1 1999-09-11 Jim Blandy <jimb@savonarola.red-bean.com>
3 * strop.c (scm_substring_move_x): Signal an error if start1
4 doesn't come before end1. (Thanks to Karoly Lorentey).
6 * numbers.c (scm_istr2flo): Don't call SCM_INEXP without first
7 calling SCM_NIMP. (Thanks to Karoly Lorentey).
9 * version.c (scm_libguile_config_stamp): Deleted. See
10 corresponding change to ../ice-9/boot-9.scm.
11 * version.h: Delete prototype.
12 * Makefile.in: Regenerated.
14 1999-09-11 Gary Houston <ghouston@easynet.co.uk>
16 * filesys.c (scm_directory_p): new procedure "directory?" Returns
17 a boolean indicating whether its argument is a directory
18 port as returned by opendir (thanks to Dirk Herrmann for the
21 1999-09-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
23 * backtrace.c (display_frame_expr): Don't print a newline.
24 (display_frame): Print the newline here instead.
25 (display_backtrace_body): Don't print "Backtrace:".
26 (scm_backtrace): Print "Backtrace:" here instead.
28 1999-09-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
30 * procs.c (scm_setter): Signal WTA if handed an entity or operator
33 * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
34 primitives. (Thanks to Greg Badros);
35 (scm_hook_to_list): New primitive; Hooks are now smobs.
37 1999-09-08 Gary Houston <ghouston@easynet.co.uk>
39 * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value
40 of #f for the 10th vector element to avoid an exception
41 seen by Bernard Urban.
42 (scm_mktime): unneeded ASSERT removed.
44 1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
46 * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
49 * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
51 1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
53 * numbers.c: Converted comparison operations to dispatch on
54 generic if args don't match.
56 * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
58 1999-09-06 James Blandy <jimb@mule.m17n.org>
60 * guile-snarf.c: Deleted. Snarfing should respect CPP
61 conditionals, so it needs to actually run CPP. Bleah.
63 1999-09-05 James Blandy <jimb@mule.m17n.org>
65 Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
66 * guile-snarf.in: Be sure to exit with an error if CPP does.
67 * Makefile.am (.c.x): Delete the .x file and exit with an error
68 status if guile-snarf exits with an error status.
69 * Makefile.in: Regenerated.
71 * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
72 scm_makekey, which doesn't exist any more. Guess nobody's using
75 * guile-snarf.c: New implementation of guile-snarf, meant to be
76 more robust than the shell script. I think it's complete, but I
77 haven't tested it at all, and I haven't changed the build process
78 to actually use it. We should compare its output against that of
79 the existing shell script, for all source files.
81 * guile-snarf.c (parse_args): Abort if we haven't handled some
84 1999-09-03 James Blandy <jimb@mule.m17n.org>
86 * load.c (scm_search_path): If the filename has any extension at
87 all, ignore the entire list of extensions. Also, don't check whether
88 the file is accessible. If the file exists, accessible or not, we
89 should return it. Inaccessible files should cause an error later.
90 (Thanks to Keisuke Nishida for the suggestions.)
92 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
94 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
95 atexit not available. (sunos4.1.4 needs it.)
97 1999-09-01 James Blandy <jimb@mule.m17n.org>
99 I take it all back --- bcopy does handle overlapping source and
100 destination areas correctly. At least on every system I could
101 find. But it is better to use AC_REPLACE_FUNCS than to introduce
102 new CPP conditionals.
103 * memmove.c: New file, implementing memmove in terms of bcopy.
104 * scmconfig.h.in: Regenerated.
106 Allocators should use the `void *' type for generic pointers.
107 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
108 argument and return types.
109 * gc.h: Corresponding changes to prototypes.
112 1999-08-31 James Blandy <jimb@mule.m17n.org>
114 * numbers.c (scm_init_numbers): Claim to support the `complex'
115 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
117 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
118 find (ice-9 boot-9) when Guile was compiled in a separate
119 directory from the source. (Thanks to Rodney Brown.)
120 * Makefile.in: Regenerated.
122 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
123 table lengths by the size of a single element when growing the
124 table. (Thanks to Bill Schottstaedt.)
126 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
128 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
129 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
130 since that cuts down the time for type dispatch by 50%.
132 1999-08-30 James Blandy <jimb@mule.m17n.org>
134 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
135 not a correct substitute for memmove, because it doesn't handle
136 overlapping source and destination areas on many platforms.
137 Overlaps are the primary reason to use memmove in the first place.
138 * ports.c (scm_ungetc): Same.
139 * strop.c (scm_substring_move_x): Same.
141 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
143 * gc.c (scm_init_storage): Skip registration of cleanup on systems
144 which lack atexit. (Is it important that cleanup is made
145 properly? Maybe we should replace all `exit' with `scm_exit' and
148 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
149 scm_struct_free_standard, scm_struct_free_entity): Declared to
150 return scm_sizet instead of size_t.
152 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
153 there on sunos4.1.4.)
155 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
157 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
158 Account for the case when second argument is unbound.
160 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
161 (Thanks to Karoly Lorentey.)
163 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
164 isn't present. (Thanks to Suzuki Toshiya.)
166 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
169 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
172 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
173 Bernard Urban and Ian Grant.)
175 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
176 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
177 change in the representation of entities and operators.)
179 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
181 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
182 don't allocate zero bytes (thanks to Bill Schottstaedt).
184 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
186 * procs.c (scm_setter): Converted to use generic dispatch.
188 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
191 * load.c (scm_search_path): Don't try extensions which already are
192 present at the end of the filename.
193 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
195 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
197 Cleanup and simplification of generic method dispatch.
198 Also, the quadruple representation of entity and operator
199 procedures has been replaced with single.
201 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
203 * print.c (scm_isymnames): Removed #@hash-dispatch.
205 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
206 from eval.c; Support 0 arity methods.
207 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
208 (scm_apply_generic_env): Removed.
209 Replaced slots proc0-3 with procedure.
211 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
212 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
213 SCM_OPERATOR_PROCEDURE.
214 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
215 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
217 * struct.c, struct.h: Replace 4 procedure slots with one.
218 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
220 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
223 * eval.c (scm_sym_args): Removed.
224 (SCM_CEVAL): Simplified entity application.
225 Moved dispatch code to objects.c.
227 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
229 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
231 * sort.c (closureless): Use scm_eval_body.
233 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
234 with a symbol as last form was first called normally and then via
235 `map' or some other mechanism using primitive apply, an ILOC was
238 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
240 This change extends the representation of primitive procedures
241 with more data fields, e.g. a place for documentation and true
242 procedure properties.
244 * procs.c, procs.h (scm_subr_entry): New type: Stores data
245 associated with subrs.
246 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
247 SCM_SUBR_DOC): New macros.
248 (scm_subr_table): New variable.
249 (scm_mark_subr_table): New function.
251 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
253 * gc.c (scm_gc_mark): Don't mark subr names here.
254 (scm_igc): Call scm_mark_subr_table.
257 This change implements a scheme for letting a generic work as a
258 shadow for a primitive procedure. If the primitive procedure
259 can't dispatch on its arguments, control is left over to the
260 generic. Normal wrong type arg errors will be generated until the
261 user has hung the first method on the primitive.
263 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
265 * procs.c, procs.h (scm_subr_p): New function (used internally).
267 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
269 * objects.c, objects.h (scm_primitive_generic): New class.
271 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
273 * print.c (scm_iprin1): Print primitive-generics.
275 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
276 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
278 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
279 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
280 primitives). NOTE: This means that it is now *required* to use
281 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
282 obscured representation that will be removed in the future anyway,
283 so backward compatibility is no problem here).
285 * numbers.c: Converted most numeric primitives (all but bit
286 comparison operations and bit operations) to dispatch on generic
290 Better support for applying generic functions.
292 * eval.c, eval.h (scm_eval_body): New function.
294 * objects.c (scm_call_generic_0, scm_call_generic_1,
295 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
299 Optimization of the generic function dispatch mechanism.
301 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
302 called scm_memoize_method instead of doing a second lookup.
304 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
309 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
310 scm_sysintern so that the binding connected with the subr name
311 isn't cleared when we give set = 0.
314 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
316 More transparent handling of ports with print states.
318 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
319 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
320 instead of a pair of a port and a print state. We'll need to cons
321 once extra in scm_printer_apply but the type system will be
322 cleaner, it will mix better with GOOPS, and, it will be even more
323 transparent to the user.
325 * print.c (scm_get_print_state): New procedure: Given an output
326 port, return the print state associated to it in the current print
327 chain, if one exists;
328 (scm_port_with_print_state): New procedure: Associate a
329 print-state with a port.
330 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
331 (scm_printer_apply): Wrap port and pstate as a smob;
332 (print_state_printer): Removed.
334 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
336 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
339 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
340 testing (otherwise the port-print-state trick won't be transparent
341 to the user; one example where this caused problems was in the
342 (ice-9 format) module).
344 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
346 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
347 SCM_UNSPECIFIED instead of the set value.
349 1999-08-20 James Blandy <jimb@mule.m17n.org>
351 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
353 * ports.h (enum scm_port_rw_active): New enum, containing
354 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
355 zero). The debugger knows about enums, but doesn't know about
357 (typedef scm_port): Declare rw_active member to be an enum
359 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
361 * ports.c (scm_add_to_port_table): Same.
362 * strports.c (st_flush, st_end_input): Same.
364 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
365 scm_must_realloc, and scm_done_malloc as appropriate.
367 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
369 * sort.c (quicksort): Added condition to protect the algorithm
370 from crashing the interpreter if the less predicate is buggy.
372 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
374 * fports.c (fport_write): fix line-buffering mode again.
375 (scm_open_file): recognise 'l' for line-buffering.
376 (scm_setvbuf): recognise _IOLBF for line-buffering.
378 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
380 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
383 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
386 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
388 * fports.c (fport_write): use memcpy instead of strncpy, in case
389 the data contains NUL.
391 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
393 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
395 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
396 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
397 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
398 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
399 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
400 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
401 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
402 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
403 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
404 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
405 scm_sym_ as prefix for symbols.
407 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
409 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
410 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
411 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
412 scm_sym_atcall_cc): Made global.
414 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
416 * eval.c (scm_sym_args): Made global.
418 * objects.c (scm_set_object_procedure_x): Disallow setting of
419 procedures for pure generic functions.
421 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
423 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
424 Scheme name from lseek to seek, but lseek was added recently so
425 it shouldn't be a big problem.
426 * ports.c, gdbint.c, ioext.c: changed callers.
428 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
430 * fports.c (fport_input_waiting): if select is used, return 1
431 instead of whatever FD_ISSET expands to. maybe it will be useful
432 to interpret the value from the input_waiting ptob procedure as a
433 lower bound on the number of bytes available.
435 * Mikael asked for a few names to be changed...
437 * ports.c (scm_make_port_type): take the write procedure as the
438 second argument instead of the flush procedure.
439 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
440 fflush -> flush, read_flush -> end_input, fclose -> close,
441 fill_buffer -> fill_input, ftruncate -> truncate,
442 input_waiting_p -> input_waiting.
444 * ports.c (end_input_void_port): was read_flush_void_port.
445 (scm_set_port_end_input): was scm_set_port_flush_input.
446 (scm_set_port_flush): was scm_set_port_write.
447 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
448 (scm_end_input): was scm_read_flush.
449 (scm_fill_input): was scm_fill_buffer.
450 (scm_flush): was scm_fflush.
451 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
452 (fport_end_input): was local_read_flush.
453 (fport_flush): was local_fflush.
454 (fport_close): was local_fclose.
455 (fport_truncate): was local_ftruncate.
456 (fport_seek): was local_seek.
457 (fport_free): was local_free.
458 (fport_fill_input): was fport_fill_buffer.
459 * strports.c (st_end_input): was st_read_flush.
460 (st_truncate): was st_ftruncate.
461 * vports.c: (sf_flush): was sfflush.
462 (sf_close): was sfclose.
463 (sf_fill_input): was sf_fill_buffer.
465 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
468 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
470 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
471 forms now contain the expressions to be dispatched upon instead of
472 depending on a surrounding lambda or let; Generic function
473 dispatch has been optimized; `apply' on a generic function now
474 works a little bit strangely. It uses a trick so that the type
475 dispatch code in SCM_CEVAL can be reused.
477 * objects.h, objects.c (scm_apply_generic_env): Added (used by
479 (scm_operator_p): Added.
480 (scm_sym_atdispatch): Added.
481 (scm_set_object_procedure_x): Modified to handle the new style
483 (scm_object_procedures): New debugging procedure.
485 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
487 * eval.c, eval.h (scm_sym_args): Added.
489 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
491 * feature.c, feature.h (scm_c_run_hook): Added.
493 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
494 cdrxnoap and loopnoap instead of begin and loop.
496 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
498 * ports.c (scm_putc, scm_puts),
499 * unif.c (scm_uniform_array_write): use scm_lfwrite.
500 * ports.c (scm_putc): change type of first argument from int to char.
502 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
504 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
505 SCM_IM_HASH_DISPATCH.
507 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
508 (scm_si_redfined, scm_si_hashsets): Moved.
510 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
511 flag which combines type and status info so that the class
512 redefinition protocol has zero cost during normal execution.
514 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
516 * ports.h (scm_ptob_descriptor): include a write procedure again.
517 it's more efficient for unbuffered fports (e.g., sockets.)
519 * ports.c (scm_puts): use ptob->write.
520 * vports.c (scm_make_sfptob): set write proc in ptob.
521 * strports.c (scm_make_stptob): set write proc in ptob.
522 * ports.c (write_void_port): new procedure.
523 * vports.c (sf_write): new procedure.
524 * ports.c (scm_lfwrite): use ptob->write.
525 * strports.c (st_write): new procedure.
526 * fports.c (fport_write): new procedure.
527 (scm_make_fptob): set write in ptob to fport_write.

540 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
541 code, particularly an unnecessary test (len != size, where len ==
542 size). (Was this leftovers from debugging code, or have I missed
545 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
546 size. (Thanks to James Dean Palmer.)
548 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
549 (Thanks to Lorentey Karoly.)
551 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
553 * eval.c (scm_m_expand_body): Use scm_cons_source.
555 * struct.c (scm_print_struct): Use vtable name.
557 * print.c (scm_init_print): Set name of print state type.
559 * stacks.c (scm_init_stacks): Set name of stack type.
561 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
563 * eval.c (SCM_CEVAL): Removed old implementation of internal
566 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
568 * debug.c, debug.h (scm_reverse_lookup): Added.
569 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
570 internal procedure definitions; Don't use scm_i_inner_name.
572 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
575 * eval.h: Added prototypes for multi language support functions.
577 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
578 improper lists in the low-level representation, since that will
579 cause a begin to be prepended at macro expansion.
581 * eval.c (scm_cons_source): Version of cons which copies source
582 properties from an existing cell.
583 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
585 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
586 procedure source before calling scm_unmemocopy instead of faking
589 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
591 Ported `internal defines' fix from SCM. Original ChangeLog entry:
593 1998-07-09 Radey Shouman <radey@colorage.com>
595 * eval.c (ceval_1): Modifications to allow rewriting of interal
596 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
597 body of which it is the CAR is macro expanded by m_expand_body,
598 which rewrites internal DEFINE.
600 (m_expand_body): Added.
602 (m_macroexp1): Added argument to control error checking:
603 m_expand_body may speculatively expand forms in the wrong
604 environments. Made argument number checks conditional on
607 (m_body): Added, error checks bodies and inserts the ISYM tokens.
609 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
612 (m_cond): (m_case): (m_quote): Modified to avoid destructively
613 changing their argument forms. Since m_expand_body
614 speculatively macro expands forms the process must be
617 (m_ident_eqp): Fixed to use proper environment.
619 (renamed_ident): Added DEFER_INTS_EGC.
621 Added prototypes for static functions.
627 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
628 is false, do not produce an error for unbound variables, return a
629 pointer to cell_undef instead.
631 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
635 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
636 destructively changing their argument forms. Since m_expand_body
637 speculatively macro expands forms the process must be reversible.
639 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
640 SCM_IM_LET introduced by named lets.
642 (scm_m_letstar): Use scm_m_body instead of bodycheck.
644 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
645 scm_letrec. scm_letrec1 does not check for a null binding and
646 takes an additional argument to specify the ISYM of the body. Use
647 scm_m_body instead of bodycheck.
649 (scm_m_let): Use scm_m_body instead of bodycheck.
651 (scm_m_expand_body, scm_macroexp): New.
653 (unmemocopy): Account for ISYMs introduced by scm_m_body.
655 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
656 check=1. Throw error for internal defined that have not been
657 rewritten by scm_m_expand_body.
659 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
660 Removed prototype for SCM_APPLY.
662 * tags.h: Added extern declaration of scm_isymnames.
664 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
666 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
668 * lang.c: New file: Beginning of multi-language support.
670 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
672 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
673 (scm_dynamic_wind): Added argument checking for the after guard so
674 that we don't add garbage on the dynwind chain.
675 (scm_swap_bindings): Added.
677 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
678 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
679 (scm_isymnames): New isyms for multi-language support.
681 * eval.c (scm_nil, scm_t): New symbols.
682 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
683 forms for multi-language support.
685 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
687 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
689 Renamed functions in the random function library interface
690 from scm_i_XXX --> scm_c_XXX.
692 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
694 * ports.c (scm_putc): fix line-buffering.
696 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
698 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
699 scm_set_ptob_XXX --> scm_set_port_XXX.
701 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
703 * ports.c, ports.h (scm_make_port_type): New interface for
704 creation of port types (replaces scm_newptob). Just as for the
705 smobs, we need to separate the internal representation of smob
706 types from the interface, so that we easily can add new fields and
707 rearrange things without caring about backward compatibility.
708 This change was forced by the need in GOOPS to create classes
709 representing port types.
710 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
711 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,

713 scm_set_ptob_input_waiting_p): New setters.
714 (scm_newptob): Rewritten to use scm_make_port_type. For backward
716 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
717 (scm_prinport): Removed.
718 (scm_port_print): Added.
719 (scm_print_port_mode): Added.
720 (void_port_ptob, print_void_port, close_void_port, noop0):
721 Removed. Removed #include "genio.h" Added #include "objects.h",
724 * fports.c (prinfport): Moved code from ports.c.
726 (scm_fptob): Removed. Instead use new interface.
727 (scm_make_fptob): Added. (Need to create basic ports in a
728 specific order in ports.c.)

731 (scm_make_stptob): Added.
733 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
734 (scm_make_sfport): Added.
736 * filesys.c (scm_dir_print): Don't use the port printing code.
737 Instead provide specific directory printer.
739 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
741 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
744 * smob.c (scm_smob_print): Handle non-existing type name nicely.
745 Removed #include "genio.h"
747 * objects.c (scm_make_port_classes): New function ptr.
749 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
751 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
753 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
754 allow the 1st argument to be a fdes or filename as well as a
755 port (as in the filesys.c version).
757 * filesys.c (scm_truncate_file): removed.
759 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
761 * readline.c, readline.h: Removed.
763 * objects.c, objects.h (scm_port_class): Added.
764 (scm_class_of): Look up port class in scm_port_class.
765 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
766 SCM_INOUT_PCLASS_INDEX): Added.
769 * Makefile.am: Removed genio.c, genio.x.
773 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
775 * init.c: Make sure that scm_post_boot_init_modules is called only
776 once. (Important when using a dumped image.; Thanks to Bernard
779 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
781 * guardians.c (scm_guardian_zombify): Separate scanning for
782 zombies from marking the pairs of the free list.
784 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
785 use the macros. (Thanks to Michael Livshin.)
787 * eval.c (scm_m_lambda): Let bodycheck check the body of the
788 lambda. Let your sins be purified by the blood of the lambda.
789 (Thanks to Eric Hanchrow.)
791 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
792 (Thanks to Valdis Kletnieks.)
794 Fixes for EMX from Mikael Ståldal.
796 * filesys.c: #include <io.h>, if we have it.
797 * scmconfig.h.in: Regenerated.
799 * stime.c (ftime): Delete declaration for this function --- let
800 the system supply it.
802 Cleanups from John Bley.
804 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
806 * gsubr.c: Don't include "gsubr.h" twice.
808 Cleanups for compilation on Irix 6, from David Kaelbling.
810 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
811 regex_t pointer. This is what the callers have, mostly.
812 (scm_regexp_exec): Don't forget to pass the `rx' argument to
813 scm_regexp_error_msg.
815 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
816 int. That way, if we get a warning on this line, it's more likely
817 that we're really missing bits we care about.
819 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
822 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
823 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
824 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
825 cast at all is more appropriate in every case. At the moment, we
826 assume everywhere that SCM is an integral type anyway.
828 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
830 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
831 read_pos after scm_fill_buffer.
833 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
836 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
837 fports.c (fport_fill_buffer): implement the interface change.
839 * ports.c (scm_fill_buffer): interface change: no longer increments
840 read_pos past the character that's returned. it seems clearer to
841 leave it to the caller to decide what to do (thanks Jim).
843 * vports.c (sf_fill_buffer): put the read char into the buffer
844 as well as returning it.
846 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure

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

897 (scm_call_with_output_string, scm_strprint_obj): use
898 scm_strport_to_string.
899 used SCM_INUM0 instead of SCM_MAKINUM (0) in a few places.
901 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
903 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)

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

1000 * dynl-dl.c (sysdep_dynl_link): Added parenthesis around the
1001 trinary conditional in order for the flag computation to be
1004 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1006 * struct.c, struct.h:
1008 In order to support different kinds of deallocation, a destructor
1009 slot has been added to struct vtables. This allows for structs
1010 containing pointers to other memory blocks.
1012 (scm_struct_i_free): New hidden struct slot. Holds destructor for
1013 instances to this vtable.
1014 (scm_struct_free_0): New destructor: Doesn't deallocate data.

1085 around the condition of an `if', `while', etc., even if the
1086 condition is a macro invocation that expands to something
1087 surrounded by parens. It's more readable.
1089 * eval.c (scm_map, scm_for_each): Verify that all arguments are
1090 proper lists, and of the appropriate lengths.
1091 (check_map_args): New function. (Thanks to Greg Harvey for the
1094 1999-06-19 Michael Livshin <mike@olan.com>
1096 * guardians.c (guardian_t): `next' - new field to be used for
1097 chaining the live guardians in a single-linked list during the GC
1099 (GUARDIAN_NEXT): convenience macro to access the `next' field.
1100 (guardians, guardians_size, n_guardians): deleted.
1101 (first_live_guardian, current_link_field): new globals used to
1102 point to the head of the live guardian list and current `next'
1103 field, respectively.
1104 (g_mark): append the guardian to the live guardian list.
1105 (scm_guardian_gc_init): zero the live guardian list.
1106 (scm_guardian_zombify): iterate through the live guardian list.
1108 (Applied by Jim Blandy.)
1110 1999-06-16 Jim Blandy <jimb@savonarola.red-bean.com>
1112 * gc.c (scm_mallocated): Just make this signed.
1113 (scm_igc): Check for underflow by seeing if this is negative.
1115 * gc.h (scm_mallocated): Fix declaration.
1116 (Thanks to Greg Harvey.)
1118 * ports.h: #include <sys/types.h>, to get a definition for `off_t'.
1120 1999-06-15 Jim Blandy <jimb@savonarola.red-bean.com>
1122 * stime.c (bdtime2c): Initialize lt->gmtoff and lt->tm_zone from
1123 sbd_time. (Thanks to Eric Hanchrow.)
1125 Fix from Ken Raeburn <raeburn@raeburn.org>:
1126 * weaks.c (scm_make_weak_vector): Add another extra slot before
1127 vector contents, to be used only during garbage collection.
1128 * weaks.h (SCM_WVECT_GC_CHAIN): New macro to access it.
1129 * gc.c (scm_weak_vectors): Now a SCM instead of a SCM*, and now
1131 (scm_weak_size, scm_n_weak): Deleted.
1132 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
1133 vectors without allocating new storage during GC, using
1134 scm_weak_vectors as the head of the chain.
1135 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1136 instead of stepping through an array.
1137 (scm_gc_sweep): Update offset used to find start of weak vector to
1139 (scm_init_storage): Set scm_weak_vectors to EOL.
1141 Fix from Ken Raeburn <raeburn@raeburn.org>:
1142 * gc.c (already_in_gc): New variable.
1143 (scm_igc): Set and clear already_in_gc; abort if it's set at
1146 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
1148 Fix from Gary Houston:
1149 * fports.c (local_seek): Signal an error if the seek fails.
1150 * ports.c (scm_lseek): Don't check return value of port's seek
1151 function; it's its job to signal an error if there's a problem.
1153 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>
1155 * strports.c (scm_call_with_output_string): Don't include the
1156 extra character at the end of the string in the result.
1158 * ioext.c (scm_read_line): Switch to reading properly.
1160 * fports.c, fports.h, gc.c, gdbint.c, ioext.c, ports.c, ports.h,
1161 scmsigs.c, strports.c, vports.c: Install the sources which
1162 actually correspond to the changes described below. I got the
1163 ChangeLog entries and the patch from two different places...
1165 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1167 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1168 it shows up as terrible performance, as we GC constantly.
1170 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
1171 newline. A bit faster, and definitely hairier.
1172 (scm_read_line): Count newlines here instead.
1174 * strings.c (scm_take_str): New function.
1175 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
1176 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use
1177 scm_take_str, to avoid copying the string.
1179 Add some simple-minded support for line buffered ports.
1180 * ports.h (SCM_BUFLINE): New flag for ports.
1181 * init.c (scm_init_standard_ports): Request line-buffering on
1182 the standard output port.
1183 * ports.c (scm_mode_bits): Recognize 'l' as a request for line
1185 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1186 and there's a newline to be written, flush the port.
1188 Gary Houston's open-buffer port patches:
1190 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1192 * ports.c: (scm_lseek): clear buffers even if just reading current
1195 * fports.c (local_fclose): call local_fflush unconditionally.

