1 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3 * options.c (scm_options): Bugfix: Allow empty list of options!
5 * debug.c, debug.h (scm_single_step): Removed.
6 (scm_with_traps): New procedure. This procedure could easily be
7 written in Scheme but needs to be highly optimized.
9 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
11 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
12 Check SCM_TRAPS_P before trapping.
14 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
16 Changes to avoid signed/unsigned comparison warnings.
17 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
18 (scm_gc_sweep): Make n and j local to the blocks they're used in,
19 so they can have appropriate types for each application. Make i
20 signed. Use initializers in some spots. I'll probably pay for
22 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
23 (scm_must_realloc): Make nm unsigned.
24 (init_heap_seg): Make new_seg_index and n_new_objects signed.
25 (scm_init_storage): Use prototype-style definition, and make the
27 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
28 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
30 * filesys.c (scm_readlink): Make local vars rv and size ints, to
31 avoid signed/unsigned comparison warnings, and because the return
32 value of readlink may be -1. Don't bother casting the third
35 * filesys.c (scm_dirname, scm_basename): Move these to their own
36 page, at the end of the file.
37 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
39 * eval.h (scm_eval_options_interface): Add external prototype for this.
40 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
42 * eval.c (scm_lookupcar1): Make this static.
44 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
45 Make these prototype declarations, not K&R-style.
47 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
48 unsigned comparison warning.
50 * appinit.c: File removed. It had a single function in it, empty,
51 whose reason for existence is explained in no documentation or
52 comment. I think it's there as a default for some Tcl-style
53 initialization, but Tcl abandoned that approach a while ago.
54 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
55 (BUILT_SOURCES): Remove appinit.x.
56 * Makefile.in: Regenerated.
58 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
60 * Makefile.in: Regenerated using the last public version of
61 automake, not the hacked Cygnus version.
63 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
66 * Makefile.in, scmconfig.h.in: Regenerated.
67 * init.c, readline.c: Don't check if TOTORO is #defined.
69 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
71 * Makefile.am: Adjust for new thread configuration system.
72 (INCLUDES): Include the value of THREAD_CPPFLAGS.
73 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
75 (THREAD_LIBS): Definition deleted; automake will generate such
77 * Makefile.in: Regenerated.
79 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
81 Simplify smob and port marking; set the mark bit in the generic
82 marking code, and make marker routines only responsible for
83 turning up outgoing pointers.
84 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
85 before calling the marking function. Don't call the marking
86 function if it's zero.
87 * markers.c (scm_mark0): Just return #f. This function isn't
88 necessary at all now, but it's harmless to call it. We'll leave
89 it in so other folks' code doesn't croak at link time.
90 (scm_markcdr): Don't call SCM_SETGC8MARK.
91 * async.c (mark_async): Don't call SCM_SETGC8MARK.
92 * dynl.c (mark_dynl_obj): Same.
93 * root.c (mark_root): Same.
94 * srcprop.c (marksrcprops): Same.
95 * unif.c (markra): Same.
96 * variable.c (scm_markvar): Same.
97 * ports.c (scm_markstream): Same.
98 (void_port_ptob): Specify zero for our marking function.
99 * debug.c (debugobjsmob): Same.
100 * dynwind.c (guardsmob): Same.
101 * filesys.c (dir_smob): Same.
102 * fluids.c (fluid_smob): Same.
103 * fports.c (scm_fptob, scm_pipob): Same.
104 * mallocs.c (mallocsmob): Same.
105 * regex-posix.c (regex_t_smob): Same.
106 * smob.c (freecell, flob, bigob): Same.
107 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
108 * throw.c (jbsmob, lazy_catch_funs): Same.
110 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
112 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
113 scm_copy_tree on code in order not to let memoized code to leak
114 out. Thus, scm_copy_tree needs to copy vectors as well since
115 quasiquote can introduce evaluated code also inside vector
118 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
120 * eval.c (scm_copy_tree): Removed ability to copy vectors.
122 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
123 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
126 * unif.c: Say that ivect and uvect are of type signed and unsigned
127 long instead of int in commentary so that it correctly describes
130 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
132 * stime.c: Removed declaration of strptime. (It should be
133 declared by the system headers. If it turns out that some systems
134 don't, we'll handle that then.) (Thanks to Greg Troxel.)
136 * stime.h: Renamed TIMEH --> STIMEH
138 * backtrace.c (scm_display_error, scm_display_backtrace): In order
139 to increase portability, don't use structure assignment.
140 (Thanks to Nicolas Neuss.)
142 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
144 (finalize_fd_sets): Added empty statement after last case label.
145 (Thanks to Nicolas Neuss.)
147 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
150 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
152 * init.c, readline.c: OK, I won't have these readline.x bug
153 reports anymore. We've had them since April. The current reason
154 is a completely unintelligible failure of totoro.red-bean.com to
155 do the test for rl_getc_function in libreadline correctly. This
156 kludge overrides the test if we're on totoro so that the snapshot
157 generation process can work.
159 * readline.c: Define a strdup replacement if not existent on system.
161 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
163 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
164 This change makes scm_make_vector R5RS compatible. We cannot keep
165 the third argument since people want to be able to deduce the form
166 of the C function call only by looking at R5RS. (At the same time
167 we have removed some unnecessary complexity!)
169 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
170 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
171 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
172 argument in call to scm_make_vector.
174 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
176 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
177 This macro is useful in applications.
179 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
181 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
182 (scm_parse_path, scm_search_path): New Scheme level procedures.
184 * load.h (scm_internal_parse_path, scm_parse_path,
185 scm_search_path): Declared.
187 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
189 * filesys.c (dirname, basename): New procedures.
191 * init.c (scm_boot_guile_1): Removed condition around
194 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
195 new data type (guards) for representation of C level guards and
196 data on the wind chain.
197 (scm_internal_dynamic_wind): New function.
199 * dynwind.h: Declare scm_internal_dynamic_wind.
201 * root.h (scm_root_state): Added scm_cur_loadp.
203 * root.c (mark_root): Added comment about cur_loadp.
205 * load.c: #include "dynwind.h";
206 (scm_primitive_load): Use scm_inner_dynamic_wind to update
209 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
211 * ports.c (current-load-port): New procedure.
213 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
215 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
216 not a tty, return #f.
218 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
219 to Julian Satchell and Roland Kaufmann.)
221 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
222 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
224 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
226 * debug.h, debug.c (scm_start_stack): New function. Implements
227 the guts of old scm_m_start_stack.
229 * debug.c (scm_m_start_stack): Use scm_start_stack.
231 * init.c (scm_start_stack, scm_restart_stack): Renamed to
232 start_stack and restart_stack. (These have static scope.)
234 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
236 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
237 readline functions to come in release 2.3. (Thanks to Chet
239 (handle_errors): Use the above functions.
241 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
243 * readline.c: Improvements for readline support: Handle errors
244 better; Implement before-read-hook.
246 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
248 * init.c (scm_boot_guile_1), readline.c: Test for
249 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
250 assure that we have version >= 2.1.)
252 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
254 * readline.c (scm_add_history): Bugfix: Do strdup before giving
255 away the string to add_history.
256 (completion_function): Do completion for readline. (Thanks to
258 (scm_filename_completion_function): New procedure: Filename
260 (current_input_getc): New function. Use this one instead of
261 standard getc from readline.
263 * throw.c, throw.h (scm_handle_by_throw): New function: This
264 handler throws errors to next handler on the dynwind chain.
266 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
268 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
271 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
273 * procprop.c (scm_i_procedure_arity): New function. Returns arity
275 (scm_procedure_properties): Modified to return arity together with
277 (scm_procedure_property): Added the read-only property `arity'.
278 (scm_set_procedure_property_x): It is an error to set the `arity'
281 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
282 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
284 * procprop.h (scm_sym_arity): New symbol.
286 * objects.c (scm_set_object_procedure_x): New procedure: Use this
287 to set the dispatch procedure of an operator or entity object.
289 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
290 Made procedure slots read-only.
292 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
293 scm_tcs_cons_gloc case in zero args switch; Fixed args
294 construction for operators in scm_tcs_cons_gloc case in two args
297 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
299 * fluids.c: Removed use of assert.h (in order to avoid
302 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
304 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
306 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
307 change makes the evaluator safer at the cost of evaluation speed.
308 It handles the case when the user has added a non-immediate
309 improper end of the application form, e.g., `(+ 0 . x)'.
310 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
311 minimize the extra cost as much as possible. The new code is
312 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
313 problem with structs planted directly in the code (e.g. by a
314 macro). This no longer causes segmentation fault. (Thanks to
317 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
318 arg `proc' in order to be able to throw errors; New argument
321 * Removed extra #include "debug.h"
323 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
325 * scmsigs.c: Declare usleep as returning void on some systems.
326 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
329 * coop.c (usleep): Return void on some systems.
331 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
333 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
335 * coop.c: Changed return type of usleep to int.
337 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
338 isn't found in the OS.
340 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
341 isn't enabled. (Thought that I had made this change ages ago...)
343 * iselect.c: Declare bzero if not defined by OS.
345 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
347 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
348 condition. (Thanks to John Tobey.)
350 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
351 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
354 * __scm.h: Start the long-term project of moving to POSIX threads.
355 Phase 1: Classification of all critical sections.
356 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
357 for A sections. (See comments in __scm.h for details.)
359 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
360 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
362 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
364 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
365 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
366 (libpath.h, versiondat.h): Replaced dependency on Makefile with
367 dependencies on $(srcdir)/Makefile.in
368 $(top_builddir)/config.status in order to avoid circularity.
370 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
371 from argc if argc was 0 initially.
373 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
374 in generation of libpath.h.
376 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
378 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
379 libguile from 2 to 3.
381 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
383 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
385 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
387 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
388 scm_set_port_column_x, scm_port_filename,
389 scm_set_port_filename_x): Removed optional arguments. Added
390 proper argument checking.
392 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
393 stack size in machine words.
395 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
396 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
397 to Ole Myren Röhne.)
399 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
401 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
402 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
404 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
407 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
408 procedure apply: Copy argument lists before pushing them unto the
409 environment so that the environment won't get mutated due to
410 manipulation of procedure arguments. This should perhaps be
411 regarded as a temporary solution until someone finds a more
412 efficient one. (Thanks to Maciej Stachowiak.)
414 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
416 * script.c (scm_compile_shell_switches): Use "guile" as default
417 zero arg if argc is NULL.
419 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
421 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
422 is zero. (Thanks to Dirk Herrmann.)
424 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
426 * ports.c (scm_add_to_port_table): First line is now line 0
427 (was 1). (Interface changed according to suggestion by Per
430 * backtrace.c (display_header): Add 1 to line and column numbers
431 when presenting them to the user.
433 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
434 from debug.c --> eval.c
436 * eval.h, eval.c (scm_eval_options_interface): New options
438 (SCM_EVAL_STACK): New option: Size of newly created stacks,
439 i.e. stacks for new threads.
441 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
443 * eval.c (unsafe_setjmp): Removed with #if 0.
445 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
448 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
449 to avoid compiler warnings.
451 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
453 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
455 * throw.c (handler_message): Print message on current error port
456 instead of default error port. (Thanks to Maciej Stachowiak.)
458 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
460 * ports.c (scm_add_to_port_table): allocate in units of
461 struct scm_port_table *, not struct scm_port_table.
462 * posix.c (scm_close_pipe): remove the port from the port table
464 Thanks to Rob Engle for both fixes.
466 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
468 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
469 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
471 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
473 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
475 * backtrace.c (display_error_body, display_backtrace_body),
476 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
477 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
478 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
479 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
482 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
483 don't receive the jmpbuf arg anylonger.
484 (scm_catch): Don't accept a #f tag.
485 (scm_throw): Check that key is a symbol.
486 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
488 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
490 * async.c (async_pending): Removed declaration.
492 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
494 * dynwind.c (scm_wind_chain): New debug function.
496 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
497 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
498 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
499 extra layer of functions around the body and handler of a thread.
500 This extra layer makes sure that the handler is called in the
501 dynamic context of the surround (= empty dynwind list), but under
502 the *dynamic root* of the body. We can not use the dynamic root
503 of the surround since that root belongs to another thread => stack
504 is not handled correctly. It may seem ugly to use this extra
505 layer, but the extra cost in terms of execution time is really
506 negligible compared to the total amount of time required to create
507 a thread, and it would reduce maintainability to duplicate the
508 crucial and complicated steps performed by cwdr.
510 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
511 (SCM_ALLOW_INTS): Added thread switching code before interrupts
512 get re-enabled. The important effect of this is that interrupts
513 are blocked during thread switching so that thread data structures
514 don't risk getting messed up by an unfortunate signal.
515 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
516 seems to do more aggressive optimization which actually move
517 instructions around in these macros in a fatal way. Therefore:
518 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
519 just superstitious...)
520 (SCM_TICK): Maybe do a context switch and take care of asyncs.
521 This macro should be used instead of SCM_ASYNC_TICK since the
522 latter doesn't do context switches any more.
524 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
525 instead of SCM_ASYNC_TICK.
527 * coop.c, iselect.c: Since thread switches are now performed with
528 interrupts masked, we can't use the old mechanism of delivering
529 signals immediately when they arrive. Signals must instead be
530 delivered when the asyncs run *after* the end of the critical
531 section in scm_internal_select. But this also means after context
532 switch so that the signal will be delivered to a different thread.
533 To avoid this, I have changed the protocol of
534 coop_wait_for_runnable_thread and friends so that they are allowed
535 to return the original thread. So, if a signal arrives during
536 scm_internal_select, we won't any longer be forced do a context
537 switch, but can remain in the same thread and deliver the signal
540 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
541 scm_asyncs_pending and made it global.
543 * iselect.c: Small fixes.
545 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
546 coop_condition_variable_init, coop_condition_variable_wait,
547 coop_condition_variable_signal): Changed return type from `void'
548 to `int'. This is to adhere closer to the pthreads interface.
549 This, in turn, is part of an attempt to provide C versions of the
550 mutex and condition variable primitives which can be part of a
551 frontend to COOP or pthreads.
553 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
554 coop_condition_variable_destroy): New functions.
556 * coop-threads.c (scm_wait_condition_variable): Use
557 coop_condition_variable_wait_mutex.
559 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
560 Definitions moved to coop-defs.h.
562 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
563 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
564 scm_cond_destroy): New C interface to mutecis and cond vars.
566 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
568 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
570 * iselect.c: Now several threads can wait on the same file
571 descriptor. The behaviour is compatible with OS select: All
572 threads waiting for the fd return with the same status.
574 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
576 * coop-threads.c, threads.h (scm_spawn_thread): New function.
577 Can spawn a thread from application C code.
579 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
581 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
582 gh_doubles2scm): New functions.
584 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
586 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
587 commented-out version of gh_eval_str()
589 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
591 * socket.c (scm_bind): free soka after use.
593 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
595 * stime.c (tzvar): new variable.
596 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
597 avoid memory leaks when allocating.
599 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
601 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
604 * gc.c, tags.h: Doc fixes.
606 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
608 * eval.c (macro-eval!): Removed. This function was a design bug.
609 It allowed memoized code to leak out to the scheme level. Most
610 things that you could do with `macro-eval!' can be done with
613 1997-12-20 Tim Pierce <twp@skepsis.com>
615 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
616 scm_fgets now depends on ftell(3) to know how many bytes were
619 1997-12-15 Tim Pierce <twp@skepsis.com>
621 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
622 dealing with strings.
624 1997-12-13 Tim Pierce <twp@skepsis.com>
626 Make %read-line more suitable for implementing read-line efficiently.
627 * ioext.c (scm_read_line): Strip the terminating newline from a
628 string, and return a cons of the string and its terminator.
630 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
631 of the string that is read is stored in this memory location.
632 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
633 * genio.c, genio.h (scm_do_read_line): Update caller.
634 * ports.h (scm_ptobfuns): Update typedef.
635 * fports.c (scm_fptob, scm_pipob): Update struct.
637 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
639 * filesys.c (set_element): Return file descriptor.
640 (fill_select_type): Return the highest file descriptor.
641 (scm_select): Tell select about the highest file descriptor. On
642 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
643 Therefore the extra overhead for calculating the maximum fd seems
644 to be more than compensated. Is this correct? In any case,
645 scm_internal_select will be much faster with this info.
646 (scm_select, fill_select_type, set_element): Don't accept any kind
647 of object in the file descriptor list or vector.
649 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
651 * iselect.c (finalize_fd_sets): Bugfix.
653 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
655 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
656 when using scm_internal_select (since we might switch to another
659 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
661 * simpos.c (scm_system): always define: use sysmissing if not
662 available. Check for HAVE_SYSTEM instead of _Windows (does
663 Windows lack system or does it have an unusable one?).
664 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
665 Let the argument be optional: if not supplied, call system(NULL).
667 * ports.c (scm_close_port): relax the type check from OPPORTP to
668 PORTP; closing a closed port is allowed.
670 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
672 * fports.c (scm_fgets): Return if the last char in a chunk is
673 newline. When fgets returns a string whose length is `size-1', it
674 is ambiguous whether a whole line was retrieved, so we must check
675 explicitly whether a line terminator is present.
677 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
679 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
680 before taking the CDR. (Thanks to Harald Meland.)
682 * filesys.c (scm_stat): Slightly optimized.
684 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
686 * ports.c (scm_close_port): Make sure the port is open before
689 * guile-snarf.in: Pass args through to gcc in a way that preserves
690 whitespace boundaries. (Thanks to Greg Badros.)
692 1997-12-02 Tim Pierce <twp@skepsis.com>
694 * stacks.c (scm_frame_procedure): Reverse the logic in the return
695 statement. (Thanks to Doug Evans for pointing this out.)
697 1997-12-01 Tim Pierce <twp@skepsis.com>
699 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
701 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
703 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
704 errno macro expansion of this field name. (errno is a C
705 preprocessor macro on some systems.)
707 1997-11-29 Tim Pierce <twp@skepsis.com>
709 * iselect.c: Doc fix.
711 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
713 * init.c (scm_start_stack): Removed initialization of
714 scm_the_last_stack_var.
716 * backtrace.h: Declare scm_the_last_stack_var.
718 * backtrace.c: Define scm_the_last_stack_var.
720 * root.c (mark_root): Don't mark the_last_stack_var.
722 * root.h (scm_root_state): Removed the_last_stack_var.
724 * throw.c: Added #include "fluids.h"
725 (ss_handler): `the-last-stack' is now a fluid.
727 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
728 --> the_last_stack_fluid.
730 * backtrace.c: Added #include "fluids.h"
731 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
732 (scm_backtrace): `the-last-stack' is now a fluid.
734 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
735 after scm_init_fluids.
737 1997-11-28 Tim Pierce <twp@skepsis.com>
739 * iselect.c: #ifdef USE_THREADS around thread-related includes.
741 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
742 DLSYM_ADDS_USCORE to decide whether to add an underscore.
744 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
746 * iselect.c (coop_next_runnable_thread,
747 coop_wait_for_runnable_thread): Disable interrupts so that no
748 async is executed before a potential error_revive.
749 (scm_internal_select): Disable interrupts during the parts of the
750 code which manipulate the sleep queue and the file descriptors.
752 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
754 * Makefile.am: Added iselect.c and iselect.h.
756 * coop.c (coop_qinit): Initialize fields used by
758 (coop_qget, coop_qget, coop_tmp_queue): Made global.
759 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
760 replacement in iselect.c.
761 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
762 coop_join): If GUILE_ISELECT enabled, use
763 coop_wait_for_runnable_thread instead of
764 coop_next_runnable_thread.
765 (usleep, sleep): New replacements for system functions if
766 GUILE_ISELECT is enabled.
768 * coop-threads.h: Declare coop_wait_for_runnable_thread.
770 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
772 * filesys.c: Added #include "iselect.h". Moved FD-macros to
773 iselect.h. Implement Scheme level `select' using
774 scm_internal_select. (See NEWS.)
776 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
778 * init.c: Call scm_init_iselect.
780 * iselect.h, iselect.c: New files. Implements
781 scm_internal_select. (See NEWS.)
783 1997-11-27 Tim Pierce <twp@skepsis.com>
785 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
786 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
787 and scm_must_free, since ultimately the string returned will be copied
788 by scm_makfrom0str anyway. Also, read any characters that may have
789 been pushed onto the port with scm_ungetc.
790 * ports.c (scm_generic_fgets): Same as for scm_fgets.
791 * ioext.c (scm_read_line): Free string after Guilifying it.
792 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
794 1997-11-26 Anthony Green <green@hoser.cygnus.com>
796 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
798 * gh.h: Safely wrap prototypes for c++ usage.
800 1997-11-25 Mark Galassi <rosalia@cygnus.com>
802 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
803 gh_repl (argc, argv).
805 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
807 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
808 and to invoke scm_shell().
809 (gh_launch_pad): took out the loading of boot-9.scm from here,
810 since it is probably best to let the user control that. In fact,
811 gh_repl() now invokes scm_shell() which does that.
813 1997-11-23 Mark Galassi <rosalia@cygnus.com>
815 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
818 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
820 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
821 yesterday's underscore patch. (Thanks to Marius Vollmer for
824 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
826 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
827 DLSYM_ADDS_USCORE is not defined.
829 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
831 * gh_data.c (gh_uniform_vector_length):
832 (gh_uniform_vector_ref): started implementing the uniform types in
835 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
837 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
838 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
840 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
842 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
843 configure.in was changed).
845 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
847 * Makefile.am (modinclude_HEADERS): Include readline.h here.
848 * Makefile.in: Regenerated.
850 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
852 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
853 OPORT is an `open' port, not an output port.
855 * filesys.c (scm_close, set_element, get_element, scm_chown,
856 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
857 SCM_COERCE_OUTPORT to cope with the printstate/port magic.

