1 Mon Jul 21 04:03:42 1997 Gary Houston <ghouston@actrix.gen.nz>
3 * ioext.h: removed scm_duplicate_port prototype.
5 * ioext.c (scm_primitive_dup2): return the new file descriptor
6 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
8 (scm_fdopen): bug fix: don't try to make port unbuffered until its
10 (scm_duplicate_port): deleted, there's now an implementation in
12 (scm_primitive_dup2): do nothing if newfd == oldfd.
14 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
16 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
19 * ioext.h: new prototypes.
20 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
22 * fluids.c (next_fluid_num): don't do
23 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
25 * ports.h: prototypes too.
26 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
28 * fports.h: prototype too.
29 * fports.c (scm_evict_ports): moved from ioext.c.
31 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
33 * ports.c (scm_close_port): return a boolean instead of unspecified.
34 throw an error if an error other than EBADF occurs.
36 * filesys.h: scm_close prototype.
37 * filesys.c (scm_close): new procedure, can close file descriptors
38 and ports (scsh compatible).
40 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
43 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
45 * fluids.c, fluid.h: New files.
46 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
47 (modinclude_HEADERS): Added "fluids.h"
49 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to
50 scm_init_fluids to initialize the fluid machine.
51 (scm_start_stack): Initialize the fluids of the first root with
52 scm_make_initial_fluids.
54 * root.h: Added "fluids" member to scm_root_state.
55 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
56 (scm_make_root): Call scm_copy_fluids to make fluid bindings
57 unique for the new root when it has a parent.
59 * smob.h: Include "libguile/print.h" to make scm_print_state
62 * dynl.c (free_dynl_obj): New function to free the dynamic object
63 data. (dynl_smob): Use it.
64 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
65 the dynamic object data below the linking of the object to avoid
66 memory leak when the linking code throws an error. Now the code
67 leaks a whole dynamically linked library when must_malloc throws,
68 but that should be much less likely.
70 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
72 Changes to compile under gnu-win32, from Marcus Daniels:
73 * stime.c (tzset): If tzset isn't provided, make it a NOP.
74 (scm_localtime): Change SCM_EOF to SCM_EOL.
75 (scm_mktime): Likewise.
76 * socket.c: Don't include sys/un.h unless autoconf tells
77 us Unix domain sockets are available.
78 (scm_fill_sockaddr): Ignore Unix domain code.
79 (scm_addr_vector): Likewise.
80 (scm_init_addr_buffer): Likewise.
81 (scm_socketpair): Don't include unless socketpair was
82 found during autoconf.
83 * simpos.c (SYSTNAME): Treat cygwin like Unix.
84 * scmsigs.c (scm_pause): Don't include unless pause was found
86 * posix.c (scm_getgroups): Don't include unless support function
87 was found during autoconf (in this case, getgroups).
88 (scm_setpwent): For setpwent.
89 (scm_setegid): For setegid.
90 * net_db.c (scm_inet_netof): Don't include unless support
91 function was found during autoconf (in this case, inet_netof).
92 (scm_lnaof): For inet_lnaof.

105 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
106 scm_misc_error, not SCM_EOF.
108 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
109 arguments for formatting the error message, not SCM_BOOL_F. I
110 think this is left over from the (eq? '() #f) days.
112 * read.c (recsexpr): Give this a dummy definition if
113 DEBUG_EXTENSIONS isn't #defined.
115 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
117 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
120 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>
122 * root.c (cwdr_outer_body): Bugfix: Pass `c' instead of `&c' to
125 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
127 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
128 alloca.lo will be included in @LIBLOBJS@. Something better than
129 this should be possible.
130 * Makefile.in: Regenerated.
132 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
134 * simpos.h: prototype for scm_primitive_exit.
135 * simpos.c (scm_primitive_exit): new procedure, terminates the
136 process without unwinding the stack.
138 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
140 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
141 argument and logior its components together, so the user doesn't
142 have to do this explicitly. Also, if regexp/basic is supplied, then
143 turn off REG_EXTENDED.
144 (scm_init_regex_posix): New regexp/basic symbol.
145 (REG_BASIC): #define this if it is not already present.
147 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
149 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
150 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
151 (CLEANFILES): New target, clean versiondat.h, libpath.h.
152 (DISTCLEANFILES): New target, clean *.x.

161 * Makefile.in: Regenerated.
163 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
164 flag; I don't think we support it.
165 (scm_make_regexp): Make sure the user doesn't pass the
168 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
170 (scm_init_regex_posix): Define constants for the REG_mumble flags;
171 name them according to the SCSH convention: regexp/mumble.
173 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
175 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
177 * Makefile.am (libpath.h): Include the values of all the standard
178 Makefile directory variables. Print a message, but don't print

181 * load.c: #include "alist.h".
182 (init_build_info): New function.
183 (scm_init_load): Call it.
184 * Makefile.in: Regenerated.
186 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
188 * root.c: Establish a reliable catch-all handler for the new root.
189 After all the Scheme handler function might signal an error too,
190 and we don't want to lose that.
191 (cwdr_inner_body): Renamed from cwdr_body.
192 (cwdr_outer_body): New function, to establish the user's handler,
193 and pass control to cwdr_inner_body.
194 (cwdr): Establish the reliable catch-all handler here, and pass
195 control to cwdr_outer_body.
196 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
197 the user's handler through to cwdr_outer_body.
198 * throw.c (scm_handle_by_message): Move guts into....
199 (handler_message): New static function.
200 (scm_handle_by_message_noexit): New function.
201 * throw.h (scm_handle_by_message_noexit): New prototype.
203 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
204 across this. Only works on GCC. Otherwise, we hope for the best.
205 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
206 the feeling that real thread systems will not need this...
208 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
210 Try to detect when people are using one version of libguile and a
211 different version of ice-9. People have been skewing things and
212 sending in bug reports.

214 * version.c: #include "versiondat.h", to get version info.
215 (scm_libguile_config_stamp): New function.
216 * script.c: #include "version.h".
217 (scm_compile_switches): Call scm_version to get version number.
218 * scmconfig.h.in, Makefile.in: Regenerated.
219 * Makefile.in: Regenerated.
221 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
222 primitive definitions under their Scheme names.
224 * Makefile.am (libguile_la_LDFLAGS): Update library version to
225 1:2. Helps avoid confusion between installed and uninstalled libs.
227 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
230 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
231 backslash from definition; this should be used like: GDB_INTERFACE;
233 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
235 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
236 new port unbuffered until its stream has been set.
238 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
240 * ports.h: new prototype.
241 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
243 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
245 Make things compile neatly under Sun's C compiler.
246 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
247 * extchrs.c (xmbtowc): Make the second arg a normal char, not
248 unsigned, because that's what the ANSI function takes.
249 * extchrs.h (xmbtowc): Corresponding change to prototype.
250 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
252 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
253 argument plain char *.
254 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
256 * tag.c (scm_tag): Remove unreachable statement.
257 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
258 top of the word, it should be unsigned.
260 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
261 is defined, to avoid warnings; it's only used in the
262 conflict-checking code. Which might go away anyway.
263 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
264 conditionals; put the label definition in an #if too, to stifle
267 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
268 ChangeLog-threads in the distribution.
269 * Makefile.in: Regenerated.
271 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
273 * guile-snarf.in: Changed regexp to support CPPs that insert
274 whitespace between lexical tokens (which munges the `%%%' snarf

279 * load.c (scm_init_load_path): Append $(datadir)/guile to
280 %load-path, so modules do not have to be installed in Guile's
281 current version directory.
283 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
285 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
286 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
287 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
288 call the sysdep functions with deferred ints.
289 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
290 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
291 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
294 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
297 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
299 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
301 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
303 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
306 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
308 * eval.c (scm_lookupcar1): New procedure to cope with a race
309 condition during lookup (when using threads).
310 (scm_lookupcar): Implement in terms of scm_lookupcar1.
311 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
314 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
316 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
317 supplied. (Change from Tim Pierce.)
319 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
321 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
322 23:47:01 1997" changelog: Slots are now initialized with `#f' by
323 default and not `()'. `#f' is the canonical non-value in Scheme,
326 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
328 * struct.c (struct_printer): New variable that holds a handle on
329 the Scheme variable *struct-printer*. This variable can be set by
330 Scheme code to override the printing of structures.
331 (scm_print_struct): If struct_printer is set, call it. If it is
332 not set, or returns #f, print the structure in the old fashion.
333 Include "eval.h" for scm_apply.
335 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
337 * struct.c (scm_struct_ref, scm_struct_set_x): Use
338 scm_struct_i_n_words to get the number of fields, not
339 -scm_struct_n_extra_words.
341 On the route to fancier struct printing:
342 * struct.c (scm_print_struct): New function to print a structure.
343 Include "genio.h" to support it. This function doesn't do
344 anything interesting right now, but I think it should be here
346 * struct.h: Include "print.h" and add prototype for
348 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
349 print structures ourself.
351 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
353 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
354 before applying the handler in case it doesn't return.
356 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
358 * scmsigs.h, async.h: updated.
360 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
363 * posix.c (scm_uname): interpret only negative values as an error.
364 Solaris normally returns a positive value.
366 * script.c (scm_compile_shell_switches): if we are not going into
367 an interactive repl, set scm_mask_ints to zero so that asyncs can
370 * simpos.c (scm_system): don't ignore/unignore signals around
373 * posix.c (scm_open_pipe): don't ignore/unignore signals around
376 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
377 done in boot-9.scm instead.
379 * scmsigs.c, async.c: Major rewriting of signal handling code.
380 (scm_sigaction): new procedure.
381 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
383 (scm_raise): return unspecified, throw error on failure.
385 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
387 * regex-posix.c (scm_init_regex_posix): Register the "regex"
388 feature, to help boot-9.scm decide whether to import the regex
391 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
393 * eval.c: Include scmconfig.h at the beginning of the file so that
394 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
397 * regex-posix.c: #include "_scm.h" before conditionally #including
398 <regex.h>; the former defines HAVE_REGCOMP.
400 * regex-posix.c: #include <regex.h> conditionally, so the file is
401 CPP'able (for dependency scanning) even on systems that don't have
404 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
406 Add new R4RS-compliant syntax for keywords.
407 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
408 regardless of the setting of the `keywords' read option.
409 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
410 can be re-read no matter what the setting of the `keywords' read
413 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
415 Add support for POSIX regular expressions.
417 * regex-posix.c, regex-posix.h: New files. (Some code
418 is taken liberally from rx/rgx.c in the old Guile dist.)
420 * init.c: Include regex-posix.h.
421 (scm_boot_guile_1): Call scm_init_regex_posix.
423 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
424 Add regex-posix.[ch] sources.
425 * Makefile.in: Regenerated.
427 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
428 to do this automatically? It didn't for me, bleh.)
430 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
432 * fports.c (print_pipe_port): New function.
433 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
434 latter doesn't even take the right arguments.
436 * Makefile.am: Increment shared lib revision number. I think
437 sometimes the uninstalled Guile finds the installed shared lib;
438 Gord says doing this might help. As things turned out, I can't
440 * Makefile.in: Regenerated.
442 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
443 passing it as the closure argument to scm_boot_guile. (Bill
446 * ports.c (print_void_port, putc_void_port, puts_void_port,
447 write_void_port, flush_void_port, getc_void_port, close_void_port,
448 noop0): Use ANSI prototypes instead of K&R declarations, so the
449 initialization of void_port_ptob gets aggressively type-checked.
450 Fix arguments of print_void_port and write_void_port. (Bill