1198 1999-04-25 Gary Houston <ghouston@easynet.co.uk>
1200 * ports.h (scm_port): make read_pos a pointer to const.
1201 strports.c: take care of rw_active and rw_randow.
1202 fports.c: scm_fport_drain_input: removed. do it all in ports.c.
1203 strports.c (scm_mkstrport): check that pos is reasonable.
1204 ioext.c (scm_ftell, scm_fseek): use lseek.
1205 (SCM_CLEAR_BUFFERS): macro deleted.
1206 ioext.c (redirect_port: use ptob fflush, read_flush.
1207 ports.h (scm_ptobfuns): add ftruncate.
1208 ports.c (scm_newptob): set ftruncate.
1210 ports.c (scm_ftruncate): new procedure.
1211 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.
1212 strports.c (st_seek, st_grow_port): new procs.
1213 fports.h (scm_port): change size types from int to off_t.
1214 ports.c (scm_init_ports): initialise the seek symbols here
1215 instead of in ioext.c.
1216 strports.c (scm_call_with_output_string): start with an empty
1217 string, so seek and ftruncate can be used.
1219 gdbint.c: adjust string port usage.
1221 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1223 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
1224 equivalent to fflush for the read buffer.
1225 * ports.c (scm_newptob): set read_flush.
1226 ports.c (void_port_ptob): set read_flush.
1227 fports.c (local_read_flush): new proc. add to ptob.
1228 strport.c (st_read_flush): likewise.
1229 vport.c (sf_read_flush): likewise.
1230 fports.h (struct scm_fport): remove random member. there's nothing
1231 left but fdes. leaving it as a struct to allow for future changes.
1232 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1233 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1234 ptob proc if the read buffer is filled.
1236 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1238 * ports.h (scm_port): add a rw_random member and replace
1239 reading and writing members with rw_active member.
1240 SCM_PORT_READ/SCM_PORT_WRITE: new values.
1242 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
1244 * ports.h (struct scm_port_table): add writing and reading members
1245 to replace write_needs_seek: it isn't good enough for non-fports.
1246 ports.c, ioext.c, fports.c: corresponding changes.
1247 (struct scm_port_table): give it a typedef and rename to scm_port.
1248 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
1249 corresponding changes.
1251 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
1253 * ports.c (scm_newptob): bugfix: set seek member.
1254 * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
1255 and generalised to all port types.
1257 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
1259 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
1260 signals (it was only being done for handlers installed from Scheme).
1261 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
1262 waiting for input caused an EINTR error from read.
1264 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
1266 * ports.h (struct scm_port_table): make all the char members
1267 unsigned, so they convert to int without becoming negative if large.
1269 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
1271 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
1272 with threads enabled. rename this procedure to
1273 fport_wait_for_input and take a port instead of a fdes.
1274 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
1276 * readline.c (scm_readline): Applied a patch from Greg Harvey to
1277 get readline support working again: use fdopen to get FILE objects.
1279 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
1281 * gc.c (scm_init_storage): install an atexit proc to flush the
1283 (cleanup): the new proc. it sets a global variable which can be
1284 checked by the ptob flush procs to avoid trying to throw
1285 exceptions during exit. not very pleasant but it seems more reliable.
1286 * fports.c (local_fflush): check terminating variable and if set
1287 don't throw exception.
1288 * CHECKME: that the atexit proc is installed if unexec used.
1290 * throw.c (scm_handle_by_message): don't flush all ports here.
1291 it still causes bus errors.
1293 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
1294 and move to ioext.c.
1296 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
1298 * ports.c (scm_char_ready_p): check the port buffer and call the
1299 ptob entry if needed.
1301 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
1302 ptob initialisers. use it in char-ready
1304 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
1306 * vports.c (sfflush): modified to write a char (since softports
1307 currently use shortbuf.)
1309 * fports.c (scm_standard_stream_to_port): moved to init.c and
1312 * init.c (scm_init_standard_ports): make stdout and stderr
1313 unbuffered if connected to a terminal. with stdio they
1314 were line-buffered by default.
1316 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
1319 * ports.h (scm_ptobfuns): change fflush return to void.
1320 change flush proc definitions.
1322 * strports.c (scm_call_with_output_string): get size from
1323 buffer instead of port stream.
1324 (st_flush): new proc.
1326 * ports.h (struct scm_port_table): added write_end member,
1327 as an optimisation. set it where write_buf_size is set.
1329 * ports.h (struct scm_port_table): change stream from void *
1330 back to SCM. SCM presumably must be large enough to hold a
1331 pointer (and probably vice versa but who knows.)
1332 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
1334 (scm_puts): rewritten
1335 * fports.c (local_ffwrite, local_fputs): removed.
1336 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)
1337 * vports.c (sfputc, sfputs, sfwrite) likewise.
1338 * ports.c (write_void_port, puts_void_port): removed.
1339 (putc_void_port, getc_void_port, fgets_void_port): likewise.
1341 * ports.c (scm_lfwrite): rewritten using fport.c version.
1343 * fports.c (local_fputc): deleted.
1345 * ports.c (scm_add_to_port_table): initialise write_needs_seek.
1347 * ports.h (scm_ptobfuns): add seek function pointer.
1348 * fports.c: set it to local_seek, new procedure.
1351 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
1352 use ptob for seek. take ptob instead of fport arg.
1354 * ports.h (struct scm_port_table): new member write_needs_seek,
1355 replaces reading member in fport struct.
1357 * vports.c (sfgetc): store the getted char into the buffer.
1358 rename to sf_fill_buffer and install it for fill-buffer in ptob.
1359 the Scheme interface is still a procedure that gets a char.
1360 (scm_make_soft_port): set up the port buffer (shortbuf).
1362 * fports.c (local_fgetc, local_fgets): deleted.
1363 * strports.c (stgetc): likewise.
1364 * ports.c: scm_generic_fgets: likewise.
1366 * ports.h (scm_ptobfuns): add fill_buffer.
1367 * ports.c (scm_newptob): assign it.
1368 * strports.c (scm_mkstrport): set up the buffer.
1369 put just the string into the stream, not cons (pos stream).
1370 (stfill_buffer): new proc.
1372 * ports.h: fport buffer moved into port table: to be
1373 used for all port types.

1382 scm_getpeername, scm_recv, scm_send, scm_recvfrom,
1384 use SCM_FPORT_FDES. use SCM_OPFPORTP not SCM_FPORTP.
1386 * posix.c (scm_getgroups): use SCM_ALLOW/DEFER_INTS.

1444 ports.c fports.c ioext.c posix.c socket.c net_db.c filesys.c:
1445 removed all uses of SCM_DEFER/ALLOW ints for now. they were mainly
1446 just protecting errno. some may need to be put back.

1451 *fports.c (print_pipe_port, local_pclose, scm_pipob): deleted.

1572 * strop.c (scm_substring_move_x): New function, which can handle
1573 arbitrary overlapping substrings.
1574 (substring-move-left!, substring-move-right!): These are
1575 now just synonyms for substring-move!.

1588 symbol is returned for any argument where the only difference
1589 between strings is in capitalization.

1601 1999-01-11 Greg Harvey <Greg.Harvey@thezone.net>
1603 * strop.h: fixed prototypes.
1605 * strop.c (scm_substring_move_left_x, scm_substring_move_right_x):
1606 changed to have 5 required args, rather than 2 required, and 3 required
1607 rest args. Also modified to allow str1 & str2 to overlap.

1646 linking crashes on NetBSD. (Thanks to Ken Raeburn.)
1648 1999-03-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1650 * numbers.c (isfinite): Define this macro if not defined: Return a
1651 non-zero value if X is finite. (From ISO C 9x standard.)
1652 (scm_inexact_to_exact): Bugfix: Don't pass NaNs to scm_dbl2big.
1653 (Thanks to Jon Trowbridge and Greg Harvey.)
1655 1999-03-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1693 * error.c (scm_wta): Pass SCM_LIST1 (arg) instead of SCM_EOL to
1694 scm_misc_error when pos is a string. This allows for dispatching
1695 arbitrary error messages with one argument via SCM_ASSERT:

1704 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1706 Most of this batch of changes is about how to deal with extended
1707 types when an object system is loaded into Guile. A nice object
1708 system is capable of representing Guile's types as class objects.
1710 For example, we want a regular expression to be of class <regex>.
1711 But regular expressions are smobs which aren't under direct
1712 control of the object system, so there has to be some mechanism
1713 which informs the object system that a new class should be created
1714 which can represent the smob type. I call this a "wrapper class".
1716 * objects.c: #include "smob.h";
1717 (scm_class_keyword): Removed. (Class is automatically created by
1719 (scm_smob_class): Array of smob classes indexed by smobnum.
1720 (scm_make_extended_class): "Plugin" function pointer for creation
1721 of wrapper classes for smob and struct types.
1722 (scm_class_of): Handle compiled closures. (Currently regarded as
1724 Use scm_smob_class to handle smob types;
1725 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1726 through scm_smob_class;
1729 * smob.c (scm_newsmob): Also create a wrapper class if
1730 scm_smob_class has been initialized.
1732 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1733 type code and smobnum.
1735 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1736 (scm_struct_table): Weak key table with auxilliary information for
1737 struct types. Currently used for names and wrapper classes.
1738 (scm_struct_ihashq): Hash function for structs.
1739 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1740 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1741 for accessing names of vtables. The record implementation in
1742 boot-9.scm currently uses the setter to record the name of record
1743 types. When the object system is initialized, it can use this
1744 information to create wrapper classes with suitable names.
1745 (scm_init_struct): Allocate scm_struct_table.
1746 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1747 (struct tags are a finite resource and we might want to restrict
1748 the use of tags to vtables only. E.g., Goops only uses tags for
1750 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1752 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1755 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1756 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1757 Used for access of struct table entries.
1759 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1760 (scm_hash_fold): New procedure. Used to process all entries in a
1761 hash table (in no particular order).
1763 Argh! For the umpteenth time I got compilation errors because of
1764 the "intuitive" name `kw'. This has to have an end:
1766 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1767 "kw" --> "keywords" everywhere.
1768 (I doubt that this will cause big compatibility problems since the
1769 application interface is unaffected.)
1771 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1773 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1775 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1776 column inums to native form.
1778 Improvement of backtraces: Introduces a new stack narrowing
1779 specifier, #t, for the inner cut. (See further in the comments in
1780 stacks.c:narrow_stack ().)
1782 * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
1783 (Used to flag certain system procedures which shouldn't turn up in
1786 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1787 modules which aren't "user" modules and the code of which
1788 shouldn't turn up in backtraces.)

1791 Extract the lookup closure from an environment.
1792 (scm_system_module_env_p): New function: Return non-#f if MODULE
1795 * stacks.c: #include "eval.h"; #include "procprop.h";
1796 (narrow_stack): Handle new narrowing specifier #t.
1798 * debug.c (scm_procedure_name): Use name property in the default
1801 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
1803 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1805 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1806 procedure throughout.
1808 * print.c (scm_iprin1): Removed extraneous space when printing
1809 procedure-with-setters.
1811 Entity and operator setter slots were introduced as a complement
1812 to the <procedure-with-setter> type in order to support entities
1813 and operators with setters in a reasonable and efficient way.
1814 * procs.c (scm_procedure, scm_setter): Handle entity and operator
1817 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

1827 1999-03-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1829 * objects.h (SCM_OBJ_CLASS_REDEF): New macro: Find class slots
1830 directly through the instance.
1832 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1834 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1835 scm_struct_i_flags instead of scm_vtable_index_layout!
1837 * list.c (scm_list_star): New procedure.
1839 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1920 SYMB now point to const.
1922 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1924 * print.c (scm_iprin1): Use scm_procedure_name instead of
1925 scm_procedure_property for compiled closures.
1927 * tags.h (scm_tc7_pws): New procedure type. Four representations
1928 for procedure-with-setters were considered before selecting this
1931 1. A closure where the CODE and ENV slots are used to represent
1932 the getter and a new SETTER slot is used for the setter. The
1933 original getter is stored as a `getter' procedure property. For
1934 closure getters, the CODE and ENV slots contains a copy of the
1935 getter's CODE and ENV slots. For subr getters, the CODE contains
1938 2. A compiled closure with a call to the getter in the cclo
1939 procedure. The getter and setter are stored in slots 1 and 2.
1941 3. An entity (i.e. a struct with an associated procedure) with a
1942 call to the getter in the entity procedure and the setter stored
1943 in slot 0. The original getter is stored in slot 1.
1945 4. A new primitive procedure type supported in the evaluator. The
1946 getter and setter are stored in a GETTER and SETTER slot. A call
1947 to this procedure type results in a retrieval of the getter and a
1948 jump back to the correct eval dispatcher.
1950 Representation 4 was selected because of efficiency and
1953 Rep 1 has the advantage that there is zero penalty for closure
1954 getters, but primitive getters will get considerable overhead
1955 because the procedure-with-getter will be a closure which calls
1958 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1959 <procedure-with-setter>, but together with rep 2 it suffers from a
1960 three level dispatch for non-GOOPS getters:
1962 cclo/struct --> dispatch proc --> getter
1964 This is because the dispatch procedure must take an extra initial
1965 argument (cclo for rep 2, struct for rep 3).
1967 Rep 4 has the single disadvantage that it uses up one tc7 type
1968 code, but the plan for uniform vectors will very likely free tc7
1969 codes, so this is probably no big problem. Also note that the
1970 GETTER and SETTER slots can live directly on the heap, using the
1971 new four-word cells.
1973 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,

2058 understand, when I ran automake in the top level directory. This
2059 may be contamination by Cygnus internal releases. If you re-run
2060 automake and this change gets reverted, don't worry about it.

2074 * numbers.c: Formatted according to Guile conventions;
2075 Renamed s_bignum --> scm_s_bignum.
2077 * random.c, random.h: New files: Random number support.
2078 Interface same as slib's.
2080 * Makefile.am: Added random.c, random.h, random.x.
2082 * init.c: #include "random.h";
2083 (scm_boot_guile_1): Call scm_init_random ().
2085 1998-12-23 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2087 * Makefile.am: New files: guardians.c, guardians.x, guardians.h
2089 * guardians.c, guardians.h (scm_make_guardian,
2090 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
2091 scm_get_one_zombie, scm_init_guardian): This is an implementation
2092 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
2093 David Eby (1993) "Guardians in a Generation-Based Garbage
2094 Collector" ACM SIGPLAN Conference on Programming Language Design
2095 and Implementation, June 1993 ftp://ftp.cs.indiana.edu
2096 /pub/scheme-repository/doc/pubs/guardians.ps.gz
2097 Author: Michael N. Livshin.
2099 * gc.h (SCM_MARKEDP, SCM_NMARKEDP): New macros.
2101 * gc.c (scm_igc): Call scm_guardian_gc_init and
2102 scm_guardian_zombify.
2104 * init.c (scm_boot_guile_1): Call scm_init_guardian.
2106 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2108 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
2111 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2113 Move the procedure slots of entities to invisible slots (so that
2114 we can have operator class objects which themselves are entities).
2115 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
2116 SCM_STRUCTF_ENTITY): New constants.
2118 * struct.c (scm_make_struct): Allocate "invisible" room for
2119 procedures if SCM_STRUCTF_ENTITY is set in vtable.
2121 * gc.c (scm_gc_mark): Mark entity procedures.
2123 * struct.c, struct.h (scm_alloc_struct): Renamed from alloc_struct
2125 (scm_struct_init): Renamed from init_struct and made global.
2127 * objects.h (SCM_ENTITY, scm_entity): Removed.
2128 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
2129 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
2131 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
2133 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
2134 of syntactic forms, similar to SCM_PROC.
2135 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
2136 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
2137 for the name symbols when needed.
2139 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
2141 * Makefile.in: Regenerated.
2143 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
2145 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
2146 take the address of _into; it might be a register. Just have
2147 scm_debug_newcell return the new cell.
2148 * gc.c (scm_debug_newcell): Just return the new cell, instead of
2149 taking the address of a place to store it as an argument.
2150 * gc.h (scm_debug_newcell): Change declaration.
2151 (Thanks to Greg Harvey.)
2153 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2155 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
2156 Replaces old names serial-array-copy! and serial-array-map!.
2158 * evalext.c (map-in-order): New name. Replaces serial-map.
2160 1998-12-05 Jim Blandy <jimb@totoro.red-bean.com>
2162 * smob.c (freeprint): New function.
2163 (freecell): Use it to print freed objects, for slightly easier
2166 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2168 * backtrace.c (display_frame): Made more robust. Doesn't throw an
2169 error if no source properties can be found for a frame. (Thanks
2170 to Christian Lynbech.)
2172 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2174 * objects.h: Removed slots direct_supers and direct_slots from the
2175 definitions of the rudimentary classes described by objects.h.
2177 * objects.c, objects.h (scm_entity_p): New procedure. Together
2178 with the predicates scm_procedure_p and scm_struct_p, this
2179 predicate makes it possible to differ between structs, entities
2182 * modules.c, modules.h (scm_resolve_module): New function.
2184 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2186 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
2187 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
2190 * objects.c (scm_entity_p): New procedure.
2192 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
2193 for asubrs, rpsubrs, lsubrs and lsubr_2s.
2195 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2197 * procprop.h (scm_i_procedure_arity): Added declaration.
2199 * procprop.c (scm_i_procedure_arity): Made global; New code to
2200 handle operators and entities.
2201 (scm_procedure_property): No need to call scm_procedure_p since
2202 scm_i_procedure_arity now does all necessary type checking.
2203 Added #include "objects.h".
2205 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2206 s_add_hook_x --> s_remove_hook_x.
2207 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
2208 Added #include "procprop.h"
2210 * feature.c, feature.h (scm_reset_hook_x): New procedure.
2211 (scm_make_hook): Optional argument defines number of arguments to
2213 (scm_make_named_hook): Take number of args as second arg.
2214 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2215 boot-9.scm for a while); First arg is the hook. The rest are
2216 arguments passed on to the hook procedures.
2218 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
2220 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2221 scm_logbit_p): Do the computation in ulongs. This is not as nice
2222 as doing it in bignums, but at least it's good enough for
2223 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2225 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2226 subexpressions. (Thanks to Charbel Jacquin.)
2228 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
2230 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
2231 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2232 (scm_make_named_hook): New function.
2234 * feature.c: Added #include "eval.h".
2236 * modules.c (scm_make_module): Beautify the module.
2238 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2240 * modules.c, modules.h: New files: C interface to modules. (This
2241 is necessary in order to interface the object system to Guile
2242 properly. The guts of these modules will be replaced by the new
2243 module system in the future.)
2245 * init.c: Added #include "modules.h"
2246 (scm_boot_guile_1): Call scm_init_modules.
2247 (invoke_main_func): Call scm_post_boot_init_modules.
2249 * Makefile.am: Added modules.c, modules.x, modules.h.
2251 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
2253 * procs.c: #include "objects.h"
2254 (scm_procedure_p): Return #t also on structs which are operators.
2256 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
2257 <operator-metaclass> and <entity-class> to <standard-class>,
2258 <operator-class> and <entity> in order to conform with STKlos
2261 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
2262 which isn't an operator.
2263 (SCM_APPLY): Ditto, but jump to badproc.
2265 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
2267 * eval.c (SCM_CEVAL): Allow structs implanted in code.
2268 Previously, structs implanted in code were interpreted as forms
2269 the operator of which was a gloc. We solve this by checking for
2270 the zero in the emulated vcell in the struct vtable. Since
2271 implanted structs always will look like forms with a gloc
2272 operator, execution will only be slowed down by maximally one
2273 extra test-and-branch per application.
2275 * evalext.c (scm_definedp): Removed check for isyms; Added a
2276 second optional argument: It is now possible to supply an
2277 evaluation environment in which to look for the symbol.
2279 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2281 * readline.c (scm_init_readline): Set
2282 rl_basic_word_break_characters. (Thanks to Ian Grant.)
2284 * coop.c (coop_condition_variable_wait): Removed
2285 (coop_condition_variable_wait_mutex): Folded logic of
2286 coop_mutex_unlock into coop_condition_variable_wait_mutex to
2287 prevent condvar signal lossage. Previously, another thread could
2288 start to run after unlocking the mutex but before putting the
2289 current thread on the wait queue. If that thread then would
2290 signal the first, the signal would be lost. (Thanks to Christian
2293 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2295 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
2298 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2300 * objects.c (scm_i_make_class_object): Renamed from
2301 make_class_object; exported; error checking moved to
2302 scm_make_class_object and scm_make_subclass_object.
2303 (scm_make_class_object, scm_make_subclass_object): Use
2304 scm_i_make_class_object.
2305 (scm_make_subclass_object): Let the subclass have same metaclass
2308 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2310 * debug.c (scm_debug_options): Bugfix: Set the value of
2311 scm_stack_checking_enabled_p after setting debug options;
2312 #include "stackchk.h". (Thanks to Richard Polton.)
2314 1998-11-13 Radey Shouman <rshouman@metro2000.com>
2316 * unif.c (scm_array_contents): removed unnecessary test for 0
2319 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2321 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
2322 Replaced by macro `collect' in boot-9.scm.
2324 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2326 * eval.c (scm_copy_tree): Copy source properties if existent.
2328 * debug.c (scm_start_stack): Copy source when evaluating. (If we
2329 don't, we may end up passing memoized source to a transformer.)
2331 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2333 * stack.c (get_applybody): Help function which lookups the first
2334 body form of the apply closure.
2335 (read_frames): Prevent the source of the first form of the apply
2336 closure from being recorded. This would only be confusing.
2338 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
2339 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
2341 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
2343 * stacks.c (read_frame): Bugfix: Removed lingering `else'
2345 (read_frames): Use SCM_MACROEXPP.
2347 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2349 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
2350 don't contain interesting information since all arguments are
2351 present in the frame which applies the compiled closure anyway.);
2352 Skip the transformer application frames.
2354 * print.c (scm_iprin1): Print gsubrs as primitives.
2356 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2358 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
2360 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
2361 that we can identify these in a backtrace. (This change doesn't
2362 introduce any significant speed penalty.)
2364 * eval.c: Added note about `serial-map' using scm_map.
2366 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2367 readline options. They should reside in their own options array.
2369 * readline.c, readline.h (scm_readline_options,
2370 scm_readline_opts): Moved readline options here.
2372 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2374 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2375 SCM_ROCHARS instead of SCM_CHARS.
2377 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2378 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2380 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2382 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2383 This is quite important since the latter clears the
2384 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2385 every single character read...
2387 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2389 * print.c (scm_iprin1): Removed suspect looking (and indeed
2390 malevolent) semicolon after test for user supplied closure print
2391 procedure. (Thanks to Telford Tendys.)
2393 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2394 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2395 starting to search the list. Removed call to sloppy_mem_check.
2397 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2398 procedures: Same as scm_delq_x et al, but delete maximally one
2401 * options.c (scm_options, scm_init_options): GC-protect option
2402 values of type SCM. (Thanks to Telford Tendys.)
2404 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2406 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2407 make sure that there always is a "real" scm_lookupcar.
2409 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2411 * read.c, read.h (scm_read_opts): New read options
2412 "history-length" and "history-file".
2413 (scm_read_options): Stifle history to history length.
2415 * readline.c (scm_read_history, scm_write_history): New procedures.
2417 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2419 * eval.h (scm_macro_eval_x): Removed declaration.
2421 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2422 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2423 Renamed and made global.
2425 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2426 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2428 * evalext.c, evalext.h: New files. Contain non-R5RS things
2429 having to do with evaluation.
2431 * evalext.c (scm_serial_map): New procedure: Version of `map'
2432 which guarantees that the procedure is applied to the lists in
2434 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2435 returns a list of the results of the body forms instead of the
2436 result of the last body form.
2437 (scm_definedp, scm_m_undefine): Moved from eval.c
2439 * evalext.h (scm_m_sequence_to_list): Added declaration.
2441 * macros.c, macros.h: New files.
2442 (scm_procedure_to_syntax, scm_procedure_to_macro,
2443 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2444 scm_macro_name, scm_macro_transformer): Moved from eval.c
2445 (scm_make_synt): Moved from eval.c
2447 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2449 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2452 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2454 * debug.c, print.c: Added #include "macros.h".
2456 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2458 This change adds the ability to use `unread-char' multiple times
2459 without interspersed reads and adds the new procedure
2460 `unread-string'. The change is optimized for the common case of
2461 unreading a single character. This is also the reason behind the
2462 choice to store characters in the port itself: in most cases no
2463 extra malloc is required.
2465 The amount of code in some macros in ports.h has been increased to
2466 the extent that they would fit better as C functions, but, since
2467 this code belongs to the port representation, such functions
2468 should be placed in ports.c which would cause calls back and forth
2469 between ports.c and genio.c. That is not good for performance.
2470 Also, keeping them as macros allows the compiler to do some
2471 optimizations which are needed to make the current interface
2472 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2474 One benchmark (Guile startup time) indicates an increase of
2475 loading speed of 1%. Another (reading (using `read') boot-9.scm
2476 10 times) shows no change in performance.
2478 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2479 made to find a beautiful solution.)
2481 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2482 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2483 character. (SCM_CLRDY clears all.)
2484 (SCM_N_READY_CHARS): New macro: Returns number of unread
2485 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2486 (struct scm_port_table): New fields: `entry' contains port table
2487 index, `cp' points to last unread char, `cbuf' is the buffer for
2488 unread chars, `cbufend' points after end of the character buffer.
2490 * ports.h, ports.c (scm_unread_string): New procedure.
2491 (scm_grow_port_cbuf): New function.
2493 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2495 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2496 to read unread characters. Use SCM_TRY_CLRDY instead of
2499 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2501 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2503 * genio.c, genio.h (scm_ungets): New function.
2505 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2508 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2510 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2511 declarations. (Thanks to Russ McManus.)
2513 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2515 * numbers.c (num2long): As a software archeologist, I'm proud of
2516 this finding! :) Preliminary dating suggests an almost 4 year old
2517 remnant from the SCM ancestor. The sample has been removed from
2518 the finding site and is now safely stored in the repository.
2520 * numbers.h: Removed prototype for num2long.
2522 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2524 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2525 array as second arg.
2526 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2527 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2528 * gh.h: Updated and added prototypes.
2530 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2532 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2534 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2536 * guile-snarf.in: Never generate an empty file. (Thanks to
2539 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2540 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2541 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2542 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2543 gh_new_procedure5_0): Specify argument types, to appease C++
2544 compilers. (Thanks to Brad Bowman.)
2546 Bug reports from Russ McManus:
2547 * guile-snarf.in: If the CPP environment variable is set, use that
2548 as the C preprocessor, instead of the preprocessor autoconf
2550 * snarf.h (SCM_PROC): Cast the function pointer passed to
2551 scm_make_gsubr, to satisfy C++.
2553 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2554 Use the handler passed, instead of ignoring it and using
2555 gh_standard_handler. (Thanks to Etienne Bernard.)
2557 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2559 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2562 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>

