1 1999-09-11 Jim Blandy <jimb@savonarola.red-bean.com>
3 * Makefile.am (CLEANFILES): Remove versiondat.h; that should only
4 be removed by `make distclean', since it's generated by configure.
5 * Makefile.in: Regenerated.
6 (Thanks to Robert Bihlmeyer.)
8 * strop.c (scm_substring_move_x): Signal an error if start1
9 doesn't come before end1. (Thanks to Karoly Lorentey).
11 * numbers.c (scm_istr2flo): Don't call SCM_INEXP without first
12 calling SCM_NIMP. (Thanks to Karoly Lorentey).
14 * version.c (scm_libguile_config_stamp): Deleted. See
15 corresponding change to ../ice-9/boot-9.scm.
16 * versiondat.h.in: Remove definition for GUILE_STAMP.
17 * version.h: Delete prototype.
18 * Makefile.in: Regenerated.
20 1999-09-11 Gary Houston <ghouston@easynet.co.uk>
22 * filesys.c (scm_directory_p): new procedure "directory?" Returns
23 a boolean indicating whether its argument is a directory
24 port as returned by opendir (thanks to Dirk Herrmann for the
27 1999-09-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
29 * backtrace.c (display_frame_expr): Don't print a newline.
30 (display_frame): Print the newline here instead.
31 (display_backtrace_body): Don't print "Backtrace:".
32 (scm_backtrace): Print "Backtrace:" here instead.
34 1999-09-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
36 * procs.c (scm_setter): Signal WTA if handed an entity or operator
39 * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
40 primitives. (Thanks to Greg Badros);
41 (scm_hook_to_list): New primitive; Hooks are now smobs.
43 1999-09-08 Gary Houston <ghouston@easynet.co.uk>
45 * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value
46 of #f for the 10th vector element to avoid an exception
47 seen by Bernard Urban.
48 (scm_mktime): unneeded ASSERT removed.
50 1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
52 * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
55 * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
57 1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
59 * numbers.c: Converted comparison operations to dispatch on
60 generic if args don't match.
62 * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
64 1999-09-06 James Blandy <jimb@mule.m17n.org>
66 * guile-snarf.c: Deleted. Snarfing should respect CPP
67 conditionals, so it needs to actually run CPP. Bleah.
69 1999-09-05 James Blandy <jimb@mule.m17n.org>
71 Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
72 * guile-snarf.in: Be sure to exit with an error if CPP does.
73 * Makefile.am (.c.x): Delete the .x file and exit with an error
74 status if guile-snarf exits with an error status.
75 * Makefile.in: Regenerated.
77 * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
78 scm_makekey, which doesn't exist any more. Guess nobody's using
81 * guile-snarf.c: New implementation of guile-snarf, meant to be
82 more robust than the shell script. I think it's complete, but I
83 haven't tested it at all, and I haven't changed the build process
84 to actually use it. We should compare its output against that of
85 the existing shell script, for all source files.
87 * guile-snarf.c (parse_args): Abort if we haven't handled some
90 1999-09-03 James Blandy <jimb@mule.m17n.org>
92 * load.c (scm_search_path): If the filename has any extension at
93 all, ignore the entire list of extensions. Also, don't check whether
94 the file is accessible. If the file exists, accessible or not, we
95 should return it. Inaccessible files should cause an error later.
96 (Thanks to Keisuke Nishida for the suggestions.)
98 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
100 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
101 atexit not available. (sunos4.1.4 needs it.)
103 1999-09-01 James Blandy <jimb@mule.m17n.org>
105 I take it all back --- bcopy does handle overlapping source and
106 destination areas correctly. At least on every system I could
107 find. But it is better to use AC_REPLACE_FUNCS than to introduce
108 new CPP conditionals.
109 * memmove.c: New file, implementing memmove in terms of bcopy.
110 * scmconfig.h.in: Regenerated.
112 Allocators should use the `void *' type for generic pointers.
113 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
114 argument and return types.
115 * gc.h: Corresponding changes to prototypes.
118 1999-08-31 James Blandy <jimb@mule.m17n.org>
120 * numbers.c (scm_init_numbers): Claim to support the `complex'
121 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
123 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
124 find (ice-9 boot-9) when Guile was compiled in a separate
125 directory from the source. (Thanks to Rodney Brown.)
126 * Makefile.in: Regenerated.
128 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
129 table lengths by the size of a single element when growing the
130 table. (Thanks to Bill Schottstaedt.)
132 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
134 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
135 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
136 since that cuts down the time for type dispatch by 50%.
138 1999-08-30 James Blandy <jimb@mule.m17n.org>
140 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
141 not a correct substitute for memmove, because it doesn't handle
142 overlapping source and destination areas on many platforms.
143 Overlaps are the primary reason to use memmove in the first place.
144 * ports.c (scm_ungetc): Same.
145 * strop.c (scm_substring_move_x): Same.
147 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
149 * gc.c (scm_init_storage): Skip registration of cleanup on systems
150 which lack atexit. (Is it important that cleanup is made
151 properly? Maybe we should replace all `exit' with `scm_exit' and
154 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
155 scm_struct_free_standard, scm_struct_free_entity): Declared to
156 return scm_sizet instead of size_t.
158 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
159 there on sunos4.1.4.)
161 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
163 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
164 Account for the case when second argument is unbound.
166 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
167 (Thanks to Karoly Lorentey.)
169 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
170 isn't present. (Thanks to Suzuki Toshiya.)
172 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
175 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
178 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
179 Bernard Urban and Ian Grant.)
181 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
182 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
183 change in the representation of entities and operators.)
185 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
187 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
188 don't allocate zero bytes (thanks to Bill Schottstaedt).
190 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
192 * procs.c (scm_setter): Converted to use generic dispatch.
194 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
197 * load.c (scm_search_path): Don't try extensions which already are
198 present at the end of the filename.
199 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
201 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
203 Cleanup and simplification of generic method dispatch.
204 Also, the quadruple representation of entity and operator
205 procedures has been replaced with single.
207 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
209 * print.c (scm_isymnames): Removed #@hash-dispatch.
211 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
212 from eval.c; Support 0 arity methods.
213 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
214 (scm_apply_generic_env): Removed.
215 Replaced slots proc0-3 with procedure.
217 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
218 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
219 SCM_OPERATOR_PROCEDURE.
220 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
221 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
223 * struct.c, struct.h: Replace 4 procedure slots with one.
224 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
226 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
229 * eval.c (scm_sym_args): Removed.
230 (SCM_CEVAL): Simplified entity application.
231 Moved dispatch code to objects.c.
233 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
235 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
237 * sort.c (closureless): Use scm_eval_body.
239 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
240 with a symbol as last form was first called normally and then via
241 `map' or some other mechanism using primitive apply, an ILOC was
244 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
246 This change extends the representation of primitive procedures
247 with more data fields, e.g. a place for documentation and true
248 procedure properties.
250 * procs.c, procs.h (scm_subr_entry): New type: Stores data
251 associated with subrs.
252 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
253 SCM_SUBR_DOC): New macros.
254 (scm_subr_table): New variable.
255 (scm_mark_subr_table): New function.
257 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
259 * gc.c (scm_gc_mark): Don't mark subr names here.
260 (scm_igc): Call scm_mark_subr_table.
263 This change implements a scheme for letting a generic work as a
264 shadow for a primitive procedure. If the primitive procedure
265 can't dispatch on its arguments, control is left over to the
266 generic. Normal wrong type arg errors will be generated until the
267 user has hung the first method on the primitive.
269 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
271 * procs.c, procs.h (scm_subr_p): New function (used internally).
273 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
275 * objects.c, objects.h (scm_primitive_generic): New class.
277 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
279 * print.c (scm_iprin1): Print primitive-generics.
281 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
282 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
284 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
285 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
286 primitives). NOTE: This means that it is now *required* to use
287 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
288 obscured representation that will be removed in the future anyway,
289 so backward compatibility is no problem here).
291 * numbers.c: Converted most numeric primitives (all but bit
292 comparison operations and bit operations) to dispatch on generic
296 Better support for applying generic functions.
298 * eval.c, eval.h (scm_eval_body): New function.
300 * objects.c (scm_call_generic_0, scm_call_generic_1,
301 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
305 Optimization of the generic function dispatch mechanism.
307 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
308 called scm_memoize_method instead of doing a second lookup.
310 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
315 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
316 scm_sysintern so that the binding connected with the subr name
317 isn't cleared when we give set = 0.
320 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
322 More transparent handling of ports with print states.
324 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
325 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
326 instead of a pair of a port and a print state. We'll need to cons
327 once extra in scm_printer_apply but the type system will be
328 cleaner, it will mix better with GOOPS, and, it will be even more
329 transparent to the user.
331 * print.c (scm_get_print_state): New procedure: Given an output
332 port, return the print state associated to it in the current print
333 chain, if one exists;
334 (scm_port_with_print_state): New procedure: Associate a
335 print-state with a port.
336 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
337 (scm_printer_apply): Wrap port and pstate as a smob;
338 (print_state_printer): Removed.
340 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
342 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
345 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
346 testing (otherwise the port-print-state trick won't be transparent
347 to the user; one example where this caused problems was in the
348 (ice-9 format) module).
350 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
352 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
353 SCM_UNSPECIFIED instead of the set value.
355 1999-08-20 James Blandy <jimb@mule.m17n.org>
357 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
359 * ports.h (enum scm_port_rw_active): New enum, containing
360 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
361 zero). The debugger knows about enums, but doesn't know about
363 (typedef scm_port): Declare rw_active member to be an enum
365 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
367 * ports.c (scm_add_to_port_table): Same.
368 * strports.c (st_flush, st_end_input): Same.
370 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
371 scm_must_realloc, and scm_done_malloc as appropriate.
373 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
375 * sort.c (quicksort): Added condition to protect the algorithm
376 from crashing the interpreter if the less predicate is buggy.
378 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
380 * fports.c (fport_write): fix line-buffering mode again.
381 (scm_open_file): recognise 'l' for line-buffering.
382 (scm_setvbuf): recognise _IOLBF for line-buffering.
384 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
386 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
389 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
392 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
394 * fports.c (fport_write): use memcpy instead of strncpy, in case
395 the data contains NUL.
397 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
399 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
401 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
402 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
403 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
404 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
405 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
406 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
407 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
408 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
409 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
410 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
411 scm_sym_ as prefix for symbols.
413 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
415 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
416 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
417 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
418 scm_sym_atcall_cc): Made global.
420 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
422 * eval.c (scm_sym_args): Made global.
424 * objects.c (scm_set_object_procedure_x): Disallow setting of
425 procedures for pure generic functions.
427 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
429 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
430 Scheme name from lseek to seek, but lseek was added recently so
431 it shouldn't be a big problem.
432 * ports.c, gdbint.c, ioext.c: changed callers.
434 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
436 * fports.c (fport_input_waiting): if select is used, return 1
437 instead of whatever FD_ISSET expands to. maybe it will be useful
438 to interpret the value from the input_waiting ptob procedure as a
439 lower bound on the number of bytes available.
441 * Mikael asked for a few names to be changed...
443 * ports.c (scm_make_port_type): take the write procedure as the
444 second argument instead of the flush procedure.
445 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
446 fflush -> flush, read_flush -> end_input, fclose -> close,
447 fill_buffer -> fill_input, ftruncate -> truncate,
448 input_waiting_p -> input_waiting.
450 * ports.c (end_input_void_port): was read_flush_void_port.
451 (scm_set_port_end_input): was scm_set_port_flush_input.
452 (scm_set_port_flush): was scm_set_port_write.
453 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
454 (scm_end_input): was scm_read_flush.
455 (scm_fill_input): was scm_fill_buffer.
456 (scm_flush): was scm_fflush.
457 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
458 (fport_end_input): was local_read_flush.
459 (fport_flush): was local_fflush.
460 (fport_close): was local_fclose.
461 (fport_truncate): was local_ftruncate.
462 (fport_seek): was local_seek.
463 (fport_free): was local_free.
464 (fport_fill_input): was fport_fill_buffer.
465 * strports.c (st_end_input): was st_read_flush.
466 (st_truncate): was st_ftruncate.
467 * vports.c: (sf_flush): was sfflush.
468 (sf_close): was sfclose.
469 (sf_fill_input): was sf_fill_buffer.
471 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
474 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
476 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
477 forms now contain the expressions to be dispatched upon instead of
478 depending on a surrounding lambda or let; Generic function
479 dispatch has been optimized; `apply' on a generic function now
480 works a little bit strangely. It uses a trick so that the type
481 dispatch code in SCM_CEVAL can be reused.
483 * objects.h, objects.c (scm_apply_generic_env): Added (used by
485 (scm_operator_p): Added.
486 (scm_sym_atdispatch): Added.
487 (scm_set_object_procedure_x): Modified to handle the new style
489 (scm_object_procedures): New debugging procedure.
491 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
493 * eval.c, eval.h (scm_sym_args): Added.
495 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
497 * feature.c, feature.h (scm_c_run_hook): Added.
499 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
500 cdrxnoap and loopnoap instead of begin and loop.
502 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
504 * ports.c (scm_putc, scm_puts),
505 * unif.c (scm_uniform_array_write): use scm_lfwrite.
506 * ports.c (scm_putc): change type of first argument from int to char.
508 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
510 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
511 SCM_IM_HASH_DISPATCH.
513 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
514 (scm_si_redfined, scm_si_hashsets): Moved.
516 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
517 flag which combines type and status info so that the class
518 redefinition protocol has zero cost during normal execution.
520 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
522 * ports.h (scm_ptob_descriptor): include a write procedure again.
523 it's more efficient for unbuffered fports (e.g., sockets.)
525 * ports.c (scm_puts): use ptob->write.
526 * vports.c (scm_make_sfptob): set write proc in ptob.
527 * strports.c (scm_make_stptob): set write proc in ptob.
528 * ports.c (write_void_port): new procedure.
529 * vports.c (sf_write): new procedure.

546 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
547 code, particularly an unnecessary test (len != size, where len ==
548 size). (Was this leftovers from debugging code, or have I missed
551 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
552 size. (Thanks to James Dean Palmer.)
554 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
555 (Thanks to Lorentey Karoly.)
557 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
559 * eval.c (scm_m_expand_body): Use scm_cons_source.
561 * struct.c (scm_print_struct): Use vtable name.
563 * print.c (scm_init_print): Set name of print state type.
565 * stacks.c (scm_init_stacks): Set name of stack type.
567 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
569 * eval.c (SCM_CEVAL): Removed old implementation of internal
572 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
574 * debug.c, debug.h (scm_reverse_lookup): Added.
575 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
576 internal procedure definitions; Don't use scm_i_inner_name.
578 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
581 * eval.h: Added prototypes for multi language support functions.
583 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
584 improper lists in the low-level representation, since that will
585 cause a begin to be prepended at macro expansion.
587 * eval.c (scm_cons_source): Version of cons which copies source
588 properties from an existing cell.
589 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
591 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
592 procedure source before calling scm_unmemocopy instead of faking
595 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
597 Ported `internal defines' fix from SCM. Original ChangeLog entry:
599 1998-07-09 Radey Shouman <radey@colorage.com>
601 * eval.c (ceval_1): Modifications to allow rewriting of interal
602 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
603 body of which it is the CAR is macro expanded by m_expand_body,
604 which rewrites internal DEFINE.
606 (m_expand_body): Added.
608 (m_macroexp1): Added argument to control error checking:
609 m_expand_body may speculatively expand forms in the wrong
610 environments. Made argument number checks conditional on
613 (m_body): Added, error checks bodies and inserts the ISYM tokens.
615 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
618 (m_cond): (m_case): (m_quote): Modified to avoid destructively
619 changing their argument forms. Since m_expand_body
620 speculatively macro expands forms the process must be
623 (m_ident_eqp): Fixed to use proper environment.
625 (renamed_ident): Added DEFER_INTS_EGC.
627 Added prototypes for static functions.
633 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
634 is false, do not produce an error for unbound variables, return a
635 pointer to cell_undef instead.
637 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
641 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
642 destructively changing their argument forms. Since m_expand_body
643 speculatively macro expands forms the process must be reversible.
645 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
646 SCM_IM_LET introduced by named lets.
648 (scm_m_letstar): Use scm_m_body instead of bodycheck.
650 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
651 scm_letrec. scm_letrec1 does not check for a null binding and
652 takes an additional argument to specify the ISYM of the body. Use
653 scm_m_body instead of bodycheck.
655 (scm_m_let): Use scm_m_body instead of bodycheck.
657 (scm_m_expand_body, scm_macroexp): New.
659 (unmemocopy): Account for ISYMs introduced by scm_m_body.
661 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
662 check=1. Throw error for internal defined that have not been
663 rewritten by scm_m_expand_body.
665 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
666 Removed prototype for SCM_APPLY.
668 * tags.h: Added extern declaration of scm_isymnames.
670 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
672 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
674 * lang.c: New file: Beginning of multi-language support.
676 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
678 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
679 (scm_dynamic_wind): Added argument checking for the after guard so
680 that we don't add garbage on the dynwind chain.
681 (scm_swap_bindings): Added.
683 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
684 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
685 (scm_isymnames): New isyms for multi-language support.
687 * eval.c (scm_nil, scm_t): New symbols.
688 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
689 forms for multi-language support.
691 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
693 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
695 Renamed functions in the random function library interface
696 from scm_i_XXX --> scm_c_XXX.
698 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
700 * ports.c (scm_putc): fix line-buffering.
702 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
704 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
705 scm_set_ptob_XXX --> scm_set_port_XXX.
707 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
709 * ports.c, ports.h (scm_make_port_type): New interface for
710 creation of port types (replaces scm_newptob). Just as for the
711 smobs, we need to separate the internal representation of smob
712 types from the interface, so that we easily can add new fields and
713 rearrange things without caring about backward compatibility.
714 This change was forced by the need in GOOPS to create classes
715 representing port types.
716 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
717 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
718 scm_set_ptob_seek, scm_set_ptob_truncate,
719 scm_set_ptob_input_waiting_p): New setters.
720 (scm_newptob): Rewritten to use scm_make_port_type. For backward
722 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
723 (scm_prinport): Removed.
724 (scm_port_print): Added.
725 (scm_print_port_mode): Added.
726 (void_port_ptob, print_void_port, close_void_port, noop0):
727 Removed. Removed #include "genio.h" Added #include "objects.h",
730 * fports.c (prinfport): Moved code from ports.c.
732 (scm_fptob): Removed. Instead use new interface.
733 (scm_make_fptob): Added. (Need to create basic ports in a
734 specific order in ports.c.)
736 * strports.c (scm_stptob, prinstpt, noop0): Removed
737 (scm_make_stptob): Added.
739 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
740 (scm_make_sfport): Added.
742 * filesys.c (scm_dir_print): Don't use the port printing code.
743 Instead provide specific directory printer.
745 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
747 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
750 * smob.c (scm_smob_print): Handle non-existing type name nicely.
751 Removed #include "genio.h"
753 * objects.c (scm_make_port_classes): New function ptr.
755 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
757 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
759 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
760 allow the 1st argument to be a fdes or filename as well as a
761 port (as in the filesys.c version).
763 * filesys.c (scm_truncate_file): removed.
765 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
767 * readline.c, readline.h: Removed.
769 * objects.c, objects.h (scm_port_class): Added.
770 (scm_class_of): Look up port class in scm_port_class.
771 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
772 SCM_INOUT_PCLASS_INDEX): Added.
775 * Makefile.am: Removed genio.c, genio.x.
779 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
781 * init.c: Make sure that scm_post_boot_init_modules is called only
782 once. (Important when using a dumped image.; Thanks to Bernard
785 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
787 * guardians.c (scm_guardian_zombify): Separate scanning for
788 zombies from marking the pairs of the free list.
790 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
791 use the macros. (Thanks to Michael Livshin.)
793 * eval.c (scm_m_lambda): Let bodycheck check the body of the
794 lambda. Let your sins be purified by the blood of the lambda.
795 (Thanks to Eric Hanchrow.)
797 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
798 (Thanks to Valdis Kletnieks.)
800 Fixes for EMX from Mikael Ståldal.
802 * filesys.c: #include <io.h>, if we have it.
803 * scmconfig.h.in: Regenerated.
805 * stime.c (ftime): Delete declaration for this function --- let
806 the system supply it.
808 Cleanups from John Bley.
810 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
812 * gsubr.c: Don't include "gsubr.h" twice.
814 Cleanups for compilation on Irix 6, from David Kaelbling.
816 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
817 regex_t pointer. This is what the callers have, mostly.
818 (scm_regexp_exec): Don't forget to pass the `rx' argument to
819 scm_regexp_error_msg.
821 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
822 int. That way, if we get a warning on this line, it's more likely
823 that we're really missing bits we care about.
825 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
828 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
829 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
830 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
831 cast at all is more appropriate in every case. At the moment, we
832 assume everywhere that SCM is an integral type anyway.
834 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
836 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
837 read_pos after scm_fill_buffer.
839 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
842 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
843 fports.c (fport_fill_buffer): implement the interface change.
845 * ports.c (scm_fill_buffer): interface change: no longer increments
846 read_pos past the character that's returned. it seems clearer to
847 leave it to the caller to decide what to do (thanks Jim).
849 * vports.c (sf_fill_buffer): put the read char into the buffer
850 as well as returning it.
852 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure

857 * strports.c (scm_strprint_obj): simplify. start with initial
859 (st_seek): don't allow string to be extended if seeking past
860 the end of a read-only port.
862 1999-07-12 Gary Houston <ghouston@easynet.co.uk>
864 * strports.c (st_seek): change the resize checks.
866 * ports.c (scm_ftruncate): throw error if offset works out negative.
868 * strports.c (st_flush): increase string size in blocks of
869 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
870 it's greater and reset read_buf_size.
871 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
872 to be maintained for output ports too (it holds the written
873 part of the string, while write_buf may have unwritten buffer
875 (st_truncate): rewritten.
876 (top of file): added a few notes.
878 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
880 Patch from Greg Badros:
881 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
882 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
883 (function pointer) argument to scm_make_gsubr and scm_make_subr
884 calls. This avoids warnings in C++ programs using guile-snarf.
886 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
888 * strports.c (st_grow_port): set pt->read_pos. set
889 pt->read_buf_size one less than pt->write_buf_size if there's
890 an unwritten char at the end of the string. similarly for
892 (st_resize_port): renamed from st_grow_port.
893 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
894 seek from read_end instead of write_end for SEEK_END.
895 (st_ftruncate): calculate current length using readbuf, not write
897 (scm_strport_to_string): use read_buf_size for length.

903 (scm_call_with_output_string, scm_strprint_obj): use
904 scm_strport_to_string.

907 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
909 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)

915 and "bigneg" smob types.
917 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
918 SCM_RETURN_NEWSMOB macro. Added protos for new functions in

1006 * dynl-dl.c (sysdep_dynl_link): Added parenthesis around the
1007 trinary conditional in order for the flag computation to be
1010 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1012 * struct.c, struct.h:
1014 In order to support different kinds of deallocation, a destructor
1015 slot has been added to struct vtables. This allows for structs
1016 containing pointers to other memory blocks.
1018 (scm_struct_i_free): New hidden struct slot. Holds destructor for

1087 1999-06-19 Jim Blandy <jimb@savonarola.red-bean.com>
1089 Patch from Greg Harvey:
1090 * eq.c, eval.c, list.c, ramap.c, vectors.c: Always write parens
1091 around the condition of an `if', `while', etc., even if the
1092 condition is a macro invocation that expands to something
1093 surrounded by parens. It's more readable.
1095 * eval.c (scm_map, scm_for_each): Verify that all arguments are
1096 proper lists, and of the appropriate lengths.
1097 (check_map_args): New function. (Thanks to Greg Harvey for the
1100 1999-06-19 Michael Livshin <mike@olan.com>
1102 * guardians.c (guardian_t): `next' - new field to be used for
1103 chaining the live guardians in a single-linked list during the GC
1105 (GUARDIAN_NEXT): convenience macro to access the `next' field.
1106 (guardians, guardians_size, n_guardians): deleted.
1107 (first_live_guardian, current_link_field): new globals used to
1108 point to the head of the live guardian list and current `next'
1109 field, respectively.
1110 (g_mark): append the guardian to the live guardian list.
1111 (scm_guardian_gc_init): zero the live guardian list.
1112 (scm_guardian_zombify): iterate through the live guardian list.
1114 (Applied by Jim Blandy.)
1116 1999-06-16 Jim Blandy <jimb@savonarola.red-bean.com>
1118 * gc.c (scm_mallocated): Just make this signed.
1119 (scm_igc): Check for underflow by seeing if this is negative.
1121 * gc.h (scm_mallocated): Fix declaration.
1122 (Thanks to Greg Harvey.)
1124 * ports.h: #include <sys/types.h>, to get a definition for `off_t'.

