1 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
3 Include the source location in error messages for scripts.
4 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
5 stack is still there when we catch the error.
6 * throw.c (handler_message): If we are handling an error with a
7 message, then put together the proper arguments and call
8 scm_display_error, instead of scm_display_error_message. That
9 displays source location, if it can find it.
11 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
13 * gc.c (scm_unprotect_object): Change this so that calls to
14 scm_protect_object and scm_unprotect_object nest properly.
15 (scm_protect_object): Doc fixes.
17 * strings.c (scm_string_set_x): Require the argument to be a
18 writable string, not a substring or a symbol.
19 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
20 (Thanks to John Redford and Charbel Jacquin.)
22 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
24 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
26 * eval.c (safe_setjmp): Remove this misunderstanding.
27 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
30 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
32 * libguile.h: Mark these as C declarations, for compilation by C++
35 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
36 __cplusplus clause. I seriously doubt this ever worked the way
37 the author seems to have intended.
39 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
41 Utterly needless cleanups to hopelessly messy code.
43 (scm_fflush): Moved to ...
44 * genio.c (scm_fflush): ... here, amongst all the other port
45 method invocation functions.
46 * genio.h, ports.h: The prototype moves too.
48 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
50 * backtrace.c (display_error_body): The current frame does not
51 always have a parent frame; consider a function called directly
52 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
55 * alloca.c (alloca): Undo yesterday's changes, and simply call
56 malloc directly for storage, and abort if we don't get what we
57 want. The situation is much simpler --- just call malloc. Emacs
58 has bizarre/evil requirements (signal handlers might malloc unless
59 you set this global flag, so you have to set the flag around all
60 calls to malloc) which we are certainly not going to conform to,
61 so we can do the simple and obvious thing.
63 * coop.c (coop_condition_variable_wait): Make this function
64 static. It's only useful internally --- you should never just
65 wait on a condition variable.
66 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
68 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
70 * unif.c (scm_array_set_x): Accept any kind of number as an
71 element for a uniform vector of doubles. This is more consistent
72 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
74 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
75 works; I can't conveniently test it myself. (Thanks to Dvid
76 Tillman for the bug report.)
80 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
81 from here, not from scm_compile_shell_switches (which is a pretty
83 (scm_load_startup_files): New function.
84 (scm_ice_9_already_loaded): Variable moved to here from script.c.
85 * script.c (scm_compile_shell_switches): Don't load the startup
87 (scm_ice_9_already_loaded): Variable moved.
88 * init.c (scm_load_startup_files): Prototype for new function.
89 * gh_init.c (gh_enter): Doc fix.
91 1998-10-03 <jimb@savonarola.red-bean.com>
93 Some anti-warning changes from Greg Harvey.
94 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
95 warnings when it doesn't understand our NORETURN declarations in
97 * posix.c (scm_mknod): Similar.
99 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
101 * posix.c (scm_getpwuid): If we can't find an entry, return our
102 own message, instead of using scm_syserror --- the getpwMUMBLE
103 functions don't set `errno' to anything interesting.
105 1998-10-03 <jimb@savonarola.red-bean.com>
107 Get rid of warnings from the cooperative threading system.
108 * threads.h (scm_single_thread_p, scm_yield,
109 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
110 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
111 scm_wait_condition_variable, scm_signal_condition_variable): Add
112 prototypes for these Scheme-visible functions.
113 * coop-defs.h (coop_next_runnable_thread,
114 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
115 Prototypes for these here, even though they're from iselect.c.
116 (coop_condition_variable_wait, coop_join): Add prototypes.
117 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
118 scm_threads_free_condvar): Make these smob functions static.
119 * coop-threads.h (coop_init): Give this a real prototype.
120 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
121 (coop_next_runnable_thread): No need to provide prototype; it's in
124 * scmconfig.h.in: .detarenegeR
126 * iselect.c, threads.c: Doc fixes.
128 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
130 * Makefile.in: Regenerated with a patched automake, to get
131 dependency generation right when using EGCS.
133 * inet_aton.c (inet_aton): Add prototype, to remove compiler
134 warning. (Thanks to Robert Pluim.)
136 * inet_aton.c (inet_aton): Reassure the compiler that the
137 arguments to the <ctype.h> macros are all unsigned characters, not
140 1998-10-03 <jimb@savonarola.red-bean.com>
142 Getting rid of more warnings...
143 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
144 today's change to ../configure.in.
145 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
146 * scmconfig.h.in: Regenertaded.de.,.__
147 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
148 (scm_localtime, scm_mktime): Use a const char * to manipulate the
151 * readline.c: Doc fix.
152 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
153 * readline.h (scm_filename_completion_function): Add prototype.
154 (scm_init_readline): Make this into a prototype.
156 * readline.c (scm_filename_completion_function): Use SCM_PROC to
157 declare this, instead of calling scm_make_subr manually.
159 1998-10-02 <jimb@savonarola.red-bean.com>
161 * readline.h (scm_init_readline): Add prototype for this.
162 (scm_init_readline): Make this a real prototype.
164 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
166 Warning fixes from Maciej Stachowiak:
167 * backtrace.h (scm_display_application, scm_backtrace): Add
169 * debug.c (scm_m_start_stack): Make this function static.
170 * fluids.h (scm_fluid_p): Add prototype.
171 * procprop.c (scm_i_procedure_arity): Make this function static.
172 * regex-posix.c (scm_regexp_error_msg): Make this function static.
173 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
174 * root.h (scm_dynamic_root): Add external prototype.
175 * scmsigs.h (scm_usleep): Add external prototype.
176 * script.h (scm_init_script): Use prototype, not K&R decl.
177 * stacks.h (scm_stack_id): Add external prototype.
178 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
180 1998-09-30 Mark Galassi <rosalia@cygnus.com>
182 * gh.h: took out the definitions of vset and vref, since they are
183 replaced by the proper vector routines that correspond to the R4RS
186 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
188 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
189 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
190 third argument, a C expression that should result in a SCM value,
191 which is used to initialize the variable. Reimplemented
192 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
195 * version.h (scm_libguile_config_stamp): Add prototype.
196 (From Maciej Stachowiak.)
198 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
200 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
201 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
203 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
205 * print.c (scm_iprin1): Rather than having one i, and using it in
206 several places, declare a fresh i local to each block where it is
207 used, and give it a signedness appropriate to its use in each case.
210 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
213 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
214 signed/unsigned clashes.
216 * posix.h (scm_tmpnam): Added prototype.
218 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
219 scm_make_subclass_object): Add external prototypes.
221 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
222 comparison is okay here.
224 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
226 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
227 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
229 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
232 * load.c (swap_port): Make this function static.
234 * load.c (scm_search_path): Make max_path_len and max_ext_len
235 unsigned, since they're compared against string sizes.
237 * load.c (init_build_info): Make i unsigned.
239 * ioext.h (scm_read_line): Add prototype.
241 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
242 scm_hash_fn_remove_x): Make hash bucket index local variable k
243 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
244 accurately as possible.
246 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
247 comparisons, and range checking to make sure those casts are
250 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
251 signed/unsigned comparisons.
253 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
254 avoid signed/unsigned comparisons.
255 * smob.h (scm_numsmob): Change extern declaration to match.
257 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
258 avoid signed/unsigned comparisons.
259 * ports.h (scm_numptob): Change extern declaration to match.
260 (scm_current_load_port, scm_set_port_line_x,
261 scm_set_port_column_x): New prototypes.
263 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
264 test code, and it causes warnings.
266 * gh.h (gh_int2scmb, gh_uniform_vector_length,
267 gh_uniform_vector_ref): Added prototypes.
269 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
270 debugging support unconditionally. That's backtrace.c, stack.c,
271 debug.c, and srcprop.c.
272 (EXTRA_libguile_la_SOURCES): Omit those from here.
273 * Makefile.in: Regenerated.
275 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
277 * options.c (scm_options): Bugfix: Allow empty list of options!
279 * debug.c, debug.h (scm_single_step): Removed.
280 (scm_with_traps): New procedure. This procedure could easily be
281 written in Scheme but needs to be highly optimized.
283 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
285 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
286 Check SCM_TRAPS_P before trapping.
288 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
290 Changes to avoid signed/unsigned comparison warnings.
291 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
292 (scm_gc_sweep): Make n and j local to the blocks they're used in,
293 so they can have appropriate types for each application. Make i
294 signed. Use initializers in some spots. I'll probably pay for
296 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
297 (scm_must_realloc): Make nm unsigned.
298 (init_heap_seg): Make new_seg_index and n_new_objects signed.
299 (scm_init_storage): Use prototype-style definition, and make the
301 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
302 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
304 * filesys.c (scm_readlink): Make local vars rv and size ints, to
305 avoid signed/unsigned comparison warnings, and because the return
306 value of readlink may be -1. Don't bother casting the third
307 argument to readlink.
309 * filesys.c (scm_dirname, scm_basename): Move these to their own
310 page, at the end of the file.
311 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
313 * eval.h (scm_eval_options_interface): Add external prototype for this.
314 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
316 * eval.c (scm_lookupcar1): Make this static.
318 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
319 Make these prototype declarations, not K&R-style.
321 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
322 unsigned comparison warning.
324 * appinit.c: File removed. It had a single function in it, empty,
325 whose reason for existence is explained in no documentation or
326 comment. I think it's there as a default for some Tcl-style
327 initialization, but Tcl abandoned that approach a while ago.
328 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
329 (BUILT_SOURCES): Remove appinit.x.
330 * Makefile.in: Regenerated.
332 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
334 * Makefile.in: Regenerated using the last public version of
335 automake, not the hacked Cygnus version.
337 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
339 Remove Totoro kludge.
340 * Makefile.in, scmconfig.h.in: Regenerated.
341 * init.c, readline.c: Don't check if TOTORO is #defined.
343 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
345 * Makefile.am: Adjust for new thread configuration system.
346 (INCLUDES): Include the value of THREAD_CPPFLAGS.
347 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
349 (THREAD_LIBS): Definition deleted; automake will generate such
350 things automatically.
351 * Makefile.in: Regenerated.
353 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
355 Simplify smob and port marking; set the mark bit in the generic
356 marking code, and make marker routines only responsible for
357 turning up outgoing pointers.
358 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
359 before calling the marking function. Don't call the marking
360 function if it's zero.
361 * markers.c (scm_mark0): Just return #f. This function isn't
362 necessary at all now, but it's harmless to call it. We'll leave
363 it in so other folks' code doesn't croak at link time.
364 (scm_markcdr): Don't call SCM_SETGC8MARK.
365 * async.c (mark_async): Don't call SCM_SETGC8MARK.
366 * dynl.c (mark_dynl_obj): Same.
367 * root.c (mark_root): Same.
368 * srcprop.c (marksrcprops): Same.
369 * unif.c (markra): Same.
370 * variable.c (scm_markvar): Same.
371 * ports.c (scm_markstream): Same.
372 (void_port_ptob): Specify zero for our marking function.
373 * debug.c (debugobjsmob): Same.
374 * dynwind.c (guardsmob): Same.
375 * filesys.c (dir_smob): Same.
376 * fluids.c (fluid_smob): Same.
377 * fports.c (scm_fptob, scm_pipob): Same.
378 * mallocs.c (mallocsmob): Same.
379 * regex-posix.c (regex_t_smob): Same.
380 * smob.c (freecell, flob, bigob): Same.
381 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
382 * throw.c (jbsmob, lazy_catch_funs): Same.
384 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
386 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
387 scm_copy_tree on code in order not to let memoized code to leak
388 out. Thus, scm_copy_tree needs to copy vectors as well since
389 quasiquote can introduce evaluated code also inside vector
392 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
394 * eval.c (scm_copy_tree): Removed ability to copy vectors.
396 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
397 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
400 * unif.c: Say that ivect and uvect are of type signed and unsigned
401 long instead of int in commentary so that it correctly describes
404 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
406 * stime.c: Removed declaration of strptime. (It should be
407 declared by the system headers. If it turns out that some systems
408 don't, we'll handle that then.) (Thanks to Greg Troxel.)
410 * stime.h: Renamed TIMEH --> STIMEH
412 * backtrace.c (scm_display_error, scm_display_backtrace): In order
413 to increase portability, don't use structure assignment.
414 (Thanks to Nicolas Neuss.)
416 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
418 (finalize_fd_sets): Added empty statement after last case label.
419 (Thanks to Nicolas Neuss.)
421 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
424 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
426 * init.c, readline.c: OK, I won't have these readline.x bug
427 reports anymore. We've had them since April. The current reason
428 is a completely unintelligible failure of totoro.red-bean.com to
429 do the test for rl_getc_function in libreadline correctly. This
430 kludge overrides the test if we're on totoro so that the snapshot
431 generation process can work.
433 * readline.c: Define a strdup replacement if not existent on system.
435 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
437 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
438 This change makes scm_make_vector R5RS compatible. We cannot keep
439 the third argument since people want to be able to deduce the form
440 of the C function call only by looking at R5RS. (At the same time
441 we have removed some unnecessary complexity!)
443 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
444 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
445 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
446 argument in call to scm_make_vector.
448 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
450 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
451 This macro is useful in applications.
453 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
455 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
456 (scm_parse_path, scm_search_path): New Scheme level procedures.
458 * load.h (scm_internal_parse_path, scm_parse_path,
459 scm_search_path): Declared.
461 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
463 * filesys.c (dirname, basename): New procedures.
465 * init.c (scm_boot_guile_1): Removed condition around
468 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
469 new data type (guards) for representation of C level guards and
470 data on the wind chain.
471 (scm_internal_dynamic_wind): New function.
473 * dynwind.h: Declare scm_internal_dynamic_wind.
475 * root.h (scm_root_state): Added scm_cur_loadp.
477 * root.c (mark_root): Added comment about cur_loadp.
479 * load.c: #include "dynwind.h";
480 (scm_primitive_load): Use scm_inner_dynamic_wind to update
483 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
485 * ports.c (current-load-port): New procedure.
487 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
489 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
490 not a tty, return #f.
492 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
493 to Julian Satchell and Roland Kaufmann.)
495 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
496 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
498 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
500 * debug.h, debug.c (scm_start_stack): New function. Implements
501 the guts of old scm_m_start_stack.
503 * debug.c (scm_m_start_stack): Use scm_start_stack.
505 * init.c (scm_start_stack, scm_restart_stack): Renamed to
506 start_stack and restart_stack. (These have static scope.)
508 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
510 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
511 readline functions to come in release 2.3. (Thanks to Chet
513 (handle_errors): Use the above functions.
515 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
517 * readline.c: Improvements for readline support: Handle errors
518 better; Implement before-read-hook.
520 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
522 * init.c (scm_boot_guile_1), readline.c: Test for
523 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
524 assure that we have version >= 2.1.)
526 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
528 * readline.c (scm_readline): Defer interrupts while we're calling
531 * readline.c (scm_add_history): Bugfix: Do strdup before giving
532 away the string to add_history.
533 (completion_function): Do completion for readline. (Thanks to
535 (scm_filename_completion_function): New procedure: Filename
537 (current_input_getc): New function. Use this one instead of
538 standard getc from readline.
540 * throw.c, throw.h (scm_handle_by_throw): New function: This
541 handler throws errors to next handler on the dynwind chain.
543 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
545 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
548 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
550 * procprop.c (scm_i_procedure_arity): New function. Returns arity
552 (scm_procedure_properties): Modified to return arity together with
554 (scm_procedure_property): Added the read-only property `arity'.
555 (scm_set_procedure_property_x): It is an error to set the `arity'
558 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
559 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
561 * procprop.h (scm_sym_arity): New symbol.
563 * objects.c (scm_set_object_procedure_x): New procedure: Use this
564 to set the dispatch procedure of an operator or entity object.
566 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
567 Made procedure slots read-only.
569 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
570 scm_tcs_cons_gloc case in zero args switch; Fixed args
571 construction for operators in scm_tcs_cons_gloc case in two args
574 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
576 * fluids.c: Removed use of assert.h (in order to avoid
579 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
581 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
583 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
584 change makes the evaluator safer at the cost of evaluation speed.
585 It handles the case when the user has added a non-immediate
586 improper end of the application form, e.g., `(+ 0 . x)'.
587 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
588 minimize the extra cost as much as possible. The new code is
589 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
590 problem with structs planted directly in the code (e.g. by a
591 macro). This no longer causes segmentation fault. (Thanks to
594 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
595 arg `proc' in order to be able to throw errors; New argument
598 * Removed extra #include "debug.h"
600 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
602 * scmsigs.c: Declare usleep as returning void on some systems.
603 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
606 * coop.c (usleep): Return void on some systems.
608 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
610 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
612 * coop.c: Changed return type of usleep to int.
614 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
615 isn't found in the OS.
617 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
618 isn't enabled. (Thought that I had made this change ages ago...)
620 * iselect.c: Declare bzero if not defined by OS.
622 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
624 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
625 condition. (Thanks to John Tobey.)
627 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
628 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
631 * __scm.h: Start the long-term project of moving to POSIX threads.
632 Phase 1: Classification of all critical sections.
633 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
634 for A sections. (See comments in __scm.h for details.)
636 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
637 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
639 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
641 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
642 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
643 (libpath.h, versiondat.h): Replaced dependency on Makefile with
644 dependencies on $(srcdir)/Makefile.in
645 $(top_builddir)/config.status in order to avoid circularity.
647 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
648 from argc if argc was 0 initially.
650 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
651 in generation of libpath.h.
653 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
655 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
656 libguile from 2 to 3.
658 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
660 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
662 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
664 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
665 scm_set_port_column_x, scm_port_filename,
666 scm_set_port_filename_x): Removed optional arguments. Added
667 proper argument checking.
669 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
670 stack size in machine words.
672 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
673 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
674 to Ole Myren Röhne.)
676 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
678 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
679 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
681 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
684 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
685 procedure apply: Copy argument lists before pushing them unto the
686 environment so that the environment won't get mutated due to
687 manipulation of procedure arguments. This should perhaps be
688 regarded as a temporary solution until someone finds a more
689 efficient one. (Thanks to Maciej Stachowiak.)
691 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
693 * script.c (scm_compile_shell_switches): Use "guile" as default
694 zero arg if argc is NULL.
696 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
698 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
699 is zero. (Thanks to Dirk Herrmann.)
701 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
703 * ports.c (scm_add_to_port_table): First line is now line 0
704 (was 1). (Interface changed according to suggestion by Per
707 * backtrace.c (display_header): Add 1 to line and column numbers
708 when presenting them to the user.
710 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
711 from debug.c --> eval.c
713 * eval.h, eval.c (scm_eval_options_interface): New options
715 (SCM_EVAL_STACK): New option: Size of newly created stacks,
716 i.e. stacks for new threads.
718 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
720 * eval.c (unsafe_setjmp): Removed with #if 0.
722 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
725 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
726 to avoid compiler warnings.
728 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
730 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
732 * throw.c (handler_message): Print message on current error port
733 instead of default error port. (Thanks to Maciej Stachowiak.)
735 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
737 * ports.c (scm_add_to_port_table): allocate in units of
738 struct scm_port_table *, not struct scm_port_table.
739 * posix.c (scm_close_pipe): remove the port from the port table
741 Thanks to Rob Engle for both fixes.
743 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
745 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
746 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
748 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
750 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
752 * backtrace.c (display_error_body, display_backtrace_body),
753 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
754 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
755 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
756 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
759 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
760 don't receive the jmpbuf arg anylonger.
761 (scm_catch): Don't accept a #f tag.
762 (scm_throw): Check that key is a symbol.
763 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
765 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
767 * async.c (async_pending): Removed declaration.
769 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
771 * dynwind.c (scm_wind_chain): New debug function.
773 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
774 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
775 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
776 extra layer of functions around the body and handler of a thread.
777 This extra layer makes sure that the handler is called in the
778 dynamic context of the surround (= empty dynwind list), but under
779 the *dynamic root* of the body. We can not use the dynamic root
780 of the surround since that root belongs to another thread => stack
781 is not handled correctly. It may seem ugly to use this extra
782 layer, but the extra cost in terms of execution time is really
783 negligible compared to the total amount of time required to create
784 a thread, and it would reduce maintainability to duplicate the
785 crucial and complicated steps performed by cwdr.
787 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
788 (SCM_ALLOW_INTS): Added thread switching code before interrupts
789 get re-enabled. The important effect of this is that interrupts
790 are blocked during thread switching so that thread data structures
791 don't risk getting messed up by an unfortunate signal.
792 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
793 seems to do more aggressive optimization which actually move
794 instructions around in these macros in a fatal way. Therefore:
795 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
796 just superstitious...)
797 (SCM_TICK): Maybe do a context switch and take care of asyncs.
798 This macro should be used instead of SCM_ASYNC_TICK since the
799 latter doesn't do context switches any more.
801 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
802 instead of SCM_ASYNC_TICK.
804 * coop.c, iselect.c: Since thread switches are now performed with
805 interrupts masked, we can't use the old mechanism of delivering
806 signals immediately when they arrive. Signals must instead be
807 delivered when the asyncs run *after* the end of the critical
808 section in scm_internal_select. But this also means after context
809 switch so that the signal will be delivered to a different thread.
810 To avoid this, I have changed the protocol of
811 coop_wait_for_runnable_thread and friends so that they are allowed
812 to return the original thread. So, if a signal arrives during
813 scm_internal_select, we won't any longer be forced do a context
814 switch, but can remain in the same thread and deliver the signal
817 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
818 scm_asyncs_pending and made it global.
820 * iselect.c: Small fixes.
822 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
823 coop_condition_variable_init, coop_condition_variable_wait,
824 coop_condition_variable_signal): Changed return type from `void'
825 to `int'. This is to adhere closer to the pthreads interface.
826 This, in turn, is part of an attempt to provide C versions of the
827 mutex and condition variable primitives which can be part of a
828 frontend to COOP or pthreads.
830 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
831 coop_condition_variable_destroy): New functions.
833 * coop-threads.c (scm_wait_condition_variable): Use
834 coop_condition_variable_wait_mutex.
836 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
837 Definitions moved to coop-defs.h.
839 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
840 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
841 scm_cond_destroy): New C interface to mutecis and cond vars.
843 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
845 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
847 * iselect.c: Now several threads can wait on the same file
848 descriptor. The behaviour is compatible with OS select: All
849 threads waiting for the fd return with the same status.
851 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
853 * coop-threads.c, threads.h (scm_spawn_thread): New function.
854 Can spawn a thread from application C code.
856 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
858 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
859 gh_doubles2scm): New functions.
861 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
863 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
864 commented-out version of gh_eval_str()
866 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
868 * socket.c (scm_bind): free soka after use.
870 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
872 * stime.c (tzvar): new variable.
873 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
874 avoid memory leaks when allocating.
876 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
878 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
881 * gc.c, tags.h: Doc fixes.
883 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
885 * eval.c (macro-eval!): Removed. This function was a design bug.
886 It allowed memoized code to leak out to the scheme level. Most
887 things that you could do with `macro-eval!' can be done with
890 1997-12-20 Tim Pierce <twp@skepsis.com>
892 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
893 scm_fgets now depends on ftell(3) to know how many bytes were
896 1997-12-15 Tim Pierce <twp@skepsis.com>
898 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
899 dealing with strings.
901 1997-12-13 Tim Pierce <twp@skepsis.com>
903 Make %read-line more suitable for implementing read-line efficiently.
904 * ioext.c (scm_read_line): Strip the terminating newline from a
905 string, and return a cons of the string and its terminator.
907 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
908 of the string that is read is stored in this memory location.
909 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
910 * genio.c, genio.h (scm_do_read_line): Update caller.
911 * ports.h (scm_ptobfuns): Update typedef.
912 * fports.c (scm_fptob, scm_pipob): Update struct.
914 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
916 * filesys.c (set_element): Return file descriptor.
917 (fill_select_type): Return the highest file descriptor.
918 (scm_select): Tell select about the highest file descriptor. On
919 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
920 Therefore the extra overhead for calculating the maximum fd seems
921 to be more than compensated. Is this correct? In any case,
922 scm_internal_select will be much faster with this info.
923 (scm_select, fill_select_type, set_element): Don't accept any kind
924 of object in the file descriptor list or vector.
926 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
928 * iselect.c (finalize_fd_sets): Bugfix.
930 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
932 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
933 when using scm_internal_select (since we might switch to another
936 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
938 * simpos.c (scm_system): always define: use sysmissing if not
939 available. Check for HAVE_SYSTEM instead of _Windows (does
940 Windows lack system or does it have an unusable one?).
941 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
942 Let the argument be optional: if not supplied, call system(NULL).
944 * ports.c (scm_close_port): relax the type check from OPPORTP to
945 PORTP; closing a closed port is allowed.
947 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
949 * fports.c (scm_fgets): Return if the last char in a chunk is
950 newline. When fgets returns a string whose length is `size-1', it
951 is ambiguous whether a whole line was retrieved, so we must check
952 explicitly whether a line terminator is present.
954 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
956 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
957 before taking the CDR. (Thanks to Harald Meland.)
959 * filesys.c (scm_stat): Slightly optimized.
961 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
963 * ports.c (scm_close_port): Make sure the port is open before
966 * guile-snarf.in: Pass args through to gcc in a way that preserves
967 whitespace boundaries. (Thanks to Greg Badros.)
969 1997-12-02 Tim Pierce <twp@skepsis.com>
971 * stacks.c (scm_frame_procedure): Reverse the logic in the return
972 statement. (Thanks to Doug Evans for pointing this out.)
974 1997-12-01 Tim Pierce <twp@skepsis.com>
976 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
978 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
980 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
981 errno macro expansion of this field name. (errno is a C
982 preprocessor macro on some systems.)
984 1997-11-29 Tim Pierce <twp@skepsis.com>
986 * iselect.c: Doc fix.
988 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
990 * init.c (scm_start_stack): Removed initialization of
991 scm_the_last_stack_var.
993 * backtrace.h: Declare scm_the_last_stack_var.
995 * backtrace.c: Define scm_the_last_stack_var.
997 * root.c (mark_root): Don't mark the_last_stack_var.
999 * root.h (scm_root_state): Removed the_last_stack_var.
1001 * throw.c: Added #include "fluids.h"
1002 (ss_handler): `the-last-stack' is now a fluid.
1004 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
1005 --> the_last_stack_fluid.
1007 * backtrace.c: Added #include "fluids.h"
1008 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
1009 (scm_backtrace): `the-last-stack' is now a fluid.
1011 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
1012 after scm_init_fluids.
1014 1997-11-28 Tim Pierce <twp@skepsis.com>
1016 * iselect.c: #ifdef USE_THREADS around thread-related includes.
1018 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
1019 DLSYM_ADDS_USCORE to decide whether to add an underscore.
1021 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1023 * iselect.c (coop_next_runnable_thread,
1024 coop_wait_for_runnable_thread): Disable interrupts so that no
1025 async is executed before a potential error_revive.
1026 (scm_internal_select): Disable interrupts during the parts of the
1027 code which manipulate the sleep queue and the file descriptors.
1029 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1031 * Makefile.am: Added iselect.c and iselect.h.
1033 * coop.c (coop_qinit): Initialize fields used by
1034 scm_internal_select.
1035 (coop_qget, coop_qget, coop_tmp_queue): Made global.
1036 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
1037 replacement in iselect.c.
1038 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
1039 coop_join): If GUILE_ISELECT enabled, use
1040 coop_wait_for_runnable_thread instead of
1041 coop_next_runnable_thread.
1042 (usleep, sleep): New replacements for system functions if
1043 GUILE_ISELECT is enabled.
1045 * coop-threads.h: Declare coop_wait_for_runnable_thread.
1047 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
1049 * filesys.c: Added #include "iselect.h". Moved FD-macros to
1050 iselect.h. Implement Scheme level `select' using
1051 scm_internal_select. (See NEWS.)
1053 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
1055 * init.c: Call scm_init_iselect.
1057 * iselect.h, iselect.c: New files. Implements
1058 scm_internal_select. (See NEWS.)
1060 1997-11-27 Tim Pierce <twp@skepsis.com>
1062 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
1063 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
1064 and scm_must_free, since ultimately the string returned will be copied
1065 by scm_makfrom0str anyway. Also, read any characters that may have
1066 been pushed onto the port with scm_ungetc.
1067 * ports.c (scm_generic_fgets): Same as for scm_fgets.
1068 * ioext.c (scm_read_line): Free string after Guilifying it.
1069 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.