2582 * script.c (scm_compile_shell_switches): Define
2583 use-emacs-interface in the root module, so the repl code can see
2584 it. See today's change to top-repl in ice-9/boot-9.scm.
2586 * filesys.c (set_element, get_element): Make sure that `element'
2587 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2588 Boekemeier and Jorgen "forcer" Schaefer.)
2590 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2592 * chars.c (scm_charnames): In ASCII character name table, make
2593 newlines print as #\newline by default, not #\nl.
2595 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2596 alphabetical order. Oh thrills. But it helps me know how far
2597 along in the compilation I am.
2598 * Makefile.in: Regenerated.
2600 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2602 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2603 #bytes(...) to #y(...), and syntax for short vectors from
2604 #short(...) to #h(...). This may seem nutty, but, like the other
2605 uniform vectors, byte vectors and short vectors want to have the
2606 same print and read syntax (and, more basic, want to have read
2607 syntax!). Changing the read syntax to use multiple characters
2608 after the hash sign breaks with the conventions used in R5RS and
2609 the conventions used for the other uniform vectors. It also
2610 introduces complexity in the current reader, both on the C and
2611 Scheme levels. (The Right solution is probably to change the
2612 syntax and prototypes for uniform vectors entirely.)
2614 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2616 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2617 (Thanks to Jorgen "forcer" Schaefer.)
2618 * ports.h (SCM_NOFTELL): New flag.
2619 * fports.c (local_fgets): If it's set, use the generic fgets.
2620 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2622 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2624 * script.c (scm_compile_shell_switches): Add handling of -q switch
2625 (inhibit loading of user init file).
2626 (scm_shell_usage): Add usage text for -q switch.
2627 (scm_compile_shell_switches): Always load user init file first if
2628 it is loaded at all.
2630 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2632 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2633 and is now broken under NetBSD. I can't fathom what it's trying
2634 to do, so I've replaced it with something that I do understand,
2635 which seems to work, and which isn't broken on NetBSD. "Progress?
2636 You Decide." (Thanks to Perry Metzger.)
2638 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2639 signed/unsigned comparison.
2641 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2643 Warning fixes from Greg Harvey:
2644 * unif.c (scm_array_set_x): initializer for pos
2645 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2646 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2647 initializers for field_type, since EGCS so desparately wants to
2649 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2650 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2651 when GUILE_DEBUG is defined.
2652 * dynwind.h (scm_wind_chain): Same.
2653 * ports.h (scm_pt_size, scm_pt_member): Same.
2654 * print.h (scm_current_pstate): Same.
2655 * procs.h (scm_make_cclo): Same.
2657 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2659 Handle short and long long uniform arrays properly. (Thanks to
2661 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2662 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2663 scm_tc7_llvect (long long vectors).
2665 Change the way libguile and boot-9.scm are timestamped, to try to
2666 get rid of these spurious mismatch warnings. Now both
2667 libguile/versiondat.h and ice-9/version.scm are generated directly
2668 by the configuration process, rather than having version.scm
2669 generated directly, and libguile/versiondat.h generated by the
2670 Makefile, which is generated by configure. It seems that
2671 sometimes the Makefile would change, but versiondat.h depends on
2672 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2673 * Makefile.am (versiondat.h): Target removed; this is generated
2674 directly by the configure script now.
2675 (BUILT_SOURCES): Remove versiondat.h.
2676 * versiondat.h.in: New file, transformed by the configure script
2678 * Makefile.in: Regenerated.
2680 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2681 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2682 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2683 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2684 if we want to use them in a header file some day, we can. (Thanks
2685 to Michael Livshin.)
2687 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2688 SCM numbers, so we won't have rollover problems; the range of a
2689 signed long in milliseconds is about 25 days. (Thanks to Karl
2692 Don't redefine sleep and usleep; fix this problem now.
2693 * coop.c (sleep, usleep): Remove declarations; we don't use or
2694 redefine these any more.
2695 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2696 job of usleep and sleep in a thread-friendly way. We can use
2697 these in the rest of Guile. Define versions for systems both with
2698 and without iselect.
2699 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2700 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2701 we're just using it, not redefining it, we can use a K&R style
2703 (sleep): Declare this, too, if the system hasn't.
2704 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2705 scm_uthread_sleep if they're available; otherwise, just call the
2707 * scmconfig.h.in: Regenerated.
2709 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2711 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2713 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2715 * threads.c: Doc fix.
2717 The argument type of usleep varies from system to system,
2718 as does the return type. We really shouldn't be redefining usleep
2719 at all, but I don't have time to clean that up before the 1.3.
2720 release. It's on the schedule for afterwards. (Thanks to Julian
2722 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2724 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2725 * scmconfig.h: Regenerated.
2727 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2728 right way to handle system variation. Autoconf's approach is the
2730 * simpos.h (scm_software_type): Declaration deleted.
2732 * script.c (scm_find_executable): Don't test if unix is #defined
2733 here; first, NetBSD doesn't #define it, and second, it's the wrong
2734 way to go about these things. (Thanks to Perry Metzger.)
2735 (dld_find_executable): Delete this MSDOS support code. This isn't
2736 the way we want to support this; it needs to be rethunk at a
2739 * genio.c (scm_do_read_line): Don't just politely check that the
2740 line was either non-empty or EOF. Abort if it's empty and not
2743 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2745 * scmconfig.h.in: Regenerated.
2747 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2750 * genio.c (scm_do_read_line): Count lines correctly when the file
2751 doesn't end in a newline.
2753 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2755 * genio.c (scm_do_read_line): Maintain the line count correctly.
2756 (Thanks to Harvey J. Stein and Greg Harvey.)
2758 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2761 * numbers.c (big2str): Protect t from garbage collection until
2762 we're done. (Thanks to Gary Houston.)
2764 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2766 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2768 * Makefile.in: Regenerated.
2770 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2771 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2774 Do magic to mix reads and writes on stdio FILE-based ports.
2775 (Thanks to Christian Lynbech.)
2776 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2778 (pre_read, pre_write): New functions.
2779 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2780 local_fputs): Call them.
2781 (local_fflush): Mark the port as ready for reading and writing.
2782 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2783 flags on new port objects. This might not be accurate --- who
2784 knows what state the FILE * is in when we get it --- but it won't
2785 do extraneous calls to fflush or fseek, so it's no worse than the
2786 behavior before this change.
2787 * ports.h: Add comment.
2789 Centralize the creation of port objects based on stdio FILE * in
2790 fports.c; don't just throw them together anywhere.
2791 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2792 what the rest of Guile wants. Don't set the revealed count;
2793 that's only appropriate for stdin, stdout, stderr.
2794 (scm_standard_stream_to_port): This function does set the revealed
2796 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2797 not scm_stdio_to_port.
2798 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2799 * fports.c (scm_open_file): Same.
2800 * posix.c (scm_pipe): Same.
2801 * socket.c (scm_sock_fd_to_port): Same.
2802 * ioext.c (scm_fdopen): Same.
2803 (scm_freopen): Moved from here to...
2804 * fports.c (scm_freopen): ... here. This is really something that
2805 munges the internals of an fport, so it should go here.
2806 * fports.h (scm_stdio_to_port): Adjust prototype.
2807 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2808 * ioext.h (scm_freopen): Prototype removed.
2810 * filesys.c (set_element, get_element): This can work on both pipe
2811 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2814 * scmconfig.h.in: Regenerated.
2816 Change the definition of the functions in scm_ptobfuns so that
2817 they get passed the port object, not the port's stream.
2818 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2819 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2820 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2821 Pass the port itself to the scm_ptobs function.
2822 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2823 scm_generic_fgets): Same.
2824 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2825 getc_void_port, fgets_void_port, close_void_port): Just change the
2826 argument names; these functions don't really do anything.
2827 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2828 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2829 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2830 Also, use prototyped definitions, and get rid of the extra
2832 (scm_fptob, scm_pipob): We don't need casts here any more.
2833 * strports.c (prinstpt): Use prototype declarations.
2834 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2835 and use SCM_STREAM to get the string info. Also, use prototyped
2836 definitions, and get rid of the extra declarations.
2837 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2840 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2841 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2843 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2844 scm_fgets, for consistency.
2845 (scm_fptop, scm_pipob): References updated.
2847 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2849 Include the source location in error messages for scripts.
2850 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2851 stack is still there when we catch the error.
2852 * throw.c (handler_message): If we are handling an error with a
2853 message, then put together the proper arguments and call
2854 scm_display_error, instead of scm_display_error_message. That
2855 displays source location, if it can find it.
2857 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2859 * gc.c (scm_unprotect_object): Change this so that calls to
2860 scm_protect_object and scm_unprotect_object nest properly.
2861 (scm_protect_object): Doc fixes.
2863 * strings.c (scm_string_set_x): Require the argument to be a
2864 writable string, not a substring or a symbol.
2865 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2866 (Thanks to John Redford and Charbel Jacquin.)
2868 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2870 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2872 * eval.c (safe_setjmp): Remove this misunderstanding.
2873 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2876 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2878 * libguile.h: Mark these as C declarations, for compilation by C++
2881 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2882 __cplusplus clause. I seriously doubt this ever worked the way
2883 the author seems to have intended.
2885 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2887 Utterly needless cleanups to hopelessly messy code.
2888 * ports.c: Doc fixes.
2889 (scm_fflush): Moved to ...
2890 * genio.c (scm_fflush): ... here, amongst all the other port
2891 method invocation functions.
2892 * genio.h, ports.h: The prototype moves too.
2894 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2896 * backtrace.c (display_error_body): The current frame does not
2897 always have a parent frame; consider a function called directly
2898 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2901 * alloca.c (alloca): Undo yesterday's changes, and simply call
2902 malloc directly for storage, and abort if we don't get what we
2903 want. The situation is much simpler --- just call malloc. Emacs
2904 has bizarre/evil requirements (signal handlers might malloc unless
2905 you set this global flag, so you have to set the flag around all
2906 calls to malloc) which we are certainly not going to conform to,
2907 so we can do the simple and obvious thing.
2909 * coop.c (coop_condition_variable_wait): Make this function
2910 static. It's only useful internally --- you should never just
2911 wait on a condition variable.
2912 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2914 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2916 * unif.c (scm_array_set_x): Accept any kind of number as an
2917 element for a uniform vector of doubles. This is more consistent
2918 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2920 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2921 works; I can't conveniently test it myself. (Thanks to Dvid
2922 Tillman for the bug report.)
2924 * init.c: Doc fixes.
2926 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2927 from here, not from scm_compile_shell_switches (which is a pretty
2928 dumb place to do it).
2929 (scm_load_startup_files): New function.
2930 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2931 * script.c (scm_compile_shell_switches): Don't load the startup
2933 (scm_ice_9_already_loaded): Variable moved.
2934 * init.c (scm_load_startup_files): Prototype for new function.
2935 * gh_init.c (gh_enter): Doc fix.
2937 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2939 Some anti-warning changes from Greg Harvey.
2940 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2941 warnings when it doesn't understand our NORETURN declarations in
2943 * posix.c (scm_mknod): Similar.
2945 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2947 * posix.c (scm_getpwuid): If we can't find an entry, return our
2948 own message, instead of using scm_syserror --- the getpwMUMBLE
2949 functions don't set `errno' to anything interesting.
2951 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2953 Get rid of warnings from the cooperative threading system.
2954 * threads.h (scm_single_thread_p, scm_yield,
2955 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2956 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2957 scm_wait_condition_variable, scm_signal_condition_variable): Add
2958 prototypes for these Scheme-visible functions.
2959 * coop-defs.h (coop_next_runnable_thread,
2960 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2961 Prototypes for these here, even though they're from iselect.c.
2962 (coop_condition_variable_wait, coop_join): Add prototypes.
2963 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2964 scm_threads_free_condvar): Make these smob functions static.
2965 * coop-threads.h (coop_init): Give this a real prototype.
2966 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2967 (coop_next_runnable_thread): No need to provide prototype; it's in
2970 * scmconfig.h.in: .detarenegeR
2972 * iselect.c, threads.c: Doc fixes.
2974 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2976 * Makefile.in: Regenerated with a patched automake, to get
2977 dependency generation right when using EGCS.
2979 * inet_aton.c (inet_aton): Add prototype, to remove compiler
2980 warning. (Thanks to Robert Pluim.)
2982 * inet_aton.c (inet_aton): Reassure the compiler that the
2983 arguments to the <ctype.h> macros are all unsigned characters, not
2986 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2988 Getting rid of more warnings...
2989 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
2990 today's change to ../configure.in.
2991 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
2992 * scmconfig.h.in: Regenertaded.de.,.__
2993 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
2994 (scm_localtime, scm_mktime): Use a const char * to manipulate the
2997 * readline.c: Doc fix.
2998 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
2999 * readline.h (scm_filename_completion_function): Add prototype.
3000 (scm_init_readline): Make this into a prototype.
3002 * readline.c (scm_filename_completion_function): Use SCM_PROC to
3003 declare this, instead of calling scm_make_subr manually.
3005 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
3007 * readline.h (scm_init_readline): Add prototype for this.
3008 (scm_init_readline): Make this a real prototype.
3010 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
3012 Warning fixes from Maciej Stachowiak:
3013 * backtrace.h (scm_display_application, scm_backtrace): Add
3015 * debug.c (scm_m_start_stack): Make this function static.
3016 * fluids.h (scm_fluid_p): Add prototype.
3017 * procprop.c (scm_i_procedure_arity): Make this function static.
3018 * regex-posix.c (scm_regexp_error_msg): Make this function static.
3019 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
3020 * root.h (scm_dynamic_root): Add external prototype.
3021 * scmsigs.h (scm_usleep): Add external prototype.
3022 * script.h (scm_init_script): Use prototype, not K&R decl.
3023 * stacks.h (scm_stack_id): Add external prototype.
3024 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
3026 1998-09-30 Mark Galassi <rosalia@cygnus.com>
3028 * gh.h: took out the definitions of vset and vref, since they are
3029 replaced by the proper vector routines that correspond to the R4RS
3032 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
3034 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
3035 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
3036 third argument, a C expression that should result in a SCM value,
3037 which is used to initialize the variable. Reimplemented
3038 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
3041 * version.h (scm_libguile_config_stamp): Add prototype.
3042 (From Maciej Stachowiak.)
3044 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
3046 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
3047 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
3049 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
3051 * print.c (scm_iprin1): Rather than having one i, and using it in
3052 several places, declare a fresh i local to each block where it is
3053 used, and give it a signedness appropriate to its use in each case.
3054 (scm_iprlist): Same.
3056 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
3057 comparison warnings.
3059 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
3060 signed/unsigned clashes.
3062 * posix.h (scm_tmpnam): Added prototype.
3064 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
3065 scm_make_subclass_object): Add external prototypes.
3067 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
3068 comparison is okay here.
3070 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3072 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3073 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3075 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3078 * load.c (swap_port): Make this function static.
3080 * load.c (scm_search_path): Make max_path_len and max_ext_len
3081 unsigned, since they're compared against string sizes.
3083 * load.c (init_build_info): Make i unsigned.
3085 * ioext.h (scm_read_line): Add prototype.
3087 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3088 scm_hash_fn_remove_x): Make hash bucket index local variable k
3089 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3090 accurately as possible.
3092 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3093 comparisons, and range checking to make sure those casts are
3096 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3097 signed/unsigned comparisons.
3099 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3100 avoid signed/unsigned comparisons.
3101 * smob.h (scm_numsmob): Change extern declaration to match.
3103 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3104 avoid signed/unsigned comparisons.
3105 * ports.h (scm_numptob): Change extern declaration to match.
3106 (scm_current_load_port, scm_set_port_line_x,
3107 scm_set_port_column_x): New prototypes.
3109 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3110 test code, and it causes warnings.
3112 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3113 gh_uniform_vector_ref): Added prototypes.
3115 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3116 debugging support unconditionally. That's backtrace.c, stack.c,
3117 debug.c, and srcprop.c.
3118 (EXTRA_libguile_la_SOURCES): Omit those from here.
3119 * Makefile.in: Regenerated.
3121 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3123 * options.c (scm_options): Bugfix: Allow empty list of options!
3125 * debug.c, debug.h (scm_single_step): Removed.
3126 (scm_with_traps): New procedure. This procedure could easily be
3127 written in Scheme but needs to be highly optimized.
3129 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3131 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3132 Check SCM_TRAPS_P before trapping.
3134 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3136 Changes to avoid signed/unsigned comparison warnings.
3137 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3138 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3139 so they can have appropriate types for each application. Make i
3140 signed. Use initializers in some spots. I'll probably pay for
3142 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3143 (scm_must_realloc): Make nm unsigned.
3144 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3145 (scm_init_storage): Use prototype-style definition, and make the
3147 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3148 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3150 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3151 avoid signed/unsigned comparison warnings, and because the return
3152 value of readlink may be -1. Don't bother casting the third
3153 argument to readlink.
3155 * filesys.c (scm_dirname, scm_basename): Move these to their own
3156 page, at the end of the file.
3157 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3159 * eval.h (scm_eval_options_interface): Add external prototype for this.
3160 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3162 * eval.c (scm_lookupcar1): Make this static.
3164 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3165 Make these prototype declarations, not K&R-style.
3167 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3168 unsigned comparison warning.
3170 * appinit.c: File removed. It had a single function in it, empty,
3171 whose reason for existence is explained in no documentation or
3172 comment. I think it's there as a default for some Tcl-style
3173 initialization, but Tcl abandoned that approach a while ago.
3174 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3175 (BUILT_SOURCES): Remove appinit.x.
3176 * Makefile.in: Regenerated.
3178 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3180 * Makefile.in: Regenerated using the last public version of
3181 automake, not the hacked Cygnus version.
3183 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3185 Remove Totoro kludge.
3186 * Makefile.in, scmconfig.h.in: Regenerated.
3187 * init.c, readline.c: Don't check if TOTORO is #defined.
3189 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3191 * Makefile.am: Adjust for new thread configuration system.
3192 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3193 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3195 (THREAD_LIBS): Definition deleted; automake will generate such
3196 things automatically.
3197 * Makefile.in: Regenerated.
3199 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3201 Simplify smob and port marking; set the mark bit in the generic
3202 marking code, and make marker routines only responsible for
3203 turning up outgoing pointers.
3204 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3205 before calling the marking function. Don't call the marking
3206 function if it's zero.
3207 * markers.c (scm_mark0): Just return #f. This function isn't
3208 necessary at all now, but it's harmless to call it. We'll leave
3209 it in so other folks' code doesn't croak at link time.
3210 (scm_markcdr): Don't call SCM_SETGC8MARK.
3211 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3212 * dynl.c (mark_dynl_obj): Same.
3213 * root.c (mark_root): Same.
3214 * srcprop.c (marksrcprops): Same.
3215 * unif.c (markra): Same.
3216 * variable.c (scm_markvar): Same.
3217 * ports.c (scm_markstream): Same.
3218 (void_port_ptob): Specify zero for our marking function.
3219 * debug.c (debugobjsmob): Same.
3220 * dynwind.c (guardsmob): Same.
3221 * filesys.c (dir_smob): Same.
3222 * fluids.c (fluid_smob): Same.
3223 * fports.c (scm_fptob, scm_pipob): Same.
3224 * mallocs.c (mallocsmob): Same.
3225 * regex-posix.c (regex_t_smob): Same.
3226 * smob.c (freecell, flob, bigob): Same.
3227 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3228 * throw.c (jbsmob, lazy_catch_funs): Same.
3230 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3232 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3233 scm_copy_tree on code in order not to let memoized code to leak
3234 out. Thus, scm_copy_tree needs to copy vectors as well since
3235 quasiquote can introduce evaluated code also inside vector
3238 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3240 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3242 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3243 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3246 * unif.c: Say that ivect and uvect are of type signed and unsigned
3247 long instead of int in commentary so that it correctly describes
3250 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3252 * stime.c: Removed declaration of strptime. (It should be
3253 declared by the system headers. If it turns out that some systems
3254 don't, we'll handle that then.) (Thanks to Greg Troxel.)
3256 * stime.h: Renamed TIMEH --> STIMEH
3258 * backtrace.c (scm_display_error, scm_display_backtrace): In order
3259 to increase portability, don't use structure assignment.
3260 (Thanks to Nicolas Neuss.)
3262 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
3264 (finalize_fd_sets): Added empty statement after last case label.
3265 (Thanks to Nicolas Neuss.)
3267 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
3270 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
3272 * init.c, readline.c: OK, I won't have these readline.x bug
3273 reports anymore. We've had them since April. The current reason
3274 is a completely unintelligible failure of totoro.red-bean.com to
3275 do the test for rl_getc_function in libreadline correctly. This
3276 kludge overrides the test if we're on totoro so that the snapshot
3277 generation process can work.
3279 * readline.c: Define a strdup replacement if not existent on system.
3281 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3283 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
3284 This change makes scm_make_vector R5RS compatible. We cannot keep
3285 the third argument since people want to be able to deduce the form
3286 of the C function call only by looking at R5RS. (At the same time
3287 we have removed some unnecessary complexity!)
3289 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
3290 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
3291 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
3292 argument in call to scm_make_vector.
3294 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3296 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
3297 This macro is useful in applications.
3299 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3301 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
3302 (scm_parse_path, scm_search_path): New Scheme level procedures.
3304 * load.h (scm_internal_parse_path, scm_parse_path,
3305 scm_search_path): Declared.
3307 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3309 * filesys.c (dirname, basename): New procedures.
3311 * init.c (scm_boot_guile_1): Removed condition around
3314 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
3315 new data type (guards) for representation of C level guards and
3316 data on the wind chain.
3317 (scm_internal_dynamic_wind): New function.
3319 * dynwind.h: Declare scm_internal_dynamic_wind.
3321 * root.h (scm_root_state): Added scm_cur_loadp.
3323 * root.c (mark_root): Added comment about cur_loadp.
3325 * load.c: #include "dynwind.h";
3326 (scm_primitive_load): Use scm_inner_dynamic_wind to update
3329 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
3331 * ports.c (current-load-port): New procedure.
3333 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3335 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
3336 not a tty, return #f.
3338 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
3339 to Julian Satchell and Roland Kaufmann.)
3341 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
3342 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
3344 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3346 * debug.h, debug.c (scm_start_stack): New function. Implements
3347 the guts of old scm_m_start_stack.
3349 * debug.c (scm_m_start_stack): Use scm_start_stack.
3351 * init.c (scm_start_stack, scm_restart_stack): Renamed to
3352 start_stack and restart_stack. (These have static scope.)
3354 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3356 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
3357 readline functions to come in release 2.3. (Thanks to Chet
3359 (handle_errors): Use the above functions.
3361 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3363 * readline.c: Improvements for readline support: Handle errors
3364 better; Implement before-read-hook.
3366 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3368 * init.c (scm_boot_guile_1), readline.c: Test for
3369 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3370 assure that we have version >= 2.1.)
3372 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3374 * readline.c (scm_readline): Defer interrupts while we're calling
3377 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3378 away the string to add_history.
3379 (completion_function): Do completion for readline. (Thanks to
3381 (scm_filename_completion_function): New procedure: Filename
3383 (current_input_getc): New function. Use this one instead of
3384 standard getc from readline.
3386 * throw.c, throw.h (scm_handle_by_throw): New function: This
3387 handler throws errors to next handler on the dynwind chain.
3389 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3391 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3394 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3396 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3398 (scm_procedure_properties): Modified to return arity together with
3400 (scm_procedure_property): Added the read-only property `arity'.
3401 (scm_set_procedure_property_x): It is an error to set the `arity'
3404 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3405 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3407 * procprop.h (scm_sym_arity): New symbol.
3409 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3410 to set the dispatch procedure of an operator or entity object.
3412 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3413 Made procedure slots read-only.
3415 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3416 scm_tcs_cons_gloc case in zero args switch; Fixed args
3417 construction for operators in scm_tcs_cons_gloc case in two args
3420 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3422 * fluids.c: Removed use of assert.h (in order to avoid
3425 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3427 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3429 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3430 change makes the evaluator safer at the cost of evaluation speed.
3431 It handles the case when the user has added a non-immediate
3432 improper end of the application form, e.g., `(+ 0 . x)'.
3433 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3434 minimize the extra cost as much as possible. The new code is
3435 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3436 problem with structs planted directly in the code (e.g. by a
3437 macro). This no longer causes segmentation fault. (Thanks to
3440 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3441 arg `proc' in order to be able to throw errors; New argument
3444 * Removed extra #include "debug.h"
3446 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3448 * scmsigs.c: Declare usleep as returning void on some systems.
3449 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3452 * coop.c (usleep): Return void on some systems.
3454 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3456 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3458 * coop.c: Changed return type of usleep to int.
3460 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3461 isn't found in the OS.
3463 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3464 isn't enabled. (Thought that I had made this change ages ago...)
3466 * iselect.c: Declare bzero if not defined by OS.
3468 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3470 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3471 condition. (Thanks to John Tobey.)
3473 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3474 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3477 * __scm.h: Start the long-term project of moving to POSIX threads.
3478 Phase 1: Classification of all critical sections.
3479 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3480 for A sections. (See comments in __scm.h for details.)
3482 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3483 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3485 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3487 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3488 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3489 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3490 dependencies on $(srcdir)/Makefile.in
3491 $(top_builddir)/config.status in order to avoid circularity.
3493 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3494 from argc if argc was 0 initially.
3496 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3497 in generation of libpath.h.
3499 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3501 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3502 libguile from 2 to 3.
3504 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3506 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3508 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3510 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3511 scm_set_port_column_x, scm_port_filename,
3512 scm_set_port_filename_x): Removed optional arguments. Added
3513 proper argument checking.
3515 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3516 stack size in machine words.
3518 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3519 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3520 to Ole Myren Röhne.)
3522 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3524 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3525 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3527 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3530 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3531 procedure apply: Copy argument lists before pushing them unto the
3532 environment so that the environment won't get mutated due to
3533 manipulation of procedure arguments. This should perhaps be
3534 regarded as a temporary solution until someone finds a more
3535 efficient one. (Thanks to Maciej Stachowiak.)
3537 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3539 * script.c (scm_compile_shell_switches): Use "guile" as default
3540 zero arg if argc is NULL.
3542 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3544 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3545 is zero. (Thanks to Dirk Herrmann.)
3547 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3549 * ports.c (scm_add_to_port_table): First line is now line 0
3550 (was 1). (Interface changed according to suggestion by Per
3553 * backtrace.c (display_header): Add 1 to line and column numbers
3554 when presenting them to the user.
3556 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3557 from debug.c --> eval.c
3559 * eval.h, eval.c (scm_eval_options_interface): New options
3561 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3562 i.e. stacks for new threads.
3564 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3566 * eval.c (unsafe_setjmp): Removed with #if 0.
3568 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3571 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3572 to avoid compiler warnings.
3574 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3576 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3578 * throw.c (handler_message): Print message on current error port
3579 instead of default error port. (Thanks to Maciej Stachowiak.)
3581 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3583 * ports.c (scm_add_to_port_table): allocate in units of
3584 struct scm_port_table *, not struct scm_port_table.
3585 * posix.c (scm_close_pipe): remove the port from the port table
3587 Thanks to Rob Engle for both fixes.
3589 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3591 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3592 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3594 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3596 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3598 * backtrace.c (display_error_body, display_backtrace_body),
3599 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3600 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3601 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3602 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3605 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3606 don't receive the jmpbuf arg anylonger.
3607 (scm_catch): Don't accept a #f tag.
3608 (scm_throw): Check that key is a symbol.
3609 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3611 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3613 * async.c (async_pending): Removed declaration.
3615 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3617 * dynwind.c (scm_wind_chain): New debug function.
3619 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3620 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3621 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3622 extra layer of functions around the body and handler of a thread.
3623 This extra layer makes sure that the handler is called in the
3624 dynamic context of the surround (= empty dynwind list), but under
3625 the *dynamic root* of the body. We can not use the dynamic root
3626 of the surround since that root belongs to another thread => stack
3627 is not handled correctly. It may seem ugly to use this extra
3628 layer, but the extra cost in terms of execution time is really
3629 negligible compared to the total amount of time required to create
3630 a thread, and it would reduce maintainability to duplicate the
3631 crucial and complicated steps performed by cwdr.
3633 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3634 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3635 get re-enabled. The important effect of this is that interrupts
3636 are blocked during thread switching so that thread data structures
3637 don't risk getting messed up by an unfortunate signal.
3638 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3639 seems to do more aggressive optimization which actually move
3640 instructions around in these macros in a fatal way. Therefore:
3641 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3642 just superstitious...)
3643 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3644 This macro should be used instead of SCM_ASYNC_TICK since the
3645 latter doesn't do context switches any more.
3647 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3648 instead of SCM_ASYNC_TICK.
3650 * coop.c, iselect.c: Since thread switches are now performed with
3651 interrupts masked, we can't use the old mechanism of delivering
3652 signals immediately when they arrive. Signals must instead be
3653 delivered when the asyncs run *after* the end of the critical
3654 section in scm_internal_select. But this also means after context
3655 switch so that the signal will be delivered to a different thread.
3656 To avoid this, I have changed the protocol of
3657 coop_wait_for_runnable_thread and friends so that they are allowed
3658 to return the original thread. So, if a signal arrives during
3659 scm_internal_select, we won't any longer be forced do a context
3660 switch, but can remain in the same thread and deliver the signal
3663 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3664 scm_asyncs_pending and made it global.
3666 * iselect.c: Small fixes.
3668 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3669 coop_condition_variable_init, coop_condition_variable_wait,
3670 coop_condition_variable_signal): Changed return type from `void'
3671 to `int'. This is to adhere closer to the pthreads interface.
3672 This, in turn, is part of an attempt to provide C versions of the
3673 mutex and condition variable primitives which can be part of a
3674 frontend to COOP or pthreads.
3676 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3677 coop_condition_variable_destroy): New functions.
3679 * coop-threads.c (scm_wait_condition_variable): Use
3680 coop_condition_variable_wait_mutex.
3682 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3683 Definitions moved to coop-defs.h.
3685 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3686 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3687 scm_cond_destroy): New C interface to mutecis and cond vars.
3689 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3691 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3693 * iselect.c: Now several threads can wait on the same file
3694 descriptor. The behaviour is compatible with OS select: All
3695 threads waiting for the fd return with the same status.
3697 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3699 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3700 Can spawn a thread from application C code.
3702 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3704 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3705 gh_doubles2scm): New functions.
3707 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3709 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3710 commented-out version of gh_eval_str()
3712 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3714 * socket.c (scm_bind): free soka after use.
3716 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3718 * stime.c (tzvar): new variable.
3719 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3720 avoid memory leaks when allocating.
3722 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3724 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3727 * gc.c, tags.h: Doc fixes.
3729 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3731 * eval.c (macro-eval!): Removed. This function was a design bug.
3732 It allowed memoized code to leak out to the scheme level. Most
3733 things that you could do with `macro-eval!' can be done with
3736 1997-12-20 Tim Pierce <twp@skepsis.com>
3738 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3739 scm_fgets now depends on ftell(3) to know how many bytes were
3742 1997-12-15 Tim Pierce <twp@skepsis.com>
3744 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3745 dealing with strings.
3747 1997-12-13 Tim Pierce <twp@skepsis.com>
3749 Make %read-line more suitable for implementing read-line efficiently.
3750 * ioext.c (scm_read_line): Strip the terminating newline from a
3751 string, and return a cons of the string and its terminator.
3753 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3754 of the string that is read is stored in this memory location.
3755 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3756 * genio.c, genio.h (scm_do_read_line): Update caller.
3757 * ports.h (scm_ptobfuns): Update typedef.
3758 * fports.c (scm_fptob, scm_pipob): Update struct.
3760 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3762 * filesys.c (set_element): Return file descriptor.
3763 (fill_select_type): Return the highest file descriptor.
3764 (scm_select): Tell select about the highest file descriptor. On
3765 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3766 Therefore the extra overhead for calculating the maximum fd seems
3767 to be more than compensated. Is this correct? In any case,
3768 scm_internal_select will be much faster with this info.
3769 (scm_select, fill_select_type, set_element): Don't accept any kind
3770 of object in the file descriptor list or vector.
3772 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3774 * iselect.c (finalize_fd_sets): Bugfix.
3776 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3778 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3779 when using scm_internal_select (since we might switch to another
3782 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3784 * simpos.c (scm_system): always define: use sysmissing if not
3785 available. Check for HAVE_SYSTEM instead of _Windows (does
3786 Windows lack system or does it have an unusable one?).
3787 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3788 Let the argument be optional: if not supplied, call system(NULL).
3790 * ports.c (scm_close_port): relax the type check from OPPORTP to
3791 PORTP; closing a closed port is allowed.
3793 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3795 * fports.c (scm_fgets): Return if the last char in a chunk is
3796 newline. When fgets returns a string whose length is `size-1', it
3797 is ambiguous whether a whole line was retrieved, so we must check
3798 explicitly whether a line terminator is present.
3800 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3802 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3803 before taking the CDR. (Thanks to Harald Meland.)
3805 * filesys.c (scm_stat): Slightly optimized.
3807 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3809 * ports.c (scm_close_port): Make sure the port is open before
3812 * guile-snarf.in: Pass args through to gcc in a way that preserves
3813 whitespace boundaries. (Thanks to Greg Badros.)
3815 1997-12-02 Tim Pierce <twp@skepsis.com>
3817 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3818 statement. (Thanks to Doug Evans for pointing this out.)
3820 1997-12-01 Tim Pierce <twp@skepsis.com>
3822 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3824 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3826 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3827 errno macro expansion of this field name. (errno is a C
3828 preprocessor macro on some systems.)
3830 1997-11-29 Tim Pierce <twp@skepsis.com>
3832 * iselect.c: Doc fix.
3834 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3836 * init.c (scm_start_stack): Removed initialization of
3837 scm_the_last_stack_var.
3839 * backtrace.h: Declare scm_the_last_stack_var.
3841 * backtrace.c: Define scm_the_last_stack_var.
3843 * root.c (mark_root): Don't mark the_last_stack_var.
3845 * root.h (scm_root_state): Removed the_last_stack_var.
3847 * throw.c: Added #include "fluids.h"
3848 (ss_handler): `the-last-stack' is now a fluid.
3850 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3851 --> the_last_stack_fluid.
3853 * backtrace.c: Added #include "fluids.h"
3854 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3855 (scm_backtrace): `the-last-stack' is now a fluid.
3857 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3858 after scm_init_fluids.
3860 1997-11-28 Tim Pierce <twp@skepsis.com>
3862 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3864 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3865 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3867 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3869 * iselect.c (coop_next_runnable_thread,
3870 coop_wait_for_runnable_thread): Disable interrupts so that no
3871 async is executed before a potential error_revive.
3872 (scm_internal_select): Disable interrupts during the parts of the
3873 code which manipulate the sleep queue and the file descriptors.
3875 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3877 * Makefile.am: Added iselect.c and iselect.h.
3879 * coop.c (coop_qinit): Initialize fields used by
3880 scm_internal_select.
3881 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3882 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3883 replacement in iselect.c.
3884 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3885 coop_join): If GUILE_ISELECT enabled, use
3886 coop_wait_for_runnable_thread instead of
3887 coop_next_runnable_thread.
3888 (usleep, sleep): New replacements for system functions if
3889 GUILE_ISELECT is enabled.
3891 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3893 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3895 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3896 iselect.h. Implement Scheme level `select' using
3897 scm_internal_select. (See NEWS.)
3899 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3901 * init.c: Call scm_init_iselect.
3903 * iselect.h, iselect.c: New files. Implements
3904 scm_internal_select. (See NEWS.)
3906 1997-11-27 Tim Pierce <twp@skepsis.com>
3908 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3909 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3910 and scm_must_free, since ultimately the string returned will be copied
3911 by scm_makfrom0str anyway. Also, read any characters that may have
3912 been pushed onto the port with scm_ungetc.
3913 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3914 * ioext.c (scm_read_line): Free string after Guilifying it.
3915 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
3917 1997-11-26 Anthony Green <green@hoser.cygnus.com>
3919 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
3921 * gh.h: Safely wrap prototypes for c++ usage.
3923 1997-11-25 Mark Galassi <rosalia@cygnus.com>
3925 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3926 gh_repl (argc, argv).
3928 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3930 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3931 and to invoke scm_shell().
3932 (gh_launch_pad): took out the loading of boot-9.scm from here,
3933 since it is probably best to let the user control that. In fact,
3934 gh_repl() now invokes scm_shell() which does that.
3936 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3938 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3941 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
3943 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
3944 yesterday's underscore patch. (Thanks to Marius Vollmer for
3947 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
3949 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
3950 DLSYM_ADDS_USCORE is not defined.
3952 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
3954 * gh_data.c (gh_uniform_vector_length):
3955 (gh_uniform_vector_ref): started implementing the uniform types in
3958 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
3960 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3961 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3963 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3965 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
3966 configure.in was changed).
3968 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
3970 * Makefile.am (modinclude_HEADERS): Include readline.h here.
3971 * Makefile.in: Regenerated.
3973 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
3975 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
3976 OPORT is an `open' port, not an output port.
3978 * filesys.c (scm_close, set_element, get_element, scm_chown,
3979 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
3980 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
3981 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
3982 scm_close_port, scm_port_line, scm_set_port_line_x,
3983 scm_port_column, scm_set_port_column_x, scm_port_filename,
3984 scm_set_port_filename_x, scm_port_mode,
3985 scm_close_all_ports_except, scm_set_current_output_port,
3986 scm_set_current_error_port): Likewise
3987 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
3988 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
3990 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
3991 * backtrace.c (display_backtrace_body): Likewise
3992 * fports (scm_setvbuf): Likewise
3993 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
3994 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
3995 scm_getpeername, scm_send, scm_sendto): Likewise
3996 * unif.c (scm_uniform_array_write): Likewise
3998 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
4000 Minor problems with substring-related tag changes.
4001 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
4002 exactly what we want to leave in to detect substrings.
4003 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
4004 * tags.h: Fix diagrams and comments describing the S tag bit;
4005 remove vestigial remarks about the D tag bit.
4006 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
4007 * strings.c: Formatting tweaks.
4009 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
4010 variable first; then SCHEME_LOAD_PATH, with a warning message.
4011 (scm_parse_path): New function.
4012 * script.c: Doc fixes.
4014 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
4016 Readline support, from Daniel Risacher.
4017 * readline.c, readline.h: New files.
4018 * init.c: #include "readline.h".
4019 (scm_boot_guile_1): Call scm_init_readline, if we have it.
4020 * Makefile.am (libguile_la_SOURCES): Include readline.c.
4021 * Makefile.in: Regenerated.
4022 * scmconfig.h.in: Regenerated, after change to ../configure.
4024 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4026 * gh.h: gh_vector_set -> gh_vector_set_x
4028 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4030 * gh_data.c (gh_vector_set_x): changed name to make it consistent
4031 with the ! -> _x mapping when going from Scheme to C.
4033 1997-10-19 Mark Galassi <rosalia@cygnus.com>
4035 * gh.h (gh_reverse):
4043 (gh_assoc): added these gh_ functions implemented as macros.
4045 * gh_predicates.c (gh_null_p):
4046 (gh_string_equal_p): added these two missing predicates.
4048 * gh_list.c (gh_append):
4053 (gh_set_cdr_x): added these routines as I go through and try to
4054 complete the picture R4RS functions that should be mirrored in the
4057 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4059 * tags.h (scm_tc7_substring): Changed the comment and code to
4060 conform with the changes below. Folks! We have suddenly two new
4061 free tc7 codes!!! Jummy, jummy!
4063 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
4065 * Makefile.in: Rebuilt.

