17 1998-09-30 Mark Galassi <rosalia@cygnus.com>
19 * gh.h: took out the definitions of vset and vref, since they are
20 replaced by the proper vector routines that correspond to the R4RS
23 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
25 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
26 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
27 third argument, a C expression that should result in a SCM value,
28 which is used to initialize the variable. Reimplemented
29 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
32 * version.h (scm_libguile_config_stamp): Add prototype.
33 (From Maciej Stachowiak.)
35 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
37 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
38 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
40 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
42 * print.c (scm_iprin1): Rather than having one i, and using it in
43 several places, declare a fresh i local to each block where it is
44 used, and give it a signedness appropriate to its use in each case.
47 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
50 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
51 signed/unsigned clashes.
53 * posix.h (scm_tmpnam): Added prototype.
55 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
56 scm_make_subclass_object): Add external prototypes.
58 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
59 comparison is okay here.
61 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
63 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
64 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
66 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
69 * load.c (swap_port): Make this function static.
71 * load.c (scm_search_path): Make max_path_len and max_ext_len
72 unsigned, since they're compared against string sizes.
74 * load.c (init_build_info): Make i unsigned.
76 * ioext.h (scm_read_line): Add prototype.
78 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
79 scm_hash_fn_remove_x): Make hash bucket index local variable k
80 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
81 accurately as possible.
83 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
84 comparisons, and range checking to make sure those casts are
87 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
88 signed/unsigned comparisons.
90 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
91 avoid signed/unsigned comparisons.
92 * smob.h (scm_numsmob): Change extern declaration to match.
94 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
95 avoid signed/unsigned comparisons.
96 * ports.h (scm_numptob): Change extern declaration to match.
97 (scm_current_load_port, scm_set_port_line_x,
98 scm_set_port_column_x): New prototypes.
100 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
101 test code, and it causes warnings.
103 * gh.h (gh_int2scmb, gh_uniform_vector_length,
104 gh_uniform_vector_ref): Added prototypes.
106 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
107 debugging support unconditionally. That's backtrace.c, stack.c,
108 debug.c, and srcprop.c.
109 (EXTRA_libguile_la_SOURCES): Omit those from here.
110 * Makefile.in: Regenerated.
112 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
114 * options.c (scm_options): Bugfix: Allow empty list of options!
116 * debug.c, debug.h (scm_single_step): Removed.
117 (scm_with_traps): New procedure. This procedure could easily be
118 written in Scheme but needs to be highly optimized.
120 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
122 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
123 Check SCM_TRAPS_P before trapping.
125 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
127 Changes to avoid signed/unsigned comparison warnings.
128 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
129 (scm_gc_sweep): Make n and j local to the blocks they're used in,
130 so they can have appropriate types for each application. Make i
131 signed. Use initializers in some spots. I'll probably pay for
133 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
134 (scm_must_realloc): Make nm unsigned.
135 (init_heap_seg): Make new_seg_index and n_new_objects signed.
136 (scm_init_storage): Use prototype-style definition, and make the
138 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
139 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
141 * filesys.c (scm_readlink): Make local vars rv and size ints, to
142 avoid signed/unsigned comparison warnings, and because the return
143 value of readlink may be -1. Don't bother casting the third
144 argument to readlink.
146 * filesys.c (scm_dirname, scm_basename): Move these to their own
147 page, at the end of the file.
148 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
150 * eval.h (scm_eval_options_interface): Add external prototype for this.
151 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
153 * eval.c (scm_lookupcar1): Make this static.
155 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
156 Make these prototype declarations, not K&R-style.
158 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
159 unsigned comparison warning.
161 * appinit.c: File removed. It had a single function in it, empty,
162 whose reason for existence is explained in no documentation or
163 comment. I think it's there as a default for some Tcl-style
164 initialization, but Tcl abandoned that approach a while ago.
165 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
166 (BUILT_SOURCES): Remove appinit.x.
167 * Makefile.in: Regenerated.
169 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
171 * Makefile.in: Regenerated using the last public version of
172 automake, not the hacked Cygnus version.
174 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
176 Remove Totoro kludge.
177 * Makefile.in, scmconfig.h.in: Regenerated.
178 * init.c, readline.c: Don't check if TOTORO is #defined.
180 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
182 * Makefile.am: Adjust for new thread configuration system.
183 (INCLUDES): Include the value of THREAD_CPPFLAGS.
184 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
186 (THREAD_LIBS): Definition deleted; automake will generate such
187 things automatically.
188 * Makefile.in: Regenerated.
190 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
192 Simplify smob and port marking; set the mark bit in the generic
193 marking code, and make marker routines only responsible for
194 turning up outgoing pointers.
195 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
196 before calling the marking function. Don't call the marking
197 function if it's zero.
198 * markers.c (scm_mark0): Just return #f. This function isn't
199 necessary at all now, but it's harmless to call it. We'll leave
200 it in so other folks' code doesn't croak at link time.
201 (scm_markcdr): Don't call SCM_SETGC8MARK.
202 * async.c (mark_async): Don't call SCM_SETGC8MARK.
203 * dynl.c (mark_dynl_obj): Same.
204 * root.c (mark_root): Same.
205 * srcprop.c (marksrcprops): Same.
206 * unif.c (markra): Same.
207 * variable.c (scm_markvar): Same.
208 * ports.c (scm_markstream): Same.
209 (void_port_ptob): Specify zero for our marking function.
210 * debug.c (debugobjsmob): Same.
211 * dynwind.c (guardsmob): Same.
212 * filesys.c (dir_smob): Same.
213 * fluids.c (fluid_smob): Same.
214 * fports.c (scm_fptob, scm_pipob): Same.
215 * mallocs.c (mallocsmob): Same.
216 * regex-posix.c (regex_t_smob): Same.
217 * smob.c (freecell, flob, bigob): Same.
218 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
219 * throw.c (jbsmob, lazy_catch_funs): Same.
221 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
223 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
224 scm_copy_tree on code in order not to let memoized code to leak
225 out. Thus, scm_copy_tree needs to copy vectors as well since
226 quasiquote can introduce evaluated code also inside vector
229 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
231 * eval.c (scm_copy_tree): Removed ability to copy vectors.
233 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
234 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
237 * unif.c: Say that ivect and uvect are of type signed and unsigned
238 long instead of int in commentary so that it correctly describes
241 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
243 * stime.c: Removed declaration of strptime. (It should be
244 declared by the system headers. If it turns out that some systems
245 don't, we'll handle that then.) (Thanks to Greg Troxel.)
247 * stime.h: Renamed TIMEH --> STIMEH
249 * backtrace.c (scm_display_error, scm_display_backtrace): In order
250 to increase portability, don't use structure assignment.
251 (Thanks to Nicolas Neuss.)
253 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
255 (finalize_fd_sets): Added empty statement after last case label.
256 (Thanks to Nicolas Neuss.)
258 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
261 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
263 * init.c, readline.c: OK, I won't have these readline.x bug
264 reports anymore. We've had them since April. The current reason
265 is a completely unintelligible failure of totoro.red-bean.com to
266 do the test for rl_getc_function in libreadline correctly. This
267 kludge overrides the test if we're on totoro so that the snapshot
268 generation process can work.
270 * readline.c: Define a strdup replacement if not existent on system.
272 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
274 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
275 This change makes scm_make_vector R5RS compatible. We cannot keep
276 the third argument since people want to be able to deduce the form
277 of the C function call only by looking at R5RS. (At the same time
278 we have removed some unnecessary complexity!)
280 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
281 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
282 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
283 argument in call to scm_make_vector.
285 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
287 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
288 This macro is useful in applications.
290 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
292 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
293 (scm_parse_path, scm_search_path): New Scheme level procedures.
295 * load.h (scm_internal_parse_path, scm_parse_path,
296 scm_search_path): Declared.
298 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
300 * filesys.c (dirname, basename): New procedures.
302 * init.c (scm_boot_guile_1): Removed condition around
305 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
306 new data type (guards) for representation of C level guards and
307 data on the wind chain.
308 (scm_internal_dynamic_wind): New function.
310 * dynwind.h: Declare scm_internal_dynamic_wind.
312 * root.h (scm_root_state): Added scm_cur_loadp.
314 * root.c (mark_root): Added comment about cur_loadp.
316 * load.c: #include "dynwind.h";
317 (scm_primitive_load): Use scm_inner_dynamic_wind to update
320 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
322 * ports.c (current-load-port): New procedure.
324 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
326 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
327 not a tty, return #f.
329 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
330 to Julian Satchell and Roland Kaufmann.)
332 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
333 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
335 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
337 * debug.h, debug.c (scm_start_stack): New function. Implements
338 the guts of old scm_m_start_stack.
340 * debug.c (scm_m_start_stack): Use scm_start_stack.
342 * init.c (scm_start_stack, scm_restart_stack): Renamed to
343 start_stack and restart_stack. (These have static scope.)
345 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
347 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
348 readline functions to come in release 2.3. (Thanks to Chet
350 (handle_errors): Use the above functions.
352 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
354 * readline.c: Improvements for readline support: Handle errors
355 better; Implement before-read-hook.
357 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
359 * init.c (scm_boot_guile_1), readline.c: Test for
360 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
361 assure that we have version >= 2.1.)
363 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
365 * readline.c (scm_add_history): Bugfix: Do strdup before giving
366 away the string to add_history.
367 (completion_function): Do completion for readline. (Thanks to
369 (scm_filename_completion_function): New procedure: Filename
371 (current_input_getc): New function. Use this one instead of
372 standard getc from readline.
374 * throw.c, throw.h (scm_handle_by_throw): New function: This
375 handler throws errors to next handler on the dynwind chain.
377 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
379 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
382 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
384 * procprop.c (scm_i_procedure_arity): New function. Returns arity
386 (scm_procedure_properties): Modified to return arity together with
388 (scm_procedure_property): Added the read-only property `arity'.
389 (scm_set_procedure_property_x): It is an error to set the `arity'
392 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
393 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
395 * procprop.h (scm_sym_arity): New symbol.
397 * objects.c (scm_set_object_procedure_x): New procedure: Use this
398 to set the dispatch procedure of an operator or entity object.
400 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
401 Made procedure slots read-only.
403 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
404 scm_tcs_cons_gloc case in zero args switch; Fixed args
405 construction for operators in scm_tcs_cons_gloc case in two args
408 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
410 * fluids.c: Removed use of assert.h (in order to avoid
413 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
415 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
417 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
418 change makes the evaluator safer at the cost of evaluation speed.
419 It handles the case when the user has added a non-immediate
420 improper end of the application form, e.g., `(+ 0 . x)'.
421 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
422 minimize the extra cost as much as possible. The new code is
423 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
424 problem with structs planted directly in the code (e.g. by a
425 macro). This no longer causes segmentation fault. (Thanks to
428 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
429 arg `proc' in order to be able to throw errors; New argument
432 * Removed extra #include "debug.h"
434 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
436 * scmsigs.c: Declare usleep as returning void on some systems.
437 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
440 * coop.c (usleep): Return void on some systems.
442 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
444 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
446 * coop.c: Changed return type of usleep to int.
448 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
449 isn't found in the OS.
451 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
452 isn't enabled. (Thought that I had made this change ages ago...)
454 * iselect.c: Declare bzero if not defined by OS.
456 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
458 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
459 condition. (Thanks to John Tobey.)
461 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
462 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
465 * __scm.h: Start the long-term project of moving to POSIX threads.
466 Phase 1: Classification of all critical sections.
467 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
468 for A sections. (See comments in __scm.h for details.)
470 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
471 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
473 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
475 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
476 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
477 (libpath.h, versiondat.h): Replaced dependency on Makefile with
478 dependencies on $(srcdir)/Makefile.in
479 $(top_builddir)/config.status in order to avoid circularity.
481 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
482 from argc if argc was 0 initially.
484 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
485 in generation of libpath.h.
487 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
489 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
490 libguile from 2 to 3.
492 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
494 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
496 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
498 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
499 scm_set_port_column_x, scm_port_filename,
500 scm_set_port_filename_x): Removed optional arguments. Added
501 proper argument checking.
503 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
504 stack size in machine words.
506 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
507 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
508 to Ole Myren Röhne.)
510 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
512 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
513 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
515 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
518 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
519 procedure apply: Copy argument lists before pushing them unto the
520 environment so that the environment won't get mutated due to
521 manipulation of procedure arguments. This should perhaps be
522 regarded as a temporary solution until someone finds a more
523 efficient one. (Thanks to Maciej Stachowiak.)
525 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
527 * script.c (scm_compile_shell_switches): Use "guile" as default
528 zero arg if argc is NULL.
530 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
532 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
533 is zero. (Thanks to Dirk Herrmann.)
535 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
537 * ports.c (scm_add_to_port_table): First line is now line 0
538 (was 1). (Interface changed according to suggestion by Per
541 * backtrace.c (display_header): Add 1 to line and column numbers
542 when presenting them to the user.
544 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
545 from debug.c --> eval.c
547 * eval.h, eval.c (scm_eval_options_interface): New options
549 (SCM_EVAL_STACK): New option: Size of newly created stacks,
550 i.e. stacks for new threads.
552 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
554 * eval.c (unsafe_setjmp): Removed with #if 0.
556 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
559 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
560 to avoid compiler warnings.
562 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
564 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
566 * throw.c (handler_message): Print message on current error port
567 instead of default error port. (Thanks to Maciej Stachowiak.)
569 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
571 * ports.c (scm_add_to_port_table): allocate in units of
572 struct scm_port_table *, not struct scm_port_table.
573 * posix.c (scm_close_pipe): remove the port from the port table
575 Thanks to Rob Engle for both fixes.
577 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
579 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
580 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
582 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
584 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
586 * backtrace.c (display_error_body, display_backtrace_body),
587 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
588 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
589 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
590 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
593 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
594 don't receive the jmpbuf arg anylonger.
595 (scm_catch): Don't accept a #f tag.
596 (scm_throw): Check that key is a symbol.
597 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
599 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
601 * async.c (async_pending): Removed declaration.
603 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
605 * dynwind.c (scm_wind_chain): New debug function.
607 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
608 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
609 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
610 extra layer of functions around the body and handler of a thread.
611 This extra layer makes sure that the handler is called in the
612 dynamic context of the surround (= empty dynwind list), but under
613 the *dynamic root* of the body. We can not use the dynamic root
614 of the surround since that root belongs to another thread => stack
615 is not handled correctly. It may seem ugly to use this extra
616 layer, but the extra cost in terms of execution time is really
617 negligible compared to the total amount of time required to create
618 a thread, and it would reduce maintainability to duplicate the
619 crucial and complicated steps performed by cwdr.
621 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
622 (SCM_ALLOW_INTS): Added thread switching code before interrupts
623 get re-enabled. The important effect of this is that interrupts
624 are blocked during thread switching so that thread data structures
625 don't risk getting messed up by an unfortunate signal.
626 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
627 seems to do more aggressive optimization which actually move
628 instructions around in these macros in a fatal way. Therefore:
629 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
630 just superstitious...)
631 (SCM_TICK): Maybe do a context switch and take care of asyncs.
632 This macro should be used instead of SCM_ASYNC_TICK since the
633 latter doesn't do context switches any more.
635 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
636 instead of SCM_ASYNC_TICK.
638 * coop.c, iselect.c: Since thread switches are now performed with
639 interrupts masked, we can't use the old mechanism of delivering
640 signals immediately when they arrive. Signals must instead be
641 delivered when the asyncs run *after* the end of the critical
642 section in scm_internal_select. But this also means after context
643 switch so that the signal will be delivered to a different thread.
644 To avoid this, I have changed the protocol of
645 coop_wait_for_runnable_thread and friends so that they are allowed
646 to return the original thread. So, if a signal arrives during
647 scm_internal_select, we won't any longer be forced do a context
648 switch, but can remain in the same thread and deliver the signal
651 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
652 scm_asyncs_pending and made it global.
654 * iselect.c: Small fixes.
656 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
657 coop_condition_variable_init, coop_condition_variable_wait,
658 coop_condition_variable_signal): Changed return type from `void'
659 to `int'. This is to adhere closer to the pthreads interface.
660 This, in turn, is part of an attempt to provide C versions of the
661 mutex and condition variable primitives which can be part of a
662 frontend to COOP or pthreads.
664 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
665 coop_condition_variable_destroy): New functions.
667 * coop-threads.c (scm_wait_condition_variable): Use
668 coop_condition_variable_wait_mutex.
670 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
671 Definitions moved to coop-defs.h.
673 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
674 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
675 scm_cond_destroy): New C interface to mutecis and cond vars.
677 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
679 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
681 * iselect.c: Now several threads can wait on the same file
682 descriptor. The behaviour is compatible with OS select: All
683 threads waiting for the fd return with the same status.
685 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
687 * coop-threads.c, threads.h (scm_spawn_thread): New function.
688 Can spawn a thread from application C code.
690 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
692 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
693 gh_doubles2scm): New functions.
695 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
697 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
698 commented-out version of gh_eval_str()
700 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
702 * socket.c (scm_bind): free soka after use.
704 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
706 * stime.c (tzvar): new variable.
707 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
708 avoid memory leaks when allocating.
710 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
712 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
715 * gc.c, tags.h: Doc fixes.
717 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
719 * eval.c (macro-eval!): Removed. This function was a design bug.
720 It allowed memoized code to leak out to the scheme level. Most
721 things that you could do with `macro-eval!' can be done with
724 1997-12-20 Tim Pierce <twp@skepsis.com>
726 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
727 scm_fgets now depends on ftell(3) to know how many bytes were
730 1997-12-15 Tim Pierce <twp@skepsis.com>
732 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
733 dealing with strings.
735 1997-12-13 Tim Pierce <twp@skepsis.com>
737 Make %read-line more suitable for implementing read-line efficiently.
738 * ioext.c (scm_read_line): Strip the terminating newline from a
739 string, and return a cons of the string and its terminator.
741 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
742 of the string that is read is stored in this memory location.
743 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
744 * genio.c, genio.h (scm_do_read_line): Update caller.
745 * ports.h (scm_ptobfuns): Update typedef.
746 * fports.c (scm_fptob, scm_pipob): Update struct.
748 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
750 * filesys.c (set_element): Return file descriptor.
751 (fill_select_type): Return the highest file descriptor.
752 (scm_select): Tell select about the highest file descriptor. On
753 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
754 Therefore the extra overhead for calculating the maximum fd seems
755 to be more than compensated. Is this correct? In any case,
756 scm_internal_select will be much faster with this info.
757 (scm_select, fill_select_type, set_element): Don't accept any kind
758 of object in the file descriptor list or vector.
760 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
762 * iselect.c (finalize_fd_sets): Bugfix.
764 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
766 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
767 when using scm_internal_select (since we might switch to another
770 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
772 * simpos.c (scm_system): always define: use sysmissing if not
773 available. Check for HAVE_SYSTEM instead of _Windows (does
774 Windows lack system or does it have an unusable one?).
775 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
776 Let the argument be optional: if not supplied, call system(NULL).
778 * ports.c (scm_close_port): relax the type check from OPPORTP to
779 PORTP; closing a closed port is allowed.
781 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
783 * fports.c (scm_fgets): Return if the last char in a chunk is
784 newline. When fgets returns a string whose length is `size-1', it
785 is ambiguous whether a whole line was retrieved, so we must check
786 explicitly whether a line terminator is present.
788 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
790 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
791 before taking the CDR. (Thanks to Harald Meland.)
793 * filesys.c (scm_stat): Slightly optimized.
795 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
797 * ports.c (scm_close_port): Make sure the port is open before
800 * guile-snarf.in: Pass args through to gcc in a way that preserves
801 whitespace boundaries. (Thanks to Greg Badros.)
803 1997-12-02 Tim Pierce <twp@skepsis.com>
805 * stacks.c (scm_frame_procedure): Reverse the logic in the return
806 statement. (Thanks to Doug Evans for pointing this out.)
808 1997-12-01 Tim Pierce <twp@skepsis.com>
810 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
812 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
814 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
815 errno macro expansion of this field name. (errno is a C
816 preprocessor macro on some systems.)
818 1997-11-29 Tim Pierce <twp@skepsis.com>
820 * iselect.c: Doc fix.
822 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
824 * init.c (scm_start_stack): Removed initialization of
825 scm_the_last_stack_var.
827 * backtrace.h: Declare scm_the_last_stack_var.
829 * backtrace.c: Define scm_the_last_stack_var.
831 * root.c (mark_root): Don't mark the_last_stack_var.
833 * root.h (scm_root_state): Removed the_last_stack_var.
835 * throw.c: Added #include "fluids.h"
836 (ss_handler): `the-last-stack' is now a fluid.
838 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
839 --> the_last_stack_fluid.
841 * backtrace.c: Added #include "fluids.h"
842 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
843 (scm_backtrace): `the-last-stack' is now a fluid.
845 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
846 after scm_init_fluids.
848 1997-11-28 Tim Pierce <twp@skepsis.com>
850 * iselect.c: #ifdef USE_THREADS around thread-related includes.
852 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
853 DLSYM_ADDS_USCORE to decide whether to add an underscore.
855 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
857 * iselect.c (coop_next_runnable_thread,
858 coop_wait_for_runnable_thread): Disable interrupts so that no
859 async is executed before a potential error_revive.
860 (scm_internal_select): Disable interrupts during the parts of the
861 code which manipulate the sleep queue and the file descriptors.
863 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
865 * Makefile.am: Added iselect.c and iselect.h.
867 * coop.c (coop_qinit): Initialize fields used by
869 (coop_qget, coop_qget, coop_tmp_queue): Made global.
870 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
871 replacement in iselect.c.
872 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
873 coop_join): If GUILE_ISELECT enabled, use
874 coop_wait_for_runnable_thread instead of
875 coop_next_runnable_thread.
876 (usleep, sleep): New replacements for system functions if
877 GUILE_ISELECT is enabled.
879 * coop-threads.h: Declare coop_wait_for_runnable_thread.
881 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
883 * filesys.c: Added #include "iselect.h". Moved FD-macros to
884 iselect.h. Implement Scheme level `select' using
885 scm_internal_select. (See NEWS.)
887 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
889 * init.c: Call scm_init_iselect.
891 * iselect.h, iselect.c: New files. Implements
892 scm_internal_select. (See NEWS.)
894 1997-11-27 Tim Pierce <twp@skepsis.com>
896 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
897 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
898 and scm_must_free, since ultimately the string returned will be copied
899 by scm_makfrom0str anyway. Also, read any characters that may have
900 been pushed onto the port with scm_ungetc.
901 * ports.c (scm_generic_fgets): Same as for scm_fgets.
902 * ioext.c (scm_read_line): Free string after Guilifying it.
903 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
905 1997-11-26 Anthony Green <green@hoser.cygnus.com>
907 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
909 * gh.h: Safely wrap prototypes for c++ usage.
911 1997-11-25 Mark Galassi <rosalia@cygnus.com>
913 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
914 gh_repl (argc, argv).
916 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
918 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
919 and to invoke scm_shell().
920 (gh_launch_pad): took out the loading of boot-9.scm from here,
921 since it is probably best to let the user control that. In fact,
922 gh_repl() now invokes scm_shell() which does that.
924 1997-11-23 Mark Galassi <rosalia@cygnus.com>
926 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
929 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
931 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
932 yesterday's underscore patch. (Thanks to Marius Vollmer for
935 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
937 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
938 DLSYM_ADDS_USCORE is not defined.
940 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
942 * gh_data.c (gh_uniform_vector_length):
943 (gh_uniform_vector_ref): started implementing the uniform types in
946 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
948 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
949 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
951 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
953 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
954 configure.in was changed).
956 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
958 * Makefile.am (modinclude_HEADERS): Include readline.h here.
959 * Makefile.in: Regenerated.
961 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
963 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
964 OPORT is an `open' port, not an output port.
966 * filesys.c (scm_close, set_element, get_element, scm_chown,
967 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
968 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
969 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
970 scm_close_port, scm_port_line, scm_set_port_line_x,
971 scm_port_column, scm_set_port_column_x, scm_port_filename,
972 scm_set_port_filename_x, scm_port_mode,
973 scm_close_all_ports_except, scm_set_current_output_port,
974 scm_set_current_error_port): Likewise
975 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
976 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
978 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
979 * backtrace.c (display_backtrace_body): Likewise
980 * fports (scm_setvbuf): Likewise
981 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
982 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
983 scm_getpeername, scm_send, scm_sendto): Likewise
984 * unif.c (scm_uniform_array_write): Likewise
986 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
988 Minor problems with substring-related tag changes.
989 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
990 exactly what we want to leave in to detect substrings.
991 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
992 * tags.h: Fix diagrams and comments describing the S tag bit;
993 remove vestigial remarks about the D tag bit.
994 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
995 * strings.c: Formatting tweaks.
997 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
998 variable first; then SCHEME_LOAD_PATH, with a warning message.
999 (scm_parse_path): New function.
1000 * script.c: Doc fixes.
1002 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
1004 Readline support, from Daniel Risacher.
1005 * readline.c, readline.h: New files.
1006 * init.c: #include "readline.h".
1007 (scm_boot_guile_1): Call scm_init_readline, if we have it.
1008 * Makefile.am (libguile_la_SOURCES): Include readline.c.
1009 * Makefile.in: Regenerated.
1010 * scmconfig.h.in: Regenerated, after change to ../configure.
1012 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1014 * gh.h: gh_vector_set -> gh_vector_set_x
1016 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
1018 * gh_data.c (gh_vector_set_x): changed name to make it consistent
1019 with the ! -> _x mapping when going from Scheme to C.
1021 1997-10-19 Mark Galassi <rosalia@cygnus.com>
1023 * gh.h (gh_reverse):
1031 (gh_assoc): added these gh_ functions implemented as macros.
1033 * gh_predicates.c (gh_null_p):
1034 (gh_string_equal_p): added these two missing predicates.
1036 * gh_list.c (gh_append):
1041 (gh_set_cdr_x): added these routines as I go through and try to
1042 complete the picture R4RS functions that should be mirrored in the
1045 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1047 * tags.h (scm_tc7_substring): Changed the comment and code to
1048 conform with the changes below. Folks! We have suddenly two new
1049 free tc7 codes!!! Jummy, jummy!
1051 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
1053 * Makefile.in: Rebuilt.
1054 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
1056 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
1057 * unif.c (scm_vector_set_length_x): Don't handle multibyte
1059 * tag.c (scm_utag_mb_string, scm_utag_mb_substring): Removed.
1060 (scm_tag): Don't handle multibyte strings.
1061 * read.c: Don't include mbstrings.h.
1062 (scm_lreadr): Don't handle multibyte ports.
1063 * kw.c: Don't include mbstrings.h.
1064 * init.c: Don't include mbstrings.h.
1065 (scm_boot_guile_1): Don't init mbstrings module.
1066 * hash.c (scm_hasher): Don't handle mbstrings.
1067 * gscm.c (gscm_run_scm): Don't init mbstrings module.
1068 * gc.c (scm_gc_mark): Don't handle mbstrings.
1069 (scm_gc_sweep): Likewise.
1070 * eval.c (SCM_CEVAL): Don't handle mbstrings.
1071 * eq.c (scm_equal_p): Use SCM_TYP7S, not SCM_TYP7SD.
1072 * tags.h (SCM_TYP7SD): Removed.
1073 (SCM_TYP7D): Removed.
1074 (scm_tc7_mb_string): Removed.
1075 (scm_tc7_mb_substring): Removed.
1076 * print.c (scm_iprin1): Handle char printing directly. Don't
1078 Don't include "mbstrings.h".
1079 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
1080 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
1082 Don't include "mbstrings.h".
1083 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1084 (SCM_SYMBOL_SLOTS): Define as 4.
1085 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
1086 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
1087 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
1088 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
1089 struct.c, threads.c, throw.c, unif.c, variable.c: Use new
1090 ("gen"-less) I/O function names.
1091 * ports.c (scm_add_to_port_table): Don't set port's
1093 * ports.h (scm_port_representation_type): Removed.
1094 (scm_string_representation_type): Removed.
1095 (struct scm_port_table ): Removed representation field.
1096 (SCM_PORT_REPRESENTATION): Removed.
1097 (SCM_SET_PORT_REPRESENTATION): Removed.
1098 * genio.h: Use new function names.
1099 * genio.c: Don't include "extchrs.h".
1100 (scm_gen_putc, scm_gen_puts, scm_gen_write, scm_get_getc):
1102 (scm_putc, scm_puts, scm_lfwrite): No longer static.
1103 (scm_getc): No longer static; handle line and column changes.
1104 (scm_ungetc): Renamed from scm_gen_ungetc.
1105 (scm_do_read_line): Renamed from scm_gen_read_line.
1106 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
1107 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
1109 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1111 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1113 * gh_test_c.c (c_vector_test): some improvements on the vector
1116 * gh.h (gh_vector): this used to exist but do the wrong thing.
1117 Now it (almost) does the right thing, though it takes a list
1118 instead of the individual arguments. I need to see how it could
1120 (gh_list_to_vector): added this function as a macro. Corresponds
1121 to Scheme's (list->vector ...).
1122 (gh_vector_to_list): added this function as a macro. Corresponds
1123 to Scheme's (vector->list ...).
1125 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1126 gh_vector_ref, so that it resembles the Scheme routines more.
1127 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1128 resembles the Scheme routines more.
1129 (gh_make_vector): this used to be (stupidly) called gh_vector().
1130 This is the right name, since it does the same thing as the Scheme
1131 (make-vector ...) procedure.
1133 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1135 * ports.h: #include "libguile/print.h"
1137 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
1138 Some indentation fixes.
1140 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1141 longer a user field; New field: class_flags.
1143 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
1145 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
1147 * gh_data.c (gh_bool2scm): new function which replaces
1148 gh_int2scmb(), which is now tagged as obsolete.
1150 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1152 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1153 macros should by convention not test for NIMPness.)
1154 (SCM_COERCE_OPORT): Adjust indentation.
1156 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1157 SCM_NIMP test before SCM_PRINT_STATE_P.
1159 * struct.c, struct.h, gc.c: Renamed:
1160 scm_struct_i_layout --> scm_vtable_index_layout
1161 scm_struct_i_vcell --> scm_vtable_index_vcell
1162 scm_struct_i_vtable --> scm_vtable_index_vtable
1163 scm_struct_i_printer --> scm_vtable_index_printer
1164 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1166 * struct.c (scm_print_struct): Use new printer slot; Default
1167 printing: Also output hex code of vtable so that type identity
1168 will be indicated as well.
1169 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1170 Removed struct_printer_var; Removed struct-vtable-offset;
1171 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1172 vtable-offset-user): New constants.
1174 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1175 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1176 If this slot contains a procedure, use that to print structures of
1177 the type represented by this vtable.
1179 * print.c (scm_iprin1): Don't print arguments of macro
1180 transformers. (They are always: exp env.); Bugfix: Unmemoize
1181 transformer source with correct environment.
1183 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1185 Streamlining of call-with-dynamic-root:
1187 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1188 there is now only one catch.
1189 (cwdr_outer_body): Removed.
1190 (cwdr_handler): New function.
1191 (scm_internal_cwdr): New function to perform the function of cwdr
1192 but take args that are more useful to C code. Also, the handler
1193 is now invoked *outside* of the new dynamic root, like the docs
1194 say. We no longer have to catch absolutely all errors, the caller
1195 is responsible for using a handler that does not throw, if he
1197 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1198 * root.h (scm_internal_cwdr): New prototype.
1200 Even more but risky streamlining:
1202 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1203 allocation of the jumpbuf of a root continuation. The changes
1204 below are controlled by it. They are now deactivated.
1205 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1206 the JMPBUF of the scm_rootcont to NULL before returning.
1208 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1209 when they are non-NULL.
1210 (scm_gc_mark): Likewise, mark only when non-NULL.
1212 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1213 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1215 * gc.c (scm_done_malloc): New function.
1216 gc.h (scm_done_malloc): New prototype.
1218 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
1219 (struct scm_print_state) [revealed]: New field.
1220 (scm_print_state_vtable): Make visible to the outside world for
1221 type checking purposes.
1222 (scm_valid_oport_value_p): New prototype.
1224 * print.c (scm_valid_oport_value_p): New function to check whether
1225 a certain value is acceptable as a port argument.
1226 (scm_print_state_vtable): New variable.
1227 (scm_free_print_state): Set `revealed' field to false.
1228 (scm_iprin1): Call user supplied closure printer with
1229 scm_printer_apply. Print in the traditional way when there isn't
1230 one or when it returns #f.
1231 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1232 Accept a port/print-state pair in addition to just a port.
1233 (scm_prin1): Don't return the print_state to the pool when it has
1235 (scm_printer_apply): Set `revealed' field of print_state to true.
1236 (scm_init_print): Set scm_print_state_vtable.
1237 (print_state_fluid, print_state_fluid_num): Removed.
1239 * throw.h (scm_handle_by_proc_catching_all): New prototype
1240 throw.c (scm_handle_by_proc_catching_all): New function
1242 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1244 * Makefile.in: Regenerated with automake 1.2c.
1246 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1248 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1249 was looping endlessly.
1251 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1253 * strports.c (scm_eval_string): Don't close the port.
1255 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1256 former returns a nice normal integer. (Thanks to Daniel
1259 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1261 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1262 makefile variable as a build parameter called LIBS. The
1263 build-guile program will use this, for the time being.
1264 * Makefile.in: Regenerated.
1266 Thanks to Shiro Kawai:
1267 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1268 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1271 * Makefile.in: Regenerated with automake 1.2a.
1273 * script.c (scm_compile_shell_switches): If we hit the -c or --
1274 arguments, don't set the car of (command-line) to scm_usage_name,
1275 the prettified name of the guile executable; give it the full
1276 path, the way shells usually handle $0.
1278 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1280 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1281 Scheme-level name `array-map' and renamed `serial-array-map' to
1282 `serial-array-map!'.
1284 * backtrace.c: Introduced exception handlers which now enclose
1285 `display-error' and `display-backtrace' so that error reporting
1286 won't get into infinite loops if an error occurs during displaying
1287 of the error. This can very easily happen with user supplied
1288 print call-back routines.
1290 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1292 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1293 the names `serial-array-map' and `array-map' should be removed.)
1295 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1297 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1298 Added #include "objects.h"
1300 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1301 Add #include "feature.h".
1303 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1304 (modinclude_HEADERS): Added objects.h.
1306 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1307 This test is needed at many places in the code and should be
1308 abstracted. (Motivated by the need of this test in libguiletk.)
1310 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1311 (scm_eval_string), load.c (scm_primitive_load,
1312 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1313 Use SCM_EOF_OBJECT_P.
1315 * eval.c (scm_init_eval): Add feature `delay'.
1317 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1319 * scmhob.h: Removed.
1321 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1323 * list.h (SCM_LISTn): New macros. Make list creation in C code
1324 prettier. The idea comes from STk.
1326 * sequences.h, sequences.c, append.h, append.c: Removed. These
1327 files implemented non-R4RS operations which would encourage
1328 non-portable programming style and less easy-to-read code.
1330 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1333 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1334 sequences.h, #include append.h.
1336 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1339 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1341 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1343 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1345 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1347 * eval.c: Added #include "objects.h"
1349 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1352 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1353 adjacent smob numbers.
1355 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1357 * procprop.h: Added declaration of scm_i_inner_name.
1359 * gsubr.c: New global symbol scm_i_inner_name.
1361 * debug.c (scm_procedure_name): Try procedure property
1362 `inner-name' if `name' fails.
1364 * print.c (scm_iprin1): Use scm_macro_name.
1366 * eval.c (scm_m_define): Give names to macros as well; Only the
1367 first top-level definition gives a procedure/macro a name.
1368 Otherwise confusing names can turn up in backtraces.
1369 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1370 `name'; Give names to macros as well.
1372 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1373 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1376 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1378 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1380 (prinmacro): Removed. The code has been moved/merged into print.c
1381 in order to decrease code redundancy. We want macros to print in
1382 a way equivalent to procedures, and it would be silly to duplicate
1383 the required code. (We don't want to maintain two places.)
1384 (macrosmob): Print field is now a NULL pointer.
1386 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1387 scm_macro_transformer): New prototypes.
1388 (scm_tc16_macro): Declared.
1390 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1391 are now printed in a way equivalent to procedures.
1393 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1395 * procs.h (scm_closure_p): Added declaration.
1397 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1399 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1400 Shouldn't pass "heap" as the subr name.
1402 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1404 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1405 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1406 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1407 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1408 SCM_BOOL_T. Any non-false value is true.
1410 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1412 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1413 scm_gensym): Added prototypes.
1415 * symbols.c (scm_gensym): New function. This will speed up
1416 certain types of applications (such as macro systems) which
1417 generate lots of symbols.
1419 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1421 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1423 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1425 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1426 specifier, since (2) or (2 . 3) would cause SEGV.
1427 (scm_transpose_array): more argument checking fixes.
1429 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1431 * Makefile.in: Regenerated.
1433 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1435 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1437 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1439 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1441 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1443 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1444 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1447 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1448 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1449 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1450 scm_array_p, scm_array_rank, scm_array_dimensions,
1451 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1452 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1453 scm_array_prototype): Added case scm_tc7_wvect.
1455 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1457 * errno.h: prototype for scm_strerror.
1458 * error.c (scm_strerror): new procedure.
1460 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1462 * list.c (scm_list_append_x): Allow non-pair as last argument.
1463 This is consistent with the R4RS append and is probably the
1464 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1466 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1468 * stime.h: prototype for scm_times.
1469 * stime.c (scm_times): new procedure.
1470 * ioext.c (scm_fseek): if the first argument is a file descriptor
1472 (scm_ftell): if the first argument is a file descriptor call lseek
1474 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1475 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1477 (scm_chown): if the first argument is a port or file descriptor,
1479 (scm_truncate_file): new procedure.
1480 Add DEFER/ALLOW INTS to a few other procedures.
1481 (scm_fsync): new procedure.
1482 (scm_open_fdes): new procedure.
1483 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1485 (scm_fcntl): the first argument can now be a file descriptor. The
1486 third argument is now optional.
1488 * posix.c (scm_execl, scm_execlp): make the filename argument
1489 compulsory, since omitting it causes SEGV.
1490 (scm_sync): return unspecified instead of #f.
1491 (scm_execle): new procedure.
1492 (environ_list_to_c): new procedure.
1493 (scm_environ): use environ_list_to_c. disable interrupts.
1494 (scm_convert_exec_args): take pos and subr arguments and
1495 improve error checking.
1497 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1499 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1500 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1501 argument to SCM_ASSERT. Furthermore, the name of the function
1502 should be passed as first argument when signalling
1503 SCM_WNA. (Thanks to Thomas Morgan)
1505 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1506 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1507 dispatches on the number of actual args has a default case
1508 reporting an internal error. This is a vestige from a version
1509 that mallocated a SCM vector to hold the arguments. In the
1510 current version this check is too late: if it ever happens we will
1511 have already overstepped the bounds of the array.
1513 Also, the patch [...] adds a check for too many actual arguments."
1515 mdj: Removed check for "internal programming error".
1517 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1519 * gh_io.c (gh_write): New function.
1521 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1522 throw.c (scm_internal_stack_catch): New sibling to the other catch
1523 functions. Code moved from gh_eval.c.
1524 throw.h: Added header.

