3 Changes to avoid signed/unsigned comparison warnings.
4 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
5 (scm_gc_sweep): Make n and j local to the blocks they're used in,
6 so they can have appropriate types for each application. Make i
7 signed. Use initializers in some spots. I'll probably pay for
9 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
10 (scm_must_realloc): Make nm unsigned.
11 (init_heap_seg): Make new_seg_index and n_new_objects signed.
12 (scm_init_storage): Use prototype-style definition, and make the
14 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
15 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
17 * filesys.c (scm_readlink): Make local vars rv and size ints, to
18 avoid signed/unsigned comparison warnings, and because the return
19 value of readlink may be -1. Don't bother casting the third
22 * filesys.c (scm_dirname, scm_basename): Move these to their own
23 page, at the end of the file.
24 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
26 * eval.h (scm_eval_options_interface): Add external prototype for this.
27 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
29 * eval.c (scm_lookupcar1): Make this static.
31 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
32 Make these prototype declarations, not K&R-style.
34 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
35 unsigned comparison warning.
37 * appinit.c: File removed. It had a single function in it, empty,
38 whose reason for existence is explained in no documentation or
39 comment. I think it's there as a default for some Tcl-style
40 initialization, but Tcl abandoned that approach a while ago.
41 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
42 (BUILT_SOURCES): Remove appinit.x.
43 * Makefile.in: Regenerated.
45 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
47 * Makefile.in: Regenerated using the last public version of
48 automake, not the hacked Cygnus version.
50 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
53 * Makefile.in, scmconfig.h.in: Regenerated.
54 * init.c, readline.c: Don't check if TOTORO is #defined.
56 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
58 * Makefile.am: Adjust for new thread configuration system.
59 (INCLUDES): Include the value of THREAD_CPPFLAGS.
60 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
62 (THREAD_LIBS): Definition deleted; automake will generate such
64 * Makefile.in: Regenerated.
66 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
68 Simplify smob and port marking; set the mark bit in the generic
69 marking code, and make marker routines only responsible for
70 turning up outgoing pointers.
71 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
72 before calling the marking function. Don't call the marking
73 function if it's zero.
74 * markers.c (scm_mark0): Just return #f. This function isn't
75 necessary at all now, but it's harmless to call it. We'll leave
76 it in so other folks' code doesn't croak at link time.
77 (scm_markcdr): Don't call SCM_SETGC8MARK.
78 * async.c (mark_async): Don't call SCM_SETGC8MARK.
79 * dynl.c (mark_dynl_obj): Same.
80 * root.c (mark_root): Same.
81 * srcprop.c (marksrcprops): Same.
82 * unif.c (markra): Same.
83 * variable.c (scm_markvar): Same.
84 * ports.c (scm_markstream): Same.
85 (void_port_ptob): Specify zero for our marking function.
86 * debug.c (debugobjsmob): Same.
87 * dynwind.c (guardsmob): Same.
88 * filesys.c (dir_smob): Same.
89 * fluids.c (fluid_smob): Same.
90 * fports.c (scm_fptob, scm_pipob): Same.
91 * mallocs.c (mallocsmob): Same.
92 * regex-posix.c (regex_t_smob): Same.
93 * smob.c (freecell, flob, bigob): Same.
94 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
95 * throw.c (jbsmob, lazy_catch_funs): Same.
97 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
99 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
100 scm_copy_tree on code in order not to let memoized code to leak
101 out. Thus, scm_copy_tree needs to copy vectors as well since
102 quasiquote can introduce evaluated code also inside vector
105 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
107 * eval.c (scm_copy_tree): Removed ability to copy vectors.
109 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
110 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
113 * unif.c: Say that ivect and uvect are of type signed and unsigned
114 long instead of int in commentary so that it correctly describes
117 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
119 * stime.c: Removed declaration of strptime. (It should be
120 declared by the system headers. If it turns out that some systems
121 don't, we'll handle that then.) (Thanks to Greg Troxel.)
123 * stime.h: Renamed TIMEH --> STIMEH
125 * backtrace.c (scm_display_error, scm_display_backtrace): In order
126 to increase portability, don't use structure assignment.
127 (Thanks to Nicolas Neuss.)
129 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
131 (finalize_fd_sets): Added empty statement after last case label.
132 (Thanks to Nicolas Neuss.)
134 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
137 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
139 * init.c, readline.c: OK, I won't have these readline.x bug
140 reports anymore. We've had them since April. The current reason
141 is a completely unintelligible failure of totoro.red-bean.com to
142 do the test for rl_getc_function in libreadline correctly. This
143 kludge overrides the test if we're on totoro so that the snapshot
144 generation process can work.
146 * readline.c: Define a strdup replacement if not existent on system.
148 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
150 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
151 This change makes scm_make_vector R5RS compatible. We cannot keep
152 the third argument since people want to be able to deduce the form
153 of the C function call only by looking at R5RS. (At the same time
154 we have removed some unnecessary complexity!)
156 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
157 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
158 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
159 argument in call to scm_make_vector.
161 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
163 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
164 This macro is useful in applications.
166 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
168 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
169 (scm_parse_path, scm_search_path): New Scheme level procedures.
171 * load.h (scm_internal_parse_path, scm_parse_path,
172 scm_search_path): Declared.
174 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
176 * filesys.c (dirname, basename): New procedures.
178 * init.c (scm_boot_guile_1): Removed condition around
181 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
182 new data type (guards) for representation of C level guards and
183 data on the wind chain.
184 (scm_internal_dynamic_wind): New function.
186 * dynwind.h: Declare scm_internal_dynamic_wind.
188 * root.h (scm_root_state): Added scm_cur_loadp.
190 * root.c (mark_root): Added comment about cur_loadp.
192 * load.c: #include "dynwind.h";
193 (scm_primitive_load): Use scm_inner_dynamic_wind to update
196 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
198 * ports.c (current-load-port): New procedure.
200 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
202 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
203 not a tty, return #f.
205 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
206 to Julian Satchell and Roland Kaufmann.)
208 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
209 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
211 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
213 * debug.h, debug.c (scm_start_stack): New function. Implements
214 the guts of old scm_m_start_stack.
216 * debug.c (scm_m_start_stack): Use scm_start_stack.
218 * init.c (scm_start_stack, scm_restart_stack): Renamed to
219 start_stack and restart_stack. (These have static scope.)
221 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
223 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
224 readline functions to come in release 2.3. (Thanks to Chet
226 (handle_errors): Use the above functions.
228 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
230 * readline.c: Improvements for readline support: Handle errors
231 better; Implement before-read-hook.
233 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
235 * init.c (scm_boot_guile_1), readline.c: Test for
236 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
237 assure that we have version >= 2.1.)
239 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
241 * readline.c (scm_add_history): Bugfix: Do strdup before giving
242 away the string to add_history.
243 (completion_function): Do completion for readline. (Thanks to
245 (scm_filename_completion_function): New procedure: Filename
247 (current_input_getc): New function. Use this one instead of
248 standard getc from readline.
250 * throw.c, throw.h (scm_handle_by_throw): New function: This
251 handler throws errors to next handler on the dynwind chain.
253 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
255 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
258 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
260 * procprop.c (scm_i_procedure_arity): New function. Returns arity
262 (scm_procedure_properties): Modified to return arity together with
264 (scm_procedure_property): Added the read-only property `arity'.
265 (scm_set_procedure_property_x): It is an error to set the `arity'
268 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
269 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
271 * procprop.h (scm_sym_arity): New symbol.
273 * objects.c (scm_set_object_procedure_x): New procedure: Use this
274 to set the dispatch procedure of an operator or entity object.
276 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
277 Made procedure slots read-only.
279 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
280 scm_tcs_cons_gloc case in zero args switch; Fixed args
281 construction for operators in scm_tcs_cons_gloc case in two args
284 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
286 * fluids.c: Removed use of assert.h (in order to avoid
289 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
291 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
293 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
294 change makes the evaluator safer at the cost of evaluation speed.
295 It handles the case when the user has added a non-immediate
296 improper end of the application form, e.g., `(+ 0 . x)'.
297 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
298 minimize the extra cost as much as possible. The new code is
299 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
300 problem with structs planted directly in the code (e.g. by a
301 macro). This no longer causes segmentation fault. (Thanks to
304 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
305 arg `proc' in order to be able to throw errors; New argument
308 * Removed extra #include "debug.h"
310 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
312 * scmsigs.c: Declare usleep as returning void on some systems.
313 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
316 * coop.c (usleep): Return void on some systems.
318 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
320 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
322 * coop.c: Changed return type of usleep to int.
324 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
325 isn't found in the OS.
327 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
328 isn't enabled. (Thought that I had made this change ages ago...)
330 * iselect.c: Declare bzero if not defined by OS.
332 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
334 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
335 condition. (Thanks to John Tobey.)
337 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
338 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
341 * __scm.h: Start the long-term project of moving to POSIX threads.
342 Phase 1: Classification of all critical sections.
343 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
344 for A sections. (See comments in __scm.h for details.)
346 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
347 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
349 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
351 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
352 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
353 (libpath.h, versiondat.h): Replaced dependency on Makefile with
354 dependencies on $(srcdir)/Makefile.in
355 $(top_builddir)/config.status in order to avoid circularity.
357 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
358 from argc if argc was 0 initially.
360 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
361 in generation of libpath.h.
363 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
365 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
366 libguile from 2 to 3.
368 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
370 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
372 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
374 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
375 scm_set_port_column_x, scm_port_filename,
376 scm_set_port_filename_x): Removed optional arguments. Added
377 proper argument checking.
379 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
380 stack size in machine words.
382 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
383 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
384 to Ole Myren Röhne.)
386 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
388 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
389 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
391 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
394 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
395 procedure apply: Copy argument lists before pushing them unto the
396 environment so that the environment won't get mutated due to
397 manipulation of procedure arguments. This should perhaps be
398 regarded as a temporary solution until someone finds a more
399 efficient one. (Thanks to Maciej Stachowiak.)
401 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
403 * script.c (scm_compile_shell_switches): Use "guile" as default
404 zero arg if argc is NULL.
406 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
408 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
409 is zero. (Thanks to Dirk Herrmann.)
411 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
413 * ports.c (scm_add_to_port_table): First line is now line 0
414 (was 1). (Interface changed according to suggestion by Per
417 * backtrace.c (display_header): Add 1 to line and column numbers
418 when presenting them to the user.
420 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
421 from debug.c --> eval.c
423 * eval.h, eval.c (scm_eval_options_interface): New options
425 (SCM_EVAL_STACK): New option: Size of newly created stacks,
426 i.e. stacks for new threads.
428 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
430 * eval.c (unsafe_setjmp): Removed with #if 0.
432 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
435 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
436 to avoid compiler warnings.
438 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
440 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
442 * throw.c (handler_message): Print message on current error port
443 instead of default error port. (Thanks to Maciej Stachowiak.)
445 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
447 * ports.c (scm_add_to_port_table): allocate in units of
448 struct scm_port_table *, not struct scm_port_table.
449 * posix.c (scm_close_pipe): remove the port from the port table
451 Thanks to Rob Engle for both fixes.
453 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
455 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
456 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
458 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
460 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
462 * backtrace.c (display_error_body, display_backtrace_body),
463 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
464 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
465 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
466 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
469 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
470 don't receive the jmpbuf arg anylonger.
471 (scm_catch): Don't accept a #f tag.
472 (scm_throw): Check that key is a symbol.
473 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
475 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
477 * async.c (async_pending): Removed declaration.
479 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
481 * dynwind.c (scm_wind_chain): New debug function.
483 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
484 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
485 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
486 extra layer of functions around the body and handler of a thread.
487 This extra layer makes sure that the handler is called in the
488 dynamic context of the surround (= empty dynwind list), but under
489 the *dynamic root* of the body. We can not use the dynamic root
490 of the surround since that root belongs to another thread => stack
491 is not handled correctly. It may seem ugly to use this extra
492 layer, but the extra cost in terms of execution time is really
493 negligible compared to the total amount of time required to create
494 a thread, and it would reduce maintainability to duplicate the
495 crucial and complicated steps performed by cwdr.
497 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
498 (SCM_ALLOW_INTS): Added thread switching code before interrupts
499 get re-enabled. The important effect of this is that interrupts
500 are blocked during thread switching so that thread data structures
501 don't risk getting messed up by an unfortunate signal.
502 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
503 seems to do more aggressive optimization which actually move
504 instructions around in these macros in a fatal way. Therefore:
505 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
506 just superstitious...)
507 (SCM_TICK): Maybe do a context switch and take care of asyncs.
508 This macro should be used instead of SCM_ASYNC_TICK since the
509 latter doesn't do context switches any more.
511 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
512 instead of SCM_ASYNC_TICK.
514 * coop.c, iselect.c: Since thread switches are now performed with
515 interrupts masked, we can't use the old mechanism of delivering
516 signals immediately when they arrive. Signals must instead be
517 delivered when the asyncs run *after* the end of the critical
518 section in scm_internal_select. But this also means after context
519 switch so that the signal will be delivered to a different thread.
520 To avoid this, I have changed the protocol of
521 coop_wait_for_runnable_thread and friends so that they are allowed
522 to return the original thread. So, if a signal arrives during
523 scm_internal_select, we won't any longer be forced do a context
524 switch, but can remain in the same thread and deliver the signal
527 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
528 scm_asyncs_pending and made it global.
530 * iselect.c: Small fixes.
532 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
533 coop_condition_variable_init, coop_condition_variable_wait,
534 coop_condition_variable_signal): Changed return type from `void'
535 to `int'. This is to adhere closer to the pthreads interface.
536 This, in turn, is part of an attempt to provide C versions of the
537 mutex and condition variable primitives which can be part of a
538 frontend to COOP or pthreads.
540 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
541 coop_condition_variable_destroy): New functions.
543 * coop-threads.c (scm_wait_condition_variable): Use
544 coop_condition_variable_wait_mutex.
546 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
547 Definitions moved to coop-defs.h.
549 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
550 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
551 scm_cond_destroy): New C interface to mutecis and cond vars.
553 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
555 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
557 * iselect.c: Now several threads can wait on the same file
558 descriptor. The behaviour is compatible with OS select: All
559 threads waiting for the fd return with the same status.
561 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
563 * coop-threads.c, threads.h (scm_spawn_thread): New function.
564 Can spawn a thread from application C code.
566 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
568 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
569 gh_doubles2scm): New functions.
571 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
573 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
574 commented-out version of gh_eval_str()
576 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
578 * socket.c (scm_bind): free soka after use.
580 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
582 * stime.c (tzvar): new variable.
583 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
584 avoid memory leaks when allocating.
586 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
588 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
591 * gc.c, tags.h: Doc fixes.
593 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
595 * eval.c (macro-eval!): Removed. This function was a design bug.
596 It allowed memoized code to leak out to the scheme level. Most
597 things that you could do with `macro-eval!' can be done with
600 1997-12-20 Tim Pierce <twp@skepsis.com>
602 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
603 scm_fgets now depends on ftell(3) to know how many bytes were
606 1997-12-15 Tim Pierce <twp@skepsis.com>
608 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
609 dealing with strings.
611 1997-12-13 Tim Pierce <twp@skepsis.com>
613 Make %read-line more suitable for implementing read-line efficiently.
614 * ioext.c (scm_read_line): Strip the terminating newline from a
615 string, and return a cons of the string and its terminator.
617 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
618 of the string that is read is stored in this memory location.
619 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
620 * genio.c, genio.h (scm_do_read_line): Update caller.
621 * ports.h (scm_ptobfuns): Update typedef.
622 * fports.c (scm_fptob, scm_pipob): Update struct.
624 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
626 * filesys.c (set_element): Return file descriptor.
627 (fill_select_type): Return the highest file descriptor.
628 (scm_select): Tell select about the highest file descriptor. On
629 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
630 Therefore the extra overhead for calculating the maximum fd seems
631 to be more than compensated. Is this correct? In any case,
632 scm_internal_select will be much faster with this info.
633 (scm_select, fill_select_type, set_element): Don't accept any kind
634 of object in the file descriptor list or vector.
636 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
638 * iselect.c (finalize_fd_sets): Bugfix.
640 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
642 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
643 when using scm_internal_select (since we might switch to another
646 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
648 * simpos.c (scm_system): always define: use sysmissing if not
649 available. Check for HAVE_SYSTEM instead of _Windows (does
650 Windows lack system or does it have an unusable one?).
651 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
652 Let the argument be optional: if not supplied, call system(NULL).
654 * ports.c (scm_close_port): relax the type check from OPPORTP to
655 PORTP; closing a closed port is allowed.
657 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
659 * fports.c (scm_fgets): Return if the last char in a chunk is
660 newline. When fgets returns a string whose length is `size-1', it
661 is ambiguous whether a whole line was retrieved, so we must check
662 explicitly whether a line terminator is present.
664 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
666 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
667 before taking the CDR. (Thanks to Harald Meland.)
669 * filesys.c (scm_stat): Slightly optimized.
671 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
673 * ports.c (scm_close_port): Make sure the port is open before
676 * guile-snarf.in: Pass args through to gcc in a way that preserves
677 whitespace boundaries. (Thanks to Greg Badros.)
679 1997-12-02 Tim Pierce <twp@skepsis.com>
681 * stacks.c (scm_frame_procedure): Reverse the logic in the return
682 statement. (Thanks to Doug Evans for pointing this out.)
684 1997-12-01 Tim Pierce <twp@skepsis.com>
686 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
688 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
690 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
691 errno macro expansion of this field name. (errno is a C
692 preprocessor macro on some systems.)
694 1997-11-29 Tim Pierce <twp@skepsis.com>
696 * iselect.c: Doc fix.
698 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
700 * init.c (scm_start_stack): Removed initialization of
701 scm_the_last_stack_var.
703 * backtrace.h: Declare scm_the_last_stack_var.
705 * backtrace.c: Define scm_the_last_stack_var.
707 * root.c (mark_root): Don't mark the_last_stack_var.
709 * root.h (scm_root_state): Removed the_last_stack_var.
711 * throw.c: Added #include "fluids.h"
712 (ss_handler): `the-last-stack' is now a fluid.
714 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
715 --> the_last_stack_fluid.
717 * backtrace.c: Added #include "fluids.h"
718 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
719 (scm_backtrace): `the-last-stack' is now a fluid.
721 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
722 after scm_init_fluids.
724 1997-11-28 Tim Pierce <twp@skepsis.com>
726 * iselect.c: #ifdef USE_THREADS around thread-related includes.
728 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
729 DLSYM_ADDS_USCORE to decide whether to add an underscore.
731 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
733 * iselect.c (coop_next_runnable_thread,
734 coop_wait_for_runnable_thread): Disable interrupts so that no
735 async is executed before a potential error_revive.
736 (scm_internal_select): Disable interrupts during the parts of the
737 code which manipulate the sleep queue and the file descriptors.
739 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
741 * Makefile.am: Added iselect.c and iselect.h.
743 * coop.c (coop_qinit): Initialize fields used by
745 (coop_qget, coop_qget, coop_tmp_queue): Made global.
746 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
747 replacement in iselect.c.
748 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
749 coop_join): If GUILE_ISELECT enabled, use
750 coop_wait_for_runnable_thread instead of
751 coop_next_runnable_thread.
752 (usleep, sleep): New replacements for system functions if
753 GUILE_ISELECT is enabled.
755 * coop-threads.h: Declare coop_wait_for_runnable_thread.
757 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
759 * filesys.c: Added #include "iselect.h". Moved FD-macros to
760 iselect.h. Implement Scheme level `select' using
761 scm_internal_select. (See NEWS.)
763 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
765 * init.c: Call scm_init_iselect.
767 * iselect.h, iselect.c: New files. Implements
768 scm_internal_select. (See NEWS.)
770 1997-11-27 Tim Pierce <twp@skepsis.com>
772 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
773 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
774 and scm_must_free, since ultimately the string returned will be copied
775 by scm_makfrom0str anyway. Also, read any characters that may have
776 been pushed onto the port with scm_ungetc.
777 * ports.c (scm_generic_fgets): Same as for scm_fgets.
778 * ioext.c (scm_read_line): Free string after Guilifying it.
779 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
781 1997-11-26 Anthony Green <green@hoser.cygnus.com>
783 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
785 * gh.h: Safely wrap prototypes for c++ usage.
787 1997-11-25 Mark Galassi <rosalia@cygnus.com>
789 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
790 gh_repl (argc, argv).
792 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
794 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
795 and to invoke scm_shell().
796 (gh_launch_pad): took out the loading of boot-9.scm from here,
797 since it is probably best to let the user control that. In fact,
798 gh_repl() now invokes scm_shell() which does that.
800 1997-11-23 Mark Galassi <rosalia@cygnus.com>
802 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
805 1997-11-22 Tim Pierce <twp@twp.tezcat.com>