859 scm_close_port, scm_port_line, scm_set_port_line_x,
860 scm_port_column, scm_set_port_column_x, scm_port_filename,
861 scm_set_port_filename_x, scm_port_mode,
862 scm_close_all_ports_except, scm_set_current_output_port,
863 scm_set_current_error_port): Likewise
864 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
865 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
867 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
868 * backtrace.c (display_backtrace_body): Likewise
869 * fports (scm_setvbuf): Likewise
870 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
871 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
872 scm_getpeername, scm_send, scm_sendto): Likewise
873 * unif.c (scm_uniform_array_write): Likewise
875 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
877 Minor problems with substring-related tag changes.
878 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
879 exactly what we want to leave in to detect substrings.
880 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
881 * tags.h: Fix diagrams and comments describing the S tag bit;
882 remove vestigial remarks about the D tag bit.
883 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
884 * strings.c: Formatting tweaks.
886 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
887 variable first; then SCHEME_LOAD_PATH, with a warning message.
888 (scm_parse_path): New function.
889 * script.c: Doc fixes.
891 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
893 Readline support, from Daniel Risacher.
894 * readline.c, readline.h: New files.
895 * init.c: #include "readline.h".
896 (scm_boot_guile_1): Call scm_init_readline, if we have it.
897 * Makefile.am (libguile_la_SOURCES): Include readline.c.
898 * Makefile.in: Regenerated.

905 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
907 * gh_data.c (gh_vector_set_x): changed name to make it consistent
908 with the ! -> _x mapping when going from Scheme to C.
910 1997-10-19 Mark Galassi <rosalia@cygnus.com>
920 (gh_assoc): added these gh_ functions implemented as macros.
922 * gh_predicates.c (gh_null_p):
923 (gh_string_equal_p): added these two missing predicates.
925 * gh_list.c (gh_append):
930 (gh_set_cdr_x): added these routines as I go through and try to
931 complete the picture R4RS functions that should be mirrored in the
934 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
936 * tags.h (scm_tc7_substring): Changed the comment and code to
937 conform with the changes below. Folks! We have suddenly two new
938 free tc7 codes!!! Jummy, jummy!
940 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
942 * Makefile.in: Rebuilt.
943 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,

956 * gscm.c (gscm_run_scm): Don't init mbstrings module.
957 * gc.c (scm_gc_mark): Don't handle mbstrings.
958 (scm_gc_sweep): Likewise.
959 * eval.c (SCM_CEVAL): Don't handle mbstrings.
960 * eq.c (scm_equal_p): Use SCM_TYP7S, not SCM_TYP7SD.
961 * tags.h (SCM_TYP7SD): Removed.
962 (SCM_TYP7D): Removed.
963 (scm_tc7_mb_string): Removed.
964 (scm_tc7_mb_substring): Removed.
965 * print.c (scm_iprin1): Handle char printing directly. Don't
967 Don't include "mbstrings.h".
968 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
969 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
971 Don't include "mbstrings.h".
972 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
973 (SCM_SYMBOL_SLOTS): Define as 4.
974 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.

977 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
978 struct.c, threads.c, throw.c, unif.c, variable.c: Use new
979 ("gen"-less) I/O function names.
980 * ports.c (scm_add_to_port_table): Don't set port's
982 * ports.h (scm_port_representation_type): Removed.
983 (scm_string_representation_type): Removed.
984 (struct scm_port_table ): Removed representation field.
985 (SCM_PORT_REPRESENTATION): Removed.
986 (SCM_SET_PORT_REPRESENTATION): Removed.

998 1997-10-12 Mark Galassi <rosalia@cygnus.com>
1000 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
1002 * gh_test_c.c (c_vector_test): some improvements on the vector
1005 * gh.h (gh_vector): this used to exist but do the wrong thing.
1006 Now it (almost) does the right thing, though it takes a list
1007 instead of the individual arguments. I need to see how it could
1009 (gh_list_to_vector): added this function as a macro. Corresponds
1010 to Scheme's (list->vector ...).
1011 (gh_vector_to_list): added this function as a macro. Corresponds
1012 to Scheme's (vector->list ...).
1014 * gh_data.c (gh_vector_ref): renamed from gh_vref to
1015 gh_vector_ref, so that it resembles the Scheme routines more.
1016 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
1017 resembles the Scheme routines more.
1018 (gh_make_vector): this used to be (stupidly) called gh_vector().
1019 This is the right name, since it does the same thing as the Scheme
1020 (make-vector ...) procedure.
1022 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
1024 * ports.h: #include "libguile/print.h"

1034 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
1036 * gh_data.c (gh_bool2scm): new function which replaces
1037 gh_int2scmb(), which is now tagged as obsolete.
1039 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
1041 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
1042 macros should by convention not test for NIMPness.)
1043 (SCM_COERCE_OPORT): Adjust indentation.
1045 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
1046 SCM_NIMP test before SCM_PRINT_STATE_P.
1048 * struct.c, struct.h, gc.c: Renamed:
1049 scm_struct_i_layout --> scm_vtable_index_layout
1050 scm_struct_i_vcell --> scm_vtable_index_vcell
1051 scm_struct_i_vtable --> scm_vtable_index_vtable
1052 scm_struct_i_printer --> scm_vtable_index_printer
1053 scm_struct_i_vtable_offset --> scm_vtable_offset_user
1055 * struct.c (scm_print_struct): Use new printer slot; Default
1056 printing: Also output hex code of vtable so that type identity
1057 will be indicated as well.
1058 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
1059 Removed struct_printer_var; Removed struct-vtable-offset;
1060 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
1061 vtable-offset-user): New constants.
1063 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
1064 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
1065 If this slot contains a procedure, use that to print structures of
1066 the type represented by this vtable.
1068 * print.c (scm_iprin1): Don't print arguments of macro
1069 transformers. (They are always: exp env.); Bugfix: Unmemoize
1070 transformer source with correct environment.
1072 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
1074 Streamlining of call-with-dynamic-root:
1076 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
1077 there is now only one catch.
1078 (cwdr_outer_body): Removed.
1079 (cwdr_handler): New function.
1080 (scm_internal_cwdr): New function to perform the function of cwdr
1081 but take args that are more useful to C code. Also, the handler
1082 is now invoked *outside* of the new dynamic root, like the docs
1083 say. We no longer have to catch absolutely all errors, the caller
1084 is responsible for using a handler that does not throw, if he
1086 (cwdr): Reimplemented in terms of scm_internal_cwdr.
1087 * root.h (scm_internal_cwdr): New prototype.
1089 Even more but risky streamlining:
1091 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
1092 allocation of the jumpbuf of a root continuation. The changes
1093 below are controlled by it. They are now deactivated.
1094 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
1095 the JMPBUF of the scm_rootcont to NULL before returning.
1097 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
1098 when they are non-NULL.
1099 (scm_gc_mark): Likewise, mark only when non-NULL.
1101 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
1102 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
1104 * gc.c (scm_done_malloc): New function.
1105 gc.h (scm_done_malloc): New prototype.
1107 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
1108 (struct scm_print_state) [revealed]: New field.
1109 (scm_print_state_vtable): Make visible to the outside world for
1110 type checking purposes.
1111 (scm_valid_oport_value_p): New prototype.
1113 * print.c (scm_valid_oport_value_p): New function to check whether
1114 a certain value is acceptable as a port argument.
1115 (scm_print_state_vtable): New variable.
1116 (scm_free_print_state): Set `revealed' field to false.
1117 (scm_iprin1): Call user supplied closure printer with
1118 scm_printer_apply. Print in the traditional way when there isn't
1119 one or when it returns #f.
1120 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
1121 Accept a port/print-state pair in addition to just a port.
1122 (scm_prin1): Don't return the print_state to the pool when it has
1124 (scm_printer_apply): Set `revealed' field of print_state to true.
1125 (scm_init_print): Set scm_print_state_vtable.
1126 (print_state_fluid, print_state_fluid_num): Removed.
1128 * throw.h (scm_handle_by_proc_catching_all): New prototype
1129 throw.c (scm_handle_by_proc_catching_all): New function
1131 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
1133 * Makefile.in: Regenerated with automake 1.2c.
1135 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
1137 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
1138 was looping endlessly.
1140 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
1142 * strports.c (scm_eval_string): Don't close the port.
1144 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
1145 former returns a nice normal integer. (Thanks to Daniel
1148 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
1150 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
1151 makefile variable as a build parameter called LIBS. The
1152 build-guile program will use this, for the time being.
1153 * Makefile.in: Regenerated.
1155 Thanks to Shiro Kawai:
1156 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
1157 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
1160 * Makefile.in: Regenerated with automake 1.2a.
1162 * script.c (scm_compile_shell_switches): If we hit the -c or --
1163 arguments, don't set the car of (command-line) to scm_usage_name,
1164 the prettified name of the guile executable; give it the full
1165 path, the way shells usually handle $0.
1167 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1169 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
1170 Scheme-level name `array-map' and renamed `serial-array-map' to
1171 `serial-array-map!'.
1173 * backtrace.c: Introduced exception handlers which now enclose
1174 `display-error' and `display-backtrace' so that error reporting
1175 won't get into infinite loops if an error occurs during displaying
1176 of the error. This can very easily happen with user supplied
1177 print call-back routines.
1179 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1181 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
1182 the names `serial-array-map' and `array-map' should be removed.)
1184 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
1186 * init.c (scm_boot_guile_1): Added scm_init_objects ().
1187 Added #include "objects.h"
1189 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
1190 Add #include "feature.h".
1192 * Makefile.am (libguile_la_SOURCES): Added objects.c.
1193 (modinclude_HEADERS): Added objects.h.
1195 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
1196 This test is needed at many places in the code and should be
1197 abstracted. (Motivated by the need of this test in libguiletk.)
1199 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
1200 (scm_eval_string), load.c (scm_primitive_load,
1201 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
1202 Use SCM_EOF_OBJECT_P.
1204 * eval.c (scm_init_eval): Add feature `delay'.
1206 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1208 * scmhob.h: Removed.
1210 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1212 * list.h (SCM_LISTn): New macros. Make list creation in C code
1213 prettier. The idea comes from STk.
1215 * sequences.h, sequences.c, append.h, append.c: Removed. These
1216 files implemented non-R4RS operations which would encourage
1217 non-portable programming style and less easy-to-read code.
1219 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
1222 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
1223 sequences.h, #include append.h.
1225 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
1228 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
1230 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
1232 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
1234 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1236 * eval.c: Added #include "objects.h"
1238 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
1241 * smob.c (scm_smob_prehistory): Create two objectsmobs with
1242 adjacent smob numbers.
1244 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1246 * procprop.h: Added declaration of scm_i_inner_name.
1248 * gsubr.c: New global symbol scm_i_inner_name.
1250 * debug.c (scm_procedure_name): Try procedure property
1251 `inner-name' if `name' fails.
1253 * print.c (scm_iprin1): Use scm_macro_name.
1255 * eval.c (scm_m_define): Give names to macros as well; Only the
1256 first top-level definition gives a procedure/macro a name.
1257 Otherwise confusing names can turn up in backtraces.
1258 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
1259 `name'; Give names to macros as well.
1261 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
1262 (scm_macro_transformer): Use SCM_CLOSUREP instead of
1265 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1267 * * eval.c (macro?, macro-type, macro-name, macro-transfomer): New
1269 (prinmacro): Removed. The code has been moved/merged into print.c
1270 in order to decrease code redundancy. We want macros to print in
1271 a way equivalent to procedures, and it would be silly to duplicate
1272 the required code. (We don't want to maintain two places.)
1273 (macrosmob): Print field is now a NULL pointer.
1275 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
1276 scm_macro_transformer): New prototypes.
1277 (scm_tc16_macro): Declared.
1279 * * print.c (scm_iprin1): Added code for printing of macros. Macros
1280 are now printed in a way equivalent to procedures.
1282 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
1284 * procs.h (scm_closure_p): Added declaration.
1286 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1288 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
1289 Shouldn't pass "heap" as the subr name.
1291 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
1293 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
1294 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
1295 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
1296 gh_equal_p): Use SCM_NFALSEP, instead of testing against
1297 SCM_BOOL_T. Any non-false value is true.
1299 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1301 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
1302 scm_gensym): Added prototypes.
1304 * symbols.c (scm_gensym): New function. This will speed up
1305 certain types of applications (such as macro systems) which
1306 generate lots of symbols.
1308 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1310 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
1312 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
1314 * unif.c (scm_shap2ra): tighten the checking of the array dimension
1315 specifier, since (2) or (2 . 3) would cause SEGV.
1316 (scm_transpose_array): more argument checking fixes.
1318 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
1320 * Makefile.in: Regenerated.
1322 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
1324 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
1326 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1328 * error.c, error.h (scm_error_callback): Removed (see NEWS).
1330 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
1332 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
1333 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
1336 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
1337 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
1338 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
1339 scm_array_p, scm_array_rank, scm_array_dimensions,
1340 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
1341 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
1342 scm_array_prototype): Added case scm_tc7_wvect.
1344 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
1346 * errno.h: prototype for scm_strerror.
1347 * error.c (scm_strerror): new procedure.
1349 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1351 * list.c (scm_list_append_x): Allow non-pair as last argument.
1352 This is consistent with the R4RS append and is probably the
1353 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
1355 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1357 * stime.h: prototype for scm_times.
1358 * stime.c (scm_times): new procedure.
1359 * ioext.c (scm_fseek): if the first argument is a file descriptor
1361 (scm_ftell): if the first argument is a file descriptor call lseek
1363 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
1364 * filesys.c (scm_chmod): if the first argument is a file descriptor,
1366 (scm_chown): if the first argument is a port or file descriptor,
1368 (scm_truncate_file): new procedure.
1369 Add DEFER/ALLOW INTS to a few other procedures.
1370 (scm_fsync): new procedure.
1371 (scm_open_fdes): new procedure.
1372 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
1374 (scm_fcntl): the first argument can now be a file descriptor. The
1375 third argument is now optional.
1377 * posix.c (scm_execl, scm_execlp): make the filename argument
1378 compulsory, since omitting it causes SEGV.
1379 (scm_sync): return unspecified instead of #f.
1380 (scm_execle): new procedure.
1381 (environ_list_to_c): new procedure.
1382 (scm_environ): use environ_list_to_c. disable interrupts.
1383 (scm_convert_exec_args): take pos and subr arguments and
1384 improve error checking.
1386 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1388 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
1389 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
1390 argument to SCM_ASSERT. Furthermore, the name of the function
1391 should be passed as first argument when signalling
1392 SCM_WNA. (Thanks to Thomas Morgan)
1394 * gsubr.c (scm_gsubr_apply): From Radey Shouman
1395 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
1396 dispatches on the number of actual args has a default case
1397 reporting an internal error. This is a vestige from a version
1398 that mallocated a SCM vector to hold the arguments. In the
1399 current version this check is too late: if it ever happens we will
1400 have already overstepped the bounds of the array.
1402 Also, the patch [...] adds a check for too many actual arguments."
1404 mdj: Removed check for "internal programming error".
1406 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1408 * gh_io.c (gh_write): New function.
1410 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
1411 throw.c (scm_internal_stack_catch): New sibling to the other catch
1412 functions. Code moved from gh_eval.c.
1413 throw.h: Added header.
1414 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
1415 scm_internal_stack_catch.
1417 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
1419 * ioext.h: fix up prototypes.
1420 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
1421 Scheme name is now dup->fdes.
1422 (scm_dup_to_fdes): make the second argument optional and
1423 fold in the functionality of scm_primitive_dup.
1424 (scm_primitive_dup): deleted.
1426 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1428 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
1429 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
1430 ultrix are defined. Use setvbuf instead of setbuf.
1431 (scm_setvbuf): new procedure.
1432 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
1433 (scm_setfileno): moved from ioext.c.
1434 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
1435 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
1437 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1439 * fluids.c (scm_fluid_p): New function.
1440 * fluids.h (scm_fluid_p): New prototype.

