5 process without unwinding the stack.
7 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
9 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
10 argument and logior its components together, so the user doesn't
11 have to do this explicitly. Also, if regexp/basic is supplied, then
12 turn off REG_EXTENDED.
13 (scm_init_regex_posix): New regexp/basic symbol.
14 (REG_BASIC): #define this if it is not already present.
16 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
18 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
19 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
20 (CLEANFILES): New target, clean versiondat.h, libpath.h.
21 (DISTCLEANFILES): New target, clean *.x.
22 * Makefile.in: Regenerated.

30 * Makefile.in: Regenerated.
32 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
33 flag; I don't think we support it.
34 (scm_make_regexp): Make sure the user doesn't pass the
37 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
39 (scm_init_regex_posix): Define constants for the REG_mumble flags;
40 name them according to the SCSH convention: regexp/mumble.
42 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
44 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
46 * Makefile.am (libpath.h): Include the values of all the standard
47 Makefile directory variables. Print a message, but don't print
49 (versiondat.h): Print a message, but don't print all the commands.
50 * load.c: #include "alist.h".
51 (init_build_info): New function.
52 (scm_init_load): Call it.
53 * Makefile.in: Regenerated.
55 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
57 * root.c: Establish a reliable catch-all handler for the new root.
58 After all the Scheme handler function might signal an error too,
59 and we don't want to lose that.
60 (cwdr_inner_body): Renamed from cwdr_body.
61 (cwdr_outer_body): New function, to establish the user's handler,
62 and pass control to cwdr_inner_body.
63 (cwdr): Establish the reliable catch-all handler here, and pass
64 control to cwdr_outer_body.
65 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
66 the user's handler through to cwdr_outer_body.
67 * throw.c (scm_handle_by_message): Move guts into....
68 (handler_message): New static function.
69 (scm_handle_by_message_noexit): New function.
70 * throw.h (scm_handle_by_message_noexit): New prototype.
72 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
73 across this. Only works on GCC. Otherwise, we hope for the best.
74 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
75 the feeling that real thread systems will not need this...
77 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
79 Try to detect when people are using one version of libguile and a
80 different version of ice-9. People have been skewing things and
81 sending in bug reports.
82 * Makefile.am (versiondat.h): New file to generate.
83 * version.c: #include "versiondat.h", to get version info.
84 (scm_libguile_config_stamp): New function.
85 * script.c: #include "version.h".
86 (scm_compile_switches): Call scm_version to get version number.
87 * scmconfig.h.in, Makefile.in: Regenerated.
88 * Makefile.in: Regenerated.
90 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
91 primitive definitions under their Scheme names.
93 * Makefile.am (libguile_la_LDFLAGS): Update library version to
94 1:2. Helps avoid confusion between installed and uninstalled libs.
96 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
99 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
100 backslash from definition; this should be used like: GDB_INTERFACE;
102 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
104 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
105 new port unbuffered until its stream has been set.
107 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
109 * ports.h: new prototype.
110 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
112 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
114 Make things compile neatly under Sun's C compiler.
115 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
116 * extchrs.c (xmbtowc): Make the second arg a normal char, not
117 unsigned, because that's what the ANSI function takes.
118 * extchrs.h (xmbtowc): Corresponding change to prototype.
119 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
121 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
122 argument plain char *.
123 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
125 * tag.c (scm_tag): Remove unreachable statement.
126 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
127 top of the word, it should be unsigned.
129 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
130 is defined, to avoid warnings; it's only used in the
131 conflict-checking code. Which might go away anyway.
132 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
133 conditionals; put the label definition in an #if too, to stifle
136 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
137 ChangeLog-threads in the distribution.
138 * Makefile.in: Regenerated.
140 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
142 * guile-snarf.in: Changed regexp to support CPPs that insert
143 whitespace between lexical tokens (which munges the `%%%' snarf
146 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
148 * load.c (scm_init_load_path): Append $(datadir)/guile to
149 %load-path, so modules do not have to be installed in Guile's
150 current version directory.
152 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
154 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
155 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
156 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
157 call the sysdep functions with deferred ints.
158 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
159 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
160 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
163 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
166 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
168 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
170 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
172 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
175 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
177 * eval.c (scm_lookupcar1): New procedure to cope with a race
178 condition during lookup (when using threads).
179 (scm_lookupcar): Implement in terms of scm_lookupcar1.
180 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
183 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
185 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
186 supplied. (Change from Tim Pierce.)
188 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
190 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
191 23:47:01 1997" changelog: Slots are now initialized with `#f' by
192 default and not `()'. `#f' is the canonical non-value in Scheme,
195 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
197 * struct.c (struct_printer): New variable that holds a handle on
198 the Scheme variable *struct-printer*. This variable can be set by
199 Scheme code to override the printing of structures.
200 (scm_print_struct): If struct_printer is set, call it. If it is
201 not set, or returns #f, print the structure in the old fashion.
202 Include "eval.h" for scm_apply.
204 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
206 * struct.c (scm_struct_ref, scm_struct_set_x): Use
207 scm_struct_i_n_words to get the number of fields, not
208 -scm_struct_n_extra_words.
210 On the route to fancier struct printing:
211 * struct.c (scm_print_struct): New function to print a structure.
212 Include "genio.h" to support it. This function doesn't do
213 anything interesting right now, but I think it should be here
215 * struct.h: Include "print.h" and add prototype for
217 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
218 print structures ourself.
220 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
222 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
223 before applying the handler in case it doesn't return.
225 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
227 * scmsigs.h, async.h: updated.
229 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
232 * posix.c (scm_uname): interpret only negative values as an error.
233 Solaris normally returns a positive value.
235 * script.c (scm_compile_shell_switches): if we are not going into
236 an interactive repl, set scm_mask_ints to zero so that asyncs can
239 * simpos.c (scm_system): don't ignore/unignore signals around
242 * posix.c (scm_open_pipe): don't ignore/unignore signals around
245 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
246 done in boot-9.scm instead.
248 * scmsigs.c, async.c: Major rewriting of signal handling code.
249 (scm_sigaction): new procedure.
250 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
252 (scm_raise): return unspecified, throw error on failure.
254 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
256 * regex-posix.c (scm_init_regex_posix): Register the "regex"
257 feature, to help boot-9.scm decide whether to import the regex
260 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
262 * eval.c: Include scmconfig.h at the beginning of the file so that
263 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
266 * regex-posix.c: #include "_scm.h" before conditionally #including
267 <regex.h>; the former defines HAVE_REGCOMP.
269 * regex-posix.c: #include <regex.h> conditionally, so the file is
270 CPP'able (for dependency scanning) even on systems that don't have
273 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
275 Add new R4RS-compliant syntax for keywords.
276 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
277 regardless of the setting of the `keywords' read option.
278 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
279 can be re-read no matter what the setting of the `keywords' read
282 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
284 Add support for POSIX regular expressions.
286 * regex-posix.c, regex-posix.h: New files. (Some code
287 is taken liberally from rx/rgx.c in the old Guile dist.)
289 * init.c: Include regex-posix.h.
290 (scm_boot_guile_1): Call scm_init_regex_posix.
292 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
293 Add regex-posix.[ch] sources.
294 * Makefile.in: Regenerated.
296 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
297 to do this automatically? It didn't for me, bleh.)
299 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
301 * fports.c (print_pipe_port): New function.
302 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
303 latter doesn't even take the right arguments.
305 * Makefile.am: Increment shared lib revision number. I think
306 sometimes the uninstalled Guile finds the installed shared lib;
307 Gord says doing this might help. As things turned out, I can't
309 * Makefile.in: Regenerated.
311 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
312 passing it as the closure argument to scm_boot_guile. (Bill
315 * ports.c (print_void_port, putc_void_port, puts_void_port,
316 write_void_port, flush_void_port, getc_void_port, close_void_port,
317 noop0): Use ANSI prototypes instead of K&R declarations, so the
318 initialization of void_port_ptob gets aggressively type-checked.
319 Fix arguments of print_void_port and write_void_port. (Bill

353 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
355 * script.c (scm_find_executable): Use prototype-style definition
356 here; apparently it's not quite right to have const in a prototype
357 and then use a K&R declaration. I wonder if stuff like this will
358 go away if we compile with -Wrequire-prototypes, or whatever that
359 is... (Bernard URBAN)
361 * scmhob.h: New text from Bernard URBAN.
363 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
365 * script.c: Don't #define const on hpux. Configure takes care of
366 this. (Thanks to Larry Schwimmer.)
368 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
369 decide whether to #include <unistd.h>, instead of listing a bunch
370 of systems. Don't #include stdio twice. Removed dyked-out
371 definition of scm_find_impl_file.
373 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
375 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
376 library version info to 1:0.
377 * Makefile.in: Regenerated.

384 throw.c: Update copyright years; these files have been worked on
385 significantly in 1997, but only had copyright years for 1996.
386 Also, change name of copyright holder on some from Mikael
387 Djurfeldt to Free Software Foundation; he has signed papers
388 assigning the changes to the FSF.
390 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
391 reason not to give the user the option.
393 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
394 Return #f on end-of-file when scanning table (i.e. when called
395 with no arguments). Try to catch errors, when we can.
396 * posix.c (scm_getgrgid, scm_getpwuid): Same.
398 * script.h (scm_shell_usage, scm_compile_shell_switches): New
399 external declarations. These are useful.
401 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
403 * posix.c: don't include <sys/select.h> or define macros for
404 select, since they were not used in this file.
406 * filesys.c (scm_select): make the fifth parameter microseconds,
407 not milliseconds. let the fourth parameter be either a real value
408 or an integer or #f. The first, second and third arguments can
409 now be vectors: the type of the corresponding return set will be
411 (set_element, get_element): new static procedures.
413 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
415 * strports.c (scm_eval_string): New function.
416 (scm_eval_0str): Trivially re-implemented in terms of
418 * strports.h (scm_eval_string): New extern decl.
420 * net_db.c (h_errno): Add extern decl for this.
422 * fports.c (local_pclose): New function.
423 (scm_pipob): Use it in the initializer here.
426 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
427 Use a meaningful error message when signalling an error. For
428 this, scm_gethost must check h_errno rather than errno.
430 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
432 * Makefile.in: Regenerated, using automake-1.1p.
434 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
436 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
439 * script.c (scm_compile_shell_switches): don't append (quit) if
441 (scm_shell): call scm_exit_status and exit on the result of the
444 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
446 Ensure that shared substrings are handled properly when passed to
447 a system call or other foreign function. Many thanks to Tim
449 * symbols.h (SCM_COERCE_SUBSTR): new macro.
450 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
451 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
452 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

467 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
469 * error.c (scm_error): Add newline to error message.