1077 1997-11-25 Mark Galassi <rosalia@cygnus.com>
1079 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
1080 gh_repl (argc, argv).
1082 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
1084 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
1085 and to invoke scm_shell().
1086 (gh_launch_pad): took out the loading of boot-9.scm from here,
1087 since it is probably best to let the user control that. In fact,
1088 gh_repl() now invokes scm_shell() which does that.
1090 1997-11-23 Mark Galassi <rosalia@cygnus.com>
1092 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()

1112 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
1114 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
1115 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
1117 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
1119 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
1120 configure.in was changed).

1127 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
1129 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
1130 OPORT is an `open' port, not an output port.

1133 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use

1139 scm_close_all_ports_except, scm_set_current_output_port,
1140 scm_set_current_error_port): Likewise
1141 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
1142 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):

1154 Minor problems with substring-related tag changes.
1155 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
1156 exactly what we want to leave in to detect substrings.
1157 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
1158 * tags.h: Fix diagrams and comments describing the S tag bit;
1159 remove vestigial remarks about the D tag bit.
1160 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
1161 * strings.c: Formatting tweaks.
1163 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
1164 variable first; then SCHEME_LOAD_PATH, with a warning message.
1165 (scm_parse_path): New function.
1166 * script.c: Doc fixes.
1168 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1170 Readline support, from Daniel Risacher.
1171 * readline.c, readline.h: New files.
1172 * init.c: #include "readline.h".
1173 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1174 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1175 * Makefile.in: Regenerated.
1176 * scmconfig.h.in: Regenerated, after change to ../configure.
1178 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1180 * gh.h: gh_vector_set -> gh_vector_set_x
1182 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1184 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1185 with the ! -> _x mapping when going from Scheme to C.
1187 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1189 * gh.h (gh_reverse):
1197 (gh_assoc): added these gh_ functions implemented as macros.
1199 * gh_predicates.c (gh_null_p):
1200 (gh_string_equal_p): added these two missing predicates.
1202 * gh_list.c (gh_append):
1207 (gh_set_cdr_x): added these routines as I go through and try to
1208 complete the picture R4RS functions that should be mirrored in the
1211 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1213 * tags.h (scm_tc7_substring): Changed the comment and code to
1214 conform with the changes below. Folks! We have suddenly two new
1215 free tc7 codes!!! Jummy, jummy!
1217 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1219 * Makefile.in: Rebuilt.

1246 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1248 Don't include "mbstrings.h".
1249 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1250 (SCM_SYMBOL_SLOTS): Define as 4.

1275 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1277 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1279 * gh_test_c.c (c_vector_test): some improvements on the vector
1282 * gh.h (gh_vector): this used to exist but do the wrong thing.
1283 Now it (almost) does the right thing, though it takes a list
1284 instead of the individual arguments. I need to see how it could
1286 (gh_list_to_vector): added this function as a macro. Corresponds
1287 to Scheme's (list->vector ...).
1288 (gh_vector_to_list): added this function as a macro. Corresponds
1289 to Scheme's (vector->list ...).
1291 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1292 gh_vector_ref, so that it resembles the Scheme routines more.
1293 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1294 resembles the Scheme routines more.
1295 (gh_make_vector): this used to be (stupidly) called gh_vector().
1296 This is the right name, since it does the same thing as the Scheme
1297 (make-vector ...) procedure.
1299 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1301 * ports.h: #include "libguile/print.h"

1304 Some indentation fixes.
1306 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1307 longer a user field; New field: class_flags.
1309 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
1311 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
1313 * gh_data.c (gh_bool2scm): new function which replaces
1314 gh_int2scmb(), which is now tagged as obsolete.
1316 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1318 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1319 macros should by convention not test for NIMPness.)
1320 (SCM_COERCE_OPORT): Adjust indentation.
1322 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1323 SCM_NIMP test before SCM_PRINT_STATE_P.
1325 * struct.c, struct.h, gc.c: Renamed:
1326 scm_struct_i_layout --> scm_vtable_index_layout
1327 scm_struct_i_vcell --> scm_vtable_index_vcell
1328 scm_struct_i_vtable --> scm_vtable_index_vtable
1329 scm_struct_i_printer --> scm_vtable_index_printer
1330 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1332 * struct.c (scm_print_struct): Use new printer slot; Default
1333 printing: Also output hex code of vtable so that type identity
1334 will be indicated as well.
1335 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1336 Removed struct_printer_var; Removed struct-vtable-offset;
1337 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1338 vtable-offset-user): New constants.
1340 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1341 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1342 If this slot contains a procedure, use that to print structures of
1343 the type represented by this vtable.
1345 * print.c (scm_iprin1): Don't print arguments of macro
1346 transformers. (They are always: exp env.); Bugfix: Unmemoize
1347 transformer source with correct environment.
1349 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1351 Streamlining of call-with-dynamic-root:
1353 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1354 there is now only one catch.
1355 (cwdr_outer_body): Removed.
1356 (cwdr_handler): New function.
1357 (scm_internal_cwdr): New function to perform the function of cwdr
1358 but take args that are more useful to C code. Also, the handler
1359 is now invoked *outside* of the new dynamic root, like the docs
1360 say. We no longer have to catch absolutely all errors, the caller
1361 is responsible for using a handler that does not throw, if he
1363 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1364 * root.h (scm_internal_cwdr): New prototype.
1366 Even more but risky streamlining:
1368 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1369 allocation of the jumpbuf of a root continuation. The changes
1370 below are controlled by it. They are now deactivated.
1371 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1372 the JMPBUF of the scm_rootcont to NULL before returning.
1374 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1375 when they are non-NULL.
1376 (scm_gc_mark): Likewise, mark only when non-NULL.
1378 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1379 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1381 * gc.c (scm_done_malloc): New function.
1382 gc.h (scm_done_malloc): New prototype.
1384 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.

