1 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
3 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
5 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
7 * eval.c (safe_setjmp): Remove this misunderstanding.
8 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
11 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
13 * libguile.h: Mark these as C declarations, for compilation by C++
16 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
17 __cplusplus clause. I seriously doubt this ever worked the way
18 the author seems to have intended.
20 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
22 Utterly needless cleanups to hopelessly messy code.
24 (scm_fflush): Moved to ...
25 * genio.c (scm_fflush): ... here, amongst all the other port
26 method invocation functions.
27 * genio.h, ports.h: The prototype moves too.
29 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
31 * backtrace.c (display_error_body): The current frame does not
32 always have a parent frame; consider a function called directly
33 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
36 * alloca.c (alloca): Undo yesterday's changes, and simply call
37 malloc directly for storage, and abort if we don't get what we
38 want. The situation is much simpler --- just call malloc. Emacs
39 has bizarre/evil requirements (signal handlers might malloc unless
40 you set this global flag, so you have to set the flag around all
41 calls to malloc) which we are certainly not going to conform to,
42 so we can do the simple and obvious thing.
44 * coop.c (coop_condition_variable_wait): Make this function
45 static. It's only useful internally --- you should never just
46 wait on a condition variable.
47 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
49 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
51 * unif.c (scm_array_set_x): Accept any kind of number as an
52 element for a uniform vector of doubles. This is more consistent
53 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
55 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
56 works; I can't conveniently test it myself. (Thanks to Dvid
57 Tillman for the bug report.)
61 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
62 from here, not from scm_compile_shell_switches (which is a pretty
64 (scm_load_startup_files): New function.
65 (scm_ice_9_already_loaded): Variable moved to here from script.c.
66 * script.c (scm_compile_shell_switches): Don't load the startup
68 (scm_ice_9_already_loaded): Variable moved.
69 * init.c (scm_load_startup_files): Prototype for new function.
70 * gh_init.c (gh_enter): Doc fix.
72 1998-10-03 <jimb@savonarola.red-bean.com>
74 Some anti-warning changes from Greg Harvey.
75 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
76 warnings when it doesn't understand our NORETURN declarations in
78 * posix.c (scm_mknod): Similar.
80 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
82 * posix.c (scm_getpwuid): If we can't find an entry, return our
83 own message, instead of using scm_syserror --- the getpwMUMBLE
84 functions don't set `errno' to anything interesting.
86 1998-10-03 <jimb@savonarola.red-bean.com>
88 Get rid of warnings from the cooperative threading system.
89 * threads.h (scm_single_thread_p, scm_yield,
90 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
91 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
92 scm_wait_condition_variable, scm_signal_condition_variable): Add
93 prototypes for these Scheme-visible functions.
94 * coop-defs.h (coop_next_runnable_thread,
95 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
96 Prototypes for these here, even though they're from iselect.c.
97 (coop_condition_variable_wait, coop_join): Add prototypes.
98 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
99 scm_threads_free_condvar): Make these smob functions static.
100 * coop-threads.h (coop_init): Give this a real prototype.
101 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
102 (coop_next_runnable_thread): No need to provide prototype; it's in
105 * scmconfig.h.in: .detarenegeR
107 * iselect.c, threads.c: Doc fixes.
109 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
111 * Makefile.in: Regenerated with a patched automake, to get
112 dependency generation right when using EGCS.
114 * inet_aton.c (inet_aton): Add prototype, to remove compiler
115 warning. (Thanks to Robert Pluim.)
117 * inet_aton.c (inet_aton): Reassure the compiler that the
118 arguments to the <ctype.h> macros are all unsigned characters, not
121 1998-10-03 <jimb@savonarola.red-bean.com>
123 Getting rid of more warnings...
124 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
125 today's change to ../configure.in.
126 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
127 * scmconfig.h.in: Regenertaded.de.,.__
128 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
129 (scm_localtime, scm_mktime): Use a const char * to manipulate the
132 * readline.c: Doc fix.
133 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
134 * readline.h (scm_filename_completion_function): Add prototype.
135 (scm_init_readline): Make this into a prototype.
137 * readline.c (scm_filename_completion_function): Use SCM_PROC to
138 declare this, instead of calling scm_make_subr manually.
140 1998-10-02 <jimb@savonarola.red-bean.com>
142 * readline.h (scm_init_readline): Add prototype for this.
143 (scm_init_readline): Make this a real prototype.
145 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
147 Warning fixes from Maciej Stachowiak:
148 * backtrace.h (scm_display_application, scm_backtrace): Add
150 * debug.c (scm_m_start_stack): Make this function static.
151 * fluids.h (scm_fluid_p): Add prototype.
152 * procprop.c (scm_i_procedure_arity): Make this function static.
153 * regex-posix.c (scm_regexp_error_msg): Make this function static.
154 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
155 * root.h (scm_dynamic_root): Add external prototype.
156 * scmsigs.h (scm_usleep): Add external prototype.
157 * script.h (scm_init_script): Use prototype, not K&R decl.
158 * stacks.h (scm_stack_id): Add external prototype.
159 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
161 1998-09-30 Mark Galassi <rosalia@cygnus.com>
163 * gh.h: took out the definitions of vset and vref, since they are
164 replaced by the proper vector routines that correspond to the R4RS
167 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
169 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
170 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
171 third argument, a C expression that should result in a SCM value,
172 which is used to initialize the variable. Reimplemented
173 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
176 * version.h (scm_libguile_config_stamp): Add prototype.
177 (From Maciej Stachowiak.)
179 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
181 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
182 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
184 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
186 * print.c (scm_iprin1): Rather than having one i, and using it in
187 several places, declare a fresh i local to each block where it is
188 used, and give it a signedness appropriate to its use in each case.
191 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
194 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
195 signed/unsigned clashes.
197 * posix.h (scm_tmpnam): Added prototype.
199 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
200 scm_make_subclass_object): Add external prototypes.
202 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
203 comparison is okay here.
205 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
207 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
208 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
210 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
213 * load.c (swap_port): Make this function static.
215 * load.c (scm_search_path): Make max_path_len and max_ext_len
216 unsigned, since they're compared against string sizes.
218 * load.c (init_build_info): Make i unsigned.
220 * ioext.h (scm_read_line): Add prototype.
222 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
223 scm_hash_fn_remove_x): Make hash bucket index local variable k
224 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
225 accurately as possible.
227 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
228 comparisons, and range checking to make sure those casts are
231 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
232 signed/unsigned comparisons.
234 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
235 avoid signed/unsigned comparisons.
236 * smob.h (scm_numsmob): Change extern declaration to match.
238 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
239 avoid signed/unsigned comparisons.
240 * ports.h (scm_numptob): Change extern declaration to match.
241 (scm_current_load_port, scm_set_port_line_x,
242 scm_set_port_column_x): New prototypes.
244 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
245 test code, and it causes warnings.
247 * gh.h (gh_int2scmb, gh_uniform_vector_length,
248 gh_uniform_vector_ref): Added prototypes.
250 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
251 debugging support unconditionally. That's backtrace.c, stack.c,
252 debug.c, and srcprop.c.
253 (EXTRA_libguile_la_SOURCES): Omit those from here.
254 * Makefile.in: Regenerated.
256 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
258 * options.c (scm_options): Bugfix: Allow empty list of options!
260 * debug.c, debug.h (scm_single_step): Removed.
261 (scm_with_traps): New procedure. This procedure could easily be
262 written in Scheme but needs to be highly optimized.
264 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
266 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
267 Check SCM_TRAPS_P before trapping.
269 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
271 Changes to avoid signed/unsigned comparison warnings.
272 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
273 (scm_gc_sweep): Make n and j local to the blocks they're used in,
274 so they can have appropriate types for each application. Make i
275 signed. Use initializers in some spots. I'll probably pay for
277 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
278 (scm_must_realloc): Make nm unsigned.
279 (init_heap_seg): Make new_seg_index and n_new_objects signed.
280 (scm_init_storage): Use prototype-style definition, and make the
282 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
283 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
285 * filesys.c (scm_readlink): Make local vars rv and size ints, to
286 avoid signed/unsigned comparison warnings, and because the return
287 value of readlink may be -1. Don't bother casting the third
288 argument to readlink.
290 * filesys.c (scm_dirname, scm_basename): Move these to their own
291 page, at the end of the file.
292 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
294 * eval.h (scm_eval_options_interface): Add external prototype for this.
295 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
297 * eval.c (scm_lookupcar1): Make this static.
299 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
300 Make these prototype declarations, not K&R-style.
302 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
303 unsigned comparison warning.
305 * appinit.c: File removed. It had a single function in it, empty,
306 whose reason for existence is explained in no documentation or
307 comment. I think it's there as a default for some Tcl-style
308 initialization, but Tcl abandoned that approach a while ago.
309 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
310 (BUILT_SOURCES): Remove appinit.x.
311 * Makefile.in: Regenerated.
313 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
315 * Makefile.in: Regenerated using the last public version of
316 automake, not the hacked Cygnus version.
318 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
320 Remove Totoro kludge.
321 * Makefile.in, scmconfig.h.in: Regenerated.
322 * init.c, readline.c: Don't check if TOTORO is #defined.
324 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
326 * Makefile.am: Adjust for new thread configuration system.
327 (INCLUDES): Include the value of THREAD_CPPFLAGS.
328 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
330 (THREAD_LIBS): Definition deleted; automake will generate such
331 things automatically.
332 * Makefile.in: Regenerated.
334 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
336 Simplify smob and port marking; set the mark bit in the generic
337 marking code, and make marker routines only responsible for
338 turning up outgoing pointers.
339 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
340 before calling the marking function. Don't call the marking
341 function if it's zero.
342 * markers.c (scm_mark0): Just return #f. This function isn't
343 necessary at all now, but it's harmless to call it. We'll leave
344 it in so other folks' code doesn't croak at link time.
345 (scm_markcdr): Don't call SCM_SETGC8MARK.
346 * async.c (mark_async): Don't call SCM_SETGC8MARK.
347 * dynl.c (mark_dynl_obj): Same.
348 * root.c (mark_root): Same.
349 * srcprop.c (marksrcprops): Same.
350 * unif.c (markra): Same.
351 * variable.c (scm_markvar): Same.
352 * ports.c (scm_markstream): Same.
353 (void_port_ptob): Specify zero for our marking function.
354 * debug.c (debugobjsmob): Same.
355 * dynwind.c (guardsmob): Same.
356 * filesys.c (dir_smob): Same.
357 * fluids.c (fluid_smob): Same.
358 * fports.c (scm_fptob, scm_pipob): Same.
359 * mallocs.c (mallocsmob): Same.
360 * regex-posix.c (regex_t_smob): Same.
361 * smob.c (freecell, flob, bigob): Same.
362 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
363 * throw.c (jbsmob, lazy_catch_funs): Same.
365 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
367 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
368 scm_copy_tree on code in order not to let memoized code to leak
369 out. Thus, scm_copy_tree needs to copy vectors as well since
370 quasiquote can introduce evaluated code also inside vector
373 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
375 * eval.c (scm_copy_tree): Removed ability to copy vectors.
377 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
378 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
381 * unif.c: Say that ivect and uvect are of type signed and unsigned
382 long instead of int in commentary so that it correctly describes
385 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
387 * stime.c: Removed declaration of strptime. (It should be
388 declared by the system headers. If it turns out that some systems
389 don't, we'll handle that then.) (Thanks to Greg Troxel.)
391 * stime.h: Renamed TIMEH --> STIMEH
393 * backtrace.c (scm_display_error, scm_display_backtrace): In order
394 to increase portability, don't use structure assignment.
395 (Thanks to Nicolas Neuss.)
397 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
399 (finalize_fd_sets): Added empty statement after last case label.
400 (Thanks to Nicolas Neuss.)
402 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
405 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
407 * init.c, readline.c: OK, I won't have these readline.x bug
408 reports anymore. We've had them since April. The current reason
409 is a completely unintelligible failure of totoro.red-bean.com to
410 do the test for rl_getc_function in libreadline correctly. This
411 kludge overrides the test if we're on totoro so that the snapshot
412 generation process can work.
414 * readline.c: Define a strdup replacement if not existent on system.
416 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
418 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
419 This change makes scm_make_vector R5RS compatible. We cannot keep
420 the third argument since people want to be able to deduce the form
421 of the C function call only by looking at R5RS. (At the same time
422 we have removed some unnecessary complexity!)
424 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
425 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
426 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
427 argument in call to scm_make_vector.
429 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
431 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
432 This macro is useful in applications.
434 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
436 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
437 (scm_parse_path, scm_search_path): New Scheme level procedures.
439 * load.h (scm_internal_parse_path, scm_parse_path,
440 scm_search_path): Declared.
442 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
444 * filesys.c (dirname, basename): New procedures.
446 * init.c (scm_boot_guile_1): Removed condition around
449 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
450 new data type (guards) for representation of C level guards and
451 data on the wind chain.
452 (scm_internal_dynamic_wind): New function.
454 * dynwind.h: Declare scm_internal_dynamic_wind.
456 * root.h (scm_root_state): Added scm_cur_loadp.
458 * root.c (mark_root): Added comment about cur_loadp.
460 * load.c: #include "dynwind.h";
461 (scm_primitive_load): Use scm_inner_dynamic_wind to update
464 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
466 * ports.c (current-load-port): New procedure.
468 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
470 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
471 not a tty, return #f.
473 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
474 to Julian Satchell and Roland Kaufmann.)
476 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
477 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
479 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
481 * debug.h, debug.c (scm_start_stack): New function. Implements
482 the guts of old scm_m_start_stack.
484 * debug.c (scm_m_start_stack): Use scm_start_stack.
486 * init.c (scm_start_stack, scm_restart_stack): Renamed to
487 start_stack and restart_stack. (These have static scope.)
489 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
491 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
492 readline functions to come in release 2.3. (Thanks to Chet
494 (handle_errors): Use the above functions.
496 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
498 * readline.c: Improvements for readline support: Handle errors
499 better; Implement before-read-hook.
501 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
503 * init.c (scm_boot_guile_1), readline.c: Test for
504 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
505 assure that we have version >= 2.1.)
507 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
509 * readline.c (scm_readline): Defer interrupts while we're calling
512 * readline.c (scm_add_history): Bugfix: Do strdup before giving
513 away the string to add_history.
514 (completion_function): Do completion for readline. (Thanks to
516 (scm_filename_completion_function): New procedure: Filename
518 (current_input_getc): New function. Use this one instead of
519 standard getc from readline.
521 * throw.c, throw.h (scm_handle_by_throw): New function: This
522 handler throws errors to next handler on the dynwind chain.
524 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
526 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
529 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
531 * procprop.c (scm_i_procedure_arity): New function. Returns arity
533 (scm_procedure_properties): Modified to return arity together with
535 (scm_procedure_property): Added the read-only property `arity'.
536 (scm_set_procedure_property_x): It is an error to set the `arity'
539 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
540 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
542 * procprop.h (scm_sym_arity): New symbol.
544 * objects.c (scm_set_object_procedure_x): New procedure: Use this
545 to set the dispatch procedure of an operator or entity object.
547 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
548 Made procedure slots read-only.
550 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
551 scm_tcs_cons_gloc case in zero args switch; Fixed args
552 construction for operators in scm_tcs_cons_gloc case in two args
555 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
557 * fluids.c: Removed use of assert.h (in order to avoid
560 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
562 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
564 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
565 change makes the evaluator safer at the cost of evaluation speed.
566 It handles the case when the user has added a non-immediate
567 improper end of the application form, e.g., `(+ 0 . x)'.
568 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
569 minimize the extra cost as much as possible. The new code is
570 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
571 problem with structs planted directly in the code (e.g. by a
572 macro). This no longer causes segmentation fault. (Thanks to
575 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
576 arg `proc' in order to be able to throw errors; New argument
579 * Removed extra #include "debug.h"
581 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
583 * scmsigs.c: Declare usleep as returning void on some systems.
584 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
587 * coop.c (usleep): Return void on some systems.
589 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
591 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
593 * coop.c: Changed return type of usleep to int.
595 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
596 isn't found in the OS.
598 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
599 isn't enabled. (Thought that I had made this change ages ago...)
601 * iselect.c: Declare bzero if not defined by OS.
603 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
605 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
606 condition. (Thanks to John Tobey.)
608 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
609 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
612 * __scm.h: Start the long-term project of moving to POSIX threads.
613 Phase 1: Classification of all critical sections.
614 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
615 for A sections. (See comments in __scm.h for details.)
617 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
618 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
620 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
622 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
623 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
624 (libpath.h, versiondat.h): Replaced dependency on Makefile with
625 dependencies on $(srcdir)/Makefile.in
626 $(top_builddir)/config.status in order to avoid circularity.
628 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
629 from argc if argc was 0 initially.
631 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
632 in generation of libpath.h.
634 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
636 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
637 libguile from 2 to 3.
639 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
641 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
643 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
645 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
646 scm_set_port_column_x, scm_port_filename,
647 scm_set_port_filename_x): Removed optional arguments. Added
648 proper argument checking.
650 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
651 stack size in machine words.
653 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
654 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
655 to Ole Myren Röhne.)
657 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
659 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
660 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
662 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
665 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
666 procedure apply: Copy argument lists before pushing them unto the
667 environment so that the environment won't get mutated due to
668 manipulation of procedure arguments. This should perhaps be
669 regarded as a temporary solution until someone finds a more
670 efficient one. (Thanks to Maciej Stachowiak.)
672 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
674 * script.c (scm_compile_shell_switches): Use "guile" as default
675 zero arg if argc is NULL.
677 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
679 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
680 is zero. (Thanks to Dirk Herrmann.)
682 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
684 * ports.c (scm_add_to_port_table): First line is now line 0
685 (was 1). (Interface changed according to suggestion by Per
688 * backtrace.c (display_header): Add 1 to line and column numbers
689 when presenting them to the user.
691 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
692 from debug.c --> eval.c
694 * eval.h, eval.c (scm_eval_options_interface): New options
696 (SCM_EVAL_STACK): New option: Size of newly created stacks,
697 i.e. stacks for new threads.
699 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
701 * eval.c (unsafe_setjmp): Removed with #if 0.
703 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
706 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
707 to avoid compiler warnings.
709 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
711 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
713 * throw.c (handler_message): Print message on current error port
714 instead of default error port. (Thanks to Maciej Stachowiak.)
716 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
718 * ports.c (scm_add_to_port_table): allocate in units of
719 struct scm_port_table *, not struct scm_port_table.
720 * posix.c (scm_close_pipe): remove the port from the port table
722 Thanks to Rob Engle for both fixes.
724 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
726 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
727 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
729 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
731 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
733 * backtrace.c (display_error_body, display_backtrace_body),
734 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
735 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
736 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
737 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
740 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
741 don't receive the jmpbuf arg anylonger.
742 (scm_catch): Don't accept a #f tag.
743 (scm_throw): Check that key is a symbol.
744 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
746 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
748 * async.c (async_pending): Removed declaration.
750 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
752 * dynwind.c (scm_wind_chain): New debug function.
754 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
755 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
756 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
757 extra layer of functions around the body and handler of a thread.
758 This extra layer makes sure that the handler is called in the
759 dynamic context of the surround (= empty dynwind list), but under
760 the *dynamic root* of the body. We can not use the dynamic root
761 of the surround since that root belongs to another thread => stack
762 is not handled correctly. It may seem ugly to use this extra
763 layer, but the extra cost in terms of execution time is really
764 negligible compared to the total amount of time required to create
765 a thread, and it would reduce maintainability to duplicate the
766 crucial and complicated steps performed by cwdr.
768 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
769 (SCM_ALLOW_INTS): Added thread switching code before interrupts
770 get re-enabled. The important effect of this is that interrupts
771 are blocked during thread switching so that thread data structures
772 don't risk getting messed up by an unfortunate signal.
773 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
774 seems to do more aggressive optimization which actually move
775 instructions around in these macros in a fatal way. Therefore:
776 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
777 just superstitious...)
778 (SCM_TICK): Maybe do a context switch and take care of asyncs.
779 This macro should be used instead of SCM_ASYNC_TICK since the
780 latter doesn't do context switches any more.
782 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
783 instead of SCM_ASYNC_TICK.
785 * coop.c, iselect.c: Since thread switches are now performed with
786 interrupts masked, we can't use the old mechanism of delivering
787 signals immediately when they arrive. Signals must instead be
788 delivered when the asyncs run *after* the end of the critical
789 section in scm_internal_select. But this also means after context
790 switch so that the signal will be delivered to a different thread.
791 To avoid this, I have changed the protocol of
792 coop_wait_for_runnable_thread and friends so that they are allowed
793 to return the original thread. So, if a signal arrives during
794 scm_internal_select, we won't any longer be forced do a context
795 switch, but can remain in the same thread and deliver the signal
798 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
799 scm_asyncs_pending and made it global.
801 * iselect.c: Small fixes.
803 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
804 coop_condition_variable_init, coop_condition_variable_wait,
805 coop_condition_variable_signal): Changed return type from `void'
806 to `int'. This is to adhere closer to the pthreads interface.
807 This, in turn, is part of an attempt to provide C versions of the
808 mutex and condition variable primitives which can be part of a
809 frontend to COOP or pthreads.
811 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
812 coop_condition_variable_destroy): New functions.
814 * coop-threads.c (scm_wait_condition_variable): Use
815 coop_condition_variable_wait_mutex.
817 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
818 Definitions moved to coop-defs.h.
820 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
821 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
822 scm_cond_destroy): New C interface to mutecis and cond vars.
824 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
826 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
828 * iselect.c: Now several threads can wait on the same file
829 descriptor. The behaviour is compatible with OS select: All
830 threads waiting for the fd return with the same status.
832 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
834 * coop-threads.c, threads.h (scm_spawn_thread): New function.
835 Can spawn a thread from application C code.
837 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
839 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
840 gh_doubles2scm): New functions.
842 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
844 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
845 commented-out version of gh_eval_str()
847 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
849 * socket.c (scm_bind): free soka after use.
851 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
853 * stime.c (tzvar): new variable.
854 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
855 avoid memory leaks when allocating.
857 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
859 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
862 * gc.c, tags.h: Doc fixes.
864 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
866 * eval.c (macro-eval!): Removed. This function was a design bug.
867 It allowed memoized code to leak out to the scheme level. Most
868 things that you could do with `macro-eval!' can be done with
871 1997-12-20 Tim Pierce <twp@skepsis.com>
873 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
874 scm_fgets now depends on ftell(3) to know how many bytes were
877 1997-12-15 Tim Pierce <twp@skepsis.com>
879 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
880 dealing with strings.
882 1997-12-13 Tim Pierce <twp@skepsis.com>
884 Make %read-line more suitable for implementing read-line efficiently.
885 * ioext.c (scm_read_line): Strip the terminating newline from a
886 string, and return a cons of the string and its terminator.
888 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
889 of the string that is read is stored in this memory location.
890 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
891 * genio.c, genio.h (scm_do_read_line): Update caller.
892 * ports.h (scm_ptobfuns): Update typedef.
893 * fports.c (scm_fptob, scm_pipob): Update struct.
895 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
897 * filesys.c (set_element): Return file descriptor.
898 (fill_select_type): Return the highest file descriptor.
899 (scm_select): Tell select about the highest file descriptor. On
900 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
901 Therefore the extra overhead for calculating the maximum fd seems
902 to be more than compensated. Is this correct? In any case,
903 scm_internal_select will be much faster with this info.
904 (scm_select, fill_select_type, set_element): Don't accept any kind
905 of object in the file descriptor list or vector.
907 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
909 * iselect.c (finalize_fd_sets): Bugfix.
911 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
913 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
914 when using scm_internal_select (since we might switch to another
917 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
919 * simpos.c (scm_system): always define: use sysmissing if not
920 available. Check for HAVE_SYSTEM instead of _Windows (does
921 Windows lack system or does it have an unusable one?).
922 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
923 Let the argument be optional: if not supplied, call system(NULL).
925 * ports.c (scm_close_port): relax the type check from OPPORTP to
926 PORTP; closing a closed port is allowed.
928 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
930 * fports.c (scm_fgets): Return if the last char in a chunk is
931 newline. When fgets returns a string whose length is `size-1', it
932 is ambiguous whether a whole line was retrieved, so we must check
933 explicitly whether a line terminator is present.
935 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
937 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
938 before taking the CDR. (Thanks to Harald Meland.)
940 * filesys.c (scm_stat): Slightly optimized.
942 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
944 * ports.c (scm_close_port): Make sure the port is open before
947 * guile-snarf.in: Pass args through to gcc in a way that preserves
948 whitespace boundaries. (Thanks to Greg Badros.)
950 1997-12-02 Tim Pierce <twp@skepsis.com>
952 * stacks.c (scm_frame_procedure): Reverse the logic in the return
953 statement. (Thanks to Doug Evans for pointing this out.)
955 1997-12-01 Tim Pierce <twp@skepsis.com>
957 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
959 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
961 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
962 errno macro expansion of this field name. (errno is a C
963 preprocessor macro on some systems.)
965 1997-11-29 Tim Pierce <twp@skepsis.com>
967 * iselect.c: Doc fix.
969 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
971 * init.c (scm_start_stack): Removed initialization of
972 scm_the_last_stack_var.
974 * backtrace.h: Declare scm_the_last_stack_var.
976 * backtrace.c: Define scm_the_last_stack_var.
978 * root.c (mark_root): Don't mark the_last_stack_var.
980 * root.h (scm_root_state): Removed the_last_stack_var.
982 * throw.c: Added #include "fluids.h"
983 (ss_handler): `the-last-stack' is now a fluid.
985 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
986 --> the_last_stack_fluid.
988 * backtrace.c: Added #include "fluids.h"
989 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
990 (scm_backtrace): `the-last-stack' is now a fluid.
992 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
993 after scm_init_fluids.
995 1997-11-28 Tim Pierce <twp@skepsis.com>
997 * iselect.c: #ifdef USE_THREADS around thread-related includes.
999 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1000 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1002 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1004 * iselect.c (coop_next_runnable_thread,
1005 coop_wait_for_runnable_thread): Disable interrupts so that no
1006 async is executed before a potential error_revive.
1007 (scm_internal_select): Disable interrupts during the parts of the
1008 code which manipulate the sleep queue and the file descriptors.
1010 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1012 * Makefile.am: Added iselect.c and iselect.h.
1014 * coop.c (coop_qinit): Initialize fields used by
1015 scm_internal_select.
1016 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1017 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1018 replacement in iselect.c.
1019 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1020 coop_join): If GUILE_ISELECT enabled, use
1021 coop_wait_for_runnable_thread instead of
1022 coop_next_runnable_thread.
1023 (usleep, sleep): New replacements for system functions if
1024 GUILE_ISELECT is enabled.
1026 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1028 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1030 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1031 iselect.h. Implement Scheme level `select' using
1032 scm_internal_select. (See NEWS.)
1034 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1036 * init.c: Call scm_init_iselect.
1038 * iselect.h, iselect.c: New files. Implements
1039 scm_internal_select. (See NEWS.)
1041 1997-11-27 Tim Pierce <twp@skepsis.com>
1043 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1044 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1045 and scm_must_free, since ultimately the string returned will be copied
1046 by scm_makfrom0str anyway. Also, read any characters that may have
1047 been pushed onto the port with scm_ungetc.
1048 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1049 * ioext.c (scm_read_line): Free string after Guilifying it.
1050 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
1052 1997-11-26 Anthony Green <green@hoser.cygnus.com>
1054 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
1056 * gh.h: Safely wrap prototypes for c++ usage.
1058 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1060 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1061 gh_repl (argc, argv).
1063 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1065 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1066 and to invoke scm_shell().
1067 (gh_launch_pad): took out the loading of boot-9.scm from here,
1068 since it is probably best to let the user control that. In fact,
1069 gh_repl() now invokes scm_shell() which does that.
1071 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1073 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
1076 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
1078 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
1079 yesterday's underscore patch. (Thanks to Marius Vollmer for
1082 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
1084 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
1085 DLSYM_ADDS_USCORE is not defined.
1087 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
1089 * gh_data.c (gh_uniform_vector_length):
1090 (gh_uniform_vector_ref): started implementing the uniform types in
1093 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1095 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1096 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1098 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1100 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1101 configure.in was changed).
1103 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
1105 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1106 * Makefile.in: Regenerated.
1108 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1110 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1111 OPORT is an `open' port, not an output port.
1113 * filesys.c (scm_close, set_element, get_element, scm_chown,
1114 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use

