1 1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
3 * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
6 * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
8 1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
10 * numbers.c: Converted comparison operations to dispatch on
11 generic if args don't match.
13 * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
15 1999-09-06 James Blandy <jimb@mule.m17n.org>
17 * guile-snarf.c: Deleted. Snarfing should respect CPP
18 conditionals, so it needs to actually run CPP. Bleah.
20 1999-09-05 James Blandy <jimb@mule.m17n.org>
22 Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
23 * guile-snarf.in: Be sure to exit with an error if CPP does.
24 * Makefile.am (.c.x): Delete the .x file and exit with an error
25 status if guile-snarf exits with an error status.
26 * Makefile.in: Regenerated.
28 * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
29 scm_makekey, which doesn't exist any more. Guess nobody's using
32 * guile-snarf.c: New implementation of guile-snarf, meant to be
33 more robust than the shell script. I think it's complete, but I
34 haven't tested it at all, and I haven't changed the build process
35 to actually use it. We should compare its output against that of
36 the existing shell script, for all source files.
38 * guile-snarf.c (parse_args): Abort if we haven't handled some
41 1999-09-03 James Blandy <jimb@mule.m17n.org>
43 * load.c (scm_search_path): If the filename has any extension at
44 all, ignore the entire list of extensions. Also, don't check whether
45 the file is accessible. If the file exists, accessible or not, we
46 should return it. Inaccessible files should cause an error later.
47 (Thanks to Keisuke Nishida for the suggestions.)
49 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
51 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
52 atexit not available. (sunos4.1.4 needs it.)
54 1999-09-01 James Blandy <jimb@mule.m17n.org>
56 I take it all back --- bcopy does handle overlapping source and
57 destination areas correctly. At least on every system I could
58 find. But it is better to use AC_REPLACE_FUNCS than to introduce
60 * memmove.c: New file, implementing memmove in terms of bcopy.
61 * scmconfig.h.in: Regenerated.
63 Allocators should use the `void *' type for generic pointers.
64 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
65 argument and return types.
66 * gc.h: Corresponding changes to prototypes.
69 1999-08-31 James Blandy <jimb@mule.m17n.org>
71 * numbers.c (scm_init_numbers): Claim to support the `complex'
72 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
74 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
75 find (ice-9 boot-9) when Guile was compiled in a separate
76 directory from the source. (Thanks to Rodney Brown.)
77 * Makefile.in: Regenerated.
79 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
80 table lengths by the size of a single element when growing the
81 table. (Thanks to Bill Schottstaedt.)
83 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
85 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
86 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
87 since that cuts down the time for type dispatch by 50%.
89 1999-08-30 James Blandy <jimb@mule.m17n.org>
91 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
92 not a correct substitute for memmove, because it doesn't handle
93 overlapping source and destination areas on many platforms.
94 Overlaps are the primary reason to use memmove in the first place.
95 * ports.c (scm_ungetc): Same.
96 * strop.c (scm_substring_move_x): Same.
98 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
100 * gc.c (scm_init_storage): Skip registration of cleanup on systems
101 which lack atexit. (Is it important that cleanup is made
102 properly? Maybe we should replace all `exit' with `scm_exit' and
105 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
106 scm_struct_free_standard, scm_struct_free_entity): Declared to
107 return scm_sizet instead of size_t.
109 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
110 there on sunos4.1.4.)
112 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
114 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
115 Account for the case when second argument is unbound.
117 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
118 (Thanks to Karoly Lorentey.)
120 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
121 isn't present. (Thanks to Suzuki Toshiya.)
123 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
126 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
129 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
130 Bernard Urban and Ian Grant.)
132 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
133 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
134 change in the representation of entities and operators.)
136 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
138 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
139 don't allocate zero bytes (thanks to Bill Schottstaedt).
141 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
143 * procs.c (scm_setter): Converted to use generic dispatch.
145 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
148 * load.c (scm_search_path): Don't try extensions which already are
149 present at the end of the filename.
150 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
152 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
154 Cleanup and simplification of generic method dispatch.
155 Also, the quadruple representation of entity and operator
156 procedures has been replaced with single.
158 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
160 * print.c (scm_isymnames): Removed #@hash-dispatch.
162 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
163 from eval.c; Support 0 arity methods.
164 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
165 (scm_apply_generic_env): Removed.
166 Replaced slots proc0-3 with procedure.
168 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
169 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
170 SCM_OPERATOR_PROCEDURE.
171 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
172 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
174 * struct.c, struct.h: Replace 4 procedure slots with one.
175 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
177 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
180 * eval.c (scm_sym_args): Removed.
181 (SCM_CEVAL): Simplified entity application.
182 Moved dispatch code to objects.c.
184 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
186 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
188 * sort.c (closureless): Use scm_eval_body.
190 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
191 with a symbol as last form was first called normally and then via
192 `map' or some other mechanism using primitive apply, an ILOC was
195 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
197 This change extends the representation of primitive procedures
198 with more data fields, e.g. a place for documentation and true
199 procedure properties.
201 * procs.c, procs.h (scm_subr_entry): New type: Stores data
202 associated with subrs.
203 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
204 SCM_SUBR_DOC): New macros.
205 (scm_subr_table): New variable.
206 (scm_mark_subr_table): New function.
208 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
210 * gc.c (scm_gc_mark): Don't mark subr names here.
211 (scm_igc): Call scm_mark_subr_table.
214 This change implements a scheme for letting a generic work as a
215 shadow for a primitive procedure. If the primitive procedure
216 can't dispatch on its arguments, control is left over to the
217 generic. Normal wrong type arg errors will be generated until the
218 user has hung the first method on the primitive.
220 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
222 * procs.c, procs.h (scm_subr_p): New function (used internally).
224 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
226 * objects.c, objects.h (scm_primitive_generic): New class.
228 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
230 * print.c (scm_iprin1): Print primitive-generics.
232 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
233 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
235 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
236 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
237 primitives). NOTE: This means that it is now *required* to use
238 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
239 obscured representation that will be removed in the future anyway,
240 so backward compatibility is no problem here).
242 * numbers.c: Converted most numeric primitives (all but bit
243 comparison operations and bit operations) to dispatch on generic
247 Better support for applying generic functions.
249 * eval.c, eval.h (scm_eval_body): New function.
251 * objects.c (scm_call_generic_0, scm_call_generic_1,
252 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
256 Optimization of the generic function dispatch mechanism.
258 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
259 called scm_memoize_method instead of doing a second lookup.
261 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
266 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
267 scm_sysintern so that the binding connected with the subr name
268 isn't cleared when we give set = 0.
271 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
273 More transparent handling of ports with print states.
275 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
276 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
277 instead of a pair of a port and a print state. We'll need to cons
278 once extra in scm_printer_apply but the type system will be
279 cleaner, it will mix better with GOOPS, and, it will be even more
280 transparent to the user.
282 * print.c (scm_get_print_state): New procedure: Given an output
283 port, return the print state associated to it in the current print
284 chain, if one exists;
285 (scm_port_with_print_state): New procedure: Associate a
286 print-state with a port.
287 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
288 (scm_printer_apply): Wrap port and pstate as a smob;
289 (print_state_printer): Removed.
291 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
293 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
296 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
297 testing (otherwise the port-print-state trick won't be transparent
298 to the user; one example where this caused problems was in the
299 (ice-9 format) module).
301 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
303 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
304 SCM_UNSPECIFIED instead of the set value.
306 1999-08-20 James Blandy <jimb@mule.m17n.org>
308 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
310 * ports.h (enum scm_port_rw_active): New enum, containing
311 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
312 zero). The debugger knows about enums, but doesn't know about
314 (typedef scm_port): Declare rw_active member to be an enum
316 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
318 * ports.c (scm_add_to_port_table): Same.
319 * strports.c (st_flush, st_end_input): Same.
321 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
322 scm_must_realloc, and scm_done_malloc as appropriate.
324 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
326 * sort.c (quicksort): Added condition to protect the algorithm
327 from crashing the interpreter if the less predicate is buggy.
329 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
331 * fports.c (fport_write): fix line-buffering mode again.
332 (scm_open_file): recognise 'l' for line-buffering.
333 (scm_setvbuf): recognise _IOLBF for line-buffering.
335 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
337 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
340 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
343 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
345 * fports.c (fport_write): use memcpy instead of strncpy, in case
346 the data contains NUL.
348 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
350 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
352 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
353 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
354 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
355 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
356 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
357 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
358 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
359 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
360 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
361 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
362 scm_sym_ as prefix for symbols.
364 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
366 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
367 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
368 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
369 scm_sym_atcall_cc): Made global.
371 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
373 * eval.c (scm_sym_args): Made global.
375 * objects.c (scm_set_object_procedure_x): Disallow setting of
376 procedures for pure generic functions.
378 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
380 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
381 Scheme name from lseek to seek, but lseek was added recently so
382 it shouldn't be a big problem.
383 * ports.c, gdbint.c, ioext.c: changed callers.
385 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
387 * fports.c (fport_input_waiting): if select is used, return 1
388 instead of whatever FD_ISSET expands to. maybe it will be useful
389 to interpret the value from the input_waiting ptob procedure as a
390 lower bound on the number of bytes available.
392 * Mikael asked for a few names to be changed...
394 * ports.c (scm_make_port_type): take the write procedure as the
395 second argument instead of the flush procedure.
396 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
397 fflush -> flush, read_flush -> end_input, fclose -> close,
398 fill_buffer -> fill_input, ftruncate -> truncate,
399 input_waiting_p -> input_waiting.
401 * ports.c (end_input_void_port): was read_flush_void_port.
402 (scm_set_port_end_input): was scm_set_port_flush_input.
403 (scm_set_port_flush): was scm_set_port_write.
404 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
405 (scm_end_input): was scm_read_flush.
406 (scm_fill_input): was scm_fill_buffer.
407 (scm_flush): was scm_fflush.
408 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
409 (fport_end_input): was local_read_flush.
410 (fport_flush): was local_fflush.
411 (fport_close): was local_fclose.
412 (fport_truncate): was local_ftruncate.
413 (fport_seek): was local_seek.
414 (fport_free): was local_free.
415 (fport_fill_input): was fport_fill_buffer.
416 * strports.c (st_end_input): was st_read_flush.
417 (st_truncate): was st_ftruncate.
418 * vports.c: (sf_flush): was sfflush.
419 (sf_close): was sfclose.
420 (sf_fill_input): was sf_fill_buffer.
422 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
425 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
427 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
428 forms now contain the expressions to be dispatched upon instead of
429 depending on a surrounding lambda or let; Generic function
430 dispatch has been optimized; `apply' on a generic function now
431 works a little bit strangely. It uses a trick so that the type
432 dispatch code in SCM_CEVAL can be reused.
434 * objects.h, objects.c (scm_apply_generic_env): Added (used by
436 (scm_operator_p): Added.
437 (scm_sym_atdispatch): Added.
438 (scm_set_object_procedure_x): Modified to handle the new style
440 (scm_object_procedures): New debugging procedure.
442 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
444 * eval.c, eval.h (scm_sym_args): Added.
446 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
448 * feature.c, feature.h (scm_c_run_hook): Added.
450 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
451 cdrxnoap and loopnoap instead of begin and loop.
453 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
455 * ports.c (scm_putc, scm_puts),
456 * unif.c (scm_uniform_array_write): use scm_lfwrite.
457 * ports.c (scm_putc): change type of first argument from int to char.
459 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
461 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
462 SCM_IM_HASH_DISPATCH.
464 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
465 (scm_si_redfined, scm_si_hashsets): Moved.
467 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
468 flag which combines type and status info so that the class
469 redefinition protocol has zero cost during normal execution.
471 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
473 * ports.h (scm_ptob_descriptor): include a write procedure again.
474 it's more efficient for unbuffered fports (e.g., sockets.)
476 * ports.c (scm_puts): use ptob->write.
477 * vports.c (scm_make_sfptob): set write proc in ptob.
478 * strports.c (scm_make_stptob): set write proc in ptob.
479 * ports.c (write_void_port): new procedure.
480 * vports.c (sf_write): new procedure.
481 * ports.c (scm_lfwrite): use ptob->write.
482 * strports.c (st_write): new procedure.
483 * fports.c (fport_write): new procedure.
484 (scm_make_fptob): set write in ptob to fport_write.
485 * ports.h: prototype for scm_set_port_write.
486 * ports.c (scm_make_port_type): initialise ptob write procedure.
487 (scm_set_port_write): new proc.
489 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
491 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
492 until we've verified that it is actually a port. (Thanks to
495 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
497 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
498 code, particularly an unnecessary test (len != size, where len ==
499 size). (Was this leftovers from debugging code, or have I missed
502 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
503 size. (Thanks to James Dean Palmer.)
505 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
506 (Thanks to Lorentey Karoly.)
508 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
510 * eval.c (scm_m_expand_body): Use scm_cons_source.
512 * struct.c (scm_print_struct): Use vtable name.
514 * print.c (scm_init_print): Set name of print state type.
516 * stacks.c (scm_init_stacks): Set name of stack type.
518 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
520 * eval.c (SCM_CEVAL): Removed old implementation of internal
523 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
525 * debug.c, debug.h (scm_reverse_lookup): Added.
526 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
527 internal procedure definitions; Don't use scm_i_inner_name.
529 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
532 * eval.h: Added prototypes for multi language support functions.
534 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
535 improper lists in the low-level representation, since that will
536 cause a begin to be prepended at macro expansion.
538 * eval.c (scm_cons_source): Version of cons which copies source
539 properties from an existing cell.
540 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
542 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
543 procedure source before calling scm_unmemocopy instead of faking
546 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
548 Ported `internal defines' fix from SCM. Original ChangeLog entry:
550 1998-07-09 Radey Shouman <radey@colorage.com>
552 * eval.c (ceval_1): Modifications to allow rewriting of interal
553 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
554 body of which it is the CAR is macro expanded by m_expand_body,
555 which rewrites internal DEFINE.
557 (m_expand_body): Added.
559 (m_macroexp1): Added argument to control error checking:
560 m_expand_body may speculatively expand forms in the wrong
561 environments. Made argument number checks conditional on
564 (m_body): Added, error checks bodies and inserts the ISYM tokens.
566 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
569 (m_cond): (m_case): (m_quote): Modified to avoid destructively
570 changing their argument forms. Since m_expand_body
571 speculatively macro expands forms the process must be
574 (m_ident_eqp): Fixed to use proper environment.
576 (renamed_ident): Added DEFER_INTS_EGC.
578 Added prototypes for static functions.
584 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
585 is false, do not produce an error for unbound variables, return a
586 pointer to cell_undef instead.
588 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
592 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
593 destructively changing their argument forms. Since m_expand_body
594 speculatively macro expands forms the process must be reversible.
596 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
597 SCM_IM_LET introduced by named lets.
599 (scm_m_letstar): Use scm_m_body instead of bodycheck.
601 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
602 scm_letrec. scm_letrec1 does not check for a null binding and
603 takes an additional argument to specify the ISYM of the body. Use
604 scm_m_body instead of bodycheck.
606 (scm_m_let): Use scm_m_body instead of bodycheck.
608 (scm_m_expand_body, scm_macroexp): New.
610 (unmemocopy): Account for ISYMs introduced by scm_m_body.
612 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
613 check=1. Throw error for internal defined that have not been
614 rewritten by scm_m_expand_body.
616 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
617 Removed prototype for SCM_APPLY.
619 * tags.h: Added extern declaration of scm_isymnames.
621 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
623 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
625 * lang.c: New file: Beginning of multi-language support.
627 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
629 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
630 (scm_dynamic_wind): Added argument checking for the after guard so
631 that we don't add garbage on the dynwind chain.
632 (scm_swap_bindings): Added.
634 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
635 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
636 (scm_isymnames): New isyms for multi-language support.
638 * eval.c (scm_nil, scm_t): New symbols.
639 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
640 forms for multi-language support.
642 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
644 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
646 Renamed functions in the random function library interface
647 from scm_i_XXX --> scm_c_XXX.
649 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
651 * ports.c (scm_putc): fix line-buffering.
653 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
655 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
656 scm_set_ptob_XXX --> scm_set_port_XXX.
658 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
660 * ports.c, ports.h (scm_make_port_type): New interface for
661 creation of port types (replaces scm_newptob). Just as for the
662 smobs, we need to separate the internal representation of smob
663 types from the interface, so that we easily can add new fields and
664 rearrange things without caring about backward compatibility.
665 This change was forced by the need in GOOPS to create classes
666 representing port types.
667 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
668 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
669 scm_set_ptob_seek, scm_set_ptob_truncate,
670 scm_set_ptob_input_waiting_p): New setters.
671 (scm_newptob): Rewritten to use scm_make_port_type. For backward
673 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
674 (scm_prinport): Removed.
675 (scm_port_print): Added.
676 (scm_print_port_mode): Added.
677 (void_port_ptob, print_void_port, close_void_port, noop0):
678 Removed. Removed #include "genio.h" Added #include "objects.h",
681 * fports.c (prinfport): Moved code from ports.c.
683 (scm_fptob): Removed. Instead use new interface.
684 (scm_make_fptob): Added. (Need to create basic ports in a
685 specific order in ports.c.)
687 * strports.c (scm_stptob, prinstpt, noop0): Removed
688 (scm_make_stptob): Added.
690 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
691 (scm_make_sfport): Added.
693 * filesys.c (scm_dir_print): Don't use the port printing code.
694 Instead provide specific directory printer.
696 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
698 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
701 * smob.c (scm_smob_print): Handle non-existing type name nicely.
702 Removed #include "genio.h"
704 * objects.c (scm_make_port_classes): New function ptr.
706 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
708 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
710 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
711 allow the 1st argument to be a fdes or filename as well as a
712 port (as in the filesys.c version).
714 * filesys.c (scm_truncate_file): removed.
716 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
718 * readline.c, readline.h: Removed.
720 * objects.c, objects.h (scm_port_class): Added.
721 (scm_class_of): Look up port class in scm_port_class.
722 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
723 SCM_INOUT_PCLASS_INDEX): Added.
726 * Makefile.am: Removed genio.c, genio.x.
730 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
732 * init.c: Make sure that scm_post_boot_init_modules is called only
733 once. (Important when using a dumped image.; Thanks to Bernard
736 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
738 * guardians.c (scm_guardian_zombify): Separate scanning for
739 zombies from marking the pairs of the free list.
741 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
742 use the macros. (Thanks to Michael Livshin.)
744 * eval.c (scm_m_lambda): Let bodycheck check the body of the
745 lambda. Let your sins be purified by the blood of the lambda.
746 (Thanks to Eric Hanchrow.)
748 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
749 (Thanks to Valdis Kletnieks.)
751 Fixes for EMX from Mikael Ståldal.
753 * filesys.c: #include <io.h>, if we have it.
754 * scmconfig.h.in: Regenerated.
756 * stime.c (ftime): Delete declaration for this function --- let
757 the system supply it.
759 Cleanups from John Bley.
761 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
763 * gsubr.c: Don't include "gsubr.h" twice.
765 Cleanups for compilation on Irix 6, from David Kaelbling.
767 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
768 regex_t pointer. This is what the callers have, mostly.
769 (scm_regexp_exec): Don't forget to pass the `rx' argument to
770 scm_regexp_error_msg.
772 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
773 int. That way, if we get a warning on this line, it's more likely
774 that we're really missing bits we care about.
776 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
779 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
780 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
781 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
782 cast at all is more appropriate in every case. At the moment, we
783 assume everywhere that SCM is an integral type anyway.
785 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
787 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
788 read_pos after scm_fill_buffer.
790 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
793 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
794 fports.c (fport_fill_buffer): implement the interface change.
796 * ports.c (scm_fill_buffer): interface change: no longer increments
797 read_pos past the character that's returned. it seems clearer to
798 leave it to the caller to decide what to do (thanks Jim).
800 * vports.c (sf_fill_buffer): put the read char into the buffer
801 as well as returning it.
803 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure

808 * strports.c (scm_strprint_obj): simplify. start with initial
810 (st_seek): don't allow string to be extended if seeking past
811 the end of a read-only port.
813 1999-07-12 Gary Houston <ghouston@easynet.co.uk>
815 * strports.c (st_seek): change the resize checks.
817 * ports.c (scm_ftruncate): throw error if offset works out negative.
819 * strports.c (st_flush): increase string size in blocks of
820 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
821 it's greater and reset read_buf_size.
822 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
823 to be maintained for output ports too (it holds the written
824 part of the string, while write_buf may have unwritten buffer
826 (st_truncate): rewritten.
827 (top of file): added a few notes.
829 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
831 Patch from Greg Badros:
832 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
833 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
834 (function pointer) argument to scm_make_gsubr and scm_make_subr
835 calls. This avoids warnings in C++ programs using guile-snarf.
837 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
839 * strports.c (st_grow_port): set pt->read_pos. set
840 pt->read_buf_size one less than pt->write_buf_size if there's
841 an unwritten char at the end of the string. similarly for
843 (st_resize_port): renamed from st_grow_port.
844 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
845 seek from read_end instead of write_end for SEEK_END.
846 (st_ftruncate): calculate current length using readbuf, not write

854 (scm_call_with_output_string, scm_strprint_obj): use
855 scm_strport_to_string.

858 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
860 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)

866 and "bigneg" smob types.
868 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
869 SCM_RETURN_NEWSMOB macro. Added protos for new functions in
872 * *.c: Use scm_make_smob_type_mfpe, instead of scm_newsmob, and
873 use SCM_NEWSMOB or SCM_RETURN_NEWSMOB in constructors instead of
874 SCM_NEWCELL and setting the CAR/CDR by hand.

958 trinary conditional in order for the flag computation to be
961 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
963 * struct.c, struct.h:
965 In order to support different kinds of deallocation, a destructor
966 slot has been added to struct vtables. This allows for structs
967 containing pointers to other memory blocks.
969 (scm_struct_i_free): New hidden struct slot. Holds destructor for
970 instances to this vtable.
971 (scm_struct_free_0): New destructor: Doesn't deallocate data.

1041 * eq.c, eval.c, list.c, ramap.c, vectors.c: Always write parens
1042 around the condition of an `if', `while', etc., even if the

1044 surrounded by parens. It's more readable.
1046 * eval.c (scm_map, scm_for_each): Verify that all arguments are
1047 proper lists, and of the appropriate lengths.
1048 (check_map_args): New function. (Thanks to Greg Harvey for the

1070 (scm_igc): Check for underflow by seeing if this is negative.
1072 * gc.h (scm_mallocated): Fix declaration.
1073 (Thanks to Greg Harvey.)