808 yesterday's underscore patch. (Thanks to Marius Vollmer for
811 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
813 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
814 DLSYM_ADDS_USCORE is not defined.
816 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
818 * gh_data.c (gh_uniform_vector_length):
819 (gh_uniform_vector_ref): started implementing the uniform types in
822 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
824 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
825 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
827 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
829 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
830 configure.in was changed).
832 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
834 * Makefile.am (modinclude_HEADERS): Include readline.h here.

837 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
839 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
840 OPORT is an `open' port, not an output port.

843 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
844 SCM_COERCE_OUTPORT to cope with the printstate/port magic.

846 scm_close_port, scm_port_line, scm_set_port_line_x,
847 scm_port_column, scm_set_port_column_x, scm_port_filename,
848 scm_set_port_filename_x, scm_port_mode,
849 scm_close_all_ports_except, scm_set_current_output_port,
850 scm_set_current_error_port): Likewise
851 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
852 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
854 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
855 * backtrace.c (display_backtrace_body): Likewise
856 * fports (scm_setvbuf): Likewise
857 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
858 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
859 scm_getpeername, scm_send, scm_sendto): Likewise
860 * unif.c (scm_uniform_array_write): Likewise
862 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
864 Minor problems with substring-related tag changes.
865 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
866 exactly what we want to leave in to detect substrings.
867 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
868 * tags.h: Fix diagrams and comments describing the S tag bit;
869 remove vestigial remarks about the D tag bit.
870 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
871 * strings.c: Formatting tweaks.
873 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
874 variable first; then SCHEME_LOAD_PATH, with a warning message.
875 (scm_parse_path): New function.
876 * script.c: Doc fixes.
878 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
880 Readline support, from Daniel Risacher.

890 * gh.h: gh_vector_set -> gh_vector_set_x
892 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
894 * gh_data.c (gh_vector_set_x): changed name to make it consistent
895 with the ! -> _x mapping when going from Scheme to C.
897 1997-10-19 Mark Galassi <rosalia@cygnus.com>
907 (gh_assoc): added these gh_ functions implemented as macros.
909 * gh_predicates.c (gh_null_p):
910 (gh_string_equal_p): added these two missing predicates.
912 * gh_list.c (gh_append):
917 (gh_set_cdr_x): added these routines as I go through and try to
918 complete the picture R4RS functions that should be mirrored in the
921 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
923 * tags.h (scm_tc7_substring): Changed the comment and code to
924 conform with the changes below. Folks! We have suddenly two new
925 free tc7 codes!!! Jummy, jummy!
927 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>

950 (scm_tc7_mb_string): Removed.
951 (scm_tc7_mb_substring): Removed.
952 * print.c (scm_iprin1): Handle char printing directly. Don't
954 Don't include "mbstrings.h".
955 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
956 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
958 Don't include "mbstrings.h".
959 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
960 (SCM_SYMBOL_SLOTS): Define as 4.
961 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.

966 ("gen"-less) I/O function names.
967 * ports.c (scm_add_to_port_table): Don't set port's
969 * ports.h (scm_port_representation_type): Removed.
970 (scm_string_representation_type): Removed.
971 (struct scm_port_table ): Removed representation field.
972 (SCM_PORT_REPRESENTATION): Removed.
973 (SCM_SET_PORT_REPRESENTATION): Removed.

985 1997-10-12 Mark Galassi <rosalia@cygnus.com>
987 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
989 * gh_test_c.c (c_vector_test): some improvements on the vector
992 * gh.h (gh_vector): this used to exist but do the wrong thing.
993 Now it (almost) does the right thing, though it takes a list
994 instead of the individual arguments. I need to see how it could
996 (gh_list_to_vector): added this function as a macro. Corresponds
997 to Scheme's (list->vector ...).
998 (gh_vector_to_list): added this function as a macro. Corresponds
999 to Scheme's (vector->list ...).
1001 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1002 gh_vector_ref, so that it resembles the Scheme routines more.
1003 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1004 resembles the Scheme routines more.
1005 (gh_make_vector): this used to be (stupidly) called gh_vector().
1006 This is the right name, since it does the same thing as the Scheme
1007 (make-vector ...) procedure.
1009 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1011 * ports.h: #include "libguile/print.h"

1024 gh_int2scmb(), which is now tagged as obsolete.
1026 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1028 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1029 macros should by convention not test for NIMPness.)
1030 (SCM_COERCE_OPORT): Adjust indentation.
1032 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1033 SCM_NIMP test before SCM_PRINT_STATE_P.
1035 * struct.c, struct.h, gc.c: Renamed:
1036 scm_struct_i_layout --> scm_vtable_index_layout

1043 printing: Also output hex code of vtable so that type identity
1044 will be indicated as well.
1045 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1046 Removed struct_printer_var; Removed struct-vtable-offset;
1047 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1048 vtable-offset-user): New constants.
1050 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1051 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1052 If this slot contains a procedure, use that to print structures of
1053 the type represented by this vtable.
1055 * print.c (scm_iprin1): Don't print arguments of macro
1056 transformers. (They are always: exp env.); Bugfix: Unmemoize
1057 transformer source with correct environment.
1059 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1061 Streamlining of call-with-dynamic-root:
1063 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1064 there is now only one catch.
1065 (cwdr_outer_body): Removed.
1066 (cwdr_handler): New function.
1067 (scm_internal_cwdr): New function to perform the function of cwdr
1068 but take args that are more useful to C code. Also, the handler
1069 is now invoked *outside* of the new dynamic root, like the docs
1070 say. We no longer have to catch absolutely all errors, the caller
1071 is responsible for using a handler that does not throw, if he
1073 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1074 * root.h (scm_internal_cwdr): New prototype.
1076 Even more but risky streamlining:
1078 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1079 allocation of the jumpbuf of a root continuation. The changes
1080 below are controlled by it. They are now deactivated.
1081 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1082 the JMPBUF of the scm_rootcont to NULL before returning.
1084 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1085 when they are non-NULL.
1086 (scm_gc_mark): Likewise, mark only when non-NULL.
1088 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1089 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1091 * gc.c (scm_done_malloc): New function.
1092 gc.h (scm_done_malloc): New prototype.
1094 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
1095 (struct scm_print_state) [revealed]: New field.
1096 (scm_print_state_vtable): Make visible to the outside world for
1097 type checking purposes.
1098 (scm_valid_oport_value_p): New prototype.
1100 * print.c (scm_valid_oport_value_p): New function to check whether
1101 a certain value is acceptable as a port argument.
1102 (scm_print_state_vtable): New variable.
1103 (scm_free_print_state): Set `revealed' field to false.
1104 (scm_iprin1): Call user supplied closure printer with
1105 scm_printer_apply. Print in the traditional way when there isn't
1106 one or when it returns #f.
1107 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1108 Accept a port/print-state pair in addition to just a port.
1109 (scm_prin1): Don't return the print_state to the pool when it has
1111 (scm_printer_apply): Set `revealed' field of print_state to true.
1112 (scm_init_print): Set scm_print_state_vtable.
1113 (print_state_fluid, print_state_fluid_num): Removed.
1115 * throw.h (scm_handle_by_proc_catching_all): New prototype
1116 throw.c (scm_handle_by_proc_catching_all): New function
1118 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1120 * Makefile.in: Regenerated with automake 1.2c.
1122 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1124 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1125 was looping endlessly.
1127 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1129 * strports.c (scm_eval_string): Don't close the port.
1131 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1132 former returns a nice normal integer. (Thanks to Daniel
1135 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1137 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1138 makefile variable as a build parameter called LIBS. The
1139 build-guile program will use this, for the time being.
1140 * Makefile.in: Regenerated.
1142 Thanks to Shiro Kawai:
1143 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1144 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1147 * Makefile.in: Regenerated with automake 1.2a.
1149 * script.c (scm_compile_shell_switches): If we hit the -c or --
1150 arguments, don't set the car of (command-line) to scm_usage_name,
1151 the prettified name of the guile executable; give it the full
1152 path, the way shells usually handle $0.
1154 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1156 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1157 Scheme-level name `array-map' and renamed `serial-array-map' to
1158 `serial-array-map!'.
1160 * backtrace.c: Introduced exception handlers which now enclose
1161 `display-error' and `display-backtrace' so that error reporting
1162 won't get into infinite loops if an error occurs during displaying
1163 of the error. This can very easily happen with user supplied
1164 print call-back routines.
1166 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1168 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1169 the names `serial-array-map' and `array-map' should be removed.)
1171 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1173 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1174 Added #include "objects.h"
1176 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1177 Add #include "feature.h".
1179 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1180 (modinclude_HEADERS): Added objects.h.
1182 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1183 This test is needed at many places in the code and should be
1184 abstracted. (Motivated by the need of this test in libguiletk.)
1186 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1187 (scm_eval_string), load.c (scm_primitive_load,
1188 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1189 Use SCM_EOF_OBJECT_P.
1191 * eval.c (scm_init_eval): Add feature `delay'.
1193 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1195 * scmhob.h: Removed.
1197 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1199 * list.h (SCM_LISTn): New macros. Make list creation in C code
1200 prettier. The idea comes from STk.
1202 * sequences.h, sequences.c, append.h, append.c: Removed. These
1203 files implemented non-R4RS operations which would encourage
1204 non-portable programming style and less easy-to-read code.
1206 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1209 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1210 sequences.h, #include append.h.
1212 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1215 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1217 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1219 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1221 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1223 * eval.c: Added #include "objects.h"
1225 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1228 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1229 adjacent smob numbers.
1231 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1233 * procprop.h: Added declaration of scm_i_inner_name.
1235 * gsubr.c: New global symbol scm_i_inner_name.
1237 * debug.c (scm_procedure_name): Try procedure property
1238 `inner-name' if `name' fails.
1240 * print.c (scm_iprin1): Use scm_macro_name.
1242 * eval.c (scm_m_define): Give names to macros as well; Only the
1243 first top-level definition gives a procedure/macro a name.
1244 Otherwise confusing names can turn up in backtraces.
1245 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1246 `name'; Give names to macros as well.
1248 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1249 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1252 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1254 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1256 (prinmacro): Removed. The code has been moved/merged into print.c
1257 in order to decrease code redundancy. We want macros to print in
1258 a way equivalent to procedures, and it would be silly to duplicate
1259 the required code. (We don't want to maintain two places.)
1260 (macrosmob): Print field is now a NULL pointer.
1262 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1263 scm_macro_transformer): New prototypes.
1264 (scm_tc16_macro): Declared.
1266 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1267 are now printed in a way equivalent to procedures.
1269 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1271 * procs.h (scm_closure_p): Added declaration.
1273 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1275 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1276 Shouldn't pass "heap" as the subr name.
1278 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1280 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1281 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1282 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1283 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1284 SCM_BOOL_T. Any non-false value is true.
1286 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1288 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1289 scm_gensym): Added prototypes.
1291 * symbols.c (scm_gensym): New function. This will speed up
1292 certain types of applications (such as macro systems) which
1293 generate lots of symbols.
1295 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1297 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1299 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1301 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1302 specifier, since (2) or (2 . 3) would cause SEGV.
1303 (scm_transpose_array): more argument checking fixes.
1305 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1307 * Makefile.in: Regenerated.
1309 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1311 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1313 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1315 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1317 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1319 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1320 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1323 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1324 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1325 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1326 scm_array_p, scm_array_rank, scm_array_dimensions,
1327 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1328 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1329 scm_array_prototype): Added case scm_tc7_wvect.
1331 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1333 * errno.h: prototype for scm_strerror.
1334 * error.c (scm_strerror): new procedure.
1336 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1338 * list.c (scm_list_append_x): Allow non-pair as last argument.
1339 This is consistent with the R4RS append and is probably the
1340 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1342 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1344 * stime.h: prototype for scm_times.
1345 * stime.c (scm_times): new procedure.
1346 * ioext.c (scm_fseek): if the first argument is a file descriptor
1348 (scm_ftell): if the first argument is a file descriptor call lseek
1350 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1351 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1353 (scm_chown): if the first argument is a port or file descriptor,
1355 (scm_truncate_file): new procedure.
1356 Add DEFER/ALLOW INTS to a few other procedures.
1357 (scm_fsync): new procedure.
1358 (scm_open_fdes): new procedure.
1359 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1361 (scm_fcntl): the first argument can now be a file descriptor. The
1362 third argument is now optional.
1364 * posix.c (scm_execl, scm_execlp): make the filename argument
1365 compulsory, since omitting it causes SEGV.
1366 (scm_sync): return unspecified instead of #f.
1367 (scm_execle): new procedure.
1368 (environ_list_to_c): new procedure.
1369 (scm_environ): use environ_list_to_c. disable interrupts.
1370 (scm_convert_exec_args): take pos and subr arguments and
1371 improve error checking.
1373 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1375 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1376 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1377 argument to SCM_ASSERT. Furthermore, the name of the function
1378 should be passed as first argument when signalling
1379 SCM_WNA. (Thanks to Thomas Morgan)
1381 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1382 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1383 dispatches on the number of actual args has a default case
1384 reporting an internal error. This is a vestige from a version
1385 that mallocated a SCM vector to hold the arguments. In the
1386 current version this check is too late: if it ever happens we will
1387 have already overstepped the bounds of the array.
1389 Also, the patch [...] adds a check for too many actual arguments."
1391 mdj: Removed check for "internal programming error".
1393 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1395 * gh_io.c (gh_write): New function.
1397 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1398 throw.c (scm_internal_stack_catch): New sibling to the other catch
1399 functions. Code moved from gh_eval.c.
1400 throw.h: Added header.
1401 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1402 scm_internal_stack_catch.
1404 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1406 * ioext.h: fix up prototypes.
1407 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
1408 Scheme name is now dup->fdes.
1409 (scm_dup_to_fdes): make the second argument optional and
1410 fold in the functionality of scm_primitive_dup.
1411 (scm_primitive_dup): deleted.
1413 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1415 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1416 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1417 ultrix are defined. Use setvbuf instead of setbuf.
1418 (scm_setvbuf): new procedure.
1419 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1420 (scm_setfileno): moved from ioext.c.
1421 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
1422 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.