1118 scm_port_column, scm_set_port_column_x, scm_port_filename,
1119 scm_set_port_filename_x, scm_port_mode,
1120 scm_close_all_ports_except, scm_set_current_output_port,
1121 scm_set_current_error_port): Likewise
1122 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1123 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1125 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1126 * backtrace.c (display_backtrace_body): Likewise
1127 * fports (scm_setvbuf): Likewise
1128 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

1131 * unif.c (scm_uniform_array_write): Likewise
1133 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
1135 Minor problems with substring-related tag changes.
1136 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1137 exactly what we want to leave in to detect substrings.
1138 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1139 * tags.h: Fix diagrams and comments describing the S tag bit;
1140 remove vestigial remarks about the D tag bit.
1141 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1142 * strings.c: Formatting tweaks.
1144 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1145 variable first; then SCHEME_LOAD_PATH, with a warning message.
1146 (scm_parse_path): New function.
1147 * script.c: Doc fixes.
1149 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1151 Readline support, from Daniel Risacher.
1152 * readline.c, readline.h: New files.
1153 * init.c: #include "readline.h".
1154 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1155 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1156 * Makefile.in: Regenerated.
1157 * scmconfig.h.in: Regenerated, after change to ../configure.
1159 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1161 * gh.h: gh_vector_set -> gh_vector_set_x
1163 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1165 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1166 with the ! -> _x mapping when going from Scheme to C.
1168 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1170 * gh.h (gh_reverse):
1178 (gh_assoc): added these gh_ functions implemented as macros.
1180 * gh_predicates.c (gh_null_p):
1181 (gh_string_equal_p): added these two missing predicates.
1183 * gh_list.c (gh_append):
1188 (gh_set_cdr_x): added these routines as I go through and try to
1189 complete the picture R4RS functions that should be mirrored in the
1192 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1194 * tags.h (scm_tc7_substring): Changed the comment and code to
1195 conform with the changes below. Folks! We have suddenly two new
1196 free tc7 codes!!! Jummy, jummy!
1198 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1200 * Makefile.in: Rebuilt.
1201 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
1203 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
1204 * unif.c (scm_vector_set_length_x): Don't handle multibyte

1220 (SCM_TYP7D): Removed.
1221 (scm_tc7_mb_string): Removed.
1222 (scm_tc7_mb_substring): Removed.
1223 * print.c (scm_iprin1): Handle char printing directly. Don't
1225 Don't include "mbstrings.h".
1226 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
1227 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1229 Don't include "mbstrings.h".
1230 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1231 (SCM_SYMBOL_SLOTS): Define as 4.
1232 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
1233 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
1234 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
1235 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
1236 struct.c, threads.c, throw.c, unif.c, variable.c: Use new