1666 but that should be much less likely.

1711 DEBUG_EXTENSIONS isn't #defined.
1713 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>

1740 have to do this explicitly. Also, if regexp/basic is supplied, then
1741 turn off REG_EXTENDED.
1742 (scm_init_regex_posix): New regexp/basic symbol.
1743 (REG_BASIC): #define this if it is not already present.

1790 (cwdr_outer_body): New function, to establish the user's handler,
1791 and pass control to cwdr_inner_body.

1802 across this. Only works on GCC. Otherwise, we hope for the best.
1803 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
1804 the feeling that real thread systems will not need this...
1806 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
1808 Try to detect when people are using one version of libguile and a

1820 primitive definitions under their Scheme names.
1822 * Makefile.am (libguile_la_LDFLAGS): Update library version to
1823 1:2. Helps avoid confusion between installed and uninstalled libs.
1825 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
1828 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
1829 backslash from definition; this should be used like: GDB_INTERFACE;

1833 * ioext.c (scm_duplicate_port): bug fix: don't try to make the

1838 * ports.h: new prototype.

1848 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
1850 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA

1854 * tag.c (scm_tag): Remove unreachable statement.
1855 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
1856 top of the word, it should be unsigned.
1858 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
1859 is defined, to avoid warnings; it's only used in the
1860 conflict-checking code. Which might go away anyway.
1861 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
1862 conditionals; put the label definition in an #if too, to stifle
1865 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
1866 ChangeLog-threads in the distribution.
1867 * Makefile.in: Regenerated.

1877 * load.c (scm_init_load_path): Append $(datadir)/guile to

1908 (scm_lookupcar): Implement in terms of scm_lookupcar1.
1909 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
1912 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
1914 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
1915 supplied. (Change from Tim Pierce.)
1917 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
1919 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
1920 23:47:01 1997" changelog: Slots are now initialized with `#f' by
1921 default and not `()'. `#f' is the canonical non-value in Scheme,
1924 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1926 * struct.c (struct_printer): New variable that holds a handle on
1927 the Scheme variable *struct-printer*. This variable can be set by
1928 Scheme code to override the printing of structures.
1929 (scm_print_struct): If struct_printer is set, call it. If it is
1930 not set, or returns #f, print the structure in the old fashion.
1931 Include "eval.h" for scm_apply.
1933 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
1935 * struct.c (scm_struct_ref, scm_struct_set_x): Use
1936 scm_struct_i_n_words to get the number of fields, not
1937 -scm_struct_n_extra_words.
1939 On the route to fancier struct printing:
1940 * struct.c (scm_print_struct): New function to print a structure.
1941 Include "genio.h" to support it. This function doesn't do
1942 anything interesting right now, but I think it should be here
1944 * struct.h: Include "print.h" and add prototype for
1946 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
1947 print structures ourself.
1949 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
1951 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
1952 before applying the handler in case it doesn't return.
1954 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>

1958 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
1961 * posix.c (scm_uname): interpret only negative values as an error.
1962 Solaris normally returns a positive value.
1964 * script.c (scm_compile_shell_switches): if we are not going into
1965 an interactive repl, set scm_mask_ints to zero so that asyncs can
1968 * simpos.c (scm_system): don't ignore/unignore signals around
1971 * posix.c (scm_open_pipe): don't ignore/unignore signals around
1974 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
1975 done in boot-9.scm instead.
1977 * scmsigs.c, async.c: Major rewriting of signal handling code.
1978 (scm_sigaction): new procedure.
1979 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
1981 (scm_raise): return unspecified, throw error on failure.
1983 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1985 * regex-posix.c (scm_init_regex_posix): Register the "regex"
1986 feature, to help boot-9.scm decide whether to import the regex
1989 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1991 * eval.c: Include scmconfig.h at the beginning of the file so that
1992 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
1995 * regex-posix.c: #include "_scm.h" before conditionally #including
1996 <regex.h>; the former defines HAVE_REGCOMP.
1998 * regex-posix.c: #include <regex.h> conditionally, so the file is
1999 CPP'able (for dependency scanning) even on systems that don't have
2002 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2004 Add new R4RS-compliant syntax for keywords.
2005 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
2006 regardless of the setting of the `keywords' read option.
2007 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
2008 can be re-read no matter what the setting of the `keywords' read
2011 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
2013 Add support for POSIX regular expressions.
2015 * regex-posix.c, regex-posix.h: New files. (Some code
2016 is taken liberally from rx/rgx.c in the old Guile dist.)
2018 * init.c: Include regex-posix.h.
2019 (scm_boot_guile_1): Call scm_init_regex_posix.
2021 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
2022 Add regex-posix.[ch] sources.
2023 * Makefile.in: Regenerated.
2025 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
2026 to do this automatically? It didn't for me, bleh.)
2028 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
2030 * fports.c (print_pipe_port): New function.
2031 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
2032 latter doesn't even take the right arguments.
2034 * Makefile.am: Increment shared lib revision number. I think
2035 sometimes the uninstalled Guile finds the installed shared lib;
2036 Gord says doing this might help. As things turned out, I can't
2037 say whether it does.
2038 * Makefile.in: Regenerated.
2040 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
2041 passing it as the closure argument to scm_boot_guile. (Bill
2044 * ports.c (print_void_port, putc_void_port, puts_void_port,
2045 write_void_port, flush_void_port, getc_void_port, close_void_port,
2046 noop0): Use ANSI prototypes instead of K&R declarations, so the
2047 initialization of void_port_ptob gets aggressively type-checked.
2048 Fix arguments of print_void_port and write_void_port. (Bill

2082 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2084 * script.c (scm_find_executable): Use prototype-style definition
2085 here; apparently it's not quite right to have const in a prototype
2086 and then use a K&R declaration. I wonder if stuff like this will
2087 go away if we compile with -Wrequire-prototypes, or whatever that
2088 is... (Bernard URBAN)
2090 * scmhob.h: New text from Bernard URBAN.
2092 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2094 * script.c: Don't #define const on hpux. Configure takes care of
2095 this. (Thanks to Larry Schwimmer.)
2097 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2098 decide whether to #include <unistd.h>, instead of listing a bunch
2099 of systems. Don't #include stdio twice. Removed dyked-out
2100 definition of scm_find_impl_file.
2102 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2104 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2105 library version info to 1:0.
2106 * Makefile.in: Regenerated.
2108 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

2112 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2113 throw.c: Update copyright years; these files have been worked on
2114 significantly in 1997, but only had copyright years for 1996.
2115 Also, change name of copyright holder on some from Mikael
2116 Djurfeldt to Free Software Foundation; he has signed papers
2117 assigning the changes to the FSF.
2119 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2120 reason not to give the user the option.
2122 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2123 Return #f on end-of-file when scanning table (i.e. when called
2124 with no arguments). Try to catch errors, when we can.
2125 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2127 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2128 external declarations. These are useful.
2130 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2132 * posix.c: don't include <sys/select.h> or define macros for
2133 select, since they were not used in this file.
2135 * filesys.c (scm_select): make the fifth parameter microseconds,
2136 not milliseconds. let the fourth parameter be either a real value
2137 or an integer or #f. The first, second and third arguments can
2138 now be vectors: the type of the corresponding return set will be
2140 (set_element, get_element): new static procedures.
2142 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2144 * strports.c (scm_eval_string): New function.
2145 (scm_eval_0str): Trivially re-implemented in terms of
2147 * strports.h (scm_eval_string): New extern decl.
2149 * net_db.c (h_errno): Add extern decl for this.
2151 * fports.c (local_pclose): New function.
2152 (scm_pipob): Use it in the initializer here.
2155 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2156 Use a meaningful error message when signalling an error. For
2157 this, scm_gethost must check h_errno rather than errno.
2159 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2161 * Makefile.in: Regenerated, using automake-1.1p.
2163 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2165 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2166 not SCM_UNSPECIFIED.
2168 * script.c (scm_compile_shell_switches): don't append (quit) if
2170 (scm_shell): call scm_exit_status and exit on the result of the
2173 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2175 Ensure that shared substrings are handled properly when passed to
2176 a system call or other foreign function. Many thanks to Tim
2178 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2179 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2180 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2181 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
2182 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
2183 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2184 (scm_display_error_message): use RO macros when strings may be RO.
2185 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2186 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2187 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

2191 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
2192 scm_strftime), vports.c (scm_make_soft_port): use
2193 SCM_COERCE_SUBSTR to make sure shared substrings are
2196 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2198 * error.c (scm_error): Add newline to error message.
2200 * init.c (scm_init_standard_ports): Doc fix.
2202 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2204 * dynl-shl.c: Completely replaced with new code from Bernard
2207 * script.c (scm_ice_9_already_loaded): New variable.
2208 (scm_compile_shell_switches): Use it.
2210 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2212 * filesys.c (scm_input_waiting_p): add missing third argument to
2215 * stime.c (scm_localtime): copy the result of localtime before
2216 calling gmtime in case they share a buffer.
2217 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2220 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2222 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2224 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2226 * Makefile.am (check-local): New target, which causes 'make check'
2227 to run gh_test_c and gh_test_repl, with some trivial input.
2228 * Makefile.in: Rgnrtd.
2230 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2232 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2235 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2237 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2238 sure how this was supposed to work.
2239 (scm_async_click): don't send SCM_TICK_SIGNAL.
2240 (scm_init_async): don't initialize %tick-thunk.
2242 * the following change doesn't affect the Scheme interface:
2243 gc-thunk is called at the end of garbage collection. however it's
2244 no longer implemented by pretending it's a signal.
2246 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2247 system async corresponding to scm_gc_thunk.
2248 * async.h: declare scm_gc_async.
2249 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2250 gc-thunk directly, instead of going through a signal handler.
2251 (scm_gc_async): new variable, points to the GC system-async.
2252 (scm_init_async): save the GC async as scm_gc_async instead
2253 of using system_signal_asyncs.
2254 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2256 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2258 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2259 Don't screw up if we're interrupted.
2260 * Makefile.in: Regeneradet.
2262 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2264 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2266 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2267 we're not using AM_INIT_GUILE_MODULE any more.
2268 * Makefile.in: Reneregated.
2270 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2272 Functions for finding variable bindings, grace à Tim Pierce.
2273 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2274 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2276 Get 'make dist' to work again.
2277 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2278 * Makefile.in: Regenerated, like a surry without a fringe on top.
2280 Changes for reduced Guile distribution: one configure script,
2282 * configure.in, configure: Removed.
2283 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2284 real configure script lives.
2285 * Makefile.in, scmconfig.h.in: Regenerated.
2287 * init.c: #include "script.h", to get prototype for script.c's
2290 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2292 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2293 scm_must_malloc, not raw malloc.
2295 * script.c (scm_compile_shell_switches): Dyke out debugging output
2298 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2300 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2302 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2303 system has them. Hope this is safe. Previously
2304 sys/timeb.h was included if HAVE_FTIME was defined or if
2305 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2306 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2308 * ioext.c (scm_setfileno): add missing third argument to
2309 scm_misc_error call.
2311 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2313 * eq.c (scm_equal_p): Correctly compare strings of different
2314 varieties. (Thanks to Tim Pierce.)
2316 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2318 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2319 #! block comment must occur on a line all by itself.
2321 Move most of the guts of shell command processing into libguile,
2322 so guile.c can be very small (and eventuallly auto-generated. (I
2323 mean, generated mechanically, not self-generated. Hmm.))
2324 * guile.c, script.c, script.h: New source files.
2325 * init.c (scm_boot_guile_1): Call scm_init_script.
2326 * libguile.h: #include "script.h".
2327 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2328 targets, for new executable.
2329 (libguile_la_SOURCES): Mention script.c.
2330 (modinclude_HEADERS): Add script.h.
2331 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2332 not dynamic linking is enabled. This is because we're generating
2333 executables now. Move CY_AC_WITH_THREADS call after those, so the
2334 values of cy_cv_threads_libs captures the libs chosen above.
2335 * Makefile.in, configure, aclocal.m4: Regenerated.
2337 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2338 We don't maintain this interface any more, and it just confuses
2341 * alloca.c: #include <scmconfig.h>, not <config.h>.
2342 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2343 it'll get included in disties.
2345 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2347 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2348 be distributed, because they confuse people.
2349 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2351 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2353 * configure.in: check for presence of gethostent (not present on
2354 OpenBSD by default).
2355 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2356 * configure, scmconfig.h.in: Regenerated.
2358 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2360 * backtrace.c (scm_backtrace): Split message string across
2361 newlines properly. GCC is more tolerant of this than other
2364 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2366 Merge threads directory into libguile.
2367 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2368 threads.h: New source files.
2369 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
2370 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2372 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2373 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2374 coop-threads.c.cygnus, coop-threads.h.cygnus.
2375 * configure.in: If we're using threads, include threads.o in
2377 * _scm.h, libguile.h: threads.h lives in this directory now.
2378 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2379 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2380 currently used, but brought along for information's sake.
2381 * ChangeLog-threads: log from old 'threads' directory.
2382 * Makefile.in, configure: Rebuilt.
2384 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2386 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2389 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2391 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2393 Merge GH interface library into libguile.
2394 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2395 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2396 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2397 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2399 (EXTRA_libguile_la_SOURCES): ... here.
2400 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2401 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2402 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2403 New variables, describing how to build the gh test programs.
2404 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2405 build the test programs, and we probably should have been linking
2406 libguile.la against them all along, to support AIX shared libs.
2407 Add cflags for threads to CFLAGS; add libs for threads to new
2408 variable THREAD_LIBS, used in Makefile.am.
2409 * ChangeLog-gh: log from old `gh' subdirectory.
2410 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2412 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2414 * acconfig.h: Undo change of Apr 9; including the definition of
2415 PACKAGE in the guile headers conflicts with applications' own
2417 * scmconfig.h.in: Regenerated.
2419 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
2421 * filesys.c (scm_fcntl): New function from Roland McGrath.
2422 (scm_init_filesys): New symbols for use with fcntl.
2423 * filesys.h: Added prototype.
2425 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
2426 when PROC is receiving no arguments.
2428 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2430 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2431 have S_IFSOCK. This is the case under Ultrix.
2433 * posix.c (scm_status_exit_val, scm_status_exit_val,
2434 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2435 Ultrix versions of WIFSTOPPED, etc., which assume that their
2436 arguments are lvalues (hmm).
2438 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2440 * eval.c: Doc fixes.
2442 * throw.c: Doc fixes; rearranged.
2444 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
2446 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
2448 * acconfig.h: Added entry for PACKAGE.
2449 * scmconfig.h.in: Regenerated.
2451 Changes to work with automake-1.1n, which has better libtool support.
2452 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2453 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2455 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2457 * Makefile.in: Rebuild.
2459 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2461 * stime.c (scm_mktime): take an optional zone argument.
2462 (scm_localtime): check putenv return value.
2463 (scm_strftime, scm_strptime): moved from posix.c. move #include
2465 stime.h, posix.h: update prototypes.
2466 (bdtime2c, setzone, restorezone): new static procedures.
2467 (scm_mktime, scm_strftime): use them.
2468 (scm_strftime): don't call mktime before strftime. Use
2469 filltime for return value.
2470 (filltime): convert NULL zname to #f.
2471 (scm_strptime): return a count of characters consumed, not
2472 the remaining string.
2474 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2476 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2477 (scm_mktime): likewise.
2479 Uncomment localtime and mktime.
2481 * configure.in: add AC_STRUCT_TIMEZONE.
2483 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2485 * stime.c (scm_init_stime): don't define ticks/sec.
2486 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2487 return value problem and is still portable.)
2489 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2491 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2492 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2493 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2494 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2495 cpp_err_symbols.c): Corresponding changes.
2496 * Makefile.in: Regenerated.
2498 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2500 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2501 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2502 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2503 * putenv.c: new file, from sh-utils 1.12.
2505 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2506 since allocation isn't for Scheme objects.
2507 (scm_putenv): copy strings before placing in the environment.
2509 * stime.c (scm_current_time): throw an error if time returns -1,
2510 instead of returning #f.
2511 (scm_get_internal_real_time, scm_get_internal_real_time): use
2512 scm_long2num for return value instead of SCM_MAKINUM.
2514 * stime.h: prototypes updated.
2516 * stime.c (scm_time_in_msec): apparently unused, deleted.
2518 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2520 * configure.in: check for gettimeofday.
2522 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2523 which may be more usefully portable than a gettimeofday interface.
2525 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2527 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
2529 * Makefile.in: Regenerated.
2531 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2533 * stime.c (filltime): recovered static procedure.
2534 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2537 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2538 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2540 * posix.c (scm_mknod): split the mode argument into type and perms
2541 arguments, like the extra fields returned by stat.
2543 * fports.c (scm_pipob): set the close, free and print procedures.
2544 (scm_close_pipe): new procedure.
2546 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2547 define them in boot-9.scm
2549 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2551 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2552 wan't defined. Don't include fd.h.
2554 * Previously fd.h was regenerated whenever configure was run,
2555 forcing a couple of files to be recompiled.
2557 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2558 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2559 Check for _fileno as well as _file.
2561 * ioext.c: don't fd.h.
2562 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2565 * Change the stratigy for getting information about errno
2566 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2567 generating lists of symbols during the build process, which will
2568 not always work, include comprehensive lists in the distribution.
2569 To help keep the lists up to date, the "check_signals" and
2570 "check_errnos" make targets can be used.
2572 * configure.in: don't check for a command to extract errno codes.
2573 * Makefile.am: update file lists, remove errnos.list and errnos.c
2574 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2575 check_errnos targets.
2576 (CLEANFILES): remove errnos.c and errnos.list, add
2577 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2578 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2579 * errnos.default: deleted.

