1 1998-09-05 Jim Blandy <jimb@zwingli.cygnus.com>
3 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
4 signed/unsigned comparisons.
6 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
7 avoid signed/unsigned comparisons.
8 * smob.h (scm_numsmob): Change extern declaration to match.
10 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
11 avoid signed/unsigned comparisons.
12 * ports.h (scm_numptob): Change extern declaration to match.
13 (scm_current_load_port, scm_set_port_line_x,
14 scm_set_port_column_x): New prototypes.
16 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
17 test code, and it causes warnings.
19 * gh.h (gh_int2scmb, gh_uniform_vector_length,
20 gh_uniform_vector_ref): Added prototypes.
22 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
23 debugging support unconditionally. That's backtrace.c, stack.c,
24 debug.c, and srcprop.c.
25 (EXTRA_libguile_la_SOURCES): Omit those from here.
26 * Makefile.in: Regenerated.
28 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
30 * options.c (scm_options): Bugfix: Allow empty list of options!
32 * debug.c, debug.h (scm_single_step): Removed.
33 (scm_with_traps): New procedure. This procedure could easily be
34 written in Scheme but needs to be highly optimized.
36 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
38 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
39 Check SCM_TRAPS_P before trapping.
41 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
43 Changes to avoid signed/unsigned comparison warnings.
44 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
45 (scm_gc_sweep): Make n and j local to the blocks they're used in,
46 so they can have appropriate types for each application. Make i
47 signed. Use initializers in some spots. I'll probably pay for
49 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
50 (scm_must_realloc): Make nm unsigned.
51 (init_heap_seg): Make new_seg_index and n_new_objects signed.
52 (scm_init_storage): Use prototype-style definition, and make the
54 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
55 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
57 * filesys.c (scm_readlink): Make local vars rv and size ints, to
58 avoid signed/unsigned comparison warnings, and because the return
59 value of readlink may be -1. Don't bother casting the third
62 * filesys.c (scm_dirname, scm_basename): Move these to their own
63 page, at the end of the file.
64 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
66 * eval.h (scm_eval_options_interface): Add external prototype for this.
67 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
69 * eval.c (scm_lookupcar1): Make this static.
71 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
72 Make these prototype declarations, not K&R-style.
74 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
75 unsigned comparison warning.
77 * appinit.c: File removed. It had a single function in it, empty,
78 whose reason for existence is explained in no documentation or
79 comment. I think it's there as a default for some Tcl-style
80 initialization, but Tcl abandoned that approach a while ago.
81 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
82 (BUILT_SOURCES): Remove appinit.x.
83 * Makefile.in: Regenerated.
85 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
87 * Makefile.in: Regenerated using the last public version of
88 automake, not the hacked Cygnus version.
90 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
93 * Makefile.in, scmconfig.h.in: Regenerated.
94 * init.c, readline.c: Don't check if TOTORO is #defined.
96 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
98 * Makefile.am: Adjust for new thread configuration system.
99 (INCLUDES): Include the value of THREAD_CPPFLAGS.
100 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
102 (THREAD_LIBS): Definition deleted; automake will generate such
103 things automatically.
104 * Makefile.in: Regenerated.
106 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
108 Simplify smob and port marking; set the mark bit in the generic
109 marking code, and make marker routines only responsible for
110 turning up outgoing pointers.
111 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
112 before calling the marking function. Don't call the marking
113 function if it's zero.
114 * markers.c (scm_mark0): Just return #f. This function isn't
115 necessary at all now, but it's harmless to call it. We'll leave
116 it in so other folks' code doesn't croak at link time.
117 (scm_markcdr): Don't call SCM_SETGC8MARK.
118 * async.c (mark_async): Don't call SCM_SETGC8MARK.
119 * dynl.c (mark_dynl_obj): Same.
120 * root.c (mark_root): Same.
121 * srcprop.c (marksrcprops): Same.
122 * unif.c (markra): Same.
123 * variable.c (scm_markvar): Same.
124 * ports.c (scm_markstream): Same.
125 (void_port_ptob): Specify zero for our marking function.
126 * debug.c (debugobjsmob): Same.
127 * dynwind.c (guardsmob): Same.
128 * filesys.c (dir_smob): Same.
129 * fluids.c (fluid_smob): Same.
130 * fports.c (scm_fptob, scm_pipob): Same.
131 * mallocs.c (mallocsmob): Same.
132 * regex-posix.c (regex_t_smob): Same.
133 * smob.c (freecell, flob, bigob): Same.
134 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
135 * throw.c (jbsmob, lazy_catch_funs): Same.
137 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
139 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
140 scm_copy_tree on code in order not to let memoized code to leak
141 out. Thus, scm_copy_tree needs to copy vectors as well since
142 quasiquote can introduce evaluated code also inside vector
145 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
147 * eval.c (scm_copy_tree): Removed ability to copy vectors.
149 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
150 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
153 * unif.c: Say that ivect and uvect are of type signed and unsigned
154 long instead of int in commentary so that it correctly describes
157 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
159 * stime.c: Removed declaration of strptime. (It should be
160 declared by the system headers. If it turns out that some systems
161 don't, we'll handle that then.) (Thanks to Greg Troxel.)
163 * stime.h: Renamed TIMEH --> STIMEH
165 * backtrace.c (scm_display_error, scm_display_backtrace): In order
166 to increase portability, don't use structure assignment.
167 (Thanks to Nicolas Neuss.)
169 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
171 (finalize_fd_sets): Added empty statement after last case label.
172 (Thanks to Nicolas Neuss.)
174 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
177 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
179 * init.c, readline.c: OK, I won't have these readline.x bug
180 reports anymore. We've had them since April. The current reason
181 is a completely unintelligible failure of totoro.red-bean.com to
182 do the test for rl_getc_function in libreadline correctly. This
183 kludge overrides the test if we're on totoro so that the snapshot
184 generation process can work.
186 * readline.c: Define a strdup replacement if not existent on system.
188 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
190 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
191 This change makes scm_make_vector R5RS compatible. We cannot keep
192 the third argument since people want to be able to deduce the form
193 of the C function call only by looking at R5RS. (At the same time
194 we have removed some unnecessary complexity!)
196 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
197 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
198 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
199 argument in call to scm_make_vector.
201 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
203 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
204 This macro is useful in applications.
206 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
208 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
209 (scm_parse_path, scm_search_path): New Scheme level procedures.
211 * load.h (scm_internal_parse_path, scm_parse_path,
212 scm_search_path): Declared.
214 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
216 * filesys.c (dirname, basename): New procedures.
218 * init.c (scm_boot_guile_1): Removed condition around
221 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
222 new data type (guards) for representation of C level guards and
223 data on the wind chain.
224 (scm_internal_dynamic_wind): New function.
226 * dynwind.h: Declare scm_internal_dynamic_wind.
228 * root.h (scm_root_state): Added scm_cur_loadp.
230 * root.c (mark_root): Added comment about cur_loadp.
232 * load.c: #include "dynwind.h";
233 (scm_primitive_load): Use scm_inner_dynamic_wind to update
236 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
238 * ports.c (current-load-port): New procedure.
240 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
242 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
243 not a tty, return #f.
245 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
246 to Julian Satchell and Roland Kaufmann.)
248 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
249 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
251 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
253 * debug.h, debug.c (scm_start_stack): New function. Implements
254 the guts of old scm_m_start_stack.
256 * debug.c (scm_m_start_stack): Use scm_start_stack.
258 * init.c (scm_start_stack, scm_restart_stack): Renamed to
259 start_stack and restart_stack. (These have static scope.)
261 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
263 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
264 readline functions to come in release 2.3. (Thanks to Chet
266 (handle_errors): Use the above functions.
268 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
270 * readline.c: Improvements for readline support: Handle errors
271 better; Implement before-read-hook.
273 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
275 * init.c (scm_boot_guile_1), readline.c: Test for
276 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
277 assure that we have version >= 2.1.)
279 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
281 * readline.c (scm_add_history): Bugfix: Do strdup before giving
282 away the string to add_history.
283 (completion_function): Do completion for readline. (Thanks to
285 (scm_filename_completion_function): New procedure: Filename
287 (current_input_getc): New function. Use this one instead of
288 standard getc from readline.
290 * throw.c, throw.h (scm_handle_by_throw): New function: This
291 handler throws errors to next handler on the dynwind chain.
293 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
295 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
298 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
300 * procprop.c (scm_i_procedure_arity): New function. Returns arity
302 (scm_procedure_properties): Modified to return arity together with
304 (scm_procedure_property): Added the read-only property `arity'.
305 (scm_set_procedure_property_x): It is an error to set the `arity'
308 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
309 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
311 * procprop.h (scm_sym_arity): New symbol.
313 * objects.c (scm_set_object_procedure_x): New procedure: Use this
314 to set the dispatch procedure of an operator or entity object.
316 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
317 Made procedure slots read-only.
319 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
320 scm_tcs_cons_gloc case in zero args switch; Fixed args
321 construction for operators in scm_tcs_cons_gloc case in two args
324 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
326 * fluids.c: Removed use of assert.h (in order to avoid
329 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
331 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
333 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
334 change makes the evaluator safer at the cost of evaluation speed.
335 It handles the case when the user has added a non-immediate
336 improper end of the application form, e.g., `(+ 0 . x)'.
337 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
338 minimize the extra cost as much as possible. The new code is
339 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
340 problem with structs planted directly in the code (e.g. by a
341 macro). This no longer causes segmentation fault. (Thanks to
344 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
345 arg `proc' in order to be able to throw errors; New argument
348 * Removed extra #include "debug.h"
350 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
352 * scmsigs.c: Declare usleep as returning void on some systems.
353 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
356 * coop.c (usleep): Return void on some systems.
358 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
360 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
362 * coop.c: Changed return type of usleep to int.
364 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
365 isn't found in the OS.
367 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
368 isn't enabled. (Thought that I had made this change ages ago...)
370 * iselect.c: Declare bzero if not defined by OS.
372 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
374 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
375 condition. (Thanks to John Tobey.)
377 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
378 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
381 * __scm.h: Start the long-term project of moving to POSIX threads.
382 Phase 1: Classification of all critical sections.
383 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
384 for A sections. (See comments in __scm.h for details.)
386 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
387 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
389 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
391 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
392 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
393 (libpath.h, versiondat.h): Replaced dependency on Makefile with
394 dependencies on $(srcdir)/Makefile.in
395 $(top_builddir)/config.status in order to avoid circularity.
397 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
398 from argc if argc was 0 initially.
400 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
401 in generation of libpath.h.
403 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
405 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
406 libguile from 2 to 3.
408 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
410 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
412 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
414 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
415 scm_set_port_column_x, scm_port_filename,
416 scm_set_port_filename_x): Removed optional arguments. Added
417 proper argument checking.
419 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
420 stack size in machine words.
422 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
423 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
424 to Ole Myren Röhne.)
426 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
428 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
429 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
431 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
434 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
435 procedure apply: Copy argument lists before pushing them unto the
436 environment so that the environment won't get mutated due to
437 manipulation of procedure arguments. This should perhaps be
438 regarded as a temporary solution until someone finds a more
439 efficient one. (Thanks to Maciej Stachowiak.)
441 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
443 * script.c (scm_compile_shell_switches): Use "guile" as default
444 zero arg if argc is NULL.
446 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
448 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
449 is zero. (Thanks to Dirk Herrmann.)
451 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
453 * ports.c (scm_add_to_port_table): First line is now line 0
454 (was 1). (Interface changed according to suggestion by Per
457 * backtrace.c (display_header): Add 1 to line and column numbers
458 when presenting them to the user.
460 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
461 from debug.c --> eval.c
463 * eval.h, eval.c (scm_eval_options_interface): New options
465 (SCM_EVAL_STACK): New option: Size of newly created stacks,
466 i.e. stacks for new threads.
468 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
470 * eval.c (unsafe_setjmp): Removed with #if 0.
472 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
475 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
476 to avoid compiler warnings.
478 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
480 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
482 * throw.c (handler_message): Print message on current error port
483 instead of default error port. (Thanks to Maciej Stachowiak.)
485 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
487 * ports.c (scm_add_to_port_table): allocate in units of
488 struct scm_port_table *, not struct scm_port_table.
489 * posix.c (scm_close_pipe): remove the port from the port table
491 Thanks to Rob Engle for both fixes.
493 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
495 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
496 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
498 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
500 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
502 * backtrace.c (display_error_body, display_backtrace_body),
503 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
504 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
505 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
506 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
509 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
510 don't receive the jmpbuf arg anylonger.
511 (scm_catch): Don't accept a #f tag.
512 (scm_throw): Check that key is a symbol.
513 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
515 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
517 * async.c (async_pending): Removed declaration.
519 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
521 * dynwind.c (scm_wind_chain): New debug function.
523 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
524 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
525 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
526 extra layer of functions around the body and handler of a thread.
527 This extra layer makes sure that the handler is called in the
528 dynamic context of the surround (= empty dynwind list), but under
529 the *dynamic root* of the body. We can not use the dynamic root
530 of the surround since that root belongs to another thread => stack
531 is not handled correctly. It may seem ugly to use this extra
532 layer, but the extra cost in terms of execution time is really
533 negligible compared to the total amount of time required to create
534 a thread, and it would reduce maintainability to duplicate the
535 crucial and complicated steps performed by cwdr.
537 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
538 (SCM_ALLOW_INTS): Added thread switching code before interrupts
539 get re-enabled. The important effect of this is that interrupts
540 are blocked during thread switching so that thread data structures
541 don't risk getting messed up by an unfortunate signal.
542 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
543 seems to do more aggressive optimization which actually move
544 instructions around in these macros in a fatal way. Therefore:
545 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
546 just superstitious...)
547 (SCM_TICK): Maybe do a context switch and take care of asyncs.
548 This macro should be used instead of SCM_ASYNC_TICK since the
549 latter doesn't do context switches any more.
551 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
552 instead of SCM_ASYNC_TICK.
554 * coop.c, iselect.c: Since thread switches are now performed with
555 interrupts masked, we can't use the old mechanism of delivering
556 signals immediately when they arrive. Signals must instead be
557 delivered when the asyncs run *after* the end of the critical
558 section in scm_internal_select. But this also means after context
559 switch so that the signal will be delivered to a different thread.
560 To avoid this, I have changed the protocol of
561 coop_wait_for_runnable_thread and friends so that they are allowed
562 to return the original thread. So, if a signal arrives during
563 scm_internal_select, we won't any longer be forced do a context
564 switch, but can remain in the same thread and deliver the signal
567 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
568 scm_asyncs_pending and made it global.
570 * iselect.c: Small fixes.
572 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
573 coop_condition_variable_init, coop_condition_variable_wait,
574 coop_condition_variable_signal): Changed return type from `void'
575 to `int'. This is to adhere closer to the pthreads interface.
576 This, in turn, is part of an attempt to provide C versions of the
577 mutex and condition variable primitives which can be part of a
578 frontend to COOP or pthreads.
580 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
581 coop_condition_variable_destroy): New functions.
583 * coop-threads.c (scm_wait_condition_variable): Use
584 coop_condition_variable_wait_mutex.
586 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
587 Definitions moved to coop-defs.h.
589 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
590 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
591 scm_cond_destroy): New C interface to mutecis and cond vars.
593 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
595 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
597 * iselect.c: Now several threads can wait on the same file
598 descriptor. The behaviour is compatible with OS select: All
599 threads waiting for the fd return with the same status.
601 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
603 * coop-threads.c, threads.h (scm_spawn_thread): New function.
604 Can spawn a thread from application C code.
606 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
608 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
609 gh_doubles2scm): New functions.
611 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
613 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
614 commented-out version of gh_eval_str()
616 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
618 * socket.c (scm_bind): free soka after use.
620 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
622 * stime.c (tzvar): new variable.
623 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
624 avoid memory leaks when allocating.
626 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
628 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
631 * gc.c, tags.h: Doc fixes.
633 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
635 * eval.c (macro-eval!): Removed. This function was a design bug.
636 It allowed memoized code to leak out to the scheme level. Most
637 things that you could do with `macro-eval!' can be done with
640 1997-12-20 Tim Pierce <twp@skepsis.com>
642 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
643 scm_fgets now depends on ftell(3) to know how many bytes were
646 1997-12-15 Tim Pierce <twp@skepsis.com>
648 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
649 dealing with strings.
651 1997-12-13 Tim Pierce <twp@skepsis.com>
653 Make %read-line more suitable for implementing read-line efficiently.
654 * ioext.c (scm_read_line): Strip the terminating newline from a
655 string, and return a cons of the string and its terminator.
657 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
658 of the string that is read is stored in this memory location.
659 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
660 * genio.c, genio.h (scm_do_read_line): Update caller.
661 * ports.h (scm_ptobfuns): Update typedef.
662 * fports.c (scm_fptob, scm_pipob): Update struct.
664 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
666 * filesys.c (set_element): Return file descriptor.
667 (fill_select_type): Return the highest file descriptor.
668 (scm_select): Tell select about the highest file descriptor. On
669 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
670 Therefore the extra overhead for calculating the maximum fd seems
671 to be more than compensated. Is this correct? In any case,
672 scm_internal_select will be much faster with this info.
673 (scm_select, fill_select_type, set_element): Don't accept any kind
674 of object in the file descriptor list or vector.
676 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
678 * iselect.c (finalize_fd_sets): Bugfix.
680 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
682 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
683 when using scm_internal_select (since we might switch to another
686 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
688 * simpos.c (scm_system): always define: use sysmissing if not
689 available. Check for HAVE_SYSTEM instead of _Windows (does
690 Windows lack system or does it have an unusable one?).
691 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
692 Let the argument be optional: if not supplied, call system(NULL).
694 * ports.c (scm_close_port): relax the type check from OPPORTP to
695 PORTP; closing a closed port is allowed.
697 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
699 * fports.c (scm_fgets): Return if the last char in a chunk is
700 newline. When fgets returns a string whose length is `size-1', it
701 is ambiguous whether a whole line was retrieved, so we must check
702 explicitly whether a line terminator is present.
704 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
706 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
707 before taking the CDR. (Thanks to Harald Meland.)
709 * filesys.c (scm_stat): Slightly optimized.
711 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
713 * ports.c (scm_close_port): Make sure the port is open before
716 * guile-snarf.in: Pass args through to gcc in a way that preserves
717 whitespace boundaries. (Thanks to Greg Badros.)
719 1997-12-02 Tim Pierce <twp@skepsis.com>
721 * stacks.c (scm_frame_procedure): Reverse the logic in the return
722 statement. (Thanks to Doug Evans for pointing this out.)
724 1997-12-01 Tim Pierce <twp@skepsis.com>
726 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
728 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
730 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
731 errno macro expansion of this field name. (errno is a C
732 preprocessor macro on some systems.)
734 1997-11-29 Tim Pierce <twp@skepsis.com>
736 * iselect.c: Doc fix.
738 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
740 * init.c (scm_start_stack): Removed initialization of
741 scm_the_last_stack_var.
743 * backtrace.h: Declare scm_the_last_stack_var.
745 * backtrace.c: Define scm_the_last_stack_var.
747 * root.c (mark_root): Don't mark the_last_stack_var.
749 * root.h (scm_root_state): Removed the_last_stack_var.
751 * throw.c: Added #include "fluids.h"
752 (ss_handler): `the-last-stack' is now a fluid.
754 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
755 --> the_last_stack_fluid.
757 * backtrace.c: Added #include "fluids.h"
758 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
759 (scm_backtrace): `the-last-stack' is now a fluid.
761 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
762 after scm_init_fluids.
764 1997-11-28 Tim Pierce <twp@skepsis.com>
766 * iselect.c: #ifdef USE_THREADS around thread-related includes.
768 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
769 DLSYM_ADDS_USCORE to decide whether to add an underscore.
771 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
773 * iselect.c (coop_next_runnable_thread,
774 coop_wait_for_runnable_thread): Disable interrupts so that no
775 async is executed before a potential error_revive.
776 (scm_internal_select): Disable interrupts during the parts of the
777 code which manipulate the sleep queue and the file descriptors.
779 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
781 * Makefile.am: Added iselect.c and iselect.h.
783 * coop.c (coop_qinit): Initialize fields used by
785 (coop_qget, coop_qget, coop_tmp_queue): Made global.
786 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
787 replacement in iselect.c.
788 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
789 coop_join): If GUILE_ISELECT enabled, use
790 coop_wait_for_runnable_thread instead of
791 coop_next_runnable_thread.
792 (usleep, sleep): New replacements for system functions if
793 GUILE_ISELECT is enabled.
795 * coop-threads.h: Declare coop_wait_for_runnable_thread.
797 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
799 * filesys.c: Added #include "iselect.h". Moved FD-macros to
800 iselect.h. Implement Scheme level `select' using
801 scm_internal_select. (See NEWS.)
803 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
805 * init.c: Call scm_init_iselect.
807 * iselect.h, iselect.c: New files. Implements
808 scm_internal_select. (See NEWS.)
810 1997-11-27 Tim Pierce <twp@skepsis.com>
812 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
813 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
814 and scm_must_free, since ultimately the string returned will be copied
815 by scm_makfrom0str anyway. Also, read any characters that may have
816 been pushed onto the port with scm_ungetc.
817 * ports.c (scm_generic_fgets): Same as for scm_fgets.
818 * ioext.c (scm_read_line): Free string after Guilifying it.
819 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
821 1997-11-26 Anthony Green <green@hoser.cygnus.com>
823 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
825 * gh.h: Safely wrap prototypes for c++ usage.
827 1997-11-25 Mark Galassi <rosalia@cygnus.com>
829 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
830 gh_repl (argc, argv).
832 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
834 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
835 and to invoke scm_shell().
836 (gh_launch_pad): took out the loading of boot-9.scm from here,
837 since it is probably best to let the user control that. In fact,
838 gh_repl() now invokes scm_shell() which does that.
840 1997-11-23 Mark Galassi <rosalia@cygnus.com>
842 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
845 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
847 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
848 yesterday's underscore patch. (Thanks to Marius Vollmer for
851 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
853 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
854 DLSYM_ADDS_USCORE is not defined.
856 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
858 * gh_data.c (gh_uniform_vector_length):
859 (gh_uniform_vector_ref): started implementing the uniform types in
862 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
864 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
865 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
867 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
869 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
870 configure.in was changed).
872 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
874 * Makefile.am (modinclude_HEADERS): Include readline.h here.