1128 * stime.c (bdtime2c): Initialize lt->gmtoff and lt->tm_zone from
1129 sbd_time. (Thanks to Eric Hanchrow.)
1131 Fix from Ken Raeburn <raeburn@raeburn.org>:
1132 * weaks.c (scm_make_weak_vector): Add another extra slot before
1133 vector contents, to be used only during garbage collection.
1134 * weaks.h (SCM_WVECT_GC_CHAIN): New macro to access it.
1135 * gc.c (scm_weak_vectors): Now a SCM instead of a SCM*, and now
1137 (scm_weak_size, scm_n_weak): Deleted.
1138 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
1139 vectors without allocating new storage during GC, using
1140 scm_weak_vectors as the head of the chain.
1141 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1142 instead of stepping through an array.
1143 (scm_gc_sweep): Update offset used to find start of weak vector to
1145 (scm_init_storage): Set scm_weak_vectors to EOL.
1147 Fix from Ken Raeburn <raeburn@raeburn.org>:
1148 * gc.c (already_in_gc): New variable.
1149 (scm_igc): Set and clear already_in_gc; abort if it's set at
1152 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
1154 Fix from Gary Houston:
1155 * fports.c (local_seek): Signal an error if the seek fails.
1156 * ports.c (scm_lseek): Don't check return value of port's seek
1157 function; it's its job to signal an error if there's a problem.
1159 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>
1161 * strports.c (scm_call_with_output_string): Don't include the
1162 extra character at the end of the string in the result.
1164 * ioext.c (scm_read_line): Switch to reading properly.
1166 * fports.c, fports.h, gc.c, gdbint.c, ioext.c, ports.c, ports.h,
1167 scmsigs.c, strports.c, vports.c: Install the sources which
1168 actually correspond to the changes described below. I got the
1169 ChangeLog entries and the patch from two different places...
1171 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1173 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1174 it shows up as terrible performance, as we GC constantly.
1176 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
1177 newline. A bit faster, and definitely hairier.
1178 (scm_read_line): Count newlines here instead.
1180 * strings.c (scm_take_str): New function.
1181 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
1182 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use
1183 scm_take_str, to avoid copying the string.
1185 Add some simple-minded support for line buffered ports.
1186 * ports.h (SCM_BUFLINE): New flag for ports.
1187 * init.c (scm_init_standard_ports): Request line-buffering on
1188 the standard output port.
1189 * ports.c (scm_mode_bits): Recognize 'l' as a request for line
1191 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1192 and there's a newline to be written, flush the port.
1194 Gary Houston's open-buffer port patches:
1196 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1198 * ports.c: (scm_lseek): clear buffers even if just reading current
1201 * fports.c (local_fclose): call local_fflush unconditionally.

1207 strports.c: take care of rw_active and rw_randow.
1208 fports.c: scm_fport_drain_input: removed. do it all in ports.c.
1209 strports.c (scm_mkstrport): check that pos is reasonable.
1210 ioext.c (scm_ftell, scm_fseek): use lseek.
1211 (SCM_CLEAR_BUFFERS): macro deleted.

1213 ports.h (scm_ptobfuns): add ftruncate.
1214 ports.c (scm_newptob): set ftruncate.
1216 ports.c (scm_ftruncate): new procedure.
1217 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.
1218 strports.c (st_seek, st_grow_port): new procs.
1219 fports.h (scm_port): change size types from int to off_t.
1220 ports.c (scm_init_ports): initialise the seek symbols here
1221 instead of in ioext.c.
1222 strports.c (scm_call_with_output_string): start with an empty
1223 string, so seek and ftruncate can be used.
1225 gdbint.c: adjust string port usage.
1227 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1229 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
1230 equivalent to fflush for the read buffer.
1231 * ports.c (scm_newptob): set read_flush.
1232 ports.c (void_port_ptob): set read_flush.
1233 fports.c (local_read_flush): new proc. add to ptob.
1234 strport.c (st_read_flush): likewise.
1235 vport.c (sf_read_flush): likewise.
1236 fports.h (struct scm_fport): remove random member. there's nothing
1237 left but fdes. leaving it as a struct to allow for future changes.
1238 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1239 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1240 ptob proc if the read buffer is filled.
1242 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1244 * ports.h (scm_port): add a rw_random member and replace
1245 reading and writing members with rw_active member.
1246 SCM_PORT_READ/SCM_PORT_WRITE: new values.
1248 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
1250 * ports.h (struct scm_port_table): add writing and reading members
1251 to replace write_needs_seek: it isn't good enough for non-fports.
1252 ports.c, ioext.c, fports.c: corresponding changes.
1253 (struct scm_port_table): give it a typedef and rename to scm_port.
1254 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
1255 corresponding changes.
1257 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
1259 * ports.c (scm_newptob): bugfix: set seek member.
1260 * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
1261 and generalised to all port types.
1263 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
1265 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
1266 signals (it was only being done for handlers installed from Scheme).
1267 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
1268 waiting for input caused an EINTR error from read.
1270 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
1272 * ports.h (struct scm_port_table): make all the char members
1273 unsigned, so they convert to int without becoming negative if large.
1275 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
1277 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
1278 with threads enabled. rename this procedure to
1279 fport_wait_for_input and take a port instead of a fdes.
1280 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
1282 * readline.c (scm_readline): Applied a patch from Greg Harvey to
1283 get readline support working again: use fdopen to get FILE objects.
1285 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
1287 * gc.c (scm_init_storage): install an atexit proc to flush the
1289 (cleanup): the new proc. it sets a global variable which can be
1290 checked by the ptob flush procs to avoid trying to throw
1291 exceptions during exit. not very pleasant but it seems more reliable.
1292 * fports.c (local_fflush): check terminating variable and if set
1293 don't throw exception.
1294 * CHECKME: that the atexit proc is installed if unexec used.
1296 * throw.c (scm_handle_by_message): don't flush all ports here.
1297 it still causes bus errors.
1299 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
1300 and move to ioext.c.
1302 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
1304 * ports.c (scm_char_ready_p): check the port buffer and call the
1305 ptob entry if needed.
1307 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
1308 ptob initialisers. use it in char-ready
1310 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
1312 * vports.c (sfflush): modified to write a char (since softports
1313 currently use shortbuf.)
1315 * fports.c (scm_standard_stream_to_port): moved to init.c and
1318 * init.c (scm_init_standard_ports): make stdout and stderr
1319 unbuffered if connected to a terminal. with stdio they
1320 were line-buffered by default.
1322 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
1325 * ports.h (scm_ptobfuns): change fflush return to void.
1326 change flush proc definitions.
1328 * strports.c (scm_call_with_output_string): get size from
1329 buffer instead of port stream.
1330 (st_flush): new proc.
1332 * ports.h (struct scm_port_table): added write_end member,
1333 as an optimisation. set it where write_buf_size is set.
1335 * ports.h (struct scm_port_table): change stream from void *
1336 back to SCM. SCM presumably must be large enough to hold a
1337 pointer (and probably vice versa but who knows.)
1338 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
1340 (scm_puts): rewritten
1341 * fports.c (local_ffwrite, local_fputs): removed.
1342 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)

1347 * ports.c (scm_lfwrite): rewritten using fport.c version.
1349 * fports.c (local_fputc): deleted.
1351 * ports.c (scm_add_to_port_table): initialise write_needs_seek.
1353 * ports.h (scm_ptobfuns): add seek function pointer.
1354 * fports.c: set it to local_seek, new procedure.
1357 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
1358 use ptob for seek. take ptob instead of fport arg.
1360 * ports.h (struct scm_port_table): new member write_needs_seek,
1361 replaces reading member in fport struct.
1363 * vports.c (sfgetc): store the getted char into the buffer.
1364 rename to sf_fill_buffer and install it for fill-buffer in ptob.
1365 the Scheme interface is still a procedure that gets a char.
1366 (scm_make_soft_port): set up the port buffer (shortbuf).
1368 * fports.c (local_fgetc, local_fgets): deleted.
1369 * strports.c (stgetc): likewise.
1370 * ports.c: scm_generic_fgets: likewise.
1372 * ports.h (scm_ptobfuns): add fill_buffer.
1373 * ports.c (scm_newptob): assign it.
1374 * strports.c (scm_mkstrport): set up the buffer.
1375 put just the string into the stream, not cons (pos stream).
1376 (stfill_buffer): new proc.
1378 * ports.h: fport buffer moved into port table: to be
1379 used for all port types.

1388 scm_getpeername, scm_recv, scm_send, scm_recvfrom,
1390 use SCM_FPORT_FDES. use SCM_OPFPORTP not SCM_FPORTP.
1392 * posix.c (scm_getgroups): use SCM_ALLOW/DEFER_INTS.

1457 *fports.c (print_pipe_port, local_pclose, scm_pipob): deleted.

1572 1999-05-09 Jim Blandy <jimb@savonarola.red-bean.com>
1574 * strop.c (scm_string_capitalize_x): Use the SCM object `s' in
1575 error messages, not the uninitialized string `str'. Love that
1578 * strop.c (scm_substring_move_x): New function, which can handle
1579 arbitrary overlapping substrings.
1580 (substring-move-left!, substring-move-right!): These are
1581 now just synonyms for substring-move!.

1594 symbol is returned for any argument where the only difference
1595 between strings is in capitalization.

1609 * strop.h: fixed prototypes.
1611 * strop.c (scm_substring_move_left_x, scm_substring_move_right_x):

1654 1999-03-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1656 * numbers.c (isfinite): Define this macro if not defined: Return a
1657 non-zero value if X is finite. (From ISO C 9x standard.)
1658 (scm_inexact_to_exact): Bugfix: Don't pass NaNs to scm_dbl2big.
1659 (Thanks to Jon Trowbridge and Greg Harvey.)
1661 1999-03-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1686 (scm_system_module_env_p): Assume root environment is no lookup
1689 * debug.c, eval.c, evalext.c, gdbint.c stacks.c:
1690 #include "modules.h".

1699 * error.c (scm_wta): Pass SCM_LIST1 (arg) instead of SCM_EOL to
1700 scm_misc_error when pos is a string. This allows for dispatching
1701 arbitrary error messages with one argument via SCM_ASSERT:

1710 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1712 Most of this batch of changes is about how to deal with extended
1713 types when an object system is loaded into Guile. A nice object
1714 system is capable of representing Guile's types as class objects.
1716 For example, we want a regular expression to be of class <regex>.
1717 But regular expressions are smobs which aren't under direct
1718 control of the object system, so there has to be some mechanism
1719 which informs the object system that a new class should be created
1720 which can represent the smob type. I call this a "wrapper class".
1722 * objects.c: #include "smob.h";
1723 (scm_class_keyword): Removed. (Class is automatically created by
1725 (scm_smob_class): Array of smob classes indexed by smobnum.
1726 (scm_make_extended_class): "Plugin" function pointer for creation
1727 of wrapper classes for smob and struct types.
1728 (scm_class_of): Handle compiled closures. (Currently regarded as
1730 Use scm_smob_class to handle smob types;
1731 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1732 through scm_smob_class;
1735 * smob.c (scm_newsmob): Also create a wrapper class if
1736 scm_smob_class has been initialized.
1738 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1739 type code and smobnum.
1741 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1742 (scm_struct_table): Weak key table with auxilliary information for
1743 struct types. Currently used for names and wrapper classes.
1744 (scm_struct_ihashq): Hash function for structs.
1745 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1746 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1747 for accessing names of vtables. The record implementation in
1748 boot-9.scm currently uses the setter to record the name of record
1749 types. When the object system is initialized, it can use this
1750 information to create wrapper classes with suitable names.
1751 (scm_init_struct): Allocate scm_struct_table.
1752 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1753 (struct tags are a finite resource and we might want to restrict
1754 the use of tags to vtables only. E.g., Goops only uses tags for
1756 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1758 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1761 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1762 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1763 Used for access of struct table entries.
1765 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1766 (scm_hash_fold): New procedure. Used to process all entries in a
1767 hash table (in no particular order).
1769 Argh! For the umpteenth time I got compilation errors because of
1770 the "intuitive" name `kw'. This has to have an end:
1772 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1773 "kw" --> "keywords" everywhere.
1774 (I doubt that this will cause big compatibility problems since the
1775 application interface is unaffected.)
1777 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1779 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1781 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1782 column inums to native form.
1784 Improvement of backtraces: Introduces a new stack narrowing
1785 specifier, #t, for the inner cut. (See further in the comments in
1786 stacks.c:narrow_stack ().)
1788 * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
1789 (Used to flag certain system procedures which shouldn't turn up in
1792 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1793 modules which aren't "user" modules and the code of which
1794 shouldn't turn up in backtraces.)

1797 Extract the lookup closure from an environment.
1798 (scm_system_module_env_p): New function: Return non-#f if MODULE
1801 * stacks.c: #include "eval.h"; #include "procprop.h";

1804 * debug.c (scm_procedure_name): Use name property in the default
1807 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
1809 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1811 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1812 procedure throughout.
1814 * print.c (scm_iprin1): Removed extraneous space when printing
1815 procedure-with-setters.
1817 Entity and operator setter slots were introduced as a complement
1818 to the <procedure-with-setter> type in order to support entities
1819 and operators with setters in a reasonable and efficient way.
1820 * procs.c (scm_procedure, scm_setter): Handle entity and operator
1823 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

1833 1999-03-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1835 * objects.h (SCM_OBJ_CLASS_REDEF): New macro: Find class slots
1836 directly through the instance.
1838 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1840 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1841 scm_struct_i_flags instead of scm_vtable_index_layout!
1843 * list.c (scm_list_star): New procedure.
1845 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1926 SYMB now point to const.
1928 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1930 * print.c (scm_iprin1): Use scm_procedure_name instead of
1931 scm_procedure_property for compiled closures.
1933 * tags.h (scm_tc7_pws): New procedure type. Four representations
1934 for procedure-with-setters were considered before selecting this
1937 1. A closure where the CODE and ENV slots are used to represent
1938 the getter and a new SETTER slot is used for the setter. The
1939 original getter is stored as a `getter' procedure property. For
1940 closure getters, the CODE and ENV slots contains a copy of the
1941 getter's CODE and ENV slots. For subr getters, the CODE contains
1944 2. A compiled closure with a call to the getter in the cclo
1945 procedure. The getter and setter are stored in slots 1 and 2.
1947 3. An entity (i.e. a struct with an associated procedure) with a
1948 call to the getter in the entity procedure and the setter stored
1949 in slot 0. The original getter is stored in slot 1.
1951 4. A new primitive procedure type supported in the evaluator. The
1952 getter and setter are stored in a GETTER and SETTER slot. A call
1953 to this procedure type results in a retrieval of the getter and a
1954 jump back to the correct eval dispatcher.
1956 Representation 4 was selected because of efficiency and
1959 Rep 1 has the advantage that there is zero penalty for closure
1960 getters, but primitive getters will get considerable overhead
1961 because the procedure-with-getter will be a closure which calls
1964 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1965 <procedure-with-setter>, but together with rep 2 it suffers from a
1966 three level dispatch for non-GOOPS getters:
1968 cclo/struct --> dispatch proc --> getter
1970 This is because the dispatch procedure must take an extra initial
1971 argument (cclo for rep 2, struct for rep 3).
1973 Rep 4 has the single disadvantage that it uses up one tc7 type
1974 code, but the plan for uniform vectors will very likely free tc7
1975 codes, so this is probably no big problem. Also note that the
1976 GETTER and SETTER slots can live directly on the heap, using the
1977 new four-word cells.
1979 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,

2064 understand, when I ran automake in the top level directory. This
2065 may be contamination by Cygnus internal releases. If you re-run

2081 Renamed s_bignum --> scm_s_bignum.
2083 * random.c, random.h: New files: Random number support.
2084 Interface same as slib's.
2086 * Makefile.am: Added random.c, random.h, random.x.
2088 * init.c: #include "random.h";
2089 (scm_boot_guile_1): Call scm_init_random ().
2091 1998-12-23 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2093 * Makefile.am: New files: guardians.c, guardians.x, guardians.h
2095 * guardians.c, guardians.h (scm_make_guardian,
2096 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
2097 scm_get_one_zombie, scm_init_guardian): This is an implementation
2098 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
2099 David Eby (1993) "Guardians in a Generation-Based Garbage
2100 Collector" ACM SIGPLAN Conference on Programming Language Design
2101 and Implementation, June 1993 ftp://ftp.cs.indiana.edu
2102 /pub/scheme-repository/doc/pubs/guardians.ps.gz
2103 Author: Michael N. Livshin.
2105 * gc.h (SCM_MARKEDP, SCM_NMARKEDP): New macros.
2107 * gc.c (scm_igc): Call scm_guardian_gc_init and
2108 scm_guardian_zombify.
2110 * init.c (scm_boot_guile_1): Call scm_init_guardian.
2112 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2114 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
2117 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2119 Move the procedure slots of entities to invisible slots (so that
2120 we can have operator class objects which themselves are entities).
2121 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
2122 SCM_STRUCTF_ENTITY): New constants.
2124 * struct.c (scm_make_struct): Allocate "invisible" room for
2125 procedures if SCM_STRUCTF_ENTITY is set in vtable.
2127 * gc.c (scm_gc_mark): Mark entity procedures.
2129 * struct.c, struct.h (scm_alloc_struct): Renamed from alloc_struct
2131 (scm_struct_init): Renamed from init_struct and made global.

2134 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
2135 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
2137 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
2139 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
2140 of syntactic forms, similar to SCM_PROC.
2141 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
2142 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
2143 for the name symbols when needed.
2145 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
2147 * Makefile.in: Regenerated.
2149 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
2151 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
2152 take the address of _into; it might be a register. Just have
2153 scm_debug_newcell return the new cell.
2154 * gc.c (scm_debug_newcell): Just return the new cell, instead of
2155 taking the address of a place to store it as an argument.
2156 * gc.h (scm_debug_newcell): Change declaration.
2157 (Thanks to Greg Harvey.)
2159 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2161 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
2162 Replaces old names serial-array-copy! and serial-array-map!.
2164 * evalext.c (map-in-order): New name. Replaces serial-map.
2166 1998-12-05 Jim Blandy <jimb@totoro.red-bean.com>
2168 * smob.c (freeprint): New function.
2169 (freecell): Use it to print freed objects, for slightly easier
2172 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2174 * backtrace.c (display_frame): Made more robust. Doesn't throw an
2175 error if no source properties can be found for a frame. (Thanks
2176 to Christian Lynbech.)
2178 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2180 * objects.h: Removed slots direct_supers and direct_slots from the
2181 definitions of the rudimentary classes described by objects.h.
2183 * objects.c, objects.h (scm_entity_p): New procedure. Together
2184 with the predicates scm_procedure_p and scm_struct_p, this
2185 predicate makes it possible to differ between structs, entities
2188 * modules.c, modules.h (scm_resolve_module): New function.
2190 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2192 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
2193 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
2196 * objects.c (scm_entity_p): New procedure.
2198 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
2199 for asubrs, rpsubrs, lsubrs and lsubr_2s.
2201 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2203 * procprop.h (scm_i_procedure_arity): Added declaration.
2205 * procprop.c (scm_i_procedure_arity): Made global; New code to
2206 handle operators and entities.
2207 (scm_procedure_property): No need to call scm_procedure_p since
2208 scm_i_procedure_arity now does all necessary type checking.
2209 Added #include "objects.h".
2211 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2212 s_add_hook_x --> s_remove_hook_x.
2213 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
2214 Added #include "procprop.h"
2216 * feature.c, feature.h (scm_reset_hook_x): New procedure.
2217 (scm_make_hook): Optional argument defines number of arguments to
2219 (scm_make_named_hook): Take number of args as second arg.
2220 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2221 boot-9.scm for a while); First arg is the hook. The rest are
2222 arguments passed on to the hook procedures.
2224 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
2226 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2227 scm_logbit_p): Do the computation in ulongs. This is not as nice
2228 as doing it in bignums, but at least it's good enough for
2229 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2231 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2232 subexpressions. (Thanks to Charbel Jacquin.)
2234 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
2236 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
2237 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2238 (scm_make_named_hook): New function.
2240 * feature.c: Added #include "eval.h".
2242 * modules.c (scm_make_module): Beautify the module.
2244 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2246 * modules.c, modules.h: New files: C interface to modules. (This
2247 is necessary in order to interface the object system to Guile
2248 properly. The guts of these modules will be replaced by the new
2249 module system in the future.)
2251 * init.c: Added #include "modules.h"
2252 (scm_boot_guile_1): Call scm_init_modules.
2253 (invoke_main_func): Call scm_post_boot_init_modules.
2255 * Makefile.am: Added modules.c, modules.x, modules.h.
2257 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
2259 * procs.c: #include "objects.h"
2260 (scm_procedure_p): Return #t also on structs which are operators.
2262 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
2263 <operator-metaclass> and <entity-class> to <standard-class>,
2264 <operator-class> and <entity> in order to conform with STKlos
2267 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
2268 which isn't an operator.
2269 (SCM_APPLY): Ditto, but jump to badproc.
2271 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
2273 * eval.c (SCM_CEVAL): Allow structs implanted in code.
2274 Previously, structs implanted in code were interpreted as forms
2275 the operator of which was a gloc. We solve this by checking for
2276 the zero in the emulated vcell in the struct vtable. Since
2277 implanted structs always will look like forms with a gloc
2278 operator, execution will only be slowed down by maximally one
2279 extra test-and-branch per application.
2281 * evalext.c (scm_definedp): Removed check for isyms; Added a
2282 second optional argument: It is now possible to supply an
2283 evaluation environment in which to look for the symbol.
2285 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2287 * readline.c (scm_init_readline): Set
2288 rl_basic_word_break_characters. (Thanks to Ian Grant.)
2290 * coop.c (coop_condition_variable_wait): Removed
2291 (coop_condition_variable_wait_mutex): Folded logic of
2292 coop_mutex_unlock into coop_condition_variable_wait_mutex to
2293 prevent condvar signal lossage. Previously, another thread could
2294 start to run after unlocking the mutex but before putting the
2295 current thread on the wait queue. If that thread then would
2296 signal the first, the signal would be lost. (Thanks to Christian
2299 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2301 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
2304 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2306 * objects.c (scm_i_make_class_object): Renamed from
2307 make_class_object; exported; error checking moved to
2308 scm_make_class_object and scm_make_subclass_object.
2309 (scm_make_class_object, scm_make_subclass_object): Use
2310 scm_i_make_class_object.
2311 (scm_make_subclass_object): Let the subclass have same metaclass
2314 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2316 * debug.c (scm_debug_options): Bugfix: Set the value of
2317 scm_stack_checking_enabled_p after setting debug options;
2318 #include "stackchk.h". (Thanks to Richard Polton.)
2320 1998-11-13 Radey Shouman <rshouman@metro2000.com>
2322 * unif.c (scm_array_contents): removed unnecessary test for 0
2325 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2327 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
2328 Replaced by macro `collect' in boot-9.scm.
2330 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2332 * eval.c (scm_copy_tree): Copy source properties if existent.
2334 * debug.c (scm_start_stack): Copy source when evaluating. (If we
2335 don't, we may end up passing memoized source to a transformer.)
2337 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2339 * stack.c (get_applybody): Help function which lookups the first
2340 body form of the apply closure.
2341 (read_frames): Prevent the source of the first form of the apply
2342 closure from being recorded. This would only be confusing.
2344 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
2345 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
2347 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
2349 * stacks.c (read_frame): Bugfix: Removed lingering `else'
2351 (read_frames): Use SCM_MACROEXPP.
2353 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2355 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
2356 don't contain interesting information since all arguments are
2357 present in the frame which applies the compiled closure anyway.);
2358 Skip the transformer application frames.
2360 * print.c (scm_iprin1): Print gsubrs as primitives.
2362 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2364 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
2366 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
2367 that we can identify these in a backtrace. (This change doesn't
2368 introduce any significant speed penalty.)
2370 * eval.c: Added note about `serial-map' using scm_map.
2372 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2373 readline options. They should reside in their own options array.
2375 * readline.c, readline.h (scm_readline_options,
2376 scm_readline_opts): Moved readline options here.
2378 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2380 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2381 SCM_ROCHARS instead of SCM_CHARS.
2383 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2384 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2386 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2388 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2389 This is quite important since the latter clears the
2390 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2391 every single character read...
2393 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2395 * print.c (scm_iprin1): Removed suspect looking (and indeed
2396 malevolent) semicolon after test for user supplied closure print
2397 procedure. (Thanks to Telford Tendys.)
2399 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2400 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2401 starting to search the list. Removed call to sloppy_mem_check.
2403 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2404 procedures: Same as scm_delq_x et al, but delete maximally one
2407 * options.c (scm_options, scm_init_options): GC-protect option
2408 values of type SCM. (Thanks to Telford Tendys.)
2410 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2412 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2413 make sure that there always is a "real" scm_lookupcar.
2415 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2417 * read.c, read.h (scm_read_opts): New read options
2418 "history-length" and "history-file".
2419 (scm_read_options): Stifle history to history length.
2421 * readline.c (scm_read_history, scm_write_history): New procedures.
2423 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2425 * eval.h (scm_macro_eval_x): Removed declaration.
2427 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2428 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2429 Renamed and made global.
2431 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2432 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2434 * evalext.c, evalext.h: New files. Contain non-R5RS things
2435 having to do with evaluation.
2437 * evalext.c (scm_serial_map): New procedure: Version of `map'
2438 which guarantees that the procedure is applied to the lists in
2440 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2441 returns a list of the results of the body forms instead of the
2442 result of the last body form.
2443 (scm_definedp, scm_m_undefine): Moved from eval.c
2445 * evalext.h (scm_m_sequence_to_list): Added declaration.
2447 * macros.c, macros.h: New files.
2448 (scm_procedure_to_syntax, scm_procedure_to_macro,
2449 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2450 scm_macro_name, scm_macro_transformer): Moved from eval.c
2451 (scm_make_synt): Moved from eval.c
2453 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2455 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2458 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2460 * debug.c, print.c: Added #include "macros.h".
2462 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2464 This change adds the ability to use `unread-char' multiple times
2465 without interspersed reads and adds the new procedure
2466 `unread-string'. The change is optimized for the common case of
2467 unreading a single character. This is also the reason behind the
2468 choice to store characters in the port itself: in most cases no
2469 extra malloc is required.
2471 The amount of code in some macros in ports.h has been increased to
2472 the extent that they would fit better as C functions, but, since
2473 this code belongs to the port representation, such functions
2474 should be placed in ports.c which would cause calls back and forth
2475 between ports.c and genio.c. That is not good for performance.
2476 Also, keeping them as macros allows the compiler to do some
2477 optimizations which are needed to make the current interface
2478 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2480 One benchmark (Guile startup time) indicates an increase of
2481 loading speed of 1%. Another (reading (using `read') boot-9.scm
2482 10 times) shows no change in performance.
2484 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2485 made to find a beautiful solution.)
2487 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2488 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2489 character. (SCM_CLRDY clears all.)
2490 (SCM_N_READY_CHARS): New macro: Returns number of unread
2491 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2492 (struct scm_port_table): New fields: `entry' contains port table
2493 index, `cp' points to last unread char, `cbuf' is the buffer for
2494 unread chars, `cbufend' points after end of the character buffer.
2496 * ports.h, ports.c (scm_unread_string): New procedure.
2497 (scm_grow_port_cbuf): New function.
2499 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2501 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2502 to read unread characters. Use SCM_TRY_CLRDY instead of
2505 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2507 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2509 * genio.c, genio.h (scm_ungets): New function.
2511 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2514 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2516 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2517 declarations. (Thanks to Russ McManus.)
2519 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2521 * numbers.c (num2long): As a software archeologist, I'm proud of
2522 this finding! :) Preliminary dating suggests an almost 4 year old
2523 remnant from the SCM ancestor. The sample has been removed from
2524 the finding site and is now safely stored in the repository.
2526 * numbers.h: Removed prototype for num2long.
2528 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2530 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2531 array as second arg.
2532 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2533 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2534 * gh.h: Updated and added prototypes.
2536 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2538 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2540 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2542 * guile-snarf.in: Never generate an empty file. (Thanks to
2545 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2546 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2547 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2548 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2549 gh_new_procedure5_0): Specify argument types, to appease C++
2550 compilers. (Thanks to Brad Bowman.)
2552 Bug reports from Russ McManus:
2553 * guile-snarf.in: If the CPP environment variable is set, use that
2554 as the C preprocessor, instead of the preprocessor autoconf
2556 * snarf.h (SCM_PROC): Cast the function pointer passed to
2557 scm_make_gsubr, to satisfy C++.
2559 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2560 Use the handler passed, instead of ignoring it and using
2561 gh_standard_handler. (Thanks to Etienne Bernard.)
2563 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2565 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2568 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>
2570 * __scm.h, alist.c, async.c, async.h, backtrace.h, chars.c,