1391 a certain value is acceptable as a port argument.
1392 (scm_print_state_vtable): New variable.
1393 (scm_free_print_state): Set `revealed' field to false.
1394 (scm_iprin1): Call user supplied closure printer with
1395 scm_printer_apply. Print in the traditional way when there isn't
1396 one or when it returns #f.
1397 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1398 Accept a port/print-state pair in addition to just a port.
1399 (scm_prin1): Don't return the print_state to the pool when it has
1401 (scm_printer_apply): Set `revealed' field of print_state to true.
1402 (scm_init_print): Set scm_print_state_vtable.
1403 (print_state_fluid, print_state_fluid_num): Removed.
1405 * throw.h (scm_handle_by_proc_catching_all): New prototype
1406 throw.c (scm_handle_by_proc_catching_all): New function
1408 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1410 * Makefile.in: Regenerated with automake 1.2c.
1412 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1414 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1415 was looping endlessly.
1417 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1419 * strports.c (scm_eval_string): Don't close the port.
1421 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1422 former returns a nice normal integer. (Thanks to Daniel
1425 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1427 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1428 makefile variable as a build parameter called LIBS. The
1429 build-guile program will use this, for the time being.
1430 * Makefile.in: Regenerated.
1432 Thanks to Shiro Kawai:
1433 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1434 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1437 * Makefile.in: Regenerated with automake 1.2a.
1439 * script.c (scm_compile_shell_switches): If we hit the -c or --
1440 arguments, don't set the car of (command-line) to scm_usage_name,
1441 the prettified name of the guile executable; give it the full
1442 path, the way shells usually handle $0.
1444 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1446 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1447 Scheme-level name `array-map' and renamed `serial-array-map' to
1448 `serial-array-map!'.
1450 * backtrace.c: Introduced exception handlers which now enclose
1451 `display-error' and `display-backtrace' so that error reporting
1452 won't get into infinite loops if an error occurs during displaying
1453 of the error. This can very easily happen with user supplied
1454 print call-back routines.
1456 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1458 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1459 the names `serial-array-map' and `array-map' should be removed.)
1461 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1463 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1464 Added #include "objects.h"
1466 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1467 Add #include "feature.h".
1469 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1470 (modinclude_HEADERS): Added objects.h.
1472 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1473 This test is needed at many places in the code and should be
1474 abstracted. (Motivated by the need of this test in libguiletk.)
1476 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1477 (scm_eval_string), load.c (scm_primitive_load,
1478 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1479 Use SCM_EOF_OBJECT_P.
1481 * eval.c (scm_init_eval): Add feature `delay'.
1483 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1485 * scmhob.h: Removed.
1487 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1489 * list.h (SCM_LISTn): New macros. Make list creation in C code
1490 prettier. The idea comes from STk.
1492 * sequences.h, sequences.c, append.h, append.c: Removed. These
1493 files implemented non-R4RS operations which would encourage
1494 non-portable programming style and less easy-to-read code.
1496 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1499 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1500 sequences.h, #include append.h.
1502 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1505 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1507 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1509 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1511 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1513 * eval.c: Added #include "objects.h"
1515 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1518 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1519 adjacent smob numbers.
1521 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1523 * procprop.h: Added declaration of scm_i_inner_name.
1525 * gsubr.c: New global symbol scm_i_inner_name.
1527 * debug.c (scm_procedure_name): Try procedure property
1528 `inner-name' if `name' fails.
1530 * print.c (scm_iprin1): Use scm_macro_name.
1532 * eval.c (scm_m_define): Give names to macros as well; Only the
1533 first top-level definition gives a procedure/macro a name.
1534 Otherwise confusing names can turn up in backtraces.
1535 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1536 `name'; Give names to macros as well.
1538 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1539 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1542 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1544 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1546 (prinmacro): Removed. The code has been moved/merged into print.c
1547 in order to decrease code redundancy. We want macros to print in
1548 a way equivalent to procedures, and it would be silly to duplicate
1549 the required code. (We don't want to maintain two places.)
1550 (macrosmob): Print field is now a NULL pointer.
1552 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1553 scm_macro_transformer): New prototypes.
1554 (scm_tc16_macro): Declared.
1556 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1557 are now printed in a way equivalent to procedures.
1559 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1561 * procs.h (scm_closure_p): Added declaration.
1563 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1565 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1566 Shouldn't pass "heap" as the subr name.
1568 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1570 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1571 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1572 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1573 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1574 SCM_BOOL_T. Any non-false value is true.
1576 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1578 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1579 scm_gensym): Added prototypes.
1581 * symbols.c (scm_gensym): New function. This will speed up
1582 certain types of applications (such as macro systems) which
1583 generate lots of symbols.
1585 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1587 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1589 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1591 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1592 specifier, since (2) or (2 . 3) would cause SEGV.
1593 (scm_transpose_array): more argument checking fixes.
1595 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1597 * Makefile.in: Regenerated.
1599 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1601 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1603 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1605 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1607 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1609 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1610 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1613 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1614 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1615 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1616 scm_array_p, scm_array_rank, scm_array_dimensions,
1617 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1618 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1619 scm_array_prototype): Added case scm_tc7_wvect.
1621 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1623 * errno.h: prototype for scm_strerror.
1624 * error.c (scm_strerror): new procedure.
1626 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1628 * list.c (scm_list_append_x): Allow non-pair as last argument.
1629 This is consistent with the R4RS append and is probably the
1630 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1632 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1634 * stime.h: prototype for scm_times.
1635 * stime.c (scm_times): new procedure.
1636 * ioext.c (scm_fseek): if the first argument is a file descriptor
1638 (scm_ftell): if the first argument is a file descriptor call lseek
1640 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1641 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1643 (scm_chown): if the first argument is a port or file descriptor,
1645 (scm_truncate_file): new procedure.
1646 Add DEFER/ALLOW INTS to a few other procedures.
1647 (scm_fsync): new procedure.
1648 (scm_open_fdes): new procedure.
1649 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1651 (scm_fcntl): the first argument can now be a file descriptor. The
1652 third argument is now optional.
1654 * posix.c (scm_execl, scm_execlp): make the filename argument
1655 compulsory, since omitting it causes SEGV.
1656 (scm_sync): return unspecified instead of #f.
1657 (scm_execle): new procedure.
1658 (environ_list_to_c): new procedure.
1659 (scm_environ): use environ_list_to_c. disable interrupts.
1660 (scm_convert_exec_args): take pos and subr arguments and
1661 improve error checking.
1663 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1665 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1666 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1667 argument to SCM_ASSERT. Furthermore, the name of the function
1668 should be passed as first argument when signalling
1669 SCM_WNA. (Thanks to Thomas Morgan)
1671 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1672 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1673 dispatches on the number of actual args has a default case
1674 reporting an internal error. This is a vestige from a version
1675 that mallocated a SCM vector to hold the arguments. In the
1676 current version this check is too late: if it ever happens we will
1677 have already overstepped the bounds of the array.
1679 Also, the patch [...] adds a check for too many actual arguments."
1681 mdj: Removed check for "internal programming error".
1683 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1685 * gh_io.c (gh_write): New function.
1687 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1688 throw.c (scm_internal_stack_catch): New sibling to the other catch
1689 functions. Code moved from gh_eval.c.
1690 throw.h: Added header.
1691 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1692 scm_internal_stack_catch.

1696 * ioext.h: fix up prototypes.
1697 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
1698 Scheme name is now dup->fdes.
1699 (scm_dup_to_fdes): make the second argument optional and
1700 fold in the functionality of scm_primitive_dup.
1701 (scm_primitive_dup): deleted.
1703 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1705 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1706 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1707 ultrix are defined. Use setvbuf instead of setbuf.
1708 (scm_setvbuf): new procedure.
1709 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1710 (scm_setfileno): moved from ioext.c.

1722 state as nested data while they are printed.
1723 (print_state_fluid, print_state_fluid_num): New variables.
1724 (scm_init_print): Initialize them.
1725 (scm_iprin): If print_state_fluid carries a print_state, use that
1726 instead of creating a new one.
1727 (scm_printer_apply, apply_stub, struct apply_data): New
1728 definitions to help with calling printer functions written in
1730 * print.h (scm_printer_apply): New prototype.

1743 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1744 SCM_ASSERT: arg comes before pos.
1746 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1748 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1749 to a list of length zero correctly.
1751 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

1767 * ioext.h: removed scm_duplicate_port prototype.
1769 * ioext.c (scm_primitive_dup2): return the new file descriptor
1770 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
1772 (scm_fdopen): bug fix: don't try to make port unbuffered until its
1773 stream has been set.
1774 (scm_duplicate_port): deleted, there's now an implementation in
1776 (scm_primitive_dup2): do nothing if newfd == oldfd.
1778 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
1780 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

1786 * fluids.c (next_fluid_num): don't do
1787 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
1789 * ports.h: prototypes too.
1790 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
1792 * fports.h: prototype too.
1793 * fports.c (scm_evict_ports): moved from ioext.c.
1795 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
1797 * ports.c (scm_close_port): return a boolean instead of unspecified.
1798 throw an error if an error other than EBADF occurs.
1800 * filesys.h: scm_close prototype.
1801 * filesys.c (scm_close): new procedure, can close file descriptors
1802 and ports (scsh compatible).
1804 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
1807 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
1809 * fluids.c, fluid.h: New files.

1826 * dynl.c (free_dynl_obj): New function to free the dynamic object
1827 data. (dynl_smob): Use it.
1828 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
1829 the dynamic object data below the linking of the object to avoid
1830 memory leak when the linking code throws an error. Now the code
1831 leaks a whole dynamically linked library when must_malloc throws,
1832 but that should be much less likely.
1834 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
1836 Changes to compile under gnu-win32, from Marcus Daniels:

1874 think this is left over from the (eq? '() #f) days.
1876 * read.c (recsexpr): Give this a dummy definition if
1877 DEBUG_EXTENSIONS isn't #defined.
1879 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
1881 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

1891 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
1892 alloca.lo will be included in @LIBLOBJS@. Something better than
1893 this should be possible.
1894 * Makefile.in: Regenerated.
1896 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>

1906 have to do this explicitly. Also, if regexp/basic is supplied, then
1907 turn off REG_EXTENDED.
1908 (scm_init_regex_posix): New regexp/basic symbol.
1909 (REG_BASIC): #define this if it is not already present.

1932 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
1934 (scm_init_regex_posix): Define constants for the REG_mumble flags;

1952 * root.c: Establish a reliable catch-all handler for the new root.
1953 After all the Scheme handler function might signal an error too,
1954 and we don't want to lose that.

1956 (cwdr_outer_body): New function, to establish the user's handler,
1957 and pass control to cwdr_inner_body.

1968 across this. Only works on GCC. Otherwise, we hope for the best.
1969 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
1970 the feeling that real thread systems will not need this...
1972 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
1974 Try to detect when people are using one version of libguile and a

1986 primitive definitions under their Scheme names.
1988 * Makefile.am (libguile_la_LDFLAGS): Update library version to
1989 1:2. Helps avoid confusion between installed and uninstalled libs.
1991 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
1994 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
1995 backslash from definition; this should be used like: GDB_INTERFACE;

1999 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
2000 new port unbuffered until its stream has been set.
2002 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
2004 * ports.h: new prototype.
2005 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
2007 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
2009 Make things compile neatly under Sun's C compiler.
2010 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
2011 * extchrs.c (xmbtowc): Make the second arg a normal char, not
2012 unsigned, because that's what the ANSI function takes.
2013 * extchrs.h (xmbtowc): Corresponding change to prototype.
2014 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
2016 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
2017 argument plain char *.
2018 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
2020 * tag.c (scm_tag): Remove unreachable statement.
2021 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
2022 top of the word, it should be unsigned.
2024 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
2025 is defined, to avoid warnings; it's only used in the
2026 conflict-checking code. Which might go away anyway.
2027 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
2028 conditionals; put the label definition in an #if too, to stifle
2031 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
2032 ChangeLog-threads in the distribution.
2033 * Makefile.in: Regenerated.
2035 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2037 * guile-snarf.in: Changed regexp to support CPPs that insert
2038 whitespace between lexical tokens (which munges the `%%%' snarf
2041 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
2043 * load.c (scm_init_load_path): Append $(datadir)/guile to
2044 %load-path, so modules do not have to be installed in Guile's
2045 current version directory.
2047 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
2049 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
2050 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
2051 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
2052 call the sysdep functions with deferred ints.
2053 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
2054 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
2055 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
2058 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
2061 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
2063 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
2065 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
2067 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
2070 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
2072 * eval.c (scm_lookupcar1): New procedure to cope with a race
2073 condition during lookup (when using threads).
2074 (scm_lookupcar): Implement in terms of scm_lookupcar1.
2075 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
2078 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
2080 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
2081 supplied. (Change from Tim Pierce.)
2083 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
2085 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
2086 23:47:01 1997" changelog: Slots are now initialized with `#f' by
2087 default and not `()'. `#f' is the canonical non-value in Scheme,
2090 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2092 * struct.c (struct_printer): New variable that holds a handle on
2093 the Scheme variable *struct-printer*. This variable can be set by
2094 Scheme code to override the printing of structures.
2095 (scm_print_struct): If struct_printer is set, call it. If it is
2096 not set, or returns #f, print the structure in the old fashion.
2097 Include "eval.h" for scm_apply.
2099 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
2101 * struct.c (scm_struct_ref, scm_struct_set_x): Use
2102 scm_struct_i_n_words to get the number of fields, not
2103 -scm_struct_n_extra_words.
2105 On the route to fancier struct printing:
2106 * struct.c (scm_print_struct): New function to print a structure.
2107 Include "genio.h" to support it. This function doesn't do
2108 anything interesting right now, but I think it should be here
2110 * struct.h: Include "print.h" and add prototype for
2112 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
2113 print structures ourself.
2115 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2117 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
2118 before applying the handler in case it doesn't return.
2120 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
2122 * scmsigs.h, async.h: updated.
2124 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
2127 * posix.c (scm_uname): interpret only negative values as an error.
2128 Solaris normally returns a positive value.
2130 * script.c (scm_compile_shell_switches): if we are not going into
2131 an interactive repl, set scm_mask_ints to zero so that asyncs can
2134 * simpos.c (scm_system): don't ignore/unignore signals around
2137 * posix.c (scm_open_pipe): don't ignore/unignore signals around
2140 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
2141 done in boot-9.scm instead.
2143 * scmsigs.c, async.c: Major rewriting of signal handling code.
2144 (scm_sigaction): new procedure.
2145 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
2147 (scm_raise): return unspecified, throw error on failure.
2149 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2151 * regex-posix.c (scm_init_regex_posix): Register the "regex"
2152 feature, to help boot-9.scm decide whether to import the regex
2155 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2157 * eval.c: Include scmconfig.h at the beginning of the file so that
2158 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
2161 * regex-posix.c: #include "_scm.h" before conditionally #including
2162 <regex.h>; the former defines HAVE_REGCOMP.
2164 * regex-posix.c: #include <regex.h> conditionally, so the file is
2165 CPP'able (for dependency scanning) even on systems that don't have
2168 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2170 Add new R4RS-compliant syntax for keywords.
2171 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2172 regardless of the setting of the `keywords' read option.
2173 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2174 can be re-read no matter what the setting of the `keywords' read
2177 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2179 Add support for POSIX regular expressions.
2181 * regex-posix.c, regex-posix.h: New files. (Some code
2182 is taken liberally from rx/rgx.c in the old Guile dist.)
2184 * init.c: Include regex-posix.h.
2185 (scm_boot_guile_1): Call scm_init_regex_posix.
2187 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2188 Add regex-posix.[ch] sources.
2189 * Makefile.in: Regenerated.
2191 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2192 to do this automatically? It didn't for me, bleh.)
2194 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2196 * fports.c (print_pipe_port): New function.
2197 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2198 latter doesn't even take the right arguments.
2200 * Makefile.am: Increment shared lib revision number. I think
2201 sometimes the uninstalled Guile finds the installed shared lib;
2202 Gord says doing this might help. As things turned out, I can't
2203 say whether it does.
2204 * Makefile.in: Regenerated.
2206 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2207 passing it as the closure argument to scm_boot_guile. (Bill
2210 * ports.c (print_void_port, putc_void_port, puts_void_port,
2211 write_void_port, flush_void_port, getc_void_port, close_void_port,
2212 noop0): Use ANSI prototypes instead of K&R declarations, so the
2213 initialization of void_port_ptob gets aggressively type-checked.
2214 Fix arguments of print_void_port and write_void_port. (Bill

2248 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2250 * script.c (scm_find_executable): Use prototype-style definition
2251 here; apparently it's not quite right to have const in a prototype
2252 and then use a K&R declaration. I wonder if stuff like this will
2253 go away if we compile with -Wrequire-prototypes, or whatever that
2254 is... (Bernard URBAN)
2256 * scmhob.h: New text from Bernard URBAN.
2258 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2260 * script.c: Don't #define const on hpux. Configure takes care of
2261 this. (Thanks to Larry Schwimmer.)
2263 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2264 decide whether to #include <unistd.h>, instead of listing a bunch
2265 of systems. Don't #include stdio twice. Removed dyked-out
2266 definition of scm_find_impl_file.
2268 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2270 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2271 library version info to 1:0.