1431 * print.c (scm_iprin1): Enter printed structures into the print
1432 state as nested data while they are printed.
1433 (print_state_fluid, print_state_fluid_num): New variables.
1434 (scm_init_print): Initialize them.
1435 (scm_iprin): If print_state_fluid carries a print_state, use that
1436 instead of creating a new one.
1437 (scm_printer_apply, apply_stub, struct apply_data): New
1438 definitions to help with calling printer functions written in
1440 * print.h (scm_printer_apply): New prototype.
1442 * struct.c (scm_print_struct): Use scm_printer_apply to call the
1443 user defined struct printer.
1445 * dynwind.c (scm_dowinds): Handle fluids on the wind list.

1451 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
1453 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1454 SCM_ASSERT: arg comes before pos.
1456 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1458 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1459 to a list of length zero correctly.
1461 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1463 Supply an `fgets' method for port objects to do fast line i/o.

1477 * ioext.h: removed scm_duplicate_port prototype.
1479 * ioext.c (scm_primitive_dup2): return the new file descriptor
1480 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
1482 (scm_fdopen): bug fix: don't try to make port unbuffered until its
1483 stream has been set.
1484 (scm_duplicate_port): deleted, there's now an implementation in
1486 (scm_primitive_dup2): do nothing if newfd == oldfd.
1488 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
1490 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
1493 * ioext.h: new prototypes.
1494 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
1496 * fluids.c (next_fluid_num): don't do
1497 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
1499 * ports.h: prototypes too.
1500 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
1502 * fports.h: prototype too.
1503 * fports.c (scm_evict_ports): moved from ioext.c.
1505 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>

1510 * filesys.h: scm_close prototype.
1511 * filesys.c (scm_close): new procedure, can close file descriptors
1512 and ports (scsh compatible).
1514 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
1517 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
1519 * fluids.c, fluid.h: New files.
1520 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
1521 (modinclude_HEADERS): Added "fluids.h"
1523 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to
1524 scm_init_fluids to initialize the fluid machine.
1525 (scm_start_stack): Initialize the fluids of the first root with
1526 scm_make_initial_fluids.
1528 * root.h: Added "fluids" member to scm_root_state.
1529 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
1530 (scm_make_root): Call scm_copy_fluids to make fluid bindings
1531 unique for the new root when it has a parent.
1533 * smob.h: Include "libguile/print.h" to make scm_print_state
1536 * dynl.c (free_dynl_obj): New function to free the dynamic object
1537 data. (dynl_smob): Use it.
1538 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
1539 the dynamic object data below the linking of the object to avoid
1540 memory leak when the linking code throws an error. Now the code
1541 leaks a whole dynamically linked library when must_malloc throws,
1542 but that should be much less likely.
1544 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
1546 Changes to compile under gnu-win32, from Marcus Daniels:
1547 * stime.c (tzset): If tzset isn't provided, make it a NOP.
1548 (scm_localtime): Change SCM_EOF to SCM_EOL.
1549 (scm_mktime): Likewise.
1550 * socket.c: Don't include sys/un.h unless autoconf tells
1551 us Unix domain sockets are available.
1552 (scm_fill_sockaddr): Ignore Unix domain code.
1553 (scm_addr_vector): Likewise.
1554 (scm_init_addr_buffer): Likewise.
1555 (scm_socketpair): Don't include unless socketpair was
1556 found during autoconf.
1557 * simpos.c (SYSTNAME): Treat cygwin like Unix.
1558 * scmsigs.c (scm_pause): Don't include unless pause was found
1560 * posix.c (scm_getgroups): Don't include unless support function
1561 was found during autoconf (in this case, getgroups).
1562 (scm_setpwent): For setpwent.
1563 (scm_setegid): For setegid.
1564 * net_db.c (scm_inet_netof): Don't include unless support
1565 function was found during autoconf (in this case, inet_netof).
1566 (scm_lnaof): For inet_lnaof.
1567 (scm_inet_makeaddr): For inet_makeaddr.
1568 (scm_getnet): For getnetent, getnetbyname, getnetbyaddr.

1572 (scm_setnet): For setnetent, endnetent.
1573 (scm_setproto): For setprotoent, endprotoent.
1574 (scm_setserv): For setservent, endservent.
1575 * scmconfig.h.in: Regenerated.
1577 Thu Jul 10 00:22:24 1997 Jim Blandy <jimb@floss.red-bean.com>
1579 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
1580 scm_misc_error, not SCM_EOF.
1582 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
1583 arguments for formatting the error message, not SCM_BOOL_F. I
1584 think this is left over from the (eq? '() #f) days.
1586 * read.c (recsexpr): Give this a dummy definition if
1587 DEBUG_EXTENSIONS isn't #defined.
1589 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
1591 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
1594 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>
1596 * root.c (cwdr_outer_body): Bugfix: Pass `c' instead of `&c' to
1599 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
1601 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
1602 alloca.lo will be included in @LIBLOBJS@. Something better than
1603 this should be possible.
1604 * Makefile.in: Regenerated.
1606 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1608 * simpos.h: prototype for scm_primitive_exit.
1609 * simpos.c (scm_primitive_exit): new procedure, terminates the
1610 process without unwinding the stack.
1612 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
1614 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
1615 argument and logior its components together, so the user doesn't
1616 have to do this explicitly. Also, if regexp/basic is supplied, then
1617 turn off REG_EXTENDED.
1618 (scm_init_regex_posix): New regexp/basic symbol.
1619 (REG_BASIC): #define this if it is not already present.
1621 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1623 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
1624 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
1625 (CLEANFILES): New target, clean versiondat.h, libpath.h.
1626 (DISTCLEANFILES): New target, clean *.x.
1627 * Makefile.in: Regenerated.
1629 Tue Jun 24 00:29:07 1997 Jim Blandy <jimb@floss.red-bean.com>
1631 * script.c (scm_compile_shell_switches): Add 1997 to copyright
1632 years in usage message.
1634 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
1635 * Makefile.in: Regenerated.
1637 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
1638 flag; I don't think we support it.
1639 (scm_make_regexp): Make sure the user doesn't pass the
1642 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
1644 (scm_init_regex_posix): Define constants for the REG_mumble flags;
1645 name them according to the SCSH convention: regexp/mumble.
1647 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
1649 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
1651 * Makefile.am (libpath.h): Include the values of all the standard
1652 Makefile directory variables. Print a message, but don't print
1654 (versiondat.h): Print a message, but don't print all the commands.
1655 * load.c: #include "alist.h".
1656 (init_build_info): New function.
1657 (scm_init_load): Call it.
1658 * Makefile.in: Regenerated.
1660 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
1662 * root.c: Establish a reliable catch-all handler for the new root.
1663 After all the Scheme handler function might signal an error too,
1664 and we don't want to lose that.
1665 (cwdr_inner_body): Renamed from cwdr_body.
1666 (cwdr_outer_body): New function, to establish the user's handler,
1667 and pass control to cwdr_inner_body.
1668 (cwdr): Establish the reliable catch-all handler here, and pass
1669 control to cwdr_outer_body.
1670 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
1671 the user's handler through to cwdr_outer_body.
1672 * throw.c (scm_handle_by_message): Move guts into....
1673 (handler_message): New static function.
1674 (scm_handle_by_message_noexit): New function.
1675 * throw.h (scm_handle_by_message_noexit): New prototype.
1677 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
1678 across this. Only works on GCC. Otherwise, we hope for the best.
1679 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
1680 the feeling that real thread systems will not need this...
1682 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
1684 Try to detect when people are using one version of libguile and a
1685 different version of ice-9. People have been skewing things and
1686 sending in bug reports.
1687 * Makefile.am (versiondat.h): New file to generate.
1688 * version.c: #include "versiondat.h", to get version info.
1689 (scm_libguile_config_stamp): New function.
1690 * script.c: #include "version.h".
1691 (scm_compile_switches): Call scm_version to get version number.
1692 * scmconfig.h.in, Makefile.in: Regenerated.
1693 * Makefile.in: Regenerated.
1695 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
1696 primitive definitions under their Scheme names.
1698 * Makefile.am (libguile_la_LDFLAGS): Update library version to
1699 1:2. Helps avoid confusion between installed and uninstalled libs.
1701 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
1704 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
1705 backslash from definition; this should be used like: GDB_INTERFACE;
1707 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1709 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
1710 new port unbuffered until its stream has been set.
1712 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
1714 * ports.h: new prototype.
1715 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
1717 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
1719 Make things compile neatly under Sun's C compiler.
1720 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
1721 * extchrs.c (xmbtowc): Make the second arg a normal char, not
1722 unsigned, because that's what the ANSI function takes.
1723 * extchrs.h (xmbtowc): Corresponding change to prototype.
1724 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
1726 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
1727 argument plain char *.
1728 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
1730 * tag.c (scm_tag): Remove unreachable statement.
1731 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
1732 top of the word, it should be unsigned.
1734 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
1735 is defined, to avoid warnings; it's only used in the
1736 conflict-checking code. Which might go away anyway.
1737 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
1738 conditionals; put the label definition in an #if too, to stifle
1741 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
1742 ChangeLog-threads in the distribution.
1743 * Makefile.in: Regenerated.
1745 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1747 * guile-snarf.in: Changed regexp to support CPPs that insert
1748 whitespace between lexical tokens (which munges the `%%%' snarf
1751 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1753 * load.c (scm_init_load_path): Append $(datadir)/guile to
1754 %load-path, so modules do not have to be installed in Guile's
1755 current version directory.
1757 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
1759 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
1760 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
1761 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
1762 call the sysdep functions with deferred ints.
1763 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
1764 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
1765 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
1768 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
1771 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
1773 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
1775 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
1777 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
1780 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
1782 * eval.c (scm_lookupcar1): New procedure to cope with a race
1783 condition during lookup (when using threads).
1784 (scm_lookupcar): Implement in terms of scm_lookupcar1.
1785 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
1788 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
1790 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
1791 supplied. (Change from Tim Pierce.)
1793 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
1795 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
1796 23:47:01 1997" changelog: Slots are now initialized with `#f' by
1797 default and not `()'. `#f' is the canonical non-value in Scheme,
1800 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1802 * struct.c (struct_printer): New variable that holds a handle on
1803 the Scheme variable *struct-printer*. This variable can be set by
1804 Scheme code to override the printing of structures.
1805 (scm_print_struct): If struct_printer is set, call it. If it is
1806 not set, or returns #f, print the structure in the old fashion.
1807 Include "eval.h" for scm_apply.
1809 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
1811 * struct.c (scm_struct_ref, scm_struct_set_x): Use
1812 scm_struct_i_n_words to get the number of fields, not
1813 -scm_struct_n_extra_words.
1815 On the route to fancier struct printing:
1816 * struct.c (scm_print_struct): New function to print a structure.
1817 Include "genio.h" to support it. This function doesn't do
1818 anything interesting right now, but I think it should be here
1820 * struct.h: Include "print.h" and add prototype for
1822 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
1823 print structures ourself.
1825 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
1827 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
1828 before applying the handler in case it doesn't return.
1830 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
1832 * scmsigs.h, async.h: updated.
1834 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
1837 * posix.c (scm_uname): interpret only negative values as an error.
1838 Solaris normally returns a positive value.
1840 * script.c (scm_compile_shell_switches): if we are not going into
1841 an interactive repl, set scm_mask_ints to zero so that asyncs can
1844 * simpos.c (scm_system): don't ignore/unignore signals around
1847 * posix.c (scm_open_pipe): don't ignore/unignore signals around
1850 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
1851 done in boot-9.scm instead.
1853 * scmsigs.c, async.c: Major rewriting of signal handling code.
1854 (scm_sigaction): new procedure.
1855 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
1857 (scm_raise): return unspecified, throw error on failure.
1859 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1861 * regex-posix.c (scm_init_regex_posix): Register the "regex"
1862 feature, to help boot-9.scm decide whether to import the regex
1865 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1867 * eval.c: Include scmconfig.h at the beginning of the file so that
1868 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
1871 * regex-posix.c: #include "_scm.h" before conditionally #including
1872 <regex.h>; the former defines HAVE_REGCOMP.
1874 * regex-posix.c: #include <regex.h> conditionally, so the file is
1875 CPP'able (for dependency scanning) even on systems that don't have
1878 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
1880 Add new R4RS-compliant syntax for keywords.
1881 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
1882 regardless of the setting of the `keywords' read option.
1883 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
1884 can be re-read no matter what the setting of the `keywords' read
1887 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
1889 Add support for POSIX regular expressions.
1891 * regex-posix.c, regex-posix.h: New files. (Some code
1892 is taken liberally from rx/rgx.c in the old Guile dist.)
1894 * init.c: Include regex-posix.h.
1895 (scm_boot_guile_1): Call scm_init_regex_posix.
1897 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
1898 Add regex-posix.[ch] sources.
1899 * Makefile.in: Regenerated.
1901 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
1902 to do this automatically? It didn't for me, bleh.)
1904 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
1906 * fports.c (print_pipe_port): New function.
1907 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
1908 latter doesn't even take the right arguments.
1910 * Makefile.am: Increment shared lib revision number. I think
1911 sometimes the uninstalled Guile finds the installed shared lib;
1912 Gord says doing this might help. As things turned out, I can't
1913 say whether it does.
1914 * Makefile.in: Regenerated.
1916 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
1917 passing it as the closure argument to scm_boot_guile. (Bill
1920 * ports.c (print_void_port, putc_void_port, puts_void_port,
1921 write_void_port, flush_void_port, getc_void_port, close_void_port,
1922 noop0): Use ANSI prototypes instead of K&R declarations, so the
1923 initialization of void_port_ptob gets aggressively type-checked.
1924 Fix arguments of print_void_port and write_void_port. (Bill

1960 * script.c (scm_find_executable): Use prototype-style definition
1961 here; apparently it's not quite right to have const in a prototype
1962 and then use a K&R declaration. I wonder if stuff like this will
1963 go away if we compile with -Wrequire-prototypes, or whatever that
1964 is... (Bernard URBAN)
1966 * scmhob.h: New text from Bernard URBAN.
1968 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1970 * script.c: Don't #define const on hpux. Configure takes care of
1971 this. (Thanks to Larry Schwimmer.)
1973 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
1974 decide whether to #include <unistd.h>, instead of listing a bunch
1975 of systems. Don't #include stdio twice. Removed dyked-out
1976 definition of scm_find_impl_file.
1978 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
1980 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared

1987 init.c, net_db.c, options.c, options.h, ports.c, print.c, read.c,
1988 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
1989 throw.c: Update copyright years; these files have been worked on
1990 significantly in 1997, but only had copyright years for 1996.
1991 Also, change name of copyright holder on some from Mikael
1992 Djurfeldt to Free Software Foundation; he has signed papers
1993 assigning the changes to the FSF.
1995 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
1996 reason not to give the user the option.
1998 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
1999 Return #f on end-of-file when scanning table (i.e. when called
2000 with no arguments). Try to catch errors, when we can.
2001 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2003 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2004 external declarations. These are useful.
2006 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2008 * posix.c: don't include <sys/select.h> or define macros for
2009 select, since they were not used in this file.
2011 * filesys.c (scm_select): make the fifth parameter microseconds,
2012 not milliseconds. let the fourth parameter be either a real value
2013 or an integer or #f. The first, second and third arguments can
2014 now be vectors: the type of the corresponding return set will be
2016 (set_element, get_element): new static procedures.
2018 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2020 * strports.c (scm_eval_string): New function.

2027 * fports.c (local_pclose): New function.
2028 (scm_pipob): Use it in the initializer here.
2031 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2032 Use a meaningful error message when signalling an error. For
2033 this, scm_gethost must check h_errno rather than errno.
2035 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2037 * Makefile.in: Regenerated, using automake-1.1p.

