or #f. The first, second and third arguments can
150 now be vectors: the type of the corresponding return set will be
152 (set_element, get_element): new static procedures.
154 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
156 * strports.c (scm_eval_string): New function.
157 (scm_eval_0str): Trivially re-implemented in terms of
159 * strports.h (scm_eval_string): New extern decl.
161 * net_db.c (h_errno): Add extern decl for this.
163 * fports.c (local_pclose): New function.
164 (scm_pipob): Use it in the initializer here.
167 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
168 Use a meaningful error message when signalling an error. For
169 this, scm_gethost must check h_errno rather than errno.
171 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
173 * Makefile.in: Regenerated, using automake-1.1p.
175 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
177 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
180 * script.c (scm_compile_shell_switches): don't append (quit) if
182 (scm_shell): call scm_exit_status and exit on the result of the
185 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
187 Ensure that shared substrings are handled properly when passed to
188 a system call or other foreign function. Many thanks to Tim
190 * symbols.h (SCM_COERCE_SUBSTR): new macro.
191 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
192 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
193 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

195 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
196 (scm_display_error_message): use RO macros when strings may be RO.
197 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
198 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
199 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

203 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
204 scm_strftime), vports.c (scm_make_soft_port): use
205 SCM_COERCE_SUBSTR to make sure shared substrings are
208 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
210 * error.c (scm_error): Add newline to error message.
212 * init.c (scm_init_standard_ports): Doc fix.
214 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
216 * dynl-shl.c: Completely replaced with new code from Bernard
219 * script.c (scm_ice_9_already_loaded): New variable.
220 (scm_compile_shell_switches): Use it.
222 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
224 * filesys.c (scm_input_waiting_p): add missing third argument to
227 * stime.c (scm_localtime): copy the result of localtime before
228 calling gmtime in case they share a buffer.
229 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
232 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
234 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
236 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
238 * Makefile.am (check-local): New target, which causes 'make check'
239 to run gh_test_c and gh_test_repl, with some trivial input.
240 * Makefile.in: Rgnrtd.
242 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
244 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
247 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
249 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
250 sure how this was supposed to work.
251 (scm_async_click): don't send SCM_TICK_SIGNAL.
252 (scm_init_async): don't initialize %tick-thunk.
254 * the following change doesn't affect the Scheme interface:
255 gc-thunk is called at the end of garbage collection. however it's
256 no longer implemented by pretending it's a signal.
258 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
259 system async corresponding to scm_gc_thunk.
260 * async.h: declare scm_gc_async.
261 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
262 gc-thunk directly, instead of going through a signal handler.
263 (scm_gc_async): new variable, points to the GC system-async.
264 (scm_init_async): save the GC async as scm_gc_async instead
265 of using system_signal_asyncs.
266 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
268 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
270 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
271 Don't screw up if we're interrupted.
272 * Makefile.in: Regeneradet.
274 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
276 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
278 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
279 we're not using AM_INIT_GUILE_MODULE any more.
280 * Makefile.in: Reneregated.
282 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
284 Functions for finding variable bindings, grace à Tim Pierce.
285 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
286 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
288 Get 'make dist' to work again.
289 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
290 * Makefile.in: Regenerated, like a surry without a fringe on top.
292 Changes for reduced Guile distribution: one configure script,
294 * configure.in, configure: Removed.
295 * acconfig.h, acinclude.m4: Moved to parent directory, where the
296 real configure script lives.
297 * Makefile.in, scmconfig.h.in: Regenerated.
299 * init.c: #include "script.h", to get prototype for script.c's
302 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
304 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
305 scm_must_malloc, not raw malloc.
307 * script.c (scm_compile_shell_switches): Dyke out debugging output
310 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
312 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
314 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
315 system has them. Hope this is safe. Previously
316 sys/timeb.h was included if HAVE_FTIME was defined or if
317 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
318 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
320 * ioext.c (scm_setfileno): add missing third argument to
323 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
325 * eq.c (scm_equal_p): Correctly compare strings of different
326 varieties. (Thanks to Tim Pierce.)
328 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
330 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
331 #! block comment must occur on a line all by itself.
333 Move most of the guts of shell command processing into libguile,
334 so guile.c can be very small (and eventuallly auto-generated. (I
335 mean, generated mechanically, not self-generated. Hmm.))
336 * guile.c, script.c, script.h: New source files.
337 * init.c (scm_boot_guile_1): Call scm_init_script.
338 * libguile.h: #include "script.h".
339 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
340 targets, for new executable.
341 (libguile_la_SOURCES): Mention script.c.
342 (modinclude_HEADERS): Add script.h.
343 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
344 not dynamic linking is enabled. This is because we're generating
345 executables now. Move CY_AC_WITH_THREADS call after those, so the
346 values of cy_cv_threads_libs captures the libs chosen above.
347 * Makefile.in, configure, aclocal.m4: Regenerated.
349 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
350 We don't maintain this interface any more, and it just confuses
353 * alloca.c: #include <scmconfig.h>, not <config.h>.
354 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
355 it'll get included in disties.
357 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
359 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
360 be distributed, because they confuse people.
361 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
363 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
365 * configure.in: check for presence of gethostent (not present on
367 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
368 * configure, scmconfig.h.in: Regenerated.
370 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
372 * backtrace.c (scm_backtrace): Split message string across
373 newlines properly. GCC is more tolerant of this than other
376 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
378 Merge threads directory into libguile.
379 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
380 threads.h: New source files.
381 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
382 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
384 (modinclude_HEADERS): Add threads.h, coop-defs.h.
385 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
386 coop-threads.c.cygnus, coop-threads.h.cygnus.
387 * configure.in: If we're using threads, include threads.o in
389 * _scm.h, libguile.h: threads.h lives in this directory now.
390 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
391 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
392 currently used, but brought along for information's sake.
393 * ChangeLog-threads: log from old 'threads' directory.
394 * Makefile.in, configure: Rebuilt.
396 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
398 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
401 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
403 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
405 Merge GH interface library into libguile.
406 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
407 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
408 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
409 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
411 (EXTRA_libguile_la_SOURCES): ... here.
412 (pkginclude_HEADERS): Add variable, to get gh.h installed.
413 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
414 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
415 New variables, describing how to build the gh test programs.
416 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
417 build the test programs, and we probably should have been linking
418 libguile.la against them all along, to support AIX shared libs.
419 Add cflags for threads to CFLAGS; add libs for threads to new
420 variable THREAD_LIBS, used in Makefile.am.
421 * ChangeLog-gh: log from old `gh' subdirectory.
422 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
424 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
426 * acconfig.h: Undo change of Apr 9; including the definition of
427 PACKAGE in the guile headers conflicts with applications' own
429 * scmconfig.h.in: Regenerated.
431 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
433 * filesys.c (scm_fcntl): New function from Roland McGrath.
434 (scm_init_filesys): New symbols for use with fcntl.
435 * filesys.h: Added prototype.
437 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
438 when PROC is receiving no arguments.
440 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
442 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
443 have S_IFSOCK. This is the case under Ultrix.
445 * posix.c (scm_status_exit_val, scm_status_exit_val,
446 scm_status_term_sig, scm_status_stop_sig): Modified to work with
447 Ultrix versions of WIFSTOPPED, etc., which assume that their
448 arguments are lvalues (hmm).
450 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
454 * throw.c: Doc fixes; rearranged.
456 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
458 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
460 * acconfig.h: Added entry for PACKAGE.
461 * scmconfig.h.in: Regenerated.
463 Changes to work with automake-1.1n, which has better libtool support.
464 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
465 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
467 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
469 * Makefile.in: Rebuild.
471 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
473 * stime.c (scm_mktime): take an optional zone argument.
474 (scm_localtime): check putenv return value.
475 (scm_strftime, scm_strptime): moved from posix.c. move #include
477 stime.h, posix.h: update prototypes.
478 (bdtime2c, setzone, restorezone): new static procedures.
479 (scm_mktime, scm_strftime): use them.
480 (scm_strftime): don't call mktime before strftime. Use
481 filltime for return value.
482 (filltime): convert NULL zname to #f.
483 (scm_strptime): return a count of characters consumed, not
484 the remaining string.
486 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
488 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
489 (scm_mktime): likewise.
491 Uncomment localtime and mktime.
493 * configure.in: add AC_STRUCT_TIMEZONE.
495 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
497 * stime.c (scm_init_stime): don't define ticks/sec.
498 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
499 return value problem and is still portable.)
501 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
503 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
504 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
505 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
506 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
507 cpp_err_symbols.c): Corresponding changes.
508 * Makefile.in: Regenerated.
510 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
512 * posix.c (scm_putenv): don't check HAVE_PUTENV.
513 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
514 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
515 * putenv.c: new file, from sh-utils 1.12.
517 * posix.c (scm_environ): use malloc in place of scm_must_malloc
518 since allocation isn't for Scheme objects.
519 (scm_putenv): copy strings before placing in the environment.
521 * stime.c (scm_current_time): throw an error if time returns -1,
522 instead of returning #f.
523 (scm_get_internal_real_time, scm_get_internal_real_time): use
524 scm_long2num for return value instead of SCM_MAKINUM.
526 * stime.h: prototypes updated.
528 * stime.c (scm_time_in_msec): apparently unused, deleted.
530 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
532 * configure.in: check for gettimeofday.
534 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
535 which may be more usefully portable than a gettimeofday interface.
537 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
539 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
541 * Makefile.in: Regenerated.
543 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
545 * stime.c (filltime): recovered static procedure.
546 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
549 * posix.h: add prototype for scm_close_pipe, remove prototypes for
550 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
552 * posix.c (scm_mknod): split the mode argument into type and perms
553 arguments, like the extra fields returned by stat.
555 * fports.c (scm_pipob): set the close, free and print procedures.
556 (scm_close_pipe): new procedure.
558 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
559 define them in boot-9.scm
561 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
563 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
564 wan't defined. Don't include fd.h.
566 * Previously fd.h was regenerated whenever configure was run,
567 forcing a couple of files to be recompiled.
569 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
570 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
571 Check for _fileno as well as _file.
573 * ioext.c: don't fd.h.
574 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
577 * Change the stratigy for getting information about errno
578 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
579 generating lists of symbols during the build process, which will
580 not always work, include comprehensive lists in the distribution.
581 To help keep the lists up to date, the "check_signals" and
582 "check_errnos" make targets can be used.
584 * configure.in: don't check for a command to extract errno codes.
585 * Makefile.am: update file lists, remove errnos.list and errnos.c
586 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
587 check_errnos targets.
588 (CLEANFILES): remove errnos.c and errnos.list, add
589 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
590 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
591 * errnos.default: deleted.
592 * cpp_signal.c: new file.
593 * cpp_errno.c: renamed from errnos_get.c.
594 * cpp_err_symbols, cpp_sig_symbols: new files.
595 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
596 * error.c (scm_init_error): #include cpp_err_symbols instead of
598 * posix.c (scm_init_posix): don't intern signal symbols. #include
601 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
603 * strop.c (scm_i_index): allow the lower bound to be equal to the
604 length of the string, so a null string doesn't always give an error.
606 * posix.h: new prototypes.
607 * posix.c (scm_status_exit_val, scm_status_term_sig,
608 scm_status_stop_sig): new functions, as in scsh. They break down
609 process status values as returned by waitpid.
611 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
613 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
614 configure doesn't know about it.
616 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
618 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
620 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
621 which defines C variables with global linkage.
623 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
625 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
