1 1999-09-03 James Blandy <jimb@mule.m17n.org>
3 * load.c (scm_search_path): If the filename has any extension at
4 all, ignore the entire list of extensions. Also, don't check whether
5 the file is accessible. If the file exists, accessible or not, we
6 should return it. Inaccessible files should cause an error later.
7 (Thanks to Keisuke Nishida for the suggestions.)
9 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
11 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
12 atexit not available. (sunos4.1.4 needs it.)
14 1999-09-01 James Blandy <jimb@mule.m17n.org>
16 I take it all back --- bcopy does handle overlapping source and
17 destination areas correctly. At least on every system I could
18 find. But it is better to use AC_REPLACE_FUNCS than to introduce
20 * memmove.c: New file, implementing memmove in terms of bcopy.
21 * scmconfig.h.in: Regenerated.
23 Allocators should use the `void *' type for generic pointers.
24 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
25 argument and return types.
26 * gc.h: Corresponding changes to prototypes.
29 1999-08-31 James Blandy <jimb@mule.m17n.org>
31 * numbers.c (scm_init_numbers): Claim to support the `complex'
32 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
34 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
35 find (ice-9 boot-9) when Guile was compiled in a separate
36 directory from the source. (Thanks to Rodney Brown.)
37 * Makefile.in: Regenerated.
39 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
40 table lengths by the size of a single element when growing the
41 table. (Thanks to Bill Schottstaedt.)
43 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
45 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
46 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
47 since that cuts down the time for type dispatch by 50%.
49 1999-08-30 James Blandy <jimb@mule.m17n.org>
51 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
52 not a correct substitute for memmove, because it doesn't handle
53 overlapping source and destination areas on many platforms.
54 Overlaps are the primary reason to use memmove in the first place.
55 * ports.c (scm_ungetc): Same.
56 * strop.c (scm_substring_move_x): Same.
58 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
60 * gc.c (scm_init_storage): Skip registration of cleanup on systems
61 which lack atexit. (Is it important that cleanup is made
62 properly? Maybe we should replace all `exit' with `scm_exit' and
65 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
66 scm_struct_free_standard, scm_struct_free_entity): Declared to
67 return scm_sizet instead of size_t.
69 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
72 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
74 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
75 Account for the case when second argument is unbound.
77 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
78 (Thanks to Karoly Lorentey.)
80 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
81 isn't present. (Thanks to Suzuki Toshiya.)
83 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
86 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
89 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
90 Bernard Urban and Ian Grant.)
92 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
93 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
94 change in the representation of entities and operators.)
96 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
98 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
99 don't allocate zero bytes (thanks to Bill Schottstaedt).
101 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
103 * procs.c (scm_setter): Converted to use generic dispatch.
105 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
108 * load.c (scm_search_path): Don't try extensions which already are
109 present at the end of the filename.
110 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
112 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
114 Cleanup and simplification of generic method dispatch.
115 Also, the quadruple representation of entity and operator
116 procedures has been replaced with single.
118 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
120 * print.c (scm_isymnames): Removed #@hash-dispatch.
122 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
123 from eval.c; Support 0 arity methods.
124 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
125 (scm_apply_generic_env): Removed.
126 Replaced slots proc0-3 with procedure.
128 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
129 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
130 SCM_OPERATOR_PROCEDURE.
131 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
132 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
134 * struct.c, struct.h: Replace 4 procedure slots with one.
135 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
137 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
140 * eval.c (scm_sym_args): Removed.
141 (SCM_CEVAL): Simplified entity application.
142 Moved dispatch code to objects.c.
144 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
146 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
148 * sort.c (closureless): Use scm_eval_body.
150 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
151 with a symbol as last form was first called normally and then via
152 `map' or some other mechanism using primitive apply, an ILOC was
155 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
157 This change extends the representation of primitive procedures
158 with more data fields, e.g. a place for documentation and true
159 procedure properties.
161 * procs.c, procs.h (scm_subr_entry): New type: Stores data
162 associated with subrs.
163 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
164 SCM_SUBR_DOC): New macros.
165 (scm_subr_table): New variable.
166 (scm_mark_subr_table): New function.
168 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
170 * gc.c (scm_gc_mark): Don't mark subr names here.
171 (scm_igc): Call scm_mark_subr_table.
174 This change implements a scheme for letting a generic work as a
175 shadow for a primitive procedure. If the primitive procedure
176 can't dispatch on its arguments, control is left over to the
177 generic. Normal wrong type arg errors will be generated until the
178 user has hung the first method on the primitive.
180 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
182 * procs.c, procs.h (scm_subr_p): New function (used internally).
184 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
186 * objects.c, objects.h (scm_primitive_generic): New class.
188 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
190 * print.c (scm_iprin1): Print primitive-generics.
192 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
193 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
195 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
196 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
197 primitives). NOTE: This means that it is now *required* to use
198 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
199 obscured representation that will be removed in the future anyway,
200 so backward compatibility is no problem here).
202 * numbers.c: Converted most numeric primitives (all but bit
203 comparison operations and bit operations) to dispatch on generic
207 Better support for applying generic functions.
209 * eval.c, eval.h (scm_eval_body): New function.
211 * objects.c (scm_call_generic_0, scm_call_generic_1,
212 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
216 Optimization of the generic function dispatch mechanism.
218 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
219 called scm_memoize_method instead of doing a second lookup.
221 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
226 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
227 scm_sysintern so that the binding connected with the subr name
228 isn't cleared when we give set = 0.
231 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
233 More transparent handling of ports with print states.
235 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
236 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
237 instead of a pair of a port and a print state. We'll need to cons
238 once extra in scm_printer_apply but the type system will be
239 cleaner, it will mix better with GOOPS, and, it will be even more
240 transparent to the user.
242 * print.c (scm_get_print_state): New procedure: Given an output
243 port, return the print state associated to it in the current print
244 chain, if one exists;
245 (scm_port_with_print_state): New procedure: Associate a
246 print-state with a port.
247 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
248 (scm_printer_apply): Wrap port and pstate as a smob;
249 (print_state_printer): Removed.
251 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
253 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
256 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
257 testing (otherwise the port-print-state trick won't be transparent
258 to the user; one example where this caused problems was in the
259 (ice-9 format) module).
261 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
263 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
264 SCM_UNSPECIFIED instead of the set value.
266 1999-08-20 James Blandy <jimb@mule.m17n.org>
268 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
270 * ports.h (enum scm_port_rw_active): New enum, containing
271 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
272 zero). The debugger knows about enums, but doesn't know about
274 (typedef scm_port): Declare rw_active member to be an enum
276 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
278 * ports.c (scm_add_to_port_table): Same.
279 * strports.c (st_flush, st_end_input): Same.
281 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
282 scm_must_realloc, and scm_done_malloc as appropriate.
284 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
286 * sort.c (quicksort): Added condition to protect the algorithm
287 from crashing the interpreter if the less predicate is buggy.
289 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
291 * fports.c (fport_write): fix line-buffering mode again.
292 (scm_open_file): recognise 'l' for line-buffering.
293 (scm_setvbuf): recognise _IOLBF for line-buffering.
295 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
297 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
300 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
303 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
305 * fports.c (fport_write): use memcpy instead of strncpy, in case
306 the data contains NUL.
308 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
310 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
312 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
313 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
314 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
315 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
316 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
317 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
318 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
319 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
320 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
321 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
322 scm_sym_ as prefix for symbols.
324 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
326 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
327 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
328 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
329 scm_sym_atcall_cc): Made global.
331 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
333 * eval.c (scm_sym_args): Made global.
335 * objects.c (scm_set_object_procedure_x): Disallow setting of
336 procedures for pure generic functions.
338 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
340 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
341 Scheme name from lseek to seek, but lseek was added recently so
342 it shouldn't be a big problem.
343 * ports.c, gdbint.c, ioext.c: changed callers.
345 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
347 * fports.c (fport_input_waiting): if select is used, return 1
348 instead of whatever FD_ISSET expands to. maybe it will be useful
349 to interpret the value from the input_waiting ptob procedure as a
350 lower bound on the number of bytes available.
352 * Mikael asked for a few names to be changed...
354 * ports.c (scm_make_port_type): take the write procedure as the
355 second argument instead of the flush procedure.
356 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
357 fflush -> flush, read_flush -> end_input, fclose -> close,
358 fill_buffer -> fill_input, ftruncate -> truncate,
359 input_waiting_p -> input_waiting.
361 * ports.c (end_input_void_port): was read_flush_void_port.
362 (scm_set_port_end_input): was scm_set_port_flush_input.
363 (scm_set_port_flush): was scm_set_port_write.
364 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
365 (scm_end_input): was scm_read_flush.
366 (scm_fill_input): was scm_fill_buffer.
367 (scm_flush): was scm_fflush.
368 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
369 (fport_end_input): was local_read_flush.
370 (fport_flush): was local_fflush.
371 (fport_close): was local_fclose.
372 (fport_truncate): was local_ftruncate.
373 (fport_seek): was local_seek.
374 (fport_free): was local_free.
375 (fport_fill_input): was fport_fill_buffer.
376 * strports.c (st_end_input): was st_read_flush.
377 (st_truncate): was st_ftruncate.
378 * vports.c: (sf_flush): was sfflush.
379 (sf_close): was sfclose.
380 (sf_fill_input): was sf_fill_buffer.
382 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
385 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
387 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
388 forms now contain the expressions to be dispatched upon instead of
389 depending on a surrounding lambda or let; Generic function
390 dispatch has been optimized; `apply' on a generic function now
391 works a little bit strangely. It uses a trick so that the type
392 dispatch code in SCM_CEVAL can be reused.
394 * objects.h, objects.c (scm_apply_generic_env): Added (used by
396 (scm_operator_p): Added.
397 (scm_sym_atdispatch): Added.
398 (scm_set_object_procedure_x): Modified to handle the new style
400 (scm_object_procedures): New debugging procedure.
402 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
404 * eval.c, eval.h (scm_sym_args): Added.
406 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
408 * feature.c, feature.h (scm_c_run_hook): Added.
410 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
411 cdrxnoap and loopnoap instead of begin and loop.
413 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
415 * ports.c (scm_putc, scm_puts),
416 * unif.c (scm_uniform_array_write): use scm_lfwrite.
417 * ports.c (scm_putc): change type of first argument from int to char.
419 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
421 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
422 SCM_IM_HASH_DISPATCH.
424 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
425 (scm_si_redfined, scm_si_hashsets): Moved.
427 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
428 flag which combines type and status info so that the class
429 redefinition protocol has zero cost during normal execution.
431 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
433 * ports.h (scm_ptob_descriptor): include a write procedure again.
434 it's more efficient for unbuffered fports (e.g., sockets.)
436 * ports.c (scm_puts): use ptob->write.
437 * vports.c (scm_make_sfptob): set write proc in ptob.
438 * strports.c (scm_make_stptob): set write proc in ptob.
439 * ports.c (write_void_port): new procedure.
440 * vports.c (sf_write): new procedure.
441 * ports.c (scm_lfwrite): use ptob->write.
442 * strports.c (st_write): new procedure.
443 * fports.c (fport_write): new procedure.
444 (scm_make_fptob): set write in ptob to fport_write.
445 * ports.h: prototype for scm_set_port_write.
446 * ports.c (scm_make_port_type): initialise ptob write procedure.
447 (scm_set_port_write): new proc.
449 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
451 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
452 until we've verified that it is actually a port. (Thanks to
455 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
457 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
458 code, particularly an unnecessary test (len != size, where len ==
459 size). (Was this leftovers from debugging code, or have I missed
462 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
463 size. (Thanks to James Dean Palmer.)
465 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
466 (Thanks to Lorentey Karoly.)
468 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
470 * eval.c (scm_m_expand_body): Use scm_cons_source.
472 * struct.c (scm_print_struct): Use vtable name.
474 * print.c (scm_init_print): Set name of print state type.
476 * stacks.c (scm_init_stacks): Set name of stack type.
478 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
480 * eval.c (SCM_CEVAL): Removed old implementation of internal
483 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
485 * debug.c, debug.h (scm_reverse_lookup): Added.
486 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
487 internal procedure definitions; Don't use scm_i_inner_name.
489 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
492 * eval.h: Added prototypes for multi language support functions.
494 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
495 improper lists in the low-level representation, since that will
496 cause a begin to be prepended at macro expansion.
498 * eval.c (scm_cons_source): Version of cons which copies source
499 properties from an existing cell.
500 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
502 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
503 procedure source before calling scm_unmemocopy instead of faking
506 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
508 Ported `internal defines' fix from SCM. Original ChangeLog entry:
510 1998-07-09 Radey Shouman <radey@colorage.com>
512 * eval.c (ceval_1): Modifications to allow rewriting of interal
513 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
514 body of which it is the CAR is macro expanded by m_expand_body,
515 which rewrites internal DEFINE.
517 (m_expand_body): Added.
519 (m_macroexp1): Added argument to control error checking:
520 m_expand_body may speculatively expand forms in the wrong
521 environments. Made argument number checks conditional on
524 (m_body): Added, error checks bodies and inserts the ISYM tokens.
526 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
529 (m_cond): (m_case): (m_quote): Modified to avoid destructively
530 changing their argument forms. Since m_expand_body
531 speculatively macro expands forms the process must be
534 (m_ident_eqp): Fixed to use proper environment.
536 (renamed_ident): Added DEFER_INTS_EGC.
538 Added prototypes for static functions.
544 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
545 is false, do not produce an error for unbound variables, return a
546 pointer to cell_undef instead.
548 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
552 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
553 destructively changing their argument forms. Since m_expand_body
554 speculatively macro expands forms the process must be reversible.
556 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
557 SCM_IM_LET introduced by named lets.
559 (scm_m_letstar): Use scm_m_body instead of bodycheck.
561 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
562 scm_letrec. scm_letrec1 does not check for a null binding and
563 takes an additional argument to specify the ISYM of the body. Use
564 scm_m_body instead of bodycheck.
566 (scm_m_let): Use scm_m_body instead of bodycheck.
568 (scm_m_expand_body, scm_macroexp): New.
570 (unmemocopy): Account for ISYMs introduced by scm_m_body.
572 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
573 check=1. Throw error for internal defined that have not been
574 rewritten by scm_m_expand_body.
576 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
577 Removed prototype for SCM_APPLY.
579 * tags.h: Added extern declaration of scm_isymnames.
581 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>

585 * lang.c: New file: Beginning of multi-language support.
587 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
589 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
590 (scm_dynamic_wind): Added argument checking for the after guard so
591 that we don't add garbage on the dynwind chain.
592 (scm_swap_bindings): Added.
594 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
595 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
596 (scm_isymnames): New isyms for multi-language support.
598 * eval.c (scm_nil, scm_t): New symbols.
599 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special

616 scm_set_ptob_XXX --> scm_set_port_XXX.
618 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
620 * ports.c, ports.h (scm_make_port_type): New interface for
621 creation of port types (replaces scm_newptob). Just as for the
622 smobs, we need to separate the internal representation of smob
623 types from the interface, so that we easily can add new fields and
624 rearrange things without caring about backward compatibility.
625 This change was forced by the need in GOOPS to create classes
626 representing port types.
627 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
628 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,

637 (void_port_ptob, print_void_port, close_void_port, noop0):
638 Removed. Removed #include "genio.h" Added #include "objects.h",
641 * fports.c (prinfport): Moved code from ports.c.
643 (scm_fptob): Removed. Instead use new interface.

650 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
651 (scm_make_sfport): Added.

674 * filesys.c (scm_truncate_file): removed.
676 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
678 * readline.c, readline.h: Removed.
680 * objects.c, objects.h (scm_port_class): Added.

686 * Makefile.am: Removed genio.c, genio.x.
690 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
692 * init.c: Make sure that scm_post_boot_init_modules is called only
693 once. (Important when using a dumped image.; Thanks to Bernard
696 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
698 * guardians.c (scm_guardian_zombify): Separate scanning for
699 zombies from marking the pairs of the free list.
701 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
702 use the macros. (Thanks to Michael Livshin.)
704 * eval.c (scm_m_lambda): Let bodycheck check the body of the
705 lambda. Let your sins be purified by the blood of the lambda.
706 (Thanks to Eric Hanchrow.)
708 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
709 (Thanks to Valdis Kletnieks.)

713 * filesys.c: #include <io.h>, if we have it.
714 * scmconfig.h.in: Regenerated.
716 * stime.c (ftime): Delete declaration for this function --- let
717 the system supply it.
719 Cleanups from John Bley.
721 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
723 * gsubr.c: Don't include "gsubr.h" twice.
725 Cleanups for compilation on Irix 6, from David Kaelbling.
727 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
728 regex_t pointer. This is what the callers have, mostly.
729 (scm_regexp_exec): Don't forget to pass the `rx' argument to
730 scm_regexp_error_msg.
732 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
733 int. That way, if we get a warning on this line, it's more likely
734 that we're really missing bits we care about.
736 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
739 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
740 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
741 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
742 cast at all is more appropriate in every case. At the moment, we
743 assume everywhere that SCM is an integral type anyway.
745 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
747 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
748 read_pos after scm_fill_buffer.
750 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
753 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
754 fports.c (fport_fill_buffer): implement the interface change.
756 * ports.c (scm_fill_buffer): interface change: no longer increments
757 read_pos past the character that's returned. it seems clearer to
758 leave it to the caller to decide what to do (thanks Jim).
760 * vports.c (sf_fill_buffer): put the read char into the buffer
761 as well as returning it.
763 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure

783 to be maintained for output ports too (it holds the written
784 part of the string, while write_buf may have unwritten buffer
786 (st_truncate): rewritten.
787 (top of file): added a few notes.
789 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
791 Patch from Greg Badros:
792 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
793 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
794 (function pointer) argument to scm_make_gsubr and scm_make_subr
795 calls. This avoids warnings in C++ programs using guile-snarf.
797 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
799 * strports.c (st_grow_port): set pt->read_pos. set
800 pt->read_buf_size one less than pt->write_buf_size if there's

803 (st_resize_port): renamed from st_grow_port.
804 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.

923 * struct.c, struct.h:
925 In order to support different kinds of deallocation, a destructor
926 slot has been added to struct vtables. This allows for structs
927 containing pointers to other memory blocks.
929 (scm_struct_i_free): New hidden struct slot. Holds destructor for
930 instances to this vtable.
931 (scm_struct_free_0): New destructor: Doesn't deallocate data.

1050 vectors without allocating new storage during GC, using
1051 scm_weak_vectors as the head of the chain.
1052 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1053 instead of stepping through an array.
1054 (scm_gc_sweep): Update offset used to find start of weak vector to

1066 * fports.c (local_seek): Signal an error if the seek fails.
1067 * ports.c (scm_lseek): Don't check return value of port's seek

1079 actually correspond to the changes described below. I got the
1080 ChangeLog entries and the patch from two different places...
1082 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1084 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1085 it shows up as terrible performance, as we GC constantly.
1087 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
1088 newline. A bit faster, and definitely hairier.
1089 (scm_read_line): Count newlines here instead.
1091 * strings.c (scm_take_str): New function.
1092 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
1093 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use
1094 scm_take_str, to avoid copying the string.
1096 Add some simple-minded support for line buffered ports.
1097 * ports.h (SCM_BUFLINE): New flag for ports.
1098 * init.c (scm_init_standard_ports): Request line-buffering on
1099 the standard output port.
1100 * ports.c (scm_mode_bits): Recognize 'l' as a request for line
1102 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1103 and there's a newline to be written, flush the port.
1105 Gary Houston's open-buffer port patches:
1107 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1109 * ports.c: (scm_lseek): clear buffers even if just reading current
1112 * fports.c (local_fclose): call local_fflush unconditionally.
1113 (various): don't use the scm_must... memory procs.
1115 1999-04-25 Gary Houston <ghouston@easynet.co.uk>
1117 * ports.h (scm_port): make read_pos a pointer to const.
1118 strports.c: take care of rw_active and rw_randow.
1119 fports.c: scm_fport_drain_input: removed. do it all in ports.c.
1120 strports.c (scm_mkstrport): check that pos is reasonable.
1121 ioext.c (scm_ftell, scm_fseek): use lseek.
1122 (SCM_CLEAR_BUFFERS): macro deleted.
1123 ioext.c (redirect_port: use ptob fflush, read_flush.
1124 ports.h (scm_ptobfuns): add ftruncate.
1125 ports.c (scm_newptob): set ftruncate.
1127 ports.c (scm_ftruncate): new procedure.
1128 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.
1129 strports.c (st_seek, st_grow_port): new procs.
1130 fports.h (scm_port): change size types from int to off_t.
1131 ports.c (scm_init_ports): initialise the seek symbols here
1132 instead of in ioext.c.
1133 strports.c (scm_call_with_output_string): start with an empty
1134 string, so seek and ftruncate can be used.
1136 gdbint.c: adjust string port usage.
1138 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1140 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
1141 equivalent to fflush for the read buffer.
1142 * ports.c (scm_newptob): set read_flush.
1143 ports.c (void_port_ptob): set read_flush.
1144 fports.c (local_read_flush): new proc. add to ptob.
1145 strport.c (st_read_flush): likewise.
1146 vport.c (sf_read_flush): likewise.
1147 fports.h (struct scm_fport): remove random member. there's nothing
1148 left but fdes. leaving it as a struct to allow for future changes.
1149 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1150 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1151 ptob proc if the read buffer is filled.
1153 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1155 * ports.h (scm_port): add a rw_random member and replace
1156 reading and writing members with rw_active member.
1157 SCM_PORT_READ/SCM_PORT_WRITE: new values.
1159 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
1161 * ports.h (struct scm_port_table): add writing and reading members
1162 to replace write_needs_seek: it isn't good enough for non-fports.
1163 ports.c, ioext.c, fports.c: corresponding changes.
1164 (struct scm_port_table): give it a typedef and rename to scm_port.
1165 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
1166 corresponding changes.
1168 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
1170 * ports.c (scm_newptob): bugfix: set seek member.
1171 * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
1172 and generalised to all port types.
1174 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
1176 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
1177 signals (it was only being done for handlers installed from Scheme).
1178 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
1179 waiting for input caused an EINTR error from read.
1181 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
1183 * ports.h (struct scm_port_table): make all the char members
1184 unsigned, so they convert to int without becoming negative if large.
1186 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
1188 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
1189 with threads enabled. rename this procedure to
1190 fport_wait_for_input and take a port instead of a fdes.
1191 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
1193 * readline.c (scm_readline): Applied a patch from Greg Harvey to
1194 get readline support working again: use fdopen to get FILE objects.
1196 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
1198 * gc.c (scm_init_storage): install an atexit proc to flush the
1200 (cleanup): the new proc. it sets a global variable which can be
1201 checked by the ptob flush procs to avoid trying to throw
1202 exceptions during exit. not very pleasant but it seems more reliable.
1203 * fports.c (local_fflush): check terminating variable and if set
1204 don't throw exception.
1205 * CHECKME: that the atexit proc is installed if unexec used.
1207 * throw.c (scm_handle_by_message): don't flush all ports here.
1208 it still causes bus errors.
1210 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
1211 and move to ioext.c.
1213 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
1215 * ports.c (scm_char_ready_p): check the port buffer and call the
1216 ptob entry if needed.
1218 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
1219 ptob initialisers. use it in char-ready
1221 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
1223 * vports.c (sfflush): modified to write a char (since softports
1224 currently use shortbuf.)
1226 * fports.c (scm_standard_stream_to_port): moved to init.c and
1229 * init.c (scm_init_standard_ports): make stdout and stderr
1230 unbuffered if connected to a terminal. with stdio they
1231 were line-buffered by default.
1233 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
1236 * ports.h (scm_ptobfuns): change fflush return to void.
1237 change flush proc definitions.
1239 * strports.c (scm_call_with_output_string): get size from
1240 buffer instead of port stream.
1241 (st_flush): new proc.
1243 * ports.h (struct scm_port_table): added write_end member,
1244 as an optimisation. set it where write_buf_size is set.
1246 * ports.h (struct scm_port_table): change stream from void *
1247 back to SCM. SCM presumably must be large enough to hold a
1248 pointer (and probably vice versa but who knows.)
1249 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
1251 (scm_puts): rewritten
1252 * fports.c (local_ffwrite, local_fputs): removed.
1253 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)
1254 * vports.c (sfputc, sfputs, sfwrite) likewise.

1262 * ports.c (scm_add_to_port_table): initialise write_needs_seek.
1264 * ports.h (scm_ptobfuns): add seek function pointer.
1265 * fports.c: set it to local_seek, new procedure.
1268 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
1269 use ptob for seek. take ptob instead of fport arg.
1271 * ports.h (struct scm_port_table): new member write_needs_seek,
1272 replaces reading member in fport struct.
1274 * vports.c (sfgetc): store the getted char into the buffer.
1275 rename to sf_fill_buffer and install it for fill-buffer in ptob.
1276 the Scheme interface is still a procedure that gets a char.
1277 (scm_make_soft_port): set up the port buffer (shortbuf).
1279 * fports.c (local_fgetc, local_fgets): deleted.
1280 * strports.c (stgetc): likewise.