2278 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2279 throw.c: Update copyright years; these files have been worked on
2280 significantly in 1997, but only had copyright years for 1996.
2281 Also, change name of copyright holder on some from Mikael
2282 Djurfeldt to Free Software Foundation; he has signed papers
2283 assigning the changes to the FSF.
2285 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2286 reason not to give the user the option.
2288 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2289 Return #f on end-of-file when scanning table (i.e. when called
2290 with no arguments). Try to catch errors, when we can.
2291 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2293 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2294 external declarations. These are useful.
2296 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2298 * posix.c: don't include <sys/select.h> or define macros for
2299 select, since they were not used in this file.
2301 * filesys.c (scm_select): make the fifth parameter microseconds,
2302 not milliseconds. let the fourth parameter be either a real value
2303 or an integer or #f. The first, second and third arguments can
2304 now be vectors: the type of the corresponding return set will be
2306 (set_element, get_element): new static procedures.
2308 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2310 * strports.c (scm_eval_string): New function.
2311 (scm_eval_0str): Trivially re-implemented in terms of
2313 * strports.h (scm_eval_string): New extern decl.
2315 * net_db.c (h_errno): Add extern decl for this.
2317 * fports.c (local_pclose): New function.
2318 (scm_pipob): Use it in the initializer here.
2321 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2322 Use a meaningful error message when signalling an error. For
2323 this, scm_gethost must check h_errno rather than errno.
2325 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2327 * Makefile.in: Regenerated, using automake-1.1p.
2329 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2331 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2332 not SCM_UNSPECIFIED.
2334 * script.c (scm_compile_shell_switches): don't append (quit) if
2336 (scm_shell): call scm_exit_status and exit on the result of the
2339 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2341 Ensure that shared substrings are handled properly when passed to
2342 a system call or other foreign function. Many thanks to Tim
2344 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2345 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2346 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2347 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

2359 SCM_COERCE_SUBSTR to make sure shared substrings are
2362 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2364 * error.c (scm_error): Add newline to error message.
2366 * init.c (scm_init_standard_ports): Doc fix.
2368 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2370 * dynl-shl.c: Completely replaced with new code from Bernard
2373 * script.c (scm_ice_9_already_loaded): New variable.
2374 (scm_compile_shell_switches): Use it.
2376 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2378 * filesys.c (scm_input_waiting_p): add missing third argument to

2382 calling gmtime in case they share a buffer.
2383 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2386 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2388 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2390 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2392 * Makefile.am (check-local): New target, which causes 'make check'
2393 to run gh_test_c and gh_test_repl, with some trivial input.
2394 * Makefile.in: Rgnrtd.
2396 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2398 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2401 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2403 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2404 sure how this was supposed to work.
2405 (scm_async_click): don't send SCM_TICK_SIGNAL.
2406 (scm_init_async): don't initialize %tick-thunk.
2408 * the following change doesn't affect the Scheme interface:
2409 gc-thunk is called at the end of garbage collection. however it's
2410 no longer implemented by pretending it's a signal.
2412 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2413 system async corresponding to scm_gc_thunk.
2414 * async.h: declare scm_gc_async.
2415 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2416 gc-thunk directly, instead of going through a signal handler.
2417 (scm_gc_async): new variable, points to the GC system-async.
2418 (scm_init_async): save the GC async as scm_gc_async instead
2419 of using system_signal_asyncs.
2420 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2422 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>

2425 Don't screw up if we're interrupted.
2426 * Makefile.in: Regeneradet.
2428 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2430 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2432 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2433 we're not using AM_INIT_GUILE_MODULE any more.
2434 * Makefile.in: Reneregated.
2436 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>

2446 Changes for reduced Guile distribution: one configure script,
2448 * configure.in, configure: Removed.
2449 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2450 real configure script lives.
2451 * Makefile.in, scmconfig.h.in: Regenerated.
2453 * init.c: #include "script.h", to get prototype for script.c's

2458 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2459 scm_must_malloc, not raw malloc.
2461 * script.c (scm_compile_shell_switches): Dyke out debugging output
2464 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2466 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2468 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2469 system has them. Hope this is safe. Previously
2470 sys/timeb.h was included if HAVE_FTIME was defined or if
2471 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2472 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2474 * ioext.c (scm_setfileno): add missing third argument to
2475 scm_misc_error call.
2477 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2479 * eq.c (scm_equal_p): Correctly compare strings of different
2480 varieties. (Thanks to Tim Pierce.)
2482 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2484 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2485 #! block comment must occur on a line all by itself.
2487 Move most of the guts of shell command processing into libguile,
2488 so guile.c can be very small (and eventuallly auto-generated. (I
2489 mean, generated mechanically, not self-generated. Hmm.))
2490 * guile.c, script.c, script.h: New source files.
2491 * init.c (scm_boot_guile_1): Call scm_init_script.
2492 * libguile.h: #include "script.h".
2493 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2494 targets, for new executable.
2495 (libguile_la_SOURCES): Mention script.c.
2496 (modinclude_HEADERS): Add script.h.
2497 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2498 not dynamic linking is enabled. This is because we're generating
2499 executables now. Move CY_AC_WITH_THREADS call after those, so the
2500 values of cy_cv_threads_libs captures the libs chosen above.
2501 * Makefile.in, configure, aclocal.m4: Regenerated.
2503 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2504 We don't maintain this interface any more, and it just confuses
2507 * alloca.c: #include <scmconfig.h>, not <config.h>.
2508 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2509 it'll get included in disties.
2511 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2513 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2514 be distributed, because they confuse people.
2515 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2517 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2519 * configure.in: check for presence of gethostent (not present on
2520 OpenBSD by default).
2521 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2522 * configure, scmconfig.h.in: Regenerated.
2524 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2526 * backtrace.c (scm_backtrace): Split message string across
2527 newlines properly. GCC is more tolerant of this than other

2532 Merge threads directory into libguile.
2533 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2534 threads.h: New source files.

2536 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2538 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2539 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2540 coop-threads.c.cygnus, coop-threads.h.cygnus.
2541 * configure.in: If we're using threads, include threads.o in
2543 * _scm.h, libguile.h: threads.h lives in this directory now.
2544 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2545 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2546 currently used, but brought along for information's sake.
2547 * ChangeLog-threads: log from old 'threads' directory.
2548 * Makefile.in, configure: Rebuilt.
2550 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2552 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2555 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2557 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2559 Merge GH interface library into libguile.
2560 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2561 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2562 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2563 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2565 (EXTRA_libguile_la_SOURCES): ... here.
2566 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2567 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2568 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2569 New variables, describing how to build the gh test programs.
2570 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2571 build the test programs, and we probably should have been linking
2572 libguile.la against them all along, to support AIX shared libs.
2573 Add cflags for threads to CFLAGS; add libs for threads to new
2574 variable THREAD_LIBS, used in Makefile.am.
2575 * ChangeLog-gh: log from old `gh' subdirectory.
2576 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2578 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2580 * acconfig.h: Undo change of Apr 9; including the definition of
2581 PACKAGE in the guile headers conflicts with applications' own
2583 * scmconfig.h.in: Regenerated.

2594 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2596 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2597 have S_IFSOCK. This is the case under Ultrix.
2599 * posix.c (scm_status_exit_val, scm_status_exit_val,
2600 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2601 Ultrix versions of WIFSTOPPED, etc., which assume that their
2602 arguments are lvalues (hmm).
2604 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2606 * eval.c: Doc fixes.
2608 * throw.c: Doc fixes; rearranged.
2610 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.

2614 * acconfig.h: Added entry for PACKAGE.
2615 * scmconfig.h.in: Regenerated.
2617 Changes to work with automake-1.1n, which has better libtool support.
2618 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2619 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2621 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2623 * Makefile.in: Rebuild.
2625 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2627 * stime.c (scm_mktime): take an optional zone argument.
2628 (scm_localtime): check putenv return value.
2629 (scm_strftime, scm_strptime): moved from posix.c. move #include
2631 stime.h, posix.h: update prototypes.
2632 (bdtime2c, setzone, restorezone): new static procedures.
2633 (scm_mktime, scm_strftime): use them.
2634 (scm_strftime): don't call mktime before strftime. Use
2635 filltime for return value.
2636 (filltime): convert NULL zname to #f.
2637 (scm_strptime): return a count of characters consumed, not
2638 the remaining string.

2642 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2643 (scm_mktime): likewise.
2645 Uncomment localtime and mktime.
2647 * configure.in: add AC_STRUCT_TIMEZONE.

2651 * stime.c (scm_init_stime): don't define ticks/sec.
2652 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2653 return value problem and is still portable.)
2655 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2657 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2658 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2659 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2660 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2661 cpp_err_symbols.c): Corresponding changes.
2662 * Makefile.in: Regenerated.
2664 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2666 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2667 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2668 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2669 * putenv.c: new file, from sh-utils 1.12.
2671 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2672 since allocation isn't for Scheme objects.
2673 (scm_putenv): copy strings before placing in the environment.
2675 * stime.c (scm_current_time): throw an error if time returns -1,
2676 instead of returning #f.
2677 (scm_get_internal_real_time, scm_get_internal_real_time): use
2678 scm_long2num for return value instead of SCM_MAKINUM.
2680 * stime.h: prototypes updated.
2682 * stime.c (scm_time_in_msec): apparently unused, deleted.
2684 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2686 * configure.in: check for gettimeofday.
2688 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2689 which may be more usefully portable than a gettimeofday interface.
2691 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2693 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not

2697 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2699 * stime.c (filltime): recovered static procedure.
2700 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from

2704 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2706 * posix.c (scm_mknod): split the mode argument into type and perms
2707 arguments, like the extra fields returned by stat.
2709 * fports.c (scm_pipob): set the close, free and print procedures.
2710 (scm_close_pipe): new procedure.
2712 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2713 define them in boot-9.scm
2715 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2717 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2718 wan't defined. Don't include fd.h.
2720 * Previously fd.h was regenerated whenever configure was run,
2721 forcing a couple of files to be recompiled.
2723 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2724 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2725 Check for _fileno as well as _file.
2727 * ioext.c: don't fd.h.
2728 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2731 * Change the stratigy for getting information about errno
2732 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2733 generating lists of symbols during the build process, which will
2734 not always work, include comprehensive lists in the distribution.
2735 To help keep the lists up to date, the "check_signals" and
2736 "check_errnos" make targets can be used.
2738 * configure.in: don't check for a command to extract errno codes.
2739 * Makefile.am: update file lists, remove errnos.list and errnos.c
2740 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2741 check_errnos targets.
2742 (CLEANFILES): remove errnos.c and errnos.list, add
2743 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2744 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2745 * errnos.default: deleted.

2747 * cpp_errno.c: renamed from errnos_get.c.
2748 * cpp_err_symbols, cpp_sig_symbols: new files.
2749 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2750 * error.c (scm_init_error): #include cpp_err_symbols instead of
2752 * posix.c (scm_init_posix): don't intern signal symbols. #include
2755 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2757 * strop.c (scm_i_index): allow the lower bound to be equal to the
2758 length of the string, so a null string doesn't always give an error.
2760 * posix.h: new prototypes.
2761 * posix.c (scm_status_exit_val, scm_status_term_sig,
2762 scm_status_stop_sig): new functions, as in scsh. They break down
2763 process status values as returned by waitpid.
2765 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2767 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2768 configure doesn't know about it.
2770 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2772 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2774 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2775 which defines C variables with global linkage.
2777 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2779 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2782 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2784 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2785 has time to check why this doesn't work well with continuations.
2787 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2789 * Fix shell syntax error; some shells won't tolerate
2790 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2792 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2794 * posix.c (scm_uname): throw an error if uname fails instead
2797 * error.h (scm_errno, scm_perror): obsolete prototypes removed.

2806 * acconfig.h: Removed PACKAGE.
2808 * scmconfig.h.in: Regenerated.
2810 * snarf.h: g++ says it's non-portable not to specify the first
2811 argument in a varargs declaration. I introduced the first
2812 argument by using preprocessor conditionals.
2814 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
2816 * ioext.c (scm_read_delimited_x): use RO string macros for delims.

2846 * error.h: prototype for scm_error_scm.
2848 * error.c (scm_error_scm): new procedure, reimplements scm-error
2849 in C and uses scm_error.
2851 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2853 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
2854 pointer to the Scheme variable read-hash-procedures and intern it
2855 in scm_init_read. Modify scm_read_hash_extend and
2856 scm_get_hash_procedure to use the pointer.
2858 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2860 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
2861 (SCM_KEYWORD_STYLE): defined.
2863 * read.c (scm_read_opts): add a keywords option. This isn't a
2864 boolean option, in case someone wants to add support for DSSSL
2866 Setup scm_keyword_prefix symbol.
2867 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
2869 I've left keyword support disabled by default, since it doesn't
2870 seem to break the module system and it gives R4RS standard behaviour.
2871 It can be reactivated with (read-set! keywords 'prefix).
2873 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2875 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS

2887 * read.c (scm_init_read): intitialise scm_read_hash_procedures
2888 (idea from Mikael: make it a pair so scm_permanent object only
2890 (scm_read_hash_extend): don't call scm_permanent_object.
2891 (ideas from Mikael): if chr is already in the list, replace its
2892 procedure instead of appending it again. If proc is #f, remove
2894 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
2896 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.