473 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
475 * dynl-shl.c: Completely replaced with new code from Bernard
478 * script.c (scm_ice_9_already_loaded): New variable.
479 (scm_compile_shell_switches): Use it.
481 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
483 * filesys.c (scm_input_waiting_p): add missing third argument to
486 * stime.c (scm_localtime): copy the result of localtime before

495 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
497 * Makefile.am (check-local): New target, which causes 'make check'
498 to run gh_test_c and gh_test_repl, with some trivial input.
499 * Makefile.in: Rgnrtd.
501 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
503 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
506 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
508 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
509 sure how this was supposed to work.
510 (scm_async_click): don't send SCM_TICK_SIGNAL.
511 (scm_init_async): don't initialize %tick-thunk.
513 * the following change doesn't affect the Scheme interface:
514 gc-thunk is called at the end of garbage collection. however it's
515 no longer implemented by pretending it's a signal.
517 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
518 system async corresponding to scm_gc_thunk.
519 * async.h: declare scm_gc_async.
520 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
521 gc-thunk directly, instead of going through a signal handler.
522 (scm_gc_async): new variable, points to the GC system-async.
523 (scm_init_async): save the GC async as scm_gc_async instead
524 of using system_signal_asyncs.
525 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
527 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
529 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
530 Don't screw up if we're interrupted.
531 * Makefile.in: Regeneradet.
533 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
535 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
537 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
538 we're not using AM_INIT_GUILE_MODULE any more.
539 * Makefile.in: Reneregated.
541 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
543 Functions for finding variable bindings, grace à Tim Pierce.
544 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
545 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
547 Get 'make dist' to work again.
548 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
549 * Makefile.in: Regenerated, like a surry without a fringe on top.
551 Changes for reduced Guile distribution: one configure script,
553 * configure.in, configure: Removed.
554 * acconfig.h, acinclude.m4: Moved to parent directory, where the
555 real configure script lives.
556 * Makefile.in, scmconfig.h.in: Regenerated.
558 * init.c: #include "script.h", to get prototype for script.c's
561 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
563 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
564 scm_must_malloc, not raw malloc.
566 * script.c (scm_compile_shell_switches): Dyke out debugging output
569 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
571 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
573 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
574 system has them. Hope this is safe. Previously
575 sys/timeb.h was included if HAVE_FTIME was defined or if
576 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
577 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
579 * ioext.c (scm_setfileno): add missing third argument to
582 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
584 * eq.c (scm_equal_p): Correctly compare strings of different
585 varieties. (Thanks to Tim Pierce.)
587 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
589 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
590 #! block comment must occur on a line all by itself.
592 Move most of the guts of shell command processing into libguile,
593 so guile.c can be very small (and eventuallly auto-generated. (I
594 mean, generated mechanically, not self-generated. Hmm.))
595 * guile.c, script.c, script.h: New source files.
596 * init.c (scm_boot_guile_1): Call scm_init_script.
597 * libguile.h: #include "script.h".
598 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
599 targets, for new executable.
600 (libguile_la_SOURCES): Mention script.c.
601 (modinclude_HEADERS): Add script.h.
602 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
603 not dynamic linking is enabled. This is because we're generating
604 executables now. Move CY_AC_WITH_THREADS call after those, so the
605 values of cy_cv_threads_libs captures the libs chosen above.
606 * Makefile.in, configure, aclocal.m4: Regenerated.
608 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
609 We don't maintain this interface any more, and it just confuses
612 * alloca.c: #include <scmconfig.h>, not <config.h>.
613 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
614 it'll get included in disties.
616 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
618 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
619 be distributed, because they confuse people.
620 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
622 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
624 * configure.in: check for presence of gethostent (not present on
626 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
627 * configure, scmconfig.h.in: Regenerated.
629 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
631 * backtrace.c (scm_backtrace): Split message string across
632 newlines properly. GCC is more tolerant of this than other

637 Merge threads directory into libguile.
638 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,

643 (modinclude_HEADERS): Add threads.h, coop-defs.h.
644 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
645 coop-threads.c.cygnus, coop-threads.h.cygnus.
646 * configure.in: If we're using threads, include threads.o in
648 * _scm.h, libguile.h: threads.h lives in this directory now.
649 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
650 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
651 currently used, but brought along for information's sake.
652 * ChangeLog-threads: log from old 'threads' directory.
653 * Makefile.in, configure: Rebuilt.
655 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
657 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not

662 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
664 Merge GH interface library into libguile.
665 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
666 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
667 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
668 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
670 (EXTRA_libguile_la_SOURCES): ... here.
671 (pkginclude_HEADERS): Add variable, to get gh.h installed.
672 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
673 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
674 New variables, describing how to build the gh test programs.
675 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
676 build the test programs, and we probably should have been linking
677 libguile.la against them all along, to support AIX shared libs.
678 Add cflags for threads to CFLAGS; add libs for threads to new
679 variable THREAD_LIBS, used in Makefile.am.
680 * ChangeLog-gh: log from old `gh' subdirectory.
681 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
683 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
685 * acconfig.h: Undo change of Apr 9; including the definition of
686 PACKAGE in the guile headers conflicts with applications' own
688 * scmconfig.h.in: Regenerated.
690 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

699 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
701 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
702 have S_IFSOCK. This is the case under Ultrix.
704 * posix.c (scm_status_exit_val, scm_status_exit_val,
705 scm_status_term_sig, scm_status_stop_sig): Modified to work with
706 Ultrix versions of WIFSTOPPED, etc., which assume that their
707 arguments are lvalues (hmm).
709 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
713 * throw.c: Doc fixes; rearranged.
715 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
717 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
719 * acconfig.h: Added entry for PACKAGE.
720 * scmconfig.h.in: Regenerated.
722 Changes to work with automake-1.1n, which has better libtool support.
723 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
724 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
726 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
728 * Makefile.in: Rebuild.

732 * stime.c (scm_mktime): take an optional zone argument.
733 (scm_localtime): check putenv return value.
734 (scm_strftime, scm_strptime): moved from posix.c. move #include
736 stime.h, posix.h: update prototypes.
737 (bdtime2c, setzone, restorezone): new static procedures.
738 (scm_mktime, scm_strftime): use them.
739 (scm_strftime): don't call mktime before strftime. Use
740 filltime for return value.
741 (filltime): convert NULL zname to #f.
742 (scm_strptime): return a count of characters consumed, not
743 the remaining string.
745 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
747 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.

754 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
756 * stime.c (scm_init_stime): don't define ticks/sec.
757 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
758 return value problem and is still portable.)
760 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
762 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
763 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
764 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
765 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
766 cpp_err_symbols.c): Corresponding changes.
767 * Makefile.in: Regenerated.
769 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
771 * posix.c (scm_putenv): don't check HAVE_PUTENV.
772 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
773 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
774 * putenv.c: new file, from sh-utils 1.12.
776 * posix.c (scm_environ): use malloc in place of scm_must_malloc
777 since allocation isn't for Scheme objects.
778 (scm_putenv): copy strings before placing in the environment.
780 * stime.c (scm_current_time): throw an error if time returns -1,
781 instead of returning #f.
782 (scm_get_internal_real_time, scm_get_internal_real_time): use
783 scm_long2num for return value instead of SCM_MAKINUM.
785 * stime.h: prototypes updated.
787 * stime.c (scm_time_in_msec): apparently unused, deleted.
789 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
791 * configure.in: check for gettimeofday.
793 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
794 which may be more usefully portable than a gettimeofday interface.
796 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
798 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
800 * Makefile.in: Regenerated.
802 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>

811 * posix.c (scm_mknod): split the mode argument into type and perms
812 arguments, like the extra fields returned by stat.
814 * fports.c (scm_pipob): set the close, free and print procedures.
815 (scm_close_pipe): new procedure.
817 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,

820 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
822 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
823 wan't defined. Don't include fd.h.
825 * Previously fd.h was regenerated whenever configure was run,
826 forcing a couple of files to be recompiled.
828 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
829 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
830 Check for _fileno as well as _file.
832 * ioext.c: don't fd.h.
833 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
836 * Change the stratigy for getting information about errno
837 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
838 generating lists of symbols during the build process, which will
839 not always work, include comprehensive lists in the distribution.
840 To help keep the lists up to date, the "check_signals" and
841 "check_errnos" make targets can be used.
843 * configure.in: don't check for a command to extract errno codes.
844 * Makefile.am: update file lists, remove errnos.list and errnos.c
845 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
846 check_errnos targets.
847 (CLEANFILES): remove errnos.c and errnos.list, add
848 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
849 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
850 * errnos.default: deleted.

853 * cpp_err_symbols, cpp_sig_symbols: new files.
854 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
855 * error.c (scm_init_error): #include cpp_err_symbols instead of
857 * posix.c (scm_init_posix): don't intern signal symbols. #include
860 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
862 * strop.c (scm_i_index): allow the lower bound to be equal to the
863 length of the string, so a null string doesn't always give an error.
865 * posix.h: new prototypes.
866 * posix.c (scm_status_exit_val, scm_status_term_sig,
867 scm_status_stop_sig): new functions, as in scsh. They break down
868 process status values as returned by waitpid.
870 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
872 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
873 configure doesn't know about it.
875 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
877 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
879 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
880 which defines C variables with global linkage.
882 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
884 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
887 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
889 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
890 has time to check why this doesn't work well with continuations.
892 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
894 * Fix shell syntax error; some shells won't tolerate
895 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
897 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
899 * posix.c (scm_uname): throw an error if uname fails instead
902 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
904 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
907 * async.c (scm_ints_disabled): definition moved from error.c.

911 * acconfig.h: Removed PACKAGE.
913 * scmconfig.h.in: Regenerated.
915 * snarf.h: g++ says it's non-portable not to specify the first
916 argument in a varargs declaration. I introduced the first
917 argument by using preprocessor conditionals.
919 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
921 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
922 (scm_freopen): use RO string macros for filename and modes.
923 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
925 * posix.c (scm_getgrgid): simplify conversion of name to C string.
926 (scm_mknod): use RO string macros for path.
928 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
929 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
931 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
932 use SCM_ROSTRINGP and SCM_ROCHARS.