2041 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2042 not SCM_UNSPECIFIED.
2044 * script.c (scm_compile_shell_switches): don't append (quit) if
2046 (scm_shell): call scm_exit_status and exit on the result of the
2049 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2051 Ensure that shared substrings are handled properly when passed to
2052 a system call or other foreign function. Many thanks to Tim
2054 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2055 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2056 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2057 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
2058 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
2059 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2060 (scm_display_error_message): use RO macros when strings may be RO.
2061 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2062 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2063 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
2064 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
2065 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
2066 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
2067 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
2068 scm_strftime), vports.c (scm_make_soft_port): use
2069 SCM_COERCE_SUBSTR to make sure shared substrings are

2074 * error.c (scm_error): Add newline to error message.
2076 * init.c (scm_init_standard_ports): Doc fix.
2078 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2080 * dynl-shl.c: Completely replaced with new code from Bernard
2083 * script.c (scm_ice_9_already_loaded): New variable.
2084 (scm_compile_shell_switches): Use it.
2086 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2088 * filesys.c (scm_input_waiting_p): add missing third argument to
2091 * stime.c (scm_localtime): copy the result of localtime before
2092 calling gmtime in case they share a buffer.
2093 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE

2098 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2100 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2102 * Makefile.am (check-local): New target, which causes 'make check'
2103 to run gh_test_c and gh_test_repl, with some trivial input.
2104 * Makefile.in: Rgnrtd.
2106 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2108 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2111 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2113 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2114 sure how this was supposed to work.
2115 (scm_async_click): don't send SCM_TICK_SIGNAL.
2116 (scm_init_async): don't initialize %tick-thunk.
2118 * the following change doesn't affect the Scheme interface:
2119 gc-thunk is called at the end of garbage collection. however it's
2120 no longer implemented by pretending it's a signal.
2122 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2123 system async corresponding to scm_gc_thunk.
2124 * async.h: declare scm_gc_async.
2125 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2126 gc-thunk directly, instead of going through a signal handler.
2127 (scm_gc_async): new variable, points to the GC system-async.
2128 (scm_init_async): save the GC async as scm_gc_async instead
2129 of using system_signal_asyncs.
2130 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2132 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2134 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2135 Don't screw up if we're interrupted.
2136 * Makefile.in: Regeneradet.
2138 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2140 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2142 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2143 we're not using AM_INIT_GUILE_MODULE any more.
2144 * Makefile.in: Reneregated.
2146 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2148 Functions for finding variable bindings, grace à Tim Pierce.
2149 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2150 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2152 Get 'make dist' to work again.
2153 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2154 * Makefile.in: Regenerated, like a surry without a fringe on top.
2156 Changes for reduced Guile distribution: one configure script,
2158 * configure.in, configure: Removed.
2159 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2160 real configure script lives.
2161 * Makefile.in, scmconfig.h.in: Regenerated.
2163 * init.c: #include "script.h", to get prototype for script.c's
2166 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2168 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2169 scm_must_malloc, not raw malloc.
2171 * script.c (scm_compile_shell_switches): Dyke out debugging output
2174 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2176 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2178 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2179 system has them. Hope this is safe. Previously
2180 sys/timeb.h was included if HAVE_FTIME was defined or if
2181 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2182 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2184 * ioext.c (scm_setfileno): add missing third argument to
2185 scm_misc_error call.
2187 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2189 * eq.c (scm_equal_p): Correctly compare strings of different
2190 varieties. (Thanks to Tim Pierce.)
2192 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2194 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2195 #! block comment must occur on a line all by itself.
2197 Move most of the guts of shell command processing into libguile,
2198 so guile.c can be very small (and eventuallly auto-generated. (I
2199 mean, generated mechanically, not self-generated. Hmm.))
2200 * guile.c, script.c, script.h: New source files.
2201 * init.c (scm_boot_guile_1): Call scm_init_script.
2202 * libguile.h: #include "script.h".
2203 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2204 targets, for new executable.
2205 (libguile_la_SOURCES): Mention script.c.
2206 (modinclude_HEADERS): Add script.h.
2207 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2208 not dynamic linking is enabled. This is because we're generating
2209 executables now. Move CY_AC_WITH_THREADS call after those, so the
2210 values of cy_cv_threads_libs captures the libs chosen above.
2211 * Makefile.in, configure, aclocal.m4: Regenerated.
2213 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2214 We don't maintain this interface any more, and it just confuses
2217 * alloca.c: #include <scmconfig.h>, not <config.h>.
2218 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2219 it'll get included in disties.
2221 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2223 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2224 be distributed, because they confuse people.
2225 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2227 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2229 * configure.in: check for presence of gethostent (not present on
2230 OpenBSD by default).
2231 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2232 * configure, scmconfig.h.in: Regenerated.
2234 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2236 * backtrace.c (scm_backtrace): Split message string across
2237 newlines properly. GCC is more tolerant of this than other
2240 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2242 Merge threads directory into libguile.
2243 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2244 threads.h: New source files.

2246 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2248 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2249 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2250 coop-threads.c.cygnus, coop-threads.h.cygnus.
2251 * configure.in: If we're using threads, include threads.o in
2253 * _scm.h, libguile.h: threads.h lives in this directory now.
2254 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2255 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2256 currently used, but brought along for information's sake.
2257 * ChangeLog-threads: log from old 'threads' directory.
2258 * Makefile.in, configure: Rebuilt.
2260 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2262 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2265 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2267 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2269 Merge GH interface library into libguile.
2270 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2271 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2272 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2273 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2275 (EXTRA_libguile_la_SOURCES): ... here.
2276 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2277 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2278 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2279 New variables, describing how to build the gh test programs.
2280 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2281 build the test programs, and we probably should have been linking
2282 libguile.la against them all along, to support AIX shared libs.
2283 Add cflags for threads to CFLAGS; add libs for threads to new
2284 variable THREAD_LIBS, used in Makefile.am.
2285 * ChangeLog-gh: log from old `gh' subdirectory.
2286 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2288 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2290 * acconfig.h: Undo change of Apr 9; including the definition of
2291 PACKAGE in the guile headers conflicts with applications' own
2293 * scmconfig.h.in: Regenerated.
2295 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

2302 when PROC is receiving no arguments.
2304 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2306 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2307 have S_IFSOCK. This is the case under Ultrix.
2309 * posix.c (scm_status_exit_val, scm_status_exit_val,
2310 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2311 Ultrix versions of WIFSTOPPED, etc., which assume that their
2312 arguments are lvalues (hmm).
2314 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2316 * eval.c: Doc fixes.
2318 * throw.c: Doc fixes; rearranged.
2320 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.

2324 * acconfig.h: Added entry for PACKAGE.
2325 * scmconfig.h.in: Regenerated.

2328 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2329 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the

2333 * Makefile.in: Rebuild.
2335 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2337 * stime.c (scm_mktime): take an optional zone argument.
2338 (scm_localtime): check putenv return value.
2339 (scm_strftime, scm_strptime): moved from posix.c. move #include
2341 stime.h, posix.h: update prototypes.
2342 (bdtime2c, setzone, restorezone): new static procedures.
2343 (scm_mktime, scm_strftime): use them.
2344 (scm_strftime): don't call mktime before strftime. Use
2345 filltime for return value.
2346 (filltime): convert NULL zname to #f.
2347 (scm_strptime): return a count of characters consumed, not
2348 the remaining string.
2350 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2352 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
2353 (scm_mktime): likewise.
2355 Uncomment localtime and mktime.

2359 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2361 * stime.c (scm_init_stime): don't define ticks/sec.
2362 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2363 return value problem and is still portable.)
2365 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2367 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2368 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2369 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2370 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2371 cpp_err_symbols.c): Corresponding changes.
2372 * Makefile.in: Regenerated.
2374 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
2376 * posix.c (scm_putenv): don't check HAVE_PUTENV.
2377 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.

2379 * putenv.c: new file, from sh-utils 1.12.
2381 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2382 since allocation isn't for Scheme objects.
2383 (scm_putenv): copy strings before placing in the environment.
2385 * stime.c (scm_current_time): throw an error if time returns -1,
2386 instead of returning #f.

2388 scm_long2num for return value instead of SCM_MAKINUM.
2390 * stime.h: prototypes updated.
2392 * stime.c (scm_time_in_msec): apparently unused, deleted.
2394 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2396 * configure.in: check for gettimeofday.
2398 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2399 which may be more usefully portable than a gettimeofday interface.
2401 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2403 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not

