1 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
3 * alloca.c (alloca): Undo yesterday's changes, and simply call
4 malloc directly for storage, and abort if we don't get what we
5 want. The situation is much simpler --- just call malloc. Emacs
6 has bizarre/evil requirements (signal handlers might malloc unless
7 you set this global flag, so you have to set the flag around all
8 calls to malloc) which we are certainly not going to conform to,
9 so we can do the simple and obvious thing.
11 * coop.c (coop_condition_variable_wait): Make this function
12 static. It's only useful internally --- you should never just
13 wait on a condition variable.
14 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
16 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
18 * unif.c (scm_array_set_x): Accept any kind of number as an
19 element for a uniform vector of doubles. This is more consistent
20 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
22 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
23 works; I can't conveniently test it myself. (Thanks to Dvid
24 Tillman for the bug report.)
28 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
29 from here, not from scm_compile_shell_switches (which is a pretty
31 (scm_load_startup_files): New function.
32 (scm_ice_9_already_loaded): Variable moved to here from script.c.
33 * script.c (scm_compile_shell_switches): Don't load the startup
35 (scm_ice_9_already_loaded): Variable moved.
36 * init.c (scm_load_startup_files): Prototype for new function.
37 * gh_init.c (gh_enter): Doc fix.
39 1998-10-03 <jimb@savonarola.red-bean.com>
41 Some anti-warning changes from Greg Harvey.
42 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
43 warnings when it doesn't understand our NORETURN declarations in
45 * posix.c (scm_mknod): Similar.
47 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
49 * posix.c (scm_getpwuid): If we can't find an entry, return our
50 own message, instead of using scm_syserror --- the getpwMUMBLE
51 functions don't set `errno' to anything interesting.
53 1998-10-03 <jimb@savonarola.red-bean.com>
55 Get rid of warnings from the cooperative threading system.
56 * threads.h (scm_single_thread_p, scm_yield,
57 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
58 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
59 scm_wait_condition_variable, scm_signal_condition_variable): Add
60 prototypes for these Scheme-visible functions.
61 * coop-defs.h (coop_next_runnable_thread,
62 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
63 Prototypes for these here, even though they're from iselect.c.
64 (coop_condition_variable_wait, coop_join): Add prototypes.
65 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
66 scm_threads_free_condvar): Make these smob functions static.
67 * coop-threads.h (coop_init): Give this a real prototype.
68 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
69 (coop_next_runnable_thread): No need to provide prototype; it's in
72 * scmconfig.h.in: .detarenegeR
74 * iselect.c, threads.c: Doc fixes.
76 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
78 * Makefile.in: Regenerated with a patched automake, to get
79 dependency generation right when using EGCS.
81 * inet_aton.c (inet_aton): Add prototype, to remove compiler
82 warning. (Thanks to Robert Pluim.)
84 * inet_aton.c (inet_aton): Reassure the compiler that the
85 arguments to the <ctype.h> macros are all unsigned characters, not
88 1998-10-03 <jimb@savonarola.red-bean.com>
90 Getting rid of more warnings...
91 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
92 today's change to ../configure.in.
93 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
94 * scmconfig.h.in: Regenertaded.de.,.__
95 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
96 (scm_localtime, scm_mktime): Use a const char * to manipulate the
99 * readline.c: Doc fix.
100 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
101 * readline.h (scm_filename_completion_function): Add prototype.
102 (scm_init_readline): Make this into a prototype.
104 * readline.c (scm_filename_completion_function): Use SCM_PROC to
105 declare this, instead of calling scm_make_subr manually.
107 1998-10-02 <jimb@savonarola.red-bean.com>
109 * readline.h (scm_init_readline): Add prototype for this.
110 (scm_init_readline): Make this a real prototype.
112 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
114 Warning fixes from Maciej Stachowiak:
115 * backtrace.h (scm_display_application, scm_backtrace): Add
117 * debug.c (scm_m_start_stack): Make this function static.
118 * fluids.h (scm_fluid_p): Add prototype.
119 * procprop.c (scm_i_procedure_arity): Make this function static.
120 * regex-posix.c (scm_regexp_error_msg): Make this function static.
121 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
122 * root.h (scm_dynamic_root): Add external prototype.
123 * scmsigs.h (scm_usleep): Add external prototype.
124 * script.h (scm_init_script): Use prototype, not K&R decl.
125 * stacks.h (scm_stack_id): Add external prototype.
126 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
128 1998-09-30 Mark Galassi <rosalia@cygnus.com>
130 * gh.h: took out the definitions of vset and vref, since they are
131 replaced by the proper vector routines that correspond to the R4RS
134 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
136 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
137 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
138 third argument, a C expression that should result in a SCM value,
139 which is used to initialize the variable. Reimplemented
140 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
143 * version.h (scm_libguile_config_stamp): Add prototype.
144 (From Maciej Stachowiak.)
146 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
148 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
149 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
151 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
153 * print.c (scm_iprin1): Rather than having one i, and using it in
154 several places, declare a fresh i local to each block where it is
155 used, and give it a signedness appropriate to its use in each case.
158 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
161 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
162 signed/unsigned clashes.
164 * posix.h (scm_tmpnam): Added prototype.
166 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
167 scm_make_subclass_object): Add external prototypes.
169 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
170 comparison is okay here.
172 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
174 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
175 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
177 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
180 * load.c (swap_port): Make this function static.
182 * load.c (scm_search_path): Make max_path_len and max_ext_len
183 unsigned, since they're compared against string sizes.
185 * load.c (init_build_info): Make i unsigned.
187 * ioext.h (scm_read_line): Add prototype.
189 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
190 scm_hash_fn_remove_x): Make hash bucket index local variable k
191 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
192 accurately as possible.
194 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
195 comparisons, and range checking to make sure those casts are
198 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
199 signed/unsigned comparisons.
201 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
202 avoid signed/unsigned comparisons.
203 * smob.h (scm_numsmob): Change extern declaration to match.
205 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
206 avoid signed/unsigned comparisons.
207 * ports.h (scm_numptob): Change extern declaration to match.
208 (scm_current_load_port, scm_set_port_line_x,
209 scm_set_port_column_x): New prototypes.
211 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
212 test code, and it causes warnings.
214 * gh.h (gh_int2scmb, gh_uniform_vector_length,
215 gh_uniform_vector_ref): Added prototypes.
217 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
218 debugging support unconditionally. That's backtrace.c, stack.c,
219 debug.c, and srcprop.c.
220 (EXTRA_libguile_la_SOURCES): Omit those from here.
221 * Makefile.in: Regenerated.
223 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
225 * options.c (scm_options): Bugfix: Allow empty list of options!
227 * debug.c, debug.h (scm_single_step): Removed.
228 (scm_with_traps): New procedure. This procedure could easily be
229 written in Scheme but needs to be highly optimized.
231 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
233 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
234 Check SCM_TRAPS_P before trapping.
236 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
238 Changes to avoid signed/unsigned comparison warnings.
239 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
240 (scm_gc_sweep): Make n and j local to the blocks they're used in,
241 so they can have appropriate types for each application. Make i
242 signed. Use initializers in some spots. I'll probably pay for
244 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
245 (scm_must_realloc): Make nm unsigned.
246 (init_heap_seg): Make new_seg_index and n_new_objects signed.
247 (scm_init_storage): Use prototype-style definition, and make the
249 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
250 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
252 * filesys.c (scm_readlink): Make local vars rv and size ints, to
253 avoid signed/unsigned comparison warnings, and because the return
254 value of readlink may be -1. Don't bother casting the third
255 argument to readlink.
257 * filesys.c (scm_dirname, scm_basename): Move these to their own
258 page, at the end of the file.
259 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
261 * eval.h (scm_eval_options_interface): Add external prototype for this.
262 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
264 * eval.c (scm_lookupcar1): Make this static.
266 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
267 Make these prototype declarations, not K&R-style.
269 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
270 unsigned comparison warning.
272 * appinit.c: File removed. It had a single function in it, empty,
273 whose reason for existence is explained in no documentation or
274 comment. I think it's there as a default for some Tcl-style
275 initialization, but Tcl abandoned that approach a while ago.
276 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
277 (BUILT_SOURCES): Remove appinit.x.
278 * Makefile.in: Regenerated.
280 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
282 * Makefile.in: Regenerated using the last public version of
283 automake, not the hacked Cygnus version.
285 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
287 Remove Totoro kludge.
288 * Makefile.in, scmconfig.h.in: Regenerated.
289 * init.c, readline.c: Don't check if TOTORO is #defined.
291 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
293 * Makefile.am: Adjust for new thread configuration system.
294 (INCLUDES): Include the value of THREAD_CPPFLAGS.
295 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
297 (THREAD_LIBS): Definition deleted; automake will generate such
298 things automatically.
299 * Makefile.in: Regenerated.
301 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
303 Simplify smob and port marking; set the mark bit in the generic
304 marking code, and make marker routines only responsible for
305 turning up outgoing pointers.
306 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
307 before calling the marking function. Don't call the marking
308 function if it's zero.
309 * markers.c (scm_mark0): Just return #f. This function isn't
310 necessary at all now, but it's harmless to call it. We'll leave
311 it in so other folks' code doesn't croak at link time.
312 (scm_markcdr): Don't call SCM_SETGC8MARK.
313 * async.c (mark_async): Don't call SCM_SETGC8MARK.
314 * dynl.c (mark_dynl_obj): Same.
315 * root.c (mark_root): Same.
316 * srcprop.c (marksrcprops): Same.
317 * unif.c (markra): Same.
318 * variable.c (scm_markvar): Same.
319 * ports.c (scm_markstream): Same.
320 (void_port_ptob): Specify zero for our marking function.
321 * debug.c (debugobjsmob): Same.
322 * dynwind.c (guardsmob): Same.
323 * filesys.c (dir_smob): Same.
324 * fluids.c (fluid_smob): Same.
325 * fports.c (scm_fptob, scm_pipob): Same.
326 * mallocs.c (mallocsmob): Same.
327 * regex-posix.c (regex_t_smob): Same.
328 * smob.c (freecell, flob, bigob): Same.
329 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
330 * throw.c (jbsmob, lazy_catch_funs): Same.
332 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
334 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
335 scm_copy_tree on code in order not to let memoized code to leak
336 out. Thus, scm_copy_tree needs to copy vectors as well since
337 quasiquote can introduce evaluated code also inside vector
340 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
342 * eval.c (scm_copy_tree): Removed ability to copy vectors.
344 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
345 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
348 * unif.c: Say that ivect and uvect are of type signed and unsigned
349 long instead of int in commentary so that it correctly describes
352 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
354 * stime.c: Removed declaration of strptime. (It should be
355 declared by the system headers. If it turns out that some systems
356 don't, we'll handle that then.) (Thanks to Greg Troxel.)
358 * stime.h: Renamed TIMEH --> STIMEH
360 * backtrace.c (scm_display_error, scm_display_backtrace): In order
361 to increase portability, don't use structure assignment.
362 (Thanks to Nicolas Neuss.)
364 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
366 (finalize_fd_sets): Added empty statement after last case label.
367 (Thanks to Nicolas Neuss.)
369 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
372 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
374 * init.c, readline.c: OK, I won't have these readline.x bug
375 reports anymore. We've had them since April. The current reason
376 is a completely unintelligible failure of totoro.red-bean.com to
377 do the test for rl_getc_function in libreadline correctly. This
378 kludge overrides the test if we're on totoro so that the snapshot
379 generation process can work.
381 * readline.c: Define a strdup replacement if not existent on system.
383 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
385 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
386 This change makes scm_make_vector R5RS compatible. We cannot keep
387 the third argument since people want to be able to deduce the form
388 of the C function call only by looking at R5RS. (At the same time
389 we have removed some unnecessary complexity!)
391 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
392 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
393 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
394 argument in call to scm_make_vector.
396 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
398 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
399 This macro is useful in applications.
401 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
403 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
404 (scm_parse_path, scm_search_path): New Scheme level procedures.
406 * load.h (scm_internal_parse_path, scm_parse_path,
407 scm_search_path): Declared.
409 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
411 * filesys.c (dirname, basename): New procedures.
413 * init.c (scm_boot_guile_1): Removed condition around
416 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
417 new data type (guards) for representation of C level guards and
418 data on the wind chain.
419 (scm_internal_dynamic_wind): New function.
421 * dynwind.h: Declare scm_internal_dynamic_wind.
423 * root.h (scm_root_state): Added scm_cur_loadp.
425 * root.c (mark_root): Added comment about cur_loadp.
427 * load.c: #include "dynwind.h";
428 (scm_primitive_load): Use scm_inner_dynamic_wind to update
431 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
433 * ports.c (current-load-port): New procedure.
435 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
437 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
438 not a tty, return #f.
440 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
441 to Julian Satchell and Roland Kaufmann.)
443 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
444 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
446 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
448 * debug.h, debug.c (scm_start_stack): New function. Implements
449 the guts of old scm_m_start_stack.
451 * debug.c (scm_m_start_stack): Use scm_start_stack.
453 * init.c (scm_start_stack, scm_restart_stack): Renamed to
454 start_stack and restart_stack. (These have static scope.)
456 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
458 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
459 readline functions to come in release 2.3. (Thanks to Chet
461 (handle_errors): Use the above functions.
463 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
465 * readline.c: Improvements for readline support: Handle errors
466 better; Implement before-read-hook.
468 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
470 * init.c (scm_boot_guile_1), readline.c: Test for
471 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
472 assure that we have version >= 2.1.)
474 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
476 * readline.c (scm_readline): Defer interrupts while we're calling
479 * readline.c (scm_add_history): Bugfix: Do strdup before giving
480 away the string to add_history.
481 (completion_function): Do completion for readline. (Thanks to
483 (scm_filename_completion_function): New procedure: Filename
485 (current_input_getc): New function. Use this one instead of
486 standard getc from readline.
488 * throw.c, throw.h (scm_handle_by_throw): New function: This
489 handler throws errors to next handler on the dynwind chain.
491 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
493 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
496 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
498 * procprop.c (scm_i_procedure_arity): New function. Returns arity
500 (scm_procedure_properties): Modified to return arity together with
502 (scm_procedure_property): Added the read-only property `arity'.
503 (scm_set_procedure_property_x): It is an error to set the `arity'
506 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
507 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
509 * procprop.h (scm_sym_arity): New symbol.
511 * objects.c (scm_set_object_procedure_x): New procedure: Use this
512 to set the dispatch procedure of an operator or entity object.
514 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
515 Made procedure slots read-only.
517 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
518 scm_tcs_cons_gloc case in zero args switch; Fixed args
519 construction for operators in scm_tcs_cons_gloc case in two args
522 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
524 * fluids.c: Removed use of assert.h (in order to avoid
527 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
529 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
531 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
532 change makes the evaluator safer at the cost of evaluation speed.
533 It handles the case when the user has added a non-immediate
534 improper end of the application form, e.g., `(+ 0 . x)'.
535 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
536 minimize the extra cost as much as possible. The new code is
537 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
538 problem with structs planted directly in the code (e.g. by a
539 macro). This no longer causes segmentation fault. (Thanks to
542 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
543 arg `proc' in order to be able to throw errors; New argument
546 * Removed extra #include "debug.h"
548 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
550 * scmsigs.c: Declare usleep as returning void on some systems.
551 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
554 * coop.c (usleep): Return void on some systems.
556 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
558 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
560 * coop.c: Changed return type of usleep to int.
562 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
563 isn't found in the OS.
565 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
566 isn't enabled. (Thought that I had made this change ages ago...)
568 * iselect.c: Declare bzero if not defined by OS.
570 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
572 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
573 condition. (Thanks to John Tobey.)
575 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
576 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
579 * __scm.h: Start the long-term project of moving to POSIX threads.
580 Phase 1: Classification of all critical sections.
581 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
582 for A sections. (See comments in __scm.h for details.)
584 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
585 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
587 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
589 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
590 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
591 (libpath.h, versiondat.h): Replaced dependency on Makefile with
592 dependencies on $(srcdir)/Makefile.in
593 $(top_builddir)/config.status in order to avoid circularity.
595 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
596 from argc if argc was 0 initially.
598 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
599 in generation of libpath.h.
601 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
603 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
604 libguile from 2 to 3.
606 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
608 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
610 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
612 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
613 scm_set_port_column_x, scm_port_filename,
614 scm_set_port_filename_x): Removed optional arguments. Added
615 proper argument checking.
617 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
618 stack size in machine words.
620 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
621 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
622 to Ole Myren Röhne.)
624 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
626 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
627 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
629 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
632 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
633 procedure apply: Copy argument lists before pushing them unto the
634 environment so that the environment won't get mutated due to
635 manipulation of procedure arguments. This should perhaps be
636 regarded as a temporary solution until someone finds a more
637 efficient one. (Thanks to Maciej Stachowiak.)
639 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
641 * script.c (scm_compile_shell_switches): Use "guile" as default
642 zero arg if argc is NULL.
644 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
646 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
647 is zero. (Thanks to Dirk Herrmann.)
649 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
651 * ports.c (scm_add_to_port_table): First line is now line 0
652 (was 1). (Interface changed according to suggestion by Per
655 * backtrace.c (display_header): Add 1 to line and column numbers
656 when presenting them to the user.
658 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
659 from debug.c --> eval.c
661 * eval.h, eval.c (scm_eval_options_interface): New options
663 (SCM_EVAL_STACK): New option: Size of newly created stacks,
664 i.e. stacks for new threads.
666 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
668 * eval.c (unsafe_setjmp): Removed with #if 0.
670 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
673 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
674 to avoid compiler warnings.
676 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
678 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
680 * throw.c (handler_message): Print message on current error port
681 instead of default error port. (Thanks to Maciej Stachowiak.)
683 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
685 * ports.c (scm_add_to_port_table): allocate in units of
686 struct scm_port_table *, not struct scm_port_table.
687 * posix.c (scm_close_pipe): remove the port from the port table
689 Thanks to Rob Engle for both fixes.
691 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
693 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
694 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
696 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
698 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
700 * backtrace.c (display_error_body, display_backtrace_body),
701 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
702 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
703 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
704 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
707 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
708 don't receive the jmpbuf arg anylonger.
709 (scm_catch): Don't accept a #f tag.
710 (scm_throw): Check that key is a symbol.
711 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
713 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
715 * async.c (async_pending): Removed declaration.
717 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
719 * dynwind.c (scm_wind_chain): New debug function.
721 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
722 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
723 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
724 extra layer of functions around the body and handler of a thread.
725 This extra layer makes sure that the handler is called in the
726 dynamic context of the surround (= empty dynwind list), but under
727 the *dynamic root* of the body. We can not use the dynamic root
728 of the surround since that root belongs to another thread => stack
729 is not handled correctly. It may seem ugly to use this extra
730 layer, but the extra cost in terms of execution time is really
731 negligible compared to the total amount of time required to create
732 a thread, and it would reduce maintainability to duplicate the
733 crucial and complicated steps performed by cwdr.
735 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
736 (SCM_ALLOW_INTS): Added thread switching code before interrupts
737 get re-enabled. The important effect of this is that interrupts
738 are blocked during thread switching so that thread data structures
739 don't risk getting messed up by an unfortunate signal.
740 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
741 seems to do more aggressive optimization which actually move
742 instructions around in these macros in a fatal way. Therefore:
743 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
744 just superstitious...)
745 (SCM_TICK): Maybe do a context switch and take care of asyncs.
746 This macro should be used instead of SCM_ASYNC_TICK since the
747 latter doesn't do context switches any more.
749 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
750 instead of SCM_ASYNC_TICK.
752 * coop.c, iselect.c: Since thread switches are now performed with
753 interrupts masked, we can't use the old mechanism of delivering
754 signals immediately when they arrive. Signals must instead be
755 delivered when the asyncs run *after* the end of the critical
756 section in scm_internal_select. But this also means after context
757 switch so that the signal will be delivered to a different thread.
758 To avoid this, I have changed the protocol of
759 coop_wait_for_runnable_thread and friends so that they are allowed
760 to return the original thread. So, if a signal arrives during
761 scm_internal_select, we won't any longer be forced do a context
762 switch, but can remain in the same thread and deliver the signal
765 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
766 scm_asyncs_pending and made it global.
768 * iselect.c: Small fixes.
770 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
771 coop_condition_variable_init, coop_condition_variable_wait,
772 coop_condition_variable_signal): Changed return type from `void'
773 to `int'. This is to adhere closer to the pthreads interface.
774 This, in turn, is part of an attempt to provide C versions of the
775 mutex and condition variable primitives which can be part of a
776 frontend to COOP or pthreads.
778 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
779 coop_condition_variable_destroy): New functions.
781 * coop-threads.c (scm_wait_condition_variable): Use
782 coop_condition_variable_wait_mutex.
784 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
785 Definitions moved to coop-defs.h.
787 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
788 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
789 scm_cond_destroy): New C interface to mutecis and cond vars.
791 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
793 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
795 * iselect.c: Now several threads can wait on the same file
796 descriptor. The behaviour is compatible with OS select: All
797 threads waiting for the fd return with the same status.
799 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
801 * coop-threads.c, threads.h (scm_spawn_thread): New function.
802 Can spawn a thread from application C code.
804 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
806 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
807 gh_doubles2scm): New functions.
809 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
811 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
812 commented-out version of gh_eval_str()
814 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
816 * socket.c (scm_bind): free soka after use.
818 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
820 * stime.c (tzvar): new variable.
821 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
822 avoid memory leaks when allocating.
824 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
826 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
829 * gc.c, tags.h: Doc fixes.
831 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
833 * eval.c (macro-eval!): Removed. This function was a design bug.
834 It allowed memoized code to leak out to the scheme level. Most
835 things that you could do with `macro-eval!' can be done with
838 1997-12-20 Tim Pierce <twp@skepsis.com>
840 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
841 scm_fgets now depends on ftell(3) to know how many bytes were
844 1997-12-15 Tim Pierce <twp@skepsis.com>
846 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
847 dealing with strings.
849 1997-12-13 Tim Pierce <twp@skepsis.com>
851 Make %read-line more suitable for implementing read-line efficiently.
852 * ioext.c (scm_read_line): Strip the terminating newline from a
853 string, and return a cons of the string and its terminator.
855 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
856 of the string that is read is stored in this memory location.
857 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
858 * genio.c, genio.h (scm_do_read_line): Update caller.
859 * ports.h (scm_ptobfuns): Update typedef.
860 * fports.c (scm_fptob, scm_pipob): Update struct.
862 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
864 * filesys.c (set_element): Return file descriptor.
865 (fill_select_type): Return the highest file descriptor.
866 (scm_select): Tell select about the highest file descriptor. On
867 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
868 Therefore the extra overhead for calculating the maximum fd seems
869 to be more than compensated. Is this correct? In any case,
870 scm_internal_select will be much faster with this info.
871 (scm_select, fill_select_type, set_element): Don't accept any kind
872 of object in the file descriptor list or vector.
874 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
876 * iselect.c (finalize_fd_sets): Bugfix.
878 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
880 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
881 when using scm_internal_select (since we might switch to another
884 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
886 * simpos.c (scm_system): always define: use sysmissing if not
887 available. Check for HAVE_SYSTEM instead of _Windows (does
888 Windows lack system or does it have an unusable one?).
889 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
890 Let the argument be optional: if not supplied, call system(NULL).
892 * ports.c (scm_close_port): relax the type check from OPPORTP to
893 PORTP; closing a closed port is allowed.
895 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
897 * fports.c (scm_fgets): Return if the last char in a chunk is
898 newline. When fgets returns a string whose length is `size-1', it
899 is ambiguous whether a whole line was retrieved, so we must check
900 explicitly whether a line terminator is present.
902 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
904 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
905 before taking the CDR. (Thanks to Harald Meland.)
907 * filesys.c (scm_stat): Slightly optimized.
909 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
911 * ports.c (scm_close_port): Make sure the port is open before
914 * guile-snarf.in: Pass args through to gcc in a way that preserves
915 whitespace boundaries. (Thanks to Greg Badros.)
917 1997-12-02 Tim Pierce <twp@skepsis.com>
919 * stacks.c (scm_frame_procedure): Reverse the logic in the return
920 statement. (Thanks to Doug Evans for pointing this out.)
922 1997-12-01 Tim Pierce <twp@skepsis.com>
924 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
926 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
928 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
929 errno macro expansion of this field name. (errno is a C
930 preprocessor macro on some systems.)
932 1997-11-29 Tim Pierce <twp@skepsis.com>
934 * iselect.c: Doc fix.
936 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
938 * init.c (scm_start_stack): Removed initialization of
939 scm_the_last_stack_var.
941 * backtrace.h: Declare scm_the_last_stack_var.
943 * backtrace.c: Define scm_the_last_stack_var.
945 * root.c (mark_root): Don't mark the_last_stack_var.
947 * root.h (scm_root_state): Removed the_last_stack_var.
949 * throw.c: Added #include "fluids.h"
950 (ss_handler): `the-last-stack' is now a fluid.
952 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
953 --> the_last_stack_fluid.
955 * backtrace.c: Added #include "fluids.h"
956 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
957 (scm_backtrace): `the-last-stack' is now a fluid.
959 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
960 after scm_init_fluids.
962 1997-11-28 Tim Pierce <twp@skepsis.com>
964 * iselect.c: #ifdef USE_THREADS around thread-related includes.
966 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
967 DLSYM_ADDS_USCORE to decide whether to add an underscore.
969 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
971 * iselect.c (coop_next_runnable_thread,
972 coop_wait_for_runnable_thread): Disable interrupts so that no
973 async is executed before a potential error_revive.
974 (scm_internal_select): Disable interrupts during the parts of the
975 code which manipulate the sleep queue and the file descriptors.
977 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
979 * Makefile.am: Added iselect.c and iselect.h.
981 * coop.c (coop_qinit): Initialize fields used by
983 (coop_qget, coop_qget, coop_tmp_queue): Made global.
984 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
985 replacement in iselect.c.
986 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
987 coop_join): If GUILE_ISELECT enabled, use
988 coop_wait_for_runnable_thread instead of
989 coop_next_runnable_thread.
990 (usleep, sleep): New replacements for system functions if
991 GUILE_ISELECT is enabled.
993 * coop-threads.h: Declare coop_wait_for_runnable_thread.
995 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
997 * filesys.c: Added #include "iselect.h". Moved FD-macros to
998 iselect.h. Implement Scheme level `select' using
999 scm_internal_select. (See NEWS.)
1001 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1003 * init.c: Call scm_init_iselect.
1005 * iselect.h, iselect.c: New files. Implements
1006 scm_internal_select. (See NEWS.)
1008 1997-11-27 Tim Pierce <twp@skepsis.com>
1010 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1011 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1012 and scm_must_free, since ultimately the string returned will be copied
1013 by scm_makfrom0str anyway. Also, read any characters that may have
1014 been pushed onto the port with scm_ungetc.
1015 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1016 * ioext.c (scm_read_line): Free string after Guilifying it.
1017 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
1019 1997-11-26 Anthony Green <green@hoser.cygnus.com>
1021 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
1023 * gh.h: Safely wrap prototypes for c++ usage.
1025 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1027 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1028 gh_repl (argc, argv).
1030 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1032 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1033 and to invoke scm_shell().
1034 (gh_launch_pad): took out the loading of boot-9.scm from here,
1035 since it is probably best to let the user control that. In fact,
1036 gh_repl() now invokes scm_shell() which does that.
1038 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1040 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
1043 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
1045 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
1046 yesterday's underscore patch. (Thanks to Marius Vollmer for
1049 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
1051 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
1052 DLSYM_ADDS_USCORE is not defined.
1054 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
1056 * gh_data.c (gh_uniform_vector_length):
1057 (gh_uniform_vector_ref): started implementing the uniform types in
1060 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1062 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1063 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1065 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1067 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1068 configure.in was changed).