1253 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
1254 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
1256 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1258 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1260 * gh_test_c.c (c_vector_test): some improvements on the vector
1263 * gh.h (gh_vector): this used to exist but do the wrong thing.
1264 Now it (almost) does the right thing, though it takes a list
1265 instead of the individual arguments. I need to see how it could
1267 (gh_list_to_vector): added this function as a macro. Corresponds
1268 to Scheme's (list->vector ...).
1269 (gh_vector_to_list): added this function as a macro. Corresponds
1270 to Scheme's (vector->list ...).
1272 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1273 gh_vector_ref, so that it resembles the Scheme routines more.
1274 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1275 resembles the Scheme routines more.
1276 (gh_make_vector): this used to be (stupidly) called gh_vector().
1277 This is the right name, since it does the same thing as the Scheme
1278 (make-vector ...) procedure.
1280 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1282 * ports.h: #include "libguile/print.h"
1284 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
1285 Some indentation fixes.
1287 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1288 longer a user field; New field: class_flags.
1290 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
1292 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
1294 * gh_data.c (gh_bool2scm): new function which replaces
1295 gh_int2scmb(), which is now tagged as obsolete.
1297 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1299 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1300 macros should by convention not test for NIMPness.)
1301 (SCM_COERCE_OPORT): Adjust indentation.
1303 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1304 SCM_NIMP test before SCM_PRINT_STATE_P.
1306 * struct.c, struct.h, gc.c: Renamed:
1307 scm_struct_i_layout --> scm_vtable_index_layout
1308 scm_struct_i_vcell --> scm_vtable_index_vcell
1309 scm_struct_i_vtable --> scm_vtable_index_vtable
1310 scm_struct_i_printer --> scm_vtable_index_printer
1311 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1313 * struct.c (scm_print_struct): Use new printer slot; Default
1314 printing: Also output hex code of vtable so that type identity
1315 will be indicated as well.
1316 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1317 Removed struct_printer_var; Removed struct-vtable-offset;
1318 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1319 vtable-offset-user): New constants.
1321 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1322 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1323 If this slot contains a procedure, use that to print structures of
1324 the type represented by this vtable.
1326 * print.c (scm_iprin1): Don't print arguments of macro
1327 transformers. (They are always: exp env.); Bugfix: Unmemoize
1328 transformer source with correct environment.
1330 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1332 Streamlining of call-with-dynamic-root:
1334 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1335 there is now only one catch.
1336 (cwdr_outer_body): Removed.
1337 (cwdr_handler): New function.
1338 (scm_internal_cwdr): New function to perform the function of cwdr
1339 but take args that are more useful to C code. Also, the handler
1340 is now invoked *outside* of the new dynamic root, like the docs
1341 say. We no longer have to catch absolutely all errors, the caller
1342 is responsible for using a handler that does not throw, if he
1344 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1345 * root.h (scm_internal_cwdr): New prototype.
1347 Even more but risky streamlining:
1349 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1350 allocation of the jumpbuf of a root continuation. The changes
1351 below are controlled by it. They are now deactivated.
1352 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1353 the JMPBUF of the scm_rootcont to NULL before returning.
1355 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1356 when they are non-NULL.
1357 (scm_gc_mark): Likewise, mark only when non-NULL.
1359 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1360 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1362 * gc.c (scm_done_malloc): New function.
1363 gc.h (scm_done_malloc): New prototype.
1365 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
1366 (struct scm_print_state) [revealed]: New field.
1367 (scm_print_state_vtable): Make visible to the outside world for
1368 type checking purposes.
1369 (scm_valid_oport_value_p): New prototype.
1371 * print.c (scm_valid_oport_value_p): New function to check whether
1372 a certain value is acceptable as a port argument.
1373 (scm_print_state_vtable): New variable.
1374 (scm_free_print_state): Set `revealed' field to false.
1375 (scm_iprin1): Call user supplied closure printer with
1376 scm_printer_apply. Print in the traditional way when there isn't
1377 one or when it returns #f.
1378 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1379 Accept a port/print-state pair in addition to just a port.
1380 (scm_prin1): Don't return the print_state to the pool when it has
1382 (scm_printer_apply): Set `revealed' field of print_state to true.
1383 (scm_init_print): Set scm_print_state_vtable.
1384 (print_state_fluid, print_state_fluid_num): Removed.
1386 * throw.h (scm_handle_by_proc_catching_all): New prototype
1387 throw.c (scm_handle_by_proc_catching_all): New function
1389 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1391 * Makefile.in: Regenerated with automake 1.2c.
1393 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1395 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1396 was looping endlessly.
1398 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1400 * strports.c (scm_eval_string): Don't close the port.
1402 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1403 former returns a nice normal integer. (Thanks to Daniel
1406 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1408 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1409 makefile variable as a build parameter called LIBS. The
1410 build-guile program will use this, for the time being.
1411 * Makefile.in: Regenerated.
1413 Thanks to Shiro Kawai:
1414 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1415 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1418 * Makefile.in: Regenerated with automake 1.2a.
1420 * script.c (scm_compile_shell_switches): If we hit the -c or --
1421 arguments, don't set the car of (command-line) to scm_usage_name,
1422 the prettified name of the guile executable; give it the full
1423 path, the way shells usually handle $0.
1425 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1427 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1428 Scheme-level name `array-map' and renamed `serial-array-map' to
1429 `serial-array-map!'.
1431 * backtrace.c: Introduced exception handlers which now enclose
1432 `display-error' and `display-backtrace' so that error reporting
1433 won't get into infinite loops if an error occurs during displaying
1434 of the error. This can very easily happen with user supplied
1435 print call-back routines.
1437 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1439 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1440 the names `serial-array-map' and `array-map' should be removed.)
1442 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1444 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1445 Added #include "objects.h"
1447 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1448 Add #include "feature.h".
1450 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1451 (modinclude_HEADERS): Added objects.h.
1453 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1454 This test is needed at many places in the code and should be
1455 abstracted. (Motivated by the need of this test in libguiletk.)
1457 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1458 (scm_eval_string), load.c (scm_primitive_load,
1459 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1460 Use SCM_EOF_OBJECT_P.
1462 * eval.c (scm_init_eval): Add feature `delay'.
1464 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1466 * scmhob.h: Removed.
1468 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1470 * list.h (SCM_LISTn): New macros. Make list creation in C code
1471 prettier. The idea comes from STk.
1473 * sequences.h, sequences.c, append.h, append.c: Removed. These
1474 files implemented non-R4RS operations which would encourage
1475 non-portable programming style and less easy-to-read code.
1477 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1480 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1481 sequences.h, #include append.h.
1483 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1486 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1488 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1490 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1492 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1494 * eval.c: Added #include "objects.h"
1496 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1499 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1500 adjacent smob numbers.
1502 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1504 * procprop.h: Added declaration of scm_i_inner_name.
1506 * gsubr.c: New global symbol scm_i_inner_name.
1508 * debug.c (scm_procedure_name): Try procedure property
1509 `inner-name' if `name' fails.
1511 * print.c (scm_iprin1): Use scm_macro_name.
1513 * eval.c (scm_m_define): Give names to macros as well; Only the
1514 first top-level definition gives a procedure/macro a name.
1515 Otherwise confusing names can turn up in backtraces.
1516 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1517 `name'; Give names to macros as well.
1519 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1520 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1523 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1525 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1527 (prinmacro): Removed. The code has been moved/merged into print.c
1528 in order to decrease code redundancy. We want macros to print in
1529 a way equivalent to procedures, and it would be silly to duplicate
1530 the required code. (We don't want to maintain two places.)
1531 (macrosmob): Print field is now a NULL pointer.
1533 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1534 scm_macro_transformer): New prototypes.
1535 (scm_tc16_macro): Declared.
1537 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1538 are now printed in a way equivalent to procedures.

1549 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1551 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1552 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1553 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1554 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1555 SCM_BOOL_T. Any non-false value is true.
1557 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1559 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1560 scm_gensym): Added prototypes.

1576 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1578 * Makefile.in: Regenerated.
1580 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1582 * Makefile.in: Regenerated, so it uses "tar", not "gtar".

1586 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1588 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1590 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or

1594 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1595 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1596 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,

1602 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1604 * errno.h: prototype for scm_strerror.
1605 * error.c (scm_strerror): new procedure.
1607 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1609 * list.c (scm_list_append_x): Allow non-pair as last argument.
1610 This is consistent with the R4RS append and is probably the
1611 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1613 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1615 * stime.h: prototype for scm_times.
1616 * stime.c (scm_times): new procedure.

1633 third argument is now optional.
1635 * posix.c (scm_execl, scm_execlp): make the filename argument
1636 compulsory, since omitting it causes SEGV.
1637 (scm_sync): return unspecified instead of #f.
1638 (scm_execle): new procedure.
1639 (environ_list_to_c): new procedure.
1640 (scm_environ): use environ_list_to_c. disable interrupts.
1641 (scm_convert_exec_args): take pos and subr arguments and
1642 improve error checking.
1644 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1646 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1647 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1648 argument to SCM_ASSERT. Furthermore, the name of the function
1649 should be passed as first argument when signalling
1650 SCM_WNA. (Thanks to Thomas Morgan)
1652 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1653 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1654 dispatches on the number of actual args has a default case
1655 reporting an internal error. This is a vestige from a version
1656 that mallocated a SCM vector to hold the arguments. In the
1657 current version this check is too late: if it ever happens we will
1658 have already overstepped the bounds of the array.
1660 Also, the patch [...] adds a check for too many actual arguments."
1662 mdj: Removed check for "internal programming error".
1664 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1666 * gh_io.c (gh_write): New function.
1668 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1669 throw.c (scm_internal_stack_catch): New sibling to the other catch
1670 functions. Code moved from gh_eval.c.
1671 throw.h: Added header.
1672 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1673 scm_internal_stack_catch.

1679 Scheme name is now dup->fdes.
1680 (scm_dup_to_fdes): make the second argument optional and
1681 fold in the functionality of scm_primitive_dup.
1682 (scm_primitive_dup): deleted.
1684 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1686 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1687 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1688 ultrix are defined. Use setvbuf instead of setbuf.
1689 (scm_setvbuf): new procedure.
1690 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1691 (scm_setfileno): moved from ioext.c.

1703 state as nested data while they are printed.
1704 (print_state_fluid, print_state_fluid_num): New variables.
1705 (scm_init_print): Initialize them.
1706 (scm_iprin): If print_state_fluid carries a print_state, use that
1707 instead of creating a new one.
1708 (scm_printer_apply, apply_stub, struct apply_data): New
1709 definitions to help with calling printer functions written in
1711 * print.h (scm_printer_apply): New prototype.

1724 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1725 SCM_ASSERT: arg comes before pos.
1727 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1729 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1730 to a list of length zero correctly.
1732 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

1750 * ioext.c (scm_primitive_dup2): return the new file descriptor
1751 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
1753 (scm_fdopen): bug fix: don't try to make port unbuffered until its
1754 stream has been set.
1755 (scm_duplicate_port): deleted, there's now an implementation in

1808 data. (dynl_smob): Use it.
1809 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
1810 the dynamic object data below the linking of the object to avoid
1811 memory leak when the linking code throws an error. Now the code
1812 leaks a whole dynamically linked library when must_malloc throws,
1813 but that should be much less likely.
1815 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
1817 Changes to compile under gnu-win32, from Marcus Daniels:

1857 * read.c (recsexpr): Give this a dummy definition if
1858 DEBUG_EXTENSIONS isn't #defined.
1860 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
1862 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

1888 turn off REG_EXTENDED.
1889 (scm_init_regex_posix): New regexp/basic symbol.
1890 (REG_BASIC): #define this if it is not already present.

1950 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
1951 the feeling that real thread systems will not need this...
1953 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
1955 Try to detect when people are using one version of libguile and a

1999 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2001 * tag.c (scm_tag): Remove unreachable statement.
2002 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2003 top of the word, it should be unsigned.
2005 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2006 is defined, to avoid warnings; it's only used in the
2007 conflict-checking code. Which might go away anyway.
2008 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2009 conditionals; put the label definition in an #if too, to stifle
2012 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2013 ChangeLog-threads in the distribution.
2014 * Makefile.in: Regenerated.
2016 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2018 * guile-snarf.in: Changed regexp to support CPPs that insert
2019 whitespace between lexical tokens (which munges the `%%%' snarf
2022 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2024 * load.c (scm_init_load_path): Append $(datadir)/guile to
2025 %load-path, so modules do not have to be installed in Guile's
2026 current version directory.
2028 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2030 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2031 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2032 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2033 call the sysdep functions with deferred ints.
2034 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2035 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2036 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2039 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2042 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2044 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2046 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2048 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2051 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2053 * eval.c (scm_lookupcar1): New procedure to cope with a race
2054 condition during lookup (when using threads).
2055 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2056 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2059 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2061 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2062 supplied. (Change from Tim Pierce.)
2064 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2066 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2067 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2068 default and not `()'. `#f' is the canonical non-value in Scheme,
2071 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2073 * struct.c (struct_printer): New variable that holds a handle on
2074 the Scheme variable *struct-printer*. This variable can be set by
2075 Scheme code to override the printing of structures.
2076 (scm_print_struct): If struct_printer is set, call it. If it is
2077 not set, or returns #f, print the structure in the old fashion.
2078 Include "eval.h" for scm_apply.
2080 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2082 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2083 scm_struct_i_n_words to get the number of fields, not
2084 -scm_struct_n_extra_words.
2086 On the route to fancier struct printing:
2087 * struct.c (scm_print_struct): New function to print a structure.
2088 Include "genio.h" to support it. This function doesn't do
2089 anything interesting right now, but I think it should be here
2091 * struct.h: Include "print.h" and add prototype for
2093 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2094 print structures ourself.
2096 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2098 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2099 before applying the handler in case it doesn't return.
2101 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2103 * scmsigs.h, async.h: updated.
2105 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2108 * posix.c (scm_uname): interpret only negative values as an error.
2109 Solaris normally returns a positive value.
2111 * script.c (scm_compile_shell_switches): if we are not going into
2112 an interactive repl, set scm_mask_ints to zero so that asyncs can
2115 * simpos.c (scm_system): don't ignore/unignore signals around
2118 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2121 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2122 done in boot-9.scm instead.
2124 * scmsigs.c, async.c: Major rewriting of signal handling code.
2125 (scm_sigaction): new procedure.
2126 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2128 (scm_raise): return unspecified, throw error on failure.
2130 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2132 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2133 feature, to help boot-9.scm decide whether to import the regex
2136 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2138 * eval.c: Include scmconfig.h at the beginning of the file so that
2139 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2142 * regex-posix.c: #include "_scm.h" before conditionally #including
2143 <regex.h>; the former defines HAVE_REGCOMP.
2145 * regex-posix.c: #include <regex.h> conditionally, so the file is
2146 CPP'able (for dependency scanning) even on systems that don't have
2149 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2151 Add new R4RS-compliant syntax for keywords.
2152 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2153 regardless of the setting of the `keywords' read option.
2154 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2155 can be re-read no matter what the setting of the `keywords' read
2158 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2160 Add support for POSIX regular expressions.
2162 * regex-posix.c, regex-posix.h: New files. (Some code
2163 is taken liberally from rx/rgx.c in the old Guile dist.)
2165 * init.c: Include regex-posix.h.
2166 (scm_boot_guile_1): Call scm_init_regex_posix.
2168 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2169 Add regex-posix.[ch] sources.
2170 * Makefile.in: Regenerated.
2172 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2173 to do this automatically? It didn't for me, bleh.)
2175 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2177 * fports.c (print_pipe_port): New function.
2178 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2179 latter doesn't even take the right arguments.
2181 * Makefile.am: Increment shared lib revision number. I think
2182 sometimes the uninstalled Guile finds the installed shared lib;
2183 Gord says doing this might help. As things turned out, I can't
2184 say whether it does.
2185 * Makefile.in: Regenerated.
2187 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2188 passing it as the closure argument to scm_boot_guile. (Bill
2191 * ports.c (print_void_port, putc_void_port, puts_void_port,
2192 write_void_port, flush_void_port, getc_void_port, close_void_port,
2193 noop0): Use ANSI prototypes instead of K&R declarations, so the
2194 initialization of void_port_ptob gets aggressively type-checked.
2195 Fix arguments of print_void_port and write_void_port. (Bill

2229 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2231 * script.c (scm_find_executable): Use prototype-style definition
2232 here; apparently it's not quite right to have const in a prototype
2233 and then use a K&R declaration. I wonder if stuff like this will
2234 go away if we compile with -Wrequire-prototypes, or whatever that
2235 is... (Bernard URBAN)
2237 * scmhob.h: New text from Bernard URBAN.
2239 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2241 * script.c: Don't #define const on hpux. Configure takes care of
2242 this. (Thanks to Larry Schwimmer.)
2244 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2245 decide whether to #include <unistd.h>, instead of listing a bunch
2246 of systems. Don't #include stdio twice. Removed dyked-out
2247 definition of scm_find_impl_file.
2249 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2251 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2252 library version info to 1:0.
2253 * Makefile.in: Regenerated.
2255 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

2259 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2260 throw.c: Update copyright years; these files have been worked on
2261 significantly in 1997, but only had copyright years for 1996.
2262 Also, change name of copyright holder on some from Mikael
2263 Djurfeldt to Free Software Foundation; he has signed papers
2264 assigning the changes to the FSF.
2266 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2267 reason not to give the user the option.
2269 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2270 Return #f on end-of-file when scanning table (i.e. when called
2271 with no arguments). Try to catch errors, when we can.
2272 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2274 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2275 external declarations. These are useful.
2277 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2279 * posix.c: don't include <sys/select.h> or define macros for
2280 select, since they were not used in this file.
2282 * filesys.c (scm_select): make the fifth parameter microseconds,
2283 not milliseconds. let the fourth parameter be either a real value
2284 or an integer or #f. The first, second and third arguments can
2285 now be vectors: the type of the corresponding return set will be
2287 (set_element, get_element): new static procedures.
2289 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2291 * strports.c (scm_eval_string): New function.
2292 (scm_eval_0str): Trivially re-implemented in terms of
2294 * strports.h (scm_eval_string): New extern decl.
2296 * net_db.c (h_errno): Add extern decl for this.
2298 * fports.c (local_pclose): New function.
2299 (scm_pipob): Use it in the initializer here.
2302 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2303 Use a meaningful error message when signalling an error. For
2304 this, scm_gethost must check h_errno rather than errno.
2306 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2308 * Makefile.in: Regenerated, using automake-1.1p.
2310 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2312 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2313 not SCM_UNSPECIFIED.
2315 * script.c (scm_compile_shell_switches): don't append (quit) if
2317 (scm_shell): call scm_exit_status and exit on the result of the
2320 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2322 Ensure that shared substrings are handled properly when passed to
2323 a system call or other foreign function. Many thanks to Tim
2325 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2326 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2327 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2328 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2330 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2331 (scm_display_error_message): use RO macros when strings may be RO.
2332 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2333 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2334 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