4080 * gc.c (scm_gc_mark): Don't handle mbstrings.
4081 (scm_gc_sweep): Likewise.
4082 * eval.c (SCM_CEVAL): Don't handle mbstrings.

4085 (SCM_TYP7D): Removed.
4086 (scm_tc7_mb_string): Removed.
4087 (scm_tc7_mb_substring): Removed.

4090 Don't include "mbstrings.h".
4091 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
4092 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
4094 Don't include "mbstrings.h".
4095 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
4096 (SCM_SYMBOL_SLOTS): Define as 4.
4097 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
4098 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
4099 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
4100 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
4101 struct.c, threads.c, throw.c, unif.c, variable.c: Use new

4118 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
4119 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
4121 1997-10-12 Mark Galassi <rosalia@cygnus.com>
4123 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
4125 * gh_test_c.c (c_vector_test): some improvements on the vector
4128 * gh.h (gh_vector): this used to exist but do the wrong thing.
4129 Now it (almost) does the right thing, though it takes a list
4130 instead of the individual arguments. I need to see how it could
4132 (gh_list_to_vector): added this function as a macro. Corresponds
4133 to Scheme's (list->vector ...).
4134 (gh_vector_to_list): added this function as a macro. Corresponds
4135 to Scheme's (vector->list ...).
4137 * gh_data.c (gh_vector_ref): renamed from gh_vref to
4138 gh_vector_ref, so that it resembles the Scheme routines more.
4139 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
4140 resembles the Scheme routines more.
4141 (gh_make_vector): this used to be (stupidly) called gh_vector().
4142 This is the right name, since it does the same thing as the Scheme
4143 (make-vector ...) procedure.
4145 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
4147 * ports.h: #include "libguile/print.h"
4149 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
4150 Some indentation fixes.
4152 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
4153 longer a user field; New field: class_flags.
4155 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
4157 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
4159 * gh_data.c (gh_bool2scm): new function which replaces
4160 gh_int2scmb(), which is now tagged as obsolete.
4162 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
4164 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
4165 macros should by convention not test for NIMPness.)
4166 (SCM_COERCE_OPORT): Adjust indentation.
4168 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
4169 SCM_NIMP test before SCM_PRINT_STATE_P.
4171 * struct.c, struct.h, gc.c: Renamed:
4172 scm_struct_i_layout --> scm_vtable_index_layout
4173 scm_struct_i_vcell --> scm_vtable_index_vcell
4174 scm_struct_i_vtable --> scm_vtable_index_vtable
4175 scm_struct_i_printer --> scm_vtable_index_printer
4176 scm_struct_i_vtable_offset --> scm_vtable_offset_user
4178 * struct.c (scm_print_struct): Use new printer slot; Default
4179 printing: Also output hex code of vtable so that type identity
4180 will be indicated as well.
4181 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
4182 Removed struct_printer_var; Removed struct-vtable-offset;
4183 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
4184 vtable-offset-user): New constants.
4186 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
4187 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
4188 If this slot contains a procedure, use that to print structures of
4189 the type represented by this vtable.
4191 * print.c (scm_iprin1): Don't print arguments of macro
4192 transformers. (They are always: exp env.); Bugfix: Unmemoize
4193 transformer source with correct environment.
4195 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
4197 Streamlining of call-with-dynamic-root:
4199 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
4200 there is now only one catch.
4201 (cwdr_outer_body): Removed.
4202 (cwdr_handler): New function.
4203 (scm_internal_cwdr): New function to perform the function of cwdr
4204 but take args that are more useful to C code. Also, the handler
4205 is now invoked *outside* of the new dynamic root, like the docs
4206 say. We no longer have to catch absolutely all errors, the caller
4207 is responsible for using a handler that does not throw, if he
4209 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4210 * root.h (scm_internal_cwdr): New prototype.
4212 Even more but risky streamlining:
4214 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4215 allocation of the jumpbuf of a root continuation. The changes
4216 below are controlled by it. They are now deactivated.
4217 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4218 the JMPBUF of the scm_rootcont to NULL before returning.
4220 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4221 when they are non-NULL.
4222 (scm_gc_mark): Likewise, mark only when non-NULL.
4224 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
4225 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
4227 * gc.c (scm_done_malloc): New function.
4228 gc.h (scm_done_malloc): New prototype.
4230 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
4231 (struct scm_print_state) [revealed]: New field.

4233 type checking purposes.
4234 (scm_valid_oport_value_p): New prototype.
4236 * print.c (scm_valid_oport_value_p): New function to check whether
4237 a certain value is acceptable as a port argument.
4238 (scm_print_state_vtable): New variable.
4239 (scm_free_print_state): Set `revealed' field to false.
4240 (scm_iprin1): Call user supplied closure printer with
4241 scm_printer_apply. Print in the traditional way when there isn't
4242 one or when it returns #f.
4243 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4244 Accept a port/print-state pair in addition to just a port.
4245 (scm_prin1): Don't return the print_state to the pool when it has
4247 (scm_printer_apply): Set `revealed' field of print_state to true.
4248 (scm_init_print): Set scm_print_state_vtable.
4249 (print_state_fluid, print_state_fluid_num): Removed.
4251 * throw.h (scm_handle_by_proc_catching_all): New prototype
4252 throw.c (scm_handle_by_proc_catching_all): New function
4254 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
4256 * Makefile.in: Regenerated with automake 1.2c.
4258 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
4260 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
4261 was looping endlessly.
4263 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
4265 * strports.c (scm_eval_string): Don't close the port.
4267 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
4268 former returns a nice normal integer. (Thanks to Daniel
4271 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
4273 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
4274 makefile variable as a build parameter called LIBS. The
4275 build-guile program will use this, for the time being.
4276 * Makefile.in: Regenerated.
4278 Thanks to Shiro Kawai:
4279 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
4280 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
4283 * Makefile.in: Regenerated with automake 1.2a.
4285 * script.c (scm_compile_shell_switches): If we hit the -c or --
4286 arguments, don't set the car of (command-line) to scm_usage_name,
4287 the prettified name of the guile executable; give it the full
4288 path, the way shells usually handle $0.
4290 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4292 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
4293 Scheme-level name `array-map' and renamed `serial-array-map' to
4294 `serial-array-map!'.
4296 * backtrace.c: Introduced exception handlers which now enclose
4297 `display-error' and `display-backtrace' so that error reporting
4298 won't get into infinite loops if an error occurs during displaying
4299 of the error. This can very easily happen with user supplied
4300 print call-back routines.
4302 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4304 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
4305 the names `serial-array-map' and `array-map' should be removed.)
4307 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
4309 * init.c (scm_boot_guile_1): Added scm_init_objects ().
4310 Added #include "objects.h"
4312 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
4313 Add #include "feature.h".
4315 * Makefile.am (libguile_la_SOURCES): Added objects.c.
4316 (modinclude_HEADERS): Added objects.h.
4318 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
4319 This test is needed at many places in the code and should be
4320 abstracted. (Motivated by the need of this test in libguiletk.)
4322 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
4323 (scm_eval_string), load.c (scm_primitive_load,
4324 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
4325 Use SCM_EOF_OBJECT_P.
4327 * eval.c (scm_init_eval): Add feature `delay'.
4329 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4331 * scmhob.h: Removed.
4333 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4335 * list.h (SCM_LISTn): New macros. Make list creation in C code
4336 prettier. The idea comes from STk.
4338 * sequences.h, sequences.c, append.h, append.c: Removed. These
4339 files implemented non-R4RS operations which would encourage
4340 non-portable programming style and less easy-to-read code.
4342 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
4345 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
4346 sequences.h, #include append.h.
4348 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
4351 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
4353 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
4355 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
4357 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4359 * eval.c: Added #include "objects.h"
4361 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
4364 * smob.c (scm_smob_prehistory): Create two objectsmobs with
4365 adjacent smob numbers.
4367 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4369 * procprop.h: Added declaration of scm_i_inner_name.
4371 * gsubr.c: New global symbol scm_i_inner_name.
4373 * debug.c (scm_procedure_name): Try procedure property
4374 `inner-name' if `name' fails.
4376 * print.c (scm_iprin1): Use scm_macro_name.
4378 * eval.c (scm_m_define): Give names to macros as well; Only the
4379 first top-level definition gives a procedure/macro a name.
4380 Otherwise confusing names can turn up in backtraces.
4381 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4382 `name'; Give names to macros as well.
4384 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4385 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4388 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4390 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4392 (prinmacro): Removed. The code has been moved/merged into print.c
4393 in order to decrease code redundancy. We want macros to print in
4394 a way equivalent to procedures, and it would be silly to duplicate
4395 the required code. (We don't want to maintain two places.)
4396 (macrosmob): Print field is now a NULL pointer.
4398 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4399 scm_macro_transformer): New prototypes.
4400 (scm_tc16_macro): Declared.
4402 * print.c (scm_iprin1): Added code for printing of macros. Macros
4403 are now printed in a way equivalent to procedures.
4405 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4407 * procs.h (scm_closure_p): Added declaration.
4409 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4411 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4412 Shouldn't pass "heap" as the subr name.
4414 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4416 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4417 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4418 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4419 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4420 SCM_BOOL_T. Any non-false value is true.
4422 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4424 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4425 scm_gensym): Added prototypes.
4427 * symbols.c (scm_gensym): New function. This will speed up
4428 certain types of applications (such as macro systems) which
4429 generate lots of symbols.
4431 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4433 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4435 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4437 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4438 specifier, since (2) or (2 . 3) would cause SEGV.
4439 (scm_transpose_array): more argument checking fixes.
4441 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4443 * Makefile.in: Regenerated.
4445 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4447 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4449 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4451 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4453 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4455 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4456 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4459 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4460 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4461 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
4462 scm_array_p, scm_array_rank, scm_array_dimensions,
4463 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
4464 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
4465 scm_array_prototype): Added case scm_tc7_wvect.
4467 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
4469 * errno.h: prototype for scm_strerror.
4470 * error.c (scm_strerror): new procedure.
4472 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4474 * list.c (scm_list_append_x): Allow non-pair as last argument.
4475 This is consistent with the R4RS append and is probably the
4476 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4478 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4480 * stime.h: prototype for scm_times.
4481 * stime.c (scm_times): new procedure.
4482 * ioext.c (scm_fseek): if the first argument is a file descriptor
4484 (scm_ftell): if the first argument is a file descriptor call lseek
4486 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
4487 * filesys.c (scm_chmod): if the first argument is a file descriptor,
4489 (scm_chown): if the first argument is a port or file descriptor,
4491 (scm_truncate_file): new procedure.
4492 Add DEFER/ALLOW INTS to a few other procedures.
4493 (scm_fsync): new procedure.
4494 (scm_open_fdes): new procedure.
4495 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
4497 (scm_fcntl): the first argument can now be a file descriptor. The
4498 third argument is now optional.
4500 * posix.c (scm_execl, scm_execlp): make the filename argument
4501 compulsory, since omitting it causes SEGV.
4502 (scm_sync): return unspecified instead of #f.
4503 (scm_execle): new procedure.
4504 (environ_list_to_c): new procedure.
4505 (scm_environ): use environ_list_to_c. disable interrupts.
4506 (scm_convert_exec_args): take pos and subr arguments and
4507 improve error checking.
4509 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4511 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4512 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4513 argument to SCM_ASSERT. Furthermore, the name of the function
4514 should be passed as first argument when signalling
4515 SCM_WNA. (Thanks to Thomas Morgan)
4517 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4518 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4519 dispatches on the number of actual args has a default case
4520 reporting an internal error. This is a vestige from a version
4521 that mallocated a SCM vector to hold the arguments. In the
4522 current version this check is too late: if it ever happens we will
4523 have already overstepped the bounds of the array.
4525 Also, the patch [...] adds a check for too many actual arguments."
4527 mdj: Removed check for "internal programming error".
4529 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4531 * gh_io.c (gh_write): New function.