1444 * print.c (scm_iprin1): Enter printed structures into the print
1445 state as nested data while they are printed.
1446 (print_state_fluid, print_state_fluid_num): New variables.
1447 (scm_init_print): Initialize them.
1448 (scm_iprin): If print_state_fluid carries a print_state, use that
1449 instead of creating a new one.
1450 (scm_printer_apply, apply_stub, struct apply_data): New
1451 definitions to help with calling printer functions written in
1453 * print.h (scm_printer_apply): New prototype.
1455 * struct.c (scm_print_struct): Use scm_printer_apply to call the
1456 user defined struct printer.
1458 * dynwind.c (scm_dowinds): Handle fluids on the wind list.

1464 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
1466 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
1467 SCM_ASSERT: arg comes before pos.
1469 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1471 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
1472 to a list of length zero correctly.
1474 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1476 Supply an `fgets' method for port objects to do fast line i/o.

1488 Mon Jul 21 04:03:42 1997 Gary Houston <ghouston@actrix.gen.nz>
1490 * ioext.h: removed scm_duplicate_port prototype.
1492 * ioext.c (scm_primitive_dup2): return the new file descriptor
1493 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
1495 (scm_fdopen): bug fix: don't try to make port unbuffered until its
1496 stream has been set.
1497 (scm_duplicate_port): deleted, there's now an implementation in
1499 (scm_primitive_dup2): do nothing if newfd == oldfd.
1501 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
1503 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
1506 * ioext.h: new prototypes.
1507 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
1509 * fluids.c (next_fluid_num): don't do
1510 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
1512 * ports.h: prototypes too.
1513 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
1515 * fports.h: prototype too.
1516 * fports.c (scm_evict_ports): moved from ioext.c.
1518 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
1520 * ports.c (scm_close_port): return a boolean instead of unspecified.
1521 throw an error if an error other than EBADF occurs.
1523 * filesys.h: scm_close prototype.
1524 * filesys.c (scm_close): new procedure, can close file descriptors
1525 and ports (scsh compatible).
1527 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
1530 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
1532 * fluids.c, fluid.h: New files.
1533 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
1534 (modinclude_HEADERS): Added "fluids.h"
1536 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to
1537 scm_init_fluids to initialize the fluid machine.
1538 (scm_start_stack): Initialize the fluids of the first root with
1539 scm_make_initial_fluids.
1541 * root.h: Added "fluids" member to scm_root_state.
1542 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
1543 (scm_make_root): Call scm_copy_fluids to make fluid bindings
1544 unique for the new root when it has a parent.
1546 * smob.h: Include "libguile/print.h" to make scm_print_state
1549 * dynl.c (free_dynl_obj): New function to free the dynamic object
1550 data. (dynl_smob): Use it.
1551 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
1552 the dynamic object data below the linking of the object to avoid
1553 memory leak when the linking code throws an error. Now the code
1554 leaks a whole dynamically linked library when must_malloc throws,
1555 but that should be much less likely.
1557 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
1559 Changes to compile under gnu-win32, from Marcus Daniels:
1560 * stime.c (tzset): If tzset isn't provided, make it a NOP.
1561 (scm_localtime): Change SCM_EOF to SCM_EOL.
1562 (scm_mktime): Likewise.
1563 * socket.c: Don't include sys/un.h unless autoconf tells
1564 us Unix domain sockets are available.
1565 (scm_fill_sockaddr): Ignore Unix domain code.
1566 (scm_addr_vector): Likewise.
1567 (scm_init_addr_buffer): Likewise.
1568 (scm_socketpair): Don't include unless socketpair was
1569 found during autoconf.
1570 * simpos.c (SYSTNAME): Treat cygwin like Unix.
1571 * scmsigs.c (scm_pause): Don't include unless pause was found
1573 * posix.c (scm_getgroups): Don't include unless support function
1574 was found during autoconf (in this case, getgroups).
1575 (scm_setpwent): For setpwent.
1576 (scm_setegid): For setegid.
1577 * net_db.c (scm_inet_netof): Don't include unless support
1578 function was found during autoconf (in this case, inet_netof).
1579 (scm_lnaof): For inet_lnaof.
1580 (scm_inet_makeaddr): For inet_makeaddr.
1581 (scm_getnet): For getnetent, getnetbyname, getnetbyaddr.

1586 (scm_setproto): For setprotoent, endprotoent.
1587 (scm_setserv): For setservent, endservent.
1588 * scmconfig.h.in: Regenerated.
1590 Thu Jul 10 00:22:24 1997 Jim Blandy <jimb@floss.red-bean.com>
1592 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
1593 scm_misc_error, not SCM_EOF.
1595 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
1596 arguments for formatting the error message, not SCM_BOOL_F. I
1597 think this is left over from the (eq? '() #f) days.
1599 * read.c (recsexpr): Give this a dummy definition if
1600 DEBUG_EXTENSIONS isn't #defined.
1602 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
1604 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
1607 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>
1609 * root.c (cwdr_outer_body): Bugfix: Pass `c' instead of `&c' to
1612 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
1614 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
1615 alloca.lo will be included in @LIBLOBJS@. Something better than
1616 this should be possible.
1617 * Makefile.in: Regenerated.
1619 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
1621 * simpos.h: prototype for scm_primitive_exit.
1622 * simpos.c (scm_primitive_exit): new procedure, terminates the
1623 process without unwinding the stack.
1625 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
1627 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
1628 argument and logior its components together, so the user doesn't
1629 have to do this explicitly. Also, if regexp/basic is supplied, then
1630 turn off REG_EXTENDED.
1631 (scm_init_regex_posix): New regexp/basic symbol.
1632 (REG_BASIC): #define this if it is not already present.
1634 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1636 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
1637 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
1638 (CLEANFILES): New target, clean versiondat.h, libpath.h.
1639 (DISTCLEANFILES): New target, clean *.x.
1640 * Makefile.in: Regenerated.
1642 Tue Jun 24 00:29:07 1997 Jim Blandy <jimb@floss.red-bean.com>
1644 * script.c (scm_compile_shell_switches): Add 1997 to copyright
1645 years in usage message.
1647 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
1648 * Makefile.in: Regenerated.
1650 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
1651 flag; I don't think we support it.
1652 (scm_make_regexp): Make sure the user doesn't pass the
1655 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
1657 (scm_init_regex_posix): Define constants for the REG_mumble flags;
1658 name them according to the SCSH convention: regexp/mumble.
1660 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
1662 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
1664 * Makefile.am (libpath.h): Include the values of all the standard
1665 Makefile directory variables. Print a message, but don't print
1667 (versiondat.h): Print a message, but don't print all the commands.
1668 * load.c: #include "alist.h".
1669 (init_build_info): New function.
1670 (scm_init_load): Call it.
1671 * Makefile.in: Regenerated.
1673 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
1675 * root.c: Establish a reliable catch-all handler for the new root.
1676 After all the Scheme handler function might signal an error too,
1677 and we don't want to lose that.
1678 (cwdr_inner_body): Renamed from cwdr_body.
1679 (cwdr_outer_body): New function, to establish the user's handler,
1680 and pass control to cwdr_inner_body.
1681 (cwdr): Establish the reliable catch-all handler here, and pass
1682 control to cwdr_outer_body.
1683 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
1684 the user's handler through to cwdr_outer_body.
1685 * throw.c (scm_handle_by_message): Move guts into....
1686 (handler_message): New static function.
1687 (scm_handle_by_message_noexit): New function.
1688 * throw.h (scm_handle_by_message_noexit): New prototype.
1690 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
1691 across this. Only works on GCC. Otherwise, we hope for the best.
1692 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
1693 the feeling that real thread systems will not need this...
1695 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
1697 Try to detect when people are using one version of libguile and a
1698 different version of ice-9. People have been skewing things and
1699 sending in bug reports.
1700 * Makefile.am (versiondat.h): New file to generate.
1701 * version.c: #include "versiondat.h", to get version info.
1702 (scm_libguile_config_stamp): New function.
1703 * script.c: #include "version.h".
1704 (scm_compile_switches): Call scm_version to get version number.
1705 * scmconfig.h.in, Makefile.in: Regenerated.
1706 * Makefile.in: Regenerated.
1708 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
1709 primitive definitions under their Scheme names.
1711 * Makefile.am (libguile_la_LDFLAGS): Update library version to
1712 1:2. Helps avoid confusion between installed and uninstalled libs.
1714 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
1717 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
1718 backslash from definition; this should be used like: GDB_INTERFACE;
1720 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
1722 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
1723 new port unbuffered until its stream has been set.
1725 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
1727 * ports.h: new prototype.
1728 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
1730 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
1732 Make things compile neatly under Sun's C compiler.
1733 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
1734 * extchrs.c (xmbtowc): Make the second arg a normal char, not
1735 unsigned, because that's what the ANSI function takes.
1736 * extchrs.h (xmbtowc): Corresponding change to prototype.
1737 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
1739 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
1740 argument plain char *.
1741 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
1743 * tag.c (scm_tag): Remove unreachable statement.
1744 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
1745 top of the word, it should be unsigned.
1747 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
1748 is defined, to avoid warnings; it's only used in the
1749 conflict-checking code. Which might go away anyway.
1750 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
1751 conditionals; put the label definition in an #if too, to stifle
1754 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
1755 ChangeLog-threads in the distribution.
1756 * Makefile.in: Regenerated.
1758 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1760 * guile-snarf.in: Changed regexp to support CPPs that insert
1761 whitespace between lexical tokens (which munges the `%%%' snarf
1764 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
1766 * load.c (scm_init_load_path): Append $(datadir)/guile to
1767 %load-path, so modules do not have to be installed in Guile's
1768 current version directory.
1770 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
1772 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
1773 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
1774 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
1775 call the sysdep functions with deferred ints.
1776 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
1777 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
1778 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
1781 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
1784 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
1786 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
1788 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
1790 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
1793 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
1795 * eval.c (scm_lookupcar1): New procedure to cope with a race
1796 condition during lookup (when using threads).
1797 (scm_lookupcar): Implement in terms of scm_lookupcar1.
1798 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
1801 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
1803 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
1804 supplied. (Change from Tim Pierce.)
1806 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
1808 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
1809 23:47:01 1997" changelog: Slots are now initialized with `#f' by
1810 default and not `()'. `#f' is the canonical non-value in Scheme,
1813 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
1815 * struct.c (struct_printer): New variable that holds a handle on
1816 the Scheme variable *struct-printer*. This variable can be set by
1817 Scheme code to override the printing of structures.
1818 (scm_print_struct): If struct_printer is set, call it. If it is
1819 not set, or returns #f, print the structure in the old fashion.
1820 Include "eval.h" for scm_apply.
1822 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
1824 * struct.c (scm_struct_ref, scm_struct_set_x): Use
1825 scm_struct_i_n_words to get the number of fields, not
1826 -scm_struct_n_extra_words.
1828 On the route to fancier struct printing:
1829 * struct.c (scm_print_struct): New function to print a structure.
1830 Include "genio.h" to support it. This function doesn't do
1831 anything interesting right now, but I think it should be here
1833 * struct.h: Include "print.h" and add prototype for
1835 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
1836 print structures ourself.
1838 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
1840 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
1841 before applying the handler in case it doesn't return.
1843 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
1845 * scmsigs.h, async.h: updated.
1847 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
1850 * posix.c (scm_uname): interpret only negative values as an error.
1851 Solaris normally returns a positive value.
1853 * script.c (scm_compile_shell_switches): if we are not going into
1854 an interactive repl, set scm_mask_ints to zero so that asyncs can
1857 * simpos.c (scm_system): don't ignore/unignore signals around
1860 * posix.c (scm_open_pipe): don't ignore/unignore signals around
1863 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
1864 done in boot-9.scm instead.
1866 * scmsigs.c, async.c: Major rewriting of signal handling code.
1867 (scm_sigaction): new procedure.
1868 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
1870 (scm_raise): return unspecified, throw error on failure.
1872 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1874 * regex-posix.c (scm_init_regex_posix): Register the "regex"
1875 feature, to help boot-9.scm decide whether to import the regex
1878 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
1880 * eval.c: Include scmconfig.h at the beginning of the file so that
1881 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
1884 * regex-posix.c: #include "_scm.h" before conditionally #including
1885 <regex.h>; the former defines HAVE_REGCOMP.
1887 * regex-posix.c: #include <regex.h> conditionally, so the file is
1888 CPP'able (for dependency scanning) even on systems that don't have
1891 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
1893 Add new R4RS-compliant syntax for keywords.
1894 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
1895 regardless of the setting of the `keywords' read option.
1896 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
1897 can be re-read no matter what the setting of the `keywords' read
1900 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
1902 Add support for POSIX regular expressions.
1904 * regex-posix.c, regex-posix.h: New files. (Some code
1905 is taken liberally from rx/rgx.c in the old Guile dist.)
1907 * init.c: Include regex-posix.h.
1908 (scm_boot_guile_1): Call scm_init_regex_posix.
1910 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
1911 Add regex-posix.[ch] sources.
1912 * Makefile.in: Regenerated.
1914 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
1915 to do this automatically? It didn't for me, bleh.)
1917 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
1919 * fports.c (print_pipe_port): New function.
1920 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
1921 latter doesn't even take the right arguments.
1923 * Makefile.am: Increment shared lib revision number. I think
1924 sometimes the uninstalled Guile finds the installed shared lib;
1925 Gord says doing this might help. As things turned out, I can't
1926 say whether it does.
1927 * Makefile.in: Regenerated.
1929 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
1930 passing it as the closure argument to scm_boot_guile. (Bill
1933 * ports.c (print_void_port, putc_void_port, puts_void_port,
1934 write_void_port, flush_void_port, getc_void_port, close_void_port,
1935 noop0): Use ANSI prototypes instead of K&R declarations, so the
1936 initialization of void_port_ptob gets aggressively type-checked.
1937 Fix arguments of print_void_port and write_void_port. (Bill

1974 here; apparently it's not quite right to have const in a prototype
1975 and then use a K&R declaration. I wonder if stuff like this will
1976 go away if we compile with -Wrequire-prototypes, or whatever that
1977 is... (Bernard URBAN)
1979 * scmhob.h: New text from Bernard URBAN.
1981 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
1983 * script.c: Don't #define const on hpux. Configure takes care of
1984 this. (Thanks to Larry Schwimmer.)
1986 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
1987 decide whether to #include <unistd.h>, instead of listing a bunch
1988 of systems. Don't #include stdio twice. Removed dyked-out
1989 definition of scm_find_impl_file.
1991 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
1993 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
1994 library version info to 1:0.
1995 * Makefile.in: Regenerated.
1997 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,
1998 gdb_interface.h, gdbint.c, gdbint.h, gh_data.c, gh_init.c,

2000 init.c, net_db.c, options.c, options.h, ports.c, print.c, read.c,
2001 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
2002 throw.c: Update copyright years; these files have been worked on
2003 significantly in 1997, but only had copyright years for 1996.
2004 Also, change name of copyright holder on some from Mikael
2005 Djurfeldt to Free Software Foundation; he has signed papers
2006 assigning the changes to the FSF.
2008 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
2009 reason not to give the user the option.
2011 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2012 Return #f on end-of-file when scanning table (i.e. when called
2013 with no arguments). Try to catch errors, when we can.
2014 * posix.c (scm_getgrgid, scm_getpwuid): Same.
2016 * script.h (scm_shell_usage, scm_compile_shell_switches): New
2017 external declarations. These are useful.
2019 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
2021 * posix.c: don't include <sys/select.h> or define macros for
2022 select, since they were not used in this file.
2024 * filesys.c (scm_select): make the fifth parameter microseconds,
2025 not milliseconds. let the fourth parameter be either a real value
2026 or an integer or #f. The first, second and third arguments can
2027 now be vectors: the type of the corresponding return set will be
2029 (set_element, get_element): new static procedures.
2031 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
2033 * strports.c (scm_eval_string): New function.