1084 vector contents, to be used only during garbage collection.
1085 * weaks.h (SCM_WVECT_GC_CHAIN): New macro to access it.
1086 * gc.c (scm_weak_vectors): Now a SCM instead of a SCM*, and now
1088 (scm_weak_size, scm_n_weak): Deleted.
1089 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
1090 vectors without allocating new storage during GC, using
1091 scm_weak_vectors as the head of the chain.
1092 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1093 instead of stepping through an array.
1094 (scm_gc_sweep): Update offset used to find start of weak vector to
1096 (scm_init_storage): Set scm_weak_vectors to EOL.
1098 Fix from Ken Raeburn <raeburn@raeburn.org>:
1099 * gc.c (already_in_gc): New variable.
1100 (scm_igc): Set and clear already_in_gc; abort if it's set at
1103 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
1105 Fix from Gary Houston:
1106 * fports.c (local_seek): Signal an error if the seek fails.
1107 * ports.c (scm_lseek): Don't check return value of port's seek
1108 function; it's its job to signal an error if there's a problem.
1110 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>
1112 * strports.c (scm_call_with_output_string): Don't include the
1113 extra character at the end of the string in the result.
1115 * ioext.c (scm_read_line): Switch to reading properly.
1117 * fports.c, fports.h, gc.c, gdbint.c, ioext.c, ports.c, ports.h,
1118 scmsigs.c, strports.c, vports.c: Install the sources which
1119 actually correspond to the changes described below. I got the
1120 ChangeLog entries and the patch from two different places...
1122 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1124 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1125 it shows up as terrible performance, as we GC constantly.
1127 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
1128 newline. A bit faster, and definitely hairier.
1129 (scm_read_line): Count newlines here instead.
1131 * strings.c (scm_take_str): New function.
1132 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
1133 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use
1134 scm_take_str, to avoid copying the string.
1136 Add some simple-minded support for line buffered ports.
1137 * ports.h (SCM_BUFLINE): New flag for ports.
1138 * init.c (scm_init_standard_ports): Request line-buffering on
1139 the standard output port.
1140 * ports.c (scm_mode_bits): Recognize 'l' as a request for line
1142 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1143 and there's a newline to be written, flush the port.
1145 Gary Houston's open-buffer port patches:
1147 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1149 * ports.c: (scm_lseek): clear buffers even if just reading current
1152 * fports.c (local_fclose): call local_fflush unconditionally.
1153 (various): don't use the scm_must... memory procs.
1155 1999-04-25 Gary Houston <ghouston@easynet.co.uk>
1157 * ports.h (scm_port): make read_pos a pointer to const.
1158 strports.c: take care of rw_active and rw_randow.
1159 fports.c: scm_fport_drain_input: removed. do it all in ports.c.
1160 strports.c (scm_mkstrport): check that pos is reasonable.
1161 ioext.c (scm_ftell, scm_fseek): use lseek.
1162 (SCM_CLEAR_BUFFERS): macro deleted.
1163 ioext.c (redirect_port: use ptob fflush, read_flush.
1164 ports.h (scm_ptobfuns): add ftruncate.
1165 ports.c (scm_newptob): set ftruncate.
1167 ports.c (scm_ftruncate): new procedure.
1168 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.
1169 strports.c (st_seek, st_grow_port): new procs.
1170 fports.h (scm_port): change size types from int to off_t.
1171 ports.c (scm_init_ports): initialise the seek symbols here
1172 instead of in ioext.c.
1173 strports.c (scm_call_with_output_string): start with an empty
1174 string, so seek and ftruncate can be used.
1176 gdbint.c: adjust string port usage.
1178 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1180 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
1181 equivalent to fflush for the read buffer.
1182 * ports.c (scm_newptob): set read_flush.
1183 ports.c (void_port_ptob): set read_flush.
1184 fports.c (local_read_flush): new proc. add to ptob.
1185 strport.c (st_read_flush): likewise.
1186 vport.c (sf_read_flush): likewise.
1187 fports.h (struct scm_fport): remove random member. there's nothing
1188 left but fdes. leaving it as a struct to allow for future changes.
1189 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1190 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1191 ptob proc if the read buffer is filled.
1193 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1195 * ports.h (scm_port): add a rw_random member and replace
1196 reading and writing members with rw_active member.
1197 SCM_PORT_READ/SCM_PORT_WRITE: new values.
1199 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
1201 * ports.h (struct scm_port_table): add writing and reading members
1202 to replace write_needs_seek: it isn't good enough for non-fports.
1203 ports.c, ioext.c, fports.c: corresponding changes.
1204 (struct scm_port_table): give it a typedef and rename to scm_port.
1205 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
1206 corresponding changes.
1208 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
1210 * ports.c (scm_newptob): bugfix: set seek member.
1211 * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
1212 and generalised to all port types.
1214 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
1216 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
1217 signals (it was only being done for handlers installed from Scheme).
1218 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
1219 waiting for input caused an EINTR error from read.
1221 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
1223 * ports.h (struct scm_port_table): make all the char members
1224 unsigned, so they convert to int without becoming negative if large.
1226 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
1228 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
1229 with threads enabled. rename this procedure to
1230 fport_wait_for_input and take a port instead of a fdes.
1231 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
1233 * readline.c (scm_readline): Applied a patch from Greg Harvey to
1234 get readline support working again: use fdopen to get FILE objects.
1236 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
1238 * gc.c (scm_init_storage): install an atexit proc to flush the
1240 (cleanup): the new proc. it sets a global variable which can be
1241 checked by the ptob flush procs to avoid trying to throw
1242 exceptions during exit. not very pleasant but it seems more reliable.
1243 * fports.c (local_fflush): check terminating variable and if set
1244 don't throw exception.
1245 * CHECKME: that the atexit proc is installed if unexec used.
1247 * throw.c (scm_handle_by_message): don't flush all ports here.
1248 it still causes bus errors.
1250 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
1251 and move to ioext.c.
1253 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
1255 * ports.c (scm_char_ready_p): check the port buffer and call the
1256 ptob entry if needed.
1258 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
1259 ptob initialisers. use it in char-ready
1261 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
1263 * vports.c (sfflush): modified to write a char (since softports
1264 currently use shortbuf.)
1266 * fports.c (scm_standard_stream_to_port): moved to init.c and
1269 * init.c (scm_init_standard_ports): make stdout and stderr
1270 unbuffered if connected to a terminal. with stdio they
1271 were line-buffered by default.
1273 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
1276 * ports.h (scm_ptobfuns): change fflush return to void.
1277 change flush proc definitions.
1279 * strports.c (scm_call_with_output_string): get size from
1280 buffer instead of port stream.
1281 (st_flush): new proc.
1283 * ports.h (struct scm_port_table): added write_end member,
1284 as an optimisation. set it where write_buf_size is set.
1286 * ports.h (struct scm_port_table): change stream from void *
1287 back to SCM. SCM presumably must be large enough to hold a
1288 pointer (and probably vice versa but who knows.)
1289 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
1291 (scm_puts): rewritten
1292 * fports.c (local_ffwrite, local_fputs): removed.
1293 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)

1302 * ports.c (scm_add_to_port_table): initialise write_needs_seek.
1304 * ports.h (scm_ptobfuns): add seek function pointer.
1305 * fports.c: set it to local_seek, new procedure.
1308 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
1309 use ptob for seek. take ptob instead of fport arg.
1311 * ports.h (struct scm_port_table): new member write_needs_seek,
1312 replaces reading member in fport struct.
1314 * vports.c (sfgetc): store the getted char into the buffer.
1315 rename to sf_fill_buffer and install it for fill-buffer in ptob.
1316 the Scheme interface is still a procedure that gets a char.
1317 (scm_make_soft_port): set up the port buffer (shortbuf).
1319 * fports.c (local_fgetc, local_fgets): deleted.
1320 * strports.c (stgetc): likewise.
1321 * ports.c: scm_generic_fgets: likewise.
1323 * ports.h (scm_ptobfuns): add fill_buffer.
1324 * ports.c (scm_newptob): assign it.
1325 * strports.c (scm_mkstrport): set up the buffer.
1326 put just the string into the stream, not cons (pos stream).
1327 (stfill_buffer): new proc.
1329 * ports.h: fport buffer moved into port table: to be
1330 used for all port types.

1546 between strings is in capitalization.

1605 1999-03-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1607 * numbers.c (isfinite): Define this macro if not defined: Return a
1608 non-zero value if X is finite. (From ISO C 9x standard.)

1610 (Thanks to Jon Trowbridge and Greg Harvey.)
1612 1999-03-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1661 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1663 Most of this batch of changes is about how to deal with extended
1664 types when an object system is loaded into Guile. A nice object
1665 system is capable of representing Guile's types as class objects.
1667 For example, we want a regular expression to be of class <regex>.
1668 But regular expressions are smobs which aren't under direct
1669 control of the object system, so there has to be some mechanism
1670 which informs the object system that a new class should be created
1671 which can represent the smob type. I call this a "wrapper class".
1673 * objects.c: #include "smob.h";
1674 (scm_class_keyword): Removed. (Class is automatically created by
1676 (scm_smob_class): Array of smob classes indexed by smobnum.
1677 (scm_make_extended_class): "Plugin" function pointer for creation
1678 of wrapper classes for smob and struct types.
1679 (scm_class_of): Handle compiled closures. (Currently regarded as
1681 Use scm_smob_class to handle smob types;
1682 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1683 through scm_smob_class;
1686 * smob.c (scm_newsmob): Also create a wrapper class if
1687 scm_smob_class has been initialized.
1689 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1690 type code and smobnum.
1692 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1693 (scm_struct_table): Weak key table with auxilliary information for
1694 struct types. Currently used for names and wrapper classes.
1695 (scm_struct_ihashq): Hash function for structs.
1696 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1697 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1698 for accessing names of vtables. The record implementation in
1699 boot-9.scm currently uses the setter to record the name of record
1700 types. When the object system is initialized, it can use this
1701 information to create wrapper classes with suitable names.
1702 (scm_init_struct): Allocate scm_struct_table.
1703 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1704 (struct tags are a finite resource and we might want to restrict
1705 the use of tags to vtables only. E.g., Goops only uses tags for
1707 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1709 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1712 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1713 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1714 Used for access of struct table entries.
1716 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1717 (scm_hash_fold): New procedure. Used to process all entries in a
1718 hash table (in no particular order).
1720 Argh! For the umpteenth time I got compilation errors because of
1721 the "intuitive" name `kw'. This has to have an end:
1723 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1724 "kw" --> "keywords" everywhere.
1725 (I doubt that this will cause big compatibility problems since the
1726 application interface is unaffected.)
1728 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1730 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1732 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1733 column inums to native form.
1735 Improvement of backtraces: Introduces a new stack narrowing
1736 specifier, #t, for the inner cut. (See further in the comments in
1737 stacks.c:narrow_stack ().)
1739 * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
1740 (Used to flag certain system procedures which shouldn't turn up in
1743 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1744 modules which aren't "user" modules and the code of which
1745 shouldn't turn up in backtraces.)

1758 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
1760 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1762 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1763 procedure throughout.
1765 * print.c (scm_iprin1): Removed extraneous space when printing
1766 procedure-with-setters.
1768 Entity and operator setter slots were introduced as a complement
1769 to the <procedure-with-setter> type in order to support entities
1770 and operators with setters in a reasonable and efficient way.
1771 * procs.c (scm_procedure, scm_setter): Handle entity and operator
1774 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

1787 directly through the instance.
1789 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1791 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1792 scm_struct_i_flags instead of scm_vtable_index_layout!
1794 * list.c (scm_list_star): New procedure.
1796 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1877 SYMB now point to const.
1879 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1881 * print.c (scm_iprin1): Use scm_procedure_name instead of
1882 scm_procedure_property for compiled closures.
1884 * tags.h (scm_tc7_pws): New procedure type. Four representations
1885 for procedure-with-setters were considered before selecting this
1888 1. A closure where the CODE and ENV slots are used to represent
1889 the getter and a new SETTER slot is used for the setter. The
1890 original getter is stored as a `getter' procedure property. For
1891 closure getters, the CODE and ENV slots contains a copy of the
1892 getter's CODE and ENV slots. For subr getters, the CODE contains
1895 2. A compiled closure with a call to the getter in the cclo
1896 procedure. The getter and setter are stored in slots 1 and 2.
1898 3. An entity (i.e. a struct with an associated procedure) with a
1899 call to the getter in the entity procedure and the setter stored
1900 in slot 0. The original getter is stored in slot 1.
1902 4. A new primitive procedure type supported in the evaluator. The
1903 getter and setter are stored in a GETTER and SETTER slot. A call
1904 to this procedure type results in a retrieval of the getter and a
1905 jump back to the correct eval dispatcher.
1907 Representation 4 was selected because of efficiency and
1910 Rep 1 has the advantage that there is zero penalty for closure
1911 getters, but primitive getters will get considerable overhead
1912 because the procedure-with-getter will be a closure which calls
1915 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1916 <procedure-with-setter>, but together with rep 2 it suffers from a
1917 three level dispatch for non-GOOPS getters:
1919 cclo/struct --> dispatch proc --> getter
1921 This is because the dispatch procedure must take an extra initial
1922 argument (cclo for rep 2, struct for rep 3).
1924 Rep 4 has the single disadvantage that it uses up one tc7 type
1925 code, but the plan for uniform vectors will very likely free tc7
1926 codes, so this is probably no big problem. Also note that the
1927 GETTER and SETTER slots can live directly on the heap, using the
1928 new four-word cells.
1930 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,

2072 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
2073 SCM_STRUCTF_ENTITY): New constants.
2075 * struct.c (scm_make_struct): Allocate "invisible" room for
2076 procedures if SCM_STRUCTF_ENTITY is set in vtable.
2078 * gc.c (scm_gc_mark): Mark entity procedures.
2080 * struct.c, struct.h (scm_alloc_struct): Renamed from alloc_struct
2082 (scm_struct_init): Renamed from init_struct and made global.
2084 * objects.h (SCM_ENTITY, scm_entity): Removed.
2085 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
2086 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
2088 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
2090 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
2091 of syntactic forms, similar to SCM_PROC.
2092 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
2093 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
2094 for the name symbols when needed.
2096 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
2098 * Makefile.in: Regenerated.
2100 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
2102 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
2103 take the address of _into; it might be a register. Just have
2104 scm_debug_newcell return the new cell.
2105 * gc.c (scm_debug_newcell): Just return the new cell, instead of
2106 taking the address of a place to store it as an argument.
2107 * gc.h (scm_debug_newcell): Change declaration.
2108 (Thanks to Greg Harvey.)
2110 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2112 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
2113 Replaces old names serial-array-copy! and serial-array-map!.
2115 * evalext.c (map-in-order): New name. Replaces serial-map.
2117 1998-12-05 Jim Blandy <jimb@totoro.red-bean.com>
2119 * smob.c (freeprint): New function.
2120 (freecell): Use it to print freed objects, for slightly easier
2123 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2125 * backtrace.c (display_frame): Made more robust. Doesn't throw an
2126 error if no source properties can be found for a frame. (Thanks
2127 to Christian Lynbech.)
2129 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2131 * objects.h: Removed slots direct_supers and direct_slots from the
2132 definitions of the rudimentary classes described by objects.h.
2134 * objects.c, objects.h (scm_entity_p): New procedure. Together
2135 with the predicates scm_procedure_p and scm_struct_p, this
2136 predicate makes it possible to differ between structs, entities
2139 * modules.c, modules.h (scm_resolve_module): New function.
2141 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2143 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
2144 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
2147 * objects.c (scm_entity_p): New procedure.
2149 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
2150 for asubrs, rpsubrs, lsubrs and lsubr_2s.
2152 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2154 * procprop.h (scm_i_procedure_arity): Added declaration.
2156 * procprop.c (scm_i_procedure_arity): Made global; New code to
2157 handle operators and entities.
2158 (scm_procedure_property): No need to call scm_procedure_p since
2159 scm_i_procedure_arity now does all necessary type checking.
2160 Added #include "objects.h".
2162 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2163 s_add_hook_x --> s_remove_hook_x.
2164 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
2165 Added #include "procprop.h"
2167 * feature.c, feature.h (scm_reset_hook_x): New procedure.
2168 (scm_make_hook): Optional argument defines number of arguments to
2170 (scm_make_named_hook): Take number of args as second arg.
2171 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2172 boot-9.scm for a while); First arg is the hook. The rest are
2173 arguments passed on to the hook procedures.
2175 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
2177 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2178 scm_logbit_p): Do the computation in ulongs. This is not as nice
2179 as doing it in bignums, but at least it's good enough for
2180 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2182 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2183 subexpressions. (Thanks to Charbel Jacquin.)
2185 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
2187 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
2188 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2189 (scm_make_named_hook): New function.
2191 * feature.c: Added #include "eval.h".
2193 * modules.c (scm_make_module): Beautify the module.
2195 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2197 * modules.c, modules.h: New files: C interface to modules. (This
2198 is necessary in order to interface the object system to Guile
2199 properly. The guts of these modules will be replaced by the new
2200 module system in the future.)
2202 * init.c: Added #include "modules.h"
2203 (scm_boot_guile_1): Call scm_init_modules.
2204 (invoke_main_func): Call scm_post_boot_init_modules.
2206 * Makefile.am: Added modules.c, modules.x, modules.h.
2208 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
2210 * procs.c: #include "objects.h"
2211 (scm_procedure_p): Return #t also on structs which are operators.
2213 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
2214 <operator-metaclass> and <entity-class> to <standard-class>,
2215 <operator-class> and <entity> in order to conform with STKlos
2218 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
2219 which isn't an operator.
2220 (SCM_APPLY): Ditto, but jump to badproc.
2222 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
2224 * eval.c (SCM_CEVAL): Allow structs implanted in code.
2225 Previously, structs implanted in code were interpreted as forms
2226 the operator of which was a gloc. We solve this by checking for
2227 the zero in the emulated vcell in the struct vtable. Since
2228 implanted structs always will look like forms with a gloc
2229 operator, execution will only be slowed down by maximally one
2230 extra test-and-branch per application.
2232 * evalext.c (scm_definedp): Removed check for isyms; Added a
2233 second optional argument: It is now possible to supply an
2234 evaluation environment in which to look for the symbol.
2236 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2238 * readline.c (scm_init_readline): Set
2239 rl_basic_word_break_characters. (Thanks to Ian Grant.)
2241 * coop.c (coop_condition_variable_wait): Removed
2242 (coop_condition_variable_wait_mutex): Folded logic of
2243 coop_mutex_unlock into coop_condition_variable_wait_mutex to
2244 prevent condvar signal lossage. Previously, another thread could
2245 start to run after unlocking the mutex but before putting the
2246 current thread on the wait queue. If that thread then would
2247 signal the first, the signal would be lost. (Thanks to Christian
2250 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2252 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
2255 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2257 * objects.c (scm_i_make_class_object): Renamed from
2258 make_class_object; exported; error checking moved to
2259 scm_make_class_object and scm_make_subclass_object.
2260 (scm_make_class_object, scm_make_subclass_object): Use
2261 scm_i_make_class_object.
2262 (scm_make_subclass_object): Let the subclass have same metaclass
2265 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2267 * debug.c (scm_debug_options): Bugfix: Set the value of
2268 scm_stack_checking_enabled_p after setting debug options;
2269 #include "stackchk.h". (Thanks to Richard Polton.)
2271 1998-11-13 Radey Shouman <rshouman@metro2000.com>
2273 * unif.c (scm_array_contents): removed unnecessary test for 0
2276 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2278 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
2279 Replaced by macro `collect' in boot-9.scm.
2281 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2283 * eval.c (scm_copy_tree): Copy source properties if existent.
2285 * debug.c (scm_start_stack): Copy source when evaluating. (If we
2286 don't, we may end up passing memoized source to a transformer.)
2288 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2290 * stack.c (get_applybody): Help function which lookups the first
2291 body form of the apply closure.
2292 (read_frames): Prevent the source of the first form of the apply
2293 closure from being recorded. This would only be confusing.
2295 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
2296 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
2298 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
2300 * stacks.c (read_frame): Bugfix: Removed lingering `else'
2302 (read_frames): Use SCM_MACROEXPP.
2304 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2306 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
2307 don't contain interesting information since all arguments are
2308 present in the frame which applies the compiled closure anyway.);
2309 Skip the transformer application frames.
2311 * print.c (scm_iprin1): Print gsubrs as primitives.
2313 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2315 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
2317 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
2318 that we can identify these in a backtrace. (This change doesn't
2319 introduce any significant speed penalty.)
2321 * eval.c: Added note about `serial-map' using scm_map.
2323 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2324 readline options. They should reside in their own options array.
2326 * readline.c, readline.h (scm_readline_options,
2327 scm_readline_opts): Moved readline options here.
2329 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2331 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2332 SCM_ROCHARS instead of SCM_CHARS.
2334 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2335 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2337 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2339 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2340 This is quite important since the latter clears the
2341 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2342 every single character read...
2344 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2346 * print.c (scm_iprin1): Removed suspect looking (and indeed
2347 malevolent) semicolon after test for user supplied closure print
2348 procedure. (Thanks to Telford Tendys.)
2350 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2351 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2352 starting to search the list. Removed call to sloppy_mem_check.
2354 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2355 procedures: Same as scm_delq_x et al, but delete maximally one
2358 * options.c (scm_options, scm_init_options): GC-protect option
2359 values of type SCM. (Thanks to Telford Tendys.)
2361 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2363 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2364 make sure that there always is a "real" scm_lookupcar.
2366 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2368 * read.c, read.h (scm_read_opts): New read options
2369 "history-length" and "history-file".
2370 (scm_read_options): Stifle history to history length.
2372 * readline.c (scm_read_history, scm_write_history): New procedures.
2374 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2376 * eval.h (scm_macro_eval_x): Removed declaration.
2378 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2379 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2380 Renamed and made global.
2382 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2383 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2385 * evalext.c, evalext.h: New files. Contain non-R5RS things
2386 having to do with evaluation.
2388 * evalext.c (scm_serial_map): New procedure: Version of `map'
2389 which guarantees that the procedure is applied to the lists in
2391 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2392 returns a list of the results of the body forms instead of the
2393 result of the last body form.
2394 (scm_definedp, scm_m_undefine): Moved from eval.c
2396 * evalext.h (scm_m_sequence_to_list): Added declaration.
2398 * macros.c, macros.h: New files.
2399 (scm_procedure_to_syntax, scm_procedure_to_macro,
2400 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2401 scm_macro_name, scm_macro_transformer): Moved from eval.c
2402 (scm_make_synt): Moved from eval.c
2404 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2406 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2409 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2411 * debug.c, print.c: Added #include "macros.h".
2413 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2415 This change adds the ability to use `unread-char' multiple times
2416 without interspersed reads and adds the new procedure
2417 `unread-string'. The change is optimized for the common case of
2418 unreading a single character. This is also the reason behind the
2419 choice to store characters in the port itself: in most cases no
2420 extra malloc is required.
2422 The amount of code in some macros in ports.h has been increased to
2423 the extent that they would fit better as C functions, but, since
2424 this code belongs to the port representation, such functions
2425 should be placed in ports.c which would cause calls back and forth
2426 between ports.c and genio.c. That is not good for performance.
2427 Also, keeping them as macros allows the compiler to do some
2428 optimizations which are needed to make the current interface
2429 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2431 One benchmark (Guile startup time) indicates an increase of
2432 loading speed of 1%. Another (reading (using `read') boot-9.scm
2433 10 times) shows no change in performance.
2435 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2436 made to find a beautiful solution.)
2438 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2439 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2440 character. (SCM_CLRDY clears all.)
2441 (SCM_N_READY_CHARS): New macro: Returns number of unread
2442 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2443 (struct scm_port_table): New fields: `entry' contains port table
2444 index, `cp' points to last unread char, `cbuf' is the buffer for
2445 unread chars, `cbufend' points after end of the character buffer.
2447 * ports.h, ports.c (scm_unread_string): New procedure.
2448 (scm_grow_port_cbuf): New function.
2450 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2452 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2453 to read unread characters. Use SCM_TRY_CLRDY instead of
2456 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2458 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2460 * genio.c, genio.h (scm_ungets): New function.
2462 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2465 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2467 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2468 declarations. (Thanks to Russ McManus.)
2470 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2472 * numbers.c (num2long): As a software archeologist, I'm proud of
2473 this finding! :) Preliminary dating suggests an almost 4 year old
2474 remnant from the SCM ancestor. The sample has been removed from
2475 the finding site and is now safely stored in the repository.
2477 * numbers.h: Removed prototype for num2long.
2479 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2481 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2482 array as second arg.
2483 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2484 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2485 * gh.h: Updated and added prototypes.
2487 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2489 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2491 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2493 * guile-snarf.in: Never generate an empty file. (Thanks to
2496 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2497 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2498 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2499 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2500 gh_new_procedure5_0): Specify argument types, to appease C++
2501 compilers. (Thanks to Brad Bowman.)
2503 Bug reports from Russ McManus:
2504 * guile-snarf.in: If the CPP environment variable is set, use that
2505 as the C preprocessor, instead of the preprocessor autoconf
2507 * snarf.h (SCM_PROC): Cast the function pointer passed to
2508 scm_make_gsubr, to satisfy C++.
2510 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2511 Use the handler passed, instead of ignoring it and using
2512 gh_standard_handler. (Thanks to Etienne Bernard.)
2514 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2516 * ports.h: Put text after #endif in comment. (Thanks to Nicolas

2539 * script.c (scm_compile_shell_switches): Define
2540 use-emacs-interface in the root module, so the repl code can see
2541 it. See today's change to top-repl in ice-9/boot-9.scm.
2543 * filesys.c (set_element, get_element): Make sure that `element'
2544 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2545 Boekemeier and Jorgen "forcer" Schaefer.)
2547 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2549 * chars.c (scm_charnames): In ASCII character name table, make
2550 newlines print as #\newline by default, not #\nl.
2552 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2553 alphabetical order. Oh thrills. But it helps me know how far
2554 along in the compilation I am.
2555 * Makefile.in: Regenerated.