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

948 * backtrace.c (scm_display_error_message): don't segv if message
951 * error.h: prototype for scm_error_scm.
953 * error.c (scm_error_scm): new procedure, reimplements scm-error
954 in C and uses scm_error.
956 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
958 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
959 pointer to the Scheme variable read-hash-procedures and intern it
960 in scm_init_read. Modify scm_read_hash_extend and
961 scm_get_hash_procedure to use the pointer.
963 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
965 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
966 (SCM_KEYWORD_STYLE): defined.
968 * read.c (scm_read_opts): add a keywords option. This isn't a
969 boolean option, in case someone wants to add support for DSSSL
971 Setup scm_keyword_prefix symbol.
972 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
974 I've left keyword support disabled by default, since it doesn't
975 seem to break the module system and it gives R4RS standard behaviour.
976 It can be reactivated with (read-set! keywords 'prefix).
978 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
980 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
981 before constructing arbiter.
983 * eval.c (scm_m_define): Bugfix: Check that the object is a
984 closure before setting the procedure property!
986 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
988 * ports.c: Removed `ungetc-char-ready?'.
990 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
992 * read.c (scm_init_read): intitialise scm_read_hash_procedures
993 (idea from Mikael: make it a pair so scm_permanent object only
995 (scm_read_hash_extend): don't call scm_permanent_object.
996 (ideas from Mikael): if chr is already in the list, replace its
997 procedure instead of appending it again. If proc is #f, remove
999 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
1001 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
1003 * gdbint.c (gdb_read): update scm_lreadr usage.
1005 * load.h: update prototypes.
1007 * load.c (scm_primitive_load, scm_read_and_eval_x,
1008 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
1010 * read.h: add prototype for scm_read_hash_extend. Change args for
1013 * read.c (scm_read_hash_procedures): new variable.
1014 (scm_read_hash_extend): new procedure.
1015 (scm_get_hash_procedure): new procedure.
1016 (scm_lreadr): use scm_get_hash_procedure instead of an argument
1017 for extended # processing.
1018 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
1019 scm_read_token): remove case_i, sharp arguments. Change callers.
1021 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
1023 * read.h (SCM_N_READ_OPTIONS): increase to 3.
1024 (SCM_CASE_INSENSITIVE_P): define.
1026 * read.c: add case-insensitive option to scm_read_opts.
1027 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
1028 to determine whether to convert symbol case.
1029 (default_case_i): definition removed.
1030 * read.c (scm_read_token): if case_i, downcase ic before doing
1033 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1035 * configure.in: Added configuration option `guile-debug'.
1036 Configure with --enable-guile-debug if you want a bunch of extra
1037 functions used for debugging when developing Guile.
1039 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
1041 * procs.c (make-cclo): New undocumented debugging procedure: Make
1042 compiled closure with internal procedure PROC and length LENGTH.
1043 Only compiled if GUILE_DEBUG is defined.
1045 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
1047 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
1049 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
1051 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
1052 with 3 or more args internally to the evaluator.
1054 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1056 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
1057 with 3 or more args internally to the evaluator. This is mainly
1058 because we don't want to pass entry and exit points of the
1059 debug support twice, but it also seems to increase the speed of
1060 the evaluator for such calls (e. g. (+ 1 2 3)).
1062 * backtrace.c (scm_display_application): New procedure:
1063 display-application; Set fancy printing parameters individually
1064 for different types of display (backtrace, error, application).
1065 (These should of course be customizable!)
1067 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
1068 clear the CHECK-flags.
1070 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1072 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
1074 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1076 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
1077 from pairs with a GLOC in the car.
1079 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
1080 otherwise `symbol-hash' will behave badly.
1081 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
1082 we get segmentation fault!
1084 * symbols.c: Added #include "weaks.h". New functions:
1085 `builtin-bindings' and `builtin-weak-bindings'. (These will be
1086 moved to an extraneous library when we split libguile.)
1088 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1090 * filesys.c (scm_stat): stat now takes fport arguments too as
1091 documented in the manual.
1093 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1095 * debug.c (scm_single_step): Bugfix: Call continuation with
1096 scm_call_continuation instead of throwing to it.
1098 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1100 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
1101 argument wasn't declared to be optional.
1103 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1105 * stime.c (scm_init_stime): Add feature "current-time".
1107 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
1109 * throw.h: prototype for scm_exit_status.
1110 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
1111 args to derive an exit status. Allows (quit) to work from a
1113 (scm_exit_status): new function.
1116 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1118 * eval.c (scm_deval): Removed some old code.
1119 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
1121 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
1124 * symbols.c (msymbolize): Bugfix: Must initialize property list to
1127 * procs.c: Introduce the existent C function scm_thunk_p at the
1128 Scheme level as well.
1130 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1132 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
1133 used from C to easily lookup the value of a symbol in the current
1136 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1138 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
1139 scm_init_unif in this file. This will also fix a previous problem
1142 * configure.in: Added AM_MAINTAINER_MODE
1144 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1146 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
1149 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1151 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
1152 source files that are not always included in libguile but should
1153 have their dependencies calculated by automake. This variable is
1154 recognized by automake, no further magic is needed.
1155 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
1156 to deal exclusively with *.lo files, as it seems. The *.o files
1157 are built automatically when the corresponding *.lo file gets
1160 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
1162 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
1165 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
1167 * unif.c (scm_array_set_x): minor change to argument error checking.
1169 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
1171 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
1172 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
1173 They should only be included in the library at configure.in's
1175 (libguile_la_LDADD): Include the appropriate .lo files here.
1176 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
1177 so we know when to build them (and their .lo bretheren).
1178 * configure.in (LIBLOBJS): New substituted variable. We let
1179 configure decide which .o files to include in LIBOBJS, and then
1180 put the corresponding list of .lo files in LIBLOBJS. The latter
1181 is what we pass to libtool.
1182 * Makefile.in, configure: regenerated.
1184 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
1186 * symbols.c (scm_sysintern0): New function. Contains the core of
1187 old scm_sysintern but doesn't take a second value argument.
1188 (scm_sysintern): Now uses scm_sysintern0.
1189 (scm_sysintern_no_module_lookup): Renamed to
1190 scm_sysintern0_no_module_lookup and doesn't take a second value
1191 argument any longer.
1193 * symbols.h (scm_sysintern0: Added declaration.
1195 * options.c (scm_init_opts): Use scm_sysintern0 instead of
1196 scm_sysintern when interning option keys. Otherwise we risk
1197 destroying the values of already interned variables.
1199 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
1200 scheme-level boolean (use SCM_NFALSEP).
1202 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
1204 (scm_backtrace): New function. (C version of old function from
1205 boot-9.scm) Motivation: Make it possible to display backtraces
1206 without depending on boot-9.scm. (I'm uncertain if this
1207 motivation is good enough...)
1209 * root.h (scm_root_state): Add member the_last_stack_var.
1210 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
1212 * root.c (mark_root): Mark scm_the_last_stack_var.
1214 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
1217 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
1219 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
1220 1. mark_lazy_catch didn't mark the smob.
1221 2. Both functions above have standard variants:
1222 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
1223 free_lazy_catch --> scm_free0.
1225 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
1227 * throw.c (scm_internal_lazy_catch): New function.
1228 (scm_lazy_catch): Rewritten to use it.
1229 (scm_ithrow): Handle the new lazy catch representation.
1230 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
1231 that doesn't have a jmpbuf is a lazy catch clause.
1232 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
1233 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
1234 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
1236 (scm_init_throw): Register the new lazy-catch smob type.
1237 * throw.h (scm_internal_lazy_catch): decl for new function.
1239 * throw.c (scm_internal_catch): Doc fixes.
1241 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
1242 configure.in. Including this might cause problems if applications
1243 that link against libguile include their own copies of alloca, but
1244 if they're using autoconf, they should be adding libguile to LIBS
1245 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
1246 the copy in libguile, and things will be okay. (I think.)
1248 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1250 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
1252 strop.h: move prototypes too.
1254 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
1256 * posix.c (scm_init_posix): don't intern EINTR since it's now done
1259 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
1260 etc. I deleted them from filesys.c long ago, but didn't
1261 notice they were here too (although ineffective since
1262 sys/stat.h wasn't included).
1264 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
1266 * eval.c: Don't define alloca in GCC case. gcc will automatically
1267 use __builtin_alloca if appropriate.
1269 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1271 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
1272 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
1273 that values of automatic variables are preserved. See comments
1274 for safe_setjmp for details.
1276 Change from Thomas Morgan:
1277 * variable.c: Include eq.h.
1278 (var_equal): New function.
1279 (variable_smob): Use var_equal as the discriminator for variables.
1281 * throw.c (s_throw): Remove extraneous declaration.
1283 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
1284 * eval.c: Add necessary CPP cruft to support that.
1285 * configure, Makefile.in, scmconfig.h.in: regenerated.
1287 Change from Thomas Morgan:
1288 * procprop.c (scm_procedure_properties): Convert the Scheme
1289 boolean returned by scm_procedure_p into a C boolean before using
1290 it as a condition for SCM_ASSERT.
1291 (scm_procedure_property): Likewise.
1293 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
1294 indications of Unixness.
1297 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
1299 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
1301 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
1303 * read.c (scm_lreadr): use scm_misc_error to improve one of the
1304 "unknown # object" error messages.
1306 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
1307 (scm_i_index) and declare it static. Add a 'direction' argument
1308 to indicate what way the search should go.
1309 (scm_i_index): throw out-of-range error instead of wrong-type-arg
1311 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
1312 strop.h: remove scm_i_index, scm_i_rindex prototypes.
1314 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1316 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
1318 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
1319 to avoid clash with various scsh forks.
1321 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
1323 The following two changes (ramap.c, throw.c) are motivated by the
1324 apparent unportability of forward declarations of static arrays of
1325 the form `static foo bar[];'.
1327 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
1328 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
1330 * throw.c (scm_throw): Moved above scm_ithrow.
1332 * options.h: Removed the extern declarations of scm_yes_sym and
1333 scm_no_sym since these are static.
1335 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1337 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
1339 * Makefile.am: remove AWK=@AWK@.
1340 Add a rule for generating errnos.list.
1341 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
1343 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
1344 don't extract errnos, just set a variable (avoids the
1345 need to recompile error.c just because configure is run.)
1347 * unif.h: update prototypes.
1348 * unif.c (scm_uniform_array_read,write): change the offset and
1349 length arguments to start and end, for consistency.
1351 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
1353 * ioext.h: update prototypes.
1354 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
1355 scm_read_line_x, it's a more general procedure using an
1356 interface from scsh. read-line and read-line! are now defined
1358 Note that the new read-line trims the terminator
1359 by default, previously it was appended to the returned string. An
1360 optional argument specifies how to process the terminator (scsh
1361 compatible). For the old behaviour: (read-line port 'concat).
1362 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
1363 returns a pair, but is converted to multiple values if the scsh
1366 socket.h: update prototypes.
1367 * socket.c (scm_recvfrom): for consistency with other procedures,
1368 take start and end as separate optional arguments.
1369 (scm_recv, scm_recvfrom): don't allow the second argument
1370 to be a size, only a buffer. Change the scheme names to
1371 recv! and recvfrom!. Don't return the buffer.
1373 * ioext.h, posix.h: move prototypes too.
1374 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
1375 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
1376 "read.h" and "unif.h".
1377 * ioext.c: include "chars.h"
1379 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
1381 * dynl.c: The dynamic linking and module registration functions
1382 are now defined even when dynamic linking is not available for the
1383 host system. Some of their functionality can be done without
1384 dynamic linking; when it's really needed, they throw errors.
1386 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
1388 * configure.in: Only define DYNAMIC_LINKING when one of the system
1389 dependent functions is detected.
1390 * dynl.c (scm_dynamic_func): New function to get the address of a
1391 function in a dynamic object.
1392 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
1393 produced by scm_dynamic_func as the thing to call.
1395 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
1397 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
1398 (scm_register_module_xxx, scm_registered_modules,
1399 scm_clear_registered_modules): New functions.
1401 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
1403 * symbols.c (scm_sysintern): Renamed to
1404 scm_sysintern_no_module_lookup.
1405 (scm_sysintern): New function to take the place of the old
1406 scm_sysintern. It uses the current toplevel lookup closure to give
1407 the symbol its value. This is a temporary hack to put packages
1408 like gtcltk into their own module.
1409 (scm_can_use_top_level_lookup_closure_var): New variable to tell
1410 us whether `scm_top_level_lookup_closure_var' has been initialized
1412 * eval.c (scm_init_eval): Set it.
1414 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
1416 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
1417 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
1419 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
1421 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
1422 scm_sys_dup): deleted: FD capability will be added to other
1424 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
1425 scm_fd_free, fd_smob, scm_intern_fd.
1426 (scm_open): renamed from scm_sys_open. Return a port instead of
1427 an FD object. Make the mode argument optional.
1428 (scm_sys_create): deleted, it's just a special case of open.
1429 (scm_init_filesys): move interning of constants O_CREAT etc.,
1430 here (were previously using SCM_CONST_LONG macro).
1431 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
1433 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
1434 include "fports.h" and <stdio.h>
1435 (scm_stat, scm_select): don't support FD objects.
1437 * error.h: adjust scm_syserror_msg prototype.
1438 * error.c (scm_syserror_msg): take an extra argument for errno.
1439 Using the global value didn't always work, since it could be
1440 reset by procedure calls in the message or args arguments.
1442 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
1443 I don't understand why the check was there (and what about the
1446 * strop.c (scm_string_copy): allow shared substrings to be copied.