486 * script.c (scm_find_executable): Use prototype-style definition
487 here; apparently it's not quite right to have const in a prototype
488 and then use a K&R declaration. I wonder if stuff like this will
489 go away if we compile with -Wrequire-prototypes, or whatever that
490 is... (Bernard URBAN)
492 * scmhob.h: New text from Bernard URBAN.
494 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
496 * script.c: Don't #define const on hpux. Configure takes care of
497 this. (Thanks to Larry Schwimmer.)
499 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
500 decide whether to #include <unistd.h>, instead of listing a bunch
501 of systems. Don't #include stdio twice. Removed dyked-out
502 definition of scm_find_impl_file.
504 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
506 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
507 library version info to 1:0.
508 * Makefile.in: Regenerated.
510 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,
511 gdb_interface.h, gdbint.c, gdbint.h, gh_data.c, gh_init.c,
512 gh_io.c, gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c,
513 init.c, net_db.c, options.c, options.h, ports.c, print.c, read.c,
514 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
515 throw.c: Update copyright years; these files have been worked on
516 significantly in 1997, but only had copyright years for 1996.
517 Also, change name of copyright holder on some from Mikael
518 Djurfeldt to Free Software Foundation; he has signed papers
519 assigning the changes to the FSF.
521 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
522 reason not to give the user the option.
524 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
525 Return #f on end-of-file when scanning table (i.e. when called
526 with no arguments). Try to catch errors, when we can.
527 * posix.c (scm_getgrgid, scm_getpwuid): Same.
529 * script.h (scm_shell_usage, scm_compile_shell_switches): New
530 external declarations. These are useful.
532 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
534 * posix.c: don't include <sys/select.h> or define macros for
535 select, since they were not used in this file.
537 * filesys.c (scm_select): make the fifth parameter microseconds,
538 not milliseconds. let the fourth parameter be either a real value
539 or an integer or #f. The first, second and third arguments can
540 now be vectors: the type of the corresponding return set will be
542 (set_element, get_element): new static procedures.
544 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
546 * strports.c (scm_eval_string): New function.
547 (scm_eval_0str): Trivially re-implemented in terms of
549 * strports.h (scm_eval_string): New extern decl.
551 * net_db.c (h_errno): Add extern decl for this.
553 * fports.c (local_pclose): New function.
554 (scm_pipob): Use it in the initializer here.
557 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
558 Use a meaningful error message when signalling an error. For
559 this, scm_gethost must check h_errno rather than errno.
561 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
563 * Makefile.in: Regenerated, using automake-1.1p.
565 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
567 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
570 * script.c (scm_compile_shell_switches): don't append (quit) if
572 (scm_shell): call scm_exit_status and exit on the result of the
575 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
577 Ensure that shared substrings are handled properly when passed to
578 a system call or other foreign function. Many thanks to Tim
580 * symbols.h (SCM_COERCE_SUBSTR): new macro.
581 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
582 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
583 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
584 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
585 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
586 (scm_display_error_message): use RO macros when strings may be RO.
587 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
588 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
589 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
590 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
591 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
592 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
593 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
594 scm_strftime), vports.c (scm_make_soft_port): use
595 SCM_COERCE_SUBSTR to make sure shared substrings are
598 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
600 * error.c (scm_error): Add newline to error message.
602 * init.c (scm_init_standard_ports): Doc fix.
604 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
606 * dynl-shl.c: Completely replaced with new code from Bernard
609 * script.c (scm_ice_9_already_loaded): New variable.
610 (scm_compile_shell_switches): Use it.
612 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
614 * filesys.c (scm_input_waiting_p): add missing third argument to
617 * stime.c (scm_localtime): copy the result of localtime before
618 calling gmtime in case they share a buffer.
619 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
622 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
624 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
626 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
628 * Makefile.am (check-local): New target, which causes 'make check'
629 to run gh_test_c and gh_test_repl, with some trivial input.
630 * Makefile.in: Rgnrtd.
632 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
634 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
637 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
639 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
640 sure how this was supposed to work.
641 (scm_async_click): don't send SCM_TICK_SIGNAL.
642 (scm_init_async): don't initialize %tick-thunk.
644 * the following change doesn't affect the Scheme interface:
645 gc-thunk is called at the end of garbage collection. however it's
646 no longer implemented by pretending it's a signal.
648 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
649 system async corresponding to scm_gc_thunk.
650 * async.h: declare scm_gc_async.
651 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
652 gc-thunk directly, instead of going through a signal handler.
653 (scm_gc_async): new variable, points to the GC system-async.
654 (scm_init_async): save the GC async as scm_gc_async instead
655 of using system_signal_asyncs.
656 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
658 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
660 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
661 Don't screw up if we're interrupted.
662 * Makefile.in: Regeneradet.
664 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
666 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
668 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
669 we're not using AM_INIT_GUILE_MODULE any more.
670 * Makefile.in: Reneregated.
672 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
674 Functions for finding variable bindings, grace à Tim Pierce.
675 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
676 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
678 Get 'make dist' to work again.
679 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
680 * Makefile.in: Regenerated, like a surry without a fringe on top.
682 Changes for reduced Guile distribution: one configure script,
684 * configure.in, configure: Removed.
685 * acconfig.h, acinclude.m4: Moved to parent directory, where the
686 real configure script lives.
687 * Makefile.in, scmconfig.h.in: Regenerated.
689 * init.c: #include "script.h", to get prototype for script.c's
692 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
694 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
695 scm_must_malloc, not raw malloc.
697 * script.c (scm_compile_shell_switches): Dyke out debugging output
700 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
702 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
704 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
705 system has them. Hope this is safe. Previously
706 sys/timeb.h was included if HAVE_FTIME was defined or if
707 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
708 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
710 * ioext.c (scm_setfileno): add missing third argument to
713 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
715 * eq.c (scm_equal_p): Correctly compare strings of different
716 varieties. (Thanks to Tim Pierce.)
718 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
720 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
721 #! block comment must occur on a line all by itself.
723 Move most of the guts of shell command processing into libguile,
724 so guile.c can be very small (and eventuallly auto-generated. (I
725 mean, generated mechanically, not self-generated. Hmm.))
726 * guile.c, script.c, script.h: New source files.
727 * init.c (scm_boot_guile_1): Call scm_init_script.
728 * libguile.h: #include "script.h".
729 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
730 targets, for new executable.
731 (libguile_la_SOURCES): Mention script.c.
732 (modinclude_HEADERS): Add script.h.
733 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
734 not dynamic linking is enabled. This is because we're generating
735 executables now. Move CY_AC_WITH_THREADS call after those, so the
736 values of cy_cv_threads_libs captures the libs chosen above.
737 * Makefile.in, configure, aclocal.m4: Regenerated.
739 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
740 We don't maintain this interface any more, and it just confuses
743 * alloca.c: #include <scmconfig.h>, not <config.h>.
744 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
745 it'll get included in disties.
747 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
749 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
750 be distributed, because they confuse people.
751 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
753 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
755 * configure.in: check for presence of gethostent (not present on
757 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
758 * configure, scmconfig.h.in: Regenerated.
760 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
762 * backtrace.c (scm_backtrace): Split message string across
763 newlines properly. GCC is more tolerant of this than other
766 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
768 Merge threads directory into libguile.
769 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
770 threads.h: New source files.
771 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
772 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
774 (modinclude_HEADERS): Add threads.h, coop-defs.h.
775 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
776 coop-threads.c.cygnus, coop-threads.h.cygnus.
777 * configure.in: If we're using threads, include threads.o in
779 * _scm.h, libguile.h: threads.h lives in this directory now.
780 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
781 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
782 currently used, but brought along for information's sake.
783 * ChangeLog-threads: log from old 'threads' directory.
784 * Makefile.in, configure: Rebuilt.
786 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
788 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
791 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
793 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
795 Merge GH interface library into libguile.
796 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
797 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
798 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
799 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
801 (EXTRA_libguile_la_SOURCES): ... here.
802 (pkginclude_HEADERS): Add variable, to get gh.h installed.
803 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
804 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
805 New variables, describing how to build the gh test programs.
806 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
807 build the test programs, and we probably should have been linking
808 libguile.la against them all along, to support AIX shared libs.
809 Add cflags for threads to CFLAGS; add libs for threads to new
810 variable THREAD_LIBS, used in Makefile.am.
811 * ChangeLog-gh: log from old `gh' subdirectory.
812 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
814 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
816 * acconfig.h: Undo change of Apr 9; including the definition of
817 PACKAGE in the guile headers conflicts with applications' own
819 * scmconfig.h.in: Regenerated.
821 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
823 * filesys.c (scm_fcntl): New function from Roland McGrath.
824 (scm_init_filesys): New symbols for use with fcntl.
825 * filesys.h: Added prototype.
827 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
828 when PROC is receiving no arguments.
830 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
832 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
833 have S_IFSOCK. This is the case under Ultrix.
835 * posix.c (scm_status_exit_val, scm_status_exit_val,
836 scm_status_term_sig, scm_status_stop_sig): Modified to work with
837 Ultrix versions of WIFSTOPPED, etc., which assume that their
838 arguments are lvalues (hmm).
840 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
844 * throw.c: Doc fixes; rearranged.
846 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
848 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
850 * acconfig.h: Added entry for PACKAGE.
851 * scmconfig.h.in: Regenerated.
853 Changes to work with automake-1.1n, which has better libtool support.
854 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
855 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
857 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
859 * Makefile.in: Rebuild.
861 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
863 * stime.c (scm_mktime): take an optional zone argument.
864 (scm_localtime): check putenv return value.
865 (scm_strftime, scm_strptime): moved from posix.c. move #include
867 stime.h, posix.h: update prototypes.
868 (bdtime2c, setzone, restorezone): new static procedures.
869 (scm_mktime, scm_strftime): use them.
870 (scm_strftime): don't call mktime before strftime. Use
871 filltime for return value.
872 (filltime): convert NULL zname to #f.
873 (scm_strptime): return a count of characters consumed, not
874 the remaining string.
876 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
878 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
879 (scm_mktime): likewise.
881 Uncomment localtime and mktime.
883 * configure.in: add AC_STRUCT_TIMEZONE.
885 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
887 * stime.c (scm_init_stime): don't define ticks/sec.
888 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
889 return value problem and is still portable.)
891 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
893 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
894 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
895 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
896 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
897 cpp_err_symbols.c): Corresponding changes.
898 * Makefile.in: Regenerated.
900 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
902 * posix.c (scm_putenv): don't check HAVE_PUTENV.
903 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
904 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
905 * putenv.c: new file, from sh-utils 1.12.
907 * posix.c (scm_environ): use malloc in place of scm_must_malloc
908 since allocation isn't for Scheme objects.
909 (scm_putenv): copy strings before placing in the environment.
911 * stime.c (scm_current_time): throw an error if time returns -1,
912 instead of returning #f.
913 (scm_get_internal_real_time, scm_get_internal_real_time): use
914 scm_long2num for return value instead of SCM_MAKINUM.
916 * stime.h: prototypes updated.
918 * stime.c (scm_time_in_msec): apparently unused, deleted.
920 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
922 * configure.in: check for gettimeofday.
924 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
925 which may be more usefully portable than a gettimeofday interface.
927 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
929 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
931 * Makefile.in: Regenerated.
933 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
935 * stime.c (filltime): recovered static procedure.
936 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
939 * posix.h: add prototype for scm_close_pipe, remove prototypes for
940 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
942 * posix.c (scm_mknod): split the mode argument into type and perms
943 arguments, like the extra fields returned by stat.
945 * fports.c (scm_pipob): set the close, free and print procedures.
946 (scm_close_pipe): new procedure.
948 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
949 define them in boot-9.scm
951 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
953 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
954 wan't defined. Don't include fd.h.
956 * Previously fd.h was regenerated whenever configure was run,
957 forcing a couple of files to be recompiled.
959 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
960 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
961 Check for _fileno as well as _file.
963 * ioext.c: don't fd.h.
964 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
967 * Change the stratigy for getting information about errno
968 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
969 generating lists of symbols during the build process, which will
970 not always work, include comprehensive lists in the distribution.
971 To help keep the lists up to date, the "check_signals" and
972 "check_errnos" make targets can be used.
974 * configure.in: don't check for a command to extract errno codes.
975 * Makefile.am: update file lists, remove errnos.list and errnos.c
976 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
977 check_errnos targets.
978 (CLEANFILES): remove errnos.c and errnos.list, add
979 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new