877 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
879 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
880 OPORT is an `open' port, not an output port.
882 * filesys.c (scm_close, set_element, get_element, scm_chown,
883 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
884 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
885 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
886 scm_close_port, scm_port_line, scm_set_port_line_x,

888 scm_set_port_filename_x, scm_port_mode,
889 scm_close_all_ports_except, scm_set_current_output_port,
890 scm_set_current_error_port): Likewise
891 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
892 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
894 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
895 * backtrace.c (display_backtrace_body): Likewise
896 * fports (scm_setvbuf): Likewise
897 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
898 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
899 scm_getpeername, scm_send, scm_sendto): Likewise
900 * unif.c (scm_uniform_array_write): Likewise
902 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
904 Minor problems with substring-related tag changes.
905 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
906 exactly what we want to leave in to detect substrings.
907 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
908 * tags.h: Fix diagrams and comments describing the S tag bit;
909 remove vestigial remarks about the D tag bit.
910 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
911 * strings.c: Formatting tweaks.
913 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
914 variable first; then SCHEME_LOAD_PATH, with a warning message.
915 (scm_parse_path): New function.
916 * script.c: Doc fixes.
918 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
920 Readline support, from Daniel Risacher.
921 * readline.c, readline.h: New files.
922 * init.c: #include "readline.h".
923 (scm_boot_guile_1): Call scm_init_readline, if we have it.
924 * Makefile.am (libguile_la_SOURCES): Include readline.c.
925 * Makefile.in: Regenerated.
926 * scmconfig.h.in: Regenerated, after change to ../configure.
928 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>

932 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
934 * gh_data.c (gh_vector_set_x): changed name to make it consistent
935 with the ! -> _x mapping when going from Scheme to C.
937 1997-10-19 Mark Galassi <rosalia@cygnus.com>
947 (gh_assoc): added these gh_ functions implemented as macros.
949 * gh_predicates.c (gh_null_p):
950 (gh_string_equal_p): added these two missing predicates.
952 * gh_list.c (gh_append):
957 (gh_set_cdr_x): added these routines as I go through and try to
958 complete the picture R4RS functions that should be mirrored in the
961 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
963 * tags.h (scm_tc7_substring): Changed the comment and code to
964 conform with the changes below. Folks! We have suddenly two new
965 free tc7 codes!!! Jummy, jummy!
967 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
969 * Makefile.in: Rebuilt.
970 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,

983 * gscm.c (gscm_run_scm): Don't init mbstrings module.
984 * gc.c (scm_gc_mark): Don't handle mbstrings.
985 (scm_gc_sweep): Likewise.
986 * eval.c (SCM_CEVAL): Don't handle mbstrings.
987 * eq.c (scm_equal_p): Use SCM_TYP7S, not SCM_TYP7SD.
988 * tags.h (SCM_TYP7SD): Removed.
989 (SCM_TYP7D): Removed.
990 (scm_tc7_mb_string): Removed.
991 (scm_tc7_mb_substring): Removed.
992 * print.c (scm_iprin1): Handle char printing directly. Don't
994 Don't include "mbstrings.h".
995 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
996 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
998 Don't include "mbstrings.h".
999 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
1000 (SCM_SYMBOL_SLOTS): Define as 4.
1001 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.

1004 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
1005 struct.c, threads.c, throw.c, unif.c, variable.c: Use new
1006 ("gen"-less) I/O function names.
1007 * ports.c (scm_add_to_port_table): Don't set port's
1009 * ports.h (scm_port_representation_type): Removed.
1010 (scm_string_representation_type): Removed.
1011 (struct scm_port_table ): Removed representation field.
1012 (SCM_PORT_REPRESENTATION): Removed.
1013 (SCM_SET_PORT_REPRESENTATION): Removed.

1025 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1027 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1029 * gh_test_c.c (c_vector_test): some improvements on the vector
1032 * gh.h (gh_vector): this used to exist but do the wrong thing.
1033 Now it (almost) does the right thing, though it takes a list
1034 instead of the individual arguments. I need to see how it could
1036 (gh_list_to_vector): added this function as a macro. Corresponds
1037 to Scheme's (list->vector ...).
1038 (gh_vector_to_list): added this function as a macro. Corresponds
1039 to Scheme's (vector->list ...).
1041 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1042 gh_vector_ref, so that it resembles the Scheme routines more.
1043 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1044 resembles the Scheme routines more.
1045 (gh_make_vector): this used to be (stupidly) called gh_vector().
1046 This is the right name, since it does the same thing as the Scheme
1047 (make-vector ...) procedure.
1049 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1051 * ports.h: #include "libguile/print.h"
1053 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
1054 Some indentation fixes.
1056 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
1057 longer a user field; New field: class_flags.
1059 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
1061 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
1063 * gh_data.c (gh_bool2scm): new function which replaces
1064 gh_int2scmb(), which is now tagged as obsolete.
1066 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1068 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1069 macros should by convention not test for NIMPness.)
1070 (SCM_COERCE_OPORT): Adjust indentation.
1072 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1073 SCM_NIMP test before SCM_PRINT_STATE_P.
1075 * struct.c, struct.h, gc.c: Renamed:
1076 scm_struct_i_layout --> scm_vtable_index_layout
1077 scm_struct_i_vcell --> scm_vtable_index_vcell
1078 scm_struct_i_vtable --> scm_vtable_index_vtable
1079 scm_struct_i_printer --> scm_vtable_index_printer
1080 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1082 * struct.c (scm_print_struct): Use new printer slot; Default
1083 printing: Also output hex code of vtable so that type identity
1084 will be indicated as well.
1085 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1086 Removed struct_printer_var; Removed struct-vtable-offset;
1087 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1088 vtable-offset-user): New constants.
1090 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1091 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1092 If this slot contains a procedure, use that to print structures of
1093 the type represented by this vtable.
1095 * print.c (scm_iprin1): Don't print arguments of macro
1096 transformers. (They are always: exp env.); Bugfix: Unmemoize
1097 transformer source with correct environment.
1099 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1101 Streamlining of call-with-dynamic-root:
1103 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1104 there is now only one catch.
1105 (cwdr_outer_body): Removed.
1106 (cwdr_handler): New function.
1107 (scm_internal_cwdr): New function to perform the function of cwdr
1108 but take args that are more useful to C code. Also, the handler
1109 is now invoked *outside* of the new dynamic root, like the docs
1110 say. We no longer have to catch absolutely all errors, the caller
1111 is responsible for using a handler that does not throw, if he
1113 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1114 * root.h (scm_internal_cwdr): New prototype.
1116 Even more but risky streamlining:
1118 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1119 allocation of the jumpbuf of a root continuation. The changes
1120 below are controlled by it. They are now deactivated.
1121 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1122 the JMPBUF of the scm_rootcont to NULL before returning.
1124 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1125 when they are non-NULL.
1126 (scm_gc_mark): Likewise, mark only when non-NULL.
1128 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1129 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1131 * gc.c (scm_done_malloc): New function.
1132 gc.h (scm_done_malloc): New prototype.
1134 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
1135 (struct scm_print_state) [revealed]: New field.
1136 (scm_print_state_vtable): Make visible to the outside world for
1137 type checking purposes.
1138 (scm_valid_oport_value_p): New prototype.
1140 * print.c (scm_valid_oport_value_p): New function to check whether
1141 a certain value is acceptable as a port argument.
1142 (scm_print_state_vtable): New variable.
1143 (scm_free_print_state): Set `revealed' field to false.
1144 (scm_iprin1): Call user supplied closure printer with
1145 scm_printer_apply. Print in the traditional way when there isn't
1146 one or when it returns #f.
1147 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1148 Accept a port/print-state pair in addition to just a port.
1149 (scm_prin1): Don't return the print_state to the pool when it has
1151 (scm_printer_apply): Set `revealed' field of print_state to true.
1152 (scm_init_print): Set scm_print_state_vtable.
1153 (print_state_fluid, print_state_fluid_num): Removed.
1155 * throw.h (scm_handle_by_proc_catching_all): New prototype
1156 throw.c (scm_handle_by_proc_catching_all): New function
1158 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1160 * Makefile.in: Regenerated with automake 1.2c.
1162 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1164 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1165 was looping endlessly.
1167 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1169 * strports.c (scm_eval_string): Don't close the port.
1171 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1172 former returns a nice normal integer. (Thanks to Daniel
1175 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1177 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1178 makefile variable as a build parameter called LIBS. The
1179 build-guile program will use this, for the time being.
1180 * Makefile.in: Regenerated.
1182 Thanks to Shiro Kawai:
1183 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1184 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1187 * Makefile.in: Regenerated with automake 1.2a.
1189 * script.c (scm_compile_shell_switches): If we hit the -c or --
1190 arguments, don't set the car of (command-line) to scm_usage_name,
1191 the prettified name of the guile executable; give it the full
1192 path, the way shells usually handle $0.
1194 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1196 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1197 Scheme-level name `array-map' and renamed `serial-array-map' to
1198 `serial-array-map!'.
1200 * backtrace.c: Introduced exception handlers which now enclose
1201 `display-error' and `display-backtrace' so that error reporting
1202 won't get into infinite loops if an error occurs during displaying
1203 of the error. This can very easily happen with user supplied
1204 print call-back routines.
1206 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1208 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1209 the names `serial-array-map' and `array-map' should be removed.)
1211 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1213 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1214 Added #include "objects.h"
1216 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1217 Add #include "feature.h".
1219 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1220 (modinclude_HEADERS): Added objects.h.
1222 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1223 This test is needed at many places in the code and should be
1224 abstracted. (Motivated by the need of this test in libguiletk.)
1226 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1227 (scm_eval_string), load.c (scm_primitive_load,
1228 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1229 Use SCM_EOF_OBJECT_P.
1231 * eval.c (scm_init_eval): Add feature `delay'.
1233 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1235 * scmhob.h: Removed.
1237 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1239 * list.h (SCM_LISTn): New macros. Make list creation in C code
1240 prettier. The idea comes from STk.
1242 * sequences.h, sequences.c, append.h, append.c: Removed. These
1243 files implemented non-R4RS operations which would encourage
1244 non-portable programming style and less easy-to-read code.
1246 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1249 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1250 sequences.h, #include append.h.
1252 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1255 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1257 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1259 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1261 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1263 * eval.c: Added #include "objects.h"
1265 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1268 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1269 adjacent smob numbers.
1271 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1273 * procprop.h: Added declaration of scm_i_inner_name.
1275 * gsubr.c: New global symbol scm_i_inner_name.
1277 * debug.c (scm_procedure_name): Try procedure property
1278 `inner-name' if `name' fails.
1280 * print.c (scm_iprin1): Use scm_macro_name.
1282 * eval.c (scm_m_define): Give names to macros as well; Only the
1283 first top-level definition gives a procedure/macro a name.
1284 Otherwise confusing names can turn up in backtraces.
1285 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1286 `name'; Give names to macros as well.
1288 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1289 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1292 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1294 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1296 (prinmacro): Removed. The code has been moved/merged into print.c
1297 in order to decrease code redundancy. We want macros to print in
1298 a way equivalent to procedures, and it would be silly to duplicate
1299 the required code. (We don't want to maintain two places.)
1300 (macrosmob): Print field is now a NULL pointer.
1302 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1303 scm_macro_transformer): New prototypes.
1304 (scm_tc16_macro): Declared.
1306 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1307 are now printed in a way equivalent to procedures.
1309 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1311 * procs.h (scm_closure_p): Added declaration.
1313 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1315 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1316 Shouldn't pass "heap" as the subr name.
1318 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1320 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1321 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1322 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1323 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1324 SCM_BOOL_T. Any non-false value is true.
1326 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1328 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1329 scm_gensym): Added prototypes.
1331 * symbols.c (scm_gensym): New function. This will speed up
1332 certain types of applications (such as macro systems) which
1333 generate lots of symbols.
1335 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1337 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1339 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1341 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1342 specifier, since (2) or (2 . 3) would cause SEGV.
1343 (scm_transpose_array): more argument checking fixes.
1345 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1347 * Makefile.in: Regenerated.
1349 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1351 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1353 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1355 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1357 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1359 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1360 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1363 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1364 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1365 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1366 scm_array_p, scm_array_rank, scm_array_dimensions,
1367 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1368 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1369 scm_array_prototype): Added case scm_tc7_wvect.
1371 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1373 * errno.h: prototype for scm_strerror.
1374 * error.c (scm_strerror): new procedure.
1376 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1378 * list.c (scm_list_append_x): Allow non-pair as last argument.
1379 This is consistent with the R4RS append and is probably the
1380 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1382 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1384 * stime.h: prototype for scm_times.
1385 * stime.c (scm_times): new procedure.
1386 * ioext.c (scm_fseek): if the first argument is a file descriptor
1388 (scm_ftell): if the first argument is a file descriptor call lseek
1390 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1391 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1393 (scm_chown): if the first argument is a port or file descriptor,
1395 (scm_truncate_file): new procedure.
1396 Add DEFER/ALLOW INTS to a few other procedures.
1397 (scm_fsync): new procedure.
1398 (scm_open_fdes): new procedure.
1399 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1401 (scm_fcntl): the first argument can now be a file descriptor. The
1402 third argument is now optional.
1404 * posix.c (scm_execl, scm_execlp): make the filename argument
1405 compulsory, since omitting it causes SEGV.
1406 (scm_sync): return unspecified instead of #f.
1407 (scm_execle): new procedure.
1408 (environ_list_to_c): new procedure.
1409 (scm_environ): use environ_list_to_c. disable interrupts.
1410 (scm_convert_exec_args): take pos and subr arguments and
1411 improve error checking.
1413 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1415 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1416 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1417 argument to SCM_ASSERT. Furthermore, the name of the function
1418 should be passed as first argument when signalling
1419 SCM_WNA. (Thanks to Thomas Morgan)
1421 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1422 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1423 dispatches on the number of actual args has a default case
1424 reporting an internal error. This is a vestige from a version
1425 that mallocated a SCM vector to hold the arguments. In the
1426 current version this check is too late: if it ever happens we will
1427 have already overstepped the bounds of the array.
1429 Also, the patch [...] adds a check for too many actual arguments."
1431 mdj: Removed check for "internal programming error".
1433 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1435 * gh_io.c (gh_write): New function.
1437 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1438 throw.c (scm_internal_stack_catch): New sibling to the other catch
1439 functions. Code moved from gh_eval.c.
1440 throw.h: Added header.
1441 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1442 scm_internal_stack_catch.
1444 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1446 * ioext.h: fix up prototypes.
1447 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
1448 Scheme name is now dup->fdes.
1449 (scm_dup_to_fdes): make the second argument optional and
1450 fold in the functionality of scm_primitive_dup.
1451 (scm_primitive_dup): deleted.
1453 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1455 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1456 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1457 ultrix are defined. Use setvbuf instead of setbuf.
1458 (scm_setvbuf): new procedure.
1459 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1460 (scm_setfileno): moved from ioext.c.
1461 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
1462 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
1464 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1466 * fluids.c (scm_fluid_p): New function.
1467 * fluids.h (scm_fluid_p): New prototype.
1469 Sat Jul 26 21:33:37 1997 Marius Vollmer <mvo@zagadka.ping.de>
1471 * print.c (scm_iprin1): Enter printed structures into the print
1472 state as nested data while they are printed.
1473 (print_state_fluid, print_state_fluid_num): New variables.
1474 (scm_init_print): Initialize them.
1475 (scm_iprin): If print_state_fluid carries a print_state, use that
1476 instead of creating a new one.
1477 (scm_printer_apply, apply_stub, struct apply_data): New
1478 definitions to help with calling printer functions written in
1480 * print.h (scm_printer_apply): New prototype.
1482 * struct.c (scm_print_struct): Use scm_printer_apply to call the
1483 user defined struct printer.
1485 * dynwind.c (scm_dowinds): Handle fluids on the wind list.
1486 * fluids.h (scm_internal_with_fluids, scm_with_fluids,
1487 scm_swap_fluids, scm_swap_fluids_reverse): New prototypes.
1488 * fluids.c (scm_internal_with_fluids, scm_with_fluids,
1489 scm_swap_fluids, scm_swap_fluids_reverse): New functions.
1491 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
1493 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1494 SCM_ASSERT: arg comes before pos.
1496 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1498 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1499 to a list of length zero correctly.
1501 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1503 Supply an `fgets' method for port objects to do fast line i/o.
1504 * ioext.c (scm_read_line): New function.
1505 * genio.c (scm_gen_read_line): New function.
1506 * fports.c (scm_fgets): New function.
1507 (scm_fptob, scm_pipob): Add scm_fgets method.