1072 * Makefile.am (modinclude_HEADERS): Include readline.h here.
1073 * Makefile.in: Regenerated.
1075 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1077 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1078 OPORT is an `open' port, not an output port.
1080 * filesys.c (scm_close, set_element, get_element, scm_chown,
1081 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
1082 SCM_COERCE_OUTPORT to cope with the printstate/port magic.

1085 scm_port_column, scm_set_port_column_x, scm_port_filename,
1086 scm_set_port_filename_x, scm_port_mode,
1087 scm_close_all_ports_except, scm_set_current_output_port,
1088 scm_set_current_error_port): Likewise
1089 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1090 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
1092 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
1093 * backtrace.c (display_backtrace_body): Likewise
1094 * fports (scm_setvbuf): Likewise
1095 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

1098 * unif.c (scm_uniform_array_write): Likewise
1100 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
1102 Minor problems with substring-related tag changes.
1103 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1104 exactly what we want to leave in to detect substrings.
1105 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1106 * tags.h: Fix diagrams and comments describing the S tag bit;
1107 remove vestigial remarks about the D tag bit.
1108 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1109 * strings.c: Formatting tweaks.
1111 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1112 variable first; then SCHEME_LOAD_PATH, with a warning message.
1113 (scm_parse_path): New function.
1114 * script.c: Doc fixes.
1116 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1118 Readline support, from Daniel Risacher.
1119 * readline.c, readline.h: New files.
1120 * init.c: #include "readline.h".
1121 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1122 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1123 * Makefile.in: Regenerated.
1124 * scmconfig.h.in: Regenerated, after change to ../configure.
1126 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1128 * gh.h: gh_vector_set -> gh_vector_set_x
1130 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1132 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1133 with the ! -> _x mapping when going from Scheme to C.
1135 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1137 * gh.h (gh_reverse):
1145 (gh_assoc): added these gh_ functions implemented as macros.
1147 * gh_predicates.c (gh_null_p):
1148 (gh_string_equal_p): added these two missing predicates.
1150 * gh_list.c (gh_append):
1155 (gh_set_cdr_x): added these routines as I go through and try to
1156 complete the picture R4RS functions that should be mirrored in the
1159 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1161 * tags.h (scm_tc7_substring): Changed the comment and code to
1162 conform with the changes below. Folks! We have suddenly two new
1163 free tc7 codes!!! Jummy, jummy!
1165 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1167 * Makefile.in: Rebuilt.
1168 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
1170 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
1171 * unif.c (scm_vector_set_length_x): Don't handle multibyte

1181 * gscm.c (gscm_run_scm): Don't init mbstrings module.
1182 * gc.c (scm_gc_mark): Don't handle mbstrings.
1183 (scm_gc_sweep): Likewise.
1184 * eval.c (SCM_CEVAL): Don't handle mbstrings.

1187 (SCM_TYP7D): Removed.
1188 (scm_tc7_mb_string): Removed.
1189 (scm_tc7_mb_substring): Removed.
1190 * print.c (scm_iprin1): Handle char printing directly. Don't
1192 Don't include "mbstrings.h".
1193 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
1194 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1196 Don't include "mbstrings.h".
1197 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1198 (SCM_SYMBOL_SLOTS): Define as 4.
1199 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
1200 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
1201 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,

1220 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
1221 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
1223 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1225 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1227 * gh_test_c.c (c_vector_test): some improvements on the vector
1230 * gh.h (gh_vector): this used to exist but do the wrong thing.
1231 Now it (almost) does the right thing, though it takes a list
1232 instead of the individual arguments. I need to see how it could
1234 (gh_list_to_vector): added this function as a macro. Corresponds
1235 to Scheme's (list->vector ...).
1236 (gh_vector_to_list): added this function as a macro. Corresponds
1237 to Scheme's (vector->list ...).
1239 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1240 gh_vector_ref, so that it resembles the Scheme routines more.
1241 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1242 resembles the Scheme routines more.
1243 (gh_make_vector): this used to be (stupidly) called gh_vector().
1244 This is the right name, since it does the same thing as the Scheme
1245 (make-vector ...) procedure.
1247 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1249 * ports.h: #include "libguile/print.h"
1251 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
1252 Some indentation fixes.
1254 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1255 longer a user field; New field: class_flags.
1257 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
1259 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
1261 * gh_data.c (gh_bool2scm): new function which replaces
1262 gh_int2scmb(), which is now tagged as obsolete.
1264 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1266 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1267 macros should by convention not test for NIMPness.)
1268 (SCM_COERCE_OPORT): Adjust indentation.
1270 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1271 SCM_NIMP test before SCM_PRINT_STATE_P.
1273 * struct.c, struct.h, gc.c: Renamed:
1274 scm_struct_i_layout --> scm_vtable_index_layout
1275 scm_struct_i_vcell --> scm_vtable_index_vcell
1276 scm_struct_i_vtable --> scm_vtable_index_vtable
1277 scm_struct_i_printer --> scm_vtable_index_printer
1278 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1280 * struct.c (scm_print_struct): Use new printer slot; Default
1281 printing: Also output hex code of vtable so that type identity
1282 will be indicated as well.
1283 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1284 Removed struct_printer_var; Removed struct-vtable-offset;
1285 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1286 vtable-offset-user): New constants.
1288 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1289 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1290 If this slot contains a procedure, use that to print structures of
1291 the type represented by this vtable.
1293 * print.c (scm_iprin1): Don't print arguments of macro
1294 transformers. (They are always: exp env.); Bugfix: Unmemoize
1295 transformer source with correct environment.
1297 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1299 Streamlining of call-with-dynamic-root:
1301 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1302 there is now only one catch.
1303 (cwdr_outer_body): Removed.
1304 (cwdr_handler): New function.
1305 (scm_internal_cwdr): New function to perform the function of cwdr
1306 but take args that are more useful to C code. Also, the handler
1307 is now invoked *outside* of the new dynamic root, like the docs
1308 say. We no longer have to catch absolutely all errors, the caller
1309 is responsible for using a handler that does not throw, if he
1311 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1312 * root.h (scm_internal_cwdr): New prototype.
1314 Even more but risky streamlining:
1316 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1317 allocation of the jumpbuf of a root continuation. The changes
1318 below are controlled by it. They are now deactivated.
1319 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1320 the JMPBUF of the scm_rootcont to NULL before returning.
1322 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1323 when they are non-NULL.
1324 (scm_gc_mark): Likewise, mark only when non-NULL.
1326 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1327 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1329 * gc.c (scm_done_malloc): New function.
1330 gc.h (scm_done_malloc): New prototype.
1332 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
1333 (struct scm_print_state) [revealed]: New field.