2925 * read.c (scm_read_token): if case_i, downcase ic before doing
2928 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2930 * configure.in: Added configuration option `guile-debug'.
2931 Configure with --enable-guile-debug if you want a bunch of extra
2932 functions used for debugging when developing Guile.
2934 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
2936 * procs.c (make-cclo): New undocumented debugging procedure: Make
2937 compiled closure with internal procedure PROC and length LENGTH.
2938 Only compiled if GUILE_DEBUG is defined.
2940 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
2942 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
2944 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
2946 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
2947 with 3 or more args internally to the evaluator.
2949 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2951 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
2952 with 3 or more args internally to the evaluator. This is mainly
2953 because we don't want to pass entry and exit points of the
2954 debug support twice, but it also seems to increase the speed of
2955 the evaluator for such calls (e. g. (+ 1 2 3)).
2957 * backtrace.c (scm_display_application): New procedure:
2958 display-application; Set fancy printing parameters individually
2959 for different types of display (backtrace, error, application).
2960 (These should of course be customizable!)
2962 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
2963 clear the CHECK-flags.
2965 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2967 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
2969 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2971 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
2972 from pairs with a GLOC in the car.
2974 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
2975 otherwise `symbol-hash' will behave badly.
2976 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
2977 we get segmentation fault!
2979 * symbols.c: Added #include "weaks.h". New functions:
2980 `builtin-bindings' and `builtin-weak-bindings'. (These will be
2981 moved to an extraneous library when we split libguile.)
2983 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2985 * filesys.c (scm_stat): stat now takes fport arguments too as
2986 documented in the manual.
2988 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2990 * debug.c (scm_single_step): Bugfix: Call continuation with
2991 scm_call_continuation instead of throwing to it.
2993 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
2995 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
2996 argument wasn't declared to be optional.
2998 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3000 * stime.c (scm_init_stime): Add feature "current-time".
3002 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3004 * throw.h: prototype for scm_exit_status.
3005 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
3006 args to derive an exit status. Allows (quit) to work from a
3008 (scm_exit_status): new function.
3011 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3013 * eval.c (scm_deval): Removed some old code.
3014 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
3016 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
3019 * symbols.c (msymbolize): Bugfix: Must initialize property list to
3022 * procs.c: Introduce the existent C function scm_thunk_p at the
3023 Scheme level as well.
3025 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3027 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
3028 used from C to easily lookup the value of a symbol in the current
3031 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3033 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
3034 scm_init_unif in this file. This will also fix a previous problem
3037 * configure.in: Added AM_MAINTAINER_MODE
3039 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3041 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
3044 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3046 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
3047 source files that are not always included in libguile but should
3048 have their dependencies calculated by automake. This variable is
3049 recognized by automake, no further magic is needed.
3050 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
3051 to deal exclusively with *.lo files, as it seems. The *.o files
3052 are built automatically when the corresponding *.lo file gets
3055 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
3057 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
3060 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
3062 * unif.c (scm_array_set_x): minor change to argument error checking.
3064 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
3066 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
3067 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
3068 They should only be included in the library at configure.in's
3070 (libguile_la_LDADD): Include the appropriate .lo files here.
3071 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
3072 so we know when to build them (and their .lo bretheren).
3073 * configure.in (LIBLOBJS): New substituted variable. We let
3074 configure decide which .o files to include in LIBOBJS, and then
3075 put the corresponding list of .lo files in LIBLOBJS. The latter
3076 is what we pass to libtool.
3077 * Makefile.in, configure: regenerated.
3079 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
3081 * symbols.c (scm_sysintern0): New function. Contains the core of
3082 old scm_sysintern but doesn't take a second value argument.
3083 (scm_sysintern): Now uses scm_sysintern0.
3084 (scm_sysintern_no_module_lookup): Renamed to
3085 scm_sysintern0_no_module_lookup and doesn't take a second value
3086 argument any longer.
3088 * symbols.h (scm_sysintern0: Added declaration.
3090 * options.c (scm_init_opts): Use scm_sysintern0 instead of
3091 scm_sysintern when interning option keys. Otherwise we risk
3092 destroying the values of already interned variables.
3094 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
3095 scheme-level boolean (use SCM_NFALSEP).
3097 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
3099 (scm_backtrace): New function. (C version of old function from
3100 boot-9.scm) Motivation: Make it possible to display backtraces
3101 without depending on boot-9.scm. (I'm uncertain if this
3102 motivation is good enough...)
3104 * root.h (scm_root_state): Add member the_last_stack_var.
3105 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
3107 * root.c (mark_root): Mark scm_the_last_stack_var.
3109 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
3112 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
3114 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
3115 1. mark_lazy_catch didn't mark the smob.
3116 2. Both functions above have standard variants:
3117 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
3118 free_lazy_catch --> scm_free0.
3120 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
3122 * throw.c (scm_internal_lazy_catch): New function.
3123 (scm_lazy_catch): Rewritten to use it.
3124 (scm_ithrow): Handle the new lazy catch representation.
3125 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
3126 that doesn't have a jmpbuf is a lazy catch clause.
3127 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
3128 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
3129 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
3131 (scm_init_throw): Register the new lazy-catch smob type.
3132 * throw.h (scm_internal_lazy_catch): decl for new function.
3134 * throw.c (scm_internal_catch): Doc fixes.
3136 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
3137 configure.in. Including this might cause problems if applications
3138 that link against libguile include their own copies of alloca, but
3139 if they're using autoconf, they should be adding libguile to LIBS
3140 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
3141 the copy in libguile, and things will be okay. (I think.)
3143 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3145 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
3147 strop.h: move prototypes too.
3149 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
3151 * posix.c (scm_init_posix): don't intern EINTR since it's now done
3154 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
3155 etc. I deleted them from filesys.c long ago, but didn't
3156 notice they were here too (although ineffective since
3157 sys/stat.h wasn't included).
3159 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
3161 * eval.c: Don't define alloca in GCC case. gcc will automatically
3162 use __builtin_alloca if appropriate.
3164 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3166 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3167 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3168 that values of automatic variables are preserved. See comments
3169 for safe_setjmp for details.
3171 Change from Thomas Morgan:
3172 * variable.c: Include eq.h.
3173 (var_equal): New function.
3174 (variable_smob): Use var_equal as the discriminator for variables.
3176 * throw.c (s_throw): Remove extraneous declaration.
3178 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3179 * eval.c: Add necessary CPP cruft to support that.
3180 * configure, Makefile.in, scmconfig.h.in: regenerated.
3182 Change from Thomas Morgan:
3183 * procprop.c (scm_procedure_properties): Convert the Scheme
3184 boolean returned by scm_procedure_p into a C boolean before using
3185 it as a condition for SCM_ASSERT.
3186 (scm_procedure_property): Likewise.
3188 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3189 indications of Unixness.
3192 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3194 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3196 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3198 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3199 "unknown # object" error messages.
3201 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3202 (scm_i_index) and declare it static. Add a 'direction' argument
3203 to indicate what way the search should go.
3204 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3206 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3207 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3209 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3211 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3213 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3214 to avoid clash with various scsh forks.
3216 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3218 The following two changes (ramap.c, throw.c) are motivated by the
3219 apparent unportability of forward declarations of static arrays of
3220 the form `static foo bar[];'.
3222 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3223 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3225 * throw.c (scm_throw): Moved above scm_ithrow.
3227 * options.h: Removed the extern declarations of scm_yes_sym and
3228 scm_no_sym since these are static.
3230 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3232 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3234 * Makefile.am: remove AWK=@AWK@.
3235 Add a rule for generating errnos.list.
3236 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3238 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3239 don't extract errnos, just set a variable (avoids the
3240 need to recompile error.c just because configure is run.)
3242 * unif.h: update prototypes.
3243 * unif.c (scm_uniform_array_read,write): change the offset and
3244 length arguments to start and end, for consistency.
3246 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3248 * ioext.h: update prototypes.
3249 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3250 scm_read_line_x, it's a more general procedure using an
3251 interface from scsh. read-line and read-line! are now defined
3253 Note that the new read-line trims the terminator
3254 by default, previously it was appended to the returned string. An
3255 optional argument specifies how to process the terminator (scsh
3256 compatible). For the old behaviour: (read-line port 'concat).
3257 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3258 returns a pair, but is converted to multiple values if the scsh
3261 socket.h: update prototypes.
3262 * socket.c (scm_recvfrom): for consistency with other procedures,
3263 take start and end as separate optional arguments.
3264 (scm_recv, scm_recvfrom): don't allow the second argument
3265 to be a size, only a buffer. Change the scheme names to
3266 recv! and recvfrom!. Don't return the buffer.
3268 * ioext.h, posix.h: move prototypes too.
3269 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3270 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3271 "read.h" and "unif.h".
3272 * ioext.c: include "chars.h"
3274 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3276 * dynl.c: The dynamic linking and module registration functions
3277 are now defined even when dynamic linking is not available for the
3278 host system. Some of their functionality can be done without
3279 dynamic linking; when it's really needed, they throw errors.
3281 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3283 * configure.in: Only define DYNAMIC_LINKING when one of the system
3284 dependent functions is detected.
3285 * dynl.c (scm_dynamic_func): New function to get the address of a
3286 function in a dynamic object.
3287 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3288 produced by scm_dynamic_func as the thing to call.
3290 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3292 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3293 (scm_register_module_xxx, scm_registered_modules,
3294 scm_clear_registered_modules): New functions.
3296 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3298 * symbols.c (scm_sysintern): Renamed to
3299 scm_sysintern_no_module_lookup.
3300 (scm_sysintern): New function to take the place of the old
3301 scm_sysintern. It uses the current toplevel lookup closure to give
3302 the symbol its value. This is a temporary hack to put packages
3303 like gtcltk into their own module.
3304 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3305 us whether `scm_top_level_lookup_closure_var' has been initialized
3307 * eval.c (scm_init_eval): Set it.
3309 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3311 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3312 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3314 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3316 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3317 scm_sys_dup): deleted: FD capability will be added to other
3319 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3320 scm_fd_free, fd_smob, scm_intern_fd.
3321 (scm_open): renamed from scm_sys_open. Return a port instead of
3322 an FD object. Make the mode argument optional.
3323 (scm_sys_create): deleted, it's just a special case of open.
3324 (scm_init_filesys): move interning of constants O_CREAT etc.,
3325 here (were previously using SCM_CONST_LONG macro).
3326 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3328 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3329 include "fports.h" and <stdio.h>
3330 (scm_stat, scm_select): don't support FD objects.
3332 * error.h: adjust scm_syserror_msg prototype.
3333 * error.c (scm_syserror_msg): take an extra argument for errno.
3334 Using the global value didn't always work, since it could be
3335 reset by procedure calls in the message or args arguments.
3337 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3338 I don't understand why the check was there (and what about the
3341 * strop.c (scm_string_copy): allow shared substrings to be copied.
3343 * unif.h: corresponding change to prototypes.
3344 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3345 recognize two new optional arguments: offset and length. Allow
3346 the port argument to be an integer (file descriptor, for scsh).
3347 Include <unistd.h> for "read" prototype.
3349 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3351 * socket.c: don't include filesys.h.
3353 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3355 * Makefile.am: add AWK=@AWK@ (?)
3357 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3359 Add a rule to generate errnos.c from errnos.
3360 * error.c (scm_init_error): include errnos.c.
3361 * errnos_cnvt.awk: new file, converts the list of errno codes to
3363 * errnos_get.c: new file.
3364 * errnos.default: new file, contains errnos to try if they can't
3365 be extracted from errno.h.
3366 * configure.in: if using GCC, try and extract errno codes from
3370 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3372 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3373 * Makefile.am: Made libguile into a libtool library.
3374 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3375 Set libtool_libs to indicate that libguile is a libtool library.
3376 See guile/ChangeLog for details.
3377 * .cvsignore: ignore "*.lo", the libtool library objects.
3379 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3381 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3382 use htons in getservbyport argument.
3384 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3386 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3387 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3390 * objprop.c (scm_object_property): No need to take the CDR of the
3391 value returned by scm_object_properties, since Aug 20 change.
3393 * configure.in: When checking for struct linger, #include
3394 <sys/types.h> as well as <sys/socket.h>. I've never known
3395 <sys/types.h> to cause any portability problems, and Solaris's
3396 <sys/socket.h> needs it.
3397 * configure: Rebuilt.
3399 I think the Sun compiler has chosen a perverse way to interpret
3400 ANSI declarations combined with K&R definitions. We'll
3401 appease it a little bit. But when it invades France, we fight.
3402 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3403 * print.h (scm_iprlist): Here too.
3404 * numbers.c (scm_divbigdig): Change definition to match
3405 declaration in numbers.h.
3406 * unif.c (scm_makflo): Change definition to match declaration in
3409 * init.c (scm_boot_guile): Don't return the value of
3410 scm_boot_guile_1. This function doesn't return a value;
3411 scm_boot_guile_1 doesn't return a value (or return at all).
3413 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3416 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3417 compile. I have a feeling this function is a bad idea anyway ---
3418 one should always test for features, not systems.
3420 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3421 semicolons. Only pure luck kept this from being noticed earlier.
3423 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3425 * socket.c (scm_recvfrom): Added missing semicolon.
3427 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3429 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3430 the buffer and start and end positions for scsh networking
3433 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3435 * configure.in: Revert previous change to this file; the problem
3436 is due to transient automake weirdness.
3437 * configure: Rebuilt.
3439 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3440 PLUGIN/guile.libs. configure generates the latter from the former.
3441 * Makefile.in: Rebuilt.
3443 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3444 need this if we install scripts, like guile-snarf.
3445 * configure: Rebuilt.
3447 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3449 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3451 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3453 * socket.c (scm_addr_vector): fix faulty scm_listify.
3455 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3457 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3458 style block comment is no longer considered an error.
3460 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3462 * PLUGIN/guile.libs.in: New file.
3463 * PLUGIN/guile.libs: Removed from repository.
3464 * configure.in: Create PLUGIN/guile.libs from
3465 PLUGIN/guile.libs.in. This is for including additonal libraries
3466 needed for dynamic linking.
3467 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3468 instead of PLUGIN/guile.libs.
3470 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3472 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3474 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3475 occurrences of the given element from the list, not just the
3476 first. This is how the Emacs Lisp functions behave, how the
3477 analogous Common Lisp functions behave, and (I believe) how the
3478 older Maclisp functions worked. I realize that this change may
3479 break code, but it seemed better to break it before the Guile
3482 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3483 Their prototypes were already present in gc.h, but they weren't
3485 (scm_init_storage): Initialize scm_protects.
3486 * root.c (scm_protects): New element of scm_sys_protects.
3488 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3490 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3492 * libguile.h: Added #include "libguile/net_db.h".
3494 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3495 30 change. That file is only meant for communication between the
3496 configuration process and load.c. If code linked against libguile
3497 wants to get at the paths mentioned in libpath.h, it can call
3498 functions declared in load.h.
3500 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3502 * libguile.h: Removed #include "libguile/fdsocket.h"
3504 * net_db.c: Added #include <sys/socket.h>.
3506 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3508 * filesys.c (scm_input_waiting_p): use select in preference to
3509 FIONREAD, since the latter doesn't detect EOF.
3510 Throw error if neither select nor FIONREAD available.
3512 * socket.c (scm_connect): take a port, not a fd object.
3513 (scm_fill_sockaddr): throw an error if fam is not recognised.
3514 (scm_bind): use scm_fill_sockaddr.
3515 (scm_listen): take a port, not a fd object.
3516 (scm_accept): take and return a port. return #f in the car if
3517 address can't be got
3518 (scm_sock_fd_to_port): new procedure.
3519 (scm_socket): use scm_sock_fd_to_port.
3520 (scm_addr_vector): throw error if unrecognised address type.
3521 take an extra argument with the calling procedure name.
3522 (scm_getsockname): take a port. return #f if address can't be got.
3523 (scm_getpeername): take a port. return #f if address can't be got.
3524 (scm_recvfrom): take a port. return #f for address component if can't
3526 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3527 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3529 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3531 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3532 use separate data pointers, to allow them to be designed
3533 independently and reused.
3534 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3535 Renamed from catch_body, catch_handler, and uncaught_throw; made
3537 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3539 (scm_catch): Use the above.
3540 (scm_throw): Don't bother printing a message for an uncaught
3541 throw; we establish a default handler in init.
3542 * throw.h (scm_internal_catch): Prototype updated.
3543 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3545 (struct scm_body_thunk_data): New structure, used as data
3546 argument to scm_body_thunk.
3547 * init.c (struct main_func_closure): New structure, packaging up
3548 the data to pass to the user's main function.
3549 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3550 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3551 scm_internal_catch to establish a catch-all handler, using
3552 scm_handle_by_message. This replaces the special-case code in
3554 (invoke_main_func): Body function for scm_internal_catch; invoke
3555 the user's main function, using the main_func_closure pointer to
3556 decide what to pass it.
3557 * root.c (struct cwdr_body_data): Remove handler_proc member.
3558 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3559 (cwdr_handler): Removed.
3561 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3563 * socket.h (SCM_P): update bind prototype.
3564 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3565 include "feature.h".
3566 (scm_socket): return a port, not a file descriptor object.
3567 include "fports.h" and <unistd.h>
3568 (scm_bind): take a port, not a file descriptor object.
3569 take an extra argument for address args.
3571 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3572 INADDR_NONE, INADDR_LOOPBACK.
3574 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3576 * init.c: include net_db.h and not fdsocket.h.
3577 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3579 * Makefile.am: corresponding changes.
3580 * socket.h: renamed from fdsocket.h, fix names.
3581 * net_db.h: renamed from socket.h, fix names.
3582 * socket.c: renamed from fdsocket.c.
3583 remove _sys from procedure names.
3584 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3585 add "socket" to features list.
3586 * net_db.c: renamed from socket.c.
3587 remove _sys from procedure names.
3588 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3589 add "net-db" to features list.
3590 include "net_db.h". don't include <sys/socket.h> or
3593 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3595 * tags.h (scm_tags): Removed comma at end of last enumerator.
3597 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3599 Don't use GCC extensions to allocate space for debugging frames.
3600 (Here he goes again! Why do we put up with this?!)
3601 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3602 an scm_debug_info structure, not an in-line array of them. Add
3603 'info' member, to say how many vect elements we've used, for eval
3605 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3606 a new variable debug_info_end to mark the end of vect, instead of
3607 the address of the 'info' pointer itself.
3608 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3609 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3610 (SCM_APPLY): Explicitly allocate space for debug.vect.
3611 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3612 * stacks.c: Adjusted for new debug frame structure.
3613 (RELOC_INFO, RELOC_FRAME): New macros.
3614 (stack_depth, read_frames): Use them, and new scm_debug_frame
3615 element 'info', instead of magically knowing that eval frames have
3616 an info pointer sitting after vect.
3617 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3619 (scm_init_stacks): Formatting tweaks.
3621 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3623 Give GCC more control flow information, so it can be sure that
3624 variables aren't used uninitialized.
3625 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3626 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3627 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3628 scm_misc_error): Tell GCC that these functions never return.
3629 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3630 out the field type, call abort if SCM_ASSERT returns, to placate
3632 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3633 scm_wta ever returns. We can't handle this case anyway, and this
3634 gives the optimizer more information.
3635 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3636 scm_wta ever returns.
3638 In some cases, the code is fine, but GCC isn't smart enough to
3639 figure that out; this usually happens when one variable is only
3640 initialized and used when a particular condition holds true, and
3641 we know that condition will never change within a given invocation
3642 of the function. In this case, we simply initialize the variables
3643 to placate the compiler, hopefully to a value which will cause a
3644 crash if it is ever actually used.
3645 * print.c (scm_iprin1): Initialize mw_pos.
3646 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3647 * throw.c (scm_ithrow): Initialize dynpair.
3648 * unif.c (scm_uniform_vector_ref): Initialize cra.
3649 * struct.c (init_struct): Initialize prot.
3650 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3652 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3653 if EXPR contains no expressions.
3655 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3657 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3658 cause an infinite loop (???). So much for the algebraic
3659 equivalency of variable-sized arrays and alloca...
3661 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3663 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3664 a SCM boolean, not a C boolean.
3666 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3668 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3669 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3670 rules for raising scm_mtrigger. Previously, unfortunate but not
3671 unlikely circumstances could result in almost constant invokation
3672 of the gc. Now, this situations should be less likely, but they
3673 are not prevented completely.
3675 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3677 * numbers.c (scm_fuck): Procedure removed; looks like old test
3679 * numbers.h: Prototype removed.
3681 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3683 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3684 array to a pointer, to match my Nov 21 change in eval.c.
3686 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3688 * libguile.h: Added #include "libguile/backtrace.h", #include
3689 "libguile/stacks.h".
3691 * strings.c (scm_string scm_make_string scm_string_ref
3692 scm_string_set_x scm_string_equal_p scm_string_append):
3693 Bugfix according to scm patch from Aubrey Jaffer:
3694 Corrected long-standing
3695 (not (eqv? (integer->char 128)
3696 (string-ref (make-string 1 (integer->char 128)) 0)))
3697 bug found by John Kozak <jk@noontide.demon.co.uk>.
3699 * strports.c, strports.h: Make scm_eval_0str return the value of
3700 the last expression evaluated (previously, it returned void).
3702 * strports.c, strports.h: New function: scm_read_0str. Does what
3705 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3707 * simpos.c (scm_getenv): return #f if string can't be found in the
3708 environment instead of throwing an exception, for compatibility
3709 with numerous other systems.
3711 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3713 * Makefile.am (.c.x): Use guile-snarf.
3714 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3716 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3718 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3720 * backtrace.c (scm_display_error_message): Made non-static, and
3721 renamed from display_error_message.
3722 * backtrace.h (scm_display_error_message): Added extern decl.
3723 * throw.c (uncaught_throw): Use it to display the error message.
3725 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3727 * inet_aton.c: Use #if 0, not #ifdef 0.
3729 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3731 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3732 to convert the returned value.
3733 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3734 the offset argument.
3736 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3738 Add new interface to catch/throw, usable from C as well as
3740 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3741 (scm_internal_catch): New function, replaces...
3742 (scm_catch_apply): Deleted.
3743 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3744 mechanism which is a bit more code, but can be used nicely from C
3745 and implement the Scheme semantics as well.
3746 (scm_internal_catch): This is the replacement; it's named after
3747 the analogous function in Emacs.
3748 (scm_catch): Reimplemented in terms of the above.
3749 (struct catch_body_data, catch_body, catch_handler): New
3750 functions, used by scm_catch.
3751 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3752 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3753 support for new cwdr.
3755 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3758 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3760 * acconfig.h: Added DYNAMIC_LINKING symbol.
3761 * configure.in: Add option and checks for dynamic linking.
3762 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3763 dynl.h: New files for dynamic linking support.
3764 * Makefile.am (libguile_a_SOURCES):
3766 (modinclude_HEADERS): Added "dynl.h".
3767 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3769 * init.c (scm_boot_guile_1): Call
3770 scm_init_dynamic_linking to initialize dynamic linking support.
3772 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3774 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3775 (as we Schemers say). It needs to be global, so that I can tweak
3776 it for the proper operation of unexec.
3777 (scm_boot_guile_1_live): New variable, see above.
3779 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3781 * guile-snarf.sh: Removed.
3782 * PLUGIN/guile.libs: Added dependency for -lm.
3783 * acinclude.m4: Renamed from aclocal.m4.
3784 * PLUGIN/greet: Removed.
3785 * Makefile.am, aclocal.m4: New files.
3786 * configure.in: Updated for Automake.
3788 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3790 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3791 and not top_level_lookup_thunk_var.
3793 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3795 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3797 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3799 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3800 Scheme function, instead of syntax. Single argument is now a
3803 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3805 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3806 scm_ra_divide): Properly terminate statements passed as arguments
3807 to IVDEP macros. (Thanks to Bernard Urban.)
3809 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
3810 with non-constant sizes. (Thanks to Bernard Urban.)
3812 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3814 It's an "eval closure", not an "eval thunk." A thunk is a
3815 function of no arguments.
3816 * root.h (struct scm_root_state): Renamed
3817 top_level_lookup_closure_var from top_level_lookup_thunk_var.
3818 (scm_top_level_lookup_closure_var): Renamed from
3819 scm_top_level_lookup_thunk_var.
3820 * root.c (mark_root): Uses changed.
3821 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
3822 * init.c (scm_start_stack): Uses changed.
3823 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
3824 Change scheme-visible name to *top-level-lookup-closure* from
3825 *top-level-lookup-thunk*.
3827 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
3829 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
3830 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
3832 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
3834 * gc.c (struct scm_heap_seg_data): Doc fixes.
3836 * gc.c (scm_gc_sweep): Empty all segments' freelists before
3837 sweeping. Then, prepend each segment's free cells to its
3838 freelist, rather than wiping out the old value. (Thanks to Marius
3841 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
3842 scm_check_freelist, scm_debug_newcell): New functions and
3843 variables, for debugging freelist problems.
3844 * pairs.h (SCM_NEWCELL): New debugging version added.
3845 * gc.h (scm_debug_newcell): Added extern declaration, used by
3846 debugging version of SCM_NEWCELL.
3848 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3850 On some systems <libc.h> conflicts with <unistd.h>, and should not
3851 be #included at all.
3852 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
3853 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
3854 * configure.in: Call it.
3855 * posix.c, filesys.c: Use its results to decide whether or not to
3857 * configure, scmconfig.h.in: Rebuilt with autoconf and
3860 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3862 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
3863 pointer to the stdio stream before calling scm_setbuf0, so the
3864 latter will be able to retrieve it. I'm surprised this didn't
3865 segfault earlier. (Thanks to Christopher Lee.)
3867 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3869 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
3872 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3874 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
3875 number of stack narrowing specifier pairs. The first specifier in
3876 a pair controls inner border, the second the outer border. A
3877 number means cut that number of frames, a procedure object means
3878 cut until that object is found in operator position in a frame.
3880 * root.c (cwdr): Bugfix.
3882 * read.c: Recording of positions disabled by default.
3884 * procs.c (scm_closure_p): New function.
3886 * posix.c (scm_tmpnam): New function.
3888 * load.c: Added #include "throw.h".
3889 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
3892 * load.c, load.h (scm_read_and_eval_x): New function.
3894 * eval.c: Renamed debug option "deval" to "debug".
3896 (scm_eval_x): `eval!' is no longer accessible from the scheme
3897 level. Motivation: We can't allow operations which introduce
3898 glocs into the scheme level. Guile's type system can't handle
3899 these as data. Use `eval' or `read-and-eval!' as replacement.
3901 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
3902 SCM_CONSP since this is a macro!; Set vframe.prev to
3903 scm_last_debug_frame instead of 0. In this way we can look
3904 "above" the virtual start stack frame if we wish.
3905 (scm_debug_hang): New function: Useful for debugging Guile in
3906 certain tricky situations. Will probably be removed later...
3908 * debug.h: Changed semantics of debug option "backtrace". This
3909 option now only indicates whether we want automatic backtrace at
3912 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3914 * ports.c: #include "filesys.h"
3915 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
3917 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
3918 Motivation: This is system specific code which is related to file
3919 I/O. It also may use select. Added code by Gary Houston to
3920 detect presence of character in stdio buffers.
3922 * libguile.h: #include "libguile/libpath.h"
3924 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
3925 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
3926 SCM_SITE_DIR; Install libpath.h among the other include files.
3928 * load.c, load.h (scm_sys_package_data_dir): New function.
3930 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3932 * stacks.h: Bugfix: Don't use tail-array length field as stack
3933 length field! This screwed GC.
3935 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3937 * _scm.h: Added #ifndef around definition of macros min and max.
3939 * __scm.h: Added hooks for threads to plugin to in ints protection
3940 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
3941 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
3942 the main code in these macros duplicated and spread over multiple
3943 files. Renamed SCM_THREADS_SWITCHING_CODE ->
3944 SCM_THREAD_SWITCHING_CODE.
3946 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
3948 * snarf.h: New file.
3949 * guile-snarf.sh: New file.
3950 * Makefile.in (inner_h_files): Added snarf.h
3951 (ancillary, install, uninstall, distclean): Added actions for
3953 (.c.x): Use guile-snarf.
3954 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
3955 (gen_c_files): Note that these depend on guile-snarf.
3956 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
3957 now in "snarf.h". Added #include "snarf.h" to get them.
3958 * libguile.h: Added #include "snarf.h".
3959 (Patches applied and tweaked by Jim Blandy.)
3961 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3963 * socket.c: Use K&R style declaration for 'close'; the GNU coding
3964 standards suggest against providing prototypes for system
3965 functions. Thanks to Greg Troxel.
3967 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3969 * strports.c (scm_eval_0str): New function.
3970 #include "read.h", to get prototype for scm_read.
3971 * Makefile.in (strports.o): Update dependencies.
3972 * strports.h: New prototype.
3974 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
3975 scheme name from "int?" to "integer?". It seems to do the job.
3976 * numbers.h: Rename prototype too.
3977 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
3980 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
3981 scm_num_eq_p): Rename these according to R4RS conventions: call
3982 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
3983 to making libguile R4RS compliant without ice-9...
3985 * load.c (scm_sys_search_load_path): Search for files under all
3986 extensions listed in the %load-extensions variable. If FILENAME
3987 is absolute, return it unchanged, without searching the load path.
3988 (scm_loc_load_extensions): New variable, pointing to
3989 %load-extensions' value cell.
3990 (scm_init_load): Initialize it, and the value it points to.
3991 (scm_primitive_load_path): Improve error reporting.
3993 * load.c (scm_loc_load_hook): New variable, pointing to value cell
3994 of new Scheme variable %load-hook.
3995 (scm_primitive_load): Apply %load-hook to filename.
3997 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
3999 * configure.in: add tests for figuring out whether buffered data
4000 is available in a FILE structure, which is needed by char-ready.
4002 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
4005 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
4006 exceptions using misc_error instead of syserror. It seems a bit
4007 odd to throw an exception if a string can't be found in the
4008 environment, but it's consistent with open-file, stat etc.
4009 (simpos.h): remove sys_ from getenv.
4011 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
4012 occurs, throw an error instead of returning errno. Return value
4014 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
4016 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
4018 * filesys.c (scm_stat2scm): derive file type and permissions from
4019 the stat mode and append them to the returned vector.
4020 There isn't much overhead in doing this and it avoids the need to
4021 work with S_IRUSR et al. in Scheme.
4022 Define symbols scm_sym_regular etc.
4023 (scm_init_filesys): don't intern S_IRUSR etc.
4025 * load.c: change s_try_load and s_try_load_path to s_primitive_load
4026 and s_primitive_load_path.
4028 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
4030 * error.h: don't declare error symbols. prototype for scm_misc_error.
4032 * stackchk.c (scm_stack_overflow_key): defined here instead of in
4035 * error.c: use SCM_SYMBOL to set up error keys.
4036 scm_misc_error: new procedure.
4038 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
4040 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
4041 between `#!' and `!#' is ignored.
4042 (skip_scsh_block_comment): New function.
4044 * feature.c (scm_set_program_arguments): New argument, FIRST.
4045 * feature.h: Update prototype.
4046 * init.c (scm_boot_guile_1): Pass new argument to
4047 scm_set_program_arguments.
4049 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
4051 * init.c (scm_start_stack): Don't initialize scm_progargs here.
4052 (scm_boot_guile): Call scm_set_program_arguments here, later than
4053 the old initialization.
4055 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
4056 initialization procedure.
4057 - Delete in, out, err arguments; there are other perfectly good
4058 ways to override these when desired.
4059 - Delete result argument; this function shouldn't ever return.
4060 - Rename init_func argument to main_func, for less confusion.
4061 - Delete boot_cmd argument; main_func is more general.
4062 -Add 'closure' argument, to help people pass data to main_func
4063 without resorting to global variables.
4064 - Abort if reentered; don't bother returning an error code.
4065 - Call scm_init_standard_ports to set up the default/current
4066 standard ports; no need to pass them to scm_start_stack.
4067 - Remove code to evaluate the boot_cmd, and start the repl; let
4068 the user do something like that in main_func if they want.
4069 - Remove code to package up a return value; main_func can do any
4071 - Call exit (0), instead of returning.
4072 (scm_start_stack): Don't initialize the I/O ports here; that's
4073 weird. Delete in, out, err arguments. Move guts to
4074 scm_init_standard_ports, scm_stdio_to_port.
4075 (scm_init_standard_ports): New function, to set up current and
4076 default standard ports.
4077 (scm_start_stack, scm_restart_stack): Make these static.
4078 * init.h (scm_boot_guile): Adjust declaration.
4079 (scm_start_stack, scm_restart_stack): Remove externally
4080 visible declarations for these.
4081 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
4083 * fports.c (scm_stdio_to_port): New function. Its guts used to be
4084 written out several times in scm_start_stack.
4085 * fports.h: New declaration for the above.
4087 * feature.c (scm_set_program_arguments): New function.
4088 * feature.h: New declaration for the above.
4090 * ports.c: Formatting tweak.
4092 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
4094 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
4095 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
4096 for obtaining the address of a car or cdr field. Motivation:
4097 &SCM_CXR make assumptions about the internal structure of the
4100 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
4101 Motivation: see SCM_CXRLOC.
4103 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
4104 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
4105 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
4106 Motivation: Safer use. Some other macros are defined in terms of
4107 these operations. If these are defined using the SCM_SETCXR
4108 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
4109 to inefficiency and an <e1> with side-effects could potentially
4110 break. Also, these particular operations are heavily utilized in
4111 the garbage collector. In unoptimized code there will be a
4114 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
4115 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
4116 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
4117 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
4118 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
4119 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
4120 vports.c: Cleaned up use of pairs: Don't make any special
4121 assumptions about the internal structure of selectors and
4122 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
4123 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
4124 (Among other things, this change makes it easier to build Guile
4125 with certain compilers which have problems with casted lvalues.)
4127 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4129 * stacks.c: Improve selection of relevant stack frames when making
4130 a stack object. Introduce one level of indirection in the stack
4131 object to make it possible to "narrow" to a certain region of the
4132 stack. This facilitates making use of more clever algorithms (not
4133 implemented) for selecting relevant frames and gives a cleaner
4134 design since selection of frames can be done independently of
4135 extraction of frames from the real stack.
4136 (scm_stack_id): Also take #t as argument which means look at
4139 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
4140 Turn n_tail into an integer directly representing current number
4141 of frames in stack. Add field tail.
4143 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
4145 * debug.c (scm_make_memoized): Made it available at scheme level.
4146 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
4147 SCM_NIMP before applying heavier predicates in argument checking.
4148 (scm_local_eval): Also take memoized object as argument.
4150 * backtrace.c (scm_display_error): Just a safety measure: Stacks
4151 aren't created with zero length, but should such a strange
4152 creature suddenly turn up...
4154 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
4156 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
4157 `del', for the sake of C++ compilers. (Patch applied by JimB.)
4159 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
4161 * variable.c (scm_make_variable): Make the name hint optional, as
4163 (anonymous_variable_sym): Renamed from variable_sym. All uses
4166 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4167 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4168 of scm_primitive_load_path was also changed to
4169 "primitive-load-path", from "%try-load-path". Callers changed.
4170 We'd like to respect the convention that a function named
4171 "try-mumble" should behave just like the function called "mumble",
4172 but return #f instead of signalling some error.
4173 * load.h: Rename prototypes.
4175 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4177 * print.c (make_print_state, grow_print_state), print.h: Modified
4178 the print state representation: Don't use a tail array for
4179 recording of circular references. Resizing of the print state
4180 structure invalidates the print state pointer. To avoid passing
4181 around an indirect print state reference to all printing
4182 functions, we instead let the print state reference a resizable
4185 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4187 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4188 Don't crash when passed an improper list terminated by a
4189 non-immediate value.
4191 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4193 Allocate data for structures on an eight-byte boundary, as
4194 required by the tagging system.
4195 * struct.c (alloc_struct): New function.
4196 (scm_make_struct, scm_make_vtable_vtable): Call it.
4197 * struct.h (scm_struct_n_extra_words): Bump to 3.
4198 (scm_struct_i_ptr): New "field".
4199 * gc.c (scm_gc_sweep): When we need to free the data, use the
4200 information stored by alloc_struct to find the beginning of the
4201 block allocated to the structure, so we can free it.
4203 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4205 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4208 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4209 (scm_debug_info): New member: id.
4211 * stacks.c: Stacks are now represented as structs; Stacks have an
4212 id given to them by `start-stack'.
4213 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4215 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4216 Changed stack representation.
4218 * debug.c (scm_procedure_name): Try procedure property `name' for
4219 compiled closures aswell.
4221 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4223 * eval.c: scm_i_name moved to gsubr.c
4224 (scm_m_define): Record names of all kinds of procedure
4225 objects. (Earlier, only closures were recorded.)
4227 * procprop.h: Added declaration of scm_i_name.
4229 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4230 (scm_make_gsubr): Record names of compiled closures.
4232 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4234 * debug.c, debug.h: Removed obsolete code.
4236 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4237 stacks.c: Renamed regs --> scm_contregs.
4239 * print.c (scm_free_print_state): Cleanup print state before
4240 returning it to pool. It is better to do it here than in
4241 scm_prin1 since scm_prin1 is called often.
4243 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4244 s_set_source_property_x): Check that first argument is a pair or a
4247 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4248 scm_i_line, scm_i_column and scm_i_breakpoint global.
4250 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4251 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4254 * debug.h: Added debug object smob declaration and macro
4257 * configure.in: Build with backtrace.o and stacks.o if debug
4260 * Makefile.in: Added entries for new files: backtrace.c,
4261 backtrace.h, stacks.c and stacks.h.
4263 * symbols.c (scm_sym2ovcell): Fixed documentation.
4265 * _scm.h (min, max): Added.
4267 * async.c: Moved `min' macro to _scm.h.
4269 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4270 SCM_BACKTRACE_INDENT.
4272 * eval.c: Added new debug options `maxdepth' and `indent'.
4274 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4276 * print.h: Added selector SCM_PRINT_STATE.
4278 * print.c: New functions: scm_make_print_state,
4279 scm_free_print_state.
4281 * print.h: Added declarations for scm_make_print_state,
4282 scm_free_print_state.
4284 * debug.c (scm_m_start_stack): New acro.
4286 * debug.h: Small cleanup.
4288 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4291 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