1513 * strports.c (scm_stptob): Supply generic fgets method.
1515 Mon Jul 21 04:03:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1517 * ioext.h: removed scm_duplicate_port prototype.
1519 * ioext.c (scm_primitive_dup2): return the new file descriptor
1520 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
1522 (scm_fdopen): bug fix: don't try to make port unbuffered until its
1523 stream has been set.
1524 (scm_duplicate_port): deleted, there's now an implementation in
1526 (scm_primitive_dup2): do nothing if newfd == oldfd.
1528 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
1530 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
1533 * ioext.h: new prototypes.
1534 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
1536 * fluids.c (next_fluid_num): don't do
1537 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
1539 * ports.h: prototypes too.
1540 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
1542 * fports.h: prototype too.
1543 * fports.c (scm_evict_ports): moved from ioext.c.
1545 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
1547 * ports.c (scm_close_port): return a boolean instead of unspecified.
1548 throw an error if an error other than EBADF occurs.
1550 * filesys.h: scm_close prototype.
1551 * filesys.c (scm_close): new procedure, can close file descriptors
1552 and ports (scsh compatible).
1554 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
1557 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
1559 * fluids.c, fluid.h: New files.
1560 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
1561 (modinclude_HEADERS): Added "fluids.h"
1563 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to
1564 scm_init_fluids to initialize the fluid machine.
1565 (scm_start_stack): Initialize the fluids of the first root with
1566 scm_make_initial_fluids.
1568 * root.h: Added "fluids" member to scm_root_state.
1569 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
1570 (scm_make_root): Call scm_copy_fluids to make fluid bindings
1571 unique for the new root when it has a parent.
1573 * smob.h: Include "libguile/print.h" to make scm_print_state
1576 * dynl.c (free_dynl_obj): New function to free the dynamic object
1577 data. (dynl_smob): Use it.
1578 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
1579 the dynamic object data below the linking of the object to avoid
1580 memory leak when the linking code throws an error. Now the code
1581 leaks a whole dynamically linked library when must_malloc throws,
1582 but that should be much less likely.
1584 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
1586 Changes to compile under gnu-win32, from Marcus Daniels:
1587 * stime.c (tzset): If tzset isn't provided, make it a NOP.
1588 (scm_localtime): Change SCM_EOF to SCM_EOL.
1589 (scm_mktime): Likewise.
1590 * socket.c: Don't include sys/un.h unless autoconf tells
1591 us Unix domain sockets are available.
1592 (scm_fill_sockaddr): Ignore Unix domain code.
1593 (scm_addr_vector): Likewise.
1594 (scm_init_addr_buffer): Likewise.
1595 (scm_socketpair): Don't include unless socketpair was
1596 found during autoconf.
1597 * simpos.c (SYSTNAME): Treat cygwin like Unix.
1598 * scmsigs.c (scm_pause): Don't include unless pause was found
1600 * posix.c (scm_getgroups): Don't include unless support function
1601 was found during autoconf (in this case, getgroups).
1602 (scm_setpwent): For setpwent.
1603 (scm_setegid): For setegid.
1604 * net_db.c (scm_inet_netof): Don't include unless support
1605 function was found during autoconf (in this case, inet_netof).
1606 (scm_lnaof): For inet_lnaof.
1607 (scm_inet_makeaddr): For inet_makeaddr.
1608 (scm_getnet): For getnetent, getnetbyname, getnetbyaddr.

1619 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
1620 scm_misc_error, not SCM_EOF.
1622 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
1623 arguments for formatting the error message, not SCM_BOOL_F. I
1624 think this is left over from the (eq? '() #f) days.
1626 * read.c (recsexpr): Give this a dummy definition if
1627 DEBUG_EXTENSIONS isn't #defined.
1629 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
1631 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
1634 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>
1636 * root.c (cwdr_outer_body): Bugfix: Pass `c' instead of `&c' to
1639 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
1641 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
1642 alloca.lo will be included in @LIBLOBJS@. Something better than
1643 this should be possible.
1644 * Makefile.in: Regenerated.
1646 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1648 * simpos.h: prototype for scm_primitive_exit.
1649 * simpos.c (scm_primitive_exit): new procedure, terminates the
1650 process without unwinding the stack.
1652 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
1654 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
1655 argument and logior its components together, so the user doesn't
1656 have to do this explicitly. Also, if regexp/basic is supplied, then
1657 turn off REG_EXTENDED.
1658 (scm_init_regex_posix): New regexp/basic symbol.
1659 (REG_BASIC): #define this if it is not already present.
1661 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1663 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
1664 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
1665 (CLEANFILES): New target, clean versiondat.h, libpath.h.
1666 (DISTCLEANFILES): New target, clean *.x.
1667 * Makefile.in: Regenerated.

1672 years in usage message.
1674 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
1675 * Makefile.in: Regenerated.
1677 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
1678 flag; I don't think we support it.
1679 (scm_make_regexp): Make sure the user doesn't pass the
1682 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
1684 (scm_init_regex_posix): Define constants for the REG_mumble flags;
1685 name them according to the SCSH convention: regexp/mumble.
1687 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
1689 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
1691 * Makefile.am (libpath.h): Include the values of all the standard
1692 Makefile directory variables. Print a message, but don't print
1694 (versiondat.h): Print a message, but don't print all the commands.
1695 * load.c: #include "alist.h".
1696 (init_build_info): New function.
1697 (scm_init_load): Call it.
1698 * Makefile.in: Regenerated.
1700 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
1702 * root.c: Establish a reliable catch-all handler for the new root.
1703 After all the Scheme handler function might signal an error too,
1704 and we don't want to lose that.
1705 (cwdr_inner_body): Renamed from cwdr_body.
1706 (cwdr_outer_body): New function, to establish the user's handler,
1707 and pass control to cwdr_inner_body.
1708 (cwdr): Establish the reliable catch-all handler here, and pass
1709 control to cwdr_outer_body.
1710 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
1711 the user's handler through to cwdr_outer_body.
1712 * throw.c (scm_handle_by_message): Move guts into....
1713 (handler_message): New static function.
1714 (scm_handle_by_message_noexit): New function.
1715 * throw.h (scm_handle_by_message_noexit): New prototype.
1717 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
1718 across this. Only works on GCC. Otherwise, we hope for the best.
1719 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
1720 the feeling that real thread systems will not need this...
1722 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
1724 Try to detect when people are using one version of libguile and a
1725 different version of ice-9. People have been skewing things and
1726 sending in bug reports.
1727 * Makefile.am (versiondat.h): New file to generate.
1728 * version.c: #include "versiondat.h", to get version info.
1729 (scm_libguile_config_stamp): New function.
1730 * script.c: #include "version.h".
1731 (scm_compile_switches): Call scm_version to get version number.
1732 * scmconfig.h.in, Makefile.in: Regenerated.
1733 * Makefile.in: Regenerated.
1735 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
1736 primitive definitions under their Scheme names.
1738 * Makefile.am (libguile_la_LDFLAGS): Update library version to
1739 1:2. Helps avoid confusion between installed and uninstalled libs.
1741 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
1744 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
1745 backslash from definition; this should be used like: GDB_INTERFACE;
1747 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1749 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
1750 new port unbuffered until its stream has been set.
1752 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
1754 * ports.h: new prototype.
1755 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
1757 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
1759 Make things compile neatly under Sun's C compiler.
1760 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
1761 * extchrs.c (xmbtowc): Make the second arg a normal char, not
1762 unsigned, because that's what the ANSI function takes.
1763 * extchrs.h (xmbtowc): Corresponding change to prototype.
1764 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
1766 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
1767 argument plain char *.
1768 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
1770 * tag.c (scm_tag): Remove unreachable statement.
1771 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
1772 top of the word, it should be unsigned.
1774 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
1775 is defined, to avoid warnings; it's only used in the
1776 conflict-checking code. Which might go away anyway.
1777 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
1778 conditionals; put the label definition in an #if too, to stifle
1781 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
1782 ChangeLog-threads in the distribution.
1783 * Makefile.in: Regenerated.
1785 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1787 * guile-snarf.in: Changed regexp to support CPPs that insert
1788 whitespace between lexical tokens (which munges the `%%%' snarf
1791 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1793 * load.c (scm_init_load_path): Append $(datadir)/guile to
1794 %load-path, so modules do not have to be installed in Guile's
1795 current version directory.
1797 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
1799 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
1800 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
1801 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
1802 call the sysdep functions with deferred ints.
1803 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
1804 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
1805 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
1808 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
1811 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
1813 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
1815 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
1817 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
1820 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
1822 * eval.c (scm_lookupcar1): New procedure to cope with a race
1823 condition during lookup (when using threads).
1824 (scm_lookupcar): Implement in terms of scm_lookupcar1.
1825 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
1828 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
1830 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
1831 supplied. (Change from Tim Pierce.)
1833 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
1835 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
1836 23:47:01 1997" changelog: Slots are now initialized with `#f' by
1837 default and not `()'. `#f' is the canonical non-value in Scheme,
1840 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1842 * struct.c (struct_printer): New variable that holds a handle on
1843 the Scheme variable *struct-printer*. This variable can be set by
1844 Scheme code to override the printing of structures.
1845 (scm_print_struct): If struct_printer is set, call it. If it is
1846 not set, or returns #f, print the structure in the old fashion.
1847 Include "eval.h" for scm_apply.
1849 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
1851 * struct.c (scm_struct_ref, scm_struct_set_x): Use
1852 scm_struct_i_n_words to get the number of fields, not
1853 -scm_struct_n_extra_words.
1855 On the route to fancier struct printing:
1856 * struct.c (scm_print_struct): New function to print a structure.
1857 Include "genio.h" to support it. This function doesn't do
1858 anything interesting right now, but I think it should be here
1860 * struct.h: Include "print.h" and add prototype for
1862 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
1863 print structures ourself.
1865 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
1867 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
1868 before applying the handler in case it doesn't return.
1870 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
1872 * scmsigs.h, async.h: updated.
1874 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
1877 * posix.c (scm_uname): interpret only negative values as an error.
1878 Solaris normally returns a positive value.
1880 * script.c (scm_compile_shell_switches): if we are not going into
1881 an interactive repl, set scm_mask_ints to zero so that asyncs can
1884 * simpos.c (scm_system): don't ignore/unignore signals around
1887 * posix.c (scm_open_pipe): don't ignore/unignore signals around
1890 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
1891 done in boot-9.scm instead.
1893 * scmsigs.c, async.c: Major rewriting of signal handling code.
1894 (scm_sigaction): new procedure.
1895 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
1897 (scm_raise): return unspecified, throw error on failure.
1899 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1901 * regex-posix.c (scm_init_regex_posix): Register the "regex"
1902 feature, to help boot-9.scm decide whether to import the regex
1905 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1907 * eval.c: Include scmconfig.h at the beginning of the file so that
1908 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
1911 * regex-posix.c: #include "_scm.h" before conditionally #including
1912 <regex.h>; the former defines HAVE_REGCOMP.
1914 * regex-posix.c: #include <regex.h> conditionally, so the file is
1915 CPP'able (for dependency scanning) even on systems that don't have
1918 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
1920 Add new R4RS-compliant syntax for keywords.
1921 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
1922 regardless of the setting of the `keywords' read option.
1923 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
1924 can be re-read no matter what the setting of the `keywords' read
1927 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
1929 Add support for POSIX regular expressions.
1931 * regex-posix.c, regex-posix.h: New files. (Some code
1932 is taken liberally from rx/rgx.c in the old Guile dist.)
1934 * init.c: Include regex-posix.h.
1935 (scm_boot_guile_1): Call scm_init_regex_posix.
1937 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
1938 Add regex-posix.[ch] sources.
1939 * Makefile.in: Regenerated.
1941 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
1942 to do this automatically? It didn't for me, bleh.)
1944 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
1946 * fports.c (print_pipe_port): New function.
1947 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
1948 latter doesn't even take the right arguments.
1950 * Makefile.am: Increment shared lib revision number. I think
1951 sometimes the uninstalled Guile finds the installed shared lib;
1952 Gord says doing this might help. As things turned out, I can't
1953 say whether it does.
1954 * Makefile.in: Regenerated.
1956 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
1957 passing it as the closure argument to scm_boot_guile. (Bill
1960 * ports.c (print_void_port, putc_void_port, puts_void_port,
1961 write_void_port, flush_void_port, getc_void_port, close_void_port,
1962 noop0): Use ANSI prototypes instead of K&R declarations, so the
1963 initialization of void_port_ptob gets aggressively type-checked.
1964 Fix arguments of print_void_port and write_void_port. (Bill

1998 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
2000 * script.c (scm_find_executable): Use prototype-style definition
2001 here; apparently it's not quite right to have const in a prototype
2002 and then use a K&R declaration. I wonder if stuff like this will
2003 go away if we compile with -Wrequire-prototypes, or whatever that
2004 is... (Bernard URBAN)
2006 * scmhob.h: New text from Bernard URBAN.
2008 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
2010 * script.c: Don't #define const on hpux. Configure takes care of
2011 this. (Thanks to Larry Schwimmer.)
2013 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
2014 decide whether to #include <unistd.h>, instead of listing a bunch
2015 of systems. Don't #include stdio twice. Removed dyked-out
2016 definition of scm_find_impl_file.
2018 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2020 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
2021 library version info to 1:0.
2022 * Makefile.in: Regenerated.
2024 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,
2025 gdb_interface.h, gdbint.c, gdbint.h, gh_data.c, gh_init.c,
2026 gh_io.c, gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c,