2409 * stime.c (filltime): recovered static procedure.
2410 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2413 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2414 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2416 * posix.c (scm_mknod): split the mode argument into type and perms
2417 arguments, like the extra fields returned by stat.
2419 * fports.c (scm_pipob): set the close, free and print procedures.
2420 (scm_close_pipe): new procedure.
2422 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2423 define them in boot-9.scm
2425 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2427 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2428 wan't defined. Don't include fd.h.
2430 * Previously fd.h was regenerated whenever configure was run,
2431 forcing a couple of files to be recompiled.
2433 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2434 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2435 Check for _fileno as well as _file.
2437 * ioext.c: don't fd.h.
2438 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2441 * Change the stratigy for getting information about errno
2442 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2443 generating lists of symbols during the build process, which will
2444 not always work, include comprehensive lists in the distribution.
2445 To help keep the lists up to date, the "check_signals" and
2446 "check_errnos" make targets can be used.
2448 * configure.in: don't check for a command to extract errno codes.
2449 * Makefile.am: update file lists, remove errnos.list and errnos.c
2450 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2451 check_errnos targets.
2452 (CLEANFILES): remove errnos.c and errnos.list, add
2453 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2454 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2455 * errnos.default: deleted.
2456 * cpp_signal.c: new file.
2457 * cpp_errno.c: renamed from errnos_get.c.
2458 * cpp_err_symbols, cpp_sig_symbols: new files.
2459 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2460 * error.c (scm_init_error): #include cpp_err_symbols instead of
2462 * posix.c (scm_init_posix): don't intern signal symbols. #include
2465 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2467 * strop.c (scm_i_index): allow the lower bound to be equal to the
2468 length of the string, so a null string doesn't always give an error.
2470 * posix.h: new prototypes.
2471 * posix.c (scm_status_exit_val, scm_status_term_sig,
2472 scm_status_stop_sig): new functions, as in scsh. They break down
2473 process status values as returned by waitpid.
2475 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2477 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2478 configure doesn't know about it.
2480 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2482 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2484 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2485 which defines C variables with global linkage.
2487 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2489 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2492 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2494 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2495 has time to check why this doesn't work well with continuations.
2497 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2499 * Fix shell syntax error; some shells won't tolerate
2500 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2502 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2504 * posix.c (scm_uname): throw an error if uname fails instead
2507 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
2509 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
2512 * async.c (scm_ints_disabled): definition moved from error.c.
2514 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2516 * acconfig.h: Removed PACKAGE.
2518 * scmconfig.h.in: Regenerated.
2520 * snarf.h: g++ says it's non-portable not to specify the first
2521 argument in a varargs declaration. I introduced the first
2522 argument by using preprocessor conditionals.
2524 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
2526 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
2527 (scm_freopen): use RO string macros for filename and modes.
2528 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
2530 * posix.c (scm_getgrgid): simplify conversion of name to C string.
2531 (scm_mknod): use RO string macros for path.
2533 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
2534 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
2536 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2537 use SCM_ROSTRINGP and SCM_ROCHARS.
2539 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2541 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
2544 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
2545 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
2546 support for byte vectors.
2548 * print.c (scm_iprin1): Limit number of vector elements printed
2549 according to pstate->length.
2551 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2553 * backtrace.c (scm_display_error_message): don't segv if message
2556 * error.h: prototype for scm_error_scm.
2558 * error.c (scm_error_scm): new procedure, reimplements scm-error
2559 in C and uses scm_error.
2561 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2563 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
2564 pointer to the Scheme variable read-hash-procedures and intern it
2565 in scm_init_read. Modify scm_read_hash_extend and
2566 scm_get_hash_procedure to use the pointer.
2568 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2570 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
2571 (SCM_KEYWORD_STYLE): defined.
2573 * read.c (scm_read_opts): add a keywords option. This isn't a
2574 boolean option, in case someone wants to add support for DSSSL
2576 Setup scm_keyword_prefix symbol.
2577 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
2579 I've left keyword support disabled by default, since it doesn't
2580 seem to break the module system and it gives R4RS standard behaviour.
2581 It can be reactivated with (read-set! keywords 'prefix).
2583 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2585 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
2586 before constructing arbiter.
2588 * eval.c (scm_m_define): Bugfix: Check that the object is a
2589 closure before setting the procedure property!
2591 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
2593 * ports.c: Removed `ungetc-char-ready?'.
2595 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
2597 * read.c (scm_init_read): intitialise scm_read_hash_procedures
2598 (idea from Mikael: make it a pair so scm_permanent object only
2600 (scm_read_hash_extend): don't call scm_permanent_object.
2601 (ideas from Mikael): if chr is already in the list, replace its
2602 procedure instead of appending it again. If proc is #f, remove
2604 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
2606 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
2608 * gdbint.c (gdb_read): update scm_lreadr usage.
2610 * load.h: update prototypes.
2612 * load.c (scm_primitive_load, scm_read_and_eval_x,
2613 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
2615 * read.h: add prototype for scm_read_hash_extend. Change args for
2618 * read.c (scm_read_hash_procedures): new variable.
2619 (scm_read_hash_extend): new procedure.
2620 (scm_get_hash_procedure): new procedure.
2621 (scm_lreadr): use scm_get_hash_procedure instead of an argument
2622 for extended # processing.
2623 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
2624 scm_read_token): remove case_i, sharp arguments. Change callers.
2626 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
2628 * read.h (SCM_N_READ_OPTIONS): increase to 3.
2629 (SCM_CASE_INSENSITIVE_P): define.
2631 * read.c: add case-insensitive option to scm_read_opts.
2632 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
2633 to determine whether to convert symbol case.
2634 (default_case_i): definition removed.
2635 * read.c (scm_read_token): if case_i, downcase ic before doing
2638 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2640 * configure.in: Added configuration option `guile-debug'.
2641 Configure with --enable-guile-debug if you want a bunch of extra
2642 functions used for debugging when developing Guile.
2644 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
2646 * procs.c (make-cclo): New undocumented debugging procedure: Make
2647 compiled closure with internal procedure PROC and length LENGTH.
2648 Only compiled if GUILE_DEBUG is defined.
2650 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
2652 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
2654 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
2656 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
2657 with 3 or more args internally to the evaluator.
2659 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2661 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
2662 with 3 or more args internally to the evaluator. This is mainly
2663 because we don't want to pass entry and exit points of the
2664 debug support twice, but it also seems to increase the speed of
2665 the evaluator for such calls (e. g. (+ 1 2 3)).
2667 * backtrace.c (scm_display_application): New procedure:
2668 display-application; Set fancy printing parameters individually
2669 for different types of display (backtrace, error, application).
2670 (These should of course be customizable!)
2672 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
2673 clear the CHECK-flags.
2675 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2677 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
2679 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2681 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
2682 from pairs with a GLOC in the car.
2684 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
2685 otherwise `symbol-hash' will behave badly.
2686 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
2687 we get segmentation fault!
2689 * symbols.c: Added #include "weaks.h". New functions:
2690 `builtin-bindings' and `builtin-weak-bindings'. (These will be
2691 moved to an extraneous library when we split libguile.)
2693 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2695 * filesys.c (scm_stat): stat now takes fport arguments too as
2696 documented in the manual.
2698 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2700 * debug.c (scm_single_step): Bugfix: Call continuation with
2701 scm_call_continuation instead of throwing to it.
2703 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
2705 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
2706 argument wasn't declared to be optional.
2708 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2710 * stime.c (scm_init_stime): Add feature "current-time".
2712 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2714 * throw.h: prototype for scm_exit_status.
2715 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
2716 args to derive an exit status. Allows (quit) to work from a
2718 (scm_exit_status): new function.
2721 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2723 * eval.c (scm_deval): Removed some old code.
2724 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
2726 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
2729 * symbols.c (msymbolize): Bugfix: Must initialize property list to
2732 * procs.c: Introduce the existent C function scm_thunk_p at the
2733 Scheme level as well.
2735 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2737 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
2738 used from C to easily lookup the value of a symbol in the current
2741 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2743 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
2744 scm_init_unif in this file. This will also fix a previous problem
2747 * configure.in: Added AM_MAINTAINER_MODE
2749 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2751 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
2754 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
2756 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
2757 source files that are not always included in libguile but should
2758 have their dependencies calculated by automake. This variable is
2759 recognized by automake, no further magic is needed.
2760 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
2761 to deal exclusively with *.lo files, as it seems. The *.o files
2762 are built automatically when the corresponding *.lo file gets
2765 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
2767 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
2770 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
2772 * unif.c (scm_array_set_x): minor change to argument error checking.
2774 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
2776 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
2777 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
2778 They should only be included in the library at configure.in's
2780 (libguile_la_LDADD): Include the appropriate .lo files here.
2781 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
2782 so we know when to build them (and their .lo bretheren).
2783 * configure.in (LIBLOBJS): New substituted variable. We let
2784 configure decide which .o files to include in LIBOBJS, and then
2785 put the corresponding list of .lo files in LIBLOBJS. The latter
2786 is what we pass to libtool.
2787 * Makefile.in, configure: regenerated.
2789 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
2791 * symbols.c (scm_sysintern0): New function. Contains the core of
2792 old scm_sysintern but doesn't take a second value argument.
2793 (scm_sysintern): Now uses scm_sysintern0.
2794 (scm_sysintern_no_module_lookup): Renamed to
2795 scm_sysintern0_no_module_lookup and doesn't take a second value
2796 argument any longer.
2798 * symbols.h (scm_sysintern0: Added declaration.
2800 * options.c (scm_init_opts): Use scm_sysintern0 instead of
2801 scm_sysintern when interning option keys. Otherwise we risk
2802 destroying the values of already interned variables.
2804 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
2805 scheme-level boolean (use SCM_NFALSEP).
2807 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
2809 (scm_backtrace): New function. (C version of old function from
2810 boot-9.scm) Motivation: Make it possible to display backtraces
2811 without depending on boot-9.scm. (I'm uncertain if this
2812 motivation is good enough...)
2814 * root.h (scm_root_state): Add member the_last_stack_var.
2815 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
2817 * root.c (mark_root): Mark scm_the_last_stack_var.
2819 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
2822 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
2824 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
2825 1. mark_lazy_catch didn't mark the smob.
2826 2. Both functions above have standard variants:
2827 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
2828 free_lazy_catch --> scm_free0.
2830 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
2832 * throw.c (scm_internal_lazy_catch): New function.
2833 (scm_lazy_catch): Rewritten to use it.
2834 (scm_ithrow): Handle the new lazy catch representation.
2835 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
2836 that doesn't have a jmpbuf is a lazy catch clause.
2837 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
2838 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
2839 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
2841 (scm_init_throw): Register the new lazy-catch smob type.
2842 * throw.h (scm_internal_lazy_catch): decl for new function.
2844 * throw.c (scm_internal_catch): Doc fixes.
2846 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
2847 configure.in. Including this might cause problems if applications
2848 that link against libguile include their own copies of alloca, but
2849 if they're using autoconf, they should be adding libguile to LIBS
2850 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
2851 the copy in libguile, and things will be okay. (I think.)
2853 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2855 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
2857 strop.h: move prototypes too.
2859 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2861 * posix.c (scm_init_posix): don't intern EINTR since it's now done
2864 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
2865 etc. I deleted them from filesys.c long ago, but didn't
2866 notice they were here too (although ineffective since
2867 sys/stat.h wasn't included).
2869 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
2871 * eval.c: Don't define alloca in GCC case. gcc will automatically
2872 use __builtin_alloca if appropriate.
2874 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2876 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
2877 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
2878 that values of automatic variables are preserved. See comments
2879 for safe_setjmp for details.
2881 Change from Thomas Morgan:
2882 * variable.c: Include eq.h.
2883 (var_equal): New function.
2884 (variable_smob): Use var_equal as the discriminator for variables.
2886 * throw.c (s_throw): Remove extraneous declaration.
2888 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
2889 * eval.c: Add necessary CPP cruft to support that.
2890 * configure, Makefile.in, scmconfig.h.in: regenerated.
2892 Change from Thomas Morgan:
2893 * procprop.c (scm_procedure_properties): Convert the Scheme
2894 boolean returned by scm_procedure_p into a C boolean before using
2895 it as a condition for SCM_ASSERT.
2896 (scm_procedure_property): Likewise.
2898 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
2899 indications of Unixness.
2902 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2904 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
2906 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2908 * read.c (scm_lreadr): use scm_misc_error to improve one of the
2909 "unknown # object" error messages.
2911 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
2912 (scm_i_index) and declare it static. Add a 'direction' argument
2913 to indicate what way the search should go.
2914 (scm_i_index): throw out-of-range error instead of wrong-type-arg
2916 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
2917 strop.h: remove scm_i_index, scm_i_rindex prototypes.
2919 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2921 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
2923 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
2924 to avoid clash with various scsh forks.
2926 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
2928 The following two changes (ramap.c, throw.c) are motivated by the
2929 apparent unportability of forward declarations of static arrays of
2930 the form `static foo bar[];'.
2932 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
2933 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
2935 * throw.c (scm_throw): Moved above scm_ithrow.
2937 * options.h: Removed the extern declarations of scm_yes_sym and
2938 scm_no_sym since these are static.
2940 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2942 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
2944 * Makefile.am: remove AWK=@AWK@.
2945 Add a rule for generating errnos.list.
2946 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
2948 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
2949 don't extract errnos, just set a variable (avoids the
2950 need to recompile error.c just because configure is run.)
2952 * unif.h: update prototypes.
2953 * unif.c (scm_uniform_array_read,write): change the offset and
2954 length arguments to start and end, for consistency.
2956 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
2958 * ioext.h: update prototypes.
2959 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
2960 scm_read_line_x, it's a more general procedure using an
2961 interface from scsh. read-line and read-line! are now defined
2963 Note that the new read-line trims the terminator
2964 by default, previously it was appended to the returned string. An
2965 optional argument specifies how to process the terminator (scsh
2966 compatible). For the old behaviour: (read-line port 'concat).
2967 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
2968 returns a pair, but is converted to multiple values if the scsh
2971 socket.h: update prototypes.
2972 * socket.c (scm_recvfrom): for consistency with other procedures,
2973 take start and end as separate optional arguments.
2974 (scm_recv, scm_recvfrom): don't allow the second argument
2975 to be a size, only a buffer. Change the scheme names to
2976 recv! and recvfrom!. Don't return the buffer.
2978 * ioext.h, posix.h: move prototypes too.
2979 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
2980 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
2981 "read.h" and "unif.h".
2982 * ioext.c: include "chars.h"
2984 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
2986 * dynl.c: The dynamic linking and module registration functions
2987 are now defined even when dynamic linking is not available for the
2988 host system. Some of their functionality can be done without
2989 dynamic linking; when it's really needed, they throw errors.
2991 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
2993 * configure.in: Only define DYNAMIC_LINKING when one of the system
2994 dependent functions is detected.
2995 * dynl.c (scm_dynamic_func): New function to get the address of a
2996 function in a dynamic object.
2997 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
2998 produced by scm_dynamic_func as the thing to call.
3000 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3002 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3003 (scm_register_module_xxx, scm_registered_modules,
3004 scm_clear_registered_modules): New functions.
3006 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3008 * symbols.c (scm_sysintern): Renamed to
3009 scm_sysintern_no_module_lookup.
3010 (scm_sysintern): New function to take the place of the old
3011 scm_sysintern. It uses the current toplevel lookup closure to give
3012 the symbol its value. This is a temporary hack to put packages
3013 like gtcltk into their own module.
3014 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3015 us whether `scm_top_level_lookup_closure_var' has been initialized
3017 * eval.c (scm_init_eval): Set it.
3019 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3021 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3022 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3024 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3026 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3027 scm_sys_dup): deleted: FD capability will be added to other
3029 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3030 scm_fd_free, fd_smob, scm_intern_fd.
3031 (scm_open): renamed from scm_sys_open. Return a port instead of
3032 an FD object. Make the mode argument optional.
3033 (scm_sys_create): deleted, it's just a special case of open.
3034 (scm_init_filesys): move interning of constants O_CREAT etc.,
3035 here (were previously using SCM_CONST_LONG macro).
3036 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3038 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3039 include "fports.h" and <stdio.h>
3040 (scm_stat, scm_select): don't support FD objects.
3042 * error.h: adjust scm_syserror_msg prototype.
3043 * error.c (scm_syserror_msg): take an extra argument for errno.
3044 Using the global value didn't always work, since it could be
3045 reset by procedure calls in the message or args arguments.
3047 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3048 I don't understand why the check was there (and what about the
3051 * strop.c (scm_string_copy): allow shared substrings to be copied.
3053 * unif.h: corresponding change to prototypes.
3054 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3055 recognize two new optional arguments: offset and length. Allow
3056 the port argument to be an integer (file descriptor, for scsh).
3057 Include <unistd.h> for "read" prototype.
3059 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3061 * socket.c: don't include filesys.h.
3063 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3065 * Makefile.am: add AWK=@AWK@ (?)
3067 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3069 Add a rule to generate errnos.c from errnos.
3070 * error.c (scm_init_error): include errnos.c.
3071 * errnos_cnvt.awk: new file, converts the list of errno codes to
3073 * errnos_get.c: new file.
3074 * errnos.default: new file, contains errnos to try if they can't
3075 be extracted from errno.h.
3076 * configure.in: if using GCC, try and extract errno codes from
3080 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3082 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3083 * Makefile.am: Made libguile into a libtool library.
3084 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3085 Set libtool_libs to indicate that libguile is a libtool library.
3086 See guile/ChangeLog for details.
3087 * .cvsignore: ignore "*.lo", the libtool library objects.
3089 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3091 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3092 use htons in getservbyport argument.
3094 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3096 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3097 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3100 * objprop.c (scm_object_property): No need to take the CDR of the
3101 value returned by scm_object_properties, since Aug 20 change.
3103 * configure.in: When checking for struct linger, #include
3104 <sys/types.h> as well as <sys/socket.h>. I've never known
3105 <sys/types.h> to cause any portability problems, and Solaris's
3106 <sys/socket.h> needs it.
3107 * configure: Rebuilt.
3109 I think the Sun compiler has chosen a perverse way to interpret
3110 ANSI declarations combined with K&R definitions. We'll
3111 appease it a little bit. But when it invades France, we fight.
3112 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3113 * print.h (scm_iprlist): Here too.
3114 * numbers.c (scm_divbigdig): Change definition to match
3115 declaration in numbers.h.
3116 * unif.c (scm_makflo): Change definition to match declaration in
3119 * init.c (scm_boot_guile): Don't return the value of
3120 scm_boot_guile_1. This function doesn't return a value;
3121 scm_boot_guile_1 doesn't return a value (or return at all).
3123 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3126 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3127 compile. I have a feeling this function is a bad idea anyway ---
3128 one should always test for features, not systems.
3130 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3131 semicolons. Only pure luck kept this from being noticed earlier.
3133 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3135 * socket.c (scm_recvfrom): Added missing semicolon.
3137 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3139 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3140 the buffer and start and end positions for scsh networking
3143 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3145 * configure.in: Revert previous change to this file; the problem
3146 is due to transient automake weirdness.
3147 * configure: Rebuilt.
3149 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3150 PLUGIN/guile.libs. configure generates the latter from the former.
3151 * Makefile.in: Rebuilt.
3153 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3154 need this if we install scripts, like guile-snarf.
3155 * configure: Rebuilt.
3157 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3159 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3161 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3163 * socket.c (scm_addr_vector): fix faulty scm_listify.
3165 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3167 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3168 style block comment is no longer considered an error.
3170 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3172 * PLUGIN/guile.libs.in: New file.
3173 * PLUGIN/guile.libs: Removed from repository.
3174 * configure.in: Create PLUGIN/guile.libs from
3175 PLUGIN/guile.libs.in. This is for including additonal libraries
3176 needed for dynamic linking.
3177 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3178 instead of PLUGIN/guile.libs.
3180 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3182 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3184 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3185 occurrences of the given element from the list, not just the
3186 first. This is how the Emacs Lisp functions behave, how the
3187 analogous Common Lisp functions behave, and (I believe) how the
3188 older Maclisp functions worked. I realize that this change may
3189 break code, but it seemed better to break it before the Guile
3192 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3193 Their prototypes were already present in gc.h, but they weren't
3195 (scm_init_storage): Initialize scm_protects.
3196 * root.c (scm_protects): New element of scm_sys_protects.
3198 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3200 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3202 * libguile.h: Added #include "libguile/net_db.h".
3204 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3205 30 change. That file is only meant for communication between the
3206 configuration process and load.c. If code linked against libguile
3207 wants to get at the paths mentioned in libpath.h, it can call
3208 functions declared in load.h.
3210 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3212 * libguile.h: Removed #include "libguile/fdsocket.h"
3214 * net_db.c: Added #include <sys/socket.h>.
3216 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3218 * filesys.c (scm_input_waiting_p): use select in preference to
3219 FIONREAD, since the latter doesn't detect EOF.
3220 Throw error if neither select nor FIONREAD available.
3222 * socket.c (scm_connect): take a port, not a fd object.
3223 (scm_fill_sockaddr): throw an error if fam is not recognised.
3224 (scm_bind): use scm_fill_sockaddr.
3225 (scm_listen): take a port, not a fd object.
3226 (scm_accept): take and return a port. return #f in the car if
3227 address can't be got
3228 (scm_sock_fd_to_port): new procedure.
3229 (scm_socket): use scm_sock_fd_to_port.
3230 (scm_addr_vector): throw error if unrecognised address type.
3231 take an extra argument with the calling procedure name.
3232 (scm_getsockname): take a port. return #f if address can't be got.
3233 (scm_getpeername): take a port. return #f if address can't be got.
3234 (scm_recvfrom): take a port. return #f for address component if can't
3236 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3237 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3239 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3241 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3242 use separate data pointers, to allow them to be designed
3243 independently and reused.
3244 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3245 Renamed from catch_body, catch_handler, and uncaught_throw; made
3247 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3249 (scm_catch): Use the above.
3250 (scm_throw): Don't bother printing a message for an uncaught
3251 throw; we establish a default handler in init.
3252 * throw.h (scm_internal_catch): Prototype updated.
3253 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3255 (struct scm_body_thunk_data): New structure, used as data
3256 argument to scm_body_thunk.
3257 * init.c (struct main_func_closure): New structure, packaging up
3258 the data to pass to the user's main function.
3259 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3260 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3261 scm_internal_catch to establish a catch-all handler, using
3262 scm_handle_by_message. This replaces the special-case code in
3264 (invoke_main_func): Body function for scm_internal_catch; invoke
3265 the user's main function, using the main_func_closure pointer to
3266 decide what to pass it.
3267 * root.c (struct cwdr_body_data): Remove handler_proc member.
3268 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3269 (cwdr_handler): Removed.
3271 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3273 * socket.h (SCM_P): update bind prototype.
3274 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3275 include "feature.h".
3276 (scm_socket): return a port, not a file descriptor object.
3277 include "fports.h" and <unistd.h>
3278 (scm_bind): take a port, not a file descriptor object.
3279 take an extra argument for address args.
3281 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3282 INADDR_NONE, INADDR_LOOPBACK.
3284 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3286 * init.c: include net_db.h and not fdsocket.h.
3287 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3289 * Makefile.am: corresponding changes.
3290 * socket.h: renamed from fdsocket.h, fix names.
3291 * net_db.h: renamed from socket.h, fix names.
3292 * socket.c: renamed from fdsocket.c.
3293 remove _sys from procedure names.
3294 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3295 add "socket" to features list.
3296 * net_db.c: renamed from socket.c.
3297 remove _sys from procedure names.
3298 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3299 add "net-db" to features list.
3300 include "net_db.h". don't include <sys/socket.h> or
3303 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3305 * tags.h (scm_tags): Removed comma at end of last enumerator.
3307 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3309 Don't use GCC extensions to allocate space for debugging frames.
3310 (Here he goes again! Why do we put up with this?!)
3311 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3312 an scm_debug_info structure, not an in-line array of them. Add
3313 'info' member, to say how many vect elements we've used, for eval
3315 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3316 a new variable debug_info_end to mark the end of vect, instead of
3317 the address of the 'info' pointer itself.
3318 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3319 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3320 (SCM_APPLY): Explicitly allocate space for debug.vect.
3321 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3322 * stacks.c: Adjusted for new debug frame structure.
3323 (RELOC_INFO, RELOC_FRAME): New macros.
3324 (stack_depth, read_frames): Use them, and new scm_debug_frame
3325 element 'info', instead of magically knowing that eval frames have
3326 an info pointer sitting after vect.
3327 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3329 (scm_init_stacks): Formatting tweaks.
3331 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3333 Give GCC more control flow information, so it can be sure that
3334 variables aren't used uninitialized.
3335 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3336 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3337 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3338 scm_misc_error): Tell GCC that these functions never return.
3339 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3340 out the field type, call abort if SCM_ASSERT returns, to placate
3342 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3343 scm_wta ever returns. We can't handle this case anyway, and this
3344 gives the optimizer more information.
3345 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3346 scm_wta ever returns.
3348 In some cases, the code is fine, but GCC isn't smart enough to
3349 figure that out; this usually happens when one variable is only
3350 initialized and used when a particular condition holds true, and
3351 we know that condition will never change within a given invocation
3352 of the function. In this case, we simply initialize the variables
3353 to placate the compiler, hopefully to a value which will cause a
3354 crash if it is ever actually used.
3355 * print.c (scm_iprin1): Initialize mw_pos.
3356 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3357 * throw.c (scm_ithrow): Initialize dynpair.
3358 * unif.c (scm_uniform_vector_ref): Initialize cra.
3359 * struct.c (init_struct): Initialize prot.
3360 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3362 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3363 if EXPR contains no expressions.
3365 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3367 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3368 cause an infinite loop (???). So much for the algebraic
3369 equivalency of variable-sized arrays and alloca...
3371 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3373 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3374 a SCM boolean, not a C boolean.
3376 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3378 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3379 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3380 rules for raising scm_mtrigger. Previously, unfortunate but not
3381 unlikely circumstances could result in almost constant invokation
3382 of the gc. Now, this situations should be less likely, but they
3383 are not prevented completely.
3385 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3387 * numbers.c (scm_fuck): Procedure removed; looks like old test
3389 * numbers.h: Prototype removed.
3391 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3393 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3394 array to a pointer, to match my Nov 21 change in eval.c.
3396 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3398 * libguile.h: Added #include "libguile/backtrace.h", #include
3399 "libguile/stacks.h".
3401 * strings.c (scm_string scm_make_string scm_string_ref
3402 scm_string_set_x scm_string_equal_p scm_string_append):
3403 Bugfix according to scm patch from Aubrey Jaffer:
3404 Corrected long-standing
3405 (not (eqv? (integer->char 128)
3406 (string-ref (make-string 1 (integer->char 128)) 0)))
3407 bug found by John Kozak <jk@noontide.demon.co.uk>.
3409 * strports.c, strports.h: Make scm_eval_0str return the value of
3410 the last expression evaluated (previously, it returned void).
3412 * strports.c, strports.h: New function: scm_read_0str. Does what
3415 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3417 * simpos.c (scm_getenv): return #f if string can't be found in the
3418 environment instead of throwing an exception, for compatibility
3419 with numerous other systems.
3421 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3423 * Makefile.am (.c.x): Use guile-snarf.
3424 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3426 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3428 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3430 * backtrace.c (scm_display_error_message): Made non-static, and
3431 renamed from display_error_message.
3432 * backtrace.h (scm_display_error_message): Added extern decl.
3433 * throw.c (uncaught_throw): Use it to display the error message.
3435 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3437 * inet_aton.c: Use #if 0, not #ifdef 0.
3439 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3441 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3442 to convert the returned value.
3443 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3444 the offset argument.
3446 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3448 Add new interface to catch/throw, usable from C as well as
3450 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3451 (scm_internal_catch): New function, replaces...
3452 (scm_catch_apply): Deleted.
3453 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3454 mechanism which is a bit more code, but can be used nicely from C
3455 and implement the Scheme semantics as well.
3456 (scm_internal_catch): This is the replacement; it's named after
3457 the analogous function in Emacs.
3458 (scm_catch): Reimplemented in terms of the above.
3459 (struct catch_body_data, catch_body, catch_handler): New
3460 functions, used by scm_catch.
3461 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3462 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3463 support for new cwdr.
3465 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3468 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3470 * acconfig.h: Added DYNAMIC_LINKING symbol.
3471 * configure.in: Add option and checks for dynamic linking.
3472 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3473 dynl.h: New files for dynamic linking support.
3474 * Makefile.am (libguile_a_SOURCES):
3476 (modinclude_HEADERS): Added "dynl.h".
3477 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3479 * init.c (scm_boot_guile_1): Call
3480 scm_init_dynamic_linking to initialize dynamic linking support.
3482 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3484 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3485 (as we Schemers say). It needs to be global, so that I can tweak
3486 it for the proper operation of unexec.
3487 (scm_boot_guile_1_live): New variable, see above.
3489 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3491 * guile-snarf.sh: Removed.
3492 * PLUGIN/guile.libs: Added dependency for -lm.
3493 * acinclude.m4: Renamed from aclocal.m4.
3494 * PLUGIN/greet: Removed.
3495 * Makefile.am, aclocal.m4: New files.
3496 * configure.in: Updated for Automake.
3498 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3500 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3501 and not top_level_lookup_thunk_var.
3503 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3505 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3507 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3509 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3510 Scheme function, instead of syntax. Single argument is now a
3513 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3515 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3516 scm_ra_divide): Properly terminate statements passed as arguments
3517 to IVDEP macros. (Thanks to Bernard Urban.)
3519 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
3520 with non-constant sizes. (Thanks to Bernard Urban.)
3522 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3524 It's an "eval closure", not an "eval thunk." A thunk is a
3525 function of no arguments.
3526 * root.h (struct scm_root_state): Renamed
3527 top_level_lookup_closure_var from top_level_lookup_thunk_var.
3528 (scm_top_level_lookup_closure_var): Renamed from
3529 scm_top_level_lookup_thunk_var.
3530 * root.c (mark_root): Uses changed.
3531 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
3532 * init.c (scm_start_stack): Uses changed.
3533 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
3534 Change scheme-visible name to *top-level-lookup-closure* from
3535 *top-level-lookup-thunk*.
3537 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
3539 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
3540 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
3542 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
3544 * gc.c (struct scm_heap_seg_data): Doc fixes.
3546 * gc.c (scm_gc_sweep): Empty all segments' freelists before
3547 sweeping. Then, prepend each segment's free cells to its
3548 freelist, rather than wiping out the old value. (Thanks to Marius
3551 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
3552 scm_check_freelist, scm_debug_newcell): New functions and
3553 variables, for debugging freelist problems.
3554 * pairs.h (SCM_NEWCELL): New debugging version added.
3555 * gc.h (scm_debug_newcell): Added extern declaration, used by
3556 debugging version of SCM_NEWCELL.
3558 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3560 On some systems <libc.h> conflicts with <unistd.h>, and should not
3561 be #included at all.
3562 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
3563 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
3564 * configure.in: Call it.
3565 * posix.c, filesys.c: Use its results to decide whether or not to
3567 * configure, scmconfig.h.in: Rebuilt with autoconf and
3570 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3572 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
3573 pointer to the stdio stream before calling scm_setbuf0, so the
3574 latter will be able to retrieve it. I'm surprised this didn't
3575 segfault earlier. (Thanks to Christopher Lee.)
3577 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3579 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
3582 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3584 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
3585 number of stack narrowing specifier pairs. The first specifier in
3586 a pair controls inner border, the second the outer border. A
3587 number means cut that number of frames, a procedure object means
3588 cut until that object is found in operator position in a frame.
3590 * root.c (cwdr): Bugfix.
3592 * read.c: Recording of positions disabled by default.
3594 * procs.c (scm_closure_p): New function.
3596 * posix.c (scm_tmpnam): New function.
3598 * load.c: Added #include "throw.h".
3599 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
3602 * load.c, load.h (scm_read_and_eval_x): New function.
3604 * eval.c: Renamed debug option "deval" to "debug".
3606 (scm_eval_x): `eval!' is no longer accessible from the scheme
3607 level. Motivation: We can't allow operations which introduce
3608 glocs into the scheme level. Guile's type system can't handle
3609 these as data. Use `eval' or `read-and-eval!' as replacement.
3611 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
3612 SCM_CONSP since this is a macro!; Set vframe.prev to
3613 scm_last_debug_frame instead of 0. In this way we can look
3614 "above" the virtual start stack frame if we wish.
3615 (scm_debug_hang): New function: Useful for debugging Guile in
3616 certain tricky situations. Will probably be removed later...
3618 * debug.h: Changed semantics of debug option "backtrace". This
3619 option now only indicates whether we want automatic backtrace at
3622 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3624 * ports.c: #include "filesys.h"
3625 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
3627 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
3628 Motivation: This is system specific code which is related to file
3629 I/O. It also may use select. Added code by Gary Houston to
3630 detect presence of character in stdio buffers.
3632 * libguile.h: #include "libguile/libpath.h"
3634 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
3635 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
3636 SCM_SITE_DIR; Install libpath.h among the other include files.
3638 * load.c, load.h (scm_sys_package_data_dir): New function.
3640 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3642 * stacks.h: Bugfix: Don't use tail-array length field as stack
3643 length field! This screwed GC.
3645 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3647 * _scm.h: Added #ifndef around definition of macros min and max.
3649 * __scm.h: Added hooks for threads to plugin to in ints protection
3650 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
3651 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
3652 the main code in these macros duplicated and spread over multiple
3653 files. Renamed SCM_THREADS_SWITCHING_CODE ->
3654 SCM_THREAD_SWITCHING_CODE.
3656 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
3658 * snarf.h: New file.
3659 * guile-snarf.sh: New file.
3660 * Makefile.in (inner_h_files): Added snarf.h
3661 (ancillary, install, uninstall, distclean): Added actions for
3663 (.c.x): Use guile-snarf.
3664 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
3665 (gen_c_files): Note that these depend on guile-snarf.
3666 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
3667 now in "snarf.h". Added #include "snarf.h" to get them.
3668 * libguile.h: Added #include "snarf.h".
3669 (Patches applied and tweaked by Jim Blandy.)
3671 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3673 * socket.c: Use K&R style declaration for 'close'; the GNU coding
3674 standards suggest against providing prototypes for system
3675 functions. Thanks to Greg Troxel.
3677 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3679 * strports.c (scm_eval_0str): New function.
3680 #include "read.h", to get prototype for scm_read.
3681 * Makefile.in (strports.o): Update dependencies.
3682 * strports.h: New prototype.
3684 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
3685 scheme name from "int?" to "integer?". It seems to do the job.
3686 * numbers.h: Rename prototype too.
3687 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
3690 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
3691 scm_num_eq_p): Rename these according to R4RS conventions: call
3692 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
3693 to making libguile R4RS compliant without ice-9...
3695 * load.c (scm_sys_search_load_path): Search for files under all
3696 extensions listed in the %load-extensions variable. If FILENAME
3697 is absolute, return it unchanged, without searching the load path.
3698 (scm_loc_load_extensions): New variable, pointing to
3699 %load-extensions' value cell.
3700 (scm_init_load): Initialize it, and the value it points to.
3701 (scm_primitive_load_path): Improve error reporting.
3703 * load.c (scm_loc_load_hook): New variable, pointing to value cell
3704 of new Scheme variable %load-hook.
3705 (scm_primitive_load): Apply %load-hook to filename.
3707 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
3709 * configure.in: add tests for figuring out whether buffered data
3710 is available in a FILE structure, which is needed by char-ready.
3712 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
3715 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
3716 exceptions using misc_error instead of syserror. It seems a bit
3717 odd to throw an exception if a string can't be found in the
3718 environment, but it's consistent with open-file, stat etc.
3719 (simpos.h): remove sys_ from getenv.
3721 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
3722 occurs, throw an error instead of returning errno. Return value
3724 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
3726 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
3728 * filesys.c (scm_stat2scm): derive file type and permissions from
3729 the stat mode and append them to the returned vector.
3730 There isn't much overhead in doing this and it avoids the need to
3731 work with S_IRUSR et al. in Scheme.
3732 Define symbols scm_sym_regular etc.
3733 (scm_init_filesys): don't intern S_IRUSR etc.
3735 * load.c: change s_try_load and s_try_load_path to s_primitive_load
3736 and s_primitive_load_path.
3738 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
3740 * error.h: don't declare error symbols. prototype for scm_misc_error.
3742 * stackchk.c (scm_stack_overflow_key): defined here instead of in
3745 * error.c: use SCM_SYMBOL to set up error keys.
3746 scm_misc_error: new procedure.
3748 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3750 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
3751 between `#!' and `!#' is ignored.
3752 (skip_scsh_block_comment): New function.
3754 * feature.c (scm_set_program_arguments): New argument, FIRST.
3755 * feature.h: Update prototype.
3756 * init.c (scm_boot_guile_1): Pass new argument to
3757 scm_set_program_arguments.
3759 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3761 * init.c (scm_start_stack): Don't initialize scm_progargs here.
3762 (scm_boot_guile): Call scm_set_program_arguments here, later than
3763 the old initialization.
3765 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
3766 initialization procedure.
3767 - Delete in, out, err arguments; there are other perfectly good
3768 ways to override these when desired.
3769 - Delete result argument; this function shouldn't ever return.
3770 - Rename init_func argument to main_func, for less confusion.
3771 - Delete boot_cmd argument; main_func is more general.
3772 -Add 'closure' argument, to help people pass data to main_func
3773 without resorting to global variables.
3774 - Abort if reentered; don't bother returning an error code.
3775 - Call scm_init_standard_ports to set up the default/current
3776 standard ports; no need to pass them to scm_start_stack.
3777 - Remove code to evaluate the boot_cmd, and start the repl; let
3778 the user do something like that in main_func if they want.
3779 - Remove code to package up a return value; main_func can do any
3781 - Call exit (0), instead of returning.
3782 (scm_start_stack): Don't initialize the I/O ports here; that's
3783 weird. Delete in, out, err arguments. Move guts to
3784 scm_init_standard_ports, scm_stdio_to_port.
3785 (scm_init_standard_ports): New function, to set up current and
3786 default standard ports.
3787 (scm_start_stack, scm_restart_stack): Make these static.
3788 * init.h (scm_boot_guile): Adjust declaration.
3789 (scm_start_stack, scm_restart_stack): Remove externally
3790 visible declarations for these.
3791 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
3793 * fports.c (scm_stdio_to_port): New function. Its guts used to be
3794 written out several times in scm_start_stack.
3795 * fports.h: New declaration for the above.
3797 * feature.c (scm_set_program_arguments): New function.
3798 * feature.h: New declaration for the above.
3800 * ports.c: Formatting tweak.
3802 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
3804 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
3805 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
3806 for obtaining the address of a car or cdr field. Motivation:
3807 &SCM_CXR make assumptions about the internal structure of the
3810 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
3811 Motivation: see SCM_CXRLOC.
3813 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
3814 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
3815 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
3816 Motivation: Safer use. Some other macros are defined in terms of
3817 these operations. If these are defined using the SCM_SETCXR
3818 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
3819 to inefficiency and an <e1> with side-effects could potentially
3820 break. Also, these particular operations are heavily utilized in
3821 the garbage collector. In unoptimized code there will be a
3824 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
3825 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
3826 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
3827 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
3828 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
3829 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
3830 vports.c: Cleaned up use of pairs: Don't make any special
3831 assumptions about the internal structure of selectors and
3832 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
3833 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
3834 (Among other things, this change makes it easier to build Guile
3835 with certain compilers which have problems with casted lvalues.)
3837 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3839 * stacks.c: Improve selection of relevant stack frames when making
3840 a stack object. Introduce one level of indirection in the stack
3841 object to make it possible to "narrow" to a certain region of the
3842 stack. This facilitates making use of more clever algorithms (not
3843 implemented) for selecting relevant frames and gives a cleaner
3844 design since selection of frames can be done independently of
3845 extraction of frames from the real stack.
3846 (scm_stack_id): Also take #t as argument which means look at
3849 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
3850 Turn n_tail into an integer directly representing current number
3851 of frames in stack. Add field tail.
3853 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
3855 * debug.c (scm_make_memoized): Made it available at scheme level.
3856 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
3857 SCM_NIMP before applying heavier predicates in argument checking.
3858 (scm_local_eval): Also take memoized object as argument.
3860 * backtrace.c (scm_display_error): Just a safety measure: Stacks
3861 aren't created with zero length, but should such a strange
3862 creature suddenly turn up...
3864 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
3866 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
3867 `del', for the sake of C++ compilers. (Patch applied by JimB.)
3869 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
3871 * variable.c (scm_make_variable): Make the name hint optional, as
3873 (anonymous_variable_sym): Renamed from variable_sym. All uses
3876 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
3877 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
3878 of scm_primitive_load_path was also changed to
3879 "primitive-load-path", from "%try-load-path". Callers changed.
3880 We'd like to respect the convention that a function named
3881 "try-mumble" should behave just like the function called "mumble",
3882 but return #f instead of signalling some error.
3883 * load.h: Rename prototypes.
3885 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3887 * print.c (make_print_state, grow_print_state), print.h: Modified
3888 the print state representation: Don't use a tail array for
3889 recording of circular references. Resizing of the print state
3890 structure invalidates the print state pointer. To avoid passing
3891 around an indirect print state reference to all printing
3892 functions, we instead let the print state reference a resizable
3895 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3897 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
3898 Don't crash when passed an improper list terminated by a
3899 non-immediate value.
3901 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
3903 Allocate data for structures on an eight-byte boundary, as
3904 required by the tagging system.
3905 * struct.c (alloc_struct): New function.
3906 (scm_make_struct, scm_make_vtable_vtable): Call it.
3907 * struct.h (scm_struct_n_extra_words): Bump to 3.
3908 (scm_struct_i_ptr): New "field".
3909 * gc.c (scm_gc_sweep): When we need to free the data, use the
3910 information stored by alloc_struct to find the beginning of the
3911 block allocated to the structure, so we can free it.
3913 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3915 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
3918 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
3919 (scm_debug_info): New member: id.
3921 * stacks.c: Stacks are now represented as structs; Stacks have an
3922 id given to them by `start-stack'.
3923 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
3925 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
3926 Changed stack representation.
3928 * debug.c (scm_procedure_name): Try procedure property `name' for
3929 compiled closures aswell.
3931 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
3933 * eval.c: scm_i_name moved to gsubr.c
3934 (scm_m_define): Record names of all kinds of procedure
3935 objects. (Earlier, only closures were recorded.)
3937 * procprop.h: Added declaration of scm_i_name.
3939 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
3940 (scm_make_gsubr): Record names of compiled closures.
3942 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3944 * debug.c, debug.h: Removed obsolete code.
3946 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
3947 stacks.c: Renamed regs --> scm_contregs.
3949 * print.c (scm_free_print_state): Cleanup print state before
3950 returning it to pool. It is better to do it here than in
3951 scm_prin1 since scm_prin1 is called often.
3953 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
3954 s_set_source_property_x): Check that first argument is a pair or a
3957 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
3958 scm_i_line, scm_i_column and scm_i_breakpoint global.
3960 * init.c: Added #include "backtrace.h" and #include "stacks.h".
3961 (scm_boot_guile_1): Added calls to scm_init_backtrace and
3964 * debug.h: Added debug object smob declaration and macro
3967 * configure.in: Build with backtrace.o and stacks.o if debug
3970 * Makefile.in: Added entries for new files: backtrace.c,
3971 backtrace.h, stacks.c and stacks.h.
3973 * symbols.c (scm_sym2ovcell): Fixed documentation.
3975 * _scm.h (min, max): Added.
3977 * async.c: Moved `min' macro to _scm.h.
3979 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
3980 SCM_BACKTRACE_INDENT.
3982 * eval.c: Added new debug options `maxdepth' and `indent'.
3984 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
3986 * print.h: Added selector SCM_PRINT_STATE.
3988 * print.c: New functions: scm_make_print_state,
3989 scm_free_print_state.
3991 * print.h: Added declarations for scm_make_print_state,
3992 scm_free_print_state.
3994 * debug.c (scm_m_start_stack): New acro.
3996 * debug.h: Small cleanup.
3998 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4001 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