2559 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2560 #bytes(...) to #y(...), and syntax for short vectors from
2561 #short(...) to #h(...). This may seem nutty, but, like the other
2562 uniform vectors, byte vectors and short vectors want to have the
2563 same print and read syntax (and, more basic, want to have read
2564 syntax!). Changing the read syntax to use multiple characters
2565 after the hash sign breaks with the conventions used in R5RS and
2566 the conventions used for the other uniform vectors. It also
2567 introduces complexity in the current reader, both on the C and
2568 Scheme levels. (The Right solution is probably to change the
2569 syntax and prototypes for uniform vectors entirely.)
2571 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2573 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2574 (Thanks to Jorgen "forcer" Schaefer.)
2575 * ports.h (SCM_NOFTELL): New flag.
2576 * fports.c (local_fgets): If it's set, use the generic fgets.
2577 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2579 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2581 * script.c (scm_compile_shell_switches): Add handling of -q switch
2582 (inhibit loading of user init file).
2583 (scm_shell_usage): Add usage text for -q switch.
2584 (scm_compile_shell_switches): Always load user init file first if
2585 it is loaded at all.
2587 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2589 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2590 and is now broken under NetBSD. I can't fathom what it's trying
2591 to do, so I've replaced it with something that I do understand,
2592 which seems to work, and which isn't broken on NetBSD. "Progress?
2593 You Decide." (Thanks to Perry Metzger.)
2595 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2596 signed/unsigned comparison.
2598 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2600 Warning fixes from Greg Harvey:
2601 * unif.c (scm_array_set_x): initializer for pos
2602 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2603 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2604 initializers for field_type, since EGCS so desparately wants to
2606 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2607 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2608 when GUILE_DEBUG is defined.
2609 * dynwind.h (scm_wind_chain): Same.
2610 * ports.h (scm_pt_size, scm_pt_member): Same.
2611 * print.h (scm_current_pstate): Same.
2612 * procs.h (scm_make_cclo): Same.
2614 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2616 Handle short and long long uniform arrays properly. (Thanks to
2618 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2619 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2620 scm_tc7_llvect (long long vectors).
2622 Change the way libguile and boot-9.scm are timestamped, to try to
2623 get rid of these spurious mismatch warnings. Now both
2624 libguile/versiondat.h and ice-9/version.scm are generated directly
2625 by the configuration process, rather than having version.scm
2626 generated directly, and libguile/versiondat.h generated by the
2627 Makefile, which is generated by configure. It seems that
2628 sometimes the Makefile would change, but versiondat.h depends on
2629 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2630 * Makefile.am (versiondat.h): Target removed; this is generated
2631 directly by the configure script now.
2632 (BUILT_SOURCES): Remove versiondat.h.
2633 * versiondat.h.in: New file, transformed by the configure script
2635 * Makefile.in: Regenerated.
2637 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2638 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2639 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2640 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2641 if we want to use them in a header file some day, we can. (Thanks
2642 to Michael Livshin.)
2644 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2645 SCM numbers, so we won't have rollover problems; the range of a
2646 signed long in milliseconds is about 25 days. (Thanks to Karl
2649 Don't redefine sleep and usleep; fix this problem now.
2650 * coop.c (sleep, usleep): Remove declarations; we don't use or
2651 redefine these any more.
2652 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2653 job of usleep and sleep in a thread-friendly way. We can use
2654 these in the rest of Guile. Define versions for systems both with
2655 and without iselect.
2656 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2657 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2658 we're just using it, not redefining it, we can use a K&R style
2660 (sleep): Declare this, too, if the system hasn't.
2661 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2662 scm_uthread_sleep if they're available; otherwise, just call the
2664 * scmconfig.h.in: Regenerated.
2666 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2668 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2670 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2672 * threads.c: Doc fix.
2674 The argument type of usleep varies from system to system,
2675 as does the return type. We really shouldn't be redefining usleep
2676 at all, but I don't have time to clean that up before the 1.3.
2677 release. It's on the schedule for afterwards. (Thanks to Julian
2679 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2681 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2682 * scmconfig.h: Regenerated.
2684 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2685 right way to handle system variation. Autoconf's approach is the
2687 * simpos.h (scm_software_type): Declaration deleted.
2689 * script.c (scm_find_executable): Don't test if unix is #defined
2690 here; first, NetBSD doesn't #define it, and second, it's the wrong
2691 way to go about these things. (Thanks to Perry Metzger.)
2692 (dld_find_executable): Delete this MSDOS support code. This isn't
2693 the way we want to support this; it needs to be rethunk at a
2696 * genio.c (scm_do_read_line): Don't just politely check that the
2697 line was either non-empty or EOF. Abort if it's empty and not
2700 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2702 * scmconfig.h.in: Regenerated.
2704 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2707 * genio.c (scm_do_read_line): Count lines correctly when the file
2708 doesn't end in a newline.
2710 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2712 * genio.c (scm_do_read_line): Maintain the line count correctly.
2713 (Thanks to Harvey J. Stein and Greg Harvey.)
2715 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2718 * numbers.c (big2str): Protect t from garbage collection until
2719 we're done. (Thanks to Gary Houston.)
2721 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2723 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2725 * Makefile.in: Regenerated.
2727 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2728 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2731 Do magic to mix reads and writes on stdio FILE-based ports.
2732 (Thanks to Christian Lynbech.)
2733 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2735 (pre_read, pre_write): New functions.
2736 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2737 local_fputs): Call them.
2738 (local_fflush): Mark the port as ready for reading and writing.
2739 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2740 flags on new port objects. This might not be accurate --- who
2741 knows what state the FILE * is in when we get it --- but it won't
2742 do extraneous calls to fflush or fseek, so it's no worse than the
2743 behavior before this change.
2744 * ports.h: Add comment.
2746 Centralize the creation of port objects based on stdio FILE * in
2747 fports.c; don't just throw them together anywhere.
2748 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2749 what the rest of Guile wants. Don't set the revealed count;
2750 that's only appropriate for stdin, stdout, stderr.
2751 (scm_standard_stream_to_port): This function does set the revealed
2753 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2754 not scm_stdio_to_port.
2755 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2756 * fports.c (scm_open_file): Same.
2757 * posix.c (scm_pipe): Same.
2758 * socket.c (scm_sock_fd_to_port): Same.
2759 * ioext.c (scm_fdopen): Same.
2760 (scm_freopen): Moved from here to...
2761 * fports.c (scm_freopen): ... here. This is really something that
2762 munges the internals of an fport, so it should go here.
2763 * fports.h (scm_stdio_to_port): Adjust prototype.
2764 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2765 * ioext.h (scm_freopen): Prototype removed.
2767 * filesys.c (set_element, get_element): This can work on both pipe
2768 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2771 * scmconfig.h.in: Regenerated.
2773 Change the definition of the functions in scm_ptobfuns so that
2774 they get passed the port object, not the port's stream.
2775 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2776 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2777 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2778 Pass the port itself to the scm_ptobs function.
2779 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2780 scm_generic_fgets): Same.
2781 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2782 getc_void_port, fgets_void_port, close_void_port): Just change the
2783 argument names; these functions don't really do anything.
2784 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2785 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2786 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2787 Also, use prototyped definitions, and get rid of the extra
2789 (scm_fptob, scm_pipob): We don't need casts here any more.
2790 * strports.c (prinstpt): Use prototype declarations.
2791 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2792 and use SCM_STREAM to get the string info. Also, use prototyped
2793 definitions, and get rid of the extra declarations.
2794 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2797 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2798 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2800 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2801 scm_fgets, for consistency.
2802 (scm_fptop, scm_pipob): References updated.
2804 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2806 Include the source location in error messages for scripts.
2807 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2808 stack is still there when we catch the error.
2809 * throw.c (handler_message): If we are handling an error with a
2810 message, then put together the proper arguments and call
2811 scm_display_error, instead of scm_display_error_message. That
2812 displays source location, if it can find it.
2814 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2816 * gc.c (scm_unprotect_object): Change this so that calls to
2817 scm_protect_object and scm_unprotect_object nest properly.
2818 (scm_protect_object): Doc fixes.
2820 * strings.c (scm_string_set_x): Require the argument to be a
2821 writable string, not a substring or a symbol.
2822 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2823 (Thanks to John Redford and Charbel Jacquin.)
2825 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2827 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2829 * eval.c (safe_setjmp): Remove this misunderstanding.
2830 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2833 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2835 * libguile.h: Mark these as C declarations, for compilation by C++
2838 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2839 __cplusplus clause. I seriously doubt this ever worked the way
2840 the author seems to have intended.
2842 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2844 Utterly needless cleanups to hopelessly messy code.
2845 * ports.c: Doc fixes.
2846 (scm_fflush): Moved to ...
2847 * genio.c (scm_fflush): ... here, amongst all the other port
2848 method invocation functions.
2849 * genio.h, ports.h: The prototype moves too.
2851 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2853 * backtrace.c (display_error_body): The current frame does not
2854 always have a parent frame; consider a function called directly
2855 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2858 * alloca.c (alloca): Undo yesterday's changes, and simply call
2859 malloc directly for storage, and abort if we don't get what we
2860 want. The situation is much simpler --- just call malloc. Emacs
2861 has bizarre/evil requirements (signal handlers might malloc unless
2862 you set this global flag, so you have to set the flag around all
2863 calls to malloc) which we are certainly not going to conform to,
2864 so we can do the simple and obvious thing.
2866 * coop.c (coop_condition_variable_wait): Make this function
2867 static. It's only useful internally --- you should never just
2868 wait on a condition variable.
2869 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2871 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2873 * unif.c (scm_array_set_x): Accept any kind of number as an
2874 element for a uniform vector of doubles. This is more consistent
2875 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2877 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2878 works; I can't conveniently test it myself. (Thanks to Dvid
2879 Tillman for the bug report.)
2881 * init.c: Doc fixes.
2883 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2884 from here, not from scm_compile_shell_switches (which is a pretty
2885 dumb place to do it).
2886 (scm_load_startup_files): New function.
2887 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2888 * script.c (scm_compile_shell_switches): Don't load the startup
2890 (scm_ice_9_already_loaded): Variable moved.
2891 * init.c (scm_load_startup_files): Prototype for new function.
2892 * gh_init.c (gh_enter): Doc fix.
2894 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2896 Some anti-warning changes from Greg Harvey.
2897 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2898 warnings when it doesn't understand our NORETURN declarations in
2900 * posix.c (scm_mknod): Similar.
2902 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2904 * posix.c (scm_getpwuid): If we can't find an entry, return our
2905 own message, instead of using scm_syserror --- the getpwMUMBLE
2906 functions don't set `errno' to anything interesting.
2908 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2910 Get rid of warnings from the cooperative threading system.
2911 * threads.h (scm_single_thread_p, scm_yield,
2912 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2913 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2914 scm_wait_condition_variable, scm_signal_condition_variable): Add
2915 prototypes for these Scheme-visible functions.
2916 * coop-defs.h (coop_next_runnable_thread,
2917 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2918 Prototypes for these here, even though they're from iselect.c.
2919 (coop_condition_variable_wait, coop_join): Add prototypes.
2920 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2921 scm_threads_free_condvar): Make these smob functions static.
2922 * coop-threads.h (coop_init): Give this a real prototype.
2923 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2924 (coop_next_runnable_thread): No need to provide prototype; it's in
2927 * scmconfig.h.in: .detarenegeR
2929 * iselect.c, threads.c: Doc fixes.
2931 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2933 * Makefile.in: Regenerated with a patched automake, to get
2934 dependency generation right when using EGCS.
2936 * inet_aton.c (inet_aton): Add prototype, to remove compiler
2937 warning. (Thanks to Robert Pluim.)
2939 * inet_aton.c (inet_aton): Reassure the compiler that the
2940 arguments to the <ctype.h> macros are all unsigned characters, not
2943 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2945 Getting rid of more warnings...
2946 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
2947 today's change to ../configure.in.
2948 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
2949 * scmconfig.h.in: Regenertaded.de.,.__
2950 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
2951 (scm_localtime, scm_mktime): Use a const char * to manipulate the
2954 * readline.c: Doc fix.
2955 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
2956 * readline.h (scm_filename_completion_function): Add prototype.
2957 (scm_init_readline): Make this into a prototype.
2959 * readline.c (scm_filename_completion_function): Use SCM_PROC to
2960 declare this, instead of calling scm_make_subr manually.
2962 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
2964 * readline.h (scm_init_readline): Add prototype for this.
2965 (scm_init_readline): Make this a real prototype.
2967 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
2969 Warning fixes from Maciej Stachowiak:
2970 * backtrace.h (scm_display_application, scm_backtrace): Add
2972 * debug.c (scm_m_start_stack): Make this function static.
2973 * fluids.h (scm_fluid_p): Add prototype.
2974 * procprop.c (scm_i_procedure_arity): Make this function static.
2975 * regex-posix.c (scm_regexp_error_msg): Make this function static.
2976 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
2977 * root.h (scm_dynamic_root): Add external prototype.
2978 * scmsigs.h (scm_usleep): Add external prototype.
2979 * script.h (scm_init_script): Use prototype, not K&R decl.
2980 * stacks.h (scm_stack_id): Add external prototype.
2981 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
2983 1998-09-30 Mark Galassi <rosalia@cygnus.com>
2985 * gh.h: took out the definitions of vset and vref, since they are
2986 replaced by the proper vector routines that correspond to the R4RS
2989 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
2991 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
2992 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
2993 third argument, a C expression that should result in a SCM value,
2994 which is used to initialize the variable. Reimplemented
2995 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
2998 * version.h (scm_libguile_config_stamp): Add prototype.
2999 (From Maciej Stachowiak.)
3001 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
3003 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
3004 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
3006 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
3008 * print.c (scm_iprin1): Rather than having one i, and using it in
3009 several places, declare a fresh i local to each block where it is
3010 used, and give it a signedness appropriate to its use in each case.
3011 (scm_iprlist): Same.
3013 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
3014 comparison warnings.
3016 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
3017 signed/unsigned clashes.
3019 * posix.h (scm_tmpnam): Added prototype.
3021 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
3022 scm_make_subclass_object): Add external prototypes.
3024 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
3025 comparison is okay here.
3027 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3029 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3030 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3032 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3035 * load.c (swap_port): Make this function static.
3037 * load.c (scm_search_path): Make max_path_len and max_ext_len
3038 unsigned, since they're compared against string sizes.
3040 * load.c (init_build_info): Make i unsigned.
3042 * ioext.h (scm_read_line): Add prototype.
3044 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3045 scm_hash_fn_remove_x): Make hash bucket index local variable k
3046 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3047 accurately as possible.
3049 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3050 comparisons, and range checking to make sure those casts are
3053 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3054 signed/unsigned comparisons.
3056 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3057 avoid signed/unsigned comparisons.
3058 * smob.h (scm_numsmob): Change extern declaration to match.
3060 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3061 avoid signed/unsigned comparisons.
3062 * ports.h (scm_numptob): Change extern declaration to match.
3063 (scm_current_load_port, scm_set_port_line_x,
3064 scm_set_port_column_x): New prototypes.
3066 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3067 test code, and it causes warnings.
3069 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3070 gh_uniform_vector_ref): Added prototypes.
3072 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3073 debugging support unconditionally. That's backtrace.c, stack.c,
3074 debug.c, and srcprop.c.
3075 (EXTRA_libguile_la_SOURCES): Omit those from here.
3076 * Makefile.in: Regenerated.
3078 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3080 * options.c (scm_options): Bugfix: Allow empty list of options!
3082 * debug.c, debug.h (scm_single_step): Removed.
3083 (scm_with_traps): New procedure. This procedure could easily be
3084 written in Scheme but needs to be highly optimized.
3086 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3088 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3089 Check SCM_TRAPS_P before trapping.
3091 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3093 Changes to avoid signed/unsigned comparison warnings.
3094 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3095 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3096 so they can have appropriate types for each application. Make i
3097 signed. Use initializers in some spots. I'll probably pay for
3099 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3100 (scm_must_realloc): Make nm unsigned.
3101 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3102 (scm_init_storage): Use prototype-style definition, and make the
3104 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3105 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3107 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3108 avoid signed/unsigned comparison warnings, and because the return
3109 value of readlink may be -1. Don't bother casting the third
3110 argument to readlink.
3112 * filesys.c (scm_dirname, scm_basename): Move these to their own
3113 page, at the end of the file.
3114 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3116 * eval.h (scm_eval_options_interface): Add external prototype for this.
3117 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3119 * eval.c (scm_lookupcar1): Make this static.
3121 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3122 Make these prototype declarations, not K&R-style.
3124 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3125 unsigned comparison warning.
3127 * appinit.c: File removed. It had a single function in it, empty,
3128 whose reason for existence is explained in no documentation or
3129 comment. I think it's there as a default for some Tcl-style
3130 initialization, but Tcl abandoned that approach a while ago.
3131 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3132 (BUILT_SOURCES): Remove appinit.x.
3133 * Makefile.in: Regenerated.
3135 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3137 * Makefile.in: Regenerated using the last public version of
3138 automake, not the hacked Cygnus version.
3140 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3142 Remove Totoro kludge.
3143 * Makefile.in, scmconfig.h.in: Regenerated.
3144 * init.c, readline.c: Don't check if TOTORO is #defined.
3146 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3148 * Makefile.am: Adjust for new thread configuration system.
3149 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3150 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3152 (THREAD_LIBS): Definition deleted; automake will generate such
3153 things automatically.
3154 * Makefile.in: Regenerated.
3156 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3158 Simplify smob and port marking; set the mark bit in the generic
3159 marking code, and make marker routines only responsible for
3160 turning up outgoing pointers.
3161 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3162 before calling the marking function. Don't call the marking
3163 function if it's zero.
3164 * markers.c (scm_mark0): Just return #f. This function isn't
3165 necessary at all now, but it's harmless to call it. We'll leave
3166 it in so other folks' code doesn't croak at link time.
3167 (scm_markcdr): Don't call SCM_SETGC8MARK.
3168 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3169 * dynl.c (mark_dynl_obj): Same.
3170 * root.c (mark_root): Same.
3171 * srcprop.c (marksrcprops): Same.
3172 * unif.c (markra): Same.
3173 * variable.c (scm_markvar): Same.
3174 * ports.c (scm_markstream): Same.
3175 (void_port_ptob): Specify zero for our marking function.
3176 * debug.c (debugobjsmob): Same.
3177 * dynwind.c (guardsmob): Same.
3178 * filesys.c (dir_smob): Same.
3179 * fluids.c (fluid_smob): Same.
3180 * fports.c (scm_fptob, scm_pipob): Same.
3181 * mallocs.c (mallocsmob): Same.
3182 * regex-posix.c (regex_t_smob): Same.
3183 * smob.c (freecell, flob, bigob): Same.
3184 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3185 * throw.c (jbsmob, lazy_catch_funs): Same.
3187 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3189 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3190 scm_copy_tree on code in order not to let memoized code to leak
3191 out. Thus, scm_copy_tree needs to copy vectors as well since
3192 quasiquote can introduce evaluated code also inside vector
3195 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3197 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3199 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3200 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3203 * unif.c: Say that ivect and uvect are of type signed and unsigned
3204 long instead of int in commentary so that it correctly describes
3207 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3209 * stime.c: Removed declaration of strptime. (It should be
3210 declared by the system headers. If it turns out that some systems
3211 don't, we'll handle that then.) (Thanks to Greg Troxel.)
3213 * stime.h: Renamed TIMEH --> STIMEH
3215 * backtrace.c (scm_display_error, scm_display_backtrace): In order
3216 to increase portability, don't use structure assignment.
3217 (Thanks to Nicolas Neuss.)
3219 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
3221 (finalize_fd_sets): Added empty statement after last case label.
3222 (Thanks to Nicolas Neuss.)
3224 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
3227 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
3229 * init.c, readline.c: OK, I won't have these readline.x bug
3230 reports anymore. We've had them since April. The current reason
3231 is a completely unintelligible failure of totoro.red-bean.com to
3232 do the test for rl_getc_function in libreadline correctly. This
3233 kludge overrides the test if we're on totoro so that the snapshot
3234 generation process can work.
3236 * readline.c: Define a strdup replacement if not existent on system.
3238 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3240 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
3241 This change makes scm_make_vector R5RS compatible. We cannot keep
3242 the third argument since people want to be able to deduce the form
3243 of the C function call only by looking at R5RS. (At the same time
3244 we have removed some unnecessary complexity!)
3246 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
3247 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
3248 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
3249 argument in call to scm_make_vector.
3251 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3253 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
3254 This macro is useful in applications.
3256 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3258 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
3259 (scm_parse_path, scm_search_path): New Scheme level procedures.
3261 * load.h (scm_internal_parse_path, scm_parse_path,
3262 scm_search_path): Declared.
3264 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3266 * filesys.c (dirname, basename): New procedures.
3268 * init.c (scm_boot_guile_1): Removed condition around
3271 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
3272 new data type (guards) for representation of C level guards and
3273 data on the wind chain.
3274 (scm_internal_dynamic_wind): New function.
3276 * dynwind.h: Declare scm_internal_dynamic_wind.
3278 * root.h (scm_root_state): Added scm_cur_loadp.
3280 * root.c (mark_root): Added comment about cur_loadp.
3282 * load.c: #include "dynwind.h";
3283 (scm_primitive_load): Use scm_inner_dynamic_wind to update
3286 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
3288 * ports.c (current-load-port): New procedure.
3290 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3292 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
3293 not a tty, return #f.
3295 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
3296 to Julian Satchell and Roland Kaufmann.)
3298 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
3299 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
3301 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3303 * debug.h, debug.c (scm_start_stack): New function. Implements
3304 the guts of old scm_m_start_stack.
3306 * debug.c (scm_m_start_stack): Use scm_start_stack.
3308 * init.c (scm_start_stack, scm_restart_stack): Renamed to
3309 start_stack and restart_stack. (These have static scope.)
3311 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3313 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
3314 readline functions to come in release 2.3. (Thanks to Chet
3316 (handle_errors): Use the above functions.
3318 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3320 * readline.c: Improvements for readline support: Handle errors
3321 better; Implement before-read-hook.
3323 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3325 * init.c (scm_boot_guile_1), readline.c: Test for
3326 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3327 assure that we have version >= 2.1.)
3329 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3331 * readline.c (scm_readline): Defer interrupts while we're calling
3334 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3335 away the string to add_history.
3336 (completion_function): Do completion for readline. (Thanks to
3338 (scm_filename_completion_function): New procedure: Filename
3340 (current_input_getc): New function. Use this one instead of
3341 standard getc from readline.
3343 * throw.c, throw.h (scm_handle_by_throw): New function: This
3344 handler throws errors to next handler on the dynwind chain.
3346 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3348 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3351 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3353 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3355 (scm_procedure_properties): Modified to return arity together with
3357 (scm_procedure_property): Added the read-only property `arity'.
3358 (scm_set_procedure_property_x): It is an error to set the `arity'
3361 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3362 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3364 * procprop.h (scm_sym_arity): New symbol.
3366 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3367 to set the dispatch procedure of an operator or entity object.
3369 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3370 Made procedure slots read-only.
3372 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3373 scm_tcs_cons_gloc case in zero args switch; Fixed args
3374 construction for operators in scm_tcs_cons_gloc case in two args
3377 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3379 * fluids.c: Removed use of assert.h (in order to avoid
3382 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3384 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3386 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3387 change makes the evaluator safer at the cost of evaluation speed.
3388 It handles the case when the user has added a non-immediate
3389 improper end of the application form, e.g., `(+ 0 . x)'.
3390 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3391 minimize the extra cost as much as possible. The new code is
3392 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3393 problem with structs planted directly in the code (e.g. by a
3394 macro). This no longer causes segmentation fault. (Thanks to
3397 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3398 arg `proc' in order to be able to throw errors; New argument
3401 * Removed extra #include "debug.h"
3403 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3405 * scmsigs.c: Declare usleep as returning void on some systems.
3406 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3409 * coop.c (usleep): Return void on some systems.
3411 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3413 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3415 * coop.c: Changed return type of usleep to int.
3417 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3418 isn't found in the OS.
3420 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3421 isn't enabled. (Thought that I had made this change ages ago...)
3423 * iselect.c: Declare bzero if not defined by OS.
3425 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3427 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3428 condition. (Thanks to John Tobey.)
3430 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3431 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3434 * __scm.h: Start the long-term project of moving to POSIX threads.
3435 Phase 1: Classification of all critical sections.
3436 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3437 for A sections. (See comments in __scm.h for details.)
3439 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3440 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3442 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3444 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3445 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3446 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3447 dependencies on $(srcdir)/Makefile.in
3448 $(top_builddir)/config.status in order to avoid circularity.
3450 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3451 from argc if argc was 0 initially.
3453 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3454 in generation of libpath.h.
3456 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3458 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3459 libguile from 2 to 3.
3461 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3463 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3465 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3467 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3468 scm_set_port_column_x, scm_port_filename,
3469 scm_set_port_filename_x): Removed optional arguments. Added
3470 proper argument checking.
3472 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3473 stack size in machine words.
3475 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3476 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3477 to Ole Myren Röhne.)
3479 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3481 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3482 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3484 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3487 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3488 procedure apply: Copy argument lists before pushing them unto the
3489 environment so that the environment won't get mutated due to
3490 manipulation of procedure arguments. This should perhaps be
3491 regarded as a temporary solution until someone finds a more
3492 efficient one. (Thanks to Maciej Stachowiak.)
3494 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3496 * script.c (scm_compile_shell_switches): Use "guile" as default
3497 zero arg if argc is NULL.
3499 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3501 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3502 is zero. (Thanks to Dirk Herrmann.)
3504 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3506 * ports.c (scm_add_to_port_table): First line is now line 0
3507 (was 1). (Interface changed according to suggestion by Per
3510 * backtrace.c (display_header): Add 1 to line and column numbers
3511 when presenting them to the user.
3513 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3514 from debug.c --> eval.c
3516 * eval.h, eval.c (scm_eval_options_interface): New options
3518 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3519 i.e. stacks for new threads.