1448 * unif.h: corresponding change to prototypes.
1449 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
1450 recognize two new optional arguments: offset and length. Allow
1451 the port argument to be an integer (file descriptor, for scsh).
1452 Include <unistd.h> for "read" prototype.
1454 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
1456 * socket.c: don't include filesys.h.
1458 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
1460 * Makefile.am: add AWK=@AWK@ (?)
1462 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
1464 Add a rule to generate errnos.c from errnos.
1465 * error.c (scm_init_error): include errnos.c.
1466 * errnos_cnvt.awk: new file, converts the list of errno codes to
1468 * errnos_get.c: new file.
1469 * errnos.default: new file, contains errnos to try if they can't
1470 be extracted from errno.h.
1471 * configure.in: if using GCC, try and extract errno codes from
1475 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
1477 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
1478 * Makefile.am: Made libguile into a libtool library.
1479 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
1480 Set libtool_libs to indicate that libguile is a libtool library.
1481 See guile/ChangeLog for details.
1482 * .cvsignore: ignore "*.lo", the libtool library objects.
1484 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1486 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
1487 use htons in getservbyport argument.
1489 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
1491 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
1492 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
1495 * objprop.c (scm_object_property): No need to take the CDR of the
1496 value returned by scm_object_properties, since Aug 20 change.
1498 * configure.in: When checking for struct linger, #include
1499 <sys/types.h> as well as <sys/socket.h>. I've never known
1500 <sys/types.h> to cause any portability problems, and Solaris's
1501 <sys/socket.h> needs it.
1502 * configure: Rebuilt.
1504 I think the Sun compiler has chosen a perverse way to interpret
1505 ANSI declarations combined with K&R definitions. We'll
1506 appease it a little bit. But when it invades France, we fight.
1507 * print.c (scm_iprlist): Change 'tlr' argument to an int.
1508 * print.h (scm_iprlist): Here too.
1509 * numbers.c (scm_divbigdig): Change definition to match
1510 declaration in numbers.h.
1511 * unif.c (scm_makflo): Change definition to match declaration in
1514 * init.c (scm_boot_guile): Don't return the value of
1515 scm_boot_guile_1. This function doesn't return a value;
1516 scm_boot_guile_1 doesn't return a value (or return at all).
1518 * eval.c (unmemocopy): Add a semicolon to appease the Sun
1521 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
1522 compile. I have a feeling this function is a bad idea anyway ---
1523 one should always test for features, not systems.
1525 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
1526 semicolons. Only pure luck kept this from being noticed earlier.
1528 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
1530 * socket.c (scm_recvfrom): Added missing semicolon.
1532 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1534 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
1535 the buffer and start and end positions for scsh networking
1538 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
1540 * configure.in: Revert previous change to this file; the problem
1541 is due to transient automake weirdness.
1542 * configure: Rebuilt.
1544 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
1545 PLUGIN/guile.libs. configure generates the latter from the former.
1546 * Makefile.in: Rebuilt.
1548 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
1549 need this if we install scripts, like guile-snarf.
1550 * configure: Rebuilt.
1552 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1554 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
1556 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
1558 * socket.c (scm_addr_vector): fix faulty scm_listify.
1560 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
1562 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
1563 style block comment is no longer considered an error.
1565 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
1567 * PLUGIN/guile.libs.in: New file.
1568 * PLUGIN/guile.libs: Removed from repository.
1569 * configure.in: Create PLUGIN/guile.libs from
1570 PLUGIN/guile.libs.in. This is for including additonal libraries
1571 needed for dynamic linking.
1572 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
1573 instead of PLUGIN/guile.libs.
1575 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
1577 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
1579 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
1580 occurrences of the given element from the list, not just the
1581 first. This is how the Emacs Lisp functions behave, how the
1582 analogous Common Lisp functions behave, and (I believe) how the
1583 older Maclisp functions worked. I realize that this change may
1584 break code, but it seemed better to break it before the Guile
1587 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
1588 Their prototypes were already present in gc.h, but they weren't
1590 (scm_init_storage): Initialize scm_protects.
1591 * root.c (scm_protects): New element of scm_sys_protects.
1593 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
1595 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1597 * libguile.h: Added #include "libguile/net_db.h".
1599 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
1600 30 change. That file is only meant for communication between the
1601 configuration process and load.c. If code linked against libguile
1602 wants to get at the paths mentioned in libpath.h, it can call
1603 functions declared in load.h.
1605 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1607 * libguile.h: Removed #include "libguile/fdsocket.h"
1609 * net_db.c: Added #include <sys/socket.h>.
1611 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
1613 * filesys.c (scm_input_waiting_p): use select in preference to
1614 FIONREAD, since the latter doesn't detect EOF.
1615 Throw error if neither select nor FIONREAD available.
1617 * socket.c (scm_connect): take a port, not a fd object.
1618 (scm_fill_sockaddr): throw an error if fam is not recognised.
1619 (scm_bind): use scm_fill_sockaddr.
1620 (scm_listen): take a port, not a fd object.
1621 (scm_accept): take and return a port. return #f in the car if
1622 address can't be got
1623 (scm_sock_fd_to_port): new procedure.
1624 (scm_socket): use scm_sock_fd_to_port.
1625 (scm_addr_vector): throw error if unrecognised address type.
1626 take an extra argument with the calling procedure name.
1627 (scm_getsockname): take a port. return #f if address can't be got.
1628 (scm_getpeername): take a port. return #f if address can't be got.
1629 (scm_recvfrom): take a port. return #f for address component if can't
1631 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
1632 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
1634 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
1636 * throw.c (scm_internal_catch): Make body funcs and handler funcs
1637 use separate data pointers, to allow them to be designed
1638 independently and reused.
1639 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
1640 Renamed from catch_body, catch_handler, and uncaught_throw; made
1642 (struct scm_catch_body_data): Renamed from catch_body_data; moved
1644 (scm_catch): Use the above.
1645 (scm_throw): Don't bother printing a message for an uncaught
1646 throw; we establish a default handler in init.
1647 * throw.h (scm_internal_catch): Prototype updated.
1648 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
1650 (struct scm_body_thunk_data): New structure, used as data
1651 argument to scm_body_thunk.
1652 * init.c (struct main_func_closure): New structure, packaging up
1653 the data to pass to the user's main function.
1654 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
1655 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
1656 scm_internal_catch to establish a catch-all handler, using
1657 scm_handle_by_message. This replaces the special-case code in
1659 (invoke_main_func): Body function for scm_internal_catch; invoke
1660 the user's main function, using the main_func_closure pointer to
1661 decide what to pass it.
1662 * root.c (struct cwdr_body_data): Remove handler_proc member.
1663 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
1664 (cwdr_handler): Removed.
1666 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1668 * socket.h (SCM_P): update bind prototype.
1669 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
1670 include "feature.h".
1671 (scm_socket): return a port, not a file descriptor object.
1672 include "fports.h" and <unistd.h>
1673 (scm_bind): take a port, not a file descriptor object.
1674 take an extra argument for address args.
1676 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
1677 INADDR_NONE, INADDR_LOOPBACK.
1679 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1681 * init.c: include net_db.h and not fdsocket.h.
1682 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
1684 * Makefile.am: corresponding changes.
1685 * socket.h: renamed from fdsocket.h, fix names.
1686 * net_db.h: renamed from socket.h, fix names.
1687 * socket.c: renamed from fdsocket.c.
1688 remove _sys from procedure names.
1689 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
1690 add "socket" to features list.
1691 * net_db.c: renamed from socket.c.
1692 remove _sys from procedure names.
1693 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
1694 add "net-db" to features list.
1695 include "net_db.h". don't include <sys/socket.h> or
1698 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1700 * tags.h (scm_tags): Removed comma at end of last enumerator.
1702 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
1704 Don't use GCC extensions to allocate space for debugging frames.
1705 (Here he goes again! Why do we put up with this?!)
1706 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
1707 an scm_debug_info structure, not an in-line array of them. Add
1708 'info' member, to say how many vect elements we've used, for eval
1710 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
1711 a new variable debug_info_end to mark the end of vect, instead of
1712 the address of the 'info' pointer itself.
1713 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
1714 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
1715 (SCM_APPLY): Explicitly allocate space for debug.vect.
1716 * debug.c (scm_m_start_stack): Same, for vframe.vect.
1717 * stacks.c: Adjusted for new debug frame structure.
1718 (RELOC_INFO, RELOC_FRAME): New macros.
1719 (stack_depth, read_frames): Use them, and new scm_debug_frame
1720 element 'info', instead of magically knowing that eval frames have
1721 an info pointer sitting after vect.
1722 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
1724 (scm_init_stacks): Formatting tweaks.
1726 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
1728 Give GCC more control flow information, so it can be sure that
1729 variables aren't used uninitialized.
1730 * error.h (scm_error, scm_syserror, scm_syserror_msg,
1731 scm_sysmissing, scm_num_overflow, scm_out_of_range,
1732 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
1733 scm_misc_error): Tell GCC that these functions never return.
1734 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
1735 out the field type, call abort if SCM_ASSERT returns, to placate
1737 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
1738 scm_wta ever returns. We can't handle this case anyway, and this
1739 gives the optimizer more information.
1740 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
1741 scm_wta ever returns.
1743 In some cases, the code is fine, but GCC isn't smart enough to
1744 figure that out; this usually happens when one variable is only
1745 initialized and used when a particular condition holds true, and
1746 we know that condition will never change within a given invocation
1747 of the function. In this case, we simply initialize the variables
1748 to placate the compiler, hopefully to a value which will cause a
1749 crash if it is ever actually used.
1750 * print.c (scm_iprin1): Initialize mw_pos.
1751 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
1752 * throw.c (scm_ithrow): Initialize dynpair.
1753 * unif.c (scm_uniform_vector_ref): Initialize cra.
1754 * struct.c (init_struct): Initialize prot.
1755 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
1757 * strports.c (scm_eval_0str): Don't return uninitialized garbage
1758 if EXPR contains no expressions.
1760 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
1762 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
1763 cause an infinite loop (???). So much for the algebraic
1764 equivalency of variable-sized arrays and alloca...
1766 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
1768 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
1769 a SCM boolean, not a C boolean.
1771 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
1773 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
1774 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
1775 rules for raising scm_mtrigger. Previously, unfortunate but not
1776 unlikely circumstances could result in almost constant invokation
1777 of the gc. Now, this situations should be less likely, but they
1778 are not prevented completely.
1780 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
1782 * numbers.c (scm_fuck): Procedure removed; looks like old test
1784 * numbers.h: Prototype removed.
1786 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
1788 * debug.h (scm_debug_frame): Change `vect' member from an in-line
1789 array to a pointer, to match my Nov 21 change in eval.c.
1791 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1793 * libguile.h: Added #include "libguile/backtrace.h", #include
1794 "libguile/stacks.h".
1796 * strings.c (scm_string scm_make_string scm_string_ref
1797 scm_string_set_x scm_string_equal_p scm_string_append):
1798 Bugfix according to scm patch from Aubrey Jaffer:
1799 Corrected long-standing
1800 (not (eqv? (integer->char 128)
1801 (string-ref (make-string 1 (integer->char 128)) 0)))
1802 bug found by John Kozak <jk@noontide.demon.co.uk>.
1804 * strports.c, strports.h: Make scm_eval_0str return the value of
1805 the last expression evaluated (previously, it returned void).
1807 * strports.c, strports.h: New function: scm_read_0str. Does what
1810 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1812 * simpos.c (scm_getenv): return #f if string can't be found in the
1813 environment instead of throwing an exception, for compatibility
1814 with numerous other systems.
1816 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
1818 * Makefile.am (.c.x): Use guile-snarf.
1819 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1821 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1823 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1825 * backtrace.c (scm_display_error_message): Made non-static, and
1826 renamed from display_error_message.
1827 * backtrace.h (scm_display_error_message): Added extern decl.
1828 * throw.c (uncaught_throw): Use it to display the error message.
1830 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1832 * inet_aton.c: Use #if 0, not #ifdef 0.
1834 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1836 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1837 to convert the returned value.
1838 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1839 the offset argument.
1841 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1843 Add new interface to catch/throw, usable from C as well as
1845 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1846 (scm_internal_catch): New function, replaces...
1847 (scm_catch_apply): Deleted.
1848 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1849 mechanism which is a bit more code, but can be used nicely from C
1850 and implement the Scheme semantics as well.
1851 (scm_internal_catch): This is the replacement; it's named after
1852 the analogous function in Emacs.
1853 (scm_catch): Reimplemented in terms of the above.
1854 (struct catch_body_data, catch_body, catch_handler): New
1855 functions, used by scm_catch.
1856 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1857 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1858 support for new cwdr.
1860 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1863 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1865 * acconfig.h: Added DYNAMIC_LINKING symbol.
1866 * configure.in: Add option and checks for dynamic linking.
1867 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1868 dynl.h: New files for dynamic linking support.
1869 * Makefile.am (libguile_a_SOURCES):
1871 (modinclude_HEADERS): Added "dynl.h".
1872 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
1874 * init.c (scm_boot_guile_1): Call
1875 scm_init_dynamic_linking to initialize dynamic linking support.
1877 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
1879 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
1880 (as we Schemers say). It needs to be global, so that I can tweak
1881 it for the proper operation of unexec.
1882 (scm_boot_guile_1_live): New variable, see above.
1884 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
1886 * guile-snarf.sh: Removed.
1887 * PLUGIN/guile.libs: Added dependency for -lm.
1888 * acinclude.m4: Renamed from aclocal.m4.
1889 * PLUGIN/greet: Removed.
1890 * Makefile.am, aclocal.m4: New files.
1891 * configure.in: Updated for Automake.
1893 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
1895 * eval.c (scm_definedp): Use top_level_lookup_closure_var
1896 and not top_level_lookup_thunk_var.
1898 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
1900 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
1902 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
1904 * eval.c (scm_definedp): Incompatibly changed to be a builtin
1905 Scheme function, instead of syntax. Single argument is now a
1908 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
1910 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
1911 scm_ra_divide): Properly terminate statements passed as arguments
1912 to IVDEP macros. (Thanks to Bernard Urban.)
1914 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
1915 with non-constant sizes. (Thanks to Bernard Urban.)
1917 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
1919 It's an "eval closure", not an "eval thunk." A thunk is a
1920 function of no arguments.
1921 * root.h (struct scm_root_state): Renamed
1922 top_level_lookup_closure_var from top_level_lookup_thunk_var.
