1 1999-09-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3 * numbers.c (scm_max, scm_min, scm_sum, scm_difference,
4 scm_product, scm_divide): Bugfix: Don't pass SCM_UNDEFINED to the
5 generic function if the asubr is called with only one arg.
7 1999-09-20 Gary Houston <ghouston@freewire.co.uk>
9 * scmsigs.c (scm_sigaction): add SA_RESTART to flags only if
10 HAVE_RESTARTABLE_SYSCALLS.
11 (scm_init_scmsigs): use siginterrupt if it's available. not
12 everyone who has restartable syscalls has SA_RESTART it seems.
14 (scm_sigaction): use scm_num2long/scm_long2num when converting
15 SIG_DFL/SIG_IGN, in case it doesn't fit in an INUM. use
16 scm_integer_p to test the type.
18 1999-09-18 Gary Houston <ghouston@freewire.co.uk>
20 * _scm.h, scmsigs.c: replace HAVE_RESTARTS with
21 HAVE_RESTARTABLE_SYSCALLS.
23 * strports.c (scm_strport_to_string): create the string from
24 pt->read_buf instead of an expression that evaluates to the
27 * gdbint.c (gdb_print): don't just use SCM_CHARS to get a C string
28 from the port: the port's buffer may not be NUL terminated.
30 1999-09-16 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
32 * Makefile.am (.c.x): Added missing semicolon after `false'.
34 1999-09-15 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
36 * print.c (scm_iprin1): Turn `write' and `display' into
37 primitive generics and use their associated generic functions in
38 scm_iprin1 for GOOPS objects.
40 * backtrace.c: #include <unistd.h> if present.
42 1999-09-14 Jim Blandy <jimb@savonarola.red-bean.com>
44 * Makefile.am (.c.x): Don't create a subshell just to delete the
45 .x file and return false.
46 * Makefile.in: Regenerated.
48 1999-09-13 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
50 * feature.c (scm_create_hook): New function. Replaces
51 scm_make_named_hook which is now deprecated.
52 (scm_make_hook_with_name): New primitive.
53 (print_hook): Hooks now print in a fancy way.
55 1999-09-12 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
57 * __scm.h, backtrace.c, backtrace.h, debug.c, debug.h, dynl-dld.c,
58 dynwind.c, dynwind.h, eval.h, evalext.c, evalext.h, feature.c,
59 feature.h, hashtab.c, hashtab.h, objects.c, objects.h, print.c,
60 procs.c, procs.h, smob.c, smob.h, srcprop.c, strorder.c, struct.c,
61 struct.h: Updated copyright notices.
63 * srcprop.c (scm_source_property): Bugfix: Use SCM_NECONSP instead
64 of SCM_NCONSP. (Thanks to Greg Badros.)
66 * gsubr.c (scm_make_gsubr): Use scm_make_subr_opt for creation of
69 * eval.c, debug.h (SCM_BACKTRACE_WIDTH): New debug option: width.
71 * backtrace.c: Keep backtraces within specified width by
72 adaptively adjusting fancy printing parameters and cut output if
74 (scm_display_application): Check args.
76 1999-09-11 Jim Blandy <jimb@savonarola.red-bean.com>
78 Change the name of the objects returned by OPENDIR from
79 "directory" to "directory stream". A predicate named "directory?"
81 * filesys.c (scm_directory_stream_p): Renamed from scm_directory_p.
82 At the Scheme level, "directory?" -> "directory-stream?".
83 (scm_dir_print): Use the phrase "directory stream" in printed form.
84 * filesys.h (scm_directory_stream_p): Prototype renamed
87 * Makefile.am (CLEANFILES): Remove versiondat.h; that should only
88 be removed by `make distclean', since it's generated by configure.
89 * Makefile.in: Regenerated.
90 (Thanks to Robert Bihlmeyer.)
92 * strop.c (scm_substring_move_x): Signal an error if start1
93 doesn't come before end1. (Thanks to Karoly Lorentey).
95 * numbers.c (scm_istr2flo): Don't call SCM_INEXP without first
96 calling SCM_NIMP. (Thanks to Karoly Lorentey).
98 * version.c (scm_libguile_config_stamp): Deleted. See
99 corresponding change to ../ice-9/boot-9.scm.
100 * versiondat.h.in: Remove definition for GUILE_STAMP.
101 * version.h: Delete prototype.
102 * Makefile.in: Regenerated.
104 1999-09-11 Gary Houston <ghouston@easynet.co.uk>
106 * filesys.c (scm_directory_p): new procedure "directory?" Returns
107 a boolean indicating whether its argument is a directory
108 port as returned by opendir (thanks to Dirk Herrmann for the
111 1999-09-11 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
113 * backtrace.c (display_frame_expr): Don't print a newline.
114 (display_frame): Print the newline here instead.
115 (display_backtrace_body): Don't print "Backtrace:".
116 (scm_backtrace): Print "Backtrace:" here instead.
118 1999-09-09 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
120 * procs.c (scm_setter): Signal WTA if handed an entity or operator
123 * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New
124 primitives. (Thanks to Greg Badros);
125 (scm_hook_to_list): New primitive; Hooks are now smobs.
127 1999-09-08 Gary Houston <ghouston@easynet.co.uk>
129 * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value
130 of #f for the 10th vector element to avoid an exception
131 seen by Bernard Urban.
132 (scm_mktime): unneeded ASSERT removed.
134 1999-09-07 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
136 * eval.c (scm_map, scm_for_each): Converted to dispatch on generic
139 * __scm.h (SCM_WTA_DISPATCH_n, SCM_GASSERTn): New macros.
141 1999-09-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
143 * numbers.c: Converted comparison operations to dispatch on
144 generic if args don't match.
146 * Makefile.am (ETAGS_ARGS): Added support for GPROC and GPROC1.
148 1999-09-06 James Blandy <jimb@mule.m17n.org>
150 * guile-snarf.c: Deleted. Snarfing should respect CPP
151 conditionals, so it needs to actually run CPP. Bleah.
153 1999-09-05 James Blandy <jimb@mule.m17n.org>
155 Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.)
156 * guile-snarf.in: Be sure to exit with an error if CPP does.
157 * Makefile.am (.c.x): Delete the .x file and exit with an error
158 status if guile-snarf exits with an error status.
159 * Makefile.in: Regenerated.
161 * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not
162 scm_makekey, which doesn't exist any more. Guess nobody's using
165 * guile-snarf.c: New implementation of guile-snarf, meant to be
166 more robust than the shell script. I think it's complete, but I
167 haven't tested it at all, and I haven't changed the build process
168 to actually use it. We should compare its output against that of
169 the existing shell script, for all source files.
171 * guile-snarf.c (parse_args): Abort if we haven't handled some
174 1999-09-03 James Blandy <jimb@mule.m17n.org>
176 * load.c (scm_search_path): If the filename has any extension at
177 all, ignore the entire list of extensions. Also, don't check whether
178 the file is accessible. If the file exists, accessible or not, we
179 should return it. Inaccessible files should cause an error later.
180 (Thanks to Keisuke Nishida for the suggestions.)
182 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
184 * gc.c (cleanup, scm_init_storage): Use on_exit if present and
185 atexit not available. (sunos4.1.4 needs it.)
187 1999-09-01 James Blandy <jimb@mule.m17n.org>
189 I take it all back --- bcopy does handle overlapping source and
190 destination areas correctly. At least on every system I could
191 find. But it is better to use AC_REPLACE_FUNCS than to introduce
192 new CPP conditionals.
193 * memmove.c: New file, implementing memmove in terms of bcopy.
194 * scmconfig.h.in: Regenerated.
196 Allocators should use the `void *' type for generic pointers.
197 * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change
198 argument and return types.
199 * gc.h: Corresponding changes to prototypes.
202 1999-08-31 James Blandy <jimb@mule.m17n.org>
204 * numbers.c (scm_init_numbers): Claim to support the `complex'
205 feature, as expected by (ice-9 format). (Thanks to Ceri Storey.)
207 * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can
208 find (ice-9 boot-9) when Guile was compiled in a separate
209 directory from the source. (Thanks to Rodney Brown.)
210 * Makefile.in: Regenerated.
212 * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply
213 table lengths by the size of a single element when growing the
214 table. (Thanks to Bill Schottstaedt.)
216 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
218 * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the
219 SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod
220 since that cuts down the time for type dispatch by 50%.
222 1999-08-30 James Blandy <jimb@mule.m17n.org>
224 * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is
225 not a correct substitute for memmove, because it doesn't handle
226 overlapping source and destination areas on many platforms.
227 Overlaps are the primary reason to use memmove in the first place.
228 * ports.c (scm_ungetc): Same.
229 * strop.c (scm_substring_move_x): Same.
231 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
233 * gc.c (scm_init_storage): Skip registration of cleanup on systems
234 which lack atexit. (Is it important that cleanup is made
235 properly? Maybe we should replace all `exit' with `scm_exit' and
238 * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light,
239 scm_struct_free_standard, scm_struct_free_entity): Declared to
240 return scm_sizet instead of size_t.
242 * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined
243 there on sunos4.1.4.)
245 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
247 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
248 Account for the case when second argument is unbound.
250 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
251 (Thanks to Karoly Lorentey.)
253 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
254 isn't present. (Thanks to Suzuki Toshiya.)
256 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
259 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
262 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
263 Bernard Urban and Ian Grant.)
265 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
266 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
267 change in the representation of entities and operators.)
269 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
271 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
272 don't allocate zero bytes (thanks to Bill Schottstaedt).
274 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
276 * procs.c (scm_setter): Converted to use generic dispatch.
278 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
281 * load.c (scm_search_path): Don't try extensions which already are
282 present at the end of the filename.
283 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
285 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
287 Cleanup and simplification of generic method dispatch.
288 Also, the quadruple representation of entity and operator
289 procedures has been replaced with single.
291 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
293 * print.c (scm_isymnames): Removed #@hash-dispatch.
295 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
296 from eval.c; Support 0 arity methods.
297 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
298 (scm_apply_generic_env): Removed.
299 Replaced slots proc0-3 with procedure.
301 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
302 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
303 SCM_OPERATOR_PROCEDURE.
304 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
305 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
307 * struct.c, struct.h: Replace 4 procedure slots with one.
308 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
310 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
313 * eval.c (scm_sym_args): Removed.
314 (SCM_CEVAL): Simplified entity application.
315 Moved dispatch code to objects.c.
317 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
319 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
321 * sort.c (closureless): Use scm_eval_body.
323 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
324 with a symbol as last form was first called normally and then via
325 `map' or some other mechanism using primitive apply, an ILOC was
328 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
330 This change extends the representation of primitive procedures
331 with more data fields, e.g. a place for documentation and true
332 procedure properties.
334 * procs.c, procs.h (scm_subr_entry): New type: Stores data
335 associated with subrs.
336 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
337 SCM_SUBR_DOC): New macros.
338 (scm_subr_table): New variable.
339 (scm_mark_subr_table): New function.
341 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
343 * gc.c (scm_gc_mark): Don't mark subr names here.
344 (scm_igc): Call scm_mark_subr_table.
347 This change implements a scheme for letting a generic work as a
348 shadow for a primitive procedure. If the primitive procedure
349 can't dispatch on its arguments, control is left over to the
350 generic. Normal wrong type arg errors will be generated until the
351 user has hung the first method on the primitive.
353 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
355 * procs.c, procs.h (scm_subr_p): New function (used internally).
357 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
359 * objects.c, objects.h (scm_primitive_generic): New class.
361 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
363 * print.c (scm_iprin1): Print primitive-generics.
365 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
366 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
368 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
369 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
370 primitives). NOTE: This means that it is now *required* to use
371 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
372 obscured representation that will be removed in the future anyway,
373 so backward compatibility is no problem here).
375 * numbers.c: Converted most numeric primitives (all but bit
376 comparison operations and bit operations) to dispatch on generic
380 Better support for applying generic functions.
382 * eval.c, eval.h (scm_eval_body): New function.
384 * objects.c (scm_call_generic_0, scm_call_generic_1,
385 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
389 Optimization of the generic function dispatch mechanism.
391 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
392 called scm_memoize_method instead of doing a second lookup.
394 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
399 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
400 scm_sysintern so that the binding connected with the subr name
401 isn't cleared when we give set = 0.
404 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
406 More transparent handling of ports with print states.
408 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
409 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
410 instead of a pair of a port and a print state. We'll need to cons
411 once extra in scm_printer_apply but the type system will be
412 cleaner, it will mix better with GOOPS, and, it will be even more
413 transparent to the user.
415 * print.c (scm_get_print_state): New procedure: Given an output
416 port, return the print state associated to it in the current print
417 chain, if one exists;
418 (scm_port_with_print_state): New procedure: Associate a
419 print-state with a port.
420 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
421 (scm_printer_apply): Wrap port and pstate as a smob;
422 (print_state_printer): Removed.
424 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
426 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
429 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
430 testing (otherwise the port-print-state trick won't be transparent
431 to the user; one example where this caused problems was in the
432 (ice-9 format) module).
434 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
436 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
437 SCM_UNSPECIFIED instead of the set value.
439 1999-08-20 James Blandy <jimb@mule.m17n.org>
441 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
443 * ports.h (enum scm_port_rw_active): New enum, containing
444 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
445 zero). The debugger knows about enums, but doesn't know about
447 (typedef scm_port): Declare rw_active member to be an enum
449 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
451 * ports.c (scm_add_to_port_table): Same.
452 * strports.c (st_flush, st_end_input): Same.
454 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
455 scm_must_realloc, and scm_done_malloc as appropriate.
457 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
459 * sort.c (quicksort): Added condition to protect the algorithm
460 from crashing the interpreter if the less predicate is buggy.
462 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
464 * fports.c (fport_write): fix line-buffering mode again.
465 (scm_open_file): recognise 'l' for line-buffering.
466 (scm_setvbuf): recognise _IOLBF for line-buffering.
468 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
470 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
473 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
476 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
478 * fports.c (fport_write): use memcpy instead of strncpy, in case
479 the data contains NUL.
481 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
483 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
485 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
486 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
487 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
488 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
489 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
490 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
491 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
492 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
493 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
494 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
495 scm_sym_ as prefix for symbols.
497 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
499 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
500 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
501 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
502 scm_sym_atcall_cc): Made global.
504 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
506 * eval.c (scm_sym_args): Made global.
508 * objects.c (scm_set_object_procedure_x): Disallow setting of
509 procedures for pure generic functions.
511 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
513 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
514 Scheme name from lseek to seek, but lseek was added recently so
515 it shouldn't be a big problem.
516 * ports.c, gdbint.c, ioext.c: changed callers.
518 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
520 * fports.c (fport_input_waiting): if select is used, return 1
521 instead of whatever FD_ISSET expands to. maybe it will be useful
522 to interpret the value from the input_waiting ptob procedure as a
523 lower bound on the number of bytes available.
525 * Mikael asked for a few names to be changed...
527 * ports.c (scm_make_port_type): take the write procedure as the
528 second argument instead of the flush procedure.
529 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
530 fflush -> flush, read_flush -> end_input, fclose -> close,
531 fill_buffer -> fill_input, ftruncate -> truncate,
532 input_waiting_p -> input_waiting.
534 * ports.c (end_input_void_port): was read_flush_void_port.
535 (scm_set_port_end_input): was scm_set_port_flush_input.
536 (scm_set_port_flush): was scm_set_port_write.
537 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
538 (scm_end_input): was scm_read_flush.
539 (scm_fill_input): was scm_fill_buffer.
540 (scm_flush): was scm_fflush.
541 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
542 (fport_end_input): was local_read_flush.
543 (fport_flush): was local_fflush.
544 (fport_close): was local_fclose.

558 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
560 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
561 forms now contain the expressions to be dispatched upon instead of
562 depending on a surrounding lambda or let; Generic function
563 dispatch has been optimized; `apply' on a generic function now
564 works a little bit strangely. It uses a trick so that the type
565 dispatch code in SCM_CEVAL can be reused.
567 * objects.h, objects.c (scm_apply_generic_env): Added (used by
569 (scm_operator_p): Added.
570 (scm_sym_atdispatch): Added.
571 (scm_set_object_procedure_x): Modified to handle the new style

575 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
577 * eval.c, eval.h (scm_sym_args): Added.
579 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
581 * feature.c, feature.h (scm_c_run_hook): Added.
583 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
584 cdrxnoap and loopnoap instead of begin and loop.
586 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
588 * ports.c (scm_putc, scm_puts),
589 * unif.c (scm_uniform_array_write): use scm_lfwrite.
590 * ports.c (scm_putc): change type of first argument from int to char.
592 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
594 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
595 SCM_IM_HASH_DISPATCH.
597 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
598 (scm_si_redfined, scm_si_hashsets): Moved.
600 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
601 flag which combines type and status info so that the class
602 redefinition protocol has zero cost during normal execution.
604 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
606 * ports.h (scm_ptob_descriptor): include a write procedure again.
607 it's more efficient for unbuffered fports (e.g., sockets.)
609 * ports.c (scm_puts): use ptob->write.
610 * vports.c (scm_make_sfptob): set write proc in ptob.
611 * strports.c (scm_make_stptob): set write proc in ptob.
612 * ports.c (write_void_port): new procedure.
613 * vports.c (sf_write): new procedure.
614 * ports.c (scm_lfwrite): use ptob->write.
615 * strports.c (st_write): new procedure.
616 * fports.c (fport_write): new procedure.
617 (scm_make_fptob): set write in ptob to fport_write.
618 * ports.h: prototype for scm_set_port_write.
619 * ports.c (scm_make_port_type): initialise ptob write procedure.
620 (scm_set_port_write): new proc.
622 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
624 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
625 until we've verified that it is actually a port. (Thanks to
628 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
630 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
631 code, particularly an unnecessary test (len != size, where len ==
632 size). (Was this leftovers from debugging code, or have I missed
635 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
636 size. (Thanks to James Dean Palmer.)
638 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
639 (Thanks to Lorentey Karoly.)
641 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
643 * eval.c (scm_m_expand_body): Use scm_cons_source.
645 * struct.c (scm_print_struct): Use vtable name.
647 * print.c (scm_init_print): Set name of print state type.
649 * stacks.c (scm_init_stacks): Set name of stack type.
651 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
653 * eval.c (SCM_CEVAL): Removed old implementation of internal
656 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
658 * debug.c, debug.h (scm_reverse_lookup): Added.
659 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
660 internal procedure definitions; Don't use scm_i_inner_name.
662 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
665 * eval.h: Added prototypes for multi language support functions.
667 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
668 improper lists in the low-level representation, since that will
669 cause a begin to be prepended at macro expansion.
671 * eval.c (scm_cons_source): Version of cons which copies source
672 properties from an existing cell.
673 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
675 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
676 procedure source before calling scm_unmemocopy instead of faking
679 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
681 Ported `internal defines' fix from SCM. Original ChangeLog entry:
683 1998-07-09 Radey Shouman <radey@colorage.com>
685 * eval.c (ceval_1): Modifications to allow rewriting of interal
686 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
687 body of which it is the CAR is macro expanded by m_expand_body,
688 which rewrites internal DEFINE.
690 (m_expand_body): Added.
692 (m_macroexp1): Added argument to control error checking:
693 m_expand_body may speculatively expand forms in the wrong
694 environments. Made argument number checks conditional on
697 (m_body): Added, error checks bodies and inserts the ISYM tokens.
699 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
702 (m_cond): (m_case): (m_quote): Modified to avoid destructively
703 changing their argument forms. Since m_expand_body
704 speculatively macro expands forms the process must be
707 (m_ident_eqp): Fixed to use proper environment.
709 (renamed_ident): Added DEFER_INTS_EGC.
711 Added prototypes for static functions.
717 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
718 is false, do not produce an error for unbound variables, return a
719 pointer to cell_undef instead.
721 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
725 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
726 destructively changing their argument forms. Since m_expand_body
727 speculatively macro expands forms the process must be reversible.
729 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
730 SCM_IM_LET introduced by named lets.
732 (scm_m_letstar): Use scm_m_body instead of bodycheck.
734 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
735 scm_letrec. scm_letrec1 does not check for a null binding and
736 takes an additional argument to specify the ISYM of the body. Use
737 scm_m_body instead of bodycheck.
739 (scm_m_let): Use scm_m_body instead of bodycheck.
741 (scm_m_expand_body, scm_macroexp): New.
743 (unmemocopy): Account for ISYMs introduced by scm_m_body.
745 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
746 check=1. Throw error for internal defined that have not been
747 rewritten by scm_m_expand_body.
749 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
750 Removed prototype for SCM_APPLY.
752 * tags.h: Added extern declaration of scm_isymnames.
754 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
756 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
758 * lang.c: New file: Beginning of multi-language support.
760 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
762 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
763 (scm_dynamic_wind): Added argument checking for the after guard so
764 that we don't add garbage on the dynwind chain.
765 (scm_swap_bindings): Added.
767 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
768 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
769 (scm_isymnames): New isyms for multi-language support.
771 * eval.c (scm_nil, scm_t): New symbols.
772 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
773 forms for multi-language support.
775 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
777 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
779 Renamed functions in the random function library interface
780 from scm_i_XXX --> scm_c_XXX.
782 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
784 * ports.c (scm_putc): fix line-buffering.
786 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
788 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
789 scm_set_ptob_XXX --> scm_set_port_XXX.
791 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
793 * ports.c, ports.h (scm_make_port_type): New interface for
794 creation of port types (replaces scm_newptob). Just as for the
795 smobs, we need to separate the internal representation of smob
796 types from the interface, so that we easily can add new fields and
797 rearrange things without caring about backward compatibility.
798 This change was forced by the need in GOOPS to create classes
799 representing port types.
800 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
801 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
802 scm_set_ptob_seek, scm_set_ptob_truncate,
803 scm_set_ptob_input_waiting_p): New setters.
804 (scm_newptob): Rewritten to use scm_make_port_type. For backward
806 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
807 (scm_prinport): Removed.
808 (scm_port_print): Added.
809 (scm_print_port_mode): Added.
810 (void_port_ptob, print_void_port, close_void_port, noop0):
811 Removed. Removed #include "genio.h" Added #include "objects.h",
814 * fports.c (prinfport): Moved code from ports.c.
816 (scm_fptob): Removed. Instead use new interface.
817 (scm_make_fptob): Added. (Need to create basic ports in a
818 specific order in ports.c.)
820 * strports.c (scm_stptob, prinstpt, noop0): Removed
821 (scm_make_stptob): Added.
823 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
824 (scm_make_sfport): Added.
826 * filesys.c (scm_dir_print): Don't use the port printing code.
827 Instead provide specific directory printer.
829 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
831 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
834 * smob.c (scm_smob_print): Handle non-existing type name nicely.
835 Removed #include "genio.h"
837 * objects.c (scm_make_port_classes): New function ptr.
839 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
841 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
843 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
844 allow the 1st argument to be a fdes or filename as well as a
845 port (as in the filesys.c version).
847 * filesys.c (scm_truncate_file): removed.
849 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
851 * readline.c, readline.h: Removed.
853 * objects.c, objects.h (scm_port_class): Added.
854 (scm_class_of): Look up port class in scm_port_class.
855 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
856 SCM_INOUT_PCLASS_INDEX): Added.
859 * Makefile.am: Removed genio.c, genio.x.
863 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
865 * init.c: Make sure that scm_post_boot_init_modules is called only
866 once. (Important when using a dumped image.; Thanks to Bernard
869 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
871 * guardians.c (scm_guardian_zombify): Separate scanning for
872 zombies from marking the pairs of the free list.
874 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
875 use the macros. (Thanks to Michael Livshin.)
877 * eval.c (scm_m_lambda): Let bodycheck check the body of the
878 lambda. Let your sins be purified by the blood of the lambda.
879 (Thanks to Eric Hanchrow.)
881 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
882 (Thanks to Valdis Kletnieks.)
884 Fixes for EMX from Mikael Ståldal.
886 * filesys.c: #include <io.h>, if we have it.
887 * scmconfig.h.in: Regenerated.
889 * stime.c (ftime): Delete declaration for this function --- let
890 the system supply it.
892 Cleanups from John Bley.
894 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
896 * gsubr.c: Don't include "gsubr.h" twice.
898 Cleanups for compilation on Irix 6, from David Kaelbling.
900 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
901 regex_t pointer. This is what the callers have, mostly.
902 (scm_regexp_exec): Don't forget to pass the `rx' argument to
903 scm_regexp_error_msg.
905 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
906 int. That way, if we get a warning on this line, it's more likely
907 that we're really missing bits we care about.
909 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
912 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
913 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
914 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
915 cast at all is more appropriate in every case. At the moment, we
916 assume everywhere that SCM is an integral type anyway.
918 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
920 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
921 read_pos after scm_fill_buffer.
923 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
926 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
927 fports.c (fport_fill_buffer): implement the interface change.
929 * ports.c (scm_fill_buffer): interface change: no longer increments
930 read_pos past the character that's returned. it seems clearer to
931 leave it to the caller to decide what to do (thanks Jim).
933 * vports.c (sf_fill_buffer): put the read char into the buffer
934 as well as returning it.
936 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure
939 1999-07-13 Gary Houston <ghouston@easynet.co.uk>
941 * strports.c (scm_strprint_obj): simplify. start with initial
943 (st_seek): don't allow string to be extended if seeking past
944 the end of a read-only port.
946 1999-07-12 Gary Houston <ghouston@easynet.co.uk>
948 * strports.c (st_seek): change the resize checks.
950 * ports.c (scm_ftruncate): throw error if offset works out negative.
952 * strports.c (st_flush): increase string size in blocks of
953 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
954 it's greater and reset read_buf_size.
955 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
956 to be maintained for output ports too (it holds the written
957 part of the string, while write_buf may have unwritten buffer
959 (st_truncate): rewritten.
960 (top of file): added a few notes.
962 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
964 Patch from Greg Badros:
965 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
966 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
967 (function pointer) argument to scm_make_gsubr and scm_make_subr
968 calls. This avoids warnings in C++ programs using guile-snarf.
970 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
972 * strports.c (st_grow_port): set pt->read_pos. set
973 pt->read_buf_size one less than pt->write_buf_size if there's
974 an unwritten char at the end of the string. similarly for
976 (st_resize_port): renamed from st_grow_port.
977 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
978 seek from read_end instead of write_end for SEEK_END.
979 (st_ftruncate): calculate current length using readbuf, not write
981 (scm_strport_to_string): use read_buf_size for length.
982 (stfill_buffer): don't re-initialise the readbuf.
984 1999-07-05 Gary Houston <ghouston@easynet.co.uk>
986 * strports.c (scm_strport_to_string): new procedure.
987 (scm_call_with_output_string, scm_strprint_obj): use
988 scm_strport_to_string.
989 used SCM_INUM0 instead of SCM_MAKINUM (0) in a few places.
991 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
993 * symbols.c (scm_gensym): Bugfix. (Thanks to Johannes Hjorth.)
995 Fri Jun 25 22:14:32 1999 Greg Badros <gjb@cs.washington.edu>
997 * smob.c: added scm_make_smob_type_mfpe (), scm_set_smob_mfpe ();
998 use scm_make_smob_type_mfpe to initialize "free", "flo", "bigpos",
999 and "bigneg" smob types.
1001 * smob.h: Add do ... while(0) idiom to SCM_NEWSMOB. Added
1002 SCM_RETURN_NEWSMOB macro. Added protos for new functions in
1005 * *.c: Use scm_make_smob_type_mfpe, instead of scm_newsmob, and
1006 use SCM_NEWSMOB or SCM_RETURN_NEWSMOB in constructors instead of
1007 SCM_NEWCELL and setting the CAR/CDR by hand.