981 * errnos.default: deleted.
982 * cpp_signal.c: new file.
983 * cpp_errno.c: renamed from errnos_get.c.
984 * cpp_err_symbols, cpp_sig_symbols: new files.
985 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
986 * error.c (scm_init_error): #include cpp_err_symbols instead of
988 * posix.c (scm_init_posix): don't intern signal symbols. #include
991 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
993 * strop.c (scm_i_index): allow the lower bound to be equal to the
994 length of the string, so a null string doesn't always give an error.
996 * posix.h: new prototypes.
997 * posix.c (scm_status_exit_val, scm_status_term_sig,
998 scm_status_stop_sig): new functions, as in scsh. They break down
999 process status values as returned by waitpid.
1001 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
1003 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
1004 configure doesn't know about it.
1006 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1008 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
1010 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
1011 which defines C variables with global linkage.
1013 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1015 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
1018 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
1020 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
1021 has time to check why this doesn't work well with continuations.
1023 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
1025 * Fix shell syntax error; some shells won't tolerate
1026 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
1028 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
1030 * posix.c (scm_uname): throw an error if uname fails instead
1033 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
1035 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
1038 * async.c (scm_ints_disabled): definition moved from error.c.
1040 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1042 * acconfig.h: Removed PACKAGE.
1044 * scmconfig.h.in: Regenerated.
1046 * snarf.h: g++ says it's non-portable not to specify the first
1047 argument in a varargs declaration. I introduced the first
1048 argument by using preprocessor conditionals.
1050 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
1052 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
1053 (scm_freopen): use RO string macros for filename and modes.
1054 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
1056 * posix.c (scm_getgrgid): simplify conversion of name to C string.
1057 (scm_mknod): use RO string macros for path.
1059 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
1060 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
1062 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
1063 use SCM_ROSTRINGP and SCM_ROCHARS.
1065 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1067 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
1070 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
1071 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
1072 support for byte vectors.
1074 * print.c (scm_iprin1): Limit number of vector elements printed
1075 according to pstate->length.
1077 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
1079 * backtrace.c (scm_display_error_message): don't segv if message
1082 * error.h: prototype for scm_error_scm.
1084 * error.c (scm_error_scm): new procedure, reimplements scm-error
1085 in C and uses scm_error.
1087 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
1089 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
1090 pointer to the Scheme variable read-hash-procedures and intern it
1091 in scm_init_read. Modify scm_read_hash_extend and
1092 scm_get_hash_procedure to use the pointer.
1094 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1096 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
1097 (SCM_KEYWORD_STYLE): defined.
1099 * read.c (scm_read_opts): add a keywords option. This isn't a
1100 boolean option, in case someone wants to add support for DSSSL
1102 Setup scm_keyword_prefix symbol.
1103 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
1105 I've left keyword support disabled by default, since it doesn't
1106 seem to break the module system and it gives R4RS standard behaviour.
1107 It can be reactivated with (read-set! keywords 'prefix).
1109 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1111 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
1112 before constructing arbiter.
1114 * eval.c (scm_m_define): Bugfix: Check that the object is a
1115 closure before setting the procedure property!
1117 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
1119 * ports.c: Removed `ungetc-char-ready?'.
1121 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
1123 * read.c (scm_init_read): intitialise scm_read_hash_procedures
1124 (idea from Mikael: make it a pair so scm_permanent object only
1126 (scm_read_hash_extend): don't call scm_permanent_object.
1127 (ideas from Mikael): if chr is already in the list, replace its
1128 procedure instead of appending it again. If proc is #f, remove
1130 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
1132 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
1134 * gdbint.c (gdb_read): update scm_lreadr usage.
1136 * load.h: update prototypes.
1138 * load.c (scm_primitive_load, scm_read_and_eval_x,
1139 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
1141 * read.h: add prototype for scm_read_hash_extend. Change args for
1144 * read.c (scm_read_hash_procedures): new variable.
1145 (scm_read_hash_extend): new procedure.
1146 (scm_get_hash_procedure): new procedure.
1147 (scm_lreadr): use scm_get_hash_procedure instead of an argument
1148 for extended # processing.
1149 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
1150 scm_read_token): remove case_i, sharp arguments. Change callers.
1152 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
1154 * read.h (SCM_N_READ_OPTIONS): increase to 3.
1155 (SCM_CASE_INSENSITIVE_P): define.
1157 * read.c: add case-insensitive option to scm_read_opts.
1158 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
1159 to determine whether to convert symbol case.
1160 (default_case_i): definition removed.
1161 * read.c (scm_read_token): if case_i, downcase ic before doing
1164 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1166 * configure.in: Added configuration option `guile-debug'.
1167 Configure with --enable-guile-debug if you want a bunch of extra
1168 functions used for debugging when developing Guile.
1170 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
1172 * procs.c (make-cclo): New undocumented debugging procedure: Make
1173 compiled closure with internal procedure PROC and length LENGTH.
1174 Only compiled if GUILE_DEBUG is defined.
1176 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
1178 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
1180 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
1182 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
1183 with 3 or more args internally to the evaluator.
1185 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1187 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
1188 with 3 or more args internally to the evaluator. This is mainly
1189 because we don't want to pass entry and exit points of the
1190 debug support twice, but it also seems to increase the speed of
1191 the evaluator for such calls (e. g. (+ 1 2 3)).
1193 * backtrace.c (scm_display_application): New procedure:
1194 display-application; Set fancy printing parameters individually
1195 for different types of display (backtrace, error, application).
1196 (These should of course be customizable!)
1198 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
1199 clear the CHECK-flags.
1201 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1203 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
1205 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1207 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
1208 from pairs with a GLOC in the car.
1210 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
1211 otherwise `symbol-hash' will behave badly.
1212 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
1213 we get segmentation fault!
1215 * symbols.c: Added #include "weaks.h". New functions:
1216 `builtin-bindings' and `builtin-weak-bindings'. (These will be
1217 moved to an extraneous library when we split libguile.)
1219 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1221 * filesys.c (scm_stat): stat now takes fport arguments too as
1222 documented in the manual.
1224 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1226 * debug.c (scm_single_step): Bugfix: Call continuation with
1227 scm_call_continuation instead of throwing to it.
1229 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
1231 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
1232 argument wasn't declared to be optional.
1234 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1236 * stime.c (scm_init_stime): Add feature "current-time".
1238 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
1240 * throw.h: prototype for scm_exit_status.
1241 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
1242 args to derive an exit status. Allows (quit) to work from a
1244 (scm_exit_status): new function.
1247 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1249 * eval.c (scm_deval): Removed some old code.
1250 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
1252 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
1255 * symbols.c (msymbolize): Bugfix: Must initialize property list to
1258 * procs.c: Introduce the existent C function scm_thunk_p at the
1259 Scheme level as well.
1261 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1263 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
1264 used from C to easily lookup the value of a symbol in the current
1267 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1269 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
1270 scm_init_unif in this file. This will also fix a previous problem
1273 * configure.in: Added AM_MAINTAINER_MODE
1275 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1277 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
1280 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1282 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
1283 source files that are not always included in libguile but should
1284 have their dependencies calculated by automake. This variable is
1285 recognized by automake, no further magic is needed.
1286 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
1287 to deal exclusively with *.lo files, as it seems. The *.o files
1288 are built automatically when the corresponding *.lo file gets
1291 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
1293 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
1296 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
1298 * unif.c (scm_array_set_x): minor change to argument error checking.
1300 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
1302 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
1303 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
1304 They should only be included in the library at configure.in's
1306 (libguile_la_LDADD): Include the appropriate .lo files here.
1307 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
1308 so we know when to build them (and their .lo bretheren).
1309 * configure.in (LIBLOBJS): New substituted variable. We let
1310 configure decide which .o files to include in LIBOBJS, and then
1311 put the corresponding list of .lo files in LIBLOBJS. The latter
1312 is what we pass to libtool.
1313 * Makefile.in, configure: regenerated.
1315 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
1317 * symbols.c (scm_sysintern0): New function. Contains the core of
1318 old scm_sysintern but doesn't take a second value argument.
1319 (scm_sysintern): Now uses scm_sysintern0.
1320 (scm_sysintern_no_module_lookup): Renamed to
1321 scm_sysintern0_no_module_lookup and doesn't take a second value
1322 argument any longer.
1324 * symbols.h (scm_sysintern0: Added declaration.
1326 * options.c (scm_init_opts): Use scm_sysintern0 instead of
1327 scm_sysintern when interning option keys. Otherwise we risk
1328 destroying the values of already interned variables.
1330 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
1331 scheme-level boolean (use SCM_NFALSEP).
1333 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
1335 (scm_backtrace): New function. (C version of old function from
1336 boot-9.scm) Motivation: Make it possible to display backtraces
1337 without depending on boot-9.scm. (I'm uncertain if this
1338 motivation is good enough...)
1340 * root.h (scm_root_state): Add member the_last_stack_var.
1341 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
1343 * root.c (mark_root): Mark scm_the_last_stack_var.
1345 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
1348 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
1350 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
1351 1. mark_lazy_catch didn't mark the smob.
1352 2. Both functions above have standard variants:
1353 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
1354 free_lazy_catch --> scm_free0.
1356 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
1358 * throw.c (scm_internal_lazy_catch): New function.
1359 (scm_lazy_catch): Rewritten to use it.
1360 (scm_ithrow): Handle the new lazy catch representation.
1361 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
1362 that doesn't have a jmpbuf is a lazy catch clause.
1363 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
1364 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
1365 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
1367 (scm_init_throw): Register the new lazy-catch smob type.
1368 * throw.h (scm_internal_lazy_catch): decl for new function.
1370 * throw.c (scm_internal_catch): Doc fixes.
1372 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
1373 configure.in. Including this might cause problems if applications
1374 that link against libguile include their own copies of alloca, but
1375 if they're using autoconf, they should be adding libguile to LIBS
1376 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
1377 the copy in libguile, and things will be okay. (I think.)
1379 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1381 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
1383 strop.h: move prototypes too.
1385 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
1387 * posix.c (scm_init_posix): don't intern EINTR since it's now done
1390 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
1391 etc. I deleted them from filesys.c long ago, but didn't
1392 notice they were here too (although ineffective since
1393 sys/stat.h wasn't included).
1395 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
1397 * eval.c: Don't define alloca in GCC case. gcc will automatically
1398 use __builtin_alloca if appropriate.
1400 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1402 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
1403 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
1404 that values of automatic variables are preserved. See comments
1405 for safe_setjmp for details.
1407 Change from Thomas Morgan:
1408 * variable.c: Include eq.h.
1409 (var_equal): New function.
1410 (variable_smob): Use var_equal as the discriminator for variables.
1412 * throw.c (s_throw): Remove extraneous declaration.
1414 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
1415 * eval.c: Add necessary CPP cruft to support that.
1416 * configure, Makefile.in, scmconfig.h.in: regenerated.
1418 Change from Thomas Morgan:
1419 * procprop.c (scm_procedure_properties): Convert the Scheme
1420 boolean returned by scm_procedure_p into a C boolean before using
1421 it as a condition for SCM_ASSERT.
1422 (scm_procedure_property): Likewise.
1424 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
1425 indications of Unixness.
1428 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
1430 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
1432 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
1434 * read.c (scm_lreadr): use scm_misc_error to improve one of the
1435 "unknown # object" error messages.
1437 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
1438 (scm_i_index) and declare it static. Add a 'direction' argument
1439 to indicate what way the search should go.
1440 (scm_i_index): throw out-of-range error instead of wrong-type-arg
1442 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
1443 strop.h: remove scm_i_index, scm_i_rindex prototypes.
1445 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
1447 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
1449 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
1450 to avoid clash with various scsh forks.
1452 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
1454 The following two changes (ramap.c, throw.c) are motivated by the
1455 apparent unportability of forward declarations of static arrays of
1456 the form `static foo bar[];'.
1458 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
1459 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
1461 * throw.c (scm_throw): Moved above scm_ithrow.
1463 * options.h: Removed the extern declarations of scm_yes_sym and
1464 scm_no_sym since these are static.
1466 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1468 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
1470 * Makefile.am: remove AWK=@AWK@.
1471 Add a rule for generating errnos.list.
1472 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
1474 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
1475 don't extract errnos, just set a variable (avoids the
1476 need to recompile error.c just because configure is run.)
1478 * unif.h: update prototypes.
1479 * unif.c (scm_uniform_array_read,write): change the offset and
1480 length arguments to start and end, for consistency.
1482 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
1484 * ioext.h: update prototypes.
1485 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
1486 scm_read_line_x, it's a more general procedure using an
1487 interface from scsh. read-line and read-line! are now defined
1489 Note that the new read-line trims the terminator
1490 by default, previously it was appended to the returned string. An
1491 optional argument specifies how to process the terminator (scsh
1492 compatible). For the old behaviour: (read-line port 'concat).
1493 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
1494 returns a pair, but is converted to multiple values if the scsh
1497 socket.h: update prototypes.
1498 * socket.c (scm_recvfrom): for consistency with other procedures,
1499 take start and end as separate optional arguments.
1500 (scm_recv, scm_recvfrom): don't allow the second argument
1501 to be a size, only a buffer. Change the scheme names to
1502 recv! and recvfrom!. Don't return the buffer.
1504 * ioext.h, posix.h: move prototypes too.
1505 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
1506 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
1507 "read.h" and "unif.h".
1508 * ioext.c: include "chars.h"
1510 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
1512 * dynl.c: The dynamic linking and module registration functions
1513 are now defined even when dynamic linking is not available for the
1514 host system. Some of their functionality can be done without
1515 dynamic linking; when it's really needed, they throw errors.
1517 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
1519 * configure.in: Only define DYNAMIC_LINKING when one of the system
1520 dependent functions is detected.
1521 * dynl.c (scm_dynamic_func): New function to get the address of a
1522 function in a dynamic object.
1523 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
1524 produced by scm_dynamic_func as the thing to call.
1526 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
1528 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
1529 (scm_register_module_xxx, scm_registered_modules,
1530 scm_clear_registered_modules): New functions.
1532 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
1534 * symbols.c (scm_sysintern): Renamed to
1535 scm_sysintern_no_module_lookup.
1536 (scm_sysintern): New function to take the place of the old
1537 scm_sysintern. It uses the current toplevel lookup closure to give
1538 the symbol its value. This is a temporary hack to put packages
1539 like gtcltk into their own module.
1540 (scm_can_use_top_level_lookup_closure_var): New variable to tell
1541 us whether `scm_top_level_lookup_closure_var' has been initialized
1543 * eval.c (scm_init_eval): Set it.
1545 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
1547 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
1548 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
1550 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
1552 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
1553 scm_sys_dup): deleted: FD capability will be added to other
1555 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
1556 scm_fd_free, fd_smob, scm_intern_fd.
1557 (scm_open): renamed from scm_sys_open. Return a port instead of
1558 an FD object. Make the mode argument optional.
1559 (scm_sys_create): deleted, it's just a special case of open.
1560 (scm_init_filesys): move interning of constants O_CREAT etc.,
1561 here (were previously using SCM_CONST_LONG macro).
1562 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
1564 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
1565 include "fports.h" and <stdio.h>
1566 (scm_stat, scm_select): don't support FD objects.
1568 * error.h: adjust scm_syserror_msg prototype.
1569 * error.c (scm_syserror_msg): take an extra argument for errno.
1570 Using the global value didn't always work, since it could be
1571 reset by procedure calls in the message or args arguments.
1573 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
1574 I don't understand why the check was there (and what about the
1577 * strop.c (scm_string_copy): allow shared substrings to be copied.
1579 * unif.h: corresponding change to prototypes.
1580 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
1581 recognize two new optional arguments: offset and length. Allow
1582 the port argument to be an integer (file descriptor, for scsh).
1583 Include <unistd.h> for "read" prototype.
1585 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
1587 * socket.c: don't include filesys.h.
1589 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
1591 * Makefile.am: add AWK=@AWK@ (?)
1593 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
1595 Add a rule to generate errnos.c from errnos.
1596 * error.c (scm_init_error): include errnos.c.
1597 * errnos_cnvt.awk: new file, converts the list of errno codes to
1599 * errnos_get.c: new file.
1600 * errnos.default: new file, contains errnos to try if they can't
1601 be extracted from errno.h.
1602 * configure.in: if using GCC, try and extract errno codes from
1606 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
1608 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
1609 * Makefile.am: Made libguile into a libtool library.
1610 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
1611 Set libtool_libs to indicate that libguile is a libtool library.
1612 See guile/ChangeLog for details.
1613 * .cvsignore: ignore "*.lo", the libtool library objects.
1615 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
1617 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
1618 use htons in getservbyport argument.
1620 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
1622 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
1623 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
1626 * objprop.c (scm_object_property): No need to take the CDR of the
1627 value returned by scm_object_properties, since Aug 20 change.
1629 * configure.in: When checking for struct linger, #include
1630 <sys/types.h> as well as <sys/socket.h>. I've never known
1631 <sys/types.h> to cause any portability problems, and Solaris's
1632 <sys/socket.h> needs it.
1633 * configure: Rebuilt.
1635 I think the Sun compiler has chosen a perverse way to interpret
1636 ANSI declarations combined with K&R definitions. We'll
1637 appease it a little bit. But when it invades France, we fight.
1638 * print.c (scm_iprlist): Change 'tlr' argument to an int.
1639 * print.h (scm_iprlist): Here too.
1640 * numbers.c (scm_divbigdig): Change definition to match
1641 declaration in numbers.h.
1642 * unif.c (scm_makflo): Change definition to match declaration in
1645 * init.c (scm_boot_guile): Don't return the value of
1646 scm_boot_guile_1. This function doesn't return a value;
1647 scm_boot_guile_1 doesn't return a value (or return at all).
1649 * eval.c (unmemocopy): Add a semicolon to appease the Sun
1652 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
1653 compile. I have a feeling this function is a bad idea anyway ---
1654 one should always test for features, not systems.
1656 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
1657 semicolons. Only pure luck kept this from being noticed earlier.
1659 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
1661 * socket.c (scm_recvfrom): Added missing semicolon.
1663 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1665 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
1666 the buffer and start and end positions for scsh networking
1669 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
1671 * configure.in: Revert previous change to this file; the problem
1672 is due to transient automake weirdness.
1673 * configure: Rebuilt.
1675 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
1676 PLUGIN/guile.libs. configure generates the latter from the former.
1677 * Makefile.in: Rebuilt.
1679 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
1680 need this if we install scripts, like guile-snarf.
1681 * configure: Rebuilt.
1683 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
1685 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
1687 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
1689 * socket.c (scm_addr_vector): fix faulty scm_listify.
1691 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
1693 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
1694 style block comment is no longer considered an error.
1696 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
1698 * PLUGIN/guile.libs.in: New file.
1699 * PLUGIN/guile.libs: Removed from repository.
1700 * configure.in: Create PLUGIN/guile.libs from
1701 PLUGIN/guile.libs.in. This is for including additonal libraries
1702 needed for dynamic linking.
1703 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
1704 instead of PLUGIN/guile.libs.
1706 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
1708 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
1710 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
1711 occurrences of the given element from the list, not just the
1712 first. This is how the Emacs Lisp functions behave, how the
1713 analogous Common Lisp functions behave, and (I believe) how the
1714 older Maclisp functions worked. I realize that this change may
1715 break code, but it seemed better to break it before the Guile
1718 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
1719 Their prototypes were already present in gc.h, but they weren't
1721 (scm_init_storage): Initialize scm_protects.
1722 * root.c (scm_protects): New element of scm_sys_protects.
1724 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
1726 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
1728 * libguile.h: Added #include "libguile/net_db.h".
1730 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
1731 30 change. That file is only meant for communication between the
1732 configuration process and load.c. If code linked against libguile
1733 wants to get at the paths mentioned in libpath.h, it can call
1734 functions declared in load.h.
1736 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1738 * libguile.h: Removed #include "libguile/fdsocket.h"
1740 * net_db.c: Added #include <sys/socket.h>.
1742 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
1744 * filesys.c (scm_input_waiting_p): use select in preference to
1745 FIONREAD, since the latter doesn't detect EOF.
1746 Throw error if neither select nor FIONREAD available.
1748 * socket.c (scm_connect): take a port, not a fd object.
1749 (scm_fill_sockaddr): throw an error if fam is not recognised.
1750 (scm_bind): use scm_fill_sockaddr.
1751 (scm_listen): take a port, not a fd object.
1752 (scm_accept): take and return a port. return #f in the car if
1753 address can't be got
1754 (scm_sock_fd_to_port): new procedure.
1755 (scm_socket): use scm_sock_fd_to_port.
1756 (scm_addr_vector): throw error if unrecognised address type.
1757 take an extra argument with the calling procedure name.
1758 (scm_getsockname): take a port. return #f if address can't be got.
1759 (scm_getpeername): take a port. return #f if address can't be got.
1760 (scm_recvfrom): take a port. return #f for address component if can't
1762 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
1763 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
1765 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
1767 * throw.c (scm_internal_catch): Make body funcs and handler funcs
1768 use separate data pointers, to allow them to be designed
1769 independently and reused.
1770 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
1771 Renamed from catch_body, catch_handler, and uncaught_throw; made
1773 (struct scm_catch_body_data): Renamed from catch_body_data; moved
1775 (scm_catch): Use the above.
1776 (scm_throw): Don't bother printing a message for an uncaught
1777 throw; we establish a default handler in init.
1778 * throw.h (scm_internal_catch): Prototype updated.
1779 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
1781 (struct scm_body_thunk_data): New structure, used as data
1782 argument to scm_body_thunk.
1783 * init.c (struct main_func_closure): New structure, packaging up
1784 the data to pass to the user's main function.
1785 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
1786 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
1787 scm_internal_catch to establish a catch-all handler, using
1788 scm_handle_by_message. This replaces the special-case code in
1790 (invoke_main_func): Body function for scm_internal_catch; invoke
1791 the user's main function, using the main_func_closure pointer to
1792 decide what to pass it.
1793 * root.c (struct cwdr_body_data): Remove handler_proc member.
1794 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
1795 (cwdr_handler): Removed.
1797 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1799 * socket.h (SCM_P): update bind prototype.
1800 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
1801 include "feature.h".
1802 (scm_socket): return a port, not a file descriptor object.
1803 include "fports.h" and <unistd.h>
1804 (scm_bind): take a port, not a file descriptor object.
1805 take an extra argument for address args.
1807 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
1808 INADDR_NONE, INADDR_LOOPBACK.
1810 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
1812 * init.c: include net_db.h and not fdsocket.h.
1813 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
1815 * Makefile.am: corresponding changes.
1816 * socket.h: renamed from fdsocket.h, fix names.
1817 * net_db.h: renamed from socket.h, fix names.
1818 * socket.c: renamed from fdsocket.c.
1819 remove _sys from procedure names.
1820 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
1821 add "socket" to features list.
1822 * net_db.c: renamed from socket.c.
1823 remove _sys from procedure names.
1824 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
1825 add "net-db" to features list.
1826 include "net_db.h". don't include <sys/socket.h> or
1829 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1831 * tags.h (scm_tags): Removed comma at end of last enumerator.
1833 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
1835 Don't use GCC extensions to allocate space for debugging frames.
1836 (Here he goes again! Why do we put up with this?!)
1837 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
1838 an scm_debug_info structure, not an in-line array of them. Add
1839 'info' member, to say how many vect elements we've used, for eval
1841 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
1842 a new variable debug_info_end to mark the end of vect, instead of
1843 the address of the 'info' pointer itself.
1844 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
1845 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
1846 (SCM_APPLY): Explicitly allocate space for debug.vect.
1847 * debug.c (scm_m_start_stack): Same, for vframe.vect.
1848 * stacks.c: Adjusted for new debug frame structure.
1849 (RELOC_INFO, RELOC_FRAME): New macros.
1850 (stack_depth, read_frames): Use them, and new scm_debug_frame
1851 element 'info', instead of magically knowing that eval frames have
1852 an info pointer sitting after vect.
1853 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
1855 (scm_init_stacks): Formatting tweaks.
1857 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
1859 Give GCC more control flow information, so it can be sure that
1860 variables aren't used uninitialized.
1861 * error.h (scm_error, scm_syserror, scm_syserror_msg,
1862 scm_sysmissing, scm_num_overflow, scm_out_of_range,
1863 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
1864 scm_misc_error): Tell GCC that these functions never return.
1865 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
1866 out the field type, call abort if SCM_ASSERT returns, to placate
1868 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
1869 scm_wta ever returns. We can't handle this case anyway, and this
1870 gives the optimizer more information.
1871 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
1872 scm_wta ever returns.
1874 In some cases, the code is fine, but GCC isn't smart enough to
1875 figure that out; this usually happens when one variable is only
1876 initialized and used when a particular condition holds true, and
1877 we know that condition will never change within a given invocation
1878 of the function. In this case, we simply initialize the variables
1879 to placate the compiler, hopefully to a value which will cause a
1880 crash if it is ever actually used.
1881 * print.c (scm_iprin1): Initialize mw_pos.
1882 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
1883 * throw.c (scm_ithrow): Initialize dynpair.
1884 * unif.c (scm_uniform_vector_ref): Initialize cra.
1885 * struct.c (init_struct): Initialize prot.
1886 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
1888 * strports.c (scm_eval_0str): Don't return uninitialized garbage
1889 if EXPR contains no expressions.
1891 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
1893 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
1894 cause an infinite loop (???). So much for the algebraic
1895 equivalency of variable-sized arrays and alloca...
1897 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
1899 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
1900 a SCM boolean, not a C boolean.
1902 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
1904 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
1905 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
1906 rules for raising scm_mtrigger. Previously, unfortunate but not
1907 unlikely circumstances could result in almost constant invokation
1908 of the gc. Now, this situations should be less likely, but they
1909 are not prevented completely.
1911 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
1913 * numbers.c (scm_fuck): Procedure removed; looks like old test
1915 * numbers.h: Prototype removed.
1917 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
1919 * debug.h (scm_debug_frame): Change `vect' member from an in-line
1920 array to a pointer, to match my Nov 21 change in eval.c.
1922 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1924 * libguile.h: Added #include "libguile/backtrace.h", #include
1925 "libguile/stacks.h".
1927 * strings.c (scm_string scm_make_string scm_string_ref
1928 scm_string_set_x scm_string_equal_p scm_string_append):
1929 Bugfix according to scm patch from Aubrey Jaffer:
1930 Corrected long-standing
1931 (not (eqv? (integer->char 128)
1932 (string-ref (make-string 1 (integer->char 128)) 0)))
1933 bug found by John Kozak <jk@noontide.demon.co.uk>.
1935 * strports.c, strports.h: Make scm_eval_0str return the value of
1936 the last expression evaluated (previously, it returned void).
1938 * strports.c, strports.h: New function: scm_read_0str. Does what
1941 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
1943 * simpos.c (scm_getenv): return #f if string can't be found in the
1944 environment instead of throwing an exception, for compatibility
1945 with numerous other systems.
1947 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
1949 * Makefile.am (.c.x): Use guile-snarf.
1950 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
1952 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
1954 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1956 * backtrace.c (scm_display_error_message): Made non-static, and
1957 renamed from display_error_message.
1958 * backtrace.h (scm_display_error_message): Added extern decl.
1959 * throw.c (uncaught_throw): Use it to display the error message.
1961 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
1963 * inet_aton.c: Use #if 0, not #ifdef 0.
1965 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
1967 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
1968 to convert the returned value.
1969 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
1970 the offset argument.
1972 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
1974 Add new interface to catch/throw, usable from C as well as
1976 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
1977 (scm_internal_catch): New function, replaces...
1978 (scm_catch_apply): Deleted.
1979 * throw.c (scm_catch_apply): Deleted; replaced with a more general
1980 mechanism which is a bit more code, but can be used nicely from C
1981 and implement the Scheme semantics as well.
1982 (scm_internal_catch): This is the replacement; it's named after
1983 the analogous function in Emacs.
1984 (scm_catch): Reimplemented in terms of the above.
1985 (struct catch_body_data, catch_body, catch_handler): New
1986 functions, used by scm_catch.
1987 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
1988 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
1989 support for new cwdr.
1991 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
1994 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
1996 * acconfig.h: Added DYNAMIC_LINKING symbol.
1997 * configure.in: Add option and checks for dynamic linking.
1998 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
1999 dynl.h: New files for dynamic linking support.
2000 * Makefile.am (libguile_a_SOURCES):
2002 (modinclude_HEADERS): Added "dynl.h".
2003 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
2005 * init.c (scm_boot_guile_1): Call
2006 scm_init_dynamic_linking to initialize dynamic linking support.
2008 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
2010 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
2011 (as we Schemers say). It needs to be global, so that I can tweak
2012 it for the proper operation of unexec.
2013 (scm_boot_guile_1_live): New variable, see above.
2015 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
2017 * guile-snarf.sh: Removed.
2018 * PLUGIN/guile.libs: Added dependency for -lm.
2019 * acinclude.m4: Renamed from aclocal.m4.
2020 * PLUGIN/greet: Removed.
2021 * Makefile.am, aclocal.m4: New files.
2022 * configure.in: Updated for Automake.
2024 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
2026 * eval.c (scm_definedp): Use top_level_lookup_closure_var
2027 and not top_level_lookup_thunk_var.
2029 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
2031 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
2033 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
2035 * eval.c (scm_definedp): Incompatibly changed to be a builtin
2036 Scheme function, instead of syntax. Single argument is now a
2039 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2041 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
2042 scm_ra_divide): Properly terminate statements passed as arguments
2043 to IVDEP macros. (Thanks to Bernard Urban.)
2045 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
2046 with non-constant sizes. (Thanks to Bernard Urban.)
2048 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
2050 It's an "eval closure", not an "eval thunk." A thunk is a
2051 function of no arguments.
2052 * root.h (struct scm_root_state): Renamed
2053 top_level_lookup_closure_var from top_level_lookup_thunk_var.
2054 (scm_top_level_lookup_closure_var): Renamed from
2055 scm_top_level_lookup_thunk_var.
2056 * root.c (mark_root): Uses changed.
2057 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
2058 * init.c (scm_start_stack): Uses changed.
2059 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
2060 Change scheme-visible name to *top-level-lookup-closure* from
2061 *top-level-lookup-thunk*.
2063 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
2065 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
2066 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
2068 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
2070 * gc.c (struct scm_heap_seg_data): Doc fixes.
2072 * gc.c (scm_gc_sweep): Empty all segments' freelists before
2073 sweeping. Then, prepend each segment's free cells to its
2074 freelist, rather than wiping out the old value. (Thanks to Marius
2077 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
2078 scm_check_freelist, scm_debug_newcell): New functions and
2079 variables, for debugging freelist problems.
2080 * pairs.h (SCM_NEWCELL): New debugging version added.
2081 * gc.h (scm_debug_newcell): Added extern declaration, used by
2082 debugging version of SCM_NEWCELL.
2084 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
2086 On some systems <libc.h> conflicts with <unistd.h>, and should not
2087 be #included at all.
2088 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
2089 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
2090 * configure.in: Call it.
2091 * posix.c, filesys.c: Use its results to decide whether or not to
2093 * configure, scmconfig.h.in: Rebuilt with autoconf and
2096 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2098 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
2099 pointer to the stdio stream before calling scm_setbuf0, so the
2100 latter will be able to retrieve it. I'm surprised this didn't
2101 segfault earlier. (Thanks to Christopher Lee.)
2103 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2105 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
2108 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2110 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
2111 number of stack narrowing specifier pairs. The first specifier in
2112 a pair controls inner border, the second the outer border. A
2113 number means cut that number of frames, a procedure object means
2114 cut until that object is found in operator position in a frame.
2116 * root.c (cwdr): Bugfix.
2118 * read.c: Recording of positions disabled by default.
2120 * procs.c (scm_closure_p): New function.
2122 * posix.c (scm_tmpnam): New function.
2124 * load.c: Added #include "throw.h".
2125 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
2128 * load.c, load.h (scm_read_and_eval_x): New function.
2130 * eval.c: Renamed debug option "deval" to "debug".
2132 (scm_eval_x): `eval!' is no longer accessible from the scheme
2133 level. Motivation: We can't allow operations which introduce
2134 glocs into the scheme level. Guile's type system can't handle
2135 these as data. Use `eval' or `read-and-eval!' as replacement.
2137 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
2138 SCM_CONSP since this is a macro!; Set vframe.prev to
2139 scm_last_debug_frame instead of 0. In this way we can look
2140 "above" the virtual start stack frame if we wish.
2141 (scm_debug_hang): New function: Useful for debugging Guile in
2142 certain tricky situations. Will probably be removed later...
2144 * debug.h: Changed semantics of debug option "backtrace". This
2145 option now only indicates whether we want automatic backtrace at
2148 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2150 * ports.c: #include "filesys.h"
2151 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
2153 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
2154 Motivation: This is system specific code which is related to file
2155 I/O. It also may use select. Added code by Gary Houston to
2156 detect presence of character in stdio buffers.
2158 * libguile.h: #include "libguile/libpath.h"
2160 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
2161 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
2162 SCM_SITE_DIR; Install libpath.h among the other include files.
2164 * load.c, load.h (scm_sys_package_data_dir): New function.
2166 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2168 * stacks.h: Bugfix: Don't use tail-array length field as stack
2169 length field! This screwed GC.
2171 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2173 * _scm.h: Added #ifndef around definition of macros min and max.
2175 * __scm.h: Added hooks for threads to plugin to in ints protection
2176 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
2177 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
2178 the main code in these macros duplicated and spread over multiple
2179 files. Renamed SCM_THREADS_SWITCHING_CODE ->
2180 SCM_THREAD_SWITCHING_CODE.
2182 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
2184 * snarf.h: New file.
2185 * guile-snarf.sh: New file.
2186 * Makefile.in (inner_h_files): Added snarf.h
2187 (ancillary, install, uninstall, distclean): Added actions for
2189 (.c.x): Use guile-snarf.
2190 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
2191 (gen_c_files): Note that these depend on guile-snarf.
2192 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
2193 now in "snarf.h". Added #include "snarf.h" to get them.
2194 * libguile.h: Added #include "snarf.h".
2195 (Patches applied and tweaked by Jim Blandy.)
2197 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2199 * socket.c: Use K&R style declaration for 'close'; the GNU coding
2200 standards suggest against providing prototypes for system
2201 functions. Thanks to Greg Troxel.
2203 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
2205 * strports.c (scm_eval_0str): New function.
2206 #include "read.h", to get prototype for scm_read.
2207 * Makefile.in (strports.o): Update dependencies.
2208 * strports.h: New prototype.
2210 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
2211 scheme name from "int?" to "integer?". It seems to do the job.
2212 * numbers.h: Rename prototype too.
2213 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
2216 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
2217 scm_num_eq_p): Rename these according to R4RS conventions: call
2218 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
2219 to making libguile R4RS compliant without ice-9...
2221 * load.c (scm_sys_search_load_path): Search for files under all
2222 extensions listed in the %load-extensions variable. If FILENAME
2223 is absolute, return it unchanged, without searching the load path.
2224 (scm_loc_load_extensions): New variable, pointing to
2225 %load-extensions' value cell.
2226 (scm_init_load): Initialize it, and the value it points to.
2227 (scm_primitive_load_path): Improve error reporting.
2229 * load.c (scm_loc_load_hook): New variable, pointing to value cell
2230 of new Scheme variable %load-hook.
2231 (scm_primitive_load): Apply %load-hook to filename.
2233 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
2235 * configure.in: add tests for figuring out whether buffered data
2236 is available in a FILE structure, which is needed by char-ready.
2238 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
2241 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
2242 exceptions using misc_error instead of syserror. It seems a bit
2243 odd to throw an exception if a string can't be found in the
2244 environment, but it's consistent with open-file, stat etc.
2245 (simpos.h): remove sys_ from getenv.
2247 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
2248 occurs, throw an error instead of returning errno. Return value
2250 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
2252 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
2254 * filesys.c (scm_stat2scm): derive file type and permissions from
2255 the stat mode and append them to the returned vector.
2256 There isn't much overhead in doing this and it avoids the need to
2257 work with S_IRUSR et al. in Scheme.
2258 Define symbols scm_sym_regular etc.
2259 (scm_init_filesys): don't intern S_IRUSR etc.
2261 * load.c: change s_try_load and s_try_load_path to s_primitive_load
2262 and s_primitive_load_path.
2264 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
2266 * error.h: don't declare error symbols. prototype for scm_misc_error.
2268 * stackchk.c (scm_stack_overflow_key): defined here instead of in
2271 * error.c: use SCM_SYMBOL to set up error keys.
2272 scm_misc_error: new procedure.
2274 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
2276 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
2277 between `#!' and `!#' is ignored.
2278 (skip_scsh_block_comment): New function.
2280 * feature.c (scm_set_program_arguments): New argument, FIRST.
2281 * feature.h: Update prototype.
2282 * init.c (scm_boot_guile_1): Pass new argument to
2283 scm_set_program_arguments.
2285 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
2287 * init.c (scm_start_stack): Don't initialize scm_progargs here.
2288 (scm_boot_guile): Call scm_set_program_arguments here, later than
2289 the old initialization.
2291 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
2292 initialization procedure.
2293 - Delete in, out, err arguments; there are other perfectly good
2294 ways to override these when desired.
2295 - Delete result argument; this function shouldn't ever return.
2296 - Rename init_func argument to main_func, for less confusion.
2297 - Delete boot_cmd argument; main_func is more general.
2298 -Add 'closure' argument, to help people pass data to main_func
2299 without resorting to global variables.
2300 - Abort if reentered; don't bother returning an error code.
2301 - Call scm_init_standard_ports to set up the default/current
2302 standard ports; no need to pass them to scm_start_stack.
2303 - Remove code to evaluate the boot_cmd, and start the repl; let
2304 the user do something like that in main_func if they want.
2305 - Remove code to package up a return value; main_func can do any
2307 - Call exit (0), instead of returning.
2308 (scm_start_stack): Don't initialize the I/O ports here; that's
2309 weird. Delete in, out, err arguments. Move guts to
2310 scm_init_standard_ports, scm_stdio_to_port.
2311 (scm_init_standard_ports): New function, to set up current and
2312 default standard ports.
2313 (scm_start_stack, scm_restart_stack): Make these static.
2314 * init.h (scm_boot_guile): Adjust declaration.
2315 (scm_start_stack, scm_restart_stack): Remove externally
2316 visible declarations for these.
2317 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
2319 * fports.c (scm_stdio_to_port): New function. Its guts used to be
2320 written out several times in scm_start_stack.
2321 * fports.h: New declaration for the above.
2323 * feature.c (scm_set_program_arguments): New function.
2324 * feature.h: New declaration for the above.
2326 * ports.c: Formatting tweak.
2328 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
2330 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
2331 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
2332 for obtaining the address of a car or cdr field. Motivation:
2333 &SCM_CXR make assumptions about the internal structure of the
2336 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
2337 Motivation: see SCM_CXRLOC.
2339 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
2340 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
2341 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
2342 Motivation: Safer use. Some other macros are defined in terms of
2343 these operations. If these are defined using the SCM_SETCXR
2344 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
2345 to inefficiency and an <e1> with side-effects could potentially
2346 break. Also, these particular operations are heavily utilized in
2347 the garbage collector. In unoptimized code there will be a
2350 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
2351 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
2352 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
2353 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
2354 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
2355 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
2356 vports.c: Cleaned up use of pairs: Don't make any special
2357 assumptions about the internal structure of selectors and
2358 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
2359 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
2360 (Among other things, this change makes it easier to build Guile
2361 with certain compilers which have problems with casted lvalues.)
2363 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2365 * stacks.c: Improve selection of relevant stack frames when making
2366 a stack object. Introduce one level of indirection in the stack
2367 object to make it possible to "narrow" to a certain region of the
2368 stack. This facilitates making use of more clever algorithms (not
2369 implemented) for selecting relevant frames and gives a cleaner
2370 design since selection of frames can be done independently of
2371 extraction of frames from the real stack.
2372 (scm_stack_id): Also take #t as argument which means look at
2375 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
2376 Turn n_tail into an integer directly representing current number
2377 of frames in stack. Add field tail.
2379 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
2381 * debug.c (scm_make_memoized): Made it available at scheme level.
2382 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
2383 SCM_NIMP before applying heavier predicates in argument checking.
2384 (scm_local_eval): Also take memoized object as argument.
2386 * backtrace.c (scm_display_error): Just a safety measure: Stacks
2387 aren't created with zero length, but should such a strange
2388 creature suddenly turn up...
2390 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
2392 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
2393 `del', for the sake of C++ compilers. (Patch applied by JimB.)
2395 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
2397 * variable.c (scm_make_variable): Make the name hint optional, as
2399 (anonymous_variable_sym): Renamed from variable_sym. All uses
2402 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
2403 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
2404 of scm_primitive_load_path was also changed to
2405 "primitive-load-path", from "%try-load-path". Callers changed.
2406 We'd like to respect the convention that a function named
2407 "try-mumble" should behave just like the function called "mumble",
2408 but return #f instead of signalling some error.
2409 * load.h: Rename prototypes.
2411 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2413 * print.c (make_print_state, grow_print_state), print.h: Modified
2414 the print state representation: Don't use a tail array for
2415 recording of circular references. Resizing of the print state
2416 structure invalidates the print state pointer. To avoid passing
2417 around an indirect print state reference to all printing
2418 functions, we instead let the print state reference a resizable
2421 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
2423 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
2424 Don't crash when passed an improper list terminated by a
2425 non-immediate value.
2427 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
2429 Allocate data for structures on an eight-byte boundary, as
2430 required by the tagging system.
2431 * struct.c (alloc_struct): New function.
2432 (scm_make_struct, scm_make_vtable_vtable): Call it.
2433 * struct.h (scm_struct_n_extra_words): Bump to 3.
2434 (scm_struct_i_ptr): New "field".
2435 * gc.c (scm_gc_sweep): When we need to free the data, use the
2436 information stored by alloc_struct to find the beginning of the
2437 block allocated to the structure, so we can free it.
2439 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2441 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
2444 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
2445 (scm_debug_info): New member: id.
2447 * stacks.c: Stacks are now represented as structs; Stacks have an
2448 id given to them by `start-stack'.
2449 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
2451 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
2452 Changed stack representation.
2454 * debug.c (scm_procedure_name): Try procedure property `name' for
2455 compiled closures aswell.
2457 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
2459 * eval.c: scm_i_name moved to gsubr.c
2460 (scm_m_define): Record names of all kinds of procedure
2461 objects. (Earlier, only closures were recorded.)
2463 * procprop.h: Added declaration of scm_i_name.
2465 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
2466 (scm_make_gsubr): Record names of compiled closures.
2468 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2470 * debug.c, debug.h: Removed obsolete code.
2472 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
2473 stacks.c: Renamed regs --> scm_contregs.
2475 * print.c (scm_free_print_state): Cleanup print state before
2476 returning it to pool. It is better to do it here than in
2477 scm_prin1 since scm_prin1 is called often.
2479 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
2480 s_set_source_property_x): Check that first argument is a pair or a
2483 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
2484 scm_i_line, scm_i_column and scm_i_breakpoint global.
2486 * init.c: Added #include "backtrace.h" and #include "stacks.h".
2487 (scm_boot_guile_1): Added calls to scm_init_backtrace and
2490 * debug.h: Added debug object smob declaration and macro
2493 * configure.in: Build with backtrace.o and stacks.o if debug
2496 * Makefile.in: Added entries for new files: backtrace.c,
2497 backtrace.h, stacks.c and stacks.h.
2499 * symbols.c (scm_sym2ovcell): Fixed documentation.
2501 * _scm.h (min, max): Added.
2503 * async.c: Moved `min' macro to _scm.h.
2505 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
2506 SCM_BACKTRACE_INDENT.
2508 * eval.c: Added new debug options `maxdepth' and `indent'.
2510 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
2512 * print.h: Added selector SCM_PRINT_STATE.
2514 * print.c: New functions: scm_make_print_state,
2515 scm_free_print_state.
2517 * print.h: Added declarations for scm_make_print_state,
2518 scm_free_print_state.
2520 * debug.c (scm_m_start_stack): New acro.
2522 * debug.h: Small cleanup.
2524 * init.c (scm_boot_guile_1): Moved scm_init_debug below