1923 (scm_top_level_lookup_closure_var): Renamed from
1924 scm_top_level_lookup_thunk_var.
1925 * root.c (mark_root): Uses changed.
1926 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
1927 * init.c (scm_start_stack): Uses changed.
1928 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
1929 Change scheme-visible name to *top-level-lookup-closure* from
1930 *top-level-lookup-thunk*.
1932 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
1934 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
1935 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
1937 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
1939 * gc.c (struct scm_heap_seg_data): Doc fixes.
1941 * gc.c (scm_gc_sweep): Empty all segments' freelists before
1942 sweeping. Then, prepend each segment's free cells to its
1943 freelist, rather than wiping out the old value. (Thanks to Marius
1946 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
1947 scm_check_freelist, scm_debug_newcell): New functions and
1948 variables, for debugging freelist problems.
1949 * pairs.h (SCM_NEWCELL): New debugging version added.
1950 * gc.h (scm_debug_newcell): Added extern declaration, used by
1951 debugging version of SCM_NEWCELL.
1953 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
1955 On some systems <libc.h> conflicts with <unistd.h>, and should not
1956 be #included at all.
1957 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
1958 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
1959 * configure.in: Call it.
1960 * posix.c, filesys.c: Use its results to decide whether or not to
1962 * configure, scmconfig.h.in: Rebuilt with autoconf and
1965 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
1967 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
1968 pointer to the stdio stream before calling scm_setbuf0, so the
1969 latter will be able to retrieve it. I'm surprised this didn't
1970 segfault earlier. (Thanks to Christopher Lee.)
1972 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1974 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
1977 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1979 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
1980 number of stack narrowing specifier pairs. The first specifier in
1981 a pair controls inner border, the second the outer border. A
1982 number means cut that number of frames, a procedure object means
1983 cut until that object is found in operator position in a frame.
1985 * root.c (cwdr): Bugfix.
1987 * read.c: Recording of positions disabled by default.
1989 * procs.c (scm_closure_p): New function.
1991 * posix.c (scm_tmpnam): New function.
1993 * load.c: Added #include "throw.h".
1994 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
1997 * load.c, load.h (scm_read_and_eval_x): New function.
1999 * eval.c: Renamed debug option "deval" to "debug".
2001 (scm_eval_x): `eval!' is no longer accessible from the scheme
2002 level. Motivation: We can't allow operations which introduce
2003 glocs into the scheme level. Guile's type system can't handle
2004 these as data. Use `eval' or `read-and-eval!' as replacement.
2006 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
2007 SCM_CONSP since this is a macro!; Set vframe.prev to
2008 scm_last_debug_frame instead of 0. In this way we can look
2009 "above" the virtual start stack frame if we wish.
2010 (scm_debug_hang): New function: Useful for debugging Guile in
2011 certain tricky situations. Will probably be removed later...
2013 * debug.h: Changed semantics of debug option "backtrace". This
2014 option now only indicates whether we want automatic backtrace at
2017 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2019 * ports.c: #include "filesys.h"
2020 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
2022 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
2023 Motivation: This is system specific code which is related to file
2024 I/O. It also may use select. Added code by Gary Houston to
2025 detect presence of character in stdio buffers.
2027 * libguile.h: #include "libguile/libpath.h"
2029 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
2030 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
2031 SCM_SITE_DIR; Install libpath.h among the other include files.
2033 * load.c, load.h (scm_sys_package_data_dir): New function.
2035 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2037 * stacks.h: Bugfix: Don't use tail-array length field as stack
2038 length field! This screwed GC.
2040 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2042 * _scm.h: Added #ifndef around definition of macros min and max.
2044 * __scm.h: Added hooks for threads to plugin to in ints protection
2045 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
2046 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
2047 the main code in these macros duplicated and spread over multiple
2048 files. Renamed SCM_THREADS_SWITCHING_CODE ->
2049 SCM_THREAD_SWITCHING_CODE.
2051 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
2053 * snarf.h: New file.
2054 * guile-snarf.sh: New file.
2055 * Makefile.in (inner_h_files): Added snarf.h
2056 (ancillary, install, uninstall, distclean): Added actions for
2058 (.c.x): Use guile-snarf.
2059 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
2060 (gen_c_files): Note that these depend on guile-snarf.
2061 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
2062 now in "snarf.h". Added #include "snarf.h" to get them.
2063 * libguile.h: Added #include "snarf.h".
2064 (Patches applied and tweaked by Jim Blandy.)
2066 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2068 * socket.c: Use K&R style declaration for 'close'; the GNU coding
2069 standards suggest against providing prototypes for system
2070 functions. Thanks to Greg Troxel.
2072 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
2074 * strports.c (scm_eval_0str): New function.
2075 #include "read.h", to get prototype for scm_read.
2076 * Makefile.in (strports.o): Update dependencies.
2077 * strports.h: New prototype.
2079 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
2080 scheme name from "int?" to "integer?". It seems to do the job.
2081 * numbers.h: Rename prototype too.
2082 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
2085 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
2086 scm_num_eq_p): Rename these according to R4RS conventions: call
2087 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
2088 to making libguile R4RS compliant without ice-9...
2090 * load.c (scm_sys_search_load_path): Search for files under all
2091 extensions listed in the %load-extensions variable. If FILENAME
2092 is absolute, return it unchanged, without searching the load path.
2093 (scm_loc_load_extensions): New variable, pointing to
2094 %load-extensions' value cell.
2095 (scm_init_load): Initialize it, and the value it points to.
2096 (scm_primitive_load_path): Improve error reporting.
2098 * load.c (scm_loc_load_hook): New variable, pointing to value cell
2099 of new Scheme variable %load-hook.
2100 (scm_primitive_load): Apply %load-hook to filename.
2102 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
2104 * configure.in: add tests for figuring out whether buffered data
2105 is available in a FILE structure, which is needed by char-ready.
2107 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
2110 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
2111 exceptions using misc_error instead of syserror. It seems a bit
2112 odd to throw an exception if a string can't be found in the
2113 environment, but it's consistent with open-file, stat etc.
2114 (simpos.h): remove sys_ from getenv.
2116 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
2117 occurs, throw an error instead of returning errno. Return value
2119 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
2121 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
2123 * filesys.c (scm_stat2scm): derive file type and permissions from
2124 the stat mode and append them to the returned vector.
2125 There isn't much overhead in doing this and it avoids the need to
2126 work with S_IRUSR et al. in Scheme.
2127 Define symbols scm_sym_regular etc.
2128 (scm_init_filesys): don't intern S_IRUSR etc.
2130 * load.c: change s_try_load and s_try_load_path to s_primitive_load
2131 and s_primitive_load_path.
2133 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
2135 * error.h: don't declare error symbols. prototype for scm_misc_error.
2137 * stackchk.c (scm_stack_overflow_key): defined here instead of in
2140 * error.c: use SCM_SYMBOL to set up error keys.
2141 scm_misc_error: new procedure.
2143 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2145 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
2146 between `#!' and `!#' is ignored.
2147 (skip_scsh_block_comment): New function.
2149 * feature.c (scm_set_program_arguments): New argument, FIRST.
2150 * feature.h: Update prototype.
2151 * init.c (scm_boot_guile_1): Pass new argument to
2152 scm_set_program_arguments.
2154 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
2156 * init.c (scm_start_stack): Don't initialize scm_progargs here.
2157 (scm_boot_guile): Call scm_set_program_arguments here, later than
2158 the old initialization.
2160 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
2161 initialization procedure.
2162 - Delete in, out, err arguments; there are other perfectly good
2163 ways to override these when desired.
2164 - Delete result argument; this function shouldn't ever return.
2165 - Rename init_func argument to main_func, for less confusion.
2166 - Delete boot_cmd argument; main_func is more general.
2167 -Add 'closure' argument, to help people pass data to main_func
2168 without resorting to global variables.
2169 - Abort if reentered; don't bother returning an error code.
2170 - Call scm_init_standard_ports to set up the default/current
2171 standard ports; no need to pass them to scm_start_stack.
2172 - Remove code to evaluate the boot_cmd, and start the repl; let
2173 the user do something like that in main_func if they want.
2174 - Remove code to package up a return value; main_func can do any
2176 - Call exit (0), instead of returning.
2177 (scm_start_stack): Don't initialize the I/O ports here; that's
2178 weird. Delete in, out, err arguments. Move guts to
2179 scm_init_standard_ports, scm_stdio_to_port.
2180 (scm_init_standard_ports): New function, to set up current and
2181 default standard ports.
2182 (scm_start_stack, scm_restart_stack): Make these static.
2183 * init.h (scm_boot_guile): Adjust declaration.
2184 (scm_start_stack, scm_restart_stack): Remove externally
2185 visible declarations for these.
2186 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
2188 * fports.c (scm_stdio_to_port): New function. Its guts used to be
2189 written out several times in scm_start_stack.
2190 * fports.h: New declaration for the above.
2192 * feature.c (scm_set_program_arguments): New function.
2193 * feature.h: New declaration for the above.
2195 * ports.c: Formatting tweak.
2197 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
2199 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
2200 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
2201 for obtaining the address of a car or cdr field. Motivation:
2202 &SCM_CXR make assumptions about the internal structure of the
2205 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
2206 Motivation: see SCM_CXRLOC.
2208 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
2209 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
2210 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
2211 Motivation: Safer use. Some other macros are defined in terms of
2212 these operations. If these are defined using the SCM_SETCXR
2213 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
2214 to inefficiency and an <e1> with side-effects could potentially
2215 break. Also, these particular operations are heavily utilized in
2216 the garbage collector. In unoptimized code there will be a
2219 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
2220 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
2221 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
2222 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
2223 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
2224 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
2225 vports.c: Cleaned up use of pairs: Don't make any special
2226 assumptions about the internal structure of selectors and
2227 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
2228 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
2229 (Among other things, this change makes it easier to build Guile
2230 with certain compilers which have problems with casted lvalues.)
2232 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2234 * stacks.c: Improve selection of relevant stack frames when making
2235 a stack object. Introduce one level of indirection in the stack
2236 object to make it possible to "narrow" to a certain region of the
2237 stack. This facilitates making use of more clever algorithms (not
2238 implemented) for selecting relevant frames and gives a cleaner
2239 design since selection of frames can be done independently of
2240 extraction of frames from the real stack.
2241 (scm_stack_id): Also take #t as argument which means look at
2244 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
2245 Turn n_tail into an integer directly representing current number
2246 of frames in stack. Add field tail.
2248 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
2250 * debug.c (scm_make_memoized): Made it available at scheme level.
2251 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
2252 SCM_NIMP before applying heavier predicates in argument checking.
2253 (scm_local_eval): Also take memoized object as argument.
2255 * backtrace.c (scm_display_error): Just a safety measure: Stacks
2256 aren't created with zero length, but should such a strange
2257 creature suddenly turn up...
2259 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
2261 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
2262 `del', for the sake of C++ compilers. (Patch applied by JimB.)
2264 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
2266 * variable.c (scm_make_variable): Make the name hint optional, as
2268 (anonymous_variable_sym): Renamed from variable_sym. All uses
2271 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
2272 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
2273 of scm_primitive_load_path was also changed to
2274 "primitive-load-path", from "%try-load-path". Callers changed.
2275 We'd like to respect the convention that a function named
2276 "try-mumble" should behave just like the function called "mumble",
2277 but return #f instead of signalling some error.
2278 * load.h: Rename prototypes.
2280 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2282 * print.c (make_print_state, grow_print_state), print.h: Modified
2283 the print state representation: Don't use a tail array for
2284 recording of circular references. Resizing of the print state
2285 structure invalidates the print state pointer. To avoid passing
2286 around an indirect print state reference to all printing
2287 functions, we instead let the print state reference a resizable
2290 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2292 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
2293 Don't crash when passed an improper list terminated by a
2294 non-immediate value.
2296 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
2298 Allocate data for structures on an eight-byte boundary, as
2299 required by the tagging system.
2300 * struct.c (alloc_struct): New function.
2301 (scm_make_struct, scm_make_vtable_vtable): Call it.
2302 * struct.h (scm_struct_n_extra_words): Bump to 3.
2303 (scm_struct_i_ptr): New "field".
2304 * gc.c (scm_gc_sweep): When we need to free the data, use the
2305 information stored by alloc_struct to find the beginning of the
2306 block allocated to the structure, so we can free it.
2308 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2310 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
2313 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
2314 (scm_debug_info): New member: id.
2316 * stacks.c: Stacks are now represented as structs; Stacks have an
2317 id given to them by `start-stack'.
2318 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
2320 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
2321 Changed stack representation.
2323 * debug.c (scm_procedure_name): Try procedure property `name' for
2324 compiled closures aswell.
2326 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
2328 * eval.c: scm_i_name moved to gsubr.c
2329 (scm_m_define): Record names of all kinds of procedure
2330 objects. (Earlier, only closures were recorded.)
2332 * procprop.h: Added declaration of scm_i_name.
2334 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
2335 (scm_make_gsubr): Record names of compiled closures.
2337 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2339 * debug.c, debug.h: Removed obsolete code.
2341 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
2342 stacks.c: Renamed regs --> scm_contregs.
2344 * print.c (scm_free_print_state): Cleanup print state before
2345 returning it to pool. It is better to do it here than in
2346 scm_prin1 since scm_prin1 is called often.
2348 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
2349 s_set_source_property_x): Check that first argument is a pair or a
2352 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
2353 scm_i_line, scm_i_column and scm_i_breakpoint global.
2355 * init.c: Added #include "backtrace.h" and #include "stacks.h".
2356 (scm_boot_guile_1): Added calls to scm_init_backtrace and
2359 * debug.h: Added debug object smob declaration and macro
2362 * configure.in: Build with backtrace.o and stacks.o if debug
2365 * Makefile.in: Added entries for new files: backtrace.c,
2366 backtrace.h, stacks.c and stacks.h.
2368 * symbols.c (scm_sym2ovcell): Fixed documentation.
2370 * _scm.h (min, max): Added.
2372 * async.c: Moved `min' macro to _scm.h.
2374 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
2375 SCM_BACKTRACE_INDENT.
2377 * eval.c: Added new debug options `maxdepth' and `indent'.
2379 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
2381 * print.h: Added selector SCM_PRINT_STATE.
2383 * print.c: New functions: scm_make_print_state,
2384 scm_free_print_state.
2386 * print.h: Added declarations for scm_make_print_state,
2387 scm_free_print_state.
2389 * debug.c (scm_m_start_stack): New acro.
2391 * debug.h: Small cleanup.
2393 * init.c (scm_boot_guile_1): Moved scm_init_debug below
2396 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
2398 * __scm.h, alist.c, alist.h, append.c, append.h, appinit.c,
2399 arbiters.c, arbiters.h, async.c, async.h, boolean.c, boolean.h,
2400 chars.c, chars.h, continuations.c, continuations.h, debug.c,