1030 * ports.c (scm_read_flush): new procedure, resets the putback
1031 buffer before calling the ptob routine.
1033 * strports.c (scm_strprint_obj): bug fix: get pt from the port,
1034 not from the parameter obj. (Thanks to Eric Moore.)
1036 * ports.h: SCM_CRDY, SCM_CUC, SCM_CRDYP, SCM_SETRDY, SCM_CUNGET,
1037 SCM_CGETUN, SCM_CLRDY, SCM_TRY_CLRDY, SCM_N_READY_CHARS: deleted.

1091 trinary conditional in order for the flag computation to be
1094 1999-06-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
1096 * struct.c, struct.h:
1098 In order to support different kinds of deallocation, a destructor
1099 slot has been added to struct vtables. This allows for structs
1100 containing pointers to other memory blocks.
1102 (scm_struct_i_free): New hidden struct slot. Holds destructor for
1103 instances to this vtable.
1104 (scm_struct_free_0): New destructor: Doesn't deallocate data.

1116 scm_struct_i_size which holds the size of light structs.
1117 (scm_struct_i_n_words): This slot has changed meaning. Previously
1118 it included hidden slots. Now it indicates visible slots.
1119 (scm_alloc_struct): Clear flags.
1120 (SCM_STRUCTF_MASK): 4 new flag positions added => 12 bits.
1122 (struct_num, scm_struct_i_tag): Removed.

1169 pointers. (Thanks to Mark Elbrecht.)
1171 1999-06-19 Jim Blandy <jimb@savonarola.red-bean.com>
1173 Patch from Greg Harvey:
1174 * eq.c, eval.c, list.c, ramap.c, vectors.c: Always write parens
1175 around the condition of an `if', `while', etc., even if the
1176 condition is a macro invocation that expands to something
1177 surrounded by parens. It's more readable.
1179 * eval.c (scm_map, scm_for_each): Verify that all arguments are
1180 proper lists, and of the appropriate lengths.
1181 (check_map_args): New function. (Thanks to Greg Harvey for the
1184 1999-06-19 Michael Livshin <mike@olan.com>

1202 * gc.c (scm_mallocated): Just make this signed.
1203 (scm_igc): Check for underflow by seeing if this is negative.
1205 * gc.h (scm_mallocated): Fix declaration.
1206 (Thanks to Greg Harvey.)
1208 * ports.h: #include <sys/types.h>, to get a definition for `off_t'.

1212 * stime.c (bdtime2c): Initialize lt->gmtoff and lt->tm_zone from
1213 sbd_time. (Thanks to Eric Hanchrow.)
1215 Fix from Ken Raeburn <raeburn@raeburn.org>:
1216 * weaks.c (scm_make_weak_vector): Add another extra slot before
1217 vector contents, to be used only during garbage collection.
1218 * weaks.h (SCM_WVECT_GC_CHAIN): New macro to access it.
1219 * gc.c (scm_weak_vectors): Now a SCM instead of a SCM*, and now
1221 (scm_weak_size, scm_n_weak): Deleted.
1222 (scm_igc): Use SCM_WVECT_GC_CHAIN to build up a chain of weak
1223 vectors without allocating new storage during GC, using
1224 scm_weak_vectors as the head of the chain.
1225 (scm_mark_weak_vector_spines): Walk SCM_WVECT_GC_CHAIN chain
1226 instead of stepping through an array.
1227 (scm_gc_sweep): Update offset used to find start of weak vector to
1229 (scm_init_storage): Set scm_weak_vectors to EOL.
1231 Fix from Ken Raeburn <raeburn@raeburn.org>:
1232 * gc.c (already_in_gc): New variable.
1233 (scm_igc): Set and clear already_in_gc; abort if it's set at
1236 1999-06-14 Jim Blandy <jimb@savonarola.red-bean.com>
1238 Fix from Gary Houston:
1239 * fports.c (local_seek): Signal an error if the seek fails.
1240 * ports.c (scm_lseek): Don't check return value of port's seek
1241 function; it's its job to signal an error if there's a problem.
1243 1999-06-12 Jim Blandy <jimb@savonarola.red-bean.com>
1245 * strports.c (scm_call_with_output_string): Don't include the

1248 * ioext.c (scm_read_line): Switch to reading properly.
1250 * fports.c, fports.h, gc.c, gdbint.c, ioext.c, ports.c, ports.h,
1251 scmsigs.c, strports.c, vports.c: Install the sources which
1252 actually correspond to the changes described below. I got the
1253 ChangeLog entries and the patch from two different places...
1255 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1257 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1258 it shows up as terrible performance, as we GC constantly.
1260 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
1261 newline. A bit faster, and definitely hairier.
1262 (scm_read_line): Count newlines here instead.
1264 * strings.c (scm_take_str): New function.
1265 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h
1266 (scm_take_str): New declaration. * ioext.c (scm_read_line): Use
1267 scm_take_str, to avoid copying the string.
1269 Add some simple-minded support for line buffered ports.
1270 * ports.h (SCM_BUFLINE): New flag for ports.
1271 * init.c (scm_init_standard_ports): Request line-buffering on
1272 the standard output port.
1273 * ports.c (scm_mode_bits): Recognize 'l' as a request for line
1275 (scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
1276 and there's a newline to be written, flush the port.
1278 Gary Houston's open-buffer port patches:
1280 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
1282 * ports.c: (scm_lseek): clear buffers even if just reading current
1285 * fports.c (local_fclose): call local_fflush unconditionally.

1288 1999-04-25 Gary Houston <ghouston@easynet.co.uk>
1290 * ports.h (scm_port): make read_pos a pointer to const.
1291 strports.c: take care of rw_active and rw_randow.
1292 fports.c: scm_fport_drain_input: removed. do it all in ports.c.
1293 strports.c (scm_mkstrport): check that pos is reasonable.
1294 ioext.c (scm_ftell, scm_fseek): use lseek.
1295 (SCM_CLEAR_BUFFERS): macro deleted.
1296 ioext.c (redirect_port: use ptob fflush, read_flush.
1297 ports.h (scm_ptobfuns): add ftruncate.
1298 ports.c (scm_newptob): set ftruncate.
1300 ports.c (scm_ftruncate): new procedure.
1301 fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.
1302 strports.c (st_seek, st_grow_port): new procs.
1303 fports.h (scm_port): change size types from int to off_t.
1304 ports.c (scm_init_ports): initialise the seek symbols here
1305 instead of in ioext.c.
1306 strports.c (scm_call_with_output_string): start with an empty
1307 string, so seek and ftruncate can be used.
1309 gdbint.c: adjust string port usage.
1311 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1313 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
1314 equivalent to fflush for the read buffer.
1315 * ports.c (scm_newptob): set read_flush.
1316 ports.c (void_port_ptob): set read_flush.
1317 fports.c (local_read_flush): new proc. add to ptob.
1318 strport.c (st_read_flush): likewise.
1319 vport.c (sf_read_flush): likewise.
1320 fports.h (struct scm_fport): remove random member. there's nothing
1321 left but fdes. leaving it as a struct to allow for future changes.
1322 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1323 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1324 ptob proc if the read buffer is filled.
1326 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1328 * ports.h (scm_port): add a rw_random member and replace
1329 reading and writing members with rw_active member.
1330 SCM_PORT_READ/SCM_PORT_WRITE: new values.
1332 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
1334 * ports.h (struct scm_port_table): add writing and reading members
1335 to replace write_needs_seek: it isn't good enough for non-fports.
1336 ports.c, ioext.c, fports.c: corresponding changes.
1337 (struct scm_port_table): give it a typedef and rename to scm_port.
1338 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
1339 corresponding changes.
1341 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
1343 * ports.c (scm_newptob): bugfix: set seek member.
1344 * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
1345 and generalised to all port types.
1347 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
1349 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
1350 signals (it was only being done for handlers installed from Scheme).
1351 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
1352 waiting for input caused an EINTR error from read.
1354 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
1356 * ports.h (struct scm_port_table): make all the char members
1357 unsigned, so they convert to int without becoming negative if large.
1359 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
1361 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
1362 with threads enabled. rename this procedure to
1363 fport_wait_for_input and take a port instead of a fdes.
1364 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
1366 * readline.c (scm_readline): Applied a patch from Greg Harvey to
1367 get readline support working again: use fdopen to get FILE objects.
1369 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
1371 * gc.c (scm_init_storage): install an atexit proc to flush the
1373 (cleanup): the new proc. it sets a global variable which can be
1374 checked by the ptob flush procs to avoid trying to throw
1375 exceptions during exit. not very pleasant but it seems more reliable.
1376 * fports.c (local_fflush): check terminating variable and if set
1377 don't throw exception.
1378 * CHECKME: that the atexit proc is installed if unexec used.
1380 * throw.c (scm_handle_by_message): don't flush all ports here.
1381 it still causes bus errors.
1383 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
1384 and move to ioext.c.
1386 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
1388 * ports.c (scm_char_ready_p): check the port buffer and call the
1389 ptob entry if needed.
1391 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
1392 ptob initialisers. use it in char-ready
1394 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
1396 * vports.c (sfflush): modified to write a char (since softports
1397 currently use shortbuf.)
1399 * fports.c (scm_standard_stream_to_port): moved to init.c and
1402 * init.c (scm_init_standard_ports): make stdout and stderr
1403 unbuffered if connected to a terminal. with stdio they
1404 were line-buffered by default.
1406 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
1409 * ports.h (scm_ptobfuns): change fflush return to void.
1410 change flush proc definitions.
1412 * strports.c (scm_call_with_output_string): get size from
1413 buffer instead of port stream.
1414 (st_flush): new proc.
1416 * ports.h (struct scm_port_table): added write_end member,
1417 as an optimisation. set it where write_buf_size is set.
1419 * ports.h (struct scm_port_table): change stream from void *
1420 back to SCM. SCM presumably must be large enough to hold a
1421 pointer (and probably vice versa but who knows.)
1422 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
1424 (scm_puts): rewritten
1425 * fports.c (local_ffwrite, local_fputs): removed.
1426 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)
1427 * vports.c (sfputc, sfputs, sfwrite) likewise.
1428 * ports.c (write_void_port, puts_void_port): removed.
1429 (putc_void_port, getc_void_port, fgets_void_port): likewise.
1431 * ports.c (scm_lfwrite): rewritten using fport.c version.
1433 * fports.c (local_fputc): deleted.
1435 * ports.c (scm_add_to_port_table): initialise write_needs_seek.
1437 * ports.h (scm_ptobfuns): add seek function pointer.
1438 * fports.c: set it to local_seek, new procedure.
1441 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
1442 use ptob for seek. take ptob instead of fport arg.
1444 * ports.h (struct scm_port_table): new member write_needs_seek,
1445 replaces reading member in fport struct.
1447 * vports.c (sfgetc): store the getted char into the buffer.
1448 rename to sf_fill_buffer and install it for fill-buffer in ptob.
1449 the Scheme interface is still a procedure that gets a char.
1450 (scm_make_soft_port): set up the port buffer (shortbuf).
1452 * fports.c (local_fgetc, local_fgets): deleted.
1453 * strports.c (stgetc): likewise.
1454 * ports.c: scm_generic_fgets: likewise.
1456 * ports.h (scm_ptobfuns): add fill_buffer.
1457 * ports.c (scm_newptob): assign it.
1458 * strports.c (scm_mkstrport): set up the buffer.
1459 put just the string into the stream, not cons (pos stream).
1460 (stfill_buffer): new proc.
1462 * ports.h: fport buffer moved into port table: to be
1463 used for all port types.

1472 scm_getpeername, scm_recv, scm_send, scm_recvfrom,
1474 use SCM_FPORT_FDES. use SCM_OPFPORTP not SCM_FPORTP.
1476 * posix.c (scm_getgroups): use SCM_ALLOW/DEFER_INTS.
1477 (scm_ttyname): use SCM_FPORT_FDES.
1478 (scm_tcgetpgrp, scm_tcsetpgrp): likewise.

1485 (scm_fdopen): use scm_fdes_to_port.
1487 * ports.c (scm_init_ports): don't try to flush ports using
1488 atexit(). it's too late, errors will cause SEGV.

1492 * fports.h (SCM_FDES_RANDOM_P): new macro. use it in
1493 scm_fdes_to_port and scm_redirect_port.
1495 * ioext.c (scm_redirect_port): use setvbuf to set buffers in the
1496 new port. reset fp->random.
1498 * fports.c (scm_fdes_to_port), ports.c (scm_void_port),
1499 filesys.c (scm_opendir):
1500 restore defer interrupts while the port is constructed.
1501 (scm_setvbuf): if mode is _IOFBF and size is not supplied,
1502 derive buffer size from fdes or use a default.
1503 (scm_fdes_to_port): use setvbuf instead of creating the buffers
1506 vports.c (various places): use SCM_SSTREAM.
1507 strports.c: likewise.
1508 * gdbint.c: likewise.
1509 * ports.h (SCM_SSTREAM): new macro.
1511 * fports.c (scm_input_waiting_p): use scm_return_first, since port
1512 may be removed from the stack by the tail call to scm_fdes_waiting_p.
1514 * fports.h (SCM_CLEAR_BUFFERS): new macro.
1516 * filesys.c (scm_fsync): use SCM_FDES.
1518 * ports.c (scm_force_output): call scm_fflush.

1534 ports.c fports.c ioext.c posix.c socket.c net_db.c filesys.c:
1535 removed all uses of SCM_DEFER/ALLOW ints for now. they were mainly
1536 just protecting errno. some may need to be put back.
1538 * scmsigs.c (take_signal): save and restore errno while this
1541 *fports.c (print_pipe_port, local_pclose, scm_pipob): deleted.
1542 open-pipe, close-pipe are emulated in (ice-9 popen)
1543 ports.c (scm_ports_prehistory): don't init scm_pipob.

1658 * strop.c (scm_string_capitalize_x): Use the SCM object `s' in

1662 * strop.c (scm_substring_move_x): New function, which can handle
1663 arbitrary overlapping substrings.

1738 1999-03-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1740 * numbers.c (isfinite): Define this macro if not defined: Return a
1741 non-zero value if X is finite. (From ISO C 9x standard.)

1794 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1796 Most of this batch of changes is about how to deal with extended
1797 types when an object system is loaded into Guile. A nice object
1798 system is capable of representing Guile's types as class objects.
1800 For example, we want a regular expression to be of class <regex>.
1801 But regular expressions are smobs which aren't under direct
1802 control of the object system, so there has to be some mechanism
1803 which informs the object system that a new class should be created
1804 which can represent the smob type. I call this a "wrapper class".
1806 * objects.c: #include "smob.h";
1807 (scm_class_keyword): Removed. (Class is automatically created by
1809 (scm_smob_class): Array of smob classes indexed by smobnum.
1810 (scm_make_extended_class): "Plugin" function pointer for creation
1811 of wrapper classes for smob and struct types.
1812 (scm_class_of): Handle compiled closures. (Currently regarded as
1814 Use scm_smob_class to handle smob types;
1815 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1816 through scm_smob_class;
1819 * smob.c (scm_newsmob): Also create a wrapper class if
1820 scm_smob_class has been initialized.
1822 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1823 type code and smobnum.
1825 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1826 (scm_struct_table): Weak key table with auxilliary information for
1827 struct types. Currently used for names and wrapper classes.
1828 (scm_struct_ihashq): Hash function for structs.
1829 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1830 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1831 for accessing names of vtables. The record implementation in
1832 boot-9.scm currently uses the setter to record the name of record
1833 types. When the object system is initialized, it can use this
1834 information to create wrapper classes with suitable names.
1835 (scm_init_struct): Allocate scm_struct_table.
1836 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1837 (struct tags are a finite resource and we might want to restrict
1838 the use of tags to vtables only. E.g., Goops only uses tags for
1840 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1842 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1845 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1846 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1847 Used for access of struct table entries.
1849 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1850 (scm_hash_fold): New procedure. Used to process all entries in a
1851 hash table (in no particular order).
1853 Argh! For the umpteenth time I got compilation errors because of
1854 the "intuitive" name `kw'. This has to have an end:
1856 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1857 "kw" --> "keywords" everywhere.
1858 (I doubt that this will cause big compatibility problems since the
1859 application interface is unaffected.)
1861 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1863 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1865 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1866 column inums to native form.
1868 Improvement of backtraces: Introduces a new stack narrowing
1869 specifier, #t, for the inner cut. (See further in the comments in
1870 stacks.c:narrow_stack ().)
1872 * procprop.c, procprop.h (scm_sym_system_procedure): New symbol.
1873 (Used to flag certain system procedures which shouldn't turn up in
1876 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1877 modules which aren't "user" modules and the code of which
1878 shouldn't turn up in backtraces.)

1881 Extract the lookup closure from an environment.
1882 (scm_system_module_env_p): New function: Return non-#f if MODULE
1885 * stacks.c: #include "eval.h"; #include "procprop.h";
1886 (narrow_stack): Handle new narrowing specifier #t.
1888 * debug.c (scm_procedure_name): Use name property in the default
1891 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
1893 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1895 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1896 procedure throughout.
1898 * print.c (scm_iprin1): Removed extraneous space when printing
1899 procedure-with-setters.
1901 Entity and operator setter slots were introduced as a complement
1902 to the <procedure-with-setter> type in order to support entities
1903 and operators with setters in a reasonable and efficient way.
1904 * procs.c (scm_procedure, scm_setter): Handle entity and operator
1907 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

1917 1999-03-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1919 * objects.h (SCM_OBJ_CLASS_REDEF): New macro: Find class slots
1920 directly through the instance.
1922 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1924 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1925 scm_struct_i_flags instead of scm_vtable_index_layout!
1927 * list.c (scm_list_star): New procedure.
1929 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1931 * debug.c (scm_init_debug): Added scheme level constant

2010 SYMB now point to const.
2012 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2014 * print.c (scm_iprin1): Use scm_procedure_name instead of
2015 scm_procedure_property for compiled closures.
2017 * tags.h (scm_tc7_pws): New procedure type. Four representations
2018 for procedure-with-setters were considered before selecting this
2021 1. A closure where the CODE and ENV slots are used to represent
2022 the getter and a new SETTER slot is used for the setter. The
2023 original getter is stored as a `getter' procedure property. For
2024 closure getters, the CODE and ENV slots contains a copy of the
2025 getter's CODE and ENV slots. For subr getters, the CODE contains
2028 2. A compiled closure with a call to the getter in the cclo
2029 procedure. The getter and setter are stored in slots 1 and 2.
2031 3. An entity (i.e. a struct with an associated procedure) with a
2032 call to the getter in the entity procedure and the setter stored
2033 in slot 0. The original getter is stored in slot 1.
2035 4. A new primitive procedure type supported in the evaluator. The
2036 getter and setter are stored in a GETTER and SETTER slot. A call
2037 to this procedure type results in a retrieval of the getter and a
2038 jump back to the correct eval dispatcher.
2040 Representation 4 was selected because of efficiency and
2043 Rep 1 has the advantage that there is zero penalty for closure
2044 getters, but primitive getters will get considerable overhead
2045 because the procedure-with-getter will be a closure which calls
2048 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
2049 <procedure-with-setter>, but together with rep 2 it suffers from a
2050 three level dispatch for non-GOOPS getters:
2052 cclo/struct --> dispatch proc --> getter
2054 This is because the dispatch procedure must take an extra initial
2055 argument (cclo for rep 2, struct for rep 3).
2057 Rep 4 has the single disadvantage that it uses up one tc7 type
2058 code, but the plan for uniform vectors will very likely free tc7
2059 codes, so this is probably no big problem. Also note that the
2060 GETTER and SETTER slots can live directly on the heap, using the
2061 new four-word cells.
2063 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,
2064 SCM_SETTER): New macros.

2083 * evalext.c, evalext.h (scm_m_generalized_set_x): New memoizing
2085 (scm_init_evalext): Call scm_make_gsubr for
2086 scm_m_generalized_set_x.
2088 * eval.c, debug.c, tags.h (SCM_IM_SET_X): Renamed from SCM_IM_SET.
2090 * eval.h: Declare scm_s_set_x, scm_sym_set_x;
2092 * eval.c: Renamed "set" --> "set_x" in various names for
2093 consistency of name correspondence between Scheme and C;
2094 Renamed scm_i_set_x --> scm_sym_set_x and made global.
2095 Renamed s_set_x --> scm_s_set_x and made global.
2097 1999-01-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2099 * random.c (scm_i_random_bignum): Made independent of endianness.

2117 scm_rstate from seed.
2118 (scm_copy_random_state, scm_seed_to_random_state): New functions.
2119 (scm_make_random_state): Removed.
2121 * random.c (scm_make_random_state): Use scm_i_make_rstate().

2129 1999-01-11 Roland Orre <mdj@mdj.nada.kth.se>
2131 * sort.c (scm_merge, scm_merge_list_x): Bugfix: Place elements
2132 from first arg before equal elements in second arg in result.
2133 (scm_merge_list_step): Bugfix: Don't presume that arguments in a C
2134 function call are executed in a well defined order.
2136 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2138 * alloca.c (alloca): Cast value returned by malloc. (Thanks to
2141 1999-01-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2143 * random.c: Removed alloca includes.
2145 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
2147 * Makefile.in: This changed, for some reason I don't really
2148 understand, when I ran automake in the top level directory. This
2149 may be contamination by Cygnus internal releases. If you re-run
2150 automake and this change gets reverted, don't worry about it.
2152 1999-01-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2154 * sort.c, sort.h: New files: Implement slib's and scsh's sort

2167 * random.c, random.h: New files: Random number support.
2168 Interface same as slib's.
2170 * Makefile.am: Added random.c, random.h, random.x.
2172 * init.c: #include "random.h";

2175 1998-12-23 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2177 * Makefile.am: New files: guardians.c, guardians.x, guardians.h
2179 * guardians.c, guardians.h (scm_make_guardian,
2180 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
2181 scm_get_one_zombie, scm_init_guardian): This is an implementation
2182 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
2183 David Eby (1993) "Guardians in a Generation-Based Garbage
2184 Collector" ACM SIGPLAN Conference on Programming Language Design
2185 and Implementation, June 1993 ftp://ftp.cs.indiana.edu
2186 /pub/scheme-repository/doc/pubs/guardians.ps.gz
2187 Author: Michael N. Livshin.
2189 * gc.h (SCM_MARKEDP, SCM_NMARKEDP): New macros.
2191 * gc.c (scm_igc): Call scm_guardian_gc_init and
2192 scm_guardian_zombify.

2196 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2198 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
2201 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2203 Move the procedure slots of entities to invisible slots (so that
2204 we can have operator class objects which themselves are entities).
2205 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
2206 SCM_STRUCTF_ENTITY): New constants.
2208 * struct.c (scm_make_struct): Allocate "invisible" room for
2209 procedures if SCM_STRUCTF_ENTITY is set in vtable.
2211 * gc.c (scm_gc_mark): Mark entity procedures.

2218 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
2219 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
2221 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
2223 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
2224 of syntactic forms, similar to SCM_PROC.
2225 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
2226 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
2227 for the name symbols when needed.
2229 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
2231 * Makefile.in: Regenerated.
2233 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
2235 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
2236 take the address of _into; it might be a register. Just have
2237 scm_debug_newcell return the new cell.
2238 * gc.c (scm_debug_newcell): Just return the new cell, instead of
2239 taking the address of a place to store it as an argument.
2240 * gc.h (scm_debug_newcell): Change declaration.
2241 (Thanks to Greg Harvey.)
2243 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2245 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
2246 Replaces old names serial-array-copy! and serial-array-map!.