2547 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
2548 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
2549 declare functions with prototypes. (Patch thanks to Marius
2552 More prototype-related changes from Marius Vollmer:
2553 * gdb_interface.h: Wrapped header file in #ifdef/#endif
2554 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
2555 * ports.h (ptobfuns): Added prototypes. This means some casting in
2557 * fports.c: Added casts for initializations, since the functions
2558 are defined to take FILE * as their stream argument, not SCM.
2559 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
2560 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
2561 to `char *str_data' to conform to prototype.
2563 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2565 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
2567 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
2569 * stime.c, stime.h: use SCM_P method.
2571 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2573 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
2574 be given at least two arguments. Insist that lst's last element
2575 be a list, but don't make any requirements of its predecessors.
2577 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
2579 * eval.c (scm_nconc2last): Revert last change; there seems to be
2580 other stuff going on here.
2582 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
2584 * eval.c (scm_nconc2last): Make sure that each element of lst
2585 (which is a list of argument lists, except for the tail) is a
2586 proper list, i.e., finite and terminated by '().
2588 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
2590 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
2593 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
2594 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
2597 * vectors.c (scm_make_vector): Fill vectors with the undefined
2598 value, to help make Guile Scheme code more portable to other
2601 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
2602 * symbols.h, tags.h: Doc fixes.
2604 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
2606 * async.c (scm_take_signal): Doc fixes.
2608 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
2610 * numbers.c (scm_divbigint): When the remainder is zero, we don't
2611 want to subtract it from the modulus; we just want to leave it
2614 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
2616 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
2619 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
2621 * throw.c (scm_catch_apply): Finished implementation of
2624 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
2626 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
2628 (scm_init_filesys): set "i/o-extensions" feature.
2631 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
2633 * Makefile.in (root.o): Correct dependencies.
2635 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
2637 * Makefile.in: Added dependency entry for root.o.
2639 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
2640 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
2642 * init.c (scm_start_stack): Set initial root continuation number
2645 * procs.c: New function: scm_thunk_p.
2647 * procs.h: Added declarations of scm_thunk_p.
2649 * root.c: Renamed `call-with-new-root' -->
2650 `call-with-dynamic-root'.
2651 (cwdr): Removed allocation of new root state. This should be done
2652 separately by use of scm_make_root.
2653 (scm_apply_with_dynamic_root): New function: Does what it
2654 sounds like. Needed when spawning threads.
2656 * root.h: Added member last_debug_frame to root state.
2657 Added #include "libguile/debug.h"
2659 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
2660 arguments. The motivation is that code in root.c needs catch
2661 functionality, and we want to avoid code duplication.
2662 New functions: scm_catch, scm_lazy_catch. These are wrappers for
2663 scm_catch_apply. scm_lazy_catch is intended to introduce catch
2664 handlers that run without popping the stack into the dynwind
2667 * throw.h: Added prototypes for scm_catch_apply and
2670 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2672 * root.h (scm_root, scm_set_root): Decouple thread support details
2673 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
2674 SCM_SET_THREAD_LOCAL_DATA.
2676 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
2677 and tortoise scanning loop.
2679 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
2681 * Makefile.in: Rebuild dependencies.
2683 * libguile.h: #include "libguile/print.h" before "smob.h", since
2684 the latter uses the print_state structure.
2686 * throw.c (scm_ithrow): Use the correct variable when checking to
2687 see if a given element of scm_dynwinds is a valid catch.
2689 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
2690 structure, abort; don't just silently ignore the garbage.
2692 * _scm.h: #include "print.h" here, since it seems to be used just
2694 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
2695 strports.c, unif.h: Don't #include "print.h".
2697 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2699 * feature.h (scm_loc_features): Removed external declaration.
2700 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
2702 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
2704 * feature.c (scm_init_feature): Added threads feature (needs to be
2705 initialized here, since features doesn't exist when
2706 scm_init_threads is called).
2708 * libguile.h: Added #include "libguile/../threads/threads.h".
2709 (This is a kludge to get thread support working. This should be
2712 * configure.in, acconfig.h: Added flags for thread support.
2714 * scmsigs.c: Define `signal' to be `pthread_signal' if using
2717 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
2718 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
2721 * _scm.h: Added conditional #include "threads.h"
2723 * __scm.h (SCM_ASYNC_TICK): Added call to macro
2724 SCM_THREADS_SWITCHING_CODE.
2726 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
2727 allocate the basic dynamic root object.
2728 (scm_boot_guile): Added call to scm_init_root.
2730 * root.c, root.h: Added root smob.
2731 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
2732 functions: Implements dynamic roots mostly according to spec in
2733 SCM manual. Main difference is that the second argument is a
2734 throw handler rather than an error "thunk".
2736 * root.h: Added declaration of scm_init_root.
2738 * root.c: Added #include "genio.h", #include "smob.h", #include
2739 "pairs.h", #include "throw.h", #include "dynwind.h", #include
2741 (scm_init_root): Added #include "root.x".
2743 * throw.c: Added #include "stackchk.h"
2744 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
2745 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
2746 can be used in scm_call_with_new_root; Added reenabling of stack
2747 checking when catching a throw.
2749 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
2751 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
2753 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
2754 element is not found, as per R4RS.
2756 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2758 * list.c: Doc fixes throughout.
2760 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
2762 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
2763 declare the char * to be const. Avoids a warning in rgx.c.
2765 * ports.h: spelling fix.
2767 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
2770 * load.c (scm_sys_try_load_path): throw an error if file not found
2771 (like it says it in NEWS).
2773 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
2775 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
2776 PROPS slot to '(), not #f; it's an empty alist.
2778 * throw.h, throw.c: Use SCM_P instead of #if hair.
2780 Remove special support for uncaught throws; see throw.c for
2782 * throw.c (uncaught_throw): New function.
2783 (scm_ithrow): Call uncaught_throw if we don't find a throw
2784 target; don't mess with scm_bad_throw_vcell.
2785 (scm_bad_throw_vcell): Variable deleted.
2786 (scm_init_throw): Don't initialize it.
2788 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
2791 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
2793 * numbers.c (scm_istr2int): If the number is short (as most
2794 numbers are), just call scm_small_istr2int to deal with it.
2795 (scm_small_istr2int): New function, created by un-#ifdefing the
2796 non-bignum version of scm_istr2int and renaming it.
2798 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
2800 * load.c (scm_sys_try_load): don't check whether value returned
2801 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
2802 Change the Scheme name from %try-load to primitive-load.
2804 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
2805 Can avoid passing a message, allowing it to be derived in the
2806 error handler (e.g., if we want to throw to the key both from
2809 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
2811 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
2812 references now have a new appearance which is more compact and
2813 also gives a clue about what the target of the reference is.
2814 By setting parameters in the print state, more fancy printing can
2815 be achieved. This is used by the (not yet commited) backtrace
2818 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
2820 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
2823 * print.c: Added #include "struct.h". Removed function
2826 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
2827 scm_iprin1. Removed prototype for scm_prlist.
2829 * arbiters.c (prinarb),
2830 async.c (print_async),
2831 debug.c (prindebugobj, prinmemoized),
2832 eval.c (prinprom, prinmacro),
2833 filesys.c (scm_fd_print, scm_dir_print),
2835 mallocs.c (prinmalloc),
2836 numbers.c, numbers.h (scm_floprint, scm_bigprint),
2837 smob.h (scm_smobfuns),
2838 srcprop.c (prinsrcprops),
2840 unif.c, unif.h (scm_raprin1, rapr1),
2841 variable.c (prin_var): Changed argument `int writing' to
2842 `scm_print_state *pstate'.
2844 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
2845 that it will be called before scm_init_print.
2847 * print.c (scm_prin1): Print states are now allocated when calling
2848 scm_prin1 and then passed around to all printing functions as an
2849 argument. A cache `print_state_pool' enables reuse of print
2851 (scm_make_print_state): New function.
2852 (scm_iprin1): Adaption to print states.
2853 (scm_iprlist): An initial "hare and tortoise" scan brings down
2854 time complexity to O (depth * N). (Better time complexity will be
2855 achieved when the printing code is completely rewritten.)
2857 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
2859 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
2860 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
2861 it gets done whether or not the cache variable has a value.
2863 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
2865 Distinguish #f and ().
2866 * __scm.h: #undef SICP.
2867 * pairs.h (SCM_EOL): Delete this definition, equating it with
2869 * tags.h (SCM_EOL): Give it a new definition here; I think I found
2870 the value it used to have. Doc fixes, too.
2872 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
2874 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
2875 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
2876 Lord's implementation of structs, allowing for tail arrays as
2877 described in the manual. Also fixed some bugs. (Both the interface
2878 and the implementation should be improved.)
2880 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
2882 * print.c, print.h: Closures now print like #<procedure foo (x)>.
2883 People who whish to see the source can do `(print-enable 'source)'.
2884 Removed #ifdef DEBUG_EXTENSIONS.
2886 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2888 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
2889 integer (assuming for now accepting an integer is a good thing).
2891 * error.c, fports.c: replace use of %S in lgh_error args with %s.
2892 %S will be used instead for write'ing arguments.
2894 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
2895 asserts. fix a few other asserts.
2896 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
2897 scm_uniform_vector_ref, scm_array_set_x,
2898 scm_dimensions_to_unform_array): change args in
2899 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
2900 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
2901 scm_substring_fill_x): likewise.
2902 gsubr.c (scm_gsubr_apply): likewise.
2903 eval.c (SCM_APPLY): likewise.
2905 * eval.c (4 places): replace scm_everr with lgh_error or
2908 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
2909 scm_memory_error): new procedures.
2910 scm_everr: deleted. can use scm_wta, dropping first two args.
2911 scm_error: convert NULL subr to SCM_BOOL_F.
2913 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
2916 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
2919 * error.c, error.h: new error keys: scm_arg_type_key,
2920 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
2922 scm_wta: reimplement using lgh_error instead of scm_everr.
2924 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
2926 * gdbint.c: scm_lread now has one more argument.
2928 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
2929 scm_port_\1; Added mutator scm_set_port_filename_x (used when
2930 loading source from non-file ports, which, e. g., happens when
2931 using the Emacs interface).
2933 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
2936 * read.c: Added code for recording of positions of source code
2937 expressions; New functions: recsexpr, scm_lreadrecparen;
2938 _scm_make_srcprops --> scm_make_srcprops
2939 (scm_flush_ws): Removed updating of positions counters. This work
2940 is already done by scm_gen_getc
2942 * read.h: Added prototype for scm_lreadrecparen
2944 * print.c: Added #include "alist.h"
2946 * eval.c: Added #include "hash.h"