4021 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
4022 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
4023 declare functions with prototypes. (Patch thanks to Marius
4026 More prototype-related changes from Marius Vollmer:
4027 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4028 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4029 * ports.h (ptobfuns): Added prototypes. This means some casting in
4031 * fports.c: Added casts for initializations, since the functions
4032 are defined to take FILE * as their stream argument, not SCM.
4033 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4034 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4035 to `char *str_data' to conform to prototype.
4037 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4039 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4041 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4043 * stime.c, stime.h: use SCM_P method.
4045 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4047 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4048 be given at least two arguments. Insist that lst's last element
4049 be a list, but don't make any requirements of its predecessors.
4051 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4053 * eval.c (scm_nconc2last): Revert last change; there seems to be
4054 other stuff going on here.
4056 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4058 * eval.c (scm_nconc2last): Make sure that each element of lst
4059 (which is a list of argument lists, except for the tail) is a
4060 proper list, i.e., finite and terminated by '().
4062 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4064 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4067 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4068 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4071 * vectors.c (scm_make_vector): Fill vectors with the undefined
4072 value, to help make Guile Scheme code more portable to other
4075 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4076 * symbols.h, tags.h: Doc fixes.
4078 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4080 * async.c (scm_take_signal): Doc fixes.
4082 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4084 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4085 want to subtract it from the modulus; we just want to leave it
4088 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4090 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4093 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4095 * throw.c (scm_catch_apply): Finished implementation of
4098 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4100 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4102 (scm_init_filesys): set "i/o-extensions" feature.
4105 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4107 * Makefile.in (root.o): Correct dependencies.
4109 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4111 * Makefile.in: Added dependency entry for root.o.
4113 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4114 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4116 * init.c (scm_start_stack): Set initial root continuation number
4119 * procs.c: New function: scm_thunk_p.
4121 * procs.h: Added declarations of scm_thunk_p.
4123 * root.c: Renamed `call-with-new-root' -->
4124 `call-with-dynamic-root'.
4125 (cwdr): Removed allocation of new root state. This should be done
4126 separately by use of scm_make_root.
4127 (scm_apply_with_dynamic_root): New function: Does what it
4128 sounds like. Needed when spawning threads.
4130 * root.h: Added member last_debug_frame to root state.
4131 Added #include "libguile/debug.h"
4133 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4134 arguments. The motivation is that code in root.c needs catch
4135 functionality, and we want to avoid code duplication.
4136 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4137 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4138 handlers that run without popping the stack into the dynwind
4141 * throw.h: Added prototypes for scm_catch_apply and
4144 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4146 * root.h (scm_root, scm_set_root): Decouple thread support details
4147 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4148 SCM_SET_THREAD_LOCAL_DATA.
4150 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4151 and tortoise scanning loop.
4153 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4155 * Makefile.in: Rebuild dependencies.
4157 * libguile.h: #include "libguile/print.h" before "smob.h", since
4158 the latter uses the print_state structure.
4160 * throw.c (scm_ithrow): Use the correct variable when checking to
4161 see if a given element of scm_dynwinds is a valid catch.
4163 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4164 structure, abort; don't just silently ignore the garbage.
4166 * _scm.h: #include "print.h" here, since it seems to be used just
4168 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4169 strports.c, unif.h: Don't #include "print.h".
4171 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4173 * feature.h (scm_loc_features): Removed external declaration.
4174 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4176 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4178 * feature.c (scm_init_feature): Added threads feature (needs to be
4179 initialized here, since features doesn't exist when
4180 scm_init_threads is called).
4182 * libguile.h: Added #include "libguile/../threads/threads.h".
4183 (This is a kludge to get thread support working. This should be
4186 * configure.in, acconfig.h: Added flags for thread support.
4188 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4191 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4192 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4195 * _scm.h: Added conditional #include "threads.h"
4197 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4198 SCM_THREADS_SWITCHING_CODE.
4200 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4201 allocate the basic dynamic root object.
4202 (scm_boot_guile): Added call to scm_init_root.
4204 * root.c, root.h: Added root smob.
4205 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4206 functions: Implements dynamic roots mostly according to spec in
4207 SCM manual. Main difference is that the second argument is a
4208 throw handler rather than an error "thunk".
4210 * root.h: Added declaration of scm_init_root.
4212 * root.c: Added #include "genio.h", #include "smob.h", #include
4213 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4215 (scm_init_root): Added #include "root.x".
4217 * throw.c: Added #include "stackchk.h"
4218 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4219 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4220 can be used in scm_call_with_new_root; Added reenabling of stack
4221 checking when catching a throw.
4223 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4225 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4227 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4228 element is not found, as per R4RS.
4230 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4232 * list.c: Doc fixes throughout.
4234 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4236 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4237 declare the char * to be const. Avoids a warning in rgx.c.
4239 * ports.h: spelling fix.
4241 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4244 * load.c (scm_sys_try_load_path): throw an error if file not found
4245 (like it says it in NEWS).
4247 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4249 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4250 PROPS slot to '(), not #f; it's an empty alist.
4252 * throw.h, throw.c: Use SCM_P instead of #if hair.
4254 Remove special support for uncaught throws; see throw.c for
4256 * throw.c (uncaught_throw): New function.
4257 (scm_ithrow): Call uncaught_throw if we don't find a throw
4258 target; don't mess with scm_bad_throw_vcell.
4259 (scm_bad_throw_vcell): Variable deleted.
4260 (scm_init_throw): Don't initialize it.
4262 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4265 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4267 * numbers.c (scm_istr2int): If the number is short (as most
4268 numbers are), just call scm_small_istr2int to deal with it.
4269 (scm_small_istr2int): New function, created by un-#ifdefing the
4270 non-bignum version of scm_istr2int and renaming it.
4272 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4274 * load.c (scm_sys_try_load): don't check whether value returned
4275 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4276 Change the Scheme name from %try-load to primitive-load.
4278 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4279 Can avoid passing a message, allowing it to be derived in the
4280 error handler (e.g., if we want to throw to the key both from
4283 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4285 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4286 references now have a new appearance which is more compact and
4287 also gives a clue about what the target of the reference is.
4288 By setting parameters in the print state, more fancy printing can
4289 be achieved. This is used by the (not yet commited) backtrace
4292 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4294 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4297 * print.c: Added #include "struct.h". Removed function
4300 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4301 scm_iprin1. Removed prototype for scm_prlist.
4303 * arbiters.c (prinarb),
4304 async.c (print_async),
4305 debug.c (prindebugobj, prinmemoized),
4306 eval.c (prinprom, prinmacro),
4307 filesys.c (scm_fd_print, scm_dir_print),
4309 mallocs.c (prinmalloc),
4310 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4311 smob.h (scm_smobfuns),
4312 srcprop.c (prinsrcprops),
4314 unif.c, unif.h (scm_raprin1, rapr1),
4315 variable.c (prin_var): Changed argument `int writing' to
4316 `scm_print_state *pstate'.
4318 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4319 that it will be called before scm_init_print.
4321 * print.c (scm_prin1): Print states are now allocated when calling
4322 scm_prin1 and then passed around to all printing functions as an
4323 argument. A cache `print_state_pool' enables reuse of print
4325 (scm_make_print_state): New function.
4326 (scm_iprin1): Adaption to print states.
4327 (scm_iprlist): An initial "hare and tortoise" scan brings down
4328 time complexity to O (depth * N). (Better time complexity will be
4329 achieved when the printing code is completely rewritten.)
4331 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4333 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4334 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4335 it gets done whether or not the cache variable has a value.
4337 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4339 Distinguish #f and ().
4340 * __scm.h: #undef SICP.
4341 * pairs.h (SCM_EOL): Delete this definition, equating it with
4343 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4344 the value it used to have. Doc fixes, too.
4346 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4348 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4349 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4350 Lord's implementation of structs, allowing for tail arrays as
4351 described in the manual. Also fixed some bugs. (Both the interface
4352 and the implementation should be improved.)
4354 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4356 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4357 People who whish to see the source can do `(print-enable 'source)'.
4358 Removed #ifdef DEBUG_EXTENSIONS.
4360 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4362 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4363 integer (assuming for now accepting an integer is a good thing).
4365 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4366 %S will be used instead for write'ing arguments.
4368 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4369 asserts. fix a few other asserts.
4370 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4371 scm_uniform_vector_ref, scm_array_set_x,
4372 scm_dimensions_to_unform_array): change args in
4373 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4374 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4375 scm_substring_fill_x): likewise.
4376 gsubr.c (scm_gsubr_apply): likewise.
4377 eval.c (SCM_APPLY): likewise.
4379 * eval.c (4 places): replace scm_everr with lgh_error or
4382 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4383 scm_memory_error): new procedures.
4384 scm_everr: deleted. can use scm_wta, dropping first two args.
4385 scm_error: convert NULL subr to SCM_BOOL_F.
4387 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4390 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4393 * error.c, error.h: new error keys: scm_arg_type_key,
4394 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4396 scm_wta: reimplement using lgh_error instead of scm_everr.
4398 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4400 * gdbint.c: scm_lread now has one more argument.
4402 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4403 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4404 loading source from non-file ports, which, e. g., happens when
4405 using the Emacs interface).
4407 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4410 * read.c: Added code for recording of positions of source code
4411 expressions; New functions: recsexpr, scm_lreadrecparen;
4412 _scm_make_srcprops --> scm_make_srcprops
4413 (scm_flush_ws): Removed updating of positions counters. This work
4414 is already done by scm_gen_getc
4416 * read.h: Added prototype for scm_lreadrecparen
4418 * print.c: Added #include "alist.h"
4420 * eval.c: Added #include "hash.h"
4422 * eq.c: Added #include "ramap.h"