2040 * fports.c (local_pclose): New function.
2041 (scm_pipob): Use it in the initializer here.
2044 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
2045 Use a meaningful error message when signalling an error. For
2046 this, scm_gethost must check h_errno rather than errno.
2048 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
2050 * Makefile.in: Regenerated, using automake-1.1p.
2052 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
2054 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
2055 not SCM_UNSPECIFIED.
2057 * script.c (scm_compile_shell_switches): don't append (quit) if
2059 (scm_shell): call scm_exit_status and exit on the result of the
2062 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
2064 Ensure that shared substrings are handled properly when passed to
2065 a system call or other foreign function. Many thanks to Tim
2067 * symbols.h (SCM_COERCE_SUBSTR): new macro.
2068 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
2069 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
2070 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
2071 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
2072 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
2073 (scm_display_error_message): use RO macros when strings may be RO.
2074 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
2075 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
2076 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
2077 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
2078 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
2079 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
2080 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
2081 scm_strftime), vports.c (scm_make_soft_port): use
2082 SCM_COERCE_SUBSTR to make sure shared substrings are

2087 * error.c (scm_error): Add newline to error message.
2089 * init.c (scm_init_standard_ports): Doc fix.
2091 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
2093 * dynl-shl.c: Completely replaced with new code from Bernard
2096 * script.c (scm_ice_9_already_loaded): New variable.
2097 (scm_compile_shell_switches): Use it.
2099 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
2101 * filesys.c (scm_input_waiting_p): add missing third argument to
2104 * stime.c (scm_localtime): copy the result of localtime before
2105 calling gmtime in case they share a buffer.
2106 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE

2111 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
2113 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
2115 * Makefile.am (check-local): New target, which causes 'make check'
2116 to run gh_test_c and gh_test_repl, with some trivial input.
2117 * Makefile.in: Rgnrtd.
2119 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
2121 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
2124 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
2126 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
2127 sure how this was supposed to work.
2128 (scm_async_click): don't send SCM_TICK_SIGNAL.
2129 (scm_init_async): don't initialize %tick-thunk.
2131 * the following change doesn't affect the Scheme interface:
2132 gc-thunk is called at the end of garbage collection. however it's
2133 no longer implemented by pretending it's a signal.
2135 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
2136 system async corresponding to scm_gc_thunk.
2137 * async.h: declare scm_gc_async.
2138 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
2139 gc-thunk directly, instead of going through a signal handler.
2140 (scm_gc_async): new variable, points to the GC system-async.
2141 (scm_init_async): save the GC async as scm_gc_async instead
2142 of using system_signal_asyncs.
2143 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
2145 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
2147 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
2148 Don't screw up if we're interrupted.
2149 * Makefile.in: Regeneradet.
2151 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
2153 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
2155 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
2156 we're not using AM_INIT_GUILE_MODULE any more.
2157 * Makefile.in: Reneregated.
2159 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
2161 Functions for finding variable bindings, grace à Tim Pierce.
2162 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
2163 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
2165 Get 'make dist' to work again.
2166 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
2167 * Makefile.in: Regenerated, like a surry without a fringe on top.
2169 Changes for reduced Guile distribution: one configure script,
2171 * configure.in, configure: Removed.
2172 * acconfig.h, acinclude.m4: Moved to parent directory, where the
2173 real configure script lives.
2174 * Makefile.in, scmconfig.h.in: Regenerated.
2176 * init.c: #include "script.h", to get prototype for script.c's
2179 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
2181 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
2182 scm_must_malloc, not raw malloc.
2184 * script.c (scm_compile_shell_switches): Dyke out debugging output
2187 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2189 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
2191 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
2192 system has them. Hope this is safe. Previously
2193 sys/timeb.h was included if HAVE_FTIME was defined or if
2194 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
2195 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
2197 * ioext.c (scm_setfileno): add missing third argument to
2198 scm_misc_error call.
2200 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
2202 * eq.c (scm_equal_p): Correctly compare strings of different
2203 varieties. (Thanks to Tim Pierce.)
2205 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
2207 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
2208 #! block comment must occur on a line all by itself.
2210 Move most of the guts of shell command processing into libguile,
2211 so guile.c can be very small (and eventuallly auto-generated. (I
2212 mean, generated mechanically, not self-generated. Hmm.))
2213 * guile.c, script.c, script.h: New source files.
2214 * init.c (scm_boot_guile_1): Call scm_init_script.
2215 * libguile.h: #include "script.h".
2216 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
2217 targets, for new executable.
2218 (libguile_la_SOURCES): Mention script.c.
2219 (modinclude_HEADERS): Add script.h.
2220 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
2221 not dynamic linking is enabled. This is because we're generating
2222 executables now. Move CY_AC_WITH_THREADS call after those, so the
2223 values of cy_cv_threads_libs captures the libs chosen above.
2224 * Makefile.in, configure, aclocal.m4: Regenerated.
2226 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
2227 We don't maintain this interface any more, and it just confuses
2230 * alloca.c: #include <scmconfig.h>, not <config.h>.
2231 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
2232 it'll get included in disties.
2234 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
2236 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
2237 be distributed, because they confuse people.
2238 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
2240 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
2242 * configure.in: check for presence of gethostent (not present on
2243 OpenBSD by default).
2244 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
2245 * configure, scmconfig.h.in: Regenerated.
2247 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
2249 * backtrace.c (scm_backtrace): Split message string across
2250 newlines properly. GCC is more tolerant of this than other
2253 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
2255 Merge threads directory into libguile.
2256 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
2257 threads.h: New source files.
2258 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
2259 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
2261 (modinclude_HEADERS): Add threads.h, coop-defs.h.
2262 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2263 coop-threads.c.cygnus, coop-threads.h.cygnus.
2264 * configure.in: If we're using threads, include threads.o in
2266 * _scm.h, libguile.h: threads.h lives in this directory now.
2267 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
2268 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
2269 currently used, but brought along for information's sake.
2270 * ChangeLog-threads: log from old 'threads' directory.
2271 * Makefile.in, configure: Rebuilt.
2273 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
2275 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
2278 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
2280 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
2282 Merge GH interface library into libguile.
2283 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
2284 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
2285 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
2286 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
2288 (EXTRA_libguile_la_SOURCES): ... here.
2289 (pkginclude_HEADERS): Add variable, to get gh.h installed.
2290 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
2291 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
2292 New variables, describing how to build the gh test programs.
2293 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
2294 build the test programs, and we probably should have been linking
2295 libguile.la against them all along, to support AIX shared libs.
2296 Add cflags for threads to CFLAGS; add libs for threads to new
2297 variable THREAD_LIBS, used in Makefile.am.
2298 * ChangeLog-gh: log from old `gh' subdirectory.
2299 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
2301 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
2303 * acconfig.h: Undo change of Apr 9; including the definition of
2304 PACKAGE in the guile headers conflicts with applications' own
2306 * scmconfig.h.in: Regenerated.

2315 when PROC is receiving no arguments.
2317 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
2319 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
2320 have S_IFSOCK. This is the case under Ultrix.
2322 * posix.c (scm_status_exit_val, scm_status_exit_val,
2323 scm_status_term_sig, scm_status_stop_sig): Modified to work with
2324 Ultrix versions of WIFSTOPPED, etc., which assume that their
2325 arguments are lvalues (hmm).
2327 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
2329 * eval.c: Doc fixes.
2331 * throw.c: Doc fixes; rearranged.
2333 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.

2337 * acconfig.h: Added entry for PACKAGE.
2338 * scmconfig.h.in: Regenerated.

2341 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
2342 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
2344 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
2346 * Makefile.in: Rebuild.
2348 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2350 * stime.c (scm_mktime): take an optional zone argument.
2351 (scm_localtime): check putenv return value.
2352 (scm_strftime, scm_strptime): moved from posix.c. move #include
2354 stime.h, posix.h: update prototypes.
2355 (bdtime2c, setzone, restorezone): new static procedures.
2356 (scm_mktime, scm_strftime): use them.
2357 (scm_strftime): don't call mktime before strftime. Use
2358 filltime for return value.
2359 (filltime): convert NULL zname to #f.
2360 (scm_strptime): return a count of characters consumed, not
2361 the remaining string.
2363 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2365 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.

2372 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2374 * stime.c (scm_init_stime): don't define ticks/sec.
2375 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
2376 return value problem and is still portable.)
2378 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
2380 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
2381 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
2382 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
2383 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
2384 cpp_err_symbols.c): Corresponding changes.
2385 * Makefile.in: Regenerated.
2387 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>