2588 * script.c (scm_compile_shell_switches): Define
2589 use-emacs-interface in the root module, so the repl code can see
2590 it. See today's change to top-repl in ice-9/boot-9.scm.
2592 * filesys.c (set_element, get_element): Make sure that `element'
2593 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2594 Boekemeier and Jorgen "forcer" Schaefer.)
2596 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2598 * chars.c (scm_charnames): In ASCII character name table, make
2599 newlines print as #\newline by default, not #\nl.
2601 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2602 alphabetical order. Oh thrills. But it helps me know how far
2603 along in the compilation I am.
2604 * Makefile.in: Regenerated.
2606 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2608 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2609 #bytes(...) to #y(...), and syntax for short vectors from
2610 #short(...) to #h(...). This may seem nutty, but, like the other
2611 uniform vectors, byte vectors and short vectors want to have the
2612 same print and read syntax (and, more basic, want to have read
2613 syntax!). Changing the read syntax to use multiple characters
2614 after the hash sign breaks with the conventions used in R5RS and
2615 the conventions used for the other uniform vectors. It also
2616 introduces complexity in the current reader, both on the C and
2617 Scheme levels. (The Right solution is probably to change the
2618 syntax and prototypes for uniform vectors entirely.)
2620 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2622 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2623 (Thanks to Jorgen "forcer" Schaefer.)
2624 * ports.h (SCM_NOFTELL): New flag.
2625 * fports.c (local_fgets): If it's set, use the generic fgets.
2626 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2628 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2630 * script.c (scm_compile_shell_switches): Add handling of -q switch
2631 (inhibit loading of user init file).
2632 (scm_shell_usage): Add usage text for -q switch.
2633 (scm_compile_shell_switches): Always load user init file first if
2634 it is loaded at all.
2636 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2638 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2639 and is now broken under NetBSD. I can't fathom what it's trying
2640 to do, so I've replaced it with something that I do understand,
2641 which seems to work, and which isn't broken on NetBSD. "Progress?
2642 You Decide." (Thanks to Perry Metzger.)
2644 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2645 signed/unsigned comparison.
2647 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2649 Warning fixes from Greg Harvey:
2650 * unif.c (scm_array_set_x): initializer for pos
2651 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2652 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2653 initializers for field_type, since EGCS so desparately wants to
2655 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2656 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2657 when GUILE_DEBUG is defined.
2658 * dynwind.h (scm_wind_chain): Same.
2659 * ports.h (scm_pt_size, scm_pt_member): Same.
2660 * print.h (scm_current_pstate): Same.
2661 * procs.h (scm_make_cclo): Same.
2663 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2665 Handle short and long long uniform arrays properly. (Thanks to
2667 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2668 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2669 scm_tc7_llvect (long long vectors).
2671 Change the way libguile and boot-9.scm are timestamped, to try to
2672 get rid of these spurious mismatch warnings. Now both
2673 libguile/versiondat.h and ice-9/version.scm are generated directly
2674 by the configuration process, rather than having version.scm
2675 generated directly, and libguile/versiondat.h generated by the
2676 Makefile, which is generated by configure. It seems that
2677 sometimes the Makefile would change, but versiondat.h depends on
2678 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2679 * Makefile.am (versiondat.h): Target removed; this is generated
2680 directly by the configure script now.
2681 (BUILT_SOURCES): Remove versiondat.h.
2682 * versiondat.h.in: New file, transformed by the configure script
2684 * Makefile.in: Regenerated.
2686 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2687 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2688 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2689 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2690 if we want to use them in a header file some day, we can. (Thanks
2691 to Michael Livshin.)
2693 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2694 SCM numbers, so we won't have rollover problems; the range of a
2695 signed long in milliseconds is about 25 days. (Thanks to Karl
2698 Don't redefine sleep and usleep; fix this problem now.
2699 * coop.c (sleep, usleep): Remove declarations; we don't use or
2700 redefine these any more.
2701 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2702 job of usleep and sleep in a thread-friendly way. We can use
2703 these in the rest of Guile. Define versions for systems both with
2704 and without iselect.
2705 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2706 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2707 we're just using it, not redefining it, we can use a K&R style
2709 (sleep): Declare this, too, if the system hasn't.
2710 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2711 scm_uthread_sleep if they're available; otherwise, just call the
2713 * scmconfig.h.in: Regenerated.
2715 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2717 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2719 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2721 * threads.c: Doc fix.
2723 The argument type of usleep varies from system to system,
2724 as does the return type. We really shouldn't be redefining usleep
2725 at all, but I don't have time to clean that up before the 1.3.
2726 release. It's on the schedule for afterwards. (Thanks to Julian
2728 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2730 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2731 * scmconfig.h: Regenerated.
2733 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2734 right way to handle system variation. Autoconf's approach is the
2736 * simpos.h (scm_software_type): Declaration deleted.
2738 * script.c (scm_find_executable): Don't test if unix is #defined
2739 here; first, NetBSD doesn't #define it, and second, it's the wrong
2740 way to go about these things. (Thanks to Perry Metzger.)
2741 (dld_find_executable): Delete this MSDOS support code. This isn't
2742 the way we want to support this; it needs to be rethunk at a
2745 * genio.c (scm_do_read_line): Don't just politely check that the
2746 line was either non-empty or EOF. Abort if it's empty and not
2749 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2751 * scmconfig.h.in: Regenerated.
2753 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2756 * genio.c (scm_do_read_line): Count lines correctly when the file
2757 doesn't end in a newline.
2759 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2761 * genio.c (scm_do_read_line): Maintain the line count correctly.
2762 (Thanks to Harvey J. Stein and Greg Harvey.)
2764 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2767 * numbers.c (big2str): Protect t from garbage collection until
2768 we're done. (Thanks to Gary Houston.)
2770 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2772 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2774 * Makefile.in: Regenerated.
2776 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2777 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2780 Do magic to mix reads and writes on stdio FILE-based ports.
2781 (Thanks to Christian Lynbech.)
2782 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2784 (pre_read, pre_write): New functions.
2785 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2786 local_fputs): Call them.
2787 (local_fflush): Mark the port as ready for reading and writing.
2788 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2789 flags on new port objects. This might not be accurate --- who
2790 knows what state the FILE * is in when we get it --- but it won't
2791 do extraneous calls to fflush or fseek, so it's no worse than the
2792 behavior before this change.
2793 * ports.h: Add comment.
2795 Centralize the creation of port objects based on stdio FILE * in
2796 fports.c; don't just throw them together anywhere.
2797 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2798 what the rest of Guile wants. Don't set the revealed count;
2799 that's only appropriate for stdin, stdout, stderr.
2800 (scm_standard_stream_to_port): This function does set the revealed
2802 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2803 not scm_stdio_to_port.
2804 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2805 * fports.c (scm_open_file): Same.
2806 * posix.c (scm_pipe): Same.
2807 * socket.c (scm_sock_fd_to_port): Same.
2808 * ioext.c (scm_fdopen): Same.
2809 (scm_freopen): Moved from here to...
2810 * fports.c (scm_freopen): ... here. This is really something that
2811 munges the internals of an fport, so it should go here.
2812 * fports.h (scm_stdio_to_port): Adjust prototype.
2813 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2814 * ioext.h (scm_freopen): Prototype removed.
2816 * filesys.c (set_element, get_element): This can work on both pipe
2817 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2820 * scmconfig.h.in: Regenerated.
2822 Change the definition of the functions in scm_ptobfuns so that
2823 they get passed the port object, not the port's stream.
2824 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2825 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2826 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2827 Pass the port itself to the scm_ptobs function.
2828 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2829 scm_generic_fgets): Same.
2830 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2831 getc_void_port, fgets_void_port, close_void_port): Just change the
2832 argument names; these functions don't really do anything.
2833 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2834 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2835 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2836 Also, use prototyped definitions, and get rid of the extra
2838 (scm_fptob, scm_pipob): We don't need casts here any more.
2839 * strports.c (prinstpt): Use prototype declarations.
2840 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2841 and use SCM_STREAM to get the string info. Also, use prototyped
2842 definitions, and get rid of the extra declarations.
2843 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2846 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2847 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2849 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2850 scm_fgets, for consistency.
2851 (scm_fptop, scm_pipob): References updated.
2853 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2855 Include the source location in error messages for scripts.
2856 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2857 stack is still there when we catch the error.
2858 * throw.c (handler_message): If we are handling an error with a
2859 message, then put together the proper arguments and call
2860 scm_display_error, instead of scm_display_error_message. That
2861 displays source location, if it can find it.
2863 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2865 * gc.c (scm_unprotect_object): Change this so that calls to
2866 scm_protect_object and scm_unprotect_object nest properly.
2867 (scm_protect_object): Doc fixes.
2869 * strings.c (scm_string_set_x): Require the argument to be a
2870 writable string, not a substring or a symbol.
2871 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2872 (Thanks to John Redford and Charbel Jacquin.)
2874 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2876 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2878 * eval.c (safe_setjmp): Remove this misunderstanding.
2879 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2882 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2884 * libguile.h: Mark these as C declarations, for compilation by C++
2887 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2888 __cplusplus clause. I seriously doubt this ever worked the way
2889 the author seems to have intended.
2891 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2893 Utterly needless cleanups to hopelessly messy code.
2894 * ports.c: Doc fixes.
2895 (scm_fflush): Moved to ...
2896 * genio.c (scm_fflush): ... here, amongst all the other port
2897 method invocation functions.
2898 * genio.h, ports.h: The prototype moves too.
2900 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2902 * backtrace.c (display_error_body): The current frame does not
2903 always have a parent frame; consider a function called directly
2904 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2907 * alloca.c (alloca): Undo yesterday's changes, and simply call
2908 malloc directly for storage, and abort if we don't get what we
2909 want. The situation is much simpler --- just call malloc. Emacs
2910 has bizarre/evil requirements (signal handlers might malloc unless
2911 you set this global flag, so you have to set the flag around all
2912 calls to malloc) which we are certainly not going to conform to,
2913 so we can do the simple and obvious thing.
2915 * coop.c (coop_condition_variable_wait): Make this function
2916 static. It's only useful internally --- you should never just
2917 wait on a condition variable.
2918 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2920 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2922 * unif.c (scm_array_set_x): Accept any kind of number as an
2923 element for a uniform vector of doubles. This is more consistent
2924 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2926 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2927 works; I can't conveniently test it myself. (Thanks to Dvid
2928 Tillman for the bug report.)
2930 * init.c: Doc fixes.
2932 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2933 from here, not from scm_compile_shell_switches (which is a pretty
2934 dumb place to do it).
2935 (scm_load_startup_files): New function.
2936 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2937 * script.c (scm_compile_shell_switches): Don't load the startup
2939 (scm_ice_9_already_loaded): Variable moved.
2940 * init.c (scm_load_startup_files): Prototype for new function.
2941 * gh_init.c (gh_enter): Doc fix.
2943 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2945 Some anti-warning changes from Greg Harvey.
2946 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2947 warnings when it doesn't understand our NORETURN declarations in
2949 * posix.c (scm_mknod): Similar.
2951 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2953 * posix.c (scm_getpwuid): If we can't find an entry, return our
2954 own message, instead of using scm_syserror --- the getpwMUMBLE
2955 functions don't set `errno' to anything interesting.
2957 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2959 Get rid of warnings from the cooperative threading system.
2960 * threads.h (scm_single_thread_p, scm_yield,
2961 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2962 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2963 scm_wait_condition_variable, scm_signal_condition_variable): Add
2964 prototypes for these Scheme-visible functions.
2965 * coop-defs.h (coop_next_runnable_thread,
2966 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2967 Prototypes for these here, even though they're from iselect.c.
2968 (coop_condition_variable_wait, coop_join): Add prototypes.
2969 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2970 scm_threads_free_condvar): Make these smob functions static.
2971 * coop-threads.h (coop_init): Give this a real prototype.
2972 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2973 (coop_next_runnable_thread): No need to provide prototype; it's in
2976 * scmconfig.h.in: .detarenegeR
2978 * iselect.c, threads.c: Doc fixes.
2980 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2982 * Makefile.in: Regenerated with a patched automake, to get
2983 dependency generation right when using EGCS.
2985 * inet_aton.c (inet_aton): Add prototype, to remove compiler
2986 warning. (Thanks to Robert Pluim.)
2988 * inet_aton.c (inet_aton): Reassure the compiler that the
2989 arguments to the <ctype.h> macros are all unsigned characters, not
2992 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2994 Getting rid of more warnings...
2995 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
2996 today's change to ../configure.in.
2997 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
2998 * scmconfig.h.in: Regenertaded.de.,.__
2999 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
3000 (scm_localtime, scm_mktime): Use a const char * to manipulate the
3003 * readline.c: Doc fix.
3004 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
3005 * readline.h (scm_filename_completion_function): Add prototype.
3006 (scm_init_readline): Make this into a prototype.
3008 * readline.c (scm_filename_completion_function): Use SCM_PROC to
3009 declare this, instead of calling scm_make_subr manually.
3011 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
3013 * readline.h (scm_init_readline): Add prototype for this.
3014 (scm_init_readline): Make this a real prototype.
3016 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
3018 Warning fixes from Maciej Stachowiak:
3019 * backtrace.h (scm_display_application, scm_backtrace): Add
3021 * debug.c (scm_m_start_stack): Make this function static.
3022 * fluids.h (scm_fluid_p): Add prototype.
3023 * procprop.c (scm_i_procedure_arity): Make this function static.
3024 * regex-posix.c (scm_regexp_error_msg): Make this function static.
3025 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
3026 * root.h (scm_dynamic_root): Add external prototype.
3027 * scmsigs.h (scm_usleep): Add external prototype.
3028 * script.h (scm_init_script): Use prototype, not K&R decl.
3029 * stacks.h (scm_stack_id): Add external prototype.
3030 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
3032 1998-09-30 Mark Galassi <rosalia@cygnus.com>
3034 * gh.h: took out the definitions of vset and vref, since they are
3035 replaced by the proper vector routines that correspond to the R4RS
3038 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
3040 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
3041 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
3042 third argument, a C expression that should result in a SCM value,
3043 which is used to initialize the variable. Reimplemented
3044 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
3047 * version.h (scm_libguile_config_stamp): Add prototype.
3048 (From Maciej Stachowiak.)
3050 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
3052 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
3053 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
3055 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
3057 * print.c (scm_iprin1): Rather than having one i, and using it in
3058 several places, declare a fresh i local to each block where it is
3059 used, and give it a signedness appropriate to its use in each case.
3060 (scm_iprlist): Same.
3062 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
3063 comparison warnings.
3065 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
3066 signed/unsigned clashes.
3068 * posix.h (scm_tmpnam): Added prototype.
3070 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
3071 scm_make_subclass_object): Add external prototypes.
3073 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
3074 comparison is okay here.
3076 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3078 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3079 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3081 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3084 * load.c (swap_port): Make this function static.
3086 * load.c (scm_search_path): Make max_path_len and max_ext_len
3087 unsigned, since they're compared against string sizes.
3089 * load.c (init_build_info): Make i unsigned.
3091 * ioext.h (scm_read_line): Add prototype.
3093 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3094 scm_hash_fn_remove_x): Make hash bucket index local variable k
3095 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3096 accurately as possible.
3098 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3099 comparisons, and range checking to make sure those casts are
3102 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3103 signed/unsigned comparisons.
3105 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3106 avoid signed/unsigned comparisons.
3107 * smob.h (scm_numsmob): Change extern declaration to match.
3109 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3110 avoid signed/unsigned comparisons.
3111 * ports.h (scm_numptob): Change extern declaration to match.
3112 (scm_current_load_port, scm_set_port_line_x,
3113 scm_set_port_column_x): New prototypes.
3115 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3116 test code, and it causes warnings.
3118 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3119 gh_uniform_vector_ref): Added prototypes.
3121 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3122 debugging support unconditionally. That's backtrace.c, stack.c,
3123 debug.c, and srcprop.c.
3124 (EXTRA_libguile_la_SOURCES): Omit those from here.
3125 * Makefile.in: Regenerated.
3127 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3129 * options.c (scm_options): Bugfix: Allow empty list of options!
3131 * debug.c, debug.h (scm_single_step): Removed.
3132 (scm_with_traps): New procedure. This procedure could easily be
3133 written in Scheme but needs to be highly optimized.
3135 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3137 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3138 Check SCM_TRAPS_P before trapping.
3140 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3142 Changes to avoid signed/unsigned comparison warnings.
3143 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3144 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3145 so they can have appropriate types for each application. Make i
3146 signed. Use initializers in some spots. I'll probably pay for
3148 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3149 (scm_must_realloc): Make nm unsigned.
3150 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3151 (scm_init_storage): Use prototype-style definition, and make the
3153 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3154 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3156 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3157 avoid signed/unsigned comparison warnings, and because the return
3158 value of readlink may be -1. Don't bother casting the third
3159 argument to readlink.
3161 * filesys.c (scm_dirname, scm_basename): Move these to their own
3162 page, at the end of the file.
3163 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3165 * eval.h (scm_eval_options_interface): Add external prototype for this.
3166 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3168 * eval.c (scm_lookupcar1): Make this static.
3170 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3171 Make these prototype declarations, not K&R-style.
3173 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3174 unsigned comparison warning.
3176 * appinit.c: File removed. It had a single function in it, empty,
3177 whose reason for existence is explained in no documentation or
3178 comment. I think it's there as a default for some Tcl-style
3179 initialization, but Tcl abandoned that approach a while ago.
3180 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3181 (BUILT_SOURCES): Remove appinit.x.
3182 * Makefile.in: Regenerated.
3184 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3186 * Makefile.in: Regenerated using the last public version of
3187 automake, not the hacked Cygnus version.
3189 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3191 Remove Totoro kludge.
3192 * Makefile.in, scmconfig.h.in: Regenerated.
3193 * init.c, readline.c: Don't check if TOTORO is #defined.
3195 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3197 * Makefile.am: Adjust for new thread configuration system.
3198 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3199 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3201 (THREAD_LIBS): Definition deleted; automake will generate such
3202 things automatically.
3203 * Makefile.in: Regenerated.
3205 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3207 Simplify smob and port marking; set the mark bit in the generic
3208 marking code, and make marker routines only responsible for
3209 turning up outgoing pointers.
3210 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3211 before calling the marking function. Don't call the marking
3212 function if it's zero.
3213 * markers.c (scm_mark0): Just return #f. This function isn't
3214 necessary at all now, but it's harmless to call it. We'll leave
3215 it in so other folks' code doesn't croak at link time.
3216 (scm_markcdr): Don't call SCM_SETGC8MARK.
3217 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3218 * dynl.c (mark_dynl_obj): Same.
3219 * root.c (mark_root): Same.
3220 * srcprop.c (marksrcprops): Same.
3221 * unif.c (markra): Same.
3222 * variable.c (scm_markvar): Same.
3223 * ports.c (scm_markstream): Same.
3224 (void_port_ptob): Specify zero for our marking function.
3225 * debug.c (debugobjsmob): Same.
3226 * dynwind.c (guardsmob): Same.
3227 * filesys.c (dir_smob): Same.
3228 * fluids.c (fluid_smob): Same.
3229 * fports.c (scm_fptob, scm_pipob): Same.
3230 * mallocs.c (mallocsmob): Same.
3231 * regex-posix.c (regex_t_smob): Same.
3232 * smob.c (freecell, flob, bigob): Same.
3233 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3234 * throw.c (jbsmob, lazy_catch_funs): Same.
3236 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3238 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3239 scm_copy_tree on code in order not to let memoized code to leak
3240 out. Thus, scm_copy_tree needs to copy vectors as well since
3241 quasiquote can introduce evaluated code also inside vector
3244 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3246 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3248 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3249 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3252 * unif.c: Say that ivect and uvect are of type signed and unsigned
3253 long instead of int in commentary so that it correctly describes
3256 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3258 * stime.c: Removed declaration of strptime. (It should be
3259 declared by the system headers. If it turns out that some systems
3260 don't, we'll handle that then.) (Thanks to Greg Troxel.)
3262 * stime.h: Renamed TIMEH --> STIMEH
3264 * backtrace.c (scm_display_error, scm_display_backtrace): In order
3265 to increase portability, don't use structure assignment.
3266 (Thanks to Nicolas Neuss.)
3268 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
3270 (finalize_fd_sets): Added empty statement after last case label.
3271 (Thanks to Nicolas Neuss.)
3273 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
3276 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
3278 * init.c, readline.c: OK, I won't have these readline.x bug
3279 reports anymore. We've had them since April. The current reason
3280 is a completely unintelligible failure of totoro.red-bean.com to
3281 do the test for rl_getc_function in libreadline correctly. This
3282 kludge overrides the test if we're on totoro so that the snapshot
3283 generation process can work.
3285 * readline.c: Define a strdup replacement if not existent on system.
3287 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3289 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
3290 This change makes scm_make_vector R5RS compatible. We cannot keep
3291 the third argument since people want to be able to deduce the form
3292 of the C function call only by looking at R5RS. (At the same time
3293 we have removed some unnecessary complexity!)
3295 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
3296 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
3297 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
3298 argument in call to scm_make_vector.
3300 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3302 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
3303 This macro is useful in applications.
3305 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3307 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
3308 (scm_parse_path, scm_search_path): New Scheme level procedures.
3310 * load.h (scm_internal_parse_path, scm_parse_path,
3311 scm_search_path): Declared.
3313 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3315 * filesys.c (dirname, basename): New procedures.
3317 * init.c (scm_boot_guile_1): Removed condition around
3320 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
3321 new data type (guards) for representation of C level guards and
3322 data on the wind chain.
3323 (scm_internal_dynamic_wind): New function.
3325 * dynwind.h: Declare scm_internal_dynamic_wind.
3327 * root.h (scm_root_state): Added scm_cur_loadp.
3329 * root.c (mark_root): Added comment about cur_loadp.
3331 * load.c: #include "dynwind.h";
3332 (scm_primitive_load): Use scm_inner_dynamic_wind to update
3335 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
3337 * ports.c (current-load-port): New procedure.
3339 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3341 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
3342 not a tty, return #f.
3344 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
3345 to Julian Satchell and Roland Kaufmann.)
3347 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
3348 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
3350 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3352 * debug.h, debug.c (scm_start_stack): New function. Implements
3353 the guts of old scm_m_start_stack.
3355 * debug.c (scm_m_start_stack): Use scm_start_stack.
3357 * init.c (scm_start_stack, scm_restart_stack): Renamed to
3358 start_stack and restart_stack. (These have static scope.)
3360 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3362 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
3363 readline functions to come in release 2.3. (Thanks to Chet
3365 (handle_errors): Use the above functions.
3367 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3369 * readline.c: Improvements for readline support: Handle errors
3370 better; Implement before-read-hook.
3372 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3374 * init.c (scm_boot_guile_1), readline.c: Test for
3375 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3376 assure that we have version >= 2.1.)
3378 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3380 * readline.c (scm_readline): Defer interrupts while we're calling
3383 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3384 away the string to add_history.
3385 (completion_function): Do completion for readline. (Thanks to
3387 (scm_filename_completion_function): New procedure: Filename
3389 (current_input_getc): New function. Use this one instead of
3390 standard getc from readline.
3392 * throw.c, throw.h (scm_handle_by_throw): New function: This
3393 handler throws errors to next handler on the dynwind chain.
3395 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3397 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3400 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3402 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3404 (scm_procedure_properties): Modified to return arity together with
3406 (scm_procedure_property): Added the read-only property `arity'.
3407 (scm_set_procedure_property_x): It is an error to set the `arity'
3410 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3411 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3413 * procprop.h (scm_sym_arity): New symbol.
3415 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3416 to set the dispatch procedure of an operator or entity object.
3418 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3419 Made procedure slots read-only.
3421 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3422 scm_tcs_cons_gloc case in zero args switch; Fixed args
3423 construction for operators in scm_tcs_cons_gloc case in two args
3426 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3428 * fluids.c: Removed use of assert.h (in order to avoid
3431 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3433 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3435 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3436 change makes the evaluator safer at the cost of evaluation speed.
3437 It handles the case when the user has added a non-immediate
3438 improper end of the application form, e.g., `(+ 0 . x)'.
3439 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3440 minimize the extra cost as much as possible. The new code is
3441 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3442 problem with structs planted directly in the code (e.g. by a
3443 macro). This no longer causes segmentation fault. (Thanks to
3446 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3447 arg `proc' in order to be able to throw errors; New argument
3450 * Removed extra #include "debug.h"
3452 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3454 * scmsigs.c: Declare usleep as returning void on some systems.
3455 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3458 * coop.c (usleep): Return void on some systems.
3460 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3462 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3464 * coop.c: Changed return type of usleep to int.
3466 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3467 isn't found in the OS.
3469 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3470 isn't enabled. (Thought that I had made this change ages ago...)
3472 * iselect.c: Declare bzero if not defined by OS.
3474 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3476 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3477 condition. (Thanks to John Tobey.)
3479 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3480 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3483 * __scm.h: Start the long-term project of moving to POSIX threads.
3484 Phase 1: Classification of all critical sections.
3485 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3486 for A sections. (See comments in __scm.h for details.)
3488 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3489 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3491 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3493 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3494 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3495 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3496 dependencies on $(srcdir)/Makefile.in
3497 $(top_builddir)/config.status in order to avoid circularity.
3499 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3500 from argc if argc was 0 initially.
3502 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3503 in generation of libpath.h.
3505 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3507 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3508 libguile from 2 to 3.
3510 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3512 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3514 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3516 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3517 scm_set_port_column_x, scm_port_filename,
3518 scm_set_port_filename_x): Removed optional arguments. Added
3519 proper argument checking.
3521 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3522 stack size in machine words.
3524 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3525 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3526 to Ole Myren Röhne.)
3528 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3530 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3531 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3533 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3536 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3537 procedure apply: Copy argument lists before pushing them unto the
3538 environment so that the environment won't get mutated due to
3539 manipulation of procedure arguments. This should perhaps be
3540 regarded as a temporary solution until someone finds a more
3541 efficient one. (Thanks to Maciej Stachowiak.)
3543 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3545 * script.c (scm_compile_shell_switches): Use "guile" as default
3546 zero arg if argc is NULL.
3548 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3550 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3551 is zero. (Thanks to Dirk Herrmann.)
3553 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3555 * ports.c (scm_add_to_port_table): First line is now line 0
3556 (was 1). (Interface changed according to suggestion by Per
3559 * backtrace.c (display_header): Add 1 to line and column numbers
3560 when presenting them to the user.
3562 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3563 from debug.c --> eval.c
3565 * eval.h, eval.c (scm_eval_options_interface): New options
3567 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3568 i.e. stacks for new threads.
3570 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3572 * eval.c (unsafe_setjmp): Removed with #if 0.
3574 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3577 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3578 to avoid compiler warnings.
3580 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3582 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3584 * throw.c (handler_message): Print message on current error port
3585 instead of default error port. (Thanks to Maciej Stachowiak.)
3587 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3589 * ports.c (scm_add_to_port_table): allocate in units of
3590 struct scm_port_table *, not struct scm_port_table.
3591 * posix.c (scm_close_pipe): remove the port from the port table
3593 Thanks to Rob Engle for both fixes.
3595 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3597 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3598 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3600 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3602 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3604 * backtrace.c (display_error_body, display_backtrace_body),
3605 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3606 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3607 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3608 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3611 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3612 don't receive the jmpbuf arg anylonger.
3613 (scm_catch): Don't accept a #f tag.
3614 (scm_throw): Check that key is a symbol.
3615 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3617 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3619 * async.c (async_pending): Removed declaration.
3621 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3623 * dynwind.c (scm_wind_chain): New debug function.
3625 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3626 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3627 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3628 extra layer of functions around the body and handler of a thread.
3629 This extra layer makes sure that the handler is called in the
3630 dynamic context of the surround (= empty dynwind list), but under
3631 the *dynamic root* of the body. We can not use the dynamic root
3632 of the surround since that root belongs to another thread => stack
3633 is not handled correctly. It may seem ugly to use this extra
3634 layer, but the extra cost in terms of execution time is really
3635 negligible compared to the total amount of time required to create
3636 a thread, and it would reduce maintainability to duplicate the
3637 crucial and complicated steps performed by cwdr.
3639 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3640 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3641 get re-enabled. The important effect of this is that interrupts
3642 are blocked during thread switching so that thread data structures
3643 don't risk getting messed up by an unfortunate signal.
3644 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3645 seems to do more aggressive optimization which actually move
3646 instructions around in these macros in a fatal way. Therefore:
3647 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3648 just superstitious...)
3649 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3650 This macro should be used instead of SCM_ASYNC_TICK since the
3651 latter doesn't do context switches any more.
3653 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3654 instead of SCM_ASYNC_TICK.
3656 * coop.c, iselect.c: Since thread switches are now performed with
3657 interrupts masked, we can't use the old mechanism of delivering
3658 signals immediately when they arrive. Signals must instead be
3659 delivered when the asyncs run *after* the end of the critical
3660 section in scm_internal_select. But this also means after context
3661 switch so that the signal will be delivered to a different thread.
3662 To avoid this, I have changed the protocol of
3663 coop_wait_for_runnable_thread and friends so that they are allowed
3664 to return the original thread. So, if a signal arrives during
3665 scm_internal_select, we won't any longer be forced do a context
3666 switch, but can remain in the same thread and deliver the signal
3669 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3670 scm_asyncs_pending and made it global.
3672 * iselect.c: Small fixes.
3674 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3675 coop_condition_variable_init, coop_condition_variable_wait,
3676 coop_condition_variable_signal): Changed return type from `void'
3677 to `int'. This is to adhere closer to the pthreads interface.
3678 This, in turn, is part of an attempt to provide C versions of the
3679 mutex and condition variable primitives which can be part of a
3680 frontend to COOP or pthreads.
3682 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3683 coop_condition_variable_destroy): New functions.
3685 * coop-threads.c (scm_wait_condition_variable): Use
3686 coop_condition_variable_wait_mutex.
3688 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3689 Definitions moved to coop-defs.h.
3691 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3692 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3693 scm_cond_destroy): New C interface to mutecis and cond vars.
3695 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3697 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3699 * iselect.c: Now several threads can wait on the same file
3700 descriptor. The behaviour is compatible with OS select: All
3701 threads waiting for the fd return with the same status.
3703 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3705 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3706 Can spawn a thread from application C code.
3708 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3710 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3711 gh_doubles2scm): New functions.
3713 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3715 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3716 commented-out version of gh_eval_str()
3718 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3720 * socket.c (scm_bind): free soka after use.
3722 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3724 * stime.c (tzvar): new variable.
3725 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3726 avoid memory leaks when allocating.
3728 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3730 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3733 * gc.c, tags.h: Doc fixes.
3735 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3737 * eval.c (macro-eval!): Removed. This function was a design bug.
3738 It allowed memoized code to leak out to the scheme level. Most
3739 things that you could do with `macro-eval!' can be done with
3742 1997-12-20 Tim Pierce <twp@skepsis.com>
3744 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3745 scm_fgets now depends on ftell(3) to know how many bytes were
3748 1997-12-15 Tim Pierce <twp@skepsis.com>
3750 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3751 dealing with strings.
3753 1997-12-13 Tim Pierce <twp@skepsis.com>
3755 Make %read-line more suitable for implementing read-line efficiently.
3756 * ioext.c (scm_read_line): Strip the terminating newline from a
3757 string, and return a cons of the string and its terminator.
3759 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3760 of the string that is read is stored in this memory location.
3761 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3762 * genio.c, genio.h (scm_do_read_line): Update caller.
3763 * ports.h (scm_ptobfuns): Update typedef.
3764 * fports.c (scm_fptob, scm_pipob): Update struct.
3766 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3768 * filesys.c (set_element): Return file descriptor.
3769 (fill_select_type): Return the highest file descriptor.
3770 (scm_select): Tell select about the highest file descriptor. On
3771 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3772 Therefore the extra overhead for calculating the maximum fd seems
3773 to be more than compensated. Is this correct? In any case,
3774 scm_internal_select will be much faster with this info.
3775 (scm_select, fill_select_type, set_element): Don't accept any kind
3776 of object in the file descriptor list or vector.
3778 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3780 * iselect.c (finalize_fd_sets): Bugfix.
3782 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3784 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3785 when using scm_internal_select (since we might switch to another
3788 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3790 * simpos.c (scm_system): always define: use sysmissing if not
3791 available. Check for HAVE_SYSTEM instead of _Windows (does
3792 Windows lack system or does it have an unusable one?).
3793 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3794 Let the argument be optional: if not supplied, call system(NULL).
3796 * ports.c (scm_close_port): relax the type check from OPPORTP to
3797 PORTP; closing a closed port is allowed.
3799 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3801 * fports.c (scm_fgets): Return if the last char in a chunk is
3802 newline. When fgets returns a string whose length is `size-1', it
3803 is ambiguous whether a whole line was retrieved, so we must check
3804 explicitly whether a line terminator is present.
3806 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3808 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3809 before taking the CDR. (Thanks to Harald Meland.)
3811 * filesys.c (scm_stat): Slightly optimized.
3813 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3815 * ports.c (scm_close_port): Make sure the port is open before
3818 * guile-snarf.in: Pass args through to gcc in a way that preserves
3819 whitespace boundaries. (Thanks to Greg Badros.)
3821 1997-12-02 Tim Pierce <twp@skepsis.com>
3823 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3824 statement. (Thanks to Doug Evans for pointing this out.)
3826 1997-12-01 Tim Pierce <twp@skepsis.com>
3828 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3830 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3832 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3833 errno macro expansion of this field name. (errno is a C
3834 preprocessor macro on some systems.)
3836 1997-11-29 Tim Pierce <twp@skepsis.com>
3838 * iselect.c: Doc fix.
3840 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3842 * init.c (scm_start_stack): Removed initialization of
3843 scm_the_last_stack_var.
3845 * backtrace.h: Declare scm_the_last_stack_var.
3847 * backtrace.c: Define scm_the_last_stack_var.
3849 * root.c (mark_root): Don't mark the_last_stack_var.
3851 * root.h (scm_root_state): Removed the_last_stack_var.
3853 * throw.c: Added #include "fluids.h"
3854 (ss_handler): `the-last-stack' is now a fluid.
3856 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3857 --> the_last_stack_fluid.
3859 * backtrace.c: Added #include "fluids.h"
3860 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3861 (scm_backtrace): `the-last-stack' is now a fluid.
3863 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3864 after scm_init_fluids.
3866 1997-11-28 Tim Pierce <twp@skepsis.com>
3868 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3870 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3871 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3873 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3875 * iselect.c (coop_next_runnable_thread,
3876 coop_wait_for_runnable_thread): Disable interrupts so that no
3877 async is executed before a potential error_revive.
3878 (scm_internal_select): Disable interrupts during the parts of the
3879 code which manipulate the sleep queue and the file descriptors.
3881 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3883 * Makefile.am: Added iselect.c and iselect.h.
3885 * coop.c (coop_qinit): Initialize fields used by
3886 scm_internal_select.
3887 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3888 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3889 replacement in iselect.c.
3890 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3891 coop_join): If GUILE_ISELECT enabled, use
3892 coop_wait_for_runnable_thread instead of
3893 coop_next_runnable_thread.
3894 (usleep, sleep): New replacements for system functions if
3895 GUILE_ISELECT is enabled.
3897 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3899 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3901 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3902 iselect.h. Implement Scheme level `select' using
3903 scm_internal_select. (See NEWS.)
3905 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3907 * init.c: Call scm_init_iselect.
3909 * iselect.h, iselect.c: New files. Implements
3910 scm_internal_select. (See NEWS.)
3912 1997-11-27 Tim Pierce <twp@skepsis.com>
3914 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3915 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3916 and scm_must_free, since ultimately the string returned will be copied
3917 by scm_makfrom0str anyway. Also, read any characters that may have
3918 been pushed onto the port with scm_ungetc.
3919 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3920 * ioext.c (scm_read_line): Free string after Guilifying it.
3921 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
3923 1997-11-26 Anthony Green <green@hoser.cygnus.com>
3925 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
3927 * gh.h: Safely wrap prototypes for c++ usage.
3929 1997-11-25 Mark Galassi <rosalia@cygnus.com>
3931 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3932 gh_repl (argc, argv).
3934 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3936 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3937 and to invoke scm_shell().
3938 (gh_launch_pad): took out the loading of boot-9.scm from here,
3939 since it is probably best to let the user control that. In fact,
3940 gh_repl() now invokes scm_shell() which does that.
3942 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3944 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3947 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
3949 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
3950 yesterday's underscore patch. (Thanks to Marius Vollmer for
3953 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
3955 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
3956 DLSYM_ADDS_USCORE is not defined.
3958 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
3960 * gh_data.c (gh_uniform_vector_length):
3961 (gh_uniform_vector_ref): started implementing the uniform types in
3964 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
3966 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3967 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3969 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3971 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
3972 configure.in was changed).
3974 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
3976 * Makefile.am (modinclude_HEADERS): Include readline.h here.
3977 * Makefile.in: Regenerated.
3979 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
3981 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
3982 OPORT is an `open' port, not an output port.
3984 * filesys.c (scm_close, set_element, get_element, scm_chown,
3985 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
3986 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
3987 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
3988 scm_close_port, scm_port_line, scm_set_port_line_x,
3989 scm_port_column, scm_set_port_column_x, scm_port_filename,
3990 scm_set_port_filename_x, scm_port_mode,
3991 scm_close_all_ports_except, scm_set_current_output_port,
3992 scm_set_current_error_port): Likewise
3993 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
3994 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
3996 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
3997 * backtrace.c (display_backtrace_body): Likewise
3998 * fports (scm_setvbuf): Likewise
3999 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
4000 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
4001 scm_getpeername, scm_send, scm_sendto): Likewise
4002 * unif.c (scm_uniform_array_write): Likewise
4004 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
4006 Minor problems with substring-related tag changes.
4007 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
4008 exactly what we want to leave in to detect substrings.
4009 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
4010 * tags.h: Fix diagrams and comments describing the S tag bit;
4011 remove vestigial remarks about the D tag bit.
4012 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
4013 * strings.c: Formatting tweaks.
4015 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
4016 variable first; then SCHEME_LOAD_PATH, with a warning message.
4017 (scm_parse_path): New function.
4018 * script.c: Doc fixes.
4020 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
4022 Readline support, from Daniel Risacher.
4023 * readline.c, readline.h: New files.
4024 * init.c: #include "readline.h".
4025 (scm_boot_guile_1): Call scm_init_readline, if we have it.
4026 * Makefile.am (libguile_la_SOURCES): Include readline.c.
4027 * Makefile.in: Regenerated.
4028 * scmconfig.h.in: Regenerated, after change to ../configure.
4030 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4032 * gh.h: gh_vector_set -> gh_vector_set_x
4034 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4036 * gh_data.c (gh_vector_set_x): changed name to make it consistent
4037 with the ! -> _x mapping when going from Scheme to C.
4039 1997-10-19 Mark Galassi <rosalia@cygnus.com>
4041 * gh.h (gh_reverse):
4049 (gh_assoc): added these gh_ functions implemented as macros.
4051 * gh_predicates.c (gh_null_p):
4052 (gh_string_equal_p): added these two missing predicates.
4054 * gh_list.c (gh_append):
4059 (gh_set_cdr_x): added these routines as I go through and try to
4060 complete the picture R4RS functions that should be mirrored in the
4063 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4065 * tags.h (scm_tc7_substring): Changed the comment and code to
4066 conform with the changes below. Folks! We have suddenly two new
4067 free tc7 codes!!! Jummy, jummy!
4069 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
4071 * Makefile.in: Rebuilt.