2028 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2029 throw.c: Update copyright years; these files have been worked on
2030 significantly in 1997, but only had copyright years for 1996.
2031 Also, change name of copyright holder on some from Mikael
2032 Djurfeldt to Free Software Foundation; he has signed papers
2033 assigning the changes to the FSF.
2035 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2036 reason not to give the user the option.
2038 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2039 Return #f on end-of-file when scanning table (i.e. when called
2040 with no arguments). Try to catch errors, when we can.
2041 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2043 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2044 external declarations. These are useful.
2046 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2048 * posix.c: don't include <sys/select.h> or define macros for
2049 select, since they were not used in this file.
2051 * filesys.c (scm_select): make the fifth parameter microseconds,
2052 not milliseconds. let the fourth parameter be either a real value
2053 or an integer or #f. The first, second and third arguments can
2054 now be vectors: the type of the corresponding return set will be
2056 (set_element, get_element): new static procedures.
2058 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2060 * strports.c (scm_eval_string): New function.
2061 (scm_eval_0str): Trivially re-implemented in terms of
2063 * strports.h (scm_eval_string): New extern decl.
2065 * net_db.c (h_errno): Add extern decl for this.
2067 * fports.c (local_pclose): New function.
2068 (scm_pipob): Use it in the initializer here.
2071 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2072 Use a meaningful error message when signalling an error. For
2073 this, scm_gethost must check h_errno rather than errno.
2075 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2077 * Makefile.in: Regenerated, using automake-1.1p.
2079 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2081 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2082 not SCM_UNSPECIFIED.
2084 * script.c (scm_compile_shell_switches): don't append (quit) if
2086 (scm_shell): call scm_exit_status and exit on the result of the
2089 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2091 Ensure that shared substrings are handled properly when passed to
2092 a system call or other foreign function. Many thanks to Tim
2094 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2095 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2096 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2097 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
2098 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
2099 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2100 (scm_display_error_message): use RO macros when strings may be RO.
2101 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2102 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2103 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
2104 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
2105 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
2106 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
2107 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
2108 scm_strftime), vports.c (scm_make_soft_port): use
2109 SCM_COERCE_SUBSTR to make sure shared substrings are
2112 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2114 * error.c (scm_error): Add newline to error message.
2116 * init.c (scm_init_standard_ports): Doc fix.
2118 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2120 * dynl-shl.c: Completely replaced with new code from Bernard
2123 * script.c (scm_ice_9_already_loaded): New variable.
2124 (scm_compile_shell_switches): Use it.
2126 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2128 * filesys.c (scm_input_waiting_p): add missing third argument to
2131 * stime.c (scm_localtime): copy the result of localtime before
2132 calling gmtime in case they share a buffer.
2133 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
2136 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2138 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2140 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2142 * Makefile.am (check-local): New target, which causes 'make check'
2143 to run gh_test_c and gh_test_repl, with some trivial input.
2144 * Makefile.in: Rgnrtd.
2146 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2148 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2151 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2153 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2154 sure how this was supposed to work.
2155 (scm_async_click): don't send SCM_TICK_SIGNAL.
2156 (scm_init_async): don't initialize %tick-thunk.
2158 * the following change doesn't affect the Scheme interface:
2159 gc-thunk is called at the end of garbage collection. however it's
2160 no longer implemented by pretending it's a signal.
2162 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2163 system async corresponding to scm_gc_thunk.
2164 * async.h: declare scm_gc_async.
2165 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2166 gc-thunk directly, instead of going through a signal handler.
2167 (scm_gc_async): new variable, points to the GC system-async.
2168 (scm_init_async): save the GC async as scm_gc_async instead
2169 of using system_signal_asyncs.
2170 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2172 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2174 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2175 Don't screw up if we're interrupted.
2176 * Makefile.in: Regeneradet.
2178 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2180 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2182 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2183 we're not using AM_INIT_GUILE_MODULE any more.
2184 * Makefile.in: Reneregated.
2186 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2188 Functions for finding variable bindings, grace à Tim Pierce.
2189 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2190 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2192 Get 'make dist' to work again.
2193 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2194 * Makefile.in: Regenerated, like a surry without a fringe on top.
2196 Changes for reduced Guile distribution: one configure script,
2198 * configure.in, configure: Removed.
2199 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2200 real configure script lives.
2201 * Makefile.in, scmconfig.h.in: Regenerated.
2203 * init.c: #include "script.h", to get prototype for script.c's
2206 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2208 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2209 scm_must_malloc, not raw malloc.
2211 * script.c (scm_compile_shell_switches): Dyke out debugging output
2214 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2216 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2218 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2219 system has them. Hope this is safe. Previously
2220 sys/timeb.h was included if HAVE_FTIME was defined or if
2221 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2222 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2224 * ioext.c (scm_setfileno): add missing third argument to
2225 scm_misc_error call.
2227 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2229 * eq.c (scm_equal_p): Correctly compare strings of different
2230 varieties. (Thanks to Tim Pierce.)
2232 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2234 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2235 #! block comment must occur on a line all by itself.
2237 Move most of the guts of shell command processing into libguile,
2238 so guile.c can be very small (and eventuallly auto-generated. (I
2239 mean, generated mechanically, not self-generated. Hmm.))
2240 * guile.c, script.c, script.h: New source files.
2241 * init.c (scm_boot_guile_1): Call scm_init_script.
2242 * libguile.h: #include "script.h".
2243 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2244 targets, for new executable.
2245 (libguile_la_SOURCES): Mention script.c.
2246 (modinclude_HEADERS): Add script.h.
2247 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2248 not dynamic linking is enabled. This is because we're generating
2249 executables now. Move CY_AC_WITH_THREADS call after those, so the
2250 values of cy_cv_threads_libs captures the libs chosen above.
2251 * Makefile.in, configure, aclocal.m4: Regenerated.
2253 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2254 We don't maintain this interface any more, and it just confuses
2257 * alloca.c: #include <scmconfig.h>, not <config.h>.
2258 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2259 it'll get included in disties.
2261 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2263 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2264 be distributed, because they confuse people.
2265 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2267 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2269 * configure.in: check for presence of gethostent (not present on
2270 OpenBSD by default).
2271 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2272 * configure, scmconfig.h.in: Regenerated.
2274 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2276 * backtrace.c (scm_backtrace): Split message string across
2277 newlines properly. GCC is more tolerant of this than other
2280 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2282 Merge threads directory into libguile.
2283 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2284 threads.h: New source files.
2285 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
2286 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2288 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2289 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2290 coop-threads.c.cygnus, coop-threads.h.cygnus.
2291 * configure.in: If we're using threads, include threads.o in
2293 * _scm.h, libguile.h: threads.h lives in this directory now.
2294 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2295 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2296 currently used, but brought along for information's sake.
2297 * ChangeLog-threads: log from old 'threads' directory.
2298 * Makefile.in, configure: Rebuilt.
2300 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2302 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2305 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2307 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2309 Merge GH interface library into libguile.
2310 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2311 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2312 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2313 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2315 (EXTRA_libguile_la_SOURCES): ... here.
2316 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2317 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2318 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2319 New variables, describing how to build the gh test programs.
2320 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2321 build the test programs, and we probably should have been linking
2322 libguile.la against them all along, to support AIX shared libs.
2323 Add cflags for threads to CFLAGS; add libs for threads to new
2324 variable THREAD_LIBS, used in Makefile.am.
2325 * ChangeLog-gh: log from old `gh' subdirectory.
2326 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2328 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2330 * acconfig.h: Undo change of Apr 9; including the definition of
2331 PACKAGE in the guile headers conflicts with applications' own
2333 * scmconfig.h.in: Regenerated.
2335 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
2337 * filesys.c (scm_fcntl): New function from Roland McGrath.