3521 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3523 * eval.c (unsafe_setjmp): Removed with #if 0.
3525 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3528 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3529 to avoid compiler warnings.
3531 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3533 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3535 * throw.c (handler_message): Print message on current error port
3536 instead of default error port. (Thanks to Maciej Stachowiak.)
3538 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3540 * ports.c (scm_add_to_port_table): allocate in units of
3541 struct scm_port_table *, not struct scm_port_table.
3542 * posix.c (scm_close_pipe): remove the port from the port table
3544 Thanks to Rob Engle for both fixes.
3546 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3548 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3549 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3551 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3553 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3555 * backtrace.c (display_error_body, display_backtrace_body),
3556 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3557 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3558 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3559 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3562 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3563 don't receive the jmpbuf arg anylonger.
3564 (scm_catch): Don't accept a #f tag.
3565 (scm_throw): Check that key is a symbol.
3566 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3568 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3570 * async.c (async_pending): Removed declaration.
3572 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3574 * dynwind.c (scm_wind_chain): New debug function.
3576 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3577 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3578 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3579 extra layer of functions around the body and handler of a thread.
3580 This extra layer makes sure that the handler is called in the
3581 dynamic context of the surround (= empty dynwind list), but under
3582 the *dynamic root* of the body. We can not use the dynamic root
3583 of the surround since that root belongs to another thread => stack
3584 is not handled correctly. It may seem ugly to use this extra
3585 layer, but the extra cost in terms of execution time is really
3586 negligible compared to the total amount of time required to create
3587 a thread, and it would reduce maintainability to duplicate the
3588 crucial and complicated steps performed by cwdr.
3590 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3591 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3592 get re-enabled. The important effect of this is that interrupts
3593 are blocked during thread switching so that thread data structures
3594 don't risk getting messed up by an unfortunate signal.
3595 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3596 seems to do more aggressive optimization which actually move
3597 instructions around in these macros in a fatal way. Therefore:
3598 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3599 just superstitious...)
3600 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3601 This macro should be used instead of SCM_ASYNC_TICK since the
3602 latter doesn't do context switches any more.
3604 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3605 instead of SCM_ASYNC_TICK.
3607 * coop.c, iselect.c: Since thread switches are now performed with
3608 interrupts masked, we can't use the old mechanism of delivering
3609 signals immediately when they arrive. Signals must instead be
3610 delivered when the asyncs run *after* the end of the critical
3611 section in scm_internal_select. But this also means after context
3612 switch so that the signal will be delivered to a different thread.
3613 To avoid this, I have changed the protocol of
3614 coop_wait_for_runnable_thread and friends so that they are allowed
3615 to return the original thread. So, if a signal arrives during
3616 scm_internal_select, we won't any longer be forced do a context
3617 switch, but can remain in the same thread and deliver the signal
3620 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3621 scm_asyncs_pending and made it global.
3623 * iselect.c: Small fixes.
3625 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3626 coop_condition_variable_init, coop_condition_variable_wait,
3627 coop_condition_variable_signal): Changed return type from `void'
3628 to `int'. This is to adhere closer to the pthreads interface.
3629 This, in turn, is part of an attempt to provide C versions of the
3630 mutex and condition variable primitives which can be part of a
3631 frontend to COOP or pthreads.
3633 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3634 coop_condition_variable_destroy): New functions.
3636 * coop-threads.c (scm_wait_condition_variable): Use
3637 coop_condition_variable_wait_mutex.
3639 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3640 Definitions moved to coop-defs.h.
3642 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3643 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3644 scm_cond_destroy): New C interface to mutecis and cond vars.
3646 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3648 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3650 * iselect.c: Now several threads can wait on the same file
3651 descriptor. The behaviour is compatible with OS select: All
3652 threads waiting for the fd return with the same status.
3654 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3656 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3657 Can spawn a thread from application C code.
3659 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3661 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3662 gh_doubles2scm): New functions.
3664 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3666 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3667 commented-out version of gh_eval_str()
3669 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3671 * socket.c (scm_bind): free soka after use.
3673 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3675 * stime.c (tzvar): new variable.
3676 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3677 avoid memory leaks when allocating.
3679 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3681 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3684 * gc.c, tags.h: Doc fixes.
3686 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3688 * eval.c (macro-eval!): Removed. This function was a design bug.
3689 It allowed memoized code to leak out to the scheme level. Most
3690 things that you could do with `macro-eval!' can be done with
3693 1997-12-20 Tim Pierce <twp@skepsis.com>
3695 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3696 scm_fgets now depends on ftell(3) to know how many bytes were
3699 1997-12-15 Tim Pierce <twp@skepsis.com>
3701 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3702 dealing with strings.
3704 1997-12-13 Tim Pierce <twp@skepsis.com>
3706 Make %read-line more suitable for implementing read-line efficiently.
3707 * ioext.c (scm_read_line): Strip the terminating newline from a
3708 string, and return a cons of the string and its terminator.
3710 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3711 of the string that is read is stored in this memory location.
3712 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3713 * genio.c, genio.h (scm_do_read_line): Update caller.
3714 * ports.h (scm_ptobfuns): Update typedef.
3715 * fports.c (scm_fptob, scm_pipob): Update struct.
3717 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3719 * filesys.c (set_element): Return file descriptor.
3720 (fill_select_type): Return the highest file descriptor.
3721 (scm_select): Tell select about the highest file descriptor. On
3722 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3723 Therefore the extra overhead for calculating the maximum fd seems
3724 to be more than compensated. Is this correct? In any case,
3725 scm_internal_select will be much faster with this info.
3726 (scm_select, fill_select_type, set_element): Don't accept any kind
3727 of object in the file descriptor list or vector.
3729 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3731 * iselect.c (finalize_fd_sets): Bugfix.
3733 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3735 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3736 when using scm_internal_select (since we might switch to another
3739 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3741 * simpos.c (scm_system): always define: use sysmissing if not
3742 available. Check for HAVE_SYSTEM instead of _Windows (does
3743 Windows lack system or does it have an unusable one?).
3744 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3745 Let the argument be optional: if not supplied, call system(NULL).
3747 * ports.c (scm_close_port): relax the type check from OPPORTP to
3748 PORTP; closing a closed port is allowed.
3750 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3752 * fports.c (scm_fgets): Return if the last char in a chunk is
3753 newline. When fgets returns a string whose length is `size-1', it
3754 is ambiguous whether a whole line was retrieved, so we must check
3755 explicitly whether a line terminator is present.
3757 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3759 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3760 before taking the CDR. (Thanks to Harald Meland.)
3762 * filesys.c (scm_stat): Slightly optimized.
3764 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3766 * ports.c (scm_close_port): Make sure the port is open before
3769 * guile-snarf.in: Pass args through to gcc in a way that preserves
3770 whitespace boundaries. (Thanks to Greg Badros.)
3772 1997-12-02 Tim Pierce <twp@skepsis.com>
3774 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3775 statement. (Thanks to Doug Evans for pointing this out.)
3777 1997-12-01 Tim Pierce <twp@skepsis.com>
3779 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3781 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3783 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3784 errno macro expansion of this field name. (errno is a C
3785 preprocessor macro on some systems.)
3787 1997-11-29 Tim Pierce <twp@skepsis.com>
3789 * iselect.c: Doc fix.
3791 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3793 * init.c (scm_start_stack): Removed initialization of
3794 scm_the_last_stack_var.
3796 * backtrace.h: Declare scm_the_last_stack_var.
3798 * backtrace.c: Define scm_the_last_stack_var.
3800 * root.c (mark_root): Don't mark the_last_stack_var.
3802 * root.h (scm_root_state): Removed the_last_stack_var.
3804 * throw.c: Added #include "fluids.h"
3805 (ss_handler): `the-last-stack' is now a fluid.
3807 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3808 --> the_last_stack_fluid.
3810 * backtrace.c: Added #include "fluids.h"
3811 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3812 (scm_backtrace): `the-last-stack' is now a fluid.
3814 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3815 after scm_init_fluids.
3817 1997-11-28 Tim Pierce <twp@skepsis.com>
3819 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3821 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3822 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3824 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3826 * iselect.c (coop_next_runnable_thread,
3827 coop_wait_for_runnable_thread): Disable interrupts so that no
3828 async is executed before a potential error_revive.
3829 (scm_internal_select): Disable interrupts during the parts of the
3830 code which manipulate the sleep queue and the file descriptors.
3832 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3834 * Makefile.am: Added iselect.c and iselect.h.
3836 * coop.c (coop_qinit): Initialize fields used by
3837 scm_internal_select.
3838 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3839 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3840 replacement in iselect.c.
3841 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3842 coop_join): If GUILE_ISELECT enabled, use
3843 coop_wait_for_runnable_thread instead of
3844 coop_next_runnable_thread.
3845 (usleep, sleep): New replacements for system functions if
3846 GUILE_ISELECT is enabled.
3848 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3850 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3852 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3853 iselect.h. Implement Scheme level `select' using
3854 scm_internal_select. (See NEWS.)
3856 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3858 * init.c: Call scm_init_iselect.
3860 * iselect.h, iselect.c: New files. Implements
3861 scm_internal_select. (See NEWS.)
3863 1997-11-27 Tim Pierce <twp@skepsis.com>
3865 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3866 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3867 and scm_must_free, since ultimately the string returned will be copied
3868 by scm_makfrom0str anyway. Also, read any characters that may have
3869 been pushed onto the port with scm_ungetc.
3870 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3871 * ioext.c (scm_read_line): Free string after Guilifying it.
3872 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
3874 1997-11-26 Anthony Green <green@hoser.cygnus.com>
3876 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
3878 * gh.h: Safely wrap prototypes for c++ usage.
3880 1997-11-25 Mark Galassi <rosalia@cygnus.com>
3882 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3883 gh_repl (argc, argv).
3885 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3887 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3888 and to invoke scm_shell().
3889 (gh_launch_pad): took out the loading of boot-9.scm from here,
3890 since it is probably best to let the user control that. In fact,
3891 gh_repl() now invokes scm_shell() which does that.
3893 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3895 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3898 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
3900 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
3901 yesterday's underscore patch. (Thanks to Marius Vollmer for
3904 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
3906 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
3907 DLSYM_ADDS_USCORE is not defined.
3909 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
3911 * gh_data.c (gh_uniform_vector_length):
3912 (gh_uniform_vector_ref): started implementing the uniform types in
3915 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
3917 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3918 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3920 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3922 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
3923 configure.in was changed).
3925 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
3927 * Makefile.am (modinclude_HEADERS): Include readline.h here.
3928 * Makefile.in: Regenerated.
3930 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
3932 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
3933 OPORT is an `open' port, not an output port.
3935 * filesys.c (scm_close, set_element, get_element, scm_chown,
3936 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
3937 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
3938 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
3939 scm_close_port, scm_port_line, scm_set_port_line_x,
3940 scm_port_column, scm_set_port_column_x, scm_port_filename,
3941 scm_set_port_filename_x, scm_port_mode,
3942 scm_close_all_ports_except, scm_set_current_output_port,
3943 scm_set_current_error_port): Likewise
3944 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
3945 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
3947 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
3948 * backtrace.c (display_backtrace_body): Likewise
3949 * fports (scm_setvbuf): Likewise
3950 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
3951 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
3952 scm_getpeername, scm_send, scm_sendto): Likewise
3953 * unif.c (scm_uniform_array_write): Likewise
3955 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
3957 Minor problems with substring-related tag changes.
3958 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
3959 exactly what we want to leave in to detect substrings.
3960 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
3961 * tags.h: Fix diagrams and comments describing the S tag bit;
3962 remove vestigial remarks about the D tag bit.
3963 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
3964 * strings.c: Formatting tweaks.
3966 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
3967 variable first; then SCHEME_LOAD_PATH, with a warning message.
3968 (scm_parse_path): New function.
3969 * script.c: Doc fixes.
3971 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
3973 Readline support, from Daniel Risacher.
3974 * readline.c, readline.h: New files.
3975 * init.c: #include "readline.h".
3976 (scm_boot_guile_1): Call scm_init_readline, if we have it.
3977 * Makefile.am (libguile_la_SOURCES): Include readline.c.
3978 * Makefile.in: Regenerated.
3979 * scmconfig.h.in: Regenerated, after change to ../configure.
3981 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3983 * gh.h: gh_vector_set -> gh_vector_set_x
3985 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3987 * gh_data.c (gh_vector_set_x): changed name to make it consistent
3988 with the ! -> _x mapping when going from Scheme to C.
3990 1997-10-19 Mark Galassi <rosalia@cygnus.com>
3992 * gh.h (gh_reverse):
4000 (gh_assoc): added these gh_ functions implemented as macros.
4002 * gh_predicates.c (gh_null_p):
4003 (gh_string_equal_p): added these two missing predicates.
4005 * gh_list.c (gh_append):
4010 (gh_set_cdr_x): added these routines as I go through and try to
4011 complete the picture R4RS functions that should be mirrored in the
4014 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4016 * tags.h (scm_tc7_substring): Changed the comment and code to
4017 conform with the changes below. Folks! We have suddenly two new
4018 free tc7 codes!!! Jummy, jummy!
4020 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
4022 * Makefile.in: Rebuilt.
4023 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
4025 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
4026 * unif.c (scm_vector_set_length_x): Don't handle multibyte
4028 * tag.c (scm_utag_mb_string, scm_utag_mb_substring): Removed.
4029 (scm_tag): Don't handle multibyte strings.
4030 * read.c: Don't include mbstrings.h.
4031 (scm_lreadr): Don't handle multibyte ports.
4032 * kw.c: Don't include mbstrings.h.
4033 * init.c: Don't include mbstrings.h.
4034 (scm_boot_guile_1): Don't init mbstrings module.
4035 * hash.c (scm_hasher): Don't handle mbstrings.
4036 * gscm.c (gscm_run_scm): Don't init mbstrings module.
4037 * gc.c (scm_gc_mark): Don't handle mbstrings.
4038 (scm_gc_sweep): Likewise.
4039 * eval.c (SCM_CEVAL): Don't handle mbstrings.
4040 * eq.c (scm_equal_p): Use SCM_TYP7S, not SCM_TYP7SD.
4041 * tags.h (SCM_TYP7SD): Removed.
4042 (SCM_TYP7D): Removed.
4043 (scm_tc7_mb_string): Removed.
4044 (scm_tc7_mb_substring): Removed.
4045 * print.c (scm_iprin1): Handle char printing directly. Don't
4047 Don't include "mbstrings.h".
4048 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
4049 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
4051 Don't include "mbstrings.h".
4052 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
4053 (SCM_SYMBOL_SLOTS): Define as 4.
4054 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
4055 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
4056 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
4057 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
4058 struct.c, threads.c, throw.c, unif.c, variable.c: Use new
4059 ("gen"-less) I/O function names.
4060 * ports.c (scm_add_to_port_table): Don't set port's
4062 * ports.h (scm_port_representation_type): Removed.
4063 (scm_string_representation_type): Removed.
4064 (struct scm_port_table ): Removed representation field.
4065 (SCM_PORT_REPRESENTATION): Removed.
4066 (SCM_SET_PORT_REPRESENTATION): Removed.
4067 * genio.h: Use new function names.
4068 * genio.c: Don't include "extchrs.h".
4069 (scm_gen_putc, scm_gen_puts, scm_gen_write, scm_get_getc):
4071 (scm_putc, scm_puts, scm_lfwrite): No longer static.
4072 (scm_getc): No longer static; handle line and column changes.
4073 (scm_ungetc): Renamed from scm_gen_ungetc.
4074 (scm_do_read_line): Renamed from scm_gen_read_line.
4075 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
4076 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
4078 1997-10-12 Mark Galassi <rosalia@cygnus.com>
4080 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
4082 * gh_test_c.c (c_vector_test): some improvements on the vector
4085 * gh.h (gh_vector): this used to exist but do the wrong thing.
4086 Now it (almost) does the right thing, though it takes a list
4087 instead of the individual arguments. I need to see how it could
4089 (gh_list_to_vector): added this function as a macro. Corresponds
4090 to Scheme's (list->vector ...).
4091 (gh_vector_to_list): added this function as a macro. Corresponds
4092 to Scheme's (vector->list ...).
4094 * gh_data.c (gh_vector_ref): renamed from gh_vref to
4095 gh_vector_ref, so that it resembles the Scheme routines more.
4096 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
4097 resembles the Scheme routines more.
4098 (gh_make_vector): this used to be (stupidly) called gh_vector().
4099 This is the right name, since it does the same thing as the Scheme
4100 (make-vector ...) procedure.
4102 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
4104 * ports.h: #include "libguile/print.h"
4106 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
4107 Some indentation fixes.
4109 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
4110 longer a user field; New field: class_flags.
4112 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
4114 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
4116 * gh_data.c (gh_bool2scm): new function which replaces
4117 gh_int2scmb(), which is now tagged as obsolete.
4119 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
4121 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
4122 macros should by convention not test for NIMPness.)
4123 (SCM_COERCE_OPORT): Adjust indentation.
4125 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
4126 SCM_NIMP test before SCM_PRINT_STATE_P.
4128 * struct.c, struct.h, gc.c: Renamed:
4129 scm_struct_i_layout --> scm_vtable_index_layout
4130 scm_struct_i_vcell --> scm_vtable_index_vcell
4131 scm_struct_i_vtable --> scm_vtable_index_vtable
4132 scm_struct_i_printer --> scm_vtable_index_printer
4133 scm_struct_i_vtable_offset --> scm_vtable_offset_user
4135 * struct.c (scm_print_struct): Use new printer slot; Default
4136 printing: Also output hex code of vtable so that type identity
4137 will be indicated as well.
4138 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
4139 Removed struct_printer_var; Removed struct-vtable-offset;
4140 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
4141 vtable-offset-user): New constants.
4143 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
4144 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
4145 If this slot contains a procedure, use that to print structures of
4146 the type represented by this vtable.
4148 * print.c (scm_iprin1): Don't print arguments of macro
4149 transformers. (They are always: exp env.); Bugfix: Unmemoize
4150 transformer source with correct environment.
4152 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
4154 Streamlining of call-with-dynamic-root:
4156 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
4157 there is now only one catch.
4158 (cwdr_outer_body): Removed.
4159 (cwdr_handler): New function.
4160 (scm_internal_cwdr): New function to perform the function of cwdr
4161 but take args that are more useful to C code. Also, the handler
4162 is now invoked *outside* of the new dynamic root, like the docs
4163 say. We no longer have to catch absolutely all errors, the caller
4164 is responsible for using a handler that does not throw, if he
4166 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4167 * root.h (scm_internal_cwdr): New prototype.
4169 Even more but risky streamlining:
4171 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4172 allocation of the jumpbuf of a root continuation. The changes
4173 below are controlled by it. They are now deactivated.
4174 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4175 the JMPBUF of the scm_rootcont to NULL before returning.
4177 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4178 when they are non-NULL.
4179 (scm_gc_mark): Likewise, mark only when non-NULL.
4181 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
4182 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
4184 * gc.c (scm_done_malloc): New function.
4185 gc.h (scm_done_malloc): New prototype.
4187 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
4188 (struct scm_print_state) [revealed]: New field.
4189 (scm_print_state_vtable): Make visible to the outside world for
4190 type checking purposes.
4191 (scm_valid_oport_value_p): New prototype.
4193 * print.c (scm_valid_oport_value_p): New function to check whether
4194 a certain value is acceptable as a port argument.
4195 (scm_print_state_vtable): New variable.
4196 (scm_free_print_state): Set `revealed' field to false.
4197 (scm_iprin1): Call user supplied closure printer with
4198 scm_printer_apply. Print in the traditional way when there isn't
4199 one or when it returns #f.
4200 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4201 Accept a port/print-state pair in addition to just a port.
4202 (scm_prin1): Don't return the print_state to the pool when it has
4204 (scm_printer_apply): Set `revealed' field of print_state to true.
4205 (scm_init_print): Set scm_print_state_vtable.
4206 (print_state_fluid, print_state_fluid_num): Removed.
4208 * throw.h (scm_handle_by_proc_catching_all): New prototype
4209 throw.c (scm_handle_by_proc_catching_all): New function
4211 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
4213 * Makefile.in: Regenerated with automake 1.2c.
4215 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
4217 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
4218 was looping endlessly.
4220 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
4222 * strports.c (scm_eval_string): Don't close the port.
4224 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
4225 former returns a nice normal integer. (Thanks to Daniel
4228 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
4230 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
4231 makefile variable as a build parameter called LIBS. The
4232 build-guile program will use this, for the time being.
4233 * Makefile.in: Regenerated.
4235 Thanks to Shiro Kawai:
4236 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
4237 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
4240 * Makefile.in: Regenerated with automake 1.2a.
4242 * script.c (scm_compile_shell_switches): If we hit the -c or --
4243 arguments, don't set the car of (command-line) to scm_usage_name,
4244 the prettified name of the guile executable; give it the full
4245 path, the way shells usually handle $0.
4247 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4249 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
4250 Scheme-level name `array-map' and renamed `serial-array-map' to
4251 `serial-array-map!'.
4253 * backtrace.c: Introduced exception handlers which now enclose
4254 `display-error' and `display-backtrace' so that error reporting
4255 won't get into infinite loops if an error occurs during displaying
4256 of the error. This can very easily happen with user supplied
4257 print call-back routines.
4259 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4261 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
4262 the names `serial-array-map' and `array-map' should be removed.)
4264 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
4266 * init.c (scm_boot_guile_1): Added scm_init_objects ().
4267 Added #include "objects.h"
4269 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
4270 Add #include "feature.h".
4272 * Makefile.am (libguile_la_SOURCES): Added objects.c.
4273 (modinclude_HEADERS): Added objects.h.
4275 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
4276 This test is needed at many places in the code and should be
4277 abstracted. (Motivated by the need of this test in libguiletk.)
4279 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
4280 (scm_eval_string), load.c (scm_primitive_load,
4281 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
4282 Use SCM_EOF_OBJECT_P.
4284 * eval.c (scm_init_eval): Add feature `delay'.
4286 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4288 * scmhob.h: Removed.
4290 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4292 * list.h (SCM_LISTn): New macros. Make list creation in C code
4293 prettier. The idea comes from STk.
4295 * sequences.h, sequences.c, append.h, append.c: Removed. These
4296 files implemented non-R4RS operations which would encourage
4297 non-portable programming style and less easy-to-read code.
4299 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
4302 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
4303 sequences.h, #include append.h.
4305 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
4308 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
4310 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
4312 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
4314 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4316 * eval.c: Added #include "objects.h"
4318 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
4321 * smob.c (scm_smob_prehistory): Create two objectsmobs with
4322 adjacent smob numbers.
4324 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4326 * procprop.h: Added declaration of scm_i_inner_name.
4328 * gsubr.c: New global symbol scm_i_inner_name.
4330 * debug.c (scm_procedure_name): Try procedure property
4331 `inner-name' if `name' fails.
4333 * print.c (scm_iprin1): Use scm_macro_name.
4335 * eval.c (scm_m_define): Give names to macros as well; Only the
4336 first top-level definition gives a procedure/macro a name.
4337 Otherwise confusing names can turn up in backtraces.
4338 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4339 `name'; Give names to macros as well.
4341 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4342 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4345 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4347 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4349 (prinmacro): Removed. The code has been moved/merged into print.c
4350 in order to decrease code redundancy. We want macros to print in
4351 a way equivalent to procedures, and it would be silly to duplicate
4352 the required code. (We don't want to maintain two places.)
4353 (macrosmob): Print field is now a NULL pointer.
4355 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4356 scm_macro_transformer): New prototypes.
4357 (scm_tc16_macro): Declared.
4359 * print.c (scm_iprin1): Added code for printing of macros. Macros
4360 are now printed in a way equivalent to procedures.
4362 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4364 * procs.h (scm_closure_p): Added declaration.
4366 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4368 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4369 Shouldn't pass "heap" as the subr name.
4371 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4373 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4374 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4375 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4376 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4377 SCM_BOOL_T. Any non-false value is true.
4379 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4381 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4382 scm_gensym): Added prototypes.
4384 * symbols.c (scm_gensym): New function. This will speed up
4385 certain types of applications (such as macro systems) which
4386 generate lots of symbols.
4388 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4390 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4392 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4394 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4395 specifier, since (2) or (2 . 3) would cause SEGV.
4396 (scm_transpose_array): more argument checking fixes.
4398 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4400 * Makefile.in: Regenerated.
4402 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4404 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4406 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4408 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4410 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4412 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4413 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4416 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4417 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4418 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
4419 scm_array_p, scm_array_rank, scm_array_dimensions,
4420 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
4421 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
4422 scm_array_prototype): Added case scm_tc7_wvect.
4424 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
4426 * errno.h: prototype for scm_strerror.
4427 * error.c (scm_strerror): new procedure.
4429 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4431 * list.c (scm_list_append_x): Allow non-pair as last argument.
4432 This is consistent with the R4RS append and is probably the
4433 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4435 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4437 * stime.h: prototype for scm_times.
4438 * stime.c (scm_times): new procedure.
4439 * ioext.c (scm_fseek): if the first argument is a file descriptor
4441 (scm_ftell): if the first argument is a file descriptor call lseek
4443 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
4444 * filesys.c (scm_chmod): if the first argument is a file descriptor,
4446 (scm_chown): if the first argument is a port or file descriptor,
4448 (scm_truncate_file): new procedure.
4449 Add DEFER/ALLOW INTS to a few other procedures.
4450 (scm_fsync): new procedure.
4451 (scm_open_fdes): new procedure.
4452 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
4454 (scm_fcntl): the first argument can now be a file descriptor. The
4455 third argument is now optional.
4457 * posix.c (scm_execl, scm_execlp): make the filename argument
4458 compulsory, since omitting it causes SEGV.
4459 (scm_sync): return unspecified instead of #f.
4460 (scm_execle): new procedure.
4461 (environ_list_to_c): new procedure.
4462 (scm_environ): use environ_list_to_c. disable interrupts.
4463 (scm_convert_exec_args): take pos and subr arguments and
4464 improve error checking.
4466 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4468 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4469 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4470 argument to SCM_ASSERT. Furthermore, the name of the function
4471 should be passed as first argument when signalling
4472 SCM_WNA. (Thanks to Thomas Morgan)
4474 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4475 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4476 dispatches on the number of actual args has a default case
4477 reporting an internal error. This is a vestige from a version
4478 that mallocated a SCM vector to hold the arguments. In the
4479 current version this check is too late: if it ever happens we will
4480 have already overstepped the bounds of the array.
4482 Also, the patch [...] adds a check for too many actual arguments."
4484 mdj: Removed check for "internal programming error".
4486 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4488 * gh_io.c (gh_write): New function.
4490 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
4491 throw.c (scm_internal_stack_catch): New sibling to the other catch
4492 functions. Code moved from gh_eval.c.
4493 throw.h: Added header.
4494 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
4495 scm_internal_stack_catch.
4497 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4499 * ioext.h: fix up prototypes.
4500 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
4501 Scheme name is now dup->fdes.
4502 (scm_dup_to_fdes): make the second argument optional and
4503 fold in the functionality of scm_primitive_dup.