4092 (scm_tc7_mb_string): Removed.
4093 (scm_tc7_mb_substring): Removed.

4097 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
4098 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
4100 Don't include "mbstrings.h".
4101 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
4102 (SCM_SYMBOL_SLOTS): Define as 4.
4103 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
4104 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
4105 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,

4124 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
4125 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
4127 1997-10-12 Mark Galassi <rosalia@cygnus.com>
4129 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
4131 * gh_test_c.c (c_vector_test): some improvements on the vector
4134 * gh.h (gh_vector): this used to exist but do the wrong thing.
4135 Now it (almost) does the right thing, though it takes a list
4136 instead of the individual arguments. I need to see how it could
4138 (gh_list_to_vector): added this function as a macro. Corresponds
4139 to Scheme's (list->vector ...).
4140 (gh_vector_to_list): added this function as a macro. Corresponds
4141 to Scheme's (vector->list ...).
4143 * gh_data.c (gh_vector_ref): renamed from gh_vref to
4144 gh_vector_ref, so that it resembles the Scheme routines more.
4145 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
4146 resembles the Scheme routines more.
4147 (gh_make_vector): this used to be (stupidly) called gh_vector().
4148 This is the right name, since it does the same thing as the Scheme
4149 (make-vector ...) procedure.
4151 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
4153 * ports.h: #include "libguile/print.h"
4155 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
4156 Some indentation fixes.
4158 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
4159 longer a user field; New field: class_flags.
4161 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
4163 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
4165 * gh_data.c (gh_bool2scm): new function which replaces
4166 gh_int2scmb(), which is now tagged as obsolete.
4168 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
4170 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
4171 macros should by convention not test for NIMPness.)
4172 (SCM_COERCE_OPORT): Adjust indentation.
4174 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
4175 SCM_NIMP test before SCM_PRINT_STATE_P.
4177 * struct.c, struct.h, gc.c: Renamed:
4178 scm_struct_i_layout --> scm_vtable_index_layout
4179 scm_struct_i_vcell --> scm_vtable_index_vcell
4180 scm_struct_i_vtable --> scm_vtable_index_vtable
4181 scm_struct_i_printer --> scm_vtable_index_printer
4182 scm_struct_i_vtable_offset --> scm_vtable_offset_user
4184 * struct.c (scm_print_struct): Use new printer slot; Default
4185 printing: Also output hex code of vtable so that type identity
4186 will be indicated as well.
4187 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
4188 Removed struct_printer_var; Removed struct-vtable-offset;
4189 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
4190 vtable-offset-user): New constants.
4192 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
4193 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
4194 If this slot contains a procedure, use that to print structures of
4195 the type represented by this vtable.
4197 * print.c (scm_iprin1): Don't print arguments of macro
4198 transformers. (They are always: exp env.); Bugfix: Unmemoize
4199 transformer source with correct environment.
4201 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
4203 Streamlining of call-with-dynamic-root:
4205 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
4206 there is now only one catch.
4207 (cwdr_outer_body): Removed.
4208 (cwdr_handler): New function.
4209 (scm_internal_cwdr): New function to perform the function of cwdr
4210 but take args that are more useful to C code. Also, the handler
4211 is now invoked *outside* of the new dynamic root, like the docs
4212 say. We no longer have to catch absolutely all errors, the caller
4213 is responsible for using a handler that does not throw, if he
4215 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4216 * root.h (scm_internal_cwdr): New prototype.
4218 Even more but risky streamlining:
4220 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4221 allocation of the jumpbuf of a root continuation. The changes
4222 below are controlled by it. They are now deactivated.
4223 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4224 the JMPBUF of the scm_rootcont to NULL before returning.
4226 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4227 when they are non-NULL.
4228 (scm_gc_mark): Likewise, mark only when non-NULL.
4230 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
4231 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
4233 * gc.c (scm_done_malloc): New function.
4234 gc.h (scm_done_malloc): New prototype.
4236 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
4237 (struct scm_print_state) [revealed]: New field.

4239 type checking purposes.
4240 (scm_valid_oport_value_p): New prototype.
4242 * print.c (scm_valid_oport_value_p): New function to check whether
4243 a certain value is acceptable as a port argument.
4244 (scm_print_state_vtable): New variable.
4245 (scm_free_print_state): Set `revealed' field to false.
4246 (scm_iprin1): Call user supplied closure printer with
4247 scm_printer_apply. Print in the traditional way when there isn't
4248 one or when it returns #f.
4249 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4250 Accept a port/print-state pair in addition to just a port.
4251 (scm_prin1): Don't return the print_state to the pool when it has
4253 (scm_printer_apply): Set `revealed' field of print_state to true.
4254 (scm_init_print): Set scm_print_state_vtable.
4255 (print_state_fluid, print_state_fluid_num): Removed.
4257 * throw.h (scm_handle_by_proc_catching_all): New prototype
4258 throw.c (scm_handle_by_proc_catching_all): New function
4260 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
4262 * Makefile.in: Regenerated with automake 1.2c.
4264 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
4266 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
4267 was looping endlessly.
4269 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
4271 * strports.c (scm_eval_string): Don't close the port.
4273 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
4274 former returns a nice normal integer. (Thanks to Daniel
4277 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
4279 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
4280 makefile variable as a build parameter called LIBS. The
4281 build-guile program will use this, for the time being.
4282 * Makefile.in: Regenerated.
4284 Thanks to Shiro Kawai:
4285 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
4286 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
4289 * Makefile.in: Regenerated with automake 1.2a.
4291 * script.c (scm_compile_shell_switches): If we hit the -c or --
4292 arguments, don't set the car of (command-line) to scm_usage_name,
4293 the prettified name of the guile executable; give it the full
4294 path, the way shells usually handle $0.
4296 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4298 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
4299 Scheme-level name `array-map' and renamed `serial-array-map' to
4300 `serial-array-map!'.
4302 * backtrace.c: Introduced exception handlers which now enclose
4303 `display-error' and `display-backtrace' so that error reporting
4304 won't get into infinite loops if an error occurs during displaying
4305 of the error. This can very easily happen with user supplied
4306 print call-back routines.
4308 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4310 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
4311 the names `serial-array-map' and `array-map' should be removed.)
4313 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
4315 * init.c (scm_boot_guile_1): Added scm_init_objects ().
4316 Added #include "objects.h"
4318 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
4319 Add #include "feature.h".
4321 * Makefile.am (libguile_la_SOURCES): Added objects.c.
4322 (modinclude_HEADERS): Added objects.h.
4324 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
4325 This test is needed at many places in the code and should be
4326 abstracted. (Motivated by the need of this test in libguiletk.)
4328 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
4329 (scm_eval_string), load.c (scm_primitive_load,
4330 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
4331 Use SCM_EOF_OBJECT_P.
4333 * eval.c (scm_init_eval): Add feature `delay'.
4335 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4337 * scmhob.h: Removed.
4339 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4341 * list.h (SCM_LISTn): New macros. Make list creation in C code
4342 prettier. The idea comes from STk.
4344 * sequences.h, sequences.c, append.h, append.c: Removed. These
4345 files implemented non-R4RS operations which would encourage
4346 non-portable programming style and less easy-to-read code.
4348 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
4351 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
4352 sequences.h, #include append.h.
4354 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
4357 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
4359 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
4361 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
4363 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4365 * eval.c: Added #include "objects.h"
4367 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
4370 * smob.c (scm_smob_prehistory): Create two objectsmobs with
4371 adjacent smob numbers.
4373 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4375 * procprop.h: Added declaration of scm_i_inner_name.
4377 * gsubr.c: New global symbol scm_i_inner_name.
4379 * debug.c (scm_procedure_name): Try procedure property
4380 `inner-name' if `name' fails.
4382 * print.c (scm_iprin1): Use scm_macro_name.
4384 * eval.c (scm_m_define): Give names to macros as well; Only the
4385 first top-level definition gives a procedure/macro a name.
4386 Otherwise confusing names can turn up in backtraces.
4387 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4388 `name'; Give names to macros as well.
4390 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4391 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4394 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4396 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4398 (prinmacro): Removed. The code has been moved/merged into print.c
4399 in order to decrease code redundancy. We want macros to print in
4400 a way equivalent to procedures, and it would be silly to duplicate
4401 the required code. (We don't want to maintain two places.)
4402 (macrosmob): Print field is now a NULL pointer.
4404 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4405 scm_macro_transformer): New prototypes.
4406 (scm_tc16_macro): Declared.
4408 * print.c (scm_iprin1): Added code for printing of macros. Macros
4409 are now printed in a way equivalent to procedures.
4411 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4413 * procs.h (scm_closure_p): Added declaration.
4415 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4417 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4418 Shouldn't pass "heap" as the subr name.
4420 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4422 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4423 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4424 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4425 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4426 SCM_BOOL_T. Any non-false value is true.
4428 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4430 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4431 scm_gensym): Added prototypes.
4433 * symbols.c (scm_gensym): New function. This will speed up
4434 certain types of applications (such as macro systems) which
4435 generate lots of symbols.
4437 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4439 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4441 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4443 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4444 specifier, since (2) or (2 . 3) would cause SEGV.
4445 (scm_transpose_array): more argument checking fixes.
4447 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4449 * Makefile.in: Regenerated.
4451 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4453 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4455 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4457 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4459 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4461 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4462 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4465 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4466 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4467 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
4468 scm_array_p, scm_array_rank, scm_array_dimensions,
4469 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
4470 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
4471 scm_array_prototype): Added case scm_tc7_wvect.
4473 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
4475 * errno.h: prototype for scm_strerror.
4476 * error.c (scm_strerror): new procedure.
4478 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4480 * list.c (scm_list_append_x): Allow non-pair as last argument.
4481 This is consistent with the R4RS append and is probably the
4482 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4484 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4486 * stime.h: prototype for scm_times.
4487 * stime.c (scm_times): new procedure.
4488 * ioext.c (scm_fseek): if the first argument is a file descriptor
4490 (scm_ftell): if the first argument is a file descriptor call lseek
4492 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
4493 * filesys.c (scm_chmod): if the first argument is a file descriptor,
4495 (scm_chown): if the first argument is a port or file descriptor,
4497 (scm_truncate_file): new procedure.
4498 Add DEFER/ALLOW INTS to a few other procedures.
4499 (scm_fsync): new procedure.
4500 (scm_open_fdes): new procedure.
4501 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
4503 (scm_fcntl): the first argument can now be a file descriptor. The
4504 third argument is now optional.
4506 * posix.c (scm_execl, scm_execlp): make the filename argument
4507 compulsory, since omitting it causes SEGV.
4508 (scm_sync): return unspecified instead of #f.
4509 (scm_execle): new procedure.
4510 (environ_list_to_c): new procedure.
4511 (scm_environ): use environ_list_to_c. disable interrupts.