2339 * filesys.h: Added prototype.
2341 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
2342 when PROC is receiving no arguments.
2344 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2346 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2347 have S_IFSOCK. This is the case under Ultrix.
2349 * posix.c (scm_status_exit_val, scm_status_exit_val,
2350 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2351 Ultrix versions of WIFSTOPPED, etc., which assume that their
2352 arguments are lvalues (hmm).
2354 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2356 * eval.c: Doc fixes.
2358 * throw.c: Doc fixes; rearranged.
2360 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
2362 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
2364 * acconfig.h: Added entry for PACKAGE.
2365 * scmconfig.h.in: Regenerated.
2367 Changes to work with automake-1.1n, which has better libtool support.
2368 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2369 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2371 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2373 * Makefile.in: Rebuild.
2375 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2377 * stime.c (scm_mktime): take an optional zone argument.
2378 (scm_localtime): check putenv return value.
2379 (scm_strftime, scm_strptime): moved from posix.c. move #include
2381 stime.h, posix.h: update prototypes.
2382 (bdtime2c, setzone, restorezone): new static procedures.
2383 (scm_mktime, scm_strftime): use them.
2384 (scm_strftime): don't call mktime before strftime. Use
2385 filltime for return value.
2386 (filltime): convert NULL zname to #f.
2387 (scm_strptime): return a count of characters consumed, not
2388 the remaining string.
2390 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2392 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2393 (scm_mktime): likewise.
2395 Uncomment localtime and mktime.
2397 * configure.in: add AC_STRUCT_TIMEZONE.
2399 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2401 * stime.c (scm_init_stime): don't define ticks/sec.
2402 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2403 return value problem and is still portable.)
2405 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2407 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2408 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2409 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2410 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2411 cpp_err_symbols.c): Corresponding changes.
2412 * Makefile.in: Regenerated.
2414 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2416 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2417 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2418 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2419 * putenv.c: new file, from sh-utils 1.12.
2421 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2422 since allocation isn't for Scheme objects.
2423 (scm_putenv): copy strings before placing in the environment.
2425 * stime.c (scm_current_time): throw an error if time returns -1,
2426 instead of returning #f.
2427 (scm_get_internal_real_time, scm_get_internal_real_time): use
2428 scm_long2num for return value instead of SCM_MAKINUM.
2430 * stime.h: prototypes updated.
2432 * stime.c (scm_time_in_msec): apparently unused, deleted.
2434 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2436 * configure.in: check for gettimeofday.
2438 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2439 which may be more usefully portable than a gettimeofday interface.
2441 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2443 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
2445 * Makefile.in: Regenerated.
2447 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2449 * stime.c (filltime): recovered static procedure.
2450 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2453 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2454 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2456 * posix.c (scm_mknod): split the mode argument into type and perms
2457 arguments, like the extra fields returned by stat.
2459 * fports.c (scm_pipob): set the close, free and print procedures.
2460 (scm_close_pipe): new procedure.
2462 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2463 define them in boot-9.scm
2465 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2467 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2468 wan't defined. Don't include fd.h.
2470 * Previously fd.h was regenerated whenever configure was run,
2471 forcing a couple of files to be recompiled.
2473 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2474 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2475 Check for _fileno as well as _file.
2477 * ioext.c: don't fd.h.
2478 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2481 * Change the stratigy for getting information about errno
2482 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2483 generating lists of symbols during the build process, which will
2484 not always work, include comprehensive lists in the distribution.
2485 To help keep the lists up to date, the "check_signals" and
2486 "check_errnos" make targets can be used.
2488 * configure.in: don't check for a command to extract errno codes.
2489 * Makefile.am: update file lists, remove errnos.list and errnos.c
2490 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2491 check_errnos targets.
2492 (CLEANFILES): remove errnos.c and errnos.list, add
2493 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2494 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2495 * errnos.default: deleted.
2496 * cpp_signal.c: new file.
2497 * cpp_errno.c: renamed from errnos_get.c.
2498 * cpp_err_symbols, cpp_sig_symbols: new files.
2499 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2500 * error.c (scm_init_error): #include cpp_err_symbols instead of
2502 * posix.c (scm_init_posix): don't intern signal symbols. #include
2505 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2507 * strop.c (scm_i_index): allow the lower bound to be equal to the
2508 length of the string, so a null string doesn't always give an error.
2510 * posix.h: new prototypes.
2511 * posix.c (scm_status_exit_val, scm_status_term_sig,
2512 scm_status_stop_sig): new functions, as in scsh. They break down
2513 process status values as returned by waitpid.
2515 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2517 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2518 configure doesn't know about it.
2520 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2522 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2524 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2525 which defines C variables with global linkage.
2527 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2529 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2532 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2534 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2535 has time to check why this doesn't work well with continuations.
2537 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2539 * Fix shell syntax error; some shells won't tolerate
2540 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2542 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2544 * posix.c (scm_uname): throw an error if uname fails instead
2547 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
2549 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
2552 * async.c (scm_ints_disabled): definition moved from error.c.
2554 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2556 * acconfig.h: Removed PACKAGE.
2558 * scmconfig.h.in: Regenerated.
2560 * snarf.h: g++ says it's non-portable not to specify the first
2561 argument in a varargs declaration. I introduced the first
2562 argument by using preprocessor conditionals.
2564 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
2566 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
2567 (scm_freopen): use RO string macros for filename and modes.
2568 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
2570 * posix.c (scm_getgrgid): simplify conversion of name to C string.
2571 (scm_mknod): use RO string macros for path.
2573 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
2574 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
2576 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2577 use SCM_ROSTRINGP and SCM_ROCHARS.
2579 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2581 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
2584 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
2585 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
2586 support for byte vectors.
2588 * print.c (scm_iprin1): Limit number of vector elements printed
2589 according to pstate->length.
2591 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2593 * backtrace.c (scm_display_error_message): don't segv if message
2596 * error.h: prototype for scm_error_scm.
2598 * error.c (scm_error_scm): new procedure, reimplements scm-error
2599 in C and uses scm_error.
2601 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2603 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
2604 pointer to the Scheme variable read-hash-procedures and intern it
2605 in scm_init_read. Modify scm_read_hash_extend and
2606 scm_get_hash_procedure to use the pointer.
2608 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2610 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
2611 (SCM_KEYWORD_STYLE): defined.
2613 * read.c (scm_read_opts): add a keywords option. This isn't a
2614 boolean option, in case someone wants to add support for DSSSL
2616 Setup scm_keyword_prefix symbol.
2617 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
2619 I've left keyword support disabled by default, since it doesn't
2620 seem to break the module system and it gives R4RS standard behaviour.
2621 It can be reactivated with (read-set! keywords 'prefix).
2623 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2625 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
2626 before constructing arbiter.
2628 * eval.c (scm_m_define): Bugfix: Check that the object is a
2629 closure before setting the procedure property!
2631 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
2633 * ports.c: Removed `ungetc-char-ready?'.
2635 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
2637 * read.c (scm_init_read): intitialise scm_read_hash_procedures
2638 (idea from Mikael: make it a pair so scm_permanent object only
2640 (scm_read_hash_extend): don't call scm_permanent_object.
2641 (ideas from Mikael): if chr is already in the list, replace its
2642 procedure instead of appending it again. If proc is #f, remove
2644 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
2646 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
2648 * gdbint.c (gdb_read): update scm_lreadr usage.
2650 * load.h: update prototypes.
2652 * load.c (scm_primitive_load, scm_read_and_eval_x,
2653 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
2655 * read.h: add prototype for scm_read_hash_extend. Change args for
2658 * read.c (scm_read_hash_procedures): new variable.
2659 (scm_read_hash_extend): new procedure.
2660 (scm_get_hash_procedure): new procedure.
2661 (scm_lreadr): use scm_get_hash_procedure instead of an argument
2662 for extended # processing.
2663 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
2664 scm_read_token): remove case_i, sharp arguments. Change callers.
2666 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
2668 * read.h (SCM_N_READ_OPTIONS): increase to 3.
2669 (SCM_CASE_INSENSITIVE_P): define.
2671 * read.c: add case-insensitive option to scm_read_opts.
2672 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
2673 to determine whether to convert symbol case.
2674 (default_case_i): definition removed.
2675 * read.c (scm_read_token): if case_i, downcase ic before doing
2678 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2680 * configure.in: Added configuration option `guile-debug'.
2681 Configure with --enable-guile-debug if you want a bunch of extra
2682 functions used for debugging when developing Guile.
2684 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
2686 * procs.c (make-cclo): New undocumented debugging procedure: Make
2687 compiled closure with internal procedure PROC and length LENGTH.
2688 Only compiled if GUILE_DEBUG is defined.
2690 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
2692 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
2694 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
2696 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
2697 with 3 or more args internally to the evaluator.
2699 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2701 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
2702 with 3 or more args internally to the evaluator. This is mainly
2703 because we don't want to pass entry and exit points of the
2704 debug support twice, but it also seems to increase the speed of
2705 the evaluator for such calls (e. g. (+ 1 2 3)).
2707 * backtrace.c (scm_display_application): New procedure:
2708 display-application; Set fancy printing parameters individually
2709 for different types of display (backtrace, error, application).
2710 (These should of course be customizable!)
2712 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
2713 clear the CHECK-flags.
2715 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2717 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
2719 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2721 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
2722 from pairs with a GLOC in the car.
2724 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
2725 otherwise `symbol-hash' will behave badly.
2726 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
2727 we get segmentation fault!
2729 * symbols.c: Added #include "weaks.h". New functions:
2730 `builtin-bindings' and `builtin-weak-bindings'. (These will be
2731 moved to an extraneous library when we split libguile.)
2733 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2735 * filesys.c (scm_stat): stat now takes fport arguments too as
2736 documented in the manual.
2738 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2740 * debug.c (scm_single_step): Bugfix: Call continuation with
2741 scm_call_continuation instead of throwing to it.
2743 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
2745 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
2746 argument wasn't declared to be optional.
2748 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2750 * stime.c (scm_init_stime): Add feature "current-time".
2752 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2754 * throw.h: prototype for scm_exit_status.
2755 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
2756 args to derive an exit status. Allows (quit) to work from a
2758 (scm_exit_status): new function.
2761 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2763 * eval.c (scm_deval): Removed some old code.
2764 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
2766 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
2769 * symbols.c (msymbolize): Bugfix: Must initialize property list to
2772 * procs.c: Introduce the existent C function scm_thunk_p at the
2773 Scheme level as well.
2775 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2777 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
2778 used from C to easily lookup the value of a symbol in the current
2781 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2783 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
2784 scm_init_unif in this file. This will also fix a previous problem
2787 * configure.in: Added AM_MAINTAINER_MODE
2789 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2791 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
2794 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
2796 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
2797 source files that are not always included in libguile but should
2798 have their dependencies calculated by automake. This variable is
2799 recognized by automake, no further magic is needed.
2800 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
2801 to deal exclusively with *.lo files, as it seems. The *.o files
2802 are built automatically when the corresponding *.lo file gets
2805 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
2807 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
2810 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
2812 * unif.c (scm_array_set_x): minor change to argument error checking.
2814 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
2816 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
2817 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
2818 They should only be included in the library at configure.in's
2820 (libguile_la_LDADD): Include the appropriate .lo files here.
2821 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
2822 so we know when to build them (and their .lo bretheren).
2823 * configure.in (LIBLOBJS): New substituted variable. We let
2824 configure decide which .o files to include in LIBOBJS, and then
2825 put the corresponding list of .lo files in LIBLOBJS. The latter
2826 is what we pass to libtool.
2827 * Makefile.in, configure: regenerated.
2829 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
2831 * symbols.c (scm_sysintern0): New function. Contains the core of
2832 old scm_sysintern but doesn't take a second value argument.
2833 (scm_sysintern): Now uses scm_sysintern0.
2834 (scm_sysintern_no_module_lookup): Renamed to
2835 scm_sysintern0_no_module_lookup and doesn't take a second value
2836 argument any longer.
2838 * symbols.h (scm_sysintern0: Added declaration.
2840 * options.c (scm_init_opts): Use scm_sysintern0 instead of
2841 scm_sysintern when interning option keys. Otherwise we risk
2842 destroying the values of already interned variables.
2844 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
2845 scheme-level boolean (use SCM_NFALSEP).
2847 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
2849 (scm_backtrace): New function. (C version of old function from
2850 boot-9.scm) Motivation: Make it possible to display backtraces
2851 without depending on boot-9.scm. (I'm uncertain if this
2852 motivation is good enough...)
2854 * root.h (scm_root_state): Add member the_last_stack_var.
2855 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
2857 * root.c (mark_root): Mark scm_the_last_stack_var.
2859 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
2862 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
2864 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
2865 1. mark_lazy_catch didn't mark the smob.
2866 2. Both functions above have standard variants:
2867 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
2868 free_lazy_catch --> scm_free0.
2870 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
2872 * throw.c (scm_internal_lazy_catch): New function.
2873 (scm_lazy_catch): Rewritten to use it.
2874 (scm_ithrow): Handle the new lazy catch representation.
2875 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
2876 that doesn't have a jmpbuf is a lazy catch clause.
2877 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
2878 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
2879 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
2881 (scm_init_throw): Register the new lazy-catch smob type.
2882 * throw.h (scm_internal_lazy_catch): decl for new function.
2884 * throw.c (scm_internal_catch): Doc fixes.
2886 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
2887 configure.in. Including this might cause problems if applications
2888 that link against libguile include their own copies of alloca, but
2889 if they're using autoconf, they should be adding libguile to LIBS
2890 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
2891 the copy in libguile, and things will be okay. (I think.)
2893 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2895 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
2897 strop.h: move prototypes too.
2899 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2901 * posix.c (scm_init_posix): don't intern EINTR since it's now done
2904 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
2905 etc. I deleted them from filesys.c long ago, but didn't
2906 notice they were here too (although ineffective since
2907 sys/stat.h wasn't included).
2909 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
2911 * eval.c: Don't define alloca in GCC case. gcc will automatically
2912 use __builtin_alloca if appropriate.
2914 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2916 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
2917 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
2918 that values of automatic variables are preserved. See comments
2919 for safe_setjmp for details.
2921 Change from Thomas Morgan:
2922 * variable.c: Include eq.h.
2923 (var_equal): New function.
2924 (variable_smob): Use var_equal as the discriminator for variables.
2926 * throw.c (s_throw): Remove extraneous declaration.
2928 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
2929 * eval.c: Add necessary CPP cruft to support that.
2930 * configure, Makefile.in, scmconfig.h.in: regenerated.
2932 Change from Thomas Morgan:
2933 * procprop.c (scm_procedure_properties): Convert the Scheme
2934 boolean returned by scm_procedure_p into a C boolean before using
2935 it as a condition for SCM_ASSERT.
2936 (scm_procedure_property): Likewise.
2938 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
2939 indications of Unixness.
2942 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2944 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
2946 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2948 * read.c (scm_lreadr): use scm_misc_error to improve one of the
2949 "unknown # object" error messages.
2951 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
2952 (scm_i_index) and declare it static. Add a 'direction' argument
2953 to indicate what way the search should go.
2954 (scm_i_index): throw out-of-range error instead of wrong-type-arg
2956 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
2957 strop.h: remove scm_i_index, scm_i_rindex prototypes.
2959 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2961 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
2963 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
2964 to avoid clash with various scsh forks.
2966 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
2968 The following two changes (ramap.c, throw.c) are motivated by the
2969 apparent unportability of forward declarations of static arrays of
2970 the form `static foo bar[];'.
2972 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
2973 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
2975 * throw.c (scm_throw): Moved above scm_ithrow.
2977 * options.h: Removed the extern declarations of scm_yes_sym and
2978 scm_no_sym since these are static.
2980 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2982 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
2984 * Makefile.am: remove AWK=@AWK@.
2985 Add a rule for generating errnos.list.
2986 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
2988 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
2989 don't extract errnos, just set a variable (avoids the
2990 need to recompile error.c just because configure is run.)
2992 * unif.h: update prototypes.
2993 * unif.c (scm_uniform_array_read,write): change the offset and
2994 length arguments to start and end, for consistency.
2996 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
2998 * ioext.h: update prototypes.
2999 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
3000 scm_read_line_x, it's a more general procedure using an
3001 interface from scsh. read-line and read-line! are now defined
3003 Note that the new read-line trims the terminator
3004 by default, previously it was appended to the returned string. An
3005 optional argument specifies how to process the terminator (scsh
3006 compatible). For the old behaviour: (read-line port 'concat).
3007 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
3008 returns a pair, but is converted to multiple values if the scsh
3011 socket.h: update prototypes.
3012 * socket.c (scm_recvfrom): for consistency with other procedures,
3013 take start and end as separate optional arguments.
3014 (scm_recv, scm_recvfrom): don't allow the second argument
3015 to be a size, only a buffer. Change the scheme names to
3016 recv! and recvfrom!. Don't return the buffer.
3018 * ioext.h, posix.h: move prototypes too.
3019 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
3020 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
3021 "read.h" and "unif.h".
3022 * ioext.c: include "chars.h"
3024 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
3026 * dynl.c: The dynamic linking and module registration functions
3027 are now defined even when dynamic linking is not available for the
3028 host system. Some of their functionality can be done without
3029 dynamic linking; when it's really needed, they throw errors.
3031 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3033 * configure.in: Only define DYNAMIC_LINKING when one of the system
3034 dependent functions is detected.
3035 * dynl.c (scm_dynamic_func): New function to get the address of a
3036 function in a dynamic object.
3037 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3038 produced by scm_dynamic_func as the thing to call.
3040 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3042 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3043 (scm_register_module_xxx, scm_registered_modules,
3044 scm_clear_registered_modules): New functions.
3046 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3048 * symbols.c (scm_sysintern): Renamed to
3049 scm_sysintern_no_module_lookup.
3050 (scm_sysintern): New function to take the place of the old
3051 scm_sysintern. It uses the current toplevel lookup closure to give
3052 the symbol its value. This is a temporary hack to put packages
3053 like gtcltk into their own module.
3054 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3055 us whether `scm_top_level_lookup_closure_var' has been initialized
3057 * eval.c (scm_init_eval): Set it.
3059 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3061 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3062 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3064 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3066 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3067 scm_sys_dup): deleted: FD capability will be added to other
3069 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3070 scm_fd_free, fd_smob, scm_intern_fd.
3071 (scm_open): renamed from scm_sys_open. Return a port instead of
3072 an FD object. Make the mode argument optional.
3073 (scm_sys_create): deleted, it's just a special case of open.
3074 (scm_init_filesys): move interning of constants O_CREAT etc.,
3075 here (were previously using SCM_CONST_LONG macro).
3076 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3078 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3079 include "fports.h" and <stdio.h>
3080 (scm_stat, scm_select): don't support FD objects.
3082 * error.h: adjust scm_syserror_msg prototype.
3083 * error.c (scm_syserror_msg): take an extra argument for errno.
3084 Using the global value didn't always work, since it could be
3085 reset by procedure calls in the message or args arguments.
3087 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3088 I don't understand why the check was there (and what about the
3091 * strop.c (scm_string_copy): allow shared substrings to be copied.
3093 * unif.h: corresponding change to prototypes.
3094 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3095 recognize two new optional arguments: offset and length. Allow
3096 the port argument to be an integer (file descriptor, for scsh).
3097 Include <unistd.h> for "read" prototype.
3099 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3101 * socket.c: don't include filesys.h.
3103 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3105 * Makefile.am: add AWK=@AWK@ (?)
3107 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3109 Add a rule to generate errnos.c from errnos.
3110 * error.c (scm_init_error): include errnos.c.
3111 * errnos_cnvt.awk: new file, converts the list of errno codes to
3113 * errnos_get.c: new file.
3114 * errnos.default: new file, contains errnos to try if they can't
3115 be extracted from errno.h.
3116 * configure.in: if using GCC, try and extract errno codes from
3120 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3122 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3123 * Makefile.am: Made libguile into a libtool library.
3124 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3125 Set libtool_libs to indicate that libguile is a libtool library.
3126 See guile/ChangeLog for details.
3127 * .cvsignore: ignore "*.lo", the libtool library objects.
3129 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3131 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3132 use htons in getservbyport argument.
3134 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3136 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3137 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3140 * objprop.c (scm_object_property): No need to take the CDR of the
3141 value returned by scm_object_properties, since Aug 20 change.
3143 * configure.in: When checking for struct linger, #include
3144 <sys/types.h> as well as <sys/socket.h>. I've never known
3145 <sys/types.h> to cause any portability problems, and Solaris's
3146 <sys/socket.h> needs it.
3147 * configure: Rebuilt.
3149 I think the Sun compiler has chosen a perverse way to interpret
3150 ANSI declarations combined with K&R definitions. We'll
3151 appease it a little bit. But when it invades France, we fight.
3152 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3153 * print.h (scm_iprlist): Here too.
3154 * numbers.c (scm_divbigdig): Change definition to match
3155 declaration in numbers.h.
3156 * unif.c (scm_makflo): Change definition to match declaration in
3159 * init.c (scm_boot_guile): Don't return the value of
3160 scm_boot_guile_1. This function doesn't return a value;
3161 scm_boot_guile_1 doesn't return a value (or return at all).
3163 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3166 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3167 compile. I have a feeling this function is a bad idea anyway ---
3168 one should always test for features, not systems.
3170 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3171 semicolons. Only pure luck kept this from being noticed earlier.
3173 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3175 * socket.c (scm_recvfrom): Added missing semicolon.
3177 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3179 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3180 the buffer and start and end positions for scsh networking
3183 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3185 * configure.in: Revert previous change to this file; the problem
3186 is due to transient automake weirdness.
3187 * configure: Rebuilt.
3189 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3190 PLUGIN/guile.libs. configure generates the latter from the former.
3191 * Makefile.in: Rebuilt.
3193 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3194 need this if we install scripts, like guile-snarf.
3195 * configure: Rebuilt.
3197 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3199 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3201 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3203 * socket.c (scm_addr_vector): fix faulty scm_listify.
3205 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3207 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3208 style block comment is no longer considered an error.
3210 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3212 * PLUGIN/guile.libs.in: New file.
3213 * PLUGIN/guile.libs: Removed from repository.
3214 * configure.in: Create PLUGIN/guile.libs from
3215 PLUGIN/guile.libs.in. This is for including additonal libraries
3216 needed for dynamic linking.
3217 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3218 instead of PLUGIN/guile.libs.
3220 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3222 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3224 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3225 occurrences of the given element from the list, not just the
3226 first. This is how the Emacs Lisp functions behave, how the
3227 analogous Common Lisp functions behave, and (I believe) how the
3228 older Maclisp functions worked. I realize that this change may
3229 break code, but it seemed better to break it before the Guile
3232 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3233 Their prototypes were already present in gc.h, but they weren't
3235 (scm_init_storage): Initialize scm_protects.
3236 * root.c (scm_protects): New element of scm_sys_protects.
3238 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3240 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3242 * libguile.h: Added #include "libguile/net_db.h".
3244 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3245 30 change. That file is only meant for communication between the
3246 configuration process and load.c. If code linked against libguile
3247 wants to get at the paths mentioned in libpath.h, it can call
3248 functions declared in load.h.
3250 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3252 * libguile.h: Removed #include "libguile/fdsocket.h"
3254 * net_db.c: Added #include <sys/socket.h>.
3256 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3258 * filesys.c (scm_input_waiting_p): use select in preference to
3259 FIONREAD, since the latter doesn't detect EOF.
3260 Throw error if neither select nor FIONREAD available.
3262 * socket.c (scm_connect): take a port, not a fd object.
3263 (scm_fill_sockaddr): throw an error if fam is not recognised.
3264 (scm_bind): use scm_fill_sockaddr.
3265 (scm_listen): take a port, not a fd object.
3266 (scm_accept): take and return a port. return #f in the car if
3267 address can't be got
3268 (scm_sock_fd_to_port): new procedure.
3269 (scm_socket): use scm_sock_fd_to_port.
3270 (scm_addr_vector): throw error if unrecognised address type.
3271 take an extra argument with the calling procedure name.
3272 (scm_getsockname): take a port. return #f if address can't be got.
3273 (scm_getpeername): take a port. return #f if address can't be got.
3274 (scm_recvfrom): take a port. return #f for address component if can't
3276 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3277 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3279 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3281 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3282 use separate data pointers, to allow them to be designed
3283 independently and reused.
3284 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3285 Renamed from catch_body, catch_handler, and uncaught_throw; made
3287 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3289 (scm_catch): Use the above.
3290 (scm_throw): Don't bother printing a message for an uncaught
3291 throw; we establish a default handler in init.
3292 * throw.h (scm_internal_catch): Prototype updated.
3293 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3295 (struct scm_body_thunk_data): New structure, used as data
3296 argument to scm_body_thunk.
3297 * init.c (struct main_func_closure): New structure, packaging up
3298 the data to pass to the user's main function.
3299 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3300 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3301 scm_internal_catch to establish a catch-all handler, using
3302 scm_handle_by_message. This replaces the special-case code in
3304 (invoke_main_func): Body function for scm_internal_catch; invoke
3305 the user's main function, using the main_func_closure pointer to
3306 decide what to pass it.
3307 * root.c (struct cwdr_body_data): Remove handler_proc member.
3308 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3309 (cwdr_handler): Removed.
3311 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3313 * socket.h (SCM_P): update bind prototype.
3314 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3315 include "feature.h".
3316 (scm_socket): return a port, not a file descriptor object.
3317 include "fports.h" and <unistd.h>
3318 (scm_bind): take a port, not a file descriptor object.
3319 take an extra argument for address args.
3321 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3322 INADDR_NONE, INADDR_LOOPBACK.
3324 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3326 * init.c: include net_db.h and not fdsocket.h.
3327 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3329 * Makefile.am: corresponding changes.
3330 * socket.h: renamed from fdsocket.h, fix names.
3331 * net_db.h: renamed from socket.h, fix names.
3332 * socket.c: renamed from fdsocket.c.
3333 remove _sys from procedure names.
3334 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3335 add "socket" to features list.
3336 * net_db.c: renamed from socket.c.
3337 remove _sys from procedure names.
3338 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3339 add "net-db" to features list.
3340 include "net_db.h". don't include <sys/socket.h> or
3343 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3345 * tags.h (scm_tags): Removed comma at end of last enumerator.
3347 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3349 Don't use GCC extensions to allocate space for debugging frames.
3350 (Here he goes again! Why do we put up with this?!)
3351 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3352 an scm_debug_info structure, not an in-line array of them. Add
3353 'info' member, to say how many vect elements we've used, for eval
3355 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3356 a new variable debug_info_end to mark the end of vect, instead of
3357 the address of the 'info' pointer itself.
3358 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3359 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3360 (SCM_APPLY): Explicitly allocate space for debug.vect.
3361 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3362 * stacks.c: Adjusted for new debug frame structure.
3363 (RELOC_INFO, RELOC_FRAME): New macros.
3364 (stack_depth, read_frames): Use them, and new scm_debug_frame
3365 element 'info', instead of magically knowing that eval frames have
3366 an info pointer sitting after vect.
3367 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3369 (scm_init_stacks): Formatting tweaks.
3371 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3373 Give GCC more control flow information, so it can be sure that
3374 variables aren't used uninitialized.
3375 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3376 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3377 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3378 scm_misc_error): Tell GCC that these functions never return.
3379 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3380 out the field type, call abort if SCM_ASSERT returns, to placate
3382 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3383 scm_wta ever returns. We can't handle this case anyway, and this
3384 gives the optimizer more information.
3385 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3386 scm_wta ever returns.
3388 In some cases, the code is fine, but GCC isn't smart enough to
3389 figure that out; this usually happens when one variable is only
3390 initialized and used when a particular condition holds true, and
3391 we know that condition will never change within a given invocation
3392 of the function. In this case, we simply initialize the variables
3393 to placate the compiler, hopefully to a value which will cause a
3394 crash if it is ever actually used.
3395 * print.c (scm_iprin1): Initialize mw_pos.
3396 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3397 * throw.c (scm_ithrow): Initialize dynpair.
3398 * unif.c (scm_uniform_vector_ref): Initialize cra.
3399 * struct.c (init_struct): Initialize prot.
3400 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3402 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3403 if EXPR contains no expressions.
3405 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3407 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3408 cause an infinite loop (???). So much for the algebraic
3409 equivalency of variable-sized arrays and alloca...
3411 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3413 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3414 a SCM boolean, not a C boolean.
3416 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3418 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3419 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3420 rules for raising scm_mtrigger. Previously, unfortunate but not
3421 unlikely circumstances could result in almost constant invokation
3422 of the gc. Now, this situations should be less likely, but they
3423 are not prevented completely.
3425 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3427 * numbers.c (scm_fuck): Procedure removed; looks like old test
3429 * numbers.h: Prototype removed.
3431 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3433 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3434 array to a pointer, to match my Nov 21 change in eval.c.
3436 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3438 * libguile.h: Added #include "libguile/backtrace.h", #include
3439 "libguile/stacks.h".
3441 * strings.c (scm_string scm_make_string scm_string_ref
3442 scm_string_set_x scm_string_equal_p scm_string_append):
3443 Bugfix according to scm patch from Aubrey Jaffer:
3444 Corrected long-standing
3445 (not (eqv? (integer->char 128)
3446 (string-ref (make-string 1 (integer->char 128)) 0)))
3447 bug found by John Kozak <jk@noontide.demon.co.uk>.
3449 * strports.c, strports.h: Make scm_eval_0str return the value of
3450 the last expression evaluated (previously, it returned void).
3452 * strports.c, strports.h: New function: scm_read_0str. Does what
3455 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3457 * simpos.c (scm_getenv): return #f if string can't be found in the
3458 environment instead of throwing an exception, for compatibility
3459 with numerous other systems.
3461 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3463 * Makefile.am (.c.x): Use guile-snarf.
3464 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3466 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3468 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3470 * backtrace.c (scm_display_error_message): Made non-static, and
3471 renamed from display_error_message.
3472 * backtrace.h (scm_display_error_message): Added extern decl.
3473 * throw.c (uncaught_throw): Use it to display the error message.
3475 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3477 * inet_aton.c: Use #if 0, not #ifdef 0.
3479 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3481 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3482 to convert the returned value.
3483 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3484 the offset argument.
3486 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3488 Add new interface to catch/throw, usable from C as well as
3490 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3491 (scm_internal_catch): New function, replaces...
3492 (scm_catch_apply): Deleted.
3493 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3494 mechanism which is a bit more code, but can be used nicely from C
3495 and implement the Scheme semantics as well.
3496 (scm_internal_catch): This is the replacement; it's named after
3497 the analogous function in Emacs.
3498 (scm_catch): Reimplemented in terms of the above.
3499 (struct catch_body_data, catch_body, catch_handler): New
3500 functions, used by scm_catch.
3501 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3502 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3503 support for new cwdr.
3505 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3508 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3510 * acconfig.h: Added DYNAMIC_LINKING symbol.
3511 * configure.in: Add option and checks for dynamic linking.
3512 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3513 dynl.h: New files for dynamic linking support.
3514 * Makefile.am (libguile_a_SOURCES):
3516 (modinclude_HEADERS): Added "dynl.h".
3517 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3519 * init.c (scm_boot_guile_1): Call
3520 scm_init_dynamic_linking to initialize dynamic linking support.
3522 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3524 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3525 (as we Schemers say). It needs to be global, so that I can tweak
3526 it for the proper operation of unexec.
3527 (scm_boot_guile_1_live): New variable, see above.
3529 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3531 * guile-snarf.sh: Removed.
3532 * PLUGIN/guile.libs: Added dependency for -lm.
3533 * acinclude.m4: Renamed from aclocal.m4.
3534 * PLUGIN/greet: Removed.
3535 * Makefile.am, aclocal.m4: New files.
3536 * configure.in: Updated for Automake.
3538 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3540 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3541 and not top_level_lookup_thunk_var.
3543 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3545 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3547 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3549 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3550 Scheme function, instead of syntax. Single argument is now a
3553 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3555 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3556 scm_ra_divide): Properly terminate statements passed as arguments
3557 to IVDEP macros. (Thanks to Bernard Urban.)
3559 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
3560 with non-constant sizes. (Thanks to Bernard Urban.)
3562 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3564 It's an "eval closure", not an "eval thunk." A thunk is a
3565 function of no arguments.
3566 * root.h (struct scm_root_state): Renamed
3567 top_level_lookup_closure_var from top_level_lookup_thunk_var.
3568 (scm_top_level_lookup_closure_var): Renamed from
3569 scm_top_level_lookup_thunk_var.
3570 * root.c (mark_root): Uses changed.
3571 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
3572 * init.c (scm_start_stack): Uses changed.
3573 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
3574 Change scheme-visible name to *top-level-lookup-closure* from
3575 *top-level-lookup-thunk*.
3577 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
3579 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
3580 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
3582 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
3584 * gc.c (struct scm_heap_seg_data): Doc fixes.
3586 * gc.c (scm_gc_sweep): Empty all segments' freelists before
3587 sweeping. Then, prepend each segment's free cells to its
3588 freelist, rather than wiping out the old value. (Thanks to Marius
3591 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
3592 scm_check_freelist, scm_debug_newcell): New functions and
3593 variables, for debugging freelist problems.
3594 * pairs.h (SCM_NEWCELL): New debugging version added.
3595 * gc.h (scm_debug_newcell): Added extern declaration, used by
3596 debugging version of SCM_NEWCELL.
3598 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3600 On some systems <libc.h> conflicts with <unistd.h>, and should not
3601 be #included at all.
3602 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
3603 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
3604 * configure.in: Call it.
3605 * posix.c, filesys.c: Use its results to decide whether or not to
3607 * configure, scmconfig.h.in: Rebuilt with autoconf and
3610 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3612 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
3613 pointer to the stdio stream before calling scm_setbuf0, so the
3614 latter will be able to retrieve it. I'm surprised this didn't
3615 segfault earlier. (Thanks to Christopher Lee.)
3617 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3619 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
3622 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3624 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
3625 number of stack narrowing specifier pairs. The first specifier in
3626 a pair controls inner border, the second the outer border. A
3627 number means cut that number of frames, a procedure object means
3628 cut until that object is found in operator position in a frame.
3630 * root.c (cwdr): Bugfix.
3632 * read.c: Recording of positions disabled by default.
3634 * procs.c (scm_closure_p): New function.
3636 * posix.c (scm_tmpnam): New function.
3638 * load.c: Added #include "throw.h".
3639 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
3642 * load.c, load.h (scm_read_and_eval_x): New function.
3644 * eval.c: Renamed debug option "deval" to "debug".
3646 (scm_eval_x): `eval!' is no longer accessible from the scheme
3647 level. Motivation: We can't allow operations which introduce
3648 glocs into the scheme level. Guile's type system can't handle
3649 these as data. Use `eval' or `read-and-eval!' as replacement.
3651 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
3652 SCM_CONSP since this is a macro!; Set vframe.prev to
3653 scm_last_debug_frame instead of 0. In this way we can look
3654 "above" the virtual start stack frame if we wish.
3655 (scm_debug_hang): New function: Useful for debugging Guile in
3656 certain tricky situations. Will probably be removed later...
3658 * debug.h: Changed semantics of debug option "backtrace". This
3659 option now only indicates whether we want automatic backtrace at
3662 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3664 * ports.c: #include "filesys.h"
3665 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
3667 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
3668 Motivation: This is system specific code which is related to file
3669 I/O. It also may use select. Added code by Gary Houston to
3670 detect presence of character in stdio buffers.
3672 * libguile.h: #include "libguile/libpath.h"
3674 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
3675 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
3676 SCM_SITE_DIR; Install libpath.h among the other include files.
3678 * load.c, load.h (scm_sys_package_data_dir): New function.
3680 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3682 * stacks.h: Bugfix: Don't use tail-array length field as stack
3683 length field! This screwed GC.
3685 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3687 * _scm.h: Added #ifndef around definition of macros min and max.
3689 * __scm.h: Added hooks for threads to plugin to in ints protection
3690 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
3691 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
3692 the main code in these macros duplicated and spread over multiple
3693 files. Renamed SCM_THREADS_SWITCHING_CODE ->
3694 SCM_THREAD_SWITCHING_CODE.
3696 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
3698 * snarf.h: New file.
3699 * guile-snarf.sh: New file.
3700 * Makefile.in (inner_h_files): Added snarf.h
3701 (ancillary, install, uninstall, distclean): Added actions for
3703 (.c.x): Use guile-snarf.
3704 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
3705 (gen_c_files): Note that these depend on guile-snarf.
3706 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
3707 now in "snarf.h". Added #include "snarf.h" to get them.
3708 * libguile.h: Added #include "snarf.h".
3709 (Patches applied and tweaked by Jim Blandy.)
3711 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3713 * socket.c: Use K&R style declaration for 'close'; the GNU coding
3714 standards suggest against providing prototypes for system
3715 functions. Thanks to Greg Troxel.
3717 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3719 * strports.c (scm_eval_0str): New function.
3720 #include "read.h", to get prototype for scm_read.
3721 * Makefile.in (strports.o): Update dependencies.
3722 * strports.h: New prototype.
3724 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
3725 scheme name from "int?" to "integer?". It seems to do the job.
3726 * numbers.h: Rename prototype too.
3727 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
3730 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
3731 scm_num_eq_p): Rename these according to R4RS conventions: call
3732 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
3733 to making libguile R4RS compliant without ice-9...
3735 * load.c (scm_sys_search_load_path): Search for files under all
3736 extensions listed in the %load-extensions variable. If FILENAME
3737 is absolute, return it unchanged, without searching the load path.
3738 (scm_loc_load_extensions): New variable, pointing to
3739 %load-extensions' value cell.
3740 (scm_init_load): Initialize it, and the value it points to.
3741 (scm_primitive_load_path): Improve error reporting.
3743 * load.c (scm_loc_load_hook): New variable, pointing to value cell
3744 of new Scheme variable %load-hook.
3745 (scm_primitive_load): Apply %load-hook to filename.
3747 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
3749 * configure.in: add tests for figuring out whether buffered data
3750 is available in a FILE structure, which is needed by char-ready.
3752 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
3755 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
3756 exceptions using misc_error instead of syserror. It seems a bit
3757 odd to throw an exception if a string can't be found in the
3758 environment, but it's consistent with open-file, stat etc.
3759 (simpos.h): remove sys_ from getenv.
3761 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
3762 occurs, throw an error instead of returning errno. Return value
3764 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
3766 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
3768 * filesys.c (scm_stat2scm): derive file type and permissions from
3769 the stat mode and append them to the returned vector.
3770 There isn't much overhead in doing this and it avoids the need to
3771 work with S_IRUSR et al. in Scheme.
3772 Define symbols scm_sym_regular etc.
3773 (scm_init_filesys): don't intern S_IRUSR etc.
3775 * load.c: change s_try_load and s_try_load_path to s_primitive_load
3776 and s_primitive_load_path.
3778 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
3780 * error.h: don't declare error symbols. prototype for scm_misc_error.
3782 * stackchk.c (scm_stack_overflow_key): defined here instead of in
3785 * error.c: use SCM_SYMBOL to set up error keys.
3786 scm_misc_error: new procedure.
3788 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3790 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
3791 between `#!' and `!#' is ignored.
3792 (skip_scsh_block_comment): New function.
3794 * feature.c (scm_set_program_arguments): New argument, FIRST.
3795 * feature.h: Update prototype.
3796 * init.c (scm_boot_guile_1): Pass new argument to
3797 scm_set_program_arguments.
3799 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3801 * init.c (scm_start_stack): Don't initialize scm_progargs here.
3802 (scm_boot_guile): Call scm_set_program_arguments here, later than
3803 the old initialization.
3805 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
3806 initialization procedure.
3807 - Delete in, out, err arguments; there are other perfectly good
3808 ways to override these when desired.
3809 - Delete result argument; this function shouldn't ever return.
3810 - Rename init_func argument to main_func, for less confusion.
3811 - Delete boot_cmd argument; main_func is more general.
3812 -Add 'closure' argument, to help people pass data to main_func
3813 without resorting to global variables.
3814 - Abort if reentered; don't bother returning an error code.
3815 - Call scm_init_standard_ports to set up the default/current
3816 standard ports; no need to pass them to scm_start_stack.
3817 - Remove code to evaluate the boot_cmd, and start the repl; let
3818 the user do something like that in main_func if they want.
3819 - Remove code to package up a return value; main_func can do any
3821 - Call exit (0), instead of returning.
3822 (scm_start_stack): Don't initialize the I/O ports here; that's
3823 weird. Delete in, out, err arguments. Move guts to
3824 scm_init_standard_ports, scm_stdio_to_port.
3825 (scm_init_standard_ports): New function, to set up current and
3826 default standard ports.
3827 (scm_start_stack, scm_restart_stack): Make these static.
3828 * init.h (scm_boot_guile): Adjust declaration.
3829 (scm_start_stack, scm_restart_stack): Remove externally
3830 visible declarations for these.
3831 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
3833 * fports.c (scm_stdio_to_port): New function. Its guts used to be
3834 written out several times in scm_start_stack.
3835 * fports.h: New declaration for the above.
3837 * feature.c (scm_set_program_arguments): New function.
3838 * feature.h: New declaration for the above.
3840 * ports.c: Formatting tweak.
3842 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
3844 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
3845 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
3846 for obtaining the address of a car or cdr field. Motivation:
3847 &SCM_CXR make assumptions about the internal structure of the
3850 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
3851 Motivation: see SCM_CXRLOC.
3853 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
3854 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
3855 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
3856 Motivation: Safer use. Some other macros are defined in terms of
3857 these operations. If these are defined using the SCM_SETCXR
3858 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
3859 to inefficiency and an <e1> with side-effects could potentially
3860 break. Also, these particular operations are heavily utilized in
3861 the garbage collector. In unoptimized code there will be a
3864 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
3865 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
3866 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
3867 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
3868 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
3869 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
3870 vports.c: Cleaned up use of pairs: Don't make any special
3871 assumptions about the internal structure of selectors and
3872 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
3873 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
3874 (Among other things, this change makes it easier to build Guile
3875 with certain compilers which have problems with casted lvalues.)
3877 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3879 * stacks.c: Improve selection of relevant stack frames when making
3880 a stack object. Introduce one level of indirection in the stack
3881 object to make it possible to "narrow" to a certain region of the
3882 stack. This facilitates making use of more clever algorithms (not
3883 implemented) for selecting relevant frames and gives a cleaner
3884 design since selection of frames can be done independently of
3885 extraction of frames from the real stack.
3886 (scm_stack_id): Also take #t as argument which means look at
3889 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
3890 Turn n_tail into an integer directly representing current number
3891 of frames in stack. Add field tail.
3893 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
3895 * debug.c (scm_make_memoized): Made it available at scheme level.
3896 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
3897 SCM_NIMP before applying heavier predicates in argument checking.
3898 (scm_local_eval): Also take memoized object as argument.
3900 * backtrace.c (scm_display_error): Just a safety measure: Stacks
3901 aren't created with zero length, but should such a strange
3902 creature suddenly turn up...
3904 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
3906 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
3907 `del', for the sake of C++ compilers. (Patch applied by JimB.)
3909 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
3911 * variable.c (scm_make_variable): Make the name hint optional, as
3913 (anonymous_variable_sym): Renamed from variable_sym. All uses
3916 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
3917 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
3918 of scm_primitive_load_path was also changed to
3919 "primitive-load-path", from "%try-load-path". Callers changed.
3920 We'd like to respect the convention that a function named
3921 "try-mumble" should behave just like the function called "mumble",
3922 but return #f instead of signalling some error.
3923 * load.h: Rename prototypes.
3925 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3927 * print.c (make_print_state, grow_print_state), print.h: Modified
3928 the print state representation: Don't use a tail array for
3929 recording of circular references. Resizing of the print state
3930 structure invalidates the print state pointer. To avoid passing
3931 around an indirect print state reference to all printing
3932 functions, we instead let the print state reference a resizable
3935 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3937 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
3938 Don't crash when passed an improper list terminated by a
3939 non-immediate value.
3941 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
3943 Allocate data for structures on an eight-byte boundary, as
3944 required by the tagging system.
3945 * struct.c (alloc_struct): New function.
3946 (scm_make_struct, scm_make_vtable_vtable): Call it.
3947 * struct.h (scm_struct_n_extra_words): Bump to 3.
3948 (scm_struct_i_ptr): New "field".
3949 * gc.c (scm_gc_sweep): When we need to free the data, use the
3950 information stored by alloc_struct to find the beginning of the
3951 block allocated to the structure, so we can free it.
3953 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3955 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
3958 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
3959 (scm_debug_info): New member: id.
3961 * stacks.c: Stacks are now represented as structs; Stacks have an
3962 id given to them by `start-stack'.
3963 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
3965 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
3966 Changed stack representation.
3968 * debug.c (scm_procedure_name): Try procedure property `name' for
3969 compiled closures aswell.
3971 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
3973 * eval.c: scm_i_name moved to gsubr.c
3974 (scm_m_define): Record names of all kinds of procedure
3975 objects. (Earlier, only closures were recorded.)
3977 * procprop.h: Added declaration of scm_i_name.
3979 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
3980 (scm_make_gsubr): Record names of compiled closures.
3982 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3984 * debug.c, debug.h: Removed obsolete code.
3986 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
3987 stacks.c: Renamed regs --> scm_contregs.
3989 * print.c (scm_free_print_state): Cleanup print state before
3990 returning it to pool. It is better to do it here than in
3991 scm_prin1 since scm_prin1 is called often.
3993 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
3994 s_set_source_property_x): Check that first argument is a pair or a
3997 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
3998 scm_i_line, scm_i_column and scm_i_breakpoint global.
4000 * init.c: Added #include "backtrace.h" and #include "stacks.h".
4001 (scm_boot_guile_1): Added calls to scm_init_backtrace and
4004 * debug.h: Added debug object smob declaration and macro
4007 * configure.in: Build with backtrace.o and stacks.o if debug
4010 * Makefile.in: Added entries for new files: backtrace.c,
4011 backtrace.h, stacks.c and stacks.h.
4013 * symbols.c (scm_sym2ovcell): Fixed documentation.
4015 * _scm.h (min, max): Added.
4017 * async.c: Moved `min' macro to _scm.h.
4019 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
4020 SCM_BACKTRACE_INDENT.
4022 * eval.c: Added new debug options `maxdepth' and `indent'.
4024 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
4026 * print.h: Added selector SCM_PRINT_STATE.
4028 * print.c: New functions: scm_make_print_state,
4029 scm_free_print_state.
4031 * print.h: Added declarations for scm_make_print_state,
4032 scm_free_print_state.
4034 * debug.c (scm_m_start_stack): New acro.
4036 * debug.h: Small cleanup.
4038 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4041 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