2954 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
2955 --> scm_make_srcprops
2957 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
2958 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
2959 function calls in the definition of the whash access macros.
2961 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
2963 * init.c (scm_boot_guile): Add level of indirection to
2964 scm_boot_guile_1() to ensure that stack base pointer is properly
2965 initialized. There was no guarantee that variable i was the
2966 highest/lowest variable on stack (i.e. the call frame of
2967 scm_boot_guile was not completely protected from gc).
2969 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
2971 * ports.h (scm_port_table): put back file_name, it will be used to
2972 support debugging. Undo related changes in fports.c, ioext.c,
2975 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
2977 * ports.h (scm_port_table): remove file_name member for now, it seems
2979 * fports.c (scm_open_file): don't set file_name in PTAB.
2980 (prinfport): don't use file_name in PTAB.
2981 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
2982 * ports.c (scm_add_to_port_table): don't intialize file_name.
2983 (scm_port_file_name): remove for now.
2984 * gc.c (scm_gc_mark): don't mark PTAB file_name.
2986 * fports.h (scm_mkfile): prototype deleted.
2987 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
2989 * debug.c, unif.c: use scm_out_of_range instead of
2990 wta for range errors (ASSERT still needs work).
2992 * error.c, error.h (scm_out_of_range): new procedure.
2994 * error.c, error.h (scm_out_of_range_key): new key.
2996 * posix.c (scm_sync): #else was missing.
2998 * error.c, error.h: append _key to names scm_num_overflow and
3001 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
3002 of consing an empty list.
3003 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
3004 of macros, saves code and string space.
3005 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
3006 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
3007 lower case. Rename scm_syserror_m to scm_syserror_msg.
3008 error.h: prototypes for new procedures.
3010 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
3012 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
3014 * error.c, error.h: setup scm_num_overflow key.
3016 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
3017 Remove definition of SCM_OVSCM_FLOW.
3019 * fports.c (scm_open_file): use SCM_SYSERROR_M.
3021 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
3022 explicit message and args.
3024 * error.c, error.h, __scm.h: change system_error_sym to
3027 * error.c (system_error_sym): remove leading %% from the Scheme name
3030 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
3032 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3034 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
3035 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
3036 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
3037 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
3038 renamed. (These were introduced by unsupervised name
3041 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3043 * print.c: Added code for detection of circular references during
3044 printing. (init_ref_stack, grow_ref_stack): New functions. Added
3045 a hook for printing of closures (accessible via print options).
3046 This leads to a split of calls to scm_iprin1 into two classes:
3047 elementary print operations (e. g. the code which prints a smob)
3048 still use scm_iprin1 while top level calls (like scm_display) use
3049 scm_prin1. scm_prin1 begins by clearing the data structure used
3050 to record reference information.
3052 * print.h: Added declarations of scm_prin1 and scm_prlist.
3054 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
3056 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
3058 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
3060 * error.c (err_head): scm_iprin1 --> scm_prin1
3062 * debug.c: Adjusted header comment.
3066 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
3068 * strerror.c: Doc fix.
3070 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3072 * gdbint.c (gdb_read): Now possible to run during GC.
3073 (unmark_port, remark_port): New functions.
3075 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
3077 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
3078 of allocating a new string object. Also, increase size by
3079 the factor 2 instead of 1.5.
3081 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
3083 * __scm.h (SCM_P): Corrected to run under traditional C.
3085 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
3088 * async.c: Calls to scm_sysintern corrected.
3090 * async.h (scm_async_clock): Redundant declaration removed.
3092 * continuations.c (scm_dynthrow): Redundant declaration removed.
3094 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
3095 Definition typos corrected.
3097 * debug.h: Missing declarations of functions in debug.c added
3100 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
3101 Missing declarations to functions in eval.c added.
3103 * filesys.c: Possibly uninitialized variable rv.
3105 * gc.h (scm_object_addr, scm_unhash_name): Missing
3106 declarations of functions defined in gc.c added.
3108 * genio.c: Possible typos str_data -> wstr_data. ???
3110 * genio.c: Possibly unintended shadowing of local variable
3111 `int c' (gotos out of scope of inner `c'). ???
3113 * init.c: Uninitialized `SCM last' may be used.
3115 * ioext.h: (scm_sys_isatty_p): Typo.
3117 * list.h (scm_list_head): Missing prototype for function in
3120 * numbers.c (scm_two_doubles): Changed from extern to static
3121 (is used only within numbers.c).
3123 * numbers.h: Repeated declarations removed.
3125 * ports.h (scm_close_all_ports_except): Declaration for the
3126 function defined in ports.c added.
3128 * posix.h: Missing declarations added.
3130 * procs.h (scm_make_subr_opt): Missing declaration added.
3132 * socket.h (scm_sys_gethost): Missing declaration added.
3134 * socket.h: Redundant declarations removed (they are in fdsocket.h).
3136 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
3137 Missing declarations added.
3139 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
3141 * struct.c: Uninitialized variable `SCM answer' may be used.
3143 * unif.c (l2ra): Declaration prototype.
3145 * unif.c (scm_array_equal_p): Dummy definition removed (it is
3146 defined in ramap.c).
3148 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
3149 Redundant declarations removed (they are in ramap.h).
3151 * variable.h (scm_make_udvariable,
3152 scm_make_undefined_variable): Declaration corrected to
3153 correspond variable.c.
3155 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
3156 Missing declarations added.
3158 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
3160 * Makefile.in (distclean): Don't forget to delete fd.h.
3162 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3164 * fd.h.in, tags.h: Trivial cleanups.
3166 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
3167 marksweep.h just declared functions from gc.c.
3168 * gc.h, libguile.h: Don't #include "marksweep.h".
3169 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
3170 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
3171 dependencies updated.
3173 * libguile.h: Don't #include "files.h"; it's been deleted.
3175 * files.c (scm_sys_delete_file): Moved to filesys.c.
3176 File is now empty; deleted.
3178 * filesys.c: scm_sys_delete_file is now here. Remove
3179 #if's; they seem to rely on remnants of an old portability
3180 regimen. If the problems come up again, solve them properly,
3181 using autoconf. Specifically: Don't test M_SYSV, and #define
3182 remove to be unlink if it's #defined; don't use remove just
3183 because HAVE_STDC_HEADERS is #defined.
3184 * filesys.h: Add declarations for scm_sys_delete_file.
3185 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
3186 files.o, files.h, files.c, and files.x.
3187 * init.c: Don't #include "files.h", and don't call scm_init_files.
3189 Use SCM_P instead of PROTO; the latter intrudes on the user's
3191 * params.h: Deleted; definition of SCM_P moved to...
3192 * __scm.h: ... here, where it replaces PROTO macro.
3193 * libguile.h, smob.h: Don't #include "params.h".
3194 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
3195 smob.h: Fix prototypes accordingly.
3196 * Makefile.in: Update dependencies.
3197 (inner_h_files): Remove params.h.
3199 * gc.c: #include "gc.h"; every module should include its header,
3200 to let the compiler cross-check the declarations against the
3203 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
3204 simpos.h: #include "libguile/__scm.h".
3206 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
3208 * init.c: Don't forget to #include smob.h and init.h.
3209 * Makefile.in: Dependencies updated.
3211 * smob.h: Use PROTO instead of #if __STDC__.
3213 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
3215 * __scm.h: Doc fixes.
3217 * __scm.h, libguile.h: Use "quotes" in the #includes, not
3218 <angles>; this allows `make depends' to work properly.
3220 * libguile.h: #include smob.h and pairs.h before the others; they
3221 define typedefs used by other headers.
3223 C files should #include only the header files they need, not
3224 libguile.h (which #includes all the header files); the pointless
3225 recompilation was wasting my time.
3226 * Makefile.in (all .o dependency lists): Regenerated.
3227 * libguile.h: Don't try to get a definition for size_t here...
3228 * __scm.h: Do it here.
3229 * _scm.h: Since this is the internal libguile header, put things
3230 here that all (or a majority) of the libguile files will want.
3231 Don't #include <libguile.h> here; that generates dependencies on
3232 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
3233 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
3234 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