1335 type checking purposes.
1336 (scm_valid_oport_value_p): New prototype.
1338 * print.c (scm_valid_oport_value_p): New function to check whether
1339 a certain value is acceptable as a port argument.
1340 (scm_print_state_vtable): New variable.
1341 (scm_free_print_state): Set `revealed' field to false.
1342 (scm_iprin1): Call user supplied closure printer with
1343 scm_printer_apply. Print in the traditional way when there isn't
1344 one or when it returns #f.
1345 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1346 Accept a port/print-state pair in addition to just a port.
1347 (scm_prin1): Don't return the print_state to the pool when it has
1349 (scm_printer_apply): Set `revealed' field of print_state to true.
1350 (scm_init_print): Set scm_print_state_vtable.
1351 (print_state_fluid, print_state_fluid_num): Removed.
1353 * throw.h (scm_handle_by_proc_catching_all): New prototype
1354 throw.c (scm_handle_by_proc_catching_all): New function
1356 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1358 * Makefile.in: Regenerated with automake 1.2c.
1360 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1362 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1363 was looping endlessly.
1365 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1367 * strports.c (scm_eval_string): Don't close the port.
1369 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1370 former returns a nice normal integer. (Thanks to Daniel
1373 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1375 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1376 makefile variable as a build parameter called LIBS. The
1377 build-guile program will use this, for the time being.
1378 * Makefile.in: Regenerated.
1380 Thanks to Shiro Kawai:
1381 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1382 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1385 * Makefile.in: Regenerated with automake 1.2a.
1387 * script.c (scm_compile_shell_switches): If we hit the -c or --
1388 arguments, don't set the car of (command-line) to scm_usage_name,
1389 the prettified name of the guile executable; give it the full
1390 path, the way shells usually handle $0.
1392 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1394 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1395 Scheme-level name `array-map' and renamed `serial-array-map' to
1396 `serial-array-map!'.
1398 * backtrace.c: Introduced exception handlers which now enclose
1399 `display-error' and `display-backtrace' so that error reporting
1400 won't get into infinite loops if an error occurs during displaying
1401 of the error. This can very easily happen with user supplied
1402 print call-back routines.
1404 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1406 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1407 the names `serial-array-map' and `array-map' should be removed.)
1409 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1411 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1412 Added #include "objects.h"
1414 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1415 Add #include "feature.h".
1417 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1418 (modinclude_HEADERS): Added objects.h.
1420 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1421 This test is needed at many places in the code and should be
1422 abstracted. (Motivated by the need of this test in libguiletk.)
1424 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1425 (scm_eval_string), load.c (scm_primitive_load,
1426 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1427 Use SCM_EOF_OBJECT_P.
1429 * eval.c (scm_init_eval): Add feature `delay'.
1431 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1433 * scmhob.h: Removed.
1435 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1437 * list.h (SCM_LISTn): New macros. Make list creation in C code
1438 prettier. The idea comes from STk.
1440 * sequences.h, sequences.c, append.h, append.c: Removed. These
1441 files implemented non-R4RS operations which would encourage
1442 non-portable programming style and less easy-to-read code.
1444 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1447 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1448 sequences.h, #include append.h.
1450 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1453 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1455 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1457 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1459 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1461 * eval.c: Added #include "objects.h"
1463 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1466 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1467 adjacent smob numbers.
1469 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1471 * procprop.h: Added declaration of scm_i_inner_name.
1473 * gsubr.c: New global symbol scm_i_inner_name.
1475 * debug.c (scm_procedure_name): Try procedure property
1476 `inner-name' if `name' fails.
1478 * print.c (scm_iprin1): Use scm_macro_name.
1480 * eval.c (scm_m_define): Give names to macros as well; Only the
1481 first top-level definition gives a procedure/macro a name.
1482 Otherwise confusing names can turn up in backtraces.
1483 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1484 `name'; Give names to macros as well.
1486 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1487 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1490 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1492 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1494 (prinmacro): Removed. The code has been moved/merged into print.c
1495 in order to decrease code redundancy. We want macros to print in
1496 a way equivalent to procedures, and it would be silly to duplicate
1497 the required code. (We don't want to maintain two places.)
1498 (macrosmob): Print field is now a NULL pointer.
1500 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1501 scm_macro_transformer): New prototypes.
1502 (scm_tc16_macro): Declared.
1504 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1505 are now printed in a way equivalent to procedures.
1507 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1509 * procs.h (scm_closure_p): Added declaration.
1511 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1513 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1514 Shouldn't pass "heap" as the subr name.
1516 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1518 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1519 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1520 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1521 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1522 SCM_BOOL_T. Any non-false value is true.
1524 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1526 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1527 scm_gensym): Added prototypes.
1529 * symbols.c (scm_gensym): New function. This will speed up
1530 certain types of applications (such as macro systems) which
1531 generate lots of symbols.

1547 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1549 * Makefile.in: Regenerated, so it uses "tar", not "gtar".

1576 * list.c (scm_list_append_x): Allow non-pair as last argument.
1577 This is consistent with the R4RS append and is probably the
1578 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1580 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1582 * stime.h: prototype for scm_times.
1583 * stime.c (scm_times): new procedure.

1600 third argument is now optional.
1602 * posix.c (scm_execl, scm_execlp): make the filename argument
1603 compulsory, since omitting it causes SEGV.
1604 (scm_sync): return unspecified instead of #f.
1605 (scm_execle): new procedure.
1606 (environ_list_to_c): new procedure.
1607 (scm_environ): use environ_list_to_c. disable interrupts.
1608 (scm_convert_exec_args): take pos and subr arguments and
1609 improve error checking.
1611 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1613 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1614 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1615 argument to SCM_ASSERT. Furthermore, the name of the function
1616 should be passed as first argument when signalling
1617 SCM_WNA. (Thanks to Thomas Morgan)
1619 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1620 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1621 dispatches on the number of actual args has a default case
1622 reporting an internal error. This is a vestige from a version
1623 that mallocated a SCM vector to hold the arguments. In the
1624 current version this check is too late: if it ever happens we will
1625 have already overstepped the bounds of the array.
1627 Also, the patch [...] adds a check for too many actual arguments."
1629 mdj: Removed check for "internal programming error".
1631 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1633 * gh_io.c (gh_write): New function.
1635 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1636 throw.c (scm_internal_stack_catch): New sibling to the other catch
1637 functions. Code moved from gh_eval.c.
1638 throw.h: Added header.

1648 fold in the functionality of scm_primitive_dup.
1649 (scm_primitive_dup): deleted.
1651 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1653 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1654 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1655 ultrix are defined. Use setvbuf instead of setbuf.
1656 (scm_setvbuf): new procedure.
1657 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1658 (scm_setfileno): moved from ioext.c.

1672 (scm_init_print): Initialize them.
1673 (scm_iprin): If print_state_fluid carries a print_state, use that
1674 instead of creating a new one.
1675 (scm_printer_apply, apply_stub, struct apply_data): New
1676 definitions to help with calling printer functions written in
1678 * print.h (scm_printer_apply): New prototype.

1691 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1692 SCM_ASSERT: arg comes before pos.
1694 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1696 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1697 to a list of length zero correctly.

1721 stream has been set.
1722 (scm_duplicate_port): deleted, there's now an implementation in

1775 data. (dynl_smob): Use it.
1776 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
1777 the dynamic object data below the linking of the object to avoid
1778 memory leak when the linking code throws an error. Now the code
1779 leaks a whole dynamically linked library when must_malloc throws,
1780 but that should be much less likely.
1782 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
1784 Changes to compile under gnu-win32, from Marcus Daniels:

1822 think this is left over from the (eq? '() #f) days.
1824 * read.c (recsexpr): Give this a dummy definition if
1825 DEBUG_EXTENSIONS isn't #defined.
1827 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
1829 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

1855 turn off REG_EXTENDED.
1856 (scm_init_regex_posix): New regexp/basic symbol.
1857 (REG_BASIC): #define this if it is not already present.

1904 (cwdr_outer_body): New function, to establish the user's handler,
1905 and pass control to cwdr_inner_body.

1917 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
1918 the feeling that real thread systems will not need this...
1920 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
1922 Try to detect when people are using one version of libguile and a

1934 primitive definitions under their Scheme names.
1936 * Makefile.am (libguile_la_LDFLAGS): Update library version to
1937 1:2. Helps avoid confusion between installed and uninstalled libs.
1939 * scmconfig.h.in: Regenerated. (Needed after June 3 change to

1962 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
1964 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA

1968 * tag.c (scm_tag): Remove unreachable statement.
1969 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
1970 top of the word, it should be unsigned.
1972 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
1973 is defined, to avoid warnings; it's only used in the
1974 conflict-checking code. Which might go away anyway.
1975 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
1976 conditionals; put the label definition in an #if too, to stifle
1979 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
1980 ChangeLog-threads in the distribution.
1981 * Makefile.in: Regenerated.

1991 * load.c (scm_init_load_path): Append $(datadir)/guile to

1993 current version directory.
1995 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
1997 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
1998 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
1999 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2000 call the sysdep functions with deferred ints.
2001 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2002 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2003 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2006 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2009 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2011 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2013 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2015 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2018 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2020 * eval.c (scm_lookupcar1): New procedure to cope with a race
2021 condition during lookup (when using threads).
2022 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2023 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2026 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2028 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2029 supplied. (Change from Tim Pierce.)
2031 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2033 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2034 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2035 default and not `()'. `#f' is the canonical non-value in Scheme,
2038 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2040 * struct.c (struct_printer): New variable that holds a handle on
2041 the Scheme variable *struct-printer*. This variable can be set by
2042 Scheme code to override the printing of structures.
2043 (scm_print_struct): If struct_printer is set, call it. If it is
2044 not set, or returns #f, print the structure in the old fashion.
2045 Include "eval.h" for scm_apply.
2047 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2049 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2050 scm_struct_i_n_words to get the number of fields, not
2051 -scm_struct_n_extra_words.
2053 On the route to fancier struct printing:
2054 * struct.c (scm_print_struct): New function to print a structure.
2055 Include "genio.h" to support it. This function doesn't do
2056 anything interesting right now, but I think it should be here
2058 * struct.h: Include "print.h" and add prototype for
2060 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2061 print structures ourself.
2063 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2065 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2066 before applying the handler in case it doesn't return.
2068 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2070 * scmsigs.h, async.h: updated.
2072 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2075 * posix.c (scm_uname): interpret only negative values as an error.
2076 Solaris normally returns a positive value.
2078 * script.c (scm_compile_shell_switches): if we are not going into
2079 an interactive repl, set scm_mask_ints to zero so that asyncs can
2082 * simpos.c (scm_system): don't ignore/unignore signals around
2085 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2088 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2089 done in boot-9.scm instead.
2091 * scmsigs.c, async.c: Major rewriting of signal handling code.
2092 (scm_sigaction): new procedure.
2093 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2095 (scm_raise): return unspecified, throw error on failure.
2097 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2099 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2100 feature, to help boot-9.scm decide whether to import the regex
2103 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2105 * eval.c: Include scmconfig.h at the beginning of the file so that
2106 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2109 * regex-posix.c: #include "_scm.h" before conditionally #including
2110 <regex.h>; the former defines HAVE_REGCOMP.
2112 * regex-posix.c: #include <regex.h> conditionally, so the file is
2113 CPP'able (for dependency scanning) even on systems that don't have
2116 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2118 Add new R4RS-compliant syntax for keywords.
2119 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2120 regardless of the setting of the `keywords' read option.
2121 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2122 can be re-read no matter what the setting of the `keywords' read
2125 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2127 Add support for POSIX regular expressions.
2129 * regex-posix.c, regex-posix.h: New files. (Some code
2130 is taken liberally from rx/rgx.c in the old Guile dist.)
2132 * init.c: Include regex-posix.h.
2133 (scm_boot_guile_1): Call scm_init_regex_posix.
2135 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2136 Add regex-posix.[ch] sources.
2137 * Makefile.in: Regenerated.
2139 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2140 to do this automatically? It didn't for me, bleh.)
2142 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2144 * fports.c (print_pipe_port): New function.
2145 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2146 latter doesn't even take the right arguments.
2148 * Makefile.am: Increment shared lib revision number. I think
2149 sometimes the uninstalled Guile finds the installed shared lib;
2150 Gord says doing this might help. As things turned out, I can't
2151 say whether it does.
2152 * Makefile.in: Regenerated.
2154 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2155 passing it as the closure argument to scm_boot_guile. (Bill
2158 * ports.c (print_void_port, putc_void_port, puts_void_port,
2159 write_void_port, flush_void_port, getc_void_port, close_void_port,
2160 noop0): Use ANSI prototypes instead of K&R declarations, so the
2161 initialization of void_port_ptob gets aggressively type-checked.
2162 Fix arguments of print_void_port and write_void_port. (Bill

2196 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2198 * script.c (scm_find_executable): Use prototype-style definition
2199 here; apparently it's not quite right to have const in a prototype
2200 and then use a K&R declaration. I wonder if stuff like this will
2201 go away if we compile with -Wrequire-prototypes, or whatever that
2202 is... (Bernard URBAN)
2204 * scmhob.h: New text from Bernard URBAN.
2206 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2208 * script.c: Don't #define const on hpux. Configure takes care of
2209 this. (Thanks to Larry Schwimmer.)
2211 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2212 decide whether to #include <unistd.h>, instead of listing a bunch
2213 of systems. Don't #include stdio twice. Removed dyked-out
2214 definition of scm_find_impl_file.
2216 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2218 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2219 library version info to 1:0.
2220 * Makefile.in: Regenerated.

2226 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2227 throw.c: Update copyright years; these files have been worked on
2228 significantly in 1997, but only had copyright years for 1996.
2229 Also, change name of copyright holder on some from Mikael
2230 Djurfeldt to Free Software Foundation; he has signed papers
2231 assigning the changes to the FSF.
2233 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2234 reason not to give the user the option.
2236 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2237 Return #f on end-of-file when scanning table (i.e. when called
2238 with no arguments). Try to catch errors, when we can.
2239 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2241 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2242 external declarations. These are useful.
2244 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2246 * posix.c: don't include <sys/select.h> or define macros for
2247 select, since they were not used in this file.
2249 * filesys.c (scm_select): make the fifth parameter microseconds,
2250 not milliseconds. let the fourth parameter be either a real value
2251 or an integer or #f. The first, second and third arguments can
2252 now be vectors: the type of the corresponding return set will be
2254 (set_element, get_element): new static procedures.
2256 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2258 * strports.c (scm_eval_string): New function.
2259 (scm_eval_0str): Trivially re-implemented in terms of
2261 * strports.h (scm_eval_string): New extern decl.
2263 * net_db.c (h_errno): Add extern decl for this.
2265 * fports.c (local_pclose): New function.
2266 (scm_pipob): Use it in the initializer here.
2269 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2270 Use a meaningful error message when signalling an error. For
2271 this, scm_gethost must check h_errno rather than errno.
2273 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2275 * Makefile.in: Regenerated, using automake-1.1p.
2277 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2279 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2280 not SCM_UNSPECIFIED.
2282 * script.c (scm_compile_shell_switches): don't append (quit) if
2284 (scm_shell): call scm_exit_status and exit on the result of the
2287 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2289 Ensure that shared substrings are handled properly when passed to
2290 a system call or other foreign function. Many thanks to Tim
2292 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2293 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2294 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2295 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2297 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2298 (scm_display_error_message): use RO macros when strings may be RO.
2299 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2300 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2301 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