2581 * cpp_errno.c: renamed from errnos_get.c.
2582 * cpp_err_symbols, cpp_sig_symbols: new files.
2583 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2584 * error.c (scm_init_error): #include cpp_err_symbols instead of
2586 * posix.c (scm_init_posix): don't intern signal symbols. #include
2589 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2591 * strop.c (scm_i_index): allow the lower bound to be equal to the
2592 length of the string, so a null string doesn't always give an error.
2594 * posix.h: new prototypes.
2595 * posix.c (scm_status_exit_val, scm_status_term_sig,
2596 scm_status_stop_sig): new functions, as in scsh. They break down
2597 process status values as returned by waitpid.
2599 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2601 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2602 configure doesn't know about it.
2604 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2606 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2608 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2609 which defines C variables with global linkage.
2611 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2613 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2616 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2618 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2619 has time to check why this doesn't work well with continuations.
2621 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2623 * Fix shell syntax error; some shells won't tolerate
2624 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2626 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2628 * posix.c (scm_uname): throw an error if uname fails instead
2631 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
2633 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
2636 * async.c (scm_ints_disabled): definition moved from error.c.
2638 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2640 * acconfig.h: Removed PACKAGE.
2642 * scmconfig.h.in: Regenerated.
2644 * snarf.h: g++ says it's non-portable not to specify the first
2645 argument in a varargs declaration. I introduced the first
2646 argument by using preprocessor conditionals.
2648 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
2650 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
2651 (scm_freopen): use RO string macros for filename and modes.
2652 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
2654 * posix.c (scm_getgrgid): simplify conversion of name to C string.
2655 (scm_mknod): use RO string macros for path.
2657 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
2658 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
2660 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2661 use SCM_ROSTRINGP and SCM_ROCHARS.
2663 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2665 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
2668 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
2669 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
2670 support for byte vectors.
2672 * print.c (scm_iprin1): Limit number of vector elements printed
2673 according to pstate->length.
2675 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2677 * backtrace.c (scm_display_error_message): don't segv if message
2680 * error.h: prototype for scm_error_scm.
2682 * error.c (scm_error_scm): new procedure, reimplements scm-error
2683 in C and uses scm_error.
2685 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2687 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
2688 pointer to the Scheme variable read-hash-procedures and intern it
2689 in scm_init_read. Modify scm_read_hash_extend and
2690 scm_get_hash_procedure to use the pointer.
2692 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2694 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
2695 (SCM_KEYWORD_STYLE): defined.
2697 * read.c (scm_read_opts): add a keywords option. This isn't a
2698 boolean option, in case someone wants to add support for DSSSL
2700 Setup scm_keyword_prefix symbol.
2701 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
2703 I've left keyword support disabled by default, since it doesn't
2704 seem to break the module system and it gives R4RS standard behaviour.
2705 It can be reactivated with (read-set! keywords 'prefix).
2707 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2709 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
2710 before constructing arbiter.
2712 * eval.c (scm_m_define): Bugfix: Check that the object is a
2713 closure before setting the procedure property!
2715 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
2717 * ports.c: Removed `ungetc-char-ready?'.
2719 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
2721 * read.c (scm_init_read): intitialise scm_read_hash_procedures
2722 (idea from Mikael: make it a pair so scm_permanent object only
2724 (scm_read_hash_extend): don't call scm_permanent_object.
2725 (ideas from Mikael): if chr is already in the list, replace its
2726 procedure instead of appending it again. If proc is #f, remove
2728 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
2730 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
2732 * gdbint.c (gdb_read): update scm_lreadr usage.
2734 * load.h: update prototypes.
2736 * load.c (scm_primitive_load, scm_read_and_eval_x,
2737 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
2739 * read.h: add prototype for scm_read_hash_extend. Change args for
2742 * read.c (scm_read_hash_procedures): new variable.
2743 (scm_read_hash_extend): new procedure.
2744 (scm_get_hash_procedure): new procedure.
2745 (scm_lreadr): use scm_get_hash_procedure instead of an argument
2746 for extended # processing.
2747 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
2748 scm_read_token): remove case_i, sharp arguments. Change callers.
2750 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
2752 * read.h (SCM_N_READ_OPTIONS): increase to 3.
2753 (SCM_CASE_INSENSITIVE_P): define.
2755 * read.c: add case-insensitive option to scm_read_opts.
2756 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
2757 to determine whether to convert symbol case.
2758 (default_case_i): definition removed.
2759 * read.c (scm_read_token): if case_i, downcase ic before doing
2762 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2764 * configure.in: Added configuration option `guile-debug'.
2765 Configure with --enable-guile-debug if you want a bunch of extra
2766 functions used for debugging when developing Guile.
2768 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
2770 * procs.c (make-cclo): New undocumented debugging procedure: Make
2771 compiled closure with internal procedure PROC and length LENGTH.
2772 Only compiled if GUILE_DEBUG is defined.
2774 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
2776 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
2778 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
2780 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
2781 with 3 or more args internally to the evaluator.
2783 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2785 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
2786 with 3 or more args internally to the evaluator. This is mainly
2787 because we don't want to pass entry and exit points of the
2788 debug support twice, but it also seems to increase the speed of
2789 the evaluator for such calls (e. g. (+ 1 2 3)).
2791 * backtrace.c (scm_display_application): New procedure:
2792 display-application; Set fancy printing parameters individually
2793 for different types of display (backtrace, error, application).
2794 (These should of course be customizable!)
2796 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
2797 clear the CHECK-flags.
2799 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2801 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
2803 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2805 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
2806 from pairs with a GLOC in the car.
2808 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
2809 otherwise `symbol-hash' will behave badly.
2810 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
2811 we get segmentation fault!
2813 * symbols.c: Added #include "weaks.h". New functions:
2814 `builtin-bindings' and `builtin-weak-bindings'. (These will be
2815 moved to an extraneous library when we split libguile.)
2817 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2819 * filesys.c (scm_stat): stat now takes fport arguments too as
2820 documented in the manual.
2822 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2824 * debug.c (scm_single_step): Bugfix: Call continuation with
2825 scm_call_continuation instead of throwing to it.
2827 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
2829 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
2830 argument wasn't declared to be optional.
2832 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2834 * stime.c (scm_init_stime): Add feature "current-time".
2836 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2838 * throw.h: prototype for scm_exit_status.
2839 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
2840 args to derive an exit status. Allows (quit) to work from a
2842 (scm_exit_status): new function.
2845 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2847 * eval.c (scm_deval): Removed some old code.
2848 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
2850 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
2853 * symbols.c (msymbolize): Bugfix: Must initialize property list to
2856 * procs.c: Introduce the existent C function scm_thunk_p at the
2857 Scheme level as well.
2859 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2861 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
2862 used from C to easily lookup the value of a symbol in the current
2865 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2867 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
2868 scm_init_unif in this file. This will also fix a previous problem
2871 * configure.in: Added AM_MAINTAINER_MODE
2873 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2875 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
2878 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
2880 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
2881 source files that are not always included in libguile but should
2882 have their dependencies calculated by automake. This variable is
2883 recognized by automake, no further magic is needed.
2884 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
2885 to deal exclusively with *.lo files, as it seems. The *.o files
2886 are built automatically when the corresponding *.lo file gets
2889 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
2891 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
2894 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
2896 * unif.c (scm_array_set_x): minor change to argument error checking.
2898 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
2900 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
2901 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
2902 They should only be included in the library at configure.in's
2904 (libguile_la_LDADD): Include the appropriate .lo files here.
2905 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
2906 so we know when to build them (and their .lo bretheren).
2907 * configure.in (LIBLOBJS): New substituted variable. We let
2908 configure decide which .o files to include in LIBOBJS, and then
2909 put the corresponding list of .lo files in LIBLOBJS. The latter
2910 is what we pass to libtool.
2911 * Makefile.in, configure: regenerated.
2913 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
2915 * symbols.c (scm_sysintern0): New function. Contains the core of
2916 old scm_sysintern but doesn't take a second value argument.
2917 (scm_sysintern): Now uses scm_sysintern0.
2918 (scm_sysintern_no_module_lookup): Renamed to
2919 scm_sysintern0_no_module_lookup and doesn't take a second value
2920 argument any longer.
2922 * symbols.h (scm_sysintern0: Added declaration.
2924 * options.c (scm_init_opts): Use scm_sysintern0 instead of
2925 scm_sysintern when interning option keys. Otherwise we risk
2926 destroying the values of already interned variables.
2928 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
2929 scheme-level boolean (use SCM_NFALSEP).
2931 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
2933 (scm_backtrace): New function. (C version of old function from
2934 boot-9.scm) Motivation: Make it possible to display backtraces
2935 without depending on boot-9.scm. (I'm uncertain if this
2936 motivation is good enough...)
2938 * root.h (scm_root_state): Add member the_last_stack_var.
2939 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
2941 * root.c (mark_root): Mark scm_the_last_stack_var.
2943 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
2946 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
2948 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
2949 1. mark_lazy_catch didn't mark the smob.
2950 2. Both functions above have standard variants:
2951 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
2952 free_lazy_catch --> scm_free0.
2954 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
2956 * throw.c (scm_internal_lazy_catch): New function.
2957 (scm_lazy_catch): Rewritten to use it.
2958 (scm_ithrow): Handle the new lazy catch representation.
2959 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
2960 that doesn't have a jmpbuf is a lazy catch clause.
2961 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
2962 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
2963 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
2965 (scm_init_throw): Register the new lazy-catch smob type.
2966 * throw.h (scm_internal_lazy_catch): decl for new function.
2968 * throw.c (scm_internal_catch): Doc fixes.
2970 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
2971 configure.in. Including this might cause problems if applications
2972 that link against libguile include their own copies of alloca, but
2973 if they're using autoconf, they should be adding libguile to LIBS
2974 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
2975 the copy in libguile, and things will be okay. (I think.)
2977 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2979 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
2981 strop.h: move prototypes too.
2983 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2985 * posix.c (scm_init_posix): don't intern EINTR since it's now done
2988 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
2989 etc. I deleted them from filesys.c long ago, but didn't
2990 notice they were here too (although ineffective since
2991 sys/stat.h wasn't included).
2993 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
2995 * eval.c: Don't define alloca in GCC case. gcc will automatically
2996 use __builtin_alloca if appropriate.
2998 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
3000 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
3001 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
3002 that values of automatic variables are preserved. See comments
3003 for safe_setjmp for details.
3005 Change from Thomas Morgan:
3006 * variable.c: Include eq.h.
3007 (var_equal): New function.
3008 (variable_smob): Use var_equal as the discriminator for variables.
3010 * throw.c (s_throw): Remove extraneous declaration.
3012 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
3013 * eval.c: Add necessary CPP cruft to support that.
3014 * configure, Makefile.in, scmconfig.h.in: regenerated.
3016 Change from Thomas Morgan:
3017 * procprop.c (scm_procedure_properties): Convert the Scheme
3018 boolean returned by scm_procedure_p into a C boolean before using
3019 it as a condition for SCM_ASSERT.
3020 (scm_procedure_property): Likewise.
3022 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
3023 indications of Unixness.
3026 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
3028 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
3030 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
3032 * read.c (scm_lreadr): use scm_misc_error to improve one of the
3033 "unknown # object" error messages.
3035 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
3036 (scm_i_index) and declare it static. Add a 'direction' argument
3037 to indicate what way the search should go.
3038 (scm_i_index): throw out-of-range error instead of wrong-type-arg
3040 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
3041 strop.h: remove scm_i_index, scm_i_rindex prototypes.
3043 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
3045 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
3047 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
3048 to avoid clash with various scsh forks.
3050 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
3052 The following two changes (ramap.c, throw.c) are motivated by the
3053 apparent unportability of forward declarations of static arrays of
3054 the form `static foo bar[];'.
3056 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
3057 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
3059 * throw.c (scm_throw): Moved above scm_ithrow.
3061 * options.h: Removed the extern declarations of scm_yes_sym and
3062 scm_no_sym since these are static.
3064 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
3066 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
3068 * Makefile.am: remove AWK=@AWK@.
3069 Add a rule for generating errnos.list.
3070 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
3072 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
3073 don't extract errnos, just set a variable (avoids the
3074 need to recompile error.c just because configure is run.)
3076 * unif.h: update prototypes.
3077 * unif.c (scm_uniform_array_read,write): change the offset and
3078 length arguments to start and end, for consistency.
3080 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
3082 * ioext.h: update prototypes.
3083 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3084 scm_read_line_x, it's a more general procedure using an
3085 interface from scsh. read-line and read-line! are now defined
3087 Note that the new read-line trims the terminator
3088 by default, previously it was appended to the returned string. An
3089 optional argument specifies how to process the terminator (scsh
3090 compatible). For the old behaviour: (read-line port 'concat).
3091 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3092 returns a pair, but is converted to multiple values if the scsh
3095 socket.h: update prototypes.
3096 * socket.c (scm_recvfrom): for consistency with other procedures,
3097 take start and end as separate optional arguments.
3098 (scm_recv, scm_recvfrom): don't allow the second argument
3099 to be a size, only a buffer. Change the scheme names to
3100 recv! and recvfrom!. Don't return the buffer.
3102 * ioext.h, posix.h: move prototypes too.
3103 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3104 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3105 "read.h" and "unif.h".
3106 * ioext.c: include "chars.h"
3108 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3110 * dynl.c: The dynamic linking and module registration functions
3111 are now defined even when dynamic linking is not available for the
3112 host system. Some of their functionality can be done without
3113 dynamic linking; when it's really needed, they throw errors.
3115 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3117 * configure.in: Only define DYNAMIC_LINKING when one of the system
3118 dependent functions is detected.
3119 * dynl.c (scm_dynamic_func): New function to get the address of a
3120 function in a dynamic object.
3121 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3122 produced by scm_dynamic_func as the thing to call.
3124 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3126 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3127 (scm_register_module_xxx, scm_registered_modules,
3128 scm_clear_registered_modules): New functions.
3130 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3132 * symbols.c (scm_sysintern): Renamed to
3133 scm_sysintern_no_module_lookup.
3134 (scm_sysintern): New function to take the place of the old
3135 scm_sysintern. It uses the current toplevel lookup closure to give
3136 the symbol its value. This is a temporary hack to put packages
3137 like gtcltk into their own module.
3138 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3139 us whether `scm_top_level_lookup_closure_var' has been initialized
3141 * eval.c (scm_init_eval): Set it.
3143 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3145 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3146 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3148 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3150 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3151 scm_sys_dup): deleted: FD capability will be added to other
3153 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3154 scm_fd_free, fd_smob, scm_intern_fd.
3155 (scm_open): renamed from scm_sys_open. Return a port instead of
3156 an FD object. Make the mode argument optional.
3157 (scm_sys_create): deleted, it's just a special case of open.
3158 (scm_init_filesys): move interning of constants O_CREAT etc.,
3159 here (were previously using SCM_CONST_LONG macro).
3160 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3162 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3163 include "fports.h" and <stdio.h>
3164 (scm_stat, scm_select): don't support FD objects.
3166 * error.h: adjust scm_syserror_msg prototype.
3167 * error.c (scm_syserror_msg): take an extra argument for errno.
3168 Using the global value didn't always work, since it could be
3169 reset by procedure calls in the message or args arguments.
3171 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3172 I don't understand why the check was there (and what about the
3175 * strop.c (scm_string_copy): allow shared substrings to be copied.
3177 * unif.h: corresponding change to prototypes.
3178 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3179 recognize two new optional arguments: offset and length. Allow
3180 the port argument to be an integer (file descriptor, for scsh).
3181 Include <unistd.h> for "read" prototype.
3183 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3185 * socket.c: don't include filesys.h.
3187 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3189 * Makefile.am: add AWK=@AWK@ (?)
3191 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3193 Add a rule to generate errnos.c from errnos.
3194 * error.c (scm_init_error): include errnos.c.
3195 * errnos_cnvt.awk: new file, converts the list of errno codes to
3197 * errnos_get.c: new file.
3198 * errnos.default: new file, contains errnos to try if they can't
3199 be extracted from errno.h.
3200 * configure.in: if using GCC, try and extract errno codes from
3204 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3206 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3207 * Makefile.am: Made libguile into a libtool library.
3208 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3209 Set libtool_libs to indicate that libguile is a libtool library.
3210 See guile/ChangeLog for details.
3211 * .cvsignore: ignore "*.lo", the libtool library objects.
3213 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3215 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3216 use htons in getservbyport argument.
3218 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3220 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3221 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3224 * objprop.c (scm_object_property): No need to take the CDR of the
3225 value returned by scm_object_properties, since Aug 20 change.
3227 * configure.in: When checking for struct linger, #include
3228 <sys/types.h> as well as <sys/socket.h>. I've never known
3229 <sys/types.h> to cause any portability problems, and Solaris's
3230 <sys/socket.h> needs it.
3231 * configure: Rebuilt.
3233 I think the Sun compiler has chosen a perverse way to interpret
3234 ANSI declarations combined with K&R definitions. We'll
3235 appease it a little bit. But when it invades France, we fight.
3236 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3237 * print.h (scm_iprlist): Here too.
3238 * numbers.c (scm_divbigdig): Change definition to match
3239 declaration in numbers.h.
3240 * unif.c (scm_makflo): Change definition to match declaration in
3243 * init.c (scm_boot_guile): Don't return the value of
3244 scm_boot_guile_1. This function doesn't return a value;
3245 scm_boot_guile_1 doesn't return a value (or return at all).
3247 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3250 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3251 compile. I have a feeling this function is a bad idea anyway ---
3252 one should always test for features, not systems.
3254 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3255 semicolons. Only pure luck kept this from being noticed earlier.
3257 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3259 * socket.c (scm_recvfrom): Added missing semicolon.
3261 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3263 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3264 the buffer and start and end positions for scsh networking
3267 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3269 * configure.in: Revert previous change to this file; the problem
3270 is due to transient automake weirdness.
3271 * configure: Rebuilt.
3273 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3274 PLUGIN/guile.libs. configure generates the latter from the former.
3275 * Makefile.in: Rebuilt.
3277 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3278 need this if we install scripts, like guile-snarf.
3279 * configure: Rebuilt.
3281 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3283 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3285 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3287 * socket.c (scm_addr_vector): fix faulty scm_listify.
3289 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3291 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3292 style block comment is no longer considered an error.
3294 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3296 * PLUGIN/guile.libs.in: New file.
3297 * PLUGIN/guile.libs: Removed from repository.
3298 * configure.in: Create PLUGIN/guile.libs from
3299 PLUGIN/guile.libs.in. This is for including additonal libraries
3300 needed for dynamic linking.
3301 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3302 instead of PLUGIN/guile.libs.
3304 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3306 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3308 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3309 occurrences of the given element from the list, not just the
3310 first. This is how the Emacs Lisp functions behave, how the
3311 analogous Common Lisp functions behave, and (I believe) how the
3312 older Maclisp functions worked. I realize that this change may
3313 break code, but it seemed better to break it before the Guile
3316 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3317 Their prototypes were already present in gc.h, but they weren't
3319 (scm_init_storage): Initialize scm_protects.
3320 * root.c (scm_protects): New element of scm_sys_protects.
3322 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3324 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3326 * libguile.h: Added #include "libguile/net_db.h".
3328 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3329 30 change. That file is only meant for communication between the
3330 configuration process and load.c. If code linked against libguile
3331 wants to get at the paths mentioned in libpath.h, it can call
3332 functions declared in load.h.
3334 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3336 * libguile.h: Removed #include "libguile/fdsocket.h"
3338 * net_db.c: Added #include <sys/socket.h>.
3340 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3342 * filesys.c (scm_input_waiting_p): use select in preference to
3343 FIONREAD, since the latter doesn't detect EOF.
3344 Throw error if neither select nor FIONREAD available.
3346 * socket.c (scm_connect): take a port, not a fd object.
3347 (scm_fill_sockaddr): throw an error if fam is not recognised.
3348 (scm_bind): use scm_fill_sockaddr.
3349 (scm_listen): take a port, not a fd object.
3350 (scm_accept): take and return a port. return #f in the car if
3351 address can't be got
3352 (scm_sock_fd_to_port): new procedure.
3353 (scm_socket): use scm_sock_fd_to_port.
3354 (scm_addr_vector): throw error if unrecognised address type.
3355 take an extra argument with the calling procedure name.
3356 (scm_getsockname): take a port. return #f if address can't be got.
3357 (scm_getpeername): take a port. return #f if address can't be got.
3358 (scm_recvfrom): take a port. return #f for address component if can't
3360 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3361 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3363 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3365 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3366 use separate data pointers, to allow them to be designed
3367 independently and reused.
3368 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3369 Renamed from catch_body, catch_handler, and uncaught_throw; made
3371 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3373 (scm_catch): Use the above.
3374 (scm_throw): Don't bother printing a message for an uncaught
3375 throw; we establish a default handler in init.
3376 * throw.h (scm_internal_catch): Prototype updated.