3338 * smob.h: #include "ports.h", "genio.h", and "print.h", since
3339 anyone who uses this file will need them to define the smob
3340 printing functions. Also, get markers.h, since people will need
3341 to #define the mark functions.
3343 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
3344 * ports.h: ... to here.
3346 * ports.h (scm_port_table_size): Explicitly give type as 'int';
3347 don't rely on archaic C default type rules.
3349 * fports.h: #include "libguile/ports.h", since you need that in
3350 order to parse this.
3352 * genio.h: #include "libguile/print.h", because you need that to
3353 parse this; don't bother #including "ports.h", since print.h gets
3356 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
3358 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
3359 this; it's now a reference to an element of *scm_root.
3361 * debug.h: Don't #include "options.h"; the compiler won't be able
3362 to find that once the headers are installed; instead, #include
3363 "libguile/options.h".
3364 * gc.h: Same, with marksweep.h.
3365 * mbstrings.h: Same, with symbols.h.
3366 * scmhob.h: Same, with _scm.h.
3367 * smob.h: Same, with params.h.
3369 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
3370 C files; there's no need for this, and it forces recompilations
3373 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
3375 * error.c (scm_error): declare scm_error_callback.
3377 * error.h: prototype for scm_error_callback.
3379 * __scm.h: define lgh_error.
3380 (SCM_SYSERROR): redefine using lgh_error.
3382 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
3384 * error.c (scm_error): new procedure.
3386 * error.h: prototype for scm_error.
3388 * Makefile.in (install): install scmconfig.h from the current
3389 directory, not $(srcdir).
3391 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3393 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3394 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3395 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
3396 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
3397 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
3398 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
3399 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
3400 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
3401 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3402 vports.h, weaks.h: #include "libguile/__scm.h", not
3403 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
3404 dependencies are within libguile properly.
3406 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
3408 * Makefile.in (.c.x): Simplify; there's no need to run this rule
3409 when scmconfig.h doesn't exist.
3411 * load.c (scm_sys_try_load): Correct spelling.
3413 * feature.c (scm_loc_features): Make this static.
3415 * Makefile.in (libpath.h): Omit trailing slash from path. We
3416 shouldn't require it of users, so why put it here?
3418 Move code to initialize and search %load-path from ice-9 to C
3419 code, so we can use the load-path to find the ice-9 boot code;
3420 this makes it easier to run Guile without installing it. See
3421 corresponding changes in guile/Makefile.in.
3422 * feature.c: Move stuff concerned with the load path to load.c.
3423 (scm_compiled_library_path): Deleted.
3424 Don't #include libpath.h here.
3425 * feature.h: Don't mention scm_compiled_library_path.
3426 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
3427 <sys/stat.h>, and <unistd.h> (if present).
3428 (R_OK): #define if the system hasn't deigned to.
3429 (scm_loc_load_path): New variable.
3430 (scm_init_load_path, scm_sys_search_load_path,
3431 scm_sys_try_load_path): New functions.
3432 (scm_init_load): Initialize scm_loc_load_path to point to the
3433 value cell of the Scheme %load-path variable.
3434 * load.h: Add declarations for scm_sys_search_load_path,
3435 scm_sys_try_load_path.
3436 * init.c: Call scm_init_load_path.
3437 * Makefile.in (feature.o, load.o): Dependencies updated.
3439 * load.c, load.h: Rewrite using PROTO macro.
3441 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3443 * gc.c (scm_cellp): New function: C predicate to determine if an
3444 SCM value can be regarded as a pointer to a cell on the heap.
3446 * gc.h: Added declaration of scm_cellp.
3448 * gdb_interface.h: New file: The GDB interface header from the GDB
3451 * gdbint.c: New file: GDB interface.
3453 * gdbint.h: New file: GDB interface.
3455 * libguile.h: Added #include <libguile/gdbint.h>.
3457 * init.c (scm_boot_guile): Added scm_init_gdbint.
3459 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
3460 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
3461 found if object files and source are kept separate).
3463 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
3465 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
3467 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
3469 * configure.in: Don't substitute the values of TCL_SRC_DIR and
3470 TK_SRC_DIR; they're not relevant any more.
3472 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
3473 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
3475 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
3477 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
3478 search path, so we can find the <libguile/MUMBLE.h> headers.
3480 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
3482 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
3483 implicit in the .c.o rule.
3484 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
3487 Put the library path in a header file, instead of passing it on
3488 the command line in every compilation.
3489 * Makefile.in (libpath.h): New target.
3490 (feature.o): Depend on libpath.h.
3491 (clean): Delete libpath.h.
3492 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
3493 * feature.c: ... #include "libpath.h" here.
3494 * .cvsignore: Ignore libpath.h.
3496 Don't install the unwashed masses of Guile header files in the
3497 main #include path; put most of them in a subdirectory called
3498 'libguile'. This avoids naming conflicts between Guile header
3499 files and system header files (of which there were a few).
3500 * Makefile.in (pkgincludedir): Deleted.
3501 (innerincludedir): New variable; this and $(includedir) are enough.
3502 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
3503 (installed_h_files): Divide this up. Now this variable lists
3504 those header files which should go into $(includedir) (i.e. appear
3505 directly in the #include path), and ...
3506 (inner_h_files): ... this new variable says which files appear in
3507 a subdirectory, and are referred to as <libguile/mumble.h>.
3508 (h_files): List them both.
3509 (install): Create innerincludedir, not pkgincludedir. Put
3510 the installed_h_files and inner_h_files in their proper places.
3511 (uninstall): Corresponding changes.
3512 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
3513 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
3514 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
3515 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
3516 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
3517 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
3518 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
3519 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
3520 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
3521 vports.h, weaks.h: Find __scm.h in its new location.
3522 * __scm.h: Find scmconfig.h and tags.h in their new locations
3523 (they're both "inner" files).
3525 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
3527 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
3529 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3531 * posix.c: Doc fixes.
3533 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
3535 * socket.c: Don't include a prototype for inet_aton; just use a
3536 K&R style declaration, to avoid warnings but minimize the chance
3537 of conflicts with the system.
3539 On NextStep, <utime.h> doesn't define struct utime, unless we
3540 #define _POSIX_SOURCE before #including it.
3541 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
3542 * acconfig.h: New comment text for above CPP symbol.
3543 * configure.in: Call it.
3544 * posix.c: #define _POSIX_SOURCE if it seems necessary.
3546 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
3548 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
3549 testing for __EMX__.
3551 * posix.c: #include <libc.h>, if it exists.
3553 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
3554 don't even know if the latter exists.
3556 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
3557 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
3558 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
3560 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
3562 (scm_init_posix): Use them when initializing the Scheme constants
3565 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3567 * Makefile.in (libdir, includedir, bindir): Use the
3568 autoconf-supplied values, instead of deriving them ourselves.
3569 (pkgincludedir, datadir, pkgdatadir): New variables.
3570 (install, uninstall): Put the header files in a special
3571 subdirectory, not in the main search path.
3573 * Makefile.in (ALL_CFLAGS): Provide the proper value for
3574 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
3576 * Makefile.in (IMPLPATH): Deleted; never used.
3578 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
3579 on the Tcl/Tk source any more.
3580 (INCLUDE_CFLAGS): Remove references to the above.
3582 * Makefile.in (version.o): Corrected dependencies.
3584 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
3586 * libguile.h: #include "version.h"
3588 * init.c (scm_boot_guile): Call scm_init_version.
3589 * gscm.c (gscm_run_scm): Call scm_init_version.
3591 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
3592 GUILE_VERSION): AC_DEFINE these.
3593 (acconfig.h): #undef the above symbols.
3595 * Makefile.in (libobjs): Add version.o.
3596 (installed_h_files): Add version.h.
3597 (c_files): Add version.c.
3598 (gen_c_files): Add version.x.
3599 (version.o): New rule.
3600 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
3601 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
3602 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,