1283 * ports.h (scm_ptobfuns): add fill_buffer.
1284 * ports.c (scm_newptob): assign it.
1285 * strports.c (scm_mkstrport): set up the buffer.
1286 put just the string into the stream, not cons (pos stream).
1287 (stfill_buffer): new proc.
1289 * ports.h: fport buffer moved into port table: to be
1290 used for all port types.

1597 (scm_system_module_env_p): Assume root environment is no lookup
1600 * debug.c, eval.c, evalext.c, gdbint.c stacks.c:
1601 #include "modules.h".

1610 * error.c (scm_wta): Pass SCM_LIST1 (arg) instead of SCM_EOL to
1611 scm_misc_error when pos is a string. This allows for dispatching

1623 Most of this batch of changes is about how to deal with extended
1624 types when an object system is loaded into Guile. A nice object
1625 system is capable of representing Guile's types as class objects.
1627 For example, we want a regular expression to be of class <regex>.
1628 But regular expressions are smobs which aren't under direct
1629 control of the object system, so there has to be some mechanism
1630 which informs the object system that a new class should be created
1631 which can represent the smob type. I call this a "wrapper class".
1633 * objects.c: #include "smob.h";
1634 (scm_class_keyword): Removed. (Class is automatically created by
1636 (scm_smob_class): Array of smob classes indexed by smobnum.
1637 (scm_make_extended_class): "Plugin" function pointer for creation
1638 of wrapper classes for smob and struct types.
1639 (scm_class_of): Handle compiled closures. (Currently regarded as
1641 Use scm_smob_class to handle smob types;
1642 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1643 through scm_smob_class;
1646 * smob.c (scm_newsmob): Also create a wrapper class if
1647 scm_smob_class has been initialized.
1649 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1650 type code and smobnum.
1652 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1653 (scm_struct_table): Weak key table with auxilliary information for
1654 struct types. Currently used for names and wrapper classes.
1655 (scm_struct_ihashq): Hash function for structs.
1656 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1657 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1658 for accessing names of vtables. The record implementation in
1659 boot-9.scm currently uses the setter to record the name of record
1660 types. When the object system is initialized, it can use this
1661 information to create wrapper classes with suitable names.
1662 (scm_init_struct): Allocate scm_struct_table.
1663 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1664 (struct tags are a finite resource and we might want to restrict
1665 the use of tags to vtables only. E.g., Goops only uses tags for
1667 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1669 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1672 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1673 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1674 Used for access of struct table entries.
1676 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1677 (scm_hash_fold): New procedure. Used to process all entries in a
1678 hash table (in no particular order).
1680 Argh! For the umpteenth time I got compilation errors because of
1681 the "intuitive" name `kw'. This has to have an end:
1683 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1684 "kw" --> "keywords" everywhere.
1685 (I doubt that this will cause big compatibility problems since the
1686 application interface is unaffected.)
1688 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1690 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1692 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1693 column inums to native form.
1695 Improvement of backtraces: Introduces a new stack narrowing
1696 specifier, #t, for the inner cut. (See further in the comments in
1697 stacks.c:narrow_stack ().)
1699 * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
1700 (Used to flag certain system procedures which shouldn't turn up in
1703 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1704 modules which aren't "user" modules and the code of which

1720 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1722 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1723 procedure throughout.
1725 * print.c (scm_iprin1): Removed extraneous space when printing
1726 procedure-with-setters.
1728 Entity and operator setter slots were introduced as a complement
1729 to the <procedure-with-setter> type in order to support entities
1730 and operators with setters in a reasonable and efficient way.
1731 * procs.c (scm_procedure, scm_setter): Handle entity and operator

1747 directly through the instance.
1749 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1751 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1752 scm_struct_i_flags instead of scm_vtable_index_layout!
1754 * list.c (scm_list_star): New procedure.
1756 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1837 SYMB now point to const.
1839 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1841 * print.c (scm_iprin1): Use scm_procedure_name instead of
1842 scm_procedure_property for compiled closures.
1844 * tags.h (scm_tc7_pws): New procedure type. Four representations
1845 for procedure-with-setters were considered before selecting this
1848 1. A closure where the CODE and ENV slots are used to represent
1849 the getter and a new SETTER slot is used for the setter. The
1850 original getter is stored as a `getter' procedure property. For
1851 closure getters, the CODE and ENV slots contains a copy of the
1852 getter's CODE and ENV slots. For subr getters, the CODE contains
1855 2. A compiled closure with a call to the getter in the cclo
1856 procedure. The getter and setter are stored in slots 1 and 2.
1858 3. An entity (i.e. a struct with an associated procedure) with a
1859 call to the getter in the entity procedure and the setter stored
1860 in slot 0. The original getter is stored in slot 1.
1862 4. A new primitive procedure type supported in the evaluator. The
1863 getter and setter are stored in a GETTER and SETTER slot. A call
1864 to this procedure type results in a retrieval of the getter and a
1865 jump back to the correct eval dispatcher.
1867 Representation 4 was selected because of efficiency and
1870 Rep 1 has the advantage that there is zero penalty for closure
1871 getters, but primitive getters will get considerable overhead
1872 because the procedure-with-getter will be a closure which calls
1875 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1876 <procedure-with-setter>, but together with rep 2 it suffers from a
1877 three level dispatch for non-GOOPS getters:
1879 cclo/struct --> dispatch proc --> getter
1881 This is because the dispatch procedure must take an extra initial
1882 argument (cclo for rep 2, struct for rep 3).
1884 Rep 4 has the single disadvantage that it uses up one tc7 type
1885 code, but the plan for uniform vectors will very likely free tc7
1886 codes, so this is probably no big problem. Also note that the
1887 GETTER and SETTER slots can live directly on the heap, using the
1888 new four-word cells.
1890 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,

2073 Replaces old names serial-array-copy! and serial-array-map!.
2075 * evalext.c (map-in-order): New name. Replaces serial-map.
2077 1998-12-05 Jim Blandy <jimb@totoro.red-bean.com>
2079 * smob.c (freeprint): New function.
2080 (freecell): Use it to print freed objects, for slightly easier
2083 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2085 * backtrace.c (display_frame): Made more robust. Doesn't throw an
2086 error if no source properties can be found for a frame. (Thanks
2087 to Christian Lynbech.)
2089 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2091 * objects.h: Removed slots direct_supers and direct_slots from the
2092 definitions of the rudimentary classes described by objects.h.
2094 * objects.c, objects.h (scm_entity_p): New procedure. Together
2095 with the predicates scm_procedure_p and scm_struct_p, this
2096 predicate makes it possible to differ between structs, entities
2099 * modules.c, modules.h (scm_resolve_module): New function.
2101 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2103 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
2104 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
2107 * objects.c (scm_entity_p): New procedure.
2109 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
2110 for asubrs, rpsubrs, lsubrs and lsubr_2s.
2112 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2114 * procprop.h (scm_i_procedure_arity): Added declaration.
2116 * procprop.c (scm_i_procedure_arity): Made global; New code to
2117 handle operators and entities.
2118 (scm_procedure_property): No need to call scm_procedure_p since
2119 scm_i_procedure_arity now does all necessary type checking.
2120 Added #include "objects.h".
2122 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2123 s_add_hook_x --> s_remove_hook_x.
2124 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
2125 Added #include "procprop.h"
2127 * feature.c, feature.h (scm_reset_hook_x): New procedure.
2128 (scm_make_hook): Optional argument defines number of arguments to
2130 (scm_make_named_hook): Take number of args as second arg.
2131 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2132 boot-9.scm for a while); First arg is the hook. The rest are
2133 arguments passed on to the hook procedures.
2135 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
2137 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2138 scm_logbit_p): Do the computation in ulongs. This is not as nice
2139 as doing it in bignums, but at least it's good enough for
2140 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2142 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2143 subexpressions. (Thanks to Charbel Jacquin.)
2145 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
2147 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
2148 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2149 (scm_make_named_hook): New function.
2151 * feature.c: Added #include "eval.h".
2153 * modules.c (scm_make_module): Beautify the module.
2155 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2157 * modules.c, modules.h: New files: C interface to modules. (This
2158 is necessary in order to interface the object system to Guile
2159 properly. The guts of these modules will be replaced by the new
2160 module system in the future.)
2162 * init.c: Added #include "modules.h"
2163 (scm_boot_guile_1): Call scm_init_modules.
2164 (invoke_main_func): Call scm_post_boot_init_modules.
2166 * Makefile.am: Added modules.c, modules.x, modules.h.
2168 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
2170 * procs.c: #include "objects.h"
2171 (scm_procedure_p): Return #t also on structs which are operators.
2173 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
2174 <operator-metaclass> and <entity-class> to <standard-class>,
2175 <operator-class> and <entity> in order to conform with STKlos
2178 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
2179 which isn't an operator.
2180 (SCM_APPLY): Ditto, but jump to badproc.
2182 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
2184 * eval.c (SCM_CEVAL): Allow structs implanted in code.
2185 Previously, structs implanted in code were interpreted as forms
2186 the operator of which was a gloc. We solve this by checking for
2187 the zero in the emulated vcell in the struct vtable. Since
2188 implanted structs always will look like forms with a gloc
2189 operator, execution will only be slowed down by maximally one
2190 extra test-and-branch per application.
2192 * evalext.c (scm_definedp): Removed check for isyms; Added a
2193 second optional argument: It is now possible to supply an
2194 evaluation environment in which to look for the symbol.
2196 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2198 * readline.c (scm_init_readline): Set
2199 rl_basic_word_break_characters. (Thanks to Ian Grant.)
2201 * coop.c (coop_condition_variable_wait): Removed
2202 (coop_condition_variable_wait_mutex): Folded logic of
2203 coop_mutex_unlock into coop_condition_variable_wait_mutex to
2204 prevent condvar signal lossage. Previously, another thread could
2205 start to run after unlocking the mutex but before putting the
2206 current thread on the wait queue. If that thread then would
2207 signal the first, the signal would be lost. (Thanks to Christian
2210 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2212 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
2215 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2217 * objects.c (scm_i_make_class_object): Renamed from
2218 make_class_object; exported; error checking moved to
2219 scm_make_class_object and scm_make_subclass_object.
2220 (scm_make_class_object, scm_make_subclass_object): Use
2221 scm_i_make_class_object.
2222 (scm_make_subclass_object): Let the subclass have same metaclass
2225 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2227 * debug.c (scm_debug_options): Bugfix: Set the value of
2228 scm_stack_checking_enabled_p after setting debug options;
2229 #include "stackchk.h". (Thanks to Richard Polton.)
2231 1998-11-13 Radey Shouman <rshouman@metro2000.com>
2233 * unif.c (scm_array_contents): removed unnecessary test for 0
2236 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2238 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
2239 Replaced by macro `collect' in boot-9.scm.
2241 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2243 * eval.c (scm_copy_tree): Copy source properties if existent.
2245 * debug.c (scm_start_stack): Copy source when evaluating. (If we
2246 don't, we may end up passing memoized source to a transformer.)
2248 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2250 * stack.c (get_applybody): Help function which lookups the first
2251 body form of the apply closure.
2252 (read_frames): Prevent the source of the first form of the apply
2253 closure from being recorded. This would only be confusing.
2255 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
2256 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
2258 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
2260 * stacks.c (read_frame): Bugfix: Removed lingering `else'
2262 (read_frames): Use SCM_MACROEXPP.
2264 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2266 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
2267 don't contain interesting information since all arguments are
2268 present in the frame which applies the compiled closure anyway.);
2269 Skip the transformer application frames.
2271 * print.c (scm_iprin1): Print gsubrs as primitives.
2273 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2275 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
2277 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
2278 that we can identify these in a backtrace. (This change doesn't
2279 introduce any significant speed penalty.)
2281 * eval.c: Added note about `serial-map' using scm_map.
2283 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2284 readline options. They should reside in their own options array.
2286 * readline.c, readline.h (scm_readline_options,
2287 scm_readline_opts): Moved readline options here.
2289 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2291 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2292 SCM_ROCHARS instead of SCM_CHARS.
2294 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2295 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2297 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2299 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2300 This is quite important since the latter clears the
2301 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2302 every single character read...
2304 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2306 * print.c (scm_iprin1): Removed suspect looking (and indeed
2307 malevolent) semicolon after test for user supplied closure print
2308 procedure. (Thanks to Telford Tendys.)
2310 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2311 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2312 starting to search the list. Removed call to sloppy_mem_check.
2314 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2315 procedures: Same as scm_delq_x et al, but delete maximally one
2318 * options.c (scm_options, scm_init_options): GC-protect option
2319 values of type SCM. (Thanks to Telford Tendys.)
2321 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2323 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2324 make sure that there always is a "real" scm_lookupcar.
2326 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2328 * read.c, read.h (scm_read_opts): New read options
2329 "history-length" and "history-file".
2330 (scm_read_options): Stifle history to history length.
2332 * readline.c (scm_read_history, scm_write_history): New procedures.
2334 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2336 * eval.h (scm_macro_eval_x): Removed declaration.
2338 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2339 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2340 Renamed and made global.
2342 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2343 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2345 * evalext.c, evalext.h: New files. Contain non-R5RS things
2346 having to do with evaluation.
2348 * evalext.c (scm_serial_map): New procedure: Version of `map'
2349 which guarantees that the procedure is applied to the lists in
2351 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2352 returns a list of the results of the body forms instead of the
2353 result of the last body form.
2354 (scm_definedp, scm_m_undefine): Moved from eval.c
2356 * evalext.h (scm_m_sequence_to_list): Added declaration.
2358 * macros.c, macros.h: New files.
2359 (scm_procedure_to_syntax, scm_procedure_to_macro,
2360 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2361 scm_macro_name, scm_macro_transformer): Moved from eval.c
2362 (scm_make_synt): Moved from eval.c
2364 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2366 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2369 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2371 * debug.c, print.c: Added #include "macros.h".
2373 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2375 This change adds the ability to use `unread-char' multiple times
2376 without interspersed reads and adds the new procedure
2377 `unread-string'. The change is optimized for the common case of
2378 unreading a single character. This is also the reason behind the
2379 choice to store characters in the port itself: in most cases no
2380 extra malloc is required.
2382 The amount of code in some macros in ports.h has been increased to
2383 the extent that they would fit better as C functions, but, since
2384 this code belongs to the port representation, such functions
2385 should be placed in ports.c which would cause calls back and forth
2386 between ports.c and genio.c. That is not good for performance.
2387 Also, keeping them as macros allows the compiler to do some
2388 optimizations which are needed to make the current interface
2389 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2391 One benchmark (Guile startup time) indicates an increase of
2392 loading speed of 1%. Another (reading (using `read') boot-9.scm
2393 10 times) shows no change in performance.
2395 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2396 made to find a beautiful solution.)
2398 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2399 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2400 character. (SCM_CLRDY clears all.)
2401 (SCM_N_READY_CHARS): New macro: Returns number of unread
2402 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2403 (struct scm_port_table): New fields: `entry' contains port table
2404 index, `cp' points to last unread char, `cbuf' is the buffer for
2405 unread chars, `cbufend' points after end of the character buffer.
2407 * ports.h, ports.c (scm_unread_string): New procedure.
2408 (scm_grow_port_cbuf): New function.
2410 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2412 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2413 to read unread characters. Use SCM_TRY_CLRDY instead of
2416 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2418 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2420 * genio.c, genio.h (scm_ungets): New function.
2422 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2425 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2427 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2428 declarations. (Thanks to Russ McManus.)
2430 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2432 * numbers.c (num2long): As a software archeologist, I'm proud of
2433 this finding! :) Preliminary dating suggests an almost 4 year old
2434 remnant from the SCM ancestor. The sample has been removed from
2435 the finding site and is now safely stored in the repository.
2437 * numbers.h: Removed prototype for num2long.
2439 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2441 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2442 array as second arg.
2443 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2444 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2445 * gh.h: Updated and added prototypes.
2447 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2449 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2451 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2453 * guile-snarf.in: Never generate an empty file. (Thanks to
2456 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2457 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2458 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2459 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2460 gh_new_procedure5_0): Specify argument types, to appease C++
2461 compilers. (Thanks to Brad Bowman.)
2463 Bug reports from Russ McManus:
2464 * guile-snarf.in: If the CPP environment variable is set, use that
2465 as the C preprocessor, instead of the preprocessor autoconf
2467 * snarf.h (SCM_PROC): Cast the function pointer passed to
2468 scm_make_gsubr, to satisfy C++.
2470 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2471 Use the handler passed, instead of ignoring it and using
2472 gh_standard_handler. (Thanks to Etienne Bernard.)
2474 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2476 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2479 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>