2305 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
2306 scm_strftime), vports.c (scm_make_soft_port): use
2307 SCM_COERCE_SUBSTR to make sure shared substrings are
2310 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2312 * error.c (scm_error): Add newline to error message.
2314 * init.c (scm_init_standard_ports): Doc fix.
2316 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2318 * dynl-shl.c: Completely replaced with new code from Bernard
2321 * script.c (scm_ice_9_already_loaded): New variable.
2322 (scm_compile_shell_switches): Use it.
2324 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2326 * filesys.c (scm_input_waiting_p): add missing third argument to
2329 * stime.c (scm_localtime): copy the result of localtime before
2330 calling gmtime in case they share a buffer.
2331 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2334 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2336 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2338 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2340 * Makefile.am (check-local): New target, which causes 'make check'
2341 to run gh_test_c and gh_test_repl, with some trivial input.
2342 * Makefile.in: Rgnrtd.
2344 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2346 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2349 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2351 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2352 sure how this was supposed to work.
2353 (scm_async_click): don't send SCM_TICK_SIGNAL.
2354 (scm_init_async): don't initialize %tick-thunk.
2356 * the following change doesn't affect the Scheme interface:
2357 gc-thunk is called at the end of garbage collection. however it's
2358 no longer implemented by pretending it's a signal.
2360 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2361 system async corresponding to scm_gc_thunk.
2362 * async.h: declare scm_gc_async.
2363 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2364 gc-thunk directly, instead of going through a signal handler.
2365 (scm_gc_async): new variable, points to the GC system-async.
2366 (scm_init_async): save the GC async as scm_gc_async instead
2367 of using system_signal_asyncs.
2368 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2370 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2372 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2373 Don't screw up if we're interrupted.
2374 * Makefile.in: Regeneradet.
2376 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2378 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2380 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2381 we're not using AM_INIT_GUILE_MODULE any more.
2382 * Makefile.in: Reneregated.
2384 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2386 Functions for finding variable bindings, grace à Tim Pierce.
2387 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2388 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2390 Get 'make dist' to work again.
2391 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2392 * Makefile.in: Regenerated, like a surry without a fringe on top.
2394 Changes for reduced Guile distribution: one configure script,
2396 * configure.in, configure: Removed.
2397 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2398 real configure script lives.
2399 * Makefile.in, scmconfig.h.in: Regenerated.
2401 * init.c: #include "script.h", to get prototype for script.c's
2404 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2406 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2407 scm_must_malloc, not raw malloc.
2409 * script.c (scm_compile_shell_switches): Dyke out debugging output
2412 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2414 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2416 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2417 system has them. Hope this is safe. Previously
2418 sys/timeb.h was included if HAVE_FTIME was defined or if
2419 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2420 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2422 * ioext.c (scm_setfileno): add missing third argument to
2423 scm_misc_error call.
2425 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2427 * eq.c (scm_equal_p): Correctly compare strings of different
2428 varieties. (Thanks to Tim Pierce.)
2430 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2432 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2433 #! block comment must occur on a line all by itself.
2435 Move most of the guts of shell command processing into libguile,
2436 so guile.c can be very small (and eventuallly auto-generated. (I
2437 mean, generated mechanically, not self-generated. Hmm.))
2438 * guile.c, script.c, script.h: New source files.
2439 * init.c (scm_boot_guile_1): Call scm_init_script.
2440 * libguile.h: #include "script.h".
2441 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2442 targets, for new executable.
2443 (libguile_la_SOURCES): Mention script.c.
2444 (modinclude_HEADERS): Add script.h.
2445 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2446 not dynamic linking is enabled. This is because we're generating
2447 executables now. Move CY_AC_WITH_THREADS call after those, so the
2448 values of cy_cv_threads_libs captures the libs chosen above.
2449 * Makefile.in, configure, aclocal.m4: Regenerated.
2451 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2452 We don't maintain this interface any more, and it just confuses
2455 * alloca.c: #include <scmconfig.h>, not <config.h>.
2456 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2457 it'll get included in disties.
2459 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2461 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2462 be distributed, because they confuse people.
2463 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2465 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2467 * configure.in: check for presence of gethostent (not present on
2468 OpenBSD by default).
2469 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2470 * configure, scmconfig.h.in: Regenerated.
2472 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2474 * backtrace.c (scm_backtrace): Split message string across
2475 newlines properly. GCC is more tolerant of this than other
2478 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2480 Merge threads directory into libguile.
2481 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2482 threads.h: New source files.

2484 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2486 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2487 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2488 coop-threads.c.cygnus, coop-threads.h.cygnus.
2489 * configure.in: If we're using threads, include threads.o in
2491 * _scm.h, libguile.h: threads.h lives in this directory now.
2492 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2493 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2494 currently used, but brought along for information's sake.
2495 * ChangeLog-threads: log from old 'threads' directory.
2496 * Makefile.in, configure: Rebuilt.
2498 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2500 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2503 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2505 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2507 Merge GH interface library into libguile.
2508 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2509 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2510 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2511 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2513 (EXTRA_libguile_la_SOURCES): ... here.
2514 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2515 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2516 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2517 New variables, describing how to build the gh test programs.
2518 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2519 build the test programs, and we probably should have been linking
2520 libguile.la against them all along, to support AIX shared libs.
2521 Add cflags for threads to CFLAGS; add libs for threads to new
2522 variable THREAD_LIBS, used in Makefile.am.
2523 * ChangeLog-gh: log from old `gh' subdirectory.
2524 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2526 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2528 * acconfig.h: Undo change of Apr 9; including the definition of
2529 PACKAGE in the guile headers conflicts with applications' own
2531 * scmconfig.h.in: Regenerated.
2533 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