4061 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
4062 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
4063 declare functions with prototypes. (Patch thanks to Marius
4066 More prototype-related changes from Marius Vollmer:
4067 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4068 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4069 * ports.h (ptobfuns): Added prototypes. This means some casting in
4071 * fports.c: Added casts for initializations, since the functions
4072 are defined to take FILE * as their stream argument, not SCM.
4073 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4074 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4075 to `char *str_data' to conform to prototype.
4077 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4079 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4081 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4083 * stime.c, stime.h: use SCM_P method.
4085 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4087 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4088 be given at least two arguments. Insist that lst's last element
4089 be a list, but don't make any requirements of its predecessors.
4091 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4093 * eval.c (scm_nconc2last): Revert last change; there seems to be
4094 other stuff going on here.
4096 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4098 * eval.c (scm_nconc2last): Make sure that each element of lst
4099 (which is a list of argument lists, except for the tail) is a
4100 proper list, i.e., finite and terminated by '().
4102 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4104 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4107 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4108 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4111 * vectors.c (scm_make_vector): Fill vectors with the undefined
4112 value, to help make Guile Scheme code more portable to other
4115 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4116 * symbols.h, tags.h: Doc fixes.
4118 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4120 * async.c (scm_take_signal): Doc fixes.
4122 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4124 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4125 want to subtract it from the modulus; we just want to leave it
4128 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4130 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4133 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4135 * throw.c (scm_catch_apply): Finished implementation of
4138 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4140 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4142 (scm_init_filesys): set "i/o-extensions" feature.
4145 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4147 * Makefile.in (root.o): Correct dependencies.
4149 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4151 * Makefile.in: Added dependency entry for root.o.
4153 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4154 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4156 * init.c (scm_start_stack): Set initial root continuation number
4159 * procs.c: New function: scm_thunk_p.
4161 * procs.h: Added declarations of scm_thunk_p.
4163 * root.c: Renamed `call-with-new-root' -->
4164 `call-with-dynamic-root'.
4165 (cwdr): Removed allocation of new root state. This should be done
4166 separately by use of scm_make_root.
4167 (scm_apply_with_dynamic_root): New function: Does what it
4168 sounds like. Needed when spawning threads.
4170 * root.h: Added member last_debug_frame to root state.
4171 Added #include "libguile/debug.h"
4173 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4174 arguments. The motivation is that code in root.c needs catch
4175 functionality, and we want to avoid code duplication.
4176 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4177 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4178 handlers that run without popping the stack into the dynwind
4181 * throw.h: Added prototypes for scm_catch_apply and
4184 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4186 * root.h (scm_root, scm_set_root): Decouple thread support details
4187 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4188 SCM_SET_THREAD_LOCAL_DATA.
4190 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4191 and tortoise scanning loop.
4193 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4195 * Makefile.in: Rebuild dependencies.
4197 * libguile.h: #include "libguile/print.h" before "smob.h", since
4198 the latter uses the print_state structure.
4200 * throw.c (scm_ithrow): Use the correct variable when checking to
4201 see if a given element of scm_dynwinds is a valid catch.
4203 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4204 structure, abort; don't just silently ignore the garbage.
4206 * _scm.h: #include "print.h" here, since it seems to be used just
4208 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4209 strports.c, unif.h: Don't #include "print.h".
4211 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4213 * feature.h (scm_loc_features): Removed external declaration.
4214 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4216 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4218 * feature.c (scm_init_feature): Added threads feature (needs to be
4219 initialized here, since features doesn't exist when
4220 scm_init_threads is called).
4222 * libguile.h: Added #include "libguile/../threads/threads.h".
4223 (This is a kludge to get thread support working. This should be
4226 * configure.in, acconfig.h: Added flags for thread support.
4228 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4231 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4232 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4235 * _scm.h: Added conditional #include "threads.h"
4237 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4238 SCM_THREADS_SWITCHING_CODE.
4240 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4241 allocate the basic dynamic root object.
4242 (scm_boot_guile): Added call to scm_init_root.
4244 * root.c, root.h: Added root smob.
4245 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4246 functions: Implements dynamic roots mostly according to spec in
4247 SCM manual. Main difference is that the second argument is a
4248 throw handler rather than an error "thunk".
4250 * root.h: Added declaration of scm_init_root.
4252 * root.c: Added #include "genio.h", #include "smob.h", #include
4253 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4255 (scm_init_root): Added #include "root.x".
4257 * throw.c: Added #include "stackchk.h"
4258 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4259 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4260 can be used in scm_call_with_new_root; Added reenabling of stack
4261 checking when catching a throw.
4263 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4265 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4267 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4268 element is not found, as per R4RS.
4270 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4272 * list.c: Doc fixes throughout.
4274 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4276 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4277 declare the char * to be const. Avoids a warning in rgx.c.
4279 * ports.h: spelling fix.
4281 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4284 * load.c (scm_sys_try_load_path): throw an error if file not found
4285 (like it says it in NEWS).
4287 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4289 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4290 PROPS slot to '(), not #f; it's an empty alist.
4292 * throw.h, throw.c: Use SCM_P instead of #if hair.
4294 Remove special support for uncaught throws; see throw.c for
4296 * throw.c (uncaught_throw): New function.
4297 (scm_ithrow): Call uncaught_throw if we don't find a throw
4298 target; don't mess with scm_bad_throw_vcell.
4299 (scm_bad_throw_vcell): Variable deleted.
4300 (scm_init_throw): Don't initialize it.
4302 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4305 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4307 * numbers.c (scm_istr2int): If the number is short (as most
4308 numbers are), just call scm_small_istr2int to deal with it.
4309 (scm_small_istr2int): New function, created by un-#ifdefing the
4310 non-bignum version of scm_istr2int and renaming it.
4312 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4314 * load.c (scm_sys_try_load): don't check whether value returned
4315 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4316 Change the Scheme name from %try-load to primitive-load.
4318 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4319 Can avoid passing a message, allowing it to be derived in the
4320 error handler (e.g., if we want to throw to the key both from
4323 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4325 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4326 references now have a new appearance which is more compact and
4327 also gives a clue about what the target of the reference is.
4328 By setting parameters in the print state, more fancy printing can
4329 be achieved. This is used by the (not yet commited) backtrace
4332 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4334 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4337 * print.c: Added #include "struct.h". Removed function
4340 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4341 scm_iprin1. Removed prototype for scm_prlist.
4343 * arbiters.c (prinarb),
4344 async.c (print_async),
4345 debug.c (prindebugobj, prinmemoized),
4346 eval.c (prinprom, prinmacro),
4347 filesys.c (scm_fd_print, scm_dir_print),
4349 mallocs.c (prinmalloc),
4350 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4351 smob.h (scm_smobfuns),
4352 srcprop.c (prinsrcprops),
4354 unif.c, unif.h (scm_raprin1, rapr1),
4355 variable.c (prin_var): Changed argument `int writing' to
4356 `scm_print_state *pstate'.
4358 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4359 that it will be called before scm_init_print.
4361 * print.c (scm_prin1): Print states are now allocated when calling
4362 scm_prin1 and then passed around to all printing functions as an
4363 argument. A cache `print_state_pool' enables reuse of print
4365 (scm_make_print_state): New function.
4366 (scm_iprin1): Adaption to print states.
4367 (scm_iprlist): An initial "hare and tortoise" scan brings down
4368 time complexity to O (depth * N). (Better time complexity will be
4369 achieved when the printing code is completely rewritten.)
4371 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4373 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4374 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4375 it gets done whether or not the cache variable has a value.
4377 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4379 Distinguish #f and ().
4380 * __scm.h: #undef SICP.
4381 * pairs.h (SCM_EOL): Delete this definition, equating it with
4383 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4384 the value it used to have. Doc fixes, too.
4386 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4388 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4389 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4390 Lord's implementation of structs, allowing for tail arrays as
4391 described in the manual. Also fixed some bugs. (Both the interface
4392 and the implementation should be improved.)
4394 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4396 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4397 People who whish to see the source can do `(print-enable 'source)'.
4398 Removed #ifdef DEBUG_EXTENSIONS.
4400 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4402 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4403 integer (assuming for now accepting an integer is a good thing).
4405 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4406 %S will be used instead for write'ing arguments.
4408 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4409 asserts. fix a few other asserts.
4410 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4411 scm_uniform_vector_ref, scm_array_set_x,
4412 scm_dimensions_to_unform_array): change args in
4413 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4414 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4415 scm_substring_fill_x): likewise.
4416 gsubr.c (scm_gsubr_apply): likewise.
4417 eval.c (SCM_APPLY): likewise.
4419 * eval.c (4 places): replace scm_everr with lgh_error or
4422 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4423 scm_memory_error): new procedures.
4424 scm_everr: deleted. can use scm_wta, dropping first two args.
4425 scm_error: convert NULL subr to SCM_BOOL_F.
4427 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4430 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4433 * error.c, error.h: new error keys: scm_arg_type_key,
4434 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4436 scm_wta: reimplement using lgh_error instead of scm_everr.
4438 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4440 * gdbint.c: scm_lread now has one more argument.
4442 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4443 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4444 loading source from non-file ports, which, e. g., happens when
4445 using the Emacs interface).
4447 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4450 * read.c: Added code for recording of positions of source code
4451 expressions; New functions: recsexpr, scm_lreadrecparen;
4452 _scm_make_srcprops --> scm_make_srcprops
4453 (scm_flush_ws): Removed updating of positions counters. This work
4454 is already done by scm_gen_getc
4456 * read.h: Added prototype for scm_lreadrecparen
4458 * print.c: Added #include "alist.h"
4460 * eval.c: Added #include "hash.h"
4462 * eq.c: Added #include "ramap.h"
4464 * options.c: Documentation fixes.
4466 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4467 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4468 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4469 --> scm_make_srcprops
4471 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4472 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4473 function calls in the definition of the whash access macros.
4475 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4477 * init.c (scm_boot_guile): Add level of indirection to
4478 scm_boot_guile_1() to ensure that stack base pointer is properly
4479 initialized. There was no guarantee that variable i was the
4480 highest/lowest variable on stack (i.e. the call frame of
4481 scm_boot_guile was not completely protected from gc).
4483 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4485 * ports.h (scm_port_table): put back file_name, it will be used to
4486 support debugging. Undo related changes in fports.c, ioext.c,
4489 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4491 * ports.h (scm_port_table): remove file_name member for now, it seems
4493 * fports.c (scm_open_file): don't set file_name in PTAB.
4494 (prinfport): don't use file_name in PTAB.
4495 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4496 * ports.c (scm_add_to_port_table): don't intialize file_name.
4497 (scm_port_file_name): remove for now.
4498 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4500 * fports.h (scm_mkfile): prototype deleted.
4501 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4503 * debug.c, unif.c: use scm_out_of_range instead of
4504 wta for range errors (ASSERT still needs work).
4506 * error.c, error.h (scm_out_of_range): new procedure.
4508 * error.c, error.h (scm_out_of_range_key): new key.
4510 * posix.c (scm_sync): #else was missing.
4512 * error.c, error.h: append _key to names scm_num_overflow and
4515 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4516 of consing an empty list.
4517 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4518 of macros, saves code and string space.
4519 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4520 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4521 lower case. Rename scm_syserror_m to scm_syserror_msg.
4522 error.h: prototypes for new procedures.
4524 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4526 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4528 * error.c, error.h: setup scm_num_overflow key.
4530 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4531 Remove definition of SCM_OVSCM_FLOW.
4533 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4535 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4536 explicit message and args.
4538 * error.c, error.h, __scm.h: change system_error_sym to
4541 * error.c (system_error_sym): remove leading %% from the Scheme name
4544 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4546 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4548 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4549 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4550 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4551 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4552 renamed. (These were introduced by unsupervised name
4555 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4557 * print.c: Added code for detection of circular references during
4558 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4559 a hook for printing of closures (accessible via print options).
4560 This leads to a split of calls to scm_iprin1 into two classes:
4561 elementary print operations (e. g. the code which prints a smob)
4562 still use scm_iprin1 while top level calls (like scm_display) use
4563 scm_prin1. scm_prin1 begins by clearing the data structure used
4564 to record reference information.
4566 * print.h: Added declarations of scm_prin1 and scm_prlist.
4568 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
4570 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
4572 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
4574 * error.c (err_head): scm_iprin1 --> scm_prin1
4576 * debug.c: Adjusted header comment.
4580 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4582 * strerror.c: Doc fix.
4584 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4586 * gdbint.c (gdb_read): Now possible to run during GC.
4587 (unmark_port, remark_port): New functions.
4589 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
4591 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
4592 of allocating a new string object. Also, increase size by
4593 the factor 2 instead of 1.5.
4595 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
4597 * __scm.h (SCM_P): Corrected to run under traditional C.
4599 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
4602 * async.c: Calls to scm_sysintern corrected.
4604 * async.h (scm_async_clock): Redundant declaration removed.
4606 * continuations.c (scm_dynthrow): Redundant declaration removed.
4608 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
4609 Definition typos corrected.
4611 * debug.h: Missing declarations of functions in debug.c added
4614 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
4615 Missing declarations to functions in eval.c added.
4617 * filesys.c: Possibly uninitialized variable rv.
4619 * gc.h (scm_object_addr, scm_unhash_name): Missing
4620 declarations of functions defined in gc.c added.
4622 * genio.c: Possible typos str_data -> wstr_data. ???
4624 * genio.c: Possibly unintended shadowing of local variable
4625 `int c' (gotos out of scope of inner `c'). ???
4627 * init.c: Uninitialized `SCM last' may be used.
4629 * ioext.h: (scm_sys_isatty_p): Typo.
4631 * list.h (scm_list_head): Missing prototype for function in
4634 * numbers.c (scm_two_doubles): Changed from extern to static
4635 (is used only within numbers.c).
4637 * numbers.h: Repeated declarations removed.
4639 * ports.h (scm_close_all_ports_except): Declaration for the
4640 function defined in ports.c added.
4642 * posix.h: Missing declarations added.
4644 * procs.h (scm_make_subr_opt): Missing declaration added.
4646 * socket.h (scm_sys_gethost): Missing declaration added.
4648 * socket.h: Redundant declarations removed (they are in fdsocket.h).
4650 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
4651 Missing declarations added.
4653 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
4655 * struct.c: Uninitialized variable `SCM answer' may be used.
4657 * unif.c (l2ra): Declaration prototype.
4659 * unif.c (scm_array_equal_p): Dummy definition removed (it is
4660 defined in ramap.c).
4662 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
4663 Redundant declarations removed (they are in ramap.h).
4665 * variable.h (scm_make_udvariable,
4666 scm_make_undefined_variable): Declaration corrected to
4667 correspond variable.c.
4669 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
4670 Missing declarations added.
4672 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
4674 * Makefile.in (distclean): Don't forget to delete fd.h.
4676 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4678 * fd.h.in, tags.h: Trivial cleanups.
4680 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
4681 marksweep.h just declared functions from gc.c.
4682 * gc.h, libguile.h: Don't #include "marksweep.h".
4683 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4684 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
4685 dependencies updated.
4687 * libguile.h: Don't #include "files.h"; it's been deleted.
4689 * files.c (scm_sys_delete_file): Moved to filesys.c.
4690 File is now empty; deleted.
4692 * filesys.c: scm_sys_delete_file is now here. Remove
4693 #if's; they seem to rely on remnants of an old portability
4694 regimen. If the problems come up again, solve them properly,
4695 using autoconf. Specifically: Don't test M_SYSV, and #define
4696 remove to be unlink if it's #defined; don't use remove just
4697 because HAVE_STDC_HEADERS is #defined.
4698 * filesys.h: Add declarations for scm_sys_delete_file.
4699 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4700 files.o, files.h, files.c, and files.x.
4701 * init.c: Don't #include "files.h", and don't call scm_init_files.
4703 Use SCM_P instead of PROTO; the latter intrudes on the user's
4705 * params.h: Deleted; definition of SCM_P moved to...
4706 * __scm.h: ... here, where it replaces PROTO macro.
4707 * libguile.h, smob.h: Don't #include "params.h".
4708 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
4709 smob.h: Fix prototypes accordingly.
4710 * Makefile.in: Update dependencies.
4711 (inner_h_files): Remove params.h.
4713 * gc.c: #include "gc.h"; every module should include its header,
4714 to let the compiler cross-check the declarations against the
4717 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
4718 simpos.h: #include "libguile/__scm.h".
4720 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
4722 * init.c: Don't forget to #include smob.h and init.h.
4723 * Makefile.in: Dependencies updated.
4725 * smob.h: Use PROTO instead of #if __STDC__.
4727 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
4729 * __scm.h: Doc fixes.
4731 * __scm.h, libguile.h: Use "quotes" in the #includes, not
4732 <angles>; this allows `make depends' to work properly.
4734 * libguile.h: #include smob.h and pairs.h before the others; they
4735 define typedefs used by other headers.
4737 C files should #include only the header files they need, not
4738 libguile.h (which #includes all the header files); the pointless
4739 recompilation was wasting my time.
4740 * Makefile.in (all .o dependency lists): Regenerated.
4741 * libguile.h: Don't try to get a definition for size_t here...
4742 * __scm.h: Do it here.
4743 * _scm.h: Since this is the internal libguile header, put things
4744 here that all (or a majority) of the libguile files will want.
4745 Don't #include <libguile.h> here; that generates dependencies on
4746 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
4747 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
4748 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