4428 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4429 --> scm_make_srcprops
4431 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4432 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4433 function calls in the definition of the whash access macros.
4435 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4437 * init.c (scm_boot_guile): Add level of indirection to
4438 scm_boot_guile_1() to ensure that stack base pointer is properly
4439 initialized. There was no guarantee that variable i was the
4440 highest/lowest variable on stack (i.e. the call frame of
4441 scm_boot_guile was not completely protected from gc).
4443 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4445 * ports.h (scm_port_table): put back file_name, it will be used to
4446 support debugging. Undo related changes in fports.c, ioext.c,
4449 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4451 * ports.h (scm_port_table): remove file_name member for now, it seems
4453 * fports.c (scm_open_file): don't set file_name in PTAB.
4454 (prinfport): don't use file_name in PTAB.
4455 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4456 * ports.c (scm_add_to_port_table): don't intialize file_name.
4457 (scm_port_file_name): remove for now.
4458 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4460 * fports.h (scm_mkfile): prototype deleted.
4461 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4463 * debug.c, unif.c: use scm_out_of_range instead of
4464 wta for range errors (ASSERT still needs work).
4466 * error.c, error.h (scm_out_of_range): new procedure.
4468 * error.c, error.h (scm_out_of_range_key): new key.
4470 * posix.c (scm_sync): #else was missing.
4472 * error.c, error.h: append _key to names scm_num_overflow and
4475 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4476 of consing an empty list.
4477 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4478 of macros, saves code and string space.
4479 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4480 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4481 lower case. Rename scm_syserror_m to scm_syserror_msg.
4482 error.h: prototypes for new procedures.
4484 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4486 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4488 * error.c, error.h: setup scm_num_overflow key.
4490 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4491 Remove definition of SCM_OVSCM_FLOW.
4493 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4495 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4496 explicit message and args.
4498 * error.c, error.h, __scm.h: change system_error_sym to
4501 * error.c (system_error_sym): remove leading %% from the Scheme name
4504 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4506 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4508 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4509 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4510 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4511 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4512 renamed. (These were introduced by unsupervised name
4515 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4517 * print.c: Added code for detection of circular references during
4518 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4519 a hook for printing of closures (accessible via print options).
4520 This leads to a split of calls to scm_iprin1 into two classes:
4521 elementary print operations (e. g. the code which prints a smob)
4522 still use scm_iprin1 while top level calls (like scm_display) use
4523 scm_prin1. scm_prin1 begins by clearing the data structure used
4524 to record reference information.
4526 * print.h: Added declarations of scm_prin1 and scm_prlist.
4528 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
4530 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
4532 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
4534 * error.c (err_head): scm_iprin1 --> scm_prin1
4536 * debug.c: Adjusted header comment.
4540 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4542 * strerror.c: Doc fix.
4544 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4546 * gdbint.c (gdb_read): Now possible to run during GC.
4547 (unmark_port, remark_port): New functions.
4549 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
4551 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
4552 of allocating a new string object. Also, increase size by
4553 the factor 2 instead of 1.5.
4555 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
4557 * __scm.h (SCM_P): Corrected to run under traditional C.
4559 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
4562 * async.c: Calls to scm_sysintern corrected.
4564 * async.h (scm_async_clock): Redundant declaration removed.
4566 * continuations.c (scm_dynthrow): Redundant declaration removed.
4568 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
4569 Definition typos corrected.
4571 * debug.h: Missing declarations of functions in debug.c added
4574 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
4575 Missing declarations to functions in eval.c added.
4577 * filesys.c: Possibly uninitialized variable rv.
4579 * gc.h (scm_object_addr, scm_unhash_name): Missing
4580 declarations of functions defined in gc.c added.
4582 * genio.c: Possible typos str_data -> wstr_data. ???
4584 * genio.c: Possibly unintended shadowing of local variable
4585 `int c' (gotos out of scope of inner `c'). ???
4587 * init.c: Uninitialized `SCM last' may be used.
4589 * ioext.h: (scm_sys_isatty_p): Typo.
4591 * list.h (scm_list_head): Missing prototype for function in
4594 * numbers.c (scm_two_doubles): Changed from extern to static
4595 (is used only within numbers.c).
4597 * numbers.h: Repeated declarations removed.
4599 * ports.h (scm_close_all_ports_except): Declaration for the
4600 function defined in ports.c added.
4602 * posix.h: Missing declarations added.
4604 * procs.h (scm_make_subr_opt): Missing declaration added.
4606 * socket.h (scm_sys_gethost): Missing declaration added.
4608 * socket.h: Redundant declarations removed (they are in fdsocket.h).
4610 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
4611 Missing declarations added.
4613 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
4615 * struct.c: Uninitialized variable `SCM answer' may be used.
4617 * unif.c (l2ra): Declaration prototype.
4619 * unif.c (scm_array_equal_p): Dummy definition removed (it is
4620 defined in ramap.c).
4622 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
4623 Redundant declarations removed (they are in ramap.h).
4625 * variable.h (scm_make_udvariable,
4626 scm_make_undefined_variable): Declaration corrected to
4627 correspond variable.c.
4629 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
4630 Missing declarations added.
4632 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
4634 * Makefile.in (distclean): Don't forget to delete fd.h.
4636 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4638 * fd.h.in, tags.h: Trivial cleanups.
4640 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
4641 marksweep.h just declared functions from gc.c.
4642 * gc.h, libguile.h: Don't #include "marksweep.h".
4643 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4644 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
4645 dependencies updated.
4647 * libguile.h: Don't #include "files.h"; it's been deleted.
4649 * files.c (scm_sys_delete_file): Moved to filesys.c.
4650 File is now empty; deleted.
4652 * filesys.c: scm_sys_delete_file is now here. Remove
4653 #if's; they seem to rely on remnants of an old portability
4654 regimen. If the problems come up again, solve them properly,
4655 using autoconf. Specifically: Don't test M_SYSV, and #define
4656 remove to be unlink if it's #defined; don't use remove just
4657 because HAVE_STDC_HEADERS is #defined.
4658 * filesys.h: Add declarations for scm_sys_delete_file.
4659 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4660 files.o, files.h, files.c, and files.x.
4661 * init.c: Don't #include "files.h", and don't call scm_init_files.
4663 Use SCM_P instead of PROTO; the latter intrudes on the user's
4665 * params.h: Deleted; definition of SCM_P moved to...
4666 * __scm.h: ... here, where it replaces PROTO macro.
4667 * libguile.h, smob.h: Don't #include "params.h".
4668 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
4669 smob.h: Fix prototypes accordingly.
4670 * Makefile.in: Update dependencies.
4671 (inner_h_files): Remove params.h.
4673 * gc.c: #include "gc.h"; every module should include its header,
4674 to let the compiler cross-check the declarations against the
4677 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
4678 simpos.h: #include "libguile/__scm.h".
4680 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
4682 * init.c: Don't forget to #include smob.h and init.h.
4683 * Makefile.in: Dependencies updated.
4685 * smob.h: Use PROTO instead of #if __STDC__.
4687 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
4689 * __scm.h: Doc fixes.
4691 * __scm.h, libguile.h: Use "quotes" in the #includes, not
4692 <angles>; this allows `make depends' to work properly.
4694 * libguile.h: #include smob.h and pairs.h before the others; they
4695 define typedefs used by other headers.
4697 C files should #include only the header files they need, not
4698 libguile.h (which #includes all the header files); the pointless
4699 recompilation was wasting my time.
4700 * Makefile.in (all .o dependency lists): Regenerated.
4701 * libguile.h: Don't try to get a definition for size_t here...
4702 * __scm.h: Do it here.
4703 * _scm.h: Since this is the internal libguile header, put things
4704 here that all (or a majority) of the libguile files will want.
4705 Don't #include <libguile.h> here; that generates dependencies on
4706 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
4707 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
4708 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