2252 * smob.c (freeprint): New function.
2253 (freecell): Use it to print freed objects, for slightly easier
2256 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2258 * backtrace.c (display_frame): Made more robust. Doesn't throw an
2259 error if no source properties can be found for a frame. (Thanks
2260 to Christian Lynbech.)
2262 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2264 * objects.h: Removed slots direct_supers and direct_slots from the
2265 definitions of the rudimentary classes described by objects.h.
2267 * objects.c, objects.h (scm_entity_p): New procedure. Together
2268 with the predicates scm_procedure_p and scm_struct_p, this
2269 predicate makes it possible to differ between structs, entities
2272 * modules.c, modules.h (scm_resolve_module): New function.
2274 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2276 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
2277 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
2280 * objects.c (scm_entity_p): New procedure.
2282 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
2283 for asubrs, rpsubrs, lsubrs and lsubr_2s.
2285 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2287 * procprop.h (scm_i_procedure_arity): Added declaration.
2289 * procprop.c (scm_i_procedure_arity): Made global; New code to
2290 handle operators and entities.
2291 (scm_procedure_property): No need to call scm_procedure_p since
2292 scm_i_procedure_arity now does all necessary type checking.
2293 Added #include "objects.h".
2295 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
2296 s_add_hook_x --> s_remove_hook_x.
2297 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
2298 Added #include "procprop.h"
2300 * feature.c, feature.h (scm_reset_hook_x): New procedure.
2301 (scm_make_hook): Optional argument defines number of arguments to
2303 (scm_make_named_hook): Take number of args as second arg.
2304 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
2305 boot-9.scm for a while); First arg is the hook. The rest are
2306 arguments passed on to the hook procedures.
2308 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
2310 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2311 scm_logbit_p): Do the computation in ulongs. This is not as nice
2312 as doing it in bignums, but at least it's good enough for
2313 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2315 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2316 subexpressions. (Thanks to Charbel Jacquin.)
2318 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
2320 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
2321 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2322 (scm_make_named_hook): New function.
2324 * feature.c: Added #include "eval.h".
2326 * modules.c (scm_make_module): Beautify the module.
2328 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2330 * modules.c, modules.h: New files: C interface to modules. (This
2331 is necessary in order to interface the object system to Guile
2332 properly. The guts of these modules will be replaced by the new
2333 module system in the future.)
2335 * init.c: Added #include "modules.h"
2336 (scm_boot_guile_1): Call scm_init_modules.
2337 (invoke_main_func): Call scm_post_boot_init_modules.
2339 * Makefile.am: Added modules.c, modules.x, modules.h.
2341 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
2343 * procs.c: #include "objects.h"
2344 (scm_procedure_p): Return #t also on structs which are operators.
2346 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
2347 <operator-metaclass> and <entity-class> to <standard-class>,
2348 <operator-class> and <entity> in order to conform with STKlos
2351 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
2352 which isn't an operator.
2353 (SCM_APPLY): Ditto, but jump to badproc.
2355 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
2357 * eval.c (SCM_CEVAL): Allow structs implanted in code.
2358 Previously, structs implanted in code were interpreted as forms
2359 the operator of which was a gloc. We solve this by checking for
2360 the zero in the emulated vcell in the struct vtable. Since
2361 implanted structs always will look like forms with a gloc
2362 operator, execution will only be slowed down by maximally one
2363 extra test-and-branch per application.
2365 * evalext.c (scm_definedp): Removed check for isyms; Added a
2366 second optional argument: It is now possible to supply an
2367 evaluation environment in which to look for the symbol.
2369 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2371 * readline.c (scm_init_readline): Set
2372 rl_basic_word_break_characters. (Thanks to Ian Grant.)
2374 * coop.c (coop_condition_variable_wait): Removed
2375 (coop_condition_variable_wait_mutex): Folded logic of
2376 coop_mutex_unlock into coop_condition_variable_wait_mutex to
2377 prevent condvar signal lossage. Previously, another thread could
2378 start to run after unlocking the mutex but before putting the
2379 current thread on the wait queue. If that thread then would
2380 signal the first, the signal would be lost. (Thanks to Christian
2383 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2385 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
2388 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2390 * objects.c (scm_i_make_class_object): Renamed from
2391 make_class_object; exported; error checking moved to
2392 scm_make_class_object and scm_make_subclass_object.
2393 (scm_make_class_object, scm_make_subclass_object): Use
2394 scm_i_make_class_object.
2395 (scm_make_subclass_object): Let the subclass have same metaclass
2398 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2400 * debug.c (scm_debug_options): Bugfix: Set the value of
2401 scm_stack_checking_enabled_p after setting debug options;
2402 #include "stackchk.h". (Thanks to Richard Polton.)
2404 1998-11-13 Radey Shouman <rshouman@metro2000.com>
2406 * unif.c (scm_array_contents): removed unnecessary test for 0
2409 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2411 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
2412 Replaced by macro `collect' in boot-9.scm.
2414 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2416 * eval.c (scm_copy_tree): Copy source properties if existent.
2418 * debug.c (scm_start_stack): Copy source when evaluating. (If we
2419 don't, we may end up passing memoized source to a transformer.)
2421 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2423 * stack.c (get_applybody): Help function which lookups the first
2424 body form of the apply closure.
2425 (read_frames): Prevent the source of the first form of the apply
2426 closure from being recorded. This would only be confusing.
2428 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
2429 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
2431 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
2433 * stacks.c (read_frame): Bugfix: Removed lingering `else'
2435 (read_frames): Use SCM_MACROEXPP.
2437 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2439 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
2440 don't contain interesting information since all arguments are
2441 present in the frame which applies the compiled closure anyway.);
2442 Skip the transformer application frames.
2444 * print.c (scm_iprin1): Print gsubrs as primitives.
2446 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2448 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
2450 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
2451 that we can identify these in a backtrace. (This change doesn't
2452 introduce any significant speed penalty.)
2454 * eval.c: Added note about `serial-map' using scm_map.
2456 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2457 readline options. They should reside in their own options array.
2459 * readline.c, readline.h (scm_readline_options,
2460 scm_readline_opts): Moved readline options here.
2462 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2464 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2465 SCM_ROCHARS instead of SCM_CHARS.
2467 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2468 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2470 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2472 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2473 This is quite important since the latter clears the
2474 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2475 every single character read...
2477 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2479 * print.c (scm_iprin1): Removed suspect looking (and indeed
2480 malevolent) semicolon after test for user supplied closure print
2481 procedure. (Thanks to Telford Tendys.)
2483 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2484 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2485 starting to search the list. Removed call to sloppy_mem_check.
2487 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2488 procedures: Same as scm_delq_x et al, but delete maximally one
2491 * options.c (scm_options, scm_init_options): GC-protect option
2492 values of type SCM. (Thanks to Telford Tendys.)
2494 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2496 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2497 make sure that there always is a "real" scm_lookupcar.
2499 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2501 * read.c, read.h (scm_read_opts): New read options
2502 "history-length" and "history-file".
2503 (scm_read_options): Stifle history to history length.
2505 * readline.c (scm_read_history, scm_write_history): New procedures.
2507 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2509 * eval.h (scm_macro_eval_x): Removed declaration.
2511 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2512 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2513 Renamed and made global.
2515 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2516 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2518 * evalext.c, evalext.h: New files. Contain non-R5RS things
2519 having to do with evaluation.
2521 * evalext.c (scm_serial_map): New procedure: Version of `map'
2522 which guarantees that the procedure is applied to the lists in
2524 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2525 returns a list of the results of the body forms instead of the
2526 result of the last body form.
2527 (scm_definedp, scm_m_undefine): Moved from eval.c
2529 * evalext.h (scm_m_sequence_to_list): Added declaration.
2531 * macros.c, macros.h: New files.
2532 (scm_procedure_to_syntax, scm_procedure_to_macro,
2533 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2534 scm_macro_name, scm_macro_transformer): Moved from eval.c
2535 (scm_make_synt): Moved from eval.c
2537 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2539 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2542 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2544 * debug.c, print.c: Added #include "macros.h".
2546 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2548 This change adds the ability to use `unread-char' multiple times
2549 without interspersed reads and adds the new procedure
2550 `unread-string'. The change is optimized for the common case of
2551 unreading a single character. This is also the reason behind the
2552 choice to store characters in the port itself: in most cases no
2553 extra malloc is required.
2555 The amount of code in some macros in ports.h has been increased to
2556 the extent that they would fit better as C functions, but, since
2557 this code belongs to the port representation, such functions
2558 should be placed in ports.c which would cause calls back and forth
2559 between ports.c and genio.c. That is not good for performance.
2560 Also, keeping them as macros allows the compiler to do some
2561 optimizations which are needed to make the current interface
2562 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2564 One benchmark (Guile startup time) indicates an increase of
2565 loading speed of 1%. Another (reading (using `read') boot-9.scm
2566 10 times) shows no change in performance.
2568 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2569 made to find a beautiful solution.)
2571 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2572 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2573 character. (SCM_CLRDY clears all.)
2574 (SCM_N_READY_CHARS): New macro: Returns number of unread
2575 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2576 (struct scm_port_table): New fields: `entry' contains port table
2577 index, `cp' points to last unread char, `cbuf' is the buffer for
2578 unread chars, `cbufend' points after end of the character buffer.
2580 * ports.h, ports.c (scm_unread_string): New procedure.
2581 (scm_grow_port_cbuf): New function.
2583 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2585 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2586 to read unread characters. Use SCM_TRY_CLRDY instead of
2589 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2591 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2593 * genio.c, genio.h (scm_ungets): New function.
2595 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2598 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2600 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2601 declarations. (Thanks to Russ McManus.)
2603 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2605 * numbers.c (num2long): As a software archeologist, I'm proud of
2606 this finding! :) Preliminary dating suggests an almost 4 year old
2607 remnant from the SCM ancestor. The sample has been removed from
2608 the finding site and is now safely stored in the repository.
2610 * numbers.h: Removed prototype for num2long.
2612 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2614 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2615 array as second arg.
2616 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2617 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2618 * gh.h: Updated and added prototypes.
2620 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2622 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2624 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2626 * guile-snarf.in: Never generate an empty file. (Thanks to
2629 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2630 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2631 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2632 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2633 gh_new_procedure5_0): Specify argument types, to appease C++
2634 compilers. (Thanks to Brad Bowman.)
2636 Bug reports from Russ McManus:
2637 * guile-snarf.in: If the CPP environment variable is set, use that
2638 as the C preprocessor, instead of the preprocessor autoconf
2640 * snarf.h (SCM_PROC): Cast the function pointer passed to
2641 scm_make_gsubr, to satisfy C++.
2643 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2644 Use the handler passed, instead of ignoring it and using
2645 gh_standard_handler. (Thanks to Etienne Bernard.)
2647 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2649 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2652 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>