628 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
630 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
631 has time to check why this doesn't work well with continuations.
633 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
635 * Fix shell syntax error; some shells won't tolerate
636 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
638 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
640 * posix.c (scm_uname): throw an error if uname fails instead
643 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
645 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
648 * async.c (scm_ints_disabled): definition moved from error.c.
650 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
652 * acconfig.h: Removed PACKAGE.
654 * scmconfig.h.in: Regenerated.
656 * snarf.h: g++ says it's non-portable not to specify the first
657 argument in a varargs declaration. I introduced the first
658 argument by using preprocessor conditionals.
660 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
662 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
663 (scm_freopen): use RO string macros for filename and modes.
664 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
666 * posix.c (scm_getgrgid): simplify conversion of name to C string.
667 (scm_mknod): use RO string macros for path.
669 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
670 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
672 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
673 use SCM_ROSTRINGP and SCM_ROCHARS.
675 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
677 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
680 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
681 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
682 support for byte vectors.
684 * print.c (scm_iprin1): Limit number of vector elements printed
685 according to pstate->length.
687 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
689 * backtrace.c (scm_display_error_message): don't segv if message
692 * error.h: prototype for scm_error_scm.
694 * error.c (scm_error_scm): new procedure, reimplements scm-error
695 in C and uses scm_error.
697 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
699 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
700 pointer to the Scheme variable read-hash-procedures and intern it
701 in scm_init_read. Modify scm_read_hash_extend and
702 scm_get_hash_procedure to use the pointer.
704 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
706 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
707 (SCM_KEYWORD_STYLE): defined.
709 * read.c (scm_read_opts): add a keywords option. This isn't a
710 boolean option, in case someone wants to add support for DSSSL
712 Setup scm_keyword_prefix symbol.
713 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
715 I've left keyword support disabled by default, since it doesn't
716 seem to break the module system and it gives R4RS standard behaviour.
717 It can be reactivated with (read-set! keywords 'prefix).
719 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
721 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
722 before constructing arbiter.
724 * eval.c (scm_m_define): Bugfix: Check that the object is a
725 closure before setting the procedure property!
727 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
729 * ports.c: Removed `ungetc-char-ready?'.
731 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
733 * read.c (scm_init_read): intitialise scm_read_hash_procedures
734 (idea from Mikael: make it a pair so scm_permanent object only
736 (scm_read_hash_extend): don't call scm_permanent_object.
737 (ideas from Mikael): if chr is already in the list, replace its
738 procedure instead of appending it again. If proc is #f, remove
740 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
742 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
744 * gdbint.c (gdb_read): update scm_lreadr usage.
746 * load.h: update prototypes.
748 * load.c (scm_primitive_load, scm_read_and_eval_x,
749 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
751 * read.h: add prototype for scm_read_hash_extend. Change args for
754 * read.c (scm_read_hash_procedures): new variable.
755 (scm_read_hash_extend): new procedure.
756 (scm_get_hash_procedure): new procedure.
757 (scm_lreadr): use scm_get_hash_procedure instead of an argument
758 for extended # processing.
759 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
760 scm_read_token): remove case_i, sharp arguments. Change callers.
762 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
764 * read.h (SCM_N_READ_OPTIONS): increase to 3.
765 (SCM_CASE_INSENSITIVE_P): define.
767 * read.c: add case-insensitive option to scm_read_opts.
768 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
769 to determine whether to convert symbol case.
770 (default_case_i): definition removed.
771 * read.c (scm_read_token): if case_i, downcase ic before doing
774 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
776 * configure.in: Added configuration option `guile-debug'.
777 Configure with --enable-guile-debug if you want a bunch of extra
778 functions used for debugging when developing Guile.
780 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
782 * procs.c (make-cclo): New undocumented debugging procedure: Make
783 compiled closure with internal procedure PROC and length LENGTH.
784 Only compiled if GUILE_DEBUG is defined.
786 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
788 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
790 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
792 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
793 with 3 or more args internally to the evaluator.
795 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
797 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
798 with 3 or more args internally to the evaluator. This is mainly
799 because we don't want to pass entry and exit points of the
800 debug support twice, but it also seems to increase the speed of
801 the evaluator for such calls (e. g. (+ 1 2 3)).
803 * backtrace.c (scm_display_application): New procedure:
804 display-application; Set fancy printing parameters individually
805 for different types of display (backtrace, error, application).
806 (These should of course be customizable!)
808 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
809 clear the CHECK-flags.
811 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
813 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
815 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
817 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
818 from pairs with a GLOC in the car.
820 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
821 otherwise `symbol-hash' will behave badly.
822 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
823 we get segmentation fault!
825 * symbols.c: Added #include "weaks.h". New functions:
826 `builtin-bindings' and `builtin-weak-bindings'. (These will be
827 moved to an extraneous library when we split libguile.)
829 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
831 * filesys.c (scm_stat): stat now takes fport arguments too as
832 documented in the manual.
834 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
836 * debug.c (scm_single_step): Bugfix: Call continuation with
837 scm_call_continuation instead of throwing to it.
839 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
841 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
842 argument wasn't declared to be optional.
844 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
846 * stime.c (scm_init_stime): Add feature "current-time".
848 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
850 * throw.h: prototype for scm_exit_status.
851 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
852 args to derive an exit status. Allows (quit) to work from a
854 (scm_exit_status): new function.
857 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
859 * eval.c (scm_deval): Removed some old code.
860 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
862 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
865 * symbols.c (msymbolize): Bugfix: Must initialize property list to
868 * procs.c: Introduce the existent C function scm_thunk_p at the
869 Scheme level as well.
871 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
873 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
874 used from C to easily lookup the value of a symbol in the current
877 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
879 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
880 scm_init_unif in this file. This will also fix a previous problem
883 * configure.in: Added AM_MAINTAINER_MODE
885 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
887 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
890 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
892 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
893 source files that are not always included in libguile but should
894 have their dependencies calculated by automake. This variable is
895 recognized by automake, no further magic is needed.
896 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
897 to deal exclusively with *.lo files, as it seems. The *.o files
898 are built automatically when the corresponding *.lo file gets
901 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
903 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
906 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
908 * unif.c (scm_array_set_x): minor change to argument error checking.
910 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
912 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
913 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
914 They should only be included in the library at configure.in's
916 (libguile_la_LDADD): Include the appropriate .lo files here.
917 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
918 so we know when to build them (and their .lo bretheren).
919 * configure.in (LIBLOBJS): New substituted variable. We let
920 configure decide which .o files to include in LIBOBJS, and then
921 put the corresponding list of .lo files in LIBLOBJS. The latter
922 is what we pass to libtool.
923 * Makefile.in, configure: regenerated.
925 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
927 * symbols.c (scm_sysintern0): New function. Contains the core of
928 old scm_sysintern but doesn't take a second value argument.
929 (scm_sysintern): Now uses scm_sysintern0.
930 (scm_sysintern_no_module_lookup): Renamed to
931 scm_sysintern0_no_module_lookup and doesn't take a second value
934 * symbols.h (scm_sysintern0: Added declaration.
936 * options.c (scm_init_opts): Use scm_sysintern0 instead of
937 scm_sysintern when interning option keys. Otherwise we risk
938 destroying the values of already interned variables.
940 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
941 scheme-level boolean (use SCM_NFALSEP).
943 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
945 (scm_backtrace): New function. (C version of old function from
946 boot-9.scm) Motivation: Make it possible to display backtraces
947 without depending on boot-9.scm. (I'm uncertain if this
948 motivation is good enough...)
950 * root.h (scm_root_state): Add member the_last_stack_var.
951 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
953 * root.c (mark_root): Mark scm_the_last_stack_var.
955 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
958 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
960 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
961 1. mark_lazy_catch didn't mark the smob.
962 2. Both functions above have standard variants:
963 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
964 free_lazy_catch --> scm_free0.
966 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
968 * throw.c (scm_internal_lazy_catch): New function.
969 (scm_lazy_catch): Rewritten to use it.
970 (scm_ithrow): Handle the new lazy catch representation.
971 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
972 that doesn't have a jmpbuf is a lazy catch clause.
973 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
974 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
975 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
977 (scm_init_throw): Register the new lazy-catch smob type.
978 * throw.h (scm_internal_lazy_catch): decl for new function.
980 * throw.c (scm_internal_catch): Doc fixes.
982 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
983 configure.in. Including this might cause problems if applications
984 that link against libguile include their own copies of alloca, but
985 if they're using autoconf, they should be adding libguile to LIBS
986 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
987 the copy in libguile, and things will be okay. (I think.)
989 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
991 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
993 strop.h: move prototypes too.
995 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
997 * posix.c (scm_init_posix): don't intern EINTR since it's now done
1000 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
1001 etc. I deleted them from filesys.c long ago, but didn't
1002 notice they were here too (although ineffective since
1003 sys/stat.h wasn't included).
1005 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
1007 * eval.c: Don't define alloca in GCC case. gcc will automatically
1008 use __builtin_alloca if appropriate.
1010 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1012 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
1013 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
1014 that values of automatic variables are preserved. See comments
1015 for safe_setjmp for details.
1017 Change from Thomas Morgan:
1018 * variable.c: Include eq.h.
1019 (var_equal): New function.
1020 (variable_smob): Use var_equal as the discriminator for variables.
1022 * throw.c (s_throw): Remove extraneous declaration.
1024 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
1025 * eval.c: Add necessary CPP cruft to support that.
1026 * configure, Makefile.in, scmconfig.h.in: regenerated.
1028 Change from Thomas Morgan:
1029 * procprop.c (scm_procedure_properties): Convert the Scheme
1030 boolean returned by scm_procedure_p into a C boolean before using
1031 it as a condition for SCM_ASSERT.
1032 (scm_procedure_property): Likewise.
1034 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
1035 indications of Unixness.
1038 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
1040 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
1042 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
1044 * read.c (scm_lreadr): use scm_misc_error to improve one of the
1045 "unknown # object" error messages.
1047 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
1048 (scm_i_index) and declare it static. Add a 'direction' argument
1049 to indicate what way the search should go.
1050 (scm_i_index): throw out-of-range error instead of wrong-type-arg
1052 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
1053 strop.h: remove scm_i_index, scm_i_rindex prototypes.
1055 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1057 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
1059 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
1060 to avoid clash with various scsh forks.
1062 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
1064 The following two changes (ramap.c, throw.c) are motivated by the
1065 apparent unportability of forward declarations of static arrays of
1066 the form `static foo bar[];'.
1068 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
1069 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
1071 * throw.c (scm_throw): Moved above scm_ithrow.
1073 * options.h: Removed the extern declarations of scm_yes_sym and
1074 scm_no_sym since these are static.
1076 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1078 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
1080 * Makefile.am: remove AWK=@AWK@.
1081 Add a rule for generating errnos.list.
1082 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
1084 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
1085 don't extract errnos, just set a variable (avoids the
1086 need to recompile error.c just because configure is run.)
1088 * unif.h: update prototypes.
1089 * unif.c (scm_uniform_array_read,write): change the offset and
1090 length arguments to start and end, for consistency.
1092 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
1094 * ioext.h: update prototypes.
1095 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
1096 scm_read_line_x, it's a more general procedure using an
1097 interface from scsh. read-line and read-line! are now defined
1099 Note that the new read-line trims the terminator
1100 by default, previously it was appended to the returned string. An
1101 optional argument specifies how to process the terminator (scsh
1102 compatible). For the old behaviour: (read-line port 'concat).
1103 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
1104 returns a pair, but is converted to multiple values if the scsh
1107 socket.h: update prototypes.