2540 when PROC is receiving no arguments.
2542 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2544 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2545 have S_IFSOCK. This is the case under Ultrix.
2547 * posix.c (scm_status_exit_val, scm_status_exit_val,
2548 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2549 Ultrix versions of WIFSTOPPED, etc., which assume that their
2550 arguments are lvalues (hmm).
2552 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2554 * eval.c: Doc fixes.
2556 * throw.c: Doc fixes; rearranged.
2558 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
2560 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
2562 * acconfig.h: Added entry for PACKAGE.
2563 * scmconfig.h.in: Regenerated.
2565 Changes to work with automake-1.1n, which has better libtool support.
2566 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2567 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2569 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2571 * Makefile.in: Rebuild.
2573 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2575 * stime.c (scm_mktime): take an optional zone argument.
2576 (scm_localtime): check putenv return value.
2577 (scm_strftime, scm_strptime): moved from posix.c. move #include
2579 stime.h, posix.h: update prototypes.
2580 (bdtime2c, setzone, restorezone): new static procedures.
2581 (scm_mktime, scm_strftime): use them.
2582 (scm_strftime): don't call mktime before strftime. Use
2583 filltime for return value.
2584 (filltime): convert NULL zname to #f.
2585 (scm_strptime): return a count of characters consumed, not
2586 the remaining string.
2588 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2590 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2591 (scm_mktime): likewise.
2593 Uncomment localtime and mktime.
2595 * configure.in: add AC_STRUCT_TIMEZONE.
2597 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2599 * stime.c (scm_init_stime): don't define ticks/sec.
2600 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2601 return value problem and is still portable.)
2603 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2605 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2606 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2607 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2608 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2609 cpp_err_symbols.c): Corresponding changes.
2610 * Makefile.in: Regenerated.
2612 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2614 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2615 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2616 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2617 * putenv.c: new file, from sh-utils 1.12.
2619 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2620 since allocation isn't for Scheme objects.
2621 (scm_putenv): copy strings before placing in the environment.
2623 * stime.c (scm_current_time): throw an error if time returns -1,
2624 instead of returning #f.
2625 (scm_get_internal_real_time, scm_get_internal_real_time): use
2626 scm_long2num for return value instead of SCM_MAKINUM.
2628 * stime.h: prototypes updated.
2630 * stime.c (scm_time_in_msec): apparently unused, deleted.
2632 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2634 * configure.in: check for gettimeofday.
2636 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2637 which may be more usefully portable than a gettimeofday interface.
2639 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2641 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
2643 * Makefile.in: Regenerated.
2645 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2647 * stime.c (filltime): recovered static procedure.
2648 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2651 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2652 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2654 * posix.c (scm_mknod): split the mode argument into type and perms
2655 arguments, like the extra fields returned by stat.
2657 * fports.c (scm_pipob): set the close, free and print procedures.
2658 (scm_close_pipe): new procedure.
2660 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2661 define them in boot-9.scm
2663 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2665 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2666 wan't defined. Don't include fd.h.
2668 * Previously fd.h was regenerated whenever configure was run,
2669 forcing a couple of files to be recompiled.
2671 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2672 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2673 Check for _fileno as well as _file.
2675 * ioext.c: don't fd.h.
2676 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2679 * Change the stratigy for getting information about errno
2680 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2681 generating lists of symbols during the build process, which will
2682 not always work, include comprehensive lists in the distribution.
2683 To help keep the lists up to date, the "check_signals" and
2684 "check_errnos" make targets can be used.
2686 * configure.in: don't check for a command to extract errno codes.
2687 * Makefile.am: update file lists, remove errnos.list and errnos.c
2688 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2689 check_errnos targets.
2690 (CLEANFILES): remove errnos.c and errnos.list, add
2691 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2692 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2693 * errnos.default: deleted.
2694 * cpp_signal.c: new file.
2695 * cpp_errno.c: renamed from errnos_get.c.
2696 * cpp_err_symbols, cpp_sig_symbols: new files.
2697 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2698 * error.c (scm_init_error): #include cpp_err_symbols instead of
2700 * posix.c (scm_init_posix): don't intern signal symbols. #include
2703 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2705 * strop.c (scm_i_index): allow the lower bound to be equal to the
2706 length of the string, so a null string doesn't always give an error.
2708 * posix.h: new prototypes.
2709 * posix.c (scm_status_exit_val, scm_status_term_sig,
2710 scm_status_stop_sig): new functions, as in scsh. They break down
2711 process status values as returned by waitpid.
2713 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2715 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2716 configure doesn't know about it.
2718 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2720 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2722 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2723 which defines C variables with global linkage.
2725 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2727 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2730 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2732 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2733 has time to check why this doesn't work well with continuations.
2735 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2737 * Fix shell syntax error; some shells won't tolerate
2738 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2740 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2742 * posix.c (scm_uname): throw an error if uname fails instead
2745 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
2747 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
2750 * async.c (scm_ints_disabled): definition moved from error.c.
2752 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2754 * acconfig.h: Removed PACKAGE.
2756 * scmconfig.h.in: Regenerated.
2758 * snarf.h: g++ says it's non-portable not to specify the first
2759 argument in a varargs declaration. I introduced the first
2760 argument by using preprocessor conditionals.
2762 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
2764 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
2765 (scm_freopen): use RO string macros for filename and modes.
2766 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
2768 * posix.c (scm_getgrgid): simplify conversion of name to C string.
2769 (scm_mknod): use RO string macros for path.
2771 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
2772 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
2774 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2775 use SCM_ROSTRINGP and SCM_ROCHARS.
2777 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2779 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
2782 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
2783 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
2784 support for byte vectors.
2786 * print.c (scm_iprin1): Limit number of vector elements printed
2787 according to pstate->length.
2789 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2791 * backtrace.c (scm_display_error_message): don't segv if message
2794 * error.h: prototype for scm_error_scm.
2796 * error.c (scm_error_scm): new procedure, reimplements scm-error
2797 in C and uses scm_error.
2799 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2801 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
2802 pointer to the Scheme variable read-hash-procedures and intern it
2803 in scm_init_read. Modify scm_read_hash_extend and
2804 scm_get_hash_procedure to use the pointer.
2806 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2808 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
2809 (SCM_KEYWORD_STYLE): defined.
2811 * read.c (scm_read_opts): add a keywords option. This isn't a
2812 boolean option, in case someone wants to add support for DSSSL
2814 Setup scm_keyword_prefix symbol.
2815 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
2817 I've left keyword support disabled by default, since it doesn't
2818 seem to break the module system and it gives R4RS standard behaviour.
2819 It can be reactivated with (read-set! keywords 'prefix).
2821 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2823 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
2824 before constructing arbiter.
2826 * eval.c (scm_m_define): Bugfix: Check that the object is a
2827 closure before setting the procedure property!
2829 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
2831 * ports.c: Removed `ungetc-char-ready?'.
2833 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
2835 * read.c (scm_init_read): intitialise scm_read_hash_procedures
2836 (idea from Mikael: make it a pair so scm_permanent object only
2838 (scm_read_hash_extend): don't call scm_permanent_object.
2839 (ideas from Mikael): if chr is already in the list, replace its
2840 procedure instead of appending it again. If proc is #f, remove
2842 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
2844 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
2846 * gdbint.c (gdb_read): update scm_lreadr usage.
2848 * load.h: update prototypes.
2850 * load.c (scm_primitive_load, scm_read_and_eval_x,
2851 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
2853 * read.h: add prototype for scm_read_hash_extend. Change args for
2856 * read.c (scm_read_hash_procedures): new variable.
2857 (scm_read_hash_extend): new procedure.
2858 (scm_get_hash_procedure): new procedure.
2859 (scm_lreadr): use scm_get_hash_procedure instead of an argument
2860 for extended # processing.
2861 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
2862 scm_read_token): remove case_i, sharp arguments. Change callers.
2864 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
2866 * read.h (SCM_N_READ_OPTIONS): increase to 3.
2867 (SCM_CASE_INSENSITIVE_P): define.
2869 * read.c: add case-insensitive option to scm_read_opts.
2870 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
2871 to determine whether to convert symbol case.
2872 (default_case_i): definition removed.
2873 * read.c (scm_read_token): if case_i, downcase ic before doing
2876 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2878 * configure.in: Added configuration option `guile-debug'.
2879 Configure with --enable-guile-debug if you want a bunch of extra
2880 functions used for debugging when developing Guile.
2882 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
2884 * procs.c (make-cclo): New undocumented debugging procedure: Make
2885 compiled closure with internal procedure PROC and length LENGTH.
2886 Only compiled if GUILE_DEBUG is defined.
2888 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
2890 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
2892 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
2894 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
2895 with 3 or more args internally to the evaluator.
2897 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2899 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
2900 with 3 or more args internally to the evaluator. This is mainly
2901 because we don't want to pass entry and exit points of the
2902 debug support twice, but it also seems to increase the speed of
2903 the evaluator for such calls (e. g. (+ 1 2 3)).
2905 * backtrace.c (scm_display_application): New procedure:
2906 display-application; Set fancy printing parameters individually
2907 for different types of display (backtrace, error, application).
2908 (These should of course be customizable!)
2910 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
2911 clear the CHECK-flags.
2913 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2915 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
2917 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2919 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
2920 from pairs with a GLOC in the car.
2922 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
2923 otherwise `symbol-hash' will behave badly.
2924 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
2925 we get segmentation fault!
2927 * symbols.c: Added #include "weaks.h". New functions:
2928 `builtin-bindings' and `builtin-weak-bindings'. (These will be
2929 moved to an extraneous library when we split libguile.)
2931 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2933 * filesys.c (scm_stat): stat now takes fport arguments too as
2934 documented in the manual.
2936 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2938 * debug.c (scm_single_step): Bugfix: Call continuation with
2939 scm_call_continuation instead of throwing to it.
2941 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
2943 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
2944 argument wasn't declared to be optional.
2946 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2948 * stime.c (scm_init_stime): Add feature "current-time".
2950 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2952 * throw.h: prototype for scm_exit_status.
2953 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
2954 args to derive an exit status. Allows (quit) to work from a
2956 (scm_exit_status): new function.
2959 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2961 * eval.c (scm_deval): Removed some old code.
2962 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
2964 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
2967 * symbols.c (msymbolize): Bugfix: Must initialize property list to
2970 * procs.c: Introduce the existent C function scm_thunk_p at the
2971 Scheme level as well.
2973 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2975 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
2976 used from C to easily lookup the value of a symbol in the current
2979 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2981 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
2982 scm_init_unif in this file. This will also fix a previous problem
2985 * configure.in: Added AM_MAINTAINER_MODE
2987 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2989 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
2992 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
2994 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
2995 source files that are not always included in libguile but should
2996 have their dependencies calculated by automake. This variable is
2997 recognized by automake, no further magic is needed.
2998 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
2999 to deal exclusively with *.lo files, as it seems. The *.o files
3000 are built automatically when the corresponding *.lo file gets
3003 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3005 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3008 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3010 * unif.c (scm_array_set_x): minor change to argument error checking.
3012 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3014 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3015 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3016 They should only be included in the library at configure.in's
3018 (libguile_la_LDADD): Include the appropriate .lo files here.
3019 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3020 so we know when to build them (and their .lo bretheren).
3021 * configure.in (LIBLOBJS): New substituted variable. We let
3022 configure decide which .o files to include in LIBOBJS, and then
3023 put the corresponding list of .lo files in LIBLOBJS. The latter
3024 is what we pass to libtool.
3025 * Makefile.in, configure: regenerated.
3027 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3029 * symbols.c (scm_sysintern0): New function. Contains the core of
3030 old scm_sysintern but doesn't take a second value argument.
3031 (scm_sysintern): Now uses scm_sysintern0.
3032 (scm_sysintern_no_module_lookup): Renamed to
3033 scm_sysintern0_no_module_lookup and doesn't take a second value
3034 argument any longer.
3036 * symbols.h (scm_sysintern0: Added declaration.
3038 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3039 scm_sysintern when interning option keys. Otherwise we risk
3040 destroying the values of already interned variables.
3042 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3043 scheme-level boolean (use SCM_NFALSEP).
3045 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3047 (scm_backtrace): New function. (C version of old function from
3048 boot-9.scm) Motivation: Make it possible to display backtraces
3049 without depending on boot-9.scm. (I'm uncertain if this
3050 motivation is good enough...)
3052 * root.h (scm_root_state): Add member the_last_stack_var.
3053 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3055 * root.c (mark_root): Mark scm_the_last_stack_var.
3057 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3060 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3062 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3063 1. mark_lazy_catch didn't mark the smob.
3064 2. Both functions above have standard variants:
3065 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3066 free_lazy_catch --> scm_free0.
3068 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3070 * throw.c (scm_internal_lazy_catch): New function.
3071 (scm_lazy_catch): Rewritten to use it.
3072 (scm_ithrow): Handle the new lazy catch representation.
3073 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3074 that doesn't have a jmpbuf is a lazy catch clause.
3075 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3076 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3077 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3079 (scm_init_throw): Register the new lazy-catch smob type.
3080 * throw.h (scm_internal_lazy_catch): decl for new function.
3082 * throw.c (scm_internal_catch): Doc fixes.
3084 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3085 configure.in. Including this might cause problems if applications
3086 that link against libguile include their own copies of alloca, but
3087 if they're using autoconf, they should be adding libguile to LIBS
3088 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3089 the copy in libguile, and things will be okay. (I think.)
3091 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3093 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3095 strop.h: move prototypes too.
3097 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3099 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3102 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3103 etc. I deleted them from filesys.c long ago, but didn't
3104 notice they were here too (although ineffective since
3105 sys/stat.h wasn't included).
3107 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3109 * eval.c: Don't define alloca in GCC case. gcc will automatically
3110 use __builtin_alloca if appropriate.
3112 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3114 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3115 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3116 that values of automatic variables are preserved. See comments
3117 for safe_setjmp for details.
3119 Change from Thomas Morgan:
3120 * variable.c: Include eq.h.
3121 (var_equal): New function.
3122 (variable_smob): Use var_equal as the discriminator for variables.
3124 * throw.c (s_throw): Remove extraneous declaration.
3126 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3127 * eval.c: Add necessary CPP cruft to support that.
3128 * configure, Makefile.in, scmconfig.h.in: regenerated.
3130 Change from Thomas Morgan:
3131 * procprop.c (scm_procedure_properties): Convert the Scheme
3132 boolean returned by scm_procedure_p into a C boolean before using
3133 it as a condition for SCM_ASSERT.
3134 (scm_procedure_property): Likewise.
3136 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3137 indications of Unixness.
3140 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3142 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3144 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3146 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3147 "unknown # object" error messages.
3149 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3150 (scm_i_index) and declare it static. Add a 'direction' argument
3151 to indicate what way the search should go.
3152 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3154 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3155 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3157 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3159 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3161 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3162 to avoid clash with various scsh forks.
3164 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3166 The following two changes (ramap.c, throw.c) are motivated by the
3167 apparent unportability of forward declarations of static arrays of
3168 the form `static foo bar[];'.
3170 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3171 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3173 * throw.c (scm_throw): Moved above scm_ithrow.
3175 * options.h: Removed the extern declarations of scm_yes_sym and
3176 scm_no_sym since these are static.
3178 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3180 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3182 * Makefile.am: remove AWK=@AWK@.
3183 Add a rule for generating errnos.list.
3184 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3186 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3187 don't extract errnos, just set a variable (avoids the
3188 need to recompile error.c just because configure is run.)
3190 * unif.h: update prototypes.
3191 * unif.c (scm_uniform_array_read,write): change the offset and
3192 length arguments to start and end, for consistency.
3194 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3196 * ioext.h: update prototypes.
3197 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3198 scm_read_line_x, it's a more general procedure using an
3199 interface from scsh. read-line and read-line! are now defined
3201 Note that the new read-line trims the terminator
3202 by default, previously it was appended to the returned string. An
3203 optional argument specifies how to process the terminator (scsh
3204 compatible). For the old behaviour: (read-line port 'concat).
3205 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3206 returns a pair, but is converted to multiple values if the scsh
3209 socket.h: update prototypes.
3210 * socket.c (scm_recvfrom): for consistency with other procedures,
3211 take start and end as separate optional arguments.
3212 (scm_recv, scm_recvfrom): don't allow the second argument
3213 to be a size, only a buffer. Change the scheme names to
3214 recv! and recvfrom!. Don't return the buffer.
3216 * ioext.h, posix.h: move prototypes too.
3217 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3218 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3219 "read.h" and "unif.h".
3220 * ioext.c: include "chars.h"
3222 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3224 * dynl.c: The dynamic linking and module registration functions
3225 are now defined even when dynamic linking is not available for the
3226 host system. Some of their functionality can be done without
3227 dynamic linking; when it's really needed, they throw errors.
3229 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3231 * configure.in: Only define DYNAMIC_LINKING when one of the system
3232 dependent functions is detected.
3233 * dynl.c (scm_dynamic_func): New function to get the address of a
3234 function in a dynamic object.
3235 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3236 produced by scm_dynamic_func as the thing to call.
3238 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3240 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3241 (scm_register_module_xxx, scm_registered_modules,
3242 scm_clear_registered_modules): New functions.
3244 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3246 * symbols.c (scm_sysintern): Renamed to
3247 scm_sysintern_no_module_lookup.
3248 (scm_sysintern): New function to take the place of the old
3249 scm_sysintern. It uses the current toplevel lookup closure to give
3250 the symbol its value. This is a temporary hack to put packages
3251 like gtcltk into their own module.
3252 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3253 us whether `scm_top_level_lookup_closure_var' has been initialized
3255 * eval.c (scm_init_eval): Set it.
3257 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3259 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3260 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3262 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3264 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3265 scm_sys_dup): deleted: FD capability will be added to other
3267 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3268 scm_fd_free, fd_smob, scm_intern_fd.
3269 (scm_open): renamed from scm_sys_open. Return a port instead of
3270 an FD object. Make the mode argument optional.
3271 (scm_sys_create): deleted, it's just a special case of open.
3272 (scm_init_filesys): move interning of constants O_CREAT etc.,
3273 here (were previously using SCM_CONST_LONG macro).
3274 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3276 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3277 include "fports.h" and <stdio.h>
3278 (scm_stat, scm_select): don't support FD objects.
3280 * error.h: adjust scm_syserror_msg prototype.
3281 * error.c (scm_syserror_msg): take an extra argument for errno.
3282 Using the global value didn't always work, since it could be
3283 reset by procedure calls in the message or args arguments.
3285 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3286 I don't understand why the check was there (and what about the
3289 * strop.c (scm_string_copy): allow shared substrings to be copied.
3291 * unif.h: corresponding change to prototypes.
3292 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3293 recognize two new optional arguments: offset and length. Allow
3294 the port argument to be an integer (file descriptor, for scsh).
3295 Include <unistd.h> for "read" prototype.
3297 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3299 * socket.c: don't include filesys.h.
3301 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3303 * Makefile.am: add AWK=@AWK@ (?)
3305 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3307 Add a rule to generate errnos.c from errnos.
3308 * error.c (scm_init_error): include errnos.c.
3309 * errnos_cnvt.awk: new file, converts the list of errno codes to
3311 * errnos_get.c: new file.
3312 * errnos.default: new file, contains errnos to try if they can't
3313 be extracted from errno.h.
3314 * configure.in: if using GCC, try and extract errno codes from
3318 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3320 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3321 * Makefile.am: Made libguile into a libtool library.
3322 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3323 Set libtool_libs to indicate that libguile is a libtool library.
3324 See guile/ChangeLog for details.
3325 * .cvsignore: ignore "*.lo", the libtool library objects.
3327 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3329 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3330 use htons in getservbyport argument.
3332 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3334 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3335 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3338 * objprop.c (scm_object_property): No need to take the CDR of the
3339 value returned by scm_object_properties, since Aug 20 change.
3341 * configure.in: When checking for struct linger, #include
3342 <sys/types.h> as well as <sys/socket.h>. I've never known
3343 <sys/types.h> to cause any portability problems, and Solaris's
3344 <sys/socket.h> needs it.
3345 * configure: Rebuilt.
3347 I think the Sun compiler has chosen a perverse way to interpret
3348 ANSI declarations combined with K&R definitions. We'll
3349 appease it a little bit. But when it invades France, we fight.
3350 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3351 * print.h (scm_iprlist): Here too.
3352 * numbers.c (scm_divbigdig): Change definition to match
3353 declaration in numbers.h.
3354 * unif.c (scm_makflo): Change definition to match declaration in
3357 * init.c (scm_boot_guile): Don't return the value of
3358 scm_boot_guile_1. This function doesn't return a value;
3359 scm_boot_guile_1 doesn't return a value (or return at all).
3361 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3364 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3365 compile. I have a feeling this function is a bad idea anyway ---
3366 one should always test for features, not systems.
3368 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3369 semicolons. Only pure luck kept this from being noticed earlier.
3371 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3373 * socket.c (scm_recvfrom): Added missing semicolon.
3375 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3377 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3378 the buffer and start and end positions for scsh networking
3381 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3383 * configure.in: Revert previous change to this file; the problem
3384 is due to transient automake weirdness.
3385 * configure: Rebuilt.
3387 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3388 PLUGIN/guile.libs. configure generates the latter from the former.
3389 * Makefile.in: Rebuilt.
3391 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3392 need this if we install scripts, like guile-snarf.
3393 * configure: Rebuilt.
3395 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3397 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3399 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3401 * socket.c (scm_addr_vector): fix faulty scm_listify.
3403 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3405 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3406 style block comment is no longer considered an error.
3408 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3410 * PLUGIN/guile.libs.in: New file.
3411 * PLUGIN/guile.libs: Removed from repository.
3412 * configure.in: Create PLUGIN/guile.libs from
3413 PLUGIN/guile.libs.in. This is for including additonal libraries
3414 needed for dynamic linking.
3415 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3416 instead of PLUGIN/guile.libs.
3418 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3420 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3422 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3423 occurrences of the given element from the list, not just the
3424 first. This is how the Emacs Lisp functions behave, how the