2496 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
2499 * script.c (scm_compile_shell_switches): Define
2500 use-emacs-interface in the root module, so the repl code can see
2501 it. See today's change to top-repl in ice-9/boot-9.scm.
2503 * filesys.c (set_element, get_element): Make sure that `element'
2504 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2505 Boekemeier and Jorgen "forcer" Schaefer.)
2507 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2509 * chars.c (scm_charnames): In ASCII character name table, make
2510 newlines print as #\newline by default, not #\nl.
2512 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2513 alphabetical order. Oh thrills. But it helps me know how far
2514 along in the compilation I am.
2515 * Makefile.in: Regenerated.
2517 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2519 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2520 #bytes(...) to #y(...), and syntax for short vectors from
2521 #short(...) to #h(...). This may seem nutty, but, like the other
2522 uniform vectors, byte vectors and short vectors want to have the
2523 same print and read syntax (and, more basic, want to have read
2524 syntax!). Changing the read syntax to use multiple characters
2525 after the hash sign breaks with the conventions used in R5RS and
2526 the conventions used for the other uniform vectors. It also
2527 introduces complexity in the current reader, both on the C and
2528 Scheme levels. (The Right solution is probably to change the
2529 syntax and prototypes for uniform vectors entirely.)
2531 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2533 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2534 (Thanks to Jorgen "forcer" Schaefer.)
2535 * ports.h (SCM_NOFTELL): New flag.
2536 * fports.c (local_fgets): If it's set, use the generic fgets.
2537 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2539 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2541 * script.c (scm_compile_shell_switches): Add handling of -q switch
2542 (inhibit loading of user init file).
2543 (scm_shell_usage): Add usage text for -q switch.
2544 (scm_compile_shell_switches): Always load user init file first if
2545 it is loaded at all.
2547 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2549 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2550 and is now broken under NetBSD. I can't fathom what it's trying
2551 to do, so I've replaced it with something that I do understand,
2552 which seems to work, and which isn't broken on NetBSD. "Progress?
2553 You Decide." (Thanks to Perry Metzger.)
2555 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2556 signed/unsigned comparison.
2558 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2560 Warning fixes from Greg Harvey:
2561 * unif.c (scm_array_set_x): initializer for pos
2562 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2563 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2564 initializers for field_type, since EGCS so desparately wants to
2566 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2567 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2568 when GUILE_DEBUG is defined.
2569 * dynwind.h (scm_wind_chain): Same.
2570 * ports.h (scm_pt_size, scm_pt_member): Same.
2571 * print.h (scm_current_pstate): Same.
2572 * procs.h (scm_make_cclo): Same.
2574 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2576 Handle short and long long uniform arrays properly. (Thanks to
2578 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2579 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2580 scm_tc7_llvect (long long vectors).
2582 Change the way libguile and boot-9.scm are timestamped, to try to
2583 get rid of these spurious mismatch warnings. Now both
2584 libguile/versiondat.h and ice-9/version.scm are generated directly
2585 by the configuration process, rather than having version.scm
2586 generated directly, and libguile/versiondat.h generated by the
2587 Makefile, which is generated by configure. It seems that
2588 sometimes the Makefile would change, but versiondat.h depends on
2589 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2590 * Makefile.am (versiondat.h): Target removed; this is generated
2591 directly by the configure script now.
2592 (BUILT_SOURCES): Remove versiondat.h.
2593 * versiondat.h.in: New file, transformed by the configure script
2595 * Makefile.in: Regenerated.
2597 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2598 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2599 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2600 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2601 if we want to use them in a header file some day, we can. (Thanks
2602 to Michael Livshin.)
2604 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2605 SCM numbers, so we won't have rollover problems; the range of a
2606 signed long in milliseconds is about 25 days. (Thanks to Karl
2609 Don't redefine sleep and usleep; fix this problem now.
2610 * coop.c (sleep, usleep): Remove declarations; we don't use or
2611 redefine these any more.
2612 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2613 job of usleep and sleep in a thread-friendly way. We can use
2614 these in the rest of Guile. Define versions for systems both with
2615 and without iselect.
2616 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2617 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2618 we're just using it, not redefining it, we can use a K&R style
2620 (sleep): Declare this, too, if the system hasn't.
2621 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2622 scm_uthread_sleep if they're available; otherwise, just call the
2624 * scmconfig.h.in: Regenerated.
2626 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2628 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2630 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2632 * threads.c: Doc fix.
2634 The argument type of usleep varies from system to system,
2635 as does the return type. We really shouldn't be redefining usleep
2636 at all, but I don't have time to clean that up before the 1.3.
2637 release. It's on the schedule for afterwards. (Thanks to Julian
2639 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2641 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2642 * scmconfig.h: Regenerated.
2644 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2645 right way to handle system variation. Autoconf's approach is the
2647 * simpos.h (scm_software_type): Declaration deleted.
2649 * script.c (scm_find_executable): Don't test if unix is #defined
2650 here; first, NetBSD doesn't #define it, and second, it's the wrong
2651 way to go about these things. (Thanks to Perry Metzger.)
2652 (dld_find_executable): Delete this MSDOS support code. This isn't
2653 the way we want to support this; it needs to be rethunk at a
2656 * genio.c (scm_do_read_line): Don't just politely check that the
2657 line was either non-empty or EOF. Abort if it's empty and not
2660 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2662 * scmconfig.h.in: Regenerated.
2664 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2667 * genio.c (scm_do_read_line): Count lines correctly when the file
2668 doesn't end in a newline.
2670 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2672 * genio.c (scm_do_read_line): Maintain the line count correctly.
2673 (Thanks to Harvey J. Stein and Greg Harvey.)
2675 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2678 * numbers.c (big2str): Protect t from garbage collection until
2679 we're done. (Thanks to Gary Houston.)
2681 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2683 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2685 * Makefile.in: Regenerated.
2687 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2688 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2691 Do magic to mix reads and writes on stdio FILE-based ports.
2692 (Thanks to Christian Lynbech.)
2693 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2695 (pre_read, pre_write): New functions.
2696 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2697 local_fputs): Call them.
2698 (local_fflush): Mark the port as ready for reading and writing.
2699 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2700 flags on new port objects. This might not be accurate --- who
2701 knows what state the FILE * is in when we get it --- but it won't
2702 do extraneous calls to fflush or fseek, so it's no worse than the
2703 behavior before this change.
2704 * ports.h: Add comment.
2706 Centralize the creation of port objects based on stdio FILE * in
2707 fports.c; don't just throw them together anywhere.
2708 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2709 what the rest of Guile wants. Don't set the revealed count;
2710 that's only appropriate for stdin, stdout, stderr.
2711 (scm_standard_stream_to_port): This function does set the revealed
2713 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2714 not scm_stdio_to_port.
2715 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2716 * fports.c (scm_open_file): Same.
2717 * posix.c (scm_pipe): Same.
2718 * socket.c (scm_sock_fd_to_port): Same.
2719 * ioext.c (scm_fdopen): Same.
2720 (scm_freopen): Moved from here to...
2721 * fports.c (scm_freopen): ... here. This is really something that
2722 munges the internals of an fport, so it should go here.
2723 * fports.h (scm_stdio_to_port): Adjust prototype.
2724 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2725 * ioext.h (scm_freopen): Prototype removed.
2727 * filesys.c (set_element, get_element): This can work on both pipe
2728 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2731 * scmconfig.h.in: Regenerated.
2733 Change the definition of the functions in scm_ptobfuns so that
2734 they get passed the port object, not the port's stream.
2735 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2736 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2737 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2738 Pass the port itself to the scm_ptobs function.
2739 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2740 scm_generic_fgets): Same.
2741 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2742 getc_void_port, fgets_void_port, close_void_port): Just change the
2743 argument names; these functions don't really do anything.
2744 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2745 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2746 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2747 Also, use prototyped definitions, and get rid of the extra
2749 (scm_fptob, scm_pipob): We don't need casts here any more.
2750 * strports.c (prinstpt): Use prototype declarations.
2751 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2752 and use SCM_STREAM to get the string info. Also, use prototyped
2753 definitions, and get rid of the extra declarations.
2754 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2757 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2758 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2760 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2761 scm_fgets, for consistency.
2762 (scm_fptop, scm_pipob): References updated.
2764 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2766 Include the source location in error messages for scripts.
2767 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2768 stack is still there when we catch the error.
2769 * throw.c (handler_message): If we are handling an error with a
2770 message, then put together the proper arguments and call
2771 scm_display_error, instead of scm_display_error_message. That
2772 displays source location, if it can find it.
2774 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2776 * gc.c (scm_unprotect_object): Change this so that calls to
2777 scm_protect_object and scm_unprotect_object nest properly.
2778 (scm_protect_object): Doc fixes.
2780 * strings.c (scm_string_set_x): Require the argument to be a
2781 writable string, not a substring or a symbol.
2782 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2783 (Thanks to John Redford and Charbel Jacquin.)
2785 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2787 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2789 * eval.c (safe_setjmp): Remove this misunderstanding.
2790 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2793 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2795 * libguile.h: Mark these as C declarations, for compilation by C++
2798 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2799 __cplusplus clause. I seriously doubt this ever worked the way
2800 the author seems to have intended.
2802 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2804 Utterly needless cleanups to hopelessly messy code.
2805 * ports.c: Doc fixes.
2806 (scm_fflush): Moved to ...
2807 * genio.c (scm_fflush): ... here, amongst all the other port
2808 method invocation functions.
2809 * genio.h, ports.h: The prototype moves too.
2811 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2813 * backtrace.c (display_error_body): The current frame does not
2814 always have a parent frame; consider a function called directly
2815 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2818 * alloca.c (alloca): Undo yesterday's changes, and simply call
2819 malloc directly for storage, and abort if we don't get what we
2820 want. The situation is much simpler --- just call malloc. Emacs
2821 has bizarre/evil requirements (signal handlers might malloc unless
2822 you set this global flag, so you have to set the flag around all
2823 calls to malloc) which we are certainly not going to conform to,
2824 so we can do the simple and obvious thing.
2826 * coop.c (coop_condition_variable_wait): Make this function
2827 static. It's only useful internally --- you should never just
2828 wait on a condition variable.
2829 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2831 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2833 * unif.c (scm_array_set_x): Accept any kind of number as an
2834 element for a uniform vector of doubles. This is more consistent
2835 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2837 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2838 works; I can't conveniently test it myself. (Thanks to Dvid
2839 Tillman for the bug report.)
2841 * init.c: Doc fixes.
2843 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2844 from here, not from scm_compile_shell_switches (which is a pretty
2845 dumb place to do it).
2846 (scm_load_startup_files): New function.
2847 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2848 * script.c (scm_compile_shell_switches): Don't load the startup
2850 (scm_ice_9_already_loaded): Variable moved.
2851 * init.c (scm_load_startup_files): Prototype for new function.
2852 * gh_init.c (gh_enter): Doc fix.
2854 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2856 Some anti-warning changes from Greg Harvey.
2857 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2858 warnings when it doesn't understand our NORETURN declarations in
2860 * posix.c (scm_mknod): Similar.
2862 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2864 * posix.c (scm_getpwuid): If we can't find an entry, return our
2865 own message, instead of using scm_syserror --- the getpwMUMBLE
2866 functions don't set `errno' to anything interesting.
2868 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2870 Get rid of warnings from the cooperative threading system.
2871 * threads.h (scm_single_thread_p, scm_yield,
2872 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2873 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2874 scm_wait_condition_variable, scm_signal_condition_variable): Add
2875 prototypes for these Scheme-visible functions.
2876 * coop-defs.h (coop_next_runnable_thread,
2877 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2878 Prototypes for these here, even though they're from iselect.c.
2879 (coop_condition_variable_wait, coop_join): Add prototypes.
2880 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2881 scm_threads_free_condvar): Make these smob functions static.
2882 * coop-threads.h (coop_init): Give this a real prototype.
2883 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2884 (coop_next_runnable_thread): No need to provide prototype; it's in
2887 * scmconfig.h.in: .detarenegeR
2889 * iselect.c, threads.c: Doc fixes.
2891 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2893 * Makefile.in: Regenerated with a patched automake, to get
2894 dependency generation right when using EGCS.
2896 * inet_aton.c (inet_aton): Add prototype, to remove compiler
2897 warning. (Thanks to Robert Pluim.)
2899 * inet_aton.c (inet_aton): Reassure the compiler that the
2900 arguments to the <ctype.h> macros are all unsigned characters, not
2903 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2905 Getting rid of more warnings...
2906 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
2907 today's change to ../configure.in.
2908 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
2909 * scmconfig.h.in: Regenertaded.de.,.__
2910 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
2911 (scm_localtime, scm_mktime): Use a const char * to manipulate the
2914 * readline.c: Doc fix.
2915 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
2916 * readline.h (scm_filename_completion_function): Add prototype.
2917 (scm_init_readline): Make this into a prototype.
2919 * readline.c (scm_filename_completion_function): Use SCM_PROC to
2920 declare this, instead of calling scm_make_subr manually.
2922 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
2924 * readline.h (scm_init_readline): Add prototype for this.
2925 (scm_init_readline): Make this a real prototype.
2927 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
2929 Warning fixes from Maciej Stachowiak:
2930 * backtrace.h (scm_display_application, scm_backtrace): Add
2932 * debug.c (scm_m_start_stack): Make this function static.
2933 * fluids.h (scm_fluid_p): Add prototype.
2934 * procprop.c (scm_i_procedure_arity): Make this function static.
2935 * regex-posix.c (scm_regexp_error_msg): Make this function static.
2936 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
2937 * root.h (scm_dynamic_root): Add external prototype.
2938 * scmsigs.h (scm_usleep): Add external prototype.
2939 * script.h (scm_init_script): Use prototype, not K&R decl.
2940 * stacks.h (scm_stack_id): Add external prototype.
2941 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
2943 1998-09-30 Mark Galassi <rosalia@cygnus.com>
2945 * gh.h: took out the definitions of vset and vref, since they are
2946 replaced by the proper vector routines that correspond to the R4RS
2949 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
2951 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
2952 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
2953 third argument, a C expression that should result in a SCM value,
2954 which is used to initialize the variable. Reimplemented
2955 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
2958 * version.h (scm_libguile_config_stamp): Add prototype.
2959 (From Maciej Stachowiak.)
2961 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
2963 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
2964 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
2966 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
2968 * print.c (scm_iprin1): Rather than having one i, and using it in
2969 several places, declare a fresh i local to each block where it is
2970 used, and give it a signedness appropriate to its use in each case.
2971 (scm_iprlist): Same.
2973 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
2974 comparison warnings.
2976 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
2977 signed/unsigned clashes.
2979 * posix.h (scm_tmpnam): Added prototype.
2981 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
2982 scm_make_subclass_object): Add external prototypes.
2984 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
2985 comparison is okay here.
2987 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
2989 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
2990 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
2992 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
2995 * load.c (swap_port): Make this function static.
2997 * load.c (scm_search_path): Make max_path_len and max_ext_len
2998 unsigned, since they're compared against string sizes.
3000 * load.c (init_build_info): Make i unsigned.
3002 * ioext.h (scm_read_line): Add prototype.
3004 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3005 scm_hash_fn_remove_x): Make hash bucket index local variable k
3006 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3007 accurately as possible.
3009 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3010 comparisons, and range checking to make sure those casts are
3013 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3014 signed/unsigned comparisons.
3016 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3017 avoid signed/unsigned comparisons.
3018 * smob.h (scm_numsmob): Change extern declaration to match.
3020 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3021 avoid signed/unsigned comparisons.
3022 * ports.h (scm_numptob): Change extern declaration to match.
3023 (scm_current_load_port, scm_set_port_line_x,
3024 scm_set_port_column_x): New prototypes.
3026 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3027 test code, and it causes warnings.
3029 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3030 gh_uniform_vector_ref): Added prototypes.
3032 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3033 debugging support unconditionally. That's backtrace.c, stack.c,
3034 debug.c, and srcprop.c.
3035 (EXTRA_libguile_la_SOURCES): Omit those from here.
3036 * Makefile.in: Regenerated.
3038 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3040 * options.c (scm_options): Bugfix: Allow empty list of options!
3042 * debug.c, debug.h (scm_single_step): Removed.
3043 (scm_with_traps): New procedure. This procedure could easily be
3044 written in Scheme but needs to be highly optimized.
3046 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3048 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3049 Check SCM_TRAPS_P before trapping.
3051 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3053 Changes to avoid signed/unsigned comparison warnings.
3054 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3055 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3056 so they can have appropriate types for each application. Make i
3057 signed. Use initializers in some spots. I'll probably pay for
3059 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3060 (scm_must_realloc): Make nm unsigned.
3061 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3062 (scm_init_storage): Use prototype-style definition, and make the
3064 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3065 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3067 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3068 avoid signed/unsigned comparison warnings, and because the return
3069 value of readlink may be -1. Don't bother casting the third
3070 argument to readlink.
3072 * filesys.c (scm_dirname, scm_basename): Move these to their own
3073 page, at the end of the file.
3074 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3076 * eval.h (scm_eval_options_interface): Add external prototype for this.
3077 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3079 * eval.c (scm_lookupcar1): Make this static.
3081 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3082 Make these prototype declarations, not K&R-style.
3084 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3085 unsigned comparison warning.
3087 * appinit.c: File removed. It had a single function in it, empty,
3088 whose reason for existence is explained in no documentation or
3089 comment. I think it's there as a default for some Tcl-style
3090 initialization, but Tcl abandoned that approach a while ago.
3091 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3092 (BUILT_SOURCES): Remove appinit.x.
3093 * Makefile.in: Regenerated.
3095 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3097 * Makefile.in: Regenerated using the last public version of
3098 automake, not the hacked Cygnus version.
3100 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3102 Remove Totoro kludge.
3103 * Makefile.in, scmconfig.h.in: Regenerated.
3104 * init.c, readline.c: Don't check if TOTORO is #defined.
3106 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3108 * Makefile.am: Adjust for new thread configuration system.
3109 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3110 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3112 (THREAD_LIBS): Definition deleted; automake will generate such
3113 things automatically.
3114 * Makefile.in: Regenerated.
3116 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3118 Simplify smob and port marking; set the mark bit in the generic
3119 marking code, and make marker routines only responsible for
3120 turning up outgoing pointers.
3121 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3122 before calling the marking function. Don't call the marking
3123 function if it's zero.
3124 * markers.c (scm_mark0): Just return #f. This function isn't
3125 necessary at all now, but it's harmless to call it. We'll leave
3126 it in so other folks' code doesn't croak at link time.
3127 (scm_markcdr): Don't call SCM_SETGC8MARK.
3128 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3129 * dynl.c (mark_dynl_obj): Same.
3130 * root.c (mark_root): Same.
3131 * srcprop.c (marksrcprops): Same.
3132 * unif.c (markra): Same.
3133 * variable.c (scm_markvar): Same.
3134 * ports.c (scm_markstream): Same.
3135 (void_port_ptob): Specify zero for our marking function.
3136 * debug.c (debugobjsmob): Same.
3137 * dynwind.c (guardsmob): Same.
3138 * filesys.c (dir_smob): Same.
3139 * fluids.c (fluid_smob): Same.
3140 * fports.c (scm_fptob, scm_pipob): Same.
3141 * mallocs.c (mallocsmob): Same.
3142 * regex-posix.c (regex_t_smob): Same.
3143 * smob.c (freecell, flob, bigob): Same.
3144 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3145 * throw.c (jbsmob, lazy_catch_funs): Same.
3147 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3149 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3150 scm_copy_tree on code in order not to let memoized code to leak
3151 out. Thus, scm_copy_tree needs to copy vectors as well since
3152 quasiquote can introduce evaluated code also inside vector
3155 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3157 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3159 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3160 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3163 * unif.c: Say that ivect and uvect are of type signed and unsigned
3164 long instead of int in commentary so that it correctly describes
3167 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3169 * stime.c: Removed declaration of strptime. (It should be
3170 declared by the system headers. If it turns out that some systems
3171 don't, we'll handle that then.) (Thanks to Greg Troxel.)
3173 * stime.h: Renamed TIMEH --> STIMEH
3175 * backtrace.c (scm_display_error, scm_display_backtrace): In order
3176 to increase portability, don't use structure assignment.
3177 (Thanks to Nicolas Neuss.)
3179 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
3181 (finalize_fd_sets): Added empty statement after last case label.
3182 (Thanks to Nicolas Neuss.)
3184 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
3187 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
3189 * init.c, readline.c: OK, I won't have these readline.x bug
3190 reports anymore. We've had them since April. The current reason
3191 is a completely unintelligible failure of totoro.red-bean.com to
3192 do the test for rl_getc_function in libreadline correctly. This
3193 kludge overrides the test if we're on totoro so that the snapshot
3194 generation process can work.
3196 * readline.c: Define a strdup replacement if not existent on system.
3198 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3200 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
3201 This change makes scm_make_vector R5RS compatible. We cannot keep
3202 the third argument since people want to be able to deduce the form
3203 of the C function call only by looking at R5RS. (At the same time
3204 we have removed some unnecessary complexity!)
3206 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
3207 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
3208 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
3209 argument in call to scm_make_vector.
3211 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3213 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
3214 This macro is useful in applications.
3216 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3218 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
3219 (scm_parse_path, scm_search_path): New Scheme level procedures.
3221 * load.h (scm_internal_parse_path, scm_parse_path,
3222 scm_search_path): Declared.
3224 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3226 * filesys.c (dirname, basename): New procedures.
3228 * init.c (scm_boot_guile_1): Removed condition around
3231 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
3232 new data type (guards) for representation of C level guards and
3233 data on the wind chain.
3234 (scm_internal_dynamic_wind): New function.
3236 * dynwind.h: Declare scm_internal_dynamic_wind.
3238 * root.h (scm_root_state): Added scm_cur_loadp.
3240 * root.c (mark_root): Added comment about cur_loadp.
3242 * load.c: #include "dynwind.h";
3243 (scm_primitive_load): Use scm_inner_dynamic_wind to update
3246 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
3248 * ports.c (current-load-port): New procedure.
3250 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3252 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
3253 not a tty, return #f.
3255 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
3256 to Julian Satchell and Roland Kaufmann.)
3258 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
3259 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
3261 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3263 * debug.h, debug.c (scm_start_stack): New function. Implements
3264 the guts of old scm_m_start_stack.
3266 * debug.c (scm_m_start_stack): Use scm_start_stack.
3268 * init.c (scm_start_stack, scm_restart_stack): Renamed to
3269 start_stack and restart_stack. (These have static scope.)
3271 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3273 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
3274 readline functions to come in release 2.3. (Thanks to Chet
3276 (handle_errors): Use the above functions.
3278 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3280 * readline.c: Improvements for readline support: Handle errors
3281 better; Implement before-read-hook.
3283 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3285 * init.c (scm_boot_guile_1), readline.c: Test for
3286 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3287 assure that we have version >= 2.1.)
3289 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3291 * readline.c (scm_readline): Defer interrupts while we're calling
3294 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3295 away the string to add_history.
3296 (completion_function): Do completion for readline. (Thanks to
3298 (scm_filename_completion_function): New procedure: Filename
3300 (current_input_getc): New function. Use this one instead of
3301 standard getc from readline.
3303 * throw.c, throw.h (scm_handle_by_throw): New function: This
3304 handler throws errors to next handler on the dynwind chain.
3306 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3308 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3311 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3313 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3315 (scm_procedure_properties): Modified to return arity together with
3317 (scm_procedure_property): Added the read-only property `arity'.
3318 (scm_set_procedure_property_x): It is an error to set the `arity'
3321 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3322 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3324 * procprop.h (scm_sym_arity): New symbol.
3326 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3327 to set the dispatch procedure of an operator or entity object.
3329 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3330 Made procedure slots read-only.
3332 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3333 scm_tcs_cons_gloc case in zero args switch; Fixed args
3334 construction for operators in scm_tcs_cons_gloc case in two args
3337 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3339 * fluids.c: Removed use of assert.h (in order to avoid
3342 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3344 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3346 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3347 change makes the evaluator safer at the cost of evaluation speed.
3348 It handles the case when the user has added a non-immediate
3349 improper end of the application form, e.g., `(+ 0 . x)'.
3350 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3351 minimize the extra cost as much as possible. The new code is
3352 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3353 problem with structs planted directly in the code (e.g. by a
3354 macro). This no longer causes segmentation fault. (Thanks to
3357 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3358 arg `proc' in order to be able to throw errors; New argument
3361 * Removed extra #include "debug.h"
3363 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3365 * scmsigs.c: Declare usleep as returning void on some systems.
3366 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3369 * coop.c (usleep): Return void on some systems.
3371 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3373 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3375 * coop.c: Changed return type of usleep to int.
3377 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3378 isn't found in the OS.
3380 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3381 isn't enabled. (Thought that I had made this change ages ago...)
3383 * iselect.c: Declare bzero if not defined by OS.
3385 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3387 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3388 condition. (Thanks to John Tobey.)
3390 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3391 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3394 * __scm.h: Start the long-term project of moving to POSIX threads.
3395 Phase 1: Classification of all critical sections.
3396 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3397 for A sections. (See comments in __scm.h for details.)
3399 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3400 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3402 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3404 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3405 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3406 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3407 dependencies on $(srcdir)/Makefile.in
3408 $(top_builddir)/config.status in order to avoid circularity.
3410 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3411 from argc if argc was 0 initially.
3413 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3414 in generation of libpath.h.
3416 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3418 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3419 libguile from 2 to 3.
3421 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3423 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3425 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3427 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3428 scm_set_port_column_x, scm_port_filename,
3429 scm_set_port_filename_x): Removed optional arguments. Added
3430 proper argument checking.
3432 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3433 stack size in machine words.
3435 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3436 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3437 to Ole Myren Röhne.)
3439 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3441 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3442 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3444 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3447 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3448 procedure apply: Copy argument lists before pushing them unto the
3449 environment so that the environment won't get mutated due to
3450 manipulation of procedure arguments. This should perhaps be
3451 regarded as a temporary solution until someone finds a more
3452 efficient one. (Thanks to Maciej Stachowiak.)
3454 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3456 * script.c (scm_compile_shell_switches): Use "guile" as default
3457 zero arg if argc is NULL.
3459 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3461 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3462 is zero. (Thanks to Dirk Herrmann.)
3464 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3466 * ports.c (scm_add_to_port_table): First line is now line 0
3467 (was 1). (Interface changed according to suggestion by Per
3470 * backtrace.c (display_header): Add 1 to line and column numbers
3471 when presenting them to the user.
3473 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3474 from debug.c --> eval.c
3476 * eval.h, eval.c (scm_eval_options_interface): New options
3478 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3479 i.e. stacks for new threads.
3481 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3483 * eval.c (unsafe_setjmp): Removed with #if 0.
3485 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3488 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3489 to avoid compiler warnings.
3491 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3493 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3495 * throw.c (handler_message): Print message on current error port
3496 instead of default error port. (Thanks to Maciej Stachowiak.)
3498 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3500 * ports.c (scm_add_to_port_table): allocate in units of
3501 struct scm_port_table *, not struct scm_port_table.
3502 * posix.c (scm_close_pipe): remove the port from the port table
3504 Thanks to Rob Engle for both fixes.
3506 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3508 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3509 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3511 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3513 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3515 * backtrace.c (display_error_body, display_backtrace_body),
3516 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3517 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3518 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3519 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3522 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3523 don't receive the jmpbuf arg anylonger.
3524 (scm_catch): Don't accept a #f tag.
3525 (scm_throw): Check that key is a symbol.
3526 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3528 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3530 * async.c (async_pending): Removed declaration.
3532 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3534 * dynwind.c (scm_wind_chain): New debug function.
3536 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3537 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3538 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3539 extra layer of functions around the body and handler of a thread.
3540 This extra layer makes sure that the handler is called in the
3541 dynamic context of the surround (= empty dynwind list), but under
3542 the *dynamic root* of the body. We can not use the dynamic root
3543 of the surround since that root belongs to another thread => stack
3544 is not handled correctly. It may seem ugly to use this extra
3545 layer, but the extra cost in terms of execution time is really
3546 negligible compared to the total amount of time required to create
3547 a thread, and it would reduce maintainability to duplicate the
3548 crucial and complicated steps performed by cwdr.
3550 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3551 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3552 get re-enabled. The important effect of this is that interrupts
3553 are blocked during thread switching so that thread data structures
3554 don't risk getting messed up by an unfortunate signal.
3555 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3556 seems to do more aggressive optimization which actually move
3557 instructions around in these macros in a fatal way. Therefore:
3558 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3559 just superstitious...)
3560 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3561 This macro should be used instead of SCM_ASYNC_TICK since the
3562 latter doesn't do context switches any more.
3564 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3565 instead of SCM_ASYNC_TICK.
3567 * coop.c, iselect.c: Since thread switches are now performed with
3568 interrupts masked, we can't use the old mechanism of delivering
3569 signals immediately when they arrive. Signals must instead be
3570 delivered when the asyncs run *after* the end of the critical
3571 section in scm_internal_select. But this also means after context
3572 switch so that the signal will be delivered to a different thread.
3573 To avoid this, I have changed the protocol of
3574 coop_wait_for_runnable_thread and friends so that they are allowed
3575 to return the original thread. So, if a signal arrives during
3576 scm_internal_select, we won't any longer be forced do a context
3577 switch, but can remain in the same thread and deliver the signal
3580 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3581 scm_asyncs_pending and made it global.
3583 * iselect.c: Small fixes.
3585 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3586 coop_condition_variable_init, coop_condition_variable_wait,
3587 coop_condition_variable_signal): Changed return type from `void'
3588 to `int'. This is to adhere closer to the pthreads interface.
3589 This, in turn, is part of an attempt to provide C versions of the
3590 mutex and condition variable primitives which can be part of a
3591 frontend to COOP or pthreads.
3593 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3594 coop_condition_variable_destroy): New functions.
3596 * coop-threads.c (scm_wait_condition_variable): Use
3597 coop_condition_variable_wait_mutex.
3599 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3600 Definitions moved to coop-defs.h.
3602 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3603 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3604 scm_cond_destroy): New C interface to mutecis and cond vars.
3606 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3608 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3610 * iselect.c: Now several threads can wait on the same file
3611 descriptor. The behaviour is compatible with OS select: All
3612 threads waiting for the fd return with the same status.
3614 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3616 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3617 Can spawn a thread from application C code.
3619 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3621 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3622 gh_doubles2scm): New functions.
3624 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3626 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3627 commented-out version of gh_eval_str()
3629 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3631 * socket.c (scm_bind): free soka after use.
3633 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3635 * stime.c (tzvar): new variable.
3636 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3637 avoid memory leaks when allocating.
3639 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3641 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3644 * gc.c, tags.h: Doc fixes.
3646 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3648 * eval.c (macro-eval!): Removed. This function was a design bug.
3649 It allowed memoized code to leak out to the scheme level. Most
3650 things that you could do with `macro-eval!' can be done with
3653 1997-12-20 Tim Pierce <twp@skepsis.com>
3655 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3656 scm_fgets now depends on ftell(3) to know how many bytes were
3659 1997-12-15 Tim Pierce <twp@skepsis.com>
3661 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3662 dealing with strings.
3664 1997-12-13 Tim Pierce <twp@skepsis.com>
3666 Make %read-line more suitable for implementing read-line efficiently.
3667 * ioext.c (scm_read_line): Strip the terminating newline from a
3668 string, and return a cons of the string and its terminator.
3670 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3671 of the string that is read is stored in this memory location.
3672 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3673 * genio.c, genio.h (scm_do_read_line): Update caller.
3674 * ports.h (scm_ptobfuns): Update typedef.
3675 * fports.c (scm_fptob, scm_pipob): Update struct.
3677 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3679 * filesys.c (set_element): Return file descriptor.
3680 (fill_select_type): Return the highest file descriptor.
3681 (scm_select): Tell select about the highest file descriptor. On
3682 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3683 Therefore the extra overhead for calculating the maximum fd seems
3684 to be more than compensated. Is this correct? In any case,
3685 scm_internal_select will be much faster with this info.
3686 (scm_select, fill_select_type, set_element): Don't accept any kind
3687 of object in the file descriptor list or vector.
3689 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3691 * iselect.c (finalize_fd_sets): Bugfix.
3693 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3695 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3696 when using scm_internal_select (since we might switch to another
3699 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3701 * simpos.c (scm_system): always define: use sysmissing if not
3702 available. Check for HAVE_SYSTEM instead of _Windows (does
3703 Windows lack system or does it have an unusable one?).
3704 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3705 Let the argument be optional: if not supplied, call system(NULL).
3707 * ports.c (scm_close_port): relax the type check from OPPORTP to
3708 PORTP; closing a closed port is allowed.
3710 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3712 * fports.c (scm_fgets): Return if the last char in a chunk is
3713 newline. When fgets returns a string whose length is `size-1', it
3714 is ambiguous whether a whole line was retrieved, so we must check
3715 explicitly whether a line terminator is present.
3717 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3719 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3720 before taking the CDR. (Thanks to Harald Meland.)
3722 * filesys.c (scm_stat): Slightly optimized.
3724 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3726 * ports.c (scm_close_port): Make sure the port is open before
3729 * guile-snarf.in: Pass args through to gcc in a way that preserves
3730 whitespace boundaries. (Thanks to Greg Badros.)
3732 1997-12-02 Tim Pierce <twp@skepsis.com>
3734 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3735 statement. (Thanks to Doug Evans for pointing this out.)
3737 1997-12-01 Tim Pierce <twp@skepsis.com>
3739 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3741 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3743 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3744 errno macro expansion of this field name. (errno is a C
3745 preprocessor macro on some systems.)
3747 1997-11-29 Tim Pierce <twp@skepsis.com>
3749 * iselect.c: Doc fix.
3751 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3753 * init.c (scm_start_stack): Removed initialization of
3754 scm_the_last_stack_var.
3756 * backtrace.h: Declare scm_the_last_stack_var.
3758 * backtrace.c: Define scm_the_last_stack_var.
3760 * root.c (mark_root): Don't mark the_last_stack_var.
3762 * root.h (scm_root_state): Removed the_last_stack_var.
3764 * throw.c: Added #include "fluids.h"
3765 (ss_handler): `the-last-stack' is now a fluid.
3767 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3768 --> the_last_stack_fluid.
3770 * backtrace.c: Added #include "fluids.h"
3771 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3772 (scm_backtrace): `the-last-stack' is now a fluid.
3774 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3775 after scm_init_fluids.
3777 1997-11-28 Tim Pierce <twp@skepsis.com>
3779 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3781 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3782 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3784 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3786 * iselect.c (coop_next_runnable_thread,
3787 coop_wait_for_runnable_thread): Disable interrupts so that no
3788 async is executed before a potential error_revive.
3789 (scm_internal_select): Disable interrupts during the parts of the
3790 code which manipulate the sleep queue and the file descriptors.
3792 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3794 * Makefile.am: Added iselect.c and iselect.h.
3796 * coop.c (coop_qinit): Initialize fields used by
3797 scm_internal_select.
3798 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3799 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3800 replacement in iselect.c.
3801 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3802 coop_join): If GUILE_ISELECT enabled, use
3803 coop_wait_for_runnable_thread instead of
3804 coop_next_runnable_thread.
3805 (usleep, sleep): New replacements for system functions if
3806 GUILE_ISELECT is enabled.
3808 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3810 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3812 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3813 iselect.h. Implement Scheme level `select' using
3814 scm_internal_select. (See NEWS.)
3816 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3818 * init.c: Call scm_init_iselect.
3820 * iselect.h, iselect.c: New files. Implements
3821 scm_internal_select. (See NEWS.)
3823 1997-11-27 Tim Pierce <twp@skepsis.com>
3825 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3826 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3827 and scm_must_free, since ultimately the string returned will be copied
3828 by scm_makfrom0str anyway. Also, read any characters that may have
3829 been pushed onto the port with scm_ungetc.
3830 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3831 * ioext.c (scm_read_line): Free string after Guilifying it.
3832 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
3834 1997-11-26 Anthony Green <green@hoser.cygnus.com>
3836 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
3838 * gh.h: Safely wrap prototypes for c++ usage.
3840 1997-11-25 Mark Galassi <rosalia@cygnus.com>
3842 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3843 gh_repl (argc, argv).
3845 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3847 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3848 and to invoke scm_shell().
3849 (gh_launch_pad): took out the loading of boot-9.scm from here,
3850 since it is probably best to let the user control that. In fact,
3851 gh_repl() now invokes scm_shell() which does that.
3853 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3855 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3858 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
3860 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
3861 yesterday's underscore patch. (Thanks to Marius Vollmer for
3864 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
3866 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
3867 DLSYM_ADDS_USCORE is not defined.
3869 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
3871 * gh_data.c (gh_uniform_vector_length):
3872 (gh_uniform_vector_ref): started implementing the uniform types in
3875 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
3877 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3878 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3880 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3882 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
3883 configure.in was changed).
3885 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
3887 * Makefile.am (modinclude_HEADERS): Include readline.h here.
3888 * Makefile.in: Regenerated.
3890 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
3892 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
3893 OPORT is an `open' port, not an output port.
3895 * filesys.c (scm_close, set_element, get_element, scm_chown,
3896 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
3897 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
3898 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
3899 scm_close_port, scm_port_line, scm_set_port_line_x,
3900 scm_port_column, scm_set_port_column_x, scm_port_filename,
3901 scm_set_port_filename_x, scm_port_mode,
3902 scm_close_all_ports_except, scm_set_current_output_port,
3903 scm_set_current_error_port): Likewise
3904 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
3905 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
3907 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
3908 * backtrace.c (display_backtrace_body): Likewise
3909 * fports (scm_setvbuf): Likewise
3910 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
3911 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
3912 scm_getpeername, scm_send, scm_sendto): Likewise
3913 * unif.c (scm_uniform_array_write): Likewise
3915 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
3917 Minor problems with substring-related tag changes.
3918 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
3919 exactly what we want to leave in to detect substrings.
3920 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
3921 * tags.h: Fix diagrams and comments describing the S tag bit;
3922 remove vestigial remarks about the D tag bit.
3923 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
3924 * strings.c: Formatting tweaks.
3926 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
3927 variable first; then SCHEME_LOAD_PATH, with a warning message.
3928 (scm_parse_path): New function.
3929 * script.c: Doc fixes.
3931 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
3933 Readline support, from Daniel Risacher.
3934 * readline.c, readline.h: New files.