1108 * socket.c (scm_recvfrom): for consistency with other procedures,
1109 take start and end as separate optional arguments.
1110 (scm_recv, scm_recvfrom): don't allow the second argument
1111 to be a size, only a buffer. Change the scheme names to
1112 recv! and recvfrom!. Don't return the buffer.
1114 * ioext.h, posix.h: move prototypes too.
1115 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
1116 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
1117 "read.h" and "unif.h".
1118 * ioext.c: include "chars.h"
1120 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
1122 * dynl.c: The dynamic linking and module registration functions
1123 are now defined even when dynamic linking is not available for the
1124 host system. Some of their functionality can be done without
1125 dynamic linking; when it's really needed, they throw errors.
1127 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
1129 * configure.in: Only define DYNAMIC_LINKING when one of the system
1130 dependent functions is detected.
1131 * dynl.c (scm_dynamic_func): New function to get the address of a
1132 function in a dynamic object.
1133 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
1134 produced by scm_dynamic_func as the thing to call.
1136 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
1138 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
1139 (scm_register_module_xxx, scm_registered_modules,
1140 scm_clear_registered_modules): New functions.
1142 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
1144 * symbols.c (scm_sysintern): Renamed to
1145 scm_sysintern_no_module_lookup.
1146 (scm_sysintern): New function to take the place of the old
1147 scm_sysintern. It uses the current toplevel lookup closure to give
1148 the symbol its value. This is a temporary hack to put packages
1149 like gtcltk into their own module.
1150 (scm_can_use_top_level_lookup_closure_var): New variable to tell
1151 us whether `scm_top_level_lookup_closure_var' has been initialized
1153 * eval.c (scm_init_eval): Set it.
1155 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
1157 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
1158 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
1160 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
1162 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
1163 scm_sys_dup): deleted: FD capability will be added to other
1165 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
1166 scm_fd_free, fd_smob, scm_intern_fd.
1167 (scm_open): renamed from scm_sys_open. Return a port instead of
1168 an FD object. Make the mode argument optional.
1169 (scm_sys_create): deleted, it's just a special case of open.
1170 (scm_init_filesys): move interning of constants O_CREAT etc.,
1171 here (were previously using SCM_CONST_LONG macro).
1172 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
1174 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
1175 include "fports.h" and <stdio.h>
1176 (scm_stat, scm_select): don't support FD objects.
1178 * error.h: adjust scm_syserror_msg prototype.
1179 * error.c (scm_syserror_msg): take an extra argument for errno.
1180 Using the global value didn't always work, since it could be
1181 reset by procedure calls in the message or args arguments.
1183 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
1184 I don't understand why the check was there (and what about the
1187 * strop.c (scm_string_copy): allow shared substrings to be copied.
1189 * unif.h: corresponding change to prototypes.
1190 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
1191 recognize two new optional arguments: offset and length. Allow
1192 the port argument to be an integer (file descriptor, for scsh).
1193 Include <unistd.h> for "read" prototype.
1195 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
1197 * socket.c: don't include filesys.h.
1199 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
1201 * Makefile.am: add AWK=@AWK@ (?)
1203 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
1205 Add a rule to generate errnos.c from errnos.
1206 * error.c (scm_init_error): include errnos.c.
1207 * errnos_cnvt.awk: new file, converts the list of errno codes to
1209 * errnos_get.c: new file.
1210 * errnos.default: new file, contains errnos to try if they can't
1211 be extracted from errno.h.
1212 * configure.in: if using GCC, try and extract errno codes from
1216 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
1218 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
1219 * Makefile.am: Made libguile into a libtool library.
1220 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
1221 Set libtool_libs to indicate that libguile is a libtool library.
1222 See guile/ChangeLog for details.
1223 * .cvsignore: ignore "*.lo", the libtool library objects.
1225 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1227 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
1228 use htons in getservbyport argument.
1230 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
1232 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
1233 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
1236 * objprop.c (scm_object_property): No need to take the CDR of the
1237 value returned by scm_object_properties, since Aug 20 change.
1239 * configure.in: When checking for struct linger, #include
1240 <sys/types.h> as well as <sys/socket.h>. I've never known
1241 <sys/types.h> to cause any portability problems, and Solaris's
1242 <sys/socket.h> needs it.
1243 * configure: Rebuilt.
1245 I think the Sun compiler has chosen a perverse way to interpret
1246 ANSI declarations combined with K&R definitions. We'll
1247 appease it a little bit. But when it invades France, we fight.
1248 * print.c (scm_iprlist): Change 'tlr' argument to an int.
1249 * print.h (scm_iprlist): Here too.
1250 * numbers.c (scm_divbigdig): Change definition to match
1251 declaration in numbers.h.
1252 * unif.c (scm_makflo): Change definition to match declaration in
1255 * init.c (scm_boot_guile): Don't return the value of
1256 scm_boot_guile_1. This function doesn't return a value;
1257 scm_boot_guile_1 doesn't return a value (or return at all).
1259 * eval.c (unmemocopy): Add a semicolon to appease the Sun
1262 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
1263 compile. I have a feeling this function is a bad idea anyway ---
1264 one should always test for features, not systems.
1266 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
1267 semicolons. Only pure luck kept this from being noticed earlier.
1269 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
1271 * socket.c (scm_recvfrom): Added missing semicolon.
1273 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1275 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
1276 the buffer and start and end positions for scsh networking
1279 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
1281 * configure.in: Revert previous change to this file; the problem
1282 is due to transient automake weirdness.
1283 * configure: Rebuilt.
1285 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
1286 PLUGIN/guile.libs. configure generates the latter from the former.
1287 * Makefile.in: Rebuilt.
1289 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
1290 need this if we install scripts, like guile-snarf.
1291 * configure: Rebuilt.
1293 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1295 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
1297 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
1299 * socket.c (scm_addr_vector): fix faulty scm_listify.
1301 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
1303 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
1304 style block comment is no longer considered an error.
1306 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
1308 * PLUGIN/guile.libs.in: New file.
1309 * PLUGIN/guile.libs: Removed from repository.
1310 * configure.in: Create PLUGIN/guile.libs from
1311 PLUGIN/guile.libs.in. This is for including additonal libraries
1312 needed for dynamic linking.
1313 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
1314 instead of PLUGIN/guile.libs.
1316 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
1318 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
1320 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
1321 occurrences of the given element from the list, not just the
1322 first. This is how the Emacs Lisp functions behave, how the
1323 analogous Common Lisp functions behave, and (I believe) how the
1324 older Maclisp functions worked. I realize that this change may
1325 break code, but it seemed better to break it before the Guile
1328 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
1329 Their prototypes were already present in gc.h, but they weren't
1331 (scm_init_storage): Initialize scm_protects.
1332 * root.c (scm_protects): New element of scm_sys_protects.
1334 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
1336 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1338 * libguile.h: Added #include "libguile/net_db.h".
1340 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
1341 30 change. That file is only meant for communication between the
1342 configuration process and load.c. If code linked against libguile
1343 wants to get at the paths mentioned in libpath.h, it can call
1344 functions declared in load.h.
1346 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1348 * libguile.h: Removed #include "libguile/fdsocket.h"
1350 * net_db.c: Added #include <sys/socket.h>.
1352 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
1354 * filesys.c (scm_input_waiting_p): use select in preference to
1355 FIONREAD, since the latter doesn't detect EOF.
1356 Throw error if neither select nor FIONREAD available.
1358 * socket.c (scm_connect): take a port, not a fd object.
1359 (scm_fill_sockaddr): throw an error if fam is not recognised.
1360 (scm_bind): use scm_fill_sockaddr.
1361 (scm_listen): take a port, not a fd object.
1362 (scm_accept): take and return a port. return #f in the car if
1363 address can't be got
1364 (scm_sock_fd_to_port): new procedure.
1365 (scm_socket): use scm_sock_fd_to_port.
1366 (scm_addr_vector): throw error if unrecognised address type.
1367 take an extra argument with the calling procedure name.
1368 (scm_getsockname): take a port. return #f if address can't be got.
1369 (scm_getpeername): take a port. return #f if address can't be got.
1370 (scm_recvfrom): take a port. return #f for address component if can't
1372 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
1373 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
1375 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
1377 * throw.c (scm_internal_catch): Make body funcs and handler funcs
1378 use separate data pointers, to allow them to be designed
1379 independently and reused.
1380 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
1381 Renamed from catch_body, catch_handler, and uncaught_throw; made
1383 (struct scm_catch_body_data): Renamed from catch_body_data; moved
1385 (scm_catch): Use the above.
1386 (scm_throw): Don't bother printing a message for an uncaught
1387 throw; we establish a default handler in init.
1388 * throw.h (scm_internal_catch): Prototype updated.
1389 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
1391 (struct scm_body_thunk_data): New structure, used as data
1392 argument to scm_body_thunk.
1393 * init.c (struct main_func_closure): New structure, packaging up
1394 the data to pass to the user's main function.
1395 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
1396 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
1397 scm_internal_catch to establish a catch-all handler, using
1398 scm_handle_by_message. This replaces the special-case code in
1400 (invoke_main_func): Body function for scm_internal_catch; invoke
1401 the user's main function, using the main_func_closure pointer to
1402 decide what to pass it.
1403 * root.c (struct cwdr_body_data): Remove handler_proc member.
1404 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
1405 (cwdr_handler): Removed.
1407 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1409 * socket.h (SCM_P): update bind prototype.
1410 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
1411 include "feature.h".
1412 (scm_socket): return a port, not a file descriptor object.
1413 include "fports.h" and <unistd.h>
1414 (scm_bind): take a port, not a file descriptor object.
1415 take an extra argument for address args.
1417 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
1418 INADDR_NONE, INADDR_LOOPBACK.
1420 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1422 * init.c: include net_db.h and not fdsocket.h.
1423 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
1425 * Makefile.am: corresponding changes.
1426 * socket.h: renamed from fdsocket.h, fix names.
1427 * net_db.h: renamed from socket.h, fix names.
1428 * socket.c: renamed from fdsocket.c.
1429 remove _sys from procedure names.
1430 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
1431 add "socket" to features list.
1432 * net_db.c: renamed from socket.c.
1433 remove _sys from procedure names.
1434 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
1435 add "net-db" to features list.
1436 include "net_db.h". don't include <sys/socket.h> or
1439 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1441 * tags.h (scm_tags): Removed comma at end of last enumerator.
1443 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
1445 Don't use GCC extensions to allocate space for debugging frames.
1446 (Here he goes again! Why do we put up with this?!)
1447 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
1448 an scm_debug_info structure, not an in-line array of them. Add
1449 'info' member, to say how many vect elements we've used, for eval
1451 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
1452 a new variable debug_info_end to mark the end of vect, instead of
1453 the address of the 'info' pointer itself.
1454 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
1455 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
1456 (SCM_APPLY): Explicitly allocate space for debug.vect.
1457 * debug.c (scm_m_start_stack): Same, for vframe.vect.
1458 * stacks.c: Adjusted for new debug frame structure.
1459 (RELOC_INFO, RELOC_FRAME): New macros.
1460 (stack_depth, read_frames): Use them, and new scm_debug_frame
1461 element 'info', instead of magically knowing that eval frames have
1462 an info pointer sitting after vect.
1463 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
1465 (scm_init_stacks): Formatting tweaks.
1467 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
1469 Give GCC more control flow information, so it can be sure that
1470 variables aren't used uninitialized.
1471 * error.h (scm_error, scm_syserror, scm_syserror_msg,
1472 scm_sysmissing, scm_num_overflow, scm_out_of_range,
1473 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
1474 scm_misc_error): Tell GCC that these functions never return.
1475 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
1476 out the field type, call abort if SCM_ASSERT returns, to placate
1478 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
1479 scm_wta ever returns. We can't handle this case anyway, and this
1480 gives the optimizer more information.
1481 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
1482 scm_wta ever returns.
1484 In some cases, the code is fine, but GCC isn't smart enough to
1485 figure that out; this usually happens when one variable is only
1486 initialized and used when a particular condition holds true, and
1487 we know that condition will never change within a given invocation
1488 of the function. In this case, we simply initialize the variables
1489 to placate the compiler, hopefully to a value which will cause a
1490 crash if it is ever actually used.
1491 * print.c (scm_iprin1): Initialize mw_pos.
1492 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
1493 * throw.c (scm_ithrow): Initialize dynpair.
1494 * unif.c (scm_uniform_vector_ref): Initialize cra.
1495 * struct.c (init_struct): Initialize prot.
1496 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
1498 * strports.c (scm_eval_0str): Don't return uninitialized garbage
1499 if EXPR contains no expressions.
1501 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
1503 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
1504 cause an infinite loop (???). So much for the algebraic
1505 equivalency of variable-sized arrays and alloca...
1507 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
1509 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
1510 a SCM boolean, not a C boolean.
1512 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
1514 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
1515 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
1516 rules for raising scm_mtrigger. Previously, unfortunate but not
1517 unlikely circumstances could result in almost constant invokation
1518 of the gc. Now, this situations should be less likely, but they
1519 are not prevented completely.
1521 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
1523 * numbers.c (scm_fuck): Procedure removed; looks like old test