4551 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied

4572 * ioext.c (scm_primitive_dup2): return the new file descriptor
4573 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
4575 (scm_fdopen): bug fix: don't try to make port unbuffered until its
4576 stream has been set.
4577 (scm_duplicate_port): deleted, there's now an implementation in
4579 (scm_primitive_dup2): do nothing if newfd == oldfd.

4635 but that should be much less likely.

4654 was found during autoconf (in this case, getgroups).
4655 (scm_setpwent): For setpwent.
4656 (scm_setegid): For setegid.
4657 * net_db.c (scm_inet_netof): Don't include unless support

4677 think this is left over from the (eq? '() #f) days.
4679 * read.c (recsexpr): Give this a dummy definition if
4680 DEBUG_EXTENSIONS isn't #defined.
4682 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>

4709 have to do this explicitly. Also, if regexp/basic is supplied, then
4710 turn off REG_EXTENDED.
4711 (scm_init_regex_posix): New regexp/basic symbol.
4712 (REG_BASIC): #define this if it is not already present.

4735 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
4737 (scm_init_regex_posix): Define constants for the REG_mumble flags;

4747 (versiondat.h): Print a message, but don't print all the commands.
4748 * load.c: #include "alist.h".
4749 (init_build_info): New function.

4755 * root.c: Establish a reliable catch-all handler for the new root.
4756 After all the Scheme handler function might signal an error too,
4757 and we don't want to lose that.
4758 (cwdr_inner_body): Renamed from cwdr_body.
4759 (cwdr_outer_body): New function, to establish the user's handler,
4760 and pass control to cwdr_inner_body.
4761 (cwdr): Establish the reliable catch-all handler here, and pass
4762 control to cwdr_outer_body.
4763 (struct cwdr_body_data): New field, handler, to allow cwdr to pass

4768 * throw.h (scm_handle_by_message_noexit): New prototype.
4770 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
4771 across this. Only works on GCC. Otherwise, we hope for the best.
4772 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4773 the feeling that real thread systems will not need this...
4775 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4777 Try to detect when people are using one version of libguile and a

4789 primitive definitions under their Scheme names.
4791 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4792 1:2. Helps avoid confusion between installed and uninstalled libs.
4794 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
4797 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
4798 backslash from definition; this should be used like: GDB_INTERFACE;
4800 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4802 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
4803 new port unbuffered until its stream has been set.
4805 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
4807 * ports.h: new prototype.

4817 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4819 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
4820 argument plain char *.

4823 * tag.c (scm_tag): Remove unreachable statement.
4824 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4825 top of the word, it should be unsigned.
4827 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4828 is defined, to avoid warnings; it's only used in the
4829 conflict-checking code. Which might go away anyway.
4830 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4831 conditionals; put the label definition in an #if too, to stifle
4834 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4835 ChangeLog-threads in the distribution.
4836 * Makefile.in: Regenerated.

4846 * load.c (scm_init_load_path): Append $(datadir)/guile to
4847 %load-path, so modules do not have to be installed in Guile's
4848 current version directory.
4850 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
4852 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
4853 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
4854 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always

4877 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4878 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4881 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4883 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4884 supplied. (Change from Tim Pierce.)
4886 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4888 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4889 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4890 default and not `()'. `#f' is the canonical non-value in Scheme,
4893 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4895 * struct.c (struct_printer): New variable that holds a handle on
4896 the Scheme variable *struct-printer*. This variable can be set by
4897 Scheme code to override the printing of structures.
4898 (scm_print_struct): If struct_printer is set, call it. If it is
4899 not set, or returns #f, print the structure in the old fashion.
4900 Include "eval.h" for scm_apply.
4902 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4904 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4905 scm_struct_i_n_words to get the number of fields, not
4906 -scm_struct_n_extra_words.
4908 On the route to fancier struct printing:
4909 * struct.c (scm_print_struct): New function to print a structure.
4910 Include "genio.h" to support it. This function doesn't do
4911 anything interesting right now, but I think it should be here
4913 * struct.h: Include "print.h" and add prototype for
4915 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4916 print structures ourself.
4918 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4920 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
4921 before applying the handler in case it doesn't return.
4923 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>

4927 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
4930 * posix.c (scm_uname): interpret only negative values as an error.
4931 Solaris normally returns a positive value.
4933 * script.c (scm_compile_shell_switches): if we are not going into
4934 an interactive repl, set scm_mask_ints to zero so that asyncs can
4937 * simpos.c (scm_system): don't ignore/unignore signals around
4940 * posix.c (scm_open_pipe): don't ignore/unignore signals around
4943 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
4944 done in boot-9.scm instead.
4946 * scmsigs.c, async.c: Major rewriting of signal handling code.
4947 (scm_sigaction): new procedure.
4948 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
4950 (scm_raise): return unspecified, throw error on failure.
4952 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4954 * regex-posix.c (scm_init_regex_posix): Register the "regex"
4955 feature, to help boot-9.scm decide whether to import the regex
4958 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
4960 * eval.c: Include scmconfig.h at the beginning of the file so that
4961 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
4964 * regex-posix.c: #include "_scm.h" before conditionally #including
4965 <regex.h>; the former defines HAVE_REGCOMP.
4967 * regex-posix.c: #include <regex.h> conditionally, so the file is
4968 CPP'able (for dependency scanning) even on systems that don't have
4971 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4973 Add new R4RS-compliant syntax for keywords.
4974 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
4975 regardless of the setting of the `keywords' read option.
4976 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
4977 can be re-read no matter what the setting of the `keywords' read
4980 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
4982 Add support for POSIX regular expressions.
4984 * regex-posix.c, regex-posix.h: New files. (Some code
4985 is taken liberally from rx/rgx.c in the old Guile dist.)
4987 * init.c: Include regex-posix.h.
4988 (scm_boot_guile_1): Call scm_init_regex_posix.
4990 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
4991 Add regex-posix.[ch] sources.
4992 * Makefile.in: Regenerated.
4994 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
4995 to do this automatically? It didn't for me, bleh.)
4997 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
4999 * fports.c (print_pipe_port): New function.
5000 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
5001 latter doesn't even take the right arguments.
5003 * Makefile.am: Increment shared lib revision number. I think
5004 sometimes the uninstalled Guile finds the installed shared lib;
5005 Gord says doing this might help. As things turned out, I can't
5006 say whether it does.
5007 * Makefile.in: Regenerated.
5009 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
5010 passing it as the closure argument to scm_boot_guile. (Bill
5013 * ports.c (print_void_port, putc_void_port, puts_void_port,
5014 write_void_port, flush_void_port, getc_void_port, close_void_port,
5015 noop0): Use ANSI prototypes instead of K&R declarations, so the
5016 initialization of void_port_ptob gets aggressively type-checked.
5017 Fix arguments of print_void_port and write_void_port. (Bill

5051 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
5053 * script.c (scm_find_executable): Use prototype-style definition
5054 here; apparently it's not quite right to have const in a prototype
5055 and then use a K&R declaration. I wonder if stuff like this will
5056 go away if we compile with -Wrequire-prototypes, or whatever that
5057 is... (Bernard URBAN)
5059 * scmhob.h: New text from Bernard URBAN.
5061 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5063 * script.c: Don't #define const on hpux. Configure takes care of
5064 this. (Thanks to Larry Schwimmer.)
5066 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5067 decide whether to #include <unistd.h>, instead of listing a bunch
5068 of systems. Don't #include stdio twice. Removed dyked-out
5069 definition of scm_find_impl_file.
5071 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5073 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5074 library version info to 1:0.
5075 * Makefile.in: Regenerated.
5077 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

5081 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5082 throw.c: Update copyright years; these files have been worked on
5083 significantly in 1997, but only had copyright years for 1996.
5084 Also, change name of copyright holder on some from Mikael
5085 Djurfeldt to Free Software Foundation; he has signed papers
5086 assigning the changes to the FSF.
5088 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5089 reason not to give the user the option.
5091 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5092 Return #f on end-of-file when scanning table (i.e. when called
5093 with no arguments). Try to catch errors, when we can.
5094 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5096 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5097 external declarations. These are useful.
5099 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5101 * posix.c: don't include <sys/select.h> or define macros for
5102 select, since they were not used in this file.
5104 * filesys.c (scm_select): make the fifth parameter microseconds,
5105 not milliseconds. let the fourth parameter be either a real value
5106 or an integer or #f. The first, second and third arguments can
5107 now be vectors: the type of the corresponding return set will be
5109 (set_element, get_element): new static procedures.
5111 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5113 * strports.c (scm_eval_string): New function.
5114 (scm_eval_0str): Trivially re-implemented in terms of
5116 * strports.h (scm_eval_string): New extern decl.
5118 * net_db.c (h_errno): Add extern decl for this.
5120 * fports.c (local_pclose): New function.
5121 (scm_pipob): Use it in the initializer here.
5124 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5125 Use a meaningful error message when signalling an error. For
5126 this, scm_gethost must check h_errno rather than errno.
5128 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5130 * Makefile.in: Regenerated, using automake-1.1p.
5132 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5134 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5135 not SCM_UNSPECIFIED.
5137 * script.c (scm_compile_shell_switches): don't append (quit) if
5139 (scm_shell): call scm_exit_status and exit on the result of the
5142 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5144 Ensure that shared substrings are handled properly when passed to
5145 a system call or other foreign function. Many thanks to Tim
5147 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5148 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5149 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5150 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
5151 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
5152 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
5153 (scm_display_error_message): use RO macros when strings may be RO.
5154 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
5155 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
5156 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

5160 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
5161 scm_strftime), vports.c (scm_make_soft_port): use
5162 SCM_COERCE_SUBSTR to make sure shared substrings are
5165 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5167 * error.c (scm_error): Add newline to error message.
5169 * init.c (scm_init_standard_ports): Doc fix.
5171 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5173 * dynl-shl.c: Completely replaced with new code from Bernard
5176 * script.c (scm_ice_9_already_loaded): New variable.
5177 (scm_compile_shell_switches): Use it.
5179 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5181 * filesys.c (scm_input_waiting_p): add missing third argument to
5184 * stime.c (scm_localtime): copy the result of localtime before
5185 calling gmtime in case they share a buffer.
5186 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5189 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5191 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5193 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5195 * Makefile.am (check-local): New target, which causes 'make check'
5196 to run gh_test_c and gh_test_repl, with some trivial input.
5197 * Makefile.in: Rgnrtd.
5199 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5201 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5204 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
5206 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
5207 sure how this was supposed to work.
5208 (scm_async_click): don't send SCM_TICK_SIGNAL.
5209 (scm_init_async): don't initialize %tick-thunk.
5211 * the following change doesn't affect the Scheme interface:
5212 gc-thunk is called at the end of garbage collection. however it's
5213 no longer implemented by pretending it's a signal.
5215 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
5216 system async corresponding to scm_gc_thunk.
5217 * async.h: declare scm_gc_async.
5218 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
5219 gc-thunk directly, instead of going through a signal handler.
5220 (scm_gc_async): new variable, points to the GC system-async.
5221 (scm_init_async): save the GC async as scm_gc_async instead
5222 of using system_signal_asyncs.
5223 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
5225 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
5227 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
5228 Don't screw up if we're interrupted.
5229 * Makefile.in: Regeneradet.
5231 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
5233 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
5235 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
5236 we're not using AM_INIT_GUILE_MODULE any more.
5237 * Makefile.in: Reneregated.
5239 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5241 Functions for finding variable bindings, grace à Tim Pierce.
5242 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
5243 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
5245 Get 'make dist' to work again.
5246 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
5247 * Makefile.in: Regenerated, like a surry without a fringe on top.
5249 Changes for reduced Guile distribution: one configure script,
5251 * configure.in, configure: Removed.
5252 * acconfig.h, acinclude.m4: Moved to parent directory, where the
5253 real configure script lives.
5254 * Makefile.in, scmconfig.h.in: Regenerated.
5256 * init.c: #include "script.h", to get prototype for script.c's
5259 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
5261 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
5262 scm_must_malloc, not raw malloc.
5264 * script.c (scm_compile_shell_switches): Dyke out debugging output
5267 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5269 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
5271 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
5272 system has them. Hope this is safe. Previously
5273 sys/timeb.h was included if HAVE_FTIME was defined or if
5274 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
5275 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
5277 * ioext.c (scm_setfileno): add missing third argument to
5278 scm_misc_error call.
5280 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
5282 * eq.c (scm_equal_p): Correctly compare strings of different
5283 varieties. (Thanks to Tim Pierce.)
5285 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
5287 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
5288 #! block comment must occur on a line all by itself.
5290 Move most of the guts of shell command processing into libguile,
5291 so guile.c can be very small (and eventuallly auto-generated. (I
5292 mean, generated mechanically, not self-generated. Hmm.))
5293 * guile.c, script.c, script.h: New source files.
5294 * init.c (scm_boot_guile_1): Call scm_init_script.
5295 * libguile.h: #include "script.h".
5296 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
5297 targets, for new executable.
5298 (libguile_la_SOURCES): Mention script.c.
5299 (modinclude_HEADERS): Add script.h.
5300 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
5301 not dynamic linking is enabled. This is because we're generating
5302 executables now. Move CY_AC_WITH_THREADS call after those, so the
5303 values of cy_cv_threads_libs captures the libs chosen above.
5304 * Makefile.in, configure, aclocal.m4: Regenerated.
5306 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
5307 We don't maintain this interface any more, and it just confuses
5310 * alloca.c: #include <scmconfig.h>, not <config.h>.
5311 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
5312 it'll get included in disties.
5314 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5316 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
5317 be distributed, because they confuse people.
5318 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
5320 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
5322 * configure.in: check for presence of gethostent (not present on
5323 OpenBSD by default).
5324 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
5325 * configure, scmconfig.h.in: Regenerated.
5327 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5329 * backtrace.c (scm_backtrace): Split message string across
5330 newlines properly. GCC is more tolerant of this than other
5333 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
5335 Merge threads directory into libguile.
5336 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5337 threads.h: New source files.
5338 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
5339 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
5341 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5342 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5343 coop-threads.c.cygnus, coop-threads.h.cygnus.
5344 * configure.in: If we're using threads, include threads.o in
5346 * _scm.h, libguile.h: threads.h lives in this directory now.
5347 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5348 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5349 currently used, but brought along for information's sake.
5350 * ChangeLog-threads: log from old 'threads' directory.
5351 * Makefile.in, configure: Rebuilt.
5353 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5355 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5358 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5360 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5362 Merge GH interface library into libguile.
5363 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
5364 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5365 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5366 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5368 (EXTRA_libguile_la_SOURCES): ... here.
5369 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5370 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5371 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5372 New variables, describing how to build the gh test programs.
5373 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5374 build the test programs, and we probably should have been linking
5375 libguile.la against them all along, to support AIX shared libs.
5376 Add cflags for threads to CFLAGS; add libs for threads to new
5377 variable THREAD_LIBS, used in Makefile.am.
5378 * ChangeLog-gh: log from old `gh' subdirectory.
5379 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5381 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5383 * acconfig.h: Undo change of Apr 9; including the definition of
5384 PACKAGE in the guile headers conflicts with applications' own
5386 * scmconfig.h.in: Regenerated.
5388 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
5390 * filesys.c (scm_fcntl): New function from Roland McGrath.
5391 (scm_init_filesys): New symbols for use with fcntl.
5392 * filesys.h: Added prototype.
5394 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
5395 when PROC is receiving no arguments.
5397 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5399 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5400 have S_IFSOCK. This is the case under Ultrix.
5402 * posix.c (scm_status_exit_val, scm_status_exit_val,
5403 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5404 Ultrix versions of WIFSTOPPED, etc., which assume that their
5405 arguments are lvalues (hmm).
5407 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5409 * eval.c: Doc fixes.
5411 * throw.c: Doc fixes; rearranged.
5413 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
5415 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
5417 * acconfig.h: Added entry for PACKAGE.
5418 * scmconfig.h.in: Regenerated.
5420 Changes to work with automake-1.1n, which has better libtool support.
5421 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5422 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5424 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5426 * Makefile.in: Rebuild.
5428 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5430 * stime.c (scm_mktime): take an optional zone argument.
5431 (scm_localtime): check putenv return value.
5432 (scm_strftime, scm_strptime): moved from posix.c. move #include
5434 stime.h, posix.h: update prototypes.
5435 (bdtime2c, setzone, restorezone): new static procedures.
5436 (scm_mktime, scm_strftime): use them.
5437 (scm_strftime): don't call mktime before strftime. Use
5438 filltime for return value.
5439 (filltime): convert NULL zname to #f.
5440 (scm_strptime): return a count of characters consumed, not
5441 the remaining string.
5443 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5445 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
5446 (scm_mktime): likewise.
5448 Uncomment localtime and mktime.
5450 * configure.in: add AC_STRUCT_TIMEZONE.
5452 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5454 * stime.c (scm_init_stime): don't define ticks/sec.
5455 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5456 return value problem and is still portable.)
5458 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5460 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5461 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5462 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5463 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5464 cpp_err_symbols.c): Corresponding changes.
5465 * Makefile.in: Regenerated.
5467 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5469 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5470 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5471 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5472 * putenv.c: new file, from sh-utils 1.12.
5474 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5475 since allocation isn't for Scheme objects.
5476 (scm_putenv): copy strings before placing in the environment.
5478 * stime.c (scm_current_time): throw an error if time returns -1,
5479 instead of returning #f.
5480 (scm_get_internal_real_time, scm_get_internal_real_time): use
5481 scm_long2num for return value instead of SCM_MAKINUM.
5483 * stime.h: prototypes updated.
5485 * stime.c (scm_time_in_msec): apparently unused, deleted.
5487 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5489 * configure.in: check for gettimeofday.
5491 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5492 which may be more usefully portable than a gettimeofday interface.
5494 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5496 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5498 * Makefile.in: Regenerated.
5500 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5502 * stime.c (filltime): recovered static procedure.
5503 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5506 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5507 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5509 * posix.c (scm_mknod): split the mode argument into type and perms
5510 arguments, like the extra fields returned by stat.
5512 * fports.c (scm_pipob): set the close, free and print procedures.
5513 (scm_close_pipe): new procedure.
5515 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5516 define them in boot-9.scm
5518 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5520 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5521 wan't defined. Don't include fd.h.
5523 * Previously fd.h was regenerated whenever configure was run,
5524 forcing a couple of files to be recompiled.
5526 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5527 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5528 Check for _fileno as well as _file.
5530 * ioext.c: don't fd.h.
5531 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5534 * Change the stratigy for getting information about errno
5535 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5536 generating lists of symbols during the build process, which will
5537 not always work, include comprehensive lists in the distribution.
5538 To help keep the lists up to date, the "check_signals" and
5539 "check_errnos" make targets can be used.
5541 * configure.in: don't check for a command to extract errno codes.
5542 * Makefile.am: update file lists, remove errnos.list and errnos.c
5543 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5544 check_errnos targets.
5545 (CLEANFILES): remove errnos.c and errnos.list, add
5546 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5547 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5548 * errnos.default: deleted.