3937 * Makefile.am (libguile_la_SOURCES): Include readline.c.
3938 * Makefile.in: Regenerated.
3939 * scmconfig.h.in: Regenerated, after change to ../configure.
3941 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3943 * gh.h: gh_vector_set -> gh_vector_set_x
3945 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3947 * gh_data.c (gh_vector_set_x): changed name to make it consistent
3948 with the ! -> _x mapping when going from Scheme to C.
3950 1997-10-19 Mark Galassi <rosalia@cygnus.com>
3952 * gh.h (gh_reverse):
3960 (gh_assoc): added these gh_ functions implemented as macros.

3963 (gh_string_equal_p): added these two missing predicates.
3965 * gh_list.c (gh_append):
3970 (gh_set_cdr_x): added these routines as I go through and try to
3971 complete the picture R4RS functions that should be mirrored in the
3974 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3976 * tags.h (scm_tc7_substring): Changed the comment and code to
3977 conform with the changes below. Folks! We have suddenly two new
3978 free tc7 codes!!! Jummy, jummy!
3980 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
3982 * Makefile.in: Rebuilt.
3983 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
3985 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
3986 * unif.c (scm_vector_set_length_x): Don't handle multibyte

4000 * eq.c (scm_equal_p): Use SCM_TYP7S, not SCM_TYP7SD.
4001 * tags.h (SCM_TYP7SD): Removed.
4002 (SCM_TYP7D): Removed.
4003 (scm_tc7_mb_string): Removed.
4004 (scm_tc7_mb_substring): Removed.

4009 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
4011 Don't include "mbstrings.h".
4012 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
4013 (SCM_SYMBOL_SLOTS): Define as 4.
4014 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.

4035 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
4036 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
4038 1997-10-12 Mark Galassi <rosalia@cygnus.com>
4040 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
4042 * gh_test_c.c (c_vector_test): some improvements on the vector
4045 * gh.h (gh_vector): this used to exist but do the wrong thing.
4046 Now it (almost) does the right thing, though it takes a list
4047 instead of the individual arguments. I need to see how it could
4049 (gh_list_to_vector): added this function as a macro. Corresponds
4050 to Scheme's (list->vector ...).
4051 (gh_vector_to_list): added this function as a macro. Corresponds
4052 to Scheme's (vector->list ...).
4054 * gh_data.c (gh_vector_ref): renamed from gh_vref to
4055 gh_vector_ref, so that it resembles the Scheme routines more.
4056 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
4057 resembles the Scheme routines more.
4058 (gh_make_vector): this used to be (stupidly) called gh_vector().
4059 This is the right name, since it does the same thing as the Scheme
4060 (make-vector ...) procedure.
4062 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
4064 * ports.h: #include "libguile/print.h"
4066 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
4067 Some indentation fixes.
4069 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
4070 longer a user field; New field: class_flags.
4072 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
4074 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
4076 * gh_data.c (gh_bool2scm): new function which replaces
4077 gh_int2scmb(), which is now tagged as obsolete.
4079 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
4081 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
4082 macros should by convention not test for NIMPness.)
4083 (SCM_COERCE_OPORT): Adjust indentation.
4085 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
4086 SCM_NIMP test before SCM_PRINT_STATE_P.
4088 * struct.c, struct.h, gc.c: Renamed:
4089 scm_struct_i_layout --> scm_vtable_index_layout
4090 scm_struct_i_vcell --> scm_vtable_index_vcell
4091 scm_struct_i_vtable --> scm_vtable_index_vtable
4092 scm_struct_i_printer --> scm_vtable_index_printer
4093 scm_struct_i_vtable_offset --> scm_vtable_offset_user
4095 * struct.c (scm_print_struct): Use new printer slot; Default
4096 printing: Also output hex code of vtable so that type identity
4097 will be indicated as well.
4098 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
4099 Removed struct_printer_var; Removed struct-vtable-offset;
4100 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
4101 vtable-offset-user): New constants.
4103 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
4104 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
4105 If this slot contains a procedure, use that to print structures of
4106 the type represented by this vtable.
4108 * print.c (scm_iprin1): Don't print arguments of macro
4109 transformers. (They are always: exp env.); Bugfix: Unmemoize
4110 transformer source with correct environment.
4112 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
4114 Streamlining of call-with-dynamic-root:
4116 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
4117 there is now only one catch.
4118 (cwdr_outer_body): Removed.
4119 (cwdr_handler): New function.
4120 (scm_internal_cwdr): New function to perform the function of cwdr
4121 but take args that are more useful to C code. Also, the handler
4122 is now invoked *outside* of the new dynamic root, like the docs
4123 say. We no longer have to catch absolutely all errors, the caller
4124 is responsible for using a handler that does not throw, if he
4126 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4127 * root.h (scm_internal_cwdr): New prototype.
4129 Even more but risky streamlining:
4131 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4132 allocation of the jumpbuf of a root continuation. The changes
4133 below are controlled by it. They are now deactivated.
4134 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4135 the JMPBUF of the scm_rootcont to NULL before returning.
4137 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4138 when they are non-NULL.
4139 (scm_gc_mark): Likewise, mark only when non-NULL.
4141 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
4142 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
4144 * gc.c (scm_done_malloc): New function.
4145 gc.h (scm_done_malloc): New prototype.
4147 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
4148 (struct scm_print_state) [revealed]: New field.
4149 (scm_print_state_vtable): Make visible to the outside world for
4150 type checking purposes.
4151 (scm_valid_oport_value_p): New prototype.
4153 * print.c (scm_valid_oport_value_p): New function to check whether
4154 a certain value is acceptable as a port argument.
4155 (scm_print_state_vtable): New variable.
4156 (scm_free_print_state): Set `revealed' field to false.
4157 (scm_iprin1): Call user supplied closure printer with
4158 scm_printer_apply. Print in the traditional way when there isn't
4159 one or when it returns #f.
4160 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4161 Accept a port/print-state pair in addition to just a port.
4162 (scm_prin1): Don't return the print_state to the pool when it has
4164 (scm_printer_apply): Set `revealed' field of print_state to true.
4165 (scm_init_print): Set scm_print_state_vtable.
4166 (print_state_fluid, print_state_fluid_num): Removed.
4168 * throw.h (scm_handle_by_proc_catching_all): New prototype
4169 throw.c (scm_handle_by_proc_catching_all): New function
4171 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
4173 * Makefile.in: Regenerated with automake 1.2c.
4175 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
4177 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
4178 was looping endlessly.
4180 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
4182 * strports.c (scm_eval_string): Don't close the port.
4184 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
4185 former returns a nice normal integer. (Thanks to Daniel
4188 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
4190 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
4191 makefile variable as a build parameter called LIBS. The
4192 build-guile program will use this, for the time being.
4193 * Makefile.in: Regenerated.
4195 Thanks to Shiro Kawai:
4196 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
4197 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
4200 * Makefile.in: Regenerated with automake 1.2a.
4202 * script.c (scm_compile_shell_switches): If we hit the -c or --
4203 arguments, don't set the car of (command-line) to scm_usage_name,
4204 the prettified name of the guile executable; give it the full
4205 path, the way shells usually handle $0.
4207 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4209 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
4210 Scheme-level name `array-map' and renamed `serial-array-map' to
4211 `serial-array-map!'.
4213 * backtrace.c: Introduced exception handlers which now enclose
4214 `display-error' and `display-backtrace' so that error reporting
4215 won't get into infinite loops if an error occurs during displaying
4216 of the error. This can very easily happen with user supplied
4217 print call-back routines.
4219 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4221 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
4222 the names `serial-array-map' and `array-map' should be removed.)
4224 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
4226 * init.c (scm_boot_guile_1): Added scm_init_objects ().
4227 Added #include "objects.h"
4229 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
4230 Add #include "feature.h".
4232 * Makefile.am (libguile_la_SOURCES): Added objects.c.
4233 (modinclude_HEADERS): Added objects.h.
4235 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
4236 This test is needed at many places in the code and should be
4237 abstracted. (Motivated by the need of this test in libguiletk.)
4239 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
4240 (scm_eval_string), load.c (scm_primitive_load,
4241 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
4242 Use SCM_EOF_OBJECT_P.
4244 * eval.c (scm_init_eval): Add feature `delay'.
4246 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4248 * scmhob.h: Removed.
4250 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4252 * list.h (SCM_LISTn): New macros. Make list creation in C code
4253 prettier. The idea comes from STk.
4255 * sequences.h, sequences.c, append.h, append.c: Removed. These
4256 files implemented non-R4RS operations which would encourage
4257 non-portable programming style and less easy-to-read code.
4259 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
4262 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
4263 sequences.h, #include append.h.
4265 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
4268 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
4270 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
4272 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
4274 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4276 * eval.c: Added #include "objects.h"
4278 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
4281 * smob.c (scm_smob_prehistory): Create two objectsmobs with
4282 adjacent smob numbers.
4284 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4286 * procprop.h: Added declaration of scm_i_inner_name.
4288 * gsubr.c: New global symbol scm_i_inner_name.
4290 * debug.c (scm_procedure_name): Try procedure property
4291 `inner-name' if `name' fails.
4293 * print.c (scm_iprin1): Use scm_macro_name.
4295 * eval.c (scm_m_define): Give names to macros as well; Only the
4296 first top-level definition gives a procedure/macro a name.
4297 Otherwise confusing names can turn up in backtraces.
4298 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4299 `name'; Give names to macros as well.
4301 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4302 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4305 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4307 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4309 (prinmacro): Removed. The code has been moved/merged into print.c
4310 in order to decrease code redundancy. We want macros to print in
4311 a way equivalent to procedures, and it would be silly to duplicate
4312 the required code. (We don't want to maintain two places.)
4313 (macrosmob): Print field is now a NULL pointer.
4315 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4316 scm_macro_transformer): New prototypes.
4317 (scm_tc16_macro): Declared.
4319 * print.c (scm_iprin1): Added code for printing of macros. Macros
4320 are now printed in a way equivalent to procedures.
4322 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4324 * procs.h (scm_closure_p): Added declaration.
4326 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4328 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4329 Shouldn't pass "heap" as the subr name.
4331 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4333 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4334 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4335 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4336 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4337 SCM_BOOL_T. Any non-false value is true.
4339 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4341 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4342 scm_gensym): Added prototypes.
4344 * symbols.c (scm_gensym): New function. This will speed up
4345 certain types of applications (such as macro systems) which
4346 generate lots of symbols.
4348 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4350 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4352 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4354 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4355 specifier, since (2) or (2 . 3) would cause SEGV.
4356 (scm_transpose_array): more argument checking fixes.
4358 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4360 * Makefile.in: Regenerated.
4362 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4364 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4366 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4368 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4370 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4372 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4373 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4376 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4377 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4378 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
4379 scm_array_p, scm_array_rank, scm_array_dimensions,
4380 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
4381 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
4382 scm_array_prototype): Added case scm_tc7_wvect.
4384 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
4386 * errno.h: prototype for scm_strerror.
4387 * error.c (scm_strerror): new procedure.
4389 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4391 * list.c (scm_list_append_x): Allow non-pair as last argument.
4392 This is consistent with the R4RS append and is probably the
4393 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4395 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4397 * stime.h: prototype for scm_times.
4398 * stime.c (scm_times): new procedure.
4399 * ioext.c (scm_fseek): if the first argument is a file descriptor
4401 (scm_ftell): if the first argument is a file descriptor call lseek
4403 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
4404 * filesys.c (scm_chmod): if the first argument is a file descriptor,
4406 (scm_chown): if the first argument is a port or file descriptor,
4408 (scm_truncate_file): new procedure.
4409 Add DEFER/ALLOW INTS to a few other procedures.
4410 (scm_fsync): new procedure.
4411 (scm_open_fdes): new procedure.
4412 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
4414 (scm_fcntl): the first argument can now be a file descriptor. The
4415 third argument is now optional.
4417 * posix.c (scm_execl, scm_execlp): make the filename argument
4418 compulsory, since omitting it causes SEGV.
4419 (scm_sync): return unspecified instead of #f.
4420 (scm_execle): new procedure.
4421 (environ_list_to_c): new procedure.
4422 (scm_environ): use environ_list_to_c. disable interrupts.
4423 (scm_convert_exec_args): take pos and subr arguments and
4424 improve error checking.
4426 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4428 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4429 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4430 argument to SCM_ASSERT. Furthermore, the name of the function
4431 should be passed as first argument when signalling
4432 SCM_WNA. (Thanks to Thomas Morgan)
4434 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4435 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4436 dispatches on the number of actual args has a default case
4437 reporting an internal error. This is a vestige from a version
4438 that mallocated a SCM vector to hold the arguments. In the
4439 current version this check is too late: if it ever happens we will
4440 have already overstepped the bounds of the array.
4442 Also, the patch [...] adds a check for too many actual arguments."
4444 mdj: Removed check for "internal programming error".
4446 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4448 * gh_io.c (gh_write): New function.
4450 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
4451 throw.c (scm_internal_stack_catch): New sibling to the other catch
4452 functions. Code moved from gh_eval.c.
4453 throw.h: Added header.
4454 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
4455 scm_internal_stack_catch.
4457 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4459 * ioext.h: fix up prototypes.
4460 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
4461 Scheme name is now dup->fdes.
4462 (scm_dup_to_fdes): make the second argument optional and
4463 fold in the functionality of scm_primitive_dup.
4464 (scm_primitive_dup): deleted.
4466 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
4468 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
4469 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
4470 ultrix are defined. Use setvbuf instead of setbuf.
4471 (scm_setvbuf): new procedure.
4472 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
4473 (scm_setfileno): moved from ioext.c.
4474 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
4475 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
4477 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4479 * fluids.c (scm_fluid_p): New function.
4480 * fluids.h (scm_fluid_p): New prototype.
4482 Sat Jul 26 21:33:37 1997 Marius Vollmer <mvo@zagadka.ping.de>
4484 * print.c (scm_iprin1): Enter printed structures into the print
4485 state as nested data while they are printed.
4486 (print_state_fluid, print_state_fluid_num): New variables.
4487 (scm_init_print): Initialize them.
4488 (scm_iprin): If print_state_fluid carries a print_state, use that
4489 instead of creating a new one.
4490 (scm_printer_apply, apply_stub, struct apply_data): New
4491 definitions to help with calling printer functions written in
4493 * print.h (scm_printer_apply): New prototype.
4495 * struct.c (scm_print_struct): Use scm_printer_apply to call the
4496 user defined struct printer.
4498 * dynwind.c (scm_dowinds): Handle fluids on the wind list.
4499 * fluids.h (scm_internal_with_fluids, scm_with_fluids,
4500 scm_swap_fluids, scm_swap_fluids_reverse): New prototypes.
4501 * fluids.c (scm_internal_with_fluids, scm_with_fluids,

4504 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
4506 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
4507 SCM_ASSERT: arg comes before pos.
4509 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4511 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
4512 to a list of length zero correctly.

4528 Mon Jul 21 04:03:42 1997 Gary Houston <ghouston@actrix.gen.nz>
4530 * ioext.h: removed scm_duplicate_port prototype.
4532 * ioext.c (scm_primitive_dup2): return the new file descriptor
4533 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
4535 (scm_fdopen): bug fix: don't try to make port unbuffered until its
4536 stream has been set.
4537 (scm_duplicate_port): deleted, there's now an implementation in
4539 (scm_primitive_dup2): do nothing if newfd == oldfd.
4541 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
4543 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

4550 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
4552 * ports.h: prototypes too.
4553 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
4555 * fports.h: prototype too.
4556 * fports.c (scm_evict_ports): moved from ioext.c.
4558 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
4560 * ports.c (scm_close_port): return a boolean instead of unspecified.
4561 throw an error if an error other than EBADF occurs.
4563 * filesys.h: scm_close prototype.
4564 * filesys.c (scm_close): new procedure, can close file descriptors
4565 and ports (scsh compatible).
4567 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
4570 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
4572 * fluids.c, fluid.h: New files.
4573 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
4574 (modinclude_HEADERS): Added "fluids.h"

4583 (scm_make_root): Call scm_copy_fluids to make fluid bindings
4584 unique for the new root when it has a parent.
4586 * smob.h: Include "libguile/print.h" to make scm_print_state
4589 * dynl.c (free_dynl_obj): New function to free the dynamic object
4590 data. (dynl_smob): Use it.
4591 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4592 the dynamic object data below the linking of the object to avoid
4593 memory leak when the linking code throws an error. Now the code
4594 leaks a whole dynamically linked library when must_malloc throws,
4595 but that should be much less likely.
4597 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4599 Changes to compile under gnu-win32, from Marcus Daniels:
4600 * stime.c (tzset): If tzset isn't provided, make it a NOP.
4601 (scm_localtime): Change SCM_EOF to SCM_EOL.
4602 (scm_mktime): Likewise.
4603 * socket.c: Don't include sys/un.h unless autoconf tells
4604 us Unix domain sockets are available.
4605 (scm_fill_sockaddr): Ignore Unix domain code.
4606 (scm_addr_vector): Likewise.
4607 (scm_init_addr_buffer): Likewise.

4609 found during autoconf.
4610 * simpos.c (SYSTNAME): Treat cygwin like Unix.
4611 * scmsigs.c (scm_pause): Don't include unless pause was found
4613 * posix.c (scm_getgroups): Don't include unless support function
4614 was found during autoconf (in this case, getgroups).
4615 (scm_setpwent): For setpwent.
4616 (scm_setegid): For setegid.
4617 * net_db.c (scm_inet_netof): Don't include unless support
4618 function was found during autoconf (in this case, inet_netof).
4619 (scm_lnaof): For inet_lnaof.
4620 (scm_inet_makeaddr): For inet_makeaddr.

4632 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
4633 scm_misc_error, not SCM_EOF.
4635 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
4636 arguments for formatting the error message, not SCM_BOOL_F. I
4637 think this is left over from the (eq? '() #f) days.
4639 * read.c (recsexpr): Give this a dummy definition if
4640 DEBUG_EXTENSIONS isn't #defined.
4642 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
4644 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

4654 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
4655 alloca.lo will be included in @LIBLOBJS@. Something better than
4656 this should be possible.
4657 * Makefile.in: Regenerated.
4659 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4661 * simpos.h: prototype for scm_primitive_exit.
4662 * simpos.c (scm_primitive_exit): new procedure, terminates the
4663 process without unwinding the stack.
4665 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
4667 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
4668 argument and logior its components together, so the user doesn't
4669 have to do this explicitly. Also, if regexp/basic is supplied, then
4670 turn off REG_EXTENDED.
4671 (scm_init_regex_posix): New regexp/basic symbol.
4672 (REG_BASIC): #define this if it is not already present.
4674 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4676 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.

4678 (CLEANFILES): New target, clean versiondat.h, libpath.h.
4679 (DISTCLEANFILES): New target, clean *.x.

4688 * Makefile.in: Regenerated.
4690 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
4691 flag; I don't think we support it.
4692 (scm_make_regexp): Make sure the user doesn't pass the
4695 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
4697 (scm_init_regex_posix): Define constants for the REG_mumble flags;
4698 name them according to the SCSH convention: regexp/mumble.
4700 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
4702 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
4704 * Makefile.am (libpath.h): Include the values of all the standard
4705 Makefile directory variables. Print a message, but don't print
4707 (versiondat.h): Print a message, but don't print all the commands.
4708 * load.c: #include "alist.h".
4709 (init_build_info): New function.
4710 (scm_init_load): Call it.
4711 * Makefile.in: Regenerated.
4713 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
4715 * root.c: Establish a reliable catch-all handler for the new root.
4716 After all the Scheme handler function might signal an error too,
4717 and we don't want to lose that.
4718 (cwdr_inner_body): Renamed from cwdr_body.
4719 (cwdr_outer_body): New function, to establish the user's handler,
4720 and pass control to cwdr_inner_body.
4721 (cwdr): Establish the reliable catch-all handler here, and pass
4722 control to cwdr_outer_body.
4723 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
4724 the user's handler through to cwdr_outer_body.
4725 * throw.c (scm_handle_by_message): Move guts into....
4726 (handler_message): New static function.
4727 (scm_handle_by_message_noexit): New function.
4728 * throw.h (scm_handle_by_message_noexit): New prototype.
4730 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
4731 across this. Only works on GCC. Otherwise, we hope for the best.
4732 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4733 the feeling that real thread systems will not need this...
4735 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4737 Try to detect when people are using one version of libguile and a
4738 different version of ice-9. People have been skewing things and
4739 sending in bug reports.
4740 * Makefile.am (versiondat.h): New file to generate.
4741 * version.c: #include "versiondat.h", to get version info.
4742 (scm_libguile_config_stamp): New function.