2339 scm_strftime), vports.c (scm_make_soft_port): use
2340 SCM_COERCE_SUBSTR to make sure shared substrings are
2343 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2345 * error.c (scm_error): Add newline to error message.
2347 * init.c (scm_init_standard_ports): Doc fix.
2349 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2351 * dynl-shl.c: Completely replaced with new code from Bernard
2354 * script.c (scm_ice_9_already_loaded): New variable.
2355 (scm_compile_shell_switches): Use it.
2357 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2359 * filesys.c (scm_input_waiting_p): add missing third argument to
2362 * stime.c (scm_localtime): copy the result of localtime before
2363 calling gmtime in case they share a buffer.
2364 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2367 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2369 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2371 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2373 * Makefile.am (check-local): New target, which causes 'make check'
2374 to run gh_test_c and gh_test_repl, with some trivial input.
2375 * Makefile.in: Rgnrtd.
2377 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2379 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2382 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2384 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2385 sure how this was supposed to work.
2386 (scm_async_click): don't send SCM_TICK_SIGNAL.
2387 (scm_init_async): don't initialize %tick-thunk.
2389 * the following change doesn't affect the Scheme interface:
2390 gc-thunk is called at the end of garbage collection. however it's
2391 no longer implemented by pretending it's a signal.
2393 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2394 system async corresponding to scm_gc_thunk.
2395 * async.h: declare scm_gc_async.
2396 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2397 gc-thunk directly, instead of going through a signal handler.
2398 (scm_gc_async): new variable, points to the GC system-async.
2399 (scm_init_async): save the GC async as scm_gc_async instead
2400 of using system_signal_asyncs.
2401 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2403 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2405 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2406 Don't screw up if we're interrupted.
2407 * Makefile.in: Regeneradet.
2409 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2411 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2413 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2414 we're not using AM_INIT_GUILE_MODULE any more.
2415 * Makefile.in: Reneregated.
2417 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2419 Functions for finding variable bindings, grace à Tim Pierce.
2420 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2421 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2423 Get 'make dist' to work again.
2424 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2425 * Makefile.in: Regenerated, like a surry without a fringe on top.
2427 Changes for reduced Guile distribution: one configure script,
2429 * configure.in, configure: Removed.
2430 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2431 real configure script lives.
2432 * Makefile.in, scmconfig.h.in: Regenerated.
2434 * init.c: #include "script.h", to get prototype for script.c's
2437 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2439 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2440 scm_must_malloc, not raw malloc.
2442 * script.c (scm_compile_shell_switches): Dyke out debugging output
2445 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2447 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2449 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2450 system has them. Hope this is safe. Previously
2451 sys/timeb.h was included if HAVE_FTIME was defined or if
2452 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2453 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2455 * ioext.c (scm_setfileno): add missing third argument to
2456 scm_misc_error call.
2458 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2460 * eq.c (scm_equal_p): Correctly compare strings of different
2461 varieties. (Thanks to Tim Pierce.)
2463 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2465 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2466 #! block comment must occur on a line all by itself.
2468 Move most of the guts of shell command processing into libguile,
2469 so guile.c can be very small (and eventuallly auto-generated. (I
2470 mean, generated mechanically, not self-generated. Hmm.))
2471 * guile.c, script.c, script.h: New source files.
2472 * init.c (scm_boot_guile_1): Call scm_init_script.
2473 * libguile.h: #include "script.h".
2474 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2475 targets, for new executable.
2476 (libguile_la_SOURCES): Mention script.c.
2477 (modinclude_HEADERS): Add script.h.
2478 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2479 not dynamic linking is enabled. This is because we're generating
2480 executables now. Move CY_AC_WITH_THREADS call after those, so the
2481 values of cy_cv_threads_libs captures the libs chosen above.
2482 * Makefile.in, configure, aclocal.m4: Regenerated.
2484 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2485 We don't maintain this interface any more, and it just confuses
2488 * alloca.c: #include <scmconfig.h>, not <config.h>.
2489 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2490 it'll get included in disties.
2492 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2494 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2495 be distributed, because they confuse people.
2496 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2498 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>

2501 OpenBSD by default).
2502 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2503 * configure, scmconfig.h.in: Regenerated.
2505 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2507 * backtrace.c (scm_backtrace): Split message string across
2508 newlines properly. GCC is more tolerant of this than other

2513 Merge threads directory into libguile.
2514 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2515 threads.h: New source files.
2516 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
2517 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2519 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2520 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2521 coop-threads.c.cygnus, coop-threads.h.cygnus.
2522 * configure.in: If we're using threads, include threads.o in
2524 * _scm.h, libguile.h: threads.h lives in this directory now.
2525 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2526 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2527 currently used, but brought along for information's sake.
2528 * ChangeLog-threads: log from old 'threads' directory.
2529 * Makefile.in, configure: Rebuilt.
2531 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2533 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2536 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2538 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2540 Merge GH interface library into libguile.
2541 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2542 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2543 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2544 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2546 (EXTRA_libguile_la_SOURCES): ... here.
2547 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2548 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2549 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2550 New variables, describing how to build the gh test programs.
2551 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2552 build the test programs, and we probably should have been linking
2553 libguile.la against them all along, to support AIX shared libs.
2554 Add cflags for threads to CFLAGS; add libs for threads to new
2555 variable THREAD_LIBS, used in Makefile.am.
2556 * ChangeLog-gh: log from old `gh' subdirectory.
2557 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2559 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2561 * acconfig.h: Undo change of Apr 9; including the definition of
2562 PACKAGE in the guile headers conflicts with applications' own
2564 * scmconfig.h.in: Regenerated.
2566 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