3377 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3379 (struct scm_body_thunk_data): New structure, used as data
3380 argument to scm_body_thunk.
3381 * init.c (struct main_func_closure): New structure, packaging up
3382 the data to pass to the user's main function.
3383 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3384 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3385 scm_internal_catch to establish a catch-all handler, using
3386 scm_handle_by_message. This replaces the special-case code in
3388 (invoke_main_func): Body function for scm_internal_catch; invoke
3389 the user's main function, using the main_func_closure pointer to
3390 decide what to pass it.
3391 * root.c (struct cwdr_body_data): Remove handler_proc member.
3392 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3393 (cwdr_handler): Removed.
3395 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3397 * socket.h (SCM_P): update bind prototype.
3398 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3399 include "feature.h".
3400 (scm_socket): return a port, not a file descriptor object.
3401 include "fports.h" and <unistd.h>
3402 (scm_bind): take a port, not a file descriptor object.
3403 take an extra argument for address args.
3405 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3406 INADDR_NONE, INADDR_LOOPBACK.
3408 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3410 * init.c: include net_db.h and not fdsocket.h.
3411 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3413 * Makefile.am: corresponding changes.
3414 * socket.h: renamed from fdsocket.h, fix names.
3415 * net_db.h: renamed from socket.h, fix names.
3416 * socket.c: renamed from fdsocket.c.
3417 remove _sys from procedure names.
3418 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3419 add "socket" to features list.
3420 * net_db.c: renamed from socket.c.
3421 remove _sys from procedure names.
3422 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3423 add "net-db" to features list.
3424 include "net_db.h". don't include <sys/socket.h> or
3427 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3429 * tags.h (scm_tags): Removed comma at end of last enumerator.
3431 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3433 Don't use GCC extensions to allocate space for debugging frames.
3434 (Here he goes again! Why do we put up with this?!)
3435 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3436 an scm_debug_info structure, not an in-line array of them. Add
3437 'info' member, to say how many vect elements we've used, for eval
3439 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3440 a new variable debug_info_end to mark the end of vect, instead of
3441 the address of the 'info' pointer itself.
3442 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3443 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3444 (SCM_APPLY): Explicitly allocate space for debug.vect.
3445 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3446 * stacks.c: Adjusted for new debug frame structure.
3447 (RELOC_INFO, RELOC_FRAME): New macros.
3448 (stack_depth, read_frames): Use them, and new scm_debug_frame
3449 element 'info', instead of magically knowing that eval frames have
3450 an info pointer sitting after vect.
3451 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3453 (scm_init_stacks): Formatting tweaks.
3455 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3457 Give GCC more control flow information, so it can be sure that
3458 variables aren't used uninitialized.
3459 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3460 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3461 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3462 scm_misc_error): Tell GCC that these functions never return.
3463 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3464 out the field type, call abort if SCM_ASSERT returns, to placate
3466 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3467 scm_wta ever returns. We can't handle this case anyway, and this
3468 gives the optimizer more information.
3469 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3470 scm_wta ever returns.
3472 In some cases, the code is fine, but GCC isn't smart enough to
3473 figure that out; this usually happens when one variable is only
3474 initialized and used when a particular condition holds true, and
3475 we know that condition will never change within a given invocation
3476 of the function. In this case, we simply initialize the variables
3477 to placate the compiler, hopefully to a value which will cause a
3478 crash if it is ever actually used.
3479 * print.c (scm_iprin1): Initialize mw_pos.
3480 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3481 * throw.c (scm_ithrow): Initialize dynpair.
3482 * unif.c (scm_uniform_vector_ref): Initialize cra.
3483 * struct.c (init_struct): Initialize prot.
3484 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3486 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3487 if EXPR contains no expressions.
3489 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3491 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3492 cause an infinite loop (???). So much for the algebraic
3493 equivalency of variable-sized arrays and alloca...
3495 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3497 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3498 a SCM boolean, not a C boolean.
3500 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3502 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3503 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3504 rules for raising scm_mtrigger. Previously, unfortunate but not
3505 unlikely circumstances could result in almost constant invokation
3506 of the gc. Now, this situations should be less likely, but they
3507 are not prevented completely.
3509 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3511 * numbers.c (scm_fuck): Procedure removed; looks like old test
3513 * numbers.h: Prototype removed.
3515 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3517 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3518 array to a pointer, to match my Nov 21 change in eval.c.
3520 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3522 * libguile.h: Added #include "libguile/backtrace.h", #include
3523 "libguile/stacks.h".
3525 * strings.c (scm_string scm_make_string scm_string_ref
3526 scm_string_set_x scm_string_equal_p scm_string_append):
3527 Bugfix according to scm patch from Aubrey Jaffer:
3528 Corrected long-standing
3529 (not (eqv? (integer->char 128)
3530 (string-ref (make-string 1 (integer->char 128)) 0)))
3531 bug found by John Kozak <jk@noontide.demon.co.uk>.
3533 * strports.c, strports.h: Make scm_eval_0str return the value of
3534 the last expression evaluated (previously, it returned void).
3536 * strports.c, strports.h: New function: scm_read_0str. Does what
3539 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3541 * simpos.c (scm_getenv): return #f if string can't be found in the
3542 environment instead of throwing an exception, for compatibility
3543 with numerous other systems.
3545 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3547 * Makefile.am (.c.x): Use guile-snarf.
3548 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3550 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3552 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3554 * backtrace.c (scm_display_error_message): Made non-static, and
3555 renamed from display_error_message.
3556 * backtrace.h (scm_display_error_message): Added extern decl.
3557 * throw.c (uncaught_throw): Use it to display the error message.
3559 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3561 * inet_aton.c: Use #if 0, not #ifdef 0.
3563 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3565 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3566 to convert the returned value.
3567 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3568 the offset argument.
3570 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3572 Add new interface to catch/throw, usable from C as well as
3574 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3575 (scm_internal_catch): New function, replaces...
3576 (scm_catch_apply): Deleted.
3577 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3578 mechanism which is a bit more code, but can be used nicely from C
3579 and implement the Scheme semantics as well.
3580 (scm_internal_catch): This is the replacement; it's named after
3581 the analogous function in Emacs.
3582 (scm_catch): Reimplemented in terms of the above.
3583 (struct catch_body_data, catch_body, catch_handler): New
3584 functions, used by scm_catch.
3585 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3586 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3587 support for new cwdr.
3589 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3592 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3594 * acconfig.h: Added DYNAMIC_LINKING symbol.
3595 * configure.in: Add option and checks for dynamic linking.
3596 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3597 dynl.h: New files for dynamic linking support.
3598 * Makefile.am (libguile_a_SOURCES):
3600 (modinclude_HEADERS): Added "dynl.h".
3601 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3603 * init.c (scm_boot_guile_1): Call
3604 scm_init_dynamic_linking to initialize dynamic linking support.
3606 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3608 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3609 (as we Schemers say). It needs to be global, so that I can tweak
3610 it for the proper operation of unexec.
3611 (scm_boot_guile_1_live): New variable, see above.
3613 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3615 * guile-snarf.sh: Removed.
3616 * PLUGIN/guile.libs: Added dependency for -lm.
3617 * acinclude.m4: Renamed from aclocal.m4.
3618 * PLUGIN/greet: Removed.
3619 * Makefile.am, aclocal.m4: New files.
3620 * configure.in: Updated for Automake.
3622 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3624 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3625 and not top_level_lookup_thunk_var.
3627 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3629 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3631 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3633 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3634 Scheme function, instead of syntax. Single argument is now a
3637 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3639 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3640 scm_ra_divide): Properly terminate statements passed as arguments
3641 to IVDEP macros. (Thanks to Bernard Urban.)
3643 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
3644 with non-constant sizes. (Thanks to Bernard Urban.)
3646 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3648 It's an "eval closure", not an "eval thunk." A thunk is a
3649 function of no arguments.
3650 * root.h (struct scm_root_state): Renamed
3651 top_level_lookup_closure_var from top_level_lookup_thunk_var.
3652 (scm_top_level_lookup_closure_var): Renamed from
3653 scm_top_level_lookup_thunk_var.
3654 * root.c (mark_root): Uses changed.
3655 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
3656 * init.c (scm_start_stack): Uses changed.
3657 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
3658 Change scheme-visible name to *top-level-lookup-closure* from
3659 *top-level-lookup-thunk*.
3661 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
3663 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
3664 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
3666 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
3668 * gc.c (struct scm_heap_seg_data): Doc fixes.
3670 * gc.c (scm_gc_sweep): Empty all segments' freelists before
3671 sweeping. Then, prepend each segment's free cells to its
3672 freelist, rather than wiping out the old value. (Thanks to Marius
3675 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
3676 scm_check_freelist, scm_debug_newcell): New functions and
3677 variables, for debugging freelist problems.
3678 * pairs.h (SCM_NEWCELL): New debugging version added.
3679 * gc.h (scm_debug_newcell): Added extern declaration, used by
3680 debugging version of SCM_NEWCELL.
3682 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3684 On some systems <libc.h> conflicts with <unistd.h>, and should not
3685 be #included at all.
3686 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
3687 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
3688 * configure.in: Call it.
3689 * posix.c, filesys.c: Use its results to decide whether or not to
3691 * configure, scmconfig.h.in: Rebuilt with autoconf and
3694 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3696 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
3697 pointer to the stdio stream before calling scm_setbuf0, so the
3698 latter will be able to retrieve it. I'm surprised this didn't
3699 segfault earlier. (Thanks to Christopher Lee.)
3701 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3703 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
3706 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3708 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
3709 number of stack narrowing specifier pairs. The first specifier in
3710 a pair controls inner border, the second the outer border. A
3711 number means cut that number of frames, a procedure object means
3712 cut until that object is found in operator position in a frame.
3714 * root.c (cwdr): Bugfix.
3716 * read.c: Recording of positions disabled by default.
3718 * procs.c (scm_closure_p): New function.
3720 * posix.c (scm_tmpnam): New function.
3722 * load.c: Added #include "throw.h".
3723 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
3726 * load.c, load.h (scm_read_and_eval_x): New function.
3728 * eval.c: Renamed debug option "deval" to "debug".
3730 (scm_eval_x): `eval!' is no longer accessible from the scheme
3731 level. Motivation: We can't allow operations which introduce
3732 glocs into the scheme level. Guile's type system can't handle
3733 these as data. Use `eval' or `read-and-eval!' as replacement.
3735 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
3736 SCM_CONSP since this is a macro!; Set vframe.prev to
3737 scm_last_debug_frame instead of 0. In this way we can look
3738 "above" the virtual start stack frame if we wish.
3739 (scm_debug_hang): New function: Useful for debugging Guile in
3740 certain tricky situations. Will probably be removed later...
3742 * debug.h: Changed semantics of debug option "backtrace". This
3743 option now only indicates whether we want automatic backtrace at
3746 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3748 * ports.c: #include "filesys.h"
3749 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
3751 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
3752 Motivation: This is system specific code which is related to file
3753 I/O. It also may use select. Added code by Gary Houston to
3754 detect presence of character in stdio buffers.
3756 * libguile.h: #include "libguile/libpath.h"
3758 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
3759 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
3760 SCM_SITE_DIR; Install libpath.h among the other include files.
3762 * load.c, load.h (scm_sys_package_data_dir): New function.
3764 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3766 * stacks.h: Bugfix: Don't use tail-array length field as stack
3767 length field! This screwed GC.
3769 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3771 * _scm.h: Added #ifndef around definition of macros min and max.
3773 * __scm.h: Added hooks for threads to plugin to in ints protection
3774 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
3775 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
3776 the main code in these macros duplicated and spread over multiple
3777 files. Renamed SCM_THREADS_SWITCHING_CODE ->
3778 SCM_THREAD_SWITCHING_CODE.
3780 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
3782 * snarf.h: New file.
3783 * guile-snarf.sh: New file.
3784 * Makefile.in (inner_h_files): Added snarf.h
3785 (ancillary, install, uninstall, distclean): Added actions for
3787 (.c.x): Use guile-snarf.
3788 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
3789 (gen_c_files): Note that these depend on guile-snarf.
3790 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
3791 now in "snarf.h". Added #include "snarf.h" to get them.
3792 * libguile.h: Added #include "snarf.h".
3793 (Patches applied and tweaked by Jim Blandy.)
3795 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3797 * socket.c: Use K&R style declaration for 'close'; the GNU coding
3798 standards suggest against providing prototypes for system
3799 functions. Thanks to Greg Troxel.
3801 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3803 * strports.c (scm_eval_0str): New function.
3804 #include "read.h", to get prototype for scm_read.
3805 * Makefile.in (strports.o): Update dependencies.
3806 * strports.h: New prototype.
3808 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
3809 scheme name from "int?" to "integer?". It seems to do the job.
3810 * numbers.h: Rename prototype too.
3811 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
3814 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
3815 scm_num_eq_p): Rename these according to R4RS conventions: call
3816 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
3817 to making libguile R4RS compliant without ice-9...
3819 * load.c (scm_sys_search_load_path): Search for files under all
3820 extensions listed in the %load-extensions variable. If FILENAME
3821 is absolute, return it unchanged, without searching the load path.
3822 (scm_loc_load_extensions): New variable, pointing to
3823 %load-extensions' value cell.
3824 (scm_init_load): Initialize it, and the value it points to.
3825 (scm_primitive_load_path): Improve error reporting.
3827 * load.c (scm_loc_load_hook): New variable, pointing to value cell
3828 of new Scheme variable %load-hook.
3829 (scm_primitive_load): Apply %load-hook to filename.
3831 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
3833 * configure.in: add tests for figuring out whether buffered data
3834 is available in a FILE structure, which is needed by char-ready.
3836 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
3839 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
3840 exceptions using misc_error instead of syserror. It seems a bit
3841 odd to throw an exception if a string can't be found in the
3842 environment, but it's consistent with open-file, stat etc.
3843 (simpos.h): remove sys_ from getenv.
3845 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
3846 occurs, throw an error instead of returning errno. Return value
3848 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
3850 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
3852 * filesys.c (scm_stat2scm): derive file type and permissions from
3853 the stat mode and append them to the returned vector.
3854 There isn't much overhead in doing this and it avoids the need to
3855 work with S_IRUSR et al. in Scheme.
3856 Define symbols scm_sym_regular etc.
3857 (scm_init_filesys): don't intern S_IRUSR etc.
3859 * load.c: change s_try_load and s_try_load_path to s_primitive_load
3860 and s_primitive_load_path.
3862 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
3864 * error.h: don't declare error symbols. prototype for scm_misc_error.
3866 * stackchk.c (scm_stack_overflow_key): defined here instead of in
3869 * error.c: use SCM_SYMBOL to set up error keys.
3870 scm_misc_error: new procedure.
3872 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3874 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
3875 between `#!' and `!#' is ignored.
3876 (skip_scsh_block_comment): New function.
3878 * feature.c (scm_set_program_arguments): New argument, FIRST.
3879 * feature.h: Update prototype.
3880 * init.c (scm_boot_guile_1): Pass new argument to
3881 scm_set_program_arguments.
3883 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3885 * init.c (scm_start_stack): Don't initialize scm_progargs here.
3886 (scm_boot_guile): Call scm_set_program_arguments here, later than
3887 the old initialization.
3889 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
3890 initialization procedure.
3891 - Delete in, out, err arguments; there are other perfectly good
3892 ways to override these when desired.
3893 - Delete result argument; this function shouldn't ever return.
3894 - Rename init_func argument to main_func, for less confusion.
3895 - Delete boot_cmd argument; main_func is more general.
3896 -Add 'closure' argument, to help people pass data to main_func
3897 without resorting to global variables.
3898 - Abort if reentered; don't bother returning an error code.
3899 - Call scm_init_standard_ports to set up the default/current
3900 standard ports; no need to pass them to scm_start_stack.
3901 - Remove code to evaluate the boot_cmd, and start the repl; let
3902 the user do something like that in main_func if they want.
3903 - Remove code to package up a return value; main_func can do any
3905 - Call exit (0), instead of returning.
3906 (scm_start_stack): Don't initialize the I/O ports here; that's
3907 weird. Delete in, out, err arguments. Move guts to
3908 scm_init_standard_ports, scm_stdio_to_port.
3909 (scm_init_standard_ports): New function, to set up current and
3910 default standard ports.
3911 (scm_start_stack, scm_restart_stack): Make these static.
3912 * init.h (scm_boot_guile): Adjust declaration.
3913 (scm_start_stack, scm_restart_stack): Remove externally
3914 visible declarations for these.
3915 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
3917 * fports.c (scm_stdio_to_port): New function. Its guts used to be
3918 written out several times in scm_start_stack.
3919 * fports.h: New declaration for the above.
3921 * feature.c (scm_set_program_arguments): New function.
3922 * feature.h: New declaration for the above.
3924 * ports.c: Formatting tweak.
3926 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
3928 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
3929 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
3930 for obtaining the address of a car or cdr field. Motivation:
3931 &SCM_CXR make assumptions about the internal structure of the
3934 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
3935 Motivation: see SCM_CXRLOC.
3937 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
3938 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
3939 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
3940 Motivation: Safer use. Some other macros are defined in terms of
3941 these operations. If these are defined using the SCM_SETCXR
3942 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
3943 to inefficiency and an <e1> with side-effects could potentially
3944 break. Also, these particular operations are heavily utilized in
3945 the garbage collector. In unoptimized code there will be a
3948 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
3949 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
3950 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
3951 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
3952 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
3953 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
3954 vports.c: Cleaned up use of pairs: Don't make any special
3955 assumptions about the internal structure of selectors and
3956 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
3957 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
3958 (Among other things, this change makes it easier to build Guile
3959 with certain compilers which have problems with casted lvalues.)
3961 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3963 * stacks.c: Improve selection of relevant stack frames when making
3964 a stack object. Introduce one level of indirection in the stack
3965 object to make it possible to "narrow" to a certain region of the
3966 stack. This facilitates making use of more clever algorithms (not
3967 implemented) for selecting relevant frames and gives a cleaner
3968 design since selection of frames can be done independently of
3969 extraction of frames from the real stack.
3970 (scm_stack_id): Also take #t as argument which means look at
3973 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
3974 Turn n_tail into an integer directly representing current number
3975 of frames in stack. Add field tail.
3977 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
3979 * debug.c (scm_make_memoized): Made it available at scheme level.
3980 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
3981 SCM_NIMP before applying heavier predicates in argument checking.
3982 (scm_local_eval): Also take memoized object as argument.
3984 * backtrace.c (scm_display_error): Just a safety measure: Stacks
3985 aren't created with zero length, but should such a strange
3986 creature suddenly turn up...
3988 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
3990 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
3991 `del', for the sake of C++ compilers. (Patch applied by JimB.)
3993 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
3995 * variable.c (scm_make_variable): Make the name hint optional, as
3997 (anonymous_variable_sym): Renamed from variable_sym. All uses
4000 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
4001 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
4002 of scm_primitive_load_path was also changed to
4003 "primitive-load-path", from "%try-load-path". Callers changed.
4004 We'd like to respect the convention that a function named
4005 "try-mumble" should behave just like the function called "mumble",
4006 but return #f instead of signalling some error.
4007 * load.h: Rename prototypes.
4009 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4011 * print.c (make_print_state, grow_print_state), print.h: Modified
4012 the print state representation: Don't use a tail array for
4013 recording of circular references. Resizing of the print state
4014 structure invalidates the print state pointer. To avoid passing
4015 around an indirect print state reference to all printing
4016 functions, we instead let the print state reference a resizable
4019 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
4021 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
4022 Don't crash when passed an improper list terminated by a
4023 non-immediate value.
4025 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
4027 Allocate data for structures on an eight-byte boundary, as
4028 required by the tagging system.
4029 * struct.c (alloc_struct): New function.
4030 (scm_make_struct, scm_make_vtable_vtable): Call it.
4031 * struct.h (scm_struct_n_extra_words): Bump to 3.
4032 (scm_struct_i_ptr): New "field".
4033 * gc.c (scm_gc_sweep): When we need to free the data, use the
4034 information stored by alloc_struct to find the beginning of the
4035 block allocated to the structure, so we can free it.
4037 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4039 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
4042 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
4043 (scm_debug_info): New member: id.
4045 * stacks.c: Stacks are now represented as structs; Stacks have an
4046 id given to them by `start-stack'.
4047 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
4049 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
4050 Changed stack representation.
4052 * debug.c (scm_procedure_name): Try procedure property `name' for
4053 compiled closures aswell.
4055 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
4057 * eval.c: scm_i_name moved to gsubr.c
4058 (scm_m_define): Record names of all kinds of procedure
4059 objects. (Earlier, only closures were recorded.)
4061 * procprop.h: Added declaration of scm_i_name.
4063 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
4064 (scm_make_gsubr): Record names of compiled closures.
4066 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4068 * debug.c, debug.h: Removed obsolete code.
4070 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
4071 stacks.c: Renamed regs --> scm_contregs.
4073 * print.c (scm_free_print_state): Cleanup print state before
4074 returning it to pool. It is better to do it here than in
4075 scm_prin1 since scm_prin1 is called often.
4077 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
4078 s_set_source_property_x): Check that first argument is a pair or a
4081 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
4082 scm_i_line, scm_i_column and scm_i_breakpoint global.
4084 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4085 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4088 * debug.h: Added debug object smob declaration and macro
4091 * configure.in: Build with backtrace.o and stacks.o if debug
4094 * Makefile.in: Added entries for new files: backtrace.c,
4095 backtrace.h, stacks.c and stacks.h.
4097 * symbols.c (scm_sym2ovcell): Fixed documentation.
4099 * _scm.h (min, max): Added.
4101 * async.c: Moved `min' macro to _scm.h.
4103 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4104 SCM_BACKTRACE_INDENT.
4106 * eval.c: Added new debug options `maxdepth' and `indent'.
4108 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4110 * print.h: Added selector SCM_PRINT_STATE.
4112 * print.c: New functions: scm_make_print_state,
4113 scm_free_print_state.
4115 * print.h: Added declarations for scm_make_print_state,
4116 scm_free_print_state.
4118 * debug.c (scm_m_start_stack): New acro.
4120 * debug.h: Small cleanup.
4122 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4125 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