2669 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
2672 * script.c (scm_compile_shell_switches): Define
2673 use-emacs-interface in the root module, so the repl code can see
2674 it. See today's change to top-repl in ice-9/boot-9.scm.
2676 * filesys.c (set_element, get_element): Make sure that `element'
2677 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2678 Boekemeier and Jorgen "forcer" Schaefer.)
2680 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2682 * chars.c (scm_charnames): In ASCII character name table, make
2683 newlines print as #\newline by default, not #\nl.
2685 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2686 alphabetical order. Oh thrills. But it helps me know how far
2687 along in the compilation I am.
2688 * Makefile.in: Regenerated.
2690 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2692 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2693 #bytes(...) to #y(...), and syntax for short vectors from
2694 #short(...) to #h(...). This may seem nutty, but, like the other
2695 uniform vectors, byte vectors and short vectors want to have the
2696 same print and read syntax (and, more basic, want to have read
2697 syntax!). Changing the read syntax to use multiple characters
2698 after the hash sign breaks with the conventions used in R5RS and
2699 the conventions used for the other uniform vectors. It also
2700 introduces complexity in the current reader, both on the C and
2701 Scheme levels. (The Right solution is probably to change the
2702 syntax and prototypes for uniform vectors entirely.)
2704 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2706 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2707 (Thanks to Jorgen "forcer" Schaefer.)
2708 * ports.h (SCM_NOFTELL): New flag.
2709 * fports.c (local_fgets): If it's set, use the generic fgets.
2710 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2712 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2714 * script.c (scm_compile_shell_switches): Add handling of -q switch
2715 (inhibit loading of user init file).
2716 (scm_shell_usage): Add usage text for -q switch.
2717 (scm_compile_shell_switches): Always load user init file first if
2718 it is loaded at all.
2720 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2722 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2723 and is now broken under NetBSD. I can't fathom what it's trying
2724 to do, so I've replaced it with something that I do understand,
2725 which seems to work, and which isn't broken on NetBSD. "Progress?
2726 You Decide." (Thanks to Perry Metzger.)
2728 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2729 signed/unsigned comparison.
2731 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2733 Warning fixes from Greg Harvey:
2734 * unif.c (scm_array_set_x): initializer for pos
2735 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2736 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2737 initializers for field_type, since EGCS so desparately wants to
2739 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2740 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2741 when GUILE_DEBUG is defined.
2742 * dynwind.h (scm_wind_chain): Same.
2743 * ports.h (scm_pt_size, scm_pt_member): Same.
2744 * print.h (scm_current_pstate): Same.
2745 * procs.h (scm_make_cclo): Same.
2747 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2749 Handle short and long long uniform arrays properly. (Thanks to
2751 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2752 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2753 scm_tc7_llvect (long long vectors).
2755 Change the way libguile and boot-9.scm are timestamped, to try to
2756 get rid of these spurious mismatch warnings. Now both
2757 libguile/versiondat.h and ice-9/version.scm are generated directly
2758 by the configuration process, rather than having version.scm
2759 generated directly, and libguile/versiondat.h generated by the
2760 Makefile, which is generated by configure. It seems that
2761 sometimes the Makefile would change, but versiondat.h depends on
2762 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2763 * Makefile.am (versiondat.h): Target removed; this is generated
2764 directly by the configure script now.
2765 (BUILT_SOURCES): Remove versiondat.h.
2766 * versiondat.h.in: New file, transformed by the configure script
2768 * Makefile.in: Regenerated.
2770 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2771 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2772 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2773 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2774 if we want to use them in a header file some day, we can. (Thanks
2775 to Michael Livshin.)
2777 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2778 SCM numbers, so we won't have rollover problems; the range of a
2779 signed long in milliseconds is about 25 days. (Thanks to Karl
2782 Don't redefine sleep and usleep; fix this problem now.
2783 * coop.c (sleep, usleep): Remove declarations; we don't use or
2784 redefine these any more.
2785 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2786 job of usleep and sleep in a thread-friendly way. We can use
2787 these in the rest of Guile. Define versions for systems both with
2788 and without iselect.
2789 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2790 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2791 we're just using it, not redefining it, we can use a K&R style
2793 (sleep): Declare this, too, if the system hasn't.
2794 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2795 scm_uthread_sleep if they're available; otherwise, just call the
2797 * scmconfig.h.in: Regenerated.
2799 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2801 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2803 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2805 * threads.c: Doc fix.
2807 The argument type of usleep varies from system to system,
2808 as does the return type. We really shouldn't be redefining usleep
2809 at all, but I don't have time to clean that up before the 1.3.
2810 release. It's on the schedule for afterwards. (Thanks to Julian
2812 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2814 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2815 * scmconfig.h: Regenerated.
2817 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2818 right way to handle system variation. Autoconf's approach is the
2820 * simpos.h (scm_software_type): Declaration deleted.
2822 * script.c (scm_find_executable): Don't test if unix is #defined
2823 here; first, NetBSD doesn't #define it, and second, it's the wrong
2824 way to go about these things. (Thanks to Perry Metzger.)
2825 (dld_find_executable): Delete this MSDOS support code. This isn't
2826 the way we want to support this; it needs to be rethunk at a
2829 * genio.c (scm_do_read_line): Don't just politely check that the
2830 line was either non-empty or EOF. Abort if it's empty and not
2833 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2835 * scmconfig.h.in: Regenerated.
2837 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2840 * genio.c (scm_do_read_line): Count lines correctly when the file
2841 doesn't end in a newline.
2843 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2845 * genio.c (scm_do_read_line): Maintain the line count correctly.
2846 (Thanks to Harvey J. Stein and Greg Harvey.)
2848 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2851 * numbers.c (big2str): Protect t from garbage collection until
2852 we're done. (Thanks to Gary Houston.)
2854 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2856 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2858 * Makefile.in: Regenerated.
2860 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2861 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2864 Do magic to mix reads and writes on stdio FILE-based ports.
2865 (Thanks to Christian Lynbech.)
2866 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2868 (pre_read, pre_write): New functions.
2869 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2870 local_fputs): Call them.
2871 (local_fflush): Mark the port as ready for reading and writing.
2872 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2873 flags on new port objects. This might not be accurate --- who
2874 knows what state the FILE * is in when we get it --- but it won't
2875 do extraneous calls to fflush or fseek, so it's no worse than the
2876 behavior before this change.
2877 * ports.h: Add comment.
2879 Centralize the creation of port objects based on stdio FILE * in
2880 fports.c; don't just throw them together anywhere.
2881 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2882 what the rest of Guile wants. Don't set the revealed count;
2883 that's only appropriate for stdin, stdout, stderr.
2884 (scm_standard_stream_to_port): This function does set the revealed
2886 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2887 not scm_stdio_to_port.
2888 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2889 * fports.c (scm_open_file): Same.
2890 * posix.c (scm_pipe): Same.
2891 * socket.c (scm_sock_fd_to_port): Same.
2892 * ioext.c (scm_fdopen): Same.
2893 (scm_freopen): Moved from here to...
2894 * fports.c (scm_freopen): ... here. This is really something that
2895 munges the internals of an fport, so it should go here.
2896 * fports.h (scm_stdio_to_port): Adjust prototype.
2897 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2898 * ioext.h (scm_freopen): Prototype removed.
2900 * filesys.c (set_element, get_element): This can work on both pipe
2901 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2904 * scmconfig.h.in: Regenerated.
2906 Change the definition of the functions in scm_ptobfuns so that
2907 they get passed the port object, not the port's stream.
2908 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2909 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2910 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2911 Pass the port itself to the scm_ptobs function.
2912 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2913 scm_generic_fgets): Same.
2914 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2915 getc_void_port, fgets_void_port, close_void_port): Just change the
2916 argument names; these functions don't really do anything.
2917 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2918 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2919 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2920 Also, use prototyped definitions, and get rid of the extra
2922 (scm_fptob, scm_pipob): We don't need casts here any more.
2923 * strports.c (prinstpt): Use prototype declarations.
2924 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2925 and use SCM_STREAM to get the string info. Also, use prototyped
2926 definitions, and get rid of the extra declarations.
2927 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2930 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2931 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2933 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2934 scm_fgets, for consistency.
2935 (scm_fptop, scm_pipob): References updated.
2937 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2939 Include the source location in error messages for scripts.
2940 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2941 stack is still there when we catch the error.
2942 * throw.c (handler_message): If we are handling an error with a
2943 message, then put together the proper arguments and call
2944 scm_display_error, instead of scm_display_error_message. That
2945 displays source location, if it can find it.
2947 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2949 * gc.c (scm_unprotect_object): Change this so that calls to
2950 scm_protect_object and scm_unprotect_object nest properly.
2951 (scm_protect_object): Doc fixes.
2953 * strings.c (scm_string_set_x): Require the argument to be a
2954 writable string, not a substring or a symbol.
2955 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2956 (Thanks to John Redford and Charbel Jacquin.)
2958 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2960 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2962 * eval.c (safe_setjmp): Remove this misunderstanding.
2963 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2966 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2968 * libguile.h: Mark these as C declarations, for compilation by C++
2971 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2972 __cplusplus clause. I seriously doubt this ever worked the way
2973 the author seems to have intended.
2975 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2977 Utterly needless cleanups to hopelessly messy code.
2978 * ports.c: Doc fixes.
2979 (scm_fflush): Moved to ...
2980 * genio.c (scm_fflush): ... here, amongst all the other port
2981 method invocation functions.
2982 * genio.h, ports.h: The prototype moves too.
2984 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2986 * backtrace.c (display_error_body): The current frame does not
2987 always have a parent frame; consider a function called directly
2988 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2991 * alloca.c (alloca): Undo yesterday's changes, and simply call
2992 malloc directly for storage, and abort if we don't get what we
2993 want. The situation is much simpler --- just call malloc. Emacs
2994 has bizarre/evil requirements (signal handlers might malloc unless
2995 you set this global flag, so you have to set the flag around all
2996 calls to malloc) which we are certainly not going to conform to,
2997 so we can do the simple and obvious thing.
2999 * coop.c (coop_condition_variable_wait): Make this function
3000 static. It's only useful internally --- you should never just
3001 wait on a condition variable.
3002 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
3004 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3006 * unif.c (scm_array_set_x): Accept any kind of number as an
3007 element for a uniform vector of doubles. This is more consistent
3008 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
3010 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
3011 works; I can't conveniently test it myself. (Thanks to Dvid
3012 Tillman for the bug report.)
3014 * init.c: Doc fixes.
3016 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
3017 from here, not from scm_compile_shell_switches (which is a pretty
3018 dumb place to do it).
3019 (scm_load_startup_files): New function.
3020 (scm_ice_9_already_loaded): Variable moved to here from script.c.
3021 * script.c (scm_compile_shell_switches): Don't load the startup
3023 (scm_ice_9_already_loaded): Variable moved.
3024 * init.c (scm_load_startup_files): Prototype for new function.
3025 * gh_init.c (gh_enter): Doc fix.
3027 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3029 Some anti-warning changes from Greg Harvey.
3030 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
3031 warnings when it doesn't understand our NORETURN declarations in
3033 * posix.c (scm_mknod): Similar.
3035 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3037 * posix.c (scm_getpwuid): If we can't find an entry, return our
3038 own message, instead of using scm_syserror --- the getpwMUMBLE
3039 functions don't set `errno' to anything interesting.
3041 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3043 Get rid of warnings from the cooperative threading system.
3044 * threads.h (scm_single_thread_p, scm_yield,
3045 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
3046 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
3047 scm_wait_condition_variable, scm_signal_condition_variable): Add
3048 prototypes for these Scheme-visible functions.
3049 * coop-defs.h (coop_next_runnable_thread,
3050 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
3051 Prototypes for these here, even though they're from iselect.c.
3052 (coop_condition_variable_wait, coop_join): Add prototypes.
3053 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
3054 scm_threads_free_condvar): Make these smob functions static.
3055 * coop-threads.h (coop_init): Give this a real prototype.
3056 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
3057 (coop_next_runnable_thread): No need to provide prototype; it's in
3060 * scmconfig.h.in: .detarenegeR
3062 * iselect.c, threads.c: Doc fixes.
3064 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
3066 * Makefile.in: Regenerated with a patched automake, to get
3067 dependency generation right when using EGCS.
3069 * inet_aton.c (inet_aton): Add prototype, to remove compiler
3070 warning. (Thanks to Robert Pluim.)
3072 * inet_aton.c (inet_aton): Reassure the compiler that the
3073 arguments to the <ctype.h> macros are all unsigned characters, not
3076 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
3078 Getting rid of more warnings...
3079 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
3080 today's change to ../configure.in.
3081 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
3082 * scmconfig.h.in: Regenertaded.de.,.__
3083 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
3084 (scm_localtime, scm_mktime): Use a const char * to manipulate the
3087 * readline.c: Doc fix.
3088 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
3089 * readline.h (scm_filename_completion_function): Add prototype.
3090 (scm_init_readline): Make this into a prototype.
3092 * readline.c (scm_filename_completion_function): Use SCM_PROC to
3093 declare this, instead of calling scm_make_subr manually.
3095 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
3097 * readline.h (scm_init_readline): Add prototype for this.
3098 (scm_init_readline): Make this a real prototype.
3100 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
3102 Warning fixes from Maciej Stachowiak:
3103 * backtrace.h (scm_display_application, scm_backtrace): Add
3105 * debug.c (scm_m_start_stack): Make this function static.
3106 * fluids.h (scm_fluid_p): Add prototype.
3107 * procprop.c (scm_i_procedure_arity): Make this function static.
3108 * regex-posix.c (scm_regexp_error_msg): Make this function static.
3109 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
3110 * root.h (scm_dynamic_root): Add external prototype.
3111 * scmsigs.h (scm_usleep): Add external prototype.
3112 * script.h (scm_init_script): Use prototype, not K&R decl.
3113 * stacks.h (scm_stack_id): Add external prototype.
3114 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
3116 1998-09-30 Mark Galassi <rosalia@cygnus.com>
3118 * gh.h: took out the definitions of vset and vref, since they are
3119 replaced by the proper vector routines that correspond to the R4RS
3122 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
3124 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
3125 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
3126 third argument, a C expression that should result in a SCM value,
3127 which is used to initialize the variable. Reimplemented
3128 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
3131 * version.h (scm_libguile_config_stamp): Add prototype.
3132 (From Maciej Stachowiak.)
3134 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
3136 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
3137 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
3139 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
3141 * print.c (scm_iprin1): Rather than having one i, and using it in
3142 several places, declare a fresh i local to each block where it is
3143 used, and give it a signedness appropriate to its use in each case.
3144 (scm_iprlist): Same.
3146 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
3147 comparison warnings.
3149 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
3150 signed/unsigned clashes.
3152 * posix.h (scm_tmpnam): Added prototype.
3154 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
3155 scm_make_subclass_object): Add external prototypes.
3157 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
3158 comparison is okay here.
3160 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
3162 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
3163 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
3165 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
3168 * load.c (swap_port): Make this function static.
3170 * load.c (scm_search_path): Make max_path_len and max_ext_len
3171 unsigned, since they're compared against string sizes.
3173 * load.c (init_build_info): Make i unsigned.
3175 * ioext.h (scm_read_line): Add prototype.
3177 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
3178 scm_hash_fn_remove_x): Make hash bucket index local variable k
3179 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
3180 accurately as possible.
3182 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
3183 comparisons, and range checking to make sure those casts are
3186 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
3187 signed/unsigned comparisons.
3189 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
3190 avoid signed/unsigned comparisons.
3191 * smob.h (scm_numsmob): Change extern declaration to match.
3193 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
3194 avoid signed/unsigned comparisons.
3195 * ports.h (scm_numptob): Change extern declaration to match.
3196 (scm_current_load_port, scm_set_port_line_x,
3197 scm_set_port_column_x): New prototypes.
3199 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
3200 test code, and it causes warnings.
3202 * gh.h (gh_int2scmb, gh_uniform_vector_length,
3203 gh_uniform_vector_ref): Added prototypes.
3205 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
3206 debugging support unconditionally. That's backtrace.c, stack.c,
3207 debug.c, and srcprop.c.
3208 (EXTRA_libguile_la_SOURCES): Omit those from here.
3209 * Makefile.in: Regenerated.
3211 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3213 * options.c (scm_options): Bugfix: Allow empty list of options!
3215 * debug.c, debug.h (scm_single_step): Removed.
3216 (scm_with_traps): New procedure. This procedure could easily be
3217 written in Scheme but needs to be highly optimized.
3219 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
3221 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
3222 Check SCM_TRAPS_P before trapping.
3224 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
3226 Changes to avoid signed/unsigned comparison warnings.
3227 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
3228 (scm_gc_sweep): Make n and j local to the blocks they're used in,
3229 so they can have appropriate types for each application. Make i
3230 signed. Use initializers in some spots. I'll probably pay for
3232 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
3233 (scm_must_realloc): Make nm unsigned.
3234 (init_heap_seg): Make new_seg_index and n_new_objects signed.
3235 (scm_init_storage): Use prototype-style definition, and make the
3237 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
3238 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
3240 * filesys.c (scm_readlink): Make local vars rv and size ints, to
3241 avoid signed/unsigned comparison warnings, and because the return
3242 value of readlink may be -1. Don't bother casting the third
3243 argument to readlink.
3245 * filesys.c (scm_dirname, scm_basename): Move these to their own
3246 page, at the end of the file.
3247 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3249 * eval.h (scm_eval_options_interface): Add external prototype for this.
3250 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3252 * eval.c (scm_lookupcar1): Make this static.
3254 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3255 Make these prototype declarations, not K&R-style.
3257 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3258 unsigned comparison warning.
3260 * appinit.c: File removed. It had a single function in it, empty,
3261 whose reason for existence is explained in no documentation or
3262 comment. I think it's there as a default for some Tcl-style
3263 initialization, but Tcl abandoned that approach a while ago.
3264 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3265 (BUILT_SOURCES): Remove appinit.x.
3266 * Makefile.in: Regenerated.
3268 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3270 * Makefile.in: Regenerated using the last public version of
3271 automake, not the hacked Cygnus version.
3273 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3275 Remove Totoro kludge.
3276 * Makefile.in, scmconfig.h.in: Regenerated.
3277 * init.c, readline.c: Don't check if TOTORO is #defined.
3279 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3281 * Makefile.am: Adjust for new thread configuration system.
3282 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3283 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3285 (THREAD_LIBS): Definition deleted; automake will generate such
3286 things automatically.
3287 * Makefile.in: Regenerated.
3289 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3291 Simplify smob and port marking; set the mark bit in the generic
3292 marking code, and make marker routines only responsible for
3293 turning up outgoing pointers.
3294 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3295 before calling the marking function. Don't call the marking
3296 function if it's zero.
3297 * markers.c (scm_mark0): Just return #f. This function isn't
3298 necessary at all now, but it's harmless to call it. We'll leave
3299 it in so other folks' code doesn't croak at link time.
3300 (scm_markcdr): Don't call SCM_SETGC8MARK.
3301 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3302 * dynl.c (mark_dynl_obj): Same.
3303 * root.c (mark_root): Same.
3304 * srcprop.c (marksrcprops): Same.
3305 * unif.c (markra): Same.
3306 * variable.c (scm_markvar): Same.
3307 * ports.c (scm_markstream): Same.
3308 (void_port_ptob): Specify zero for our marking function.
3309 * debug.c (debugobjsmob): Same.
3310 * dynwind.c (guardsmob): Same.
3311 * filesys.c (dir_smob): Same.
3312 * fluids.c (fluid_smob): Same.
3313 * fports.c (scm_fptob, scm_pipob): Same.
3314 * mallocs.c (mallocsmob): Same.
3315 * regex-posix.c (regex_t_smob): Same.
3316 * smob.c (freecell, flob, bigob): Same.
3317 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3318 * throw.c (jbsmob, lazy_catch_funs): Same.
3320 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3322 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3323 scm_copy_tree on code in order not to let memoized code to leak
3324 out. Thus, scm_copy_tree needs to copy vectors as well since
3325 quasiquote can introduce evaluated code also inside vector
3328 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3330 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3332 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3333 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3336 * unif.c: Say that ivect and uvect are of type signed and unsigned
3337 long instead of int in commentary so that it correctly describes
3340 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3342 * stime.c: Removed declaration of strptime. (It should be
3343 declared by the system headers. If it turns out that some systems
3344 don't, we'll handle that then.) (Thanks to Greg Troxel.)
3346 * stime.h: Renamed TIMEH --> STIMEH
3348 * backtrace.c (scm_display_error, scm_display_backtrace): In order
3349 to increase portability, don't use structure assignment.
3350 (Thanks to Nicolas Neuss.)
3352 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
3354 (finalize_fd_sets): Added empty statement after last case label.
3355 (Thanks to Nicolas Neuss.)
3357 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
3360 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
3362 * init.c, readline.c: OK, I won't have these readline.x bug
3363 reports anymore. We've had them since April. The current reason
3364 is a completely unintelligible failure of totoro.red-bean.com to
3365 do the test for rl_getc_function in libreadline correctly. This
3366 kludge overrides the test if we're on totoro so that the snapshot
3367 generation process can work.
3369 * readline.c: Define a strdup replacement if not existent on system.
3371 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3373 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
3374 This change makes scm_make_vector R5RS compatible. We cannot keep
3375 the third argument since people want to be able to deduce the form
3376 of the C function call only by looking at R5RS. (At the same time
3377 we have removed some unnecessary complexity!)
3379 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
3380 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
3381 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
3382 argument in call to scm_make_vector.
3384 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3386 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
3387 This macro is useful in applications.
3389 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3391 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
3392 (scm_parse_path, scm_search_path): New Scheme level procedures.
3394 * load.h (scm_internal_parse_path, scm_parse_path,
3395 scm_search_path): Declared.
3397 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3399 * filesys.c (dirname, basename): New procedures.
3401 * init.c (scm_boot_guile_1): Removed condition around
3404 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
3405 new data type (guards) for representation of C level guards and
3406 data on the wind chain.
3407 (scm_internal_dynamic_wind): New function.
3409 * dynwind.h: Declare scm_internal_dynamic_wind.
3411 * root.h (scm_root_state): Added scm_cur_loadp.
3413 * root.c (mark_root): Added comment about cur_loadp.
3415 * load.c: #include "dynwind.h";
3416 (scm_primitive_load): Use scm_inner_dynamic_wind to update
3419 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
3421 * ports.c (current-load-port): New procedure.
3423 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3425 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
3426 not a tty, return #f.
3428 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
3429 to Julian Satchell and Roland Kaufmann.)
3431 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
3432 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
3434 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3436 * debug.h, debug.c (scm_start_stack): New function. Implements
3437 the guts of old scm_m_start_stack.
3439 * debug.c (scm_m_start_stack): Use scm_start_stack.
3441 * init.c (scm_start_stack, scm_restart_stack): Renamed to
3442 start_stack and restart_stack. (These have static scope.)
3444 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3446 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
3447 readline functions to come in release 2.3. (Thanks to Chet
3449 (handle_errors): Use the above functions.
3451 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3453 * readline.c: Improvements for readline support: Handle errors
3454 better; Implement before-read-hook.
3456 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3458 * init.c (scm_boot_guile_1), readline.c: Test for
3459 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3460 assure that we have version >= 2.1.)
3462 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3464 * readline.c (scm_readline): Defer interrupts while we're calling
3467 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3468 away the string to add_history.
3469 (completion_function): Do completion for readline. (Thanks to
3471 (scm_filename_completion_function): New procedure: Filename
3473 (current_input_getc): New function. Use this one instead of
3474 standard getc from readline.
3476 * throw.c, throw.h (scm_handle_by_throw): New function: This
3477 handler throws errors to next handler on the dynwind chain.
3479 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3481 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3484 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3486 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3488 (scm_procedure_properties): Modified to return arity together with
3490 (scm_procedure_property): Added the read-only property `arity'.
3491 (scm_set_procedure_property_x): It is an error to set the `arity'
3494 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3495 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3497 * procprop.h (scm_sym_arity): New symbol.
3499 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3500 to set the dispatch procedure of an operator or entity object.
3502 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3503 Made procedure slots read-only.
3505 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3506 scm_tcs_cons_gloc case in zero args switch; Fixed args
3507 construction for operators in scm_tcs_cons_gloc case in two args
3510 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3512 * fluids.c: Removed use of assert.h (in order to avoid
3515 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3517 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3519 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3520 change makes the evaluator safer at the cost of evaluation speed.
3521 It handles the case when the user has added a non-immediate
3522 improper end of the application form, e.g., `(+ 0 . x)'.
3523 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3524 minimize the extra cost as much as possible. The new code is
3525 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3526 problem with structs planted directly in the code (e.g. by a
3527 macro). This no longer causes segmentation fault. (Thanks to
3530 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3531 arg `proc' in order to be able to throw errors; New argument
3534 * Removed extra #include "debug.h"
3536 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3538 * scmsigs.c: Declare usleep as returning void on some systems.
3539 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3542 * coop.c (usleep): Return void on some systems.
3544 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3546 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3548 * coop.c: Changed return type of usleep to int.
3550 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3551 isn't found in the OS.
3553 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3554 isn't enabled. (Thought that I had made this change ages ago...)
3556 * iselect.c: Declare bzero if not defined by OS.
3558 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3560 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3561 condition. (Thanks to John Tobey.)
3563 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3564 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3567 * __scm.h: Start the long-term project of moving to POSIX threads.
3568 Phase 1: Classification of all critical sections.
3569 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3570 for A sections. (See comments in __scm.h for details.)
3572 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3573 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3575 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3577 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3578 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3579 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3580 dependencies on $(srcdir)/Makefile.in
3581 $(top_builddir)/config.status in order to avoid circularity.
3583 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3584 from argc if argc was 0 initially.
3586 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3587 in generation of libpath.h.
3589 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3591 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3592 libguile from 2 to 3.
3594 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3596 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3598 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3600 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3601 scm_set_port_column_x, scm_port_filename,
3602 scm_set_port_filename_x): Removed optional arguments. Added
3603 proper argument checking.
3605 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3606 stack size in machine words.
3608 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3609 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3610 to Ole Myren Röhne.)
3612 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3614 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3615 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3617 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3620 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3621 procedure apply: Copy argument lists before pushing them unto the
3622 environment so that the environment won't get mutated due to
3623 manipulation of procedure arguments. This should perhaps be
3624 regarded as a temporary solution until someone finds a more
3625 efficient one. (Thanks to Maciej Stachowiak.)
3627 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3629 * script.c (scm_compile_shell_switches): Use "guile" as default
3630 zero arg if argc is NULL.
3632 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3634 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3635 is zero. (Thanks to Dirk Herrmann.)
3637 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3639 * ports.c (scm_add_to_port_table): First line is now line 0
3640 (was 1). (Interface changed according to suggestion by Per
3643 * backtrace.c (display_header): Add 1 to line and column numbers
3644 when presenting them to the user.
3646 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3647 from debug.c --> eval.c
3649 * eval.h, eval.c (scm_eval_options_interface): New options
3651 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3652 i.e. stacks for new threads.
3654 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3656 * eval.c (unsafe_setjmp): Removed with #if 0.
3658 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3661 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3662 to avoid compiler warnings.
3664 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3666 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3668 * throw.c (handler_message): Print message on current error port
3669 instead of default error port. (Thanks to Maciej Stachowiak.)
3671 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3673 * ports.c (scm_add_to_port_table): allocate in units of
3674 struct scm_port_table *, not struct scm_port_table.
3675 * posix.c (scm_close_pipe): remove the port from the port table
3677 Thanks to Rob Engle for both fixes.
3679 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3681 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3682 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3684 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3686 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3688 * backtrace.c (display_error_body, display_backtrace_body),
3689 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3690 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3691 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3692 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3695 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3696 don't receive the jmpbuf arg anylonger.
3697 (scm_catch): Don't accept a #f tag.
3698 (scm_throw): Check that key is a symbol.
3699 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3701 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3703 * async.c (async_pending): Removed declaration.
3705 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3707 * dynwind.c (scm_wind_chain): New debug function.
3709 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3710 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3711 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3712 extra layer of functions around the body and handler of a thread.
3713 This extra layer makes sure that the handler is called in the
3714 dynamic context of the surround (= empty dynwind list), but under
3715 the *dynamic root* of the body. We can not use the dynamic root
3716 of the surround since that root belongs to another thread => stack
3717 is not handled correctly. It may seem ugly to use this extra
3718 layer, but the extra cost in terms of execution time is really
3719 negligible compared to the total amount of time required to create
3720 a thread, and it would reduce maintainability to duplicate the
3721 crucial and complicated steps performed by cwdr.
3723 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3724 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3725 get re-enabled. The important effect of this is that interrupts
3726 are blocked during thread switching so that thread data structures
3727 don't risk getting messed up by an unfortunate signal.
3728 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3729 seems to do more aggressive optimization which actually move
3730 instructions around in these macros in a fatal way. Therefore:
3731 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3732 just superstitious...)
3733 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3734 This macro should be used instead of SCM_ASYNC_TICK since the
3735 latter doesn't do context switches any more.
3737 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3738 instead of SCM_ASYNC_TICK.
3740 * coop.c, iselect.c: Since thread switches are now performed with
3741 interrupts masked, we can't use the old mechanism of delivering
3742 signals immediately when they arrive. Signals must instead be
3743 delivered when the asyncs run *after* the end of the critical
3744 section in scm_internal_select. But this also means after context
3745 switch so that the signal will be delivered to a different thread.
3746 To avoid this, I have changed the protocol of
3747 coop_wait_for_runnable_thread and friends so that they are allowed
3748 to return the original thread. So, if a signal arrives during
3749 scm_internal_select, we won't any longer be forced do a context
3750 switch, but can remain in the same thread and deliver the signal
3753 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3754 scm_asyncs_pending and made it global.
3756 * iselect.c: Small fixes.
3758 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3759 coop_condition_variable_init, coop_condition_variable_wait,
3760 coop_condition_variable_signal): Changed return type from `void'
3761 to `int'. This is to adhere closer to the pthreads interface.
3762 This, in turn, is part of an attempt to provide C versions of the
3763 mutex and condition variable primitives which can be part of a
3764 frontend to COOP or pthreads.
3766 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3767 coop_condition_variable_destroy): New functions.
3769 * coop-threads.c (scm_wait_condition_variable): Use
3770 coop_condition_variable_wait_mutex.
3772 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3773 Definitions moved to coop-defs.h.
3775 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3776 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3777 scm_cond_destroy): New C interface to mutecis and cond vars.
3779 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3781 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3783 * iselect.c: Now several threads can wait on the same file
3784 descriptor. The behaviour is compatible with OS select: All
3785 threads waiting for the fd return with the same status.
3787 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3789 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3790 Can spawn a thread from application C code.
3792 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3794 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3795 gh_doubles2scm): New functions.
3797 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3799 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3800 commented-out version of gh_eval_str()
3802 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3804 * socket.c (scm_bind): free soka after use.
3806 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3808 * stime.c (tzvar): new variable.
3809 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3810 avoid memory leaks when allocating.
3812 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3814 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3817 * gc.c, tags.h: Doc fixes.
3819 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3821 * eval.c (macro-eval!): Removed. This function was a design bug.
3822 It allowed memoized code to leak out to the scheme level. Most
3823 things that you could do with `macro-eval!' can be done with
3826 1997-12-20 Tim Pierce <twp@skepsis.com>
3828 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3829 scm_fgets now depends on ftell(3) to know how many bytes were
3832 1997-12-15 Tim Pierce <twp@skepsis.com>
3834 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3835 dealing with strings.
3837 1997-12-13 Tim Pierce <twp@skepsis.com>
3839 Make %read-line more suitable for implementing read-line efficiently.
3840 * ioext.c (scm_read_line): Strip the terminating newline from a
3841 string, and return a cons of the string and its terminator.
3843 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3844 of the string that is read is stored in this memory location.
3845 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3846 * genio.c, genio.h (scm_do_read_line): Update caller.
3847 * ports.h (scm_ptobfuns): Update typedef.
3848 * fports.c (scm_fptob, scm_pipob): Update struct.
3850 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3852 * filesys.c (set_element): Return file descriptor.
3853 (fill_select_type): Return the highest file descriptor.
3854 (scm_select): Tell select about the highest file descriptor. On
3855 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3856 Therefore the extra overhead for calculating the maximum fd seems
3857 to be more than compensated. Is this correct? In any case,
3858 scm_internal_select will be much faster with this info.
3859 (scm_select, fill_select_type, set_element): Don't accept any kind
3860 of object in the file descriptor list or vector.
3862 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3864 * iselect.c (finalize_fd_sets): Bugfix.
3866 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3868 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3869 when using scm_internal_select (since we might switch to another
3872 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3874 * simpos.c (scm_system): always define: use sysmissing if not
3875 available. Check for HAVE_SYSTEM instead of _Windows (does
3876 Windows lack system or does it have an unusable one?).
3877 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3878 Let the argument be optional: if not supplied, call system(NULL).
3880 * ports.c (scm_close_port): relax the type check from OPPORTP to
3881 PORTP; closing a closed port is allowed.
3883 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3885 * fports.c (scm_fgets): Return if the last char in a chunk is
3886 newline. When fgets returns a string whose length is `size-1', it
3887 is ambiguous whether a whole line was retrieved, so we must check
3888 explicitly whether a line terminator is present.
3890 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3892 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3893 before taking the CDR. (Thanks to Harald Meland.)
3895 * filesys.c (scm_stat): Slightly optimized.
3897 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3899 * ports.c (scm_close_port): Make sure the port is open before
3902 * guile-snarf.in: Pass args through to gcc in a way that preserves
3903 whitespace boundaries. (Thanks to Greg Badros.)
3905 1997-12-02 Tim Pierce <twp@skepsis.com>
3907 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3908 statement. (Thanks to Doug Evans for pointing this out.)
3910 1997-12-01 Tim Pierce <twp@skepsis.com>
3912 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3914 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3916 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3917 errno macro expansion of this field name. (errno is a C
3918 preprocessor macro on some systems.)
3920 1997-11-29 Tim Pierce <twp@skepsis.com>
3922 * iselect.c: Doc fix.
3924 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3926 * init.c (scm_start_stack): Removed initialization of
3927 scm_the_last_stack_var.
3929 * backtrace.h: Declare scm_the_last_stack_var.
3931 * backtrace.c: Define scm_the_last_stack_var.
3933 * root.c (mark_root): Don't mark the_last_stack_var.
3935 * root.h (scm_root_state): Removed the_last_stack_var.
3937 * throw.c: Added #include "fluids.h"
3938 (ss_handler): `the-last-stack' is now a fluid.
3940 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3941 --> the_last_stack_fluid.
3943 * backtrace.c: Added #include "fluids.h"
3944 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3945 (scm_backtrace): `the-last-stack' is now a fluid.
3947 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3948 after scm_init_fluids.
3950 1997-11-28 Tim Pierce <twp@skepsis.com>
3952 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3954 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3955 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3957 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3959 * iselect.c (coop_next_runnable_thread,
3960 coop_wait_for_runnable_thread): Disable interrupts so that no
3961 async is executed before a potential error_revive.
3962 (scm_internal_select): Disable interrupts during the parts of the
3963 code which manipulate the sleep queue and the file descriptors.
3965 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3967 * Makefile.am: Added iselect.c and iselect.h.
3969 * coop.c (coop_qinit): Initialize fields used by
3970 scm_internal_select.
3971 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3972 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3973 replacement in iselect.c.
3974 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3975 coop_join): If GUILE_ISELECT enabled, use
3976 coop_wait_for_runnable_thread instead of
3977 coop_next_runnable_thread.
3978 (usleep, sleep): New replacements for system functions if
3979 GUILE_ISELECT is enabled.
3981 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3983 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3985 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3986 iselect.h. Implement Scheme level `select' using
3987 scm_internal_select. (See NEWS.)
3989 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3991 * init.c: Call scm_init_iselect.
3993 * iselect.h, iselect.c: New files. Implements
3994 scm_internal_select. (See NEWS.)
3996 1997-11-27 Tim Pierce <twp@skepsis.com>
3998 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3999 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
4000 and scm_must_free, since ultimately the string returned will be copied
4001 by scm_makfrom0str anyway. Also, read any characters that may have
4002 been pushed onto the port with scm_ungetc.
4003 * ports.c (scm_generic_fgets): Same as for scm_fgets.
4004 * ioext.c (scm_read_line): Free string after Guilifying it.
4005 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
4007 1997-11-26 Anthony Green <green@hoser.cygnus.com>
4009 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
4011 * gh.h: Safely wrap prototypes for c++ usage.
4013 1997-11-25 Mark Galassi <rosalia@cygnus.com>
4015 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
4016 gh_repl (argc, argv).
4018 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
4020 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
4021 and to invoke scm_shell().
4022 (gh_launch_pad): took out the loading of boot-9.scm from here,
4023 since it is probably best to let the user control that. In fact,
4024 gh_repl() now invokes scm_shell() which does that.
4026 1997-11-23 Mark Galassi <rosalia@cygnus.com>
4028 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
4031 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
4033 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
4034 yesterday's underscore patch. (Thanks to Marius Vollmer for
4037 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
4039 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
4040 DLSYM_ADDS_USCORE is not defined.
4042 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
4044 * gh_data.c (gh_uniform_vector_length):
4045 (gh_uniform_vector_ref): started implementing the uniform types in
4048 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
4050 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
4051 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
4053 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
4055 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
4056 configure.in was changed).

4060 * Makefile.am (modinclude_HEADERS): Include readline.h here.
4061 * Makefile.in: Regenerated.
4063 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
4065 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
4066 OPORT is an `open' port, not an output port.
4068 * filesys.c (scm_close, set_element, get_element, scm_chown,
4069 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
4070 SCM_COERCE_OUTPORT to cope with the printstate/port magic.

4073 scm_port_column, scm_set_port_column_x, scm_port_filename,
4074 scm_set_port_filename_x, scm_port_mode,
4075 scm_close_all_ports_except, scm_set_current_output_port,
4076 scm_set_current_error_port): Likewise
4077 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
4078 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
4080 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
4081 * backtrace.c (display_backtrace_body): Likewise
4082 * fports (scm_setvbuf): Likewise

4086 * unif.c (scm_uniform_array_write): Likewise
4088 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
4090 Minor problems with substring-related tag changes.
4091 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
4092 exactly what we want to leave in to detect substrings.
4093 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
4094 * tags.h: Fix diagrams and comments describing the S tag bit;
4095 remove vestigial remarks about the D tag bit.
4096 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
4097 * strings.c: Formatting tweaks.
4099 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
4100 variable first; then SCHEME_LOAD_PATH, with a warning message.
4101 (scm_parse_path): New function.
4102 * script.c: Doc fixes.
4104 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
4106 Readline support, from Daniel Risacher.
4107 * readline.c, readline.h: New files.
4108 * init.c: #include "readline.h".
4109 (scm_boot_guile_1): Call scm_init_readline, if we have it.
4110 * Makefile.am (libguile_la_SOURCES): Include readline.c.
4111 * Makefile.in: Regenerated.
4112 * scmconfig.h.in: Regenerated, after change to ../configure.
4114 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4116 * gh.h: gh_vector_set -> gh_vector_set_x
4118 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
4120 * gh_data.c (gh_vector_set_x): changed name to make it consistent
4121 with the ! -> _x mapping when going from Scheme to C.
4123 1997-10-19 Mark Galassi <rosalia@cygnus.com>
4125 * gh.h (gh_reverse):
4133 (gh_assoc): added these gh_ functions implemented as macros.
4135 * gh_predicates.c (gh_null_p):
4136 (gh_string_equal_p): added these two missing predicates.
4138 * gh_list.c (gh_append):
4143 (gh_set_cdr_x): added these routines as I go through and try to
4144 complete the picture R4RS functions that should be mirrored in the
4147 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4149 * tags.h (scm_tc7_substring): Changed the comment and code to
4150 conform with the changes below. Folks! We have suddenly two new
4151 free tc7 codes!!! Jummy, jummy!
4153 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
4155 * Makefile.in: Rebuilt.
4156 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
4158 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
4159 * unif.c (scm_vector_set_length_x): Don't handle multibyte

4168 * hash.c (scm_hasher): Don't handle mbstrings.
4169 * gscm.c (gscm_run_scm): Don't init mbstrings module.
4170 * gc.c (scm_gc_mark): Don't handle mbstrings.
4171 (scm_gc_sweep): Likewise.
4172 * eval.c (SCM_CEVAL): Don't handle mbstrings.

4175 (SCM_TYP7D): Removed.
4176 (scm_tc7_mb_string): Removed.
4177 (scm_tc7_mb_substring): Removed.
4178 * print.c (scm_iprin1): Handle char printing directly. Don't
4180 Don't include "mbstrings.h".
4181 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
4182 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
4184 Don't include "mbstrings.h".
4185 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
4186 (SCM_SYMBOL_SLOTS): Define as 4.
4187 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
4188 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
4189 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,

4208 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
4209 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
4211 1997-10-12 Mark Galassi <rosalia@cygnus.com>
4213 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
4215 * gh_test_c.c (c_vector_test): some improvements on the vector
4218 * gh.h (gh_vector): this used to exist but do the wrong thing.
4219 Now it (almost) does the right thing, though it takes a list
4220 instead of the individual arguments. I need to see how it could
4222 (gh_list_to_vector): added this function as a macro. Corresponds
4223 to Scheme's (list->vector ...).
4224 (gh_vector_to_list): added this function as a macro. Corresponds
4225 to Scheme's (vector->list ...).
4227 * gh_data.c (gh_vector_ref): renamed from gh_vref to
4228 gh_vector_ref, so that it resembles the Scheme routines more.
4229 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
4230 resembles the Scheme routines more.
4231 (gh_make_vector): this used to be (stupidly) called gh_vector().
4232 This is the right name, since it does the same thing as the Scheme
4233 (make-vector ...) procedure.
4235 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
4237 * ports.h: #include "libguile/print.h"
4239 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
4240 Some indentation fixes.
4242 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
4243 longer a user field; New field: class_flags.
4245 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
4247 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
4249 * gh_data.c (gh_bool2scm): new function which replaces
4250 gh_int2scmb(), which is now tagged as obsolete.
4252 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
4254 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
4255 macros should by convention not test for NIMPness.)
4256 (SCM_COERCE_OPORT): Adjust indentation.
4258 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
4259 SCM_NIMP test before SCM_PRINT_STATE_P.
4261 * struct.c, struct.h, gc.c: Renamed:
4262 scm_struct_i_layout --> scm_vtable_index_layout
4263 scm_struct_i_vcell --> scm_vtable_index_vcell
4264 scm_struct_i_vtable --> scm_vtable_index_vtable
4265 scm_struct_i_printer --> scm_vtable_index_printer
4266 scm_struct_i_vtable_offset --> scm_vtable_offset_user
4268 * struct.c (scm_print_struct): Use new printer slot; Default
4269 printing: Also output hex code of vtable so that type identity
4270 will be indicated as well.
4271 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
4272 Removed struct_printer_var; Removed struct-vtable-offset;
4273 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
4274 vtable-offset-user): New constants.
4276 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
4277 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
4278 If this slot contains a procedure, use that to print structures of
4279 the type represented by this vtable.
4281 * print.c (scm_iprin1): Don't print arguments of macro
4282 transformers. (They are always: exp env.); Bugfix: Unmemoize
4283 transformer source with correct environment.
4285 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
4287 Streamlining of call-with-dynamic-root:
4289 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
4290 there is now only one catch.
4291 (cwdr_outer_body): Removed.
4292 (cwdr_handler): New function.
4293 (scm_internal_cwdr): New function to perform the function of cwdr
4294 but take args that are more useful to C code. Also, the handler
4295 is now invoked *outside* of the new dynamic root, like the docs
4296 say. We no longer have to catch absolutely all errors, the caller
4297 is responsible for using a handler that does not throw, if he
4299 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4300 * root.h (scm_internal_cwdr): New prototype.
4302 Even more but risky streamlining:
4304 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4305 allocation of the jumpbuf of a root continuation. The changes
4306 below are controlled by it. They are now deactivated.
4307 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4308 the JMPBUF of the scm_rootcont to NULL before returning.
4310 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4311 when they are non-NULL.
4312 (scm_gc_mark): Likewise, mark only when non-NULL.
4314 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
4315 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
4317 * gc.c (scm_done_malloc): New function.
4318 gc.h (scm_done_malloc): New prototype.
4320 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
4321 (struct scm_print_state) [revealed]: New field.