5551 * cpp_err_symbols, cpp_sig_symbols: new files.
5552 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5553 * error.c (scm_init_error): #include cpp_err_symbols instead of
5555 * posix.c (scm_init_posix): don't intern signal symbols. #include
5558 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5560 * strop.c (scm_i_index): allow the lower bound to be equal to the
5561 length of the string, so a null string doesn't always give an error.
5563 * posix.h: new prototypes.
5564 * posix.c (scm_status_exit_val, scm_status_term_sig,
5565 scm_status_stop_sig): new functions, as in scsh. They break down
5566 process status values as returned by waitpid.
5568 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5570 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5571 configure doesn't know about it.
5573 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5575 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5577 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5578 which defines C variables with global linkage.
5580 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5582 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5585 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5587 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5588 has time to check why this doesn't work well with continuations.
5590 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5592 * Fix shell syntax error; some shells won't tolerate
5593 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5595 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5597 * posix.c (scm_uname): throw an error if uname fails instead
5600 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5602 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
5605 * async.c (scm_ints_disabled): definition moved from error.c.
5607 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5609 * acconfig.h: Removed PACKAGE.
5611 * scmconfig.h.in: Regenerated.
5613 * snarf.h: g++ says it's non-portable not to specify the first
5614 argument in a varargs declaration. I introduced the first
5615 argument by using preprocessor conditionals.
5617 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5619 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5620 (scm_freopen): use RO string macros for filename and modes.
5621 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
5623 * posix.c (scm_getgrgid): simplify conversion of name to C string.
5624 (scm_mknod): use RO string macros for path.
5626 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
5627 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5629 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5630 use SCM_ROSTRINGP and SCM_ROCHARS.
5632 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5634 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5637 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5638 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5639 support for byte vectors.
5641 * print.c (scm_iprin1): Limit number of vector elements printed
5642 according to pstate->length.
5644 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5646 * backtrace.c (scm_display_error_message): don't segv if message
5649 * error.h: prototype for scm_error_scm.
5651 * error.c (scm_error_scm): new procedure, reimplements scm-error
5652 in C and uses scm_error.
5654 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5656 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5657 pointer to the Scheme variable read-hash-procedures and intern it
5658 in scm_init_read. Modify scm_read_hash_extend and
5659 scm_get_hash_procedure to use the pointer.
5661 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5663 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5664 (SCM_KEYWORD_STYLE): defined.
5666 * read.c (scm_read_opts): add a keywords option. This isn't a
5667 boolean option, in case someone wants to add support for DSSSL
5669 Setup scm_keyword_prefix symbol.
5670 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5672 I've left keyword support disabled by default, since it doesn't
5673 seem to break the module system and it gives R4RS standard behaviour.
5674 It can be reactivated with (read-set! keywords 'prefix).
5676 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5678 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5679 before constructing arbiter.
5681 * eval.c (scm_m_define): Bugfix: Check that the object is a
5682 closure before setting the procedure property!
5684 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5686 * ports.c: Removed `ungetc-char-ready?'.
5688 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5690 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5691 (idea from Mikael: make it a pair so scm_permanent object only
5693 (scm_read_hash_extend): don't call scm_permanent_object.
5694 (ideas from Mikael): if chr is already in the list, replace its
5695 procedure instead of appending it again. If proc is #f, remove
5697 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5699 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5701 * gdbint.c (gdb_read): update scm_lreadr usage.
5703 * load.h: update prototypes.
5705 * load.c (scm_primitive_load, scm_read_and_eval_x,
5706 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
5708 * read.h: add prototype for scm_read_hash_extend. Change args for
5711 * read.c (scm_read_hash_procedures): new variable.
5712 (scm_read_hash_extend): new procedure.
5713 (scm_get_hash_procedure): new procedure.
5714 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5715 for extended # processing.
5716 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5717 scm_read_token): remove case_i, sharp arguments. Change callers.
5719 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5721 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5722 (SCM_CASE_INSENSITIVE_P): define.
5724 * read.c: add case-insensitive option to scm_read_opts.
5725 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5726 to determine whether to convert symbol case.
5727 (default_case_i): definition removed.
5728 * read.c (scm_read_token): if case_i, downcase ic before doing
5731 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5733 * configure.in: Added configuration option `guile-debug'.
5734 Configure with --enable-guile-debug if you want a bunch of extra
5735 functions used for debugging when developing Guile.
5737 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5739 * procs.c (make-cclo): New undocumented debugging procedure: Make
5740 compiled closure with internal procedure PROC and length LENGTH.
5741 Only compiled if GUILE_DEBUG is defined.
5743 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5745 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5747 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5749 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5750 with 3 or more args internally to the evaluator.
5752 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5754 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5755 with 3 or more args internally to the evaluator. This is mainly
5756 because we don't want to pass entry and exit points of the
5757 debug support twice, but it also seems to increase the speed of
5758 the evaluator for such calls (e. g. (+ 1 2 3)).
5760 * backtrace.c (scm_display_application): New procedure:
5761 display-application; Set fancy printing parameters individually
5762 for different types of display (backtrace, error, application).
5763 (These should of course be customizable!)
5765 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5766 clear the CHECK-flags.
5768 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5770 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5772 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5774 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5775 from pairs with a GLOC in the car.
5777 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5778 otherwise `symbol-hash' will behave badly.
5779 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5780 we get segmentation fault!
5782 * symbols.c: Added #include "weaks.h". New functions:
5783 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5784 moved to an extraneous library when we split libguile.)
5786 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5788 * filesys.c (scm_stat): stat now takes fport arguments too as
5789 documented in the manual.
5791 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5793 * debug.c (scm_single_step): Bugfix: Call continuation with
5794 scm_call_continuation instead of throwing to it.
5796 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5798 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5799 argument wasn't declared to be optional.
5801 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5803 * stime.c (scm_init_stime): Add feature "current-time".
5805 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5807 * throw.h: prototype for scm_exit_status.
5808 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5809 args to derive an exit status. Allows (quit) to work from a
5811 (scm_exit_status): new function.
5814 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5816 * eval.c (scm_deval): Removed some old code.
5817 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5819 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5822 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5825 * procs.c: Introduce the existent C function scm_thunk_p at the
5826 Scheme level as well.
5828 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5830 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5831 used from C to easily lookup the value of a symbol in the current
5834 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5836 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5837 scm_init_unif in this file. This will also fix a previous problem
5840 * configure.in: Added AM_MAINTAINER_MODE
5842 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5844 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5847 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5849 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5850 source files that are not always included in libguile but should
5851 have their dependencies calculated by automake. This variable is
5852 recognized by automake, no further magic is needed.
5853 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5854 to deal exclusively with *.lo files, as it seems. The *.o files
5855 are built automatically when the corresponding *.lo file gets
5858 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5860 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5863 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5865 * unif.c (scm_array_set_x): minor change to argument error checking.
5867 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5869 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5870 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5871 They should only be included in the library at configure.in's
5873 (libguile_la_LDADD): Include the appropriate .lo files here.
5874 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5875 so we know when to build them (and their .lo bretheren).
5876 * configure.in (LIBLOBJS): New substituted variable. We let
5877 configure decide which .o files to include in LIBOBJS, and then
5878 put the corresponding list of .lo files in LIBLOBJS. The latter
5879 is what we pass to libtool.
5880 * Makefile.in, configure: regenerated.
5882 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5884 * symbols.c (scm_sysintern0): New function. Contains the core of
5885 old scm_sysintern but doesn't take a second value argument.
5886 (scm_sysintern): Now uses scm_sysintern0.
5887 (scm_sysintern_no_module_lookup): Renamed to
5888 scm_sysintern0_no_module_lookup and doesn't take a second value
5889 argument any longer.
5891 * symbols.h (scm_sysintern0: Added declaration.
5893 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5894 scm_sysintern when interning option keys. Otherwise we risk
5895 destroying the values of already interned variables.
5897 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5898 scheme-level boolean (use SCM_NFALSEP).
5900 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5902 (scm_backtrace): New function. (C version of old function from
5903 boot-9.scm) Motivation: Make it possible to display backtraces
5904 without depending on boot-9.scm. (I'm uncertain if this
5905 motivation is good enough...)
5907 * root.h (scm_root_state): Add member the_last_stack_var.
5908 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5910 * root.c (mark_root): Mark scm_the_last_stack_var.
5912 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5915 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5917 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5918 1. mark_lazy_catch didn't mark the smob.
5919 2. Both functions above have standard variants:
5920 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5921 free_lazy_catch --> scm_free0.
5923 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5925 * throw.c (scm_internal_lazy_catch): New function.
5926 (scm_lazy_catch): Rewritten to use it.
5927 (scm_ithrow): Handle the new lazy catch representation.
5928 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
5929 that doesn't have a jmpbuf is a lazy catch clause.
5930 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
5931 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
5932 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
5934 (scm_init_throw): Register the new lazy-catch smob type.
5935 * throw.h (scm_internal_lazy_catch): decl for new function.
5937 * throw.c (scm_internal_catch): Doc fixes.
5939 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
5940 configure.in. Including this might cause problems if applications
5941 that link against libguile include their own copies of alloca, but
5942 if they're using autoconf, they should be adding libguile to LIBS
5943 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
5944 the copy in libguile, and things will be okay. (I think.)
5946 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5948 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
5950 strop.h: move prototypes too.
5952 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5954 * posix.c (scm_init_posix): don't intern EINTR since it's now done
5957 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
5958 etc. I deleted them from filesys.c long ago, but didn't
5959 notice they were here too (although ineffective since
5960 sys/stat.h wasn't included).
5962 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
5964 * eval.c: Don't define alloca in GCC case. gcc will automatically
5965 use __builtin_alloca if appropriate.
5967 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5969 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
5970 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
5971 that values of automatic variables are preserved. See comments
5972 for safe_setjmp for details.
5974 Change from Thomas Morgan:
5975 * variable.c: Include eq.h.
5976 (var_equal): New function.
5977 (variable_smob): Use var_equal as the discriminator for variables.
5979 * throw.c (s_throw): Remove extraneous declaration.
5981 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
5982 * eval.c: Add necessary CPP cruft to support that.
5983 * configure, Makefile.in, scmconfig.h.in: regenerated.
5985 Change from Thomas Morgan:
5986 * procprop.c (scm_procedure_properties): Convert the Scheme
5987 boolean returned by scm_procedure_p into a C boolean before using
5988 it as a condition for SCM_ASSERT.
5989 (scm_procedure_property): Likewise.
5991 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
5992 indications of Unixness.
5995 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5997 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
5999 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6001 * read.c (scm_lreadr): use scm_misc_error to improve one of the
6002 "unknown # object" error messages.
6004 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
6005 (scm_i_index) and declare it static. Add a 'direction' argument
6006 to indicate what way the search should go.
6007 (scm_i_index): throw out-of-range error instead of wrong-type-arg
6009 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
6010 strop.h: remove scm_i_index, scm_i_rindex prototypes.
6012 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6014 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
6016 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
6017 to avoid clash with various scsh forks.
6019 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
6021 The following two changes (ramap.c, throw.c) are motivated by the
6022 apparent unportability of forward declarations of static arrays of
6023 the form `static foo bar[];'.
6025 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
6026 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
6028 * throw.c (scm_throw): Moved above scm_ithrow.
6030 * options.h: Removed the extern declarations of scm_yes_sym and
6031 scm_no_sym since these are static.
6033 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6035 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6037 * Makefile.am: remove AWK=@AWK@.
6038 Add a rule for generating errnos.list.
6039 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6041 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6042 don't extract errnos, just set a variable (avoids the
6043 need to recompile error.c just because configure is run.)
6045 * unif.h: update prototypes.
6046 * unif.c (scm_uniform_array_read,write): change the offset and
6047 length arguments to start and end, for consistency.
6049 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6051 * ioext.h: update prototypes.
6052 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6053 scm_read_line_x, it's a more general procedure using an
6054 interface from scsh. read-line and read-line! are now defined
6056 Note that the new read-line trims the terminator
6057 by default, previously it was appended to the returned string. An
6058 optional argument specifies how to process the terminator (scsh
6059 compatible). For the old behaviour: (read-line port 'concat).
6060 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6061 returns a pair, but is converted to multiple values if the scsh
6064 socket.h: update prototypes.
6065 * socket.c (scm_recvfrom): for consistency with other procedures,
6066 take start and end as separate optional arguments.
6067 (scm_recv, scm_recvfrom): don't allow the second argument
6068 to be a size, only a buffer. Change the scheme names to
6069 recv! and recvfrom!. Don't return the buffer.
6071 * ioext.h, posix.h: move prototypes too.
6072 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6073 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6074 "read.h" and "unif.h".
6075 * ioext.c: include "chars.h"
6077 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6079 * dynl.c: The dynamic linking and module registration functions
6080 are now defined even when dynamic linking is not available for the
6081 host system. Some of their functionality can be done without
6082 dynamic linking; when it's really needed, they throw errors.
6084 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6086 * configure.in: Only define DYNAMIC_LINKING when one of the system
6087 dependent functions is detected.
6088 * dynl.c (scm_dynamic_func): New function to get the address of a
6089 function in a dynamic object.
6090 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6091 produced by scm_dynamic_func as the thing to call.
6093 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6095 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6096 (scm_register_module_xxx, scm_registered_modules,
6097 scm_clear_registered_modules): New functions.
6099 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6101 * symbols.c (scm_sysintern): Renamed to
6102 scm_sysintern_no_module_lookup.
6103 (scm_sysintern): New function to take the place of the old
6104 scm_sysintern. It uses the current toplevel lookup closure to give
6105 the symbol its value. This is a temporary hack to put packages
6106 like gtcltk into their own module.
6107 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6108 us whether `scm_top_level_lookup_closure_var' has been initialized
6110 * eval.c (scm_init_eval): Set it.
6112 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6114 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6115 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6117 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6119 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6120 scm_sys_dup): deleted: FD capability will be added to other
6122 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6123 scm_fd_free, fd_smob, scm_intern_fd.
6124 (scm_open): renamed from scm_sys_open. Return a port instead of
6125 an FD object. Make the mode argument optional.
6126 (scm_sys_create): deleted, it's just a special case of open.
6127 (scm_init_filesys): move interning of constants O_CREAT etc.,
6128 here (were previously using SCM_CONST_LONG macro).
6129 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6131 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6132 include "fports.h" and <stdio.h>
6133 (scm_stat, scm_select): don't support FD objects.
6135 * error.h: adjust scm_syserror_msg prototype.
6136 * error.c (scm_syserror_msg): take an extra argument for errno.
6137 Using the global value didn't always work, since it could be
6138 reset by procedure calls in the message or args arguments.
6140 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6141 I don't understand why the check was there (and what about the
6144 * strop.c (scm_string_copy): allow shared substrings to be copied.
6146 * unif.h: corresponding change to prototypes.
6147 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6148 recognize two new optional arguments: offset and length. Allow
6149 the port argument to be an integer (file descriptor, for scsh).
6150 Include <unistd.h> for "read" prototype.
6152 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6154 * socket.c: don't include filesys.h.
6156 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6158 * Makefile.am: add AWK=@AWK@ (?)
6160 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6162 Add a rule to generate errnos.c from errnos.
6163 * error.c (scm_init_error): include errnos.c.
6164 * errnos_cnvt.awk: new file, converts the list of errno codes to
6166 * errnos_get.c: new file.
6167 * errnos.default: new file, contains errnos to try if they can't
6168 be extracted from errno.h.
6169 * configure.in: if using GCC, try and extract errno codes from
6173 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6175 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6176 * Makefile.am: Made libguile into a libtool library.
6177 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6178 Set libtool_libs to indicate that libguile is a libtool library.
6179 See guile/ChangeLog for details.
6180 * .cvsignore: ignore "*.lo", the libtool library objects.
6182 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6184 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6185 use htons in getservbyport argument.
6187 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6189 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6190 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6193 * objprop.c (scm_object_property): No need to take the CDR of the
6194 value returned by scm_object_properties, since Aug 20 change.
6196 * configure.in: When checking for struct linger, #include
6197 <sys/types.h> as well as <sys/socket.h>. I've never known
6198 <sys/types.h> to cause any portability problems, and Solaris's
6199 <sys/socket.h> needs it.
6200 * configure: Rebuilt.
6202 I think the Sun compiler has chosen a perverse way to interpret
6203 ANSI declarations combined with K&R definitions. We'll
6204 appease it a little bit. But when it invades France, we fight.
6205 * print.c (scm_iprlist): Change 'tlr' argument to an int.
6206 * print.h (scm_iprlist): Here too.
6207 * numbers.c (scm_divbigdig): Change definition to match
6208 declaration in numbers.h.
6209 * unif.c (scm_makflo): Change definition to match declaration in
6212 * init.c (scm_boot_guile): Don't return the value of
6213 scm_boot_guile_1. This function doesn't return a value;
6214 scm_boot_guile_1 doesn't return a value (or return at all).
6216 * eval.c (unmemocopy): Add a semicolon to appease the Sun
6219 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
6220 compile. I have a feeling this function is a bad idea anyway ---
6221 one should always test for features, not systems.
6223 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
6224 semicolons. Only pure luck kept this from being noticed earlier.
6226 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
6228 * socket.c (scm_recvfrom): Added missing semicolon.
6230 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6232 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
6233 the buffer and start and end positions for scsh networking
6236 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
6238 * configure.in: Revert previous change to this file; the problem
6239 is due to transient automake weirdness.
6240 * configure: Rebuilt.
6242 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
6243 PLUGIN/guile.libs. configure generates the latter from the former.
6244 * Makefile.in: Rebuilt.
6246 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
6247 need this if we install scripts, like guile-snarf.
6248 * configure: Rebuilt.
6250 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6252 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
6254 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
6256 * socket.c (scm_addr_vector): fix faulty scm_listify.
6258 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
6260 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
6261 style block comment is no longer considered an error.
6263 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
6265 * PLUGIN/guile.libs.in: New file.
6266 * PLUGIN/guile.libs: Removed from repository.
6267 * configure.in: Create PLUGIN/guile.libs from
6268 PLUGIN/guile.libs.in. This is for including additonal libraries
6269 needed for dynamic linking.
6270 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
6271 instead of PLUGIN/guile.libs.
6273 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
6275 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
6277 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
6278 occurrences of the given element from the list, not just the
6279 first. This is how the Emacs Lisp functions behave, how the
6280 analogous Common Lisp functions behave, and (I believe) how the
6281 older Maclisp functions worked. I realize that this change may
6282 break code, but it seemed better to break it before the Guile
6285 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
6286 Their prototypes were already present in gc.h, but they weren't
6288 (scm_init_storage): Initialize scm_protects.
6289 * root.c (scm_protects): New element of scm_sys_protects.
6291 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
6293 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6295 * libguile.h: Added #include "libguile/net_db.h".
6297 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
6298 30 change. That file is only meant for communication between the
6299 configuration process and load.c. If code linked against libguile
6300 wants to get at the paths mentioned in libpath.h, it can call
6301 functions declared in load.h.
6303 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6305 * libguile.h: Removed #include "libguile/fdsocket.h"
6307 * net_db.c: Added #include <sys/socket.h>.
6309 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
6311 * filesys.c (scm_input_waiting_p): use select in preference to
6312 FIONREAD, since the latter doesn't detect EOF.
6313 Throw error if neither select nor FIONREAD available.
6315 * socket.c (scm_connect): take a port, not a fd object.
6316 (scm_fill_sockaddr): throw an error if fam is not recognised.
6317 (scm_bind): use scm_fill_sockaddr.
6318 (scm_listen): take a port, not a fd object.
6319 (scm_accept): take and return a port. return #f in the car if
6320 address can't be got
6321 (scm_sock_fd_to_port): new procedure.
6322 (scm_socket): use scm_sock_fd_to_port.
6323 (scm_addr_vector): throw error if unrecognised address type.
6324 take an extra argument with the calling procedure name.
6325 (scm_getsockname): take a port. return #f if address can't be got.
6326 (scm_getpeername): take a port. return #f if address can't be got.
6327 (scm_recvfrom): take a port. return #f for address component if can't
6329 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6330 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6332 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6334 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6335 use separate data pointers, to allow them to be designed
6336 independently and reused.
6337 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6338 Renamed from catch_body, catch_handler, and uncaught_throw; made
6340 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6342 (scm_catch): Use the above.
6343 (scm_throw): Don't bother printing a message for an uncaught
6344 throw; we establish a default handler in init.
6345 * throw.h (scm_internal_catch): Prototype updated.
6346 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6348 (struct scm_body_thunk_data): New structure, used as data
6349 argument to scm_body_thunk.
6350 * init.c (struct main_func_closure): New structure, packaging up
6351 the data to pass to the user's main function.
6352 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6353 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6354 scm_internal_catch to establish a catch-all handler, using
6355 scm_handle_by_message. This replaces the special-case code in
6357 (invoke_main_func): Body function for scm_internal_catch; invoke
6358 the user's main function, using the main_func_closure pointer to
6359 decide what to pass it.
6360 * root.c (struct cwdr_body_data): Remove handler_proc member.
6361 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6362 (cwdr_handler): Removed.
6364 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6366 * socket.h (SCM_P): update bind prototype.
6367 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6368 include "feature.h".
6369 (scm_socket): return a port, not a file descriptor object.
6370 include "fports.h" and <unistd.h>
6371 (scm_bind): take a port, not a file descriptor object.
6372 take an extra argument for address args.
6374 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6375 INADDR_NONE, INADDR_LOOPBACK.
6377 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6379 * init.c: include net_db.h and not fdsocket.h.
6380 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6382 * Makefile.am: corresponding changes.
6383 * socket.h: renamed from fdsocket.h, fix names.
6384 * net_db.h: renamed from socket.h, fix names.
6385 * socket.c: renamed from fdsocket.c.
6386 remove _sys from procedure names.
6387 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6388 add "socket" to features list.
6389 * net_db.c: renamed from socket.c.
6390 remove _sys from procedure names.
6391 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6392 add "net-db" to features list.
6393 include "net_db.h". don't include <sys/socket.h> or
6396 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6398 * tags.h (scm_tags): Removed comma at end of last enumerator.
6400 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6402 Don't use GCC extensions to allocate space for debugging frames.
6403 (Here he goes again! Why do we put up with this?!)
6404 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6405 an scm_debug_info structure, not an in-line array of them. Add
6406 'info' member, to say how many vect elements we've used, for eval
6408 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6409 a new variable debug_info_end to mark the end of vect, instead of
6410 the address of the 'info' pointer itself.
6411 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6412 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6413 (SCM_APPLY): Explicitly allocate space for debug.vect.
6414 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6415 * stacks.c: Adjusted for new debug frame structure.
6416 (RELOC_INFO, RELOC_FRAME): New macros.
6417 (stack_depth, read_frames): Use them, and new scm_debug_frame
6418 element 'info', instead of magically knowing that eval frames have
6419 an info pointer sitting after vect.
6420 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6422 (scm_init_stacks): Formatting tweaks.
6424 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6426 Give GCC more control flow information, so it can be sure that
6427 variables aren't used uninitialized.
6428 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6429 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6430 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6431 scm_misc_error): Tell GCC that these functions never return.
6432 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6433 out the field type, call abort if SCM_ASSERT returns, to placate
6435 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6436 scm_wta ever returns. We can't handle this case anyway, and this
6437 gives the optimizer more information.
6438 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6439 scm_wta ever returns.
6441 In some cases, the code is fine, but GCC isn't smart enough to
6442 figure that out; this usually happens when one variable is only
6443 initialized and used when a particular condition holds true, and
6444 we know that condition will never change within a given invocation
6445 of the function. In this case, we simply initialize the variables
6446 to placate the compiler, hopefully to a value which will cause a
6447 crash if it is ever actually used.
6448 * print.c (scm_iprin1): Initialize mw_pos.
6449 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6450 * throw.c (scm_ithrow): Initialize dynpair.
6451 * unif.c (scm_uniform_vector_ref): Initialize cra.
6452 * struct.c (init_struct): Initialize prot.
6453 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6455 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6456 if EXPR contains no expressions.
6458 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6460 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6461 cause an infinite loop (???). So much for the algebraic
6462 equivalency of variable-sized arrays and alloca...
6464 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6466 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6467 a SCM boolean, not a C boolean.
6469 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6471 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6472 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6473 rules for raising scm_mtrigger. Previously, unfortunate but not
6474 unlikely circumstances could result in almost constant invokation
6475 of the gc. Now, this situations should be less likely, but they
6476 are not prevented completely.
6478 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6480 * numbers.c (scm_fuck): Procedure removed; looks like old test
6482 * numbers.h: Prototype removed.
6484 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6486 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6487 array to a pointer, to match my Nov 21 change in eval.c.
6489 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6491 * libguile.h: Added #include "libguile/backtrace.h", #include
6492 "libguile/stacks.h".
6494 * strings.c (scm_string scm_make_string scm_string_ref
6495 scm_string_set_x scm_string_equal_p scm_string_append):
6496 Bugfix according to scm patch from Aubrey Jaffer:
6497 Corrected long-standing
6498 (not (eqv? (integer->char 128)
6499 (string-ref (make-string 1 (integer->char 128)) 0)))
6500 bug found by John Kozak <jk@noontide.demon.co.uk>.
6502 * strports.c, strports.h: Make scm_eval_0str return the value of
6503 the last expression evaluated (previously, it returned void).
6505 * strports.c, strports.h: New function: scm_read_0str. Does what
6508 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6510 * simpos.c (scm_getenv): return #f if string can't be found in the
6511 environment instead of throwing an exception, for compatibility
6512 with numerous other systems.
6514 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6516 * Makefile.am (.c.x): Use guile-snarf.
6517 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6519 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6521 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6523 * backtrace.c (scm_display_error_message): Made non-static, and
6524 renamed from display_error_message.
6525 * backtrace.h (scm_display_error_message): Added extern decl.
6526 * throw.c (uncaught_throw): Use it to display the error message.
6528 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6530 * inet_aton.c: Use #if 0, not #ifdef 0.
6532 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6534 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6535 to convert the returned value.
6536 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6537 the offset argument.
6539 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6541 Add new interface to catch/throw, usable from C as well as
6543 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6544 (scm_internal_catch): New function, replaces...
6545 (scm_catch_apply): Deleted.
6546 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6547 mechanism which is a bit more code, but can be used nicely from C
6548 and implement the Scheme semantics as well.
6549 (scm_internal_catch): This is the replacement; it's named after
6550 the analogous function in Emacs.
6551 (scm_catch): Reimplemented in terms of the above.
6552 (struct catch_body_data, catch_body, catch_handler): New
6553 functions, used by scm_catch.
6554 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6555 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6556 support for new cwdr.
6558 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6561 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6563 * acconfig.h: Added DYNAMIC_LINKING symbol.
6564 * configure.in: Add option and checks for dynamic linking.
6565 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6566 dynl.h: New files for dynamic linking support.
6567 * Makefile.am (libguile_a_SOURCES):
6569 (modinclude_HEADERS): Added "dynl.h".
6570 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6572 * init.c (scm_boot_guile_1): Call
6573 scm_init_dynamic_linking to initialize dynamic linking support.
6575 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6577 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6578 (as we Schemers say). It needs to be global, so that I can tweak
6579 it for the proper operation of unexec.
6580 (scm_boot_guile_1_live): New variable, see above.
6582 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6584 * guile-snarf.sh: Removed.
6585 * PLUGIN/guile.libs: Added dependency for -lm.
6586 * acinclude.m4: Renamed from aclocal.m4.
6587 * PLUGIN/greet: Removed.
6588 * Makefile.am, aclocal.m4: New files.
6589 * configure.in: Updated for Automake.
6591 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6593 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6594 and not top_level_lookup_thunk_var.
6596 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6598 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6600 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6602 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6603 Scheme function, instead of syntax. Single argument is now a
6606 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6608 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6609 scm_ra_divide): Properly terminate statements passed as arguments
6610 to IVDEP macros. (Thanks to Bernard Urban.)
6612 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6613 with non-constant sizes. (Thanks to Bernard Urban.)
6615 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6617 It's an "eval closure", not an "eval thunk." A thunk is a
6618 function of no arguments.
6619 * root.h (struct scm_root_state): Renamed
6620 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6621 (scm_top_level_lookup_closure_var): Renamed from
6622 scm_top_level_lookup_thunk_var.
6623 * root.c (mark_root): Uses changed.
6624 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6625 * init.c (scm_start_stack): Uses changed.
6626 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6627 Change scheme-visible name to *top-level-lookup-closure* from
6628 *top-level-lookup-thunk*.
6630 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6632 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6633 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6635 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6637 * gc.c (struct scm_heap_seg_data): Doc fixes.
6639 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6640 sweeping. Then, prepend each segment's free cells to its
6641 freelist, rather than wiping out the old value. (Thanks to Marius
6644 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6645 scm_check_freelist, scm_debug_newcell): New functions and
6646 variables, for debugging freelist problems.
6647 * pairs.h (SCM_NEWCELL): New debugging version added.
6648 * gc.h (scm_debug_newcell): Added extern declaration, used by
6649 debugging version of SCM_NEWCELL.
6651 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6653 On some systems <libc.h> conflicts with <unistd.h>, and should not
6654 be #included at all.
6655 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6656 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6657 * configure.in: Call it.
6658 * posix.c, filesys.c: Use its results to decide whether or not to
6660 * configure, scmconfig.h.in: Rebuilt with autoconf and
6663 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6665 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6666 pointer to the stdio stream before calling scm_setbuf0, so the
6667 latter will be able to retrieve it. I'm surprised this didn't
6668 segfault earlier. (Thanks to Christopher Lee.)
6670 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6672 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6675 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6677 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6678 number of stack narrowing specifier pairs. The first specifier in
6679 a pair controls inner border, the second the outer border. A
6680 number means cut that number of frames, a procedure object means
6681 cut until that object is found in operator position in a frame.
6683 * root.c (cwdr): Bugfix.
6685 * read.c: Recording of positions disabled by default.
6687 * procs.c (scm_closure_p): New function.
6689 * posix.c (scm_tmpnam): New function.
6691 * load.c: Added #include "throw.h".
6692 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6695 * load.c, load.h (scm_read_and_eval_x): New function.
6697 * eval.c: Renamed debug option "deval" to "debug".
6699 (scm_eval_x): `eval!' is no longer accessible from the scheme
6700 level. Motivation: We can't allow operations which introduce
6701 glocs into the scheme level. Guile's type system can't handle
6702 these as data. Use `eval' or `read-and-eval!' as replacement.
6704 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6705 SCM_CONSP since this is a macro!; Set vframe.prev to
6706 scm_last_debug_frame instead of 0. In this way we can look
6707 "above" the virtual start stack frame if we wish.
6708 (scm_debug_hang): New function: Useful for debugging Guile in
6709 certain tricky situations. Will probably be removed later...
6711 * debug.h: Changed semantics of debug option "backtrace". This
6712 option now only indicates whether we want automatic backtrace at
6715 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6717 * ports.c: #include "filesys.h"
6718 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6720 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6721 Motivation: This is system specific code which is related to file
6722 I/O. It also may use select. Added code by Gary Houston to
6723 detect presence of character in stdio buffers.
6725 * libguile.h: #include "libguile/libpath.h"
6727 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6728 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6729 SCM_SITE_DIR; Install libpath.h among the other include files.
6731 * load.c, load.h (scm_sys_package_data_dir): New function.
6733 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6735 * stacks.h: Bugfix: Don't use tail-array length field as stack
6736 length field! This screwed GC.
6738 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6740 * _scm.h: Added #ifndef around definition of macros min and max.
6742 * __scm.h: Added hooks for threads to plugin to in ints protection
6743 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6744 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6745 the main code in these macros duplicated and spread over multiple
6746 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6747 SCM_THREAD_SWITCHING_CODE.
6749 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6751 * snarf.h: New file.
6752 * guile-snarf.sh: New file.
6753 * Makefile.in (inner_h_files): Added snarf.h
6754 (ancillary, install, uninstall, distclean): Added actions for
6756 (.c.x): Use guile-snarf.
6757 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6758 (gen_c_files): Note that these depend on guile-snarf.
6759 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6760 now in "snarf.h". Added #include "snarf.h" to get them.
6761 * libguile.h: Added #include "snarf.h".
6762 (Patches applied and tweaked by Jim Blandy.)
6764 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6766 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6767 standards suggest against providing prototypes for system
6768 functions. Thanks to Greg Troxel.
6770 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6772 * strports.c (scm_eval_0str): New function.
6773 #include "read.h", to get prototype for scm_read.
6774 * Makefile.in (strports.o): Update dependencies.
6775 * strports.h: New prototype.
6777 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6778 scheme name from "int?" to "integer?". It seems to do the job.
6779 * numbers.h: Rename prototype too.
6780 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6783 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6784 scm_num_eq_p): Rename these according to R4RS conventions: call
6785 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6786 to making libguile R4RS compliant without ice-9...
6788 * load.c (scm_sys_search_load_path): Search for files under all
6789 extensions listed in the %load-extensions variable. If FILENAME
6790 is absolute, return it unchanged, without searching the load path.
6791 (scm_loc_load_extensions): New variable, pointing to
6792 %load-extensions' value cell.
6793 (scm_init_load): Initialize it, and the value it points to.
6794 (scm_primitive_load_path): Improve error reporting.
6796 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6797 of new Scheme variable %load-hook.
6798 (scm_primitive_load): Apply %load-hook to filename.
6800 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6802 * configure.in: add tests for figuring out whether buffered data
6803 is available in a FILE structure, which is needed by char-ready.
6805 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6808 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6809 exceptions using misc_error instead of syserror. It seems a bit
6810 odd to throw an exception if a string can't be found in the
6811 environment, but it's consistent with open-file, stat etc.
6812 (simpos.h): remove sys_ from getenv.
6814 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6815 occurs, throw an error instead of returning errno. Return value
6817 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6819 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6821 * filesys.c (scm_stat2scm): derive file type and permissions from
6822 the stat mode and append them to the returned vector.
6823 There isn't much overhead in doing this and it avoids the need to
6824 work with S_IRUSR et al. in Scheme.
6825 Define symbols scm_sym_regular etc.
6826 (scm_init_filesys): don't intern S_IRUSR etc.
6828 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6829 and s_primitive_load_path.
6831 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6833 * error.h: don't declare error symbols. prototype for scm_misc_error.
6835 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6838 * error.c: use SCM_SYMBOL to set up error keys.
6839 scm_misc_error: new procedure.
6841 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6843 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6844 between `#!' and `!#' is ignored.
6845 (skip_scsh_block_comment): New function.
6847 * feature.c (scm_set_program_arguments): New argument, FIRST.
6848 * feature.h: Update prototype.
6849 * init.c (scm_boot_guile_1): Pass new argument to
6850 scm_set_program_arguments.
6852 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6854 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6855 (scm_boot_guile): Call scm_set_program_arguments here, later than
6856 the old initialization.
6858 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6859 initialization procedure.
6860 - Delete in, out, err arguments; there are other perfectly good
6861 ways to override these when desired.
6862 - Delete result argument; this function shouldn't ever return.
6863 - Rename init_func argument to main_func, for less confusion.
6864 - Delete boot_cmd argument; main_func is more general.
6865 -Add 'closure' argument, to help people pass data to main_func
6866 without resorting to global variables.
6867 - Abort if reentered; don't bother returning an error code.
6868 - Call scm_init_standard_ports to set up the default/current
6869 standard ports; no need to pass them to scm_start_stack.
6870 - Remove code to evaluate the boot_cmd, and start the repl; let
6871 the user do something like that in main_func if they want.
6872 - Remove code to package up a return value; main_func can do any
6874 - Call exit (0), instead of returning.
6875 (scm_start_stack): Don't initialize the I/O ports here; that's
6876 weird. Delete in, out, err arguments. Move guts to
6877 scm_init_standard_ports, scm_stdio_to_port.
6878 (scm_init_standard_ports): New function, to set up current and
6879 default standard ports.
6880 (scm_start_stack, scm_restart_stack): Make these static.
6881 * init.h (scm_boot_guile): Adjust declaration.
6882 (scm_start_stack, scm_restart_stack): Remove externally
6883 visible declarations for these.
6884 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6886 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6887 written out several times in scm_start_stack.
6888 * fports.h: New declaration for the above.
6890 * feature.c (scm_set_program_arguments): New function.
6891 * feature.h: New declaration for the above.
6893 * ports.c: Formatting tweak.
6895 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6897 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6898 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6899 for obtaining the address of a car or cdr field. Motivation:
6900 &SCM_CXR make assumptions about the internal structure of the
6903 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6904 Motivation: see SCM_CXRLOC.
6906 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6907 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6908 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6909 Motivation: Safer use. Some other macros are defined in terms of
6910 these operations. If these are defined using the SCM_SETCXR
6911 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6912 to inefficiency and an <e1> with side-effects could potentially
6913 break. Also, these particular operations are heavily utilized in
6914 the garbage collector. In unoptimized code there will be a
6917 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6918 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6919 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
6920 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
6921 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
6922 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6923 vports.c: Cleaned up use of pairs: Don't make any special
6924 assumptions about the internal structure of selectors and
6925 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6926 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
6927 (Among other things, this change makes it easier to build Guile
6928 with certain compilers which have problems with casted lvalues.)
6930 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6932 * stacks.c: Improve selection of relevant stack frames when making
6933 a stack object. Introduce one level of indirection in the stack
6934 object to make it possible to "narrow" to a certain region of the
6935 stack. This facilitates making use of more clever algorithms (not
6936 implemented) for selecting relevant frames and gives a cleaner
6937 design since selection of frames can be done independently of
6938 extraction of frames from the real stack.
6939 (scm_stack_id): Also take #t as argument which means look at
6942 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
6943 Turn n_tail into an integer directly representing current number
6944 of frames in stack. Add field tail.
6946 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
6948 * debug.c (scm_make_memoized): Made it available at scheme level.
6949 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
6950 SCM_NIMP before applying heavier predicates in argument checking.
6951 (scm_local_eval): Also take memoized object as argument.
6953 * backtrace.c (scm_display_error): Just a safety measure: Stacks
6954 aren't created with zero length, but should such a strange
6955 creature suddenly turn up...
6957 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
6959 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
6960 `del', for the sake of C++ compilers. (Patch applied by JimB.)
6962 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
6964 * variable.c (scm_make_variable): Make the name hint optional, as
6966 (anonymous_variable_sym): Renamed from variable_sym. All uses
6969 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
6970 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
6971 of scm_primitive_load_path was also changed to
6972 "primitive-load-path", from "%try-load-path". Callers changed.
6973 We'd like to respect the convention that a function named
6974 "try-mumble" should behave just like the function called "mumble",
6975 but return #f instead of signalling some error.
6976 * load.h: Rename prototypes.
6978 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6980 * print.c (make_print_state, grow_print_state), print.h: Modified
6981 the print state representation: Don't use a tail array for
6982 recording of circular references. Resizing of the print state
6983 structure invalidates the print state pointer. To avoid passing
6984 around an indirect print state reference to all printing
6985 functions, we instead let the print state reference a resizable
6988 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
6990 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
6991 Don't crash when passed an improper list terminated by a
6992 non-immediate value.
6994 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
6996 Allocate data for structures on an eight-byte boundary, as
6997 required by the tagging system.
6998 * struct.c (alloc_struct): New function.
6999 (scm_make_struct, scm_make_vtable_vtable): Call it.
7000 * struct.h (scm_struct_n_extra_words): Bump to 3.
7001 (scm_struct_i_ptr): New "field".
7002 * gc.c (scm_gc_sweep): When we need to free the data, use the
7003 information stored by alloc_struct to find the beginning of the
7004 block allocated to the structure, so we can free it.
7006 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7008 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
7011 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
7012 (scm_debug_info): New member: id.
7014 * stacks.c: Stacks are now represented as structs; Stacks have an
7015 id given to them by `start-stack'.
7016 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
7018 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
7019 Changed stack representation.
7021 * debug.c (scm_procedure_name): Try procedure property `name' for
7022 compiled closures aswell.
7024 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
7026 * eval.c: scm_i_name moved to gsubr.c
7027 (scm_m_define): Record names of all kinds of procedure
7028 objects. (Earlier, only closures were recorded.)
7030 * procprop.h: Added declaration of scm_i_name.
7032 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7033 (scm_make_gsubr): Record names of compiled closures.
7035 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7037 * debug.c, debug.h: Removed obsolete code.
7039 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7040 stacks.c: Renamed regs --> scm_contregs.
7042 * print.c (scm_free_print_state): Cleanup print state before
7043 returning it to pool. It is better to do it here than in
7044 scm_prin1 since scm_prin1 is called often.
7046 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7047 s_set_source_property_x): Check that first argument is a pair or a
7050 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7051 scm_i_line, scm_i_column and scm_i_breakpoint global.
7053 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7054 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7057 * debug.h: Added debug object smob declaration and macro
7060 * configure.in: Build with backtrace.o and stacks.o if debug
7063 * Makefile.in: Added entries for new files: backtrace.c,
7064 backtrace.h, stacks.c and stacks.h.
7066 * symbols.c (scm_sym2ovcell): Fixed documentation.
7068 * _scm.h (min, max): Added.
7070 * async.c: Moved `min' macro to _scm.h.
7072 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7073 SCM_BACKTRACE_INDENT.
7075 * eval.c: Added new debug options `maxdepth' and `indent'.
7077 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
7079 * print.h: Added selector SCM_PRINT_STATE.
7081 * print.c: New functions: scm_make_print_state,
7082 scm_free_print_state.
7084 * print.h: Added declarations for scm_make_print_state,
7085 scm_free_print_state.
7087 * debug.c (scm_m_start_stack): New acro.
7089 * debug.h: Small cleanup.
7091 * init.c (scm_boot_guile_1): Moved scm_init_debug below
7094 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