2573 when PROC is receiving no arguments.
2575 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2577 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2578 have S_IFSOCK. This is the case under Ultrix.
2580 * posix.c (scm_status_exit_val, scm_status_exit_val,
2581 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2582 Ultrix versions of WIFSTOPPED, etc., which assume that their
2583 arguments are lvalues (hmm).
2585 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2587 * eval.c: Doc fixes.
2589 * throw.c: Doc fixes; rearranged.
2591 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
2593 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
2595 * acconfig.h: Added entry for PACKAGE.
2596 * scmconfig.h.in: Regenerated.
2598 Changes to work with automake-1.1n, which has better libtool support.
2599 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2600 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2602 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2604 * Makefile.in: Rebuild.
2606 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2608 * stime.c (scm_mktime): take an optional zone argument.
2609 (scm_localtime): check putenv return value.
2610 (scm_strftime, scm_strptime): moved from posix.c. move #include
2612 stime.h, posix.h: update prototypes.
2613 (bdtime2c, setzone, restorezone): new static procedures.
2614 (scm_mktime, scm_strftime): use them.
2615 (scm_strftime): don't call mktime before strftime. Use
2616 filltime for return value.
2617 (filltime): convert NULL zname to #f.
2618 (scm_strptime): return a count of characters consumed, not
2619 the remaining string.
2621 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2623 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2624 (scm_mktime): likewise.
2626 Uncomment localtime and mktime.
2628 * configure.in: add AC_STRUCT_TIMEZONE.
2630 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2632 * stime.c (scm_init_stime): don't define ticks/sec.
2633 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2634 return value problem and is still portable.)
2636 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2638 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2639 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2640 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2641 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2642 cpp_err_symbols.c): Corresponding changes.
2643 * Makefile.in: Regenerated.
2645 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2647 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2648 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2649 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2650 * putenv.c: new file, from sh-utils 1.12.
2652 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2653 since allocation isn't for Scheme objects.
2654 (scm_putenv): copy strings before placing in the environment.
2656 * stime.c (scm_current_time): throw an error if time returns -1,
2657 instead of returning #f.
2658 (scm_get_internal_real_time, scm_get_internal_real_time): use
2659 scm_long2num for return value instead of SCM_MAKINUM.
2661 * stime.h: prototypes updated.
2663 * stime.c (scm_time_in_msec): apparently unused, deleted.
2665 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2667 * configure.in: check for gettimeofday.
2669 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2670 which may be more usefully portable than a gettimeofday interface.
2672 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2674 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
2676 * Makefile.in: Regenerated.
2678 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2680 * stime.c (filltime): recovered static procedure.
2681 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2684 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2685 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2687 * posix.c (scm_mknod): split the mode argument into type and perms
2688 arguments, like the extra fields returned by stat.
2690 * fports.c (scm_pipob): set the close, free and print procedures.
2691 (scm_close_pipe): new procedure.
2693 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2694 define them in boot-9.scm
2696 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2698 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2699 wan't defined. Don't include fd.h.
2701 * Previously fd.h was regenerated whenever configure was run,
2702 forcing a couple of files to be recompiled.
2704 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2705 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2706 Check for _fileno as well as _file.
2708 * ioext.c: don't fd.h.
2709 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2712 * Change the stratigy for getting information about errno
2713 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2714 generating lists of symbols during the build process, which will
2715 not always work, include comprehensive lists in the distribution.
2716 To help keep the lists up to date, the "check_signals" and
2717 "check_errnos" make targets can be used.
2719 * configure.in: don't check for a command to extract errno codes.
2720 * Makefile.am: update file lists, remove errnos.list and errnos.c
2721 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2722 check_errnos targets.
2723 (CLEANFILES): remove errnos.c and errnos.list, add
2724 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2725 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2726 * errnos.default: deleted.
2727 * cpp_signal.c: new file.
2728 * cpp_errno.c: renamed from errnos_get.c.
2729 * cpp_err_symbols, cpp_sig_symbols: new files.
2730 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2731 * error.c (scm_init_error): #include cpp_err_symbols instead of
2733 * posix.c (scm_init_posix): don't intern signal symbols. #include
2736 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2738 * strop.c (scm_i_index): allow the lower bound to be equal to the
2739 length of the string, so a null string doesn't always give an error.
2741 * posix.h: new prototypes.
2742 * posix.c (scm_status_exit_val, scm_status_term_sig,
2743 scm_status_stop_sig): new functions, as in scsh. They break down
2744 process status values as returned by waitpid.
2746 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2748 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2749 configure doesn't know about it.
2751 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2753 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2755 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2756 which defines C variables with global linkage.
2758 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2760 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2763 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2765 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2766 has time to check why this doesn't work well with continuations.
2768 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2770 * Fix shell syntax error; some shells won't tolerate
2771 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2773 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2775 * posix.c (scm_uname): throw an error if uname fails instead
2778 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
2780 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
2783 * async.c (scm_ints_disabled): definition moved from error.c.
2785 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2787 * acconfig.h: Removed PACKAGE.
2789 * scmconfig.h.in: Regenerated.
2791 * snarf.h: g++ says it's non-portable not to specify the first
2792 argument in a varargs declaration. I introduced the first
2793 argument by using preprocessor conditionals.
2795 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
2797 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
2798 (scm_freopen): use RO string macros for filename and modes.
2799 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
2801 * posix.c (scm_getgrgid): simplify conversion of name to C string.
2802 (scm_mknod): use RO string macros for path.
2804 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
2805 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
2807 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2808 use SCM_ROSTRINGP and SCM_ROCHARS.
2810 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2812 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
2815 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
2816 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
2817 support for byte vectors.
2819 * print.c (scm_iprin1): Limit number of vector elements printed
2820 according to pstate->length.
2822 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2824 * backtrace.c (scm_display_error_message): don't segv if message
2827 * error.h: prototype for scm_error_scm.
2829 * error.c (scm_error_scm): new procedure, reimplements scm-error
2830 in C and uses scm_error.
2832 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2834 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
2835 pointer to the Scheme variable read-hash-procedures and intern it
2836 in scm_init_read. Modify scm_read_hash_extend and
2837 scm_get_hash_procedure to use the pointer.
2839 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2841 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
2842 (SCM_KEYWORD_STYLE): defined.
2844 * read.c (scm_read_opts): add a keywords option. This isn't a
2845 boolean option, in case someone wants to add support for DSSSL
2847 Setup scm_keyword_prefix symbol.
2848 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
2850 I've left keyword support disabled by default, since it doesn't
2851 seem to break the module system and it gives R4RS standard behaviour.
2852 It can be reactivated with (read-set! keywords 'prefix).
2854 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2856 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
2857 before constructing arbiter.
2859 * eval.c (scm_m_define): Bugfix: Check that the object is a
2860 closure before setting the procedure property!
2862 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
2864 * ports.c: Removed `ungetc-char-ready?'.
2866 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
2868 * read.c (scm_init_read): intitialise scm_read_hash_procedures
2869 (idea from Mikael: make it a pair so scm_permanent object only
2871 (scm_read_hash_extend): don't call scm_permanent_object.
2872 (ideas from Mikael): if chr is already in the list, replace its
2873 procedure instead of appending it again. If proc is #f, remove
2875 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
2877 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
2879 * gdbint.c (gdb_read): update scm_lreadr usage.
2881 * load.h: update prototypes.
2883 * load.c (scm_primitive_load, scm_read_and_eval_x,
2884 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
2886 * read.h: add prototype for scm_read_hash_extend. Change args for
2889 * read.c (scm_read_hash_procedures): new variable.
2890 (scm_read_hash_extend): new procedure.
2891 (scm_get_hash_procedure): new procedure.
2892 (scm_lreadr): use scm_get_hash_procedure instead of an argument
2893 for extended # processing.
2894 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
2895 scm_read_token): remove case_i, sharp arguments. Change callers.
2897 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
2899 * read.h (SCM_N_READ_OPTIONS): increase to 3.
2900 (SCM_CASE_INSENSITIVE_P): define.
2902 * read.c: add case-insensitive option to scm_read_opts.
2903 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
2904 to determine whether to convert symbol case.
2905 (default_case_i): definition removed.
2906 * read.c (scm_read_token): if case_i, downcase ic before doing
2909 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2911 * configure.in: Added configuration option `guile-debug'.
2912 Configure with --enable-guile-debug if you want a bunch of extra
2913 functions used for debugging when developing Guile.
2915 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
2917 * procs.c (make-cclo): New undocumented debugging procedure: Make
2918 compiled closure with internal procedure PROC and length LENGTH.
2919 Only compiled if GUILE_DEBUG is defined.
2921 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
2923 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
2925 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
2927 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
2928 with 3 or more args internally to the evaluator.
2930 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2932 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
2933 with 3 or more args internally to the evaluator. This is mainly
2934 because we don't want to pass entry and exit points of the
2935 debug support twice, but it also seems to increase the speed of
2936 the evaluator for such calls (e. g. (+ 1 2 3)).
2938 * backtrace.c (scm_display_application): New procedure:
2939 display-application; Set fancy printing parameters individually
2940 for different types of display (backtrace, error, application).
2941 (These should of course be customizable!)
2943 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
2944 clear the CHECK-flags.
2946 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2948 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
2950 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2952 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
2953 from pairs with a GLOC in the car.
2955 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
2956 otherwise `symbol-hash' will behave badly.
2957 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
2958 we get segmentation fault!
2960 * symbols.c: Added #include "weaks.h". New functions:
2961 `builtin-bindings' and `builtin-weak-bindings'. (These will be
2962 moved to an extraneous library when we split libguile.)
2964 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2966 * filesys.c (scm_stat): stat now takes fport arguments too as
2967 documented in the manual.
2969 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2971 * debug.c (scm_single_step): Bugfix: Call continuation with
2972 scm_call_continuation instead of throwing to it.
2974 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
2976 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
2977 argument wasn't declared to be optional.
2979 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2981 * stime.c (scm_init_stime): Add feature "current-time".
2983 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2985 * throw.h: prototype for scm_exit_status.
2986 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
2987 args to derive an exit status. Allows (quit) to work from a
2989 (scm_exit_status): new function.
2992 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2994 * eval.c (scm_deval): Removed some old code.
2995 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
2997 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3000 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3003 * procs.c: Introduce the existent C function scm_thunk_p at the
3004 Scheme level as well.
3006 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3008 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3009 used from C to easily lookup the value of a symbol in the current
3012 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3014 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3015 scm_init_unif in this file. This will also fix a previous problem
3018 * configure.in: Added AM_MAINTAINER_MODE
3020 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3022 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3025 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3027 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3028 source files that are not always included in libguile but should
3029 have their dependencies calculated by automake. This variable is
3030 recognized by automake, no further magic is needed.
3031 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3032 to deal exclusively with *.lo files, as it seems. The *.o files
3033 are built automatically when the corresponding *.lo file gets
3036 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3038 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3041 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3043 * unif.c (scm_array_set_x): minor change to argument error checking.
3045 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3047 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3048 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3049 They should only be included in the library at configure.in's
3051 (libguile_la_LDADD): Include the appropriate .lo files here.
3052 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3053 so we know when to build them (and their .lo bretheren).
3054 * configure.in (LIBLOBJS): New substituted variable. We let
3055 configure decide which .o files to include in LIBOBJS, and then
3056 put the corresponding list of .lo files in LIBLOBJS. The latter
3057 is what we pass to libtool.
3058 * Makefile.in, configure: regenerated.
3060 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3062 * symbols.c (scm_sysintern0): New function. Contains the core of
3063 old scm_sysintern but doesn't take a second value argument.
3064 (scm_sysintern): Now uses scm_sysintern0.
3065 (scm_sysintern_no_module_lookup): Renamed to
3066 scm_sysintern0_no_module_lookup and doesn't take a second value
3067 argument any longer.
3069 * symbols.h (scm_sysintern0: Added declaration.
3071 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3072 scm_sysintern when interning option keys. Otherwise we risk
3073 destroying the values of already interned variables.
3075 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3076 scheme-level boolean (use SCM_NFALSEP).
3078 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3080 (scm_backtrace): New function. (C version of old function from
3081 boot-9.scm) Motivation: Make it possible to display backtraces
3082 without depending on boot-9.scm. (I'm uncertain if this
3083 motivation is good enough...)
3085 * root.h (scm_root_state): Add member the_last_stack_var.
3086 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3088 * root.c (mark_root): Mark scm_the_last_stack_var.
3090 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3093 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3095 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3096 1. mark_lazy_catch didn't mark the smob.
3097 2. Both functions above have standard variants:
3098 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3099 free_lazy_catch --> scm_free0.
3101 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3103 * throw.c (scm_internal_lazy_catch): New function.
3104 (scm_lazy_catch): Rewritten to use it.
3105 (scm_ithrow): Handle the new lazy catch representation.
3106 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3107 that doesn't have a jmpbuf is a lazy catch clause.
3108 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3109 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3110 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3112 (scm_init_throw): Register the new lazy-catch smob type.
3113 * throw.h (scm_internal_lazy_catch): decl for new function.
3115 * throw.c (scm_internal_catch): Doc fixes.
3117 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3118 configure.in. Including this might cause problems if applications
3119 that link against libguile include their own copies of alloca, but
3120 if they're using autoconf, they should be adding libguile to LIBS
3121 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3122 the copy in libguile, and things will be okay. (I think.)
3124 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3126 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3128 strop.h: move prototypes too.
3130 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3132 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3135 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3136 etc. I deleted them from filesys.c long ago, but didn't
3137 notice they were here too (although ineffective since
3138 sys/stat.h wasn't included).
3140 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3142 * eval.c: Don't define alloca in GCC case. gcc will automatically
3143 use __builtin_alloca if appropriate.
3145 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3147 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3148 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3149 that values of automatic variables are preserved. See comments
3150 for safe_setjmp for details.
3152 Change from Thomas Morgan:
3153 * variable.c: Include eq.h.
3154 (var_equal): New function.
3155 (variable_smob): Use var_equal as the discriminator for variables.
3157 * throw.c (s_throw): Remove extraneous declaration.
3159 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3160 * eval.c: Add necessary CPP cruft to support that.
3161 * configure, Makefile.in, scmconfig.h.in: regenerated.
3163 Change from Thomas Morgan:
3164 * procprop.c (scm_procedure_properties): Convert the Scheme
3165 boolean returned by scm_procedure_p into a C boolean before using
3166 it as a condition for SCM_ASSERT.
3167 (scm_procedure_property): Likewise.
3169 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3170 indications of Unixness.
3173 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3175 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3177 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3179 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3180 "unknown # object" error messages.
3182 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3183 (scm_i_index) and declare it static. Add a 'direction' argument
3184 to indicate what way the search should go.
3185 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3187 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3188 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3190 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3192 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3194 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3195 to avoid clash with various scsh forks.
3197 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3199 The following two changes (ramap.c, throw.c) are motivated by the
3200 apparent unportability of forward declarations of static arrays of
3201 the form `static foo bar[];'.
3203 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3204 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3206 * throw.c (scm_throw): Moved above scm_ithrow.
3208 * options.h: Removed the extern declarations of scm_yes_sym and
3209 scm_no_sym since these are static.
3211 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3213 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3215 * Makefile.am: remove AWK=@AWK@.
3216 Add a rule for generating errnos.list.
3217 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3219 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3220 don't extract errnos, just set a variable (avoids the
3221 need to recompile error.c just because configure is run.)
3223 * unif.h: update prototypes.
3224 * unif.c (scm_uniform_array_read,write): change the offset and
3225 length arguments to start and end, for consistency.
3227 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3229 * ioext.h: update prototypes.
3230 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3231 scm_read_line_x, it's a more general procedure using an
3232 interface from scsh. read-line and read-line! are now defined
3234 Note that the new read-line trims the terminator
3235 by default, previously it was appended to the returned string. An
3236 optional argument specifies how to process the terminator (scsh
3237 compatible). For the old behaviour: (read-line port 'concat).
3238 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3239 returns a pair, but is converted to multiple values if the scsh
3242 socket.h: update prototypes.
3243 * socket.c (scm_recvfrom): for consistency with other procedures,
3244 take start and end as separate optional arguments.
3245 (scm_recv, scm_recvfrom): don't allow the second argument
3246 to be a size, only a buffer. Change the scheme names to
3247 recv! and recvfrom!. Don't return the buffer.
3249 * ioext.h, posix.h: move prototypes too.
3250 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3251 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3252 "read.h" and "unif.h".
3253 * ioext.c: include "chars.h"
3255 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3257 * dynl.c: The dynamic linking and module registration functions
3258 are now defined even when dynamic linking is not available for the
3259 host system. Some of their functionality can be done without
3260 dynamic linking; when it's really needed, they throw errors.
3262 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3264 * configure.in: Only define DYNAMIC_LINKING when one of the system
3265 dependent functions is detected.
3266 * dynl.c (scm_dynamic_func): New function to get the address of a
3267 function in a dynamic object.
3268 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3269 produced by scm_dynamic_func as the thing to call.
3271 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3273 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3274 (scm_register_module_xxx, scm_registered_modules,
3275 scm_clear_registered_modules): New functions.
3277 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3279 * symbols.c (scm_sysintern): Renamed to
3280 scm_sysintern_no_module_lookup.
3281 (scm_sysintern): New function to take the place of the old
3282 scm_sysintern. It uses the current toplevel lookup closure to give
3283 the symbol its value. This is a temporary hack to put packages
3284 like gtcltk into their own module.
3285 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3286 us whether `scm_top_level_lookup_closure_var' has been initialized
3288 * eval.c (scm_init_eval): Set it.
3290 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3292 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3293 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3295 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3297 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3298 scm_sys_dup): deleted: FD capability will be added to other
3300 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3301 scm_fd_free, fd_smob, scm_intern_fd.
3302 (scm_open): renamed from scm_sys_open. Return a port instead of
3303 an FD object. Make the mode argument optional.
3304 (scm_sys_create): deleted, it's just a special case of open.
3305 (scm_init_filesys): move interning of constants O_CREAT etc.,
3306 here (were previously using SCM_CONST_LONG macro).
3307 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3309 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3310 include "fports.h" and <stdio.h>
3311 (scm_stat, scm_select): don't support FD objects.
3313 * error.h: adjust scm_syserror_msg prototype.
3314 * error.c (scm_syserror_msg): take an extra argument for errno.
3315 Using the global value didn't always work, since it could be
3316 reset by procedure calls in the message or args arguments.
3318 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3319 I don't understand why the check was there (and what about the
3322 * strop.c (scm_string_copy): allow shared substrings to be copied.
3324 * unif.h: corresponding change to prototypes.
3325 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3326 recognize two new optional arguments: offset and length. Allow
3327 the port argument to be an integer (file descriptor, for scsh).
3328 Include <unistd.h> for "read" prototype.
3330 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3332 * socket.c: don't include filesys.h.
3334 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3336 * Makefile.am: add AWK=@AWK@ (?)
3338 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3340 Add a rule to generate errnos.c from errnos.
3341 * error.c (scm_init_error): include errnos.c.
3342 * errnos_cnvt.awk: new file, converts the list of errno codes to
3344 * errnos_get.c: new file.
3345 * errnos.default: new file, contains errnos to try if they can't
3346 be extracted from errno.h.
3347 * configure.in: if using GCC, try and extract errno codes from
3351 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3353 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3354 * Makefile.am: Made libguile into a libtool library.
3355 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3356 Set libtool_libs to indicate that libguile is a libtool library.
3357 See guile/ChangeLog for details.
3358 * .cvsignore: ignore "*.lo", the libtool library objects.
3360 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3362 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3363 use htons in getservbyport argument.
3365 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3367 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3368 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3371 * objprop.c (scm_object_property): No need to take the CDR of the
3372 value returned by scm_object_properties, since Aug 20 change.
3374 * configure.in: When checking for struct linger, #include
3375 <sys/types.h> as well as <sys/socket.h>. I've never known
3376 <sys/types.h> to cause any portability problems, and Solaris's
3377 <sys/socket.h> needs it.
3378 * configure: Rebuilt.
3380 I think the Sun compiler has chosen a perverse way to interpret
3381 ANSI declarations combined with K&R definitions. We'll
3382 appease it a little bit. But when it invades France, we fight.
3383 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3384 * print.h (scm_iprlist): Here too.
3385 * numbers.c (scm_divbigdig): Change definition to match
3386 declaration in numbers.h.
3387 * unif.c (scm_makflo): Change definition to match declaration in
3390 * init.c (scm_boot_guile): Don't return the value of
3391 scm_boot_guile_1. This function doesn't return a value;
3392 scm_boot_guile_1 doesn't return a value (or return at all).
3394 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3397 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3398 compile. I have a feeling this function is a bad idea anyway ---
3399 one should always test for features, not systems.
3401 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3402 semicolons. Only pure luck kept this from being noticed earlier.
3404 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3406 * socket.c (scm_recvfrom): Added missing semicolon.
3408 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3410 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3411 the buffer and start and end positions for scsh networking
3414 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3416 * configure.in: Revert previous change to this file; the problem
3417 is due to transient automake weirdness.
3418 * configure: Rebuilt.
3420 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3421 PLUGIN/guile.libs. configure generates the latter from the former.
3422 * Makefile.in: Rebuilt.
3424 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3425 need this if we install scripts, like guile-snarf.
3426 * configure: Rebuilt.
3428 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3430 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3432 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3434 * socket.c (scm_addr_vector): fix faulty scm_listify.
3436 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3438 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3439 style block comment is no longer considered an error.
3441 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3443 * PLUGIN/guile.libs.in: New file.
3444 * PLUGIN/guile.libs: Removed from repository.
3445 * configure.in: Create PLUGIN/guile.libs from
3446 PLUGIN/guile.libs.in. This is for including additonal libraries
3447 needed for dynamic linking.
3448 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3449 instead of PLUGIN/guile.libs.
3451 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3453 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3455 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3456 occurrences of the given element from the list, not just the
3457 first. This is how the Emacs Lisp functions behave, how the