2390 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
2391 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
2392 * putenv.c: new file, from sh-utils 1.12.
2394 * posix.c (scm_environ): use malloc in place of scm_must_malloc
2395 since allocation isn't for Scheme objects.
2396 (scm_putenv): copy strings before placing in the environment.
2398 * stime.c (scm_current_time): throw an error if time returns -1,
2399 instead of returning #f.
2400 (scm_get_internal_real_time, scm_get_internal_real_time): use
2401 scm_long2num for return value instead of SCM_MAKINUM.
2403 * stime.h: prototypes updated.
2405 * stime.c (scm_time_in_msec): apparently unused, deleted.
2407 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
2409 * configure.in: check for gettimeofday.
2411 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
2412 which may be more usefully portable than a gettimeofday interface.
2414 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
2416 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
2418 * Makefile.in: Regenerated.
2420 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2422 * stime.c (filltime): recovered static procedure.
2423 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
2426 * posix.h: add prototype for scm_close_pipe, remove prototypes for
2427 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
2429 * posix.c (scm_mknod): split the mode argument into type and perms
2430 arguments, like the extra fields returned by stat.
2432 * fports.c (scm_pipob): set the close, free and print procedures.
2433 (scm_close_pipe): new procedure.
2435 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
2436 define them in boot-9.scm
2438 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2440 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
2441 wan't defined. Don't include fd.h.
2443 * Previously fd.h was regenerated whenever configure was run,
2444 forcing a couple of files to be recompiled.
2446 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
2447 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
2448 Check for _fileno as well as _file.
2450 * ioext.c: don't fd.h.
2451 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
2454 * Change the stratigy for getting information about errno
2455 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
2456 generating lists of symbols during the build process, which will
2457 not always work, include comprehensive lists in the distribution.
2458 To help keep the lists up to date, the "check_signals" and
2459 "check_errnos" make targets can be used.
2461 * configure.in: don't check for a command to extract errno codes.
2462 * Makefile.am: update file lists, remove errnos.list and errnos.c
2463 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
2464 check_errnos targets.
2465 (CLEANFILES): remove errnos.c and errnos.list, add
2466 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
2467 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
2468 * errnos.default: deleted.
2469 * cpp_signal.c: new file.
2470 * cpp_errno.c: renamed from errnos_get.c.
2471 * cpp_err_symbols, cpp_sig_symbols: new files.
2472 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
2473 * error.c (scm_init_error): #include cpp_err_symbols instead of
2475 * posix.c (scm_init_posix): don't intern signal symbols. #include
2478 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
2480 * strop.c (scm_i_index): allow the lower bound to be equal to the
2481 length of the string, so a null string doesn't always give an error.
2483 * posix.h: new prototypes.
2484 * posix.c (scm_status_exit_val, scm_status_term_sig,
2485 scm_status_stop_sig): new functions, as in scsh. They break down
2486 process status values as returned by waitpid.
2488 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
2490 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
2491 configure doesn't know about it.
2493 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2495 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
2497 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
2498 which defines C variables with global linkage.
2500 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2502 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
2505 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
2507 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
2508 has time to check why this doesn't work well with continuations.
2510 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
2512 * Fix shell syntax error; some shells won't tolerate
2513 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
2515 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
2517 * posix.c (scm_uname): throw an error if uname fails instead
2520 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
2522 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
2525 * async.c (scm_ints_disabled): definition moved from error.c.
2527 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2529 * acconfig.h: Removed PACKAGE.
2531 * scmconfig.h.in: Regenerated.
2533 * snarf.h: g++ says it's non-portable not to specify the first
2534 argument in a varargs declaration. I introduced the first
2535 argument by using preprocessor conditionals.
2537 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
2539 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
2540 (scm_freopen): use RO string macros for filename and modes.
2541 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
2543 * posix.c (scm_getgrgid): simplify conversion of name to C string.
2544 (scm_mknod): use RO string macros for path.
2546 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
2547 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
2549 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
2550 use SCM_ROSTRINGP and SCM_ROCHARS.
2552 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2554 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
2557 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
2558 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
2559 support for byte vectors.
2561 * print.c (scm_iprin1): Limit number of vector elements printed
2562 according to pstate->length.
2564 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2566 * backtrace.c (scm_display_error_message): don't segv if message
2569 * error.h: prototype for scm_error_scm.
2571 * error.c (scm_error_scm): new procedure, reimplements scm-error
2572 in C and uses scm_error.
2574 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2576 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
2577 pointer to the Scheme variable read-hash-procedures and intern it
2578 in scm_init_read. Modify scm_read_hash_extend and
2579 scm_get_hash_procedure to use the pointer.
2581 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
2583 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
2584 (SCM_KEYWORD_STYLE): defined.
2586 * read.c (scm_read_opts): add a keywords option. This isn't a
2587 boolean option, in case someone wants to add support for DSSSL
2589 Setup scm_keyword_prefix symbol.
2590 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
2592 I've left keyword support disabled by default, since it doesn't
2593 seem to break the module system and it gives R4RS standard behaviour.
2594 It can be reactivated with (read-set! keywords 'prefix).
2596 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2598 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
2599 before constructing arbiter.
2601 * eval.c (scm_m_define): Bugfix: Check that the object is a
2602 closure before setting the procedure property!
2604 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
2606 * ports.c: Removed `ungetc-char-ready?'.
2608 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
2610 * read.c (scm_init_read): intitialise scm_read_hash_procedures
2611 (idea from Mikael: make it a pair so scm_permanent object only
2613 (scm_read_hash_extend): don't call scm_permanent_object.
2614 (ideas from Mikael): if chr is already in the list, replace its
2615 procedure instead of appending it again. If proc is #f, remove
2617 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
2619 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
2621 * gdbint.c (gdb_read): update scm_lreadr usage.
2623 * load.h: update prototypes.
2625 * load.c (scm_primitive_load, scm_read_and_eval_x,
2626 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
2628 * read.h: add prototype for scm_read_hash_extend. Change args for
2631 * read.c (scm_read_hash_procedures): new variable.
2632 (scm_read_hash_extend): new procedure.
2633 (scm_get_hash_procedure): new procedure.
2634 (scm_lreadr): use scm_get_hash_procedure instead of an argument
2635 for extended # processing.
2636 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
2637 scm_read_token): remove case_i, sharp arguments. Change callers.
2639 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
2641 * read.h (SCM_N_READ_OPTIONS): increase to 3.
2642 (SCM_CASE_INSENSITIVE_P): define.
2644 * read.c: add case-insensitive option to scm_read_opts.
2645 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
2646 to determine whether to convert symbol case.
2647 (default_case_i): definition removed.
2648 * read.c (scm_read_token): if case_i, downcase ic before doing
2651 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2653 * configure.in: Added configuration option `guile-debug'.
2654 Configure with --enable-guile-debug if you want a bunch of extra
2655 functions used for debugging when developing Guile.
2657 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
2659 * procs.c (make-cclo): New undocumented debugging procedure: Make
2660 compiled closure with internal procedure PROC and length LENGTH.
2661 Only compiled if GUILE_DEBUG is defined.
2663 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
2665 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
2667 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
2669 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
2670 with 3 or more args internally to the evaluator.
2672 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2674 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
2675 with 3 or more args internally to the evaluator. This is mainly
2676 because we don't want to pass entry and exit points of the
2677 debug support twice, but it also seems to increase the speed of
2678 the evaluator for such calls (e. g. (+ 1 2 3)).
2680 * backtrace.c (scm_display_application): New procedure:
2681 display-application; Set fancy printing parameters individually
2682 for different types of display (backtrace, error, application).
2683 (These should of course be customizable!)
2685 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
2686 clear the CHECK-flags.
2688 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2690 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
2692 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2694 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
2695 from pairs with a GLOC in the car.
2697 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
2698 otherwise `symbol-hash' will behave badly.
2699 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
2700 we get segmentation fault!
2702 * symbols.c: Added #include "weaks.h". New functions:
2703 `builtin-bindings' and `builtin-weak-bindings'. (These will be
2704 moved to an extraneous library when we split libguile.)
2706 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2708 * filesys.c (scm_stat): stat now takes fport arguments too as
2709 documented in the manual.
2711 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2713 * debug.c (scm_single_step): Bugfix: Call continuation with
2714 scm_call_continuation instead of throwing to it.
2716 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
2718 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
2719 argument wasn't declared to be optional.
2721 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2723 * stime.c (scm_init_stime): Add feature "current-time".
2725 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
2727 * throw.h: prototype for scm_exit_status.
2728 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
2729 args to derive an exit status. Allows (quit) to work from a
2731 (scm_exit_status): new function.
2734 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2736 * eval.c (scm_deval): Removed some old code.
2737 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
2739 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
2742 * symbols.c (msymbolize): Bugfix: Must initialize property list to
2745 * procs.c: Introduce the existent C function scm_thunk_p at the
2746 Scheme level as well.
2748 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2750 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
2751 used from C to easily lookup the value of a symbol in the current
2754 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2756 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
2757 scm_init_unif in this file. This will also fix a previous problem
2760 * configure.in: Added AM_MAINTAINER_MODE
2762 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2764 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
2767 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
2769 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
2770 source files that are not always included in libguile but should
2771 have their dependencies calculated by automake. This variable is
2772 recognized by automake, no further magic is needed.
2773 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
2774 to deal exclusively with *.lo files, as it seems. The *.o files
2775 are built automatically when the corresponding *.lo file gets
2778 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
2780 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
2783 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
2785 * unif.c (scm_array_set_x): minor change to argument error checking.
2787 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
2789 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
2790 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
2791 They should only be included in the library at configure.in's
2793 (libguile_la_LDADD): Include the appropriate .lo files here.
2794 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
2795 so we know when to build them (and their .lo bretheren).
2796 * configure.in (LIBLOBJS): New substituted variable. We let
2797 configure decide which .o files to include in LIBOBJS, and then
2798 put the corresponding list of .lo files in LIBLOBJS. The latter
2799 is what we pass to libtool.
2800 * Makefile.in, configure: regenerated.
2802 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
2804 * symbols.c (scm_sysintern0): New function. Contains the core of
2805 old scm_sysintern but doesn't take a second value argument.
2806 (scm_sysintern): Now uses scm_sysintern0.
2807 (scm_sysintern_no_module_lookup): Renamed to
2808 scm_sysintern0_no_module_lookup and doesn't take a second value
2809 argument any longer.
2811 * symbols.h (scm_sysintern0: Added declaration.
2813 * options.c (scm_init_opts): Use scm_sysintern0 instead of
2814 scm_sysintern when interning option keys. Otherwise we risk
2815 destroying the values of already interned variables.
2817 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
2818 scheme-level boolean (use SCM_NFALSEP).
2820 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
2822 (scm_backtrace): New function. (C version of old function from
2823 boot-9.scm) Motivation: Make it possible to display backtraces
2824 without depending on boot-9.scm. (I'm uncertain if this
2825 motivation is good enough...)
2827 * root.h (scm_root_state): Add member the_last_stack_var.
2828 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
2830 * root.c (mark_root): Mark scm_the_last_stack_var.
2832 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
2835 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
2837 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
2838 1. mark_lazy_catch didn't mark the smob.
2839 2. Both functions above have standard variants:
2840 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
2841 free_lazy_catch --> scm_free0.
2843 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
2845 * throw.c (scm_internal_lazy_catch): New function.
2846 (scm_lazy_catch): Rewritten to use it.
2847 (scm_ithrow): Handle the new lazy catch representation.
2848 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
2849 that doesn't have a jmpbuf is a lazy catch clause.
2850 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
2851 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
2852 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
2854 (scm_init_throw): Register the new lazy-catch smob type.
2855 * throw.h (scm_internal_lazy_catch): decl for new function.
2857 * throw.c (scm_internal_catch): Doc fixes.
2859 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
2860 configure.in. Including this might cause problems if applications
2861 that link against libguile include their own copies of alloca, but
2862 if they're using autoconf, they should be adding libguile to LIBS
2863 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
2864 the copy in libguile, and things will be okay. (I think.)
2866 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2868 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
2870 strop.h: move prototypes too.
2872 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
2874 * posix.c (scm_init_posix): don't intern EINTR since it's now done
2877 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
2878 etc. I deleted them from filesys.c long ago, but didn't
2879 notice they were here too (although ineffective since
2880 sys/stat.h wasn't included).
2882 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
2884 * eval.c: Don't define alloca in GCC case. gcc will automatically
2885 use __builtin_alloca if appropriate.
2887 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
2889 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
2890 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
2891 that values of automatic variables are preserved. See comments
2892 for safe_setjmp for details.
2894 Change from Thomas Morgan:
2895 * variable.c: Include eq.h.
2896 (var_equal): New function.
2897 (variable_smob): Use var_equal as the discriminator for variables.
2899 * throw.c (s_throw): Remove extraneous declaration.
2901 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
2902 * eval.c: Add necessary CPP cruft to support that.
2903 * configure, Makefile.in, scmconfig.h.in: regenerated.
2905 Change from Thomas Morgan:
2906 * procprop.c (scm_procedure_properties): Convert the Scheme
2907 boolean returned by scm_procedure_p into a C boolean before using
2908 it as a condition for SCM_ASSERT.
2909 (scm_procedure_property): Likewise.
2911 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
2912 indications of Unixness.
2915 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
2917 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
2919 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
2921 * read.c (scm_lreadr): use scm_misc_error to improve one of the
2922 "unknown # object" error messages.
2924 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
2925 (scm_i_index) and declare it static. Add a 'direction' argument
2926 to indicate what way the search should go.
2927 (scm_i_index): throw out-of-range error instead of wrong-type-arg
2929 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
2930 strop.h: remove scm_i_index, scm_i_rindex prototypes.
2932 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
2934 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
2936 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
2937 to avoid clash with various scsh forks.
2939 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
2941 The following two changes (ramap.c, throw.c) are motivated by the
2942 apparent unportability of forward declarations of static arrays of
2943 the form `static foo bar[];'.
2945 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
2946 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
2948 * throw.c (scm_throw): Moved above scm_ithrow.
2950 * options.h: Removed the extern declarations of scm_yes_sym and
2951 scm_no_sym since these are static.
2953 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
2955 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
2957 * Makefile.am: remove AWK=@AWK@.
2958 Add a rule for generating errnos.list.
2959 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
2961 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
2962 don't extract errnos, just set a variable (avoids the
2963 need to recompile error.c just because configure is run.)
2965 * unif.h: update prototypes.
2966 * unif.c (scm_uniform_array_read,write): change the offset and
2967 length arguments to start and end, for consistency.
2969 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
2971 * ioext.h: update prototypes.
2972 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
2973 scm_read_line_x, it's a more general procedure using an
2974 interface from scsh. read-line and read-line! are now defined
2976 Note that the new read-line trims the terminator
2977 by default, previously it was appended to the returned string. An
2978 optional argument specifies how to process the terminator (scsh
2979 compatible). For the old behaviour: (read-line port 'concat).
2980 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
2981 returns a pair, but is converted to multiple values if the scsh
2984 socket.h: update prototypes.
2985 * socket.c (scm_recvfrom): for consistency with other procedures,
2986 take start and end as separate optional arguments.
2987 (scm_recv, scm_recvfrom): don't allow the second argument
2988 to be a size, only a buffer. Change the scheme names to
2989 recv! and recvfrom!. Don't return the buffer.
2991 * ioext.h, posix.h: move prototypes too.
2992 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
2993 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
2994 "read.h" and "unif.h".
2995 * ioext.c: include "chars.h"
2997 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
2999 * dynl.c: The dynamic linking and module registration functions
3000 are now defined even when dynamic linking is not available for the
3001 host system. Some of their functionality can be done without
3002 dynamic linking; when it's really needed, they throw errors.
3004 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
3006 * configure.in: Only define DYNAMIC_LINKING when one of the system
3007 dependent functions is detected.
3008 * dynl.c (scm_dynamic_func): New function to get the address of a
3009 function in a dynamic object.
3010 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
3011 produced by scm_dynamic_func as the thing to call.
3013 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
3015 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
3016 (scm_register_module_xxx, scm_registered_modules,
3017 scm_clear_registered_modules): New functions.
3019 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
3021 * symbols.c (scm_sysintern): Renamed to
3022 scm_sysintern_no_module_lookup.
3023 (scm_sysintern): New function to take the place of the old
3024 scm_sysintern. It uses the current toplevel lookup closure to give
3025 the symbol its value. This is a temporary hack to put packages
3026 like gtcltk into their own module.
3027 (scm_can_use_top_level_lookup_closure_var): New variable to tell
3028 us whether `scm_top_level_lookup_closure_var' has been initialized
3030 * eval.c (scm_init_eval): Set it.
3032 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
3034 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
3035 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
3037 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
3039 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
3040 scm_sys_dup): deleted: FD capability will be added to other
3042 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
3043 scm_fd_free, fd_smob, scm_intern_fd.
3044 (scm_open): renamed from scm_sys_open. Return a port instead of
3045 an FD object. Make the mode argument optional.
3046 (scm_sys_create): deleted, it's just a special case of open.
3047 (scm_init_filesys): move interning of constants O_CREAT etc.,
3048 here (were previously using SCM_CONST_LONG macro).
3049 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
3051 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
3052 include "fports.h" and <stdio.h>
3053 (scm_stat, scm_select): don't support FD objects.
3055 * error.h: adjust scm_syserror_msg prototype.
3056 * error.c (scm_syserror_msg): take an extra argument for errno.
3057 Using the global value didn't always work, since it could be
3058 reset by procedure calls in the message or args arguments.
3060 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
3061 I don't understand why the check was there (and what about the
3064 * strop.c (scm_string_copy): allow shared substrings to be copied.
3066 * unif.h: corresponding change to prototypes.
3067 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
3068 recognize two new optional arguments: offset and length. Allow
3069 the port argument to be an integer (file descriptor, for scsh).
3070 Include <unistd.h> for "read" prototype.
3072 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
3074 * socket.c: don't include filesys.h.
3076 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
3078 * Makefile.am: add AWK=@AWK@ (?)
3080 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
3082 Add a rule to generate errnos.c from errnos.
3083 * error.c (scm_init_error): include errnos.c.
3084 * errnos_cnvt.awk: new file, converts the list of errno codes to
3086 * errnos_get.c: new file.
3087 * errnos.default: new file, contains errnos to try if they can't
3088 be extracted from errno.h.
3089 * configure.in: if using GCC, try and extract errno codes from
3093 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
3095 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
3096 * Makefile.am: Made libguile into a libtool library.
3097 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
3098 Set libtool_libs to indicate that libguile is a libtool library.
3099 See guile/ChangeLog for details.
3100 * .cvsignore: ignore "*.lo", the libtool library objects.
3102 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
3104 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
3105 use htons in getservbyport argument.
3107 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
3109 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
3110 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
3113 * objprop.c (scm_object_property): No need to take the CDR of the
3114 value returned by scm_object_properties, since Aug 20 change.
3116 * configure.in: When checking for struct linger, #include
3117 <sys/types.h> as well as <sys/socket.h>. I've never known
3118 <sys/types.h> to cause any portability problems, and Solaris's
3119 <sys/socket.h> needs it.
3120 * configure: Rebuilt.
3122 I think the Sun compiler has chosen a perverse way to interpret
3123 ANSI declarations combined with K&R definitions. We'll
3124 appease it a little bit. But when it invades France, we fight.
3125 * print.c (scm_iprlist): Change 'tlr' argument to an int.
3126 * print.h (scm_iprlist): Here too.
3127 * numbers.c (scm_divbigdig): Change definition to match
3128 declaration in numbers.h.
3129 * unif.c (scm_makflo): Change definition to match declaration in
3132 * init.c (scm_boot_guile): Don't return the value of
3133 scm_boot_guile_1. This function doesn't return a value;
3134 scm_boot_guile_1 doesn't return a value (or return at all).
3136 * eval.c (unmemocopy): Add a semicolon to appease the Sun
3139 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
3140 compile. I have a feeling this function is a bad idea anyway ---
3141 one should always test for features, not systems.
3143 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
3144 semicolons. Only pure luck kept this from being noticed earlier.
3146 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
3148 * socket.c (scm_recvfrom): Added missing semicolon.
3150 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
3152 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
3153 the buffer and start and end positions for scsh networking
3156 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
3158 * configure.in: Revert previous change to this file; the problem
3159 is due to transient automake weirdness.
3160 * configure: Rebuilt.
3162 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
3163 PLUGIN/guile.libs. configure generates the latter from the former.
3164 * Makefile.in: Rebuilt.
3166 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
3167 need this if we install scripts, like guile-snarf.
3168 * configure: Rebuilt.
3170 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
3172 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
3174 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
3176 * socket.c (scm_addr_vector): fix faulty scm_listify.
3178 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
3180 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
3181 style block comment is no longer considered an error.
3183 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
3185 * PLUGIN/guile.libs.in: New file.
3186 * PLUGIN/guile.libs: Removed from repository.
3187 * configure.in: Create PLUGIN/guile.libs from
3188 PLUGIN/guile.libs.in. This is for including additonal libraries
3189 needed for dynamic linking.
3190 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
3191 instead of PLUGIN/guile.libs.
3193 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
3195 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
3197 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
3198 occurrences of the given element from the list, not just the
3199 first. This is how the Emacs Lisp functions behave, how the
3200 analogous Common Lisp functions behave, and (I believe) how the
3201 older Maclisp functions worked. I realize that this change may
3202 break code, but it seemed better to break it before the Guile
3205 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
3206 Their prototypes were already present in gc.h, but they weren't
3208 (scm_init_storage): Initialize scm_protects.
3209 * root.c (scm_protects): New element of scm_sys_protects.
3211 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
3213 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3215 * libguile.h: Added #include "libguile/net_db.h".
3217 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
3218 30 change. That file is only meant for communication between the
3219 configuration process and load.c. If code linked against libguile
3220 wants to get at the paths mentioned in libpath.h, it can call
3221 functions declared in load.h.
3223 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3225 * libguile.h: Removed #include "libguile/fdsocket.h"
3227 * net_db.c: Added #include <sys/socket.h>.
3229 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
3231 * filesys.c (scm_input_waiting_p): use select in preference to
3232 FIONREAD, since the latter doesn't detect EOF.
3233 Throw error if neither select nor FIONREAD available.
3235 * socket.c (scm_connect): take a port, not a fd object.
3236 (scm_fill_sockaddr): throw an error if fam is not recognised.
3237 (scm_bind): use scm_fill_sockaddr.
3238 (scm_listen): take a port, not a fd object.
3239 (scm_accept): take and return a port. return #f in the car if
3240 address can't be got
3241 (scm_sock_fd_to_port): new procedure.
3242 (scm_socket): use scm_sock_fd_to_port.
3243 (scm_addr_vector): throw error if unrecognised address type.
3244 take an extra argument with the calling procedure name.
3245 (scm_getsockname): take a port. return #f if address can't be got.
3246 (scm_getpeername): take a port. return #f if address can't be got.
3247 (scm_recvfrom): take a port. return #f for address component if can't
3249 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
3250 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
3252 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
3254 * throw.c (scm_internal_catch): Make body funcs and handler funcs
3255 use separate data pointers, to allow them to be designed
3256 independently and reused.
3257 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
3258 Renamed from catch_body, catch_handler, and uncaught_throw; made
3260 (struct scm_catch_body_data): Renamed from catch_body_data; moved
3262 (scm_catch): Use the above.
3263 (scm_throw): Don't bother printing a message for an uncaught
3264 throw; we establish a default handler in init.
3265 * throw.h (scm_internal_catch): Prototype updated.
3266 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
3268 (struct scm_body_thunk_data): New structure, used as data
3269 argument to scm_body_thunk.
3270 * init.c (struct main_func_closure): New structure, packaging up
3271 the data to pass to the user's main function.
3272 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
3273 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
3274 scm_internal_catch to establish a catch-all handler, using
3275 scm_handle_by_message. This replaces the special-case code in
3277 (invoke_main_func): Body function for scm_internal_catch; invoke
3278 the user's main function, using the main_func_closure pointer to
3279 decide what to pass it.
3280 * root.c (struct cwdr_body_data): Remove handler_proc member.
3281 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
3282 (cwdr_handler): Removed.
3284 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3286 * socket.h (SCM_P): update bind prototype.
3287 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
3288 include "feature.h".
3289 (scm_socket): return a port, not a file descriptor object.
3290 include "fports.h" and <unistd.h>
3291 (scm_bind): take a port, not a file descriptor object.
3292 take an extra argument for address args.
3294 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
3295 INADDR_NONE, INADDR_LOOPBACK.
3297 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
3299 * init.c: include net_db.h and not fdsocket.h.
3300 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
3302 * Makefile.am: corresponding changes.
3303 * socket.h: renamed from fdsocket.h, fix names.
3304 * net_db.h: renamed from socket.h, fix names.
3305 * socket.c: renamed from fdsocket.c.
3306 remove _sys from procedure names.
3307 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
3308 add "socket" to features list.
3309 * net_db.c: renamed from socket.c.
3310 remove _sys from procedure names.
3311 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
3312 add "net-db" to features list.
3313 include "net_db.h". don't include <sys/socket.h> or
3316 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3318 * tags.h (scm_tags): Removed comma at end of last enumerator.
3320 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
3322 Don't use GCC extensions to allocate space for debugging frames.
3323 (Here he goes again! Why do we put up with this?!)
3324 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
3325 an scm_debug_info structure, not an in-line array of them. Add
3326 'info' member, to say how many vect elements we've used, for eval
3328 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
3329 a new variable debug_info_end to mark the end of vect, instead of
3330 the address of the 'info' pointer itself.
3331 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
3332 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
3333 (SCM_APPLY): Explicitly allocate space for debug.vect.
3334 * debug.c (scm_m_start_stack): Same, for vframe.vect.
3335 * stacks.c: Adjusted for new debug frame structure.
3336 (RELOC_INFO, RELOC_FRAME): New macros.
3337 (stack_depth, read_frames): Use them, and new scm_debug_frame
3338 element 'info', instead of magically knowing that eval frames have
3339 an info pointer sitting after vect.
3340 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
3342 (scm_init_stacks): Formatting tweaks.
3344 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
3346 Give GCC more control flow information, so it can be sure that
3347 variables aren't used uninitialized.
3348 * error.h (scm_error, scm_syserror, scm_syserror_msg,
3349 scm_sysmissing, scm_num_overflow, scm_out_of_range,
3350 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
3351 scm_misc_error): Tell GCC that these functions never return.
3352 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
3353 out the field type, call abort if SCM_ASSERT returns, to placate
3355 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
3356 scm_wta ever returns. We can't handle this case anyway, and this
3357 gives the optimizer more information.
3358 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
3359 scm_wta ever returns.
3361 In some cases, the code is fine, but GCC isn't smart enough to
3362 figure that out; this usually happens when one variable is only
3363 initialized and used when a particular condition holds true, and
3364 we know that condition will never change within a given invocation
3365 of the function. In this case, we simply initialize the variables
3366 to placate the compiler, hopefully to a value which will cause a
3367 crash if it is ever actually used.
3368 * print.c (scm_iprin1): Initialize mw_pos.
3369 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
3370 * throw.c (scm_ithrow): Initialize dynpair.
3371 * unif.c (scm_uniform_vector_ref): Initialize cra.
3372 * struct.c (init_struct): Initialize prot.
3373 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
3375 * strports.c (scm_eval_0str): Don't return uninitialized garbage
3376 if EXPR contains no expressions.
3378 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
3380 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
3381 cause an infinite loop (???). So much for the algebraic
3382 equivalency of variable-sized arrays and alloca...
3384 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
3386 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
3387 a SCM boolean, not a C boolean.
3389 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
3391 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
3392 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
3393 rules for raising scm_mtrigger. Previously, unfortunate but not
3394 unlikely circumstances could result in almost constant invokation
3395 of the gc. Now, this situations should be less likely, but they
3396 are not prevented completely.
3398 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
3400 * numbers.c (scm_fuck): Procedure removed; looks like old test
3402 * numbers.h: Prototype removed.
3404 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
3406 * debug.h (scm_debug_frame): Change `vect' member from an in-line
3407 array to a pointer, to match my Nov 21 change in eval.c.
3409 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3411 * libguile.h: Added #include "libguile/backtrace.h", #include
3412 "libguile/stacks.h".
3414 * strings.c (scm_string scm_make_string scm_string_ref
3415 scm_string_set_x scm_string_equal_p scm_string_append):
3416 Bugfix according to scm patch from Aubrey Jaffer:
3417 Corrected long-standing
3418 (not (eqv? (integer->char 128)
3419 (string-ref (make-string 1 (integer->char 128)) 0)))
3420 bug found by John Kozak <jk@noontide.demon.co.uk>.
3422 * strports.c, strports.h: Make scm_eval_0str return the value of
3423 the last expression evaluated (previously, it returned void).
3425 * strports.c, strports.h: New function: scm_read_0str. Does what
3428 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
3430 * simpos.c (scm_getenv): return #f if string can't be found in the
3431 environment instead of throwing an exception, for compatibility
3432 with numerous other systems.
3434 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
3436 * Makefile.am (.c.x): Use guile-snarf.
3437 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
3439 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
3441 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3443 * backtrace.c (scm_display_error_message): Made non-static, and
3444 renamed from display_error_message.
3445 * backtrace.h (scm_display_error_message): Added extern decl.
3446 * throw.c (uncaught_throw): Use it to display the error message.
3448 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
3450 * inet_aton.c: Use #if 0, not #ifdef 0.
3452 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
3454 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
3455 to convert the returned value.
3456 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
3457 the offset argument.
3459 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
3461 Add new interface to catch/throw, usable from C as well as
3463 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
3464 (scm_internal_catch): New function, replaces...
3465 (scm_catch_apply): Deleted.
3466 * throw.c (scm_catch_apply): Deleted; replaced with a more general
3467 mechanism which is a bit more code, but can be used nicely from C
3468 and implement the Scheme semantics as well.
3469 (scm_internal_catch): This is the replacement; it's named after
3470 the analogous function in Emacs.
3471 (scm_catch): Reimplemented in terms of the above.
3472 (struct catch_body_data, catch_body, catch_handler): New
3473 functions, used by scm_catch.
3474 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
3475 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
3476 support for new cwdr.
3478 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
3481 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
3483 * acconfig.h: Added DYNAMIC_LINKING symbol.
3484 * configure.in: Add option and checks for dynamic linking.
3485 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
3486 dynl.h: New files for dynamic linking support.
3487 * Makefile.am (libguile_a_SOURCES):
3489 (modinclude_HEADERS): Added "dynl.h".
3490 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
3492 * init.c (scm_boot_guile_1): Call
3493 scm_init_dynamic_linking to initialize dynamic linking support.
3495 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
3497 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
3498 (as we Schemers say). It needs to be global, so that I can tweak
3499 it for the proper operation of unexec.
3500 (scm_boot_guile_1_live): New variable, see above.
3502 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
3504 * guile-snarf.sh: Removed.
3505 * PLUGIN/guile.libs: Added dependency for -lm.
3506 * acinclude.m4: Renamed from aclocal.m4.
3507 * PLUGIN/greet: Removed.
3508 * Makefile.am, aclocal.m4: New files.
3509 * configure.in: Updated for Automake.
3511 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
3513 * eval.c (scm_definedp): Use top_level_lookup_closure_var
3514 and not top_level_lookup_thunk_var.
3516 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
3518 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
3520 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
3522 * eval.c (scm_definedp): Incompatibly changed to be a builtin
3523 Scheme function, instead of syntax. Single argument is now a
3526 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
3528 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
3529 scm_ra_divide): Properly terminate statements passed as arguments
3530 to IVDEP macros. (Thanks to Bernard Urban.)
3532 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
3533 with non-constant sizes. (Thanks to Bernard Urban.)
3535 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3537 It's an "eval closure", not an "eval thunk." A thunk is a
3538 function of no arguments.
3539 * root.h (struct scm_root_state): Renamed
3540 top_level_lookup_closure_var from top_level_lookup_thunk_var.
3541 (scm_top_level_lookup_closure_var): Renamed from
3542 scm_top_level_lookup_thunk_var.
3543 * root.c (mark_root): Uses changed.
3544 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
3545 * init.c (scm_start_stack): Uses changed.
3546 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
3547 Change scheme-visible name to *top-level-lookup-closure* from
3548 *top-level-lookup-thunk*.
3550 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
3552 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
3553 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
3555 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
3557 * gc.c (struct scm_heap_seg_data): Doc fixes.
3559 * gc.c (scm_gc_sweep): Empty all segments' freelists before
3560 sweeping. Then, prepend each segment's free cells to its
3561 freelist, rather than wiping out the old value. (Thanks to Marius
3564 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
3565 scm_check_freelist, scm_debug_newcell): New functions and
3566 variables, for debugging freelist problems.
3567 * pairs.h (SCM_NEWCELL): New debugging version added.
3568 * gc.h (scm_debug_newcell): Added extern declaration, used by
3569 debugging version of SCM_NEWCELL.
3571 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
3573 On some systems <libc.h> conflicts with <unistd.h>, and should not
3574 be #included at all.
3575 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
3576 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
3577 * configure.in: Call it.
3578 * posix.c, filesys.c: Use its results to decide whether or not to
3580 * configure, scmconfig.h.in: Rebuilt with autoconf and
3583 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
3585 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
3586 pointer to the stdio stream before calling scm_setbuf0, so the
3587 latter will be able to retrieve it. I'm surprised this didn't
3588 segfault earlier. (Thanks to Christopher Lee.)
3590 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3592 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
3595 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3597 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
3598 number of stack narrowing specifier pairs. The first specifier in
3599 a pair controls inner border, the second the outer border. A
3600 number means cut that number of frames, a procedure object means
3601 cut until that object is found in operator position in a frame.
3603 * root.c (cwdr): Bugfix.
3605 * read.c: Recording of positions disabled by default.
3607 * procs.c (scm_closure_p): New function.
3609 * posix.c (scm_tmpnam): New function.
3611 * load.c: Added #include "throw.h".
3612 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
3615 * load.c, load.h (scm_read_and_eval_x): New function.
3617 * eval.c: Renamed debug option "deval" to "debug".
3619 (scm_eval_x): `eval!' is no longer accessible from the scheme
3620 level. Motivation: We can't allow operations which introduce
3621 glocs into the scheme level. Guile's type system can't handle
3622 these as data. Use `eval' or `read-and-eval!' as replacement.
3624 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
3625 SCM_CONSP since this is a macro!; Set vframe.prev to
3626 scm_last_debug_frame instead of 0. In this way we can look
3627 "above" the virtual start stack frame if we wish.
3628 (scm_debug_hang): New function: Useful for debugging Guile in
3629 certain tricky situations. Will probably be removed later...
3631 * debug.h: Changed semantics of debug option "backtrace". This
3632 option now only indicates whether we want automatic backtrace at
3635 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3637 * ports.c: #include "filesys.h"
3638 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
3640 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
3641 Motivation: This is system specific code which is related to file
3642 I/O. It also may use select. Added code by Gary Houston to
3643 detect presence of character in stdio buffers.
3645 * libguile.h: #include "libguile/libpath.h"
3647 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
3648 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
3649 SCM_SITE_DIR; Install libpath.h among the other include files.
3651 * load.c, load.h (scm_sys_package_data_dir): New function.
3653 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3655 * stacks.h: Bugfix: Don't use tail-array length field as stack
3656 length field! This screwed GC.
3658 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3660 * _scm.h: Added #ifndef around definition of macros min and max.
3662 * __scm.h: Added hooks for threads to plugin to in ints protection
3663 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
3664 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
3665 the main code in these macros duplicated and spread over multiple
3666 files. Renamed SCM_THREADS_SWITCHING_CODE ->
3667 SCM_THREAD_SWITCHING_CODE.
3669 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
3671 * snarf.h: New file.
3672 * guile-snarf.sh: New file.
3673 * Makefile.in (inner_h_files): Added snarf.h
3674 (ancillary, install, uninstall, distclean): Added actions for
3676 (.c.x): Use guile-snarf.
3677 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
3678 (gen_c_files): Note that these depend on guile-snarf.
3679 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
3680 now in "snarf.h". Added #include "snarf.h" to get them.
3681 * libguile.h: Added #include "snarf.h".
3682 (Patches applied and tweaked by Jim Blandy.)
3684 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
3686 * socket.c: Use K&R style declaration for 'close'; the GNU coding
3687 standards suggest against providing prototypes for system
3688 functions. Thanks to Greg Troxel.
3690 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
3692 * strports.c (scm_eval_0str): New function.
3693 #include "read.h", to get prototype for scm_read.
3694 * Makefile.in (strports.o): Update dependencies.
3695 * strports.h: New prototype.
3697 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
3698 scheme name from "int?" to "integer?". It seems to do the job.
3699 * numbers.h: Rename prototype too.
3700 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
3703 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
3704 scm_num_eq_p): Rename these according to R4RS conventions: call
3705 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
3706 to making libguile R4RS compliant without ice-9...
3708 * load.c (scm_sys_search_load_path): Search for files under all
3709 extensions listed in the %load-extensions variable. If FILENAME
3710 is absolute, return it unchanged, without searching the load path.
3711 (scm_loc_load_extensions): New variable, pointing to
3712 %load-extensions' value cell.
3713 (scm_init_load): Initialize it, and the value it points to.
3714 (scm_primitive_load_path): Improve error reporting.
3716 * load.c (scm_loc_load_hook): New variable, pointing to value cell
3717 of new Scheme variable %load-hook.
3718 (scm_primitive_load): Apply %load-hook to filename.
3720 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
3722 * configure.in: add tests for figuring out whether buffered data
3723 is available in a FILE structure, which is needed by char-ready.
3725 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
3728 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
3729 exceptions using misc_error instead of syserror. It seems a bit
3730 odd to throw an exception if a string can't be found in the
3731 environment, but it's consistent with open-file, stat etc.
3732 (simpos.h): remove sys_ from getenv.
3734 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
3735 occurs, throw an error instead of returning errno. Return value
3737 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
3739 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
3741 * filesys.c (scm_stat2scm): derive file type and permissions from
3742 the stat mode and append them to the returned vector.
3743 There isn't much overhead in doing this and it avoids the need to
3744 work with S_IRUSR et al. in Scheme.
3745 Define symbols scm_sym_regular etc.
3746 (scm_init_filesys): don't intern S_IRUSR etc.
3748 * load.c: change s_try_load and s_try_load_path to s_primitive_load
3749 and s_primitive_load_path.
3751 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
3753 * error.h: don't declare error symbols. prototype for scm_misc_error.
3755 * stackchk.c (scm_stack_overflow_key): defined here instead of in
3758 * error.c: use SCM_SYMBOL to set up error keys.
3759 scm_misc_error: new procedure.
3761 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
3763 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
3764 between `#!' and `!#' is ignored.
3765 (skip_scsh_block_comment): New function.
3767 * feature.c (scm_set_program_arguments): New argument, FIRST.
3768 * feature.h: Update prototype.
3769 * init.c (scm_boot_guile_1): Pass new argument to
3770 scm_set_program_arguments.
3772 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
3774 * init.c (scm_start_stack): Don't initialize scm_progargs here.
3775 (scm_boot_guile): Call scm_set_program_arguments here, later than
3776 the old initialization.
3778 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
3779 initialization procedure.
3780 - Delete in, out, err arguments; there are other perfectly good
3781 ways to override these when desired.
3782 - Delete result argument; this function shouldn't ever return.
3783 - Rename init_func argument to main_func, for less confusion.
3784 - Delete boot_cmd argument; main_func is more general.
3785 -Add 'closure' argument, to help people pass data to main_func
3786 without resorting to global variables.
3787 - Abort if reentered; don't bother returning an error code.
3788 - Call scm_init_standard_ports to set up the default/current
3789 standard ports; no need to pass them to scm_start_stack.
3790 - Remove code to evaluate the boot_cmd, and start the repl; let
3791 the user do something like that in main_func if they want.
3792 - Remove code to package up a return value; main_func can do any
3794 - Call exit (0), instead of returning.
3795 (scm_start_stack): Don't initialize the I/O ports here; that's
3796 weird. Delete in, out, err arguments. Move guts to
3797 scm_init_standard_ports, scm_stdio_to_port.
3798 (scm_init_standard_ports): New function, to set up current and
3799 default standard ports.
3800 (scm_start_stack, scm_restart_stack): Make these static.
3801 * init.h (scm_boot_guile): Adjust declaration.
3802 (scm_start_stack, scm_restart_stack): Remove externally
3803 visible declarations for these.
3804 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
3806 * fports.c (scm_stdio_to_port): New function. Its guts used to be
3807 written out several times in scm_start_stack.
3808 * fports.h: New declaration for the above.
3810 * feature.c (scm_set_program_arguments): New function.
3811 * feature.h: New declaration for the above.
3813 * ports.c: Formatting tweak.
3815 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
3817 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
3818 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
3819 for obtaining the address of a car or cdr field. Motivation:
3820 &SCM_CXR make assumptions about the internal structure of the
3823 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
3824 Motivation: see SCM_CXRLOC.
3826 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
3827 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
3828 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
3829 Motivation: Safer use. Some other macros are defined in terms of
3830 these operations. If these are defined using the SCM_SETCXR
3831 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
3832 to inefficiency and an <e1> with side-effects could potentially
3833 break. Also, these particular operations are heavily utilized in
3834 the garbage collector. In unoptimized code there will be a
3837 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
3838 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
3839 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
3840 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
3841 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
3842 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
3843 vports.c: Cleaned up use of pairs: Don't make any special
3844 assumptions about the internal structure of selectors and
3845 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
3846 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
3847 (Among other things, this change makes it easier to build Guile
3848 with certain compilers which have problems with casted lvalues.)
3850 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3852 * stacks.c: Improve selection of relevant stack frames when making
3853 a stack object. Introduce one level of indirection in the stack
3854 object to make it possible to "narrow" to a certain region of the
3855 stack. This facilitates making use of more clever algorithms (not
3856 implemented) for selecting relevant frames and gives a cleaner
3857 design since selection of frames can be done independently of
3858 extraction of frames from the real stack.
3859 (scm_stack_id): Also take #t as argument which means look at
3862 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
3863 Turn n_tail into an integer directly representing current number
3864 of frames in stack. Add field tail.
3866 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
3868 * debug.c (scm_make_memoized): Made it available at scheme level.
3869 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
3870 SCM_NIMP before applying heavier predicates in argument checking.
3871 (scm_local_eval): Also take memoized object as argument.
3873 * backtrace.c (scm_display_error): Just a safety measure: Stacks
3874 aren't created with zero length, but should such a strange
3875 creature suddenly turn up...
3877 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
3879 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
3880 `del', for the sake of C++ compilers. (Patch applied by JimB.)
3882 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
3884 * variable.c (scm_make_variable): Make the name hint optional, as
3886 (anonymous_variable_sym): Renamed from variable_sym. All uses
3889 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
3890 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
3891 of scm_primitive_load_path was also changed to
3892 "primitive-load-path", from "%try-load-path". Callers changed.
3893 We'd like to respect the convention that a function named
3894 "try-mumble" should behave just like the function called "mumble",
3895 but return #f instead of signalling some error.
3896 * load.h: Rename prototypes.
3898 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3900 * print.c (make_print_state, grow_print_state), print.h: Modified
3901 the print state representation: Don't use a tail array for
3902 recording of circular references. Resizing of the print state
3903 structure invalidates the print state pointer. To avoid passing
3904 around an indirect print state reference to all printing
3905 functions, we instead let the print state reference a resizable
3908 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
3910 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
3911 Don't crash when passed an improper list terminated by a
3912 non-immediate value.
3914 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
3916 Allocate data for structures on an eight-byte boundary, as
3917 required by the tagging system.
3918 * struct.c (alloc_struct): New function.
3919 (scm_make_struct, scm_make_vtable_vtable): Call it.
3920 * struct.h (scm_struct_n_extra_words): Bump to 3.
3921 (scm_struct_i_ptr): New "field".
3922 * gc.c (scm_gc_sweep): When we need to free the data, use the
3923 information stored by alloc_struct to find the beginning of the
3924 block allocated to the structure, so we can free it.
3926 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3928 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
3931 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
3932 (scm_debug_info): New member: id.
3934 * stacks.c: Stacks are now represented as structs; Stacks have an
3935 id given to them by `start-stack'.
3936 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
3938 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
3939 Changed stack representation.
3941 * debug.c (scm_procedure_name): Try procedure property `name' for
3942 compiled closures aswell.
3944 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
3946 * eval.c: scm_i_name moved to gsubr.c
3947 (scm_m_define): Record names of all kinds of procedure
3948 objects. (Earlier, only closures were recorded.)
3950 * procprop.h: Added declaration of scm_i_name.
3952 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
3953 (scm_make_gsubr): Record names of compiled closures.
3955 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
3957 * debug.c, debug.h: Removed obsolete code.
3959 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
3960 stacks.c: Renamed regs --> scm_contregs.
3962 * print.c (scm_free_print_state): Cleanup print state before
3963 returning it to pool. It is better to do it here than in
3964 scm_prin1 since scm_prin1 is called often.
3966 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
3967 s_set_source_property_x): Check that first argument is a pair or a
3970 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
3971 scm_i_line, scm_i_column and scm_i_breakpoint global.
3973 * init.c: Added #include "backtrace.h" and #include "stacks.h".
3974 (scm_boot_guile_1): Added calls to scm_init_backtrace and
3977 * debug.h: Added debug object smob declaration and macro
3980 * configure.in: Build with backtrace.o and stacks.o if debug
3983 * Makefile.in: Added entries for new files: backtrace.c,
3984 backtrace.h, stacks.c and stacks.h.
3986 * symbols.c (scm_sym2ovcell): Fixed documentation.
3988 * _scm.h (min, max): Added.
3990 * async.c: Moved `min' macro to _scm.h.
3992 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
3993 SCM_BACKTRACE_INDENT.
3995 * eval.c: Added new debug options `maxdepth' and `indent'.
3997 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
3999 * print.h: Added selector SCM_PRINT_STATE.
4001 * print.c: New functions: scm_make_print_state,
4002 scm_free_print_state.
4004 * print.h: Added declarations for scm_make_print_state,
4005 scm_free_print_state.
4007 * debug.c (scm_m_start_stack): New acro.
4009 * debug.h: Small cleanup.
4011 * init.c (scm_boot_guile_1): Moved scm_init_debug below
4014 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