3604 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
3605 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
3606 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
3607 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
3608 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
3609 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
3610 weaks.o): Add version.h to dependency lists.
3611 (markers.o): Remove duplicate rule.
3613 * version.h: New file.
3615 * version.c: New file.
3617 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
3619 * symbols.c (scm_strhash): scm_downcase is now a function, not an
3620 array; use it appropriately. Since GCC is quite happy to
3621 subscript functions, it never warned us about this; we should use
3622 -Wpointer-arith in the future. I guess we never tested
3625 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3627 * socket.c: Doc and copyright fixes.
3629 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3631 * debug.c: Fixed and improved gdb support.
3633 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3635 * socket.c: Added declaration of inet_aton to avoid compiler
3636 warning. (Hope this solution is correct.)
3638 * stime.c: Added declaration of ftime. (This is missing in
3641 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
3643 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3645 * Makefile.in (c_files): add strerror.c.
3647 * strerror.c: new file from Emacs' sysdep.c.
3648 maybe configure should also check for sys_errlist.
3650 * configure.in (AC_REPLACE_FUNCS): add strerror.
3652 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3654 * debug.c (scm_init_debug): Added initialization for
3655 scm_evaluator_traps.
3657 * debug.h, debug.c: Various name changes.
3658 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
3659 "debug-options-interface". See commentary in options.c.
3661 * options.h, options.c: Options now have documentation strings.
3662 Also added a long explanatory commentary.
3664 * eval.c, print.h, print.c, read.h, read.c: Modifications to
3667 * gscm.c, init.c, root.c, throw.c: Bug fixes:
3668 last_debug_info_frame is now updated in all cases.
3670 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
3673 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3675 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
3676 Added option STACK_CHECKING.
3678 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
3680 * Makefile.in: Added {debug,options,srcprop}.{h,c}
3682 * __scm.h: Removed symbols for debugging support.
3684 * acconfig.h: Added symbols for debugging support.
3686 * configure.in: Added user option for debugging support.
3687 --enable-debug will include the debugging code into libguile.a.
3689 * continuations.c (scm_make_cont): Enlarged the #if 0 around
3690 scm_relocate_chunk_to_heap.
3692 * debug.c: New file: low-level debugging support. It also
3693 includes support for debugging with gdb. (The extensions to gdb
3694 are written by Per Bothner at Cygnus.)
3696 * debug.h: New file: low-level debugging support.
3698 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
3699 argument pairs. Extensive modifications to the debugging
3700 evaluator. Added "SECTION:" commentaries to clarify what happens
3701 when, during double compilation. Renamed EVALIMP --> EVALIM.
3702 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
3703 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
3704 the beginning of the file. New procedure: scm_unmemocopy.
3705 Added some global state variables needed by the debugging
3706 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
3707 check_entry, check_apply, check_exit, debug_options and
3708 evaluator_traps. New acro: undefine.
3710 * eval.h: Renamed EVAL --> XEVAL.
3712 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
3713 --> scm_make_weak_key_hash_table.
3715 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
3716 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
3718 * libguile.h: Conditionally include debug.h
3720 * objprop.c (scm_object_properties, scm_set_object_properties_x):
3721 scm_object_properties shouldn't return handle. `handle' now gets
3722 initialized in scm_set_object_properties_x. scm_object_properties
3723 doesn't any longer create an entry in scm_object_whash.
3725 * options.c: New file: handling of run time options.
3727 * options.h: New file: handling of run time options.
3729 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
3731 * print.c: New procedure: scm_print_options
3733 * print.h: Defines for print options.
3735 * read.c: New procedure: scm_read_options
3737 * read.h: Defines for reader options.
3739 * root.h: Added scm_source_whash among scm_sys_protects.
3741 * srcprop.c: New file: source properties.
3743 * srcprop.h: New file: source properties.
3745 * throw.c (jbsmob): Jump buffers are now correctly allocated.
3746 (Bug found by A. Green.)
3748 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3750 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
3752 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
3754 * libguile.h: #include "objprop.h"; I guess this was forgotten.
3756 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
3757 and should be called by the final client.
3759 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
3761 * gc.h: Use the PROTO macro when declaring functions.
3762 * gc.c: Use the PROTO macro when declaring static functions.
3763 Remove the CPP hair around function definitions.
3765 * gc.c (scm_init_storage): Initialize scm_asyncs.
3767 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
3768 preprocessor symbol; "__scm.h" is where it might get #defined.
3769 * __scm.h: Similar: #include <scmconfig.h> before testing
3772 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
3774 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
3776 * init.c (scm_boot_guile): Add init_func argument; call
3777 (*init_func) instead of calling scm_appinit; it's ucky to
3778 hard-code names for the user's procedures.
3779 * init.h (scm_boot_guile): Adjust declaration.
3781 * __scm.h (PROTO): New macro, for declaring functions with
3784 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
3785 eliminate all the __STDC__ conditionals.
3786 (scm_boot_guile): Add declaration.
3787 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
3788 Remove __STDC__ conditionals around function definitions; the
3789 declarations in init.h will provide the same information, more
3792 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
3793 complain about it in the error message; the error message is
3794 adequate without that note, and there's nothing the user can do
3797 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
3799 * Makefile.in (ancillary): Drop def.sed.
3801 * posix.c (scm_init_posix): Use numeric values, rather than
3802 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
3803 F_OK. The symbols aren't available on some systems, and I'm
3804 pretty sure their values are fixed by common widespread practice.
3805 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
3807 More functions unavailable on some systems.
3808 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
3809 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
3811 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
3812 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
3813 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
3814 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
3815 stub that signals an error as the #else.
3817 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.