7114 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
7115 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
7116 declare functions with prototypes. (Patch thanks to Marius
7119 More prototype-related changes from Marius Vollmer:
7120 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7121 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7122 * ports.h (ptobfuns): Added prototypes. This means some casting in
7124 * fports.c: Added casts for initializations, since the functions
7125 are defined to take FILE * as their stream argument, not SCM.
7126 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7127 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7128 to `char *str_data' to conform to prototype.
7130 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7132 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7134 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7136 * stime.c, stime.h: use SCM_P method.
7138 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7140 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7141 be given at least two arguments. Insist that lst's last element
7142 be a list, but don't make any requirements of its predecessors.
7144 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7146 * eval.c (scm_nconc2last): Revert last change; there seems to be
7147 other stuff going on here.
7149 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7151 * eval.c (scm_nconc2last): Make sure that each element of lst
7152 (which is a list of argument lists, except for the tail) is a
7153 proper list, i.e., finite and terminated by '().
7155 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7157 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7160 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7161 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7164 * vectors.c (scm_make_vector): Fill vectors with the undefined
7165 value, to help make Guile Scheme code more portable to other
7168 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7169 * symbols.h, tags.h: Doc fixes.
7171 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7173 * async.c (scm_take_signal): Doc fixes.
7175 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7177 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7178 want to subtract it from the modulus; we just want to leave it
7181 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7183 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7186 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7188 * throw.c (scm_catch_apply): Finished implementation of
7191 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7193 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7195 (scm_init_filesys): set "i/o-extensions" feature.
7198 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7200 * Makefile.in (root.o): Correct dependencies.
7202 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7204 * Makefile.in: Added dependency entry for root.o.
7206 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
7207 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
7209 * init.c (scm_start_stack): Set initial root continuation number
7212 * procs.c: New function: scm_thunk_p.
7214 * procs.h: Added declarations of scm_thunk_p.
7216 * root.c: Renamed `call-with-new-root' -->
7217 `call-with-dynamic-root'.
7218 (cwdr): Removed allocation of new root state. This should be done
7219 separately by use of scm_make_root.
7220 (scm_apply_with_dynamic_root): New function: Does what it
7221 sounds like. Needed when spawning threads.
7223 * root.h: Added member last_debug_frame to root state.
7224 Added #include "libguile/debug.h"
7226 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
7227 arguments. The motivation is that code in root.c needs catch
7228 functionality, and we want to avoid code duplication.
7229 New functions: scm_catch, scm_lazy_catch. These are wrappers for
7230 scm_catch_apply. scm_lazy_catch is intended to introduce catch
7231 handlers that run without popping the stack into the dynwind
7234 * throw.h: Added prototypes for scm_catch_apply and
7237 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7239 * root.h (scm_root, scm_set_root): Decouple thread support details
7240 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
7241 SCM_SET_THREAD_LOCAL_DATA.
7243 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
7244 and tortoise scanning loop.
7246 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
7248 * Makefile.in: Rebuild dependencies.
7250 * libguile.h: #include "libguile/print.h" before "smob.h", since
7251 the latter uses the print_state structure.
7253 * throw.c (scm_ithrow): Use the correct variable when checking to
7254 see if a given element of scm_dynwinds is a valid catch.
7256 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
7257 structure, abort; don't just silently ignore the garbage.
7259 * _scm.h: #include "print.h" here, since it seems to be used just
7261 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
7262 strports.c, unif.h: Don't #include "print.h".
7264 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7266 * feature.h (scm_loc_features): Removed external declaration.
7267 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
7269 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7271 * feature.c (scm_init_feature): Added threads feature (needs to be
7272 initialized here, since features doesn't exist when
7273 scm_init_threads is called).
7275 * libguile.h: Added #include "libguile/../threads/threads.h".
7276 (This is a kludge to get thread support working. This should be
7279 * configure.in, acconfig.h: Added flags for thread support.
7281 * scmsigs.c: Define `signal' to be `pthread_signal' if using
7284 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
7285 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
7288 * _scm.h: Added conditional #include "threads.h"
7290 * __scm.h (SCM_ASYNC_TICK): Added call to macro
7291 SCM_THREADS_SWITCHING_CODE.
7293 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
7294 allocate the basic dynamic root object.
7295 (scm_boot_guile): Added call to scm_init_root.
7297 * root.c, root.h: Added root smob.
7298 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
7299 functions: Implements dynamic roots mostly according to spec in
7300 SCM manual. Main difference is that the second argument is a
7301 throw handler rather than an error "thunk".
7303 * root.h: Added declaration of scm_init_root.
7305 * root.c: Added #include "genio.h", #include "smob.h", #include
7306 "pairs.h", #include "throw.h", #include "dynwind.h", #include
7308 (scm_init_root): Added #include "root.x".
7310 * throw.c: Added #include "stackchk.h"
7311 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
7312 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
7313 can be used in scm_call_with_new_root; Added reenabling of stack
7314 checking when catching a throw.
7316 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
7318 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
7320 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
7321 element is not found, as per R4RS.
7323 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7325 * list.c: Doc fixes throughout.
7327 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7329 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7330 declare the char * to be const. Avoids a warning in rgx.c.
7332 * ports.h: spelling fix.
7334 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7337 * load.c (scm_sys_try_load_path): throw an error if file not found
7338 (like it says it in NEWS).
7340 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7342 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7343 PROPS slot to '(), not #f; it's an empty alist.
7345 * throw.h, throw.c: Use SCM_P instead of #if hair.
7347 Remove special support for uncaught throws; see throw.c for
7349 * throw.c (uncaught_throw): New function.
7350 (scm_ithrow): Call uncaught_throw if we don't find a throw
7351 target; don't mess with scm_bad_throw_vcell.
7352 (scm_bad_throw_vcell): Variable deleted.
7353 (scm_init_throw): Don't initialize it.
7355 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7358 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7360 * numbers.c (scm_istr2int): If the number is short (as most
7361 numbers are), just call scm_small_istr2int to deal with it.
7362 (scm_small_istr2int): New function, created by un-#ifdefing the
7363 non-bignum version of scm_istr2int and renaming it.
7365 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7367 * load.c (scm_sys_try_load): don't check whether value returned
7368 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7369 Change the Scheme name from %try-load to primitive-load.
7371 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7372 Can avoid passing a message, allowing it to be derived in the
7373 error handler (e.g., if we want to throw to the key both from
7376 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7378 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7379 references now have a new appearance which is more compact and
7380 also gives a clue about what the target of the reference is.
7381 By setting parameters in the print state, more fancy printing can
7382 be achieved. This is used by the (not yet commited) backtrace
7385 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7387 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7390 * print.c: Added #include "struct.h". Removed function
7393 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7394 scm_iprin1. Removed prototype for scm_prlist.
7396 * arbiters.c (prinarb),
7397 async.c (print_async),
7398 debug.c (prindebugobj, prinmemoized),
7399 eval.c (prinprom, prinmacro),
7400 filesys.c (scm_fd_print, scm_dir_print),
7402 mallocs.c (prinmalloc),
7403 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7404 smob.h (scm_smobfuns),
7405 srcprop.c (prinsrcprops),
7407 unif.c, unif.h (scm_raprin1, rapr1),
7408 variable.c (prin_var): Changed argument `int writing' to
7409 `scm_print_state *pstate'.
7411 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7412 that it will be called before scm_init_print.
7414 * print.c (scm_prin1): Print states are now allocated when calling
7415 scm_prin1 and then passed around to all printing functions as an
7416 argument. A cache `print_state_pool' enables reuse of print
7418 (scm_make_print_state): New function.
7419 (scm_iprin1): Adaption to print states.
7420 (scm_iprlist): An initial "hare and tortoise" scan brings down
7421 time complexity to O (depth * N). (Better time complexity will be
7422 achieved when the printing code is completely rewritten.)
7424 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7426 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7427 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7428 it gets done whether or not the cache variable has a value.
7430 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7432 Distinguish #f and ().
7433 * __scm.h: #undef SICP.
7434 * pairs.h (SCM_EOL): Delete this definition, equating it with
7436 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7437 the value it used to have. Doc fixes, too.
7439 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7441 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7442 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7443 Lord's implementation of structs, allowing for tail arrays as
7444 described in the manual. Also fixed some bugs. (Both the interface
7445 and the implementation should be improved.)
7447 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7449 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7450 People who whish to see the source can do `(print-enable 'source)'.
7451 Removed #ifdef DEBUG_EXTENSIONS.
7453 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7455 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7456 integer (assuming for now accepting an integer is a good thing).
7458 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7459 %S will be used instead for write'ing arguments.
7461 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7462 asserts. fix a few other asserts.
7463 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7464 scm_uniform_vector_ref, scm_array_set_x,
7465 scm_dimensions_to_unform_array): change args in
7466 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7467 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7468 scm_substring_fill_x): likewise.
7469 gsubr.c (scm_gsubr_apply): likewise.
7470 eval.c (SCM_APPLY): likewise.
7472 * eval.c (4 places): replace scm_everr with lgh_error or
7475 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7476 scm_memory_error): new procedures.
7477 scm_everr: deleted. can use scm_wta, dropping first two args.
7478 scm_error: convert NULL subr to SCM_BOOL_F.
7480 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7483 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7486 * error.c, error.h: new error keys: scm_arg_type_key,
7487 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7489 scm_wta: reimplement using lgh_error instead of scm_everr.
7491 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7493 * gdbint.c: scm_lread now has one more argument.
7495 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7496 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7497 loading source from non-file ports, which, e. g., happens when
7498 using the Emacs interface).
7500 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7503 * read.c: Added code for recording of positions of source code
7504 expressions; New functions: recsexpr, scm_lreadrecparen;
7505 _scm_make_srcprops --> scm_make_srcprops
7506 (scm_flush_ws): Removed updating of positions counters. This work
7507 is already done by scm_gen_getc
7509 * read.h: Added prototype for scm_lreadrecparen
7511 * print.c: Added #include "alist.h"
7513 * eval.c: Added #include "hash.h"
7515 * eq.c: Added #include "ramap.h"
7517 * options.c: Documentation fixes.
7519 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7520 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7521 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7522 --> scm_make_srcprops
7524 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7525 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7526 function calls in the definition of the whash access macros.
7528 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7530 * init.c (scm_boot_guile): Add level of indirection to
7531 scm_boot_guile_1() to ensure that stack base pointer is properly
7532 initialized. There was no guarantee that variable i was the
7533 highest/lowest variable on stack (i.e. the call frame of
7534 scm_boot_guile was not completely protected from gc).
7536 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7538 * ports.h (scm_port_table): put back file_name, it will be used to
7539 support debugging. Undo related changes in fports.c, ioext.c,
7542 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7544 * ports.h (scm_port_table): remove file_name member for now, it seems
7546 * fports.c (scm_open_file): don't set file_name in PTAB.
7547 (prinfport): don't use file_name in PTAB.
7548 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7549 * ports.c (scm_add_to_port_table): don't intialize file_name.
7550 (scm_port_file_name): remove for now.
7551 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7553 * fports.h (scm_mkfile): prototype deleted.
7554 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7556 * debug.c, unif.c: use scm_out_of_range instead of
7557 wta for range errors (ASSERT still needs work).
7559 * error.c, error.h (scm_out_of_range): new procedure.
7561 * error.c, error.h (scm_out_of_range_key): new key.
7563 * posix.c (scm_sync): #else was missing.
7565 * error.c, error.h: append _key to names scm_num_overflow and
7568 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7569 of consing an empty list.
7570 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7571 of macros, saves code and string space.
7572 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7573 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7574 lower case. Rename scm_syserror_m to scm_syserror_msg.
7575 error.h: prototypes for new procedures.
7577 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7579 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7581 * error.c, error.h: setup scm_num_overflow key.
7583 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7584 Remove definition of SCM_OVSCM_FLOW.
7586 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7588 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7589 explicit message and args.
7591 * error.c, error.h, __scm.h: change system_error_sym to
7594 * error.c (system_error_sym): remove leading %% from the Scheme name
7597 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7599 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7601 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7602 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7603 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7604 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7605 renamed. (These were introduced by unsupervised name
7608 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7610 * print.c: Added code for detection of circular references during
7611 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7612 a hook for printing of closures (accessible via print options).
7613 This leads to a split of calls to scm_iprin1 into two classes:
7614 elementary print operations (e. g. the code which prints a smob)
7615 still use scm_iprin1 while top level calls (like scm_display) use
7616 scm_prin1. scm_prin1 begins by clearing the data structure used
7617 to record reference information.
7619 * print.h: Added declarations of scm_prin1 and scm_prlist.
7621 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7623 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7625 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7627 * error.c (err_head): scm_iprin1 --> scm_prin1
7629 * debug.c: Adjusted header comment.
7633 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7635 * strerror.c: Doc fix.
7637 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7639 * gdbint.c (gdb_read): Now possible to run during GC.
7640 (unmark_port, remark_port): New functions.
7642 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7644 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7645 of allocating a new string object. Also, increase size by
7646 the factor 2 instead of 1.5.
7648 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7650 * __scm.h (SCM_P): Corrected to run under traditional C.
7652 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7655 * async.c: Calls to scm_sysintern corrected.
7657 * async.h (scm_async_clock): Redundant declaration removed.
7659 * continuations.c (scm_dynthrow): Redundant declaration removed.
7661 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7662 Definition typos corrected.
7664 * debug.h: Missing declarations of functions in debug.c added
7667 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7668 Missing declarations to functions in eval.c added.
7670 * filesys.c: Possibly uninitialized variable rv.
7672 * gc.h (scm_object_addr, scm_unhash_name): Missing
7673 declarations of functions defined in gc.c added.
7675 * genio.c: Possible typos str_data -> wstr_data. ???
7677 * genio.c: Possibly unintended shadowing of local variable
7678 `int c' (gotos out of scope of inner `c'). ???
7680 * init.c: Uninitialized `SCM last' may be used.
7682 * ioext.h: (scm_sys_isatty_p): Typo.
7684 * list.h (scm_list_head): Missing prototype for function in
7687 * numbers.c (scm_two_doubles): Changed from extern to static
7688 (is used only within numbers.c).
7690 * numbers.h: Repeated declarations removed.
7692 * ports.h (scm_close_all_ports_except): Declaration for the
7693 function defined in ports.c added.
7695 * posix.h: Missing declarations added.
7697 * procs.h (scm_make_subr_opt): Missing declaration added.
7699 * socket.h (scm_sys_gethost): Missing declaration added.
7701 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7703 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7704 Missing declarations added.
7706 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7708 * struct.c: Uninitialized variable `SCM answer' may be used.
7710 * unif.c (l2ra): Declaration prototype.
7712 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7713 defined in ramap.c).
7715 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7716 Redundant declarations removed (they are in ramap.h).
7718 * variable.h (scm_make_udvariable,
7719 scm_make_undefined_variable): Declaration corrected to
7720 correspond variable.c.
7722 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7723 Missing declarations added.
7725 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7727 * Makefile.in (distclean): Don't forget to delete fd.h.
7729 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7731 * fd.h.in, tags.h: Trivial cleanups.
7733 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7734 marksweep.h just declared functions from gc.c.
7735 * gc.h, libguile.h: Don't #include "marksweep.h".
7736 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7737 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7738 dependencies updated.
7740 * libguile.h: Don't #include "files.h"; it's been deleted.
7742 * files.c (scm_sys_delete_file): Moved to filesys.c.
7743 File is now empty; deleted.
7745 * filesys.c: scm_sys_delete_file is now here. Remove
7746 #if's; they seem to rely on remnants of an old portability
7747 regimen. If the problems come up again, solve them properly,
7748 using autoconf. Specifically: Don't test M_SYSV, and #define
7749 remove to be unlink if it's #defined; don't use remove just
7750 because HAVE_STDC_HEADERS is #defined.
7751 * filesys.h: Add declarations for scm_sys_delete_file.
7752 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7753 files.o, files.h, files.c, and files.x.
7754 * init.c: Don't #include "files.h", and don't call scm_init_files.
7756 Use SCM_P instead of PROTO; the latter intrudes on the user's
7758 * params.h: Deleted; definition of SCM_P moved to...
7759 * __scm.h: ... here, where it replaces PROTO macro.
7760 * libguile.h, smob.h: Don't #include "params.h".
7761 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7762 smob.h: Fix prototypes accordingly.
7763 * Makefile.in: Update dependencies.
7764 (inner_h_files): Remove params.h.
7766 * gc.c: #include "gc.h"; every module should include its header,
7767 to let the compiler cross-check the declarations against the
7770 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7771 simpos.h: #include "libguile/__scm.h".
7773 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7775 * init.c: Don't forget to #include smob.h and init.h.
7776 * Makefile.in: Dependencies updated.
7778 * smob.h: Use PROTO instead of #if __STDC__.
7780 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7782 * __scm.h: Doc fixes.
7784 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7785 <angles>; this allows `make depends' to work properly.
7787 * libguile.h: #include smob.h and pairs.h before the others; they
7788 define typedefs used by other headers.
7790 C files should #include only the header files they need, not
7791 libguile.h (which #includes all the header files); the pointless
7792 recompilation was wasting my time.
7793 * Makefile.in (all .o dependency lists): Regenerated.
7794 * libguile.h: Don't try to get a definition for size_t here...
7795 * __scm.h: Do it here.
7796 * _scm.h: Since this is the internal libguile header, put things
7797 here that all (or a majority) of the libguile files will want.
7798 Don't #include <libguile.h> here; that generates dependencies on
7799 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7800 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
7801 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and
7803 * alist.c: Get "eq.h", "list.h", "alist.h".
7804 * append.c: Get "append.h", "list.h".
7805 * arbiters.c: Get "arbiters.h", "smob.h".
7806 * async.c: Get "async.h", "smob.h", "throw.h", "eval.h".
7807 * boolean.c: Get "boolean.h".
7808 * chars.c: Get "chars.h".
7809 * continuations.c: Get "continuations.h", "dynwind.h", "debug.h",
7811 * debug.c: Get "debug.h", "feature.h", "read.h", "strports.h",
7812 "continuations.h", "alist.h", "srcprop.h", "procprop.h", "smob.h",
7813 "genio.h", "throw.h", "eval.h".
7814 * dynwind.c: Get "dynwind.h", "alist.h", "eval.h".
7815 * eq.c: Get "eq.h", "unif.h", "smob.h", "strorder.h",
7817 * error.c: Get "error.h", "throw.h", "genio.h", "pairs.h".
7818 * eval.c: Get "eval.h", "stackchk.h", "srcprop.h", "debug.h",
7819 "hashtab.h", "procprop.h", "markers.h", "smob.h", "throw.h",
7820 "continuations.h", "eq.h", "sequences.h", "alist.h", "append.h",
7822 * fdsocket.c: Get "fdsocket.h", "unif.h", "filesys.h".
7823 * feature.c: Get "feature.h".
7824 * files.c: Get "files.h".
7825 * filesys.c: Get "filesys.h", "smob.h", "genio.h".