4034 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
4035 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
4036 declare functions with prototypes. (Patch thanks to Marius
4039 More prototype-related changes from Marius Vollmer:
4040 * gdb_interface.h: Wrapped header file in #ifdef/#endif
4041 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
4042 * ports.h (ptobfuns): Added prototypes. This means some casting in
4044 * fports.c: Added casts for initializations, since the functions
4045 are defined to take FILE * as their stream argument, not SCM.
4046 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
4047 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
4048 to `char *str_data' to conform to prototype.
4050 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4052 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
4054 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
4056 * stime.c, stime.h: use SCM_P method.
4058 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4060 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
4061 be given at least two arguments. Insist that lst's last element
4062 be a list, but don't make any requirements of its predecessors.
4064 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
4066 * eval.c (scm_nconc2last): Revert last change; there seems to be
4067 other stuff going on here.
4069 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4071 * eval.c (scm_nconc2last): Make sure that each element of lst
4072 (which is a list of argument lists, except for the tail) is a
4073 proper list, i.e., finite and terminated by '().
4075 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
4077 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
4080 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
4081 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
4084 * vectors.c (scm_make_vector): Fill vectors with the undefined
4085 value, to help make Guile Scheme code more portable to other
4088 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
4089 * symbols.h, tags.h: Doc fixes.
4091 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
4093 * async.c (scm_take_signal): Doc fixes.
4095 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
4097 * numbers.c (scm_divbigint): When the remainder is zero, we don't
4098 want to subtract it from the modulus; we just want to leave it
4101 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
4103 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
4106 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
4108 * throw.c (scm_catch_apply): Finished implementation of
4111 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
4113 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
4115 (scm_init_filesys): set "i/o-extensions" feature.
4118 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
4120 * Makefile.in (root.o): Correct dependencies.
4122 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
4124 * Makefile.in: Added dependency entry for root.o.
4126 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
4127 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
4129 * init.c (scm_start_stack): Set initial root continuation number
4132 * procs.c: New function: scm_thunk_p.
4134 * procs.h: Added declarations of scm_thunk_p.
4136 * root.c: Renamed `call-with-new-root' -->
4137 `call-with-dynamic-root'.
4138 (cwdr): Removed allocation of new root state. This should be done
4139 separately by use of scm_make_root.
4140 (scm_apply_with_dynamic_root): New function: Does what it
4141 sounds like. Needed when spawning threads.
4143 * root.h: Added member last_debug_frame to root state.
4144 Added #include "libguile/debug.h"
4146 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
4147 arguments. The motivation is that code in root.c needs catch
4148 functionality, and we want to avoid code duplication.
4149 New functions: scm_catch, scm_lazy_catch. These are wrappers for
4150 scm_catch_apply. scm_lazy_catch is intended to introduce catch
4151 handlers that run without popping the stack into the dynwind
4154 * throw.h: Added prototypes for scm_catch_apply and
4157 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4159 * root.h (scm_root, scm_set_root): Decouple thread support details
4160 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
4161 SCM_SET_THREAD_LOCAL_DATA.
4163 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
4164 and tortoise scanning loop.
4166 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
4168 * Makefile.in: Rebuild dependencies.
4170 * libguile.h: #include "libguile/print.h" before "smob.h", since
4171 the latter uses the print_state structure.
4173 * throw.c (scm_ithrow): Use the correct variable when checking to
4174 see if a given element of scm_dynwinds is a valid catch.
4176 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
4177 structure, abort; don't just silently ignore the garbage.
4179 * _scm.h: #include "print.h" here, since it seems to be used just
4181 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
4182 strports.c, unif.h: Don't #include "print.h".
4184 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4186 * feature.h (scm_loc_features): Removed external declaration.
4187 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
4189 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4191 * feature.c (scm_init_feature): Added threads feature (needs to be
4192 initialized here, since features doesn't exist when
4193 scm_init_threads is called).
4195 * libguile.h: Added #include "libguile/../threads/threads.h".
4196 (This is a kludge to get thread support working. This should be
4199 * configure.in, acconfig.h: Added flags for thread support.
4201 * scmsigs.c: Define `signal' to be `pthread_signal' if using
4204 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
4205 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
4208 * _scm.h: Added conditional #include "threads.h"
4210 * __scm.h (SCM_ASYNC_TICK): Added call to macro
4211 SCM_THREADS_SWITCHING_CODE.
4213 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
4214 allocate the basic dynamic root object.
4215 (scm_boot_guile): Added call to scm_init_root.
4217 * root.c, root.h: Added root smob.
4218 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
4219 functions: Implements dynamic roots mostly according to spec in
4220 SCM manual. Main difference is that the second argument is a
4221 throw handler rather than an error "thunk".
4223 * root.h: Added declaration of scm_init_root.
4225 * root.c: Added #include "genio.h", #include "smob.h", #include
4226 "pairs.h", #include "throw.h", #include "dynwind.h", #include
4228 (scm_init_root): Added #include "root.x".
4230 * throw.c: Added #include "stackchk.h"
4231 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
4232 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
4233 can be used in scm_call_with_new_root; Added reenabling of stack
4234 checking when catching a throw.
4236 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
4238 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
4240 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
4241 element is not found, as per R4RS.
4243 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4245 * list.c: Doc fixes throughout.
4247 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
4249 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
4250 declare the char * to be const. Avoids a warning in rgx.c.
4252 * ports.h: spelling fix.
4254 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
4257 * load.c (scm_sys_try_load_path): throw an error if file not found
4258 (like it says it in NEWS).
4260 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
4262 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
4263 PROPS slot to '(), not #f; it's an empty alist.
4265 * throw.h, throw.c: Use SCM_P instead of #if hair.
4267 Remove special support for uncaught throws; see throw.c for
4269 * throw.c (uncaught_throw): New function.
4270 (scm_ithrow): Call uncaught_throw if we don't find a throw
4271 target; don't mess with scm_bad_throw_vcell.
4272 (scm_bad_throw_vcell): Variable deleted.
4273 (scm_init_throw): Don't initialize it.
4275 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
4278 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
4280 * numbers.c (scm_istr2int): If the number is short (as most
4281 numbers are), just call scm_small_istr2int to deal with it.
4282 (scm_small_istr2int): New function, created by un-#ifdefing the
4283 non-bignum version of scm_istr2int and renaming it.
4285 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
4287 * load.c (scm_sys_try_load): don't check whether value returned
4288 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
4289 Change the Scheme name from %try-load to primitive-load.
4291 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
4292 Can avoid passing a message, allowing it to be derived in the
4293 error handler (e.g., if we want to throw to the key both from
4296 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
4298 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
4299 references now have a new appearance which is more compact and
4300 also gives a clue about what the target of the reference is.
4301 By setting parameters in the print state, more fancy printing can
4302 be achieved. This is used by the (not yet commited) backtrace
4305 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
4307 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
4310 * print.c: Added #include "struct.h". Removed function
4313 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
4314 scm_iprin1. Removed prototype for scm_prlist.
4316 * arbiters.c (prinarb),
4317 async.c (print_async),
4318 debug.c (prindebugobj, prinmemoized),
4319 eval.c (prinprom, prinmacro),
4320 filesys.c (scm_fd_print, scm_dir_print),
4322 mallocs.c (prinmalloc),
4323 numbers.c, numbers.h (scm_floprint, scm_bigprint),
4324 smob.h (scm_smobfuns),
4325 srcprop.c (prinsrcprops),
4327 unif.c, unif.h (scm_raprin1, rapr1),
4328 variable.c (prin_var): Changed argument `int writing' to
4329 `scm_print_state *pstate'.
4331 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
4332 that it will be called before scm_init_print.
4334 * print.c (scm_prin1): Print states are now allocated when calling
4335 scm_prin1 and then passed around to all printing functions as an
4336 argument. A cache `print_state_pool' enables reuse of print
4338 (scm_make_print_state): New function.
4339 (scm_iprin1): Adaption to print states.
4340 (scm_iprlist): An initial "hare and tortoise" scan brings down
4341 time complexity to O (depth * N). (Better time complexity will be
4342 achieved when the printing code is completely rewritten.)
4344 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
4346 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
4347 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
4348 it gets done whether or not the cache variable has a value.
4350 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
4352 Distinguish #f and ().
4353 * __scm.h: #undef SICP.
4354 * pairs.h (SCM_EOL): Delete this definition, equating it with
4356 * tags.h (SCM_EOL): Give it a new definition here; I think I found
4357 the value it used to have. Doc fixes, too.
4359 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
4361 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
4362 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
4363 Lord's implementation of structs, allowing for tail arrays as
4364 described in the manual. Also fixed some bugs. (Both the interface
4365 and the implementation should be improved.)
4367 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
4369 * print.c, print.h: Closures now print like #<procedure foo (x)>.
4370 People who whish to see the source can do `(print-enable 'source)'.
4371 Removed #ifdef DEBUG_EXTENSIONS.
4373 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4375 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
4376 integer (assuming for now accepting an integer is a good thing).
4378 * error.c, fports.c: replace use of %S in lgh_error args with %s.
4379 %S will be used instead for write'ing arguments.
4381 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
4382 asserts. fix a few other asserts.
4383 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
4384 scm_uniform_vector_ref, scm_array_set_x,
4385 scm_dimensions_to_unform_array): change args in
4386 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
4387 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
4388 scm_substring_fill_x): likewise.
4389 gsubr.c (scm_gsubr_apply): likewise.
4390 eval.c (SCM_APPLY): likewise.
4392 * eval.c (4 places): replace scm_everr with lgh_error or
4395 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
4396 scm_memory_error): new procedures.
4397 scm_everr: deleted. can use scm_wta, dropping first two args.
4398 scm_error: convert NULL subr to SCM_BOOL_F.
4400 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
4403 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
4406 * error.c, error.h: new error keys: scm_arg_type_key,
4407 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
4409 scm_wta: reimplement using lgh_error instead of scm_everr.
4411 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
4413 * gdbint.c: scm_lread now has one more argument.
4415 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
4416 scm_port_\1; Added mutator scm_set_port_filename_x (used when
4417 loading source from non-file ports, which, e. g., happens when
4418 using the Emacs interface).
4420 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
4423 * read.c: Added code for recording of positions of source code
4424 expressions; New functions: recsexpr, scm_lreadrecparen;
4425 _scm_make_srcprops --> scm_make_srcprops
4426 (scm_flush_ws): Removed updating of positions counters. This work
4427 is already done by scm_gen_getc
4429 * read.h: Added prototype for scm_lreadrecparen
4431 * print.c: Added #include "alist.h"
4433 * eval.c: Added #include "hash.h"
4435 * eq.c: Added #include "ramap.h"
4437 * options.c: Documentation fixes.
4439 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
4440 (scm_init_srcprop): Adjusted size of initial source-whash. Name
4441 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
4442 --> scm_make_srcprops
4444 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
4445 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
4446 function calls in the definition of the whash access macros.
4448 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
4450 * init.c (scm_boot_guile): Add level of indirection to
4451 scm_boot_guile_1() to ensure that stack base pointer is properly
4452 initialized. There was no guarantee that variable i was the
4453 highest/lowest variable on stack (i.e. the call frame of
4454 scm_boot_guile was not completely protected from gc).
4456 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
4458 * ports.h (scm_port_table): put back file_name, it will be used to
4459 support debugging. Undo related changes in fports.c, ioext.c,
4462 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
4464 * ports.h (scm_port_table): remove file_name member for now, it seems
4466 * fports.c (scm_open_file): don't set file_name in PTAB.
4467 (prinfport): don't use file_name in PTAB.
4468 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
4469 * ports.c (scm_add_to_port_table): don't intialize file_name.
4470 (scm_port_file_name): remove for now.
4471 * gc.c (scm_gc_mark): don't mark PTAB file_name.
4473 * fports.h (scm_mkfile): prototype deleted.
4474 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
4476 * debug.c, unif.c: use scm_out_of_range instead of
4477 wta for range errors (ASSERT still needs work).
4479 * error.c, error.h (scm_out_of_range): new procedure.
4481 * error.c, error.h (scm_out_of_range_key): new key.
4483 * posix.c (scm_sync): #else was missing.
4485 * error.c, error.h: append _key to names scm_num_overflow and
4488 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
4489 of consing an empty list.
4490 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
4491 of macros, saves code and string space.
4492 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
4493 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
4494 lower case. Rename scm_syserror_m to scm_syserror_msg.
4495 error.h: prototypes for new procedures.
4497 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
4499 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
4501 * error.c, error.h: setup scm_num_overflow key.
4503 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
4504 Remove definition of SCM_OVSCM_FLOW.
4506 * fports.c (scm_open_file): use SCM_SYSERROR_M.
4508 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
4509 explicit message and args.
4511 * error.c, error.h, __scm.h: change system_error_sym to
4514 * error.c (system_error_sym): remove leading %% from the Scheme name
4517 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
4519 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4521 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
4522 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
4523 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
4524 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
4525 renamed. (These were introduced by unsupervised name
4528 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4530 * print.c: Added code for detection of circular references during
4531 printing. (init_ref_stack, grow_ref_stack): New functions. Added
4532 a hook for printing of closures (accessible via print options).
4533 This leads to a split of calls to scm_iprin1 into two classes:
4534 elementary print operations (e. g. the code which prints a smob)
4535 still use scm_iprin1 while top level calls (like scm_display) use
4536 scm_prin1. scm_prin1 begins by clearing the data structure used
4537 to record reference information.
4539 * print.h: Added declarations of scm_prin1 and scm_prlist.
4541 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
4543 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
4545 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
4547 * error.c (err_head): scm_iprin1 --> scm_prin1
4549 * debug.c: Adjusted header comment.
4553 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
4555 * strerror.c: Doc fix.
4557 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4559 * gdbint.c (gdb_read): Now possible to run during GC.
4560 (unmark_port, remark_port): New functions.
4562 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
4564 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
4565 of allocating a new string object. Also, increase size by
4566 the factor 2 instead of 1.5.
4568 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
4570 * __scm.h (SCM_P): Corrected to run under traditional C.
4572 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
4575 * async.c: Calls to scm_sysintern corrected.
4577 * async.h (scm_async_clock): Redundant declaration removed.
4579 * continuations.c (scm_dynthrow): Redundant declaration removed.
4581 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
4582 Definition typos corrected.
4584 * debug.h: Missing declarations of functions in debug.c added
4587 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
4588 Missing declarations to functions in eval.c added.
4590 * filesys.c: Possibly uninitialized variable rv.
4592 * gc.h (scm_object_addr, scm_unhash_name): Missing
4593 declarations of functions defined in gc.c added.
4595 * genio.c: Possible typos str_data -> wstr_data. ???
4597 * genio.c: Possibly unintended shadowing of local variable
4598 `int c' (gotos out of scope of inner `c'). ???
4600 * init.c: Uninitialized `SCM last' may be used.
4602 * ioext.h: (scm_sys_isatty_p): Typo.
4604 * list.h (scm_list_head): Missing prototype for function in
4607 * numbers.c (scm_two_doubles): Changed from extern to static
4608 (is used only within numbers.c).
4610 * numbers.h: Repeated declarations removed.
4612 * ports.h (scm_close_all_ports_except): Declaration for the
4613 function defined in ports.c added.
4615 * posix.h: Missing declarations added.
4617 * procs.h (scm_make_subr_opt): Missing declaration added.
4619 * socket.h (scm_sys_gethost): Missing declaration added.
4621 * socket.h: Redundant declarations removed (they are in fdsocket.h).
4623 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
4624 Missing declarations added.
4626 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
4628 * struct.c: Uninitialized variable `SCM answer' may be used.
4630 * unif.c (l2ra): Declaration prototype.
4632 * unif.c (scm_array_equal_p): Dummy definition removed (it is
4633 defined in ramap.c).
4635 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
4636 Redundant declarations removed (they are in ramap.h).
4638 * variable.h (scm_make_udvariable,
4639 scm_make_undefined_variable): Declaration corrected to
4640 correspond variable.c.
4642 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
4643 Missing declarations added.
4645 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
4647 * Makefile.in (distclean): Don't forget to delete fd.h.
4649 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
4651 * fd.h.in, tags.h: Trivial cleanups.
4653 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
4654 marksweep.h just declared functions from gc.c.
4655 * gc.h, libguile.h: Don't #include "marksweep.h".
4656 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4657 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
4658 dependencies updated.
4660 * libguile.h: Don't #include "files.h"; it's been deleted.
4662 * files.c (scm_sys_delete_file): Moved to filesys.c.
4663 File is now empty; deleted.
4665 * filesys.c: scm_sys_delete_file is now here. Remove
4666 #if's; they seem to rely on remnants of an old portability
4667 regimen. If the problems come up again, solve them properly,
4668 using autoconf. Specifically: Don't test M_SYSV, and #define
4669 remove to be unlink if it's #defined; don't use remove just
4670 because HAVE_STDC_HEADERS is #defined.
4671 * filesys.h: Add declarations for scm_sys_delete_file.
4672 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
4673 files.o, files.h, files.c, and files.x.
4674 * init.c: Don't #include "files.h", and don't call scm_init_files.
4676 Use SCM_P instead of PROTO; the latter intrudes on the user's
4678 * params.h: Deleted; definition of SCM_P moved to...
4679 * __scm.h: ... here, where it replaces PROTO macro.
4680 * libguile.h, smob.h: Don't #include "params.h".
4681 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
4682 smob.h: Fix prototypes accordingly.
4683 * Makefile.in: Update dependencies.
4684 (inner_h_files): Remove params.h.
4686 * gc.c: #include "gc.h"; every module should include its header,
4687 to let the compiler cross-check the declarations against the
4690 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
4691 simpos.h: #include "libguile/__scm.h".
4693 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
4695 * init.c: Don't forget to #include smob.h and init.h.
4696 * Makefile.in: Dependencies updated.
4698 * smob.h: Use PROTO instead of #if __STDC__.
4700 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
4702 * __scm.h: Doc fixes.
4704 * __scm.h, libguile.h: Use "quotes" in the #includes, not
4705 <angles>; this allows `make depends' to work properly.
4707 * libguile.h: #include smob.h and pairs.h before the others; they
4708 define typedefs used by other headers.
4710 C files should #include only the header files they need, not
4711 libguile.h (which #includes all the header files); the pointless
4712 recompilation was wasting my time.
4713 * Makefile.in (all .o dependency lists): Regenerated.
4714 * libguile.h: Don't try to get a definition for size_t here...
4715 * __scm.h: Do it here.
4716 * _scm.h: Since this is the internal libguile header, put things
4717 here that all (or a majority) of the libguile files will want.
4718 Don't #include <libguile.h> here; that generates dependencies on
4719 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
4720 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
4721 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