3458 analogous Common Lisp functions behave, and (I believe) how the
3459 older Maclisp functions worked. I realize that this change may
3460 break code, but it seemed better to break it before the Guile
3463 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3464 Their prototypes were already present in gc.h, but they weren't
3466 (scm_init_storage): Initialize scm_protects.
3467 * root.c (scm_protects): New element of scm_sys_protects.
3469 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3471 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3473 * libguile.h: Added #include "libguile/net_db.h".
3475 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3476 30 change. That file is only meant for communication between the
3477 configuration process and load.c. If code linked against libguile
3478 wants to get at the paths mentioned in libpath.h, it can call
3479 functions declared in load.h.
3481 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3483 * libguile.h: Removed #include "libguile/fdsocket.h"
3485 * net_db.c: Added #include <sys/socket.h>.
3487 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3489 * filesys.c (scm_input_waiting_p): use select in preference to
3490 FIONREAD, since the latter doesn't detect EOF.
3491 Throw error if neither select nor FIONREAD available.
3493 * socket.c (scm_connect): take a port, not a fd object.
3494 (scm_fill_sockaddr): throw an error if fam is not recognised.
3495 (scm_bind): use scm_fill_sockaddr.
3496 (scm_listen): take a port, not a fd object.
3497 (scm_accept): take and return a port. return #f in the car if
3498 address can't be got
3499 (scm_sock_fd_to_port): new procedure.
3500 (scm_socket): use scm_sock_fd_to_port.
3501 (scm_addr_vector): throw error if unrecognised address type.
3502 take an extra argument with the calling procedure name.
3503 (scm_getsockname): take a port. return #f if address can't be got.
3504 (scm_getpeername): take a port. return #f if address can't be got.
3505 (scm_recvfrom): take a port. return #f for address component if can't
3507 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3508 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3510 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3512 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3513 use separate data pointers, to allow them to be designed
3514 independently and reused.
3515 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3516 Renamed from catch_body, catch_handler, and uncaught_throw; made
3518 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3520 (scm_catch): Use the above.
3521 (scm_throw): Don't bother printing a message for an uncaught
3522 throw; we establish a default handler in init.
3523 * throw.h (scm_internal_catch): Prototype updated.
3524 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3526 (struct scm_body_thunk_data): New structure, used as data
3527 argument to scm_body_thunk.
3528 * init.c (struct main_func_closure): New structure, packaging up
3529 the data to pass to the user's main function.
3530 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3531 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3532 scm_internal_catch to establish a catch-all handler, using
3533 scm_handle_by_message. This replaces the special-case code in
3535 (invoke_main_func): Body function for scm_internal_catch; invoke
3536 the user's main function, using the main_func_closure pointer to
3537 decide what to pass it.
3538 * root.c (struct cwdr_body_data): Remove handler_proc member.
3539 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3540 (cwdr_handler): Removed.
3542 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3544 * socket.h (SCM_P): update bind prototype.
3545 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3546 include "feature.h".
3547 (scm_socket): return a port, not a file descriptor object.
3548 include "fports.h" and <unistd.h>
3549 (scm_bind): take a port, not a file descriptor object.
3550 take an extra argument for address args.
3552 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3553 INADDR_NONE, INADDR_LOOPBACK.
3555 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3557 * init.c: include net_db.h and not fdsocket.h.
3558 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3560 * Makefile.am: corresponding changes.
3561 * socket.h: renamed from fdsocket.h, fix names.
3562 * net_db.h: renamed from socket.h, fix names.
3563 * socket.c: renamed from fdsocket.c.
3564 remove _sys from procedure names.
3565 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3566 add "socket" to features list.
3567 * net_db.c: renamed from socket.c.
3568 remove _sys from procedure names.
3569 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3570 add "net-db" to features list.
3571 include "net_db.h". don't include <sys/socket.h> or
3574 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3576 * tags.h (scm_tags): Removed comma at end of last enumerator.
3578 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3580 Don't use GCC extensions to allocate space for debugging frames.
3581 (Here he goes again! Why do we put up with this?!)
3582 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3583 an scm_debug_info structure, not an in-line array of them. Add
3584 'info' member, to say how many vect elements we've used, for eval
3586 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3587 a new variable debug_info_end to mark the end of vect, instead of
3588 the address of the 'info' pointer itself.
3589 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3590 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3591 (SCM_APPLY): Explicitly allocate space for debug.vect.
3592 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3593 * stacks.c: Adjusted for new debug frame structure.
3594 (RELOC_INFO, RELOC_FRAME): New macros.
3595 (stack_depth, read_frames): Use them, and new scm_debug_frame
3596 element 'info', instead of magically knowing that eval frames have
3597 an info pointer sitting after vect.
3598 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3600 (scm_init_stacks): Formatting tweaks.
3602 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3604 Give GCC more control flow information, so it can be sure that
3605 variables aren't used uninitialized.
3606 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3607 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3608 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3609 scm_misc_error): Tell GCC that these functions never return.
3610 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3611 out the field type, call abort if SCM_ASSERT returns, to placate
3613 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3614 scm_wta ever returns. We can't handle this case anyway, and this
3615 gives the optimizer more information.
3616 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3617 scm_wta ever returns.
3619 In some cases, the code is fine, but GCC isn't smart enough to
3620 figure that out; this usually happens when one variable is only
3621 initialized and used when a particular condition holds true, and
3622 we know that condition will never change within a given invocation
3623 of the function. In this case, we simply initialize the variables
3624 to placate the compiler, hopefully to a value which will cause a
3625 crash if it is ever actually used.
3626 * print.c (scm_iprin1): Initialize mw_pos.
3627 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3628 * throw.c (scm_ithrow): Initialize dynpair.
3629 * unif.c (scm_uniform_vector_ref): Initialize cra.
3630 * struct.c (init_struct): Initialize prot.
3631 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3633 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3634 if EXPR contains no expressions.
3636 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3638 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3639 cause an infinite loop (???). So much for the algebraic
3640 equivalency of variable-sized arrays and alloca...
3642 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3644 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3645 a SCM boolean, not a C boolean.
3647 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3649 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3650 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3651 rules for raising scm_mtrigger. Previously, unfortunate but not
3652 unlikely circumstances could result in almost constant invokation
3653 of the gc. Now, this situations should be less likely, but they
3654 are not prevented completely.
3656 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3658 * numbers.c (scm_fuck): Procedure removed; looks like old test
3660 * numbers.h: Prototype removed.
3662 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3664 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3665 array to a pointer, to match my Nov 21 change in eval.c.
3667 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3669 * libguile.h: Added #include "libguile/backtrace.h", #include
3670 "libguile/stacks.h".
3672 * strings.c (scm_string scm_make_string scm_string_ref
3673 scm_string_set_x scm_string_equal_p scm_string_append):
3674 Bugfix according to scm patch from Aubrey Jaffer:
3675 Corrected long-standing
3676 (not (eqv? (integer->char 128)
3677 (string-ref (make-string 1 (integer->char 128)) 0)))
3678 bug found by John Kozak <jk@noontide.demon.co.uk>.
3680 * strports.c, strports.h: Make scm_eval_0str return the value of
3681 the last expression evaluated (previously, it returned void).
3683 * strports.c, strports.h: New function: scm_read_0str. Does what
3686 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3688 * simpos.c (scm_getenv): return #f if string can't be found in the
3689 environment instead of throwing an exception, for compatibility
3690 with numerous other systems.
3692 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3694 * Makefile.am (.c.x): Use guile-snarf.
3695 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3697 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3699 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3701 * backtrace.c (scm_display_error_message): Made non-static, and
3702 renamed from display_error_message.
3703 * backtrace.h (scm_display_error_message): Added extern decl.
3704 * throw.c (uncaught_throw): Use it to display the error message.
3706 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3708 * inet_aton.c: Use #if 0, not #ifdef 0.
3710 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3712 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3713 to convert the returned value.
3714 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3715 the offset argument.
3717 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3719 Add new interface to catch/throw, usable from C as well as
3721 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3722 (scm_internal_catch): New function, replaces...
3723 (scm_catch_apply): Deleted.
3724 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3725 mechanism which is a bit more code, but can be used nicely from C
3726 and implement the Scheme semantics as well.
3727 (scm_internal_catch): This is the replacement; it's named after
3728 the analogous function in Emacs.
3729 (scm_catch): Reimplemented in terms of the above.
3730 (struct catch_body_data, catch_body, catch_handler): New
3731 functions, used by scm_catch.
3732 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3733 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3734 support for new cwdr.
3736 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3739 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3741 * acconfig.h: Added DYNAMIC_LINKING symbol.
3742 * configure.in: Add option and checks for dynamic linking.
3743 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3744 dynl.h: New files for dynamic linking support.
3745 * Makefile.am (libguile_a_SOURCES):
3747 (modinclude_HEADERS): Added "dynl.h".
3748 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3750 * init.c (scm_boot_guile_1): Call
3751 scm_init_dynamic_linking to initialize dynamic linking support.
3753 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3755 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3756 (as we Schemers say). It needs to be global, so that I can tweak
3757 it for the proper operation of unexec.
3758 (scm_boot_guile_1_live): New variable, see above.
3760 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3762 * guile-snarf.sh: Removed.
3763 * PLUGIN/guile.libs: Added dependency for -lm.
3764 * acinclude.m4: Renamed from aclocal.m4.
3765 * PLUGIN/greet: Removed.
3766 * Makefile.am, aclocal.m4: New files.
3767 * configure.in: Updated for Automake.
3769 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3771 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3772 and not top_level_lookup_thunk_var.
3774 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3776 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3778 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3780 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3781 Scheme function, instead of syntax. Single argument is now a
3784 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3786 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3787 scm_ra_divide): Properly terminate statements passed as arguments
3788 to IVDEP macros. (Thanks to Bernard Urban.)
3790 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
3791 with non-constant sizes. (Thanks to Bernard Urban.)
3793 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3795 It's an "eval closure", not an "eval thunk." A thunk is a
3796 function of no arguments.
3797 * root.h (struct scm_root_state): Renamed
3798 top_level_lookup_closure_var from top_level_lookup_thunk_var.
3799 (scm_top_level_lookup_closure_var): Renamed from
3800 scm_top_level_lookup_thunk_var.
3801 * root.c (mark_root): Uses changed.
3802 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
3803 * init.c (scm_start_stack): Uses changed.
3804 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
3805 Change scheme-visible name to *top-level-lookup-closure* from
3806 *top-level-lookup-thunk*.
3808 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
3810 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
3811 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
3813 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
3815 * gc.c (struct scm_heap_seg_data): Doc fixes.
3817 * gc.c (scm_gc_sweep): Empty all segments' freelists before
3818 sweeping. Then, prepend each segment's free cells to its
3819 freelist, rather than wiping out the old value. (Thanks to Marius
3822 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
3823 scm_check_freelist, scm_debug_newcell): New functions and
3824 variables, for debugging freelist problems.
3825 * pairs.h (SCM_NEWCELL): New debugging version added.
3826 * gc.h (scm_debug_newcell): Added extern declaration, used by
3827 debugging version of SCM_NEWCELL.
3829 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3831 On some systems <libc.h> conflicts with <unistd.h>, and should not
3832 be #included at all.
3833 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
3834 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
3835 * configure.in: Call it.
3836 * posix.c, filesys.c: Use its results to decide whether or not to
3838 * configure, scmconfig.h.in: Rebuilt with autoconf and
3841 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3843 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
3844 pointer to the stdio stream before calling scm_setbuf0, so the
3845 latter will be able to retrieve it. I'm surprised this didn't
3846 segfault earlier. (Thanks to Christopher Lee.)
3848 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3850 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
3853 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3855 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
3856 number of stack narrowing specifier pairs. The first specifier in
3857 a pair controls inner border, the second the outer border. A
3858 number means cut that number of frames, a procedure object means
3859 cut until that object is found in operator position in a frame.
3861 * root.c (cwdr): Bugfix.
3863 * read.c: Recording of positions disabled by default.
3865 * procs.c (scm_closure_p): New function.
3867 * posix.c (scm_tmpnam): New function.
3869 * load.c: Added #include "throw.h".
3870 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
3873 * load.c, load.h (scm_read_and_eval_x): New function.
3875 * eval.c: Renamed debug option "deval" to "debug".
3877 (scm_eval_x): `eval!' is no longer accessible from the scheme
3878 level. Motivation: We can't allow operations which introduce
3879 glocs into the scheme level. Guile's type system can't handle
3880 these as data. Use `eval' or `read-and-eval!' as replacement.
3882 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
3883 SCM_CONSP since this is a macro!; Set vframe.prev to
3884 scm_last_debug_frame instead of 0. In this way we can look
3885 "above" the virtual start stack frame if we wish.
3886 (scm_debug_hang): New function: Useful for debugging Guile in
3887 certain tricky situations. Will probably be removed later...
3889 * debug.h: Changed semantics of debug option "backtrace". This
3890 option now only indicates whether we want automatic backtrace at
3893 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3895 * ports.c: #include "filesys.h"
3896 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
3898 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
3899 Motivation: This is system specific code which is related to file
3900 I/O. It also may use select. Added code by Gary Houston to
3901 detect presence of character in stdio buffers.
3903 * libguile.h: #include "libguile/libpath.h"
3905 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
3906 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
3907 SCM_SITE_DIR; Install libpath.h among the other include files.
3909 * load.c, load.h (scm_sys_package_data_dir): New function.
3911 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3913 * stacks.h: Bugfix: Don't use tail-array length field as stack
3914 length field! This screwed GC.
3916 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3918 * _scm.h: Added #ifndef around definition of macros min and max.
3920 * __scm.h: Added hooks for threads to plugin to in ints protection
3921 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
3922 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
3923 the main code in these macros duplicated and spread over multiple
3924 files. Renamed SCM_THREADS_SWITCHING_CODE ->
3925 SCM_THREAD_SWITCHING_CODE.
3927 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
3929 * snarf.h: New file.
3930 * guile-snarf.sh: New file.
3931 * Makefile.in (inner_h_files): Added snarf.h
3932 (ancillary, install, uninstall, distclean): Added actions for
3934 (.c.x): Use guile-snarf.
3935 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
3936 (gen_c_files): Note that these depend on guile-snarf.
3937 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
3938 now in "snarf.h". Added #include "snarf.h" to get them.
3939 * libguile.h: Added #include "snarf.h".
3940 (Patches applied and tweaked by Jim Blandy.)
3942 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3944 * socket.c: Use K&R style declaration for 'close'; the GNU coding
3945 standards suggest against providing prototypes for system
3946 functions. Thanks to Greg Troxel.
3948 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3950 * strports.c (scm_eval_0str): New function.
3951 #include "read.h", to get prototype for scm_read.
3952 * Makefile.in (strports.o): Update dependencies.
3953 * strports.h: New prototype.
3955 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
3956 scheme name from "int?" to "integer?". It seems to do the job.
3957 * numbers.h: Rename prototype too.
3958 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
3961 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
3962 scm_num_eq_p): Rename these according to R4RS conventions: call
3963 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
3964 to making libguile R4RS compliant without ice-9...
3966 * load.c (scm_sys_search_load_path): Search for files under all
3967 extensions listed in the %load-extensions variable. If FILENAME
3968 is absolute, return it unchanged, without searching the load path.
3969 (scm_loc_load_extensions): New variable, pointing to
3970 %load-extensions' value cell.
3971 (scm_init_load): Initialize it, and the value it points to.
3972 (scm_primitive_load_path): Improve error reporting.
3974 * load.c (scm_loc_load_hook): New variable, pointing to value cell
3975 of new Scheme variable %load-hook.
3976 (scm_primitive_load): Apply %load-hook to filename.
3978 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
3980 * configure.in: add tests for figuring out whether buffered data
3981 is available in a FILE structure, which is needed by char-ready.
3983 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
3986 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
3987 exceptions using misc_error instead of syserror. It seems a bit
3988 odd to throw an exception if a string can't be found in the
3989 environment, but it's consistent with open-file, stat etc.
3990 (simpos.h): remove sys_ from getenv.
3992 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
3993 occurs, throw an error instead of returning errno. Return value
3995 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
3997 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
3999 * filesys.c (scm_stat2scm): derive file type and permissions from
4000 the stat mode and append them to the returned vector.
4001 There isn't much overhead in doing this and it avoids the need to
4002 work with S_IRUSR et al. in Scheme.
4003 Define symbols scm_sym_regular etc.
4004 (scm_init_filesys): don't intern S_IRUSR etc.
4006 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4007 and s_primitive_load_path.
4009 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4011 * error.h: don't declare error symbols. prototype for scm_misc_error.
4013 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4016 * error.c: use SCM_SYMBOL to set up error keys.
4017 scm_misc_error: new procedure.
4019 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4021 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4022 between `#!' and `!#' is ignored.
4023 (skip_scsh_block_comment): New function.
4025 * feature.c (scm_set_program_arguments): New argument, FIRST.
4026 * feature.h: Update prototype.
4027 * init.c (scm_boot_guile_1): Pass new argument to
4028 scm_set_program_arguments.
4030 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4032 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4033 (scm_boot_guile): Call scm_set_program_arguments here, later than
4034 the old initialization.
4036 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4037 initialization procedure.
4038 - Delete in, out, err arguments; there are other perfectly good
4039 ways to override these when desired.
4040 - Delete result argument; this function shouldn't ever return.
4041 - Rename init_func argument to main_func, for less confusion.
4042 - Delete boot_cmd argument; main_func is more general.
4043 -Add 'closure' argument, to help people pass data to main_func
4044 without resorting to global variables.
4045 - Abort if reentered; don't bother returning an error code.
4046 - Call scm_init_standard_ports to set up the default/current
4047 standard ports; no need to pass them to scm_start_stack.
4048 - Remove code to evaluate the boot_cmd, and start the repl; let
4049 the user do something like that in main_func if they want.
4050 - Remove code to package up a return value; main_func can do any
4052 - Call exit (0), instead of returning.
4053 (scm_start_stack): Don't initialize the I/O ports here; that's
4054 weird. Delete in, out, err arguments. Move guts to
4055 scm_init_standard_ports, scm_stdio_to_port.
4056 (scm_init_standard_ports): New function, to set up current and
4057 default standard ports.
4058 (scm_start_stack, scm_restart_stack): Make these static.
4059 * init.h (scm_boot_guile): Adjust declaration.
4060 (scm_start_stack, scm_restart_stack): Remove externally
4061 visible declarations for these.
4062 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4064 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4065 written out several times in scm_start_stack.
4066 * fports.h: New declaration for the above.
4068 * feature.c (scm_set_program_arguments): New function.
4069 * feature.h: New declaration for the above.
4071 * ports.c: Formatting tweak.
4073 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4075 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4076 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4077 for obtaining the address of a car or cdr field. Motivation:
4078 &SCM_CXR make assumptions about the internal structure of the
4081 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4082 Motivation: see SCM_CXRLOC.
4084 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4085 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4086 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4087 Motivation: Safer use. Some other macros are defined in terms of
4088 these operations. If these are defined using the SCM_SETCXR
4089 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4090 to inefficiency and an <e1> with side-effects could potentially
4091 break. Also, these particular operations are heavily utilized in
4092 the garbage collector. In unoptimized code there will be a
4095 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4096 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4097 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4098 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4099 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4100 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4101 vports.c: Cleaned up use of pairs: Don't make any special
4102 assumptions about the internal structure of selectors and
4103 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4104 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4105 (Among other things, this change makes it easier to build Guile
4106 with certain compilers which have problems with casted lvalues.)
4108 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4110 * stacks.c: Improve selection of relevant stack frames when making
4111 a stack object. Introduce one level of indirection in the stack
4112 object to make it possible to "narrow" to a certain region of the
4113 stack. This facilitates making use of more clever algorithms (not
4114 implemented) for selecting relevant frames and gives a cleaner
4115 design since selection of frames can be done independently of
4116 extraction of frames from the real stack.
4117 (scm_stack_id): Also take #t as argument which means look at
4120 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4121 Turn n_tail into an integer directly representing current number
4122 of frames in stack. Add field tail.
4124 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4126 * debug.c (scm_make_memoized): Made it available at scheme level.
4127 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4128 SCM_NIMP before applying heavier predicates in argument checking.
4129 (scm_local_eval): Also take memoized object as argument.
4131 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4132 aren't created with zero length, but should such a strange
4133 creature suddenly turn up...
4135 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4137 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4138 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4140 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4142 * variable.c (scm_make_variable): Make the name hint optional, as
4144 (anonymous_variable_sym): Renamed from variable_sym. All uses
4147 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4148 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4149 of scm_primitive_load_path was also changed to
4150 "primitive-load-path", from "%try-load-path". Callers changed.
4151 We'd like to respect the convention that a function named
4152 "try-mumble" should behave just like the function called "mumble",
4153 but return #f instead of signalling some error.
4154 * load.h: Rename prototypes.
4156 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4158 * print.c (make_print_state, grow_print_state), print.h: Modified
4159 the print state representation: Don't use a tail array for
4160 recording of circular references. Resizing of the print state
4161 structure invalidates the print state pointer. To avoid passing
4162 around an indirect print state reference to all printing
4163 functions, we instead let the print state reference a resizable
4166 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4168 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4169 Don't crash when passed an improper list terminated by a
4170 non-immediate value.
4172 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4174 Allocate data for structures on an eight-byte boundary, as
4175 required by the tagging system.
4176 * struct.c (alloc_struct): New function.
4177 (scm_make_struct, scm_make_vtable_vtable): Call it.
4178 * struct.h (scm_struct_n_extra_words): Bump to 3.
4179 (scm_struct_i_ptr): New "field".
4180 * gc.c (scm_gc_sweep): When we need to free the data, use the
4181 information stored by alloc_struct to find the beginning of the
4182 block allocated to the structure, so we can free it.
4184 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4186 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4189 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4190 (scm_debug_info): New member: id.
4192 * stacks.c: Stacks are now represented as structs; Stacks have an
4193 id given to them by `start-stack'.
4194 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4196 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4197 Changed stack representation.
4199 * debug.c (scm_procedure_name): Try procedure property `name' for
4200 compiled closures aswell.
4202 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4204 * eval.c: scm_i_name moved to gsubr.c
4205 (scm_m_define): Record names of all kinds of procedure
4206 objects. (Earlier, only closures were recorded.)
4208 * procprop.h: Added declaration of scm_i_name.
4210 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4211 (scm_make_gsubr): Record names of compiled closures.
4213 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4215 * debug.c, debug.h: Removed obsolete code.
4217 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4218 stacks.c: Renamed regs --> scm_contregs.
4220 * print.c (scm_free_print_state): Cleanup print state before
4221 returning it to pool. It is better to do it here than in
4222 scm_prin1 since scm_prin1 is called often.
4224 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4225 s_set_source_property_x): Check that first argument is a pair or a
4228 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4229 scm_i_line, scm_i_column and scm_i_breakpoint global.
4231 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4232 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4235 * debug.h: Added debug object smob declaration and macro
4238 * configure.in: Build with backtrace.o and stacks.o if debug
4241 * Makefile.in: Added entries for new files: backtrace.c,
4242 backtrace.h, stacks.c and stacks.h.
4244 * symbols.c (scm_sym2ovcell): Fixed documentation.
4246 * _scm.h (min, max): Added.
4248 * async.c: Moved `min' macro to _scm.h.
4250 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4251 SCM_BACKTRACE_INDENT.
4253 * eval.c: Added new debug options `maxdepth' and `indent'.
4255 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4257 * print.h: Added selector SCM_PRINT_STATE.
4259 * print.c: New functions: scm_make_print_state,
4260 scm_free_print_state.
4262 * print.h: Added declarations for scm_make_print_state,
4263 scm_free_print_state.
4265 * debug.c (scm_m_start_stack): New acro.
4267 * debug.h: Small cleanup.
4269 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4272 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