4845 * weaks.c: Get "weaks.h".
4847 * stackchk.h: #include "libguile/debug.h",
4849 * print.h, read.h: #include "options.h", since everyone who uses
4850 either of these files will need that.
4852 * smob.h: #include "ports.h", "genio.h", and "print.h", since
4853 anyone who uses this file will need them to define the smob
4854 printing functions. Also, get markers.h, since people will need
4855 to #define the mark functions.
4857 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
4858 * ports.h: ... to here.
4860 * ports.h (scm_port_table_size): Explicitly give type as 'int';
4861 don't rely on archaic C default type rules.
4863 * fports.h: #include "libguile/ports.h", since you need that in
4864 order to parse this.
4866 * genio.h: #include "libguile/print.h", because you need that to
4867 parse this; don't bother #including "ports.h", since print.h gets
4870 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
4872 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
4873 this; it's now a reference to an element of *scm_root.
4875 * debug.h: Don't #include "options.h"; the compiler won't be able
4876 to find that once the headers are installed; instead, #include
4877 "libguile/options.h".
4878 * gc.h: Same, with marksweep.h.
4879 * mbstrings.h: Same, with symbols.h.
4880 * scmhob.h: Same, with _scm.h.
4881 * smob.h: Same, with params.h.
4883 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
4884 C files; there's no need for this, and it forces recompilations
4887 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
4889 * error.c (scm_error): declare scm_error_callback.
4891 * error.h: prototype for scm_error_callback.
4893 * __scm.h: define lgh_error.
4894 (SCM_SYSERROR): redefine using lgh_error.
4896 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
4898 * error.c (scm_error): new procedure.
4900 * error.h: prototype for scm_error.
4902 * Makefile.in (install): install scmconfig.h from the current
4903 directory, not $(srcdir).
4905 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4907 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
4908 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
4909 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
4910 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
4911 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
4912 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
4913 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
4914 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
4915 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
4916 vports.h, weaks.h: #include "libguile/__scm.h", not
4917 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
4918 dependencies are within libguile properly.
4920 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4922 * Makefile.in (.c.x): Simplify; there's no need to run this rule
4923 when scmconfig.h doesn't exist.
4925 * load.c (scm_sys_try_load): Correct spelling.
4927 * feature.c (scm_loc_features): Make this static.
4929 * Makefile.in (libpath.h): Omit trailing slash from path. We
4930 shouldn't require it of users, so why put it here?
4932 Move code to initialize and search %load-path from ice-9 to C
4933 code, so we can use the load-path to find the ice-9 boot code;
4934 this makes it easier to run Guile without installing it. See
4935 corresponding changes in guile/Makefile.in.
4936 * feature.c: Move stuff concerned with the load path to load.c.
4937 (scm_compiled_library_path): Deleted.
4938 Don't #include libpath.h here.
4939 * feature.h: Don't mention scm_compiled_library_path.
4940 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
4941 <sys/stat.h>, and <unistd.h> (if present).
4942 (R_OK): #define if the system hasn't deigned to.
4943 (scm_loc_load_path): New variable.
4944 (scm_init_load_path, scm_sys_search_load_path,
4945 scm_sys_try_load_path): New functions.
4946 (scm_init_load): Initialize scm_loc_load_path to point to the
4947 value cell of the Scheme %load-path variable.
4948 * load.h: Add declarations for scm_sys_search_load_path,
4949 scm_sys_try_load_path.
4950 * init.c: Call scm_init_load_path.
4951 * Makefile.in (feature.o, load.o): Dependencies updated.
4953 * load.c, load.h: Rewrite using PROTO macro.
4955 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4957 * gc.c (scm_cellp): New function: C predicate to determine if an
4958 SCM value can be regarded as a pointer to a cell on the heap.
4960 * gc.h: Added declaration of scm_cellp.
4962 * gdb_interface.h: New file: The GDB interface header from the GDB
4965 * gdbint.c: New file: GDB interface.
4967 * gdbint.h: New file: GDB interface.
4969 * libguile.h: Added #include <libguile/gdbint.h>.
4971 * init.c (scm_boot_guile): Added scm_init_gdbint.
4973 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
4974 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
4975 found if object files and source are kept separate).
4977 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
4979 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
4981 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
4983 * configure.in: Don't substitute the values of TCL_SRC_DIR and
4984 TK_SRC_DIR; they're not relevant any more.
4986 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
4987 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
4989 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
4991 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
4992 search path, so we can find the <libguile/MUMBLE.h> headers.
4994 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
4996 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
4997 implicit in the .c.o rule.
4998 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
5001 Put the library path in a header file, instead of passing it on
5002 the command line in every compilation.
5003 * Makefile.in (libpath.h): New target.
5004 (feature.o): Depend on libpath.h.
5005 (clean): Delete libpath.h.
5006 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
5007 * feature.c: ... #include "libpath.h" here.
5008 * .cvsignore: Ignore libpath.h.
5010 Don't install the unwashed masses of Guile header files in the
5011 main #include path; put most of them in a subdirectory called
5012 'libguile'. This avoids naming conflicts between Guile header
5013 files and system header files (of which there were a few).
5014 * Makefile.in (pkgincludedir): Deleted.
5015 (innerincludedir): New variable; this and $(includedir) are enough.
5016 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
5017 (installed_h_files): Divide this up. Now this variable lists
5018 those header files which should go into $(includedir) (i.e. appear
5019 directly in the #include path), and ...
5020 (inner_h_files): ... this new variable says which files appear in
5021 a subdirectory, and are referred to as <libguile/mumble.h>.
5022 (h_files): List them both.
5023 (install): Create innerincludedir, not pkgincludedir. Put
5024 the installed_h_files and inner_h_files in their proper places.
5025 (uninstall): Corresponding changes.
5026 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5027 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5028 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5029 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5030 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5031 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5032 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5033 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5034 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5035 vports.h, weaks.h: Find __scm.h in its new location.
5036 * __scm.h: Find scmconfig.h and tags.h in their new locations
5037 (they're both "inner" files).
5039 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5041 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5043 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5045 * posix.c: Doc fixes.
5047 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5049 * socket.c: Don't include a prototype for inet_aton; just use a
5050 K&R style declaration, to avoid warnings but minimize the chance
5051 of conflicts with the system.
5053 On NextStep, <utime.h> doesn't define struct utime, unless we
5054 #define _POSIX_SOURCE before #including it.
5055 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5056 * acconfig.h: New comment text for above CPP symbol.
5057 * configure.in: Call it.
5058 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5060 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5062 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5063 testing for __EMX__.
5065 * posix.c: #include <libc.h>, if it exists.
5067 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5068 don't even know if the latter exists.
5070 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5071 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5072 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5074 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5076 (scm_init_posix): Use them when initializing the Scheme constants
5079 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5081 * Makefile.in (libdir, includedir, bindir): Use the
5082 autoconf-supplied values, instead of deriving them ourselves.
5083 (pkgincludedir, datadir, pkgdatadir): New variables.
5084 (install, uninstall): Put the header files in a special
5085 subdirectory, not in the main search path.
5087 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5088 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5090 * Makefile.in (IMPLPATH): Deleted; never used.
5092 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5093 on the Tcl/Tk source any more.
5094 (INCLUDE_CFLAGS): Remove references to the above.
5096 * Makefile.in (version.o): Corrected dependencies.
5098 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5100 * libguile.h: #include "version.h"
5102 * init.c (scm_boot_guile): Call scm_init_version.
5103 * gscm.c (gscm_run_scm): Call scm_init_version.
5105 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5106 GUILE_VERSION): AC_DEFINE these.
5107 (acconfig.h): #undef the above symbols.
5109 * Makefile.in (libobjs): Add version.o.
5110 (installed_h_files): Add version.h.
5111 (c_files): Add version.c.
5112 (gen_c_files): Add version.x.
5113 (version.o): New rule.
5114 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5115 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