4807 * symbols.c: Get "symbols.h", "mbstrings.h", "alist.h",
4808 "variable.h", "eval.h", "chars.h".
4809 * tag.c: Get "tag.h", "struct.h", "chars.h".
4810 * throw.c: Get "throw.h", "continuations.h", "debug.h",
4811 "dynwind.h", "eval.h", "alist.h", "smob.h", "genio.h".
4812 * unif.c: Get "unif.h", "feature.h", "strop.h", "sequences.h",
4813 "smob.h", "genio.h", "eval.h", "chars.h".
4814 * variable.c: Get "variable.h", "smob.h", "genio.h".
4815 * vectors.c: Get "vectors.h", "eq.h".
4816 * version.c: Get "version.h".
4817 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
4818 * weaks.c: Get "weaks.h".
4820 * stackchk.h: #include "libguile/debug.h",
4822 * print.h, read.h: #include "options.h", since everyone who uses
4823 either of these files will need that.
4825 * smob.h: #include "ports.h", "genio.h", and "print.h", since
4826 anyone who uses this file will need them to define the smob
4827 printing functions. Also, get markers.h, since people will need
4828 to #define the mark functions.
4830 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
4831 * ports.h: ... to here.
4833 * ports.h (scm_port_table_size): Explicitly give type as 'int';
4834 don't rely on archaic C default type rules.
4836 * fports.h: #include "libguile/ports.h", since you need that in
4837 order to parse this.
4839 * genio.h: #include "libguile/print.h", because you need that to
4840 parse this; don't bother #including "ports.h", since print.h gets
4843 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
4845 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
4846 this; it's now a reference to an element of *scm_root.
4848 * debug.h: Don't #include "options.h"; the compiler won't be able
4849 to find that once the headers are installed; instead, #include
4850 "libguile/options.h".
4851 * gc.h: Same, with marksweep.h.
4852 * mbstrings.h: Same, with symbols.h.
4853 * scmhob.h: Same, with _scm.h.
4854 * smob.h: Same, with params.h.
4856 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
4857 C files; there's no need for this, and it forces recompilations
4860 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
4862 * error.c (scm_error): declare scm_error_callback.
4864 * error.h: prototype for scm_error_callback.
4866 * __scm.h: define lgh_error.
4867 (SCM_SYSERROR): redefine using lgh_error.
4869 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
4871 * error.c (scm_error): new procedure.
4873 * error.h: prototype for scm_error.
4875 * Makefile.in (install): install scmconfig.h from the current
4876 directory, not $(srcdir).
4878 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4880 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
4881 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
4882 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
4883 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
4884 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
4885 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
4886 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
4887 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
4888 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
4889 vports.h, weaks.h: #include "libguile/__scm.h", not
4890 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
4891 dependencies are within libguile properly.
4893 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
4895 * Makefile.in (.c.x): Simplify; there's no need to run this rule
4896 when scmconfig.h doesn't exist.
4898 * load.c (scm_sys_try_load): Correct spelling.
4900 * feature.c (scm_loc_features): Make this static.
4902 * Makefile.in (libpath.h): Omit trailing slash from path. We
4903 shouldn't require it of users, so why put it here?
4905 Move code to initialize and search %load-path from ice-9 to C
4906 code, so we can use the load-path to find the ice-9 boot code;
4907 this makes it easier to run Guile without installing it. See
4908 corresponding changes in guile/Makefile.in.
4909 * feature.c: Move stuff concerned with the load path to load.c.
4910 (scm_compiled_library_path): Deleted.
4911 Don't #include libpath.h here.
4912 * feature.h: Don't mention scm_compiled_library_path.
4913 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
4914 <sys/stat.h>, and <unistd.h> (if present).
4915 (R_OK): #define if the system hasn't deigned to.
4916 (scm_loc_load_path): New variable.
4917 (scm_init_load_path, scm_sys_search_load_path,
4918 scm_sys_try_load_path): New functions.
4919 (scm_init_load): Initialize scm_loc_load_path to point to the
4920 value cell of the Scheme %load-path variable.
4921 * load.h: Add declarations for scm_sys_search_load_path,
4922 scm_sys_try_load_path.
4923 * init.c: Call scm_init_load_path.
4924 * Makefile.in (feature.o, load.o): Dependencies updated.
4926 * load.c, load.h: Rewrite using PROTO macro.
4928 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
4930 * gc.c (scm_cellp): New function: C predicate to determine if an
4931 SCM value can be regarded as a pointer to a cell on the heap.
4933 * gc.h: Added declaration of scm_cellp.
4935 * gdb_interface.h: New file: The GDB interface header from the GDB
4938 * gdbint.c: New file: GDB interface.
4940 * gdbint.h: New file: GDB interface.
4942 * libguile.h: Added #include <libguile/gdbint.h>.
4944 * init.c (scm_boot_guile): Added scm_init_gdbint.
4946 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
4947 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
4948 found if object files and source are kept separate).
4950 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
4952 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
4954 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
4956 * configure.in: Don't substitute the values of TCL_SRC_DIR and
4957 TK_SRC_DIR; they're not relevant any more.
4959 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
4960 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
4962 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
4964 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
4965 search path, so we can find the <libguile/MUMBLE.h> headers.
4967 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
4969 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
4970 implicit in the .c.o rule.
4971 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
4974 Put the library path in a header file, instead of passing it on
4975 the command line in every compilation.
4976 * Makefile.in (libpath.h): New target.
4977 (feature.o): Depend on libpath.h.
4978 (clean): Delete libpath.h.
4979 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
4980 * feature.c: ... #include "libpath.h" here.
4981 * .cvsignore: Ignore libpath.h.
4983 Don't install the unwashed masses of Guile header files in the
4984 main #include path; put most of them in a subdirectory called
4985 'libguile'. This avoids naming conflicts between Guile header
4986 files and system header files (of which there were a few).
4987 * Makefile.in (pkgincludedir): Deleted.
4988 (innerincludedir): New variable; this and $(includedir) are enough.
4989 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
4990 (installed_h_files): Divide this up. Now this variable lists
4991 those header files which should go into $(includedir) (i.e. appear
4992 directly in the #include path), and ...
4993 (inner_h_files): ... this new variable says which files appear in
4994 a subdirectory, and are referred to as <libguile/mumble.h>.
4995 (h_files): List them both.
4996 (install): Create innerincludedir, not pkgincludedir. Put
4997 the installed_h_files and inner_h_files in their proper places.
4998 (uninstall): Corresponding changes.
4999 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
5000 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
5001 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
5002 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
5003 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
5004 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
5005 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
5006 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
5007 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
5008 vports.h, weaks.h: Find __scm.h in its new location.
5009 * __scm.h: Find scmconfig.h and tags.h in their new locations
5010 (they're both "inner" files).
5012 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
5014 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
5016 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
5018 * posix.c: Doc fixes.
5020 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
5022 * socket.c: Don't include a prototype for inet_aton; just use a
5023 K&R style declaration, to avoid warnings but minimize the chance
5024 of conflicts with the system.
5026 On NextStep, <utime.h> doesn't define struct utime, unless we
5027 #define _POSIX_SOURCE before #including it.
5028 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
5029 * acconfig.h: New comment text for above CPP symbol.
5030 * configure.in: Call it.
5031 * posix.c: #define _POSIX_SOURCE if it seems necessary.
5033 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
5035 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
5036 testing for __EMX__.
5038 * posix.c: #include <libc.h>, if it exists.
5040 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
5041 don't even know if the latter exists.
5043 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
5044 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
5045 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
5047 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
5049 (scm_init_posix): Use them when initializing the Scheme constants
5052 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
5054 * Makefile.in (libdir, includedir, bindir): Use the
5055 autoconf-supplied values, instead of deriving them ourselves.
5056 (pkgincludedir, datadir, pkgdatadir): New variables.
5057 (install, uninstall): Put the header files in a special
5058 subdirectory, not in the main search path.
5060 * Makefile.in (ALL_CFLAGS): Provide the proper value for
5061 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
5063 * Makefile.in (IMPLPATH): Deleted; never used.
5065 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
5066 on the Tcl/Tk source any more.
5067 (INCLUDE_CFLAGS): Remove references to the above.
5069 * Makefile.in (version.o): Corrected dependencies.
5071 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
5073 * libguile.h: #include "version.h"
5075 * init.c (scm_boot_guile): Call scm_init_version.
5076 * gscm.c (gscm_run_scm): Call scm_init_version.
5078 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
5079 GUILE_VERSION): AC_DEFINE these.
5080 (acconfig.h): #undef the above symbols.
5082 * Makefile.in (libobjs): Add version.o.
5083 (installed_h_files): Add version.h.
5084 (c_files): Add version.c.
5085 (gen_c_files): Add version.x.
5086 (version.o): New rule.
5087 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
5088 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