4147 declare functions with prototypes. (Patch thanks to Marius
4150 More prototype-related changes from Marius Vollmer:
4151 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4152 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4153 * ports.h (ptobfuns): Added prototypes. This means some casting in
4155 * fports.c: Added casts for initializations, since the functions
4156 are defined to take FILE * as their stream argument, not SCM.
4157 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4158 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4159 to `char *str_data' to conform to prototype.
4161 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4163 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4165 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4167 * stime.c, stime.h: use SCM_P method.
4169 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4171 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4172 be given at least two arguments. Insist that lst's last element
4173 be a list, but don't make any requirements of its predecessors.
4175 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4177 * eval.c (scm_nconc2last): Revert last change; there seems to be
4178 other stuff going on here.
4180 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4182 * eval.c (scm_nconc2last): Make sure that each element of lst
4183 (which is a list of argument lists, except for the tail) is a
4184 proper list, i.e., finite and terminated by '().
4186 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4188 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4191 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4192 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4195 * vectors.c (scm_make_vector): Fill vectors with the undefined
4196 value, to help make Guile Scheme code more portable to other
4199 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4200 * symbols.h, tags.h: Doc fixes.
4202 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4204 * async.c (scm_take_signal): Doc fixes.
4206 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4208 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4209 want to subtract it from the modulus; we just want to leave it
4212 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4214 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4217 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4219 * throw.c (scm_catch_apply): Finished implementation of
4222 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4224 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4226 (scm_init_filesys): set "i/o-extensions" feature.
4229 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4231 * Makefile.in (root.o): Correct dependencies.
4233 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4235 * Makefile.in: Added dependency entry for root.o.
4237 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4238 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4240 * init.c (scm_start_stack): Set initial root continuation number
4243 * procs.c: New function: scm_thunk_p.
4245 * procs.h: Added declarations of scm_thunk_p.
4247 * root.c: Renamed `call-with-new-root' -->
4248 `call-with-dynamic-root'.
4249 (cwdr): Removed allocation of new root state. This should be done
4250 separately by use of scm_make_root.
4251 (scm_apply_with_dynamic_root): New function: Does what it
4252 sounds like. Needed when spawning threads.
4254 * root.h: Added member last_debug_frame to root state.
4255 Added #include "libguile/debug.h"
4257 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4258 arguments. The motivation is that code in root.c needs catch
4259 functionality, and we want to avoid code duplication.
4260 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4261 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4262 handlers that run without popping the stack into the dynwind
4265 * throw.h: Added prototypes for scm_catch_apply and
4268 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4270 * root.h (scm_root, scm_set_root): Decouple thread support details
4271 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4272 SCM_SET_THREAD_LOCAL_DATA.
4274 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4275 and tortoise scanning loop.
4277 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4279 * Makefile.in: Rebuild dependencies.
4281 * libguile.h: #include "libguile/print.h" before "smob.h", since
4282 the latter uses the print_state structure.
4284 * throw.c (scm_ithrow): Use the correct variable when checking to
4285 see if a given element of scm_dynwinds is a valid catch.
4287 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4288 structure, abort; don't just silently ignore the garbage.
4290 * _scm.h: #include "print.h" here, since it seems to be used just
4292 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4293 strports.c, unif.h: Don't #include "print.h".
4295 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4297 * feature.h (scm_loc_features): Removed external declaration.
4298 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4300 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4302 * feature.c (scm_init_feature): Added threads feature (needs to be
4303 initialized here, since features doesn't exist when
4304 scm_init_threads is called).
4306 * libguile.h: Added #include "libguile/../threads/threads.h".
4307 (This is a kludge to get thread support working. This should be
4310 * configure.in, acconfig.h: Added flags for thread support.
4312 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4315 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4316 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4319 * _scm.h: Added conditional #include "threads.h"
4321 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4322 SCM_THREADS_SWITCHING_CODE.
4324 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4325 allocate the basic dynamic root object.
4326 (scm_boot_guile): Added call to scm_init_root.
4328 * root.c, root.h: Added root smob.
4329 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4330 functions: Implements dynamic roots mostly according to spec in
4331 SCM manual. Main difference is that the second argument is a
4332 throw handler rather than an error "thunk".
4334 * root.h: Added declaration of scm_init_root.
4336 * root.c: Added #include "genio.h", #include "smob.h", #include
4337 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4339 (scm_init_root): Added #include "root.x".
4341 * throw.c: Added #include "stackchk.h"
4342 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4343 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4344 can be used in scm_call_with_new_root; Added reenabling of stack
4345 checking when catching a throw.
4347 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4349 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4351 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4352 element is not found, as per R4RS.
4354 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4356 * list.c: Doc fixes throughout.
4358 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4360 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4361 declare the char * to be const. Avoids a warning in rgx.c.
4363 * ports.h: spelling fix.
4365 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4368 * load.c (scm_sys_try_load_path): throw an error if file not found
4369 (like it says it in NEWS).
4371 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4373 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4374 PROPS slot to '(), not #f; it's an empty alist.
4376 * throw.h, throw.c: Use SCM_P instead of #if hair.
4378 Remove special support for uncaught throws; see throw.c for
4380 * throw.c (uncaught_throw): New function.
4381 (scm_ithrow): Call uncaught_throw if we don't find a throw
4382 target; don't mess with scm_bad_throw_vcell.
4383 (scm_bad_throw_vcell): Variable deleted.
4384 (scm_init_throw): Don't initialize it.
4386 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4389 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4391 * numbers.c (scm_istr2int): If the number is short (as most
4392 numbers are), just call scm_small_istr2int to deal with it.
4393 (scm_small_istr2int): New function, created by un-#ifdefing the
4394 non-bignum version of scm_istr2int and renaming it.
4396 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4398 * load.c (scm_sys_try_load): don't check whether value returned
4399 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4400 Change the Scheme name from %try-load to primitive-load.
4402 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4403 Can avoid passing a message, allowing it to be derived in the
4404 error handler (e.g., if we want to throw to the key both from
4407 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4409 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4410 references now have a new appearance which is more compact and
4411 also gives a clue about what the target of the reference is.
4412 By setting parameters in the print state, more fancy printing can
4413 be achieved. This is used by the (not yet commited) backtrace
4416 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4418 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4421 * print.c: Added #include "struct.h". Removed function
4424 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4425 scm_iprin1. Removed prototype for scm_prlist.
4427 * arbiters.c (prinarb),
4428 async.c (print_async),
4429 debug.c (prindebugobj, prinmemoized),
4430 eval.c (prinprom, prinmacro),
4431 filesys.c (scm_fd_print, scm_dir_print),
4433 mallocs.c (prinmalloc),
4434 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4435 smob.h (scm_smobfuns),
4436 srcprop.c (prinsrcprops),
4438 unif.c, unif.h (scm_raprin1, rapr1),
4439 variable.c (prin_var): Changed argument `int writing' to
4440 `scm_print_state *pstate'.
4442 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4443 that it will be called before scm_init_print.
4445 * print.c (scm_prin1): Print states are now allocated when calling
4446 scm_prin1 and then passed around to all printing functions as an
4447 argument. A cache `print_state_pool' enables reuse of print
4449 (scm_make_print_state): New function.
4450 (scm_iprin1): Adaption to print states.
4451 (scm_iprlist): An initial "hare and tortoise" scan brings down
4452 time complexity to O (depth * N). (Better time complexity will be
4453 achieved when the printing code is completely rewritten.)
4455 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4457 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4458 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4459 it gets done whether or not the cache variable has a value.
4461 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4463 Distinguish #f and ().
4464 * __scm.h: #undef SICP.
4465 * pairs.h (SCM_EOL): Delete this definition, equating it with
4467 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4468 the value it used to have. Doc fixes, too.
4470 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4472 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4473 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4474 Lord's implementation of structs, allowing for tail arrays as
4475 described in the manual. Also fixed some bugs. (Both the interface
4476 and the implementation should be improved.)
4478 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4480 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4481 People who whish to see the source can do `(print-enable 'source)'.
4482 Removed #ifdef DEBUG_EXTENSIONS.
4484 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4486 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4487 integer (assuming for now accepting an integer is a good thing).
4489 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4490 %S will be used instead for write'ing arguments.
4492 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4493 asserts. fix a few other asserts.
4494 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4495 scm_uniform_vector_ref, scm_array_set_x,
4496 scm_dimensions_to_unform_array): change args in
4497 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4498 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4499 scm_substring_fill_x): likewise.
4500 gsubr.c (scm_gsubr_apply): likewise.
4501 eval.c (SCM_APPLY): likewise.
4503 * eval.c (4 places): replace scm_everr with lgh_error or
4506 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4507 scm_memory_error): new procedures.
4508 scm_everr: deleted. can use scm_wta, dropping first two args.
4509 scm_error: convert NULL subr to SCM_BOOL_F.
4511 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4514 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4517 * error.c, error.h: new error keys: scm_arg_type_key,
4518 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4520 scm_wta: reimplement using lgh_error instead of scm_everr.
4522 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4524 * gdbint.c: scm_lread now has one more argument.
4526 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4527 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4528 loading source from non-file ports, which, e. g., happens when
4529 using the Emacs interface).
4531 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4534 * read.c: Added code for recording of positions of source code
4535 expressions; New functions: recsexpr, scm_lreadrecparen;
4536 _scm_make_srcprops --> scm_make_srcprops
4537 (scm_flush_ws): Removed updating of positions counters. This work
4538 is already done by scm_gen_getc
4540 * read.h: Added prototype for scm_lreadrecparen
4542 * print.c: Added #include "alist.h"
4544 * eval.c: Added #include "hash.h"
4546 * eq.c: Added #include "ramap.h"
4548 * options.c: Documentation fixes.
4550 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4551 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4552 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4553 --> scm_make_srcprops
4555 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4556 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4557 function calls in the definition of the whash access macros.
4559 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4561 * init.c (scm_boot_guile): Add level of indirection to
4562 scm_boot_guile_1() to ensure that stack base pointer is properly
4563 initialized. There was no guarantee that variable i was the
4564 highest/lowest variable on stack (i.e. the call frame of
4565 scm_boot_guile was not completely protected from gc).
4567 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4569 * ports.h (scm_port_table): put back file_name, it will be used to
4570 support debugging. Undo related changes in fports.c, ioext.c,
4573 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4575 * ports.h (scm_port_table): remove file_name member for now, it seems
4577 * fports.c (scm_open_file): don't set file_name in PTAB.
4578 (prinfport): don't use file_name in PTAB.
4579 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4580 * ports.c (scm_add_to_port_table): don't intialize file_name.
4581 (scm_port_file_name): remove for now.
4582 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4584 * fports.h (scm_mkfile): prototype deleted.
4585 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4587 * debug.c, unif.c: use scm_out_of_range instead of
4588 wta for range errors (ASSERT still needs work).
4590 * error.c, error.h (scm_out_of_range): new procedure.
4592 * error.c, error.h (scm_out_of_range_key): new key.
4594 * posix.c (scm_sync): #else was missing.
4596 * error.c, error.h: append _key to names scm_num_overflow and
4599 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4600 of consing an empty list.
4601 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4602 of macros, saves code and string space.
4603 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4604 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4605 lower case. Rename scm_syserror_m to scm_syserror_msg.
4606 error.h: prototypes for new procedures.
4608 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4610 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4612 * error.c, error.h: setup scm_num_overflow key.
4614 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4615 Remove definition of SCM_OVSCM_FLOW.
4617 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4619 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4620 explicit message and args.
4622 * error.c, error.h, __scm.h: change system_error_sym to
4625 * error.c (system_error_sym): remove leading %% from the Scheme name
4628 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4630 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4632 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4633 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4634 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4635 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4636 renamed. (These were introduced by unsupervised name
4639 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4641 * print.c: Added code for detection of circular references during
4642 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4643 a hook for printing of closures (accessible via print options).
4644 This leads to a split of calls to scm_iprin1 into two classes:
4645 elementary print operations (e. g. the code which prints a smob)
4646 still use scm_iprin1 while top level calls (like scm_display) use
4647 scm_prin1. scm_prin1 begins by clearing the data structure used
4648 to record reference information.
4650 * print.h: Added declarations of scm_prin1 and scm_prlist.
4652 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
4654 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
4656 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
4658 * error.c (err_head): scm_iprin1 --> scm_prin1
4660 * debug.c: Adjusted header comment.
4664 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4666 * strerror.c: Doc fix.
4668 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4670 * gdbint.c (gdb_read): Now possible to run during GC.
4671 (unmark_port, remark_port): New functions.
4673 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
4675 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
4676 of allocating a new string object. Also, increase size by
4677 the factor 2 instead of 1.5.
4679 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
4681 * __scm.h (SCM_P): Corrected to run under traditional C.
4683 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
4686 * async.c: Calls to scm_sysintern corrected.
4688 * async.h (scm_async_clock): Redundant declaration removed.
4690 * continuations.c (scm_dynthrow): Redundant declaration removed.
4692 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
4693 Definition typos corrected.
4695 * debug.h: Missing declarations of functions in debug.c added
4698 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
4699 Missing declarations to functions in eval.c added.
4701 * filesys.c: Possibly uninitialized variable rv.
4703 * gc.h (scm_object_addr, scm_unhash_name): Missing
4704 declarations of functions defined in gc.c added.
4706 * genio.c: Possible typos str_data -> wstr_data. ???
4708 * genio.c: Possibly unintended shadowing of local variable
4709 `int c' (gotos out of scope of inner `c'). ???
4711 * init.c: Uninitialized `SCM last' may be used.
4713 * ioext.h: (scm_sys_isatty_p): Typo.
4715 * list.h (scm_list_head): Missing prototype for function in
4718 * numbers.c (scm_two_doubles): Changed from extern to static
4719 (is used only within numbers.c).
4721 * numbers.h: Repeated declarations removed.
4723 * ports.h (scm_close_all_ports_except): Declaration for the
4724 function defined in ports.c added.
4726 * posix.h: Missing declarations added.
4728 * procs.h (scm_make_subr_opt): Missing declaration added.
4730 * socket.h (scm_sys_gethost): Missing declaration added.
4732 * socket.h: Redundant declarations removed (they are in fdsocket.h).
4734 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
4735 Missing declarations added.
4737 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
4739 * struct.c: Uninitialized variable `SCM answer' may be used.
4741 * unif.c (l2ra): Declaration prototype.
4743 * unif.c (scm_array_equal_p): Dummy definition removed (it is
4744 defined in ramap.c).
4746 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
4747 Redundant declarations removed (they are in ramap.h).
4749 * variable.h (scm_make_udvariable,
4750 scm_make_undefined_variable): Declaration corrected to
4751 correspond variable.c.
4753 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
4754 Missing declarations added.
4756 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
4758 * Makefile.in (distclean): Don't forget to delete fd.h.
4760 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4762 * fd.h.in, tags.h: Trivial cleanups.
4764 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
4765 marksweep.h just declared functions from gc.c.
4766 * gc.h, libguile.h: Don't #include "marksweep.h".
4767 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4768 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
4769 dependencies updated.
4771 * libguile.h: Don't #include "files.h"; it's been deleted.
4773 * files.c (scm_sys_delete_file): Moved to filesys.c.
4774 File is now empty; deleted.
4776 * filesys.c: scm_sys_delete_file is now here. Remove
4777 #if's; they seem to rely on remnants of an old portability
4778 regimen. If the problems come up again, solve them properly,
4779 using autoconf. Specifically: Don't test M_SYSV, and #define
4780 remove to be unlink if it's #defined; don't use remove just
4781 because HAVE_STDC_HEADERS is #defined.
4782 * filesys.h: Add declarations for scm_sys_delete_file.
4783 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4784 files.o, files.h, files.c, and files.x.
4785 * init.c: Don't #include "files.h", and don't call scm_init_files.
4787 Use SCM_P instead of PROTO; the latter intrudes on the user's
4789 * params.h: Deleted; definition of SCM_P moved to...
4790 * __scm.h: ... here, where it replaces PROTO macro.
4791 * libguile.h, smob.h: Don't #include "params.h".
4792 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
4793 smob.h: Fix prototypes accordingly.
4794 * Makefile.in: Update dependencies.
4795 (inner_h_files): Remove params.h.
4797 * gc.c: #include "gc.h"; every module should include its header,
4798 to let the compiler cross-check the declarations against the
4801 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
4802 simpos.h: #include "libguile/__scm.h".
4804 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
4806 * init.c: Don't forget to #include smob.h and init.h.
4807 * Makefile.in: Dependencies updated.
4809 * smob.h: Use PROTO instead of #if __STDC__.
4811 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
4813 * __scm.h: Doc fixes.
4815 * __scm.h, libguile.h: Use "quotes" in the #includes, not
4816 <angles>; this allows `make depends' to work properly.
4818 * libguile.h: #include smob.h and pairs.h before the others; they
4819 define typedefs used by other headers.
4821 C files should #include only the header files they need, not
4822 libguile.h (which #includes all the header files); the pointless
4823 recompilation was wasting my time.
4824 * Makefile.in (all .o dependency lists): Regenerated.
4825 * libguile.h: Don't try to get a definition for size_t here...
4826 * __scm.h: Do it here.
4827 * _scm.h: Since this is the internal libguile header, put things
4828 here that all (or a majority) of the libguile files will want.
4829 Don't #include <libguile.h> here; that generates dependencies on
4830 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
4831 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
4832 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and
4834 * alist.c: Get "eq.h", "list.h", "alist.h".
4835 * append.c: Get "append.h", "list.h".
4836 * arbiters.c: Get "arbiters.h", "smob.h".
4837 * async.c: Get "async.h", "smob.h", "throw.h", "eval.h".
4838 * boolean.c: Get "boolean.h".
4839 * chars.c: Get "chars.h".
4840 * continuations.c: Get "continuations.h", "dynwind.h", "debug.h",
4842 * debug.c: Get "debug.h", "feature.h", "read.h", "strports.h",
4843 "continuations.h", "alist.h", "srcprop.h", "procprop.h", "smob.h",
4844 "genio.h", "throw.h", "eval.h".
4845 * dynwind.c: Get "dynwind.h", "alist.h", "eval.h".