4323 type checking purposes.
4324 (scm_valid_oport_value_p): New prototype.
4326 * print.c (scm_valid_oport_value_p): New function to check whether
4327 a certain value is acceptable as a port argument.
4328 (scm_print_state_vtable): New variable.
4329 (scm_free_print_state): Set `revealed' field to false.
4330 (scm_iprin1): Call user supplied closure printer with
4331 scm_printer_apply. Print in the traditional way when there isn't
4332 one or when it returns #f.
4333 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4334 Accept a port/print-state pair in addition to just a port.
4335 (scm_prin1): Don't return the print_state to the pool when it has
4337 (scm_printer_apply): Set `revealed' field of print_state to true.
4338 (scm_init_print): Set scm_print_state_vtable.
4339 (print_state_fluid, print_state_fluid_num): Removed.
4341 * throw.h (scm_handle_by_proc_catching_all): New prototype
4342 throw.c (scm_handle_by_proc_catching_all): New function
4344 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
4346 * Makefile.in: Regenerated with automake 1.2c.
4348 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
4350 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
4351 was looping endlessly.
4353 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
4355 * strports.c (scm_eval_string): Don't close the port.
4357 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
4358 former returns a nice normal integer. (Thanks to Daniel
4361 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
4363 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
4364 makefile variable as a build parameter called LIBS. The
4365 build-guile program will use this, for the time being.
4366 * Makefile.in: Regenerated.
4368 Thanks to Shiro Kawai:
4369 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
4370 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
4373 * Makefile.in: Regenerated with automake 1.2a.
4375 * script.c (scm_compile_shell_switches): If we hit the -c or --
4376 arguments, don't set the car of (command-line) to scm_usage_name,
4377 the prettified name of the guile executable; give it the full
4378 path, the way shells usually handle $0.
4380 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4382 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
4383 Scheme-level name `array-map' and renamed `serial-array-map' to
4384 `serial-array-map!'.
4386 * backtrace.c: Introduced exception handlers which now enclose
4387 `display-error' and `display-backtrace' so that error reporting
4388 won't get into infinite loops if an error occurs during displaying
4389 of the error. This can very easily happen with user supplied
4390 print call-back routines.
4392 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4394 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
4395 the names `serial-array-map' and `array-map' should be removed.)
4397 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
4399 * init.c (scm_boot_guile_1): Added scm_init_objects ().
4400 Added #include "objects.h"
4402 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
4403 Add #include "feature.h".
4405 * Makefile.am (libguile_la_SOURCES): Added objects.c.
4406 (modinclude_HEADERS): Added objects.h.
4408 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
4409 This test is needed at many places in the code and should be
4410 abstracted. (Motivated by the need of this test in libguiletk.)
4412 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
4413 (scm_eval_string), load.c (scm_primitive_load,
4414 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
4415 Use SCM_EOF_OBJECT_P.
4417 * eval.c (scm_init_eval): Add feature `delay'.
4419 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4421 * scmhob.h: Removed.
4423 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4425 * list.h (SCM_LISTn): New macros. Make list creation in C code
4426 prettier. The idea comes from STk.
4428 * sequences.h, sequences.c, append.h, append.c: Removed. These
4429 files implemented non-R4RS operations which would encourage
4430 non-portable programming style and less easy-to-read code.
4432 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
4435 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
4436 sequences.h, #include append.h.
4438 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
4441 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
4443 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
4445 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
4447 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4449 * eval.c: Added #include "objects.h"
4451 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
4454 * smob.c (scm_smob_prehistory): Create two objectsmobs with
4455 adjacent smob numbers.
4457 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4459 * procprop.h: Added declaration of scm_i_inner_name.
4461 * gsubr.c: New global symbol scm_i_inner_name.
4463 * debug.c (scm_procedure_name): Try procedure property
4464 `inner-name' if `name' fails.
4466 * print.c (scm_iprin1): Use scm_macro_name.
4468 * eval.c (scm_m_define): Give names to macros as well; Only the
4469 first top-level definition gives a procedure/macro a name.
4470 Otherwise confusing names can turn up in backtraces.
4471 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4472 `name'; Give names to macros as well.
4474 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4475 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4478 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4480 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4482 (prinmacro): Removed. The code has been moved/merged into print.c
4483 in order to decrease code redundancy. We want macros to print in
4484 a way equivalent to procedures, and it would be silly to duplicate
4485 the required code. (We don't want to maintain two places.)
4486 (macrosmob): Print field is now a NULL pointer.
4488 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4489 scm_macro_transformer): New prototypes.
4490 (scm_tc16_macro): Declared.
4492 * print.c (scm_iprin1): Added code for printing of macros. Macros
4493 are now printed in a way equivalent to procedures.
4495 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4497 * procs.h (scm_closure_p): Added declaration.
4499 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4501 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4502 Shouldn't pass "heap" as the subr name.
4504 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4506 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4507 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4508 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4509 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4510 SCM_BOOL_T. Any non-false value is true.
4512 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4514 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4515 scm_gensym): Added prototypes.
4517 * symbols.c (scm_gensym): New function. This will speed up
4518 certain types of applications (such as macro systems) which
4519 generate lots of symbols.

4535 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4537 * Makefile.in: Regenerated, so it uses "tar", not "gtar".

4564 * list.c (scm_list_append_x): Allow non-pair as last argument.
4565 This is consistent with the R4RS append and is probably the
4566 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4568 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>

4588 third argument is now optional.
4590 * posix.c (scm_execl, scm_execlp): make the filename argument
4591 compulsory, since omitting it causes SEGV.
4592 (scm_sync): return unspecified instead of #f.
4593 (scm_execle): new procedure.
4594 (environ_list_to_c): new procedure.
4595 (scm_environ): use environ_list_to_c. disable interrupts.

4597 improve error checking.
4599 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4601 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4602 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4603 argument to SCM_ASSERT. Furthermore, the name of the function
4604 should be passed as first argument when signalling
4605 SCM_WNA. (Thanks to Thomas Morgan)
4607 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4608 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4609 dispatches on the number of actual args has a default case
4610 reporting an internal error. This is a vestige from a version
4611 that mallocated a SCM vector to hold the arguments. In the
4612 current version this check is too late: if it ever happens we will
4613 have already overstepped the bounds of the array.
4615 Also, the patch [...] adds a check for too many actual arguments."
4617 mdj: Removed check for "internal programming error".
4619 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4621 * gh_io.c (gh_write): New function.
4623 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
4624 throw.c (scm_internal_stack_catch): New sibling to the other catch
4625 functions. Code moved from gh_eval.c.
4626 throw.h: Added header.

4636 fold in the functionality of scm_primitive_dup.
4637 (scm_primitive_dup): deleted.
4639 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
4641 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
4642 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
4643 ultrix are defined. Use setvbuf instead of setbuf.
4644 (scm_setvbuf): new procedure.
4645 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
4646 (scm_setfileno): moved from ioext.c.

4660 (scm_init_print): Initialize them.
4661 (scm_iprin): If print_state_fluid carries a print_state, use that
4662 instead of creating a new one.

4664 definitions to help with calling printer functions written in
4666 * print.h (scm_printer_apply): New prototype.

4682 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4684 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied

4709 stream has been set.
4710 (scm_duplicate_port): deleted, there's now an implementation in

4763 data. (dynl_smob): Use it.
4764 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4765 the dynamic object data below the linking of the object to avoid
4766 memory leak when the linking code throws an error. Now the code
4767 leaks a whole dynamically linked library when must_malloc throws,
4768 but that should be much less likely.
4770 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4772 Changes to compile under gnu-win32, from Marcus Daniels:

4810 think this is left over from the (eq? '() #f) days.
4812 * read.c (recsexpr): Give this a dummy definition if
4813 DEBUG_EXTENSIONS isn't #defined.
4815 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>

4843 turn off REG_EXTENDED.
4844 (scm_init_regex_posix): New regexp/basic symbol.
4845 (REG_BASIC): #define this if it is not already present.

4892 (cwdr_outer_body): New function, to establish the user's handler,
4893 and pass control to cwdr_inner_body.

4905 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4906 the feeling that real thread systems will not need this...
4908 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4910 Try to detect when people are using one version of libguile and a

4922 primitive definitions under their Scheme names.
4924 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4925 1:2. Helps avoid confusion between installed and uninstalled libs.
4927 * scmconfig.h.in: Regenerated. (Needed after June 3 change to

4950 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4952 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA

4956 * tag.c (scm_tag): Remove unreachable statement.
4957 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4958 top of the word, it should be unsigned.
4960 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4961 is defined, to avoid warnings; it's only used in the
4962 conflict-checking code. Which might go away anyway.
4963 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4964 conditionals; put the label definition in an #if too, to stifle
4967 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4968 ChangeLog-threads in the distribution.
4969 * Makefile.in: Regenerated.

4979 * load.c (scm_init_load_path): Append $(datadir)/guile to

4985 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
4986 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
4987 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
4988 call the sysdep functions with deferred ints.
4989 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
4990 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
4991 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
4994 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
4997 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
4999 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
5001 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
5003 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
5006 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
5008 * eval.c (scm_lookupcar1): New procedure to cope with a race
5009 condition during lookup (when using threads).
5010 (scm_lookupcar): Implement in terms of scm_lookupcar1.
5011 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
5014 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
5016 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
5017 supplied. (Change from Tim Pierce.)
5019 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
5021 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
5022 23:47:01 1997" changelog: Slots are now initialized with `#f' by
5023 default and not `()'. `#f' is the canonical non-value in Scheme,
5026 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5028 * struct.c (struct_printer): New variable that holds a handle on
5029 the Scheme variable *struct-printer*. This variable can be set by
5030 Scheme code to override the printing of structures.
5031 (scm_print_struct): If struct_printer is set, call it. If it is
5032 not set, or returns #f, print the structure in the old fashion.
5033 Include "eval.h" for scm_apply.
5035 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
5037 * struct.c (scm_struct_ref, scm_struct_set_x): Use
5038 scm_struct_i_n_words to get the number of fields, not
5039 -scm_struct_n_extra_words.
5041 On the route to fancier struct printing:
5042 * struct.c (scm_print_struct): New function to print a structure.
5043 Include "genio.h" to support it. This function doesn't do
5044 anything interesting right now, but I think it should be here
5046 * struct.h: Include "print.h" and add prototype for
5048 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
5049 print structures ourself.
5051 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5053 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
5054 before applying the handler in case it doesn't return.
5056 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
5058 * scmsigs.h, async.h: updated.
5060 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
5063 * posix.c (scm_uname): interpret only negative values as an error.
5064 Solaris normally returns a positive value.
5066 * script.c (scm_compile_shell_switches): if we are not going into
5067 an interactive repl, set scm_mask_ints to zero so that asyncs can
5070 * simpos.c (scm_system): don't ignore/unignore signals around
5073 * posix.c (scm_open_pipe): don't ignore/unignore signals around
5076 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
5077 done in boot-9.scm instead.
5079 * scmsigs.c, async.c: Major rewriting of signal handling code.
5080 (scm_sigaction): new procedure.
5081 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
5083 (scm_raise): return unspecified, throw error on failure.
5085 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5087 * regex-posix.c (scm_init_regex_posix): Register the "regex"
5088 feature, to help boot-9.scm decide whether to import the regex
5091 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5093 * eval.c: Include scmconfig.h at the beginning of the file so that
5094 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
5097 * regex-posix.c: #include "_scm.h" before conditionally #including
5098 <regex.h>; the former defines HAVE_REGCOMP.
5100 * regex-posix.c: #include <regex.h> conditionally, so the file is
5101 CPP'able (for dependency scanning) even on systems that don't have
5104 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5106 Add new R4RS-compliant syntax for keywords.
5107 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
5108 regardless of the setting of the `keywords' read option.
5109 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
5110 can be re-read no matter what the setting of the `keywords' read
5113 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
5115 Add support for POSIX regular expressions.
5117 * regex-posix.c, regex-posix.h: New files. (Some code
5118 is taken liberally from rx/rgx.c in the old Guile dist.)
5120 * init.c: Include regex-posix.h.
5121 (scm_boot_guile_1): Call scm_init_regex_posix.
5123 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
5124 Add regex-posix.[ch] sources.
5125 * Makefile.in: Regenerated.
5127 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
5128 to do this automatically? It didn't for me, bleh.)
5130 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
5132 * fports.c (print_pipe_port): New function.
5133 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
5134 latter doesn't even take the right arguments.
5136 * Makefile.am: Increment shared lib revision number. I think
5137 sometimes the uninstalled Guile finds the installed shared lib;
5138 Gord says doing this might help. As things turned out, I can't
5139 say whether it does.
5140 * Makefile.in: Regenerated.
5142 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
5143 passing it as the closure argument to scm_boot_guile. (Bill
5146 * ports.c (print_void_port, putc_void_port, puts_void_port,
5147 write_void_port, flush_void_port, getc_void_port, close_void_port,
5148 noop0): Use ANSI prototypes instead of K&R declarations, so the
5149 initialization of void_port_ptob gets aggressively type-checked.
5150 Fix arguments of print_void_port and write_void_port. (Bill

5184 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
5186 * script.c (scm_find_executable): Use prototype-style definition
5187 here; apparently it's not quite right to have const in a prototype
5188 and then use a K&R declaration. I wonder if stuff like this will
5189 go away if we compile with -Wrequire-prototypes, or whatever that
5190 is... (Bernard URBAN)
5192 * scmhob.h: New text from Bernard URBAN.
5194 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
5196 * script.c: Don't #define const on hpux. Configure takes care of
5197 this. (Thanks to Larry Schwimmer.)
5199 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
5200 decide whether to #include <unistd.h>, instead of listing a bunch
5201 of systems. Don't #include stdio twice. Removed dyked-out
5202 definition of scm_find_impl_file.
5204 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5206 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
5207 library version info to 1:0.
5208 * Makefile.in: Regenerated.

5214 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
5215 throw.c: Update copyright years; these files have been worked on
5216 significantly in 1997, but only had copyright years for 1996.
5217 Also, change name of copyright holder on some from Mikael
5218 Djurfeldt to Free Software Foundation; he has signed papers
5219 assigning the changes to the FSF.
5221 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
5222 reason not to give the user the option.
5224 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5225 Return #f on end-of-file when scanning table (i.e. when called
5226 with no arguments). Try to catch errors, when we can.
5227 * posix.c (scm_getgrgid, scm_getpwuid): Same.
5229 * script.h (scm_shell_usage, scm_compile_shell_switches): New
5230 external declarations. These are useful.
5232 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
5234 * posix.c: don't include <sys/select.h> or define macros for
5235 select, since they were not used in this file.
5237 * filesys.c (scm_select): make the fifth parameter microseconds,
5238 not milliseconds. let the fourth parameter be either a real value
5239 or an integer or #f. The first, second and third arguments can
5240 now be vectors: the type of the corresponding return set will be
5242 (set_element, get_element): new static procedures.
5244 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5246 * strports.c (scm_eval_string): New function.
5247 (scm_eval_0str): Trivially re-implemented in terms of
5249 * strports.h (scm_eval_string): New extern decl.
5251 * net_db.c (h_errno): Add extern decl for this.
5253 * fports.c (local_pclose): New function.
5254 (scm_pipob): Use it in the initializer here.
5257 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5258 Use a meaningful error message when signalling an error. For
5259 this, scm_gethost must check h_errno rather than errno.
5261 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5263 * Makefile.in: Regenerated, using automake-1.1p.
5265 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
5267 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5268 not SCM_UNSPECIFIED.
5270 * script.c (scm_compile_shell_switches): don't append (quit) if
5272 (scm_shell): call scm_exit_status and exit on the result of the
5275 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5277 Ensure that shared substrings are handled properly when passed to
5278 a system call or other foreign function. Many thanks to Tim
5280 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5281 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5282 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5283 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

5285 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
5286 (scm_display_error_message): use RO macros when strings may be RO.
5287 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
5288 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
5289 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c

5294 scm_strftime), vports.c (scm_make_soft_port): use
5295 SCM_COERCE_SUBSTR to make sure shared substrings are
5298 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5300 * error.c (scm_error): Add newline to error message.
5302 * init.c (scm_init_standard_ports): Doc fix.
5304 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5306 * dynl-shl.c: Completely replaced with new code from Bernard
5309 * script.c (scm_ice_9_already_loaded): New variable.
5310 (scm_compile_shell_switches): Use it.
5312 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5314 * filesys.c (scm_input_waiting_p): add missing third argument to
5317 * stime.c (scm_localtime): copy the result of localtime before
5318 calling gmtime in case they share a buffer.
5319 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5322 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5324 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5326 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5328 * Makefile.am (check-local): New target, which causes 'make check'
5329 to run gh_test_c and gh_test_repl, with some trivial input.
5330 * Makefile.in: Rgnrtd.
5332 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5334 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5337 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
5339 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
5340 sure how this was supposed to work.
5341 (scm_async_click): don't send SCM_TICK_SIGNAL.
5342 (scm_init_async): don't initialize %tick-thunk.
5344 * the following change doesn't affect the Scheme interface:
5345 gc-thunk is called at the end of garbage collection. however it's
5346 no longer implemented by pretending it's a signal.
5348 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
5349 system async corresponding to scm_gc_thunk.
5350 * async.h: declare scm_gc_async.
5351 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
5352 gc-thunk directly, instead of going through a signal handler.
5353 (scm_gc_async): new variable, points to the GC system-async.
5354 (scm_init_async): save the GC async as scm_gc_async instead
5355 of using system_signal_asyncs.
5356 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
5358 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
5360 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
5361 Don't screw up if we're interrupted.
5362 * Makefile.in: Regeneradet.
5364 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
5366 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
5368 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
5369 we're not using AM_INIT_GUILE_MODULE any more.
5370 * Makefile.in: Reneregated.
5372 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5374 Functions for finding variable bindings, grace à Tim Pierce.
5375 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
5376 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
5378 Get 'make dist' to work again.
5379 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
5380 * Makefile.in: Regenerated, like a surry without a fringe on top.
5382 Changes for reduced Guile distribution: one configure script,
5384 * configure.in, configure: Removed.
5385 * acconfig.h, acinclude.m4: Moved to parent directory, where the
5386 real configure script lives.
5387 * Makefile.in, scmconfig.h.in: Regenerated.
5389 * init.c: #include "script.h", to get prototype for script.c's
5392 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
5394 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
5395 scm_must_malloc, not raw malloc.
5397 * script.c (scm_compile_shell_switches): Dyke out debugging output
5400 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5402 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
5404 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
5405 system has them. Hope this is safe. Previously
5406 sys/timeb.h was included if HAVE_FTIME was defined or if
5407 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
5408 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
5410 * ioext.c (scm_setfileno): add missing third argument to
5411 scm_misc_error call.
5413 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
5415 * eq.c (scm_equal_p): Correctly compare strings of different
5416 varieties. (Thanks to Tim Pierce.)
5418 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
5420 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
5421 #! block comment must occur on a line all by itself.
5423 Move most of the guts of shell command processing into libguile,
5424 so guile.c can be very small (and eventuallly auto-generated. (I
5425 mean, generated mechanically, not self-generated. Hmm.))
5426 * guile.c, script.c, script.h: New source files.
5427 * init.c (scm_boot_guile_1): Call scm_init_script.
5428 * libguile.h: #include "script.h".
5429 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
5430 targets, for new executable.
5431 (libguile_la_SOURCES): Mention script.c.
5432 (modinclude_HEADERS): Add script.h.
5433 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
5434 not dynamic linking is enabled. This is because we're generating
5435 executables now. Move CY_AC_WITH_THREADS call after those, so the
5436 values of cy_cv_threads_libs captures the libs chosen above.
5437 * Makefile.in, configure, aclocal.m4: Regenerated.
5439 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
5440 We don't maintain this interface any more, and it just confuses
5443 * alloca.c: #include <scmconfig.h>, not <config.h>.
5444 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
5445 it'll get included in disties.
5447 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5449 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
5450 be distributed, because they confuse people.
5451 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
5453 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
5455 * configure.in: check for presence of gethostent (not present on
5456 OpenBSD by default).
5457 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
5458 * configure, scmconfig.h.in: Regenerated.
5460 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5462 * backtrace.c (scm_backtrace): Split message string across
5463 newlines properly. GCC is more tolerant of this than other
5466 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
5468 Merge threads directory into libguile.
5469 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5470 threads.h: New source files.