4745 * scmconfig.h.in, Makefile.in: Regenerated.
4746 * Makefile.in: Regenerated.
4748 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
4749 primitive definitions under their Scheme names.
4751 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4752 1:2. Helps avoid confusion between installed and uninstalled libs.
4754 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
4757 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
4758 backslash from definition; this should be used like: GDB_INTERFACE;
4760 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4762 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
4763 new port unbuffered until its stream has been set.
4765 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
4767 * ports.h: new prototype.
4768 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
4770 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
4772 Make things compile neatly under Sun's C compiler.
4773 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
4774 * extchrs.c (xmbtowc): Make the second arg a normal char, not
4775 unsigned, because that's what the ANSI function takes.
4776 * extchrs.h (xmbtowc): Corresponding change to prototype.
4777 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4779 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
4780 argument plain char *.
4781 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
4783 * tag.c (scm_tag): Remove unreachable statement.
4784 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4785 top of the word, it should be unsigned.
4787 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4788 is defined, to avoid warnings; it's only used in the
4789 conflict-checking code. Which might go away anyway.
4790 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4791 conditionals; put the label definition in an #if too, to stifle
4794 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4795 ChangeLog-threads in the distribution.
4796 * Makefile.in: Regenerated.
4798 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4800 * guile-snarf.in: Changed regexp to support CPPs that insert
4801 whitespace between lexical tokens (which munges the `%%%' snarf
4804 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4806 * load.c (scm_init_load_path): Append $(datadir)/guile to
4807 %load-path, so modules do not have to be installed in Guile's
4808 current version directory.
4810 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
4812 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
4813 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
4814 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
4815 call the sysdep functions with deferred ints.
4816 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
4817 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
4818 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
4821 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
4824 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
4826 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
4828 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
4830 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
4833 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
4835 * eval.c (scm_lookupcar1): New procedure to cope with a race
4836 condition during lookup (when using threads).
4837 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4838 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4841 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4843 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4844 supplied. (Change from Tim Pierce.)
4846 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4848 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4849 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4850 default and not `()'. `#f' is the canonical non-value in Scheme,
4853 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4855 * struct.c (struct_printer): New variable that holds a handle on
4856 the Scheme variable *struct-printer*. This variable can be set by
4857 Scheme code to override the printing of structures.
4858 (scm_print_struct): If struct_printer is set, call it. If it is
4859 not set, or returns #f, print the structure in the old fashion.
4860 Include "eval.h" for scm_apply.
4862 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4864 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4865 scm_struct_i_n_words to get the number of fields, not
4866 -scm_struct_n_extra_words.
4868 On the route to fancier struct printing:
4869 * struct.c (scm_print_struct): New function to print a structure.
4870 Include "genio.h" to support it. This function doesn't do
4871 anything interesting right now, but I think it should be here
4873 * struct.h: Include "print.h" and add prototype for
4875 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4876 print structures ourself.
4878 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4880 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
4881 before applying the handler in case it doesn't return.
4883 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
4885 * scmsigs.h, async.h: updated.
4887 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
4890 * posix.c (scm_uname): interpret only negative values as an error.
4891 Solaris normally returns a positive value.
4893 * script.c (scm_compile_shell_switches): if we are not going into
4894 an interactive repl, set scm_mask_ints to zero so that asyncs can
4897 * simpos.c (scm_system): don't ignore/unignore signals around
4900 * posix.c (scm_open_pipe): don't ignore/unignore signals around
4903 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
4904 done in boot-9.scm instead.
4906 * scmsigs.c, async.c: Major rewriting of signal handling code.
4907 (scm_sigaction): new procedure.
4908 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
4910 (scm_raise): return unspecified, throw error on failure.
4912 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4914 * regex-posix.c (scm_init_regex_posix): Register the "regex"
4915 feature, to help boot-9.scm decide whether to import the regex
4918 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
4920 * eval.c: Include scmconfig.h at the beginning of the file so that
4921 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
4924 * regex-posix.c: #include "_scm.h" before conditionally #including
4925 <regex.h>; the former defines HAVE_REGCOMP.
4927 * regex-posix.c: #include <regex.h> conditionally, so the file is
4928 CPP'able (for dependency scanning) even on systems that don't have
4931 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4933 Add new R4RS-compliant syntax for keywords.
4934 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
4935 regardless of the setting of the `keywords' read option.
4936 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
4937 can be re-read no matter what the setting of the `keywords' read
4940 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
4942 Add support for POSIX regular expressions.
4944 * regex-posix.c, regex-posix.h: New files. (Some code
4945 is taken liberally from rx/rgx.c in the old Guile dist.)
4947 * init.c: Include regex-posix.h.
4948 (scm_boot_guile_1): Call scm_init_regex_posix.
4950 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
4951 Add regex-posix.[ch] sources.
4952 * Makefile.in: Regenerated.
4954 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
4955 to do this automatically? It didn't for me, bleh.)
4957 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
4959 * fports.c (print_pipe_port): New function.
4960 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
4961 latter doesn't even take the right arguments.
4963 * Makefile.am: Increment shared lib revision number. I think
4964 sometimes the uninstalled Guile finds the installed shared lib;
4965 Gord says doing this might help. As things turned out, I can't
4966 say whether it does.
4967 * Makefile.in: Regenerated.
4969 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
4970 passing it as the closure argument to scm_boot_guile. (Bill
4973 * ports.c (print_void_port, putc_void_port, puts_void_port,
4974 write_void_port, flush_void_port, getc_void_port, close_void_port,
4975 noop0): Use ANSI prototypes instead of K&R declarations, so the
4976 initialization of void_port_ptob gets aggressively type-checked.
4977 Fix arguments of print_void_port and write_void_port. (Bill
4980 * COPYING, __scm.h, _scm.h, alist.c, alist.h, append.c, append.h,
4981 appinit.c, arbiters.c, arbiters.h, async.c, async.h, backtrace.c,

5011 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
5013 * script.c (scm_find_executable): Use prototype-style definition
5014 here; apparently it's not quite right to have const in a prototype
5015 and then use a K&R declaration. I wonder if stuff like this will
5016 go away if we compile with -Wrequire-prototypes, or whatever that
5017 is... (Bernard URBAN)
5019 * scmhob.h: New text from Bernard URBAN.
5021 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5023 * script.c: Don't #define const on hpux. Configure takes care of
5024 this. (Thanks to Larry Schwimmer.)
5026 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5027 decide whether to #include <unistd.h>, instead of listing a bunch
5028 of systems. Don't #include stdio twice. Removed dyked-out
5029 definition of scm_find_impl_file.
5031 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5033 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5034 library version info to 1:0.
5035 * Makefile.in: Regenerated.
5037 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,
5038 gdb_interface.h, gdbint.c, gdbint.h, gh_data.c, gh_init.c,
5039 gh_io.c, gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c,

5041 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5042 throw.c: Update copyright years; these files have been worked on
5043 significantly in 1997, but only had copyright years for 1996.
5044 Also, change name of copyright holder on some from Mikael
5045 Djurfeldt to Free Software Foundation; he has signed papers
5046 assigning the changes to the FSF.
5048 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5049 reason not to give the user the option.
5051 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5052 Return #f on end-of-file when scanning table (i.e. when called
5053 with no arguments). Try to catch errors, when we can.
5054 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5056 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5057 external declarations. These are useful.
5059 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5061 * posix.c: don't include <sys/select.h> or define macros for
5062 select, since they were not used in this file.
5064 * filesys.c (scm_select): make the fifth parameter microseconds,
5065 not milliseconds. let the fourth parameter be either a real value
5066 or an integer or #f. The first, second and third arguments can
5067 now be vectors: the type of the corresponding return set will be
5069 (set_element, get_element): new static procedures.
5071 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5073 * strports.c (scm_eval_string): New function.
5074 (scm_eval_0str): Trivially re-implemented in terms of
5076 * strports.h (scm_eval_string): New extern decl.
5078 * net_db.c (h_errno): Add extern decl for this.
5080 * fports.c (local_pclose): New function.
5081 (scm_pipob): Use it in the initializer here.
5084 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5085 Use a meaningful error message when signalling an error. For
5086 this, scm_gethost must check h_errno rather than errno.
5088 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5090 * Makefile.in: Regenerated, using automake-1.1p.
5092 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5094 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5095 not SCM_UNSPECIFIED.
5097 * script.c (scm_compile_shell_switches): don't append (quit) if
5099 (scm_shell): call scm_exit_status and exit on the result of the
5102 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5104 Ensure that shared substrings are handled properly when passed to
5105 a system call or other foreign function. Many thanks to Tim
5107 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5108 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5109 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5110 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,
5111 scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone,
5112 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
5113 (scm_display_error_message): use RO macros when strings may be RO.
5114 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
5115 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
5116 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
5117 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
5118 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
5119 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
5120 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
5121 scm_strftime), vports.c (scm_make_soft_port): use
5122 SCM_COERCE_SUBSTR to make sure shared substrings are
5125 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5127 * error.c (scm_error): Add newline to error message.
5129 * init.c (scm_init_standard_ports): Doc fix.
5131 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5133 * dynl-shl.c: Completely replaced with new code from Bernard
5136 * script.c (scm_ice_9_already_loaded): New variable.
5137 (scm_compile_shell_switches): Use it.
5139 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5141 * filesys.c (scm_input_waiting_p): add missing third argument to
5144 * stime.c (scm_localtime): copy the result of localtime before
5145 calling gmtime in case they share a buffer.
5146 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5149 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5151 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5153 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5155 * Makefile.am (check-local): New target, which causes 'make check'
5156 to run gh_test_c and gh_test_repl, with some trivial input.
5157 * Makefile.in: Rgnrtd.
5159 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5161 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5164 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
5166 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
5167 sure how this was supposed to work.
5168 (scm_async_click): don't send SCM_TICK_SIGNAL.
5169 (scm_init_async): don't initialize %tick-thunk.
5171 * the following change doesn't affect the Scheme interface:
5172 gc-thunk is called at the end of garbage collection. however it's
5173 no longer implemented by pretending it's a signal.
5175 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
5176 system async corresponding to scm_gc_thunk.
5177 * async.h: declare scm_gc_async.
5178 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
5179 gc-thunk directly, instead of going through a signal handler.
5180 (scm_gc_async): new variable, points to the GC system-async.
5181 (scm_init_async): save the GC async as scm_gc_async instead
5182 of using system_signal_asyncs.
5183 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
5185 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
5187 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
5188 Don't screw up if we're interrupted.
5189 * Makefile.in: Regeneradet.
5191 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
5193 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
5195 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
5196 we're not using AM_INIT_GUILE_MODULE any more.
5197 * Makefile.in: Reneregated.
5199 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5201 Functions for finding variable bindings, grace à Tim Pierce.
5202 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
5203 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
5205 Get 'make dist' to work again.
5206 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
5207 * Makefile.in: Regenerated, like a surry without a fringe on top.
5209 Changes for reduced Guile distribution: one configure script,
5211 * configure.in, configure: Removed.
5212 * acconfig.h, acinclude.m4: Moved to parent directory, where the
5213 real configure script lives.
5214 * Makefile.in, scmconfig.h.in: Regenerated.
5216 * init.c: #include "script.h", to get prototype for script.c's
5219 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
5221 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
5222 scm_must_malloc, not raw malloc.
5224 * script.c (scm_compile_shell_switches): Dyke out debugging output
5227 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5229 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
5231 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
5232 system has them. Hope this is safe. Previously
5233 sys/timeb.h was included if HAVE_FTIME was defined or if
5234 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
5235 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
5237 * ioext.c (scm_setfileno): add missing third argument to
5238 scm_misc_error call.
5240 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
5242 * eq.c (scm_equal_p): Correctly compare strings of different
5243 varieties. (Thanks to Tim Pierce.)
5245 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
5247 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
5248 #! block comment must occur on a line all by itself.
5250 Move most of the guts of shell command processing into libguile,
5251 so guile.c can be very small (and eventuallly auto-generated. (I
5252 mean, generated mechanically, not self-generated. Hmm.))
5253 * guile.c, script.c, script.h: New source files.
5254 * init.c (scm_boot_guile_1): Call scm_init_script.
5255 * libguile.h: #include "script.h".
5256 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
5257 targets, for new executable.
5258 (libguile_la_SOURCES): Mention script.c.
5259 (modinclude_HEADERS): Add script.h.
5260 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
5261 not dynamic linking is enabled. This is because we're generating
5262 executables now. Move CY_AC_WITH_THREADS call after those, so the
5263 values of cy_cv_threads_libs captures the libs chosen above.
5264 * Makefile.in, configure, aclocal.m4: Regenerated.
5266 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
5267 We don't maintain this interface any more, and it just confuses
5270 * alloca.c: #include <scmconfig.h>, not <config.h>.
5271 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
5272 it'll get included in disties.
5274 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5276 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
5277 be distributed, because they confuse people.
5278 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
5280 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
5282 * configure.in: check for presence of gethostent (not present on
5283 OpenBSD by default).
5284 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
5285 * configure, scmconfig.h.in: Regenerated.
5287 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5289 * backtrace.c (scm_backtrace): Split message string across
5290 newlines properly. GCC is more tolerant of this than other
5293 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
5295 Merge threads directory into libguile.
5296 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5297 threads.h: New source files.
5298 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
5299 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
5301 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5302 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5303 coop-threads.c.cygnus, coop-threads.h.cygnus.
5304 * configure.in: If we're using threads, include threads.o in
5306 * _scm.h, libguile.h: threads.h lives in this directory now.
5307 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5308 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5309 currently used, but brought along for information's sake.
5310 * ChangeLog-threads: log from old 'threads' directory.
5311 * Makefile.in, configure: Rebuilt.
5313 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5315 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5318 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5320 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5322 Merge GH interface library into libguile.
5323 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
5324 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5325 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5326 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5328 (EXTRA_libguile_la_SOURCES): ... here.
5329 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5330 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5331 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5332 New variables, describing how to build the gh test programs.
5333 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5334 build the test programs, and we probably should have been linking
5335 libguile.la against them all along, to support AIX shared libs.
5336 Add cflags for threads to CFLAGS; add libs for threads to new
5337 variable THREAD_LIBS, used in Makefile.am.
5338 * ChangeLog-gh: log from old `gh' subdirectory.
5339 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5341 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5343 * acconfig.h: Undo change of Apr 9; including the definition of
5344 PACKAGE in the guile headers conflicts with applications' own
5346 * scmconfig.h.in: Regenerated.
5348 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
5350 * filesys.c (scm_fcntl): New function from Roland McGrath.
5351 (scm_init_filesys): New symbols for use with fcntl.
5352 * filesys.h: Added prototype.
5354 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
5355 when PROC is receiving no arguments.
5357 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5359 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5360 have S_IFSOCK. This is the case under Ultrix.
5362 * posix.c (scm_status_exit_val, scm_status_exit_val,
5363 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5364 Ultrix versions of WIFSTOPPED, etc., which assume that their
5365 arguments are lvalues (hmm).
5367 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5369 * eval.c: Doc fixes.
5371 * throw.c: Doc fixes; rearranged.
5373 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
5375 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
5377 * acconfig.h: Added entry for PACKAGE.
5378 * scmconfig.h.in: Regenerated.
5380 Changes to work with automake-1.1n, which has better libtool support.
5381 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5382 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5384 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5386 * Makefile.in: Rebuild.
5388 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5390 * stime.c (scm_mktime): take an optional zone argument.
5391 (scm_localtime): check putenv return value.
5392 (scm_strftime, scm_strptime): moved from posix.c. move #include
5394 stime.h, posix.h: update prototypes.
5395 (bdtime2c, setzone, restorezone): new static procedures.
5396 (scm_mktime, scm_strftime): use them.
5397 (scm_strftime): don't call mktime before strftime. Use
5398 filltime for return value.
5399 (filltime): convert NULL zname to #f.
5400 (scm_strptime): return a count of characters consumed, not
5401 the remaining string.
5403 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5405 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
5406 (scm_mktime): likewise.
5408 Uncomment localtime and mktime.
5410 * configure.in: add AC_STRUCT_TIMEZONE.
5412 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5414 * stime.c (scm_init_stime): don't define ticks/sec.
5415 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5416 return value problem and is still portable.)
5418 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5420 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5421 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5422 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5423 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5424 cpp_err_symbols.c): Corresponding changes.
5425 * Makefile.in: Regenerated.
5427 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5429 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5430 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5431 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5432 * putenv.c: new file, from sh-utils 1.12.
5434 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5435 since allocation isn't for Scheme objects.
5436 (scm_putenv): copy strings before placing in the environment.
5438 * stime.c (scm_current_time): throw an error if time returns -1,
5439 instead of returning #f.
5440 (scm_get_internal_real_time, scm_get_internal_real_time): use
5441 scm_long2num for return value instead of SCM_MAKINUM.
5443 * stime.h: prototypes updated.
5445 * stime.c (scm_time_in_msec): apparently unused, deleted.
5447 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5449 * configure.in: check for gettimeofday.
5451 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5452 which may be more usefully portable than a gettimeofday interface.
5454 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5456 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5458 * Makefile.in: Regenerated.
5460 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5462 * stime.c (filltime): recovered static procedure.
5463 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5466 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5467 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5469 * posix.c (scm_mknod): split the mode argument into type and perms
5470 arguments, like the extra fields returned by stat.
5472 * fports.c (scm_pipob): set the close, free and print procedures.
5473 (scm_close_pipe): new procedure.
5475 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5476 define them in boot-9.scm
5478 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5480 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5481 wan't defined. Don't include fd.h.
5483 * Previously fd.h was regenerated whenever configure was run,
5484 forcing a couple of files to be recompiled.
5486 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5487 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5488 Check for _fileno as well as _file.
5490 * ioext.c: don't fd.h.
5491 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5494 * Change the stratigy for getting information about errno
5495 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5496 generating lists of symbols during the build process, which will
5497 not always work, include comprehensive lists in the distribution.
5498 To help keep the lists up to date, the "check_signals" and
5499 "check_errnos" make targets can be used.
5501 * configure.in: don't check for a command to extract errno codes.
5502 * Makefile.am: update file lists, remove errnos.list and errnos.c
5503 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5504 check_errnos targets.
5505 (CLEANFILES): remove errnos.c and errnos.list, add
5506 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5507 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5508 * errnos.default: deleted.
5509 * cpp_signal.c: new file.