7898 * weaks.c: Get "weaks.h".
7900 * stackchk.h: #include "libguile/debug.h",
7902 * print.h, read.h: #include "options.h", since everyone who uses
7903 either of these files will need that.
7905 * smob.h: #include "ports.h", "genio.h", and "print.h", since
7906 anyone who uses this file will need them to define the smob
7907 printing functions. Also, get markers.h, since people will need
7908 to #define the mark functions.
7910 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
7911 * ports.h: ... to here.
7913 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7914 don't rely on archaic C default type rules.
7916 * fports.h: #include "libguile/ports.h", since you need that in
7917 order to parse this.
7919 * genio.h: #include "libguile/print.h", because you need that to
7920 parse this; don't bother #including "ports.h", since print.h gets
7923 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7925 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7926 this; it's now a reference to an element of *scm_root.
7928 * debug.h: Don't #include "options.h"; the compiler won't be able
7929 to find that once the headers are installed; instead, #include
7930 "libguile/options.h".
7931 * gc.h: Same, with marksweep.h.
7932 * mbstrings.h: Same, with symbols.h.
7933 * scmhob.h: Same, with _scm.h.
7934 * smob.h: Same, with params.h.
7936 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
7937 C files; there's no need for this, and it forces recompilations
7940 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
7942 * error.c (scm_error): declare scm_error_callback.
7944 * error.h: prototype for scm_error_callback.
7946 * __scm.h: define lgh_error.
7947 (SCM_SYSERROR): redefine using lgh_error.
7949 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
7951 * error.c (scm_error): new procedure.
7953 * error.h: prototype for scm_error.
7955 * Makefile.in (install): install scmconfig.h from the current
7956 directory, not $(srcdir).
7958 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7960 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7961 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7962 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
7963 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,

7968 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7969 vports.h, weaks.h: #include "libguile/__scm.h", not
7970 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
7971 dependencies are within libguile properly.
7973 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7975 * Makefile.in (.c.x): Simplify; there's no need to run this rule
7976 when scmconfig.h doesn't exist.
7978 * load.c (scm_sys_try_load): Correct spelling.
7980 * feature.c (scm_loc_features): Make this static.
7982 * Makefile.in (libpath.h): Omit trailing slash from path. We
7983 shouldn't require it of users, so why put it here?
7985 Move code to initialize and search %load-path from ice-9 to C
7986 code, so we can use the load-path to find the ice-9 boot code;
7987 this makes it easier to run Guile without installing it. See
7988 corresponding changes in guile/Makefile.in.
7989 * feature.c: Move stuff concerned with the load path to load.c.
7990 (scm_compiled_library_path): Deleted.
7991 Don't #include libpath.h here.
7992 * feature.h: Don't mention scm_compiled_library_path.
7993 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
7994 <sys/stat.h>, and <unistd.h> (if present).
7995 (R_OK): #define if the system hasn't deigned to.
7996 (scm_loc_load_path): New variable.
7997 (scm_init_load_path, scm_sys_search_load_path,
7998 scm_sys_try_load_path): New functions.
7999 (scm_init_load): Initialize scm_loc_load_path to point to the
8000 value cell of the Scheme %load-path variable.
8001 * load.h: Add declarations for scm_sys_search_load_path,
8002 scm_sys_try_load_path.
8003 * init.c: Call scm_init_load_path.
8004 * Makefile.in (feature.o, load.o): Dependencies updated.
8006 * load.c, load.h: Rewrite using PROTO macro.
8008 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8010 * gc.c (scm_cellp): New function: C predicate to determine if an
8011 SCM value can be regarded as a pointer to a cell on the heap.
8013 * gc.h: Added declaration of scm_cellp.
8015 * gdb_interface.h: New file: The GDB interface header from the GDB
8018 * gdbint.c: New file: GDB interface.
8020 * gdbint.h: New file: GDB interface.
8022 * libguile.h: Added #include <libguile/gdbint.h>.
8024 * init.c (scm_boot_guile): Added scm_init_gdbint.
8026 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
8027 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
8028 found if object files and source are kept separate).
8030 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8032 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8034 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8036 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8037 TK_SRC_DIR; they're not relevant any more.
8039 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8040 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8042 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8044 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8045 search path, so we can find the <libguile/MUMBLE.h> headers.
8047 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8049 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8050 implicit in the .c.o rule.
8051 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8054 Put the library path in a header file, instead of passing it on
8055 the command line in every compilation.
8056 * Makefile.in (libpath.h): New target.
8057 (feature.o): Depend on libpath.h.
8058 (clean): Delete libpath.h.
8059 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8060 * feature.c: ... #include "libpath.h" here.
8061 * .cvsignore: Ignore libpath.h.
8063 Don't install the unwashed masses of Guile header files in the
8064 main #include path; put most of them in a subdirectory called
8065 'libguile'. This avoids naming conflicts between Guile header
8066 files and system header files (of which there were a few).
8067 * Makefile.in (pkgincludedir): Deleted.
8068 (innerincludedir): New variable; this and $(includedir) are enough.
8069 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8070 (installed_h_files): Divide this up. Now this variable lists
8071 those header files which should go into $(includedir) (i.e. appear
8072 directly in the #include path), and ...
8073 (inner_h_files): ... this new variable says which files appear in
8074 a subdirectory, and are referred to as <libguile/mumble.h>.
8075 (h_files): List them both.
8076 (install): Create innerincludedir, not pkgincludedir. Put
8077 the installed_h_files and inner_h_files in their proper places.
8078 (uninstall): Corresponding changes.
8079 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8080 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8081 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
8082 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
8083 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
8084 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8085 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8086 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8087 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8088 vports.h, weaks.h: Find __scm.h in its new location.
8089 * __scm.h: Find scmconfig.h and tags.h in their new locations
8090 (they're both "inner" files).
8092 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8094 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8096 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8098 * posix.c: Doc fixes.
8100 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8102 * socket.c: Don't include a prototype for inet_aton; just use a
8103 K&R style declaration, to avoid warnings but minimize the chance
8104 of conflicts with the system.
8106 On NextStep, <utime.h> doesn't define struct utime, unless we
8107 #define _POSIX_SOURCE before #including it.
8108 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8109 * acconfig.h: New comment text for above CPP symbol.
8110 * configure.in: Call it.
8111 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8113 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8115 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8116 testing for __EMX__.
8118 * posix.c: #include <libc.h>, if it exists.
8120 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8121 don't even know if the latter exists.
8123 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8124 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8125 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8127 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8129 (scm_init_posix): Use them when initializing the Scheme constants
8132 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8134 * Makefile.in (libdir, includedir, bindir): Use the
8135 autoconf-supplied values, instead of deriving them ourselves.
8136 (pkgincludedir, datadir, pkgdatadir): New variables.
8137 (install, uninstall): Put the header files in a special
8138 subdirectory, not in the main search path.
8140 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8141 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8143 * Makefile.in (IMPLPATH): Deleted; never used.
8145 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8146 on the Tcl/Tk source any more.
8147 (INCLUDE_CFLAGS): Remove references to the above.
8149 * Makefile.in (version.o): Corrected dependencies.
8151 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8153 * libguile.h: #include "version.h"
8155 * init.c (scm_boot_guile): Call scm_init_version.
8156 * gscm.c (gscm_run_scm): Call scm_init_version.
8158 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8159 GUILE_VERSION): AC_DEFINE these.
8160 (acconfig.h): #undef the above symbols.
8162 * Makefile.in (libobjs): Add version.o.

8166 (version.o): New rule.
8167 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8168 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

8177 weaks.o): Add version.h to dependency lists.
8178 (markers.o): Remove duplicate rule.
8180 * version.h: New file.
8182 * version.c: New file.
8184 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8186 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8187 array; use it appropriately. Since GCC is quite happy to
8188 subscript functions, it never warned us about this; we should use
8189 -Wpointer-arith in the future. I guess we never tested
8192 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8194 * socket.c: Doc and copyright fixes.
8196 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>

8200 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8202 * socket.c: Added declaration of inet_aton to avoid compiler
8203 warning. (Hope this solution is correct.)
8205 * stime.c: Added declaration of ftime. (This is missing in
8208 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
8210 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8212 * Makefile.in (c_files): add strerror.c.
8214 * strerror.c: new file from Emacs' sysdep.c.
8215 maybe configure should also check for sys_errlist.
8217 * configure.in (AC_REPLACE_FUNCS): add strerror.
8219 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8221 * debug.c (scm_init_debug): Added initialization for
8222 scm_evaluator_traps.
8224 * debug.h, debug.c: Various name changes.
8225 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
8226 "debug-options-interface". See commentary in options.c.
8228 * options.h, options.c: Options now have documentation strings.
8229 Also added a long explanatory commentary.
8231 * eval.c, print.h, print.c, read.h, read.c: Modifications to
8234 * gscm.c, init.c, root.c, throw.c: Bug fixes:
8235 last_debug_info_frame is now updated in all cases.
8237 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
8240 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8242 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
8243 Added option STACK_CHECKING.
8245 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8247 * Makefile.in: Added {debug,options,srcprop}.{h,c}
8249 * __scm.h: Removed symbols for debugging support.
8251 * acconfig.h: Added symbols for debugging support.
8253 * configure.in: Added user option for debugging support.
8254 --enable-debug will include the debugging code into libguile.a.
8256 * continuations.c (scm_make_cont): Enlarged the #if 0 around
8257 scm_relocate_chunk_to_heap.
8259 * debug.c: New file: low-level debugging support. It also
8260 includes support for debugging with gdb. (The extensions to gdb
8261 are written by Per Bothner at Cygnus.)
8263 * debug.h: New file: low-level debugging support.
8265 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
8266 argument pairs. Extensive modifications to the debugging
8267 evaluator. Added "SECTION:" commentaries to clarify what happens
8268 when, during double compilation. Renamed EVALIMP --> EVALIM.
8269 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
8270 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
8271 the beginning of the file. New procedure: scm_unmemocopy.
8272 Added some global state variables needed by the debugging
8273 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
8274 check_entry, check_apply, check_exit, debug_options and
8275 evaluator_traps. New acro: undefine.
8277 * eval.h: Renamed EVAL --> XEVAL.
8279 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
8280 --> scm_make_weak_key_hash_table.
8282 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
8283 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
8285 * libguile.h: Conditionally include debug.h
8287 * objprop.c (scm_object_properties, scm_set_object_properties_x):
8288 scm_object_properties shouldn't return handle. `handle' now gets
8289 initialized in scm_set_object_properties_x. scm_object_properties
8290 doesn't any longer create an entry in scm_object_whash.
8292 * options.c: New file: handling of run time options.
8294 * options.h: New file: handling of run time options.
8296 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
8298 * print.c: New procedure: scm_print_options
8300 * print.h: Defines for print options.
8302 * read.c: New procedure: scm_read_options
8304 * read.h: Defines for reader options.
8306 * root.h: Added scm_source_whash among scm_sys_protects.
8308 * srcprop.c: New file: source properties.
8310 * srcprop.h: New file: source properties.
8312 * throw.c (jbsmob): Jump buffers are now correctly allocated.
8313 (Bug found by A. Green.)
8315 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8317 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8319 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
8321 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8323 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8324 and should be called by the final client.
8326 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8328 * gc.h: Use the PROTO macro when declaring functions.
8329 * gc.c: Use the PROTO macro when declaring static functions.
8330 Remove the CPP hair around function definitions.
8332 * gc.c (scm_init_storage): Initialize scm_asyncs.
8334 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8335 preprocessor symbol; "__scm.h" is where it might get #defined.
8336 * __scm.h: Similar: #include <scmconfig.h> before testing
8339 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8341 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8343 * init.c (scm_boot_guile): Add init_func argument; call
8344 (*init_func) instead of calling scm_appinit; it's ucky to
8345 hard-code names for the user's procedures.
8346 * init.h (scm_boot_guile): Adjust declaration.
8348 * __scm.h (PROTO): New macro, for declaring functions with
8351 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8352 eliminate all the __STDC__ conditionals.
8353 (scm_boot_guile): Add declaration.
8354 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8355 Remove __STDC__ conditionals around function definitions; the
8356 declarations in init.h will provide the same information, more
8359 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8360 complain about it in the error message; the error message is
8361 adequate without that note, and there's nothing the user can do
8364 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8366 * Makefile.in (ancillary): Drop def.sed.
8368 * posix.c (scm_init_posix): Use numeric values, rather than
8369 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8370 F_OK. The symbols aren't available on some systems, and I'm
8371 pretty sure their values are fixed by common widespread practice.
8372 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8374 More functions unavailable on some systems.
8375 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8376 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8378 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8379 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8380 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8381 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8382 stub that signals an error as the #else.
8384 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8386 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8388 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8390 * unif.c: include ramap.h.
8392 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8394 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8396 * ports.c: include sys/ioctl.h.
8398 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8400 * configure.in: check for sys/ioctl.h.
8402 * ports.c: include <malloc.h> not "malloc.h".
8404 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8406 * fports.c: remove ttyname and tmpnam declarations.
8408 * posix.c: fewer ttyname declarations.
8410 * fports.c: include <string.h> not "string.h".
8412 * init.c, ioext.c: include string.h and unistd.h.
8414 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8416 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8417 genio.c, simpos.c, vports.c: include string.h.
8419 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8421 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8423 (scm_addr_buffer_size): change type from scm_sizet to int.
8424 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8425 from scm_sizet to int.
8427 * error.c: include unistd.h.
8429 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8432 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8434 * __scm.hd, def.sed: deleted.
8436 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8438 Changes for NeXT, suggested by Robert Brown.
8439 * configure.in: Call AC_TYPE_MODE_T.
8440 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8441 NeXT. Put header file list in alphabetical order.
8442 * configure, scmconfig.h.in: Regenerated.
8443 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8445 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8448 * acconfig.h: New file, providing documentation for the CPP
8449 symbols defined in configure.in
8450 * acconfig-1.5.h: Removed; superceded by the above.
8452 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8454 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8456 * fports.c (scm_open_file): don't return #f, throw error.
8458 * ioext.c (fileno): renamed from %fileno.
8459 (soft-fileno): deleted.
8461 * ports.c (scm_port_revealed): don't need to check for -1 from
8463 (scm_set_port_revealed_x): return unspecified, not #f.
8465 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8467 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8469 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8471 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8473 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8475 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8476 This is necessary on Ultrix, and doesn't hurt portability.
8478 * Makefile.in (dist-dir): New target, implementing a new dist system.
8479 (installed_h_files): Put in alphabetical order.
8480 Remove duplicate entries for markers.h and unif.h.
8481 (c_files): Remove duplicate entries for markers.c.
8482 (ancillary): Renamed from anillery; all uses changed. Remove
8483 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8484 Remove all the ../doc/* files; doc/Makefile.in handles that.
8486 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8488 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8489 every if must have an else, or else the whole command has a
8490 non-zero exit code whenever the if's condition is false.
8492 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8494 * posix.c: include string.h.
8496 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8498 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8501 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8502 Remove leading % from scheme names.
8503 Do not return error values, call SCM_SYSERROR or similar.
8505 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8507 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8509 * struct.c (scm_init_struct): new file.
8511 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8513 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8514 (scm_list_head): added list-head for rapidly chopping argument
8515 lists off of longer lists (and similar).
8517 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
8519 * objprop.c (scm_object_property): assq the cdr of the whash
8520 handle for obj, not the handle itself.
8522 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8524 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8525 weak hash tables last of all marking to avoid an obscure gc bug.
8526 WARNING: circular lists stored in a weak hash table will hose us.
8528 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8530 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8531 new functions similar to scm_substring_move_left_x and
8532 scm_substring_move_right_x.
8534 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8536 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
8539 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
8541 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8543 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8545 * strports.c (scm_strprint_obj): convenience function. C for
8546 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8548 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8549 removed to a separate library
8551 * init.c (scm_boot_guile): copied from guile-tcl.c.
8552 Initialization specific to tcl interpreters removed.
8554 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8556 * ports.c (scm_ports_prehistory): size malloced here doesn't
8557 matter so long as it is non-0 (got rid of "* 4").
8559 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8561 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8562 since its definition was bogus).
8564 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8566 * mallocs.[ch]: back again (for rx at least).
8568 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8570 * ports.c: removed functions relating to the mapping between ports
8571 and descriptors. (That stuff is unix-specific and should be collected
8572 in a separate library).
8574 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
8575 (Tom Mckay@avanticorp.com)
8577 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
8579 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8580 handled correctly (SCM_FREEP was applied to them) -- test for
8581 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
8582 being overwritten with #f. (brown@grettir.bibliotech.com)
8584 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
8586 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
8587 for a specific symbol or for all symbols.
8589 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
8591 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
8592 keys and weak values confused).
8594 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
8596 * list.c (scm_last_pair): map '()=>'()
8598 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
8600 * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
8601 Generalized assoc and hash-table functions.
8602 Factored pairs.c into multiple files.
8604 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
8606 * gscm.c (gscm_run_scm): got rid of objprop.
8608 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
8610 * genio.c (scm_getc):
8611 NOTE: fgetc may not be interruptable.
8613 * procprop.c (scm_stand_in_scm_proc):
8614 NOTE: don't use a alist here.
8615 (scm_set_procedure_properties_x): fix type checking throughout this file.
8617 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
8619 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
8620 after freeing part of the port table.
8622 Thu Feb 29 16:21:17 1996 Tom Lord <lord@beehive>
8624 * strports.c (scm_mkstrport):
8625 * vports.c (scm_make_soft_port): allocate a port table entry
8626 (possibly triggering gc) before setting the tag of the corresponding
8629 * pairs.c (scm_delq_x): never throw an error.
8631 * vectors.c (scm_make_vector): made the default vector fill argument
8632 into '() (much more useful than the previous value, "#unspecified")
8634 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
8636 * ports.c (scm_add_to_port_table): Added fields
8637 to port table entries: file_name, line_num, col.
8638 Update these in open_file, gen_getc and gen_ungetc.
8639 Added procedures to access those fields.
8641 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
8643 * procs.c (scm_make_subr_opt): new entry point for making
8646 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
8648 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
8650 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
8652 * numbers.c (scm_exact_p): This function no longer
8653 implements "integer?".
8655 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
8657 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
8658 (scm_gc_stats): return an assoc of useful data. Replaces "room"
8659 and the stats reporting formerlly built into repl.
8661 * repl.[ch]: removed.
8662 GC statistics keeping moved to gc.c.
8663 Other statistics keeping can be done from Scheme.
8664 REPLS are now written in Scheme.
8666 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
8668 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky
8669 conservatively marked objects).
8671 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
8673 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
8675 * feature.c (scm_compiled_library_path): moved here from repl.c.
8676 This file is for stuff relating specifically to Scheme libraries
8679 * eval.c (scm_m_define): don't give warning about redefinition, don't
8682 NOTE: this should throw a resumable exception with parameters --
8683 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
8685 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
8687 * error.c: scm_warn eliminated.
8689 * read.c (scm_lreadr): extra right paren gets an error, not a warning.

8692 lose exit_report, growth_mon.
8694 * gscm.c: got rid of verbosity functions.
8696 Tue Feb 20 00:19:10 1996 Tom Lord <lord@beehive>
8698 * throw.c (scm_ithrow): guard against the bad-throw hook changing
8699 between the call to procedurep and use.
8701 * error.c (scm_everr):
8703 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
8706 * strports.c: don't reveal the port's string to the caller
8707 because it changes size.
8709 (stputc stwrite): check/change the strings length with interrupts
8712 * objprop.c (scm_set_object_property_x &c): use the generic
8713 hashing functions and be threadsafe.
8715 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
8716 (per suggestion jaffer@gnu.ai.mit.edu).
8718 * mbstrings.c (scm_multi_byte_string): guard against argument list
8721 * strings.c (scm_make_string): loop cleanup
8723 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer
8726 * weaks.c (scm_weak_vector): guard against argument list
8729 * variable.c (scm_builtin_variable): check for/make a built-in
8732 * vectors.c (scm_vector): while filling the new array,
8733 guard against a list of fill elements that grows after
8734 the vector is allocated.
8736 * hashtab.c -- new file: general hash table
8737 functions. hash, hashq, hashv, hashx.
8739 * tags.h: made wvect an option bit of vector.
8741 Mon Feb 19 09:38:05 1996 Tom Lord <lord@beehive>
8743 * symbols.c: made the basic symbol table operations atomic.
8745 * root.c &c.: collected stack-specific global state.
8746 linum/colnum etc *should* be port-specific state.
8748 * struct.c (scm_init_struct): init the first struct type during
8749 initialization to fix a race condition.
8751 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
8752 object, not in a global.
8753 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
8755 * throw.c (_scm_throw): Pass throwval on the stack, not in a global
8756 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
8758 * *.[ch]: namespace cleanup. Changed all (nearly) exported CPP
8759 and C symbols to begin with SCM_ or scm_.
8761 Sun Feb 18 15:55:38 1996 Tom Lord <lord@beehive>
8763 * gsubr.c (scm_gsubr_apply): statically allocate the
8764 array of arguments (bothner@cygnus.com).
8766 Sat Feb 17 20:20:40 1996 Tom Lord <lord@beehive>
8768 * scmsigs.c: Simplified to use async rountines.
8770 * async.c: New support for interrupt handlers.
8772 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
8774 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
8775 set the multi_byte flag correctly in symbols. This is wrong.
8776 intern_obbary_soft and msymbolize should take an extra parameter.
8777 Also, weird multibyte symbols don't print correctly.
8778 The weird symbol syntax is also a bit bogus (emacs doesn't quite
8781 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
8783 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
8784 use the system symhash. == #t means create an uninterned symbol.
8786 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
8788 * strings.c (scm_make_shared_substring): build'em.
8789 It might better to keep a table of these and use one
8790 less cons-pair per shared-substring.
8792 Tue Feb 6 17:45:21 1996 Tom Lord <lord@beehive>
8794 * strings.c (scm_string_shared_substring): create shared
8795 substrings. (Doesn't handle mb strings yet).
8797 * mbstrings.c (scm_print_mb_string): handle RO strings.