3425 analogous Common Lisp functions behave, and (I believe) how the
3426 older Maclisp functions worked. I realize that this change may
3427 break code, but it seemed better to break it before the Guile
3430 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3431 Their prototypes were already present in gc.h, but they weren't
3433 (scm_init_storage): Initialize scm_protects.
3434 * root.c (scm_protects): New element of scm_sys_protects.
3436 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3438 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3440 * libguile.h: Added #include "libguile/net_db.h".
3442 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3443 30 change. That file is only meant for communication between the
3444 configuration process and load.c. If code linked against libguile
3445 wants to get at the paths mentioned in libpath.h, it can call
3446 functions declared in load.h.
3448 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3450 * libguile.h: Removed #include "libguile/fdsocket.h"
3452 * net_db.c: Added #include <sys/socket.h>.
3454 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3456 * filesys.c (scm_input_waiting_p): use select in preference to
3457 FIONREAD, since the latter doesn't detect EOF.
3458 Throw error if neither select nor FIONREAD available.
3460 * socket.c (scm_connect): take a port, not a fd object.
3461 (scm_fill_sockaddr): throw an error if fam is not recognised.
3462 (scm_bind): use scm_fill_sockaddr.
3463 (scm_listen): take a port, not a fd object.
3464 (scm_accept): take and return a port. return #f in the car if
3465 address can't be got
3466 (scm_sock_fd_to_port): new procedure.
3467 (scm_socket): use scm_sock_fd_to_port.
3468 (scm_addr_vector): throw error if unrecognised address type.
3469 take an extra argument with the calling procedure name.
3470 (scm_getsockname): take a port. return #f if address can't be got.
3471 (scm_getpeername): take a port. return #f if address can't be got.
3472 (scm_recvfrom): take a port. return #f for address component if can't
3474 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3475 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3477 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3479 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3480 use separate data pointers, to allow them to be designed
3481 independently and reused.
3482 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3483 Renamed from catch_body, catch_handler, and uncaught_throw; made
3485 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3487 (scm_catch): Use the above.
3488 (scm_throw): Don't bother printing a message for an uncaught
3489 throw; we establish a default handler in init.
3490 * throw.h (scm_internal_catch): Prototype updated.
3491 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3493 (struct scm_body_thunk_data): New structure, used as data
3494 argument to scm_body_thunk.
3495 * init.c (struct main_func_closure): New structure, packaging up
3496 the data to pass to the user's main function.
3497 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3498 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3499 scm_internal_catch to establish a catch-all handler, using
3500 scm_handle_by_message. This replaces the special-case code in
3502 (invoke_main_func): Body function for scm_internal_catch; invoke
3503 the user's main function, using the main_func_closure pointer to
3504 decide what to pass it.
3505 * root.c (struct cwdr_body_data): Remove handler_proc member.
3506 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3507 (cwdr_handler): Removed.
3509 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3511 * socket.h (SCM_P): update bind prototype.
3512 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3513 include "feature.h".
3514 (scm_socket): return a port, not a file descriptor object.
3515 include "fports.h" and <unistd.h>
3516 (scm_bind): take a port, not a file descriptor object.
3517 take an extra argument for address args.
3519 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3520 INADDR_NONE, INADDR_LOOPBACK.
3522 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3524 * init.c: include net_db.h and not fdsocket.h.
3525 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3527 * Makefile.am: corresponding changes.
3528 * socket.h: renamed from fdsocket.h, fix names.
3529 * net_db.h: renamed from socket.h, fix names.
3530 * socket.c: renamed from fdsocket.c.
3531 remove _sys from procedure names.
3532 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3533 add "socket" to features list.
3534 * net_db.c: renamed from socket.c.
3535 remove _sys from procedure names.
3536 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3537 add "net-db" to features list.
3538 include "net_db.h". don't include <sys/socket.h> or
3541 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3543 * tags.h (scm_tags): Removed comma at end of last enumerator.
3545 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3547 Don't use GCC extensions to allocate space for debugging frames.
3548 (Here he goes again! Why do we put up with this?!)
3549 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3550 an scm_debug_info structure, not an in-line array of them. Add
3551 'info' member, to say how many vect elements we've used, for eval
3553 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3554 a new variable debug_info_end to mark the end of vect, instead of
3555 the address of the 'info' pointer itself.
3556 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3557 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3558 (SCM_APPLY): Explicitly allocate space for debug.vect.
3559 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3560 * stacks.c: Adjusted for new debug frame structure.
3561 (RELOC_INFO, RELOC_FRAME): New macros.
3562 (stack_depth, read_frames): Use them, and new scm_debug_frame
3563 element 'info', instead of magically knowing that eval frames have
3564 an info pointer sitting after vect.
3565 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3567 (scm_init_stacks): Formatting tweaks.
3569 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3571 Give GCC more control flow information, so it can be sure that
3572 variables aren't used uninitialized.
3573 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3574 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3575 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3576 scm_misc_error): Tell GCC that these functions never return.
3577 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3578 out the field type, call abort if SCM_ASSERT returns, to placate
3580 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3581 scm_wta ever returns. We can't handle this case anyway, and this
3582 gives the optimizer more information.
3583 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3584 scm_wta ever returns.
3586 In some cases, the code is fine, but GCC isn't smart enough to
3587 figure that out; this usually happens when one variable is only
3588 initialized and used when a particular condition holds true, and
3589 we know that condition will never change within a given invocation
3590 of the function. In this case, we simply initialize the variables
3591 to placate the compiler, hopefully to a value which will cause a
3592 crash if it is ever actually used.
3593 * print.c (scm_iprin1): Initialize mw_pos.
3594 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3595 * throw.c (scm_ithrow): Initialize dynpair.
3596 * unif.c (scm_uniform_vector_ref): Initialize cra.
3597 * struct.c (init_struct): Initialize prot.
3598 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3600 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3601 if EXPR contains no expressions.
3603 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3605 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3606 cause an infinite loop (???). So much for the algebraic
3607 equivalency of variable-sized arrays and alloca...
3609 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3611 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3612 a SCM boolean, not a C boolean.
3614 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3616 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3617 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3618 rules for raising scm_mtrigger. Previously, unfortunate but not
3619 unlikely circumstances could result in almost constant invokation
3620 of the gc. Now, this situations should be less likely, but they
3621 are not prevented completely.
3623 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3625 * numbers.c (scm_fuck): Procedure removed; looks like old test
3627 * numbers.h: Prototype removed.
3629 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3631 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3632 array to a pointer, to match my Nov 21 change in eval.c.
3634 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3636 * libguile.h: Added #include "libguile/backtrace.h", #include
3637 "libguile/stacks.h".
3639 * strings.c (scm_string scm_make_string scm_string_ref
3640 scm_string_set_x scm_string_equal_p scm_string_append):
3641 Bugfix according to scm patch from Aubrey Jaffer:
3642 Corrected long-standing
3643 (not (eqv? (integer->char 128)
3644 (string-ref (make-string 1 (integer->char 128)) 0)))
3645 bug found by John Kozak <jk@noontide.demon.co.uk>.
3647 * strports.c, strports.h: Make scm_eval_0str return the value of
3648 the last expression evaluated (previously, it returned void).
3650 * strports.c, strports.h: New function: scm_read_0str. Does what
3653 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3655 * simpos.c (scm_getenv): return #f if string can't be found in the
3656 environment instead of throwing an exception, for compatibility
3657 with numerous other systems.
3659 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3661 * Makefile.am (.c.x): Use guile-snarf.
3662 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3664 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3666 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3668 * backtrace.c (scm_display_error_message): Made non-static, and
3669 renamed from display_error_message.
3670 * backtrace.h (scm_display_error_message): Added extern decl.
3671 * throw.c (uncaught_throw): Use it to display the error message.
3673 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3675 * inet_aton.c: Use #if 0, not #ifdef 0.
3677 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3679 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3680 to convert the returned value.
3681 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3682 the offset argument.
3684 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3686 Add new interface to catch/throw, usable from C as well as
3688 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3689 (scm_internal_catch): New function, replaces...
3690 (scm_catch_apply): Deleted.
3691 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3692 mechanism which is a bit more code, but can be used nicely from C
3693 and implement the Scheme semantics as well.
3694 (scm_internal_catch): This is the replacement; it's named after
3695 the analogous function in Emacs.
3696 (scm_catch): Reimplemented in terms of the above.
3697 (struct catch_body_data, catch_body, catch_handler): New
3698 functions, used by scm_catch.
3699 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3700 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3701 support for new cwdr.
3703 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3706 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3708 * acconfig.h: Added DYNAMIC_LINKING symbol.
3709 * configure.in: Add option and checks for dynamic linking.
3710 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3711 dynl.h: New files for dynamic linking support.
3712 * Makefile.am (libguile_a_SOURCES):
3714 (modinclude_HEADERS): Added "dynl.h".
3715 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3717 * init.c (scm_boot_guile_1): Call
3718 scm_init_dynamic_linking to initialize dynamic linking support.
3720 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3722 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3723 (as we Schemers say). It needs to be global, so that I can tweak
3724 it for the proper operation of unexec.
3725 (scm_boot_guile_1_live): New variable, see above.
3727 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3729 * guile-snarf.sh: Removed.
3730 * PLUGIN/guile.libs: Added dependency for -lm.
3731 * acinclude.m4: Renamed from aclocal.m4.
3732 * PLUGIN/greet: Removed.
3733 * Makefile.am, aclocal.m4: New files.
3734 * configure.in: Updated for Automake.
3736 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3738 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3739 and not top_level_lookup_thunk_var.
3741 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3743 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3745 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3747 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3748 Scheme function, instead of syntax. Single argument is now a
3751 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3753 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3754 scm_ra_divide): Properly terminate statements passed as arguments
3755 to IVDEP macros. (Thanks to Bernard Urban.)
3757 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
3758 with non-constant sizes. (Thanks to Bernard Urban.)
3760 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3762 It's an "eval closure", not an "eval thunk." A thunk is a
3763 function of no arguments.
3764 * root.h (struct scm_root_state): Renamed
3765 top_level_lookup_closure_var from top_level_lookup_thunk_var.
3766 (scm_top_level_lookup_closure_var): Renamed from
3767 scm_top_level_lookup_thunk_var.
3768 * root.c (mark_root): Uses changed.
3769 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
3770 * init.c (scm_start_stack): Uses changed.
3771 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
3772 Change scheme-visible name to *top-level-lookup-closure* from
3773 *top-level-lookup-thunk*.
3775 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
3777 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
3778 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
3780 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
3782 * gc.c (struct scm_heap_seg_data): Doc fixes.
3784 * gc.c (scm_gc_sweep): Empty all segments' freelists before
3785 sweeping. Then, prepend each segment's free cells to its
3786 freelist, rather than wiping out the old value. (Thanks to Marius
3789 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
3790 scm_check_freelist, scm_debug_newcell): New functions and
3791 variables, for debugging freelist problems.
3792 * pairs.h (SCM_NEWCELL): New debugging version added.
3793 * gc.h (scm_debug_newcell): Added extern declaration, used by
3794 debugging version of SCM_NEWCELL.
3796 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3798 On some systems <libc.h> conflicts with <unistd.h>, and should not
3799 be #included at all.
3800 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
3801 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
3802 * configure.in: Call it.
3803 * posix.c, filesys.c: Use its results to decide whether or not to
3805 * configure, scmconfig.h.in: Rebuilt with autoconf and
3808 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3810 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
3811 pointer to the stdio stream before calling scm_setbuf0, so the
3812 latter will be able to retrieve it. I'm surprised this didn't
3813 segfault earlier. (Thanks to Christopher Lee.)
3815 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3817 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
3820 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3822 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
3823 number of stack narrowing specifier pairs. The first specifier in
3824 a pair controls inner border, the second the outer border. A
3825 number means cut that number of frames, a procedure object means
3826 cut until that object is found in operator position in a frame.
3828 * root.c (cwdr): Bugfix.
3830 * read.c: Recording of positions disabled by default.
3832 * procs.c (scm_closure_p): New function.
3834 * posix.c (scm_tmpnam): New function.
3836 * load.c: Added #include "throw.h".
3837 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
3840 * load.c, load.h (scm_read_and_eval_x): New function.
3842 * eval.c: Renamed debug option "deval" to "debug".
3844 (scm_eval_x): `eval!' is no longer accessible from the scheme
3845 level. Motivation: We can't allow operations which introduce
3846 glocs into the scheme level. Guile's type system can't handle
3847 these as data. Use `eval' or `read-and-eval!' as replacement.
3849 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
3850 SCM_CONSP since this is a macro!; Set vframe.prev to
3851 scm_last_debug_frame instead of 0. In this way we can look
3852 "above" the virtual start stack frame if we wish.
3853 (scm_debug_hang): New function: Useful for debugging Guile in
3854 certain tricky situations. Will probably be removed later...
3856 * debug.h: Changed semantics of debug option "backtrace". This
3857 option now only indicates whether we want automatic backtrace at
3860 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3862 * ports.c: #include "filesys.h"
3863 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
3865 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
3866 Motivation: This is system specific code which is related to file
3867 I/O. It also may use select. Added code by Gary Houston to
3868 detect presence of character in stdio buffers.
3870 * libguile.h: #include "libguile/libpath.h"
3872 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
3873 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
3874 SCM_SITE_DIR; Install libpath.h among the other include files.
3876 * load.c, load.h (scm_sys_package_data_dir): New function.
3878 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3880 * stacks.h: Bugfix: Don't use tail-array length field as stack
3881 length field! This screwed GC.
3883 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3885 * _scm.h: Added #ifndef around definition of macros min and max.
3887 * __scm.h: Added hooks for threads to plugin to in ints protection
3888 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
3889 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
3890 the main code in these macros duplicated and spread over multiple
3891 files. Renamed SCM_THREADS_SWITCHING_CODE ->
3892 SCM_THREAD_SWITCHING_CODE.
3894 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
3896 * snarf.h: New file.
3897 * guile-snarf.sh: New file.
3898 * Makefile.in (inner_h_files): Added snarf.h
3899 (ancillary, install, uninstall, distclean): Added actions for
3901 (.c.x): Use guile-snarf.
3902 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
3903 (gen_c_files): Note that these depend on guile-snarf.
3904 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
3905 now in "snarf.h". Added #include "snarf.h" to get them.
3906 * libguile.h: Added #include "snarf.h".
3907 (Patches applied and tweaked by Jim Blandy.)
3909 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3911 * socket.c: Use K&R style declaration for 'close'; the GNU coding
3912 standards suggest against providing prototypes for system
3913 functions. Thanks to Greg Troxel.
3915 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3917 * strports.c (scm_eval_0str): New function.
3918 #include "read.h", to get prototype for scm_read.
3919 * Makefile.in (strports.o): Update dependencies.
3920 * strports.h: New prototype.
3922 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
3923 scheme name from "int?" to "integer?". It seems to do the job.
3924 * numbers.h: Rename prototype too.
3925 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
3928 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
3929 scm_num_eq_p): Rename these according to R4RS conventions: call
3930 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
3931 to making libguile R4RS compliant without ice-9...
3933 * load.c (scm_sys_search_load_path): Search for files under all
3934 extensions listed in the %load-extensions variable. If FILENAME
3935 is absolute, return it unchanged, without searching the load path.
3936 (scm_loc_load_extensions): New variable, pointing to
3937 %load-extensions' value cell.
3938 (scm_init_load): Initialize it, and the value it points to.
3939 (scm_primitive_load_path): Improve error reporting.
3941 * load.c (scm_loc_load_hook): New variable, pointing to value cell
3942 of new Scheme variable %load-hook.
3943 (scm_primitive_load): Apply %load-hook to filename.
3945 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
3947 * configure.in: add tests for figuring out whether buffered data
3948 is available in a FILE structure, which is needed by char-ready.
3950 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
3953 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
3954 exceptions using misc_error instead of syserror. It seems a bit
3955 odd to throw an exception if a string can't be found in the
3956 environment, but it's consistent with open-file, stat etc.
3957 (simpos.h): remove sys_ from getenv.
3959 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
3960 occurs, throw an error instead of returning errno. Return value
3962 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
3964 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
3966 * filesys.c (scm_stat2scm): derive file type and permissions from
3967 the stat mode and append them to the returned vector.
3968 There isn't much overhead in doing this and it avoids the need to
3969 work with S_IRUSR et al. in Scheme.
3970 Define symbols scm_sym_regular etc.
3971 (scm_init_filesys): don't intern S_IRUSR etc.
3973 * load.c: change s_try_load and s_try_load_path to s_primitive_load
3974 and s_primitive_load_path.
3976 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
3978 * error.h: don't declare error symbols. prototype for scm_misc_error.
3980 * stackchk.c (scm_stack_overflow_key): defined here instead of in
3983 * error.c: use SCM_SYMBOL to set up error keys.
3984 scm_misc_error: new procedure.
3986 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3988 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
3989 between `#!' and `!#' is ignored.
3990 (skip_scsh_block_comment): New function.
3992 * feature.c (scm_set_program_arguments): New argument, FIRST.
3993 * feature.h: Update prototype.
3994 * init.c (scm_boot_guile_1): Pass new argument to
3995 scm_set_program_arguments.
3997 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3999 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4000 (scm_boot_guile): Call scm_set_program_arguments here, later than
4001 the old initialization.
4003 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4004 initialization procedure.
4005 - Delete in, out, err arguments; there are other perfectly good
4006 ways to override these when desired.
4007 - Delete result argument; this function shouldn't ever return.
4008 - Rename init_func argument to main_func, for less confusion.
4009 - Delete boot_cmd argument; main_func is more general.
4010 -Add 'closure' argument, to help people pass data to main_func
4011 without resorting to global variables.
4012 - Abort if reentered; don't bother returning an error code.
4013 - Call scm_init_standard_ports to set up the default/current
4014 standard ports; no need to pass them to scm_start_stack.
4015 - Remove code to evaluate the boot_cmd, and start the repl; let
4016 the user do something like that in main_func if they want.
4017 - Remove code to package up a return value; main_func can do any
4019 - Call exit (0), instead of returning.
4020 (scm_start_stack): Don't initialize the I/O ports here; that's
4021 weird. Delete in, out, err arguments. Move guts to
4022 scm_init_standard_ports, scm_stdio_to_port.
4023 (scm_init_standard_ports): New function, to set up current and
4024 default standard ports.
4025 (scm_start_stack, scm_restart_stack): Make these static.
4026 * init.h (scm_boot_guile): Adjust declaration.
4027 (scm_start_stack, scm_restart_stack): Remove externally
4028 visible declarations for these.
4029 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4031 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4032 written out several times in scm_start_stack.
4033 * fports.h: New declaration for the above.
4035 * feature.c (scm_set_program_arguments): New function.
4036 * feature.h: New declaration for the above.
4038 * ports.c: Formatting tweak.
4040 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4042 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4043 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4044 for obtaining the address of a car or cdr field. Motivation:
4045 &SCM_CXR make assumptions about the internal structure of the
4048 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4049 Motivation: see SCM_CXRLOC.
4051 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4052 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4053 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4054 Motivation: Safer use. Some other macros are defined in terms of
4055 these operations. If these are defined using the SCM_SETCXR
4056 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4057 to inefficiency and an <e1> with side-effects could potentially
4058 break. Also, these particular operations are heavily utilized in
4059 the garbage collector. In unoptimized code there will be a
4062 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4063 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4064 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4065 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4066 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4067 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4068 vports.c: Cleaned up use of pairs: Don't make any special
4069 assumptions about the internal structure of selectors and
4070 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4071 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4072 (Among other things, this change makes it easier to build Guile
4073 with certain compilers which have problems with casted lvalues.)
4075 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4077 * stacks.c: Improve selection of relevant stack frames when making
4078 a stack object. Introduce one level of indirection in the stack
4079 object to make it possible to "narrow" to a certain region of the
4080 stack. This facilitates making use of more clever algorithms (not
4081 implemented) for selecting relevant frames and gives a cleaner
4082 design since selection of frames can be done independently of
4083 extraction of frames from the real stack.
4084 (scm_stack_id): Also take #t as argument which means look at
4087 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4088 Turn n_tail into an integer directly representing current number
4089 of frames in stack. Add field tail.
4091 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4093 * debug.c (scm_make_memoized): Made it available at scheme level.
4094 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4095 SCM_NIMP before applying heavier predicates in argument checking.
4096 (scm_local_eval): Also take memoized object as argument.
4098 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4099 aren't created with zero length, but should such a strange
4100 creature suddenly turn up...
4102 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4104 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4105 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4107 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4109 * variable.c (scm_make_variable): Make the name hint optional, as
4111 (anonymous_variable_sym): Renamed from variable_sym. All uses
4114 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4115 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4116 of scm_primitive_load_path was also changed to
4117 "primitive-load-path", from "%try-load-path". Callers changed.
4118 We'd like to respect the convention that a function named
4119 "try-mumble" should behave just like the function called "mumble",
4120 but return #f instead of signalling some error.
4121 * load.h: Rename prototypes.
4123 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4125 * print.c (make_print_state, grow_print_state), print.h: Modified
4126 the print state representation: Don't use a tail array for
4127 recording of circular references. Resizing of the print state
4128 structure invalidates the print state pointer. To avoid passing
4129 around an indirect print state reference to all printing
4130 functions, we instead let the print state reference a resizable
4133 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4135 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4136 Don't crash when passed an improper list terminated by a
4137 non-immediate value.
4139 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4141 Allocate data for structures on an eight-byte boundary, as
4142 required by the tagging system.
4143 * struct.c (alloc_struct): New function.
4144 (scm_make_struct, scm_make_vtable_vtable): Call it.
4145 * struct.h (scm_struct_n_extra_words): Bump to 3.
4146 (scm_struct_i_ptr): New "field".
4147 * gc.c (scm_gc_sweep): When we need to free the data, use the
4148 information stored by alloc_struct to find the beginning of the
4149 block allocated to the structure, so we can free it.
4151 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4153 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4156 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4157 (scm_debug_info): New member: id.
4159 * stacks.c: Stacks are now represented as structs; Stacks have an
4160 id given to them by `start-stack'.
4161 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4163 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4164 Changed stack representation.
4166 * debug.c (scm_procedure_name): Try procedure property `name' for
4167 compiled closures aswell.
4169 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4171 * eval.c: scm_i_name moved to gsubr.c
4172 (scm_m_define): Record names of all kinds of procedure
4173 objects. (Earlier, only closures were recorded.)
4175 * procprop.h: Added declaration of scm_i_name.
4177 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4178 (scm_make_gsubr): Record names of compiled closures.
4180 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4182 * debug.c, debug.h: Removed obsolete code.
4184 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4185 stacks.c: Renamed regs --> scm_contregs.
4187 * print.c (scm_free_print_state): Cleanup print state before
4188 returning it to pool. It is better to do it here than in
4189 scm_prin1 since scm_prin1 is called often.
4191 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4192 s_set_source_property_x): Check that first argument is a pair or a
4195 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4196 scm_i_line, scm_i_column and scm_i_breakpoint global.
4198 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4199 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4202 * debug.h: Added debug object smob declaration and macro
4205 * configure.in: Build with backtrace.o and stacks.o if debug
4208 * Makefile.in: Added entries for new files: backtrace.c,
4209 backtrace.h, stacks.c and stacks.h.
4211 * symbols.c (scm_sym2ovcell): Fixed documentation.
4213 * _scm.h (min, max): Added.
4215 * async.c: Moved `min' macro to _scm.h.
4217 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4218 SCM_BACKTRACE_INDENT.
4220 * eval.c: Added new debug options `maxdepth' and `indent'.
4222 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4224 * print.h: Added selector SCM_PRINT_STATE.
4226 * print.c: New functions: scm_make_print_state,
4227 scm_free_print_state.
4229 * print.h: Added declarations for scm_make_print_state,
4230 scm_free_print_state.
4232 * debug.c (scm_m_start_stack): New acro.
4234 * debug.h: Small cleanup.
4236 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4239 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