4546 fold in the functionality of scm_primitive_dup.
4547 (scm_primitive_dup): deleted.
4549 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>

4589 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
4590 SCM_ASSERT: arg comes before pos.
4592 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4594 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
4595 to a list of length zero correctly.
4597 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

4615 * ioext.c (scm_primitive_dup2): return the new file descriptor
4616 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
4618 (scm_fdopen): bug fix: don't try to make port unbuffered until its
4619 stream has been set.
4620 (scm_duplicate_port): deleted, there's now an implementation in
4622 (scm_primitive_dup2): do nothing if newfd == oldfd.
4624 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
4626 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

4646 * filesys.h: scm_close prototype.
4647 * filesys.c (scm_close): new procedure, can close file descriptors
4648 and ports (scsh compatible).

4673 data. (dynl_smob): Use it.
4674 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4675 the dynamic object data below the linking of the object to avoid
4676 memory leak when the linking code throws an error. Now the code
4677 leaks a whole dynamically linked library when must_malloc throws,
4678 but that should be much less likely.

4682 Changes to compile under gnu-win32, from Marcus Daniels:

4698 (scm_setpwent): For setpwent.
4699 (scm_setegid): For setegid.

4720 think this is left over from the (eq? '() #f) days.
4722 * read.c (recsexpr): Give this a dummy definition if
4723 DEBUG_EXTENSIONS isn't #defined.
4725 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>

4738 alloca.lo will be included in @LIBLOBJS@. Something better than
4739 this should be possible.
4740 * Makefile.in: Regenerated.
4742 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4744 * simpos.h: prototype for scm_primitive_exit.
4745 * simpos.c (scm_primitive_exit): new procedure, terminates the

4751 argument and logior its components together, so the user doesn't
4752 have to do this explicitly. Also, if regexp/basic is supplied, then
4753 turn off REG_EXTENDED.
4754 (scm_init_regex_posix): New regexp/basic symbol.
4755 (REG_BASIC): #define this if it is not already present.

4774 flag; I don't think we support it.
4775 (scm_make_regexp): Make sure the user doesn't pass the
4778 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
4780 (scm_init_regex_posix): Define constants for the REG_mumble flags;

4792 (init_build_info): New function.

4798 * root.c: Establish a reliable catch-all handler for the new root.
4799 After all the Scheme handler function might signal an error too,
4800 and we don't want to lose that.
4801 (cwdr_inner_body): Renamed from cwdr_body.
4802 (cwdr_outer_body): New function, to establish the user's handler,
4803 and pass control to cwdr_inner_body.
4804 (cwdr): Establish the reliable catch-all handler here, and pass
4805 control to cwdr_outer_body.
4806 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
4807 the user's handler through to cwdr_outer_body.

4814 across this. Only works on GCC. Otherwise, we hope for the best.
4815 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4816 the feeling that real thread systems will not need this...
4818 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4820 Try to detect when people are using one version of libguile and a

4832 primitive definitions under their Scheme names.
4834 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4835 1:2. Helps avoid confusion between installed and uninstalled libs.
4837 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
4840 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
4841 backslash from definition; this should be used like: GDB_INTERFACE;
4843 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4845 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
4846 new port unbuffered until its stream has been set.
4848 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
4850 * ports.h: new prototype.

4860 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4862 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
4863 argument plain char *.

4866 * tag.c (scm_tag): Remove unreachable statement.
4867 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4868 top of the word, it should be unsigned.
4870 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4871 is defined, to avoid warnings; it's only used in the
4872 conflict-checking code. Which might go away anyway.
4873 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4874 conditionals; put the label definition in an #if too, to stifle
4877 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4878 ChangeLog-threads in the distribution.
4879 * Makefile.in: Regenerated.

4884 whitespace between lexical tokens (which munges the `%%%' snarf
4887 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4889 * load.c (scm_init_load_path): Append $(datadir)/guile to
4890 %load-path, so modules do not have to be installed in Guile's
4891 current version directory.
4893 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
4895 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
4896 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
4897 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
4898 call the sysdep functions with deferred ints.

4900 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
4901 deferred interrupts and insert SCM_ALLOW_INTS before throwing an

4919 condition during lookup (when using threads).
4920 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4921 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4924 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4926 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4927 supplied. (Change from Tim Pierce.)
4929 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4931 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4932 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4933 default and not `()'. `#f' is the canonical non-value in Scheme,
4936 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4938 * struct.c (struct_printer): New variable that holds a handle on
4939 the Scheme variable *struct-printer*. This variable can be set by
4940 Scheme code to override the printing of structures.
4941 (scm_print_struct): If struct_printer is set, call it. If it is
4942 not set, or returns #f, print the structure in the old fashion.
4943 Include "eval.h" for scm_apply.
4945 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4947 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4948 scm_struct_i_n_words to get the number of fields, not
4949 -scm_struct_n_extra_words.
4951 On the route to fancier struct printing:
4952 * struct.c (scm_print_struct): New function to print a structure.
4953 Include "genio.h" to support it. This function doesn't do
4954 anything interesting right now, but I think it should be here
4956 * struct.h: Include "print.h" and add prototype for
4958 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4959 print structures ourself.
4961 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4963 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
4964 before applying the handler in case it doesn't return.
4966 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
4968 * scmsigs.h, async.h: updated.
4970 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
4973 * posix.c (scm_uname): interpret only negative values as an error.
4974 Solaris normally returns a positive value.
4976 * script.c (scm_compile_shell_switches): if we are not going into
4977 an interactive repl, set scm_mask_ints to zero so that asyncs can
4980 * simpos.c (scm_system): don't ignore/unignore signals around
4983 * posix.c (scm_open_pipe): don't ignore/unignore signals around
4986 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
4987 done in boot-9.scm instead.
4989 * scmsigs.c, async.c: Major rewriting of signal handling code.
4990 (scm_sigaction): new procedure.
4991 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
4993 (scm_raise): return unspecified, throw error on failure.
4995 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4997 * regex-posix.c (scm_init_regex_posix): Register the "regex"
4998 feature, to help boot-9.scm decide whether to import the regex
5001 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5003 * eval.c: Include scmconfig.h at the beginning of the file so that
5004 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
5007 * regex-posix.c: #include "_scm.h" before conditionally #including
5008 <regex.h>; the former defines HAVE_REGCOMP.
5010 * regex-posix.c: #include <regex.h> conditionally, so the file is
5011 CPP'able (for dependency scanning) even on systems that don't have
5014 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5016 Add new R4RS-compliant syntax for keywords.
5017 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
5018 regardless of the setting of the `keywords' read option.
5019 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
5020 can be re-read no matter what the setting of the `keywords' read
5023 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
5025 Add support for POSIX regular expressions.
5027 * regex-posix.c, regex-posix.h: New files. (Some code
5028 is taken liberally from rx/rgx.c in the old Guile dist.)
5030 * init.c: Include regex-posix.h.
5031 (scm_boot_guile_1): Call scm_init_regex_posix.
5033 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
5034 Add regex-posix.[ch] sources.
5035 * Makefile.in: Regenerated.
5037 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
5038 to do this automatically? It didn't for me, bleh.)
5040 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
5042 * fports.c (print_pipe_port): New function.
5043 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
5044 latter doesn't even take the right arguments.
5046 * Makefile.am: Increment shared lib revision number. I think
5047 sometimes the uninstalled Guile finds the installed shared lib;
5048 Gord says doing this might help. As things turned out, I can't
5049 say whether it does.
5050 * Makefile.in: Regenerated.
5052 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
5053 passing it as the closure argument to scm_boot_guile. (Bill
5056 * ports.c (print_void_port, putc_void_port, puts_void_port,
5057 write_void_port, flush_void_port, getc_void_port, close_void_port,
5058 noop0): Use ANSI prototypes instead of K&R declarations, so the
5059 initialization of void_port_ptob gets aggressively type-checked.
5060 Fix arguments of print_void_port and write_void_port. (Bill

5094 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
5096 * script.c (scm_find_executable): Use prototype-style definition
5097 here; apparently it's not quite right to have const in a prototype
5098 and then use a K&R declaration. I wonder if stuff like this will
5099 go away if we compile with -Wrequire-prototypes, or whatever that
5100 is... (Bernard URBAN)
5102 * scmhob.h: New text from Bernard URBAN.
5104 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5106 * script.c: Don't #define const on hpux. Configure takes care of
5107 this. (Thanks to Larry Schwimmer.)
5109 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5110 decide whether to #include <unistd.h>, instead of listing a bunch
5111 of systems. Don't #include stdio twice. Removed dyked-out
5112 definition of scm_find_impl_file.
5114 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5116 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5117 library version info to 1:0.
5118 * Makefile.in: Regenerated.
5120 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

5124 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5125 throw.c: Update copyright years; these files have been worked on
5126 significantly in 1997, but only had copyright years for 1996.
5127 Also, change name of copyright holder on some from Mikael
5128 Djurfeldt to Free Software Foundation; he has signed papers
5129 assigning the changes to the FSF.
5131 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5132 reason not to give the user the option.
5134 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5135 Return #f on end-of-file when scanning table (i.e. when called
5136 with no arguments). Try to catch errors, when we can.
5137 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5139 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5140 external declarations. These are useful.
5142 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5144 * posix.c: don't include <sys/select.h> or define macros for
5145 select, since they were not used in this file.
5147 * filesys.c (scm_select): make the fifth parameter microseconds,
5148 not milliseconds. let the fourth parameter be either a real value
5149 or an integer or #f. The first, second and third arguments can
5150 now be vectors: the type of the corresponding return set will be
5152 (set_element, get_element): new static procedures.
5154 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5156 * strports.c (scm_eval_string): New function.
5157 (scm_eval_0str): Trivially re-implemented in terms of
5159 * strports.h (scm_eval_string): New extern decl.
5161 * net_db.c (h_errno): Add extern decl for this.
5163 * fports.c (local_pclose): New function.
5164 (scm_pipob): Use it in the initializer here.
5167 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5168 Use a meaningful error message when signalling an error. For
5169 this, scm_gethost must check h_errno rather than errno.
5171 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5173 * Makefile.in: Regenerated, using automake-1.1p.
5175 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5177 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5178 not SCM_UNSPECIFIED.
5180 * script.c (scm_compile_shell_switches): don't append (quit) if
5182 (scm_shell): call scm_exit_status and exit on the result of the
5185 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5187 Ensure that shared substrings are handled properly when passed to
5188 a system call or other foreign function. Many thanks to Tim
5190 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5191 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5192 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5193 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

5195 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
5196 (scm_display_error_message): use RO macros when strings may be RO.
5197 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
5198 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
5199 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

5203 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
5204 scm_strftime), vports.c (scm_make_soft_port): use
5205 SCM_COERCE_SUBSTR to make sure shared substrings are
5208 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5210 * error.c (scm_error): Add newline to error message.
5212 * init.c (scm_init_standard_ports): Doc fix.
5214 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5216 * dynl-shl.c: Completely replaced with new code from Bernard
5219 * script.c (scm_ice_9_already_loaded): New variable.
5220 (scm_compile_shell_switches): Use it.
5222 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5224 * filesys.c (scm_input_waiting_p): add missing third argument to
5227 * stime.c (scm_localtime): copy the result of localtime before
5228 calling gmtime in case they share a buffer.
5229 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5232 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5234 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5236 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5238 * Makefile.am (check-local): New target, which causes 'make check'
5239 to run gh_test_c and gh_test_repl, with some trivial input.
5240 * Makefile.in: Rgnrtd.
5242 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5244 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5247 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
5249 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
5250 sure how this was supposed to work.
5251 (scm_async_click): don't send SCM_TICK_SIGNAL.
5252 (scm_init_async): don't initialize %tick-thunk.
5254 * the following change doesn't affect the Scheme interface:
5255 gc-thunk is called at the end of garbage collection. however it's
5256 no longer implemented by pretending it's a signal.
5258 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
5259 system async corresponding to scm_gc_thunk.
5260 * async.h: declare scm_gc_async.
5261 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
5262 gc-thunk directly, instead of going through a signal handler.
5263 (scm_gc_async): new variable, points to the GC system-async.
5264 (scm_init_async): save the GC async as scm_gc_async instead
5265 of using system_signal_asyncs.
5266 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
5268 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
5270 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
5271 Don't screw up if we're interrupted.
5272 * Makefile.in: Regeneradet.
5274 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
5276 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
5278 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
5279 we're not using AM_INIT_GUILE_MODULE any more.
5280 * Makefile.in: Reneregated.
5282 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5284 Functions for finding variable bindings, grace à Tim Pierce.
5285 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
5286 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
5288 Get 'make dist' to work again.
5289 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
5290 * Makefile.in: Regenerated, like a surry without a fringe on top.
5292 Changes for reduced Guile distribution: one configure script,
5294 * configure.in, configure: Removed.
5295 * acconfig.h, acinclude.m4: Moved to parent directory, where the
5296 real configure script lives.
5297 * Makefile.in, scmconfig.h.in: Regenerated.
5299 * init.c: #include "script.h", to get prototype for script.c's
5302 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
5304 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
5305 scm_must_malloc, not raw malloc.
5307 * script.c (scm_compile_shell_switches): Dyke out debugging output
5310 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5312 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
5314 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
5315 system has them. Hope this is safe. Previously
5316 sys/timeb.h was included if HAVE_FTIME was defined or if
5317 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
5318 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
5320 * ioext.c (scm_setfileno): add missing third argument to
5321 scm_misc_error call.
5323 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
5325 * eq.c (scm_equal_p): Correctly compare strings of different
5326 varieties. (Thanks to Tim Pierce.)
5328 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
5330 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
5331 #! block comment must occur on a line all by itself.
5333 Move most of the guts of shell command processing into libguile,
5334 so guile.c can be very small (and eventuallly auto-generated. (I
5335 mean, generated mechanically, not self-generated. Hmm.))
5336 * guile.c, script.c, script.h: New source files.
5337 * init.c (scm_boot_guile_1): Call scm_init_script.
5338 * libguile.h: #include "script.h".
5339 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
5340 targets, for new executable.
5341 (libguile_la_SOURCES): Mention script.c.
5342 (modinclude_HEADERS): Add script.h.
5343 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
5344 not dynamic linking is enabled. This is because we're generating
5345 executables now. Move CY_AC_WITH_THREADS call after those, so the
5346 values of cy_cv_threads_libs captures the libs chosen above.
5347 * Makefile.in, configure, aclocal.m4: Regenerated.
5349 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
5350 We don't maintain this interface any more, and it just confuses
5353 * alloca.c: #include <scmconfig.h>, not <config.h>.
5354 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
5355 it'll get included in disties.
5357 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5359 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
5360 be distributed, because they confuse people.
5361 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
5363 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
5365 * configure.in: check for presence of gethostent (not present on
5366 OpenBSD by default).
5367 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
5368 * configure, scmconfig.h.in: Regenerated.
5370 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5372 * backtrace.c (scm_backtrace): Split message string across
5373 newlines properly. GCC is more tolerant of this than other
5376 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
5378 Merge threads directory into libguile.
5379 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5380 threads.h: New source files.
5381 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
5382 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
5384 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5385 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5386 coop-threads.c.cygnus, coop-threads.h.cygnus.
5387 * configure.in: If we're using threads, include threads.o in
5389 * _scm.h, libguile.h: threads.h lives in this directory now.
5390 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5391 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5392 currently used, but brought along for information's sake.
5393 * ChangeLog-threads: log from old 'threads' directory.
5394 * Makefile.in, configure: Rebuilt.
5396 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5398 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5401 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5403 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5405 Merge GH interface library into libguile.
5406 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
5407 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5408 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5409 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5411 (EXTRA_libguile_la_SOURCES): ... here.
5412 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5413 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5414 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5415 New variables, describing how to build the gh test programs.
5416 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5417 build the test programs, and we probably should have been linking
5418 libguile.la against them all along, to support AIX shared libs.
5419 Add cflags for threads to CFLAGS; add libs for threads to new
5420 variable THREAD_LIBS, used in Makefile.am.
5421 * ChangeLog-gh: log from old `gh' subdirectory.
5422 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5424 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5426 * acconfig.h: Undo change of Apr 9; including the definition of
5427 PACKAGE in the guile headers conflicts with applications' own
5429 * scmconfig.h.in: Regenerated.
5431 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>
5433 * filesys.c (scm_fcntl): New function from Roland McGrath.
5434 (scm_init_filesys): New symbols for use with fcntl.
5435 * filesys.h: Added prototype.
5437 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
5438 when PROC is receiving no arguments.
5440 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5442 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5443 have S_IFSOCK. This is the case under Ultrix.
5445 * posix.c (scm_status_exit_val, scm_status_exit_val,
5446 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5447 Ultrix versions of WIFSTOPPED, etc., which assume that their
5448 arguments are lvalues (hmm).
5450 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5452 * eval.c: Doc fixes.
5454 * throw.c: Doc fixes; rearranged.
5456 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
5458 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
5460 * acconfig.h: Added entry for PACKAGE.
5461 * scmconfig.h.in: Regenerated.
5463 Changes to work with automake-1.1n, which has better libtool support.
5464 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5465 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5467 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5469 * Makefile.in: Rebuild.
5471 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5473 * stime.c (scm_mktime): take an optional zone argument.
5474 (scm_localtime): check putenv return value.
5475 (scm_strftime, scm_strptime): moved from posix.c. move #include
5477 stime.h, posix.h: update prototypes.
5478 (bdtime2c, setzone, restorezone): new static procedures.
5479 (scm_mktime, scm_strftime): use them.
5480 (scm_strftime): don't call mktime before strftime. Use
5481 filltime for return value.
5482 (filltime): convert NULL zname to #f.
5483 (scm_strptime): return a count of characters consumed, not
5484 the remaining string.
5486 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5488 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.

5491 Uncomment localtime and mktime.
5493 * configure.in: add AC_STRUCT_TIMEZONE.
5495 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5497 * stime.c (scm_init_stime): don't define ticks/sec.
5498 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5499 return value problem and is still portable.)
5501 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5503 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5504 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5505 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5506 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5507 cpp_err_symbols.c): Corresponding changes.
5508 * Makefile.in: Regenerated.
5510 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5512 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5513 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5514 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5515 * putenv.c: new file, from sh-utils 1.12.
5517 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5518 since allocation isn't for Scheme objects.
5519 (scm_putenv): copy strings before placing in the environment.
5521 * stime.c (scm_current_time): throw an error if time returns -1,
5522 instead of returning #f.
5523 (scm_get_internal_real_time, scm_get_internal_real_time): use
5524 scm_long2num for return value instead of SCM_MAKINUM.
5526 * stime.h: prototypes updated.
5528 * stime.c (scm_time_in_msec): apparently unused, deleted.
5530 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5532 * configure.in: check for gettimeofday.
5534 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5535 which may be more usefully portable than a gettimeofday interface.
5537 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5539 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5541 * Makefile.in: Regenerated.
5543 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5545 * stime.c (filltime): recovered static procedure.
5546 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5549 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5550 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5552 * posix.c (scm_mknod): split the mode argument into type and perms
5553 arguments, like the extra fields returned by stat.
5555 * fports.c (scm_pipob): set the close, free and print procedures.
5556 (scm_close_pipe): new procedure.
5558 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5559 define them in boot-9.scm
5561 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5563 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5564 wan't defined. Don't include fd.h.
5566 * Previously fd.h was regenerated whenever configure was run,
5567 forcing a couple of files to be recompiled.
5569 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5570 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5571 Check for _fileno as well as _file.
5573 * ioext.c: don't fd.h.
5574 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5577 * Change the stratigy for getting information about errno
5578 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5579 generating lists of symbols during the build process, which will
5580 not always work, include comprehensive lists in the distribution.
5581 To help keep the lists up to date, the "check_signals" and
5582 "check_errnos" make targets can be used.
5584 * configure.in: don't check for a command to extract errno codes.
5585 * Makefile.am: update file lists, remove errnos.list and errnos.c
5586 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5587 check_errnos targets.
5588 (CLEANFILES): remove errnos.c and errnos.list, add
5589 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5590 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5591 * errnos.default: deleted.