5091 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
5092 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
5093 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
5094 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
5095 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
5096 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
5097 weaks.o): Add version.h to dependency lists.
5098 (markers.o): Remove duplicate rule.
5100 * version.h: New file.
5102 * version.c: New file.
5104 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5106 * symbols.c (scm_strhash): scm_downcase is now a function, not an
5107 array; use it appropriately. Since GCC is quite happy to
5108 subscript functions, it never warned us about this; we should use
5109 -Wpointer-arith in the future. I guess we never tested
5112 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
5114 * socket.c: Doc and copyright fixes.
5116 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5118 * debug.c: Fixed and improved gdb support.
5120 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5122 * socket.c: Added declaration of inet_aton to avoid compiler
5123 warning. (Hope this solution is correct.)
5125 * stime.c: Added declaration of ftime. (This is missing in
5128 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
5130 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5132 * Makefile.in (c_files): add strerror.c.
5134 * strerror.c: new file from Emacs' sysdep.c.
5135 maybe configure should also check for sys_errlist.
5137 * configure.in (AC_REPLACE_FUNCS): add strerror.
5139 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5141 * debug.c (scm_init_debug): Added initialization for
5142 scm_evaluator_traps.
5144 * debug.h, debug.c: Various name changes.
5145 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
5146 "debug-options-interface". See commentary in options.c.
5148 * options.h, options.c: Options now have documentation strings.
5149 Also added a long explanatory commentary.
5151 * eval.c, print.h, print.c, read.h, read.c: Modifications to
5154 * gscm.c, init.c, root.c, throw.c: Bug fixes:
5155 last_debug_info_frame is now updated in all cases.
5157 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
5160 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
5162 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
5163 Added option STACK_CHECKING.
5165 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
5167 * Makefile.in: Added {debug,options,srcprop}.{h,c}
5169 * __scm.h: Removed symbols for debugging support.
5171 * acconfig.h: Added symbols for debugging support.
5173 * configure.in: Added user option for debugging support.
5174 --enable-debug will include the debugging code into libguile.a.
5176 * continuations.c (scm_make_cont): Enlarged the #if 0 around
5177 scm_relocate_chunk_to_heap.
5179 * debug.c: New file: low-level debugging support. It also
5180 includes support for debugging with gdb. (The extensions to gdb
5181 are written by Per Bothner at Cygnus.)
5183 * debug.h: New file: low-level debugging support.
5185 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
5186 argument pairs. Extensive modifications to the debugging
5187 evaluator. Added "SECTION:" commentaries to clarify what happens
5188 when, during double compilation. Renamed EVALIMP --> EVALIM.
5189 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
5190 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
5191 the beginning of the file. New procedure: scm_unmemocopy.
5192 Added some global state variables needed by the debugging
5193 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
5194 check_entry, check_apply, check_exit, debug_options and
5195 evaluator_traps. New acro: undefine.
5197 * eval.h: Renamed EVAL --> XEVAL.
5199 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
5200 --> scm_make_weak_key_hash_table.
5202 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
5203 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
5205 * libguile.h: Conditionally include debug.h
5207 * objprop.c (scm_object_properties, scm_set_object_properties_x):
5208 scm_object_properties shouldn't return handle. `handle' now gets
5209 initialized in scm_set_object_properties_x. scm_object_properties
5210 doesn't any longer create an entry in scm_object_whash.
5212 * options.c: New file: handling of run time options.
5214 * options.h: New file: handling of run time options.
5216 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
5218 * print.c: New procedure: scm_print_options
5220 * print.h: Defines for print options.
5222 * read.c: New procedure: scm_read_options
5224 * read.h: Defines for reader options.
5226 * root.h: Added scm_source_whash among scm_sys_protects.
5228 * srcprop.c: New file: source properties.
5230 * srcprop.h: New file: source properties.
5232 * throw.c (jbsmob): Jump buffers are now correctly allocated.
5233 (Bug found by A. Green.)
5235 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5237 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
5239 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
5241 * libguile.h: #include "objprop.h"; I guess this was forgotten.
5243 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
5244 and should be called by the final client.
5246 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
5248 * gc.h: Use the PROTO macro when declaring functions.
5249 * gc.c: Use the PROTO macro when declaring static functions.
5250 Remove the CPP hair around function definitions.
5252 * gc.c (scm_init_storage): Initialize scm_asyncs.
5254 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
5255 preprocessor symbol; "__scm.h" is where it might get #defined.
5256 * __scm.h: Similar: #include <scmconfig.h> before testing
5259 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
5261 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
5263 * init.c (scm_boot_guile): Add init_func argument; call
5264 (*init_func) instead of calling scm_appinit; it's ucky to
5265 hard-code names for the user's procedures.
5266 * init.h (scm_boot_guile): Adjust declaration.
5268 * __scm.h (PROTO): New macro, for declaring functions with
5271 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
5272 eliminate all the __STDC__ conditionals.
5273 (scm_boot_guile): Add declaration.
5274 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
5275 Remove __STDC__ conditionals around function definitions; the
5276 declarations in init.h will provide the same information, more
5279 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
5280 complain about it in the error message; the error message is
5281 adequate without that note, and there's nothing the user can do
5284 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
5286 * Makefile.in (ancillary): Drop def.sed.
5288 * posix.c (scm_init_posix): Use numeric values, rather than
5289 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
5290 F_OK. The symbols aren't available on some systems, and I'm
5291 pretty sure their values are fixed by common widespread practice.
5292 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
5294 More functions unavailable on some systems.
5295 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
5296 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
5298 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
5299 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
5300 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
5301 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
5302 stub that signals an error as the #else.
5304 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
5306 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>

5344 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
5345 from scm_sizet to int.
5347 * error.c: include unistd.h.
5349 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
5352 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
5354 * __scm.hd, def.sed: deleted.
5356 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
5358 Changes for NeXT, suggested by Robert Brown.
5359 * configure.in: Call AC_TYPE_MODE_T.

5361 NeXT. Put header file list in alphabetical order.
5362 * configure, scmconfig.h.in: Regenerated.
5363 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.

5387 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
5389 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
5391 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
5393 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
5395 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
5396 This is necessary on Ultrix, and doesn't hurt portability.
5398 * Makefile.in (dist-dir): New target, implementing a new dist system.
5399 (installed_h_files): Put in alphabetical order.
5400 Remove duplicate entries for markers.h and unif.h.
5401 (c_files): Remove duplicate entries for markers.c.
5402 (ancillary): Renamed from anillery; all uses changed. Remove
5403 PLUGIN; it's a directory, and needs special treatment in dist-dir.
5404 Remove all the ../doc/* files; doc/Makefile.in handles that.
5406 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
5408 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
5409 every if must have an else, or else the whole command has a
5410 non-zero exit code whenever the if's condition is false.
5412 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
5414 * posix.c: include string.h.

5421 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
5422 Remove leading % from scheme names.
5423 Do not return error values, call SCM_SYSERROR or similar.

5472 Initialization specific to tcl interpreters removed.
5474 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
5476 * ports.c (scm_ports_prehistory): size malloced here doesn't
5477 matter so long as it is non-0 (got rid of "* 4").
5479 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
5481 * gscm.h: gscm_mkarray eliminated (presumably was not being used
5482 since its definition was bogus).
5484 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
5486 * mallocs.[ch]: back again (for rx at least).
5488 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
5490 * ports.c: removed functions relating to the mapping between ports
5491 and descriptors. (That stuff is unix-specific and should be collected
5492 in a separate library).
5494 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
5495 (Tom Mckay@avanticorp.com)

5499 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
5500 handled correctly (SCM_FREEP was applied to them) -- test for
5501 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

5546 (possibly triggering gc) before setting the tag of the corresponding
5549 * pairs.c (scm_delq_x): never throw an error.
5551 * vectors.c (scm_make_vector): made the default vector fill argument
5552 into '() (much more useful than the previous value, "#unspecified")

5556 * ports.c (scm_add_to_port_table): Added fields
5557 to port table entries: file_name, line_num, col.
5558 Update these in open_file, gen_getc and gen_ungetc.
5559 Added procedures to access those fields.
5561 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>

5669 initialization to fix a race condition.
5671 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

5695 set the multi_byte flag correctly in symbols. This is wrong.
5696 intern_obbary_soft and msymbolize should take an extra parameter.
5697 Also, weird multibyte symbols don't print correctly.
5698 The weird symbol syntax is also a bit bogus (emacs doesn't quite
5701 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
5703 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means

5706 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
5708 * strings.c (scm_make_shared_substring): build'em.
5709 It might better to keep a table of these and use one