4929 * weaks.c: Get "weaks.h".
4931 * stackchk.h: #include "libguile/debug.h",
4933 * print.h, read.h: #include "options.h", since everyone who uses
4934 either of these files will need that.
4936 * smob.h: #include "ports.h", "genio.h", and "print.h", since
4937 anyone who uses this file will need them to define the smob
4938 printing functions. Also, get markers.h, since people will need
4939 to #define the mark functions.
4941 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
4942 * ports.h: ... to here.
4944 * ports.h (scm_port_table_size): Explicitly give type as 'int';
4945 don't rely on archaic C default type rules.
4947 * fports.h: #include "libguile/ports.h", since you need that in
4948 order to parse this.
4950 * genio.h: #include "libguile/print.h", because you need that to
4951 parse this; don't bother #including "ports.h", since print.h gets
4954 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
4956 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
4957 this; it's now a reference to an element of *scm_root.
4959 * debug.h: Don't #include "options.h"; the compiler won't be able
4960 to find that once the headers are installed; instead, #include
4961 "libguile/options.h".
4962 * gc.h: Same, with marksweep.h.
4963 * mbstrings.h: Same, with symbols.h.
4964 * scmhob.h: Same, with _scm.h.
4965 * smob.h: Same, with params.h.
4967 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
4968 C files; there's no need for this, and it forces recompilations
4971 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
4973 * error.c (scm_error): declare scm_error_callback.
4975 * error.h: prototype for scm_error_callback.
4977 * __scm.h: define lgh_error.
4978 (SCM_SYSERROR): redefine using lgh_error.
4980 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
4982 * error.c (scm_error): new procedure.
4984 * error.h: prototype for scm_error.
4986 * Makefile.in (install): install scmconfig.h from the current
4987 directory, not $(srcdir).
4989 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4991 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
4992 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
4993 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
4994 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
4995 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
4996 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
4997 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
4998 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
4999 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5000 vports.h, weaks.h: #include "libguile/__scm.h", not
5001 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
5002 dependencies are within libguile properly.
5004 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
5006 * Makefile.in (.c.x): Simplify; there's no need to run this rule
5007 when scmconfig.h doesn't exist.
5009 * load.c (scm_sys_try_load): Correct spelling.
5011 * feature.c (scm_loc_features): Make this static.
5013 * Makefile.in (libpath.h): Omit trailing slash from path. We
5014 shouldn't require it of users, so why put it here?
5016 Move code to initialize and search %load-path from ice-9 to C
5017 code, so we can use the load-path to find the ice-9 boot code;
5018 this makes it easier to run Guile without installing it. See
5019 corresponding changes in guile/Makefile.in.
5020 * feature.c: Move stuff concerned with the load path to load.c.
5021 (scm_compiled_library_path): Deleted.
5022 Don't #include libpath.h here.
5023 * feature.h: Don't mention scm_compiled_library_path.
5024 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
5025 <sys/stat.h>, and <unistd.h> (if present).
5026 (R_OK): #define if the system hasn't deigned to.
5027 (scm_loc_load_path): New variable.
5028 (scm_init_load_path, scm_sys_search_load_path,
5029 scm_sys_try_load_path): New functions.
5030 (scm_init_load): Initialize scm_loc_load_path to point to the
5031 value cell of the Scheme %load-path variable.
5032 * load.h: Add declarations for scm_sys_search_load_path,
5033 scm_sys_try_load_path.
5034 * init.c: Call scm_init_load_path.
5035 * Makefile.in (feature.o, load.o): Dependencies updated.
5037 * load.c, load.h: Rewrite using PROTO macro.
5039 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5041 * gc.c (scm_cellp): New function: C predicate to determine if an
5042 SCM value can be regarded as a pointer to a cell on the heap.
5044 * gc.h: Added declaration of scm_cellp.
5046 * gdb_interface.h: New file: The GDB interface header from the GDB
5049 * gdbint.c: New file: GDB interface.
5051 * gdbint.h: New file: GDB interface.
5053 * libguile.h: Added #include <libguile/gdbint.h>.
5055 * init.c (scm_boot_guile): Added scm_init_gdbint.
5057 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
5058 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
5059 found if object files and source are kept separate).
5061 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
5063 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
5065 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
5067 * configure.in: Don't substitute the values of TCL_SRC_DIR and
5068 TK_SRC_DIR; they're not relevant any more.
5070 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
5071 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
5073 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
5075 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
5076 search path, so we can find the <libguile/MUMBLE.h> headers.
5078 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
5080 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
5081 implicit in the .c.o rule.
5082 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5085 Put the library path in a header file, instead of passing it on
5086 the command line in every compilation.
5087 * Makefile.in (libpath.h): New target.
5088 (feature.o): Depend on libpath.h.
5089 (clean): Delete libpath.h.
5090 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5091 * feature.c: ... #include "libpath.h" here.
5092 * .cvsignore: Ignore libpath.h.
5094 Don't install the unwashed masses of Guile header files in the
5095 main #include path; put most of them in a subdirectory called
5096 'libguile'. This avoids naming conflicts between Guile header
5097 files and system header files (of which there were a few).
5098 * Makefile.in (pkgincludedir): Deleted.
5099 (innerincludedir): New variable; this and $(includedir) are enough.
5100 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5101 (installed_h_files): Divide this up. Now this variable lists
5102 those header files which should go into $(includedir) (i.e. appear
5103 directly in the #include path), and ...
5104 (inner_h_files): ... this new variable says which files appear in
5105 a subdirectory, and are referred to as <libguile/mumble.h>.
5106 (h_files): List them both.
5107 (install): Create innerincludedir, not pkgincludedir. Put
5108 the installed_h_files and inner_h_files in their proper places.
5109 (uninstall): Corresponding changes.
5110 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5111 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5112 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5113 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5114 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5115 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5116 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5117 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5118 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5119 vports.h, weaks.h: Find __scm.h in its new location.
5120 * __scm.h: Find scmconfig.h and tags.h in their new locations
5121 (they're both "inner" files).
5123 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5125 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5127 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5129 * posix.c: Doc fixes.
5131 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5133 * socket.c: Don't include a prototype for inet_aton; just use a
5134 K&R style declaration, to avoid warnings but minimize the chance
5135 of conflicts with the system.
5137 On NextStep, <utime.h> doesn't define struct utime, unless we
5138 #define _POSIX_SOURCE before #including it.
5139 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5140 * acconfig.h: New comment text for above CPP symbol.
5141 * configure.in: Call it.
5142 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5144 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5146 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5147 testing for __EMX__.
5149 * posix.c: #include <libc.h>, if it exists.
5151 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5152 don't even know if the latter exists.
5154 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5155 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5156 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5158 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5160 (scm_init_posix): Use them when initializing the Scheme constants
5163 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5165 * Makefile.in (libdir, includedir, bindir): Use the
5166 autoconf-supplied values, instead of deriving them ourselves.
5167 (pkgincludedir, datadir, pkgdatadir): New variables.
5168 (install, uninstall): Put the header files in a special
5169 subdirectory, not in the main search path.
5171 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5172 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5174 * Makefile.in (IMPLPATH): Deleted; never used.
5176 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5177 on the Tcl/Tk source any more.
5178 (INCLUDE_CFLAGS): Remove references to the above.
5180 * Makefile.in (version.o): Corrected dependencies.
5182 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5184 * libguile.h: #include "version.h"
5186 * init.c (scm_boot_guile): Call scm_init_version.
5187 * gscm.c (gscm_run_scm): Call scm_init_version.
5189 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5190 GUILE_VERSION): AC_DEFINE these.
5191 (acconfig.h): #undef the above symbols.
5193 * Makefile.in (libobjs): Add version.o.
5194 (installed_h_files): Add version.h.
5195 (c_files): Add version.c.
5196 (gen_c_files): Add version.x.
5197 (version.o): New rule.
5198 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5199 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