4801 * variable.c: Get "variable.h", "smob.h", "genio.h".
4802 * vectors.c: Get "vectors.h", "eq.h".
4803 * version.c: Get "version.h".
4804 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
4805 * weaks.c: Get "weaks.h".
4807 * stackchk.h: #include "libguile/debug.h",
4809 * print.h, read.h: #include "options.h", since everyone who uses
4810 either of these files will need that.
4812 * smob.h: #include "ports.h", "genio.h", and "print.h", since
4813 anyone who uses this file will need them to define the smob
4814 printing functions. Also, get markers.h, since people will need
4815 to #define the mark functions.
4817 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
4818 * ports.h: ... to here.
4820 * ports.h (scm_port_table_size): Explicitly give type as 'int';
4821 don't rely on archaic C default type rules.
4823 * fports.h: #include "libguile/ports.h", since you need that in
4824 order to parse this.
4826 * genio.h: #include "libguile/print.h", because you need that to
4827 parse this; don't bother #including "ports.h", since print.h gets
4830 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
4832 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
4833 this; it's now a reference to an element of *scm_root.
4835 * debug.h: Don't #include "options.h"; the compiler won't be able
4836 to find that once the headers are installed; instead, #include
4837 "libguile/options.h".
4838 * gc.h: Same, with marksweep.h.
4839 * mbstrings.h: Same, with symbols.h.
4840 * scmhob.h: Same, with _scm.h.
4841 * smob.h: Same, with params.h.
4843 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
4844 C files; there's no need for this, and it forces recompilations
4847 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
4849 * error.c (scm_error): declare scm_error_callback.
4851 * error.h: prototype for scm_error_callback.
4853 * __scm.h: define lgh_error.
4854 (SCM_SYSERROR): redefine using lgh_error.
4856 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
4858 * error.c (scm_error): new procedure.
4860 * error.h: prototype for scm_error.
4862 * Makefile.in (install): install scmconfig.h from the current
4863 directory, not $(srcdir).
4865 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4867 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
4868 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
4869 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
4870 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
4871 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
4872 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
4873 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
4874 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
4875 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
4876 vports.h, weaks.h: #include "libguile/__scm.h", not
4877 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
4878 dependencies are within libguile properly.
4880 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4882 * Makefile.in (.c.x): Simplify; there's no need to run this rule
4883 when scmconfig.h doesn't exist.
4885 * load.c (scm_sys_try_load): Correct spelling.
4887 * feature.c (scm_loc_features): Make this static.
4889 * Makefile.in (libpath.h): Omit trailing slash from path. We
4890 shouldn't require it of users, so why put it here?
4892 Move code to initialize and search %load-path from ice-9 to C
4893 code, so we can use the load-path to find the ice-9 boot code;
4894 this makes it easier to run Guile without installing it. See
4895 corresponding changes in guile/Makefile.in.
4896 * feature.c: Move stuff concerned with the load path to load.c.
4897 (scm_compiled_library_path): Deleted.
4898 Don't #include libpath.h here.
4899 * feature.h: Don't mention scm_compiled_library_path.
4900 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
4901 <sys/stat.h>, and <unistd.h> (if present).
4902 (R_OK): #define if the system hasn't deigned to.
4903 (scm_loc_load_path): New variable.
4904 (scm_init_load_path, scm_sys_search_load_path,
4905 scm_sys_try_load_path): New functions.
4906 (scm_init_load): Initialize scm_loc_load_path to point to the
4907 value cell of the Scheme %load-path variable.
4908 * load.h: Add declarations for scm_sys_search_load_path,
4909 scm_sys_try_load_path.
4910 * init.c: Call scm_init_load_path.
4911 * Makefile.in (feature.o, load.o): Dependencies updated.
4913 * load.c, load.h: Rewrite using PROTO macro.
4915 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4917 * gc.c (scm_cellp): New function: C predicate to determine if an
4918 SCM value can be regarded as a pointer to a cell on the heap.
4920 * gc.h: Added declaration of scm_cellp.
4922 * gdb_interface.h: New file: The GDB interface header from the GDB
4925 * gdbint.c: New file: GDB interface.
4927 * gdbint.h: New file: GDB interface.
4929 * libguile.h: Added #include <libguile/gdbint.h>.
4931 * init.c (scm_boot_guile): Added scm_init_gdbint.
4933 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
4934 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
4935 found if object files and source are kept separate).
4937 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
4939 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
4941 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
4943 * configure.in: Don't substitute the values of TCL_SRC_DIR and
4944 TK_SRC_DIR; they're not relevant any more.
4946 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
4947 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
4949 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
4951 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
4952 search path, so we can find the <libguile/MUMBLE.h> headers.
4954 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
4956 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
4957 implicit in the .c.o rule.
4958 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
4961 Put the library path in a header file, instead of passing it on
4962 the command line in every compilation.
4963 * Makefile.in (libpath.h): New target.
4964 (feature.o): Depend on libpath.h.
4965 (clean): Delete libpath.h.
4966 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
4967 * feature.c: ... #include "libpath.h" here.
4968 * .cvsignore: Ignore libpath.h.
4970 Don't install the unwashed masses of Guile header files in the
4971 main #include path; put most of them in a subdirectory called
4972 'libguile'. This avoids naming conflicts between Guile header
4973 files and system header files (of which there were a few).
4974 * Makefile.in (pkgincludedir): Deleted.
4975 (innerincludedir): New variable; this and $(includedir) are enough.
4976 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
4977 (installed_h_files): Divide this up. Now this variable lists
4978 those header files which should go into $(includedir) (i.e. appear
4979 directly in the #include path), and ...
4980 (inner_h_files): ... this new variable says which files appear in
4981 a subdirectory, and are referred to as <libguile/mumble.h>.
4982 (h_files): List them both.
4983 (install): Create innerincludedir, not pkgincludedir. Put
4984 the installed_h_files and inner_h_files in their proper places.
4985 (uninstall): Corresponding changes.
4986 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
4987 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
4988 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
4989 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
4990 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
4991 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
4992 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
4993 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
4994 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
4995 vports.h, weaks.h: Find __scm.h in its new location.
4996 * __scm.h: Find scmconfig.h and tags.h in their new locations
4997 (they're both "inner" files).
4999 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5001 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5003 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5005 * posix.c: Doc fixes.
5007 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5009 * socket.c: Don't include a prototype for inet_aton; just use a
5010 K&R style declaration, to avoid warnings but minimize the chance
5011 of conflicts with the system.
5013 On NextStep, <utime.h> doesn't define struct utime, unless we
5014 #define _POSIX_SOURCE before #including it.
5015 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5016 * acconfig.h: New comment text for above CPP symbol.
5017 * configure.in: Call it.
5018 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5020 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5022 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5023 testing for __EMX__.
5025 * posix.c: #include <libc.h>, if it exists.
5027 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5028 don't even know if the latter exists.
5030 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5031 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5032 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5034 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5036 (scm_init_posix): Use them when initializing the Scheme constants
5039 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5041 * Makefile.in (libdir, includedir, bindir): Use the
5042 autoconf-supplied values, instead of deriving them ourselves.
5043 (pkgincludedir, datadir, pkgdatadir): New variables.
5044 (install, uninstall): Put the header files in a special
5045 subdirectory, not in the main search path.
5047 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5048 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5050 * Makefile.in (IMPLPATH): Deleted; never used.
5052 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5053 on the Tcl/Tk source any more.
5054 (INCLUDE_CFLAGS): Remove references to the above.
5056 * Makefile.in (version.o): Corrected dependencies.
5058 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5060 * libguile.h: #include "version.h"
5062 * init.c (scm_boot_guile): Call scm_init_version.
5063 * gscm.c (gscm_run_scm): Call scm_init_version.
5065 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5066 GUILE_VERSION): AC_DEFINE these.
5067 (acconfig.h): #undef the above symbols.
5069 * Makefile.in (libobjs): Add version.o.
5070 (installed_h_files): Add version.h.
5071 (c_files): Add version.c.
5072 (gen_c_files): Add version.x.
5073 (version.o): New rule.
5074 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5075 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
5076 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,

5078 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5079 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5080 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5081 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5082 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5083 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5084 weaks.o): Add version.h to dependency lists.
5085 (markers.o): Remove duplicate rule.
5087 * version.h: New file.
5089 * version.c: New file.
5091 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5093 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5094 array; use it appropriately. Since GCC is quite happy to
5095 subscript functions, it never warned us about this; we should use
5096 -Wpointer-arith in the future. I guess we never tested
5099 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5101 * socket.c: Doc and copyright fixes.
5103 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5105 * debug.c: Fixed and improved gdb support.
5107 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5109 * socket.c: Added declaration of inet_aton to avoid compiler
5110 warning. (Hope this solution is correct.)
5112 * stime.c: Added declaration of ftime. (This is missing in
5115 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5117 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5119 * Makefile.in (c_files): add strerror.c.
5121 * strerror.c: new file from Emacs' sysdep.c.
5122 maybe configure should also check for sys_errlist.
5124 * configure.in (AC_REPLACE_FUNCS): add strerror.
5126 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5128 * debug.c (scm_init_debug): Added initialization for
5129 scm_evaluator_traps.
5131 * debug.h, debug.c: Various name changes.
5132 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5133 "debug-options-interface". See commentary in options.c.
5135 * options.h, options.c: Options now have documentation strings.
5136 Also added a long explanatory commentary.
5138 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5141 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5142 last_debug_info_frame is now updated in all cases.
5144 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5147 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5149 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5150 Added option STACK_CHECKING.
5152 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5154 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5156 * __scm.h: Removed symbols for debugging support.
5158 * acconfig.h: Added symbols for debugging support.
5160 * configure.in: Added user option for debugging support.
5161 --enable-debug will include the debugging code into libguile.a.
5163 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5164 scm_relocate_chunk_to_heap.
5166 * debug.c: New file: low-level debugging support. It also
5167 includes support for debugging with gdb. (The extensions to gdb
5168 are written by Per Bothner at Cygnus.)
5170 * debug.h: New file: low-level debugging support.
5172 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5173 argument pairs. Extensive modifications to the debugging
5174 evaluator. Added "SECTION:" commentaries to clarify what happens
5175 when, during double compilation. Renamed EVALIMP --> EVALIM.
5176 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5177 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5178 the beginning of the file. New procedure: scm_unmemocopy.
5179 Added some global state variables needed by the debugging
5180 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5181 check_entry, check_apply, check_exit, debug_options and
5182 evaluator_traps. New acro: undefine.
5184 * eval.h: Renamed EVAL --> XEVAL.
5186 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5187 --> scm_make_weak_key_hash_table.
5189 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5190 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5192 * libguile.h: Conditionally include debug.h
5194 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5195 scm_object_properties shouldn't return handle. `handle' now gets
5196 initialized in scm_set_object_properties_x. scm_object_properties
5197 doesn't any longer create an entry in scm_object_whash.
5199 * options.c: New file: handling of run time options.
5201 * options.h: New file: handling of run time options.
5203 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5205 * print.c: New procedure: scm_print_options
5207 * print.h: Defines for print options.
5209 * read.c: New procedure: scm_read_options
5211 * read.h: Defines for reader options.
5213 * root.h: Added scm_source_whash among scm_sys_protects.
5215 * srcprop.c: New file: source properties.
5217 * srcprop.h: New file: source properties.
5219 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5220 (Bug found by A. Green.)
5222 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5224 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5226 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5228 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5230 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5231 and should be called by the final client.
5233 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5235 * gc.h: Use the PROTO macro when declaring functions.
5236 * gc.c: Use the PROTO macro when declaring static functions.
5237 Remove the CPP hair around function definitions.
5239 * gc.c (scm_init_storage): Initialize scm_asyncs.
5241 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5242 preprocessor symbol; "__scm.h" is where it might get #defined.
5243 * __scm.h: Similar: #include <scmconfig.h> before testing
5246 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5248 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5250 * init.c (scm_boot_guile): Add init_func argument; call
5251 (*init_func) instead of calling scm_appinit; it's ucky to
5252 hard-code names for the user's procedures.
5253 * init.h (scm_boot_guile): Adjust declaration.
5255 * __scm.h (PROTO): New macro, for declaring functions with
5258 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5259 eliminate all the __STDC__ conditionals.
5260 (scm_boot_guile): Add declaration.
5261 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5262 Remove __STDC__ conditionals around function definitions; the
5263 declarations in init.h will provide the same information, more
5266 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5267 complain about it in the error message; the error message is
5268 adequate without that note, and there's nothing the user can do
5271 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5273 * Makefile.in (ancillary): Drop def.sed.
5275 * posix.c (scm_init_posix): Use numeric values, rather than
5276 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5277 F_OK. The symbols aren't available on some systems, and I'm
5278 pretty sure their values are fixed by common widespread practice.
5279 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5281 More functions unavailable on some systems.

5382 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5383 This is necessary on Ultrix, and doesn't hurt portability.

5387 Remove duplicate entries for markers.h and unif.h.

5393 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5395 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5396 every if must have an else, or else the whole command has a

5464 matter so long as it is non-0 (got rid of "* 4").
5466 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
5468 * gscm.h: gscm_mkarray eliminated (presumably was not being used

5475 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
5477 * ports.c: removed functions relating to the mapping between ports
5478 and descriptors. (That stuff is unix-specific and should be collected
5479 in a separate library).

5486 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
5487 handled correctly (SCM_FREEP was applied to them) -- test for
5488 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

5682 set the multi_byte flag correctly in symbols. This is wrong.
5683 intern_obbary_soft and msymbolize should take an extra parameter.

5685 The weird symbol syntax is also a bit bogus (emacs doesn't quite

5838 * lvectors.c (scm_lvector_set_x): avoid VELTS (VELTS (...)[..]) which
5839 can turn into an obscure gc bug.
5841 * chars.c (scm_char_p): fixed PROC call.
5843 * gscm.h (gscm_vset): use scm_vector_set_x not (the missing)
5846 Tue Jan 23 13:29:40 1996 Tom Lord <lord@beehive>
5848 * elisp.c (new file): dynamic scoping and other bits for
5849 elisp. Don't use this yet unless you specificly want to
5850 hack on elisp emulation.
5852 * dynwind.c (scm_dowinds): When entering or leaving a dynamic
5853 scope created by scm_with_dynamic_bindings_operation_x, swap
5854 the bindings of that scope with the corresponding globals.
5856 * continuations.c (scm_make_cont): when a continuation is captured,
5857 relocate the continuation stack chunks registered on the wind chain
5860 Sun Jan 21 19:31:17 1996 Tom Lord <lord@beehive>
5862 * eval.c (SCM_CEVAL): if the function position evaluates
5863 to a macro, process it accordingly. (Previously, macros were
5864 handled only if the function position was a symbol naming a
5865 variable bound to a macro).
5867 Sat Jan 20 23:21:37 1996 Tom Lord <lord@beehive>
5869 * eval.c (scm_m_set): allow multi-variable set! like
5872 Wed Dec 6 02:40:49 1995 Tom Lord <lord@beehive>
5874 * ports.h fports.c vports.c marksweep.c gc.c strports.c: moved the
5875 STREAM of ports into the port table and replaced it with a
5878 * repl.c (iprin1): added tc7_mb_string -- same as tc7_string.
5880 * marksweep.c (scm_gc_mark): added tc7_mb_string -- same as tc7_string.
5882 * mbstrings.c (new file): functions on multi-byte strings.
5884 * tags.h (scm_typ7_string, scm_typ7_mb_string): added a tag
5885 for multi-byte strings. Moved the string tag.
5887 * chars.h chars.c repl.c (many functions): made scm_upcase and
5888 scm_downcase functions that are safe for extended character sets.
5890 Changed the range of integer->char.
5892 Changed the type of SCM_ICHR.

5901 * guile.c (gscm_is_gscm_type): New function. (Without this how will we
5902 know that it's safe to pass an object to gscm_get_type?)
5903 (gscm_get_type): Fix tyop in error message.
5905 * variable.c (scm_variable_ref): fixed assertion test.
5906 (Robert STRANDH <strandh@labri.u-bordeaux.fr>)
5908 * gscm.h: fixed several prototypes, notably gscm_vref.
5909 Add gscm_is_eq and temporarily commented out gscm_eq (see
5910 the note in gscm.h near gscm_eq if this change effects your

5914 * pairs.c (scm_obj_length): see next entry.
5916 * gscm.h (gscm_obj_length): A way to get an integer

5921 (William Gribble <grib@arlut.utexas.edu>)
5923 * Makefile.in (X_CFLAGS): defined.