5594 * cpp_err_symbols, cpp_sig_symbols: new files.
5595 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5596 * error.c (scm_init_error): #include cpp_err_symbols instead of
5598 * posix.c (scm_init_posix): don't intern signal symbols. #include
5601 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5603 * strop.c (scm_i_index): allow the lower bound to be equal to the
5604 length of the string, so a null string doesn't always give an error.
5606 * posix.h: new prototypes.
5607 * posix.c (scm_status_exit_val, scm_status_term_sig,
5608 scm_status_stop_sig): new functions, as in scsh. They break down
5609 process status values as returned by waitpid.
5611 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5613 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5614 configure doesn't know about it.
5616 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5618 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5620 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5621 which defines C variables with global linkage.
5623 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5625 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5628 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5630 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5631 has time to check why this doesn't work well with continuations.
5633 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5635 * Fix shell syntax error; some shells won't tolerate
5636 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5638 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5640 * posix.c (scm_uname): throw an error if uname fails instead
5643 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5645 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
5648 * async.c (scm_ints_disabled): definition moved from error.c.
5650 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5652 * acconfig.h: Removed PACKAGE.
5654 * scmconfig.h.in: Regenerated.
5656 * snarf.h: g++ says it's non-portable not to specify the first
5657 argument in a varargs declaration. I introduced the first
5658 argument by using preprocessor conditionals.
5660 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5662 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5663 (scm_freopen): use RO string macros for filename and modes.
5664 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
5666 * posix.c (scm_getgrgid): simplify conversion of name to C string.
5667 (scm_mknod): use RO string macros for path.
5669 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
5670 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5672 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5673 use SCM_ROSTRINGP and SCM_ROCHARS.
5675 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5677 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5680 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5681 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5682 support for byte vectors.
5684 * print.c (scm_iprin1): Limit number of vector elements printed
5685 according to pstate->length.
5687 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5689 * backtrace.c (scm_display_error_message): don't segv if message
5692 * error.h: prototype for scm_error_scm.
5694 * error.c (scm_error_scm): new procedure, reimplements scm-error
5695 in C and uses scm_error.
5697 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5699 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5700 pointer to the Scheme variable read-hash-procedures and intern it
5701 in scm_init_read. Modify scm_read_hash_extend and
5702 scm_get_hash_procedure to use the pointer.
5704 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5706 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5707 (SCM_KEYWORD_STYLE): defined.
5709 * read.c (scm_read_opts): add a keywords option. This isn't a
5710 boolean option, in case someone wants to add support for DSSSL
5712 Setup scm_keyword_prefix symbol.
5713 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5715 I've left keyword support disabled by default, since it doesn't
5716 seem to break the module system and it gives R4RS standard behaviour.
5717 It can be reactivated with (read-set! keywords 'prefix).
5719 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5721 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5722 before constructing arbiter.
5724 * eval.c (scm_m_define): Bugfix: Check that the object is a
5725 closure before setting the procedure property!
5727 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5729 * ports.c: Removed `ungetc-char-ready?'.
5731 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5733 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5734 (idea from Mikael: make it a pair so scm_permanent object only
5736 (scm_read_hash_extend): don't call scm_permanent_object.
5737 (ideas from Mikael): if chr is already in the list, replace its
5738 procedure instead of appending it again. If proc is #f, remove
5740 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5742 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5744 * gdbint.c (gdb_read): update scm_lreadr usage.
5746 * load.h: update prototypes.
5748 * load.c (scm_primitive_load, scm_read_and_eval_x,
5749 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
5751 * read.h: add prototype for scm_read_hash_extend. Change args for
5754 * read.c (scm_read_hash_procedures): new variable.
5755 (scm_read_hash_extend): new procedure.
5756 (scm_get_hash_procedure): new procedure.
5757 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5758 for extended # processing.
5759 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5760 scm_read_token): remove case_i, sharp arguments. Change callers.
5762 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5764 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5765 (SCM_CASE_INSENSITIVE_P): define.
5767 * read.c: add case-insensitive option to scm_read_opts.
5768 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5769 to determine whether to convert symbol case.
5770 (default_case_i): definition removed.
5771 * read.c (scm_read_token): if case_i, downcase ic before doing
5774 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5776 * configure.in: Added configuration option `guile-debug'.
5777 Configure with --enable-guile-debug if you want a bunch of extra
5778 functions used for debugging when developing Guile.
5780 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5782 * procs.c (make-cclo): New undocumented debugging procedure: Make
5783 compiled closure with internal procedure PROC and length LENGTH.
5784 Only compiled if GUILE_DEBUG is defined.
5786 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5788 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5790 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5792 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5793 with 3 or more args internally to the evaluator.
5795 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5797 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5798 with 3 or more args internally to the evaluator. This is mainly
5799 because we don't want to pass entry and exit points of the
5800 debug support twice, but it also seems to increase the speed of
5801 the evaluator for such calls (e. g. (+ 1 2 3)).
5803 * backtrace.c (scm_display_application): New procedure:
5804 display-application; Set fancy printing parameters individually
5805 for different types of display (backtrace, error, application).
5806 (These should of course be customizable!)
5808 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5809 clear the CHECK-flags.
5811 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5813 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5815 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5817 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5818 from pairs with a GLOC in the car.
5820 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5821 otherwise `symbol-hash' will behave badly.
5822 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5823 we get segmentation fault!
5825 * symbols.c: Added #include "weaks.h". New functions:
5826 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5827 moved to an extraneous library when we split libguile.)
5829 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5831 * filesys.c (scm_stat): stat now takes fport arguments too as
5832 documented in the manual.
5834 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5836 * debug.c (scm_single_step): Bugfix: Call continuation with
5837 scm_call_continuation instead of throwing to it.
5839 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5841 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5842 argument wasn't declared to be optional.
5844 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5846 * stime.c (scm_init_stime): Add feature "current-time".
5848 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5850 * throw.h: prototype for scm_exit_status.
5851 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5852 args to derive an exit status. Allows (quit) to work from a
5854 (scm_exit_status): new function.
5857 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5859 * eval.c (scm_deval): Removed some old code.
5860 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5862 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5865 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5868 * procs.c: Introduce the existent C function scm_thunk_p at the
5869 Scheme level as well.
5871 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5873 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5874 used from C to easily lookup the value of a symbol in the current
5877 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5879 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5880 scm_init_unif in this file. This will also fix a previous problem
5883 * configure.in: Added AM_MAINTAINER_MODE
5885 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5887 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5890 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5892 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5893 source files that are not always included in libguile but should
5894 have their dependencies calculated by automake. This variable is
5895 recognized by automake, no further magic is needed.
5896 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5897 to deal exclusively with *.lo files, as it seems. The *.o files
5898 are built automatically when the corresponding *.lo file gets
5901 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5903 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5906 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5908 * unif.c (scm_array_set_x): minor change to argument error checking.
5910 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5912 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5913 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5914 They should only be included in the library at configure.in's
5916 (libguile_la_LDADD): Include the appropriate .lo files here.
5917 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5918 so we know when to build them (and their .lo bretheren).
5919 * configure.in (LIBLOBJS): New substituted variable. We let
5920 configure decide which .o files to include in LIBOBJS, and then
5921 put the corresponding list of .lo files in LIBLOBJS. The latter
5922 is what we pass to libtool.
5923 * Makefile.in, configure: regenerated.
5925 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5927 * symbols.c (scm_sysintern0): New function. Contains the core of
5928 old scm_sysintern but doesn't take a second value argument.
5929 (scm_sysintern): Now uses scm_sysintern0.
5930 (scm_sysintern_no_module_lookup): Renamed to
5931 scm_sysintern0_no_module_lookup and doesn't take a second value
5932 argument any longer.
5934 * symbols.h (scm_sysintern0: Added declaration.
5936 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5937 scm_sysintern when interning option keys. Otherwise we risk
5938 destroying the values of already interned variables.
5940 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5941 scheme-level boolean (use SCM_NFALSEP).
5943 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5945 (scm_backtrace): New function. (C version of old function from
5946 boot-9.scm) Motivation: Make it possible to display backtraces
5947 without depending on boot-9.scm. (I'm uncertain if this
5948 motivation is good enough...)
5950 * root.h (scm_root_state): Add member the_last_stack_var.
5951 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5953 * root.c (mark_root): Mark scm_the_last_stack_var.
5955 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5958 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5960 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5961 1. mark_lazy_catch didn't mark the smob.
5962 2. Both functions above have standard variants:
5963 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5964 free_lazy_catch --> scm_free0.
5966 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5968 * throw.c (scm_internal_lazy_catch): New function.
5969 (scm_lazy_catch): Rewritten to use it.
5970 (scm_ithrow): Handle the new lazy catch representation.
5971 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
5972 that doesn't have a jmpbuf is a lazy catch clause.
5973 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
5974 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
5975 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
5977 (scm_init_throw): Register the new lazy-catch smob type.
5978 * throw.h (scm_internal_lazy_catch): decl for new function.
5980 * throw.c (scm_internal_catch): Doc fixes.
5982 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
5983 configure.in. Including this might cause problems if applications
5984 that link against libguile include their own copies of alloca, but
5985 if they're using autoconf, they should be adding libguile to LIBS
5986 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
5987 the copy in libguile, and things will be okay. (I think.)
5989 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5991 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
5993 strop.h: move prototypes too.
5995 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5997 * posix.c (scm_init_posix): don't intern EINTR since it's now done
6000 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
6001 etc. I deleted them from filesys.c long ago, but didn't
6002 notice they were here too (although ineffective since
6003 sys/stat.h wasn't included).
6005 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
6007 * eval.c: Don't define alloca in GCC case. gcc will automatically
6008 use __builtin_alloca if appropriate.
6010 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
6012 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
6013 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
6014 that values of automatic variables are preserved. See comments
6015 for safe_setjmp for details.
6017 Change from Thomas Morgan:
6018 * variable.c: Include eq.h.
6019 (var_equal): New function.
6020 (variable_smob): Use var_equal as the discriminator for variables.
6022 * throw.c (s_throw): Remove extraneous declaration.
6024 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
6025 * eval.c: Add necessary CPP cruft to support that.
6026 * configure, Makefile.in, scmconfig.h.in: regenerated.
6028 Change from Thomas Morgan:
6029 * procprop.c (scm_procedure_properties): Convert the Scheme
6030 boolean returned by scm_procedure_p into a C boolean before using
6031 it as a condition for SCM_ASSERT.
6032 (scm_procedure_property): Likewise.
6034 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
6035 indications of Unixness.
6038 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6040 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
6042 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6044 * read.c (scm_lreadr): use scm_misc_error to improve one of the
6045 "unknown # object" error messages.
6047 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
6048 (scm_i_index) and declare it static. Add a 'direction' argument
6049 to indicate what way the search should go.
6050 (scm_i_index): throw out-of-range error instead of wrong-type-arg
6052 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
6053 strop.h: remove scm_i_index, scm_i_rindex prototypes.
6055 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6057 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
6059 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
6060 to avoid clash with various scsh forks.
6062 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
6064 The following two changes (ramap.c, throw.c) are motivated by the
6065 apparent unportability of forward declarations of static arrays of
6066 the form `static foo bar[];'.
6068 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
6069 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
6071 * throw.c (scm_throw): Moved above scm_ithrow.
6073 * options.h: Removed the extern declarations of scm_yes_sym and
6074 scm_no_sym since these are static.
6076 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6078 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6080 * Makefile.am: remove AWK=@AWK@.
6081 Add a rule for generating errnos.list.
6082 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6084 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6085 don't extract errnos, just set a variable (avoids the
6086 need to recompile error.c just because configure is run.)
6088 * unif.h: update prototypes.
6089 * unif.c (scm_uniform_array_read,write): change the offset and
6090 length arguments to start and end, for consistency.
6092 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6094 * ioext.h: update prototypes.
6095 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6096 scm_read_line_x, it's a more general procedure using an
6097 interface from scsh. read-line and read-line! are now defined
6099 Note that the new read-line trims the terminator
6100 by default, previously it was appended to the returned string. An
6101 optional argument specifies how to process the terminator (scsh
6102 compatible). For the old behaviour: (read-line port 'concat).
6103 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6104 returns a pair, but is converted to multiple values if the scsh
6107 socket.h: update prototypes.
6108 * socket.c (scm_recvfrom): for consistency with other procedures,
6109 take start and end as separate optional arguments.
6110 (scm_recv, scm_recvfrom): don't allow the second argument
6111 to be a size, only a buffer. Change the scheme names to
6112 recv! and recvfrom!. Don't return the buffer.
6114 * ioext.h, posix.h: move prototypes too.
6115 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6116 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6117 "read.h" and "unif.h".
6118 * ioext.c: include "chars.h"
6120 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6122 * dynl.c: The dynamic linking and module registration functions
6123 are now defined even when dynamic linking is not available for the
6124 host system. Some of their functionality can be done without
6125 dynamic linking; when it's really needed, they throw errors.
6127 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6129 * configure.in: Only define DYNAMIC_LINKING when one of the system
6130 dependent functions is detected.
6131 * dynl.c (scm_dynamic_func): New function to get the address of a
6132 function in a dynamic object.
6133 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6134 produced by scm_dynamic_func as the thing to call.
6136 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6138 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6139 (scm_register_module_xxx, scm_registered_modules,
6140 scm_clear_registered_modules): New functions.
6142 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6144 * symbols.c (scm_sysintern): Renamed to
6145 scm_sysintern_no_module_lookup.
6146 (scm_sysintern): New function to take the place of the old
6147 scm_sysintern. It uses the current toplevel lookup closure to give
6148 the symbol its value. This is a temporary hack to put packages
6149 like gtcltk into their own module.
6150 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6151 us whether `scm_top_level_lookup_closure_var' has been initialized
6153 * eval.c (scm_init_eval): Set it.
6155 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6157 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6158 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6160 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6162 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6163 scm_sys_dup): deleted: FD capability will be added to other
6165 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6166 scm_fd_free, fd_smob, scm_intern_fd.
6167 (scm_open): renamed from scm_sys_open. Return a port instead of
6168 an FD object. Make the mode argument optional.
6169 (scm_sys_create): deleted, it's just a special case of open.
6170 (scm_init_filesys): move interning of constants O_CREAT etc.,
6171 here (were previously using SCM_CONST_LONG macro).
6172 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6174 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6175 include "fports.h" and <stdio.h>
6176 (scm_stat, scm_select): don't support FD objects.
6178 * error.h: adjust scm_syserror_msg prototype.
6179 * error.c (scm_syserror_msg): take an extra argument for errno.
6180 Using the global value didn't always work, since it could be
6181 reset by procedure calls in the message or args arguments.
6183 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6184 I don't understand why the check was there (and what about the
6187 * strop.c (scm_string_copy): allow shared substrings to be copied.
6189 * unif.h: corresponding change to prototypes.
6190 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6191 recognize two new optional arguments: offset and length. Allow
6192 the port argument to be an integer (file descriptor, for scsh).
6193 Include <unistd.h> for "read" prototype.
6195 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6197 * socket.c: don't include filesys.h.
6199 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6201 * Makefile.am: add AWK=@AWK@ (?)
6203 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6205 Add a rule to generate errnos.c from errnos.
6206 * error.c (scm_init_error): include errnos.c.
6207 * errnos_cnvt.awk: new file, converts the list of errno codes to
6209 * errnos_get.c: new file.
6210 * errnos.default: new file, contains errnos to try if they can't
6211 be extracted from errno.h.
6212 * configure.in: if using GCC, try and extract errno codes from
6216 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6218 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6219 * Makefile.am: Made libguile into a libtool library.
6220 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6221 Set libtool_libs to indicate that libguile is a libtool library.
6222 See guile/ChangeLog for details.
6223 * .cvsignore: ignore "*.lo", the libtool library objects.
6225 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6227 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6228 use htons in getservbyport argument.
6230 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6232 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6233 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6236 * objprop.c (scm_object_property): No need to take the CDR of the
6237 value returned by scm_object_properties, since Aug 20 change.
6239 * configure.in: When checking for struct linger, #include
6240 <sys/types.h> as well as <sys/socket.h>. I've never known
6241 <sys/types.h> to cause any portability problems, and Solaris's
6242 <sys/socket.h> needs it.
6243 * configure: Rebuilt.
6245 I think the Sun compiler has chosen a perverse way to interpret
6246 ANSI declarations combined with K&R definitions. We'll
6247 appease it a little bit. But when it invades France, we fight.
6248 * print.c (scm_iprlist): Change 'tlr' argument to an int.
6249 * print.h (scm_iprlist): Here too.
6250 * numbers.c (scm_divbigdig): Change definition to match
6251 declaration in numbers.h.
6252 * unif.c (scm_makflo): Change definition to match declaration in
6255 * init.c (scm_boot_guile): Don't return the value of
6256 scm_boot_guile_1. This function doesn't return a value;
6257 scm_boot_guile_1 doesn't return a value (or return at all).
6259 * eval.c (unmemocopy): Add a semicolon to appease the Sun
6262 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
6263 compile. I have a feeling this function is a bad idea anyway ---
6264 one should always test for features, not systems.
6266 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
6267 semicolons. Only pure luck kept this from being noticed earlier.
6269 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
6271 * socket.c (scm_recvfrom): Added missing semicolon.
6273 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6275 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
6276 the buffer and start and end positions for scsh networking
6279 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
6281 * configure.in: Revert previous change to this file; the problem
6282 is due to transient automake weirdness.
6283 * configure: Rebuilt.
6285 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
6286 PLUGIN/guile.libs. configure generates the latter from the former.
6287 * Makefile.in: Rebuilt.
6289 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
6290 need this if we install scripts, like guile-snarf.
6291 * configure: Rebuilt.
6293 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6295 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
6297 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
6299 * socket.c (scm_addr_vector): fix faulty scm_listify.
6301 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
6303 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
6304 style block comment is no longer considered an error.
6306 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
6308 * PLUGIN/guile.libs.in: New file.
6309 * PLUGIN/guile.libs: Removed from repository.
6310 * configure.in: Create PLUGIN/guile.libs from
6311 PLUGIN/guile.libs.in. This is for including additonal libraries
6312 needed for dynamic linking.
6313 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
6314 instead of PLUGIN/guile.libs.
6316 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
6318 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
6320 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
6321 occurrences of the given element from the list, not just the
6322 first. This is how the Emacs Lisp functions behave, how the
6323 analogous Common Lisp functions behave, and (I believe) how the
6324 older Maclisp functions worked. I realize that this change may
6325 break code, but it seemed better to break it before the Guile
6328 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
6329 Their prototypes were already present in gc.h, but they weren't
6331 (scm_init_storage): Initialize scm_protects.
6332 * root.c (scm_protects): New element of scm_sys_protects.
6334 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
6336 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6338 * libguile.h: Added #include "libguile/net_db.h".
6340 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
6341 30 change. That file is only meant for communication between the
6342 configuration process and load.c. If code linked against libguile
6343 wants to get at the paths mentioned in libpath.h, it can call
6344 functions declared in load.h.
6346 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6348 * libguile.h: Removed #include "libguile/fdsocket.h"
6350 * net_db.c: Added #include <sys/socket.h>.
6352 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
6354 * filesys.c (scm_input_waiting_p): use select in preference to
6355 FIONREAD, since the latter doesn't detect EOF.
6356 Throw error if neither select nor FIONREAD available.
6358 * socket.c (scm_connect): take a port, not a fd object.
6359 (scm_fill_sockaddr): throw an error if fam is not recognised.
6360 (scm_bind): use scm_fill_sockaddr.
6361 (scm_listen): take a port, not a fd object.
6362 (scm_accept): take and return a port. return #f in the car if
6363 address can't be got
6364 (scm_sock_fd_to_port): new procedure.
6365 (scm_socket): use scm_sock_fd_to_port.
6366 (scm_addr_vector): throw error if unrecognised address type.
6367 take an extra argument with the calling procedure name.
6368 (scm_getsockname): take a port. return #f if address can't be got.
6369 (scm_getpeername): take a port. return #f if address can't be got.
6370 (scm_recvfrom): take a port. return #f for address component if can't
6372 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6373 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6375 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6377 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6378 use separate data pointers, to allow them to be designed
6379 independently and reused.
6380 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6381 Renamed from catch_body, catch_handler, and uncaught_throw; made
6383 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6385 (scm_catch): Use the above.
6386 (scm_throw): Don't bother printing a message for an uncaught
6387 throw; we establish a default handler in init.
6388 * throw.h (scm_internal_catch): Prototype updated.
6389 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6391 (struct scm_body_thunk_data): New structure, used as data
6392 argument to scm_body_thunk.
6393 * init.c (struct main_func_closure): New structure, packaging up
6394 the data to pass to the user's main function.
6395 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6396 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6397 scm_internal_catch to establish a catch-all handler, using
6398 scm_handle_by_message. This replaces the special-case code in
6400 (invoke_main_func): Body function for scm_internal_catch; invoke
6401 the user's main function, using the main_func_closure pointer to
6402 decide what to pass it.
6403 * root.c (struct cwdr_body_data): Remove handler_proc member.
6404 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6405 (cwdr_handler): Removed.
6407 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6409 * socket.h (SCM_P): update bind prototype.
6410 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6411 include "feature.h".
6412 (scm_socket): return a port, not a file descriptor object.
6413 include "fports.h" and <unistd.h>
6414 (scm_bind): take a port, not a file descriptor object.
6415 take an extra argument for address args.
6417 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6418 INADDR_NONE, INADDR_LOOPBACK.
6420 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6422 * init.c: include net_db.h and not fdsocket.h.
6423 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6425 * Makefile.am: corresponding changes.
6426 * socket.h: renamed from fdsocket.h, fix names.
6427 * net_db.h: renamed from socket.h, fix names.
6428 * socket.c: renamed from fdsocket.c.
6429 remove _sys from procedure names.
6430 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6431 add "socket" to features list.
6432 * net_db.c: renamed from socket.c.
6433 remove _sys from procedure names.
6434 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6435 add "net-db" to features list.
6436 include "net_db.h". don't include <sys/socket.h> or
6439 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6441 * tags.h (scm_tags): Removed comma at end of last enumerator.
6443 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6445 Don't use GCC extensions to allocate space for debugging frames.
6446 (Here he goes again! Why do we put up with this?!)
6447 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6448 an scm_debug_info structure, not an in-line array of them. Add
6449 'info' member, to say how many vect elements we've used, for eval
6451 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6452 a new variable debug_info_end to mark the end of vect, instead of
6453 the address of the 'info' pointer itself.
6454 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6455 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6456 (SCM_APPLY): Explicitly allocate space for debug.vect.
6457 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6458 * stacks.c: Adjusted for new debug frame structure.
6459 (RELOC_INFO, RELOC_FRAME): New macros.
6460 (stack_depth, read_frames): Use them, and new scm_debug_frame
6461 element 'info', instead of magically knowing that eval frames have
6462 an info pointer sitting after vect.
6463 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6465 (scm_init_stacks): Formatting tweaks.
6467 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6469 Give GCC more control flow information, so it can be sure that
6470 variables aren't used uninitialized.
6471 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6472 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6473 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6474 scm_misc_error): Tell GCC that these functions never return.
6475 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6476 out the field type, call abort if SCM_ASSERT returns, to placate
6478 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6479 scm_wta ever returns. We can't handle this case anyway, and this
6480 gives the optimizer more information.
6481 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6482 scm_wta ever returns.
6484 In some cases, the code is fine, but GCC isn't smart enough to
6485 figure that out; this usually happens when one variable is only
6486 initialized and used when a particular condition holds true, and
6487 we know that condition will never change within a given invocation
6488 of the function. In this case, we simply initialize the variables
6489 to placate the compiler, hopefully to a value which will cause a
6490 crash if it is ever actually used.
6491 * print.c (scm_iprin1): Initialize mw_pos.
6492 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6493 * throw.c (scm_ithrow): Initialize dynpair.
6494 * unif.c (scm_uniform_vector_ref): Initialize cra.
6495 * struct.c (init_struct): Initialize prot.
6496 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6498 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6499 if EXPR contains no expressions.
6501 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6503 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6504 cause an infinite loop (???). So much for the algebraic
6505 equivalency of variable-sized arrays and alloca...
6507 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6509 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6510 a SCM boolean, not a C boolean.
6512 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6514 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6515 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6516 rules for raising scm_mtrigger. Previously, unfortunate but not
6517 unlikely circumstances could result in almost constant invokation
6518 of the gc. Now, this situations should be less likely, but they
6519 are not prevented completely.
6521 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6523 * numbers.c (scm_fuck): Procedure removed; looks like old test
6525 * numbers.h: Prototype removed.
6527 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6529 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6530 array to a pointer, to match my Nov 21 change in eval.c.
6532 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6534 * libguile.h: Added #include "libguile/backtrace.h", #include
6535 "libguile/stacks.h".
6537 * strings.c (scm_string scm_make_string scm_string_ref
6538 scm_string_set_x scm_string_equal_p scm_string_append):
6539 Bugfix according to scm patch from Aubrey Jaffer:
6540 Corrected long-standing
6541 (not (eqv? (integer->char 128)
6542 (string-ref (make-string 1 (integer->char 128)) 0)))
6543 bug found by John Kozak <jk@noontide.demon.co.uk>.
6545 * strports.c, strports.h: Make scm_eval_0str return the value of
6546 the last expression evaluated (previously, it returned void).
6548 * strports.c, strports.h: New function: scm_read_0str. Does what
6551 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6553 * simpos.c (scm_getenv): return #f if string can't be found in the
6554 environment instead of throwing an exception, for compatibility
6555 with numerous other systems.
6557 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6559 * Makefile.am (.c.x): Use guile-snarf.
6560 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6562 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6564 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6566 * backtrace.c (scm_display_error_message): Made non-static, and
6567 renamed from display_error_message.
6568 * backtrace.h (scm_display_error_message): Added extern decl.
6569 * throw.c (uncaught_throw): Use it to display the error message.
6571 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6573 * inet_aton.c: Use #if 0, not #ifdef 0.
6575 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6577 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6578 to convert the returned value.
6579 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6580 the offset argument.
6582 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6584 Add new interface to catch/throw, usable from C as well as
6586 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6587 (scm_internal_catch): New function, replaces...
6588 (scm_catch_apply): Deleted.
6589 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6590 mechanism which is a bit more code, but can be used nicely from C
6591 and implement the Scheme semantics as well.
6592 (scm_internal_catch): This is the replacement; it's named after
6593 the analogous function in Emacs.
6594 (scm_catch): Reimplemented in terms of the above.
6595 (struct catch_body_data, catch_body, catch_handler): New
6596 functions, used by scm_catch.
6597 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6598 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6599 support for new cwdr.
6601 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6604 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6606 * acconfig.h: Added DYNAMIC_LINKING symbol.
6607 * configure.in: Add option and checks for dynamic linking.
6608 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6609 dynl.h: New files for dynamic linking support.
6610 * Makefile.am (libguile_a_SOURCES):
6612 (modinclude_HEADERS): Added "dynl.h".
6613 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6615 * init.c (scm_boot_guile_1): Call
6616 scm_init_dynamic_linking to initialize dynamic linking support.
6618 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6620 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6621 (as we Schemers say). It needs to be global, so that I can tweak
6622 it for the proper operation of unexec.
6623 (scm_boot_guile_1_live): New variable, see above.
6625 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6627 * guile-snarf.sh: Removed.
6628 * PLUGIN/guile.libs: Added dependency for -lm.
6629 * acinclude.m4: Renamed from aclocal.m4.
6630 * PLUGIN/greet: Removed.
6631 * Makefile.am, aclocal.m4: New files.
6632 * configure.in: Updated for Automake.
6634 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6636 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6637 and not top_level_lookup_thunk_var.
6639 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6641 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6643 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6645 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6646 Scheme function, instead of syntax. Single argument is now a
6649 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6651 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6652 scm_ra_divide): Properly terminate statements passed as arguments
6653 to IVDEP macros. (Thanks to Bernard Urban.)
6655 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6656 with non-constant sizes. (Thanks to Bernard Urban.)
6658 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6660 It's an "eval closure", not an "eval thunk." A thunk is a
6661 function of no arguments.
6662 * root.h (struct scm_root_state): Renamed
6663 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6664 (scm_top_level_lookup_closure_var): Renamed from
6665 scm_top_level_lookup_thunk_var.
6666 * root.c (mark_root): Uses changed.
6667 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6668 * init.c (scm_start_stack): Uses changed.
6669 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6670 Change scheme-visible name to *top-level-lookup-closure* from
6671 *top-level-lookup-thunk*.
6673 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6675 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6676 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6678 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6680 * gc.c (struct scm_heap_seg_data): Doc fixes.
6682 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6683 sweeping. Then, prepend each segment's free cells to its
6684 freelist, rather than wiping out the old value. (Thanks to Marius
6687 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6688 scm_check_freelist, scm_debug_newcell): New functions and
6689 variables, for debugging freelist problems.
6690 * pairs.h (SCM_NEWCELL): New debugging version added.
6691 * gc.h (scm_debug_newcell): Added extern declaration, used by
6692 debugging version of SCM_NEWCELL.
6694 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6696 On some systems <libc.h> conflicts with <unistd.h>, and should not
6697 be #included at all.
6698 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6699 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6700 * configure.in: Call it.
6701 * posix.c, filesys.c: Use its results to decide whether or not to
6703 * configure, scmconfig.h.in: Rebuilt with autoconf and
6706 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6708 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6709 pointer to the stdio stream before calling scm_setbuf0, so the
6710 latter will be able to retrieve it. I'm surprised this didn't
6711 segfault earlier. (Thanks to Christopher Lee.)
6713 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6715 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6718 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6720 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6721 number of stack narrowing specifier pairs. The first specifier in
6722 a pair controls inner border, the second the outer border. A
6723 number means cut that number of frames, a procedure object means
6724 cut until that object is found in operator position in a frame.
6726 * root.c (cwdr): Bugfix.
6728 * read.c: Recording of positions disabled by default.
6730 * procs.c (scm_closure_p): New function.
6732 * posix.c (scm_tmpnam): New function.
6734 * load.c: Added #include "throw.h".
6735 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6738 * load.c, load.h (scm_read_and_eval_x): New function.
6740 * eval.c: Renamed debug option "deval" to "debug".
6742 (scm_eval_x): `eval!' is no longer accessible from the scheme
6743 level. Motivation: We can't allow operations which introduce
6744 glocs into the scheme level. Guile's type system can't handle
6745 these as data. Use `eval' or `read-and-eval!' as replacement.
6747 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6748 SCM_CONSP since this is a macro!; Set vframe.prev to
6749 scm_last_debug_frame instead of 0. In this way we can look
6750 "above" the virtual start stack frame if we wish.
6751 (scm_debug_hang): New function: Useful for debugging Guile in
6752 certain tricky situations. Will probably be removed later...
6754 * debug.h: Changed semantics of debug option "backtrace". This
6755 option now only indicates whether we want automatic backtrace at
6758 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6760 * ports.c: #include "filesys.h"
6761 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6763 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6764 Motivation: This is system specific code which is related to file
6765 I/O. It also may use select. Added code by Gary Houston to
6766 detect presence of character in stdio buffers.
6768 * libguile.h: #include "libguile/libpath.h"
6770 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6771 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6772 SCM_SITE_DIR; Install libpath.h among the other include files.
6774 * load.c, load.h (scm_sys_package_data_dir): New function.
6776 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6778 * stacks.h: Bugfix: Don't use tail-array length field as stack
6779 length field! This screwed GC.
6781 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6783 * _scm.h: Added #ifndef around definition of macros min and max.
6785 * __scm.h: Added hooks for threads to plugin to in ints protection
6786 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6787 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6788 the main code in these macros duplicated and spread over multiple
6789 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6790 SCM_THREAD_SWITCHING_CODE.
6792 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6794 * snarf.h: New file.
6795 * guile-snarf.sh: New file.
6796 * Makefile.in (inner_h_files): Added snarf.h
6797 (ancillary, install, uninstall, distclean): Added actions for
6799 (.c.x): Use guile-snarf.
6800 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6801 (gen_c_files): Note that these depend on guile-snarf.
6802 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6803 now in "snarf.h". Added #include "snarf.h" to get them.
6804 * libguile.h: Added #include "snarf.h".
6805 (Patches applied and tweaked by Jim Blandy.)
6807 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6809 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6810 standards suggest against providing prototypes for system
6811 functions. Thanks to Greg Troxel.
6813 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6815 * strports.c (scm_eval_0str): New function.
6816 #include "read.h", to get prototype for scm_read.
6817 * Makefile.in (strports.o): Update dependencies.
6818 * strports.h: New prototype.
6820 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6821 scheme name from "int?" to "integer?". It seems to do the job.
6822 * numbers.h: Rename prototype too.
6823 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6826 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6827 scm_num_eq_p): Rename these according to R4RS conventions: call
6828 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6829 to making libguile R4RS compliant without ice-9...
6831 * load.c (scm_sys_search_load_path): Search for files under all
6832 extensions listed in the %load-extensions variable. If FILENAME
6833 is absolute, return it unchanged, without searching the load path.
6834 (scm_loc_load_extensions): New variable, pointing to
6835 %load-extensions' value cell.
6836 (scm_init_load): Initialize it, and the value it points to.
6837 (scm_primitive_load_path): Improve error reporting.
6839 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6840 of new Scheme variable %load-hook.
6841 (scm_primitive_load): Apply %load-hook to filename.
6843 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6845 * configure.in: add tests for figuring out whether buffered data
6846 is available in a FILE structure, which is needed by char-ready.
6848 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6851 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6852 exceptions using misc_error instead of syserror. It seems a bit
6853 odd to throw an exception if a string can't be found in the
6854 environment, but it's consistent with open-file, stat etc.
6855 (simpos.h): remove sys_ from getenv.
6857 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6858 occurs, throw an error instead of returning errno. Return value
6860 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6862 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6864 * filesys.c (scm_stat2scm): derive file type and permissions from
6865 the stat mode and append them to the returned vector.
6866 There isn't much overhead in doing this and it avoids the need to
6867 work with S_IRUSR et al. in Scheme.
6868 Define symbols scm_sym_regular etc.
6869 (scm_init_filesys): don't intern S_IRUSR etc.
6871 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6872 and s_primitive_load_path.
6874 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6876 * error.h: don't declare error symbols. prototype for scm_misc_error.
6878 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6881 * error.c: use SCM_SYMBOL to set up error keys.
6882 scm_misc_error: new procedure.
6884 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6886 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6887 between `#!' and `!#' is ignored.
6888 (skip_scsh_block_comment): New function.
6890 * feature.c (scm_set_program_arguments): New argument, FIRST.
6891 * feature.h: Update prototype.
6892 * init.c (scm_boot_guile_1): Pass new argument to
6893 scm_set_program_arguments.
6895 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6897 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6898 (scm_boot_guile): Call scm_set_program_arguments here, later than
6899 the old initialization.
6901 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6902 initialization procedure.
6903 - Delete in, out, err arguments; there are other perfectly good
6904 ways to override these when desired.
6905 - Delete result argument; this function shouldn't ever return.
6906 - Rename init_func argument to main_func, for less confusion.
6907 - Delete boot_cmd argument; main_func is more general.
6908 -Add 'closure' argument, to help people pass data to main_func
6909 without resorting to global variables.
6910 - Abort if reentered; don't bother returning an error code.
6911 - Call scm_init_standard_ports to set up the default/current
6912 standard ports; no need to pass them to scm_start_stack.
6913 - Remove code to evaluate the boot_cmd, and start the repl; let
6914 the user do something like that in main_func if they want.
6915 - Remove code to package up a return value; main_func can do any
6917 - Call exit (0), instead of returning.
6918 (scm_start_stack): Don't initialize the I/O ports here; that's
6919 weird. Delete in, out, err arguments. Move guts to
6920 scm_init_standard_ports, scm_stdio_to_port.
6921 (scm_init_standard_ports): New function, to set up current and
6922 default standard ports.
6923 (scm_start_stack, scm_restart_stack): Make these static.
6924 * init.h (scm_boot_guile): Adjust declaration.
6925 (scm_start_stack, scm_restart_stack): Remove externally
6926 visible declarations for these.
6927 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6929 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6930 written out several times in scm_start_stack.
6931 * fports.h: New declaration for the above.
6933 * feature.c (scm_set_program_arguments): New function.
6934 * feature.h: New declaration for the above.
6936 * ports.c: Formatting tweak.
6938 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6940 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6941 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6942 for obtaining the address of a car or cdr field. Motivation:
6943 &SCM_CXR make assumptions about the internal structure of the
6946 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6947 Motivation: see SCM_CXRLOC.
6949 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6950 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6951 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6952 Motivation: Safer use. Some other macros are defined in terms of
6953 these operations. If these are defined using the SCM_SETCXR
6954 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6955 to inefficiency and an <e1> with side-effects could potentially
6956 break. Also, these particular operations are heavily utilized in
6957 the garbage collector. In unoptimized code there will be a
6960 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6961 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6962 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
6963 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
6964 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
6965 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6966 vports.c: Cleaned up use of pairs: Don't make any special
6967 assumptions about the internal structure of selectors and
6968 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6969 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
6970 (Among other things, this change makes it easier to build Guile
6971 with certain compilers which have problems with casted lvalues.)
6973 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6975 * stacks.c: Improve selection of relevant stack frames when making
6976 a stack object. Introduce one level of indirection in the stack
6977 object to make it possible to "narrow" to a certain region of the
6978 stack. This facilitates making use of more clever algorithms (not
6979 implemented) for selecting relevant frames and gives a cleaner
6980 design since selection of frames can be done independently of
6981 extraction of frames from the real stack.
6982 (scm_stack_id): Also take #t as argument which means look at
6985 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
6986 Turn n_tail into an integer directly representing current number
6987 of frames in stack. Add field tail.
6989 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
6991 * debug.c (scm_make_memoized): Made it available at scheme level.
6992 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
6993 SCM_NIMP before applying heavier predicates in argument checking.
6994 (scm_local_eval): Also take memoized object as argument.
6996 * backtrace.c (scm_display_error): Just a safety measure: Stacks
6997 aren't created with zero length, but should such a strange
6998 creature suddenly turn up...
7000 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
7002 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
7003 `del', for the sake of C++ compilers. (Patch applied by JimB.)
7005 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
7007 * variable.c (scm_make_variable): Make the name hint optional, as
7009 (anonymous_variable_sym): Renamed from variable_sym. All uses
7012 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
7013 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
7014 of scm_primitive_load_path was also changed to
7015 "primitive-load-path", from "%try-load-path". Callers changed.
7016 We'd like to respect the convention that a function named
7017 "try-mumble" should behave just like the function called "mumble",
7018 but return #f instead of signalling some error.
7019 * load.h: Rename prototypes.
7021 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7023 * print.c (make_print_state, grow_print_state), print.h: Modified
7024 the print state representation: Don't use a tail array for
7025 recording of circular references. Resizing of the print state
7026 structure invalidates the print state pointer. To avoid passing
7027 around an indirect print state reference to all printing
7028 functions, we instead let the print state reference a resizable
7031 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7033 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
7034 Don't crash when passed an improper list terminated by a
7035 non-immediate value.
7037 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
7039 Allocate data for structures on an eight-byte boundary, as
7040 required by the tagging system.
7041 * struct.c (alloc_struct): New function.
7042 (scm_make_struct, scm_make_vtable_vtable): Call it.
7043 * struct.h (scm_struct_n_extra_words): Bump to 3.
7044 (scm_struct_i_ptr): New "field".
7045 * gc.c (scm_gc_sweep): When we need to free the data, use the
7046 information stored by alloc_struct to find the beginning of the
7047 block allocated to the structure, so we can free it.
7049 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7051 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
7054 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
7055 (scm_debug_info): New member: id.
7057 * stacks.c: Stacks are now represented as structs; Stacks have an
7058 id given to them by `start-stack'.
7059 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
7061 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
7062 Changed stack representation.
7064 * debug.c (scm_procedure_name): Try procedure property `name' for
7065 compiled closures aswell.
7067 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
7069 * eval.c: scm_i_name moved to gsubr.c
7070 (scm_m_define): Record names of all kinds of procedure
7071 objects. (Earlier, only closures were recorded.)
7073 * procprop.h: Added declaration of scm_i_name.
7075 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7076 (scm_make_gsubr): Record names of compiled closures.
7078 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7080 * debug.c, debug.h: Removed obsolete code.
7082 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7083 stacks.c: Renamed regs --> scm_contregs.
7085 * print.c (scm_free_print_state): Cleanup print state before
7086 returning it to pool. It is better to do it here than in
7087 scm_prin1 since scm_prin1 is called often.
7089 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7090 s_set_source_property_x): Check that first argument is a pair or a
7093 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7094 scm_i_line, scm_i_column and scm_i_breakpoint global.
7096 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7097 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7100 * debug.h: Added debug object smob declaration and macro
7103 * configure.in: Build with backtrace.o and stacks.o if debug
7106 * Makefile.in: Added entries for new files: backtrace.c,
7107 backtrace.h, stacks.c and stacks.h.
7109 * symbols.c (scm_sym2ovcell): Fixed documentation.
7111 * _scm.h (min, max): Added.
7113 * async.c: Moved `min' macro to _scm.h.
7115 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7116 SCM_BACKTRACE_INDENT.
7118 * eval.c: Added new debug options `maxdepth' and `indent'.
7120 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
7122 * print.h: Added selector SCM_PRINT_STATE.
7124 * print.c: New functions: scm_make_print_state,
7125 scm_free_print_state.
7127 * print.h: Added declarations for scm_make_print_state,
7128 scm_free_print_state.
7130 * debug.c (scm_m_start_stack): New acro.
7132 * debug.h: Small cleanup.
7134 * init.c (scm_boot_guile_1): Moved scm_init_debug below
7137 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