4517 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4518 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4519 argument to SCM_ASSERT. Furthermore, the name of the function
4520 should be passed as first argument when signalling
4521 SCM_WNA. (Thanks to Thomas Morgan)
4523 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4524 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4525 dispatches on the number of actual args has a default case
4526 reporting an internal error. This is a vestige from a version
4527 that mallocated a SCM vector to hold the arguments. In the
4528 current version this check is too late: if it ever happens we will
4529 have already overstepped the bounds of the array.
4531 Also, the patch [...] adds a check for too many actual arguments."
4533 mdj: Removed check for "internal programming error".
4535 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4537 * gh_io.c (gh_write): New function.

4552 fold in the functionality of scm_primitive_dup.
4553 (scm_primitive_dup): deleted.
4555 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>

4580 definitions to help with calling printer functions written in
4582 * print.h (scm_printer_apply): New prototype.

4595 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
4596 SCM_ASSERT: arg comes before pos.
4598 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4600 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
4601 to a list of length zero correctly.
4603 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

4621 * ioext.c (scm_primitive_dup2): return the new file descriptor
4622 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
4624 (scm_fdopen): bug fix: don't try to make port unbuffered until its
4625 stream has been set.
4626 (scm_duplicate_port): deleted, there's now an implementation in
4628 (scm_primitive_dup2): do nothing if newfd == oldfd.
4630 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
4632 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

4652 * filesys.h: scm_close prototype.
4653 * filesys.c (scm_close): new procedure, can close file descriptors
4654 and ports (scsh compatible).

4679 data. (dynl_smob): Use it.
4680 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4681 the dynamic object data below the linking of the object to avoid
4682 memory leak when the linking code throws an error. Now the code
4683 leaks a whole dynamically linked library when must_malloc throws,
4684 but that should be much less likely.
4686 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4688 Changes to compile under gnu-win32, from Marcus Daniels:

4704 (scm_setpwent): For setpwent.
4705 (scm_setegid): For setegid.
4706 * net_db.c (scm_inet_netof): Don't include unless support

4726 think this is left over from the (eq? '() #f) days.
4728 * read.c (recsexpr): Give this a dummy definition if
4729 DEBUG_EXTENSIONS isn't #defined.
4731 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
4733 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

4744 alloca.lo will be included in @LIBLOBJS@. Something better than
4745 this should be possible.
4746 * Makefile.in: Regenerated.
4748 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4750 * simpos.h: prototype for scm_primitive_exit.
4751 * simpos.c (scm_primitive_exit): new procedure, terminates the

4756 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
4757 argument and logior its components together, so the user doesn't
4758 have to do this explicitly. Also, if regexp/basic is supplied, then
4759 turn off REG_EXTENDED.
4760 (scm_init_regex_posix): New regexp/basic symbol.
4761 (REG_BASIC): #define this if it is not already present.

4780 flag; I don't think we support it.
4781 (scm_make_regexp): Make sure the user doesn't pass the
4784 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
4786 (scm_init_regex_posix): Define constants for the REG_mumble flags;

4804 * root.c: Establish a reliable catch-all handler for the new root.
4805 After all the Scheme handler function might signal an error too,
4806 and we don't want to lose that.
4807 (cwdr_inner_body): Renamed from cwdr_body.
4808 (cwdr_outer_body): New function, to establish the user's handler,
4809 and pass control to cwdr_inner_body.
4810 (cwdr): Establish the reliable catch-all handler here, and pass
4811 control to cwdr_outer_body.
4812 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
4813 the user's handler through to cwdr_outer_body.

4820 across this. Only works on GCC. Otherwise, we hope for the best.
4821 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4822 the feeling that real thread systems will not need this...
4824 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4826 Try to detect when people are using one version of libguile and a

4838 primitive definitions under their Scheme names.
4840 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4841 1:2. Helps avoid confusion between installed and uninstalled libs.
4843 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
4846 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
4847 backslash from definition; this should be used like: GDB_INTERFACE;
4849 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4851 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
4852 new port unbuffered until its stream has been set.
4854 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
4856 * ports.h: new prototype.

4866 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4868 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
4869 argument plain char *.
4870 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
4872 * tag.c (scm_tag): Remove unreachable statement.
4873 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4874 top of the word, it should be unsigned.
4876 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4877 is defined, to avoid warnings; it's only used in the
4878 conflict-checking code. Which might go away anyway.
4879 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4880 conditionals; put the label definition in an #if too, to stifle
4883 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4884 ChangeLog-threads in the distribution.
4885 * Makefile.in: Regenerated.

4890 whitespace between lexical tokens (which munges the `%%%' snarf
4893 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4895 * load.c (scm_init_load_path): Append $(datadir)/guile to
4896 %load-path, so modules do not have to be installed in Guile's
4897 current version directory.
4899 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
4901 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
4902 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
4903 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
4904 call the sysdep functions with deferred ints.

4906 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
4907 deferred interrupts and insert SCM_ALLOW_INTS before throwing an

4925 condition during lookup (when using threads).
4926 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4927 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4930 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4932 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4933 supplied. (Change from Tim Pierce.)
4935 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4937 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4938 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4939 default and not `()'. `#f' is the canonical non-value in Scheme,
4942 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4944 * struct.c (struct_printer): New variable that holds a handle on
4945 the Scheme variable *struct-printer*. This variable can be set by
4946 Scheme code to override the printing of structures.
4947 (scm_print_struct): If struct_printer is set, call it. If it is
4948 not set, or returns #f, print the structure in the old fashion.
4949 Include "eval.h" for scm_apply.
4951 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4953 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4954 scm_struct_i_n_words to get the number of fields, not
4955 -scm_struct_n_extra_words.
4957 On the route to fancier struct printing:
4958 * struct.c (scm_print_struct): New function to print a structure.
4959 Include "genio.h" to support it. This function doesn't do
4960 anything interesting right now, but I think it should be here
4962 * struct.h: Include "print.h" and add prototype for
4964 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4965 print structures ourself.
4967 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4969 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
4970 before applying the handler in case it doesn't return.
4972 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
4974 * scmsigs.h, async.h: updated.
4976 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
4979 * posix.c (scm_uname): interpret only negative values as an error.
4980 Solaris normally returns a positive value.
4982 * script.c (scm_compile_shell_switches): if we are not going into
4983 an interactive repl, set scm_mask_ints to zero so that asyncs can
4986 * simpos.c (scm_system): don't ignore/unignore signals around
4989 * posix.c (scm_open_pipe): don't ignore/unignore signals around
4992 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
4993 done in boot-9.scm instead.
4995 * scmsigs.c, async.c: Major rewriting of signal handling code.
4996 (scm_sigaction): new procedure.
4997 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
4999 (scm_raise): return unspecified, throw error on failure.
5001 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5003 * regex-posix.c (scm_init_regex_posix): Register the "regex"
5004 feature, to help boot-9.scm decide whether to import the regex
5007 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5009 * eval.c: Include scmconfig.h at the beginning of the file so that
5010 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
5013 * regex-posix.c: #include "_scm.h" before conditionally #including
5014 <regex.h>; the former defines HAVE_REGCOMP.
5016 * regex-posix.c: #include <regex.h> conditionally, so the file is
5017 CPP'able (for dependency scanning) even on systems that don't have
5020 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5022 Add new R4RS-compliant syntax for keywords.
5023 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
5024 regardless of the setting of the `keywords' read option.
5025 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
5026 can be re-read no matter what the setting of the `keywords' read
5029 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
5031 Add support for POSIX regular expressions.
5033 * regex-posix.c, regex-posix.h: New files. (Some code
5034 is taken liberally from rx/rgx.c in the old Guile dist.)
5036 * init.c: Include regex-posix.h.
5037 (scm_boot_guile_1): Call scm_init_regex_posix.
5039 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
5040 Add regex-posix.[ch] sources.
5041 * Makefile.in: Regenerated.
5043 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
5044 to do this automatically? It didn't for me, bleh.)
5046 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
5048 * fports.c (print_pipe_port): New function.
5049 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
5050 latter doesn't even take the right arguments.
5052 * Makefile.am: Increment shared lib revision number. I think
5053 sometimes the uninstalled Guile finds the installed shared lib;
5054 Gord says doing this might help. As things turned out, I can't
5055 say whether it does.
5056 * Makefile.in: Regenerated.
5058 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
5059 passing it as the closure argument to scm_boot_guile. (Bill
5062 * ports.c (print_void_port, putc_void_port, puts_void_port,
5063 write_void_port, flush_void_port, getc_void_port, close_void_port,
5064 noop0): Use ANSI prototypes instead of K&R declarations, so the
5065 initialization of void_port_ptob gets aggressively type-checked.
5066 Fix arguments of print_void_port and write_void_port. (Bill

5100 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
5102 * script.c (scm_find_executable): Use prototype-style definition
5103 here; apparently it's not quite right to have const in a prototype
5104 and then use a K&R declaration. I wonder if stuff like this will
5105 go away if we compile with -Wrequire-prototypes, or whatever that
5106 is... (Bernard URBAN)
5108 * scmhob.h: New text from Bernard URBAN.
5110 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5112 * script.c: Don't #define const on hpux. Configure takes care of
5113 this. (Thanks to Larry Schwimmer.)
5115 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5116 decide whether to #include <unistd.h>, instead of listing a bunch
5117 of systems. Don't #include stdio twice. Removed dyked-out
5118 definition of scm_find_impl_file.
5120 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5122 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5123 library version info to 1:0.
5124 * Makefile.in: Regenerated.
5126 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

5130 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5131 throw.c: Update copyright years; these files have been worked on
5132 significantly in 1997, but only had copyright years for 1996.
5133 Also, change name of copyright holder on some from Mikael
5134 Djurfeldt to Free Software Foundation; he has signed papers
5135 assigning the changes to the FSF.
5137 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5138 reason not to give the user the option.
5140 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5141 Return #f on end-of-file when scanning table (i.e. when called
5142 with no arguments). Try to catch errors, when we can.
5143 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5145 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5146 external declarations. These are useful.
5148 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5150 * posix.c: don't include <sys/select.h> or define macros for
5151 select, since they were not used in this file.
5153 * filesys.c (scm_select): make the fifth parameter microseconds,
5154 not milliseconds. let the fourth parameter be either a real value
5155 or an integer or #f. The first, second and third arguments can
5156 now be vectors: the type of the corresponding return set will be
5158 (set_element, get_element): new static procedures.
5160 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5162 * strports.c (scm_eval_string): New function.
5163 (scm_eval_0str): Trivially re-implemented in terms of
5165 * strports.h (scm_eval_string): New extern decl.
5167 * net_db.c (h_errno): Add extern decl for this.
5169 * fports.c (local_pclose): New function.
5170 (scm_pipob): Use it in the initializer here.
5173 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5174 Use a meaningful error message when signalling an error. For
5175 this, scm_gethost must check h_errno rather than errno.
5177 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5179 * Makefile.in: Regenerated, using automake-1.1p.
5181 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5183 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5184 not SCM_UNSPECIFIED.
5186 * script.c (scm_compile_shell_switches): don't append (quit) if
5188 (scm_shell): call scm_exit_status and exit on the result of the
5191 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5193 Ensure that shared substrings are handled properly when passed to
5194 a system call or other foreign function. Many thanks to Tim
5196 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5197 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5198 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5199 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
5200 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
5201 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
5202 (scm_display_error_message): use RO macros when strings may be RO.
5203 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
5204 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
5205 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

5209 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
5210 scm_strftime), vports.c (scm_make_soft_port): use
5211 SCM_COERCE_SUBSTR to make sure shared substrings are
5214 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5216 * error.c (scm_error): Add newline to error message.
5218 * init.c (scm_init_standard_ports): Doc fix.
5220 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5222 * dynl-shl.c: Completely replaced with new code from Bernard
5225 * script.c (scm_ice_9_already_loaded): New variable.
5226 (scm_compile_shell_switches): Use it.
5228 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5230 * filesys.c (scm_input_waiting_p): add missing third argument to
5233 * stime.c (scm_localtime): copy the result of localtime before
5234 calling gmtime in case they share a buffer.
5235 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5238 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5240 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5242 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5244 * Makefile.am (check-local): New target, which causes 'make check'
5245 to run gh_test_c and gh_test_repl, with some trivial input.
5246 * Makefile.in: Rgnrtd.
5248 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5250 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5253 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
5255 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
5256 sure how this was supposed to work.
5257 (scm_async_click): don't send SCM_TICK_SIGNAL.
5258 (scm_init_async): don't initialize %tick-thunk.
5260 * the following change doesn't affect the Scheme interface:
5261 gc-thunk is called at the end of garbage collection. however it's
5262 no longer implemented by pretending it's a signal.
5264 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
5265 system async corresponding to scm_gc_thunk.
5266 * async.h: declare scm_gc_async.
5267 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
5268 gc-thunk directly, instead of going through a signal handler.
5269 (scm_gc_async): new variable, points to the GC system-async.
5270 (scm_init_async): save the GC async as scm_gc_async instead
5271 of using system_signal_asyncs.
5272 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
5274 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
5276 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
5277 Don't screw up if we're interrupted.
5278 * Makefile.in: Regeneradet.
5280 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
5282 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
5284 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
5285 we're not using AM_INIT_GUILE_MODULE any more.
5286 * Makefile.in: Reneregated.
5288 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5290 Functions for finding variable bindings, grace à Tim Pierce.
5291 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
5292 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
5294 Get 'make dist' to work again.
5295 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
5296 * Makefile.in: Regenerated, like a surry without a fringe on top.
5298 Changes for reduced Guile distribution: one configure script,
5300 * configure.in, configure: Removed.
5301 * acconfig.h, acinclude.m4: Moved to parent directory, where the
5302 real configure script lives.
5303 * Makefile.in, scmconfig.h.in: Regenerated.
5305 * init.c: #include "script.h", to get prototype for script.c's
5308 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
5310 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
5311 scm_must_malloc, not raw malloc.
5313 * script.c (scm_compile_shell_switches): Dyke out debugging output
5316 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5318 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
5320 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
5321 system has them. Hope this is safe. Previously
5322 sys/timeb.h was included if HAVE_FTIME was defined or if
5323 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
5324 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
5326 * ioext.c (scm_setfileno): add missing third argument to
5327 scm_misc_error call.
5329 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
5331 * eq.c (scm_equal_p): Correctly compare strings of different
5332 varieties. (Thanks to Tim Pierce.)
5334 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
5336 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
5337 #! block comment must occur on a line all by itself.
5339 Move most of the guts of shell command processing into libguile,
5340 so guile.c can be very small (and eventuallly auto-generated. (I
5341 mean, generated mechanically, not self-generated. Hmm.))
5342 * guile.c, script.c, script.h: New source files.
5343 * init.c (scm_boot_guile_1): Call scm_init_script.
5344 * libguile.h: #include "script.h".
5345 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
5346 targets, for new executable.
5347 (libguile_la_SOURCES): Mention script.c.
5348 (modinclude_HEADERS): Add script.h.
5349 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
5350 not dynamic linking is enabled. This is because we're generating
5351 executables now. Move CY_AC_WITH_THREADS call after those, so the
5352 values of cy_cv_threads_libs captures the libs chosen above.
5353 * Makefile.in, configure, aclocal.m4: Regenerated.
5355 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
5356 We don't maintain this interface any more, and it just confuses
5359 * alloca.c: #include <scmconfig.h>, not <config.h>.
5360 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
5361 it'll get included in disties.
5363 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5365 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
5366 be distributed, because they confuse people.
5367 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
5369 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
5371 * configure.in: check for presence of gethostent (not present on
5372 OpenBSD by default).
5373 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
5374 * configure, scmconfig.h.in: Regenerated.
5376 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5378 * backtrace.c (scm_backtrace): Split message string across
5379 newlines properly. GCC is more tolerant of this than other
5382 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
5384 Merge threads directory into libguile.
5385 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5386 threads.h: New source files.
5387 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
5388 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
5390 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5391 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5392 coop-threads.c.cygnus, coop-threads.h.cygnus.
5393 * configure.in: If we're using threads, include threads.o in
5395 * _scm.h, libguile.h: threads.h lives in this directory now.
5396 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5397 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5398 currently used, but brought along for information's sake.
5399 * ChangeLog-threads: log from old 'threads' directory.
5400 * Makefile.in, configure: Rebuilt.
5402 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5404 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5407 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5409 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5411 Merge GH interface library into libguile.
5412 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
5413 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5414 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5415 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5417 (EXTRA_libguile_la_SOURCES): ... here.
5418 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5419 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5420 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5421 New variables, describing how to build the gh test programs.
5422 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5423 build the test programs, and we probably should have been linking
5424 libguile.la against them all along, to support AIX shared libs.
5425 Add cflags for threads to CFLAGS; add libs for threads to new
5426 variable THREAD_LIBS, used in Makefile.am.
5427 * ChangeLog-gh: log from old `gh' subdirectory.
5428 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5430 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5432 * acconfig.h: Undo change of Apr 9; including the definition of
5433 PACKAGE in the guile headers conflicts with applications' own
5435 * scmconfig.h.in: Regenerated.
5437 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
5439 * filesys.c (scm_fcntl): New function from Roland McGrath.
5440 (scm_init_filesys): New symbols for use with fcntl.
5441 * filesys.h: Added prototype.
5443 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
5444 when PROC is receiving no arguments.
5446 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5448 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5449 have S_IFSOCK. This is the case under Ultrix.
5451 * posix.c (scm_status_exit_val, scm_status_exit_val,
5452 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5453 Ultrix versions of WIFSTOPPED, etc., which assume that their
5454 arguments are lvalues (hmm).
5456 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5458 * eval.c: Doc fixes.
5460 * throw.c: Doc fixes; rearranged.
5462 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
5464 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
5466 * acconfig.h: Added entry for PACKAGE.
5467 * scmconfig.h.in: Regenerated.
5469 Changes to work with automake-1.1n, which has better libtool support.
5470 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5471 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5473 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5475 * Makefile.in: Rebuild.
5477 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5479 * stime.c (scm_mktime): take an optional zone argument.
5480 (scm_localtime): check putenv return value.
5481 (scm_strftime, scm_strptime): moved from posix.c. move #include
5483 stime.h, posix.h: update prototypes.
5484 (bdtime2c, setzone, restorezone): new static procedures.
5485 (scm_mktime, scm_strftime): use them.
5486 (scm_strftime): don't call mktime before strftime. Use
5487 filltime for return value.
5488 (filltime): convert NULL zname to #f.
5489 (scm_strptime): return a count of characters consumed, not
5490 the remaining string.
5492 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5494 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
5495 (scm_mktime): likewise.
5497 Uncomment localtime and mktime.
5499 * configure.in: add AC_STRUCT_TIMEZONE.
5501 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5503 * stime.c (scm_init_stime): don't define ticks/sec.
5504 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5505 return value problem and is still portable.)
5507 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5509 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5510 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5511 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5512 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5513 cpp_err_symbols.c): Corresponding changes.
5514 * Makefile.in: Regenerated.
5516 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5518 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5519 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5520 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5521 * putenv.c: new file, from sh-utils 1.12.
5523 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5524 since allocation isn't for Scheme objects.
5525 (scm_putenv): copy strings before placing in the environment.
5527 * stime.c (scm_current_time): throw an error if time returns -1,
5528 instead of returning #f.
5529 (scm_get_internal_real_time, scm_get_internal_real_time): use
5530 scm_long2num for return value instead of SCM_MAKINUM.
5532 * stime.h: prototypes updated.
5534 * stime.c (scm_time_in_msec): apparently unused, deleted.
5536 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5538 * configure.in: check for gettimeofday.
5540 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5541 which may be more usefully portable than a gettimeofday interface.
5543 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5545 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5547 * Makefile.in: Regenerated.
5549 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5551 * stime.c (filltime): recovered static procedure.
5552 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5555 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5556 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5558 * posix.c (scm_mknod): split the mode argument into type and perms
5559 arguments, like the extra fields returned by stat.
5561 * fports.c (scm_pipob): set the close, free and print procedures.
5562 (scm_close_pipe): new procedure.
5564 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5565 define them in boot-9.scm
5567 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5569 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5570 wan't defined. Don't include fd.h.
5572 * Previously fd.h was regenerated whenever configure was run,
5573 forcing a couple of files to be recompiled.
5575 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5576 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5577 Check for _fileno as well as _file.
5579 * ioext.c: don't fd.h.
5580 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5583 * Change the stratigy for getting information about errno
5584 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5585 generating lists of symbols during the build process, which will
5586 not always work, include comprehensive lists in the distribution.
5587 To help keep the lists up to date, the "check_signals" and
5588 "check_errnos" make targets can be used.
5590 * configure.in: don't check for a command to extract errno codes.
5591 * Makefile.am: update file lists, remove errnos.list and errnos.c
5592 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5593 check_errnos targets.
5594 (CLEANFILES): remove errnos.c and errnos.list, add
5595 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5596 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5597 * errnos.default: deleted.