4316 More prototype-related changes from Marius Vollmer:
4317 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4318 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4319 * ports.h (ptobfuns): Added prototypes. This means some casting in
4321 * fports.c: Added casts for initializations, since the functions
4322 are defined to take FILE * as their stream argument, not SCM.
4323 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4324 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4325 to `char *str_data' to conform to prototype.
4327 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4329 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4331 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4333 * stime.c, stime.h: use SCM_P method.
4335 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4337 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4338 be given at least two arguments. Insist that lst's last element
4339 be a list, but don't make any requirements of its predecessors.
4341 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4343 * eval.c (scm_nconc2last): Revert last change; there seems to be
4344 other stuff going on here.
4346 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4348 * eval.c (scm_nconc2last): Make sure that each element of lst
4349 (which is a list of argument lists, except for the tail) is a
4350 proper list, i.e., finite and terminated by '().
4352 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4354 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4357 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4358 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4361 * vectors.c (scm_make_vector): Fill vectors with the undefined
4362 value, to help make Guile Scheme code more portable to other
4365 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4366 * symbols.h, tags.h: Doc fixes.
4368 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4370 * async.c (scm_take_signal): Doc fixes.
4372 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4374 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4375 want to subtract it from the modulus; we just want to leave it
4378 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4380 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4383 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4385 * throw.c (scm_catch_apply): Finished implementation of
4388 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4390 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4392 (scm_init_filesys): set "i/o-extensions" feature.
4395 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4397 * Makefile.in (root.o): Correct dependencies.
4399 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4401 * Makefile.in: Added dependency entry for root.o.
4403 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4404 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4406 * init.c (scm_start_stack): Set initial root continuation number
4409 * procs.c: New function: scm_thunk_p.
4411 * procs.h: Added declarations of scm_thunk_p.
4413 * root.c: Renamed `call-with-new-root' -->
4414 `call-with-dynamic-root'.
4415 (cwdr): Removed allocation of new root state. This should be done
4416 separately by use of scm_make_root.
4417 (scm_apply_with_dynamic_root): New function: Does what it
4418 sounds like. Needed when spawning threads.
4420 * root.h: Added member last_debug_frame to root state.
4421 Added #include "libguile/debug.h"
4423 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4424 arguments. The motivation is that code in root.c needs catch
4425 functionality, and we want to avoid code duplication.
4426 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4427 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4428 handlers that run without popping the stack into the dynwind
4431 * throw.h: Added prototypes for scm_catch_apply and
4434 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4436 * root.h (scm_root, scm_set_root): Decouple thread support details
4437 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4438 SCM_SET_THREAD_LOCAL_DATA.
4440 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4441 and tortoise scanning loop.
4443 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4445 * Makefile.in: Rebuild dependencies.
4447 * libguile.h: #include "libguile/print.h" before "smob.h", since
4448 the latter uses the print_state structure.
4450 * throw.c (scm_ithrow): Use the correct variable when checking to
4451 see if a given element of scm_dynwinds is a valid catch.
4453 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4454 structure, abort; don't just silently ignore the garbage.
4456 * _scm.h: #include "print.h" here, since it seems to be used just
4458 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4459 strports.c, unif.h: Don't #include "print.h".
4461 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4463 * feature.h (scm_loc_features): Removed external declaration.
4464 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4466 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4468 * feature.c (scm_init_feature): Added threads feature (needs to be
4469 initialized here, since features doesn't exist when
4470 scm_init_threads is called).
4472 * libguile.h: Added #include "libguile/../threads/threads.h".
4473 (This is a kludge to get thread support working. This should be
4476 * configure.in, acconfig.h: Added flags for thread support.
4478 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4481 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4482 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4485 * _scm.h: Added conditional #include "threads.h"
4487 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4488 SCM_THREADS_SWITCHING_CODE.
4490 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4491 allocate the basic dynamic root object.
4492 (scm_boot_guile): Added call to scm_init_root.
4494 * root.c, root.h: Added root smob.
4495 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4496 functions: Implements dynamic roots mostly according to spec in
4497 SCM manual. Main difference is that the second argument is a
4498 throw handler rather than an error "thunk".
4500 * root.h: Added declaration of scm_init_root.
4502 * root.c: Added #include "genio.h", #include "smob.h", #include
4503 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4505 (scm_init_root): Added #include "root.x".
4507 * throw.c: Added #include "stackchk.h"
4508 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4509 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4510 can be used in scm_call_with_new_root; Added reenabling of stack
4511 checking when catching a throw.
4513 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4515 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4517 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4518 element is not found, as per R4RS.
4520 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4522 * list.c: Doc fixes throughout.
4524 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4526 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4527 declare the char * to be const. Avoids a warning in rgx.c.
4529 * ports.h: spelling fix.
4531 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4534 * load.c (scm_sys_try_load_path): throw an error if file not found
4535 (like it says it in NEWS).
4537 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4539 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4540 PROPS slot to '(), not #f; it's an empty alist.
4542 * throw.h, throw.c: Use SCM_P instead of #if hair.
4544 Remove special support for uncaught throws; see throw.c for
4546 * throw.c (uncaught_throw): New function.
4547 (scm_ithrow): Call uncaught_throw if we don't find a throw
4548 target; don't mess with scm_bad_throw_vcell.
4549 (scm_bad_throw_vcell): Variable deleted.
4550 (scm_init_throw): Don't initialize it.
4552 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4555 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4557 * numbers.c (scm_istr2int): If the number is short (as most
4558 numbers are), just call scm_small_istr2int to deal with it.
4559 (scm_small_istr2int): New function, created by un-#ifdefing the
4560 non-bignum version of scm_istr2int and renaming it.
4562 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4564 * load.c (scm_sys_try_load): don't check whether value returned
4565 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4566 Change the Scheme name from %try-load to primitive-load.
4568 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4569 Can avoid passing a message, allowing it to be derived in the
4570 error handler (e.g., if we want to throw to the key both from
4573 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4575 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4576 references now have a new appearance which is more compact and
4577 also gives a clue about what the target of the reference is.
4578 By setting parameters in the print state, more fancy printing can
4579 be achieved. This is used by the (not yet commited) backtrace
4582 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4584 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4587 * print.c: Added #include "struct.h". Removed function
4590 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4591 scm_iprin1. Removed prototype for scm_prlist.
4593 * arbiters.c (prinarb),
4594 async.c (print_async),
4595 debug.c (prindebugobj, prinmemoized),
4596 eval.c (prinprom, prinmacro),
4597 filesys.c (scm_fd_print, scm_dir_print),
4599 mallocs.c (prinmalloc),
4600 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4601 smob.h (scm_smobfuns),
4602 srcprop.c (prinsrcprops),
4604 unif.c, unif.h (scm_raprin1, rapr1),
4605 variable.c (prin_var): Changed argument `int writing' to
4606 `scm_print_state *pstate'.
4608 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4609 that it will be called before scm_init_print.
4611 * print.c (scm_prin1): Print states are now allocated when calling
4612 scm_prin1 and then passed around to all printing functions as an
4613 argument. A cache `print_state_pool' enables reuse of print
4615 (scm_make_print_state): New function.
4616 (scm_iprin1): Adaption to print states.
4617 (scm_iprlist): An initial "hare and tortoise" scan brings down
4618 time complexity to O (depth * N). (Better time complexity will be
4619 achieved when the printing code is completely rewritten.)
4621 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4623 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4624 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4625 it gets done whether or not the cache variable has a value.
4627 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4629 Distinguish #f and ().
4630 * __scm.h: #undef SICP.
4631 * pairs.h (SCM_EOL): Delete this definition, equating it with
4633 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4634 the value it used to have. Doc fixes, too.
4636 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4638 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4639 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4640 Lord's implementation of structs, allowing for tail arrays as
4641 described in the manual. Also fixed some bugs. (Both the interface
4642 and the implementation should be improved.)
4644 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4646 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4647 People who whish to see the source can do `(print-enable 'source)'.
4648 Removed #ifdef DEBUG_EXTENSIONS.
4650 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4652 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4653 integer (assuming for now accepting an integer is a good thing).
4655 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4656 %S will be used instead for write'ing arguments.
4658 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4659 asserts. fix a few other asserts.
4660 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4661 scm_uniform_vector_ref, scm_array_set_x,
4662 scm_dimensions_to_unform_array): change args in
4663 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4664 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4665 scm_substring_fill_x): likewise.
4666 gsubr.c (scm_gsubr_apply): likewise.
4667 eval.c (SCM_APPLY): likewise.
4669 * eval.c (4 places): replace scm_everr with lgh_error or
4672 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4673 scm_memory_error): new procedures.
4674 scm_everr: deleted. can use scm_wta, dropping first two args.
4675 scm_error: convert NULL subr to SCM_BOOL_F.
4677 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4680 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4683 * error.c, error.h: new error keys: scm_arg_type_key,
4684 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4686 scm_wta: reimplement using lgh_error instead of scm_everr.
4688 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4690 * gdbint.c: scm_lread now has one more argument.
4692 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4693 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4694 loading source from non-file ports, which, e. g., happens when
4695 using the Emacs interface).
4697 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4700 * read.c: Added code for recording of positions of source code
4701 expressions; New functions: recsexpr, scm_lreadrecparen;
4702 _scm_make_srcprops --> scm_make_srcprops
4703 (scm_flush_ws): Removed updating of positions counters. This work
4704 is already done by scm_gen_getc
4706 * read.h: Added prototype for scm_lreadrecparen
4708 * print.c: Added #include "alist.h"
4710 * eval.c: Added #include "hash.h"
4712 * eq.c: Added #include "ramap.h"
4714 * options.c: Documentation fixes.
4716 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4717 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4718 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4719 --> scm_make_srcprops
4721 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4722 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4723 function calls in the definition of the whash access macros.
4725 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4727 * init.c (scm_boot_guile): Add level of indirection to
4728 scm_boot_guile_1() to ensure that stack base pointer is properly
4729 initialized. There was no guarantee that variable i was the
4730 highest/lowest variable on stack (i.e. the call frame of
4731 scm_boot_guile was not completely protected from gc).
4733 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4735 * ports.h (scm_port_table): put back file_name, it will be used to
4736 support debugging. Undo related changes in fports.c, ioext.c,
4739 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4741 * ports.h (scm_port_table): remove file_name member for now, it seems
4743 * fports.c (scm_open_file): don't set file_name in PTAB.
4744 (prinfport): don't use file_name in PTAB.
4745 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4746 * ports.c (scm_add_to_port_table): don't intialize file_name.
4747 (scm_port_file_name): remove for now.
4748 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4750 * fports.h (scm_mkfile): prototype deleted.
4751 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4753 * debug.c, unif.c: use scm_out_of_range instead of
4754 wta for range errors (ASSERT still needs work).
4756 * error.c, error.h (scm_out_of_range): new procedure.
4758 * error.c, error.h (scm_out_of_range_key): new key.
4760 * posix.c (scm_sync): #else was missing.
4762 * error.c, error.h: append _key to names scm_num_overflow and
4765 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4766 of consing an empty list.
4767 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4768 of macros, saves code and string space.
4769 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4770 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4771 lower case. Rename scm_syserror_m to scm_syserror_msg.
4772 error.h: prototypes for new procedures.
4774 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4776 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4778 * error.c, error.h: setup scm_num_overflow key.
4780 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4781 Remove definition of SCM_OVSCM_FLOW.
4783 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4785 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4786 explicit message and args.
4788 * error.c, error.h, __scm.h: change system_error_sym to
4791 * error.c (system_error_sym): remove leading %% from the Scheme name
4794 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4796 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4798 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4799 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4800 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4801 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4802 renamed. (These were introduced by unsupervised name
4805 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4807 * print.c: Added code for detection of circular references during
4808 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4809 a hook for printing of closures (accessible via print options).
4810 This leads to a split of calls to scm_iprin1 into two classes:
4811 elementary print operations (e. g. the code which prints a smob)
4812 still use scm_iprin1 while top level calls (like scm_display) use
4813 scm_prin1. scm_prin1 begins by clearing the data structure used
4814 to record reference information.
4816 * print.h: Added declarations of scm_prin1 and scm_prlist.
4818 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
4820 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
4822 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
4824 * error.c (err_head): scm_iprin1 --> scm_prin1
4826 * debug.c: Adjusted header comment.
4830 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4832 * strerror.c: Doc fix.
4834 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4836 * gdbint.c (gdb_read): Now possible to run during GC.
4837 (unmark_port, remark_port): New functions.
4839 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
4841 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
4842 of allocating a new string object. Also, increase size by
4843 the factor 2 instead of 1.5.
4845 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
4847 * __scm.h (SCM_P): Corrected to run under traditional C.
4849 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
4852 * async.c: Calls to scm_sysintern corrected.
4854 * async.h (scm_async_clock): Redundant declaration removed.
4856 * continuations.c (scm_dynthrow): Redundant declaration removed.
4858 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
4859 Definition typos corrected.
4861 * debug.h: Missing declarations of functions in debug.c added
4864 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
4865 Missing declarations to functions in eval.c added.
4867 * filesys.c: Possibly uninitialized variable rv.
4869 * gc.h (scm_object_addr, scm_unhash_name): Missing
4870 declarations of functions defined in gc.c added.
4872 * genio.c: Possible typos str_data -> wstr_data. ???
4874 * genio.c: Possibly unintended shadowing of local variable
4875 `int c' (gotos out of scope of inner `c'). ???
4877 * init.c: Uninitialized `SCM last' may be used.
4879 * ioext.h: (scm_sys_isatty_p): Typo.
4881 * list.h (scm_list_head): Missing prototype for function in
4884 * numbers.c (scm_two_doubles): Changed from extern to static
4885 (is used only within numbers.c).
4887 * numbers.h: Repeated declarations removed.
4889 * ports.h (scm_close_all_ports_except): Declaration for the
4890 function defined in ports.c added.
4892 * posix.h: Missing declarations added.
4894 * procs.h (scm_make_subr_opt): Missing declaration added.
4896 * socket.h (scm_sys_gethost): Missing declaration added.
4898 * socket.h: Redundant declarations removed (they are in fdsocket.h).
4900 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
4901 Missing declarations added.
4903 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
4905 * struct.c: Uninitialized variable `SCM answer' may be used.
4907 * unif.c (l2ra): Declaration prototype.
4909 * unif.c (scm_array_equal_p): Dummy definition removed (it is
4910 defined in ramap.c).
4912 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
4913 Redundant declarations removed (they are in ramap.h).
4915 * variable.h (scm_make_udvariable,
4916 scm_make_undefined_variable): Declaration corrected to
4917 correspond variable.c.
4919 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
4920 Missing declarations added.
4922 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
4924 * Makefile.in (distclean): Don't forget to delete fd.h.
4926 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4928 * fd.h.in, tags.h: Trivial cleanups.
4930 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
4931 marksweep.h just declared functions from gc.c.
4932 * gc.h, libguile.h: Don't #include "marksweep.h".
4933 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4934 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
4935 dependencies updated.
4937 * libguile.h: Don't #include "files.h"; it's been deleted.
4939 * files.c (scm_sys_delete_file): Moved to filesys.c.
4940 File is now empty; deleted.
4942 * filesys.c: scm_sys_delete_file is now here. Remove
4943 #if's; they seem to rely on remnants of an old portability
4944 regimen. If the problems come up again, solve them properly,
4945 using autoconf. Specifically: Don't test M_SYSV, and #define
4946 remove to be unlink if it's #defined; don't use remove just
4947 because HAVE_STDC_HEADERS is #defined.
4948 * filesys.h: Add declarations for scm_sys_delete_file.
4949 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4950 files.o, files.h, files.c, and files.x.
4951 * init.c: Don't #include "files.h", and don't call scm_init_files.
4953 Use SCM_P instead of PROTO; the latter intrudes on the user's
4955 * params.h: Deleted; definition of SCM_P moved to...
4956 * __scm.h: ... here, where it replaces PROTO macro.
4957 * libguile.h, smob.h: Don't #include "params.h".
4958 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
4959 smob.h: Fix prototypes accordingly.
4960 * Makefile.in: Update dependencies.
4961 (inner_h_files): Remove params.h.
4963 * gc.c: #include "gc.h"; every module should include its header,
4964 to let the compiler cross-check the declarations against the
4967 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
4968 simpos.h: #include "libguile/__scm.h".
4970 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
4972 * init.c: Don't forget to #include smob.h and init.h.
4973 * Makefile.in: Dependencies updated.
4975 * smob.h: Use PROTO instead of #if __STDC__.
4977 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
4979 * __scm.h: Doc fixes.
4981 * __scm.h, libguile.h: Use "quotes" in the #includes, not
4982 <angles>; this allows `make depends' to work properly.
4984 * libguile.h: #include smob.h and pairs.h before the others; they
4985 define typedefs used by other headers.
4987 C files should #include only the header files they need, not
4988 libguile.h (which #includes all the header files); the pointless
4989 recompilation was wasting my time.
4990 * Makefile.in (all .o dependency lists): Regenerated.
4991 * libguile.h: Don't try to get a definition for size_t here...
4992 * __scm.h: Do it here.
4993 * _scm.h: Since this is the internal libguile header, put things
4994 here that all (or a majority) of the libguile files will want.
4995 Don't #include <libguile.h> here; that generates dependencies on
4996 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
4997 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
4998 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