7157 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,

7159 declare functions with prototypes. (Patch thanks to Marius
7162 More prototype-related changes from Marius Vollmer:
7163 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7164 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7165 * ports.h (ptobfuns): Added prototypes. This means some casting in
7167 * fports.c: Added casts for initializations, since the functions
7168 are defined to take FILE * as their stream argument, not SCM.
7169 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7170 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7171 to `char *str_data' to conform to prototype.
7173 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7175 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7177 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7179 * stime.c, stime.h: use SCM_P method.
7181 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7183 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7184 be given at least two arguments. Insist that lst's last element
7185 be a list, but don't make any requirements of its predecessors.
7187 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7189 * eval.c (scm_nconc2last): Revert last change; there seems to be
7190 other stuff going on here.
7192 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7194 * eval.c (scm_nconc2last): Make sure that each element of lst
7195 (which is a list of argument lists, except for the tail) is a
7196 proper list, i.e., finite and terminated by '().
7198 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7200 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7203 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7204 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7207 * vectors.c (scm_make_vector): Fill vectors with the undefined
7208 value, to help make Guile Scheme code more portable to other
7211 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7212 * symbols.h, tags.h: Doc fixes.
7214 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7216 * async.c (scm_take_signal): Doc fixes.
7218 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7220 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7221 want to subtract it from the modulus; we just want to leave it
7224 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7226 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7229 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7231 * throw.c (scm_catch_apply): Finished implementation of
7234 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7236 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7238 (scm_init_filesys): set "i/o-extensions" feature.
7241 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7243 * Makefile.in (root.o): Correct dependencies.
7245 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7247 * Makefile.in: Added dependency entry for root.o.
7249 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
7250 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
7252 * init.c (scm_start_stack): Set initial root continuation number
7255 * procs.c: New function: scm_thunk_p.
7257 * procs.h: Added declarations of scm_thunk_p.
7259 * root.c: Renamed `call-with-new-root' -->
7260 `call-with-dynamic-root'.
7261 (cwdr): Removed allocation of new root state. This should be done
7262 separately by use of scm_make_root.
7263 (scm_apply_with_dynamic_root): New function: Does what it
7264 sounds like. Needed when spawning threads.
7266 * root.h: Added member last_debug_frame to root state.
7267 Added #include "libguile/debug.h"
7269 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
7270 arguments. The motivation is that code in root.c needs catch
7271 functionality, and we want to avoid code duplication.
7272 New functions: scm_catch, scm_lazy_catch. These are wrappers for
7273 scm_catch_apply. scm_lazy_catch is intended to introduce catch
7274 handlers that run without popping the stack into the dynwind
7277 * throw.h: Added prototypes for scm_catch_apply and
7280 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7282 * root.h (scm_root, scm_set_root): Decouple thread support details
7283 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
7284 SCM_SET_THREAD_LOCAL_DATA.
7286 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
7287 and tortoise scanning loop.
7289 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
7291 * Makefile.in: Rebuild dependencies.
7293 * libguile.h: #include "libguile/print.h" before "smob.h", since
7294 the latter uses the print_state structure.
7296 * throw.c (scm_ithrow): Use the correct variable when checking to
7297 see if a given element of scm_dynwinds is a valid catch.
7299 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
7300 structure, abort; don't just silently ignore the garbage.
7302 * _scm.h: #include "print.h" here, since it seems to be used just
7304 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
7305 strports.c, unif.h: Don't #include "print.h".
7307 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7309 * feature.h (scm_loc_features): Removed external declaration.
7310 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
7312 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7314 * feature.c (scm_init_feature): Added threads feature (needs to be
7315 initialized here, since features doesn't exist when
7316 scm_init_threads is called).
7318 * libguile.h: Added #include "libguile/../threads/threads.h".
7319 (This is a kludge to get thread support working. This should be
7322 * configure.in, acconfig.h: Added flags for thread support.
7324 * scmsigs.c: Define `signal' to be `pthread_signal' if using
7327 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
7328 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
7331 * _scm.h: Added conditional #include "threads.h"
7333 * __scm.h (SCM_ASYNC_TICK): Added call to macro
7334 SCM_THREADS_SWITCHING_CODE.
7336 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
7337 allocate the basic dynamic root object.
7338 (scm_boot_guile): Added call to scm_init_root.
7340 * root.c, root.h: Added root smob.
7341 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
7342 functions: Implements dynamic roots mostly according to spec in
7343 SCM manual. Main difference is that the second argument is a
7344 throw handler rather than an error "thunk".
7346 * root.h: Added declaration of scm_init_root.
7348 * root.c: Added #include "genio.h", #include "smob.h", #include
7349 "pairs.h", #include "throw.h", #include "dynwind.h", #include
7351 (scm_init_root): Added #include "root.x".
7353 * throw.c: Added #include "stackchk.h"
7354 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
7355 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
7356 can be used in scm_call_with_new_root; Added reenabling of stack
7357 checking when catching a throw.
7359 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
7361 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
7363 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
7364 element is not found, as per R4RS.
7366 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7368 * list.c: Doc fixes throughout.
7370 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7372 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7373 declare the char * to be const. Avoids a warning in rgx.c.
7375 * ports.h: spelling fix.
7377 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7380 * load.c (scm_sys_try_load_path): throw an error if file not found
7381 (like it says it in NEWS).
7383 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7385 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7386 PROPS slot to '(), not #f; it's an empty alist.
7388 * throw.h, throw.c: Use SCM_P instead of #if hair.
7390 Remove special support for uncaught throws; see throw.c for
7392 * throw.c (uncaught_throw): New function.
7393 (scm_ithrow): Call uncaught_throw if we don't find a throw
7394 target; don't mess with scm_bad_throw_vcell.
7395 (scm_bad_throw_vcell): Variable deleted.
7396 (scm_init_throw): Don't initialize it.
7398 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7401 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7403 * numbers.c (scm_istr2int): If the number is short (as most
7404 numbers are), just call scm_small_istr2int to deal with it.
7405 (scm_small_istr2int): New function, created by un-#ifdefing the
7406 non-bignum version of scm_istr2int and renaming it.
7408 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7410 * load.c (scm_sys_try_load): don't check whether value returned
7411 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7412 Change the Scheme name from %try-load to primitive-load.
7414 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7415 Can avoid passing a message, allowing it to be derived in the
7416 error handler (e.g., if we want to throw to the key both from
7419 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7421 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7422 references now have a new appearance which is more compact and
7423 also gives a clue about what the target of the reference is.
7424 By setting parameters in the print state, more fancy printing can
7425 be achieved. This is used by the (not yet commited) backtrace
7428 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7430 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7433 * print.c: Added #include "struct.h". Removed function
7436 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7437 scm_iprin1. Removed prototype for scm_prlist.
7439 * arbiters.c (prinarb),
7440 async.c (print_async),
7441 debug.c (prindebugobj, prinmemoized),
7442 eval.c (prinprom, prinmacro),
7443 filesys.c (scm_fd_print, scm_dir_print),
7445 mallocs.c (prinmalloc),
7446 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7447 smob.h (scm_smobfuns),
7448 srcprop.c (prinsrcprops),
7450 unif.c, unif.h (scm_raprin1, rapr1),
7451 variable.c (prin_var): Changed argument `int writing' to
7452 `scm_print_state *pstate'.
7454 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7455 that it will be called before scm_init_print.
7457 * print.c (scm_prin1): Print states are now allocated when calling
7458 scm_prin1 and then passed around to all printing functions as an
7459 argument. A cache `print_state_pool' enables reuse of print
7461 (scm_make_print_state): New function.
7462 (scm_iprin1): Adaption to print states.
7463 (scm_iprlist): An initial "hare and tortoise" scan brings down
7464 time complexity to O (depth * N). (Better time complexity will be
7465 achieved when the printing code is completely rewritten.)
7467 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7469 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7470 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7471 it gets done whether or not the cache variable has a value.
7473 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7475 Distinguish #f and ().
7476 * __scm.h: #undef SICP.
7477 * pairs.h (SCM_EOL): Delete this definition, equating it with
7479 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7480 the value it used to have. Doc fixes, too.
7482 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7484 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7485 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7486 Lord's implementation of structs, allowing for tail arrays as
7487 described in the manual. Also fixed some bugs. (Both the interface
7488 and the implementation should be improved.)
7490 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7492 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7493 People who whish to see the source can do `(print-enable 'source)'.
7494 Removed #ifdef DEBUG_EXTENSIONS.
7496 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7498 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7499 integer (assuming for now accepting an integer is a good thing).
7501 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7502 %S will be used instead for write'ing arguments.
7504 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7505 asserts. fix a few other asserts.
7506 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7507 scm_uniform_vector_ref, scm_array_set_x,
7508 scm_dimensions_to_unform_array): change args in
7509 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7510 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7511 scm_substring_fill_x): likewise.
7512 gsubr.c (scm_gsubr_apply): likewise.
7513 eval.c (SCM_APPLY): likewise.
7515 * eval.c (4 places): replace scm_everr with lgh_error or
7518 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7519 scm_memory_error): new procedures.
7520 scm_everr: deleted. can use scm_wta, dropping first two args.
7521 scm_error: convert NULL subr to SCM_BOOL_F.
7523 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7526 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7529 * error.c, error.h: new error keys: scm_arg_type_key,
7530 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7532 scm_wta: reimplement using lgh_error instead of scm_everr.
7534 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7536 * gdbint.c: scm_lread now has one more argument.
7538 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7539 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7540 loading source from non-file ports, which, e. g., happens when
7541 using the Emacs interface).
7543 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7546 * read.c: Added code for recording of positions of source code
7547 expressions; New functions: recsexpr, scm_lreadrecparen;
7548 _scm_make_srcprops --> scm_make_srcprops
7549 (scm_flush_ws): Removed updating of positions counters. This work
7550 is already done by scm_gen_getc
7552 * read.h: Added prototype for scm_lreadrecparen
7554 * print.c: Added #include "alist.h"
7556 * eval.c: Added #include "hash.h"
7558 * eq.c: Added #include "ramap.h"
7560 * options.c: Documentation fixes.
7562 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7563 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7564 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7565 --> scm_make_srcprops
7567 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7568 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7569 function calls in the definition of the whash access macros.
7571 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7573 * init.c (scm_boot_guile): Add level of indirection to
7574 scm_boot_guile_1() to ensure that stack base pointer is properly
7575 initialized. There was no guarantee that variable i was the
7576 highest/lowest variable on stack (i.e. the call frame of
7577 scm_boot_guile was not completely protected from gc).
7579 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7581 * ports.h (scm_port_table): put back file_name, it will be used to
7582 support debugging. Undo related changes in fports.c, ioext.c,
7585 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7587 * ports.h (scm_port_table): remove file_name member for now, it seems
7589 * fports.c (scm_open_file): don't set file_name in PTAB.
7590 (prinfport): don't use file_name in PTAB.
7591 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7592 * ports.c (scm_add_to_port_table): don't intialize file_name.
7593 (scm_port_file_name): remove for now.
7594 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7596 * fports.h (scm_mkfile): prototype deleted.
7597 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7599 * debug.c, unif.c: use scm_out_of_range instead of
7600 wta for range errors (ASSERT still needs work).
7602 * error.c, error.h (scm_out_of_range): new procedure.
7604 * error.c, error.h (scm_out_of_range_key): new key.
7606 * posix.c (scm_sync): #else was missing.
7608 * error.c, error.h: append _key to names scm_num_overflow and
7611 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7612 of consing an empty list.
7613 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7614 of macros, saves code and string space.
7615 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7616 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7617 lower case. Rename scm_syserror_m to scm_syserror_msg.
7618 error.h: prototypes for new procedures.
7620 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7622 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7624 * error.c, error.h: setup scm_num_overflow key.
7626 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7627 Remove definition of SCM_OVSCM_FLOW.
7629 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7631 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7632 explicit message and args.
7634 * error.c, error.h, __scm.h: change system_error_sym to
7637 * error.c (system_error_sym): remove leading %% from the Scheme name
7640 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7642 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7644 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7645 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7646 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7647 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7648 renamed. (These were introduced by unsupervised name
7651 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7653 * print.c: Added code for detection of circular references during
7654 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7655 a hook for printing of closures (accessible via print options).
7656 This leads to a split of calls to scm_iprin1 into two classes:
7657 elementary print operations (e. g. the code which prints a smob)
7658 still use scm_iprin1 while top level calls (like scm_display) use
7659 scm_prin1. scm_prin1 begins by clearing the data structure used
7660 to record reference information.
7662 * print.h: Added declarations of scm_prin1 and scm_prlist.
7664 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7666 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7668 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7670 * error.c (err_head): scm_iprin1 --> scm_prin1
7672 * debug.c: Adjusted header comment.
7676 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7678 * strerror.c: Doc fix.
7680 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7682 * gdbint.c (gdb_read): Now possible to run during GC.
7683 (unmark_port, remark_port): New functions.
7685 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7687 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7688 of allocating a new string object. Also, increase size by
7689 the factor 2 instead of 1.5.
7691 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7693 * __scm.h (SCM_P): Corrected to run under traditional C.
7695 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7698 * async.c: Calls to scm_sysintern corrected.
7700 * async.h (scm_async_clock): Redundant declaration removed.
7702 * continuations.c (scm_dynthrow): Redundant declaration removed.
7704 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7705 Definition typos corrected.
7707 * debug.h: Missing declarations of functions in debug.c added
7710 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7711 Missing declarations to functions in eval.c added.
7713 * filesys.c: Possibly uninitialized variable rv.
7715 * gc.h (scm_object_addr, scm_unhash_name): Missing
7716 declarations of functions defined in gc.c added.
7718 * genio.c: Possible typos str_data -> wstr_data. ???
7720 * genio.c: Possibly unintended shadowing of local variable
7721 `int c' (gotos out of scope of inner `c'). ???
7723 * init.c: Uninitialized `SCM last' may be used.
7725 * ioext.h: (scm_sys_isatty_p): Typo.
7727 * list.h (scm_list_head): Missing prototype for function in
7730 * numbers.c (scm_two_doubles): Changed from extern to static
7731 (is used only within numbers.c).
7733 * numbers.h: Repeated declarations removed.
7735 * ports.h (scm_close_all_ports_except): Declaration for the
7736 function defined in ports.c added.
7738 * posix.h: Missing declarations added.
7740 * procs.h (scm_make_subr_opt): Missing declaration added.
7742 * socket.h (scm_sys_gethost): Missing declaration added.
7744 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7746 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7747 Missing declarations added.
7749 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7751 * struct.c: Uninitialized variable `SCM answer' may be used.
7753 * unif.c (l2ra): Declaration prototype.
7755 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7756 defined in ramap.c).
7758 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7759 Redundant declarations removed (they are in ramap.h).
7761 * variable.h (scm_make_udvariable,
7762 scm_make_undefined_variable): Declaration corrected to
7763 correspond variable.c.
7765 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7766 Missing declarations added.
7768 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7770 * Makefile.in (distclean): Don't forget to delete fd.h.
7772 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7774 * fd.h.in, tags.h: Trivial cleanups.
7776 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7777 marksweep.h just declared functions from gc.c.
7778 * gc.h, libguile.h: Don't #include "marksweep.h".
7779 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7780 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7781 dependencies updated.
7783 * libguile.h: Don't #include "files.h"; it's been deleted.
7785 * files.c (scm_sys_delete_file): Moved to filesys.c.
7786 File is now empty; deleted.
7788 * filesys.c: scm_sys_delete_file is now here. Remove
7789 #if's; they seem to rely on remnants of an old portability
7790 regimen. If the problems come up again, solve them properly,
7791 using autoconf. Specifically: Don't test M_SYSV, and #define
7792 remove to be unlink if it's #defined; don't use remove just
7793 because HAVE_STDC_HEADERS is #defined.
7794 * filesys.h: Add declarations for scm_sys_delete_file.
7795 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7796 files.o, files.h, files.c, and files.x.
7797 * init.c: Don't #include "files.h", and don't call scm_init_files.
7799 Use SCM_P instead of PROTO; the latter intrudes on the user's
7801 * params.h: Deleted; definition of SCM_P moved to...
7802 * __scm.h: ... here, where it replaces PROTO macro.
7803 * libguile.h, smob.h: Don't #include "params.h".
7804 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7805 smob.h: Fix prototypes accordingly.
7806 * Makefile.in: Update dependencies.
7807 (inner_h_files): Remove params.h.
7809 * gc.c: #include "gc.h"; every module should include its header,
7810 to let the compiler cross-check the declarations against the
7813 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7814 simpos.h: #include "libguile/__scm.h".
7816 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7818 * init.c: Don't forget to #include smob.h and init.h.
7819 * Makefile.in: Dependencies updated.
7821 * smob.h: Use PROTO instead of #if __STDC__.
7823 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7825 * __scm.h: Doc fixes.
7827 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7828 <angles>; this allows `make depends' to work properly.
7830 * libguile.h: #include smob.h and pairs.h before the others; they
7831 define typedefs used by other headers.
7833 C files should #include only the header files they need, not
7834 libguile.h (which #includes all the header files); the pointless
7835 recompilation was wasting my time.
7836 * Makefile.in (all .o dependency lists): Regenerated.
7837 * libguile.h: Don't try to get a definition for size_t here...
7838 * __scm.h: Do it here.
7839 * _scm.h: Since this is the internal libguile header, put things
7840 here that all (or a majority) of the libguile files will want.
7841 Don't #include <libguile.h> here; that generates dependencies on
7842 way too much. Instead, get "__scm.h", "error.h", "pairs.h",