5599 * cpp_errno.c: renamed from errnos_get.c.
5600 * cpp_err_symbols, cpp_sig_symbols: new files.
5601 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5602 * error.c (scm_init_error): #include cpp_err_symbols instead of
5604 * posix.c (scm_init_posix): don't intern signal symbols. #include
5607 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5609 * strop.c (scm_i_index): allow the lower bound to be equal to the
5610 length of the string, so a null string doesn't always give an error.
5612 * posix.h: new prototypes.
5613 * posix.c (scm_status_exit_val, scm_status_term_sig,
5614 scm_status_stop_sig): new functions, as in scsh. They break down
5615 process status values as returned by waitpid.
5617 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5619 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5620 configure doesn't know about it.
5622 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5624 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5626 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5627 which defines C variables with global linkage.
5629 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5631 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5634 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5636 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5637 has time to check why this doesn't work well with continuations.
5639 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5641 * Fix shell syntax error; some shells won't tolerate
5642 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5644 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5646 * posix.c (scm_uname): throw an error if uname fails instead
5649 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5651 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
5654 * async.c (scm_ints_disabled): definition moved from error.c.
5656 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5658 * acconfig.h: Removed PACKAGE.
5660 * scmconfig.h.in: Regenerated.
5662 * snarf.h: g++ says it's non-portable not to specify the first
5663 argument in a varargs declaration. I introduced the first
5664 argument by using preprocessor conditionals.
5666 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5668 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5669 (scm_freopen): use RO string macros for filename and modes.
5670 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
5672 * posix.c (scm_getgrgid): simplify conversion of name to C string.
5673 (scm_mknod): use RO string macros for path.
5675 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
5676 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5678 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5679 use SCM_ROSTRINGP and SCM_ROCHARS.
5681 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5683 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5686 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5687 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5688 support for byte vectors.
5690 * print.c (scm_iprin1): Limit number of vector elements printed
5691 according to pstate->length.
5693 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5695 * backtrace.c (scm_display_error_message): don't segv if message
5698 * error.h: prototype for scm_error_scm.
5700 * error.c (scm_error_scm): new procedure, reimplements scm-error
5701 in C and uses scm_error.
5703 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5705 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5706 pointer to the Scheme variable read-hash-procedures and intern it
5707 in scm_init_read. Modify scm_read_hash_extend and
5708 scm_get_hash_procedure to use the pointer.
5710 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5712 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5713 (SCM_KEYWORD_STYLE): defined.
5715 * read.c (scm_read_opts): add a keywords option. This isn't a
5716 boolean option, in case someone wants to add support for DSSSL
5718 Setup scm_keyword_prefix symbol.
5719 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5721 I've left keyword support disabled by default, since it doesn't
5722 seem to break the module system and it gives R4RS standard behaviour.
5723 It can be reactivated with (read-set! keywords 'prefix).
5725 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5727 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5728 before constructing arbiter.
5730 * eval.c (scm_m_define): Bugfix: Check that the object is a
5731 closure before setting the procedure property!
5733 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5735 * ports.c: Removed `ungetc-char-ready?'.
5737 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5739 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5740 (idea from Mikael: make it a pair so scm_permanent object only
5742 (scm_read_hash_extend): don't call scm_permanent_object.
5743 (ideas from Mikael): if chr is already in the list, replace its
5744 procedure instead of appending it again. If proc is #f, remove
5746 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5748 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5750 * gdbint.c (gdb_read): update scm_lreadr usage.
5752 * load.h: update prototypes.
5754 * load.c (scm_primitive_load, scm_read_and_eval_x,
5755 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
5757 * read.h: add prototype for scm_read_hash_extend. Change args for
5760 * read.c (scm_read_hash_procedures): new variable.
5761 (scm_read_hash_extend): new procedure.
5762 (scm_get_hash_procedure): new procedure.
5763 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5764 for extended # processing.
5765 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5766 scm_read_token): remove case_i, sharp arguments. Change callers.
5768 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5770 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5771 (SCM_CASE_INSENSITIVE_P): define.
5773 * read.c: add case-insensitive option to scm_read_opts.
5774 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5775 to determine whether to convert symbol case.
5776 (default_case_i): definition removed.
5777 * read.c (scm_read_token): if case_i, downcase ic before doing
5780 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5782 * configure.in: Added configuration option `guile-debug'.
5783 Configure with --enable-guile-debug if you want a bunch of extra
5784 functions used for debugging when developing Guile.
5786 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5788 * procs.c (make-cclo): New undocumented debugging procedure: Make
5789 compiled closure with internal procedure PROC and length LENGTH.
5790 Only compiled if GUILE_DEBUG is defined.
5792 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5794 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5796 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5798 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5799 with 3 or more args internally to the evaluator.
5801 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5803 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5804 with 3 or more args internally to the evaluator. This is mainly
5805 because we don't want to pass entry and exit points of the
5806 debug support twice, but it also seems to increase the speed of
5807 the evaluator for such calls (e. g. (+ 1 2 3)).
5809 * backtrace.c (scm_display_application): New procedure:
5810 display-application; Set fancy printing parameters individually
5811 for different types of display (backtrace, error, application).
5812 (These should of course be customizable!)
5814 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5815 clear the CHECK-flags.
5817 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5819 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5821 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5823 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5824 from pairs with a GLOC in the car.
5826 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5827 otherwise `symbol-hash' will behave badly.
5828 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5829 we get segmentation fault!
5831 * symbols.c: Added #include "weaks.h". New functions:
5832 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5833 moved to an extraneous library when we split libguile.)
5835 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5837 * filesys.c (scm_stat): stat now takes fport arguments too as
5838 documented in the manual.
5840 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5842 * debug.c (scm_single_step): Bugfix: Call continuation with
5843 scm_call_continuation instead of throwing to it.
5845 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5847 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5848 argument wasn't declared to be optional.
5850 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5852 * stime.c (scm_init_stime): Add feature "current-time".
5854 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5856 * throw.h: prototype for scm_exit_status.
5857 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5858 args to derive an exit status. Allows (quit) to work from a
5860 (scm_exit_status): new function.
5863 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5865 * eval.c (scm_deval): Removed some old code.
5866 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5868 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5871 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5874 * procs.c: Introduce the existent C function scm_thunk_p at the
5875 Scheme level as well.
5877 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5879 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5880 used from C to easily lookup the value of a symbol in the current
5883 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5885 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5886 scm_init_unif in this file. This will also fix a previous problem
5889 * configure.in: Added AM_MAINTAINER_MODE
5891 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5893 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5896 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5898 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5899 source files that are not always included in libguile but should
5900 have their dependencies calculated by automake. This variable is
5901 recognized by automake, no further magic is needed.
5902 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5903 to deal exclusively with *.lo files, as it seems. The *.o files
5904 are built automatically when the corresponding *.lo file gets
5907 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5909 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5912 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5914 * unif.c (scm_array_set_x): minor change to argument error checking.
5916 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5918 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5919 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5920 They should only be included in the library at configure.in's
5922 (libguile_la_LDADD): Include the appropriate .lo files here.
5923 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5924 so we know when to build them (and their .lo bretheren).
5925 * configure.in (LIBLOBJS): New substituted variable. We let
5926 configure decide which .o files to include in LIBOBJS, and then
5927 put the corresponding list of .lo files in LIBLOBJS. The latter
5928 is what we pass to libtool.
5929 * Makefile.in, configure: regenerated.
5931 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5933 * symbols.c (scm_sysintern0): New function. Contains the core of
5934 old scm_sysintern but doesn't take a second value argument.
5935 (scm_sysintern): Now uses scm_sysintern0.
5936 (scm_sysintern_no_module_lookup): Renamed to
5937 scm_sysintern0_no_module_lookup and doesn't take a second value
5938 argument any longer.
5940 * symbols.h (scm_sysintern0: Added declaration.
5942 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5943 scm_sysintern when interning option keys. Otherwise we risk
5944 destroying the values of already interned variables.
5946 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5947 scheme-level boolean (use SCM_NFALSEP).
5949 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5951 (scm_backtrace): New function. (C version of old function from
5952 boot-9.scm) Motivation: Make it possible to display backtraces
5953 without depending on boot-9.scm. (I'm uncertain if this
5954 motivation is good enough...)
5956 * root.h (scm_root_state): Add member the_last_stack_var.
5957 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5959 * root.c (mark_root): Mark scm_the_last_stack_var.
5961 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5964 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5966 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5967 1. mark_lazy_catch didn't mark the smob.
5968 2. Both functions above have standard variants:
5969 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5970 free_lazy_catch --> scm_free0.
5972 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5974 * throw.c (scm_internal_lazy_catch): New function.
5975 (scm_lazy_catch): Rewritten to use it.
5976 (scm_ithrow): Handle the new lazy catch representation.
5977 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
5978 that doesn't have a jmpbuf is a lazy catch clause.
5979 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
5980 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
5981 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
5983 (scm_init_throw): Register the new lazy-catch smob type.
5984 * throw.h (scm_internal_lazy_catch): decl for new function.
5986 * throw.c (scm_internal_catch): Doc fixes.
5988 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
5989 configure.in. Including this might cause problems if applications
5990 that link against libguile include their own copies of alloca, but
5991 if they're using autoconf, they should be adding libguile to LIBS
5992 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
5993 the copy in libguile, and things will be okay. (I think.)
5995 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5997 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
5999 strop.h: move prototypes too.
6001 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6003 * posix.c (scm_init_posix): don't intern EINTR since it's now done
6006 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
6007 etc. I deleted them from filesys.c long ago, but didn't
6008 notice they were here too (although ineffective since
6009 sys/stat.h wasn't included).
6011 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
6013 * eval.c: Don't define alloca in GCC case. gcc will automatically
6014 use __builtin_alloca if appropriate.
6016 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
6018 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
6019 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
6020 that values of automatic variables are preserved. See comments
6021 for safe_setjmp for details.
6023 Change from Thomas Morgan:
6024 * variable.c: Include eq.h.
6025 (var_equal): New function.
6026 (variable_smob): Use var_equal as the discriminator for variables.
6028 * throw.c (s_throw): Remove extraneous declaration.
6030 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
6031 * eval.c: Add necessary CPP cruft to support that.
6032 * configure, Makefile.in, scmconfig.h.in: regenerated.
6034 Change from Thomas Morgan:
6035 * procprop.c (scm_procedure_properties): Convert the Scheme
6036 boolean returned by scm_procedure_p into a C boolean before using
6037 it as a condition for SCM_ASSERT.
6038 (scm_procedure_property): Likewise.
6040 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
6041 indications of Unixness.
6044 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6046 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
6048 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6050 * read.c (scm_lreadr): use scm_misc_error to improve one of the
6051 "unknown # object" error messages.
6053 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
6054 (scm_i_index) and declare it static. Add a 'direction' argument
6055 to indicate what way the search should go.
6056 (scm_i_index): throw out-of-range error instead of wrong-type-arg
6058 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
6059 strop.h: remove scm_i_index, scm_i_rindex prototypes.
6061 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6063 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
6065 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
6066 to avoid clash with various scsh forks.
6068 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
6070 The following two changes (ramap.c, throw.c) are motivated by the
6071 apparent unportability of forward declarations of static arrays of
6072 the form `static foo bar[];'.
6074 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
6075 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
6077 * throw.c (scm_throw): Moved above scm_ithrow.
6079 * options.h: Removed the extern declarations of scm_yes_sym and
6080 scm_no_sym since these are static.
6082 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6084 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6086 * Makefile.am: remove AWK=@AWK@.
6087 Add a rule for generating errnos.list.
6088 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6090 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6091 don't extract errnos, just set a variable (avoids the
6092 need to recompile error.c just because configure is run.)
6094 * unif.h: update prototypes.
6095 * unif.c (scm_uniform_array_read,write): change the offset and
6096 length arguments to start and end, for consistency.
6098 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6100 * ioext.h: update prototypes.
6101 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6102 scm_read_line_x, it's a more general procedure using an
6103 interface from scsh. read-line and read-line! are now defined
6105 Note that the new read-line trims the terminator
6106 by default, previously it was appended to the returned string. An
6107 optional argument specifies how to process the terminator (scsh
6108 compatible). For the old behaviour: (read-line port 'concat).
6109 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6110 returns a pair, but is converted to multiple values if the scsh
6113 socket.h: update prototypes.
6114 * socket.c (scm_recvfrom): for consistency with other procedures,
6115 take start and end as separate optional arguments.
6116 (scm_recv, scm_recvfrom): don't allow the second argument
6117 to be a size, only a buffer. Change the scheme names to
6118 recv! and recvfrom!. Don't return the buffer.
6120 * ioext.h, posix.h: move prototypes too.
6121 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6122 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6123 "read.h" and "unif.h".
6124 * ioext.c: include "chars.h"
6126 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6128 * dynl.c: The dynamic linking and module registration functions
6129 are now defined even when dynamic linking is not available for the
6130 host system. Some of their functionality can be done without
6131 dynamic linking; when it's really needed, they throw errors.
6133 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6135 * configure.in: Only define DYNAMIC_LINKING when one of the system
6136 dependent functions is detected.
6137 * dynl.c (scm_dynamic_func): New function to get the address of a
6138 function in a dynamic object.
6139 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6140 produced by scm_dynamic_func as the thing to call.
6142 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6144 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6145 (scm_register_module_xxx, scm_registered_modules,
6146 scm_clear_registered_modules): New functions.
6148 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6150 * symbols.c (scm_sysintern): Renamed to
6151 scm_sysintern_no_module_lookup.
6152 (scm_sysintern): New function to take the place of the old
6153 scm_sysintern. It uses the current toplevel lookup closure to give
6154 the symbol its value. This is a temporary hack to put packages
6155 like gtcltk into their own module.
6156 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6157 us whether `scm_top_level_lookup_closure_var' has been initialized
6159 * eval.c (scm_init_eval): Set it.
6161 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6163 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6164 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6166 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6168 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6169 scm_sys_dup): deleted: FD capability will be added to other
6171 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6172 scm_fd_free, fd_smob, scm_intern_fd.
6173 (scm_open): renamed from scm_sys_open. Return a port instead of
6174 an FD object. Make the mode argument optional.
6175 (scm_sys_create): deleted, it's just a special case of open.
6176 (scm_init_filesys): move interning of constants O_CREAT etc.,
6177 here (were previously using SCM_CONST_LONG macro).
6178 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6180 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6181 include "fports.h" and <stdio.h>
6182 (scm_stat, scm_select): don't support FD objects.
6184 * error.h: adjust scm_syserror_msg prototype.
6185 * error.c (scm_syserror_msg): take an extra argument for errno.
6186 Using the global value didn't always work, since it could be
6187 reset by procedure calls in the message or args arguments.
6189 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6190 I don't understand why the check was there (and what about the
6193 * strop.c (scm_string_copy): allow shared substrings to be copied.
6195 * unif.h: corresponding change to prototypes.
6196 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6197 recognize two new optional arguments: offset and length. Allow
6198 the port argument to be an integer (file descriptor, for scsh).
6199 Include <unistd.h> for "read" prototype.
6201 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6203 * socket.c: don't include filesys.h.
6205 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6207 * Makefile.am: add AWK=@AWK@ (?)
6209 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6211 Add a rule to generate errnos.c from errnos.
6212 * error.c (scm_init_error): include errnos.c.
6213 * errnos_cnvt.awk: new file, converts the list of errno codes to
6215 * errnos_get.c: new file.
6216 * errnos.default: new file, contains errnos to try if they can't
6217 be extracted from errno.h.
6218 * configure.in: if using GCC, try and extract errno codes from
6222 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6224 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6225 * Makefile.am: Made libguile into a libtool library.
6226 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6227 Set libtool_libs to indicate that libguile is a libtool library.
6228 See guile/ChangeLog for details.
6229 * .cvsignore: ignore "*.lo", the libtool library objects.
6231 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6233 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6234 use htons in getservbyport argument.
6236 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6238 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6239 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6242 * objprop.c (scm_object_property): No need to take the CDR of the
6243 value returned by scm_object_properties, since Aug 20 change.
6245 * configure.in: When checking for struct linger, #include
6246 <sys/types.h> as well as <sys/socket.h>. I've never known
6247 <sys/types.h> to cause any portability problems, and Solaris's
6248 <sys/socket.h> needs it.
6249 * configure: Rebuilt.
6251 I think the Sun compiler has chosen a perverse way to interpret
6252 ANSI declarations combined with K&R definitions. We'll
6253 appease it a little bit. But when it invades France, we fight.
6254 * print.c (scm_iprlist): Change 'tlr' argument to an int.
6255 * print.h (scm_iprlist): Here too.
6256 * numbers.c (scm_divbigdig): Change definition to match
6257 declaration in numbers.h.
6258 * unif.c (scm_makflo): Change definition to match declaration in
6261 * init.c (scm_boot_guile): Don't return the value of
6262 scm_boot_guile_1. This function doesn't return a value;
6263 scm_boot_guile_1 doesn't return a value (or return at all).
6265 * eval.c (unmemocopy): Add a semicolon to appease the Sun
6268 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
6269 compile. I have a feeling this function is a bad idea anyway ---
6270 one should always test for features, not systems.
6272 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
6273 semicolons. Only pure luck kept this from being noticed earlier.
6275 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
6277 * socket.c (scm_recvfrom): Added missing semicolon.
6279 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6281 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
6282 the buffer and start and end positions for scsh networking
6285 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
6287 * configure.in: Revert previous change to this file; the problem
6288 is due to transient automake weirdness.
6289 * configure: Rebuilt.
6291 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
6292 PLUGIN/guile.libs. configure generates the latter from the former.
6293 * Makefile.in: Rebuilt.
6295 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
6296 need this if we install scripts, like guile-snarf.
6297 * configure: Rebuilt.
6299 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6301 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
6303 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
6305 * socket.c (scm_addr_vector): fix faulty scm_listify.
6307 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
6309 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
6310 style block comment is no longer considered an error.
6312 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
6314 * PLUGIN/guile.libs.in: New file.
6315 * PLUGIN/guile.libs: Removed from repository.
6316 * configure.in: Create PLUGIN/guile.libs from
6317 PLUGIN/guile.libs.in. This is for including additonal libraries
6318 needed for dynamic linking.
6319 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
6320 instead of PLUGIN/guile.libs.
6322 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
6324 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
6326 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
6327 occurrences of the given element from the list, not just the
6328 first. This is how the Emacs Lisp functions behave, how the
6329 analogous Common Lisp functions behave, and (I believe) how the
6330 older Maclisp functions worked. I realize that this change may
6331 break code, but it seemed better to break it before the Guile
6334 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
6335 Their prototypes were already present in gc.h, but they weren't
6337 (scm_init_storage): Initialize scm_protects.
6338 * root.c (scm_protects): New element of scm_sys_protects.
6340 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
6342 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6344 * libguile.h: Added #include "libguile/net_db.h".
6346 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
6347 30 change. That file is only meant for communication between the
6348 configuration process and load.c. If code linked against libguile
6349 wants to get at the paths mentioned in libpath.h, it can call
6350 functions declared in load.h.
6352 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6354 * libguile.h: Removed #include "libguile/fdsocket.h"
6356 * net_db.c: Added #include <sys/socket.h>.
6358 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
6360 * filesys.c (scm_input_waiting_p): use select in preference to
6361 FIONREAD, since the latter doesn't detect EOF.
6362 Throw error if neither select nor FIONREAD available.
6364 * socket.c (scm_connect): take a port, not a fd object.
6365 (scm_fill_sockaddr): throw an error if fam is not recognised.
6366 (scm_bind): use scm_fill_sockaddr.
6367 (scm_listen): take a port, not a fd object.
6368 (scm_accept): take and return a port. return #f in the car if
6369 address can't be got
6370 (scm_sock_fd_to_port): new procedure.
6371 (scm_socket): use scm_sock_fd_to_port.
6372 (scm_addr_vector): throw error if unrecognised address type.
6373 take an extra argument with the calling procedure name.
6374 (scm_getsockname): take a port. return #f if address can't be got.
6375 (scm_getpeername): take a port. return #f if address can't be got.
6376 (scm_recvfrom): take a port. return #f for address component if can't
6378 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6379 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6381 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6383 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6384 use separate data pointers, to allow them to be designed
6385 independently and reused.
6386 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6387 Renamed from catch_body, catch_handler, and uncaught_throw; made
6389 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6391 (scm_catch): Use the above.
6392 (scm_throw): Don't bother printing a message for an uncaught
6393 throw; we establish a default handler in init.
6394 * throw.h (scm_internal_catch): Prototype updated.
6395 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6397 (struct scm_body_thunk_data): New structure, used as data
6398 argument to scm_body_thunk.
6399 * init.c (struct main_func_closure): New structure, packaging up
6400 the data to pass to the user's main function.
6401 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6402 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6403 scm_internal_catch to establish a catch-all handler, using
6404 scm_handle_by_message. This replaces the special-case code in
6406 (invoke_main_func): Body function for scm_internal_catch; invoke
6407 the user's main function, using the main_func_closure pointer to
6408 decide what to pass it.
6409 * root.c (struct cwdr_body_data): Remove handler_proc member.
6410 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6411 (cwdr_handler): Removed.
6413 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6415 * socket.h (SCM_P): update bind prototype.
6416 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6417 include "feature.h".
6418 (scm_socket): return a port, not a file descriptor object.
6419 include "fports.h" and <unistd.h>
6420 (scm_bind): take a port, not a file descriptor object.
6421 take an extra argument for address args.
6423 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6424 INADDR_NONE, INADDR_LOOPBACK.
6426 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6428 * init.c: include net_db.h and not fdsocket.h.
6429 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6431 * Makefile.am: corresponding changes.
6432 * socket.h: renamed from fdsocket.h, fix names.
6433 * net_db.h: renamed from socket.h, fix names.
6434 * socket.c: renamed from fdsocket.c.
6435 remove _sys from procedure names.
6436 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6437 add "socket" to features list.
6438 * net_db.c: renamed from socket.c.
6439 remove _sys from procedure names.
6440 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6441 add "net-db" to features list.
6442 include "net_db.h". don't include <sys/socket.h> or
6445 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6447 * tags.h (scm_tags): Removed comma at end of last enumerator.
6449 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6451 Don't use GCC extensions to allocate space for debugging frames.
6452 (Here he goes again! Why do we put up with this?!)
6453 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6454 an scm_debug_info structure, not an in-line array of them. Add
6455 'info' member, to say how many vect elements we've used, for eval
6457 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6458 a new variable debug_info_end to mark the end of vect, instead of
6459 the address of the 'info' pointer itself.
6460 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6461 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6462 (SCM_APPLY): Explicitly allocate space for debug.vect.
6463 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6464 * stacks.c: Adjusted for new debug frame structure.
6465 (RELOC_INFO, RELOC_FRAME): New macros.
6466 (stack_depth, read_frames): Use them, and new scm_debug_frame
6467 element 'info', instead of magically knowing that eval frames have
6468 an info pointer sitting after vect.
6469 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6471 (scm_init_stacks): Formatting tweaks.
6473 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6475 Give GCC more control flow information, so it can be sure that
6476 variables aren't used uninitialized.
6477 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6478 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6479 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6480 scm_misc_error): Tell GCC that these functions never return.
6481 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6482 out the field type, call abort if SCM_ASSERT returns, to placate
6484 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6485 scm_wta ever returns. We can't handle this case anyway, and this
6486 gives the optimizer more information.
6487 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6488 scm_wta ever returns.
6490 In some cases, the code is fine, but GCC isn't smart enough to
6491 figure that out; this usually happens when one variable is only
6492 initialized and used when a particular condition holds true, and
6493 we know that condition will never change within a given invocation
6494 of the function. In this case, we simply initialize the variables
6495 to placate the compiler, hopefully to a value which will cause a
6496 crash if it is ever actually used.
6497 * print.c (scm_iprin1): Initialize mw_pos.
6498 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6499 * throw.c (scm_ithrow): Initialize dynpair.
6500 * unif.c (scm_uniform_vector_ref): Initialize cra.
6501 * struct.c (init_struct): Initialize prot.
6502 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6504 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6505 if EXPR contains no expressions.
6507 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6509 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6510 cause an infinite loop (???). So much for the algebraic
6511 equivalency of variable-sized arrays and alloca...
6513 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6515 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6516 a SCM boolean, not a C boolean.
6518 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6520 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6521 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6522 rules for raising scm_mtrigger. Previously, unfortunate but not
6523 unlikely circumstances could result in almost constant invokation
6524 of the gc. Now, this situations should be less likely, but they
6525 are not prevented completely.
6527 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6529 * numbers.c (scm_fuck): Procedure removed; looks like old test
6531 * numbers.h: Prototype removed.
6533 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6535 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6536 array to a pointer, to match my Nov 21 change in eval.c.
6538 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6540 * libguile.h: Added #include "libguile/backtrace.h", #include
6541 "libguile/stacks.h".
6543 * strings.c (scm_string scm_make_string scm_string_ref
6544 scm_string_set_x scm_string_equal_p scm_string_append):
6545 Bugfix according to scm patch from Aubrey Jaffer:
6546 Corrected long-standing
6547 (not (eqv? (integer->char 128)
6548 (string-ref (make-string 1 (integer->char 128)) 0)))
6549 bug found by John Kozak <jk@noontide.demon.co.uk>.
6551 * strports.c, strports.h: Make scm_eval_0str return the value of
6552 the last expression evaluated (previously, it returned void).
6554 * strports.c, strports.h: New function: scm_read_0str. Does what
6557 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6559 * simpos.c (scm_getenv): return #f if string can't be found in the
6560 environment instead of throwing an exception, for compatibility
6561 with numerous other systems.
6563 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6565 * Makefile.am (.c.x): Use guile-snarf.
6566 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6568 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6570 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6572 * backtrace.c (scm_display_error_message): Made non-static, and
6573 renamed from display_error_message.
6574 * backtrace.h (scm_display_error_message): Added extern decl.
6575 * throw.c (uncaught_throw): Use it to display the error message.
6577 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6579 * inet_aton.c: Use #if 0, not #ifdef 0.
6581 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6583 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6584 to convert the returned value.
6585 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6586 the offset argument.
6588 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6590 Add new interface to catch/throw, usable from C as well as
6592 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6593 (scm_internal_catch): New function, replaces...
6594 (scm_catch_apply): Deleted.
6595 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6596 mechanism which is a bit more code, but can be used nicely from C
6597 and implement the Scheme semantics as well.
6598 (scm_internal_catch): This is the replacement; it's named after
6599 the analogous function in Emacs.
6600 (scm_catch): Reimplemented in terms of the above.
6601 (struct catch_body_data, catch_body, catch_handler): New
6602 functions, used by scm_catch.
6603 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6604 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6605 support for new cwdr.
6607 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6610 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6612 * acconfig.h: Added DYNAMIC_LINKING symbol.
6613 * configure.in: Add option and checks for dynamic linking.
6614 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6615 dynl.h: New files for dynamic linking support.
6616 * Makefile.am (libguile_a_SOURCES):
6618 (modinclude_HEADERS): Added "dynl.h".
6619 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6621 * init.c (scm_boot_guile_1): Call
6622 scm_init_dynamic_linking to initialize dynamic linking support.
6624 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6626 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6627 (as we Schemers say). It needs to be global, so that I can tweak
6628 it for the proper operation of unexec.
6629 (scm_boot_guile_1_live): New variable, see above.
6631 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6633 * guile-snarf.sh: Removed.
6634 * PLUGIN/guile.libs: Added dependency for -lm.
6635 * acinclude.m4: Renamed from aclocal.m4.
6636 * PLUGIN/greet: Removed.
6637 * Makefile.am, aclocal.m4: New files.
6638 * configure.in: Updated for Automake.
6640 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6642 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6643 and not top_level_lookup_thunk_var.
6645 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6647 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6649 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6651 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6652 Scheme function, instead of syntax. Single argument is now a
6655 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6657 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6658 scm_ra_divide): Properly terminate statements passed as arguments
6659 to IVDEP macros. (Thanks to Bernard Urban.)
6661 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6662 with non-constant sizes. (Thanks to Bernard Urban.)
6664 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6666 It's an "eval closure", not an "eval thunk." A thunk is a
6667 function of no arguments.
6668 * root.h (struct scm_root_state): Renamed
6669 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6670 (scm_top_level_lookup_closure_var): Renamed from
6671 scm_top_level_lookup_thunk_var.
6672 * root.c (mark_root): Uses changed.
6673 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6674 * init.c (scm_start_stack): Uses changed.
6675 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6676 Change scheme-visible name to *top-level-lookup-closure* from
6677 *top-level-lookup-thunk*.
6679 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6681 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6682 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6684 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6686 * gc.c (struct scm_heap_seg_data): Doc fixes.
6688 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6689 sweeping. Then, prepend each segment's free cells to its
6690 freelist, rather than wiping out the old value. (Thanks to Marius
6693 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6694 scm_check_freelist, scm_debug_newcell): New functions and
6695 variables, for debugging freelist problems.
6696 * pairs.h (SCM_NEWCELL): New debugging version added.
6697 * gc.h (scm_debug_newcell): Added extern declaration, used by
6698 debugging version of SCM_NEWCELL.
6700 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6702 On some systems <libc.h> conflicts with <unistd.h>, and should not
6703 be #included at all.
6704 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6705 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6706 * configure.in: Call it.
6707 * posix.c, filesys.c: Use its results to decide whether or not to
6709 * configure, scmconfig.h.in: Rebuilt with autoconf and
6712 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6714 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6715 pointer to the stdio stream before calling scm_setbuf0, so the
6716 latter will be able to retrieve it. I'm surprised this didn't
6717 segfault earlier. (Thanks to Christopher Lee.)
6719 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6721 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6724 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6726 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6727 number of stack narrowing specifier pairs. The first specifier in
6728 a pair controls inner border, the second the outer border. A
6729 number means cut that number of frames, a procedure object means
6730 cut until that object is found in operator position in a frame.
6732 * root.c (cwdr): Bugfix.
6734 * read.c: Recording of positions disabled by default.
6736 * procs.c (scm_closure_p): New function.
6738 * posix.c (scm_tmpnam): New function.
6740 * load.c: Added #include "throw.h".
6741 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6744 * load.c, load.h (scm_read_and_eval_x): New function.
6746 * eval.c: Renamed debug option "deval" to "debug".
6748 (scm_eval_x): `eval!' is no longer accessible from the scheme
6749 level. Motivation: We can't allow operations which introduce
6750 glocs into the scheme level. Guile's type system can't handle
6751 these as data. Use `eval' or `read-and-eval!' as replacement.
6753 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6754 SCM_CONSP since this is a macro!; Set vframe.prev to
6755 scm_last_debug_frame instead of 0. In this way we can look
6756 "above" the virtual start stack frame if we wish.
6757 (scm_debug_hang): New function: Useful for debugging Guile in
6758 certain tricky situations. Will probably be removed later...
6760 * debug.h: Changed semantics of debug option "backtrace". This
6761 option now only indicates whether we want automatic backtrace at
6764 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6766 * ports.c: #include "filesys.h"
6767 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6769 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6770 Motivation: This is system specific code which is related to file
6771 I/O. It also may use select. Added code by Gary Houston to
6772 detect presence of character in stdio buffers.
6774 * libguile.h: #include "libguile/libpath.h"
6776 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6777 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6778 SCM_SITE_DIR; Install libpath.h among the other include files.
6780 * load.c, load.h (scm_sys_package_data_dir): New function.
6782 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6784 * stacks.h: Bugfix: Don't use tail-array length field as stack
6785 length field! This screwed GC.
6787 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6789 * _scm.h: Added #ifndef around definition of macros min and max.
6791 * __scm.h: Added hooks for threads to plugin to in ints protection
6792 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6793 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6794 the main code in these macros duplicated and spread over multiple
6795 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6796 SCM_THREAD_SWITCHING_CODE.
6798 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6800 * snarf.h: New file.
6801 * guile-snarf.sh: New file.
6802 * Makefile.in (inner_h_files): Added snarf.h
6803 (ancillary, install, uninstall, distclean): Added actions for
6805 (.c.x): Use guile-snarf.
6806 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6807 (gen_c_files): Note that these depend on guile-snarf.
6808 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6809 now in "snarf.h". Added #include "snarf.h" to get them.
6810 * libguile.h: Added #include "snarf.h".
6811 (Patches applied and tweaked by Jim Blandy.)
6813 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6815 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6816 standards suggest against providing prototypes for system
6817 functions. Thanks to Greg Troxel.
6819 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6821 * strports.c (scm_eval_0str): New function.
6822 #include "read.h", to get prototype for scm_read.
6823 * Makefile.in (strports.o): Update dependencies.
6824 * strports.h: New prototype.
6826 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6827 scheme name from "int?" to "integer?". It seems to do the job.
6828 * numbers.h: Rename prototype too.
6829 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6832 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6833 scm_num_eq_p): Rename these according to R4RS conventions: call
6834 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6835 to making libguile R4RS compliant without ice-9...
6837 * load.c (scm_sys_search_load_path): Search for files under all
6838 extensions listed in the %load-extensions variable. If FILENAME
6839 is absolute, return it unchanged, without searching the load path.
6840 (scm_loc_load_extensions): New variable, pointing to
6841 %load-extensions' value cell.
6842 (scm_init_load): Initialize it, and the value it points to.
6843 (scm_primitive_load_path): Improve error reporting.
6845 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6846 of new Scheme variable %load-hook.
6847 (scm_primitive_load): Apply %load-hook to filename.
6849 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6851 * configure.in: add tests for figuring out whether buffered data
6852 is available in a FILE structure, which is needed by char-ready.
6854 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6857 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6858 exceptions using misc_error instead of syserror. It seems a bit
6859 odd to throw an exception if a string can't be found in the
6860 environment, but it's consistent with open-file, stat etc.
6861 (simpos.h): remove sys_ from getenv.
6863 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6864 occurs, throw an error instead of returning errno. Return value
6866 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6868 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6870 * filesys.c (scm_stat2scm): derive file type and permissions from
6871 the stat mode and append them to the returned vector.
6872 There isn't much overhead in doing this and it avoids the need to
6873 work with S_IRUSR et al. in Scheme.
6874 Define symbols scm_sym_regular etc.
6875 (scm_init_filesys): don't intern S_IRUSR etc.
6877 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6878 and s_primitive_load_path.
6880 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6882 * error.h: don't declare error symbols. prototype for scm_misc_error.
6884 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6887 * error.c: use SCM_SYMBOL to set up error keys.
6888 scm_misc_error: new procedure.
6890 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6892 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6893 between `#!' and `!#' is ignored.
6894 (skip_scsh_block_comment): New function.
6896 * feature.c (scm_set_program_arguments): New argument, FIRST.
6897 * feature.h: Update prototype.
6898 * init.c (scm_boot_guile_1): Pass new argument to
6899 scm_set_program_arguments.
6901 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6903 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6904 (scm_boot_guile): Call scm_set_program_arguments here, later than
6905 the old initialization.
6907 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6908 initialization procedure.
6909 - Delete in, out, err arguments; there are other perfectly good
6910 ways to override these when desired.
6911 - Delete result argument; this function shouldn't ever return.
6912 - Rename init_func argument to main_func, for less confusion.
6913 - Delete boot_cmd argument; main_func is more general.
6914 -Add 'closure' argument, to help people pass data to main_func
6915 without resorting to global variables.
6916 - Abort if reentered; don't bother returning an error code.
6917 - Call scm_init_standard_ports to set up the default/current
6918 standard ports; no need to pass them to scm_start_stack.
6919 - Remove code to evaluate the boot_cmd, and start the repl; let
6920 the user do something like that in main_func if they want.
6921 - Remove code to package up a return value; main_func can do any
6923 - Call exit (0), instead of returning.
6924 (scm_start_stack): Don't initialize the I/O ports here; that's
6925 weird. Delete in, out, err arguments. Move guts to
6926 scm_init_standard_ports, scm_stdio_to_port.
6927 (scm_init_standard_ports): New function, to set up current and
6928 default standard ports.
6929 (scm_start_stack, scm_restart_stack): Make these static.
6930 * init.h (scm_boot_guile): Adjust declaration.
6931 (scm_start_stack, scm_restart_stack): Remove externally
6932 visible declarations for these.
6933 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6935 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6936 written out several times in scm_start_stack.
6937 * fports.h: New declaration for the above.
6939 * feature.c (scm_set_program_arguments): New function.
6940 * feature.h: New declaration for the above.
6942 * ports.c: Formatting tweak.
6944 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6946 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6947 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6948 for obtaining the address of a car or cdr field. Motivation:
6949 &SCM_CXR make assumptions about the internal structure of the
6952 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6953 Motivation: see SCM_CXRLOC.
6955 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6956 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6957 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6958 Motivation: Safer use. Some other macros are defined in terms of
6959 these operations. If these are defined using the SCM_SETCXR
6960 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6961 to inefficiency and an <e1> with side-effects could potentially
6962 break. Also, these particular operations are heavily utilized in
6963 the garbage collector. In unoptimized code there will be a
6966 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6967 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6968 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
6969 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
6970 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
6971 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6972 vports.c: Cleaned up use of pairs: Don't make any special
6973 assumptions about the internal structure of selectors and
6974 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6975 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
6976 (Among other things, this change makes it easier to build Guile
6977 with certain compilers which have problems with casted lvalues.)
6979 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6981 * stacks.c: Improve selection of relevant stack frames when making
6982 a stack object. Introduce one level of indirection in the stack
6983 object to make it possible to "narrow" to a certain region of the
6984 stack. This facilitates making use of more clever algorithms (not
6985 implemented) for selecting relevant frames and gives a cleaner
6986 design since selection of frames can be done independently of
6987 extraction of frames from the real stack.
6988 (scm_stack_id): Also take #t as argument which means look at
6991 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
6992 Turn n_tail into an integer directly representing current number
6993 of frames in stack. Add field tail.
6995 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
6997 * debug.c (scm_make_memoized): Made it available at scheme level.
6998 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
6999 SCM_NIMP before applying heavier predicates in argument checking.
7000 (scm_local_eval): Also take memoized object as argument.
7002 * backtrace.c (scm_display_error): Just a safety measure: Stacks
7003 aren't created with zero length, but should such a strange
7004 creature suddenly turn up...
7006 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
7008 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
7009 `del', for the sake of C++ compilers. (Patch applied by JimB.)
7011 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
7013 * variable.c (scm_make_variable): Make the name hint optional, as
7015 (anonymous_variable_sym): Renamed from variable_sym. All uses
7018 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
7019 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
7020 of scm_primitive_load_path was also changed to
7021 "primitive-load-path", from "%try-load-path". Callers changed.
7022 We'd like to respect the convention that a function named
7023 "try-mumble" should behave just like the function called "mumble",
7024 but return #f instead of signalling some error.
7025 * load.h: Rename prototypes.
7027 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7029 * print.c (make_print_state, grow_print_state), print.h: Modified
7030 the print state representation: Don't use a tail array for
7031 recording of circular references. Resizing of the print state
7032 structure invalidates the print state pointer. To avoid passing
7033 around an indirect print state reference to all printing
7034 functions, we instead let the print state reference a resizable
7037 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7039 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
7040 Don't crash when passed an improper list terminated by a
7041 non-immediate value.
7043 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
7045 Allocate data for structures on an eight-byte boundary, as
7046 required by the tagging system.
7047 * struct.c (alloc_struct): New function.
7048 (scm_make_struct, scm_make_vtable_vtable): Call it.
7049 * struct.h (scm_struct_n_extra_words): Bump to 3.
7050 (scm_struct_i_ptr): New "field".
7051 * gc.c (scm_gc_sweep): When we need to free the data, use the
7052 information stored by alloc_struct to find the beginning of the
7053 block allocated to the structure, so we can free it.
7055 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7057 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
7060 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
7061 (scm_debug_info): New member: id.
7063 * stacks.c: Stacks are now represented as structs; Stacks have an
7064 id given to them by `start-stack'.
7065 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
7067 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
7068 Changed stack representation.
7070 * debug.c (scm_procedure_name): Try procedure property `name' for
7071 compiled closures aswell.
7073 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
7075 * eval.c: scm_i_name moved to gsubr.c
7076 (scm_m_define): Record names of all kinds of procedure
7077 objects. (Earlier, only closures were recorded.)
7079 * procprop.h: Added declaration of scm_i_name.
7081 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7082 (scm_make_gsubr): Record names of compiled closures.
7084 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7086 * debug.c, debug.h: Removed obsolete code.
7088 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7089 stacks.c: Renamed regs --> scm_contregs.
7091 * print.c (scm_free_print_state): Cleanup print state before
7092 returning it to pool. It is better to do it here than in
7093 scm_prin1 since scm_prin1 is called often.
7095 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7096 s_set_source_property_x): Check that first argument is a pair or a
7099 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7100 scm_i_line, scm_i_column and scm_i_breakpoint global.
7102 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7103 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7106 * debug.h: Added debug object smob declaration and macro
7109 * configure.in: Build with backtrace.o and stacks.o if debug
7112 * Makefile.in: Added entries for new files: backtrace.c,
7113 backtrace.h, stacks.c and stacks.h.
7115 * symbols.c (scm_sym2ovcell): Fixed documentation.
7117 * _scm.h (min, max): Added.
7119 * async.c: Moved `min' macro to _scm.h.
7121 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7122 SCM_BACKTRACE_INDENT.
7124 * eval.c: Added new debug options `maxdepth' and `indent'.
7126 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
7128 * print.h: Added selector SCM_PRINT_STATE.
7130 * print.c: New functions: scm_make_print_state,
7131 scm_free_print_state.
7133 * print.h: Added declarations for scm_make_print_state,
7134 scm_free_print_state.
7136 * debug.c (scm_m_start_stack): New acro.
7138 * debug.h: Small cleanup.
7140 * init.c (scm_boot_guile_1): Moved scm_init_debug below
7143 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