5095 * weaks.c: Get "weaks.h".
5097 * stackchk.h: #include "libguile/debug.h",
5099 * print.h, read.h: #include "options.h", since everyone who uses
5100 either of these files will need that.
5102 * smob.h: #include "ports.h", "genio.h", and "print.h", since
5103 anyone who uses this file will need them to define the smob
5104 printing functions. Also, get markers.h, since people will need
5105 to #define the mark functions.
5107 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
5108 * ports.h: ... to here.
5110 * ports.h (scm_port_table_size): Explicitly give type as 'int';
5111 don't rely on archaic C default type rules.
5113 * fports.h: #include "libguile/ports.h", since you need that in
5114 order to parse this.
5116 * genio.h: #include "libguile/print.h", because you need that to
5117 parse this; don't bother #including "ports.h", since print.h gets
5120 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
5122 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
5123 this; it's now a reference to an element of *scm_root.
5125 * debug.h: Don't #include "options.h"; the compiler won't be able
5126 to find that once the headers are installed; instead, #include
5127 "libguile/options.h".
5128 * gc.h: Same, with marksweep.h.
5129 * mbstrings.h: Same, with symbols.h.
5130 * scmhob.h: Same, with _scm.h.
5131 * smob.h: Same, with params.h.
5133 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
5134 C files; there's no need for this, and it forces recompilations
5137 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
5139 * error.c (scm_error): declare scm_error_callback.
5141 * error.h: prototype for scm_error_callback.
5143 * __scm.h: define lgh_error.
5144 (SCM_SYSERROR): redefine using lgh_error.
5146 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
5148 * error.c (scm_error): new procedure.
5150 * error.h: prototype for scm_error.
5152 * Makefile.in (install): install scmconfig.h from the current
5153 directory, not $(srcdir).
5155 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5157 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5158 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5159 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
5160 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,