5474 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5475 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5476 coop-threads.c.cygnus, coop-threads.h.cygnus.
5477 * configure.in: If we're using threads, include threads.o in
5479 * _scm.h, libguile.h: threads.h lives in this directory now.
5480 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5481 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5482 currently used, but brought along for information's sake.
5483 * ChangeLog-threads: log from old 'threads' directory.
5484 * Makefile.in, configure: Rebuilt.
5486 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5488 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5491 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5493 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5495 Merge GH interface library into libguile.
5496 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
5497 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5498 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5499 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5501 (EXTRA_libguile_la_SOURCES): ... here.
5502 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5503 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5504 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5505 New variables, describing how to build the gh test programs.
5506 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5507 build the test programs, and we probably should have been linking
5508 libguile.la against them all along, to support AIX shared libs.
5509 Add cflags for threads to CFLAGS; add libs for threads to new
5510 variable THREAD_LIBS, used in Makefile.am.
5511 * ChangeLog-gh: log from old `gh' subdirectory.
5512 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5514 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5516 * acconfig.h: Undo change of Apr 9; including the definition of
5517 PACKAGE in the guile headers conflicts with applications' own
5519 * scmconfig.h.in: Regenerated.
5521 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

5528 when PROC is receiving no arguments.
5530 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5532 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5533 have S_IFSOCK. This is the case under Ultrix.
5535 * posix.c (scm_status_exit_val, scm_status_exit_val,
5536 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5537 Ultrix versions of WIFSTOPPED, etc., which assume that their
5538 arguments are lvalues (hmm).
5540 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5542 * eval.c: Doc fixes.
5544 * throw.c: Doc fixes; rearranged.
5546 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
5548 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
5550 * acconfig.h: Added entry for PACKAGE.
5551 * scmconfig.h.in: Regenerated.
5553 Changes to work with automake-1.1n, which has better libtool support.
5554 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5555 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5557 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5559 * Makefile.in: Rebuild.
5561 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5563 * stime.c (scm_mktime): take an optional zone argument.
5564 (scm_localtime): check putenv return value.
5565 (scm_strftime, scm_strptime): moved from posix.c. move #include
5567 stime.h, posix.h: update prototypes.
5568 (bdtime2c, setzone, restorezone): new static procedures.
5569 (scm_mktime, scm_strftime): use them.
5570 (scm_strftime): don't call mktime before strftime. Use
5571 filltime for return value.
5572 (filltime): convert NULL zname to #f.
5573 (scm_strptime): return a count of characters consumed, not
5574 the remaining string.
5576 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5578 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
5579 (scm_mktime): likewise.
5581 Uncomment localtime and mktime.
5583 * configure.in: add AC_STRUCT_TIMEZONE.
5585 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5587 * stime.c (scm_init_stime): don't define ticks/sec.
5588 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5589 return value problem and is still portable.)
5591 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5593 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5594 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5595 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5596 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5597 cpp_err_symbols.c): Corresponding changes.
5598 * Makefile.in: Regenerated.
5600 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5602 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5603 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5604 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5605 * putenv.c: new file, from sh-utils 1.12.
5607 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5608 since allocation isn't for Scheme objects.
5609 (scm_putenv): copy strings before placing in the environment.
5611 * stime.c (scm_current_time): throw an error if time returns -1,
5612 instead of returning #f.
5613 (scm_get_internal_real_time, scm_get_internal_real_time): use
5614 scm_long2num for return value instead of SCM_MAKINUM.
5616 * stime.h: prototypes updated.
5618 * stime.c (scm_time_in_msec): apparently unused, deleted.
5620 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5622 * configure.in: check for gettimeofday.
5624 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5625 which may be more usefully portable than a gettimeofday interface.
5627 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5629 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5631 * Makefile.in: Regenerated.
5633 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5635 * stime.c (filltime): recovered static procedure.
5636 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5639 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5640 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5642 * posix.c (scm_mknod): split the mode argument into type and perms
5643 arguments, like the extra fields returned by stat.
5645 * fports.c (scm_pipob): set the close, free and print procedures.
5646 (scm_close_pipe): new procedure.
5648 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5649 define them in boot-9.scm
5651 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5653 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5654 wan't defined. Don't include fd.h.
5656 * Previously fd.h was regenerated whenever configure was run,
5657 forcing a couple of files to be recompiled.
5659 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5660 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5661 Check for _fileno as well as _file.
5663 * ioext.c: don't fd.h.
5664 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5667 * Change the stratigy for getting information about errno
5668 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5669 generating lists of symbols during the build process, which will
5670 not always work, include comprehensive lists in the distribution.
5671 To help keep the lists up to date, the "check_signals" and
5672 "check_errnos" make targets can be used.
5674 * configure.in: don't check for a command to extract errno codes.
5675 * Makefile.am: update file lists, remove errnos.list and errnos.c
5676 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5677 check_errnos targets.
5678 (CLEANFILES): remove errnos.c and errnos.list, add
5679 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5680 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5681 * errnos.default: deleted.
5682 * cpp_signal.c: new file.
5683 * cpp_errno.c: renamed from errnos_get.c.
5684 * cpp_err_symbols, cpp_sig_symbols: new files.
5685 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5686 * error.c (scm_init_error): #include cpp_err_symbols instead of
5688 * posix.c (scm_init_posix): don't intern signal symbols. #include
5691 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5693 * strop.c (scm_i_index): allow the lower bound to be equal to the
5694 length of the string, so a null string doesn't always give an error.
5696 * posix.h: new prototypes.
5697 * posix.c (scm_status_exit_val, scm_status_term_sig,
5698 scm_status_stop_sig): new functions, as in scsh. They break down
5699 process status values as returned by waitpid.
5701 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5703 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5704 configure doesn't know about it.
5706 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5708 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5710 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5711 which defines C variables with global linkage.
5713 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5715 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5718 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5720 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5721 has time to check why this doesn't work well with continuations.
5723 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5725 * Fix shell syntax error; some shells won't tolerate
5726 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5728 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5730 * posix.c (scm_uname): throw an error if uname fails instead
5733 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5735 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
5738 * async.c (scm_ints_disabled): definition moved from error.c.
5740 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5742 * acconfig.h: Removed PACKAGE.
5744 * scmconfig.h.in: Regenerated.
5746 * snarf.h: g++ says it's non-portable not to specify the first
5747 argument in a varargs declaration. I introduced the first
5748 argument by using preprocessor conditionals.
5750 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5752 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5753 (scm_freopen): use RO string macros for filename and modes.
5754 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
5756 * posix.c (scm_getgrgid): simplify conversion of name to C string.
5757 (scm_mknod): use RO string macros for path.
5759 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
5760 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5762 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5763 use SCM_ROSTRINGP and SCM_ROCHARS.
5765 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5767 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5770 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5771 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5772 support for byte vectors.
5774 * print.c (scm_iprin1): Limit number of vector elements printed
5775 according to pstate->length.
5777 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5779 * backtrace.c (scm_display_error_message): don't segv if message
5782 * error.h: prototype for scm_error_scm.
5784 * error.c (scm_error_scm): new procedure, reimplements scm-error
5785 in C and uses scm_error.
5787 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5789 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5790 pointer to the Scheme variable read-hash-procedures and intern it
5791 in scm_init_read. Modify scm_read_hash_extend and
5792 scm_get_hash_procedure to use the pointer.
5794 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5796 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5797 (SCM_KEYWORD_STYLE): defined.
5799 * read.c (scm_read_opts): add a keywords option. This isn't a
5800 boolean option, in case someone wants to add support for DSSSL
5802 Setup scm_keyword_prefix symbol.
5803 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5805 I've left keyword support disabled by default, since it doesn't
5806 seem to break the module system and it gives R4RS standard behaviour.
5807 It can be reactivated with (read-set! keywords 'prefix).
5809 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5811 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5812 before constructing arbiter.
5814 * eval.c (scm_m_define): Bugfix: Check that the object is a
5815 closure before setting the procedure property!
5817 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5819 * ports.c: Removed `ungetc-char-ready?'.
5821 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5823 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5824 (idea from Mikael: make it a pair so scm_permanent object only
5826 (scm_read_hash_extend): don't call scm_permanent_object.
5827 (ideas from Mikael): if chr is already in the list, replace its
5828 procedure instead of appending it again. If proc is #f, remove
5830 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5832 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5834 * gdbint.c (gdb_read): update scm_lreadr usage.
5836 * load.h: update prototypes.
5838 * load.c (scm_primitive_load, scm_read_and_eval_x,
5839 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
5841 * read.h: add prototype for scm_read_hash_extend. Change args for
5844 * read.c (scm_read_hash_procedures): new variable.
5845 (scm_read_hash_extend): new procedure.
5846 (scm_get_hash_procedure): new procedure.
5847 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5848 for extended # processing.
5849 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5850 scm_read_token): remove case_i, sharp arguments. Change callers.
5852 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5854 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5855 (SCM_CASE_INSENSITIVE_P): define.
5857 * read.c: add case-insensitive option to scm_read_opts.
5858 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5859 to determine whether to convert symbol case.
5860 (default_case_i): definition removed.
5861 * read.c (scm_read_token): if case_i, downcase ic before doing
5864 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5866 * configure.in: Added configuration option `guile-debug'.
5867 Configure with --enable-guile-debug if you want a bunch of extra
5868 functions used for debugging when developing Guile.
5870 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5872 * procs.c (make-cclo): New undocumented debugging procedure: Make
5873 compiled closure with internal procedure PROC and length LENGTH.
5874 Only compiled if GUILE_DEBUG is defined.
5876 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5878 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5880 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5882 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5883 with 3 or more args internally to the evaluator.
5885 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5887 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5888 with 3 or more args internally to the evaluator. This is mainly
5889 because we don't want to pass entry and exit points of the
5890 debug support twice, but it also seems to increase the speed of
5891 the evaluator for such calls (e. g. (+ 1 2 3)).
5893 * backtrace.c (scm_display_application): New procedure:
5894 display-application; Set fancy printing parameters individually
5895 for different types of display (backtrace, error, application).
5896 (These should of course be customizable!)
5898 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5899 clear the CHECK-flags.
5901 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5903 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5905 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5907 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5908 from pairs with a GLOC in the car.
5910 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5911 otherwise `symbol-hash' will behave badly.
5912 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5913 we get segmentation fault!
5915 * symbols.c: Added #include "weaks.h". New functions:
5916 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5917 moved to an extraneous library when we split libguile.)
5919 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5921 * filesys.c (scm_stat): stat now takes fport arguments too as
5922 documented in the manual.
5924 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5926 * debug.c (scm_single_step): Bugfix: Call continuation with
5927 scm_call_continuation instead of throwing to it.
5929 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5931 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5932 argument wasn't declared to be optional.
5934 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5936 * stime.c (scm_init_stime): Add feature "current-time".
5938 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5940 * throw.h: prototype for scm_exit_status.
5941 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5942 args to derive an exit status. Allows (quit) to work from a
5944 (scm_exit_status): new function.
5947 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5949 * eval.c (scm_deval): Removed some old code.
5950 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5952 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5955 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5958 * procs.c: Introduce the existent C function scm_thunk_p at the
5959 Scheme level as well.
5961 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5963 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5964 used from C to easily lookup the value of a symbol in the current
5967 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5969 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5970 scm_init_unif in this file. This will also fix a previous problem
5973 * configure.in: Added AM_MAINTAINER_MODE
5975 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5977 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5980 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5982 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5983 source files that are not always included in libguile but should
5984 have their dependencies calculated by automake. This variable is
5985 recognized by automake, no further magic is needed.
5986 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5987 to deal exclusively with *.lo files, as it seems. The *.o files
5988 are built automatically when the corresponding *.lo file gets
5991 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5993 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5996 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5998 * unif.c (scm_array_set_x): minor change to argument error checking.
6000 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
6002 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
6003 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
6004 They should only be included in the library at configure.in's
6006 (libguile_la_LDADD): Include the appropriate .lo files here.
6007 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
6008 so we know when to build them (and their .lo bretheren).
6009 * configure.in (LIBLOBJS): New substituted variable. We let
6010 configure decide which .o files to include in LIBOBJS, and then
6011 put the corresponding list of .lo files in LIBLOBJS. The latter
6012 is what we pass to libtool.
6013 * Makefile.in, configure: regenerated.
6015 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
6017 * symbols.c (scm_sysintern0): New function. Contains the core of
6018 old scm_sysintern but doesn't take a second value argument.
6019 (scm_sysintern): Now uses scm_sysintern0.
6020 (scm_sysintern_no_module_lookup): Renamed to
6021 scm_sysintern0_no_module_lookup and doesn't take a second value
6022 argument any longer.
6024 * symbols.h (scm_sysintern0: Added declaration.
6026 * options.c (scm_init_opts): Use scm_sysintern0 instead of
6027 scm_sysintern when interning option keys. Otherwise we risk
6028 destroying the values of already interned variables.
6030 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
6031 scheme-level boolean (use SCM_NFALSEP).
6033 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
6035 (scm_backtrace): New function. (C version of old function from
6036 boot-9.scm) Motivation: Make it possible to display backtraces
6037 without depending on boot-9.scm. (I'm uncertain if this
6038 motivation is good enough...)
6040 * root.h (scm_root_state): Add member the_last_stack_var.
6041 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
6043 * root.c (mark_root): Mark scm_the_last_stack_var.
6045 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
6048 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
6050 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
6051 1. mark_lazy_catch didn't mark the smob.
6052 2. Both functions above have standard variants:
6053 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
6054 free_lazy_catch --> scm_free0.
6056 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
6058 * throw.c (scm_internal_lazy_catch): New function.
6059 (scm_lazy_catch): Rewritten to use it.
6060 (scm_ithrow): Handle the new lazy catch representation.
6061 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
6062 that doesn't have a jmpbuf is a lazy catch clause.
6063 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
6064 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
6065 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
6067 (scm_init_throw): Register the new lazy-catch smob type.
6068 * throw.h (scm_internal_lazy_catch): decl for new function.
6070 * throw.c (scm_internal_catch): Doc fixes.
6072 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
6073 configure.in. Including this might cause problems if applications
6074 that link against libguile include their own copies of alloca, but
6075 if they're using autoconf, they should be adding libguile to LIBS
6076 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
6077 the copy in libguile, and things will be okay. (I think.)
6079 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6081 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
6083 strop.h: move prototypes too.
6085 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
6087 * posix.c (scm_init_posix): don't intern EINTR since it's now done
6090 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
6091 etc. I deleted them from filesys.c long ago, but didn't
6092 notice they were here too (although ineffective since
6093 sys/stat.h wasn't included).
6095 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
6097 * eval.c: Don't define alloca in GCC case. gcc will automatically
6098 use __builtin_alloca if appropriate.
6100 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
6102 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
6103 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
6104 that values of automatic variables are preserved. See comments
6105 for safe_setjmp for details.
6107 Change from Thomas Morgan:
6108 * variable.c: Include eq.h.
6109 (var_equal): New function.
6110 (variable_smob): Use var_equal as the discriminator for variables.
6112 * throw.c (s_throw): Remove extraneous declaration.
6114 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
6115 * eval.c: Add necessary CPP cruft to support that.
6116 * configure, Makefile.in, scmconfig.h.in: regenerated.
6118 Change from Thomas Morgan:
6119 * procprop.c (scm_procedure_properties): Convert the Scheme
6120 boolean returned by scm_procedure_p into a C boolean before using
6121 it as a condition for SCM_ASSERT.
6122 (scm_procedure_property): Likewise.
6124 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
6125 indications of Unixness.
6128 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
6130 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
6132 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
6134 * read.c (scm_lreadr): use scm_misc_error to improve one of the
6135 "unknown # object" error messages.
6137 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
6138 (scm_i_index) and declare it static. Add a 'direction' argument
6139 to indicate what way the search should go.
6140 (scm_i_index): throw out-of-range error instead of wrong-type-arg
6142 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
6143 strop.h: remove scm_i_index, scm_i_rindex prototypes.
6145 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
6147 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
6149 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
6150 to avoid clash with various scsh forks.
6152 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
6154 The following two changes (ramap.c, throw.c) are motivated by the
6155 apparent unportability of forward declarations of static arrays of
6156 the form `static foo bar[];'.
6158 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
6159 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
6161 * throw.c (scm_throw): Moved above scm_ithrow.
6163 * options.h: Removed the extern declarations of scm_yes_sym and
6164 scm_no_sym since these are static.
6166 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
6168 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
6170 * Makefile.am: remove AWK=@AWK@.
6171 Add a rule for generating errnos.list.
6172 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
6174 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
6175 don't extract errnos, just set a variable (avoids the
6176 need to recompile error.c just because configure is run.)
6178 * unif.h: update prototypes.
6179 * unif.c (scm_uniform_array_read,write): change the offset and
6180 length arguments to start and end, for consistency.
6182 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
6184 * ioext.h: update prototypes.
6185 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
6186 scm_read_line_x, it's a more general procedure using an
6187 interface from scsh. read-line and read-line! are now defined
6189 Note that the new read-line trims the terminator
6190 by default, previously it was appended to the returned string. An
6191 optional argument specifies how to process the terminator (scsh
6192 compatible). For the old behaviour: (read-line port 'concat).
6193 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
6194 returns a pair, but is converted to multiple values if the scsh
6197 socket.h: update prototypes.
6198 * socket.c (scm_recvfrom): for consistency with other procedures,
6199 take start and end as separate optional arguments.
6200 (scm_recv, scm_recvfrom): don't allow the second argument
6201 to be a size, only a buffer. Change the scheme names to
6202 recv! and recvfrom!. Don't return the buffer.
6204 * ioext.h, posix.h: move prototypes too.
6205 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
6206 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
6207 "read.h" and "unif.h".
6208 * ioext.c: include "chars.h"
6210 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
6212 * dynl.c: The dynamic linking and module registration functions
6213 are now defined even when dynamic linking is not available for the
6214 host system. Some of their functionality can be done without
6215 dynamic linking; when it's really needed, they throw errors.
6217 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
6219 * configure.in: Only define DYNAMIC_LINKING when one of the system
6220 dependent functions is detected.
6221 * dynl.c (scm_dynamic_func): New function to get the address of a
6222 function in a dynamic object.
6223 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
6224 produced by scm_dynamic_func as the thing to call.
6226 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
6228 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
6229 (scm_register_module_xxx, scm_registered_modules,
6230 scm_clear_registered_modules): New functions.
6232 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
6234 * symbols.c (scm_sysintern): Renamed to
6235 scm_sysintern_no_module_lookup.
6236 (scm_sysintern): New function to take the place of the old
6237 scm_sysintern. It uses the current toplevel lookup closure to give
6238 the symbol its value. This is a temporary hack to put packages
6239 like gtcltk into their own module.
6240 (scm_can_use_top_level_lookup_closure_var): New variable to tell
6241 us whether `scm_top_level_lookup_closure_var' has been initialized
6243 * eval.c (scm_init_eval): Set it.
6245 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6247 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6248 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6250 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6252 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6253 scm_sys_dup): deleted: FD capability will be added to other
6255 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6256 scm_fd_free, fd_smob, scm_intern_fd.
6257 (scm_open): renamed from scm_sys_open. Return a port instead of
6258 an FD object. Make the mode argument optional.
6259 (scm_sys_create): deleted, it's just a special case of open.
6260 (scm_init_filesys): move interning of constants O_CREAT etc.,
6261 here (were previously using SCM_CONST_LONG macro).
6262 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6264 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6265 include "fports.h" and <stdio.h>
6266 (scm_stat, scm_select): don't support FD objects.
6268 * error.h: adjust scm_syserror_msg prototype.
6269 * error.c (scm_syserror_msg): take an extra argument for errno.
6270 Using the global value didn't always work, since it could be
6271 reset by procedure calls in the message or args arguments.
6273 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6274 I don't understand why the check was there (and what about the
6277 * strop.c (scm_string_copy): allow shared substrings to be copied.
6279 * unif.h: corresponding change to prototypes.
6280 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6281 recognize two new optional arguments: offset and length. Allow
6282 the port argument to be an integer (file descriptor, for scsh).
6283 Include <unistd.h> for "read" prototype.
6285 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6287 * socket.c: don't include filesys.h.
6289 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6291 * Makefile.am: add AWK=@AWK@ (?)
6293 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6295 Add a rule to generate errnos.c from errnos.
6296 * error.c (scm_init_error): include errnos.c.
6297 * errnos_cnvt.awk: new file, converts the list of errno codes to
6299 * errnos_get.c: new file.
6300 * errnos.default: new file, contains errnos to try if they can't
6301 be extracted from errno.h.
6302 * configure.in: if using GCC, try and extract errno codes from
6306 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6308 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6309 * Makefile.am: Made libguile into a libtool library.
6310 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6311 Set libtool_libs to indicate that libguile is a libtool library.
6312 See guile/ChangeLog for details.
6313 * .cvsignore: ignore "*.lo", the libtool library objects.
6315 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6317 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6318 use htons in getservbyport argument.
6320 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6322 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6323 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6326 * objprop.c (scm_object_property): No need to take the CDR of the
6327 value returned by scm_object_properties, since Aug 20 change.
6329 * configure.in: When checking for struct linger, #include
6330 <sys/types.h> as well as <sys/socket.h>. I've never known
6331 <sys/types.h> to cause any portability problems, and Solaris's
6332 <sys/socket.h> needs it.
6333 * configure: Rebuilt.
6335 I think the Sun compiler has chosen a perverse way to interpret
6336 ANSI declarations combined with K&R definitions. We'll
6337 appease it a little bit. But when it invades France, we fight.
6338 * print.c (scm_iprlist): Change 'tlr' argument to an int.
6339 * print.h (scm_iprlist): Here too.
6340 * numbers.c (scm_divbigdig): Change definition to match
6341 declaration in numbers.h.
6342 * unif.c (scm_makflo): Change definition to match declaration in
6345 * init.c (scm_boot_guile): Don't return the value of
6346 scm_boot_guile_1. This function doesn't return a value;
6347 scm_boot_guile_1 doesn't return a value (or return at all).
6349 * eval.c (unmemocopy): Add a semicolon to appease the Sun
6352 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
6353 compile. I have a feeling this function is a bad idea anyway ---
6354 one should always test for features, not systems.
6356 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
6357 semicolons. Only pure luck kept this from being noticed earlier.
6359 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
6361 * socket.c (scm_recvfrom): Added missing semicolon.
6363 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6365 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
6366 the buffer and start and end positions for scsh networking
6369 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
6371 * configure.in: Revert previous change to this file; the problem
6372 is due to transient automake weirdness.
6373 * configure: Rebuilt.
6375 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
6376 PLUGIN/guile.libs. configure generates the latter from the former.
6377 * Makefile.in: Rebuilt.
6379 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
6380 need this if we install scripts, like guile-snarf.
6381 * configure: Rebuilt.
6383 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6385 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
6387 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
6389 * socket.c (scm_addr_vector): fix faulty scm_listify.
6391 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
6393 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
6394 style block comment is no longer considered an error.
6396 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
6398 * PLUGIN/guile.libs.in: New file.
6399 * PLUGIN/guile.libs: Removed from repository.
6400 * configure.in: Create PLUGIN/guile.libs from
6401 PLUGIN/guile.libs.in. This is for including additonal libraries
6402 needed for dynamic linking.
6403 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
6404 instead of PLUGIN/guile.libs.
6406 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
6408 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
6410 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
6411 occurrences of the given element from the list, not just the
6412 first. This is how the Emacs Lisp functions behave, how the
6413 analogous Common Lisp functions behave, and (I believe) how the
6414 older Maclisp functions worked. I realize that this change may
6415 break code, but it seemed better to break it before the Guile
6418 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
6419 Their prototypes were already present in gc.h, but they weren't
6421 (scm_init_storage): Initialize scm_protects.
6422 * root.c (scm_protects): New element of scm_sys_protects.
6424 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
6426 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6428 * libguile.h: Added #include "libguile/net_db.h".
6430 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
6431 30 change. That file is only meant for communication between the
6432 configuration process and load.c. If code linked against libguile
6433 wants to get at the paths mentioned in libpath.h, it can call
6434 functions declared in load.h.
6436 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6438 * libguile.h: Removed #include "libguile/fdsocket.h"
6440 * net_db.c: Added #include <sys/socket.h>.
6442 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
6444 * filesys.c (scm_input_waiting_p): use select in preference to
6445 FIONREAD, since the latter doesn't detect EOF.
6446 Throw error if neither select nor FIONREAD available.
6448 * socket.c (scm_connect): take a port, not a fd object.
6449 (scm_fill_sockaddr): throw an error if fam is not recognised.
6450 (scm_bind): use scm_fill_sockaddr.
6451 (scm_listen): take a port, not a fd object.
6452 (scm_accept): take and return a port. return #f in the car if
6453 address can't be got
6454 (scm_sock_fd_to_port): new procedure.
6455 (scm_socket): use scm_sock_fd_to_port.
6456 (scm_addr_vector): throw error if unrecognised address type.
6457 take an extra argument with the calling procedure name.
6458 (scm_getsockname): take a port. return #f if address can't be got.
6459 (scm_getpeername): take a port. return #f if address can't be got.
6460 (scm_recvfrom): take a port. return #f for address component if can't
6462 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6463 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6465 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6467 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6468 use separate data pointers, to allow them to be designed
6469 independently and reused.
6470 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6471 Renamed from catch_body, catch_handler, and uncaught_throw; made
6473 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6475 (scm_catch): Use the above.
6476 (scm_throw): Don't bother printing a message for an uncaught
6477 throw; we establish a default handler in init.
6478 * throw.h (scm_internal_catch): Prototype updated.
6479 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6481 (struct scm_body_thunk_data): New structure, used as data
6482 argument to scm_body_thunk.
6483 * init.c (struct main_func_closure): New structure, packaging up
6484 the data to pass to the user's main function.
6485 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6486 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6487 scm_internal_catch to establish a catch-all handler, using
6488 scm_handle_by_message. This replaces the special-case code in
6490 (invoke_main_func): Body function for scm_internal_catch; invoke
6491 the user's main function, using the main_func_closure pointer to
6492 decide what to pass it.
6493 * root.c (struct cwdr_body_data): Remove handler_proc member.
6494 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6495 (cwdr_handler): Removed.
6497 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6499 * socket.h (SCM_P): update bind prototype.
6500 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6501 include "feature.h".
6502 (scm_socket): return a port, not a file descriptor object.
6503 include "fports.h" and <unistd.h>
6504 (scm_bind): take a port, not a file descriptor object.
6505 take an extra argument for address args.
6507 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6508 INADDR_NONE, INADDR_LOOPBACK.
6510 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6512 * init.c: include net_db.h and not fdsocket.h.
6513 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6515 * Makefile.am: corresponding changes.
6516 * socket.h: renamed from fdsocket.h, fix names.
6517 * net_db.h: renamed from socket.h, fix names.
6518 * socket.c: renamed from fdsocket.c.
6519 remove _sys from procedure names.
6520 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6521 add "socket" to features list.
6522 * net_db.c: renamed from socket.c.
6523 remove _sys from procedure names.
6524 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6525 add "net-db" to features list.
6526 include "net_db.h". don't include <sys/socket.h> or
6529 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6531 * tags.h (scm_tags): Removed comma at end of last enumerator.
6533 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6535 Don't use GCC extensions to allocate space for debugging frames.
6536 (Here he goes again! Why do we put up with this?!)
6537 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6538 an scm_debug_info structure, not an in-line array of them. Add
6539 'info' member, to say how many vect elements we've used, for eval
6541 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6542 a new variable debug_info_end to mark the end of vect, instead of
6543 the address of the 'info' pointer itself.
6544 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6545 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6546 (SCM_APPLY): Explicitly allocate space for debug.vect.
6547 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6548 * stacks.c: Adjusted for new debug frame structure.
6549 (RELOC_INFO, RELOC_FRAME): New macros.
6550 (stack_depth, read_frames): Use them, and new scm_debug_frame
6551 element 'info', instead of magically knowing that eval frames have
6552 an info pointer sitting after vect.
6553 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6555 (scm_init_stacks): Formatting tweaks.
6557 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6559 Give GCC more control flow information, so it can be sure that
6560 variables aren't used uninitialized.
6561 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6562 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6563 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6564 scm_misc_error): Tell GCC that these functions never return.
6565 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6566 out the field type, call abort if SCM_ASSERT returns, to placate
6568 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6569 scm_wta ever returns. We can't handle this case anyway, and this
6570 gives the optimizer more information.
6571 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6572 scm_wta ever returns.
6574 In some cases, the code is fine, but GCC isn't smart enough to
6575 figure that out; this usually happens when one variable is only
6576 initialized and used when a particular condition holds true, and
6577 we know that condition will never change within a given invocation
6578 of the function. In this case, we simply initialize the variables
6579 to placate the compiler, hopefully to a value which will cause a
6580 crash if it is ever actually used.
6581 * print.c (scm_iprin1): Initialize mw_pos.
6582 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6583 * throw.c (scm_ithrow): Initialize dynpair.
6584 * unif.c (scm_uniform_vector_ref): Initialize cra.
6585 * struct.c (init_struct): Initialize prot.
6586 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6588 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6589 if EXPR contains no expressions.
6591 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6593 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6594 cause an infinite loop (???). So much for the algebraic
6595 equivalency of variable-sized arrays and alloca...
6597 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6599 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6600 a SCM boolean, not a C boolean.
6602 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6604 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6605 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6606 rules for raising scm_mtrigger. Previously, unfortunate but not
6607 unlikely circumstances could result in almost constant invokation
6608 of the gc. Now, this situations should be less likely, but they
6609 are not prevented completely.
6611 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6613 * numbers.c (scm_fuck): Procedure removed; looks like old test
6615 * numbers.h: Prototype removed.
6617 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6619 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6620 array to a pointer, to match my Nov 21 change in eval.c.
6622 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6624 * libguile.h: Added #include "libguile/backtrace.h", #include
6625 "libguile/stacks.h".
6627 * strings.c (scm_string scm_make_string scm_string_ref
6628 scm_string_set_x scm_string_equal_p scm_string_append):
6629 Bugfix according to scm patch from Aubrey Jaffer:
6630 Corrected long-standing
6631 (not (eqv? (integer->char 128)
6632 (string-ref (make-string 1 (integer->char 128)) 0)))
6633 bug found by John Kozak <jk@noontide.demon.co.uk>.
6635 * strports.c, strports.h: Make scm_eval_0str return the value of
6636 the last expression evaluated (previously, it returned void).
6638 * strports.c, strports.h: New function: scm_read_0str. Does what
6641 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6643 * simpos.c (scm_getenv): return #f if string can't be found in the
6644 environment instead of throwing an exception, for compatibility
6645 with numerous other systems.
6647 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6649 * Makefile.am (.c.x): Use guile-snarf.
6650 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6652 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6654 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6656 * backtrace.c (scm_display_error_message): Made non-static, and
6657 renamed from display_error_message.
6658 * backtrace.h (scm_display_error_message): Added extern decl.
6659 * throw.c (uncaught_throw): Use it to display the error message.
6661 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6663 * inet_aton.c: Use #if 0, not #ifdef 0.
6665 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6667 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6668 to convert the returned value.
6669 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6670 the offset argument.
6672 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6674 Add new interface to catch/throw, usable from C as well as
6676 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6677 (scm_internal_catch): New function, replaces...
6678 (scm_catch_apply): Deleted.
6679 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6680 mechanism which is a bit more code, but can be used nicely from C
6681 and implement the Scheme semantics as well.
6682 (scm_internal_catch): This is the replacement; it's named after
6683 the analogous function in Emacs.
6684 (scm_catch): Reimplemented in terms of the above.
6685 (struct catch_body_data, catch_body, catch_handler): New
6686 functions, used by scm_catch.
6687 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6688 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6689 support for new cwdr.
6691 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6694 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6696 * acconfig.h: Added DYNAMIC_LINKING symbol.
6697 * configure.in: Add option and checks for dynamic linking.
6698 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6699 dynl.h: New files for dynamic linking support.
6700 * Makefile.am (libguile_a_SOURCES):
6702 (modinclude_HEADERS): Added "dynl.h".
6703 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6705 * init.c (scm_boot_guile_1): Call
6706 scm_init_dynamic_linking to initialize dynamic linking support.
6708 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6710 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6711 (as we Schemers say). It needs to be global, so that I can tweak
6712 it for the proper operation of unexec.
6713 (scm_boot_guile_1_live): New variable, see above.
6715 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6717 * guile-snarf.sh: Removed.
6718 * PLUGIN/guile.libs: Added dependency for -lm.
6719 * acinclude.m4: Renamed from aclocal.m4.
6720 * PLUGIN/greet: Removed.
6721 * Makefile.am, aclocal.m4: New files.
6722 * configure.in: Updated for Automake.
6724 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6726 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6727 and not top_level_lookup_thunk_var.
6729 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6731 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6733 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6735 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6736 Scheme function, instead of syntax. Single argument is now a
6739 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6741 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6742 scm_ra_divide): Properly terminate statements passed as arguments
6743 to IVDEP macros. (Thanks to Bernard Urban.)
6745 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6746 with non-constant sizes. (Thanks to Bernard Urban.)
6748 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6750 It's an "eval closure", not an "eval thunk." A thunk is a
6751 function of no arguments.
6752 * root.h (struct scm_root_state): Renamed
6753 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6754 (scm_top_level_lookup_closure_var): Renamed from
6755 scm_top_level_lookup_thunk_var.
6756 * root.c (mark_root): Uses changed.
6757 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6758 * init.c (scm_start_stack): Uses changed.
6759 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6760 Change scheme-visible name to *top-level-lookup-closure* from
6761 *top-level-lookup-thunk*.
6763 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6765 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6766 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6768 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6770 * gc.c (struct scm_heap_seg_data): Doc fixes.
6772 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6773 sweeping. Then, prepend each segment's free cells to its
6774 freelist, rather than wiping out the old value. (Thanks to Marius
6777 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6778 scm_check_freelist, scm_debug_newcell): New functions and
6779 variables, for debugging freelist problems.
6780 * pairs.h (SCM_NEWCELL): New debugging version added.
6781 * gc.h (scm_debug_newcell): Added extern declaration, used by
6782 debugging version of SCM_NEWCELL.
6784 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6786 On some systems <libc.h> conflicts with <unistd.h>, and should not
6787 be #included at all.
6788 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6789 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6790 * configure.in: Call it.
6791 * posix.c, filesys.c: Use its results to decide whether or not to
6793 * configure, scmconfig.h.in: Rebuilt with autoconf and
6796 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6798 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6799 pointer to the stdio stream before calling scm_setbuf0, so the
6800 latter will be able to retrieve it. I'm surprised this didn't
6801 segfault earlier. (Thanks to Christopher Lee.)
6803 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6805 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6808 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6810 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6811 number of stack narrowing specifier pairs. The first specifier in
6812 a pair controls inner border, the second the outer border. A
6813 number means cut that number of frames, a procedure object means
6814 cut until that object is found in operator position in a frame.
6816 * root.c (cwdr): Bugfix.
6818 * read.c: Recording of positions disabled by default.
6820 * procs.c (scm_closure_p): New function.
6822 * posix.c (scm_tmpnam): New function.
6824 * load.c: Added #include "throw.h".
6825 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6828 * load.c, load.h (scm_read_and_eval_x): New function.
6830 * eval.c: Renamed debug option "deval" to "debug".
6832 (scm_eval_x): `eval!' is no longer accessible from the scheme
6833 level. Motivation: We can't allow operations which introduce
6834 glocs into the scheme level. Guile's type system can't handle
6835 these as data. Use `eval' or `read-and-eval!' as replacement.
6837 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6838 SCM_CONSP since this is a macro!; Set vframe.prev to
6839 scm_last_debug_frame instead of 0. In this way we can look
6840 "above" the virtual start stack frame if we wish.
6841 (scm_debug_hang): New function: Useful for debugging Guile in
6842 certain tricky situations. Will probably be removed later...
6844 * debug.h: Changed semantics of debug option "backtrace". This
6845 option now only indicates whether we want automatic backtrace at
6848 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6850 * ports.c: #include "filesys.h"
6851 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6853 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6854 Motivation: This is system specific code which is related to file
6855 I/O. It also may use select. Added code by Gary Houston to
6856 detect presence of character in stdio buffers.
6858 * libguile.h: #include "libguile/libpath.h"
6860 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6861 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6862 SCM_SITE_DIR; Install libpath.h among the other include files.
6864 * load.c, load.h (scm_sys_package_data_dir): New function.
6866 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6868 * stacks.h: Bugfix: Don't use tail-array length field as stack
6869 length field! This screwed GC.
6871 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6873 * _scm.h: Added #ifndef around definition of macros min and max.
6875 * __scm.h: Added hooks for threads to plugin to in ints protection
6876 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6877 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6878 the main code in these macros duplicated and spread over multiple
6879 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6880 SCM_THREAD_SWITCHING_CODE.
6882 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6884 * snarf.h: New file.
6885 * guile-snarf.sh: New file.
6886 * Makefile.in (inner_h_files): Added snarf.h
6887 (ancillary, install, uninstall, distclean): Added actions for
6889 (.c.x): Use guile-snarf.
6890 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6891 (gen_c_files): Note that these depend on guile-snarf.
6892 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6893 now in "snarf.h". Added #include "snarf.h" to get them.
6894 * libguile.h: Added #include "snarf.h".
6895 (Patches applied and tweaked by Jim Blandy.)
6897 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6899 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6900 standards suggest against providing prototypes for system
6901 functions. Thanks to Greg Troxel.
6903 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6905 * strports.c (scm_eval_0str): New function.
6906 #include "read.h", to get prototype for scm_read.
6907 * Makefile.in (strports.o): Update dependencies.
6908 * strports.h: New prototype.
6910 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6911 scheme name from "int?" to "integer?". It seems to do the job.
6912 * numbers.h: Rename prototype too.
6913 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6916 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6917 scm_num_eq_p): Rename these according to R4RS conventions: call
6918 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6919 to making libguile R4RS compliant without ice-9...
6921 * load.c (scm_sys_search_load_path): Search for files under all
6922 extensions listed in the %load-extensions variable. If FILENAME
6923 is absolute, return it unchanged, without searching the load path.
6924 (scm_loc_load_extensions): New variable, pointing to
6925 %load-extensions' value cell.
6926 (scm_init_load): Initialize it, and the value it points to.
6927 (scm_primitive_load_path): Improve error reporting.
6929 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6930 of new Scheme variable %load-hook.
6931 (scm_primitive_load): Apply %load-hook to filename.
6933 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6935 * configure.in: add tests for figuring out whether buffered data
6936 is available in a FILE structure, which is needed by char-ready.
6938 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6941 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6942 exceptions using misc_error instead of syserror. It seems a bit
6943 odd to throw an exception if a string can't be found in the
6944 environment, but it's consistent with open-file, stat etc.
6945 (simpos.h): remove sys_ from getenv.
6947 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6948 occurs, throw an error instead of returning errno. Return value
6950 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6952 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6954 * filesys.c (scm_stat2scm): derive file type and permissions from
6955 the stat mode and append them to the returned vector.
6956 There isn't much overhead in doing this and it avoids the need to
6957 work with S_IRUSR et al. in Scheme.
6958 Define symbols scm_sym_regular etc.
6959 (scm_init_filesys): don't intern S_IRUSR etc.
6961 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6962 and s_primitive_load_path.
6964 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6966 * error.h: don't declare error symbols. prototype for scm_misc_error.
6968 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6971 * error.c: use SCM_SYMBOL to set up error keys.
6972 scm_misc_error: new procedure.
6974 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6976 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6977 between `#!' and `!#' is ignored.
6978 (skip_scsh_block_comment): New function.
6980 * feature.c (scm_set_program_arguments): New argument, FIRST.
6981 * feature.h: Update prototype.
6982 * init.c (scm_boot_guile_1): Pass new argument to
6983 scm_set_program_arguments.
6985 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6987 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6988 (scm_boot_guile): Call scm_set_program_arguments here, later than
6989 the old initialization.
6991 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6992 initialization procedure.
6993 - Delete in, out, err arguments; there are other perfectly good
6994 ways to override these when desired.
6995 - Delete result argument; this function shouldn't ever return.
6996 - Rename init_func argument to main_func, for less confusion.
6997 - Delete boot_cmd argument; main_func is more general.
6998 -Add 'closure' argument, to help people pass data to main_func
6999 without resorting to global variables.
7000 - Abort if reentered; don't bother returning an error code.
7001 - Call scm_init_standard_ports to set up the default/current
7002 standard ports; no need to pass them to scm_start_stack.
7003 - Remove code to evaluate the boot_cmd, and start the repl; let
7004 the user do something like that in main_func if they want.
7005 - Remove code to package up a return value; main_func can do any
7007 - Call exit (0), instead of returning.
7008 (scm_start_stack): Don't initialize the I/O ports here; that's
7009 weird. Delete in, out, err arguments. Move guts to
7010 scm_init_standard_ports, scm_stdio_to_port.
7011 (scm_init_standard_ports): New function, to set up current and
7012 default standard ports.
7013 (scm_start_stack, scm_restart_stack): Make these static.
7014 * init.h (scm_boot_guile): Adjust declaration.
7015 (scm_start_stack, scm_restart_stack): Remove externally
7016 visible declarations for these.
7017 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
7019 * fports.c (scm_stdio_to_port): New function. Its guts used to be
7020 written out several times in scm_start_stack.
7021 * fports.h: New declaration for the above.
7023 * feature.c (scm_set_program_arguments): New function.
7024 * feature.h: New declaration for the above.
7026 * ports.c: Formatting tweak.
7028 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
7030 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
7031 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
7032 for obtaining the address of a car or cdr field. Motivation:
7033 &SCM_CXR make assumptions about the internal structure of the
7036 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
7037 Motivation: see SCM_CXRLOC.
7039 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
7040 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
7041 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
7042 Motivation: Safer use. Some other macros are defined in terms of
7043 these operations. If these are defined using the SCM_SETCXR
7044 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
7045 to inefficiency and an <e1> with side-effects could potentially
7046 break. Also, these particular operations are heavily utilized in
7047 the garbage collector. In unoptimized code there will be a
7050 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
7051 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
7052 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
7053 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
7054 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
7055 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
7056 vports.c: Cleaned up use of pairs: Don't make any special
7057 assumptions about the internal structure of selectors and
7058 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
7059 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
7060 (Among other things, this change makes it easier to build Guile
7061 with certain compilers which have problems with casted lvalues.)
7063 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
7065 * stacks.c: Improve selection of relevant stack frames when making
7066 a stack object. Introduce one level of indirection in the stack
7067 object to make it possible to "narrow" to a certain region of the
7068 stack. This facilitates making use of more clever algorithms (not
7069 implemented) for selecting relevant frames and gives a cleaner
7070 design since selection of frames can be done independently of
7071 extraction of frames from the real stack.
7072 (scm_stack_id): Also take #t as argument which means look at
7075 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
7076 Turn n_tail into an integer directly representing current number
7077 of frames in stack. Add field tail.
7079 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
7081 * debug.c (scm_make_memoized): Made it available at scheme level.
7082 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
7083 SCM_NIMP before applying heavier predicates in argument checking.
7084 (scm_local_eval): Also take memoized object as argument.
7086 * backtrace.c (scm_display_error): Just a safety measure: Stacks
7087 aren't created with zero length, but should such a strange
7088 creature suddenly turn up...
7090 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
7092 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
7093 `del', for the sake of C++ compilers. (Patch applied by JimB.)
7095 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
7097 * variable.c (scm_make_variable): Make the name hint optional, as
7099 (anonymous_variable_sym): Renamed from variable_sym. All uses
7102 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
7103 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
7104 of scm_primitive_load_path was also changed to
7105 "primitive-load-path", from "%try-load-path". Callers changed.
7106 We'd like to respect the convention that a function named
7107 "try-mumble" should behave just like the function called "mumble",
7108 but return #f instead of signalling some error.
7109 * load.h: Rename prototypes.
7111 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7113 * print.c (make_print_state, grow_print_state), print.h: Modified
7114 the print state representation: Don't use a tail array for
7115 recording of circular references. Resizing of the print state
7116 structure invalidates the print state pointer. To avoid passing
7117 around an indirect print state reference to all printing
7118 functions, we instead let the print state reference a resizable
7121 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7123 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
7124 Don't crash when passed an improper list terminated by a
7125 non-immediate value.
7127 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
7129 Allocate data for structures on an eight-byte boundary, as
7130 required by the tagging system.
7131 * struct.c (alloc_struct): New function.
7132 (scm_make_struct, scm_make_vtable_vtable): Call it.
7133 * struct.h (scm_struct_n_extra_words): Bump to 3.
7134 (scm_struct_i_ptr): New "field".
7135 * gc.c (scm_gc_sweep): When we need to free the data, use the
7136 information stored by alloc_struct to find the beginning of the
7137 block allocated to the structure, so we can free it.
7139 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7141 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
7144 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
7145 (scm_debug_info): New member: id.
7147 * stacks.c: Stacks are now represented as structs; Stacks have an
7148 id given to them by `start-stack'.
7149 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
7151 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
7152 Changed stack representation.
7154 * debug.c (scm_procedure_name): Try procedure property `name' for
7155 compiled closures aswell.
7157 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
7159 * eval.c: scm_i_name moved to gsubr.c
7160 (scm_m_define): Record names of all kinds of procedure
7161 objects. (Earlier, only closures were recorded.)
7163 * procprop.h: Added declaration of scm_i_name.
7165 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
7166 (scm_make_gsubr): Record names of compiled closures.
7168 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7170 * debug.c, debug.h: Removed obsolete code.
7172 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
7173 stacks.c: Renamed regs --> scm_contregs.
7175 * print.c (scm_free_print_state): Cleanup print state before
7176 returning it to pool. It is better to do it here than in
7177 scm_prin1 since scm_prin1 is called often.
7179 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
7180 s_set_source_property_x): Check that first argument is a pair or a
7183 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
7184 scm_i_line, scm_i_column and scm_i_breakpoint global.
7186 * init.c: Added #include "backtrace.h" and #include "stacks.h".
7187 (scm_boot_guile_1): Added calls to scm_init_backtrace and
7190 * debug.h: Added debug object smob declaration and macro
7193 * configure.in: Build with backtrace.o and stacks.o if debug
7196 * Makefile.in: Added entries for new files: backtrace.c,
7197 backtrace.h, stacks.c and stacks.h.
7199 * symbols.c (scm_sym2ovcell): Fixed documentation.
7201 * _scm.h (min, max): Added.
7203 * async.c: Moved `min' macro to _scm.h.
7205 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
7206 SCM_BACKTRACE_INDENT.
7208 * eval.c: Added new debug options `maxdepth' and `indent'.
7210 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
7212 * print.h: Added selector SCM_PRINT_STATE.
7214 * print.c: New functions: scm_make_print_state,
7215 scm_free_print_state.
7217 * print.h: Added declarations for scm_make_print_state,
7218 scm_free_print_state.
7220 * debug.c (scm_m_start_stack): New acro.
7222 * debug.h: Small cleanup.
7224 * init.c (scm_boot_guile_1): Moved scm_init_debug below
7227 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