7943 * stackchk.h: #include "libguile/debug.h",
7945 * print.h, read.h: #include "options.h", since everyone who uses
7946 either of these files will need that.
7948 * smob.h: #include "ports.h", "genio.h", and "print.h", since
7949 anyone who uses this file will need them to define the smob
7950 printing functions. Also, get markers.h, since people will need
7951 to #define the mark functions.
7953 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
7954 * ports.h: ... to here.
7956 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7957 don't rely on archaic C default type rules.
7959 * fports.h: #include "libguile/ports.h", since you need that in
7960 order to parse this.
7962 * genio.h: #include "libguile/print.h", because you need that to
7963 parse this; don't bother #including "ports.h", since print.h gets
7966 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7968 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7969 this; it's now a reference to an element of *scm_root.
7971 * debug.h: Don't #include "options.h"; the compiler won't be able
7972 to find that once the headers are installed; instead, #include
7973 "libguile/options.h".
7974 * gc.h: Same, with marksweep.h.
7975 * mbstrings.h: Same, with symbols.h.
7976 * scmhob.h: Same, with _scm.h.
7977 * smob.h: Same, with params.h.
7979 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
7980 C files; there's no need for this, and it forces recompilations
7983 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
7985 * error.c (scm_error): declare scm_error_callback.
7987 * error.h: prototype for scm_error_callback.
7989 * __scm.h: define lgh_error.
7990 (SCM_SYSERROR): redefine using lgh_error.
7992 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
7994 * error.c (scm_error): new procedure.
7996 * error.h: prototype for scm_error.
7998 * Makefile.in (install): install scmconfig.h from the current
7999 directory, not $(srcdir).
8001 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8003 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8004 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8005 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

8011 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8012 vports.h, weaks.h: #include "libguile/__scm.h", not
8013 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
8014 dependencies are within libguile properly.
8016 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8018 * Makefile.in (.c.x): Simplify; there's no need to run this rule
8019 when scmconfig.h doesn't exist.
8021 * load.c (scm_sys_try_load): Correct spelling.
8023 * feature.c (scm_loc_features): Make this static.
8025 * Makefile.in (libpath.h): Omit trailing slash from path. We
8026 shouldn't require it of users, so why put it here?
8028 Move code to initialize and search %load-path from ice-9 to C
8029 code, so we can use the load-path to find the ice-9 boot code;
8030 this makes it easier to run Guile without installing it. See
8031 corresponding changes in guile/Makefile.in.
8032 * feature.c: Move stuff concerned with the load path to load.c.
8033 (scm_compiled_library_path): Deleted.
8034 Don't #include libpath.h here.
8035 * feature.h: Don't mention scm_compiled_library_path.
8036 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
8037 <sys/stat.h>, and <unistd.h> (if present).
8038 (R_OK): #define if the system hasn't deigned to.
8039 (scm_loc_load_path): New variable.
8040 (scm_init_load_path, scm_sys_search_load_path,
8041 scm_sys_try_load_path): New functions.
8042 (scm_init_load): Initialize scm_loc_load_path to point to the
8043 value cell of the Scheme %load-path variable.
8044 * load.h: Add declarations for scm_sys_search_load_path,
8045 scm_sys_try_load_path.
8046 * init.c: Call scm_init_load_path.
8047 * Makefile.in (feature.o, load.o): Dependencies updated.
8049 * load.c, load.h: Rewrite using PROTO macro.
8051 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8053 * gc.c (scm_cellp): New function: C predicate to determine if an
8054 SCM value can be regarded as a pointer to a cell on the heap.
8056 * gc.h: Added declaration of scm_cellp.
8058 * gdb_interface.h: New file: The GDB interface header from the GDB
8061 * gdbint.c: New file: GDB interface.
8063 * gdbint.h: New file: GDB interface.
8065 * libguile.h: Added #include <libguile/gdbint.h>.
8067 * init.c (scm_boot_guile): Added scm_init_gdbint.
8069 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
8070 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
8071 found if object files and source are kept separate).
8073 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8075 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8077 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8079 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8080 TK_SRC_DIR; they're not relevant any more.
8082 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8083 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8085 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8087 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8088 search path, so we can find the <libguile/MUMBLE.h> headers.
8090 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8092 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8093 implicit in the .c.o rule.
8094 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8097 Put the library path in a header file, instead of passing it on
8098 the command line in every compilation.
8099 * Makefile.in (libpath.h): New target.
8100 (feature.o): Depend on libpath.h.
8101 (clean): Delete libpath.h.
8102 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8103 * feature.c: ... #include "libpath.h" here.
8104 * .cvsignore: Ignore libpath.h.
8106 Don't install the unwashed masses of Guile header files in the
8107 main #include path; put most of them in a subdirectory called
8108 'libguile'. This avoids naming conflicts between Guile header
8109 files and system header files (of which there were a few).
8110 * Makefile.in (pkgincludedir): Deleted.
8111 (innerincludedir): New variable; this and $(includedir) are enough.
8112 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8113 (installed_h_files): Divide this up. Now this variable lists
8114 those header files which should go into $(includedir) (i.e. appear
8115 directly in the #include path), and ...
8116 (inner_h_files): ... this new variable says which files appear in
8117 a subdirectory, and are referred to as <libguile/mumble.h>.
8118 (h_files): List them both.
8119 (install): Create innerincludedir, not pkgincludedir. Put
8120 the installed_h_files and inner_h_files in their proper places.
8121 (uninstall): Corresponding changes.
8122 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8123 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8124 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
8125 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,

8128 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8129 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8130 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8131 vports.h, weaks.h: Find __scm.h in its new location.
8132 * __scm.h: Find scmconfig.h and tags.h in their new locations
8133 (they're both "inner" files).
8135 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8137 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8139 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8141 * posix.c: Doc fixes.
8143 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8145 * socket.c: Don't include a prototype for inet_aton; just use a
8146 K&R style declaration, to avoid warnings but minimize the chance
8147 of conflicts with the system.
8149 On NextStep, <utime.h> doesn't define struct utime, unless we
8150 #define _POSIX_SOURCE before #including it.
8151 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8152 * acconfig.h: New comment text for above CPP symbol.
8153 * configure.in: Call it.
8154 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8156 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8158 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8159 testing for __EMX__.
8161 * posix.c: #include <libc.h>, if it exists.
8163 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8164 don't even know if the latter exists.
8166 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8167 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8168 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8170 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8172 (scm_init_posix): Use them when initializing the Scheme constants
8175 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8177 * Makefile.in (libdir, includedir, bindir): Use the
8178 autoconf-supplied values, instead of deriving them ourselves.
8179 (pkgincludedir, datadir, pkgdatadir): New variables.
8180 (install, uninstall): Put the header files in a special
8181 subdirectory, not in the main search path.
8183 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8184 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8186 * Makefile.in (IMPLPATH): Deleted; never used.
8188 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8189 on the Tcl/Tk source any more.
8190 (INCLUDE_CFLAGS): Remove references to the above.
8192 * Makefile.in (version.o): Corrected dependencies.
8194 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8196 * libguile.h: #include "version.h"
8198 * init.c (scm_boot_guile): Call scm_init_version.
8199 * gscm.c (gscm_run_scm): Call scm_init_version.
8201 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8202 GUILE_VERSION): AC_DEFINE these.
8203 (acconfig.h): #undef the above symbols.
8205 * Makefile.in (libobjs): Add version.o.
8206 (installed_h_files): Add version.h.
8207 (c_files): Add version.c.
8208 (gen_c_files): Add version.x.
8209 (version.o): New rule.
8210 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8211 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

8220 weaks.o): Add version.h to dependency lists.
8221 (markers.o): Remove duplicate rule.
8223 * version.h: New file.
8225 * version.c: New file.
8227 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8229 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8230 array; use it appropriately. Since GCC is quite happy to
8231 subscript functions, it never warned us about this; we should use
8232 -Wpointer-arith in the future. I guess we never tested
8235 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8237 * socket.c: Doc and copyright fixes.
8239 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8241 * debug.c: Fixed and improved gdb support.
8243 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8245 * socket.c: Added declaration of inet_aton to avoid compiler
8246 warning. (Hope this solution is correct.)
8248 * stime.c: Added declaration of ftime. (This is missing in
8251 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
8253 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8255 * Makefile.in (c_files): add strerror.c.
8257 * strerror.c: new file from Emacs' sysdep.c.
8258 maybe configure should also check for sys_errlist.
8260 * configure.in (AC_REPLACE_FUNCS): add strerror.
8262 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8264 * debug.c (scm_init_debug): Added initialization for
8265 scm_evaluator_traps.
8267 * debug.h, debug.c: Various name changes.
8268 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
8269 "debug-options-interface". See commentary in options.c.
8271 * options.h, options.c: Options now have documentation strings.
8272 Also added a long explanatory commentary.
8274 * eval.c, print.h, print.c, read.h, read.c: Modifications to
8277 * gscm.c, init.c, root.c, throw.c: Bug fixes:
8278 last_debug_info_frame is now updated in all cases.
8280 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
8283 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8285 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
8286 Added option STACK_CHECKING.
8288 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8290 * Makefile.in: Added {debug,options,srcprop}.{h,c}
8292 * __scm.h: Removed symbols for debugging support.
8294 * acconfig.h: Added symbols for debugging support.
8296 * configure.in: Added user option for debugging support.
8297 --enable-debug will include the debugging code into libguile.a.
8299 * continuations.c (scm_make_cont): Enlarged the #if 0 around
8300 scm_relocate_chunk_to_heap.
8302 * debug.c: New file: low-level debugging support. It also
8303 includes support for debugging with gdb. (The extensions to gdb
8304 are written by Per Bothner at Cygnus.)
8306 * debug.h: New file: low-level debugging support.
8308 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
8309 argument pairs. Extensive modifications to the debugging
8310 evaluator. Added "SECTION:" commentaries to clarify what happens
8311 when, during double compilation. Renamed EVALIMP --> EVALIM.
8312 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
8313 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
8314 the beginning of the file. New procedure: scm_unmemocopy.
8315 Added some global state variables needed by the debugging
8316 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
8317 check_entry, check_apply, check_exit, debug_options and
8318 evaluator_traps. New acro: undefine.
8320 * eval.h: Renamed EVAL --> XEVAL.
8322 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
8323 --> scm_make_weak_key_hash_table.
8325 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
8326 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
8328 * libguile.h: Conditionally include debug.h
8330 * objprop.c (scm_object_properties, scm_set_object_properties_x):
8331 scm_object_properties shouldn't return handle. `handle' now gets
8332 initialized in scm_set_object_properties_x. scm_object_properties
8333 doesn't any longer create an entry in scm_object_whash.
8335 * options.c: New file: handling of run time options.
8337 * options.h: New file: handling of run time options.
8339 * posix.c (scm_getpgrp): Cast pointer to getpgrp.

8360 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8362 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
8364 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8366 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8367 and should be called by the final client.
8369 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8371 * gc.h: Use the PROTO macro when declaring functions.
8372 * gc.c: Use the PROTO macro when declaring static functions.
8373 Remove the CPP hair around function definitions.
8375 * gc.c (scm_init_storage): Initialize scm_asyncs.
8377 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8378 preprocessor symbol; "__scm.h" is where it might get #defined.
8379 * __scm.h: Similar: #include <scmconfig.h> before testing
8382 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8384 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8386 * init.c (scm_boot_guile): Add init_func argument; call
8387 (*init_func) instead of calling scm_appinit; it's ucky to
8388 hard-code names for the user's procedures.
8389 * init.h (scm_boot_guile): Adjust declaration.
8391 * __scm.h (PROTO): New macro, for declaring functions with
8394 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8395 eliminate all the __STDC__ conditionals.
8396 (scm_boot_guile): Add declaration.
8397 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8398 Remove __STDC__ conditionals around function definitions; the
8399 declarations in init.h will provide the same information, more
8402 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8403 complain about it in the error message; the error message is
8404 adequate without that note, and there's nothing the user can do
8407 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8409 * Makefile.in (ancillary): Drop def.sed.
8411 * posix.c (scm_init_posix): Use numeric values, rather than
8412 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8413 F_OK. The symbols aren't available on some systems, and I'm
8414 pretty sure their values are fixed by common widespread practice.
8415 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8417 More functions unavailable on some systems.
8418 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8419 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8421 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8422 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8423 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8424 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8425 stub that signals an error as the #else.
8427 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8429 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8431 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8433 * unif.c: include ramap.h.
8435 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8437 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8439 * ports.c: include sys/ioctl.h.
8441 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8443 * configure.in: check for sys/ioctl.h.
8445 * ports.c: include <malloc.h> not "malloc.h".
8447 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8449 * fports.c: remove ttyname and tmpnam declarations.
8451 * posix.c: fewer ttyname declarations.
8453 * fports.c: include <string.h> not "string.h".
8455 * init.c, ioext.c: include string.h and unistd.h.
8457 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8459 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8460 genio.c, simpos.c, vports.c: include string.h.
8462 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8464 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8466 (scm_addr_buffer_size): change type from scm_sizet to int.
8467 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8468 from scm_sizet to int.
8470 * error.c: include unistd.h.
8472 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8475 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8477 * __scm.hd, def.sed: deleted.
8479 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8481 Changes for NeXT, suggested by Robert Brown.
8482 * configure.in: Call AC_TYPE_MODE_T.
8483 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8484 NeXT. Put header file list in alphabetical order.
8485 * configure, scmconfig.h.in: Regenerated.
8486 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8488 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8491 * acconfig.h: New file, providing documentation for the CPP
8492 symbols defined in configure.in
8493 * acconfig-1.5.h: Removed; superceded by the above.
8495 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8497 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8499 * fports.c (scm_open_file): don't return #f, throw error.
8501 * ioext.c (fileno): renamed from %fileno.
8502 (soft-fileno): deleted.
8504 * ports.c (scm_port_revealed): don't need to check for -1 from
8506 (scm_set_port_revealed_x): return unspecified, not #f.
8508 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8510 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8512 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8514 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8516 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8518 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8519 This is necessary on Ultrix, and doesn't hurt portability.
8521 * Makefile.in (dist-dir): New target, implementing a new dist system.
8522 (installed_h_files): Put in alphabetical order.
8523 Remove duplicate entries for markers.h and unif.h.
8524 (c_files): Remove duplicate entries for markers.c.
8525 (ancillary): Renamed from anillery; all uses changed. Remove
8526 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8527 Remove all the ../doc/* files; doc/Makefile.in handles that.
8529 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8531 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8532 every if must have an else, or else the whole command has a
8533 non-zero exit code whenever the if's condition is false.
8535 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8537 * posix.c: include string.h.
8539 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8541 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8544 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8545 Remove leading % from scheme names.
8546 Do not return error values, call SCM_SYSERROR or similar.
8548 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8550 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8552 * struct.c (scm_init_struct): new file.
8554 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8556 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8557 (scm_list_head): added list-head for rapidly chopping argument
8558 lists off of longer lists (and similar).

8563 handle for obj, not the handle itself.
8565 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8567 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8568 weak hash tables last of all marking to avoid an obscure gc bug.
8569 WARNING: circular lists stored in a weak hash table will hose us.
8571 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8573 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8574 new functions similar to scm_substring_move_left_x and
8575 scm_substring_move_right_x.
8577 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8579 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
8582 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
8584 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8586 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8588 * strports.c (scm_strprint_obj): convenience function. C for
8589 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8591 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8592 removed to a separate library
8594 * init.c (scm_boot_guile): copied from guile-tcl.c.
8595 Initialization specific to tcl interpreters removed.
8597 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8599 * ports.c (scm_ports_prehistory): size malloced here doesn't
8600 matter so long as it is non-0 (got rid of "* 4").
8602 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8604 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8605 since its definition was bogus).
8607 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8609 * mallocs.[ch]: back again (for rx at least).
8611 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8613 * ports.c: removed functions relating to the mapping between ports
8614 and descriptors. (That stuff is unix-specific and should be collected
8615 in a separate library).
8617 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
8618 (Tom Mckay@avanticorp.com)
8620 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
8622 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8623 handled correctly (SCM_FREEP was applied to them) -- test for
8624 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
8625 being overwritten with #f. (brown@grettir.bibliotech.com)
8627 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>

8657 NOTE: don't use a alist here.
8658 (scm_set_procedure_properties_x): fix type checking throughout this file.
8660 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
8662 * ports.c (scm_remove_from_port_table): adjust scm_mallocated

8668 * vports.c (scm_make_soft_port): allocate a port table entry
8669 (possibly triggering gc) before setting the tag of the corresponding
8672 * pairs.c (scm_delq_x): never throw an error.
8674 * vectors.c (scm_make_vector): made the default vector fill argument
8675 into '() (much more useful than the previous value, "#unspecified")
8677 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
8679 * ports.c (scm_add_to_port_table): Added fields
8680 to port table entries: file_name, line_num, col.
8681 Update these in open_file, gen_getc and gen_ungetc.
8682 Added procedures to access those fields.
8684 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>
8686 * procs.c (scm_make_subr_opt): new entry point for making
8689 Sat Feb 24 17:11:31 1996 Tom Lord <lord@beehive>
8691 * gc.h: SCM_STACK_GROWS_UP is now set by autoconf.
8693 Fri Feb 23 10:26:29 1996 Tom Lord <lord@beehive>
8695 * numbers.c (scm_exact_p): This function no longer
8696 implements "integer?".
8698 Thu Feb 22 20:56:16 1996 Tom Lord <lord@beehive>
8700 * gc.c (scm_gc_end): simulate a signal at the end of each GC.
8701 (scm_gc_stats): return an assoc of useful data. Replaces "room"
8702 and the stats reporting formerlly built into repl.
8704 * repl.[ch]: removed.
8705 GC statistics keeping moved to gc.c.
8706 Other statistics keeping can be done from Scheme.
8707 REPLS are now written in Scheme.

8718 * feature.c (scm_compiled_library_path): moved here from repl.c.
8719 This file is for stuff relating specifically to Scheme libraries
8722 * eval.c (scm_m_define): don't give warning about redefinition, don't
8725 NOTE: this should throw a resumable exception with parameters --
8726 the name, the top-level env, the variable, the definition, #t/#f: redefining builtin?
8728 * repl.c (scm_gc_begin/end): don't print a message, don't check verbosity.

8746 * gsubr.c (scm_make_gsubr): use exit, not scm_quit. still wrong,
8749 * strports.c: don't reveal the port's string to the caller
8750 because it changes size.
8752 (stputc stwrite): check/change the strings length with interrupts
8755 * objprop.c (scm_set_object_property_x &c): use the generic
8756 hashing functions and be threadsafe.

8759 (per suggestion jaffer@gnu.ai.mit.edu).
8761 * mbstrings.c (scm_multi_byte_string): guard against argument list
8764 * strings.c (scm_make_string): loop cleanup

8792 initialization to fix a race condition.
8794 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

8818 set the multi_byte flag correctly in symbols. This is wrong.
8819 intern_obbary_soft and msymbolize should take an extra parameter.
8820 Also, weird multibyte symbols don't print correctly.
8821 The weird symbol syntax is also a bit bogus (emacs doesn't quite