5123 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5124 weaks.o): Add version.h to dependency lists.
5125 (markers.o): Remove duplicate rule.
5127 * version.h: New file.
5129 * version.c: New file.
5131 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5133 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5134 array; use it appropriately. Since GCC is quite happy to
5135 subscript functions, it never warned us about this; we should use
5136 -Wpointer-arith in the future. I guess we never tested
5139 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5141 * socket.c: Doc and copyright fixes.
5143 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5145 * debug.c: Fixed and improved gdb support.
5147 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5149 * socket.c: Added declaration of inet_aton to avoid compiler
5150 warning. (Hope this solution is correct.)
5152 * stime.c: Added declaration of ftime. (This is missing in
5155 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5157 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5159 * Makefile.in (c_files): add strerror.c.
5161 * strerror.c: new file from Emacs' sysdep.c.
5162 maybe configure should also check for sys_errlist.
5164 * configure.in (AC_REPLACE_FUNCS): add strerror.
5166 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5168 * debug.c (scm_init_debug): Added initialization for
5169 scm_evaluator_traps.
5171 * debug.h, debug.c: Various name changes.
5172 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5173 "debug-options-interface". See commentary in options.c.
5175 * options.h, options.c: Options now have documentation strings.
5176 Also added a long explanatory commentary.
5178 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5181 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5182 last_debug_info_frame is now updated in all cases.
5184 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5187 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5189 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5190 Added option STACK_CHECKING.
5192 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5194 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5196 * __scm.h: Removed symbols for debugging support.
5198 * acconfig.h: Added symbols for debugging support.
5200 * configure.in: Added user option for debugging support.
5201 --enable-debug will include the debugging code into libguile.a.
5203 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5204 scm_relocate_chunk_to_heap.
5206 * debug.c: New file: low-level debugging support. It also
5207 includes support for debugging with gdb. (The extensions to gdb
5208 are written by Per Bothner at Cygnus.)
5210 * debug.h: New file: low-level debugging support.
5212 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5213 argument pairs. Extensive modifications to the debugging
5214 evaluator. Added "SECTION:" commentaries to clarify what happens
5215 when, during double compilation. Renamed EVALIMP --> EVALIM.
5216 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5217 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5218 the beginning of the file. New procedure: scm_unmemocopy.
5219 Added some global state variables needed by the debugging
5220 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5221 check_entry, check_apply, check_exit, debug_options and
5222 evaluator_traps. New acro: undefine.
5224 * eval.h: Renamed EVAL --> XEVAL.
5226 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5227 --> scm_make_weak_key_hash_table.
5229 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5230 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5232 * libguile.h: Conditionally include debug.h
5234 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5235 scm_object_properties shouldn't return handle. `handle' now gets
5236 initialized in scm_set_object_properties_x. scm_object_properties
5237 doesn't any longer create an entry in scm_object_whash.
5239 * options.c: New file: handling of run time options.
5241 * options.h: New file: handling of run time options.
5243 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5245 * print.c: New procedure: scm_print_options
5247 * print.h: Defines for print options.
5249 * read.c: New procedure: scm_read_options
5251 * read.h: Defines for reader options.
5253 * root.h: Added scm_source_whash among scm_sys_protects.
5255 * srcprop.c: New file: source properties.
5257 * srcprop.h: New file: source properties.
5259 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5260 (Bug found by A. Green.)
5262 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5264 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5266 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5268 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5270 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5271 and should be called by the final client.
5273 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5275 * gc.h: Use the PROTO macro when declaring functions.
5276 * gc.c: Use the PROTO macro when declaring static functions.
5277 Remove the CPP hair around function definitions.
5279 * gc.c (scm_init_storage): Initialize scm_asyncs.
5281 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5282 preprocessor symbol; "__scm.h" is where it might get #defined.
5283 * __scm.h: Similar: #include <scmconfig.h> before testing
5286 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5288 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5290 * init.c (scm_boot_guile): Add init_func argument; call
5291 (*init_func) instead of calling scm_appinit; it's ucky to
5292 hard-code names for the user's procedures.
5293 * init.h (scm_boot_guile): Adjust declaration.
5295 * __scm.h (PROTO): New macro, for declaring functions with
5298 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5299 eliminate all the __STDC__ conditionals.
5300 (scm_boot_guile): Add declaration.
5301 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5302 Remove __STDC__ conditionals around function definitions; the
5303 declarations in init.h will provide the same information, more
5306 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5307 complain about it in the error message; the error message is
5308 adequate without that note, and there's nothing the user can do
5311 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5313 * Makefile.in (ancillary): Drop def.sed.
5315 * posix.c (scm_init_posix): Use numeric values, rather than
5316 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5317 F_OK. The symbols aren't available on some systems, and I'm
5318 pretty sure their values are fixed by common widespread practice.
5319 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5321 More functions unavailable on some systems.
5322 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5323 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5325 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5326 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5327 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5328 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5329 stub that signals an error as the #else.
5331 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5333 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
5335 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
5337 * unif.c: include ramap.h.
5339 * read.c (endif): case_insensative_p renamed case_insensitive_p.

5345 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
5347 * configure.in: check for sys/ioctl.h.
5349 * ports.c: include <malloc.h> not "malloc.h".
5351 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5353 * fports.c: remove ttyname and tmpnam declarations.
5355 * posix.c: fewer ttyname declarations.
5357 * fports.c: include <string.h> not "string.h".
5359 * init.c, ioext.c: include string.h and unistd.h.
5361 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
5363 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
5364 genio.c, simpos.c, vports.c: include string.h.
5366 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
5368 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
5370 (scm_addr_buffer_size): change type from scm_sizet to int.
5371 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5372 from scm_sizet to int.
5374 * error.c: include unistd.h.
5376 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5379 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5381 * __scm.hd, def.sed: deleted.
5383 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5385 Changes for NeXT, suggested by Robert Brown.
5386 * configure.in: Call AC_TYPE_MODE_T.
5387 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
5388 NeXT. Put header file list in alphabetical order.
5389 * configure, scmconfig.h.in: Regenerated.
5390 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
5392 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
5395 * acconfig.h: New file, providing documentation for the CPP
5396 symbols defined in configure.in
5397 * acconfig-1.5.h: Removed; superceded by the above.
5399 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
5401 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
5403 * fports.c (scm_open_file): don't return #f, throw error.
5405 * ioext.c (fileno): renamed from %fileno.
5406 (soft-fileno): deleted.
5408 * ports.c (scm_port_revealed): don't need to check for -1 from
5410 (scm_set_port_revealed_x): return unspecified, not #f.
5412 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
5414 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5416 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5418 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
5420 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5422 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5423 This is necessary on Ultrix, and doesn't hurt portability.
5425 * Makefile.in (dist-dir): New target, implementing a new dist system.
5426 (installed_h_files): Put in alphabetical order.
5427 Remove duplicate entries for markers.h and unif.h.
5428 (c_files): Remove duplicate entries for markers.c.
5429 (ancillary): Renamed from anillery; all uses changed. Remove
5430 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5431 Remove all the ../doc/* files; doc/Makefile.in handles that.
5433 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5435 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5436 every if must have an else, or else the whole command has a
5437 non-zero exit code whenever the if's condition is false.
5439 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
5441 * posix.c: include string.h.
5443 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
5445 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
5448 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
5449 Remove leading % from scheme names.
5450 Do not return error values, call SCM_SYSERROR or similar.
5452 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
5454 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
5456 * struct.c (scm_init_struct): new file.
5458 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
5460 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
5461 (scm_list_head): added list-head for rapidly chopping argument
5462 lists off of longer lists (and similar).

5466 * objprop.c (scm_object_property): assq the cdr of the whash
5467 handle for obj, not the handle itself.
5469 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
5471 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
5472 weak hash tables last of all marking to avoid an obscure gc bug.
5473 WARNING: circular lists stored in a weak hash table will hose us.
5475 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
5477 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
5478 new functions similar to scm_substring_move_left_x and
5479 scm_substring_move_right_x.
5481 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
5483 * init.c (scm_boot_guile): prevent gc with scm_block_gc not

5488 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
5490 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
5492 * strports.c (scm_strprint_obj): convenience function. C for
5493 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
5495 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
5496 removed to a separate library
5498 * init.c (scm_boot_guile): copied from guile-tcl.c.
5499 Initialization specific to tcl interpreters removed.
5501 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
5503 * ports.c (scm_ports_prehistory): size malloced here doesn't
5504 matter so long as it is non-0 (got rid of "* 4").
5506 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
5508 * gscm.h: gscm_mkarray eliminated (presumably was not being used
5509 since its definition was bogus).
5511 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
5513 * mallocs.[ch]: back again (for rx at least).
5515 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
5517 * ports.c: removed functions relating to the mapping between ports
5518 and descriptors. (That stuff is unix-specific and should be collected
5519 in a separate library).
5521 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
5522 (Tom Mckay@avanticorp.com)
5524 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
5526 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
5527 handled correctly (SCM_FREEP was applied to them) -- test for
5528 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
5529 being overwritten with #f. (brown@grettir.bibliotech.com)
5531 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
5533 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

5536 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
5538 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak

5548 Generalized assoc and hash-table functions.
5549 Factored pairs.c into multiple files.

5561 NOTE: don't use a alist here.
5562 (scm_set_procedure_properties_x): fix type checking throughout this file.

5572 * vports.c (scm_make_soft_port): allocate a port table entry
5573 (possibly triggering gc) before setting the tag of the corresponding
5576 * pairs.c (scm_delq_x): never throw an error.
5578 * vectors.c (scm_make_vector): made the default vector fill argument
5579 into '() (much more useful than the previous value, "#unspecified")
5581 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
5583 * ports.c (scm_add_to_port_table): Added fields
5584 to port table entries: file_name, line_num, col.
5585 Update these in open_file, gen_getc and gen_ungetc.
5586 Added procedures to access those fields.
5588 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
5590 * procs.c (scm_make_subr_opt): new entry point for making

5609 GC statistics keeping moved to gc.c.
5610 Other statistics keeping can be done from Scheme.
5611 REPLS are now written in Scheme.

5620 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
5622 * feature.c (scm_compiled_library_path): moved here from repl.c.
5623 This file is for stuff relating specifically to Scheme libraries
5626 * eval.c (scm_m_define): don't give warning about redefinition, don't
5629 NOTE: this should throw a resumable exception with parameters --
5630 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
5632 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
5634 * error.c: scm_warn eliminated.

5653 * strports.c: don't reveal the port's string to the caller
5654 because it changes size.
5656 (stputc stwrite): check/change the strings length with interrupts
5659 * objprop.c (scm_set_object_property_x &c): use the generic
5660 hashing functions and be threadsafe.

5663 (per suggestion jaffer@gnu.ai.mit.edu).
5665 * mbstrings.c (scm_multi_byte_string): guard against argument list
5668 * strings.c (scm_make_string): loop cleanup

5696 initialization to fix a race condition.
5698 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
5699 object, not in a global.
5700 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)

5719 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
5721 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
5722 set the multi_byte flag correctly in symbols. This is wrong.
5723 intern_obbary_soft and msymbolize should take an extra parameter.
5724 Also, weird multibyte symbols don't print correctly.
5725 The weird symbol syntax is also a bit bogus (emacs doesn't quite
5728 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
5730 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
5731 use the system symhash. == #t means create an uninterned symbol.
5733 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
5735 * strings.c (scm_make_shared_substring): build'em.
5736 It might better to keep a table of these and use one
5737 less cons-pair per shared-substring.

5807 * lvectors.c (scm_get_lvector_hook):
5808 In guile-ii, the lvector code was broken. It was fixed in guile-iii.
5809 It seems to me like if it is broken again in guile-iv...Here is a patch.
5810 "! || (LENGTH (keyvec) == 0))"
5811 (From: Mikael Djurfeldt <mdj@nada.kth.se>)
5814 * gscm.c (gscm_sys_default_verbosity):
5815 incorrectly declared for non-__STDC__
5816 (Tom_Mckay@avanticorp.com)
5818 * ports.c (scm_setfileno): Tweak the macro a bit
5819 to make it easier to port to systems that use
5820 more than a single structure field to hold a descriptor.
5822 * debug.c (change_mode): Avoid GNUCism "int foo[n];"
5823 Give a warning, not an error, for unrecognized modes.
5825 * eval.c (SCM_CEVAL):
5826 static char scm_s_for_each[];