1525 * numbers.h: Prototype removed.
1527 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
1529 * debug.h (scm_debug_frame): Change `vect' member from an in-line
1530 array to a pointer, to match my Nov 21 change in eval.c.
1532 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1534 * libguile.h: Added #include "libguile/backtrace.h", #include
1535 "libguile/stacks.h".
1537 * strings.c (scm_string scm_make_string scm_string_ref
1538 scm_string_set_x scm_string_equal_p scm_string_append):
1539 Bugfix according to scm patch from Aubrey Jaffer:
1540 Corrected long-standing
1541 (not (eqv? (integer->char 128)
1542 (string-ref (make-string 1 (integer->char 128)) 0)))
1543 bug found by John Kozak <jk@noontide.demon.co.uk>.
1545 * strports.c, strports.h: Make scm_eval_0str return the value of
1546 the last expression evaluated (previously, it returned void).
1548 * strports.c, strports.h: New function: scm_read_0str. Does what
1551 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1553 * simpos.c (scm_getenv): return #f if string can't be found in the
1554 environment instead of throwing an exception, for compatibility
1555 with numerous other systems.
1557 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
1559 * Makefile.am (.c.x): Use guile-snarf.
1560 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1562 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1564 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1566 * backtrace.c (scm_display_error_message): Made non-static, and
1567 renamed from display_error_message.
1568 * backtrace.h (scm_display_error_message): Added extern decl.
1569 * throw.c (uncaught_throw): Use it to display the error message.
1571 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1573 * inet_aton.c: Use #if 0, not #ifdef 0.
1575 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1577 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1578 to convert the returned value.
1579 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1580 the offset argument.
1582 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1584 Add new interface to catch/throw, usable from C as well as
1586 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1587 (scm_internal_catch): New function, replaces...
1588 (scm_catch_apply): Deleted.
1589 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1590 mechanism which is a bit more code, but can be used nicely from C
1591 and implement the Scheme semantics as well.
1592 (scm_internal_catch): This is the replacement; it's named after
1593 the analogous function in Emacs.
1594 (scm_catch): Reimplemented in terms of the above.
1595 (struct catch_body_data, catch_body, catch_handler): New
1596 functions, used by scm_catch.
1597 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1598 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1599 support for new cwdr.
1601 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1604 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1606 * acconfig.h: Added DYNAMIC_LINKING symbol.
1607 * configure.in: Add option and checks for dynamic linking.
1608 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1609 dynl.h: New files for dynamic linking support.
1610 * Makefile.am (libguile_a_SOURCES):
1612 (modinclude_HEADERS): Added "dynl.h".
1613 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
1615 * init.c (scm_boot_guile_1): Call
1616 scm_init_dynamic_linking to initialize dynamic linking support.
1618 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
1620 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
1621 (as we Schemers say). It needs to be global, so that I can tweak
1622 it for the proper operation of unexec.
1623 (scm_boot_guile_1_live): New variable, see above.
1625 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
1627 * guile-snarf.sh: Removed.
1628 * PLUGIN/guile.libs: Added dependency for -lm.
1629 * acinclude.m4: Renamed from aclocal.m4.
1630 * PLUGIN/greet: Removed.
1631 * Makefile.am, aclocal.m4: New files.
1632 * configure.in: Updated for Automake.
1634 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
1636 * eval.c (scm_definedp): Use top_level_lookup_closure_var
1637 and not top_level_lookup_thunk_var.
1639 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
1641 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
1643 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
1645 * eval.c (scm_definedp): Incompatibly changed to be a builtin
1646 Scheme function, instead of syntax. Single argument is now a
1649 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1651 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1652 scm_ra_divide): Properly terminate statements passed as arguments
1653 to IVDEP macros. (Thanks to Bernard Urban.)
1655 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1656 with non-constant sizes. (Thanks to Bernard Urban.)
1658 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1660 It's an "eval closure", not an "eval thunk." A thunk is a
1661 function of no arguments.
1662 * root.h (struct scm_root_state): Renamed
1663 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1664 (scm_top_level_lookup_closure_var): Renamed from
1665 scm_top_level_lookup_thunk_var.
1666 * root.c (mark_root): Uses changed.
1667 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1668 * init.c (scm_start_stack): Uses changed.
1669 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1670 Change scheme-visible name to *top-level-lookup-closure* from
1671 *top-level-lookup-thunk*.
1673 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1675 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1676 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1678 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1680 * gc.c (struct scm_heap_seg_data): Doc fixes.
1682 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1683 sweeping. Then, prepend each segment's free cells to its
1684 freelist, rather than wiping out the old value. (Thanks to Marius
1687 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1688 scm_check_freelist, scm_debug_newcell): New functions and
1689 variables, for debugging freelist problems.
1690 * pairs.h (SCM_NEWCELL): New debugging version added.
1691 * gc.h (scm_debug_newcell): Added extern declaration, used by
1692 debugging version of SCM_NEWCELL.
1694 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1696 On some systems <libc.h> conflicts with <unistd.h>, and should not
1697 be #included at all.
1698 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1699 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1700 * configure.in: Call it.
1701 * posix.c, filesys.c: Use its results to decide whether or not to
1703 * configure, scmconfig.h.in: Rebuilt with autoconf and
1706 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1708 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1709 pointer to the stdio stream before calling scm_setbuf0, so the
1710 latter will be able to retrieve it. I'm surprised this didn't
1711 segfault earlier. (Thanks to Christopher Lee.)
1713 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1715 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1718 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1720 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1721 number of stack narrowing specifier pairs. The first specifier in
1722 a pair controls inner border, the second the outer border. A
1723 number means cut that number of frames, a procedure object means
1724 cut until that object is found in operator position in a frame.
1726 * root.c (cwdr): Bugfix.
1728 * read.c: Recording of positions disabled by default.
1730 * procs.c (scm_closure_p): New function.
1732 * posix.c (scm_tmpnam): New function.
1734 * load.c: Added #include "throw.h".
1735 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1738 * load.c, load.h (scm_read_and_eval_x): New function.
1740 * eval.c: Renamed debug option "deval" to "debug".
1742 (scm_eval_x): `eval!' is no longer accessible from the scheme
1743 level. Motivation: We can't allow operations which introduce
1744 glocs into the scheme level. Guile's type system can't handle
1745 these as data. Use `eval' or `read-and-eval!' as replacement.
1747 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
1748 SCM_CONSP since this is a macro!; Set vframe.prev to
1749 scm_last_debug_frame instead of 0. In this way we can look
1750 "above" the virtual start stack frame if we wish.
1751 (scm_debug_hang): New function: Useful for debugging Guile in
1752 certain tricky situations. Will probably be removed later...
1754 * debug.h: Changed semantics of debug option "backtrace". This
1755 option now only indicates whether we want automatic backtrace at
1758 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1760 * ports.c: #include "filesys.h"
1761 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
1763 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
1764 Motivation: This is system specific code which is related to file
1765 I/O. It also may use select. Added code by Gary Houston to
1766 detect presence of character in stdio buffers.
1768 * libguile.h: #include "libguile/libpath.h"
1770 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
1771 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
1772 SCM_SITE_DIR; Install libpath.h among the other include files.
1774 * load.c, load.h (scm_sys_package_data_dir): New function.
1776 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1778 * stacks.h: Bugfix: Don't use tail-array length field as stack
1779 length field! This screwed GC.
1781 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1783 * _scm.h: Added #ifndef around definition of macros min and max.
1785 * __scm.h: Added hooks for threads to plugin to in ints protection
1786 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
1787 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
1788 the main code in these macros duplicated and spread over multiple
1789 files. Renamed SCM_THREADS_SWITCHING_CODE ->
1790 SCM_THREAD_SWITCHING_CODE.
1792 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
1794 * snarf.h: New file.
1795 * guile-snarf.sh: New file.
1796 * Makefile.in (inner_h_files): Added snarf.h
1797 (ancillary, install, uninstall, distclean): Added actions for
1799 (.c.x): Use guile-snarf.
1800 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
1801 (gen_c_files): Note that these depend on guile-snarf.
1802 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
1803 now in "snarf.h". Added #include "snarf.h" to get them.
1804 * libguile.h: Added #include "snarf.h".
1805 (Patches applied and tweaked by Jim Blandy.)
1807 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
1809 * socket.c: Use K&R style declaration for 'close'; the GNU coding
1810 standards suggest against providing prototypes for system
1811 functions. Thanks to Greg Troxel.
1813 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1815 * strports.c (scm_eval_0str): New function.
1816 #include "read.h", to get prototype for scm_read.
1817 * Makefile.in (strports.o): Update dependencies.
1818 * strports.h: New prototype.
1820 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
1821 scheme name from "int?" to "integer?". It seems to do the job.
1822 * numbers.h: Rename prototype too.
1823 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
1826 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
1827 scm_num_eq_p): Rename these according to R4RS conventions: call
1828 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
1829 to making libguile R4RS compliant without ice-9...
1831 * load.c (scm_sys_search_load_path): Search for files under all
1832 extensions listed in the %load-extensions variable. If FILENAME
1833 is absolute, return it unchanged, without searching the load path.
1834 (scm_loc_load_extensions): New variable, pointing to
1835 %load-extensions' value cell.
1836 (scm_init_load): Initialize it, and the value it points to.
1837 (scm_primitive_load_path): Improve error reporting.
1839 * load.c (scm_loc_load_hook): New variable, pointing to value cell
1840 of new Scheme variable %load-hook.
1841 (scm_primitive_load): Apply %load-hook to filename.
1843 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
1845 * configure.in: add tests for figuring out whether buffered data
1846 is available in a FILE structure, which is needed by char-ready.
1848 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
1851 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
1852 exceptions using misc_error instead of syserror. It seems a bit
1853 odd to throw an exception if a string can't be found in the
1854 environment, but it's consistent with open-file, stat etc.
1855 (simpos.h): remove sys_ from getenv.
1857 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
1858 occurs, throw an error instead of returning errno. Return value
1860 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
1862 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
1864 * filesys.c (scm_stat2scm): derive file type and permissions from
1865 the stat mode and append them to the returned vector.
1866 There isn't much overhead in doing this and it avoids the need to
1867 work with S_IRUSR et al. in Scheme.
1868 Define symbols scm_sym_regular etc.
1869 (scm_init_filesys): don't intern S_IRUSR etc.
1871 * load.c: change s_try_load and s_try_load_path to s_primitive_load
1872 and s_primitive_load_path.
1874 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
1876 * error.h: don't declare error symbols. prototype for scm_misc_error.
1878 * stackchk.c (scm_stack_overflow_key): defined here instead of in
1881 * error.c: use SCM_SYMBOL to set up error keys.
1882 scm_misc_error: new procedure.
1884 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
1886 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
1887 between `#!' and `!#' is ignored.
1888 (skip_scsh_block_comment): New function.
1890 * feature.c (scm_set_program_arguments): New argument, FIRST.
1891 * feature.h: Update prototype.
1892 * init.c (scm_boot_guile_1): Pass new argument to
1893 scm_set_program_arguments.
1895 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1897 * init.c (scm_start_stack): Don't initialize scm_progargs here.
1898 (scm_boot_guile): Call scm_set_program_arguments here, later than
1899 the old initialization.
1901 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
1902 initialization procedure.
1903 - Delete in, out, err arguments; there are other perfectly good
1904 ways to override these when desired.
1905 - Delete result argument; this function shouldn't ever return.
1906 - Rename init_func argument to main_func, for less confusion.
1907 - Delete boot_cmd argument; main_func is more general.
1908 -Add 'closure' argument, to help people pass data to main_func
1909 without resorting to global variables.
1910 - Abort if reentered; don't bother returning an error code.
1911 - Call scm_init_standard_ports to set up the default/current
1912 standard ports; no need to pass them to scm_start_stack.
1913 - Remove code to evaluate the boot_cmd, and start the repl; let
1914 the user do something like that in main_func if they want.
1915 - Remove code to package up a return value; main_func can do any
1917 - Call exit (0), instead of returning.
1918 (scm_start_stack): Don't initialize the I/O ports here; that's
1919 weird. Delete in, out, err arguments. Move guts to
1920 scm_init_standard_ports, scm_stdio_to_port.
1921 (scm_init_standard_ports): New function, to set up current and
1922 default standard ports.
1923 (scm_start_stack, scm_restart_stack): Make these static.
1924 * init.h (scm_boot_guile): Adjust declaration.
1925 (scm_start_stack, scm_restart_stack): Remove externally
1926 visible declarations for these.
1927 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
1929 * fports.c (scm_stdio_to_port): New function. Its guts used to be
1930 written out several times in scm_start_stack.
1931 * fports.h: New declaration for the above.
1933 * feature.c (scm_set_program_arguments): New function.
1934 * feature.h: New declaration for the above.
1936 * ports.c: Formatting tweak.
1938 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
1940 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
1941 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
1942 for obtaining the address of a car or cdr field. Motivation:
1943 &SCM_CXR make assumptions about the internal structure of the
1946 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
1947 Motivation: see SCM_CXRLOC.
1949 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
1950 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
1951 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
1952 Motivation: Safer use. Some other macros are defined in terms of
1953 these operations. If these are defined using the SCM_SETCXR
1954 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
1955 to inefficiency and an <e1> with side-effects could potentially
1956 break. Also, these particular operations are heavily utilized in
1957 the garbage collector. In unoptimized code there will be a
1960 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
1961 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,