5208 weaks.o): Add version.h to dependency lists.
5209 (markers.o): Remove duplicate rule.
5211 * version.h: New file.
5213 * version.c: New file.
5215 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5217 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5218 array; use it appropriately. Since GCC is quite happy to
5219 subscript functions, it never warned us about this; we should use
5220 -Wpointer-arith in the future. I guess we never tested
5223 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5225 * socket.c: Doc and copyright fixes.
5227 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5229 * debug.c: Fixed and improved gdb support.
5231 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5233 * socket.c: Added declaration of inet_aton to avoid compiler
5234 warning. (Hope this solution is correct.)
5236 * stime.c: Added declaration of ftime. (This is missing in
5239 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5241 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5243 * Makefile.in (c_files): add strerror.c.
5245 * strerror.c: new file from Emacs' sysdep.c.
5246 maybe configure should also check for sys_errlist.
5248 * configure.in (AC_REPLACE_FUNCS): add strerror.
5250 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5252 * debug.c (scm_init_debug): Added initialization for
5253 scm_evaluator_traps.
5255 * debug.h, debug.c: Various name changes.
5256 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5257 "debug-options-interface". See commentary in options.c.
5259 * options.h, options.c: Options now have documentation strings.
5260 Also added a long explanatory commentary.
5262 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5265 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5266 last_debug_info_frame is now updated in all cases.
5268 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5271 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5273 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5274 Added option STACK_CHECKING.
5276 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5278 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5280 * __scm.h: Removed symbols for debugging support.
5282 * acconfig.h: Added symbols for debugging support.
5284 * configure.in: Added user option for debugging support.
5285 --enable-debug will include the debugging code into libguile.a.
5287 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5288 scm_relocate_chunk_to_heap.
5290 * debug.c: New file: low-level debugging support. It also
5291 includes support for debugging with gdb. (The extensions to gdb
5292 are written by Per Bothner at Cygnus.)
5294 * debug.h: New file: low-level debugging support.
5296 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5297 argument pairs. Extensive modifications to the debugging
5298 evaluator. Added "SECTION:" commentaries to clarify what happens
5299 when, during double compilation. Renamed EVALIMP --> EVALIM.
5300 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5301 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5302 the beginning of the file. New procedure: scm_unmemocopy.
5303 Added some global state variables needed by the debugging
5304 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5305 check_entry, check_apply, check_exit, debug_options and
5306 evaluator_traps. New acro: undefine.
5308 * eval.h: Renamed EVAL --> XEVAL.
5310 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5311 --> scm_make_weak_key_hash_table.
5313 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5314 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5316 * libguile.h: Conditionally include debug.h
5318 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5319 scm_object_properties shouldn't return handle. `handle' now gets
5320 initialized in scm_set_object_properties_x. scm_object_properties
5321 doesn't any longer create an entry in scm_object_whash.
5323 * options.c: New file: handling of run time options.
5325 * options.h: New file: handling of run time options.
5327 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5329 * print.c: New procedure: scm_print_options
5331 * print.h: Defines for print options.
5333 * read.c: New procedure: scm_read_options
5335 * read.h: Defines for reader options.
5337 * root.h: Added scm_source_whash among scm_sys_protects.
5339 * srcprop.c: New file: source properties.
5341 * srcprop.h: New file: source properties.
5343 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5344 (Bug found by A. Green.)
5346 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5348 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5350 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5352 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5354 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5355 and should be called by the final client.
5357 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5359 * gc.h: Use the PROTO macro when declaring functions.
5360 * gc.c: Use the PROTO macro when declaring static functions.
5361 Remove the CPP hair around function definitions.
5363 * gc.c (scm_init_storage): Initialize scm_asyncs.
5365 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5366 preprocessor symbol; "__scm.h" is where it might get #defined.
5367 * __scm.h: Similar: #include <scmconfig.h> before testing
5370 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5372 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5374 * init.c (scm_boot_guile): Add init_func argument; call
5375 (*init_func) instead of calling scm_appinit; it's ucky to
5376 hard-code names for the user's procedures.
5377 * init.h (scm_boot_guile): Adjust declaration.
5379 * __scm.h (PROTO): New macro, for declaring functions with
5382 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5383 eliminate all the __STDC__ conditionals.
5384 (scm_boot_guile): Add declaration.
5385 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5386 Remove __STDC__ conditionals around function definitions; the
5387 declarations in init.h will provide the same information, more
5390 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5391 complain about it in the error message; the error message is
5392 adequate without that note, and there's nothing the user can do
5395 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5397 * Makefile.in (ancillary): Drop def.sed.
5399 * posix.c (scm_init_posix): Use numeric values, rather than
5400 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5401 F_OK. The symbols aren't available on some systems, and I'm
5402 pretty sure their values are fixed by common widespread practice.
5403 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5405 More functions unavailable on some systems.
5406 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5407 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5409 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5410 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5411 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5412 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5413 stub that signals an error as the #else.
5415 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5417 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5419 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5421 * unif.c: include ramap.h.
5423 * read.c (endif): case_insensative_p renamed case_insensitive_p.
5425 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
5427 * ports.c: include sys/ioctl.h.
5429 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5431 * configure.in: check for sys/ioctl.h.
5433 * ports.c: include <malloc.h> not "malloc.h".
5435 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5437 * fports.c: remove ttyname and tmpnam declarations.
5439 * posix.c: fewer ttyname declarations.
5441 * fports.c: include <string.h> not "string.h".
5443 * init.c, ioext.c: include string.h and unistd.h.
5445 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5447 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5448 genio.c, simpos.c, vports.c: include string.h.
5450 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5452 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5454 (scm_addr_buffer_size): change type from scm_sizet to int.
5455 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5456 from scm_sizet to int.
5458 * error.c: include unistd.h.
5460 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5463 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5465 * __scm.hd, def.sed: deleted.
5467 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5469 Changes for NeXT, suggested by Robert Brown.
5470 * configure.in: Call AC_TYPE_MODE_T.
5471 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5472 NeXT. Put header file list in alphabetical order.
5473 * configure, scmconfig.h.in: Regenerated.
5474 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5476 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5479 * acconfig.h: New file, providing documentation for the CPP
5480 symbols defined in configure.in
5481 * acconfig-1.5.h: Removed; superceded by the above.
5483 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5485 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5487 * fports.c (scm_open_file): don't return #f, throw error.
5489 * ioext.c (fileno): renamed from %fileno.
5490 (soft-fileno): deleted.
5492 * ports.c (scm_port_revealed): don't need to check for -1 from
5494 (scm_set_port_revealed_x): return unspecified, not #f.
5496 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5498 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5500 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5502 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
5504 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5506 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5507 This is necessary on Ultrix, and doesn't hurt portability.
5509 * Makefile.in (dist-dir): New target, implementing a new dist system.
5510 (installed_h_files): Put in alphabetical order.
5511 Remove duplicate entries for markers.h and unif.h.
5512 (c_files): Remove duplicate entries for markers.c.
5513 (ancillary): Renamed from anillery; all uses changed. Remove
5514 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5515 Remove all the ../doc/* files; doc/Makefile.in handles that.
5517 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5519 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5520 every if must have an else, or else the whole command has a
5521 non-zero exit code whenever the if's condition is false.
5523 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
5525 * posix.c: include string.h.
5527 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
5529 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
5532 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
5533 Remove leading % from scheme names.
5534 Do not return error values, call SCM_SYSERROR or similar.
5536 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
5538 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
5540 * struct.c (scm_init_struct): new file.
5542 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
5544 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
5545 (scm_list_head): added list-head for rapidly chopping argument
5546 lists off of longer lists (and similar).
5548 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
5550 * objprop.c (scm_object_property): assq the cdr of the whash
5551 handle for obj, not the handle itself.
5553 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
5555 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
5556 weak hash tables last of all marking to avoid an obscure gc bug.
5557 WARNING: circular lists stored in a weak hash table will hose us.
5559 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
5561 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
5562 new functions similar to scm_substring_move_left_x and
5563 scm_substring_move_right_x.
5565 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
5567 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
5570 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
5572 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
5574 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
5576 * strports.c (scm_strprint_obj): convenience function. C for
5577 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
5579 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
5580 removed to a separate library
5582 * init.c (scm_boot_guile): copied from guile-tcl.c.
5583 Initialization specific to tcl interpreters removed.
5585 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
5587 * ports.c (scm_ports_prehistory): size malloced here doesn't
5588 matter so long as it is non-0 (got rid of "* 4").
5590 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
5592 * gscm.h: gscm_mkarray eliminated (presumably was not being used
5593 since its definition was bogus).
5595 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
5597 * mallocs.[ch]: back again (for rx at least).
5599 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
5601 * ports.c: removed functions relating to the mapping between ports
5602 and descriptors. (That stuff is unix-specific and should be collected
5603 in a separate library).
5605 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
5606 (Tom Mckay@avanticorp.com)
5608 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
5610 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
5611 handled correctly (SCM_FREEP was applied to them) -- test for
5612 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
5613 being overwritten with #f. (brown@grettir.bibliotech.com)
5615 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
5617 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
5618 for a specific symbol or for all symbols.
5620 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
5622 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
5623 keys and weak values confused).
5625 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
5627 * list.c (scm_last_pair): map '()=>'()
5629 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>