2421 More prototype-related changes from Marius Vollmer:
2422 * gdb_interface.h: Wrapped header file in #ifdef/#endif
2423 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
2424 * ports.h (ptobfuns): Added prototypes. This means some casting in
2426 * fports.c: Added casts for initializations, since the functions
2427 are defined to take FILE * as their stream argument, not SCM.
2428 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
2429 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
2430 to `char *str_data' to conform to prototype.
2432 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2434 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
2436 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
2438 * stime.c, stime.h: use SCM_P method.
2440 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2442 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
2443 be given at least two arguments. Insist that lst's last element
2444 be a list, but don't make any requirements of its predecessors.
2446 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2448 * eval.c (scm_nconc2last): Revert last change; there seems to be
2449 other stuff going on here.
2451 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2453 * eval.c (scm_nconc2last): Make sure that each element of lst
2454 (which is a list of argument lists, except for the tail) is a
2455 proper list, i.e., finite and terminated by '().
2457 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2459 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
2462 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
2463 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
2466 * vectors.c (scm_make_vector): Fill vectors with the undefined
2467 value, to help make Guile Scheme code more portable to other
2470 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
2471 * symbols.h, tags.h: Doc fixes.
2473 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
2475 * async.c (scm_take_signal): Doc fixes.
2477 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
2479 * numbers.c (scm_divbigint): When the remainder is zero, we don't
2480 want to subtract it from the modulus; we just want to leave it
2483 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
2485 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
2488 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
2490 * throw.c (scm_catch_apply): Finished implementation of
2493 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2495 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
2497 (scm_init_filesys): set "i/o-extensions" feature.
2500 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
2502 * Makefile.in (root.o): Correct dependencies.
2504 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
2506 * Makefile.in: Added dependency entry for root.o.
2508 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
2509 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
2511 * init.c (scm_start_stack): Set initial root continuation number
2514 * procs.c: New function: scm_thunk_p.
2516 * procs.h: Added declarations of scm_thunk_p.
2518 * root.c: Renamed `call-with-new-root' -->
2519 `call-with-dynamic-root'.
2520 (cwdr): Removed allocation of new root state. This should be done
2521 separately by use of scm_make_root.
2522 (scm_apply_with_dynamic_root): New function: Does what it
2523 sounds like. Needed when spawning threads.
2525 * root.h: Added member last_debug_frame to root state.
2526 Added #include "libguile/debug.h"
2528 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
2529 arguments. The motivation is that code in root.c needs catch
2530 functionality, and we want to avoid code duplication.
2531 New functions: scm_catch, scm_lazy_catch. These are wrappers for
2532 scm_catch_apply. scm_lazy_catch is intended to introduce catch
2533 handlers that run without popping the stack into the dynwind
2536 * throw.h: Added prototypes for scm_catch_apply and
2539 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2541 * root.h (scm_root, scm_set_root): Decouple thread support details
2542 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
2543 SCM_SET_THREAD_LOCAL_DATA.
2545 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
2546 and tortoise scanning loop.
2548 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
2550 * Makefile.in: Rebuild dependencies.
2552 * libguile.h: #include "libguile/print.h" before "smob.h", since
2553 the latter uses the print_state structure.
2555 * throw.c (scm_ithrow): Use the correct variable when checking to
2556 see if a given element of scm_dynwinds is a valid catch.
2558 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
2559 structure, abort; don't just silently ignore the garbage.
2561 * _scm.h: #include "print.h" here, since it seems to be used just
2563 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
2564 strports.c, unif.h: Don't #include "print.h".
2566 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2568 * feature.h (scm_loc_features): Removed external declaration.
2569 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
2571 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2573 * feature.c (scm_init_feature): Added threads feature (needs to be
2574 initialized here, since features doesn't exist when
2575 scm_init_threads is called).
2577 * libguile.h: Added #include "libguile/../threads/threads.h".
2578 (This is a kludge to get thread support working. This should be
2581 * configure.in, acconfig.h: Added flags for thread support.
2583 * scmsigs.c: Define `signal' to be `pthread_signal' if using
2586 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
2587 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
2590 * _scm.h: Added conditional #include "threads.h"
2592 * __scm.h (SCM_ASYNC_TICK): Added call to macro
2593 SCM_THREADS_SWITCHING_CODE.
2595 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
2596 allocate the basic dynamic root object.
2597 (scm_boot_guile): Added call to scm_init_root.
2599 * root.c, root.h: Added root smob.
2600 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
2601 functions: Implements dynamic roots mostly according to spec in
2602 SCM manual. Main difference is that the second argument is a
2603 throw handler rather than an error "thunk".
2605 * root.h: Added declaration of scm_init_root.
2607 * root.c: Added #include "genio.h", #include "smob.h", #include
2608 "pairs.h", #include "throw.h", #include "dynwind.h", #include
2610 (scm_init_root): Added #include "root.x".
2612 * throw.c: Added #include "stackchk.h"
2613 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
2614 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
2615 can be used in scm_call_with_new_root; Added reenabling of stack
2616 checking when catching a throw.
2618 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
2620 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
2622 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
2623 element is not found, as per R4RS.
2625 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2627 * list.c: Doc fixes throughout.
2629 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2631 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
2632 declare the char * to be const. Avoids a warning in rgx.c.
2634 * ports.h: spelling fix.
2636 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
2639 * load.c (scm_sys_try_load_path): throw an error if file not found
2640 (like it says it in NEWS).
2642 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2644 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
2645 PROPS slot to '(), not #f; it's an empty alist.
2647 * throw.h, throw.c: Use SCM_P instead of #if hair.
2649 Remove special support for uncaught throws; see throw.c for
2651 * throw.c (uncaught_throw): New function.
2652 (scm_ithrow): Call uncaught_throw if we don't find a throw
2653 target; don't mess with scm_bad_throw_vcell.
2654 (scm_bad_throw_vcell): Variable deleted.
2655 (scm_init_throw): Don't initialize it.
2657 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
2660 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2662 * numbers.c (scm_istr2int): If the number is short (as most
2663 numbers are), just call scm_small_istr2int to deal with it.
2664 (scm_small_istr2int): New function, created by un-#ifdefing the
2665 non-bignum version of scm_istr2int and renaming it.
2667 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
2669 * load.c (scm_sys_try_load): don't check whether value returned
2670 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
2671 Change the Scheme name from %try-load to primitive-load.
2673 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
2674 Can avoid passing a message, allowing it to be derived in the
2675 error handler (e.g., if we want to throw to the key both from
2678 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
2680 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
2681 references now have a new appearance which is more compact and
2682 also gives a clue about what the target of the reference is.
2683 By setting parameters in the print state, more fancy printing can
2684 be achieved. This is used by the (not yet commited) backtrace
2687 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
2689 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
2692 * print.c: Added #include "struct.h". Removed function
2695 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
2696 scm_iprin1. Removed prototype for scm_prlist.
2698 * arbiters.c (prinarb),
2699 async.c (print_async),
2700 debug.c (prindebugobj, prinmemoized),
2701 eval.c (prinprom, prinmacro),
2702 filesys.c (scm_fd_print, scm_dir_print),
2704 mallocs.c (prinmalloc),
2705 numbers.c, numbers.h (scm_floprint, scm_bigprint),
2706 smob.h (scm_smobfuns),
2707 srcprop.c (prinsrcprops),
2709 unif.c, unif.h (scm_raprin1, rapr1),
2710 variable.c (prin_var): Changed argument `int writing' to
2711 `scm_print_state *pstate'.
2713 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
2714 that it will be called before scm_init_print.
2716 * print.c (scm_prin1): Print states are now allocated when calling
2717 scm_prin1 and then passed around to all printing functions as an
2718 argument. A cache `print_state_pool' enables reuse of print
2720 (scm_make_print_state): New function.
2721 (scm_iprin1): Adaption to print states.
2722 (scm_iprlist): An initial "hare and tortoise" scan brings down
2723 time complexity to O (depth * N). (Better time complexity will be
2724 achieved when the printing code is completely rewritten.)
2726 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2728 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
2729 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
2730 it gets done whether or not the cache variable has a value.
2732 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2734 Distinguish #f and ().
2735 * __scm.h: #undef SICP.
2736 * pairs.h (SCM_EOL): Delete this definition, equating it with
2738 * tags.h (SCM_EOL): Give it a new definition here; I think I found
2739 the value it used to have. Doc fixes, too.
2741 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
2743 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
2744 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
2745 Lord's implementation of structs, allowing for tail arrays as
2746 described in the manual. Also fixed some bugs. (Both the interface
2747 and the implementation should be improved.)
2749 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
2751 * print.c, print.h: Closures now print like #<procedure foo (x)>.
2752 People who whish to see the source can do `(print-enable 'source)'.
2753 Removed #ifdef DEBUG_EXTENSIONS.
2755 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2757 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
2758 integer (assuming for now accepting an integer is a good thing).
2760 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2761 %S will be used instead for write'ing arguments.
2763 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2764 asserts. fix a few other asserts.
2765 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2766 scm_uniform_vector_ref, scm_array_set_x,
2767 scm_dimensions_to_unform_array): change args in
2768 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2769 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2770 scm_substring_fill_x): likewise.
2771 gsubr.c (scm_gsubr_apply): likewise.
2772 eval.c (SCM_APPLY): likewise.
2774 * eval.c (4 places): replace scm_everr with lgh_error or
2777 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2778 scm_memory_error): new procedures.
2779 scm_everr: deleted. can use scm_wta, dropping first two args.
2780 scm_error: convert NULL subr to SCM_BOOL_F.
2782 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2785 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2788 * error.c, error.h: new error keys: scm_arg_type_key,
2789 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2791 scm_wta: reimplement using lgh_error instead of scm_everr.
2793 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2795 * gdbint.c: scm_lread now has one more argument.
2797 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2798 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2799 loading source from non-file ports, which, e. g., happens when
2800 using the Emacs interface).
2802 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2805 * read.c: Added code for recording of positions of source code
2806 expressions; New functions: recsexpr, scm_lreadrecparen;
2807 _scm_make_srcprops --> scm_make_srcprops
2808 (scm_flush_ws): Removed updating of positions counters. This work
2809 is already done by scm_gen_getc
2811 * read.h: Added prototype for scm_lreadrecparen
2813 * print.c: Added #include "alist.h"
2815 * eval.c: Added #include "hash.h"
2817 * eq.c: Added #include "ramap.h"
2819 * options.c: Documentation fixes.
2821 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
2822 (scm_init_srcprop): Adjusted size of initial source-whash. Name
2823 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2824 --> scm_make_srcprops
2826 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2827 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2828 function calls in the definition of the whash access macros.
2830 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2832 * init.c (scm_boot_guile): Add level of indirection to
2833 scm_boot_guile_1() to ensure that stack base pointer is properly
2834 initialized. There was no guarantee that variable i was the
2835 highest/lowest variable on stack (i.e. the call frame of
2836 scm_boot_guile was not completely protected from gc).
2838 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2840 * ports.h (scm_port_table): put back file_name, it will be used to
2841 support debugging. Undo related changes in fports.c, ioext.c,
2844 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2846 * ports.h (scm_port_table): remove file_name member for now, it seems
2848 * fports.c (scm_open_file): don't set file_name in PTAB.
2849 (prinfport): don't use file_name in PTAB.
2850 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2851 * ports.c (scm_add_to_port_table): don't intialize file_name.
2852 (scm_port_file_name): remove for now.
2853 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2855 * fports.h (scm_mkfile): prototype deleted.
2856 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2858 * debug.c, unif.c: use scm_out_of_range instead of
2859 wta for range errors (ASSERT still needs work).
2861 * error.c, error.h (scm_out_of_range): new procedure.
2863 * error.c, error.h (scm_out_of_range_key): new key.
2865 * posix.c (scm_sync): #else was missing.
2867 * error.c, error.h: append _key to names scm_num_overflow and
2870 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
2871 of consing an empty list.
2872 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
2873 of macros, saves code and string space.
2874 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
2875 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
2876 lower case. Rename scm_syserror_m to scm_syserror_msg.
2877 error.h: prototypes for new procedures.
2879 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
2881 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
2883 * error.c, error.h: setup scm_num_overflow key.
2885 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
2886 Remove definition of SCM_OVSCM_FLOW.
2888 * fports.c (scm_open_file): use SCM_SYSERROR_M.
2890 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
2891 explicit message and args.
2893 * error.c, error.h, __scm.h: change system_error_sym to
2896 * error.c (system_error_sym): remove leading %% from the Scheme name
2899 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
2901 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2903 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
2904 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
2905 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
2906 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
2907 renamed. (These were introduced by unsupervised name
2910 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2912 * print.c: Added code for detection of circular references during
2913 printing. (init_ref_stack, grow_ref_stack): New functions. Added
2914 a hook for printing of closures (accessible via print options).
2915 This leads to a split of calls to scm_iprin1 into two classes:
2916 elementary print operations (e. g. the code which prints a smob)
2917 still use scm_iprin1 while top level calls (like scm_display) use
2918 scm_prin1. scm_prin1 begins by clearing the data structure used
2919 to record reference information.
2921 * print.h: Added declarations of scm_prin1 and scm_prlist.
2923 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
2925 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
2927 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
2929 * error.c (err_head): scm_iprin1 --> scm_prin1
2931 * debug.c: Adjusted header comment.
2935 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2937 * strerror.c: Doc fix.
2939 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2941 * gdbint.c (gdb_read): Now possible to run during GC.
2942 (unmark_port, remark_port): New functions.
2944 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
2946 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
2947 of allocating a new string object. Also, increase size by
2948 the factor 2 instead of 1.5.
2950 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
2952 * __scm.h (SCM_P): Corrected to run under traditional C.
2954 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
2957 * async.c: Calls to scm_sysintern corrected.
2959 * async.h (scm_async_clock): Redundant declaration removed.
2961 * continuations.c (scm_dynthrow): Redundant declaration removed.
2963 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
2964 Definition typos corrected.
2966 * debug.h: Missing declarations of functions in debug.c added
2969 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
2970 Missing declarations to functions in eval.c added.
2972 * filesys.c: Possibly uninitialized variable rv.
2974 * gc.h (scm_object_addr, scm_unhash_name): Missing
2975 declarations of functions defined in gc.c added.
2977 * genio.c: Possible typos str_data -> wstr_data. ???
2979 * genio.c: Possibly unintended shadowing of local variable
2980 `int c' (gotos out of scope of inner `c'). ???
2982 * init.c: Uninitialized `SCM last' may be used.
2984 * ioext.h: (scm_sys_isatty_p): Typo.
2986 * list.h (scm_list_head): Missing prototype for function in
2989 * numbers.c (scm_two_doubles): Changed from extern to static
2990 (is used only within numbers.c).
2992 * numbers.h: Repeated declarations removed.
2994 * ports.h (scm_close_all_ports_except): Declaration for the
2995 function defined in ports.c added.
2997 * posix.h: Missing declarations added.
2999 * procs.h (scm_make_subr_opt): Missing declaration added.
3001 * socket.h (scm_sys_gethost): Missing declaration added.
3003 * socket.h: Redundant declarations removed (they are in fdsocket.h).
3005 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
3006 Missing declarations added.
3008 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
3010 * struct.c: Uninitialized variable `SCM answer' may be used.
3012 * unif.c (l2ra): Declaration prototype.
3014 * unif.c (scm_array_equal_p): Dummy definition removed (it is
3015 defined in ramap.c).
3017 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
3018 Redundant declarations removed (they are in ramap.h).
3020 * variable.h (scm_make_udvariable,
3021 scm_make_undefined_variable): Declaration corrected to
3022 correspond variable.c.
3024 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
3025 Missing declarations added.
3027 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
3029 * Makefile.in (distclean): Don't forget to delete fd.h.
3031 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3033 * fd.h.in, tags.h: Trivial cleanups.
3035 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
3036 marksweep.h just declared functions from gc.c.
3037 * gc.h, libguile.h: Don't #include "marksweep.h".
3038 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
3039 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
3040 dependencies updated.
3042 * libguile.h: Don't #include "files.h"; it's been deleted.
3044 * files.c (scm_sys_delete_file): Moved to filesys.c.
3045 File is now empty; deleted.
3047 * filesys.c: scm_sys_delete_file is now here. Remove
3048 #if's; they seem to rely on remnants of an old portability
3049 regimen. If the problems come up again, solve them properly,
3050 using autoconf. Specifically: Don't test M_SYSV, and #define
3051 remove to be unlink if it's #defined; don't use remove just
3052 because HAVE_STDC_HEADERS is #defined.
3053 * filesys.h: Add declarations for scm_sys_delete_file.
3054 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
3055 files.o, files.h, files.c, and files.x.
3056 * init.c: Don't #include "files.h", and don't call scm_init_files.
3058 Use SCM_P instead of PROTO; the latter intrudes on the user's
3060 * params.h: Deleted; definition of SCM_P moved to...
3061 * __scm.h: ... here, where it replaces PROTO macro.
3062 * libguile.h, smob.h: Don't #include "params.h".
3063 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
3064 smob.h: Fix prototypes accordingly.
3065 * Makefile.in: Update dependencies.
3066 (inner_h_files): Remove params.h.
3068 * gc.c: #include "gc.h"; every module should include its header,
3069 to let the compiler cross-check the declarations against the
3072 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
3073 simpos.h: #include "libguile/__scm.h".
3075 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
3077 * init.c: Don't forget to #include smob.h and init.h.
3078 * Makefile.in: Dependencies updated.
3080 * smob.h: Use PROTO instead of #if __STDC__.
3082 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
3084 * __scm.h: Doc fixes.
3086 * __scm.h, libguile.h: Use "quotes" in the #includes, not
3087 <angles>; this allows `make depends' to work properly.
3089 * libguile.h: #include smob.h and pairs.h before the others; they
3090 define typedefs used by other headers.
3092 C files should #include only the header files they need, not
3093 libguile.h (which #includes all the header files); the pointless
3094 recompilation was wasting my time.
3095 * Makefile.in (all .o dependency lists): Regenerated.
3096 * libguile.h: Don't try to get a definition for size_t here...
3097 * __scm.h: Do it here.
3098 * _scm.h: Since this is the internal libguile header, put things
3099 here that all (or a majority) of the libguile files will want.
3100 Don't #include <libguile.h> here; that generates dependencies on
3101 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
3102 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
3103 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