4297 More prototype-related changes from Marius Vollmer:
4298 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4299 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4300 * ports.h (ptobfuns): Added prototypes. This means some casting in
4302 * fports.c: Added casts for initializations, since the functions
4303 are defined to take FILE * as their stream argument, not SCM.
4304 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4305 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4306 to `char *str_data' to conform to prototype.
4308 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4310 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4312 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4314 * stime.c, stime.h: use SCM_P method.
4316 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4318 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4319 be given at least two arguments. Insist that lst's last element
4320 be a list, but don't make any requirements of its predecessors.
4322 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4324 * eval.c (scm_nconc2last): Revert last change; there seems to be
4325 other stuff going on here.
4327 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4329 * eval.c (scm_nconc2last): Make sure that each element of lst
4330 (which is a list of argument lists, except for the tail) is a
4331 proper list, i.e., finite and terminated by '().
4333 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4335 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4338 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4339 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4342 * vectors.c (scm_make_vector): Fill vectors with the undefined
4343 value, to help make Guile Scheme code more portable to other
4346 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4347 * symbols.h, tags.h: Doc fixes.
4349 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4351 * async.c (scm_take_signal): Doc fixes.
4353 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4355 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4356 want to subtract it from the modulus; we just want to leave it
4359 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4361 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4364 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4366 * throw.c (scm_catch_apply): Finished implementation of
4369 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4371 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4373 (scm_init_filesys): set "i/o-extensions" feature.
4376 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4378 * Makefile.in (root.o): Correct dependencies.
4380 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4382 * Makefile.in: Added dependency entry for root.o.
4384 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4385 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4387 * init.c (scm_start_stack): Set initial root continuation number
4390 * procs.c: New function: scm_thunk_p.
4392 * procs.h: Added declarations of scm_thunk_p.
4394 * root.c: Renamed `call-with-new-root' -->
4395 `call-with-dynamic-root'.
4396 (cwdr): Removed allocation of new root state. This should be done
4397 separately by use of scm_make_root.
4398 (scm_apply_with_dynamic_root): New function: Does what it
4399 sounds like. Needed when spawning threads.
4401 * root.h: Added member last_debug_frame to root state.
4402 Added #include "libguile/debug.h"
4404 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4405 arguments. The motivation is that code in root.c needs catch
4406 functionality, and we want to avoid code duplication.
4407 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4408 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4409 handlers that run without popping the stack into the dynwind
4412 * throw.h: Added prototypes for scm_catch_apply and
4415 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4417 * root.h (scm_root, scm_set_root): Decouple thread support details
4418 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4419 SCM_SET_THREAD_LOCAL_DATA.
4421 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4422 and tortoise scanning loop.
4424 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4426 * Makefile.in: Rebuild dependencies.
4428 * libguile.h: #include "libguile/print.h" before "smob.h", since
4429 the latter uses the print_state structure.
4431 * throw.c (scm_ithrow): Use the correct variable when checking to
4432 see if a given element of scm_dynwinds is a valid catch.
4434 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4435 structure, abort; don't just silently ignore the garbage.
4437 * _scm.h: #include "print.h" here, since it seems to be used just
4439 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4440 strports.c, unif.h: Don't #include "print.h".
4442 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4444 * feature.h (scm_loc_features): Removed external declaration.
4445 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4447 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4449 * feature.c (scm_init_feature): Added threads feature (needs to be
4450 initialized here, since features doesn't exist when
4451 scm_init_threads is called).
4453 * libguile.h: Added #include "libguile/../threads/threads.h".
4454 (This is a kludge to get thread support working. This should be
4457 * configure.in, acconfig.h: Added flags for thread support.
4459 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4462 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4463 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4466 * _scm.h: Added conditional #include "threads.h"
4468 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4469 SCM_THREADS_SWITCHING_CODE.
4471 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4472 allocate the basic dynamic root object.
4473 (scm_boot_guile): Added call to scm_init_root.
4475 * root.c, root.h: Added root smob.
4476 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4477 functions: Implements dynamic roots mostly according to spec in
4478 SCM manual. Main difference is that the second argument is a
4479 throw handler rather than an error "thunk".
4481 * root.h: Added declaration of scm_init_root.
4483 * root.c: Added #include "genio.h", #include "smob.h", #include
4484 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4486 (scm_init_root): Added #include "root.x".
4488 * throw.c: Added #include "stackchk.h"
4489 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4490 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4491 can be used in scm_call_with_new_root; Added reenabling of stack
4492 checking when catching a throw.
4494 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4496 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4498 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4499 element is not found, as per R4RS.
4501 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4503 * list.c: Doc fixes throughout.
4505 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4507 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4508 declare the char * to be const. Avoids a warning in rgx.c.
4510 * ports.h: spelling fix.
4512 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4515 * load.c (scm_sys_try_load_path): throw an error if file not found
4516 (like it says it in NEWS).
4518 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4520 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4521 PROPS slot to '(), not #f; it's an empty alist.
4523 * throw.h, throw.c: Use SCM_P instead of #if hair.
4525 Remove special support for uncaught throws; see throw.c for
4527 * throw.c (uncaught_throw): New function.
4528 (scm_ithrow): Call uncaught_throw if we don't find a throw
4529 target; don't mess with scm_bad_throw_vcell.
4530 (scm_bad_throw_vcell): Variable deleted.
4531 (scm_init_throw): Don't initialize it.
4533 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4536 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4538 * numbers.c (scm_istr2int): If the number is short (as most
4539 numbers are), just call scm_small_istr2int to deal with it.
4540 (scm_small_istr2int): New function, created by un-#ifdefing the
4541 non-bignum version of scm_istr2int and renaming it.
4543 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4545 * load.c (scm_sys_try_load): don't check whether value returned
4546 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4547 Change the Scheme name from %try-load to primitive-load.
4549 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4550 Can avoid passing a message, allowing it to be derived in the
4551 error handler (e.g., if we want to throw to the key both from
4554 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4556 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4557 references now have a new appearance which is more compact and
4558 also gives a clue about what the target of the reference is.
4559 By setting parameters in the print state, more fancy printing can
4560 be achieved. This is used by the (not yet commited) backtrace
4563 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4565 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4568 * print.c: Added #include "struct.h". Removed function
4571 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4572 scm_iprin1. Removed prototype for scm_prlist.
4574 * arbiters.c (prinarb),
4575 async.c (print_async),
4576 debug.c (prindebugobj, prinmemoized),
4577 eval.c (prinprom, prinmacro),
4578 filesys.c (scm_fd_print, scm_dir_print),
4580 mallocs.c (prinmalloc),
4581 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4582 smob.h (scm_smobfuns),
4583 srcprop.c (prinsrcprops),
4585 unif.c, unif.h (scm_raprin1, rapr1),
4586 variable.c (prin_var): Changed argument `int writing' to
4587 `scm_print_state *pstate'.
4589 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4590 that it will be called before scm_init_print.
4592 * print.c (scm_prin1): Print states are now allocated when calling
4593 scm_prin1 and then passed around to all printing functions as an
4594 argument. A cache `print_state_pool' enables reuse of print
4596 (scm_make_print_state): New function.
4597 (scm_iprin1): Adaption to print states.
4598 (scm_iprlist): An initial "hare and tortoise" scan brings down
4599 time complexity to O (depth * N). (Better time complexity will be
4600 achieved when the printing code is completely rewritten.)
4602 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4604 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4605 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4606 it gets done whether or not the cache variable has a value.
4608 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4610 Distinguish #f and ().
4611 * __scm.h: #undef SICP.
4612 * pairs.h (SCM_EOL): Delete this definition, equating it with
4614 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4615 the value it used to have. Doc fixes, too.
4617 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4619 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4620 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4621 Lord's implementation of structs, allowing for tail arrays as
4622 described in the manual. Also fixed some bugs. (Both the interface
4623 and the implementation should be improved.)
4625 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4627 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4628 People who whish to see the source can do `(print-enable 'source)'.
4629 Removed #ifdef DEBUG_EXTENSIONS.
4631 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4633 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4634 integer (assuming for now accepting an integer is a good thing).
4636 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4637 %S will be used instead for write'ing arguments.
4639 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4640 asserts. fix a few other asserts.
4641 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4642 scm_uniform_vector_ref, scm_array_set_x,
4643 scm_dimensions_to_unform_array): change args in
4644 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4645 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4646 scm_substring_fill_x): likewise.
4647 gsubr.c (scm_gsubr_apply): likewise.
4648 eval.c (SCM_APPLY): likewise.
4650 * eval.c (4 places): replace scm_everr with lgh_error or
4653 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4654 scm_memory_error): new procedures.
4655 scm_everr: deleted. can use scm_wta, dropping first two args.
4656 scm_error: convert NULL subr to SCM_BOOL_F.
4658 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4661 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4664 * error.c, error.h: new error keys: scm_arg_type_key,
4665 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4667 scm_wta: reimplement using lgh_error instead of scm_everr.
4669 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4671 * gdbint.c: scm_lread now has one more argument.
4673 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4674 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4675 loading source from non-file ports, which, e. g., happens when
4676 using the Emacs interface).
4678 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4681 * read.c: Added code for recording of positions of source code
4682 expressions; New functions: recsexpr, scm_lreadrecparen;
4683 _scm_make_srcprops --> scm_make_srcprops
4684 (scm_flush_ws): Removed updating of positions counters. This work
4685 is already done by scm_gen_getc
4687 * read.h: Added prototype for scm_lreadrecparen
4689 * print.c: Added #include "alist.h"
4691 * eval.c: Added #include "hash.h"
4693 * eq.c: Added #include "ramap.h"
4695 * options.c: Documentation fixes.
4697 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4698 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4699 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4700 --> scm_make_srcprops
4702 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4703 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4704 function calls in the definition of the whash access macros.
4706 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4708 * init.c (scm_boot_guile): Add level of indirection to
4709 scm_boot_guile_1() to ensure that stack base pointer is properly
4710 initialized. There was no guarantee that variable i was the
4711 highest/lowest variable on stack (i.e. the call frame of
4712 scm_boot_guile was not completely protected from gc).
4714 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4716 * ports.h (scm_port_table): put back file_name, it will be used to
4717 support debugging. Undo related changes in fports.c, ioext.c,
4720 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4722 * ports.h (scm_port_table): remove file_name member for now, it seems
4724 * fports.c (scm_open_file): don't set file_name in PTAB.
4725 (prinfport): don't use file_name in PTAB.
4726 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4727 * ports.c (scm_add_to_port_table): don't intialize file_name.
4728 (scm_port_file_name): remove for now.
4729 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4731 * fports.h (scm_mkfile): prototype deleted.
4732 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4734 * debug.c, unif.c: use scm_out_of_range instead of
4735 wta for range errors (ASSERT still needs work).
4737 * error.c, error.h (scm_out_of_range): new procedure.
4739 * error.c, error.h (scm_out_of_range_key): new key.
4741 * posix.c (scm_sync): #else was missing.
4743 * error.c, error.h: append _key to names scm_num_overflow and
4746 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4747 of consing an empty list.
4748 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4749 of macros, saves code and string space.
4750 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4751 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4752 lower case. Rename scm_syserror_m to scm_syserror_msg.
4753 error.h: prototypes for new procedures.
4755 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4757 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4759 * error.c, error.h: setup scm_num_overflow key.
4761 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4762 Remove definition of SCM_OVSCM_FLOW.
4764 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4766 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4767 explicit message and args.
4769 * error.c, error.h, __scm.h: change system_error_sym to
4772 * error.c (system_error_sym): remove leading %% from the Scheme name
4775 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4777 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4779 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4780 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4781 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4782 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4783 renamed. (These were introduced by unsupervised name
4786 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4788 * print.c: Added code for detection of circular references during
4789 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4790 a hook for printing of closures (accessible via print options).
4791 This leads to a split of calls to scm_iprin1 into two classes:
4792 elementary print operations (e. g. the code which prints a smob)
4793 still use scm_iprin1 while top level calls (like scm_display) use
4794 scm_prin1. scm_prin1 begins by clearing the data structure used
4795 to record reference information.
4797 * print.h: Added declarations of scm_prin1 and scm_prlist.
4799 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
4801 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
4803 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
4805 * error.c (err_head): scm_iprin1 --> scm_prin1
4807 * debug.c: Adjusted header comment.
4811 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4813 * strerror.c: Doc fix.
4815 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4817 * gdbint.c (gdb_read): Now possible to run during GC.
4818 (unmark_port, remark_port): New functions.
4820 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
4822 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
4823 of allocating a new string object. Also, increase size by
4824 the factor 2 instead of 1.5.
4826 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
4828 * __scm.h (SCM_P): Corrected to run under traditional C.
4830 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
4833 * async.c: Calls to scm_sysintern corrected.
4835 * async.h (scm_async_clock): Redundant declaration removed.
4837 * continuations.c (scm_dynthrow): Redundant declaration removed.
4839 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
4840 Definition typos corrected.
4842 * debug.h: Missing declarations of functions in debug.c added
4845 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
4846 Missing declarations to functions in eval.c added.
4848 * filesys.c: Possibly uninitialized variable rv.
4850 * gc.h (scm_object_addr, scm_unhash_name): Missing
4851 declarations of functions defined in gc.c added.
4853 * genio.c: Possible typos str_data -> wstr_data. ???
4855 * genio.c: Possibly unintended shadowing of local variable
4856 `int c' (gotos out of scope of inner `c'). ???
4858 * init.c: Uninitialized `SCM last' may be used.
4860 * ioext.h: (scm_sys_isatty_p): Typo.
4862 * list.h (scm_list_head): Missing prototype for function in
4865 * numbers.c (scm_two_doubles): Changed from extern to static
4866 (is used only within numbers.c).
4868 * numbers.h: Repeated declarations removed.
4870 * ports.h (scm_close_all_ports_except): Declaration for the
4871 function defined in ports.c added.
4873 * posix.h: Missing declarations added.
4875 * procs.h (scm_make_subr_opt): Missing declaration added.
4877 * socket.h (scm_sys_gethost): Missing declaration added.
4879 * socket.h: Redundant declarations removed (they are in fdsocket.h).
4881 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
4882 Missing declarations added.
4884 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
4886 * struct.c: Uninitialized variable `SCM answer' may be used.
4888 * unif.c (l2ra): Declaration prototype.
4890 * unif.c (scm_array_equal_p): Dummy definition removed (it is
4891 defined in ramap.c).
4893 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
4894 Redundant declarations removed (they are in ramap.h).
4896 * variable.h (scm_make_udvariable,
4897 scm_make_undefined_variable): Declaration corrected to
4898 correspond variable.c.
4900 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
4901 Missing declarations added.
4903 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
4905 * Makefile.in (distclean): Don't forget to delete fd.h.
4907 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4909 * fd.h.in, tags.h: Trivial cleanups.
4911 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
4912 marksweep.h just declared functions from gc.c.
4913 * gc.h, libguile.h: Don't #include "marksweep.h".
4914 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4915 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
4916 dependencies updated.
4918 * libguile.h: Don't #include "files.h"; it's been deleted.
4920 * files.c (scm_sys_delete_file): Moved to filesys.c.
4921 File is now empty; deleted.
4923 * filesys.c: scm_sys_delete_file is now here. Remove
4924 #if's; they seem to rely on remnants of an old portability
4925 regimen. If the problems come up again, solve them properly,
4926 using autoconf. Specifically: Don't test M_SYSV, and #define
4927 remove to be unlink if it's #defined; don't use remove just
4928 because HAVE_STDC_HEADERS is #defined.
4929 * filesys.h: Add declarations for scm_sys_delete_file.
4930 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4931 files.o, files.h, files.c, and files.x.
4932 * init.c: Don't #include "files.h", and don't call scm_init_files.
4934 Use SCM_P instead of PROTO; the latter intrudes on the user's
4936 * params.h: Deleted; definition of SCM_P moved to...
4937 * __scm.h: ... here, where it replaces PROTO macro.
4938 * libguile.h, smob.h: Don't #include "params.h".
4939 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
4940 smob.h: Fix prototypes accordingly.
4941 * Makefile.in: Update dependencies.
4942 (inner_h_files): Remove params.h.
4944 * gc.c: #include "gc.h"; every module should include its header,
4945 to let the compiler cross-check the declarations against the
4948 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
4949 simpos.h: #include "libguile/__scm.h".
4951 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
4953 * init.c: Don't forget to #include smob.h and init.h.
4954 * Makefile.in: Dependencies updated.
4956 * smob.h: Use PROTO instead of #if __STDC__.
4958 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
4960 * __scm.h: Doc fixes.
4962 * __scm.h, libguile.h: Use "quotes" in the #includes, not
4963 <angles>; this allows `make depends' to work properly.
4965 * libguile.h: #include smob.h and pairs.h before the others; they
4966 define typedefs used by other headers.
4968 C files should #include only the header files they need, not
4969 libguile.h (which #includes all the header files); the pointless
4970 recompilation was wasting my time.
4971 * Makefile.in (all .o dependency lists): Regenerated.
4972 * libguile.h: Don't try to get a definition for size_t here...
4973 * __scm.h: Do it here.
4974 * _scm.h: Since this is the internal libguile header, put things
4975 here that all (or a majority) of the libguile files will want.
4976 Don't #include <libguile.h> here; that generates dependencies on
4977 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
4978 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
4979 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5076 * weaks.c: Get "weaks.h".
5078 * stackchk.h: #include "libguile/debug.h",
5080 * print.h, read.h: #include "options.h", since everyone who uses
5081 either of these files will need that.
5083 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5084 anyone who uses this file will need them to define the smob
5085 printing functions. Also, get markers.h, since people will need
5086 to #define the mark functions.
5088 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5089 * ports.h: ... to here.
5091 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5092 don't rely on archaic C default type rules.
5094 * fports.h: #include "libguile/ports.h", since you need that in
5095 order to parse this.
5097 * genio.h: #include "libguile/print.h", because you need that to
5098 parse this; don't bother #including "ports.h", since print.h gets
5101 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5103 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5104 this; it's now a reference to an element of *scm_root.
5106 * debug.h: Don't #include "options.h"; the compiler won't be able
5107 to find that once the headers are installed; instead, #include
5108 "libguile/options.h".
5109 * gc.h: Same, with marksweep.h.
5110 * mbstrings.h: Same, with symbols.h.
5111 * scmhob.h: Same, with _scm.h.
5112 * smob.h: Same, with params.h.
5114 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5115 C files; there's no need for this, and it forces recompilations
5118 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5120 * error.c (scm_error): declare scm_error_callback.
5122 * error.h: prototype for scm_error_callback.
5124 * __scm.h: define lgh_error.
5125 (SCM_SYSERROR): redefine using lgh_error.
5127 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5129 * error.c (scm_error): new procedure.
5131 * error.h: prototype for scm_error.
5133 * Makefile.in (install): install scmconfig.h from the current
5134 directory, not $(srcdir).
5136 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5138 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5139 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5140 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
5141 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,