5632 Generalized assoc and hash-table functions.
5633 Factored pairs.c into multiple files.
5635 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
5637 * gscm.c (gscm_run_scm): got rid of objprop.
5639 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
5641 * genio.c (scm_getc):
5642 NOTE: fgetc may not be interruptable.
5644 * procprop.c (scm_stand_in_scm_proc):
5645 NOTE: don't use a alist here.
5646 (scm_set_procedure_properties_x): fix type checking throughout this file.
5648 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
5650 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
5651 after freeing part of the port table.
5653 Thu Feb 29 16:21:17 1996 Tom Lord <lord@beehive>
5655 * strports.c (scm_mkstrport):
5656 * vports.c (scm_make_soft_port): allocate a port table entry
5657 (possibly triggering gc) before setting the tag of the corresponding
5660 * pairs.c (scm_delq_x): never throw an error.
5662 * vectors.c (scm_make_vector): made the default vector fill argument
5663 into '() (much more useful than the previous value, "#unspecified")
5665 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
5667 * ports.c (scm_add_to_port_table): Added fields
5668 to port table entries: file_name, line_num, col.
5669 Update these in open_file, gen_getc and gen_ungetc.
5670 Added procedures to access those fields.
5672 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
5674 * procs.c (scm_make_subr_opt): new entry point for making
5677 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
5679 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
5681 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
5683 * numbers.c (scm_exact_p): This function no longer
5684 implements "integer?".
5686 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
5688 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
5689 (scm_gc_stats): return an assoc of useful data. Replaces "room"
5690 and the stats reporting formerlly built into repl.
5692 * repl.[ch]: removed.
5693 GC statistics keeping moved to gc.c.
5694 Other statistics keeping can be done from Scheme.
5695 REPLS are now written in Scheme.
5697 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
5699 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky
5700 conservatively marked objects).
5702 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
5704 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
5706 * feature.c (scm_compiled_library_path): moved here from repl.c.
5707 This file is for stuff relating specifically to Scheme libraries
5710 * eval.c (scm_m_define): don't give warning about redefinition, don't
5713 NOTE: this should throw a resumable exception with parameters --
5714 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
5716 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
5718 * error.c: scm_warn eliminated.
5720 * read.c (scm_lreadr): extra right paren gets an error, not a warning.

5723 lose exit_report, growth_mon.
5725 * gscm.c: got rid of verbosity functions.
5727 Tue Feb 20 00:19:10 1996 Tom Lord <lord@beehive>
5729 * throw.c (scm_ithrow): guard against the bad-throw hook changing
5730 between the call to procedurep and use.
5732 * error.c (scm_everr):
5734 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
5737 * strports.c: don't reveal the port's string to the caller
5738 because it changes size.
5740 (stputc stwrite): check/change the strings length with interrupts
5743 * objprop.c (scm_set_object_property_x &c): use the generic
5744 hashing functions and be threadsafe.
5746 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
5747 (per suggestion jaffer@gnu.ai.mit.edu).
5749 * mbstrings.c (scm_multi_byte_string): guard against argument list
5752 * strings.c (scm_make_string): loop cleanup
5754 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer
5757 * weaks.c (scm_weak_vector): guard against argument list
5760 * variable.c (scm_builtin_variable): check for/make a built-in
5763 * vectors.c (scm_vector): while filling the new array,
5764 guard against a list of fill elements that grows after
5765 the vector is allocated.
5767 * hashtab.c -- new file: general hash table
5768 functions. hash, hashq, hashv, hashx.
5770 * tags.h: made wvect an option bit of vector.
5772 Mon Feb 19 09:38:05 1996 Tom Lord <lord@beehive>
5774 * symbols.c: made the basic symbol table operations atomic.
5776 * root.c &c.: collected stack-specific global state.
5777 linum/colnum etc *should* be port-specific state.
5779 * struct.c (scm_init_struct): init the first struct type during
5780 initialization to fix a race condition.
5782 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
5783 object, not in a global.
5784 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
5786 * throw.c (_scm_throw): Pass throwval on the stack, not in a global
5787 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
5789 * *.[ch]: namespace cleanup. Changed all (nearly) exported CPP
5790 and C symbols to begin with SCM_ or scm_.
5792 Sun Feb 18 15:55:38 1996 Tom Lord <lord@beehive>
5794 * gsubr.c (scm_gsubr_apply): statically allocate the
5795 array of arguments (bothner@cygnus.com).
5797 Sat Feb 17 20:20:40 1996 Tom Lord <lord@beehive>
5799 * scmsigs.c: Simplified to use async rountines.
5801 * async.c: New support for interrupt handlers.
5803 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
5805 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
5806 set the multi_byte flag correctly in symbols. This is wrong.
5807 intern_obbary_soft and msymbolize should take an extra parameter.
5808 Also, weird multibyte symbols don't print correctly.