5511 * cpp_err_symbols, cpp_sig_symbols: new files.
5512 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5513 * error.c (scm_init_error): #include cpp_err_symbols instead of
5515 * posix.c (scm_init_posix): don't intern signal symbols. #include
5518 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5520 * strop.c (scm_i_index): allow the lower bound to be equal to the
5521 length of the string, so a null string doesn't always give an error.
5523 * posix.h: new prototypes.
5524 * posix.c (scm_status_exit_val, scm_status_term_sig,
5525 scm_status_stop_sig): new functions, as in scsh. They break down
5526 process status values as returned by waitpid.
5528 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5530 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5531 configure doesn't know about it.
5533 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5535 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5537 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5538 which defines C variables with global linkage.
5540 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5542 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5545 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5547 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5548 has time to check why this doesn't work well with continuations.
5550 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5552 * Fix shell syntax error; some shells won't tolerate
5553 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5555 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5557 * posix.c (scm_uname): throw an error if uname fails instead
5560 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5562 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
5565 * async.c (scm_ints_disabled): definition moved from error.c.
5567 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5569 * acconfig.h: Removed PACKAGE.
5571 * scmconfig.h.in: Regenerated.
5573 * snarf.h: g++ says it's non-portable not to specify the first
5574 argument in a varargs declaration. I introduced the first
5575 argument by using preprocessor conditionals.
5577 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5579 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5580 (scm_freopen): use RO string macros for filename and modes.
5581 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
5583 * posix.c (scm_getgrgid): simplify conversion of name to C string.
5584 (scm_mknod): use RO string macros for path.
5586 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
5587 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5589 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5590 use SCM_ROSTRINGP and SCM_ROCHARS.
5592 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5594 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5597 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5598 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5599 support for byte vectors.
5601 * print.c (scm_iprin1): Limit number of vector elements printed
5602 according to pstate->length.
5604 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5606 * backtrace.c (scm_display_error_message): don't segv if message
5609 * error.h: prototype for scm_error_scm.
5611 * error.c (scm_error_scm): new procedure, reimplements scm-error
5612 in C and uses scm_error.
5614 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5616 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5617 pointer to the Scheme variable read-hash-procedures and intern it
5618 in scm_init_read. Modify scm_read_hash_extend and
5619 scm_get_hash_procedure to use the pointer.
5621 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5623 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5624 (SCM_KEYWORD_STYLE): defined.
5626 * read.c (scm_read_opts): add a keywords option. This isn't a
5627 boolean option, in case someone wants to add support for DSSSL
5629 Setup scm_keyword_prefix symbol.
5630 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5632 I've left keyword support disabled by default, since it doesn't
5633 seem to break the module system and it gives R4RS standard behaviour.
5634 It can be reactivated with (read-set! keywords 'prefix).
5636 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5638 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5639 before constructing arbiter.
5641 * eval.c (scm_m_define): Bugfix: Check that the object is a
5642 closure before setting the procedure property!
5644 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5646 * ports.c: Removed `ungetc-char-ready?'.
5648 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5650 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5651 (idea from Mikael: make it a pair so scm_permanent object only
5653 (scm_read_hash_extend): don't call scm_permanent_object.
5654 (ideas from Mikael): if chr is already in the list, replace its
5655 procedure instead of appending it again. If proc is #f, remove
5657 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5659 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5661 * gdbint.c (gdb_read): update scm_lreadr usage.
5663 * load.h: update prototypes.
5665 * load.c (scm_primitive_load, scm_read_and_eval_x,
5666 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
5668 * read.h: add prototype for scm_read_hash_extend. Change args for
5671 * read.c (scm_read_hash_procedures): new variable.
5672 (scm_read_hash_extend): new procedure.
5673 (scm_get_hash_procedure): new procedure.
5674 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5675 for extended # processing.
5676 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5677 scm_read_token): remove case_i, sharp arguments. Change callers.
5679 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5681 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5682 (SCM_CASE_INSENSITIVE_P): define.
5684 * read.c: add case-insensitive option to scm_read_opts.
5685 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5686 to determine whether to convert symbol case.
5687 (default_case_i): definition removed.
5688 * read.c (scm_read_token): if case_i, downcase ic before doing
5691 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5693 * configure.in: Added configuration option `guile-debug'.
5694 Configure with --enable-guile-debug if you want a bunch of extra
5695 functions used for debugging when developing Guile.
5697 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5699 * procs.c (make-cclo): New undocumented debugging procedure: Make
5700 compiled closure with internal procedure PROC and length LENGTH.
5701 Only compiled if GUILE_DEBUG is defined.
5703 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5705 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5707 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5709 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5710 with 3 or more args internally to the evaluator.
5712 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5714 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5715 with 3 or more args internally to the evaluator. This is mainly
5716 because we don't want to pass entry and exit points of the
5717 debug support twice, but it also seems to increase the speed of
5718 the evaluator for such calls (e. g. (+ 1 2 3)).
5720 * backtrace.c (scm_display_application): New procedure:
5721 display-application; Set fancy printing parameters individually
5722 for different types of display (backtrace, error, application).
5723 (These should of course be customizable!)
5725 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5726 clear the CHECK-flags.
5728 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5730 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5732 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5734 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5735 from pairs with a GLOC in the car.
5737 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5738 otherwise `symbol-hash' will behave badly.
5739 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5740 we get segmentation fault!
5742 * symbols.c: Added #include "weaks.h". New functions:
5743 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5744 moved to an extraneous library when we split libguile.)
5746 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5748 * filesys.c (scm_stat): stat now takes fport arguments too as
5749 documented in the manual.
5751 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5753 * debug.c (scm_single_step): Bugfix: Call continuation with
5754 scm_call_continuation instead of throwing to it.
5756 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5758 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5759 argument wasn't declared to be optional.
5761 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5763 * stime.c (scm_init_stime): Add feature "current-time".
5765 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5767 * throw.h: prototype for scm_exit_status.
5768 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5769 args to derive an exit status. Allows (quit) to work from a
5771 (scm_exit_status): new function.
5774 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5776 * eval.c (scm_deval): Removed some old code.
5777 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5779 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5782 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5785 * procs.c: Introduce the existent C function scm_thunk_p at the
5786 Scheme level as well.
5788 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5790 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5791 used from C to easily lookup the value of a symbol in the current
5794 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5796 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5797 scm_init_unif in this file. This will also fix a previous problem
5800 * configure.in: Added AM_MAINTAINER_MODE
5802 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5804 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5807 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5809 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5810 source files that are not always included in libguile but should
5811 have their dependencies calculated by automake. This variable is
5812 recognized by automake, no further magic is needed.
5813 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5814 to deal exclusively with *.lo files, as it seems. The *.o files
5815 are built automatically when the corresponding *.lo file gets
5818 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5820 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5823 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5825 * unif.c (scm_array_set_x): minor change to argument error checking.
5827 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5829 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5830 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5831 They should only be included in the library at configure.in's
5833 (libguile_la_LDADD): Include the appropriate .lo files here.
5834 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5835 so we know when to build them (and their .lo bretheren).
5836 * configure.in (LIBLOBJS): New substituted variable. We let
5837 configure decide which .o files to include in LIBOBJS, and then
5838 put the corresponding list of .lo files in LIBLOBJS. The latter
5839 is what we pass to libtool.
5840 * Makefile.in, configure: regenerated.
5842 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5844 * symbols.c (scm_sysintern0): New function. Contains the core of
5845 old scm_sysintern but doesn't take a second value argument.
5846 (scm_sysintern): Now uses scm_sysintern0.
5847 (scm_sysintern_no_module_lookup): Renamed to
5848 scm_sysintern0_no_module_lookup and doesn't take a second value
5849 argument any longer.
5851 * symbols.h (scm_sysintern0: Added declaration.
5853 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5854 scm_sysintern when interning option keys. Otherwise we risk
5855 destroying the values of already interned variables.
5857 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5858 scheme-level boolean (use SCM_NFALSEP).
5860 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5862 (scm_backtrace): New function. (C version of old function from
5863 boot-9.scm) Motivation: Make it possible to display backtraces
5864 without depending on boot-9.scm. (I'm uncertain if this
5865 motivation is good enough...)
5867 * root.h (scm_root_state): Add member the_last_stack_var.
5868 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5870 * root.c (mark_root): Mark scm_the_last_stack_var.
5872 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5875 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5877 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5878 1. mark_lazy_catch didn't mark the smob.
5879 2. Both functions above have standard variants:
5880 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5881 free_lazy_catch --> scm_free0.
5883 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5885 * throw.c (scm_internal_lazy_catch): New function.
5886 (scm_lazy_catch): Rewritten to use it.
5887 (scm_ithrow): Handle the new lazy catch representation.
5888 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
5889 that doesn't have a jmpbuf is a lazy catch clause.
5890 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
5891 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
5892 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
5894 (scm_init_throw): Register the new lazy-catch smob type.
5895 * throw.h (scm_internal_lazy_catch): decl for new function.
5897 * throw.c (scm_internal_catch): Doc fixes.
5899 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
5900 configure.in. Including this might cause problems if applications
5901 that link against libguile include their own copies of alloca, but
5902 if they're using autoconf, they should be adding libguile to LIBS
5903 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
5904 the copy in libguile, and things will be okay. (I think.)
5906 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5908 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
5910 strop.h: move prototypes too.
5912 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5914 * posix.c (scm_init_posix): don't intern EINTR since it's now done
5917 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
5918 etc. I deleted them from filesys.c long ago, but didn't
5919 notice they were here too (although ineffective since
5920 sys/stat.h wasn't included).
5922 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
5924 * eval.c: Don't define alloca in GCC case. gcc will automatically
5925 use __builtin_alloca if appropriate.
5927 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5929 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
5930 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
5931 that values of automatic variables are preserved. See comments
5932 for safe_setjmp for details.
5934 Change from Thomas Morgan:
5935 * variable.c: Include eq.h.
5936 (var_equal): New function.
5937 (variable_smob): Use var_equal as the discriminator for variables.
5939 * throw.c (s_throw): Remove extraneous declaration.
5941 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
5942 * eval.c: Add necessary CPP cruft to support that.
5943 * configure, Makefile.in, scmconfig.h.in: regenerated.
5945 Change from Thomas Morgan:
5946 * procprop.c (scm_procedure_properties): Convert the Scheme
5947 boolean returned by scm_procedure_p into a C boolean before using
5948 it as a condition for SCM_ASSERT.
5949 (scm_procedure_property): Likewise.
5951 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
5952 indications of Unixness.
5955 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5957 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
5959 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5961 * read.c (scm_lreadr): use scm_misc_error to improve one of the
5962 "unknown # object" error messages.
5964 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
5965 (scm_i_index) and declare it static. Add a 'direction' argument
5966 to indicate what way the search should go.
5967 (scm_i_index): throw out-of-range error instead of wrong-type-arg
5969 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
5970 strop.h: remove scm_i_index, scm_i_rindex prototypes.
5972 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5974 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
5976 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
5977 to avoid clash with various scsh forks.
5979 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
5981 The following two changes (ramap.c, throw.c) are motivated by the
5982 apparent unportability of forward declarations of static arrays of
5983 the form `static foo bar[];'.
5985 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
5986 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
5988 * throw.c (scm_throw): Moved above scm_ithrow.
5990 * options.h: Removed the extern declarations of scm_yes_sym and
5991 scm_no_sym since these are static.
5993 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5995 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
5997 * Makefile.am: remove AWK=@AWK@.
5998 Add a rule for generating errnos.list.
5999 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6001 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6002 don't extract errnos, just set a variable (avoids the
6003 need to recompile error.c just because configure is run.)
6005 * unif.h: update prototypes.
6006 * unif.c (scm_uniform_array_read,write): change the offset and
6007 length arguments to start and end, for consistency.
6009 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6011 * ioext.h: update prototypes.
6012 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6013 scm_read_line_x, it's a more general procedure using an
6014 interface from scsh. read-line and read-line! are now defined
6016 Note that the new read-line trims the terminator
6017 by default, previously it was appended to the returned string. An
6018 optional argument specifies how to process the terminator (scsh
6019 compatible). For the old behaviour: (read-line port 'concat).
6020 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6021 returns a pair, but is converted to multiple values if the scsh
6024 socket.h: update prototypes.
6025 * socket.c (scm_recvfrom): for consistency with other procedures,
6026 take start and end as separate optional arguments.
6027 (scm_recv, scm_recvfrom): don't allow the second argument
6028 to be a size, only a buffer. Change the scheme names to
6029 recv! and recvfrom!. Don't return the buffer.
6031 * ioext.h, posix.h: move prototypes too.
6032 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6033 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6034 "read.h" and "unif.h".
6035 * ioext.c: include "chars.h"
6037 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6039 * dynl.c: The dynamic linking and module registration functions
6040 are now defined even when dynamic linking is not available for the
6041 host system. Some of their functionality can be done without
6042 dynamic linking; when it's really needed, they throw errors.
6044 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6046 * configure.in: Only define DYNAMIC_LINKING when one of the system
6047 dependent functions is detected.
6048 * dynl.c (scm_dynamic_func): New function to get the address of a
6049 function in a dynamic object.
6050 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6051 produced by scm_dynamic_func as the thing to call.
6053 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6055 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6056 (scm_register_module_xxx, scm_registered_modules,
6057 scm_clear_registered_modules): New functions.
6059 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6061 * symbols.c (scm_sysintern): Renamed to
6062 scm_sysintern_no_module_lookup.
6063 (scm_sysintern): New function to take the place of the old
6064 scm_sysintern. It uses the current toplevel lookup closure to give
6065 the symbol its value. This is a temporary hack to put packages
6066 like gtcltk into their own module.
6067 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6068 us whether `scm_top_level_lookup_closure_var' has been initialized
6070 * eval.c (scm_init_eval): Set it.
6072 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6074 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6075 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6077 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6079 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6080 scm_sys_dup): deleted: FD capability will be added to other
6082 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6083 scm_fd_free, fd_smob, scm_intern_fd.
6084 (scm_open): renamed from scm_sys_open. Return a port instead of
6085 an FD object. Make the mode argument optional.
6086 (scm_sys_create): deleted, it's just a special case of open.
6087 (scm_init_filesys): move interning of constants O_CREAT etc.,
6088 here (were previously using SCM_CONST_LONG macro).
6089 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6091 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6092 include "fports.h" and <stdio.h>
6093 (scm_stat, scm_select): don't support FD objects.
6095 * error.h: adjust scm_syserror_msg prototype.
6096 * error.c (scm_syserror_msg): take an extra argument for errno.
6097 Using the global value didn't always work, since it could be
6098 reset by procedure calls in the message or args arguments.
6100 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6101 I don't understand why the check was there (and what about the
6104 * strop.c (scm_string_copy): allow shared substrings to be copied.
6106 * unif.h: corresponding change to prototypes.
6107 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6108 recognize two new optional arguments: offset and length. Allow
6109 the port argument to be an integer (file descriptor, for scsh).
6110 Include <unistd.h> for "read" prototype.
6112 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6114 * socket.c: don't include filesys.h.
6116 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6118 * Makefile.am: add AWK=@AWK@ (?)
6120 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6122 Add a rule to generate errnos.c from errnos.
6123 * error.c (scm_init_error): include errnos.c.
6124 * errnos_cnvt.awk: new file, converts the list of errno codes to
6126 * errnos_get.c: new file.
6127 * errnos.default: new file, contains errnos to try if they can't
6128 be extracted from errno.h.
6129 * configure.in: if using GCC, try and extract errno codes from
6133 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6135 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6136 * Makefile.am: Made libguile into a libtool library.
6137 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6138 Set libtool_libs to indicate that libguile is a libtool library.
6139 See guile/ChangeLog for details.
6140 * .cvsignore: ignore "*.lo", the libtool library objects.
6142 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6144 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6145 use htons in getservbyport argument.
6147 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6149 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6150 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6153 * objprop.c (scm_object_property): No need to take the CDR of the
6154 value returned by scm_object_properties, since Aug 20 change.
6156 * configure.in: When checking for struct linger, #include
6157 <sys/types.h> as well as <sys/socket.h>. I've never known
6158 <sys/types.h> to cause any portability problems, and Solaris's
6159 <sys/socket.h> needs it.
6160 * configure: Rebuilt.
6162 I think the Sun compiler has chosen a perverse way to interpret
6163 ANSI declarations combined with K&R definitions. We'll
6164 appease it a little bit. But when it invades France, we fight.
6165 * print.c (scm_iprlist): Change 'tlr' argument to an int.
6166 * print.h (scm_iprlist): Here too.
6167 * numbers.c (scm_divbigdig): Change definition to match
6168 declaration in numbers.h.
6169 * unif.c (scm_makflo): Change definition to match declaration in
6172 * init.c (scm_boot_guile): Don't return the value of
6173 scm_boot_guile_1. This function doesn't return a value;
6174 scm_boot_guile_1 doesn't return a value (or return at all).
6176 * eval.c (unmemocopy): Add a semicolon to appease the Sun
6179 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
6180 compile. I have a feeling this function is a bad idea anyway ---
6181 one should always test for features, not systems.
6183 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
6184 semicolons. Only pure luck kept this from being noticed earlier.
6186 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
6188 * socket.c (scm_recvfrom): Added missing semicolon.
6190 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6192 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
6193 the buffer and start and end positions for scsh networking
6196 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
6198 * configure.in: Revert previous change to this file; the problem
6199 is due to transient automake weirdness.
6200 * configure: Rebuilt.
6202 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
6203 PLUGIN/guile.libs. configure generates the latter from the former.
6204 * Makefile.in: Rebuilt.
6206 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
6207 need this if we install scripts, like guile-snarf.
6208 * configure: Rebuilt.
6210 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6212 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
6214 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
6216 * socket.c (scm_addr_vector): fix faulty scm_listify.
6218 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
6220 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
6221 style block comment is no longer considered an error.
6223 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
6225 * PLUGIN/guile.libs.in: New file.
6226 * PLUGIN/guile.libs: Removed from repository.
6227 * configure.in: Create PLUGIN/guile.libs from
6228 PLUGIN/guile.libs.in. This is for including additonal libraries
6229 needed for dynamic linking.
6230 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
6231 instead of PLUGIN/guile.libs.
6233 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
6235 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
6237 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
6238 occurrences of the given element from the list, not just the
6239 first. This is how the Emacs Lisp functions behave, how the
6240 analogous Common Lisp functions behave, and (I believe) how the
6241 older Maclisp functions worked. I realize that this change may
6242 break code, but it seemed better to break it before the Guile
6245 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
6246 Their prototypes were already present in gc.h, but they weren't
6248 (scm_init_storage): Initialize scm_protects.
6249 * root.c (scm_protects): New element of scm_sys_protects.
6251 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
6253 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6255 * libguile.h: Added #include "libguile/net_db.h".
6257 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
6258 30 change. That file is only meant for communication between the
6259 configuration process and load.c. If code linked against libguile
6260 wants to get at the paths mentioned in libpath.h, it can call
6261 functions declared in load.h.
6263 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6265 * libguile.h: Removed #include "libguile/fdsocket.h"
6267 * net_db.c: Added #include <sys/socket.h>.
6269 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
6271 * filesys.c (scm_input_waiting_p): use select in preference to
6272 FIONREAD, since the latter doesn't detect EOF.
6273 Throw error if neither select nor FIONREAD available.
6275 * socket.c (scm_connect): take a port, not a fd object.
6276 (scm_fill_sockaddr): throw an error if fam is not recognised.
6277 (scm_bind): use scm_fill_sockaddr.
6278 (scm_listen): take a port, not a fd object.
6279 (scm_accept): take and return a port. return #f in the car if
6280 address can't be got
6281 (scm_sock_fd_to_port): new procedure.
6282 (scm_socket): use scm_sock_fd_to_port.
6283 (scm_addr_vector): throw error if unrecognised address type.
6284 take an extra argument with the calling procedure name.
6285 (scm_getsockname): take a port. return #f if address can't be got.
6286 (scm_getpeername): take a port. return #f if address can't be got.
6287 (scm_recvfrom): take a port. return #f for address component if can't
6289 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6290 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6292 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6294 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6295 use separate data pointers, to allow them to be designed
6296 independently and reused.
6297 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6298 Renamed from catch_body, catch_handler, and uncaught_throw; made
6300 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6302 (scm_catch): Use the above.
6303 (scm_throw): Don't bother printing a message for an uncaught
6304 throw; we establish a default handler in init.
6305 * throw.h (scm_internal_catch): Prototype updated.
6306 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6308 (struct scm_body_thunk_data): New structure, used as data
6309 argument to scm_body_thunk.
6310 * init.c (struct main_func_closure): New structure, packaging up
6311 the data to pass to the user's main function.
6312 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6313 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6314 scm_internal_catch to establish a catch-all handler, using
6315 scm_handle_by_message. This replaces the special-case code in
6317 (invoke_main_func): Body function for scm_internal_catch; invoke
6318 the user's main function, using the main_func_closure pointer to
6319 decide what to pass it.
6320 * root.c (struct cwdr_body_data): Remove handler_proc member.
6321 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6322 (cwdr_handler): Removed.
6324 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6326 * socket.h (SCM_P): update bind prototype.
6327 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6328 include "feature.h".
6329 (scm_socket): return a port, not a file descriptor object.
6330 include "fports.h" and <unistd.h>
6331 (scm_bind): take a port, not a file descriptor object.
6332 take an extra argument for address args.
6334 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6335 INADDR_NONE, INADDR_LOOPBACK.
6337 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6339 * init.c: include net_db.h and not fdsocket.h.
6340 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6342 * Makefile.am: corresponding changes.
6343 * socket.h: renamed from fdsocket.h, fix names.
6344 * net_db.h: renamed from socket.h, fix names.
6345 * socket.c: renamed from fdsocket.c.
6346 remove _sys from procedure names.
6347 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6348 add "socket" to features list.
6349 * net_db.c: renamed from socket.c.
6350 remove _sys from procedure names.
6351 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6352 add "net-db" to features list.
6353 include "net_db.h". don't include <sys/socket.h> or
6356 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6358 * tags.h (scm_tags): Removed comma at end of last enumerator.
6360 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6362 Don't use GCC extensions to allocate space for debugging frames.
6363 (Here he goes again! Why do we put up with this?!)
6364 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6365 an scm_debug_info structure, not an in-line array of them. Add
6366 'info' member, to say how many vect elements we've used, for eval
6368 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6369 a new variable debug_info_end to mark the end of vect, instead of
6370 the address of the 'info' pointer itself.
6371 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6372 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6373 (SCM_APPLY): Explicitly allocate space for debug.vect.
6374 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6375 * stacks.c: Adjusted for new debug frame structure.
6376 (RELOC_INFO, RELOC_FRAME): New macros.
6377 (stack_depth, read_frames): Use them, and new scm_debug_frame
6378 element 'info', instead of magically knowing that eval frames have
6379 an info pointer sitting after vect.
6380 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6382 (scm_init_stacks): Formatting tweaks.
6384 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6386 Give GCC more control flow information, so it can be sure that
6387 variables aren't used uninitialized.
6388 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6389 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6390 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6391 scm_misc_error): Tell GCC that these functions never return.
6392 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6393 out the field type, call abort if SCM_ASSERT returns, to placate
6395 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6396 scm_wta ever returns. We can't handle this case anyway, and this
6397 gives the optimizer more information.
6398 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6399 scm_wta ever returns.
6401 In some cases, the code is fine, but GCC isn't smart enough to
6402 figure that out; this usually happens when one variable is only
6403 initialized and used when a particular condition holds true, and
6404 we know that condition will never change within a given invocation
6405 of the function. In this case, we simply initialize the variables
6406 to placate the compiler, hopefully to a value which will cause a
6407 crash if it is ever actually used.
6408 * print.c (scm_iprin1): Initialize mw_pos.
6409 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6410 * throw.c (scm_ithrow): Initialize dynpair.
6411 * unif.c (scm_uniform_vector_ref): Initialize cra.
6412 * struct.c (init_struct): Initialize prot.
6413 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6415 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6416 if EXPR contains no expressions.
6418 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6420 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6421 cause an infinite loop (???). So much for the algebraic
6422 equivalency of variable-sized arrays and alloca...
6424 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6426 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6427 a SCM boolean, not a C boolean.
6429 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6431 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6432 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6433 rules for raising scm_mtrigger. Previously, unfortunate but not
6434 unlikely circumstances could result in almost constant invokation
6435 of the gc. Now, this situations should be less likely, but they
6436 are not prevented completely.
6438 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6440 * numbers.c (scm_fuck): Procedure removed; looks like old test
6442 * numbers.h: Prototype removed.
6444 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6446 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6447 array to a pointer, to match my Nov 21 change in eval.c.
6449 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6451 * libguile.h: Added #include "libguile/backtrace.h", #include
6452 "libguile/stacks.h".
6454 * strings.c (scm_string scm_make_string scm_string_ref
6455 scm_string_set_x scm_string_equal_p scm_string_append):
6456 Bugfix according to scm patch from Aubrey Jaffer:
6457 Corrected long-standing
6458 (not (eqv? (integer->char 128)
6459 (string-ref (make-string 1 (integer->char 128)) 0)))
6460 bug found by John Kozak <jk@noontide.demon.co.uk>.
6462 * strports.c, strports.h: Make scm_eval_0str return the value of
6463 the last expression evaluated (previously, it returned void).
6465 * strports.c, strports.h: New function: scm_read_0str. Does what
6468 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6470 * simpos.c (scm_getenv): return #f if string can't be found in the
6471 environment instead of throwing an exception, for compatibility
6472 with numerous other systems.
6474 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6476 * Makefile.am (.c.x): Use guile-snarf.
6477 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6479 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6481 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6483 * backtrace.c (scm_display_error_message): Made non-static, and
6484 renamed from display_error_message.
6485 * backtrace.h (scm_display_error_message): Added extern decl.
6486 * throw.c (uncaught_throw): Use it to display the error message.
6488 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6490 * inet_aton.c: Use #if 0, not #ifdef 0.
6492 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6494 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6495 to convert the returned value.
6496 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6497 the offset argument.
6499 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6501 Add new interface to catch/throw, usable from C as well as
6503 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6504 (scm_internal_catch): New function, replaces...
6505 (scm_catch_apply): Deleted.
6506 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6507 mechanism which is a bit more code, but can be used nicely from C
6508 and implement the Scheme semantics as well.
6509 (scm_internal_catch): This is the replacement; it's named after
6510 the analogous function in Emacs.
6511 (scm_catch): Reimplemented in terms of the above.
6512 (struct catch_body_data, catch_body, catch_handler): New
6513 functions, used by scm_catch.
6514 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6515 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6516 support for new cwdr.
6518 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6521 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6523 * acconfig.h: Added DYNAMIC_LINKING symbol.
6524 * configure.in: Add option and checks for dynamic linking.
6525 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6526 dynl.h: New files for dynamic linking support.
6527 * Makefile.am (libguile_a_SOURCES):
6529 (modinclude_HEADERS): Added "dynl.h".
6530 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6532 * init.c (scm_boot_guile_1): Call
6533 scm_init_dynamic_linking to initialize dynamic linking support.
6535 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6537 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6538 (as we Schemers say). It needs to be global, so that I can tweak
6539 it for the proper operation of unexec.
6540 (scm_boot_guile_1_live): New variable, see above.
6542 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6544 * guile-snarf.sh: Removed.
6545 * PLUGIN/guile.libs: Added dependency for -lm.
6546 * acinclude.m4: Renamed from aclocal.m4.
6547 * PLUGIN/greet: Removed.
6548 * Makefile.am, aclocal.m4: New files.
6549 * configure.in: Updated for Automake.
6551 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6553 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6554 and not top_level_lookup_thunk_var.
6556 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6558 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6560 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6562 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6563 Scheme function, instead of syntax. Single argument is now a
6566 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6568 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6569 scm_ra_divide): Properly terminate statements passed as arguments
6570 to IVDEP macros. (Thanks to Bernard Urban.)
6572 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6573 with non-constant sizes. (Thanks to Bernard Urban.)
6575 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6577 It's an "eval closure", not an "eval thunk." A thunk is a
6578 function of no arguments.
6579 * root.h (struct scm_root_state): Renamed
6580 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6581 (scm_top_level_lookup_closure_var): Renamed from
6582 scm_top_level_lookup_thunk_var.
6583 * root.c (mark_root): Uses changed.
6584 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6585 * init.c (scm_start_stack): Uses changed.
6586 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6587 Change scheme-visible name to *top-level-lookup-closure* from
6588 *top-level-lookup-thunk*.
6590 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6592 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6593 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6595 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6597 * gc.c (struct scm_heap_seg_data): Doc fixes.
6599 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6600 sweeping. Then, prepend each segment's free cells to its
6601 freelist, rather than wiping out the old value. (Thanks to Marius
6604 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6605 scm_check_freelist, scm_debug_newcell): New functions and
6606 variables, for debugging freelist problems.
6607 * pairs.h (SCM_NEWCELL): New debugging version added.
6608 * gc.h (scm_debug_newcell): Added extern declaration, used by
6609 debugging version of SCM_NEWCELL.
6611 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6613 On some systems <libc.h> conflicts with <unistd.h>, and should not
6614 be #included at all.
6615 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6616 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6617 * configure.in: Call it.
6618 * posix.c, filesys.c: Use its results to decide whether or not to
6620 * configure, scmconfig.h.in: Rebuilt with autoconf and
6623 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6625 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6626 pointer to the stdio stream before calling scm_setbuf0, so the
6627 latter will be able to retrieve it. I'm surprised this didn't
6628 segfault earlier. (Thanks to Christopher Lee.)
6630 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6632 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6635 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6637 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6638 number of stack narrowing specifier pairs. The first specifier in
6639 a pair controls inner border, the second the outer border. A
6640 number means cut that number of frames, a procedure object means
6641 cut until that object is found in operator position in a frame.
6643 * root.c (cwdr): Bugfix.
6645 * read.c: Recording of positions disabled by default.
6647 * procs.c (scm_closure_p): New function.
6649 * posix.c (scm_tmpnam): New function.
6651 * load.c: Added #include "throw.h".
6652 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6655 * load.c, load.h (scm_read_and_eval_x): New function.
6657 * eval.c: Renamed debug option "deval" to "debug".
6659 (scm_eval_x): `eval!' is no longer accessible from the scheme
6660 level. Motivation: We can't allow operations which introduce
6661 glocs into the scheme level. Guile's type system can't handle
6662 these as data. Use `eval' or `read-and-eval!' as replacement.
6664 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6665 SCM_CONSP since this is a macro!; Set vframe.prev to
6666 scm_last_debug_frame instead of 0. In this way we can look
6667 "above" the virtual start stack frame if we wish.
6668 (scm_debug_hang): New function: Useful for debugging Guile in
6669 certain tricky situations. Will probably be removed later...
6671 * debug.h: Changed semantics of debug option "backtrace". This
6672 option now only indicates whether we want automatic backtrace at
6675 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6677 * ports.c: #include "filesys.h"
6678 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6680 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6681 Motivation: This is system specific code which is related to file
6682 I/O. It also may use select. Added code by Gary Houston to
6683 detect presence of character in stdio buffers.
6685 * libguile.h: #include "libguile/libpath.h"
6687 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6688 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6689 SCM_SITE_DIR; Install libpath.h among the other include files.
6691 * load.c, load.h (scm_sys_package_data_dir): New function.
6693 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6695 * stacks.h: Bugfix: Don't use tail-array length field as stack
6696 length field! This screwed GC.
6698 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6700 * _scm.h: Added #ifndef around definition of macros min and max.
6702 * __scm.h: Added hooks for threads to plugin to in ints protection
6703 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6704 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6705 the main code in these macros duplicated and spread over multiple
6706 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6707 SCM_THREAD_SWITCHING_CODE.
6709 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6711 * snarf.h: New file.
6712 * guile-snarf.sh: New file.
6713 * Makefile.in (inner_h_files): Added snarf.h
6714 (ancillary, install, uninstall, distclean): Added actions for
6716 (.c.x): Use guile-snarf.
6717 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6718 (gen_c_files): Note that these depend on guile-snarf.
6719 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6720 now in "snarf.h". Added #include "snarf.h" to get them.
6721 * libguile.h: Added #include "snarf.h".
6722 (Patches applied and tweaked by Jim Blandy.)
6724 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6726 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6727 standards suggest against providing prototypes for system
6728 functions. Thanks to Greg Troxel.
6730 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6732 * strports.c (scm_eval_0str): New function.
6733 #include "read.h", to get prototype for scm_read.
6734 * Makefile.in (strports.o): Update dependencies.
6735 * strports.h: New prototype.
6737 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6738 scheme name from "int?" to "integer?". It seems to do the job.
6739 * numbers.h: Rename prototype too.
6740 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6743 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6744 scm_num_eq_p): Rename these according to R4RS conventions: call
6745 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6746 to making libguile R4RS compliant without ice-9...
6748 * load.c (scm_sys_search_load_path): Search for files under all
6749 extensions listed in the %load-extensions variable. If FILENAME
6750 is absolute, return it unchanged, without searching the load path.
6751 (scm_loc_load_extensions): New variable, pointing to
6752 %load-extensions' value cell.
6753 (scm_init_load): Initialize it, and the value it points to.
6754 (scm_primitive_load_path): Improve error reporting.
6756 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6757 of new Scheme variable %load-hook.
6758 (scm_primitive_load): Apply %load-hook to filename.
6760 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6762 * configure.in: add tests for figuring out whether buffered data
6763 is available in a FILE structure, which is needed by char-ready.
6765 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6768 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6769 exceptions using misc_error instead of syserror. It seems a bit
6770 odd to throw an exception if a string can't be found in the
6771 environment, but it's consistent with open-file, stat etc.
6772 (simpos.h): remove sys_ from getenv.
6774 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6775 occurs, throw an error instead of returning errno. Return value
6777 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6779 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6781 * filesys.c (scm_stat2scm): derive file type and permissions from
6782 the stat mode and append them to the returned vector.
6783 There isn't much overhead in doing this and it avoids the need to
6784 work with S_IRUSR et al. in Scheme.
6785 Define symbols scm_sym_regular etc.
6786 (scm_init_filesys): don't intern S_IRUSR etc.
6788 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6789 and s_primitive_load_path.
6791 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6793 * error.h: don't declare error symbols. prototype for scm_misc_error.
6795 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6798 * error.c: use SCM_SYMBOL to set up error keys.
6799 scm_misc_error: new procedure.
6801 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6803 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6804 between `#!' and `!#' is ignored.
6805 (skip_scsh_block_comment): New function.
6807 * feature.c (scm_set_program_arguments): New argument, FIRST.
6808 * feature.h: Update prototype.
6809 * init.c (scm_boot_guile_1): Pass new argument to
6810 scm_set_program_arguments.
6812 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6814 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6815 (scm_boot_guile): Call scm_set_program_arguments here, later than
6816 the old initialization.
6818 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6819 initialization procedure.
6820 - Delete in, out, err arguments; there are other perfectly good
6821 ways to override these when desired.
6822 - Delete result argument; this function shouldn't ever return.
6823 - Rename init_func argument to main_func, for less confusion.
6824 - Delete boot_cmd argument; main_func is more general.
6825 -Add 'closure' argument, to help people pass data to main_func
6826 without resorting to global variables.
6827 - Abort if reentered; don't bother returning an error code.
6828 - Call scm_init_standard_ports to set up the default/current
6829 standard ports; no need to pass them to scm_start_stack.
6830 - Remove code to evaluate the boot_cmd, and start the repl; let
6831 the user do something like that in main_func if they want.
6832 - Remove code to package up a return value; main_func can do any
6834 - Call exit (0), instead of returning.
6835 (scm_start_stack): Don't initialize the I/O ports here; that's
6836 weird. Delete in, out, err arguments. Move guts to
6837 scm_init_standard_ports, scm_stdio_to_port.
6838 (scm_init_standard_ports): New function, to set up current and
6839 default standard ports.
6840 (scm_start_stack, scm_restart_stack): Make these static.
6841 * init.h (scm_boot_guile): Adjust declaration.
6842 (scm_start_stack, scm_restart_stack): Remove externally
6843 visible declarations for these.
6844 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6846 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6847 written out several times in scm_start_stack.
6848 * fports.h: New declaration for the above.
6850 * feature.c (scm_set_program_arguments): New function.
6851 * feature.h: New declaration for the above.
6853 * ports.c: Formatting tweak.
6855 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6857 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6858 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6859 for obtaining the address of a car or cdr field. Motivation:
6860 &SCM_CXR make assumptions about the internal structure of the
6863 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6864 Motivation: see SCM_CXRLOC.
6866 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6867 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6868 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6869 Motivation: Safer use. Some other macros are defined in terms of
6870 these operations. If these are defined using the SCM_SETCXR
6871 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6872 to inefficiency and an <e1> with side-effects could potentially
6873 break. Also, these particular operations are heavily utilized in
6874 the garbage collector. In unoptimized code there will be a
6877 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6878 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6879 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
6880 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
6881 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
6882 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6883 vports.c: Cleaned up use of pairs: Don't make any special
6884 assumptions about the internal structure of selectors and
6885 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6886 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
6887 (Among other things, this change makes it easier to build Guile
6888 with certain compilers which have problems with casted lvalues.)
6890 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6892 * stacks.c: Improve selection of relevant stack frames when making
6893 a stack object. Introduce one level of indirection in the stack
6894 object to make it possible to "narrow" to a certain region of the
6895 stack. This facilitates making use of more clever algorithms (not
6896 implemented) for selecting relevant frames and gives a cleaner
6897 design since selection of frames can be done independently of
6898 extraction of frames from the real stack.
6899 (scm_stack_id): Also take #t as argument which means look at
6902 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
6903 Turn n_tail into an integer directly representing current number
6904 of frames in stack. Add field tail.
6906 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
6908 * debug.c (scm_make_memoized): Made it available at scheme level.
6909 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
6910 SCM_NIMP before applying heavier predicates in argument checking.
6911 (scm_local_eval): Also take memoized object as argument.
6913 * backtrace.c (scm_display_error): Just a safety measure: Stacks
6914 aren't created with zero length, but should such a strange
6915 creature suddenly turn up...
6917 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
6919 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
6920 `del', for the sake of C++ compilers. (Patch applied by JimB.)
6922 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
6924 * variable.c (scm_make_variable): Make the name hint optional, as
6926 (anonymous_variable_sym): Renamed from variable_sym. All uses
6929 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
6930 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
6931 of scm_primitive_load_path was also changed to
6932 "primitive-load-path", from "%try-load-path". Callers changed.
6933 We'd like to respect the convention that a function named
6934 "try-mumble" should behave just like the function called "mumble",
6935 but return #f instead of signalling some error.
6936 * load.h: Rename prototypes.
6938 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6940 * print.c (make_print_state, grow_print_state), print.h: Modified
6941 the print state representation: Don't use a tail array for
6942 recording of circular references. Resizing of the print state
6943 structure invalidates the print state pointer. To avoid passing
6944 around an indirect print state reference to all printing
6945 functions, we instead let the print state reference a resizable
6948 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
6950 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
6951 Don't crash when passed an improper list terminated by a
6952 non-immediate value.
6954 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
6956 Allocate data for structures on an eight-byte boundary, as
6957 required by the tagging system.
6958 * struct.c (alloc_struct): New function.
6959 (scm_make_struct, scm_make_vtable_vtable): Call it.
6960 * struct.h (scm_struct_n_extra_words): Bump to 3.
6961 (scm_struct_i_ptr): New "field".
6962 * gc.c (scm_gc_sweep): When we need to free the data, use the
6963 information stored by alloc_struct to find the beginning of the
6964 block allocated to the structure, so we can free it.
6966 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6968 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
6971 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
6972 (scm_debug_info): New member: id.
6974 * stacks.c: Stacks are now represented as structs; Stacks have an
6975 id given to them by `start-stack'.
6976 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
6978 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
6979 Changed stack representation.
6981 * debug.c (scm_procedure_name): Try procedure property `name' for
6982 compiled closures aswell.
6984 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
6986 * eval.c: scm_i_name moved to gsubr.c
6987 (scm_m_define): Record names of all kinds of procedure
6988 objects. (Earlier, only closures were recorded.)
6990 * procprop.h: Added declaration of scm_i_name.
6992 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
6993 (scm_make_gsubr): Record names of compiled closures.
6995 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6997 * debug.c, debug.h: Removed obsolete code.
6999 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7000 stacks.c: Renamed regs --> scm_contregs.
7002 * print.c (scm_free_print_state): Cleanup print state before
7003 returning it to pool. It is better to do it here than in
7004 scm_prin1 since scm_prin1 is called often.
7006 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7007 s_set_source_property_x): Check that first argument is a pair or a
7010 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7011 scm_i_line, scm_i_column and scm_i_breakpoint global.
7013 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7014 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7017 * debug.h: Added debug object smob declaration and macro
7020 * configure.in: Build with backtrace.o and stacks.o if debug
7023 * Makefile.in: Added entries for new files: backtrace.c,
7024 backtrace.h, stacks.c and stacks.h.
7026 * symbols.c (scm_sym2ovcell): Fixed documentation.
7028 * _scm.h (min, max): Added.
7030 * async.c: Moved `min' macro to _scm.h.
7032 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7033 SCM_BACKTRACE_INDENT.
7035 * eval.c: Added new debug options `maxdepth' and `indent'.
7037 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
7039 * print.h: Added selector SCM_PRINT_STATE.
7041 * print.c: New functions: scm_make_print_state,
7042 scm_free_print_state.
7044 * print.h: Added declarations for scm_make_print_state,
7045 scm_free_print_state.
7047 * debug.c (scm_m_start_stack): New acro.
7049 * debug.h: Small cleanup.
7051 * init.c (scm_boot_guile_1): Moved scm_init_debug below
7054 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