7252 More prototype-related changes from Marius Vollmer:
7253 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7254 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7255 * ports.h (ptobfuns): Added prototypes. This means some casting in
7257 * fports.c: Added casts for initializations, since the functions
7258 are defined to take FILE * as their stream argument, not SCM.
7259 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7260 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7261 to `char *str_data' to conform to prototype.
7263 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7265 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7267 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7269 * stime.c, stime.h: use SCM_P method.
7271 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7273 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7274 be given at least two arguments. Insist that lst's last element
7275 be a list, but don't make any requirements of its predecessors.
7277 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7279 * eval.c (scm_nconc2last): Revert last change; there seems to be
7280 other stuff going on here.
7282 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7284 * eval.c (scm_nconc2last): Make sure that each element of lst
7285 (which is a list of argument lists, except for the tail) is a
7286 proper list, i.e., finite and terminated by '().
7288 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7290 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7293 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7294 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7297 * vectors.c (scm_make_vector): Fill vectors with the undefined
7298 value, to help make Guile Scheme code more portable to other
7301 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7302 * symbols.h, tags.h: Doc fixes.
7304 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7306 * async.c (scm_take_signal): Doc fixes.
7308 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7310 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7311 want to subtract it from the modulus; we just want to leave it
7314 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7316 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7319 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7321 * throw.c (scm_catch_apply): Finished implementation of
7324 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7326 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7328 (scm_init_filesys): set "i/o-extensions" feature.
7331 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7333 * Makefile.in (root.o): Correct dependencies.
7335 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7337 * Makefile.in: Added dependency entry for root.o.
7339 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
7340 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
7342 * init.c (scm_start_stack): Set initial root continuation number
7345 * procs.c: New function: scm_thunk_p.
7347 * procs.h: Added declarations of scm_thunk_p.
7349 * root.c: Renamed `call-with-new-root' -->
7350 `call-with-dynamic-root'.
7351 (cwdr): Removed allocation of new root state. This should be done
7352 separately by use of scm_make_root.
7353 (scm_apply_with_dynamic_root): New function: Does what it
7354 sounds like. Needed when spawning threads.
7356 * root.h: Added member last_debug_frame to root state.
7357 Added #include "libguile/debug.h"
7359 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
7360 arguments. The motivation is that code in root.c needs catch
7361 functionality, and we want to avoid code duplication.
7362 New functions: scm_catch, scm_lazy_catch. These are wrappers for
7363 scm_catch_apply. scm_lazy_catch is intended to introduce catch
7364 handlers that run without popping the stack into the dynwind
7367 * throw.h: Added prototypes for scm_catch_apply and
7370 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7372 * root.h (scm_root, scm_set_root): Decouple thread support details
7373 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
7374 SCM_SET_THREAD_LOCAL_DATA.
7376 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
7377 and tortoise scanning loop.
7379 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
7381 * Makefile.in: Rebuild dependencies.
7383 * libguile.h: #include "libguile/print.h" before "smob.h", since
7384 the latter uses the print_state structure.
7386 * throw.c (scm_ithrow): Use the correct variable when checking to
7387 see if a given element of scm_dynwinds is a valid catch.
7389 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
7390 structure, abort; don't just silently ignore the garbage.
7392 * _scm.h: #include "print.h" here, since it seems to be used just
7394 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
7395 strports.c, unif.h: Don't #include "print.h".
7397 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7399 * feature.h (scm_loc_features): Removed external declaration.
7400 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
7402 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7404 * feature.c (scm_init_feature): Added threads feature (needs to be
7405 initialized here, since features doesn't exist when
7406 scm_init_threads is called).
7408 * libguile.h: Added #include "libguile/../threads/threads.h".
7409 (This is a kludge to get thread support working. This should be
7412 * configure.in, acconfig.h: Added flags for thread support.
7414 * scmsigs.c: Define `signal' to be `pthread_signal' if using
7417 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
7418 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
7421 * _scm.h: Added conditional #include "threads.h"
7423 * __scm.h (SCM_ASYNC_TICK): Added call to macro
7424 SCM_THREADS_SWITCHING_CODE.
7426 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
7427 allocate the basic dynamic root object.
7428 (scm_boot_guile): Added call to scm_init_root.
7430 * root.c, root.h: Added root smob.
7431 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
7432 functions: Implements dynamic roots mostly according to spec in
7433 SCM manual. Main difference is that the second argument is a
7434 throw handler rather than an error "thunk".
7436 * root.h: Added declaration of scm_init_root.
7438 * root.c: Added #include "genio.h", #include "smob.h", #include
7439 "pairs.h", #include "throw.h", #include "dynwind.h", #include
7441 (scm_init_root): Added #include "root.x".
7443 * throw.c: Added #include "stackchk.h"
7444 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
7445 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
7446 can be used in scm_call_with_new_root; Added reenabling of stack
7447 checking when catching a throw.
7449 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
7451 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
7453 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
7454 element is not found, as per R4RS.
7456 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7458 * list.c: Doc fixes throughout.
7460 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7462 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7463 declare the char * to be const. Avoids a warning in rgx.c.
7465 * ports.h: spelling fix.
7467 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7470 * load.c (scm_sys_try_load_path): throw an error if file not found
7471 (like it says it in NEWS).
7473 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7475 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7476 PROPS slot to '(), not #f; it's an empty alist.
7478 * throw.h, throw.c: Use SCM_P instead of #if hair.
7480 Remove special support for uncaught throws; see throw.c for
7482 * throw.c (uncaught_throw): New function.
7483 (scm_ithrow): Call uncaught_throw if we don't find a throw
7484 target; don't mess with scm_bad_throw_vcell.
7485 (scm_bad_throw_vcell): Variable deleted.
7486 (scm_init_throw): Don't initialize it.
7488 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7491 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7493 * numbers.c (scm_istr2int): If the number is short (as most
7494 numbers are), just call scm_small_istr2int to deal with it.
7495 (scm_small_istr2int): New function, created by un-#ifdefing the
7496 non-bignum version of scm_istr2int and renaming it.
7498 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7500 * load.c (scm_sys_try_load): don't check whether value returned
7501 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7502 Change the Scheme name from %try-load to primitive-load.
7504 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7505 Can avoid passing a message, allowing it to be derived in the
7506 error handler (e.g., if we want to throw to the key both from
7509 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7511 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7512 references now have a new appearance which is more compact and
7513 also gives a clue about what the target of the reference is.
7514 By setting parameters in the print state, more fancy printing can
7515 be achieved. This is used by the (not yet commited) backtrace
7518 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7520 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7523 * print.c: Added #include "struct.h". Removed function
7526 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7527 scm_iprin1. Removed prototype for scm_prlist.
7529 * arbiters.c (prinarb),
7530 async.c (print_async),
7531 debug.c (prindebugobj, prinmemoized),
7532 eval.c (prinprom, prinmacro),
7533 filesys.c (scm_fd_print, scm_dir_print),
7535 mallocs.c (prinmalloc),
7536 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7537 smob.h (scm_smobfuns),
7538 srcprop.c (prinsrcprops),
7540 unif.c, unif.h (scm_raprin1, rapr1),
7541 variable.c (prin_var): Changed argument `int writing' to
7542 `scm_print_state *pstate'.
7544 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7545 that it will be called before scm_init_print.
7547 * print.c (scm_prin1): Print states are now allocated when calling
7548 scm_prin1 and then passed around to all printing functions as an
7549 argument. A cache `print_state_pool' enables reuse of print
7551 (scm_make_print_state): New function.
7552 (scm_iprin1): Adaption to print states.
7553 (scm_iprlist): An initial "hare and tortoise" scan brings down
7554 time complexity to O (depth * N). (Better time complexity will be
7555 achieved when the printing code is completely rewritten.)
7557 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7559 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7560 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7561 it gets done whether or not the cache variable has a value.
7563 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7565 Distinguish #f and ().
7566 * __scm.h: #undef SICP.
7567 * pairs.h (SCM_EOL): Delete this definition, equating it with
7569 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7570 the value it used to have. Doc fixes, too.
7572 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7574 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7575 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7576 Lord's implementation of structs, allowing for tail arrays as
7577 described in the manual. Also fixed some bugs. (Both the interface
7578 and the implementation should be improved.)
7580 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7582 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7583 People who whish to see the source can do `(print-enable 'source)'.
7584 Removed #ifdef DEBUG_EXTENSIONS.
7586 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7588 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7589 integer (assuming for now accepting an integer is a good thing).
7591 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7592 %S will be used instead for write'ing arguments.
7594 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7595 asserts. fix a few other asserts.
7596 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7597 scm_uniform_vector_ref, scm_array_set_x,
7598 scm_dimensions_to_unform_array): change args in
7599 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7600 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7601 scm_substring_fill_x): likewise.
7602 gsubr.c (scm_gsubr_apply): likewise.
7603 eval.c (SCM_APPLY): likewise.
7605 * eval.c (4 places): replace scm_everr with lgh_error or
7608 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7609 scm_memory_error): new procedures.
7610 scm_everr: deleted. can use scm_wta, dropping first two args.
7611 scm_error: convert NULL subr to SCM_BOOL_F.
7613 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7616 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7619 * error.c, error.h: new error keys: scm_arg_type_key,
7620 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7622 scm_wta: reimplement using lgh_error instead of scm_everr.
7624 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7626 * gdbint.c: scm_lread now has one more argument.
7628 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7629 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7630 loading source from non-file ports, which, e. g., happens when
7631 using the Emacs interface).
7633 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7636 * read.c: Added code for recording of positions of source code
7637 expressions; New functions: recsexpr, scm_lreadrecparen;
7638 _scm_make_srcprops --> scm_make_srcprops
7639 (scm_flush_ws): Removed updating of positions counters. This work
7640 is already done by scm_gen_getc
7642 * read.h: Added prototype for scm_lreadrecparen
7644 * print.c: Added #include "alist.h"
7646 * eval.c: Added #include "hash.h"
7648 * eq.c: Added #include "ramap.h"
7650 * options.c: Documentation fixes.
7652 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.