1965 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
1966 vports.c: Cleaned up use of pairs: Don't make any special
1967 assumptions about the internal structure of selectors and
1968 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
1969 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
1970 (Among other things, this change makes it easier to build Guile
1971 with certain compilers which have problems with casted lvalues.)
1973 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1975 * stacks.c: Improve selection of relevant stack frames when making
1976 a stack object. Introduce one level of indirection in the stack
1977 object to make it possible to "narrow" to a certain region of the
1978 stack. This facilitates making use of more clever algorithms (not
1979 implemented) for selecting relevant frames and gives a cleaner
1980 design since selection of frames can be done independently of
1981 extraction of frames from the real stack.
1982 (scm_stack_id): Also take #t as argument which means look at
1985 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
1986 Turn n_tail into an integer directly representing current number
1987 of frames in stack. Add field tail.
1989 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
1991 * debug.c (scm_make_memoized): Made it available at scheme level.
1992 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
1993 SCM_NIMP before applying heavier predicates in argument checking.
1994 (scm_local_eval): Also take memoized object as argument.
1996 * backtrace.c (scm_display_error): Just a safety measure: Stacks
1997 aren't created with zero length, but should such a strange
1998 creature suddenly turn up...
2000 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
2002 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
2003 `del', for the sake of C++ compilers. (Patch applied by JimB.)
2005 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
2007 * variable.c (scm_make_variable): Make the name hint optional, as
2009 (anonymous_variable_sym): Renamed from variable_sym. All uses
2012 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
2013 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
2014 of scm_primitive_load_path was also changed to
2015 "primitive-load-path", from "%try-load-path". Callers changed.
2016 We'd like to respect the convention that a function named
2017 "try-mumble" should behave just like the function called "mumble",
2018 but return #f instead of signalling some error.
2019 * load.h: Rename prototypes.
2021 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2023 * print.c (make_print_state, grow_print_state), print.h: Modified
2024 the print state representation: Don't use a tail array for
2025 recording of circular references. Resizing of the print state
2026 structure invalidates the print state pointer. To avoid passing
2027 around an indirect print state reference to all printing
2028 functions, we instead let the print state reference a resizable
2031 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2033 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
2034 Don't crash when passed an improper list terminated by a
2035 non-immediate value.
2037 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
2039 Allocate data for structures on an eight-byte boundary, as
2040 required by the tagging system.
2041 * struct.c (alloc_struct): New function.
2042 (scm_make_struct, scm_make_vtable_vtable): Call it.
2043 * struct.h (scm_struct_n_extra_words): Bump to 3.
2044 (scm_struct_i_ptr): New "field".
2045 * gc.c (scm_gc_sweep): When we need to free the data, use the
2046 information stored by alloc_struct to find the beginning of the
2047 block allocated to the structure, so we can free it.
2049 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2051 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
2054 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
2055 (scm_debug_info): New member: id.
2057 * stacks.c: Stacks are now represented as structs; Stacks have an
2058 id given to them by `start-stack'.
2059 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
2061 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
2062 Changed stack representation.
2064 * debug.c (scm_procedure_name): Try procedure property `name' for
2065 compiled closures aswell.
2067 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
2069 * eval.c: scm_i_name moved to gsubr.c
2070 (scm_m_define): Record names of all kinds of procedure
2071 objects. (Earlier, only closures were recorded.)
2073 * procprop.h: Added declaration of scm_i_name.
2075 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
2076 (scm_make_gsubr): Record names of compiled closures.
2078 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2080 * debug.c, debug.h: Removed obsolete code.
2082 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
2083 stacks.c: Renamed regs --> scm_contregs.
2085 * print.c (scm_free_print_state): Cleanup print state before
2086 returning it to pool. It is better to do it here than in
2087 scm_prin1 since scm_prin1 is called often.
2089 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
2090 s_set_source_property_x): Check that first argument is a pair or a
2093 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
2094 scm_i_line, scm_i_column and scm_i_breakpoint global.
2096 * init.c: Added #include "backtrace.h" and #include "stacks.h".
2097 (scm_boot_guile_1): Added calls to scm_init_backtrace and
2100 * debug.h: Added debug object smob declaration and macro
2103 * configure.in: Build with backtrace.o and stacks.o if debug
2106 * Makefile.in: Added entries for new files: backtrace.c,
2107 backtrace.h, stacks.c and stacks.h.
2109 * symbols.c (scm_sym2ovcell): Fixed documentation.
2111 * _scm.h (min, max): Added.
2113 * async.c: Moved `min' macro to _scm.h.
2115 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
2116 SCM_BACKTRACE_INDENT.
2118 * eval.c: Added new debug options `maxdepth' and `indent'.
2120 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
2122 * print.h: Added selector SCM_PRINT_STATE.
2124 * print.c: New functions: scm_make_print_state,
2125 scm_free_print_state.
2127 * print.h: Added declarations for scm_make_print_state,
2128 scm_free_print_state.
2130 * debug.c (scm_m_start_stack): New acro.
2132 * debug.h: Small cleanup.
2134 * init.c (scm_boot_guile_1): Moved scm_init_debug below