4264 More prototype-related changes from Marius Vollmer:
4265 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4266 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4267 * ports.h (ptobfuns): Added prototypes. This means some casting in
4269 * fports.c: Added casts for initializations, since the functions
4270 are defined to take FILE * as their stream argument, not SCM.
4271 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4272 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4273 to `char *str_data' to conform to prototype.
4275 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4277 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4279 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4281 * stime.c, stime.h: use SCM_P method.
4283 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4285 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4286 be given at least two arguments. Insist that lst's last element
4287 be a list, but don't make any requirements of its predecessors.
4289 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4291 * eval.c (scm_nconc2last): Revert last change; there seems to be
4292 other stuff going on here.
4294 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4296 * eval.c (scm_nconc2last): Make sure that each element of lst
4297 (which is a list of argument lists, except for the tail) is a
4298 proper list, i.e., finite and terminated by '().
4300 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4302 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4305 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4306 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4309 * vectors.c (scm_make_vector): Fill vectors with the undefined
4310 value, to help make Guile Scheme code more portable to other
4313 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4314 * symbols.h, tags.h: Doc fixes.
4316 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>

4320 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4322 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4323 want to subtract it from the modulus; we just want to leave it
4326 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4328 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to

4333 * throw.c (scm_catch_apply): Finished implementation of
4336 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4338 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4340 (scm_init_filesys): set "i/o-extensions" feature.
4343 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4345 * Makefile.in (root.o): Correct dependencies.
4347 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4349 * Makefile.in: Added dependency entry for root.o.
4351 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4352 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4354 * init.c (scm_start_stack): Set initial root continuation number
4357 * procs.c: New function: scm_thunk_p.
4359 * procs.h: Added declarations of scm_thunk_p.
4361 * root.c: Renamed `call-with-new-root' -->
4362 `call-with-dynamic-root'.
4363 (cwdr): Removed allocation of new root state. This should be done
4364 separately by use of scm_make_root.
4365 (scm_apply_with_dynamic_root): New function: Does what it
4366 sounds like. Needed when spawning threads.
4368 * root.h: Added member last_debug_frame to root state.
4369 Added #include "libguile/debug.h"
4371 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4372 arguments. The motivation is that code in root.c needs catch
4373 functionality, and we want to avoid code duplication.
4374 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4375 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4376 handlers that run without popping the stack into the dynwind
4379 * throw.h: Added prototypes for scm_catch_apply and
4382 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4384 * root.h (scm_root, scm_set_root): Decouple thread support details
4385 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4386 SCM_SET_THREAD_LOCAL_DATA.
4388 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4389 and tortoise scanning loop.
4391 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4393 * Makefile.in: Rebuild dependencies.
4395 * libguile.h: #include "libguile/print.h" before "smob.h", since
4396 the latter uses the print_state structure.
4398 * throw.c (scm_ithrow): Use the correct variable when checking to
4399 see if a given element of scm_dynwinds is a valid catch.
4401 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4402 structure, abort; don't just silently ignore the garbage.
4404 * _scm.h: #include "print.h" here, since it seems to be used just
4406 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4407 strports.c, unif.h: Don't #include "print.h".
4409 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4411 * feature.h (scm_loc_features): Removed external declaration.
4412 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4414 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4416 * feature.c (scm_init_feature): Added threads feature (needs to be
4417 initialized here, since features doesn't exist when
4418 scm_init_threads is called).
4420 * libguile.h: Added #include "libguile/../threads/threads.h".
4421 (This is a kludge to get thread support working. This should be
4424 * configure.in, acconfig.h: Added flags for thread support.
4426 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4429 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4430 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4433 * _scm.h: Added conditional #include "threads.h"
4435 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4436 SCM_THREADS_SWITCHING_CODE.
4438 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4439 allocate the basic dynamic root object.
4440 (scm_boot_guile): Added call to scm_init_root.
4442 * root.c, root.h: Added root smob.
4443 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4444 functions: Implements dynamic roots mostly according to spec in
4445 SCM manual. Main difference is that the second argument is a
4446 throw handler rather than an error "thunk".
4448 * root.h: Added declaration of scm_init_root.
4450 * root.c: Added #include "genio.h", #include "smob.h", #include
4451 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4453 (scm_init_root): Added #include "root.x".
4455 * throw.c: Added #include "stackchk.h"
4456 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4457 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4458 can be used in scm_call_with_new_root; Added reenabling of stack
4459 checking when catching a throw.
4461 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4463 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4465 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4466 element is not found, as per R4RS.
4468 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4470 * list.c: Doc fixes throughout.
4472 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4474 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4475 declare the char * to be const. Avoids a warning in rgx.c.
4477 * ports.h: spelling fix.
4479 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4482 * load.c (scm_sys_try_load_path): throw an error if file not found
4483 (like it says it in NEWS).
4485 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4487 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4488 PROPS slot to '(), not #f; it's an empty alist.
4490 * throw.h, throw.c: Use SCM_P instead of #if hair.
4492 Remove special support for uncaught throws; see throw.c for
4494 * throw.c (uncaught_throw): New function.
4495 (scm_ithrow): Call uncaught_throw if we don't find a throw
4496 target; don't mess with scm_bad_throw_vcell.
4497 (scm_bad_throw_vcell): Variable deleted.
4498 (scm_init_throw): Don't initialize it.
4500 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4503 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4505 * numbers.c (scm_istr2int): If the number is short (as most
4506 numbers are), just call scm_small_istr2int to deal with it.
4507 (scm_small_istr2int): New function, created by un-#ifdefing the
4508 non-bignum version of scm_istr2int and renaming it.
4510 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4512 * load.c (scm_sys_try_load): don't check whether value returned
4513 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4514 Change the Scheme name from %try-load to primitive-load.
4516 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4517 Can avoid passing a message, allowing it to be derived in the
4518 error handler (e.g., if we want to throw to the key both from
4521 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4523 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4524 references now have a new appearance which is more compact and
4525 also gives a clue about what the target of the reference is.
4526 By setting parameters in the print state, more fancy printing can
4527 be achieved. This is used by the (not yet commited) backtrace
4530 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4532 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4535 * print.c: Added #include "struct.h". Removed function
4538 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4539 scm_iprin1. Removed prototype for scm_prlist.
4541 * arbiters.c (prinarb),
4542 async.c (print_async),
4543 debug.c (prindebugobj, prinmemoized),
4544 eval.c (prinprom, prinmacro),
4545 filesys.c (scm_fd_print, scm_dir_print),
4547 mallocs.c (prinmalloc),
4548 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4549 smob.h (scm_smobfuns),
4550 srcprop.c (prinsrcprops),
4552 unif.c, unif.h (scm_raprin1, rapr1),
4553 variable.c (prin_var): Changed argument `int writing' to
4554 `scm_print_state *pstate'.
4556 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4557 that it will be called before scm_init_print.
4559 * print.c (scm_prin1): Print states are now allocated when calling
4560 scm_prin1 and then passed around to all printing functions as an
4561 argument. A cache `print_state_pool' enables reuse of print
4563 (scm_make_print_state): New function.
4564 (scm_iprin1): Adaption to print states.
4565 (scm_iprlist): An initial "hare and tortoise" scan brings down
4566 time complexity to O (depth * N). (Better time complexity will be
4567 achieved when the printing code is completely rewritten.)
4569 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4571 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4572 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4573 it gets done whether or not the cache variable has a value.
4575 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4577 Distinguish #f and ().
4578 * __scm.h: #undef SICP.
4579 * pairs.h (SCM_EOL): Delete this definition, equating it with
4581 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4582 the value it used to have. Doc fixes, too.
4584 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4586 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4587 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4588 Lord's implementation of structs, allowing for tail arrays as
4589 described in the manual. Also fixed some bugs. (Both the interface
4590 and the implementation should be improved.)
4592 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4594 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4595 People who whish to see the source can do `(print-enable 'source)'.
4596 Removed #ifdef DEBUG_EXTENSIONS.
4598 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4600 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4601 integer (assuming for now accepting an integer is a good thing).
4603 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4604 %S will be used instead for write'ing arguments.
4606 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4607 asserts. fix a few other asserts.
4608 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4609 scm_uniform_vector_ref, scm_array_set_x,
4610 scm_dimensions_to_unform_array): change args in
4611 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4612 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4613 scm_substring_fill_x): likewise.
4614 gsubr.c (scm_gsubr_apply): likewise.
4615 eval.c (SCM_APPLY): likewise.
4617 * eval.c (4 places): replace scm_everr with lgh_error or
4620 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4621 scm_memory_error): new procedures.
4622 scm_everr: deleted. can use scm_wta, dropping first two args.
4623 scm_error: convert NULL subr to SCM_BOOL_F.
4625 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4628 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4631 * error.c, error.h: new error keys: scm_arg_type_key,
4632 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4634 scm_wta: reimplement using lgh_error instead of scm_everr.
4636 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4638 * gdbint.c: scm_lread now has one more argument.
4640 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4641 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4642 loading source from non-file ports, which, e. g., happens when
4643 using the Emacs interface).
4645 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4648 * read.c: Added code for recording of positions of source code
4649 expressions; New functions: recsexpr, scm_lreadrecparen;
4650 _scm_make_srcprops --> scm_make_srcprops
4651 (scm_flush_ws): Removed updating of positions counters. This work
4652 is already done by scm_gen_getc
4654 * read.h: Added prototype for scm_lreadrecparen
4656 * print.c: Added #include "alist.h"
4658 * eval.c: Added #include "hash.h"
4660 * eq.c: Added #include "ramap.h"
4662 * options.c: Documentation fixes.
4664 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4665 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4666 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4667 --> scm_make_srcprops
4669 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4670 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4671 function calls in the definition of the whash access macros.
4673 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4675 * init.c (scm_boot_guile): Add level of indirection to
4676 scm_boot_guile_1() to ensure that stack base pointer is properly
4677 initialized. There was no guarantee that variable i was the
4678 highest/lowest variable on stack (i.e. the call frame of
4679 scm_boot_guile was not completely protected from gc).
4681 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4683 * ports.h (scm_port_table): put back file_name, it will be used to
4684 support debugging. Undo related changes in fports.c, ioext.c,
4687 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4689 * ports.h (scm_port_table): remove file_name member for now, it seems
4691 * fports.c (scm_open_file): don't set file_name in PTAB.
4692 (prinfport): don't use file_name in PTAB.
4693 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4694 * ports.c (scm_add_to_port_table): don't intialize file_name.
4695 (scm_port_file_name): remove for now.
4696 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4698 * fports.h (scm_mkfile): prototype deleted.
4699 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4701 * debug.c, unif.c: use scm_out_of_range instead of
4702 wta for range errors (ASSERT still needs work).
4704 * error.c, error.h (scm_out_of_range): new procedure.
4706 * error.c, error.h (scm_out_of_range_key): new key.
4708 * posix.c (scm_sync): #else was missing.
4710 * error.c, error.h: append _key to names scm_num_overflow and
4713 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4714 of consing an empty list.
4715 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4716 of macros, saves code and string space.
4717 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4718 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4719 lower case. Rename scm_syserror_m to scm_syserror_msg.
4720 error.h: prototypes for new procedures.
4722 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4724 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4726 * error.c, error.h: setup scm_num_overflow key.
4728 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4729 Remove definition of SCM_OVSCM_FLOW.
4731 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4733 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4734 explicit message and args.
4736 * error.c, error.h, __scm.h: change system_error_sym to
4739 * error.c (system_error_sym): remove leading %% from the Scheme name
4742 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4744 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4746 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4747 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4748 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4749 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4750 renamed. (These were introduced by unsupervised name
4753 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4755 * print.c: Added code for detection of circular references during
4756 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4757 a hook for printing of closures (accessible via print options).
4758 This leads to a split of calls to scm_iprin1 into two classes:
4759 elementary print operations (e. g. the code which prints a smob)
4760 still use scm_iprin1 while top level calls (like scm_display) use
4761 scm_prin1. scm_prin1 begins by clearing the data structure used
4762 to record reference information.
4764 * print.h: Added declarations of scm_prin1 and scm_prlist.
4766 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
4768 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
4770 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
4772 * error.c (err_head): scm_iprin1 --> scm_prin1
4774 * debug.c: Adjusted header comment.
4778 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4780 * strerror.c: Doc fix.
4782 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4784 * gdbint.c (gdb_read): Now possible to run during GC.
4785 (unmark_port, remark_port): New functions.
4787 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
4789 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
4790 of allocating a new string object. Also, increase size by
4791 the factor 2 instead of 1.5.
4793 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
4795 * __scm.h (SCM_P): Corrected to run under traditional C.
4797 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
4800 * async.c: Calls to scm_sysintern corrected.
4802 * async.h (scm_async_clock): Redundant declaration removed.
4804 * continuations.c (scm_dynthrow): Redundant declaration removed.
4806 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
4807 Definition typos corrected.
4809 * debug.h: Missing declarations of functions in debug.c added
4812 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
4813 Missing declarations to functions in eval.c added.
4815 * filesys.c: Possibly uninitialized variable rv.
4817 * gc.h (scm_object_addr, scm_unhash_name): Missing
4818 declarations of functions defined in gc.c added.
4820 * genio.c: Possible typos str_data -> wstr_data. ???
4822 * genio.c: Possibly unintended shadowing of local variable
4823 `int c' (gotos out of scope of inner `c'). ???
4825 * init.c: Uninitialized `SCM last' may be used.
4827 * ioext.h: (scm_sys_isatty_p): Typo.
4829 * list.h (scm_list_head): Missing prototype for function in
4832 * numbers.c (scm_two_doubles): Changed from extern to static
4833 (is used only within numbers.c).
4835 * numbers.h: Repeated declarations removed.
4837 * ports.h (scm_close_all_ports_except): Declaration for the
4838 function defined in ports.c added.
4840 * posix.h: Missing declarations added.
4842 * procs.h (scm_make_subr_opt): Missing declaration added.
4844 * socket.h (scm_sys_gethost): Missing declaration added.
4846 * socket.h: Redundant declarations removed (they are in fdsocket.h).
4848 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
4849 Missing declarations added.
4851 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
4853 * struct.c: Uninitialized variable `SCM answer' may be used.
4855 * unif.c (l2ra): Declaration prototype.
4857 * unif.c (scm_array_equal_p): Dummy definition removed (it is
4858 defined in ramap.c).
4860 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
4861 Redundant declarations removed (they are in ramap.h).
4863 * variable.h (scm_make_udvariable,
4864 scm_make_undefined_variable): Declaration corrected to
4865 correspond variable.c.
4867 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
4868 Missing declarations added.
4870 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
4872 * Makefile.in (distclean): Don't forget to delete fd.h.
4874 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4876 * fd.h.in, tags.h: Trivial cleanups.
4878 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
4879 marksweep.h just declared functions from gc.c.
4880 * gc.h, libguile.h: Don't #include "marksweep.h".
4881 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4882 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
4883 dependencies updated.
4885 * libguile.h: Don't #include "files.h"; it's been deleted.
4887 * files.c (scm_sys_delete_file): Moved to filesys.c.
4888 File is now empty; deleted.
4890 * filesys.c: scm_sys_delete_file is now here. Remove
4891 #if's; they seem to rely on remnants of an old portability
4892 regimen. If the problems come up again, solve them properly,
4893 using autoconf. Specifically: Don't test M_SYSV, and #define
4894 remove to be unlink if it's #defined; don't use remove just
4895 because HAVE_STDC_HEADERS is #defined.
4896 * filesys.h: Add declarations for scm_sys_delete_file.
4897 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4898 files.o, files.h, files.c, and files.x.
4899 * init.c: Don't #include "files.h", and don't call scm_init_files.
4901 Use SCM_P instead of PROTO; the latter intrudes on the user's
4903 * params.h: Deleted; definition of SCM_P moved to...
4904 * __scm.h: ... here, where it replaces PROTO macro.
4905 * libguile.h, smob.h: Don't #include "params.h".
4906 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
4907 smob.h: Fix prototypes accordingly.
4908 * Makefile.in: Update dependencies.
4909 (inner_h_files): Remove params.h.
4911 * gc.c: #include "gc.h"; every module should include its header,
4912 to let the compiler cross-check the declarations against the
4915 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
4916 simpos.h: #include "libguile/__scm.h".
4918 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
4920 * init.c: Don't forget to #include smob.h and init.h.
4921 * Makefile.in: Dependencies updated.
4923 * smob.h: Use PROTO instead of #if __STDC__.
4925 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
4927 * __scm.h: Doc fixes.
4929 * __scm.h, libguile.h: Use "quotes" in the #includes, not
4930 <angles>; this allows `make depends' to work properly.
4932 * libguile.h: #include smob.h and pairs.h before the others; they
4933 define typedefs used by other headers.
4935 C files should #include only the header files they need, not
4936 libguile.h (which #includes all the header files); the pointless
4937 recompilation was wasting my time.
4938 * Makefile.in (all .o dependency lists): Regenerated.
4939 * libguile.h: Don't try to get a definition for size_t here...
4940 * __scm.h: Do it here.
4941 * _scm.h: Since this is the internal libguile header, put things
4942 here that all (or a majority) of the libguile files will want.
4943 Don't #include <libguile.h> here; that generates dependencies on
4944 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
4945 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
4946 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