3200 * weaks.c: Get "weaks.h".
3202 * stackchk.h: #include "libguile/debug.h",
3204 * print.h, read.h: #include "options.h", since everyone who uses
3205 either of these files will need that.
3207 * smob.h: #include "ports.h", "genio.h", and "print.h", since
3208 anyone who uses this file will need them to define the smob
3209 printing functions. Also, get markers.h, since people will need
3210 to #define the mark functions.
3212 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
3213 * ports.h: ... to here.
3215 * ports.h (scm_port_table_size): Explicitly give type as 'int';
3216 don't rely on archaic C default type rules.
3218 * fports.h: #include "libguile/ports.h", since you need that in
3219 order to parse this.
3221 * genio.h: #include "libguile/print.h", because you need that to
3222 parse this; don't bother #including "ports.h", since print.h gets
3225 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
3227 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
3228 this; it's now a reference to an element of *scm_root.
3230 * debug.h: Don't #include "options.h"; the compiler won't be able
3231 to find that once the headers are installed; instead, #include
3232 "libguile/options.h".
3233 * gc.h: Same, with marksweep.h.
3234 * mbstrings.h: Same, with symbols.h.
3235 * scmhob.h: Same, with _scm.h.
3236 * smob.h: Same, with params.h.
3238 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
3239 C files; there's no need for this, and it forces recompilations
3242 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
3244 * error.c (scm_error): declare scm_error_callback.
3246 * error.h: prototype for scm_error_callback.
3248 * __scm.h: define lgh_error.
3249 (SCM_SYSERROR): redefine using lgh_error.
3251 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
3253 * error.c (scm_error): new procedure.
3255 * error.h: prototype for scm_error.
3257 * Makefile.in (install): install scmconfig.h from the current
3258 directory, not $(srcdir).
3260 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3262 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3263 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3264 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