2159 declare functions with prototypes. (Patch thanks to Marius
2162 More prototype-related changes from Marius Vollmer:
2163 * gdb_interface.h: Wrapped header file in #ifdef/#endif
2164 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
2165 * ports.h (ptobfuns): Added prototypes. This means some casting in
2167 * fports.c: Added casts for initializations, since the functions
2168 are defined to take FILE * as their stream argument, not SCM.
2169 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
2170 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
2171 to `char *str_data' to conform to prototype.
2173 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2175 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
2177 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
2179 * stime.c, stime.h: use SCM_P method.
2181 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2183 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
2184 be given at least two arguments. Insist that lst's last element
2185 be a list, but don't make any requirements of its predecessors.
2187 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2189 * eval.c (scm_nconc2last): Revert last change; there seems to be
2190 other stuff going on here.
2192 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2194 * eval.c (scm_nconc2last): Make sure that each element of lst
2195 (which is a list of argument lists, except for the tail) is a
2196 proper list, i.e., finite and terminated by '().
2198 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2200 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
2203 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
2204 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
2207 * vectors.c (scm_make_vector): Fill vectors with the undefined
2208 value, to help make Guile Scheme code more portable to other
2211 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
2212 * symbols.h, tags.h: Doc fixes.
2214 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
2216 * async.c (scm_take_signal): Doc fixes.
2218 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
2220 * numbers.c (scm_divbigint): When the remainder is zero, we don't
2221 want to subtract it from the modulus; we just want to leave it
2224 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
2226 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
2229 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
2231 * throw.c (scm_catch_apply): Finished implementation of
2234 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2236 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
2238 (scm_init_filesys): set "i/o-extensions" feature.
2241 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
2243 * Makefile.in (root.o): Correct dependencies.
2245 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
2247 * Makefile.in: Added dependency entry for root.o.
2249 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
2250 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
2252 * init.c (scm_start_stack): Set initial root continuation number
2255 * procs.c: New function: scm_thunk_p.
2257 * procs.h: Added declarations of scm_thunk_p.
2259 * root.c: Renamed `call-with-new-root' -->
2260 `call-with-dynamic-root'.
2261 (cwdr): Removed allocation of new root state. This should be done
2262 separately by use of scm_make_root.
2263 (scm_apply_with_dynamic_root): New function: Does what it
2264 sounds like. Needed when spawning threads.
2266 * root.h: Added member last_debug_frame to root state.
2267 Added #include "libguile/debug.h"
2269 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
2270 arguments. The motivation is that code in root.c needs catch
2271 functionality, and we want to avoid code duplication.
2272 New functions: scm_catch, scm_lazy_catch. These are wrappers for
2273 scm_catch_apply. scm_lazy_catch is intended to introduce catch
2274 handlers that run without popping the stack into the dynwind
2277 * throw.h: Added prototypes for scm_catch_apply and
2280 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2282 * root.h (scm_root, scm_set_root): Decouple thread support details
2283 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
2284 SCM_SET_THREAD_LOCAL_DATA.
2286 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
2287 and tortoise scanning loop.
2289 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
2291 * Makefile.in: Rebuild dependencies.
2293 * libguile.h: #include "libguile/print.h" before "smob.h", since
2294 the latter uses the print_state structure.
2296 * throw.c (scm_ithrow): Use the correct variable when checking to
2297 see if a given element of scm_dynwinds is a valid catch.
2299 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
2300 structure, abort; don't just silently ignore the garbage.
2302 * _scm.h: #include "print.h" here, since it seems to be used just
2304 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
2305 strports.c, unif.h: Don't #include "print.h".
2307 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2309 * feature.h (scm_loc_features): Removed external declaration.
2310 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
2312 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2314 * feature.c (scm_init_feature): Added threads feature (needs to be
2315 initialized here, since features doesn't exist when
2316 scm_init_threads is called).
2318 * libguile.h: Added #include "libguile/../threads/threads.h".
2319 (This is a kludge to get thread support working. This should be
2322 * configure.in, acconfig.h: Added flags for thread support.
2324 * scmsigs.c: Define `signal' to be `pthread_signal' if using
2327 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
2328 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
2331 * _scm.h: Added conditional #include "threads.h"
2333 * __scm.h (SCM_ASYNC_TICK): Added call to macro
2334 SCM_THREADS_SWITCHING_CODE.
2336 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
2337 allocate the basic dynamic root object.
2338 (scm_boot_guile): Added call to scm_init_root.
2340 * root.c, root.h: Added root smob.
2341 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
2342 functions: Implements dynamic roots mostly according to spec in
2343 SCM manual. Main difference is that the second argument is a
2344 throw handler rather than an error "thunk".
2346 * root.h: Added declaration of scm_init_root.
2348 * root.c: Added #include "genio.h", #include "smob.h", #include
2349 "pairs.h", #include "throw.h", #include "dynwind.h", #include
2351 (scm_init_root): Added #include "root.x".
2353 * throw.c: Added #include "stackchk.h"
2354 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
2355 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
2356 can be used in scm_call_with_new_root; Added reenabling of stack
2357 checking when catching a throw.
2359 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
2361 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
2363 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
2364 element is not found, as per R4RS.
2366 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2368 * list.c: Doc fixes throughout.
2370 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2372 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
2373 declare the char * to be const. Avoids a warning in rgx.c.
2375 * ports.h: spelling fix.
2377 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
2380 * load.c (scm_sys_try_load_path): throw an error if file not found
2381 (like it says it in NEWS).
2383 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2385 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
2386 PROPS slot to '(), not #f; it's an empty alist.
2388 * throw.h, throw.c: Use SCM_P instead of #if hair.
2390 Remove special support for uncaught throws; see throw.c for
2392 * throw.c (uncaught_throw): New function.
2393 (scm_ithrow): Call uncaught_throw if we don't find a throw
2394 target; don't mess with scm_bad_throw_vcell.
2395 (scm_bad_throw_vcell): Variable deleted.
2396 (scm_init_throw): Don't initialize it.
2398 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
2401 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2403 * numbers.c (scm_istr2int): If the number is short (as most
2404 numbers are), just call scm_small_istr2int to deal with it.
2405 (scm_small_istr2int): New function, created by un-#ifdefing the
2406 non-bignum version of scm_istr2int and renaming it.
2408 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
2410 * load.c (scm_sys_try_load): don't check whether value returned
2411 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
2412 Change the Scheme name from %try-load to primitive-load.
2414 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
2415 Can avoid passing a message, allowing it to be derived in the
2416 error handler (e.g., if we want to throw to the key both from
2419 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
2421 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
2422 references now have a new appearance which is more compact and
2423 also gives a clue about what the target of the reference is.
2424 By setting parameters in the print state, more fancy printing can
2425 be achieved. This is used by the (not yet commited) backtrace
2428 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
2430 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
2433 * print.c: Added #include "struct.h". Removed function
2436 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
2437 scm_iprin1. Removed prototype for scm_prlist.
2439 * arbiters.c (prinarb),
2440 async.c (print_async),
2441 debug.c (prindebugobj, prinmemoized),
2442 eval.c (prinprom, prinmacro),
2443 filesys.c (scm_fd_print, scm_dir_print),
2445 mallocs.c (prinmalloc),
2446 numbers.c, numbers.h (scm_floprint, scm_bigprint),
2447 smob.h (scm_smobfuns),
2448 srcprop.c (prinsrcprops),
2450 unif.c, unif.h (scm_raprin1, rapr1),
2451 variable.c (prin_var): Changed argument `int writing' to
2452 `scm_print_state *pstate'.
2454 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
2455 that it will be called before scm_init_print.
2457 * print.c (scm_prin1): Print states are now allocated when calling
2458 scm_prin1 and then passed around to all printing functions as an
2459 argument. A cache `print_state_pool' enables reuse of print
2461 (scm_make_print_state): New function.
2462 (scm_iprin1): Adaption to print states.
2463 (scm_iprlist): An initial "hare and tortoise" scan brings down
2464 time complexity to O (depth * N). (Better time complexity will be
2465 achieved when the printing code is completely rewritten.)
2467 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2469 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
2470 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
2471 it gets done whether or not the cache variable has a value.
2473 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2475 Distinguish #f and ().
2476 * __scm.h: #undef SICP.
2477 * pairs.h (SCM_EOL): Delete this definition, equating it with
2479 * tags.h (SCM_EOL): Give it a new definition here; I think I found
2480 the value it used to have. Doc fixes, too.
2482 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
2484 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
2485 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
2486 Lord's implementation of structs, allowing for tail arrays as
2487 described in the manual. Also fixed some bugs. (Both the interface
2488 and the implementation should be improved.)
2490 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
2492 * print.c, print.h: Closures now print like #<procedure foo (x)>.
2493 People who whish to see the source can do `(print-enable 'source)'.
2494 Removed #ifdef DEBUG_EXTENSIONS.
2496 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2498 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
2499 integer (assuming for now accepting an integer is a good thing).
2501 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2502 %S will be used instead for write'ing arguments.
2504 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2505 asserts. fix a few other asserts.
2506 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2507 scm_uniform_vector_ref, scm_array_set_x,
2508 scm_dimensions_to_unform_array): change args in
2509 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2510 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2511 scm_substring_fill_x): likewise.
2512 gsubr.c (scm_gsubr_apply): likewise.
2513 eval.c (SCM_APPLY): likewise.
2515 * eval.c (4 places): replace scm_everr with lgh_error or
2518 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2519 scm_memory_error): new procedures.
2520 scm_everr: deleted. can use scm_wta, dropping first two args.
2521 scm_error: convert NULL subr to SCM_BOOL_F.
2523 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2526 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2529 * error.c, error.h: new error keys: scm_arg_type_key,
2530 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2532 scm_wta: reimplement using lgh_error instead of scm_everr.
2534 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2536 * gdbint.c: scm_lread now has one more argument.
2538 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2539 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2540 loading source from non-file ports, which, e. g., happens when
2541 using the Emacs interface).
2543 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2546 * read.c: Added code for recording of positions of source code
2547 expressions; New functions: recsexpr, scm_lreadrecparen;
2548 _scm_make_srcprops --> scm_make_srcprops
2549 (scm_flush_ws): Removed updating of positions counters. This work
2550 is already done by scm_gen_getc
2552 * read.h: Added prototype for scm_lreadrecparen
2554 * print.c: Added #include "alist.h"
2556 * eval.c: Added #include "hash.h"
2558 * eq.c: Added #include "ramap.h"
2560 * options.c: Documentation fixes.
2562 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
2563 (scm_init_srcprop): Adjusted size of initial source-whash. Name
2564 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2565 --> scm_make_srcprops
2567 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2568 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2569 function calls in the definition of the whash access macros.
2571 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2573 * init.c (scm_boot_guile): Add level of indirection to
2574 scm_boot_guile_1() to ensure that stack base pointer is properly
2575 initialized. There was no guarantee that variable i was the
2576 highest/lowest variable on stack (i.e. the call frame of
2577 scm_boot_guile was not completely protected from gc).
2579 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2581 * ports.h (scm_port_table): put back file_name, it will be used to
2582 support debugging. Undo related changes in fports.c, ioext.c,
2585 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2587 * ports.h (scm_port_table): remove file_name member for now, it seems
2589 * fports.c (scm_open_file): don't set file_name in PTAB.
2590 (prinfport): don't use file_name in PTAB.
2591 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2592 * ports.c (scm_add_to_port_table): don't intialize file_name.
2593 (scm_port_file_name): remove for now.
2594 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2596 * fports.h (scm_mkfile): prototype deleted.
2597 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2599 * debug.c, unif.c: use scm_out_of_range instead of
2600 wta for range errors (ASSERT still needs work).
2602 * error.c, error.h (scm_out_of_range): new procedure.
2604 * error.c, error.h (scm_out_of_range_key): new key.
2606 * posix.c (scm_sync): #else was missing.
2608 * error.c, error.h: append _key to names scm_num_overflow and
2611 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2612 of consing an empty list.
2613 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2614 of macros, saves code and string space.
2615 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2616 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2617 lower case. Rename scm_syserror_m to scm_syserror_msg.
2618 error.h: prototypes for new procedures.
2620 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2622 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2624 * error.c, error.h: setup scm_num_overflow key.
2626 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2627 Remove definition of SCM_OVSCM_FLOW.
2629 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2631 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2632 explicit message and args.
2634 * error.c, error.h, __scm.h: change system_error_sym to
2637 * error.c (system_error_sym): remove leading %% from the Scheme name
2640 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2642 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2644 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2645 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2646 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2647 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2648 renamed. (These were introduced by unsupervised name
2651 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2653 * print.c: Added code for detection of circular references during
2654 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2655 a hook for printing of closures (accessible via print options).
2656 This leads to a split of calls to scm_iprin1 into two classes:
2657 elementary print operations (e. g. the code which prints a smob)
2658 still use scm_iprin1 while top level calls (like scm_display) use
2659 scm_prin1. scm_prin1 begins by clearing the data structure used
2660 to record reference information.
2662 * print.h: Added declarations of scm_prin1 and scm_prlist.
2664 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2666 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2668 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2670 * error.c (err_head): scm_iprin1 --> scm_prin1
2672 * debug.c: Adjusted header comment.
2676 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2678 * strerror.c: Doc fix.
2680 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2682 * gdbint.c (gdb_read): Now possible to run during GC.
2683 (unmark_port, remark_port): New functions.
2685 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2687 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2688 of allocating a new string object. Also, increase size by
2689 the factor 2 instead of 1.5.
2691 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2693 * __scm.h (SCM_P): Corrected to run under traditional C.
2695 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2698 * async.c: Calls to scm_sysintern corrected.
2700 * async.h (scm_async_clock): Redundant declaration removed.
2702 * continuations.c (scm_dynthrow): Redundant declaration removed.
2704 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2705 Definition typos corrected.
2707 * debug.h: Missing declarations of functions in debug.c added
2710 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2711 Missing declarations to functions in eval.c added.
2713 * filesys.c: Possibly uninitialized variable rv.
2715 * gc.h (scm_object_addr, scm_unhash_name): Missing
2716 declarations of functions defined in gc.c added.
2718 * genio.c: Possible typos str_data -> wstr_data. ???
2720 * genio.c: Possibly unintended shadowing of local variable
2721 `int c' (gotos out of scope of inner `c'). ???
2723 * init.c: Uninitialized `SCM last' may be used.
2725 * ioext.h: (scm_sys_isatty_p): Typo.
2727 * list.h (scm_list_head): Missing prototype for function in
2730 * numbers.c (scm_two_doubles): Changed from extern to static
2731 (is used only within numbers.c).
2733 * numbers.h: Repeated declarations removed.
2735 * ports.h (scm_close_all_ports_except): Declaration for the
2736 function defined in ports.c added.
2738 * posix.h: Missing declarations added.
2740 * procs.h (scm_make_subr_opt): Missing declaration added.
2742 * socket.h (scm_sys_gethost): Missing declaration added.
2744 * socket.h: Redundant declarations removed (they are in fdsocket.h).
2746 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
2747 Missing declarations added.
2749 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
2751 * struct.c: Uninitialized variable `SCM answer' may be used.
2753 * unif.c (l2ra): Declaration prototype.
2755 * unif.c (scm_array_equal_p): Dummy definition removed (it is
2756 defined in ramap.c).
2758 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
2759 Redundant declarations removed (they are in ramap.h).
2761 * variable.h (scm_make_udvariable,
2762 scm_make_undefined_variable): Declaration corrected to
2763 correspond variable.c.
2765 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
2766 Missing declarations added.
2768 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
2770 * Makefile.in (distclean): Don't forget to delete fd.h.
2772 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2774 * fd.h.in, tags.h: Trivial cleanups.
2776 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
2777 marksweep.h just declared functions from gc.c.
2778 * gc.h, libguile.h: Don't #include "marksweep.h".
2779 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2780 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
2781 dependencies updated.
2783 * libguile.h: Don't #include "files.h"; it's been deleted.
2785 * files.c (scm_sys_delete_file): Moved to filesys.c.
2786 File is now empty; deleted.
2788 * filesys.c: scm_sys_delete_file is now here. Remove
2789 #if's; they seem to rely on remnants of an old portability
2790 regimen. If the problems come up again, solve them properly,
2791 using autoconf. Specifically: Don't test M_SYSV, and #define
2792 remove to be unlink if it's #defined; don't use remove just
2793 because HAVE_STDC_HEADERS is #defined.
2794 * filesys.h: Add declarations for scm_sys_delete_file.
2795 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
2796 files.o, files.h, files.c, and files.x.
2797 * init.c: Don't #include "files.h", and don't call scm_init_files.
2799 Use SCM_P instead of PROTO; the latter intrudes on the user's
2801 * params.h: Deleted; definition of SCM_P moved to...
2802 * __scm.h: ... here, where it replaces PROTO macro.
2803 * libguile.h, smob.h: Don't #include "params.h".
2804 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
2805 smob.h: Fix prototypes accordingly.
2806 * Makefile.in: Update dependencies.
2807 (inner_h_files): Remove params.h.
2809 * gc.c: #include "gc.h"; every module should include its header,
2810 to let the compiler cross-check the declarations against the
2813 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
2814 simpos.h: #include "libguile/__scm.h".
2816 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
2818 * init.c: Don't forget to #include smob.h and init.h.
2819 * Makefile.in: Dependencies updated.
2821 * smob.h: Use PROTO instead of #if __STDC__.
2823 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
2825 * __scm.h: Doc fixes.
2827 * __scm.h, libguile.h: Use "quotes" in the #includes, not
2828 <angles>; this allows `make depends' to work properly.
2830 * libguile.h: #include smob.h and pairs.h before the others; they
2831 define typedefs used by other headers.
2833 C files should #include only the header files they need, not
2834 libguile.h (which #includes all the header files); the pointless
2835 recompilation was wasting my time.
2836 * Makefile.in (all .o dependency lists): Regenerated.
2837 * libguile.h: Don't try to get a definition for size_t here...
2838 * __scm.h: Do it here.
2839 * _scm.h: Since this is the internal libguile header, put things
2840 here that all (or a majority) of the libguile files will want.
2841 Don't #include <libguile.h> here; that generates dependencies on
2842 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
2843 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
2844 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and
2846 * alist.c: Get "eq.h", "list.h", "alist.h".