7163 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,

7165 declare functions with prototypes. (Patch thanks to Marius
7168 More prototype-related changes from Marius Vollmer:
7169 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7170 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7171 * ports.h (ptobfuns): Added prototypes. This means some casting in
7173 * fports.c: Added casts for initializations, since the functions
7174 are defined to take FILE * as their stream argument, not SCM.
7175 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7176 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7177 to `char *str_data' to conform to prototype.
7179 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7181 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7183 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7185 * stime.c, stime.h: use SCM_P method.
7187 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7189 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7190 be given at least two arguments. Insist that lst's last element
7191 be a list, but don't make any requirements of its predecessors.
7193 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7195 * eval.c (scm_nconc2last): Revert last change; there seems to be
7196 other stuff going on here.
7198 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7200 * eval.c (scm_nconc2last): Make sure that each element of lst
7201 (which is a list of argument lists, except for the tail) is a
7202 proper list, i.e., finite and terminated by '().
7204 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7206 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7209 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7210 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7213 * vectors.c (scm_make_vector): Fill vectors with the undefined
7214 value, to help make Guile Scheme code more portable to other
7217 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7218 * symbols.h, tags.h: Doc fixes.
7220 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7222 * async.c (scm_take_signal): Doc fixes.
7224 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7226 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7227 want to subtract it from the modulus; we just want to leave it
7230 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7232 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7235 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7237 * throw.c (scm_catch_apply): Finished implementation of
7240 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7242 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7244 (scm_init_filesys): set "i/o-extensions" feature.
7247 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7249 * Makefile.in (root.o): Correct dependencies.
7251 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7253 * Makefile.in: Added dependency entry for root.o.
7255 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
7256 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
7258 * init.c (scm_start_stack): Set initial root continuation number
7261 * procs.c: New function: scm_thunk_p.
7263 * procs.h: Added declarations of scm_thunk_p.
7265 * root.c: Renamed `call-with-new-root' -->
7266 `call-with-dynamic-root'.
7267 (cwdr): Removed allocation of new root state. This should be done
7268 separately by use of scm_make_root.
7269 (scm_apply_with_dynamic_root): New function: Does what it
7270 sounds like. Needed when spawning threads.
7272 * root.h: Added member last_debug_frame to root state.
7273 Added #include "libguile/debug.h"
7275 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
7276 arguments. The motivation is that code in root.c needs catch
7277 functionality, and we want to avoid code duplication.
7278 New functions: scm_catch, scm_lazy_catch. These are wrappers for
7279 scm_catch_apply. scm_lazy_catch is intended to introduce catch
7280 handlers that run without popping the stack into the dynwind
7283 * throw.h: Added prototypes for scm_catch_apply and
7286 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7288 * root.h (scm_root, scm_set_root): Decouple thread support details
7289 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
7290 SCM_SET_THREAD_LOCAL_DATA.
7292 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
7293 and tortoise scanning loop.
7295 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
7297 * Makefile.in: Rebuild dependencies.
7299 * libguile.h: #include "libguile/print.h" before "smob.h", since
7300 the latter uses the print_state structure.
7302 * throw.c (scm_ithrow): Use the correct variable when checking to
7303 see if a given element of scm_dynwinds is a valid catch.
7305 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
7306 structure, abort; don't just silently ignore the garbage.
7308 * _scm.h: #include "print.h" here, since it seems to be used just
7310 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
7311 strports.c, unif.h: Don't #include "print.h".
7313 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7315 * feature.h (scm_loc_features): Removed external declaration.
7316 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
7318 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7320 * feature.c (scm_init_feature): Added threads feature (needs to be
7321 initialized here, since features doesn't exist when
7322 scm_init_threads is called).
7324 * libguile.h: Added #include "libguile/../threads/threads.h".
7325 (This is a kludge to get thread support working. This should be
7328 * configure.in, acconfig.h: Added flags for thread support.
7330 * scmsigs.c: Define `signal' to be `pthread_signal' if using
7333 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
7334 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
7337 * _scm.h: Added conditional #include "threads.h"
7339 * __scm.h (SCM_ASYNC_TICK): Added call to macro
7340 SCM_THREADS_SWITCHING_CODE.
7342 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
7343 allocate the basic dynamic root object.
7344 (scm_boot_guile): Added call to scm_init_root.
7346 * root.c, root.h: Added root smob.
7347 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
7348 functions: Implements dynamic roots mostly according to spec in
7349 SCM manual. Main difference is that the second argument is a
7350 throw handler rather than an error "thunk".
7352 * root.h: Added declaration of scm_init_root.
7354 * root.c: Added #include "genio.h", #include "smob.h", #include
7355 "pairs.h", #include "throw.h", #include "dynwind.h", #include
7357 (scm_init_root): Added #include "root.x".
7359 * throw.c: Added #include "stackchk.h"
7360 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
7361 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
7362 can be used in scm_call_with_new_root; Added reenabling of stack
7363 checking when catching a throw.
7365 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
7367 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
7369 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
7370 element is not found, as per R4RS.
7372 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7374 * list.c: Doc fixes throughout.
7376 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7378 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7379 declare the char * to be const. Avoids a warning in rgx.c.
7381 * ports.h: spelling fix.
7383 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7386 * load.c (scm_sys_try_load_path): throw an error if file not found
7387 (like it says it in NEWS).
7389 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7391 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7392 PROPS slot to '(), not #f; it's an empty alist.
7394 * throw.h, throw.c: Use SCM_P instead of #if hair.
7396 Remove special support for uncaught throws; see throw.c for
7398 * throw.c (uncaught_throw): New function.
7399 (scm_ithrow): Call uncaught_throw if we don't find a throw
7400 target; don't mess with scm_bad_throw_vcell.
7401 (scm_bad_throw_vcell): Variable deleted.
7402 (scm_init_throw): Don't initialize it.
7404 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7407 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7409 * numbers.c (scm_istr2int): If the number is short (as most
7410 numbers are), just call scm_small_istr2int to deal with it.
7411 (scm_small_istr2int): New function, created by un-#ifdefing the
7412 non-bignum version of scm_istr2int and renaming it.
7414 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7416 * load.c (scm_sys_try_load): don't check whether value returned
7417 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7418 Change the Scheme name from %try-load to primitive-load.
7420 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7421 Can avoid passing a message, allowing it to be derived in the
7422 error handler (e.g., if we want to throw to the key both from
7425 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7427 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7428 references now have a new appearance which is more compact and
7429 also gives a clue about what the target of the reference is.
7430 By setting parameters in the print state, more fancy printing can
7431 be achieved. This is used by the (not yet commited) backtrace
7434 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7436 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7439 * print.c: Added #include "struct.h". Removed function
7442 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7443 scm_iprin1. Removed prototype for scm_prlist.
7445 * arbiters.c (prinarb),
7446 async.c (print_async),
7447 debug.c (prindebugobj, prinmemoized),
7448 eval.c (prinprom, prinmacro),
7449 filesys.c (scm_fd_print, scm_dir_print),
7451 mallocs.c (prinmalloc),
7452 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7453 smob.h (scm_smobfuns),
7454 srcprop.c (prinsrcprops),
7456 unif.c, unif.h (scm_raprin1, rapr1),
7457 variable.c (prin_var): Changed argument `int writing' to
7458 `scm_print_state *pstate'.
7460 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7461 that it will be called before scm_init_print.
7463 * print.c (scm_prin1): Print states are now allocated when calling
7464 scm_prin1 and then passed around to all printing functions as an
7465 argument. A cache `print_state_pool' enables reuse of print
7467 (scm_make_print_state): New function.
7468 (scm_iprin1): Adaption to print states.
7469 (scm_iprlist): An initial "hare and tortoise" scan brings down
7470 time complexity to O (depth * N). (Better time complexity will be
7471 achieved when the printing code is completely rewritten.)
7473 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7475 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7476 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7477 it gets done whether or not the cache variable has a value.
7479 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7481 Distinguish #f and ().
7482 * __scm.h: #undef SICP.
7483 * pairs.h (SCM_EOL): Delete this definition, equating it with
7485 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7486 the value it used to have. Doc fixes, too.
7488 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7490 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7491 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7492 Lord's implementation of structs, allowing for tail arrays as
7493 described in the manual. Also fixed some bugs. (Both the interface
7494 and the implementation should be improved.)
7496 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7498 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7499 People who whish to see the source can do `(print-enable 'source)'.
7500 Removed #ifdef DEBUG_EXTENSIONS.
7502 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7504 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7505 integer (assuming for now accepting an integer is a good thing).
7507 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7508 %S will be used instead for write'ing arguments.
7510 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7511 asserts. fix a few other asserts.
7512 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7513 scm_uniform_vector_ref, scm_array_set_x,
7514 scm_dimensions_to_unform_array): change args in
7515 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7516 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7517 scm_substring_fill_x): likewise.
7518 gsubr.c (scm_gsubr_apply): likewise.
7519 eval.c (SCM_APPLY): likewise.
7521 * eval.c (4 places): replace scm_everr with lgh_error or
7524 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7525 scm_memory_error): new procedures.
7526 scm_everr: deleted. can use scm_wta, dropping first two args.
7527 scm_error: convert NULL subr to SCM_BOOL_F.
7529 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7532 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7535 * error.c, error.h: new error keys: scm_arg_type_key,
7536 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7538 scm_wta: reimplement using lgh_error instead of scm_everr.
7540 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7542 * gdbint.c: scm_lread now has one more argument.
7544 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7545 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7546 loading source from non-file ports, which, e. g., happens when
7547 using the Emacs interface).
7549 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7552 * read.c: Added code for recording of positions of source code
7553 expressions; New functions: recsexpr, scm_lreadrecparen;
7554 _scm_make_srcprops --> scm_make_srcprops
7555 (scm_flush_ws): Removed updating of positions counters. This work
7556 is already done by scm_gen_getc
7558 * read.h: Added prototype for scm_lreadrecparen
7560 * print.c: Added #include "alist.h"
7562 * eval.c: Added #include "hash.h"
7564 * eq.c: Added #include "ramap.h"
7566 * options.c: Documentation fixes.
7568 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7569 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7570 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7571 --> scm_make_srcprops
7573 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7574 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7575 function calls in the definition of the whash access macros.
7577 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7579 * init.c (scm_boot_guile): Add level of indirection to
7580 scm_boot_guile_1() to ensure that stack base pointer is properly
7581 initialized. There was no guarantee that variable i was the
7582 highest/lowest variable on stack (i.e. the call frame of
7583 scm_boot_guile was not completely protected from gc).
7585 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7587 * ports.h (scm_port_table): put back file_name, it will be used to
7588 support debugging. Undo related changes in fports.c, ioext.c,
7591 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7593 * ports.h (scm_port_table): remove file_name member for now, it seems
7595 * fports.c (scm_open_file): don't set file_name in PTAB.
7596 (prinfport): don't use file_name in PTAB.
7597 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7598 * ports.c (scm_add_to_port_table): don't intialize file_name.
7599 (scm_port_file_name): remove for now.
7600 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7602 * fports.h (scm_mkfile): prototype deleted.
7603 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7605 * debug.c, unif.c: use scm_out_of_range instead of
7606 wta for range errors (ASSERT still needs work).
7608 * error.c, error.h (scm_out_of_range): new procedure.
7610 * error.c, error.h (scm_out_of_range_key): new key.
7612 * posix.c (scm_sync): #else was missing.
7614 * error.c, error.h: append _key to names scm_num_overflow and
7617 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7618 of consing an empty list.
7619 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7620 of macros, saves code and string space.
7621 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7622 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7623 lower case. Rename scm_syserror_m to scm_syserror_msg.
7624 error.h: prototypes for new procedures.
7626 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7628 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7630 * error.c, error.h: setup scm_num_overflow key.
7632 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7633 Remove definition of SCM_OVSCM_FLOW.
7635 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7637 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7638 explicit message and args.
7640 * error.c, error.h, __scm.h: change system_error_sym to
7643 * error.c (system_error_sym): remove leading %% from the Scheme name
7646 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7648 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7650 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7651 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7652 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7653 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7654 renamed. (These were introduced by unsupervised name
7657 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7659 * print.c: Added code for detection of circular references during
7660 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7661 a hook for printing of closures (accessible via print options).
7662 This leads to a split of calls to scm_iprin1 into two classes:
7663 elementary print operations (e. g. the code which prints a smob)
7664 still use scm_iprin1 while top level calls (like scm_display) use
7665 scm_prin1. scm_prin1 begins by clearing the data structure used
7666 to record reference information.
7668 * print.h: Added declarations of scm_prin1 and scm_prlist.
7670 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7672 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7674 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7676 * error.c (err_head): scm_iprin1 --> scm_prin1
7678 * debug.c: Adjusted header comment.
7682 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7684 * strerror.c: Doc fix.
7686 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7688 * gdbint.c (gdb_read): Now possible to run during GC.
7689 (unmark_port, remark_port): New functions.
7691 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7693 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7694 of allocating a new string object. Also, increase size by
7695 the factor 2 instead of 1.5.
7697 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7699 * __scm.h (SCM_P): Corrected to run under traditional C.
7701 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7704 * async.c: Calls to scm_sysintern corrected.
7706 * async.h (scm_async_clock): Redundant declaration removed.
7708 * continuations.c (scm_dynthrow): Redundant declaration removed.
7710 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7711 Definition typos corrected.
7713 * debug.h: Missing declarations of functions in debug.c added
7716 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7717 Missing declarations to functions in eval.c added.
7719 * filesys.c: Possibly uninitialized variable rv.
7721 * gc.h (scm_object_addr, scm_unhash_name): Missing
7722 declarations of functions defined in gc.c added.
7724 * genio.c: Possible typos str_data -> wstr_data. ???
7726 * genio.c: Possibly unintended shadowing of local variable
7727 `int c' (gotos out of scope of inner `c'). ???
7729 * init.c: Uninitialized `SCM last' may be used.
7731 * ioext.h: (scm_sys_isatty_p): Typo.
7733 * list.h (scm_list_head): Missing prototype for function in
7736 * numbers.c (scm_two_doubles): Changed from extern to static
7737 (is used only within numbers.c).
7739 * numbers.h: Repeated declarations removed.
7741 * ports.h (scm_close_all_ports_except): Declaration for the
7742 function defined in ports.c added.
7744 * posix.h: Missing declarations added.
7746 * procs.h (scm_make_subr_opt): Missing declaration added.
7748 * socket.h (scm_sys_gethost): Missing declaration added.
7750 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7752 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7753 Missing declarations added.
7755 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7757 * struct.c: Uninitialized variable `SCM answer' may be used.
7759 * unif.c (l2ra): Declaration prototype.
7761 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7762 defined in ramap.c).
7764 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7765 Redundant declarations removed (they are in ramap.h).
7767 * variable.h (scm_make_udvariable,
7768 scm_make_undefined_variable): Declaration corrected to
7769 correspond variable.c.
7771 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7772 Missing declarations added.
7774 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7776 * Makefile.in (distclean): Don't forget to delete fd.h.
7778 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7780 * fd.h.in, tags.h: Trivial cleanups.
7782 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7783 marksweep.h just declared functions from gc.c.
7784 * gc.h, libguile.h: Don't #include "marksweep.h".
7785 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7786 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7787 dependencies updated.
7789 * libguile.h: Don't #include "files.h"; it's been deleted.
7791 * files.c (scm_sys_delete_file): Moved to filesys.c.
7792 File is now empty; deleted.
7794 * filesys.c: scm_sys_delete_file is now here. Remove
7795 #if's; they seem to rely on remnants of an old portability
7796 regimen. If the problems come up again, solve them properly,
7797 using autoconf. Specifically: Don't test M_SYSV, and #define
7798 remove to be unlink if it's #defined; don't use remove just
7799 because HAVE_STDC_HEADERS is #defined.
7800 * filesys.h: Add declarations for scm_sys_delete_file.
7801 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7802 files.o, files.h, files.c, and files.x.
7803 * init.c: Don't #include "files.h", and don't call scm_init_files.
7805 Use SCM_P instead of PROTO; the latter intrudes on the user's
7807 * params.h: Deleted; definition of SCM_P moved to...
7808 * __scm.h: ... here, where it replaces PROTO macro.
7809 * libguile.h, smob.h: Don't #include "params.h".
7810 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7811 smob.h: Fix prototypes accordingly.
7812 * Makefile.in: Update dependencies.
7813 (inner_h_files): Remove params.h.
7815 * gc.c: #include "gc.h"; every module should include its header,
7816 to let the compiler cross-check the declarations against the
7819 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7820 simpos.h: #include "libguile/__scm.h".
7822 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7824 * init.c: Don't forget to #include smob.h and init.h.
7825 * Makefile.in: Dependencies updated.
7827 * smob.h: Use PROTO instead of #if __STDC__.
7829 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7831 * __scm.h: Doc fixes.
7833 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7834 <angles>; this allows `make depends' to work properly.
7836 * libguile.h: #include smob.h and pairs.h before the others; they
7837 define typedefs used by other headers.
7839 C files should #include only the header files they need, not
7840 libguile.h (which #includes all the header files); the pointless
7841 recompilation was wasting my time.
7842 * Makefile.in (all .o dependency lists): Regenerated.
7843 * libguile.h: Don't try to get a definition for size_t here...
7844 * __scm.h: Do it here.
7845 * _scm.h: Since this is the internal libguile header, put things
7846 here that all (or a majority) of the libguile files will want.