5145 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5146 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5147 vports.h, weaks.h: #include "libguile/__scm.h", not
5148 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5149 dependencies are within libguile properly.
5151 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5153 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5154 when scmconfig.h doesn't exist.
5156 * load.c (scm_sys_try_load): Correct spelling.
5158 * feature.c (scm_loc_features): Make this static.
5160 * Makefile.in (libpath.h): Omit trailing slash from path. We
5161 shouldn't require it of users, so why put it here?
5163 Move code to initialize and search %load-path from ice-9 to C
5164 code, so we can use the load-path to find the ice-9 boot code;
5165 this makes it easier to run Guile without installing it. See
5166 corresponding changes in guile/Makefile.in.
5167 * feature.c: Move stuff concerned with the load path to load.c.
5168 (scm_compiled_library_path): Deleted.
5169 Don't #include libpath.h here.
5170 * feature.h: Don't mention scm_compiled_library_path.
5171 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5172 <sys/stat.h>, and <unistd.h> (if present).
5173 (R_OK): #define if the system hasn't deigned to.
5174 (scm_loc_load_path): New variable.
5175 (scm_init_load_path, scm_sys_search_load_path,
5176 scm_sys_try_load_path): New functions.
5177 (scm_init_load): Initialize scm_loc_load_path to point to the
5178 value cell of the Scheme %load-path variable.
5179 * load.h: Add declarations for scm_sys_search_load_path,
5180 scm_sys_try_load_path.
5181 * init.c: Call scm_init_load_path.
5182 * Makefile.in (feature.o, load.o): Dependencies updated.
5184 * load.c, load.h: Rewrite using PROTO macro.
5186 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5188 * gc.c (scm_cellp): New function: C predicate to determine if an
5189 SCM value can be regarded as a pointer to a cell on the heap.
5191 * gc.h: Added declaration of scm_cellp.
5193 * gdb_interface.h: New file: The GDB interface header from the GDB
5196 * gdbint.c: New file: GDB interface.
5198 * gdbint.h: New file: GDB interface.
5200 * libguile.h: Added #include <libguile/gdbint.h>.
5202 * init.c (scm_boot_guile): Added scm_init_gdbint.
5204 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5205 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5206 found if object files and source are kept separate).
5208 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5210 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5212 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5214 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5215 TK_SRC_DIR; they're not relevant any more.
5217 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5218 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5220 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5222 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5223 search path, so we can find the <libguile/MUMBLE.h> headers.
5225 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5227 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5228 implicit in the .c.o rule.
5229 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5232 Put the library path in a header file, instead of passing it on
5233 the command line in every compilation.
5234 * Makefile.in (libpath.h): New target.
5235 (feature.o): Depend on libpath.h.
5236 (clean): Delete libpath.h.
5237 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5238 * feature.c: ... #include "libpath.h" here.
5239 * .cvsignore: Ignore libpath.h.
5241 Don't install the unwashed masses of Guile header files in the
5242 main #include path; put most of them in a subdirectory called
5243 'libguile'. This avoids naming conflicts between Guile header
5244 files and system header files (of which there were a few).
5245 * Makefile.in (pkgincludedir): Deleted.
5246 (innerincludedir): New variable; this and $(includedir) are enough.
5247 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5248 (installed_h_files): Divide this up. Now this variable lists
5249 those header files which should go into $(includedir) (i.e. appear
5250 directly in the #include path), and ...
5251 (inner_h_files): ... this new variable says which files appear in
5252 a subdirectory, and are referred to as <libguile/mumble.h>.
5253 (h_files): List them both.
5254 (install): Create innerincludedir, not pkgincludedir. Put
5255 the installed_h_files and inner_h_files in their proper places.
5256 (uninstall): Corresponding changes.
5257 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5258 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5259 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5260 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5261 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5262 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5263 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5264 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5265 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5266 vports.h, weaks.h: Find __scm.h in its new location.
5267 * __scm.h: Find scmconfig.h and tags.h in their new locations
5268 (they're both "inner" files).
5270 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5272 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5274 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5276 * posix.c: Doc fixes.
5278 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5280 * socket.c: Don't include a prototype for inet_aton; just use a
5281 K&R style declaration, to avoid warnings but minimize the chance
5282 of conflicts with the system.
5284 On NextStep, <utime.h> doesn't define struct utime, unless we
5285 #define _POSIX_SOURCE before #including it.
5286 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5287 * acconfig.h: New comment text for above CPP symbol.
5288 * configure.in: Call it.
5289 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5291 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5293 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5294 testing for __EMX__.
5296 * posix.c: #include <libc.h>, if it exists.
5298 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5299 don't even know if the latter exists.
5301 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5302 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5303 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5305 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5307 (scm_init_posix): Use them when initializing the Scheme constants
5310 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5312 * Makefile.in (libdir, includedir, bindir): Use the
5313 autoconf-supplied values, instead of deriving them ourselves.
5314 (pkgincludedir, datadir, pkgdatadir): New variables.
5315 (install, uninstall): Put the header files in a special
5316 subdirectory, not in the main search path.
5318 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5319 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5321 * Makefile.in (IMPLPATH): Deleted; never used.
5323 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5324 on the Tcl/Tk source any more.
5325 (INCLUDE_CFLAGS): Remove references to the above.
5327 * Makefile.in (version.o): Corrected dependencies.
5329 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5331 * libguile.h: #include "version.h"
5333 * init.c (scm_boot_guile): Call scm_init_version.
5334 * gscm.c (gscm_run_scm): Call scm_init_version.
5336 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5337 GUILE_VERSION): AC_DEFINE these.
5338 (acconfig.h): #undef the above symbols.
5340 * Makefile.in (libobjs): Add version.o.
5341 (installed_h_files): Add version.h.
5342 (c_files): Add version.c.
5343 (gen_c_files): Add version.x.
5344 (version.o): New rule.
5345 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5346 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5347 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5348 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
5349 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5350 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5351 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5352 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5353 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5354 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5355 weaks.o): Add version.h to dependency lists.
5356 (markers.o): Remove duplicate rule.
5358 * version.h: New file.
5360 * version.c: New file.
5362 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5364 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5365 array; use it appropriately. Since GCC is quite happy to
5366 subscript functions, it never warned us about this; we should use
5367 -Wpointer-arith in the future. I guess we never tested
5370 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5372 * socket.c: Doc and copyright fixes.
5374 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5376 * debug.c: Fixed and improved gdb support.
5378 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5380 * socket.c: Added declaration of inet_aton to avoid compiler
5381 warning. (Hope this solution is correct.)
5383 * stime.c: Added declaration of ftime. (This is missing in
5386 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5388 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5390 * Makefile.in (c_files): add strerror.c.
5392 * strerror.c: new file from Emacs' sysdep.c.
5393 maybe configure should also check for sys_errlist.
5395 * configure.in (AC_REPLACE_FUNCS): add strerror.
5397 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5399 * debug.c (scm_init_debug): Added initialization for
5400 scm_evaluator_traps.
5402 * debug.h, debug.c: Various name changes.
5403 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5404 "debug-options-interface". See commentary in options.c.
5406 * options.h, options.c: Options now have documentation strings.
5407 Also added a long explanatory commentary.
5409 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5412 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5413 last_debug_info_frame is now updated in all cases.
5415 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5418 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5420 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5421 Added option STACK_CHECKING.
5423 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5425 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5427 * __scm.h: Removed symbols for debugging support.
5429 * acconfig.h: Added symbols for debugging support.
5431 * configure.in: Added user option for debugging support.
5432 --enable-debug will include the debugging code into libguile.a.
5434 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5435 scm_relocate_chunk_to_heap.
5437 * debug.c: New file: low-level debugging support. It also
5438 includes support for debugging with gdb. (The extensions to gdb
5439 are written by Per Bothner at Cygnus.)
5441 * debug.h: New file: low-level debugging support.
5443 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5444 argument pairs. Extensive modifications to the debugging
5445 evaluator. Added "SECTION:" commentaries to clarify what happens
5446 when, during double compilation. Renamed EVALIMP --> EVALIM.
5447 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5448 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5449 the beginning of the file. New procedure: scm_unmemocopy.
5450 Added some global state variables needed by the debugging
5451 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5452 check_entry, check_apply, check_exit, debug_options and
5453 evaluator_traps. New acro: undefine.
5455 * eval.h: Renamed EVAL --> XEVAL.
5457 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5458 --> scm_make_weak_key_hash_table.
5460 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5461 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5463 * libguile.h: Conditionally include debug.h
5465 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5466 scm_object_properties shouldn't return handle. `handle' now gets
5467 initialized in scm_set_object_properties_x. scm_object_properties
5468 doesn't any longer create an entry in scm_object_whash.
5470 * options.c: New file: handling of run time options.
5472 * options.h: New file: handling of run time options.
5474 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5476 * print.c: New procedure: scm_print_options
5478 * print.h: Defines for print options.
5480 * read.c: New procedure: scm_read_options
5482 * read.h: Defines for reader options.
5484 * root.h: Added scm_source_whash among scm_sys_protects.
5486 * srcprop.c: New file: source properties.
5488 * srcprop.h: New file: source properties.
5490 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5491 (Bug found by A. Green.)
5493 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5495 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5497 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5499 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5501 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5502 and should be called by the final client.
5504 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5506 * gc.h: Use the PROTO macro when declaring functions.
5507 * gc.c: Use the PROTO macro when declaring static functions.
5508 Remove the CPP hair around function definitions.
5510 * gc.c (scm_init_storage): Initialize scm_asyncs.
5512 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5513 preprocessor symbol; "__scm.h" is where it might get #defined.
5514 * __scm.h: Similar: #include <scmconfig.h> before testing
5517 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5519 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5521 * init.c (scm_boot_guile): Add init_func argument; call
5522 (*init_func) instead of calling scm_appinit; it's ucky to
5523 hard-code names for the user's procedures.
5524 * init.h (scm_boot_guile): Adjust declaration.
5526 * __scm.h (PROTO): New macro, for declaring functions with
5529 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5530 eliminate all the __STDC__ conditionals.
5531 (scm_boot_guile): Add declaration.
5532 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5533 Remove __STDC__ conditionals around function definitions; the
5534 declarations in init.h will provide the same information, more
5537 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5538 complain about it in the error message; the error message is
5539 adequate without that note, and there's nothing the user can do
5542 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5544 * Makefile.in (ancillary): Drop def.sed.
5546 * posix.c (scm_init_posix): Use numeric values, rather than
5547 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5548 F_OK. The symbols aren't available on some systems, and I'm
5549 pretty sure their values are fixed by common widespread practice.
5550 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5552 More functions unavailable on some systems.
5553 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5554 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5556 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5557 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5558 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5559 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5560 stub that signals an error as the #else.
5562 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5564 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5566 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5568 * unif.c: include ramap.h.
5570 * read.c (endif): case_insensative_p renamed case_insensitive_p.
5572 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
5574 * ports.c: include sys/ioctl.h.
5576 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5578 * configure.in: check for sys/ioctl.h.
5580 * ports.c: include <malloc.h> not "malloc.h".
5582 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5584 * fports.c: remove ttyname and tmpnam declarations.
5586 * posix.c: fewer ttyname declarations.
5588 * fports.c: include <string.h> not "string.h".
5590 * init.c, ioext.c: include string.h and unistd.h.
5592 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5594 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5595 genio.c, simpos.c, vports.c: include string.h.
5597 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5599 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5601 (scm_addr_buffer_size): change type from scm_sizet to int.
5602 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5603 from scm_sizet to int.
5605 * error.c: include unistd.h.
5607 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5610 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5612 * __scm.hd, def.sed: deleted.
5614 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5616 Changes for NeXT, suggested by Robert Brown.
5617 * configure.in: Call AC_TYPE_MODE_T.
5618 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5619 NeXT. Put header file list in alphabetical order.
5620 * configure, scmconfig.h.in: Regenerated.
5621 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5623 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5626 * acconfig.h: New file, providing documentation for the CPP
5627 symbols defined in configure.in
5628 * acconfig-1.5.h: Removed; superceded by the above.
5630 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5632 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5634 * fports.c (scm_open_file): don't return #f, throw error.
5636 * ioext.c (fileno): renamed from %fileno.
5637 (soft-fileno): deleted.
5639 * ports.c (scm_port_revealed): don't need to check for -1 from
5641 (scm_set_port_revealed_x): return unspecified, not #f.
5643 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5645 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5647 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5649 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
5651 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5653 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5654 This is necessary on Ultrix, and doesn't hurt portability.
5656 * Makefile.in (dist-dir): New target, implementing a new dist system.
5657 (installed_h_files): Put in alphabetical order.
5658 Remove duplicate entries for markers.h and unif.h.
5659 (c_files): Remove duplicate entries for markers.c.
5660 (ancillary): Renamed from anillery; all uses changed. Remove
5661 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5662 Remove all the ../doc/* files; doc/Makefile.in handles that.
5664 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5666 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5667 every if must have an else, or else the whole command has a
5668 non-zero exit code whenever the if's condition is false.
5670 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
5672 * posix.c: include string.h.
5674 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
5676 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
5679 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
5680 Remove leading % from scheme names.
5681 Do not return error values, call SCM_SYSERROR or similar.
5683 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
5685 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
5687 * struct.c (scm_init_struct): new file.
5689 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
5691 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
5692 (scm_list_head): added list-head for rapidly chopping argument
5693 lists off of longer lists (and similar).
5695 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
5697 * objprop.c (scm_object_property): assq the cdr of the whash
5698 handle for obj, not the handle itself.
5700 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
5702 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
5703 weak hash tables last of all marking to avoid an obscure gc bug.
5704 WARNING: circular lists stored in a weak hash table will hose us.
5706 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
5708 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
5709 new functions similar to scm_substring_move_left_x and
5710 scm_substring_move_right_x.
5712 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
5714 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
5717 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
5719 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
5721 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
5723 * strports.c (scm_strprint_obj): convenience function. C for
5724 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
5726 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
5727 removed to a separate library
5729 * init.c (scm_boot_guile): copied from guile-tcl.c.
5730 Initialization specific to tcl interpreters removed.
5732 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
5734 * ports.c (scm_ports_prehistory): size malloced here doesn't
5735 matter so long as it is non-0 (got rid of "* 4").
5737 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
5739 * gscm.h: gscm_mkarray eliminated (presumably was not being used
5740 since its definition was bogus).
5742 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
5744 * mallocs.[ch]: back again (for rx at least).
5746 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
5748 * ports.c: removed functions relating to the mapping between ports
5749 and descriptors. (That stuff is unix-specific and should be collected
5750 in a separate library).
5752 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
5753 (Tom Mckay@avanticorp.com)
5755 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
5757 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
5758 handled correctly (SCM_FREEP was applied to them) -- test for
5759 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
5760 being overwritten with #f. (brown@grettir.bibliotech.com)
5762 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
5764 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
5765 for a specific symbol or for all symbols.
5767 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
5769 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
5770 keys and weak values confused).
5772 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
5774 * list.c (scm_last_pair): map '()=>'()
5776 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
5778 * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
5779 Generalized assoc and hash-table functions.
5780 Factored pairs.c into multiple files.
5782 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
5784 * gscm.c (gscm_run_scm): got rid of objprop.
5786 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
5788 * genio.c (scm_getc):
5789 NOTE: fgetc may not be interruptable.
5791 * procprop.c (scm_stand_in_scm_proc):

5927 initialization to fix a race condition.
5929 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