7074 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
7075 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
7076 declare functions with prototypes. (Patch thanks to Marius
7079 More prototype-related changes from Marius Vollmer:
7080 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7081 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7082 * ports.h (ptobfuns): Added prototypes. This means some casting in
7084 * fports.c: Added casts for initializations, since the functions
7085 are defined to take FILE * as their stream argument, not SCM.
7086 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7087 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7088 to `char *str_data' to conform to prototype.
7090 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7092 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7094 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7096 * stime.c, stime.h: use SCM_P method.
7098 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7100 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7101 be given at least two arguments. Insist that lst's last element
7102 be a list, but don't make any requirements of its predecessors.
7104 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7106 * eval.c (scm_nconc2last): Revert last change; there seems to be
7107 other stuff going on here.
7109 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7111 * eval.c (scm_nconc2last): Make sure that each element of lst
7112 (which is a list of argument lists, except for the tail) is a
7113 proper list, i.e., finite and terminated by '().
7115 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7117 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7120 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7121 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7124 * vectors.c (scm_make_vector): Fill vectors with the undefined
7125 value, to help make Guile Scheme code more portable to other
7128 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7129 * symbols.h, tags.h: Doc fixes.
7131 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7133 * async.c (scm_take_signal): Doc fixes.
7135 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7137 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7138 want to subtract it from the modulus; we just want to leave it
7141 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7143 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7146 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7148 * throw.c (scm_catch_apply): Finished implementation of
7151 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7153 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7155 (scm_init_filesys): set "i/o-extensions" feature.
7158 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7160 * Makefile.in (root.o): Correct dependencies.
7162 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7164 * Makefile.in: Added dependency entry for root.o.
7166 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
7167 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
7169 * init.c (scm_start_stack): Set initial root continuation number
7172 * procs.c: New function: scm_thunk_p.
7174 * procs.h: Added declarations of scm_thunk_p.
7176 * root.c: Renamed `call-with-new-root' -->
7177 `call-with-dynamic-root'.
7178 (cwdr): Removed allocation of new root state. This should be done
7179 separately by use of scm_make_root.
7180 (scm_apply_with_dynamic_root): New function: Does what it
7181 sounds like. Needed when spawning threads.
7183 * root.h: Added member last_debug_frame to root state.
7184 Added #include "libguile/debug.h"
7186 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
7187 arguments. The motivation is that code in root.c needs catch
7188 functionality, and we want to avoid code duplication.
7189 New functions: scm_catch, scm_lazy_catch. These are wrappers for
7190 scm_catch_apply. scm_lazy_catch is intended to introduce catch
7191 handlers that run without popping the stack into the dynwind
7194 * throw.h: Added prototypes for scm_catch_apply and
7197 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7199 * root.h (scm_root, scm_set_root): Decouple thread support details
7200 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
7201 SCM_SET_THREAD_LOCAL_DATA.
7203 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
7204 and tortoise scanning loop.
7206 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
7208 * Makefile.in: Rebuild dependencies.
7210 * libguile.h: #include "libguile/print.h" before "smob.h", since
7211 the latter uses the print_state structure.
7213 * throw.c (scm_ithrow): Use the correct variable when checking to
7214 see if a given element of scm_dynwinds is a valid catch.
7216 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
7217 structure, abort; don't just silently ignore the garbage.
7219 * _scm.h: #include "print.h" here, since it seems to be used just
7221 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
7222 strports.c, unif.h: Don't #include "print.h".
7224 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7226 * feature.h (scm_loc_features): Removed external declaration.
7227 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
7229 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7231 * feature.c (scm_init_feature): Added threads feature (needs to be
7232 initialized here, since features doesn't exist when
7233 scm_init_threads is called).
7235 * libguile.h: Added #include "libguile/../threads/threads.h".
7236 (This is a kludge to get thread support working. This should be
7239 * configure.in, acconfig.h: Added flags for thread support.
7241 * scmsigs.c: Define `signal' to be `pthread_signal' if using
7244 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
7245 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
7248 * _scm.h: Added conditional #include "threads.h"
7250 * __scm.h (SCM_ASYNC_TICK): Added call to macro
7251 SCM_THREADS_SWITCHING_CODE.
7253 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
7254 allocate the basic dynamic root object.
7255 (scm_boot_guile): Added call to scm_init_root.
7257 * root.c, root.h: Added root smob.
7258 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
7259 functions: Implements dynamic roots mostly according to spec in
7260 SCM manual. Main difference is that the second argument is a
7261 throw handler rather than an error "thunk".
7263 * root.h: Added declaration of scm_init_root.
7265 * root.c: Added #include "genio.h", #include "smob.h", #include
7266 "pairs.h", #include "throw.h", #include "dynwind.h", #include
7268 (scm_init_root): Added #include "root.x".
7270 * throw.c: Added #include "stackchk.h"
7271 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
7272 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
7273 can be used in scm_call_with_new_root; Added reenabling of stack
7274 checking when catching a throw.
7276 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
7278 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
7280 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
7281 element is not found, as per R4RS.
7283 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7285 * list.c: Doc fixes throughout.
7287 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7289 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7290 declare the char * to be const. Avoids a warning in rgx.c.
7292 * ports.h: spelling fix.
7294 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7297 * load.c (scm_sys_try_load_path): throw an error if file not found
7298 (like it says it in NEWS).
7300 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7302 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7303 PROPS slot to '(), not #f; it's an empty alist.
7305 * throw.h, throw.c: Use SCM_P instead of #if hair.
7307 Remove special support for uncaught throws; see throw.c for
7309 * throw.c (uncaught_throw): New function.
7310 (scm_ithrow): Call uncaught_throw if we don't find a throw
7311 target; don't mess with scm_bad_throw_vcell.
7312 (scm_bad_throw_vcell): Variable deleted.
7313 (scm_init_throw): Don't initialize it.
7315 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7318 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7320 * numbers.c (scm_istr2int): If the number is short (as most
7321 numbers are), just call scm_small_istr2int to deal with it.
7322 (scm_small_istr2int): New function, created by un-#ifdefing the
7323 non-bignum version of scm_istr2int and renaming it.
7325 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7327 * load.c (scm_sys_try_load): don't check whether value returned
7328 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7329 Change the Scheme name from %try-load to primitive-load.
7331 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7332 Can avoid passing a message, allowing it to be derived in the
7333 error handler (e.g., if we want to throw to the key both from
7336 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7338 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7339 references now have a new appearance which is more compact and
7340 also gives a clue about what the target of the reference is.
7341 By setting parameters in the print state, more fancy printing can
7342 be achieved. This is used by the (not yet commited) backtrace
7345 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7347 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7350 * print.c: Added #include "struct.h". Removed function
7353 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7354 scm_iprin1. Removed prototype for scm_prlist.
7356 * arbiters.c (prinarb),
7357 async.c (print_async),
7358 debug.c (prindebugobj, prinmemoized),
7359 eval.c (prinprom, prinmacro),
7360 filesys.c (scm_fd_print, scm_dir_print),
7362 mallocs.c (prinmalloc),
7363 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7364 smob.h (scm_smobfuns),
7365 srcprop.c (prinsrcprops),
7367 unif.c, unif.h (scm_raprin1, rapr1),
7368 variable.c (prin_var): Changed argument `int writing' to
7369 `scm_print_state *pstate'.
7371 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7372 that it will be called before scm_init_print.
7374 * print.c (scm_prin1): Print states are now allocated when calling
7375 scm_prin1 and then passed around to all printing functions as an
7376 argument. A cache `print_state_pool' enables reuse of print
7378 (scm_make_print_state): New function.
7379 (scm_iprin1): Adaption to print states.
7380 (scm_iprlist): An initial "hare and tortoise" scan brings down
7381 time complexity to O (depth * N). (Better time complexity will be
7382 achieved when the printing code is completely rewritten.)
7384 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7386 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7387 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7388 it gets done whether or not the cache variable has a value.
7390 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7392 Distinguish #f and ().
7393 * __scm.h: #undef SICP.
7394 * pairs.h (SCM_EOL): Delete this definition, equating it with
7396 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7397 the value it used to have. Doc fixes, too.
7399 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7401 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7402 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7403 Lord's implementation of structs, allowing for tail arrays as
7404 described in the manual. Also fixed some bugs. (Both the interface
7405 and the implementation should be improved.)
7407 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7409 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7410 People who whish to see the source can do `(print-enable 'source)'.
7411 Removed #ifdef DEBUG_EXTENSIONS.
7413 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7415 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7416 integer (assuming for now accepting an integer is a good thing).
7418 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7419 %S will be used instead for write'ing arguments.
7421 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7422 asserts. fix a few other asserts.
7423 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7424 scm_uniform_vector_ref, scm_array_set_x,
7425 scm_dimensions_to_unform_array): change args in
7426 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7427 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7428 scm_substring_fill_x): likewise.
7429 gsubr.c (scm_gsubr_apply): likewise.
7430 eval.c (SCM_APPLY): likewise.
7432 * eval.c (4 places): replace scm_everr with lgh_error or
7435 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7436 scm_memory_error): new procedures.
7437 scm_everr: deleted. can use scm_wta, dropping first two args.
7438 scm_error: convert NULL subr to SCM_BOOL_F.
7440 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7443 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7446 * error.c, error.h: new error keys: scm_arg_type_key,
7447 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7449 scm_wta: reimplement using lgh_error instead of scm_everr.
7451 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7453 * gdbint.c: scm_lread now has one more argument.
7455 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7456 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7457 loading source from non-file ports, which, e. g., happens when
7458 using the Emacs interface).
7460 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7463 * read.c: Added code for recording of positions of source code
7464 expressions; New functions: recsexpr, scm_lreadrecparen;
7465 _scm_make_srcprops --> scm_make_srcprops
7466 (scm_flush_ws): Removed updating of positions counters. This work
7467 is already done by scm_gen_getc
7469 * read.h: Added prototype for scm_lreadrecparen
7471 * print.c: Added #include "alist.h"
7473 * eval.c: Added #include "hash.h"
7475 * eq.c: Added #include "ramap.h"
7477 * options.c: Documentation fixes.
7479 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7480 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7481 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7482 --> scm_make_srcprops
7484 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7485 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7486 function calls in the definition of the whash access macros.
7488 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7490 * init.c (scm_boot_guile): Add level of indirection to
7491 scm_boot_guile_1() to ensure that stack base pointer is properly
7492 initialized. There was no guarantee that variable i was the
7493 highest/lowest variable on stack (i.e. the call frame of
7494 scm_boot_guile was not completely protected from gc).
7496 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7498 * ports.h (scm_port_table): put back file_name, it will be used to
7499 support debugging. Undo related changes in fports.c, ioext.c,
7502 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7504 * ports.h (scm_port_table): remove file_name member for now, it seems
7506 * fports.c (scm_open_file): don't set file_name in PTAB.
7507 (prinfport): don't use file_name in PTAB.
7508 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7509 * ports.c (scm_add_to_port_table): don't intialize file_name.
7510 (scm_port_file_name): remove for now.
7511 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7513 * fports.h (scm_mkfile): prototype deleted.
7514 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7516 * debug.c, unif.c: use scm_out_of_range instead of
7517 wta for range errors (ASSERT still needs work).
7519 * error.c, error.h (scm_out_of_range): new procedure.
7521 * error.c, error.h (scm_out_of_range_key): new key.
7523 * posix.c (scm_sync): #else was missing.
7525 * error.c, error.h: append _key to names scm_num_overflow and
7528 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7529 of consing an empty list.
7530 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7531 of macros, saves code and string space.
7532 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7533 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7534 lower case. Rename scm_syserror_m to scm_syserror_msg.
7535 error.h: prototypes for new procedures.
7537 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7539 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7541 * error.c, error.h: setup scm_num_overflow key.
7543 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7544 Remove definition of SCM_OVSCM_FLOW.
7546 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7548 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7549 explicit message and args.
7551 * error.c, error.h, __scm.h: change system_error_sym to
7554 * error.c (system_error_sym): remove leading %% from the Scheme name
7557 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7559 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7561 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7562 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7563 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7564 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7565 renamed. (These were introduced by unsupervised name
7568 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7570 * print.c: Added code for detection of circular references during
7571 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7572 a hook for printing of closures (accessible via print options).
7573 This leads to a split of calls to scm_iprin1 into two classes:
7574 elementary print operations (e. g. the code which prints a smob)
7575 still use scm_iprin1 while top level calls (like scm_display) use
7576 scm_prin1. scm_prin1 begins by clearing the data structure used
7577 to record reference information.
7579 * print.h: Added declarations of scm_prin1 and scm_prlist.
7581 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7583 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7585 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7587 * error.c (err_head): scm_iprin1 --> scm_prin1
7589 * debug.c: Adjusted header comment.
7593 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7595 * strerror.c: Doc fix.
7597 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7599 * gdbint.c (gdb_read): Now possible to run during GC.
7600 (unmark_port, remark_port): New functions.
7602 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7604 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7605 of allocating a new string object. Also, increase size by
7606 the factor 2 instead of 1.5.
7608 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7610 * __scm.h (SCM_P): Corrected to run under traditional C.
7612 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7615 * async.c: Calls to scm_sysintern corrected.
7617 * async.h (scm_async_clock): Redundant declaration removed.
7619 * continuations.c (scm_dynthrow): Redundant declaration removed.
7621 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7622 Definition typos corrected.
7624 * debug.h: Missing declarations of functions in debug.c added
7627 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7628 Missing declarations to functions in eval.c added.
7630 * filesys.c: Possibly uninitialized variable rv.
7632 * gc.h (scm_object_addr, scm_unhash_name): Missing
7633 declarations of functions defined in gc.c added.
7635 * genio.c: Possible typos str_data -> wstr_data. ???
7637 * genio.c: Possibly unintended shadowing of local variable
7638 `int c' (gotos out of scope of inner `c'). ???
7640 * init.c: Uninitialized `SCM last' may be used.
7642 * ioext.h: (scm_sys_isatty_p): Typo.
7644 * list.h (scm_list_head): Missing prototype for function in
7647 * numbers.c (scm_two_doubles): Changed from extern to static
7648 (is used only within numbers.c).
7650 * numbers.h: Repeated declarations removed.
7652 * ports.h (scm_close_all_ports_except): Declaration for the
7653 function defined in ports.c added.
7655 * posix.h: Missing declarations added.
7657 * procs.h (scm_make_subr_opt): Missing declaration added.
7659 * socket.h (scm_sys_gethost): Missing declaration added.
7661 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7663 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7664 Missing declarations added.
7666 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7668 * struct.c: Uninitialized variable `SCM answer' may be used.
7670 * unif.c (l2ra): Declaration prototype.
7672 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7673 defined in ramap.c).
7675 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7676 Redundant declarations removed (they are in ramap.h).
7678 * variable.h (scm_make_udvariable,
7679 scm_make_undefined_variable): Declaration corrected to
7680 correspond variable.c.
7682 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7683 Missing declarations added.
7685 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7687 * Makefile.in (distclean): Don't forget to delete fd.h.
7689 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7691 * fd.h.in, tags.h: Trivial cleanups.
7693 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7694 marksweep.h just declared functions from gc.c.
7695 * gc.h, libguile.h: Don't #include "marksweep.h".
7696 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7697 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7698 dependencies updated.
7700 * libguile.h: Don't #include "files.h"; it's been deleted.
7702 * files.c (scm_sys_delete_file): Moved to filesys.c.
7703 File is now empty; deleted.
7705 * filesys.c: scm_sys_delete_file is now here. Remove
7706 #if's; they seem to rely on remnants of an old portability
7707 regimen. If the problems come up again, solve them properly,
7708 using autoconf. Specifically: Don't test M_SYSV, and #define
7709 remove to be unlink if it's #defined; don't use remove just
7710 because HAVE_STDC_HEADERS is #defined.
7711 * filesys.h: Add declarations for scm_sys_delete_file.
7712 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7713 files.o, files.h, files.c, and files.x.
7714 * init.c: Don't #include "files.h", and don't call scm_init_files.
7716 Use SCM_P instead of PROTO; the latter intrudes on the user's
7718 * params.h: Deleted; definition of SCM_P moved to...
7719 * __scm.h: ... here, where it replaces PROTO macro.
7720 * libguile.h, smob.h: Don't #include "params.h".
7721 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7722 smob.h: Fix prototypes accordingly.
7723 * Makefile.in: Update dependencies.
7724 (inner_h_files): Remove params.h.
7726 * gc.c: #include "gc.h"; every module should include its header,
7727 to let the compiler cross-check the declarations against the
7730 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7731 simpos.h: #include "libguile/__scm.h".
7733 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7735 * init.c: Don't forget to #include smob.h and init.h.
7736 * Makefile.in: Dependencies updated.
7738 * smob.h: Use PROTO instead of #if __STDC__.
7740 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7742 * __scm.h: Doc fixes.
7744 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7745 <angles>; this allows `make depends' to work properly.
7747 * libguile.h: #include smob.h and pairs.h before the others; they
7748 define typedefs used by other headers.
7750 C files should #include only the header files they need, not
7751 libguile.h (which #includes all the header files); the pointless
7752 recompilation was wasting my time.
7753 * Makefile.in (all .o dependency lists): Regenerated.
7754 * libguile.h: Don't try to get a definition for size_t here...
7755 * __scm.h: Do it here.
7756 * _scm.h: Since this is the internal libguile header, put things
7757 here that all (or a majority) of the libguile files will want.
7758 Don't #include <libguile.h> here; that generates dependencies on
7759 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7760 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
7761 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