7949 * stackchk.h: #include "libguile/debug.h",
7951 * print.h, read.h: #include "options.h", since everyone who uses
7952 either of these files will need that.
7954 * smob.h: #include "ports.h", "genio.h", and "print.h", since
7955 anyone who uses this file will need them to define the smob
7956 printing functions. Also, get markers.h, since people will need
7957 to #define the mark functions.
7959 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
7960 * ports.h: ... to here.
7962 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7963 don't rely on archaic C default type rules.
7965 * fports.h: #include "libguile/ports.h", since you need that in
7966 order to parse this.
7968 * genio.h: #include "libguile/print.h", because you need that to
7969 parse this; don't bother #including "ports.h", since print.h gets
7972 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7974 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7975 this; it's now a reference to an element of *scm_root.
7977 * debug.h: Don't #include "options.h"; the compiler won't be able
7978 to find that once the headers are installed; instead, #include
7979 "libguile/options.h".
7980 * gc.h: Same, with marksweep.h.
7981 * mbstrings.h: Same, with symbols.h.
7982 * scmhob.h: Same, with _scm.h.
7983 * smob.h: Same, with params.h.
7985 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
7986 C files; there's no need for this, and it forces recompilations
7989 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
7991 * error.c (scm_error): declare scm_error_callback.
7993 * error.h: prototype for scm_error_callback.
7995 * __scm.h: define lgh_error.
7996 (SCM_SYSERROR): redefine using lgh_error.
7998 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
8000 * error.c (scm_error): new procedure.
8002 * error.h: prototype for scm_error.
8004 * Makefile.in (install): install scmconfig.h from the current
8005 directory, not $(srcdir).
8007 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8009 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8010 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8011 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

8017 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8018 vports.h, weaks.h: #include "libguile/__scm.h", not
8019 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
8020 dependencies are within libguile properly.
8022 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8024 * Makefile.in (.c.x): Simplify; there's no need to run this rule
8025 when scmconfig.h doesn't exist.
8027 * load.c (scm_sys_try_load): Correct spelling.
8029 * feature.c (scm_loc_features): Make this static.
8031 * Makefile.in (libpath.h): Omit trailing slash from path. We
8032 shouldn't require it of users, so why put it here?
8034 Move code to initialize and search %load-path from ice-9 to C
8035 code, so we can use the load-path to find the ice-9 boot code;
8036 this makes it easier to run Guile without installing it. See
8037 corresponding changes in guile/Makefile.in.
8038 * feature.c: Move stuff concerned with the load path to load.c.
8039 (scm_compiled_library_path): Deleted.
8040 Don't #include libpath.h here.
8041 * feature.h: Don't mention scm_compiled_library_path.
8042 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
8043 <sys/stat.h>, and <unistd.h> (if present).
8044 (R_OK): #define if the system hasn't deigned to.
8045 (scm_loc_load_path): New variable.
8046 (scm_init_load_path, scm_sys_search_load_path,
8047 scm_sys_try_load_path): New functions.
8048 (scm_init_load): Initialize scm_loc_load_path to point to the
8049 value cell of the Scheme %load-path variable.
8050 * load.h: Add declarations for scm_sys_search_load_path,
8051 scm_sys_try_load_path.
8052 * init.c: Call scm_init_load_path.
8053 * Makefile.in (feature.o, load.o): Dependencies updated.
8055 * load.c, load.h: Rewrite using PROTO macro.
8057 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8059 * gc.c (scm_cellp): New function: C predicate to determine if an
8060 SCM value can be regarded as a pointer to a cell on the heap.
8062 * gc.h: Added declaration of scm_cellp.
8064 * gdb_interface.h: New file: The GDB interface header from the GDB
8067 * gdbint.c: New file: GDB interface.
8069 * gdbint.h: New file: GDB interface.
8071 * libguile.h: Added #include <libguile/gdbint.h>.
8073 * init.c (scm_boot_guile): Added scm_init_gdbint.
8075 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
8076 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
8077 found if object files and source are kept separate).
8079 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8081 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8083 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8085 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8086 TK_SRC_DIR; they're not relevant any more.
8088 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8089 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8091 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8093 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8094 search path, so we can find the <libguile/MUMBLE.h> headers.
8096 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8098 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8099 implicit in the .c.o rule.
8100 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8103 Put the library path in a header file, instead of passing it on
8104 the command line in every compilation.
8105 * Makefile.in (libpath.h): New target.
8106 (feature.o): Depend on libpath.h.
8107 (clean): Delete libpath.h.
8108 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8109 * feature.c: ... #include "libpath.h" here.
8110 * .cvsignore: Ignore libpath.h.
8112 Don't install the unwashed masses of Guile header files in the
8113 main #include path; put most of them in a subdirectory called
8114 'libguile'. This avoids naming conflicts between Guile header
8115 files and system header files (of which there were a few).
8116 * Makefile.in (pkgincludedir): Deleted.
8117 (innerincludedir): New variable; this and $(includedir) are enough.
8118 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8119 (installed_h_files): Divide this up. Now this variable lists
8120 those header files which should go into $(includedir) (i.e. appear
8121 directly in the #include path), and ...
8122 (inner_h_files): ... this new variable says which files appear in
8123 a subdirectory, and are referred to as <libguile/mumble.h>.
8124 (h_files): List them both.
8125 (install): Create innerincludedir, not pkgincludedir. Put
8126 the installed_h_files and inner_h_files in their proper places.
8127 (uninstall): Corresponding changes.
8128 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8129 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8130 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
8131 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
8132 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
8133 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8134 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8135 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8136 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8137 vports.h, weaks.h: Find __scm.h in its new location.
8138 * __scm.h: Find scmconfig.h and tags.h in their new locations
8139 (they're both "inner" files).
8141 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8143 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8145 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8147 * posix.c: Doc fixes.
8149 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8151 * socket.c: Don't include a prototype for inet_aton; just use a
8152 K&R style declaration, to avoid warnings but minimize the chance
8153 of conflicts with the system.
8155 On NextStep, <utime.h> doesn't define struct utime, unless we
8156 #define _POSIX_SOURCE before #including it.
8157 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8158 * acconfig.h: New comment text for above CPP symbol.
8159 * configure.in: Call it.
8160 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8162 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8164 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8165 testing for __EMX__.
8167 * posix.c: #include <libc.h>, if it exists.
8169 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8170 don't even know if the latter exists.
8172 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8173 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8174 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8176 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8178 (scm_init_posix): Use them when initializing the Scheme constants
8181 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8183 * Makefile.in (libdir, includedir, bindir): Use the
8184 autoconf-supplied values, instead of deriving them ourselves.
8185 (pkgincludedir, datadir, pkgdatadir): New variables.
8186 (install, uninstall): Put the header files in a special
8187 subdirectory, not in the main search path.
8189 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8190 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8192 * Makefile.in (IMPLPATH): Deleted; never used.
8194 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8195 on the Tcl/Tk source any more.
8196 (INCLUDE_CFLAGS): Remove references to the above.
8198 * Makefile.in (version.o): Corrected dependencies.
8200 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8202 * libguile.h: #include "version.h"
8204 * init.c (scm_boot_guile): Call scm_init_version.
8205 * gscm.c (gscm_run_scm): Call scm_init_version.
8207 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8208 GUILE_VERSION): AC_DEFINE these.
8209 (acconfig.h): #undef the above symbols.
8211 * Makefile.in (libobjs): Add version.o.
8212 (installed_h_files): Add version.h.
8213 (c_files): Add version.c.
8214 (gen_c_files): Add version.x.
8215 (version.o): New rule.
8216 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8217 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

8226 weaks.o): Add version.h to dependency lists.
8227 (markers.o): Remove duplicate rule.
8229 * version.h: New file.
8231 * version.c: New file.
8233 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8235 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8236 array; use it appropriately. Since GCC is quite happy to
8237 subscript functions, it never warned us about this; we should use
8238 -Wpointer-arith in the future. I guess we never tested
8241 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8243 * socket.c: Doc and copyright fixes.
8245 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8247 * debug.c: Fixed and improved gdb support.
8249 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8251 * socket.c: Added declaration of inet_aton to avoid compiler
8252 warning. (Hope this solution is correct.)
8254 * stime.c: Added declaration of ftime. (This is missing in
8257 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
8259 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8261 * Makefile.in (c_files): add strerror.c.
8263 * strerror.c: new file from Emacs' sysdep.c.
8264 maybe configure should also check for sys_errlist.
8266 * configure.in (AC_REPLACE_FUNCS): add strerror.
8268 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8270 * debug.c (scm_init_debug): Added initialization for
8271 scm_evaluator_traps.
8273 * debug.h, debug.c: Various name changes.
8274 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
8275 "debug-options-interface". See commentary in options.c.
8277 * options.h, options.c: Options now have documentation strings.
8278 Also added a long explanatory commentary.
8280 * eval.c, print.h, print.c, read.h, read.c: Modifications to
8283 * gscm.c, init.c, root.c, throw.c: Bug fixes:
8284 last_debug_info_frame is now updated in all cases.
8286 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
8289 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8291 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
8292 Added option STACK_CHECKING.
8294 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8296 * Makefile.in: Added {debug,options,srcprop}.{h,c}
8298 * __scm.h: Removed symbols for debugging support.
8300 * acconfig.h: Added symbols for debugging support.
8302 * configure.in: Added user option for debugging support.
8303 --enable-debug will include the debugging code into libguile.a.
8305 * continuations.c (scm_make_cont): Enlarged the #if 0 around
8306 scm_relocate_chunk_to_heap.
8308 * debug.c: New file: low-level debugging support. It also
8309 includes support for debugging with gdb. (The extensions to gdb
8310 are written by Per Bothner at Cygnus.)
8312 * debug.h: New file: low-level debugging support.
8314 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
8315 argument pairs. Extensive modifications to the debugging
8316 evaluator. Added "SECTION:" commentaries to clarify what happens
8317 when, during double compilation. Renamed EVALIMP --> EVALIM.
8318 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
8319 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
8320 the beginning of the file. New procedure: scm_unmemocopy.
8321 Added some global state variables needed by the debugging
8322 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
8323 check_entry, check_apply, check_exit, debug_options and
8324 evaluator_traps. New acro: undefine.
8326 * eval.h: Renamed EVAL --> XEVAL.
8328 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
8329 --> scm_make_weak_key_hash_table.
8331 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
8332 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
8334 * libguile.h: Conditionally include debug.h
8336 * objprop.c (scm_object_properties, scm_set_object_properties_x):
8337 scm_object_properties shouldn't return handle. `handle' now gets
8338 initialized in scm_set_object_properties_x. scm_object_properties
8339 doesn't any longer create an entry in scm_object_whash.
8341 * options.c: New file: handling of run time options.
8343 * options.h: New file: handling of run time options.
8345 * posix.c (scm_getpgrp): Cast pointer to getpgrp.

8366 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8368 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
8370 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8372 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8373 and should be called by the final client.
8375 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8377 * gc.h: Use the PROTO macro when declaring functions.
8378 * gc.c: Use the PROTO macro when declaring static functions.
8379 Remove the CPP hair around function definitions.
8381 * gc.c (scm_init_storage): Initialize scm_asyncs.
8383 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8384 preprocessor symbol; "__scm.h" is where it might get #defined.
8385 * __scm.h: Similar: #include <scmconfig.h> before testing
8388 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8390 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8392 * init.c (scm_boot_guile): Add init_func argument; call
8393 (*init_func) instead of calling scm_appinit; it's ucky to
8394 hard-code names for the user's procedures.
8395 * init.h (scm_boot_guile): Adjust declaration.
8397 * __scm.h (PROTO): New macro, for declaring functions with
8400 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8401 eliminate all the __STDC__ conditionals.
8402 (scm_boot_guile): Add declaration.
8403 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8404 Remove __STDC__ conditionals around function definitions; the
8405 declarations in init.h will provide the same information, more
8408 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8409 complain about it in the error message; the error message is
8410 adequate without that note, and there's nothing the user can do
8413 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8415 * Makefile.in (ancillary): Drop def.sed.
8417 * posix.c (scm_init_posix): Use numeric values, rather than
8418 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8419 F_OK. The symbols aren't available on some systems, and I'm
8420 pretty sure their values are fixed by common widespread practice.
8421 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8423 More functions unavailable on some systems.
8424 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8425 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8427 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8428 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8429 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8430 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8431 stub that signals an error as the #else.
8433 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8435 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8437 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8439 * unif.c: include ramap.h.
8441 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8443 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8445 * ports.c: include sys/ioctl.h.
8447 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8449 * configure.in: check for sys/ioctl.h.
8451 * ports.c: include <malloc.h> not "malloc.h".
8453 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8455 * fports.c: remove ttyname and tmpnam declarations.
8457 * posix.c: fewer ttyname declarations.
8459 * fports.c: include <string.h> not "string.h".
8461 * init.c, ioext.c: include string.h and unistd.h.
8463 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8465 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8466 genio.c, simpos.c, vports.c: include string.h.
8468 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8470 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8472 (scm_addr_buffer_size): change type from scm_sizet to int.
8473 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8474 from scm_sizet to int.
8476 * error.c: include unistd.h.
8478 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8481 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8483 * __scm.hd, def.sed: deleted.
8485 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8487 Changes for NeXT, suggested by Robert Brown.
8488 * configure.in: Call AC_TYPE_MODE_T.
8489 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8490 NeXT. Put header file list in alphabetical order.
8491 * configure, scmconfig.h.in: Regenerated.
8492 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8494 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8497 * acconfig.h: New file, providing documentation for the CPP
8498 symbols defined in configure.in
8499 * acconfig-1.5.h: Removed; superceded by the above.
8501 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8503 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8505 * fports.c (scm_open_file): don't return #f, throw error.
8507 * ioext.c (fileno): renamed from %fileno.
8508 (soft-fileno): deleted.
8510 * ports.c (scm_port_revealed): don't need to check for -1 from
8512 (scm_set_port_revealed_x): return unspecified, not #f.
8514 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8516 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8518 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8520 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8522 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8524 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8525 This is necessary on Ultrix, and doesn't hurt portability.
8527 * Makefile.in (dist-dir): New target, implementing a new dist system.
8528 (installed_h_files): Put in alphabetical order.
8529 Remove duplicate entries for markers.h and unif.h.
8530 (c_files): Remove duplicate entries for markers.c.
8531 (ancillary): Renamed from anillery; all uses changed. Remove
8532 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8533 Remove all the ../doc/* files; doc/Makefile.in handles that.
8535 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8537 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8538 every if must have an else, or else the whole command has a
8539 non-zero exit code whenever the if's condition is false.
8541 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8543 * posix.c: include string.h.
8545 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8547 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8550 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8551 Remove leading % from scheme names.
8552 Do not return error values, call SCM_SYSERROR or similar.
8554 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8556 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8558 * struct.c (scm_init_struct): new file.
8560 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8562 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8563 (scm_list_head): added list-head for rapidly chopping argument
8564 lists off of longer lists (and similar).

8569 handle for obj, not the handle itself.
8571 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8573 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8574 weak hash tables last of all marking to avoid an obscure gc bug.
8575 WARNING: circular lists stored in a weak hash table will hose us.
8577 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8579 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8580 new functions similar to scm_substring_move_left_x and
8581 scm_substring_move_right_x.
8583 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8585 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
8588 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
8590 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8592 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8594 * strports.c (scm_strprint_obj): convenience function. C for
8595 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8597 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8598 removed to a separate library
8600 * init.c (scm_boot_guile): copied from guile-tcl.c.
8601 Initialization specific to tcl interpreters removed.
8603 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8605 * ports.c (scm_ports_prehistory): size malloced here doesn't
8606 matter so long as it is non-0 (got rid of "* 4").
8608 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8610 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8611 since its definition was bogus).
8613 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8615 * mallocs.[ch]: back again (for rx at least).
8617 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8619 * ports.c: removed functions relating to the mapping between ports
8620 and descriptors. (That stuff is unix-specific and should be collected
8621 in a separate library).
8623 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
8624 (Tom Mckay@avanticorp.com)
8626 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
8628 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8629 handled correctly (SCM_FREEP was applied to them) -- test for
8630 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
8631 being overwritten with #f. (brown@grettir.bibliotech.com)
8633 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>

8655 * gscm.c (gscm_run_scm): got rid of objprop.
8657 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>

8662 * procprop.c (scm_stand_in_scm_proc):
8663 NOTE: don't use a alist here.
8664 (scm_set_procedure_properties_x): fix type checking throughout this file.
8666 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
8668 * ports.c (scm_remove_from_port_table): adjust scm_mallocated

8674 * vports.c (scm_make_soft_port): allocate a port table entry
8675 (possibly triggering gc) before setting the tag of the corresponding
8678 * pairs.c (scm_delq_x): never throw an error.
8680 * vectors.c (scm_make_vector): made the default vector fill argument
8681 into '() (much more useful than the previous value, "#unspecified")
8683 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
8685 * ports.c (scm_add_to_port_table): Added fields
8686 to port table entries: file_name, line_num, col.
8687 Update these in open_file, gen_getc and gen_ungetc.
8688 Added procedures to access those fields.
8690 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
8692 * procs.c (scm_make_subr_opt): new entry point for making
8695 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
8697 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
8699 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
8701 * numbers.c (scm_exact_p): This function no longer
8702 implements "integer?".
8704 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
8706 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
8707 (scm_gc_stats): return an assoc of useful data. Replaces "room"
8708 and the stats reporting formerlly built into repl.
8710 * repl.[ch]: removed.
8711 GC statistics keeping moved to gc.c.
8712 Other statistics keeping can be done from Scheme.
8713 REPLS are now written in Scheme.
8715 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
8717 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky

8720 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
8722 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
8724 * feature.c (scm_compiled_library_path): moved here from repl.c.
8725 This file is for stuff relating specifically to Scheme libraries
8728 * eval.c (scm_m_define): don't give warning about redefinition, don't
8731 NOTE: this should throw a resumable exception with parameters --
8732 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
8734 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
8736 * error.c: scm_warn eliminated.

8748 between the call to procedurep and use.
8750 * error.c (scm_everr):
8752 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
8755 * strports.c: don't reveal the port's string to the caller
8756 because it changes size.
8758 (stputc stwrite): check/change the strings length with interrupts
8761 * objprop.c (scm_set_object_property_x &c): use the generic
8762 hashing functions and be threadsafe.
8764 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
8765 (per suggestion jaffer@gnu.ai.mit.edu).
8767 * mbstrings.c (scm_multi_byte_string): guard against argument list
8770 * strings.c (scm_make_string): loop cleanup
8772 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer

8798 initialization to fix a race condition.
8800 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
8801 object, not in a global.

8824 set the multi_byte flag correctly in symbols. This is wrong.
8825 intern_obbary_soft and msymbolize should take an extra parameter.
8826 Also, weird multibyte symbols don't print correctly.
8827 The weird symbol syntax is also a bit bogus (emacs doesn't quite