5164 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5165 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5166 vports.h, weaks.h: #include "libguile/__scm.h", not
5167 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5168 dependencies are within libguile properly.
5170 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5172 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5173 when scmconfig.h doesn't exist.
5175 * load.c (scm_sys_try_load): Correct spelling.
5177 * feature.c (scm_loc_features): Make this static.
5179 * Makefile.in (libpath.h): Omit trailing slash from path. We
5180 shouldn't require it of users, so why put it here?
5182 Move code to initialize and search %load-path from ice-9 to C
5183 code, so we can use the load-path to find the ice-9 boot code;
5184 this makes it easier to run Guile without installing it. See
5185 corresponding changes in guile/Makefile.in.
5186 * feature.c: Move stuff concerned with the load path to load.c.
5187 (scm_compiled_library_path): Deleted.
5188 Don't #include libpath.h here.
5189 * feature.h: Don't mention scm_compiled_library_path.
5190 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5191 <sys/stat.h>, and <unistd.h> (if present).
5192 (R_OK): #define if the system hasn't deigned to.
5193 (scm_loc_load_path): New variable.
5194 (scm_init_load_path, scm_sys_search_load_path,
5195 scm_sys_try_load_path): New functions.
5196 (scm_init_load): Initialize scm_loc_load_path to point to the
5197 value cell of the Scheme %load-path variable.
5198 * load.h: Add declarations for scm_sys_search_load_path,
5199 scm_sys_try_load_path.
5200 * init.c: Call scm_init_load_path.
5201 * Makefile.in (feature.o, load.o): Dependencies updated.
5203 * load.c, load.h: Rewrite using PROTO macro.
5205 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5207 * gc.c (scm_cellp): New function: C predicate to determine if an
5208 SCM value can be regarded as a pointer to a cell on the heap.
5210 * gc.h: Added declaration of scm_cellp.
5212 * gdb_interface.h: New file: The GDB interface header from the GDB
5215 * gdbint.c: New file: GDB interface.
5217 * gdbint.h: New file: GDB interface.
5219 * libguile.h: Added #include <libguile/gdbint.h>.
5221 * init.c (scm_boot_guile): Added scm_init_gdbint.
5223 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5224 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5225 found if object files and source are kept separate).
5227 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5229 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5231 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5233 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5234 TK_SRC_DIR; they're not relevant any more.
5236 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5237 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5239 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5241 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5242 search path, so we can find the <libguile/MUMBLE.h> headers.
5244 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5246 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5247 implicit in the .c.o rule.
5248 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5251 Put the library path in a header file, instead of passing it on
5252 the command line in every compilation.
5253 * Makefile.in (libpath.h): New target.
5254 (feature.o): Depend on libpath.h.
5255 (clean): Delete libpath.h.
5256 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5257 * feature.c: ... #include "libpath.h" here.
5258 * .cvsignore: Ignore libpath.h.
5260 Don't install the unwashed masses of Guile header files in the
5261 main #include path; put most of them in a subdirectory called
5262 'libguile'. This avoids naming conflicts between Guile header
5263 files and system header files (of which there were a few).
5264 * Makefile.in (pkgincludedir): Deleted.
5265 (innerincludedir): New variable; this and $(includedir) are enough.
5266 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5267 (installed_h_files): Divide this up. Now this variable lists
5268 those header files which should go into $(includedir) (i.e. appear
5269 directly in the #include path), and ...
5270 (inner_h_files): ... this new variable says which files appear in
5271 a subdirectory, and are referred to as <libguile/mumble.h>.
5272 (h_files): List them both.
5273 (install): Create innerincludedir, not pkgincludedir. Put
5274 the installed_h_files and inner_h_files in their proper places.
5275 (uninstall): Corresponding changes.
5276 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5277 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,

5284 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5285 vports.h, weaks.h: Find __scm.h in its new location.
5286 * __scm.h: Find scmconfig.h and tags.h in their new locations
5287 (they're both "inner" files).
5289 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5291 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5293 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5295 * posix.c: Doc fixes.
5297 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5299 * socket.c: Don't include a prototype for inet_aton; just use a
5300 K&R style declaration, to avoid warnings but minimize the chance
5301 of conflicts with the system.
5303 On NextStep, <utime.h> doesn't define struct utime, unless we
5304 #define _POSIX_SOURCE before #including it.
5305 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5306 * acconfig.h: New comment text for above CPP symbol.
5307 * configure.in: Call it.
5308 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5310 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5312 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5313 testing for __EMX__.
5315 * posix.c: #include <libc.h>, if it exists.
5317 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5318 don't even know if the latter exists.
5320 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5321 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5322 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5324 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5326 (scm_init_posix): Use them when initializing the Scheme constants
5329 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5331 * Makefile.in (libdir, includedir, bindir): Use the
5332 autoconf-supplied values, instead of deriving them ourselves.
5333 (pkgincludedir, datadir, pkgdatadir): New variables.
5334 (install, uninstall): Put the header files in a special
5335 subdirectory, not in the main search path.
5337 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5338 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5340 * Makefile.in (IMPLPATH): Deleted; never used.
5342 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5343 on the Tcl/Tk source any more.
5344 (INCLUDE_CFLAGS): Remove references to the above.
5346 * Makefile.in (version.o): Corrected dependencies.
5348 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5350 * libguile.h: #include "version.h"
5352 * init.c (scm_boot_guile): Call scm_init_version.
5353 * gscm.c (gscm_run_scm): Call scm_init_version.
5355 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5356 GUILE_VERSION): AC_DEFINE these.
5357 (acconfig.h): #undef the above symbols.
5359 * Makefile.in (libobjs): Add version.o.
5360 (installed_h_files): Add version.h.
5361 (c_files): Add version.c.
5362 (gen_c_files): Add version.x.
5363 (version.o): New rule.
5364 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5365 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

5373 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5374 weaks.o): Add version.h to dependency lists.
5375 (markers.o): Remove duplicate rule.
5377 * version.h: New file.
5379 * version.c: New file.
5381 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5383 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5384 array; use it appropriately. Since GCC is quite happy to
5385 subscript functions, it never warned us about this; we should use
5386 -Wpointer-arith in the future. I guess we never tested
5389 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5391 * socket.c: Doc and copyright fixes.
5393 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5395 * debug.c: Fixed and improved gdb support.
5397 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5399 * socket.c: Added declaration of inet_aton to avoid compiler
5400 warning. (Hope this solution is correct.)
5402 * stime.c: Added declaration of ftime. (This is missing in
5405 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5407 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5409 * Makefile.in (c_files): add strerror.c.
5411 * strerror.c: new file from Emacs' sysdep.c.
5412 maybe configure should also check for sys_errlist.
5414 * configure.in (AC_REPLACE_FUNCS): add strerror.
5416 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5418 * debug.c (scm_init_debug): Added initialization for
5419 scm_evaluator_traps.
5421 * debug.h, debug.c: Various name changes.
5422 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5423 "debug-options-interface". See commentary in options.c.
5425 * options.h, options.c: Options now have documentation strings.
5426 Also added a long explanatory commentary.
5428 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5431 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5432 last_debug_info_frame is now updated in all cases.
5434 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5437 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5439 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5440 Added option STACK_CHECKING.
5442 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5444 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5446 * __scm.h: Removed symbols for debugging support.
5448 * acconfig.h: Added symbols for debugging support.
5450 * configure.in: Added user option for debugging support.
5451 --enable-debug will include the debugging code into libguile.a.
5453 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5454 scm_relocate_chunk_to_heap.
5456 * debug.c: New file: low-level debugging support. It also
5457 includes support for debugging with gdb. (The extensions to gdb
5458 are written by Per Bothner at Cygnus.)
5460 * debug.h: New file: low-level debugging support.
5462 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5463 argument pairs. Extensive modifications to the debugging
5464 evaluator. Added "SECTION:" commentaries to clarify what happens
5465 when, during double compilation. Renamed EVALIMP --> EVALIM.
5466 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5467 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5468 the beginning of the file. New procedure: scm_unmemocopy.
5469 Added some global state variables needed by the debugging
5470 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5471 check_entry, check_apply, check_exit, debug_options and
5472 evaluator_traps. New acro: undefine.
5474 * eval.h: Renamed EVAL --> XEVAL.
5476 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5477 --> scm_make_weak_key_hash_table.
5479 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5480 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5482 * libguile.h: Conditionally include debug.h
5484 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5485 scm_object_properties shouldn't return handle. `handle' now gets
5486 initialized in scm_set_object_properties_x. scm_object_properties
5487 doesn't any longer create an entry in scm_object_whash.
5489 * options.c: New file: handling of run time options.
5491 * options.h: New file: handling of run time options.
5493 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5495 * print.c: New procedure: scm_print_options
5497 * print.h: Defines for print options.
5499 * read.c: New procedure: scm_read_options
5501 * read.h: Defines for reader options.
5503 * root.h: Added scm_source_whash among scm_sys_protects.
5505 * srcprop.c: New file: source properties.
5507 * srcprop.h: New file: source properties.
5509 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5510 (Bug found by A. Green.)
5512 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5514 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5516 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5518 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5520 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5521 and should be called by the final client.
5523 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5525 * gc.h: Use the PROTO macro when declaring functions.
5526 * gc.c: Use the PROTO macro when declaring static functions.
5527 Remove the CPP hair around function definitions.
5529 * gc.c (scm_init_storage): Initialize scm_asyncs.
5531 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5532 preprocessor symbol; "__scm.h" is where it might get #defined.
5533 * __scm.h: Similar: #include <scmconfig.h> before testing
5536 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5538 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5540 * init.c (scm_boot_guile): Add init_func argument; call
5541 (*init_func) instead of calling scm_appinit; it's ucky to
5542 hard-code names for the user's procedures.
5543 * init.h (scm_boot_guile): Adjust declaration.
5545 * __scm.h (PROTO): New macro, for declaring functions with
5548 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5549 eliminate all the __STDC__ conditionals.
5550 (scm_boot_guile): Add declaration.
5551 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5552 Remove __STDC__ conditionals around function definitions; the
5553 declarations in init.h will provide the same information, more
5556 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5557 complain about it in the error message; the error message is
5558 adequate without that note, and there's nothing the user can do
5561 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5563 * Makefile.in (ancillary): Drop def.sed.
5565 * posix.c (scm_init_posix): Use numeric values, rather than
5566 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5567 F_OK. The symbols aren't available on some systems, and I'm
5568 pretty sure their values are fixed by common widespread practice.
5569 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5571 More functions unavailable on some systems.
5572 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5573 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5575 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5576 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5577 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5578 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5579 stub that signals an error as the #else.
5581 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5583 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5585 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5587 * unif.c: include ramap.h.
5589 * read.c (endif): case_insensative_p renamed case_insensitive_p.
5591 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
5593 * ports.c: include sys/ioctl.h.
5595 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5597 * configure.in: check for sys/ioctl.h.
5599 * ports.c: include <malloc.h> not "malloc.h".
5601 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5603 * fports.c: remove ttyname and tmpnam declarations.
5605 * posix.c: fewer ttyname declarations.
5607 * fports.c: include <string.h> not "string.h".
5609 * init.c, ioext.c: include string.h and unistd.h.
5611 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5613 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5614 genio.c, simpos.c, vports.c: include string.h.
5616 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5618 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5620 (scm_addr_buffer_size): change type from scm_sizet to int.
5621 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5622 from scm_sizet to int.
5624 * error.c: include unistd.h.
5626 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5629 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5631 * __scm.hd, def.sed: deleted.
5633 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5635 Changes for NeXT, suggested by Robert Brown.
5636 * configure.in: Call AC_TYPE_MODE_T.
5637 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5638 NeXT. Put header file list in alphabetical order.
5639 * configure, scmconfig.h.in: Regenerated.
5640 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5642 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5645 * acconfig.h: New file, providing documentation for the CPP
5646 symbols defined in configure.in
5647 * acconfig-1.5.h: Removed; superceded by the above.
5649 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5651 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5653 * fports.c (scm_open_file): don't return #f, throw error.
5655 * ioext.c (fileno): renamed from %fileno.
5656 (soft-fileno): deleted.
5658 * ports.c (scm_port_revealed): don't need to check for -1 from
5660 (scm_set_port_revealed_x): return unspecified, not #f.
5662 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5664 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5666 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5668 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
5670 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5672 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5673 This is necessary on Ultrix, and doesn't hurt portability.
5675 * Makefile.in (dist-dir): New target, implementing a new dist system.
5676 (installed_h_files): Put in alphabetical order.
5677 Remove duplicate entries for markers.h and unif.h.
5678 (c_files): Remove duplicate entries for markers.c.
5679 (ancillary): Renamed from anillery; all uses changed. Remove
5680 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5681 Remove all the ../doc/* files; doc/Makefile.in handles that.
5683 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5685 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5686 every if must have an else, or else the whole command has a
5687 non-zero exit code whenever the if's condition is false.
5689 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
5691 * posix.c: include string.h.
5693 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
5695 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
5698 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
5699 Remove leading % from scheme names.
5700 Do not return error values, call SCM_SYSERROR or similar.
5702 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
5704 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
5706 * struct.c (scm_init_struct): new file.
5708 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
5710 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
5711 (scm_list_head): added list-head for rapidly chopping argument
5712 lists off of longer lists (and similar).
5714 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
5716 * objprop.c (scm_object_property): assq the cdr of the whash
5717 handle for obj, not the handle itself.
5719 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
5721 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
5722 weak hash tables last of all marking to avoid an obscure gc bug.
5723 WARNING: circular lists stored in a weak hash table will hose us.
5725 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
5727 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
5728 new functions similar to scm_substring_move_left_x and
5729 scm_substring_move_right_x.
5731 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
5733 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
5736 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
5738 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
5740 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
5742 * strports.c (scm_strprint_obj): convenience function. C for
5743 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
5745 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
5746 removed to a separate library
5748 * init.c (scm_boot_guile): copied from guile-tcl.c.
5749 Initialization specific to tcl interpreters removed.
5751 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
5753 * ports.c (scm_ports_prehistory): size malloced here doesn't
5754 matter so long as it is non-0 (got rid of "* 4").
5756 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
5758 * gscm.h: gscm_mkarray eliminated (presumably was not being used
5759 since its definition was bogus).
5761 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
5763 * mallocs.[ch]: back again (for rx at least).
5765 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
5767 * ports.c: removed functions relating to the mapping between ports
5768 and descriptors. (That stuff is unix-specific and should be collected
5769 in a separate library).
5771 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
5772 (Tom Mckay@avanticorp.com)
5774 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
5776 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
5777 handled correctly (SCM_FREEP was applied to them) -- test for
5778 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
5779 being overwritten with #f. (brown@grettir.bibliotech.com)
5781 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
5783 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
5784 for a specific symbol or for all symbols.
5786 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>

5946 initialization to fix a race condition.
5948 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