4982 "unif.h", "throw.h", "tag.h", "symbols.h", "struct.h",

5037 * unif.c: Get "unif.h", "feature.h", "strop.h", "sequences.h",

5042 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
5043 * weaks.c: Get "weaks.h".
5045 * stackchk.h: #include "libguile/debug.h",
5047 * print.h, read.h: #include "options.h", since everyone who uses
5048 either of these files will need that.
5050 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5051 anyone who uses this file will need them to define the smob
5052 printing functions. Also, get markers.h, since people will need
5053 to #define the mark functions.
5055 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5056 * ports.h: ... to here.
5058 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5059 don't rely on archaic C default type rules.
5061 * fports.h: #include "libguile/ports.h", since you need that in
5062 order to parse this.
5064 * genio.h: #include "libguile/print.h", because you need that to
5065 parse this; don't bother #including "ports.h", since print.h gets
5068 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5070 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5071 this; it's now a reference to an element of *scm_root.
5073 * debug.h: Don't #include "options.h"; the compiler won't be able
5074 to find that once the headers are installed; instead, #include
5075 "libguile/options.h".
5076 * gc.h: Same, with marksweep.h.
5077 * mbstrings.h: Same, with symbols.h.
5078 * scmhob.h: Same, with _scm.h.
5079 * smob.h: Same, with params.h.
5081 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5082 C files; there's no need for this, and it forces recompilations
5085 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5087 * error.c (scm_error): declare scm_error_callback.
5089 * error.h: prototype for scm_error_callback.
5091 * __scm.h: define lgh_error.
5092 (SCM_SYSERROR): redefine using lgh_error.
5094 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5096 * error.c (scm_error): new procedure.
5098 * error.h: prototype for scm_error.
5100 * Makefile.in (install): install scmconfig.h from the current
5101 directory, not $(srcdir).
5103 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5105 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5106 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5107 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
5108 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
5109 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
5110 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5111 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5112 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5113 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5114 vports.h, weaks.h: #include "libguile/__scm.h", not
5115 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5116 dependencies are within libguile properly.
5118 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5120 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5121 when scmconfig.h doesn't exist.
5123 * load.c (scm_sys_try_load): Correct spelling.
5125 * feature.c (scm_loc_features): Make this static.
5127 * Makefile.in (libpath.h): Omit trailing slash from path. We
5128 shouldn't require it of users, so why put it here?
5130 Move code to initialize and search %load-path from ice-9 to C
5131 code, so we can use the load-path to find the ice-9 boot code;
5132 this makes it easier to run Guile without installing it. See
5133 corresponding changes in guile/Makefile.in.
5134 * feature.c: Move stuff concerned with the load path to load.c.
5135 (scm_compiled_library_path): Deleted.
5136 Don't #include libpath.h here.
5137 * feature.h: Don't mention scm_compiled_library_path.
5138 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5139 <sys/stat.h>, and <unistd.h> (if present).
5140 (R_OK): #define if the system hasn't deigned to.
5141 (scm_loc_load_path): New variable.
5142 (scm_init_load_path, scm_sys_search_load_path,
5143 scm_sys_try_load_path): New functions.
5144 (scm_init_load): Initialize scm_loc_load_path to point to the
5145 value cell of the Scheme %load-path variable.
5146 * load.h: Add declarations for scm_sys_search_load_path,
5147 scm_sys_try_load_path.
5148 * init.c: Call scm_init_load_path.
5149 * Makefile.in (feature.o, load.o): Dependencies updated.
5151 * load.c, load.h: Rewrite using PROTO macro.
5153 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5155 * gc.c (scm_cellp): New function: C predicate to determine if an
5156 SCM value can be regarded as a pointer to a cell on the heap.
5158 * gc.h: Added declaration of scm_cellp.
5160 * gdb_interface.h: New file: The GDB interface header from the GDB
5163 * gdbint.c: New file: GDB interface.
5165 * gdbint.h: New file: GDB interface.
5167 * libguile.h: Added #include <libguile/gdbint.h>.
5169 * init.c (scm_boot_guile): Added scm_init_gdbint.
5171 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5172 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5173 found if object files and source are kept separate).
5175 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5177 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5179 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5181 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5182 TK_SRC_DIR; they're not relevant any more.
5184 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5185 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5187 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5189 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5190 search path, so we can find the <libguile/MUMBLE.h> headers.
5192 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5194 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5195 implicit in the .c.o rule.
5196 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5199 Put the library path in a header file, instead of passing it on
5200 the command line in every compilation.
5201 * Makefile.in (libpath.h): New target.
5202 (feature.o): Depend on libpath.h.
5203 (clean): Delete libpath.h.
5204 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5205 * feature.c: ... #include "libpath.h" here.
5206 * .cvsignore: Ignore libpath.h.
5208 Don't install the unwashed masses of Guile header files in the
5209 main #include path; put most of them in a subdirectory called
5210 'libguile'. This avoids naming conflicts between Guile header
5211 files and system header files (of which there were a few).
5212 * Makefile.in (pkgincludedir): Deleted.
5213 (innerincludedir): New variable; this and $(includedir) are enough.
5214 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5215 (installed_h_files): Divide this up. Now this variable lists
5216 those header files which should go into $(includedir) (i.e. appear
5217 directly in the #include path), and ...
5218 (inner_h_files): ... this new variable says which files appear in
5219 a subdirectory, and are referred to as <libguile/mumble.h>.
5220 (h_files): List them both.
5221 (install): Create innerincludedir, not pkgincludedir. Put
5222 the installed_h_files and inner_h_files in their proper places.
5223 (uninstall): Corresponding changes.
5224 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5225 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5226 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5227 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5228 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5229 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5230 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5231 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5232 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5233 vports.h, weaks.h: Find __scm.h in its new location.
5234 * __scm.h: Find scmconfig.h and tags.h in their new locations
5235 (they're both "inner" files).
5237 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5239 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5241 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5243 * posix.c: Doc fixes.
5245 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5247 * socket.c: Don't include a prototype for inet_aton; just use a
5248 K&R style declaration, to avoid warnings but minimize the chance
5249 of conflicts with the system.
5251 On NextStep, <utime.h> doesn't define struct utime, unless we
5252 #define _POSIX_SOURCE before #including it.
5253 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5254 * acconfig.h: New comment text for above CPP symbol.
5255 * configure.in: Call it.
5256 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5258 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5260 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5261 testing for __EMX__.
5263 * posix.c: #include <libc.h>, if it exists.
5265 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5266 don't even know if the latter exists.
5268 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5269 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5270 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5272 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5274 (scm_init_posix): Use them when initializing the Scheme constants
5277 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5279 * Makefile.in (libdir, includedir, bindir): Use the
5280 autoconf-supplied values, instead of deriving them ourselves.
5281 (pkgincludedir, datadir, pkgdatadir): New variables.
5282 (install, uninstall): Put the header files in a special
5283 subdirectory, not in the main search path.
5285 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5286 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5288 * Makefile.in (IMPLPATH): Deleted; never used.
5290 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5291 on the Tcl/Tk source any more.
5292 (INCLUDE_CFLAGS): Remove references to the above.
5294 * Makefile.in (version.o): Corrected dependencies.
5296 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5298 * libguile.h: #include "version.h"
5300 * init.c (scm_boot_guile): Call scm_init_version.
5301 * gscm.c (gscm_run_scm): Call scm_init_version.
5303 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5304 GUILE_VERSION): AC_DEFINE these.
5305 (acconfig.h): #undef the above symbols.
5307 * Makefile.in (libobjs): Add version.o.
5308 (installed_h_files): Add version.h.
5309 (c_files): Add version.c.
5310 (gen_c_files): Add version.x.
5311 (version.o): New rule.
5312 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5313 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5314 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
5315 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
5316 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5317 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5318 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5319 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5320 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5321 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5322 weaks.o): Add version.h to dependency lists.
5323 (markers.o): Remove duplicate rule.
5325 * version.h: New file.
5327 * version.c: New file.
5329 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5331 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5332 array; use it appropriately. Since GCC is quite happy to
5333 subscript functions, it never warned us about this; we should use
5334 -Wpointer-arith in the future. I guess we never tested
5337 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5339 * socket.c: Doc and copyright fixes.
5341 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5343 * debug.c: Fixed and improved gdb support.
5345 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5347 * socket.c: Added declaration of inet_aton to avoid compiler
5348 warning. (Hope this solution is correct.)
5350 * stime.c: Added declaration of ftime. (This is missing in
5353 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5355 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5357 * Makefile.in (c_files): add strerror.c.
5359 * strerror.c: new file from Emacs' sysdep.c.
5360 maybe configure should also check for sys_errlist.
5362 * configure.in (AC_REPLACE_FUNCS): add strerror.
5364 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5366 * debug.c (scm_init_debug): Added initialization for
5367 scm_evaluator_traps.
5369 * debug.h, debug.c: Various name changes.
5370 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5371 "debug-options-interface". See commentary in options.c.
5373 * options.h, options.c: Options now have documentation strings.
5374 Also added a long explanatory commentary.
5376 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5379 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5380 last_debug_info_frame is now updated in all cases.
5382 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5385 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5387 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5388 Added option STACK_CHECKING.
5390 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5392 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5394 * __scm.h: Removed symbols for debugging support.
5396 * acconfig.h: Added symbols for debugging support.
5398 * configure.in: Added user option for debugging support.
5399 --enable-debug will include the debugging code into libguile.a.
5401 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5402 scm_relocate_chunk_to_heap.
5404 * debug.c: New file: low-level debugging support. It also
5405 includes support for debugging with gdb. (The extensions to gdb
5406 are written by Per Bothner at Cygnus.)
5408 * debug.h: New file: low-level debugging support.
5410 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5411 argument pairs. Extensive modifications to the debugging
5412 evaluator. Added "SECTION:" commentaries to clarify what happens
5413 when, during double compilation. Renamed EVALIMP --> EVALIM.
5414 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5415 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5416 the beginning of the file. New procedure: scm_unmemocopy.
5417 Added some global state variables needed by the debugging
5418 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5419 check_entry, check_apply, check_exit, debug_options and
5420 evaluator_traps. New acro: undefine.
5422 * eval.h: Renamed EVAL --> XEVAL.
5424 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5425 --> scm_make_weak_key_hash_table.
5427 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5428 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5430 * libguile.h: Conditionally include debug.h
5432 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5433 scm_object_properties shouldn't return handle. `handle' now gets
5434 initialized in scm_set_object_properties_x. scm_object_properties
5435 doesn't any longer create an entry in scm_object_whash.
5437 * options.c: New file: handling of run time options.
5439 * options.h: New file: handling of run time options.
5441 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5443 * print.c: New procedure: scm_print_options
5445 * print.h: Defines for print options.
5447 * read.c: New procedure: scm_read_options
5449 * read.h: Defines for reader options.
5451 * root.h: Added scm_source_whash among scm_sys_protects.
5453 * srcprop.c: New file: source properties.
5455 * srcprop.h: New file: source properties.
5457 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5458 (Bug found by A. Green.)
5460 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5462 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5464 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5466 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5468 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5469 and should be called by the final client.
5471 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5473 * gc.h: Use the PROTO macro when declaring functions.
5474 * gc.c: Use the PROTO macro when declaring static functions.
5475 Remove the CPP hair around function definitions.
5477 * gc.c (scm_init_storage): Initialize scm_asyncs.
5479 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5480 preprocessor symbol; "__scm.h" is where it might get #defined.
5481 * __scm.h: Similar: #include <scmconfig.h> before testing
5484 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5486 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5488 * init.c (scm_boot_guile): Add init_func argument; call
5489 (*init_func) instead of calling scm_appinit; it's ucky to
5490 hard-code names for the user's procedures.
5491 * init.h (scm_boot_guile): Adjust declaration.
5493 * __scm.h (PROTO): New macro, for declaring functions with
5496 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5497 eliminate all the __STDC__ conditionals.
5498 (scm_boot_guile): Add declaration.
5499 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5500 Remove __STDC__ conditionals around function definitions; the
5501 declarations in init.h will provide the same information, more
5504 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5505 complain about it in the error message; the error message is
5506 adequate without that note, and there's nothing the user can do
5509 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5511 * Makefile.in (ancillary): Drop def.sed.
5513 * posix.c (scm_init_posix): Use numeric values, rather than
5514 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5515 F_OK. The symbols aren't available on some systems, and I'm
5516 pretty sure their values are fixed by common widespread practice.
5517 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5519 More functions unavailable on some systems.
5520 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5521 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5523 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5524 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5525 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5526 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5527 stub that signals an error as the #else.
5529 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5531 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5533 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5535 * unif.c: include ramap.h.
5537 * read.c (endif): case_insensative_p renamed case_insensitive_p.
5539 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
5541 * ports.c: include sys/ioctl.h.
5543 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5545 * configure.in: check for sys/ioctl.h.
5547 * ports.c: include <malloc.h> not "malloc.h".
5549 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5551 * fports.c: remove ttyname and tmpnam declarations.
5553 * posix.c: fewer ttyname declarations.
5555 * fports.c: include <string.h> not "string.h".
5557 * init.c, ioext.c: include string.h and unistd.h.
5559 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5561 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5562 genio.c, simpos.c, vports.c: include string.h.
5564 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5566 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5568 (scm_addr_buffer_size): change type from scm_sizet to int.
5569 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5570 from scm_sizet to int.
5572 * error.c: include unistd.h.
5574 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5577 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5579 * __scm.hd, def.sed: deleted.
5581 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5583 Changes for NeXT, suggested by Robert Brown.
5584 * configure.in: Call AC_TYPE_MODE_T.
5585 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5586 NeXT. Put header file list in alphabetical order.
5587 * configure, scmconfig.h.in: Regenerated.
5588 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5590 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5593 * acconfig.h: New file, providing documentation for the CPP
5594 symbols defined in configure.in
5595 * acconfig-1.5.h: Removed; superceded by the above.
5597 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5599 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5601 * fports.c (scm_open_file): don't return #f, throw error.
5603 * ioext.c (fileno): renamed from %fileno.
5604 (soft-fileno): deleted.
5606 * ports.c (scm_port_revealed): don't need to check for -1 from
5608 (scm_set_port_revealed_x): return unspecified, not #f.
5610 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5612 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5614 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5616 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
5618 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5620 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5621 This is necessary on Ultrix, and doesn't hurt portability.
5623 * Makefile.in (dist-dir): New target, implementing a new dist system.
5624 (installed_h_files): Put in alphabetical order.
5625 Remove duplicate entries for markers.h and unif.h.
5626 (c_files): Remove duplicate entries for markers.c.
5627 (ancillary): Renamed from anillery; all uses changed. Remove
5628 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5629 Remove all the ../doc/* files; doc/Makefile.in handles that.
5631 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5633 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5634 every if must have an else, or else the whole command has a
5635 non-zero exit code whenever the if's condition is false.
5637 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
5639 * posix.c: include string.h.
5641 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
5643 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
5646 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
5647 Remove leading % from scheme names.
5648 Do not return error values, call SCM_SYSERROR or similar.
5650 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
5652 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
5654 * struct.c (scm_init_struct): new file.
5656 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
5658 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
5659 (scm_list_head): added list-head for rapidly chopping argument
5660 lists off of longer lists (and similar).
5662 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
5664 * objprop.c (scm_object_property): assq the cdr of the whash
5665 handle for obj, not the handle itself.
5667 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
5669 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
5670 weak hash tables last of all marking to avoid an obscure gc bug.
5671 WARNING: circular lists stored in a weak hash table will hose us.
5673 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
5675 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
5676 new functions similar to scm_substring_move_left_x and
5677 scm_substring_move_right_x.
5679 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
5681 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
5684 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
5686 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
5688 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
5690 * strports.c (scm_strprint_obj): convenience function. C for
5691 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
5693 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
5694 removed to a separate library
5696 * init.c (scm_boot_guile): copied from guile-tcl.c.
5697 Initialization specific to tcl interpreters removed.
5699 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
5701 * ports.c (scm_ports_prehistory): size malloced here doesn't
5702 matter so long as it is non-0 (got rid of "* 4").
5704 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
5706 * gscm.h: gscm_mkarray eliminated (presumably was not being used
5707 since its definition was bogus).
5709 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
5711 * mallocs.[ch]: back again (for rx at least).
5713 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
5715 * ports.c: removed functions relating to the mapping between ports
5716 and descriptors. (That stuff is unix-specific and should be collected
5717 in a separate library).
5719 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
5720 (Tom Mckay@avanticorp.com)
5722 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
5724 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
5725 handled correctly (SCM_FREEP was applied to them) -- test for
5726 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
5727 being overwritten with #f. (brown@grettir.bibliotech.com)
5729 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
5731 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
5732 for a specific symbol or for all symbols.
5734 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
5736 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
5737 keys and weak values confused).
5739 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
5741 * list.c (scm_last_pair): map '()=>'()
5743 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
5745 * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
5746 Generalized assoc and hash-table functions.
5747 Factored pairs.c into multiple files.
5749 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
5751 * gscm.c (gscm_run_scm): got rid of objprop.
5753 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
5755 * genio.c (scm_getc):
5756 NOTE: fgetc may not be interruptable.
5758 * procprop.c (scm_stand_in_scm_proc):
5759 NOTE: don't use a alist here.
5760 (scm_set_procedure_properties_x): fix type checking throughout this file.
5762 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
5764 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
5765 after freeing part of the port table.
5767 Thu Feb 29 16:21:17 1996 Tom Lord <lord@beehive>
5769 * strports.c (scm_mkstrport):
5770 * vports.c (scm_make_soft_port): allocate a port table entry
5771 (possibly triggering gc) before setting the tag of the corresponding
5774 * pairs.c (scm_delq_x): never throw an error.
5776 * vectors.c (scm_make_vector): made the default vector fill argument
5777 into '() (much more useful than the previous value, "#unspecified")
5779 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
5781 * ports.c (scm_add_to_port_table): Added fields
5782 to port table entries: file_name, line_num, col.
5783 Update these in open_file, gen_getc and gen_ungetc.
5784 Added procedures to access those fields.

5894 initialization to fix a race condition.
5896 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