2858 * eq.c: Get "eq.h", "unif.h", "smob.h", "strorder.h",
2860 * error.c: Get "error.h", "throw.h", "genio.h", "pairs.h".
2861 * eval.c: Get "eval.h", "stackchk.h", "srcprop.h", "debug.h",

2865 * fdsocket.c: Get "fdsocket.h", "unif.h", "filesys.h".
2866 * feature.c: Get "feature.h".
2867 * files.c: Get "files.h".
2868 * filesys.c: Get "filesys.h", "smob.h", "genio.h".
2869 * fports.c: Get "fports.h", "markers.h".
2870 * gc.c: Get "async.h", "unif.h", "smob.h", "weaks.h",
2871 "genio.h", "struct.h", "stackchk.h", "stime.h".
2872 * gdbint.c: Get "gdbint.h", "chars.h", "eval.h", "print.h",

2878 * init.c: Get everyone who has an scm_init_mumble function:
2879 "weaks.h", "vports.h", "version.h", "vectors.h", "variable.h",
2880 "unif.h", "throw.h", "tag.h", "symbols.h", "struct.h",

2945 * print.h, read.h: #include "options.h", since everyone who uses
2946 either of these files will need that.
2948 * smob.h: #include "ports.h", "genio.h", and "print.h", since
2949 anyone who uses this file will need them to define the smob
2950 printing functions. Also, get markers.h, since people will need
2951 to #define the mark functions.
2953 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
2954 * ports.h: ... to here.
2956 * ports.h (scm_port_table_size): Explicitly give type as 'int';
2957 don't rely on archaic C default type rules.
2959 * fports.h: #include "libguile/ports.h", since you need that in
2960 order to parse this.
2962 * genio.h: #include "libguile/print.h", because you need that to
2963 parse this; don't bother #including "ports.h", since print.h gets
2966 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
2968 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
2969 this; it's now a reference to an element of *scm_root.
2971 * debug.h: Don't #include "options.h"; the compiler won't be able
2972 to find that once the headers are installed; instead, #include
2973 "libguile/options.h".
2974 * gc.h: Same, with marksweep.h.

2976 * scmhob.h: Same, with _scm.h.
2977 * smob.h: Same, with params.h.
2979 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
2980 C files; there's no need for this, and it forces recompilations
2983 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
2985 * error.c (scm_error): declare scm_error_callback.
2987 * error.h: prototype for scm_error_callback.
2989 * __scm.h: define lgh_error.
2990 (SCM_SYSERROR): redefine using lgh_error.
2992 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
2994 * error.c (scm_error): new procedure.
2996 * error.h: prototype for scm_error.
2998 * Makefile.in (install): install scmconfig.h from the current
2999 directory, not $(srcdir).
3001 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3003 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3004 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3005 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

3011 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3012 vports.h, weaks.h: #include "libguile/__scm.h", not
3013 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
3014 dependencies are within libguile properly.
3016 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3018 * Makefile.in (.c.x): Simplify; there's no need to run this rule
3019 when scmconfig.h doesn't exist.
3021 * load.c (scm_sys_try_load): Correct spelling.
3023 * feature.c (scm_loc_features): Make this static.
3025 * Makefile.in (libpath.h): Omit trailing slash from path. We
3026 shouldn't require it of users, so why put it here?
3028 Move code to initialize and search %load-path from ice-9 to C
3029 code, so we can use the load-path to find the ice-9 boot code;
3030 this makes it easier to run Guile without installing it. See
3031 corresponding changes in guile/Makefile.in.
3032 * feature.c: Move stuff concerned with the load path to load.c.
3033 (scm_compiled_library_path): Deleted.
3034 Don't #include libpath.h here.
3035 * feature.h: Don't mention scm_compiled_library_path.
3036 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
3037 <sys/stat.h>, and <unistd.h> (if present).
3038 (R_OK): #define if the system hasn't deigned to.
3039 (scm_loc_load_path): New variable.
3040 (scm_init_load_path, scm_sys_search_load_path,
3041 scm_sys_try_load_path): New functions.
3042 (scm_init_load): Initialize scm_loc_load_path to point to the
3043 value cell of the Scheme %load-path variable.
3044 * load.h: Add declarations for scm_sys_search_load_path,
3045 scm_sys_try_load_path.
3046 * init.c: Call scm_init_load_path.
3047 * Makefile.in (feature.o, load.o): Dependencies updated.
3049 * load.c, load.h: Rewrite using PROTO macro.
3051 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3053 * gc.c (scm_cellp): New function: C predicate to determine if an
3054 SCM value can be regarded as a pointer to a cell on the heap.
3056 * gc.h: Added declaration of scm_cellp.
3058 * gdb_interface.h: New file: The GDB interface header from the GDB
3061 * gdbint.c: New file: GDB interface.
3063 * gdbint.h: New file: GDB interface.
3065 * libguile.h: Added #include <libguile/gdbint.h>.
3067 * init.c (scm_boot_guile): Added scm_init_gdbint.
3069 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
3070 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
3071 found if object files and source are kept separate).
3073 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
3075 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
3077 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
3079 * configure.in: Don't substitute the values of TCL_SRC_DIR and
3080 TK_SRC_DIR; they're not relevant any more.
3082 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
3083 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
3085 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
3087 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
3088 search path, so we can find the <libguile/MUMBLE.h> headers.
3090 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
3092 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
3093 implicit in the .c.o rule.
3094 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
3097 Put the library path in a header file, instead of passing it on
3098 the command line in every compilation.
3099 * Makefile.in (libpath.h): New target.
3100 (feature.o): Depend on libpath.h.
3101 (clean): Delete libpath.h.
3102 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
3103 * feature.c: ... #include "libpath.h" here.
3104 * .cvsignore: Ignore libpath.h.
3106 Don't install the unwashed masses of Guile header files in the
3107 main #include path; put most of them in a subdirectory called
3108 'libguile'. This avoids naming conflicts between Guile header
3109 files and system header files (of which there were a few).
3110 * Makefile.in (pkgincludedir): Deleted.
3111 (innerincludedir): New variable; this and $(includedir) are enough.
3112 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
3113 (installed_h_files): Divide this up. Now this variable lists
3114 those header files which should go into $(includedir) (i.e. appear
3115 directly in the #include path), and ...
3116 (inner_h_files): ... this new variable says which files appear in
3117 a subdirectory, and are referred to as <libguile/mumble.h>.
3118 (h_files): List them both.
3119 (install): Create innerincludedir, not pkgincludedir. Put
3120 the installed_h_files and inner_h_files in their proper places.
3121 (uninstall): Corresponding changes.
3122 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3123 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3124 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
3125 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
3126 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
3127 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
3128 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
3129 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
3130 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3131 vports.h, weaks.h: Find __scm.h in its new location.
3132 * __scm.h: Find scmconfig.h and tags.h in their new locations
3133 (they're both "inner" files).
3135 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
3137 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
3139 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3141 * posix.c: Doc fixes.
3143 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
3145 * socket.c: Don't include a prototype for inet_aton; just use a
3146 K&R style declaration, to avoid warnings but minimize the chance
3147 of conflicts with the system.
3149 On NextStep, <utime.h> doesn't define struct utime, unless we
3150 #define _POSIX_SOURCE before #including it.
3151 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
3152 * acconfig.h: New comment text for above CPP symbol.
3153 * configure.in: Call it.
3154 * posix.c: #define _POSIX_SOURCE if it seems necessary.
3156 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
3158 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
3159 testing for __EMX__.
3161 * posix.c: #include <libc.h>, if it exists.
3163 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
3164 don't even know if the latter exists.
3166 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
3167 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
3168 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
3170 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
3172 (scm_init_posix): Use them when initializing the Scheme constants
3175 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3177 * Makefile.in (libdir, includedir, bindir): Use the
3178 autoconf-supplied values, instead of deriving them ourselves.
3179 (pkgincludedir, datadir, pkgdatadir): New variables.
3180 (install, uninstall): Put the header files in a special
3181 subdirectory, not in the main search path.
3183 * Makefile.in (ALL_CFLAGS): Provide the proper value for
3184 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
3186 * Makefile.in (IMPLPATH): Deleted; never used.
3188 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
3189 on the Tcl/Tk source any more.
3190 (INCLUDE_CFLAGS): Remove references to the above.
3192 * Makefile.in (version.o): Corrected dependencies.
3194 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
3196 * libguile.h: #include "version.h"
3198 * init.c (scm_boot_guile): Call scm_init_version.
3199 * gscm.c (gscm_run_scm): Call scm_init_version.
3201 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
3202 GUILE_VERSION): AC_DEFINE these.
3203 (acconfig.h): #undef the above symbols.
3205 * Makefile.in (libobjs): Add version.o.
3206 (installed_h_files): Add version.h.
3207 (c_files): Add version.c.
3208 (gen_c_files): Add version.x.
3209 (version.o): New rule.
3210 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
3211 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

3219 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
3220 weaks.o): Add version.h to dependency lists.
3221 (markers.o): Remove duplicate rule.
3223 * version.h: New file.
3225 * version.c: New file.
3227 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3229 * symbols.c (scm_strhash): scm_downcase is now a function, not an
3230 array; use it appropriately. Since GCC is quite happy to
3231 subscript functions, it never warned us about this; we should use
3232 -Wpointer-arith in the future. I guess we never tested
3235 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3237 * socket.c: Doc and copyright fixes.
3239 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3241 * debug.c: Fixed and improved gdb support.
3243 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3245 * socket.c: Added declaration of inet_aton to avoid compiler
3246 warning. (Hope this solution is correct.)
3248 * stime.c: Added declaration of ftime. (This is missing in
3251 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
3253 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3255 * Makefile.in (c_files): add strerror.c.
3257 * strerror.c: new file from Emacs' sysdep.c.
3258 maybe configure should also check for sys_errlist.
3260 * configure.in (AC_REPLACE_FUNCS): add strerror.
3262 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3264 * debug.c (scm_init_debug): Added initialization for
3265 scm_evaluator_traps.
3267 * debug.h, debug.c: Various name changes.
3268 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
3269 "debug-options-interface". See commentary in options.c.
3271 * options.h, options.c: Options now have documentation strings.
3272 Also added a long explanatory commentary.
3274 * eval.c, print.h, print.c, read.h, read.c: Modifications to
3277 * gscm.c, init.c, root.c, throw.c: Bug fixes:
3278 last_debug_info_frame is now updated in all cases.
3280 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
3283 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3285 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
3286 Added option STACK_CHECKING.
3288 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3290 * Makefile.in: Added {debug,options,srcprop}.{h,c}
3292 * __scm.h: Removed symbols for debugging support.
3294 * acconfig.h: Added symbols for debugging support.
3296 * configure.in: Added user option for debugging support.
3297 --enable-debug will include the debugging code into libguile.a.
3299 * continuations.c (scm_make_cont): Enlarged the #if 0 around
3300 scm_relocate_chunk_to_heap.
3302 * debug.c: New file: low-level debugging support. It also
3303 includes support for debugging with gdb. (The extensions to gdb
3304 are written by Per Bothner at Cygnus.)
3306 * debug.h: New file: low-level debugging support.
3308 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
3309 argument pairs. Extensive modifications to the debugging
3310 evaluator. Added "SECTION:" commentaries to clarify what happens
3311 when, during double compilation. Renamed EVALIMP --> EVALIM.
3312 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
3313 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
3314 the beginning of the file. New procedure: scm_unmemocopy.
3315 Added some global state variables needed by the debugging
3316 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
3317 check_entry, check_apply, check_exit, debug_options and
3318 evaluator_traps. New acro: undefine.
3320 * eval.h: Renamed EVAL --> XEVAL.
3322 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
3323 --> scm_make_weak_key_hash_table.
3325 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
3326 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
3328 * libguile.h: Conditionally include debug.h
3330 * objprop.c (scm_object_properties, scm_set_object_properties_x):
3331 scm_object_properties shouldn't return handle. `handle' now gets
3332 initialized in scm_set_object_properties_x. scm_object_properties
3333 doesn't any longer create an entry in scm_object_whash.
3335 * options.c: New file: handling of run time options.
3337 * options.h: New file: handling of run time options.
3339 * posix.c (scm_getpgrp): Cast pointer to getpgrp.