3270 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3271 vports.h, weaks.h: #include "libguile/__scm.h", not
3272 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
3273 dependencies are within libguile properly.
3275 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3277 * Makefile.in (.c.x): Simplify; there's no need to run this rule
3278 when scmconfig.h doesn't exist.
3280 * load.c (scm_sys_try_load): Correct spelling.
3282 * feature.c (scm_loc_features): Make this static.
3284 * Makefile.in (libpath.h): Omit trailing slash from path. We
3285 shouldn't require it of users, so why put it here?
3287 Move code to initialize and search %load-path from ice-9 to C
3288 code, so we can use the load-path to find the ice-9 boot code;
3289 this makes it easier to run Guile without installing it. See
3290 corresponding changes in guile/Makefile.in.
3291 * feature.c: Move stuff concerned with the load path to load.c.
3292 (scm_compiled_library_path): Deleted.
3293 Don't #include libpath.h here.
3294 * feature.h: Don't mention scm_compiled_library_path.
3295 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
3296 <sys/stat.h>, and <unistd.h> (if present).
3297 (R_OK): #define if the system hasn't deigned to.
3298 (scm_loc_load_path): New variable.
3299 (scm_init_load_path, scm_sys_search_load_path,
3300 scm_sys_try_load_path): New functions.
3301 (scm_init_load): Initialize scm_loc_load_path to point to the
3302 value cell of the Scheme %load-path variable.
3303 * load.h: Add declarations for scm_sys_search_load_path,
3304 scm_sys_try_load_path.
3305 * init.c: Call scm_init_load_path.
3306 * Makefile.in (feature.o, load.o): Dependencies updated.
3308 * load.c, load.h: Rewrite using PROTO macro.
3310 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3312 * gc.c (scm_cellp): New function: C predicate to determine if an
3313 SCM value can be regarded as a pointer to a cell on the heap.
3315 * gc.h: Added declaration of scm_cellp.
3317 * gdb_interface.h: New file: The GDB interface header from the GDB
3320 * gdbint.c: New file: GDB interface.
3322 * gdbint.h: New file: GDB interface.
3324 * libguile.h: Added #include <libguile/gdbint.h>.
3326 * init.c (scm_boot_guile): Added scm_init_gdbint.
3328 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
3329 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
3330 found if object files and source are kept separate).
3332 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
3334 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
3336 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
3338 * configure.in: Don't substitute the values of TCL_SRC_DIR and
3339 TK_SRC_DIR; they're not relevant any more.
3341 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
3342 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
3344 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
3346 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
3347 search path, so we can find the <libguile/MUMBLE.h> headers.
3349 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
3351 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
3352 implicit in the .c.o rule.
3353 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
3356 Put the library path in a header file, instead of passing it on
3357 the command line in every compilation.
3358 * Makefile.in (libpath.h): New target.
3359 (feature.o): Depend on libpath.h.
3360 (clean): Delete libpath.h.
3361 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
3362 * feature.c: ... #include "libpath.h" here.
3363 * .cvsignore: Ignore libpath.h.
3365 Don't install the unwashed masses of Guile header files in the
3366 main #include path; put most of them in a subdirectory called
3367 'libguile'. This avoids naming conflicts between Guile header
3368 files and system header files (of which there were a few).
3369 * Makefile.in (pkgincludedir): Deleted.
3370 (innerincludedir): New variable; this and $(includedir) are enough.
3371 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
3372 (installed_h_files): Divide this up. Now this variable lists
3373 those header files which should go into $(includedir) (i.e. appear
3374 directly in the #include path), and ...
3375 (inner_h_files): ... this new variable says which files appear in
3376 a subdirectory, and are referred to as <libguile/mumble.h>.
3377 (h_files): List them both.
3378 (install): Create innerincludedir, not pkgincludedir. Put
3379 the installed_h_files and inner_h_files in their proper places.
3380 (uninstall): Corresponding changes.
3381 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3382 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3383 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
3384 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
3385 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
3386 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
3387 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
3388 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
3389 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3390 vports.h, weaks.h: Find __scm.h in its new location.
3391 * __scm.h: Find scmconfig.h and tags.h in their new locations
3392 (they're both "inner" files).
3394 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
3396 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
3398 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3400 * posix.c: Doc fixes.
3402 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
3404 * socket.c: Don't include a prototype for inet_aton; just use a
3405 K&R style declaration, to avoid warnings but minimize the chance
3406 of conflicts with the system.
3408 On NextStep, <utime.h> doesn't define struct utime, unless we
3409 #define _POSIX_SOURCE before #including it.
3410 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
3411 * acconfig.h: New comment text for above CPP symbol.
3412 * configure.in: Call it.
3413 * posix.c: #define _POSIX_SOURCE if it seems necessary.
3415 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
3417 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
3418 testing for __EMX__.
3420 * posix.c: #include <libc.h>, if it exists.
3422 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
3423 don't even know if the latter exists.
3425 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
3426 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
3427 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
3429 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
3431 (scm_init_posix): Use them when initializing the Scheme constants
3434 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3436 * Makefile.in (libdir, includedir, bindir): Use the
3437 autoconf-supplied values, instead of deriving them ourselves.
3438 (pkgincludedir, datadir, pkgdatadir): New variables.
3439 (install, uninstall): Put the header files in a special
3440 subdirectory, not in the main search path.
3442 * Makefile.in (ALL_CFLAGS): Provide the proper value for
3443 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
3445 * Makefile.in (IMPLPATH): Deleted; never used.
3447 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
3448 on the Tcl/Tk source any more.
3449 (INCLUDE_CFLAGS): Remove references to the above.
3451 * Makefile.in (version.o): Corrected dependencies.
3453 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
3455 * libguile.h: #include "version.h"
3457 * init.c (scm_boot_guile): Call scm_init_version.
3458 * gscm.c (gscm_run_scm): Call scm_init_version.
3460 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
3461 GUILE_VERSION): AC_DEFINE these.
3462 (acconfig.h): #undef the above symbols.
3464 * Makefile.in (libobjs): Add version.o.
3465 (installed_h_files): Add version.h.
3466 (c_files): Add version.c.
3467 (gen_c_files): Add version.x.
3468 (version.o): New rule.
3469 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
3470 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
3471 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
3472 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
3473 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
3474 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
3475 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
3476 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
3477 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
3478 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
3479 weaks.o): Add version.h to dependency lists.
3480 (markers.o): Remove duplicate rule.
3482 * version.h: New file.
3484 * version.c: New file.
3486 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3488 * symbols.c (scm_strhash): scm_downcase is now a function, not an
3489 array; use it appropriately. Since GCC is quite happy to
3490 subscript functions, it never warned us about this; we should use
3491 -Wpointer-arith in the future. I guess we never tested
3494 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3496 * socket.c: Doc and copyright fixes.
3498 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3500 * debug.c: Fixed and improved gdb support.
3502 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3504 * socket.c: Added declaration of inet_aton to avoid compiler
3505 warning. (Hope this solution is correct.)
3507 * stime.c: Added declaration of ftime. (This is missing in
3510 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
3512 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3514 * Makefile.in (c_files): add strerror.c.
3516 * strerror.c: new file from Emacs' sysdep.c.
3517 maybe configure should also check for sys_errlist.
3519 * configure.in (AC_REPLACE_FUNCS): add strerror.
3521 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3523 * debug.c (scm_init_debug): Added initialization for
3524 scm_evaluator_traps.
3526 * debug.h, debug.c: Various name changes.
3527 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
3528 "debug-options-interface". See commentary in options.c.
3530 * options.h, options.c: Options now have documentation strings.
3531 Also added a long explanatory commentary.
3533 * eval.c, print.h, print.c, read.h, read.c: Modifications to
3536 * gscm.c, init.c, root.c, throw.c: Bug fixes:
3537 last_debug_info_frame is now updated in all cases.
3539 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
3542 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3544 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
3545 Added option STACK_CHECKING.
3547 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3549 * Makefile.in: Added {debug,options,srcprop}.{h,c}
3551 * __scm.h: Removed symbols for debugging support.
3553 * acconfig.h: Added symbols for debugging support.
3555 * configure.in: Added user option for debugging support.
3556 --enable-debug will include the debugging code into libguile.a.
3558 * continuations.c (scm_make_cont): Enlarged the #if 0 around
3559 scm_relocate_chunk_to_heap.
3561 * debug.c: New file: low-level debugging support. It also
3562 includes support for debugging with gdb. (The extensions to gdb
3563 are written by Per Bothner at Cygnus.)
3565 * debug.h: New file: low-level debugging support.
3567 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
3568 argument pairs. Extensive modifications to the debugging
3569 evaluator. Added "SECTION:" commentaries to clarify what happens
3570 when, during double compilation. Renamed EVALIMP --> EVALIM.
3571 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
3572 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
3573 the beginning of the file. New procedure: scm_unmemocopy.
3574 Added some global state variables needed by the debugging
3575 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
3576 check_entry, check_apply, check_exit, debug_options and
3577 evaluator_traps. New acro: undefine.
3579 * eval.h: Renamed EVAL --> XEVAL.
3581 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
3582 --> scm_make_weak_key_hash_table.
3584 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
3585 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
3587 * libguile.h: Conditionally include debug.h
3589 * objprop.c (scm_object_properties, scm_set_object_properties_x):
3590 scm_object_properties shouldn't return handle. `handle' now gets
3591 initialized in scm_set_object_properties_x. scm_object_properties
3592 doesn't any longer create an entry in scm_object_whash.
3594 * options.c: New file: handling of run time options.
3596 * options.h: New file: handling of run time options.
3598 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
3600 * print.c: New procedure: scm_print_options
3602 * print.h: Defines for print options.
3604 * read.c: New procedure: scm_read_options
3606 * read.h: Defines for reader options.
3608 * root.h: Added scm_source_whash among scm_sys_protects.
3610 * srcprop.c: New file: source properties.
3612 * srcprop.h: New file: source properties.
3614 * throw.c (jbsmob): Jump buffers are now correctly allocated.
3615 (Bug found by A. Green.)
3617 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3619 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3621 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
3623 * libguile.h: #include "objprop.h"; I guess this was forgotten.
3625 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
3626 and should be called by the final client.
3628 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
3630 * gc.h: Use the PROTO macro when declaring functions.
3631 * gc.c: Use the PROTO macro when declaring static functions.
3632 Remove the CPP hair around function definitions.
3634 * gc.c (scm_init_storage): Initialize scm_asyncs.
3636 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
3637 preprocessor symbol; "__scm.h" is where it might get #defined.
3638 * __scm.h: Similar: #include <scmconfig.h> before testing
3641 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
3643 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
3645 * init.c (scm_boot_guile): Add init_func argument; call
3646 (*init_func) instead of calling scm_appinit; it's ucky to
3647 hard-code names for the user's procedures.
3648 * init.h (scm_boot_guile): Adjust declaration.
3650 * __scm.h (PROTO): New macro, for declaring functions with
3653 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
3654 eliminate all the __STDC__ conditionals.
3655 (scm_boot_guile): Add declaration.
3656 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
3657 Remove __STDC__ conditionals around function definitions; the
3658 declarations in init.h will provide the same information, more
3661 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
3662 complain about it in the error message; the error message is
3663 adequate without that note, and there's nothing the user can do
3666 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
3668 * Makefile.in (ancillary): Drop def.sed.
3670 * posix.c (scm_init_posix): Use numeric values, rather than
3671 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
3672 F_OK. The symbols aren't available on some systems, and I'm
3673 pretty sure their values are fixed by common widespread practice.
3674 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
3676 More functions unavailable on some systems.
3677 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
3678 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
3680 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3681 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
3682 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
3683 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
3684 stub that signals an error as the #else.
3686 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
3688 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
3690 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
3692 * unif.c: include ramap.h.
3694 * read.c (endif): case_insensative_p renamed case_insensitive_p.
3696 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
3698 * ports.c: include sys/ioctl.h.
3700 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
3702 * configure.in: check for sys/ioctl.h.
3704 * ports.c: include <malloc.h> not "malloc.h".
3706 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3708 * fports.c: remove ttyname and tmpnam declarations.
3710 * posix.c: fewer ttyname declarations.
3712 * fports.c: include <string.h> not "string.h".
3714 * init.c, ioext.c: include string.h and unistd.h.
3716 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
3718 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
3719 genio.c, simpos.c, vports.c: include string.h.
3721 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
3723 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
3725 (scm_addr_buffer_size): change type from scm_sizet to int.
3726 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
3727 from scm_sizet to int.
3729 * error.c: include unistd.h.
3731 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
3734 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
3736 * __scm.hd, def.sed: deleted.
3738 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
3740 Changes for NeXT, suggested by Robert Brown.
3741 * configure.in: Call AC_TYPE_MODE_T.
3742 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
3743 NeXT. Put header file list in alphabetical order.
3744 * configure, scmconfig.h.in: Regenerated.
3745 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
3747 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
3750 * acconfig.h: New file, providing documentation for the CPP
3751 symbols defined in configure.in
3752 * acconfig-1.5.h: Removed; superceded by the above.
3754 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
3756 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
3758 * fports.c (scm_open_file): don't return #f, throw error.
3760 * ioext.c (fileno): renamed from %fileno.
3761 (soft-fileno): deleted.
3763 * ports.c (scm_port_revealed): don't need to check for -1 from
3765 (scm_set_port_revealed_x): return unspecified, not #f.
3767 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
3769 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
3771 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
3773 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
3775 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3777 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
3778 This is necessary on Ultrix, and doesn't hurt portability.
3780 * Makefile.in (dist-dir): New target, implementing a new dist system.
3781 (installed_h_files): Put in alphabetical order.
3782 Remove duplicate entries for markers.h and unif.h.
3783 (c_files): Remove duplicate entries for markers.c.
3784 (ancillary): Renamed from anillery; all uses changed. Remove
3785 PLUGIN; it's a directory, and needs special treatment in dist-dir.
3786 Remove all the ../doc/* files; doc/Makefile.in handles that.
3788 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
3790 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3791 every if must have an else, or else the whole command has a
3792 non-zero exit code whenever the if's condition is false.
3794 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
3796 * posix.c: include string.h.
3798 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
3800 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
3803 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
3804 Remove leading % from scheme names.
3805 Do not return error values, call SCM_SYSERROR or similar.
3807 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
3809 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
3811 * struct.c (scm_init_struct): new file.
3813 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
3815 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
3816 (scm_list_head): added list-head for rapidly chopping argument
3817 lists off of longer lists (and similar).
3819 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
3821 * objprop.c (scm_object_property): assq the cdr of the whash
3822 handle for obj, not the handle itself.
3824 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
3826 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
3827 weak hash tables last of all marking to avoid an obscure gc bug.

3881 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
3882 handled correctly (SCM_FREEP was applied to them) -- test for

4051 initialization to fix a race condition.
4053 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

4077 set the multi_byte flag correctly in symbols. This is wrong.
4078 intern_obbary_soft and msymbolize should take an extra parameter.

4080 The weird symbol syntax is also a bit bogus (emacs doesn't quite