3874 NeXT. Put header file list in alphabetical order.
3875 * configure, scmconfig.h.in: Regenerated.

3913 Remove duplicate entries for markers.h and unif.h.

3921 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
3922 every if must have an else, or else the whole command has a

3992 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
3994 * gscm.h: gscm_mkarray eliminated (presumably was not being used
3995 since its definition was bogus).

3999 * mallocs.[ch]: back again (for rx at least).
4001 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
4003 * ports.c: removed functions relating to the mapping between ports
4004 and descriptors. (That stuff is unix-specific and should be collected
4005 in a separate library).

4012 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
4013 handled correctly (SCM_FREEP was applied to them) -- test for
4014 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

4208 set the multi_byte flag correctly in symbols. This is wrong.
4209 intern_obbary_soft and msymbolize should take an extra parameter.

4379 scope created by scm_with_dynamic_bindings_operation_x, swap
4380 the bindings of that scope with the corresponding globals.
4382 * continuations.c (scm_make_cont): when a continuation is captured,
4383 relocate the continuation stack chunks registered on the wind chain

4388 * eval.c (SCM_CEVAL): if the function position evaluates
4389 to a macro, process it accordingly. (Previously, macros were
4390 handled only if the function position was a symbol naming a
4391 variable bound to a macro).

4395 * eval.c (scm_m_set): allow multi-variable set! like
4398 Wed Dec 6 02:40:49 1995 Tom Lord <lord@beehive>
4400 * ports.h fports.c vports.c marksweep.c gc.c strports.c: moved the
4401 STREAM of ports into the port table and replaced it with a
4404 * repl.c (iprin1): added tc7_mb_string -- same as tc7_string.
4406 * marksweep.c (scm_gc_mark): added tc7_mb_string -- same as tc7_string.
4408 * mbstrings.c (new file): functions on multi-byte strings.
4410 * tags.h (scm_typ7_string, scm_typ7_mb_string): added a tag
4411 for multi-byte strings. Moved the string tag.
4413 * chars.h chars.c repl.c (many functions): made scm_upcase and
4414 scm_downcase functions that are safe for extended character sets.
4416 Changed the range of integer->char.
4418 Changed the type of SCM_ICHR.

4427 * guile.c (gscm_is_gscm_type): New function. (Without this how will we
4428 know that it's safe to pass an object to gscm_get_type?)
4429 (gscm_get_type): Fix tyop in error message.
4431 * variable.c (scm_variable_ref): fixed assertion test.
4432 (Robert STRANDH <strandh@labri.u-bordeaux.fr>)
4434 * gscm.h: fixed several prototypes, notably gscm_vref.
4435 Add gscm_is_eq and temporarily commented out gscm_eq (see
4436 the note in gscm.h near gscm_eq if this change effects your

4440 * pairs.c (scm_obj_length): see next entry.
4442 * gscm.h (gscm_obj_length): A way to get an integer

4447 (William Gribble <grib@arlut.utexas.edu>)
4449 * Makefile.in (X_CFLAGS): defined.