7860 * stackchk.h: #include "libguile/debug.h",
7862 * print.h, read.h: #include "options.h", since everyone who uses
7863 either of these files will need that.
7865 * smob.h: #include "ports.h", "genio.h", and "print.h", since
7866 anyone who uses this file will need them to define the smob
7867 printing functions. Also, get markers.h, since people will need
7868 to #define the mark functions.
7870 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
7871 * ports.h: ... to here.
7873 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7874 don't rely on archaic C default type rules.
7876 * fports.h: #include "libguile/ports.h", since you need that in
7877 order to parse this.
7879 * genio.h: #include "libguile/print.h", because you need that to
7880 parse this; don't bother #including "ports.h", since print.h gets
7883 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7885 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7886 this; it's now a reference to an element of *scm_root.
7888 * debug.h: Don't #include "options.h"; the compiler won't be able
7889 to find that once the headers are installed; instead, #include
7890 "libguile/options.h".
7891 * gc.h: Same, with marksweep.h.

7893 * scmhob.h: Same, with _scm.h.
7894 * smob.h: Same, with params.h.
7896 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
7897 C files; there's no need for this, and it forces recompilations
7900 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
7902 * error.c (scm_error): declare scm_error_callback.
7904 * error.h: prototype for scm_error_callback.
7906 * __scm.h: define lgh_error.
7907 (SCM_SYSERROR): redefine using lgh_error.
7909 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
7911 * error.c (scm_error): new procedure.
7913 * error.h: prototype for scm_error.
7915 * Makefile.in (install): install scmconfig.h from the current
7916 directory, not $(srcdir).
7918 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7920 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7921 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7922 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

7928 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7929 vports.h, weaks.h: #include "libguile/__scm.h", not
7930 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
7931 dependencies are within libguile properly.
7933 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7935 * Makefile.in (.c.x): Simplify; there's no need to run this rule
7936 when scmconfig.h doesn't exist.
7938 * load.c (scm_sys_try_load): Correct spelling.
7940 * feature.c (scm_loc_features): Make this static.
7942 * Makefile.in (libpath.h): Omit trailing slash from path. We
7943 shouldn't require it of users, so why put it here?
7945 Move code to initialize and search %load-path from ice-9 to C
7946 code, so we can use the load-path to find the ice-9 boot code;
7947 this makes it easier to run Guile without installing it. See
7948 corresponding changes in guile/Makefile.in.
7949 * feature.c: Move stuff concerned with the load path to load.c.
7950 (scm_compiled_library_path): Deleted.
7951 Don't #include libpath.h here.
7952 * feature.h: Don't mention scm_compiled_library_path.
7953 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
7954 <sys/stat.h>, and <unistd.h> (if present).
7955 (R_OK): #define if the system hasn't deigned to.
7956 (scm_loc_load_path): New variable.
7957 (scm_init_load_path, scm_sys_search_load_path,
7958 scm_sys_try_load_path): New functions.
7959 (scm_init_load): Initialize scm_loc_load_path to point to the
7960 value cell of the Scheme %load-path variable.
7961 * load.h: Add declarations for scm_sys_search_load_path,
7962 scm_sys_try_load_path.
7963 * init.c: Call scm_init_load_path.
7964 * Makefile.in (feature.o, load.o): Dependencies updated.
7966 * load.c, load.h: Rewrite using PROTO macro.
7968 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7970 * gc.c (scm_cellp): New function: C predicate to determine if an
7971 SCM value can be regarded as a pointer to a cell on the heap.
7973 * gc.h: Added declaration of scm_cellp.
7975 * gdb_interface.h: New file: The GDB interface header from the GDB
7978 * gdbint.c: New file: GDB interface.
7980 * gdbint.h: New file: GDB interface.
7982 * libguile.h: Added #include <libguile/gdbint.h>.
7984 * init.c (scm_boot_guile): Added scm_init_gdbint.
7986 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
7987 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
7988 found if object files and source are kept separate).
7990 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
7992 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
7994 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
7996 * configure.in: Don't substitute the values of TCL_SRC_DIR and
7997 TK_SRC_DIR; they're not relevant any more.
7999 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8000 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8002 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8004 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8005 search path, so we can find the <libguile/MUMBLE.h> headers.
8007 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8009 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8010 implicit in the .c.o rule.
8011 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8014 Put the library path in a header file, instead of passing it on
8015 the command line in every compilation.
8016 * Makefile.in (libpath.h): New target.
8017 (feature.o): Depend on libpath.h.
8018 (clean): Delete libpath.h.
8019 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8020 * feature.c: ... #include "libpath.h" here.
8021 * .cvsignore: Ignore libpath.h.
8023 Don't install the unwashed masses of Guile header files in the
8024 main #include path; put most of them in a subdirectory called
8025 'libguile'. This avoids naming conflicts between Guile header
8026 files and system header files (of which there were a few).
8027 * Makefile.in (pkgincludedir): Deleted.
8028 (innerincludedir): New variable; this and $(includedir) are enough.
8029 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8030 (installed_h_files): Divide this up. Now this variable lists
8031 those header files which should go into $(includedir) (i.e. appear
8032 directly in the #include path), and ...
8033 (inner_h_files): ... this new variable says which files appear in
8034 a subdirectory, and are referred to as <libguile/mumble.h>.
8035 (h_files): List them both.
8036 (install): Create innerincludedir, not pkgincludedir. Put
8037 the installed_h_files and inner_h_files in their proper places.
8038 (uninstall): Corresponding changes.
8039 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8040 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8041 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
8042 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
8043 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
8044 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8045 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8046 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8047 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8048 vports.h, weaks.h: Find __scm.h in its new location.
8049 * __scm.h: Find scmconfig.h and tags.h in their new locations
8050 (they're both "inner" files).
8052 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8054 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8056 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8058 * posix.c: Doc fixes.
8060 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8062 * socket.c: Don't include a prototype for inet_aton; just use a
8063 K&R style declaration, to avoid warnings but minimize the chance
8064 of conflicts with the system.
8066 On NextStep, <utime.h> doesn't define struct utime, unless we
8067 #define _POSIX_SOURCE before #including it.
8068 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8069 * acconfig.h: New comment text for above CPP symbol.
8070 * configure.in: Call it.
8071 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8073 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8075 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8076 testing for __EMX__.
8078 * posix.c: #include <libc.h>, if it exists.
8080 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8081 don't even know if the latter exists.
8083 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8084 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8085 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8087 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8089 (scm_init_posix): Use them when initializing the Scheme constants
8092 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8094 * Makefile.in (libdir, includedir, bindir): Use the
8095 autoconf-supplied values, instead of deriving them ourselves.
8096 (pkgincludedir, datadir, pkgdatadir): New variables.
8097 (install, uninstall): Put the header files in a special
8098 subdirectory, not in the main search path.
8100 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8101 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8103 * Makefile.in (IMPLPATH): Deleted; never used.
8105 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8106 on the Tcl/Tk source any more.
8107 (INCLUDE_CFLAGS): Remove references to the above.
8109 * Makefile.in (version.o): Corrected dependencies.
8111 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8113 * libguile.h: #include "version.h"
8115 * init.c (scm_boot_guile): Call scm_init_version.
8116 * gscm.c (gscm_run_scm): Call scm_init_version.
8118 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8119 GUILE_VERSION): AC_DEFINE these.
8120 (acconfig.h): #undef the above symbols.
8122 * Makefile.in (libobjs): Add version.o.
8123 (installed_h_files): Add version.h.
8124 (c_files): Add version.c.
8125 (gen_c_files): Add version.x.
8126 (version.o): New rule.
8127 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8128 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

8137 weaks.o): Add version.h to dependency lists.
8138 (markers.o): Remove duplicate rule.
8140 * version.h: New file.
8142 * version.c: New file.
8144 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8146 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8147 array; use it appropriately. Since GCC is quite happy to
8148 subscript functions, it never warned us about this; we should use
8149 -Wpointer-arith in the future. I guess we never tested
8152 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8154 * socket.c: Doc and copyright fixes.
8156 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8158 * debug.c: Fixed and improved gdb support.
8160 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8162 * socket.c: Added declaration of inet_aton to avoid compiler
8163 warning. (Hope this solution is correct.)
8165 * stime.c: Added declaration of ftime. (This is missing in
8168 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
8170 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8172 * Makefile.in (c_files): add strerror.c.
8174 * strerror.c: new file from Emacs' sysdep.c.
8175 maybe configure should also check for sys_errlist.
8177 * configure.in (AC_REPLACE_FUNCS): add strerror.
8179 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8181 * debug.c (scm_init_debug): Added initialization for
8182 scm_evaluator_traps.
8184 * debug.h, debug.c: Various name changes.
8185 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
8186 "debug-options-interface". See commentary in options.c.
8188 * options.h, options.c: Options now have documentation strings.
8189 Also added a long explanatory commentary.
8191 * eval.c, print.h, print.c, read.h, read.c: Modifications to
8194 * gscm.c, init.c, root.c, throw.c: Bug fixes:
8195 last_debug_info_frame is now updated in all cases.
8197 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
8200 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8202 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
8203 Added option STACK_CHECKING.
8205 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8207 * Makefile.in: Added {debug,options,srcprop}.{h,c}
8209 * __scm.h: Removed symbols for debugging support.
8211 * acconfig.h: Added symbols for debugging support.
8213 * configure.in: Added user option for debugging support.
8214 --enable-debug will include the debugging code into libguile.a.
8216 * continuations.c (scm_make_cont): Enlarged the #if 0 around
8217 scm_relocate_chunk_to_heap.
8219 * debug.c: New file: low-level debugging support. It also
8220 includes support for debugging with gdb. (The extensions to gdb
8221 are written by Per Bothner at Cygnus.)
8223 * debug.h: New file: low-level debugging support.
8225 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
8226 argument pairs. Extensive modifications to the debugging
8227 evaluator. Added "SECTION:" commentaries to clarify what happens
8228 when, during double compilation. Renamed EVALIMP --> EVALIM.
8229 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
8230 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
8231 the beginning of the file. New procedure: scm_unmemocopy.
8232 Added some global state variables needed by the debugging
8233 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
8234 check_entry, check_apply, check_exit, debug_options and
8235 evaluator_traps. New acro: undefine.
8237 * eval.h: Renamed EVAL --> XEVAL.
8239 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
8240 --> scm_make_weak_key_hash_table.
8242 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
8243 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
8245 * libguile.h: Conditionally include debug.h
8247 * objprop.c (scm_object_properties, scm_set_object_properties_x):
8248 scm_object_properties shouldn't return handle. `handle' now gets
8249 initialized in scm_set_object_properties_x. scm_object_properties
8250 doesn't any longer create an entry in scm_object_whash.
8252 * options.c: New file: handling of run time options.
8254 * options.h: New file: handling of run time options.
8256 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
8258 * print.c: New procedure: scm_print_options
8260 * print.h: Defines for print options.
8262 * read.c: New procedure: scm_read_options
8264 * read.h: Defines for reader options.
8266 * root.h: Added scm_source_whash among scm_sys_protects.
8268 * srcprop.c: New file: source properties.
8270 * srcprop.h: New file: source properties.
8272 * throw.c (jbsmob): Jump buffers are now correctly allocated.
8273 (Bug found by A. Green.)
8275 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8277 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8279 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
8281 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8283 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8284 and should be called by the final client.
8286 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8288 * gc.h: Use the PROTO macro when declaring functions.
8289 * gc.c: Use the PROTO macro when declaring static functions.
8290 Remove the CPP hair around function definitions.
8292 * gc.c (scm_init_storage): Initialize scm_asyncs.
8294 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8295 preprocessor symbol; "__scm.h" is where it might get #defined.
8296 * __scm.h: Similar: #include <scmconfig.h> before testing
8299 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8301 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8303 * init.c (scm_boot_guile): Add init_func argument; call
8304 (*init_func) instead of calling scm_appinit; it's ucky to
8305 hard-code names for the user's procedures.
8306 * init.h (scm_boot_guile): Adjust declaration.
8308 * __scm.h (PROTO): New macro, for declaring functions with
8311 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8312 eliminate all the __STDC__ conditionals.
8313 (scm_boot_guile): Add declaration.
8314 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8315 Remove __STDC__ conditionals around function definitions; the
8316 declarations in init.h will provide the same information, more
8319 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8320 complain about it in the error message; the error message is
8321 adequate without that note, and there's nothing the user can do
8324 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8326 * Makefile.in (ancillary): Drop def.sed.
8328 * posix.c (scm_init_posix): Use numeric values, rather than
8329 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8330 F_OK. The symbols aren't available on some systems, and I'm
8331 pretty sure their values are fixed by common widespread practice.
8332 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8334 More functions unavailable on some systems.
8335 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8336 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8338 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8339 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8340 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8341 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8342 stub that signals an error as the #else.
8344 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8346 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8348 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8350 * unif.c: include ramap.h.
8352 * read.c (endif): case_insensative_p renamed case_insensitive_p.

8356 * ports.c: include sys/ioctl.h.
8358 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8360 * configure.in: check for sys/ioctl.h.
8362 * ports.c: include <malloc.h> not "malloc.h".
8364 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8366 * fports.c: remove ttyname and tmpnam declarations.
8368 * posix.c: fewer ttyname declarations.
8370 * fports.c: include <string.h> not "string.h".
8372 * init.c, ioext.c: include string.h and unistd.h.
8374 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8376 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8377 genio.c, simpos.c, vports.c: include string.h.
8379 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8381 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8383 (scm_addr_buffer_size): change type from scm_sizet to int.
8384 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8385 from scm_sizet to int.
8387 * error.c: include unistd.h.
8389 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8392 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8394 * __scm.hd, def.sed: deleted.
8396 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8398 Changes for NeXT, suggested by Robert Brown.
8399 * configure.in: Call AC_TYPE_MODE_T.
8400 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8401 NeXT. Put header file list in alphabetical order.
8402 * configure, scmconfig.h.in: Regenerated.
8403 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8405 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8408 * acconfig.h: New file, providing documentation for the CPP
8409 symbols defined in configure.in
8410 * acconfig-1.5.h: Removed; superceded by the above.
8412 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8414 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8416 * fports.c (scm_open_file): don't return #f, throw error.
8418 * ioext.c (fileno): renamed from %fileno.
8419 (soft-fileno): deleted.
8421 * ports.c (scm_port_revealed): don't need to check for -1 from
8423 (scm_set_port_revealed_x): return unspecified, not #f.
8425 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8427 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8429 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8431 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8433 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8435 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8436 This is necessary on Ultrix, and doesn't hurt portability.
8438 * Makefile.in (dist-dir): New target, implementing a new dist system.
8439 (installed_h_files): Put in alphabetical order.
8440 Remove duplicate entries for markers.h and unif.h.
8441 (c_files): Remove duplicate entries for markers.c.
8442 (ancillary): Renamed from anillery; all uses changed. Remove
8443 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8444 Remove all the ../doc/* files; doc/Makefile.in handles that.
8446 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8448 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8449 every if must have an else, or else the whole command has a
8450 non-zero exit code whenever the if's condition is false.
8452 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8454 * posix.c: include string.h.
8456 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8458 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8461 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8462 Remove leading % from scheme names.
8463 Do not return error values, call SCM_SYSERROR or similar.
8465 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8467 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8469 * struct.c (scm_init_struct): new file.
8471 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8473 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8474 (scm_list_head): added list-head for rapidly chopping argument
8475 lists off of longer lists (and similar).
8477 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
8479 * objprop.c (scm_object_property): assq the cdr of the whash
8480 handle for obj, not the handle itself.
8482 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8484 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8485 weak hash tables last of all marking to avoid an obscure gc bug.
8486 WARNING: circular lists stored in a weak hash table will hose us.
8488 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8490 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8491 new functions similar to scm_substring_move_left_x and
8492 scm_substring_move_right_x.
8494 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8496 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
8499 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
8501 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8503 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8505 * strports.c (scm_strprint_obj): convenience function. C for
8506 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8508 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8509 removed to a separate library
8511 * init.c (scm_boot_guile): copied from guile-tcl.c.
8512 Initialization specific to tcl interpreters removed.
8514 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8516 * ports.c (scm_ports_prehistory): size malloced here doesn't
8517 matter so long as it is non-0 (got rid of "* 4").
8519 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8521 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8522 since its definition was bogus).
8524 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8526 * mallocs.[ch]: back again (for rx at least).
8528 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8530 * ports.c: removed functions relating to the mapping between ports
8531 and descriptors. (That stuff is unix-specific and should be collected
8532 in a separate library).
8534 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
8535 (Tom Mckay@avanticorp.com)
8537 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
8539 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8540 handled correctly (SCM_FREEP was applied to them) -- test for
8541 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
8542 being overwritten with #f. (brown@grettir.bibliotech.com)
8544 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
8546 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs

8549 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
8551 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak

8556 * list.c (scm_last_pair): map '()=>'()
8558 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>

8561 Generalized assoc and hash-table functions.
8562 Factored pairs.c into multiple files.
8564 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
8566 * gscm.c (gscm_run_scm): got rid of objprop.
8568 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
8570 * genio.c (scm_getc):
8571 NOTE: fgetc may not be interruptable.
8573 * procprop.c (scm_stand_in_scm_proc):
8574 NOTE: don't use a alist here.
8575 (scm_set_procedure_properties_x): fix type checking throughout this file.
8577 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
8579 * ports.c (scm_remove_from_port_table): adjust scm_mallocated

8585 * vports.c (scm_make_soft_port): allocate a port table entry
8586 (possibly triggering gc) before setting the tag of the corresponding
8589 * pairs.c (scm_delq_x): never throw an error.
8591 * vectors.c (scm_make_vector): made the default vector fill argument
8592 into '() (much more useful than the previous value, "#unspecified")
8594 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
8596 * ports.c (scm_add_to_port_table): Added fields
8597 to port table entries: file_name, line_num, col.
8598 Update these in open_file, gen_getc and gen_ungetc.
8599 Added procedures to access those fields.
8601 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
8603 * procs.c (scm_make_subr_opt): new entry point for making
8606 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
8608 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
8610 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
8612 * numbers.c (scm_exact_p): This function no longer
8613 implements "integer?".

8617 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
8618 (scm_gc_stats): return an assoc of useful data. Replaces "room"
8619 and the stats reporting formerlly built into repl.

8622 GC statistics keeping moved to gc.c.
8623 Other statistics keeping can be done from Scheme.
8624 REPLS are now written in Scheme.
8626 Wed Feb 21 10:28:53 1996 Tom Lord <lord@beehive>
8628 * cnsvobj.c (gscm_is_gscm_obj): new file for old functions (icky

8631 * throw.c (scm_ithrow): Unwind up to the right catch during a throw!
8633 * error.c (scm_init_error): init system_error_sym here, not in repl.c.
8635 * feature.c (scm_compiled_library_path): moved here from repl.c.
8636 This file is for stuff relating specifically to Scheme libraries
8639 * eval.c (scm_m_define): don't give warning about redefinition, don't
8642 NOTE: this should throw a resumable exception with parameters --
8643 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
8645 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.
8647 * error.c: scm_warn eliminated.

8659 between the call to procedurep and use.
8661 * error.c (scm_everr):
8663 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
8666 * strports.c: don't reveal the port's string to the caller
8667 because it changes size.
8669 (stputc stwrite): check/change the strings length with interrupts
8672 * objprop.c (scm_set_object_property_x &c): use the generic
8673 hashing functions and be threadsafe.
8675 * eval.c (scm_unmemocar): do this operation in a thread-safe way.
8676 (per suggestion jaffer@gnu.ai.mit.edu).
8678 * mbstrings.c (scm_multi_byte_string): guard against argument list
8681 * strings.c (scm_make_string): loop cleanup
8683 * unif.c (scm_vector_set_length_x): scm_vector_set_length_x no longer
8686 * weaks.c (scm_weak_vector): guard against argument list
8689 * variable.c (scm_builtin_variable): check for/make a built-in
8692 * vectors.c (scm_vector): while filling the new array,
8693 guard against a list of fill elements that grows after
8694 the vector is allocated.

8697 functions. hash, hashq, hashv, hashx.
8699 * tags.h: made wvect an option bit of vector.

8703 * symbols.c: made the basic symbol table operations atomic.
8705 * root.c &c.: collected stack-specific global state.
8706 linum/colnum etc *should* be port-specific state.
8708 * struct.c (scm_init_struct): init the first struct type during
8709 initialization to fix a race condition.
8711 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
8712 object, not in a global.
8713 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
8715 * throw.c (_scm_throw): Pass throwval on the stack, not in a global
8716 (suggested by green@cygnus, jaffer@gnu.ai.mit.edu)
8718 * *.[ch]: namespace cleanup. Changed all (nearly) exported CPP
8719 and C symbols to begin with SCM_ or scm_.

8730 * async.c: New support for interrupt handlers.
8732 Thu Feb 15 11:39:09 1996 Tom Lord <lord@beehive>
8734 * symbols.c (scm_string_to_symbol et al.): number of tweaky changes to
8735 set the multi_byte flag correctly in symbols. This is wrong.
8736 intern_obbary_soft and msymbolize should take an extra parameter.
8737 Also, weird multibyte symbols don't print correctly.
8738 The weird symbol syntax is also a bit bogus (emacs doesn't quite
8741 Tue Feb 13 11:39:37 1996 Tom Lord <lord@beehive>
8743 * symbols.c (scm_string_to_obarray_symbol): obarray == #f means
8744 use the system symhash. == #t means create an uninterned symbol.
8746 Wed Feb 7 09:28:02 1996 Tom Lord <lord@beehive>
8748 * strings.c (scm_make_shared_substring): build'em.
8749 It might better to keep a table of these and use one
8750 less cons-pair per shared-substring.
8752 Tue Feb 6 17:45:21 1996 Tom Lord <lord@beehive>
8754 * strings.c (scm_string_shared_substring): create shared

8802 * error.c (def_err_response): (int)scm_err_pos => (long)scm_err_pos
8803 Eliminate a (presumed) warning on some systems.