3343 * print.h: Defines for print options.
3345 * read.c: New procedure: scm_read_options
3347 * read.h: Defines for reader options.
3349 * root.h: Added scm_source_whash among scm_sys_protects.
3351 * srcprop.c: New file: source properties.
3353 * srcprop.h: New file: source properties.
3355 * throw.c (jbsmob): Jump buffers are now correctly allocated.
3356 (Bug found by A. Green.)
3358 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3360 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3362 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
3364 * libguile.h: #include "objprop.h"; I guess this was forgotten.
3366 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
3367 and should be called by the final client.
3369 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
3371 * gc.h: Use the PROTO macro when declaring functions.
3372 * gc.c: Use the PROTO macro when declaring static functions.
3373 Remove the CPP hair around function definitions.
3375 * gc.c (scm_init_storage): Initialize scm_asyncs.
3377 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
3378 preprocessor symbol; "__scm.h" is where it might get #defined.
3379 * __scm.h: Similar: #include <scmconfig.h> before testing
3382 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
3384 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
3386 * init.c (scm_boot_guile): Add init_func argument; call
3387 (*init_func) instead of calling scm_appinit; it's ucky to
3388 hard-code names for the user's procedures.
3389 * init.h (scm_boot_guile): Adjust declaration.
3391 * __scm.h (PROTO): New macro, for declaring functions with
3394 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
3395 eliminate all the __STDC__ conditionals.
3396 (scm_boot_guile): Add declaration.
3397 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
3398 Remove __STDC__ conditionals around function definitions; the
3399 declarations in init.h will provide the same information, more
3402 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
3403 complain about it in the error message; the error message is
3404 adequate without that note, and there's nothing the user can do
3407 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
3409 * Makefile.in (ancillary): Drop def.sed.
3411 * posix.c (scm_init_posix): Use numeric values, rather than
3412 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
3413 F_OK. The symbols aren't available on some systems, and I'm
3414 pretty sure their values are fixed by common widespread practice.
3415 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
3417 More functions unavailable on some systems.
3418 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
3419 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
3421 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3422 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
3423 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
3424 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
3425 stub that signals an error as the #else.
3427 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
3429 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
3431 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
3433 * unif.c: include ramap.h.
3435 * read.c (endif): case_insensative_p renamed case_insensitive_p.
3437 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
3439 * ports.c: include sys/ioctl.h.
3441 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
3443 * configure.in: check for sys/ioctl.h.
3445 * ports.c: include <malloc.h> not "malloc.h".
3447 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3449 * fports.c: remove ttyname and tmpnam declarations.
3451 * posix.c: fewer ttyname declarations.
3453 * fports.c: include <string.h> not "string.h".
3455 * init.c, ioext.c: include string.h and unistd.h.
3457 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3459 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
3460 genio.c, simpos.c, vports.c: include string.h.
3462 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
3464 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
3466 (scm_addr_buffer_size): change type from scm_sizet to int.
3467 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
3468 from scm_sizet to int.
3470 * error.c: include unistd.h.
3472 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
3475 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
3477 * __scm.hd, def.sed: deleted.
3479 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
3481 Changes for NeXT, suggested by Robert Brown.
3482 * configure.in: Call AC_TYPE_MODE_T.
3483 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
3484 NeXT. Put header file list in alphabetical order.
3485 * configure, scmconfig.h.in: Regenerated.
3486 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
3488 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
3491 * acconfig.h: New file, providing documentation for the CPP
3492 symbols defined in configure.in
3493 * acconfig-1.5.h: Removed; superceded by the above.
3495 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
3497 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
3499 * fports.c (scm_open_file): don't return #f, throw error.
3501 * ioext.c (fileno): renamed from %fileno.
3502 (soft-fileno): deleted.
3504 * ports.c (scm_port_revealed): don't need to check for -1 from
3506 (scm_set_port_revealed_x): return unspecified, not #f.
3508 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
3510 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
3512 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
3514 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
3516 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3518 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
3519 This is necessary on Ultrix, and doesn't hurt portability.
3521 * Makefile.in (dist-dir): New target, implementing a new dist system.
3522 (installed_h_files): Put in alphabetical order.
3523 Remove duplicate entries for markers.h and unif.h.
3524 (c_files): Remove duplicate entries for markers.c.
3525 (ancillary): Renamed from anillery; all uses changed. Remove
3526 PLUGIN; it's a directory, and needs special treatment in dist-dir.
3527 Remove all the ../doc/* files; doc/Makefile.in handles that.
3529 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3531 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3532 every if must have an else, or else the whole command has a
3533 non-zero exit code whenever the if's condition is false.
3535 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
3537 * posix.c: include string.h.
3539 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3541 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
3544 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
3545 Remove leading % from scheme names.
3546 Do not return error values, call SCM_SYSERROR or similar.
3548 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
3550 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
3552 * struct.c (scm_init_struct): new file.
3554 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
3556 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
3557 (scm_list_head): added list-head for rapidly chopping argument
3558 lists off of longer lists (and similar).

3562 * objprop.c (scm_object_property): assq the cdr of the whash
3563 handle for obj, not the handle itself.
3565 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
3567 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
3568 weak hash tables last of all marking to avoid an obscure gc bug.
3569 WARNING: circular lists stored in a weak hash table will hose us.
3571 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
3573 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
3574 new functions similar to scm_substring_move_left_x and
3575 scm_substring_move_right_x.
3577 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
3579 * init.c (scm_boot_guile): prevent gc with scm_block_gc not

3584 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
3586 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
3588 * strports.c (scm_strprint_obj): convenience function. C for
3589 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
3591 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
3592 removed to a separate library
3594 * init.c (scm_boot_guile): copied from guile-tcl.c.
3595 Initialization specific to tcl interpreters removed.
3597 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
3599 * ports.c (scm_ports_prehistory): size malloced here doesn't
3600 matter so long as it is non-0 (got rid of "* 4").
3602 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3604 * gscm.h: gscm_mkarray eliminated (presumably was not being used
3605 since its definition was bogus).
3607 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
3609 * mallocs.[ch]: back again (for rx at least).
3611 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
3613 * ports.c: removed functions relating to the mapping between ports
3614 and descriptors. (That stuff is unix-specific and should be collected
3615 in a separate library).
3617 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
3618 (Tom Mckay@avanticorp.com)
3620 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
3622 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3623 handled correctly (SCM_FREEP was applied to them) -- test for
3624 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
3625 being overwritten with #f. (brown@grettir.bibliotech.com)
3627 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
3629 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

3632 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
3634 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak

3644 Generalized assoc and hash-table functions.
3645 Factored pairs.c into multiple files.
3647 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
3649 * gscm.c (gscm_run_scm): got rid of objprop.
3651 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
3653 * genio.c (scm_getc):
3654 NOTE: fgetc may not be interruptable.
3656 * procprop.c (scm_stand_in_scm_proc):
3657 NOTE: don't use a alist here.
3658 (scm_set_procedure_properties_x): fix type checking throughout this file.
3660 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
3662 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
3663 after freeing part of the port table.

3667 * strports.c (scm_mkstrport):
3668 * vports.c (scm_make_soft_port): allocate a port table entry
3669 (possibly triggering gc) before setting the tag of the corresponding
3672 * pairs.c (scm_delq_x): never throw an error.
3674 * vectors.c (scm_make_vector): made the default vector fill argument
3675 into '() (much more useful than the previous value, "#unspecified")
3677 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
3679 * ports.c (scm_add_to_port_table): Added fields
3680 to port table entries: file_name, line_num, col.
3681 Update these in open_file, gen_getc and gen_ungetc.
3682 Added procedures to access those fields.
3684 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
3686 * procs.c (scm_make_subr_opt): new entry point for making
3689 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
3691 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
3693 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
3695 * numbers.c (scm_exact_p): This function no longer
3696 implements "integer?".

3700 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
3701 (scm_gc_stats): return an assoc of useful data. Replaces "room"
3702 and the stats reporting formerlly built into repl.

3705 GC statistics keeping moved to gc.c.
3706 Other statistics keeping can be done from Scheme.
3707 REPLS are now written in Scheme.

3714 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
3716 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
3718 * feature.c (scm_compiled_library_path): moved here from repl.c.
3719 This file is for stuff relating specifically to Scheme libraries
3722 * eval.c (scm_m_define): don't give warning about redefinition, don't
3725 NOTE: this should throw a resumable exception with parameters --
3726 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
3728 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
3730 * error.c: scm_warn eliminated.

3742 between the call to procedurep and use.
3744 * error.c (scm_everr):
3746 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
3749 * strports.c: don't reveal the port's string to the caller
3750 because it changes size.
3752 (stputc stwrite): check/change the strings length with interrupts
3755 * objprop.c (scm_set_object_property_x &c): use the generic
3756 hashing functions and be threadsafe.
3758 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
3759 (per suggestion jaffer@gnu.ai.mit.edu).
3761 * mbstrings.c (scm_multi_byte_string): guard against argument list
3764 * strings.c (scm_make_string): loop cleanup
3766 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer
3769 * weaks.c (scm_weak_vector): guard against argument list
3772 * variable.c (scm_builtin_variable): check for/make a built-in
3775 * vectors.c (scm_vector): while filling the new array,
3776 guard against a list of fill elements that grows after
3777 the vector is allocated.
3779 * hashtab.c -- new file: general hash table
3780 functions. hash, hashq, hashv, hashx.
3782 * tags.h: made wvect an option bit of vector.

3786 * symbols.c: made the basic symbol table operations atomic.
3788 * root.c &c.: collected stack-specific global state.
3789 linum/colnum etc *should* be port-specific state.
3791 * struct.c (scm_init_struct): init the first struct type during
3792 initialization to fix a race condition.
3794 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
3795 object, not in a global.
3796 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
3798 * throw.c (_scm_throw): Pass throwval on the stack, not in a global
3799 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)

3813 * async.c: New support for interrupt handlers.
3815 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
3817 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
3818 set the multi_byte flag correctly in symbols. This is wrong.
3819 intern_obbary_soft and msymbolize should take an extra parameter.
3820 Also, weird multibyte symbols don't print correctly.
3821 The weird symbol syntax is also a bit bogus (emacs doesn't quite
3824 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
3826 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
3827 use the system symhash. == #t means create an uninterned symbol.
3829 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
3831 * strings.c (scm_make_shared_substring): build'em.
3832 It might better to keep a table of these and use one
3833 less cons-pair per shared-substring.
3835 Tue Feb 6 17:45:21 1996 Tom Lord <lord@beehive>
3837 * strings.c (scm_string_shared_substring): create shared