7654 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7655 --> scm_make_srcprops
7657 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7658 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7659 function calls in the definition of the whash access macros.
7661 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7663 * init.c (scm_boot_guile): Add level of indirection to
7664 scm_boot_guile_1() to ensure that stack base pointer is properly
7665 initialized. There was no guarantee that variable i was the
7666 highest/lowest variable on stack (i.e. the call frame of
7667 scm_boot_guile was not completely protected from gc).
7669 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7671 * ports.h (scm_port_table): put back file_name, it will be used to
7672 support debugging. Undo related changes in fports.c, ioext.c,
7675 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7677 * ports.h (scm_port_table): remove file_name member for now, it seems
7679 * fports.c (scm_open_file): don't set file_name in PTAB.
7680 (prinfport): don't use file_name in PTAB.
7681 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7682 * ports.c (scm_add_to_port_table): don't intialize file_name.
7683 (scm_port_file_name): remove for now.
7684 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7686 * fports.h (scm_mkfile): prototype deleted.
7687 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7689 * debug.c, unif.c: use scm_out_of_range instead of
7690 wta for range errors (ASSERT still needs work).
7692 * error.c, error.h (scm_out_of_range): new procedure.
7694 * error.c, error.h (scm_out_of_range_key): new key.
7696 * posix.c (scm_sync): #else was missing.
7698 * error.c, error.h: append _key to names scm_num_overflow and
7701 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7702 of consing an empty list.
7703 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7704 of macros, saves code and string space.
7705 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7706 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7707 lower case. Rename scm_syserror_m to scm_syserror_msg.
7708 error.h: prototypes for new procedures.
7710 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7712 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7714 * error.c, error.h: setup scm_num_overflow key.
7716 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7717 Remove definition of SCM_OVSCM_FLOW.
7719 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7721 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7722 explicit message and args.
7724 * error.c, error.h, __scm.h: change system_error_sym to
7727 * error.c (system_error_sym): remove leading %% from the Scheme name
7730 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7732 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7734 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7735 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7736 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7737 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7738 renamed. (These were introduced by unsupervised name
7741 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7743 * print.c: Added code for detection of circular references during
7744 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7745 a hook for printing of closures (accessible via print options).
7746 This leads to a split of calls to scm_iprin1 into two classes:
7747 elementary print operations (e. g. the code which prints a smob)
7748 still use scm_iprin1 while top level calls (like scm_display) use
7749 scm_prin1. scm_prin1 begins by clearing the data structure used
7750 to record reference information.
7752 * print.h: Added declarations of scm_prin1 and scm_prlist.
7754 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7756 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7758 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7760 * error.c (err_head): scm_iprin1 --> scm_prin1
7762 * debug.c: Adjusted header comment.
7766 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7768 * strerror.c: Doc fix.
7770 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7772 * gdbint.c (gdb_read): Now possible to run during GC.
7773 (unmark_port, remark_port): New functions.
7775 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7777 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7778 of allocating a new string object. Also, increase size by
7779 the factor 2 instead of 1.5.
7781 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7783 * __scm.h (SCM_P): Corrected to run under traditional C.
7785 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7788 * async.c: Calls to scm_sysintern corrected.
7790 * async.h (scm_async_clock): Redundant declaration removed.
7792 * continuations.c (scm_dynthrow): Redundant declaration removed.
7794 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7795 Definition typos corrected.
7797 * debug.h: Missing declarations of functions in debug.c added
7800 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7801 Missing declarations to functions in eval.c added.
7803 * filesys.c: Possibly uninitialized variable rv.
7805 * gc.h (scm_object_addr, scm_unhash_name): Missing
7806 declarations of functions defined in gc.c added.
7808 * genio.c: Possible typos str_data -> wstr_data. ???
7810 * genio.c: Possibly unintended shadowing of local variable
7811 `int c' (gotos out of scope of inner `c'). ???
7813 * init.c: Uninitialized `SCM last' may be used.
7815 * ioext.h: (scm_sys_isatty_p): Typo.
7817 * list.h (scm_list_head): Missing prototype for function in
7820 * numbers.c (scm_two_doubles): Changed from extern to static
7821 (is used only within numbers.c).
7823 * numbers.h: Repeated declarations removed.
7825 * ports.h (scm_close_all_ports_except): Declaration for the
7826 function defined in ports.c added.
7828 * posix.h: Missing declarations added.
7830 * procs.h (scm_make_subr_opt): Missing declaration added.
7832 * socket.h (scm_sys_gethost): Missing declaration added.
7834 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7836 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7837 Missing declarations added.
7839 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7841 * struct.c: Uninitialized variable `SCM answer' may be used.
7843 * unif.c (l2ra): Declaration prototype.
7845 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7846 defined in ramap.c).
7848 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7849 Redundant declarations removed (they are in ramap.h).
7851 * variable.h (scm_make_udvariable,
7852 scm_make_undefined_variable): Declaration corrected to
7853 correspond variable.c.
7855 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7856 Missing declarations added.
7858 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7860 * Makefile.in (distclean): Don't forget to delete fd.h.
7862 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7864 * fd.h.in, tags.h: Trivial cleanups.
7866 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7867 marksweep.h just declared functions from gc.c.
7868 * gc.h, libguile.h: Don't #include "marksweep.h".
7869 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7870 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7871 dependencies updated.
7873 * libguile.h: Don't #include "files.h"; it's been deleted.
7875 * files.c (scm_sys_delete_file): Moved to filesys.c.
7876 File is now empty; deleted.
7878 * filesys.c: scm_sys_delete_file is now here. Remove
7879 #if's; they seem to rely on remnants of an old portability
7880 regimen. If the problems come up again, solve them properly,
7881 using autoconf. Specifically: Don't test M_SYSV, and #define
7882 remove to be unlink if it's #defined; don't use remove just
7883 because HAVE_STDC_HEADERS is #defined.
7884 * filesys.h: Add declarations for scm_sys_delete_file.
7885 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7886 files.o, files.h, files.c, and files.x.
7887 * init.c: Don't #include "files.h", and don't call scm_init_files.
7889 Use SCM_P instead of PROTO; the latter intrudes on the user's
7891 * params.h: Deleted; definition of SCM_P moved to...
7892 * __scm.h: ... here, where it replaces PROTO macro.
7893 * libguile.h, smob.h: Don't #include "params.h".
7894 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7895 smob.h: Fix prototypes accordingly.
7896 * Makefile.in: Update dependencies.
7897 (inner_h_files): Remove params.h.
7899 * gc.c: #include "gc.h"; every module should include its header,
7900 to let the compiler cross-check the declarations against the
7903 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7904 simpos.h: #include "libguile/__scm.h".
7906 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7908 * init.c: Don't forget to #include smob.h and init.h.
7909 * Makefile.in: Dependencies updated.
7911 * smob.h: Use PROTO instead of #if __STDC__.
7913 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7915 * __scm.h: Doc fixes.
7917 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7918 <angles>; this allows `make depends' to work properly.
7920 * libguile.h: #include smob.h and pairs.h before the others; they
7921 define typedefs used by other headers.
7923 C files should #include only the header files they need, not
7924 libguile.h (which #includes all the header files); the pointless
7925 recompilation was wasting my time.
7926 * Makefile.in (all .o dependency lists): Regenerated.
7927 * libguile.h: Don't try to get a definition for size_t here...
7928 * __scm.h: Do it here.
7929 * _scm.h: Since this is the internal libguile header, put things
7930 here that all (or a majority) of the libguile files will want.
7931 Don't #include <libguile.h> here; that generates dependencies on
7932 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7933 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
7934 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

7970 "unif.h", "throw.h", "tag.h", "symbols.h", "struct.h",

8030 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
8031 * weaks.c: Get "weaks.h".
8033 * stackchk.h: #include "libguile/debug.h",
8035 * print.h, read.h: #include "options.h", since everyone who uses
8036 either of these files will need that.
8038 * smob.h: #include "ports.h", "genio.h", and "print.h", since
8039 anyone who uses this file will need them to define the smob
8040 printing functions. Also, get markers.h, since people will need
8041 to #define the mark functions.
8043 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
8044 * ports.h: ... to here.
8046 * ports.h (scm_port_table_size): Explicitly give type as 'int';
8047 don't rely on archaic C default type rules.
8049 * fports.h: #include "libguile/ports.h", since you need that in
8050 order to parse this.
8052 * genio.h: #include "libguile/print.h", because you need that to
8053 parse this; don't bother #including "ports.h", since print.h gets
8056 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
8058 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
8059 this; it's now a reference to an element of *scm_root.
8061 * debug.h: Don't #include "options.h"; the compiler won't be able
8062 to find that once the headers are installed; instead, #include
8063 "libguile/options.h".
8064 * gc.h: Same, with marksweep.h.
8065 * mbstrings.h: Same, with symbols.h.
8066 * scmhob.h: Same, with _scm.h.
8067 * smob.h: Same, with params.h.
8069 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
8070 C files; there's no need for this, and it forces recompilations
8073 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
8075 * error.c (scm_error): declare scm_error_callback.
8077 * error.h: prototype for scm_error_callback.
8079 * __scm.h: define lgh_error.
8080 (SCM_SYSERROR): redefine using lgh_error.
8082 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
8084 * error.c (scm_error): new procedure.
8086 * error.h: prototype for scm_error.
8088 * Makefile.in (install): install scmconfig.h from the current
8089 directory, not $(srcdir).
8091 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8093 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8094 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8095 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
8096 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
8097 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
8098 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8099 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8100 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8101 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8102 vports.h, weaks.h: #include "libguile/__scm.h", not
8103 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
8104 dependencies are within libguile properly.
8106 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
8108 * Makefile.in (.c.x): Simplify; there's no need to run this rule
8109 when scmconfig.h doesn't exist.
8111 * load.c (scm_sys_try_load): Correct spelling.
8113 * feature.c (scm_loc_features): Make this static.
8115 * Makefile.in (libpath.h): Omit trailing slash from path. We
8116 shouldn't require it of users, so why put it here?
8118 Move code to initialize and search %load-path from ice-9 to C
8119 code, so we can use the load-path to find the ice-9 boot code;
8120 this makes it easier to run Guile without installing it. See
8121 corresponding changes in guile/Makefile.in.
8122 * feature.c: Move stuff concerned with the load path to load.c.
8123 (scm_compiled_library_path): Deleted.
8124 Don't #include libpath.h here.
8125 * feature.h: Don't mention scm_compiled_library_path.
8126 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
8127 <sys/stat.h>, and <unistd.h> (if present).
8128 (R_OK): #define if the system hasn't deigned to.
8129 (scm_loc_load_path): New variable.
8130 (scm_init_load_path, scm_sys_search_load_path,
8131 scm_sys_try_load_path): New functions.
8132 (scm_init_load): Initialize scm_loc_load_path to point to the
8133 value cell of the Scheme %load-path variable.
8134 * load.h: Add declarations for scm_sys_search_load_path,
8135 scm_sys_try_load_path.
8136 * init.c: Call scm_init_load_path.
8137 * Makefile.in (feature.o, load.o): Dependencies updated.
8139 * load.c, load.h: Rewrite using PROTO macro.
8141 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8143 * gc.c (scm_cellp): New function: C predicate to determine if an
8144 SCM value can be regarded as a pointer to a cell on the heap.
8146 * gc.h: Added declaration of scm_cellp.
8148 * gdb_interface.h: New file: The GDB interface header from the GDB
8151 * gdbint.c: New file: GDB interface.
8153 * gdbint.h: New file: GDB interface.
8155 * libguile.h: Added #include <libguile/gdbint.h>.
8157 * init.c (scm_boot_guile): Added scm_init_gdbint.
8159 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
8160 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
8161 found if object files and source are kept separate).
8163 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
8165 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
8167 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
8169 * configure.in: Don't substitute the values of TCL_SRC_DIR and
8170 TK_SRC_DIR; they're not relevant any more.
8172 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
8173 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
8175 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
8177 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
8178 search path, so we can find the <libguile/MUMBLE.h> headers.
8180 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
8182 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
8183 implicit in the .c.o rule.
8184 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
8187 Put the library path in a header file, instead of passing it on
8188 the command line in every compilation.
8189 * Makefile.in (libpath.h): New target.
8190 (feature.o): Depend on libpath.h.
8191 (clean): Delete libpath.h.
8192 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
8193 * feature.c: ... #include "libpath.h" here.
8194 * .cvsignore: Ignore libpath.h.
8196 Don't install the unwashed masses of Guile header files in the
8197 main #include path; put most of them in a subdirectory called
8198 'libguile'. This avoids naming conflicts between Guile header
8199 files and system header files (of which there were a few).
8200 * Makefile.in (pkgincludedir): Deleted.
8201 (innerincludedir): New variable; this and $(includedir) are enough.
8202 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
8203 (installed_h_files): Divide this up. Now this variable lists
8204 those header files which should go into $(includedir) (i.e. appear
8205 directly in the #include path), and ...
8206 (inner_h_files): ... this new variable says which files appear in
8207 a subdirectory, and are referred to as <libguile/mumble.h>.
8208 (h_files): List them both.
8209 (install): Create innerincludedir, not pkgincludedir. Put
8210 the installed_h_files and inner_h_files in their proper places.
8211 (uninstall): Corresponding changes.
8212 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
8213 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
8214 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
8215 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
8216 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
8217 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
8218 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
8219 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
8220 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
8221 vports.h, weaks.h: Find __scm.h in its new location.
8222 * __scm.h: Find scmconfig.h and tags.h in their new locations
8223 (they're both "inner" files).
8225 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
8227 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
8229 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
8231 * posix.c: Doc fixes.
8233 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
8235 * socket.c: Don't include a prototype for inet_aton; just use a
8236 K&R style declaration, to avoid warnings but minimize the chance
8237 of conflicts with the system.
8239 On NextStep, <utime.h> doesn't define struct utime, unless we
8240 #define _POSIX_SOURCE before #including it.
8241 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
8242 * acconfig.h: New comment text for above CPP symbol.
8243 * configure.in: Call it.
8244 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8246 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8248 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8249 testing for __EMX__.
8251 * posix.c: #include <libc.h>, if it exists.
8253 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8254 don't even know if the latter exists.
8256 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8257 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8258 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8260 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8262 (scm_init_posix): Use them when initializing the Scheme constants
8265 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8267 * Makefile.in (libdir, includedir, bindir): Use the
8268 autoconf-supplied values, instead of deriving them ourselves.
8269 (pkgincludedir, datadir, pkgdatadir): New variables.
8270 (install, uninstall): Put the header files in a special
8271 subdirectory, not in the main search path.
8273 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8274 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8276 * Makefile.in (IMPLPATH): Deleted; never used.
8278 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8279 on the Tcl/Tk source any more.
8280 (INCLUDE_CFLAGS): Remove references to the above.
8282 * Makefile.in (version.o): Corrected dependencies.
8284 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8286 * libguile.h: #include "version.h"
8288 * init.c (scm_boot_guile): Call scm_init_version.
8289 * gscm.c (gscm_run_scm): Call scm_init_version.
8291 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8292 GUILE_VERSION): AC_DEFINE these.
8293 (acconfig.h): #undef the above symbols.
8295 * Makefile.in (libobjs): Add version.o.
8296 (installed_h_files): Add version.h.
8297 (c_files): Add version.c.
8298 (gen_c_files): Add version.x.
8299 (version.o): New rule.
8300 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8301 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
8302 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
8303 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
8304 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
8305 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
8306 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
8307 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
8308 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
8309 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
8310 weaks.o): Add version.h to dependency lists.
8311 (markers.o): Remove duplicate rule.
8313 * version.h: New file.
8315 * version.c: New file.
8317 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8319 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8320 array; use it appropriately. Since GCC is quite happy to
8321 subscript functions, it never warned us about this; we should use
8322 -Wpointer-arith in the future. I guess we never tested
8325 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8327 * socket.c: Doc and copyright fixes.
8329 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8331 * debug.c: Fixed and improved gdb support.
8333 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8335 * socket.c: Added declaration of inet_aton to avoid compiler
8336 warning. (Hope this solution is correct.)
8338 * stime.c: Added declaration of ftime. (This is missing in
8341 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
8343 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8345 * Makefile.in (c_files): add strerror.c.
8347 * strerror.c: new file from Emacs' sysdep.c.
8348 maybe configure should also check for sys_errlist.
8350 * configure.in (AC_REPLACE_FUNCS): add strerror.
8352 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8354 * debug.c (scm_init_debug): Added initialization for
8355 scm_evaluator_traps.
8357 * debug.h, debug.c: Various name changes.
8358 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
8359 "debug-options-interface". See commentary in options.c.
8361 * options.h, options.c: Options now have documentation strings.
8362 Also added a long explanatory commentary.
8364 * eval.c, print.h, print.c, read.h, read.c: Modifications to
8367 * gscm.c, init.c, root.c, throw.c: Bug fixes:
8368 last_debug_info_frame is now updated in all cases.
8370 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
8373 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8375 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
8376 Added option STACK_CHECKING.
8378 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8380 * Makefile.in: Added {debug,options,srcprop}.{h,c}
8382 * __scm.h: Removed symbols for debugging support.
8384 * acconfig.h: Added symbols for debugging support.
8386 * configure.in: Added user option for debugging support.
8387 --enable-debug will include the debugging code into libguile.a.
8389 * continuations.c (scm_make_cont): Enlarged the #if 0 around
8390 scm_relocate_chunk_to_heap.
8392 * debug.c: New file: low-level debugging support. It also
8393 includes support for debugging with gdb. (The extensions to gdb
8394 are written by Per Bothner at Cygnus.)
8396 * debug.h: New file: low-level debugging support.
8398 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
8399 argument pairs. Extensive modifications to the debugging
8400 evaluator. Added "SECTION:" commentaries to clarify what happens
8401 when, during double compilation. Renamed EVALIMP --> EVALIM.
8402 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
8403 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
8404 the beginning of the file. New procedure: scm_unmemocopy.
8405 Added some global state variables needed by the debugging
8406 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
8407 check_entry, check_apply, check_exit, debug_options and
8408 evaluator_traps. New acro: undefine.
8410 * eval.h: Renamed EVAL --> XEVAL.
8412 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
8413 --> scm_make_weak_key_hash_table.
8415 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
8416 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
8418 * libguile.h: Conditionally include debug.h
8420 * objprop.c (scm_object_properties, scm_set_object_properties_x):
8421 scm_object_properties shouldn't return handle. `handle' now gets
8422 initialized in scm_set_object_properties_x. scm_object_properties
8423 doesn't any longer create an entry in scm_object_whash.
8425 * options.c: New file: handling of run time options.
8427 * options.h: New file: handling of run time options.
8429 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
8431 * print.c: New procedure: scm_print_options
8433 * print.h: Defines for print options.
8435 * read.c: New procedure: scm_read_options
8437 * read.h: Defines for reader options.
8439 * root.h: Added scm_source_whash among scm_sys_protects.
8441 * srcprop.c: New file: source properties.
8443 * srcprop.h: New file: source properties.
8445 * throw.c (jbsmob): Jump buffers are now correctly allocated.
8446 (Bug found by A. Green.)
8448 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8450 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8452 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
8454 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8456 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8457 and should be called by the final client.
8459 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8461 * gc.h: Use the PROTO macro when declaring functions.
8462 * gc.c: Use the PROTO macro when declaring static functions.
8463 Remove the CPP hair around function definitions.
8465 * gc.c (scm_init_storage): Initialize scm_asyncs.
8467 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8468 preprocessor symbol; "__scm.h" is where it might get #defined.
8469 * __scm.h: Similar: #include <scmconfig.h> before testing
8472 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8474 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8476 * init.c (scm_boot_guile): Add init_func argument; call
8477 (*init_func) instead of calling scm_appinit; it's ucky to
8478 hard-code names for the user's procedures.
8479 * init.h (scm_boot_guile): Adjust declaration.
8481 * __scm.h (PROTO): New macro, for declaring functions with
8484 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8485 eliminate all the __STDC__ conditionals.
8486 (scm_boot_guile): Add declaration.
8487 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8488 Remove __STDC__ conditionals around function definitions; the
8489 declarations in init.h will provide the same information, more
8492 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8493 complain about it in the error message; the error message is
8494 adequate without that note, and there's nothing the user can do
8497 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8499 * Makefile.in (ancillary): Drop def.sed.
8501 * posix.c (scm_init_posix): Use numeric values, rather than
8502 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8503 F_OK. The symbols aren't available on some systems, and I'm
8504 pretty sure their values are fixed by common widespread practice.
8505 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8507 More functions unavailable on some systems.
8508 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8509 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8511 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8512 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8513 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8514 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8515 stub that signals an error as the #else.
8517 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8519 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8521 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8523 * unif.c: include ramap.h.
8525 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8527 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8529 * ports.c: include sys/ioctl.h.
8531 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8533 * configure.in: check for sys/ioctl.h.
8535 * ports.c: include <malloc.h> not "malloc.h".
8537 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8539 * fports.c: remove ttyname and tmpnam declarations.
8541 * posix.c: fewer ttyname declarations.
8543 * fports.c: include <string.h> not "string.h".
8545 * init.c, ioext.c: include string.h and unistd.h.
8547 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8549 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8550 genio.c, simpos.c, vports.c: include string.h.
8552 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8554 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8556 (scm_addr_buffer_size): change type from scm_sizet to int.
8557 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8558 from scm_sizet to int.
8560 * error.c: include unistd.h.
8562 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8565 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8567 * __scm.hd, def.sed: deleted.
8569 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8571 Changes for NeXT, suggested by Robert Brown.
8572 * configure.in: Call AC_TYPE_MODE_T.
8573 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8574 NeXT. Put header file list in alphabetical order.
8575 * configure, scmconfig.h.in: Regenerated.
8576 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8578 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8581 * acconfig.h: New file, providing documentation for the CPP
8582 symbols defined in configure.in
8583 * acconfig-1.5.h: Removed; superceded by the above.
8585 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8587 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8589 * fports.c (scm_open_file): don't return #f, throw error.
8591 * ioext.c (fileno): renamed from %fileno.
8592 (soft-fileno): deleted.
8594 * ports.c (scm_port_revealed): don't need to check for -1 from
8596 (scm_set_port_revealed_x): return unspecified, not #f.
8598 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8600 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8602 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8604 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8606 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8608 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8609 This is necessary on Ultrix, and doesn't hurt portability.
8611 * Makefile.in (dist-dir): New target, implementing a new dist system.
8612 (installed_h_files): Put in alphabetical order.
8613 Remove duplicate entries for markers.h and unif.h.
8614 (c_files): Remove duplicate entries for markers.c.
8615 (ancillary): Renamed from anillery; all uses changed. Remove
8616 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8617 Remove all the ../doc/* files; doc/Makefile.in handles that.
8619 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8621 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8622 every if must have an else, or else the whole command has a
8623 non-zero exit code whenever the if's condition is false.
8625 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8627 * posix.c: include string.h.
8629 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8631 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8634 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8635 Remove leading % from scheme names.
8636 Do not return error values, call SCM_SYSERROR or similar.
8638 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8640 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8642 * struct.c (scm_init_struct): new file.
8644 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8646 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8647 (scm_list_head): added list-head for rapidly chopping argument
8648 lists off of longer lists (and similar).
8650 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
8652 * objprop.c (scm_object_property): assq the cdr of the whash
8653 handle for obj, not the handle itself.
8655 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8657 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8658 weak hash tables last of all marking to avoid an obscure gc bug.
8659 WARNING: circular lists stored in a weak hash table will hose us.
8661 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8663 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8664 new functions similar to scm_substring_move_left_x and
8665 scm_substring_move_right_x.
8667 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8669 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
8672 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
8674 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8676 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8678 * strports.c (scm_strprint_obj): convenience function. C for
8679 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8681 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8682 removed to a separate library
8684 * init.c (scm_boot_guile): copied from guile-tcl.c.
8685 Initialization specific to tcl interpreters removed.
8687 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8689 * ports.c (scm_ports_prehistory): size malloced here doesn't
8690 matter so long as it is non-0 (got rid of "* 4").
8692 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8694 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8695 since its definition was bogus).
8697 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8699 * mallocs.[ch]: back again (for rx at least).
8701 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8703 * ports.c: removed functions relating to the mapping between ports
8704 and descriptors. (That stuff is unix-specific and should be collected
8705 in a separate library).
8707 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
8708 (Tom Mckay@avanticorp.com)
8710 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
8712 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8713 handled correctly (SCM_FREEP was applied to them) -- test for
8714 NIMP. Keys in weak hash tables were spuriously (though harmlessly)
8715 being overwritten with #f. (brown@grettir.bibliotech.com)
8717 Tue Apr 2 22:25:00 1996 Tom Lord <lord@beehive>
8719 * gc.c (scm_unhash_name): new procedure, unhash-name, flushes glocs
8720 for a specific symbol or for all symbols.
8722 Mon Apr 1 10:34:55 1996 Tom Lord <lord@beehive>
8724 * gc.c (scm_gc_mark): mark weak hash tables correctly (was getting weak
8725 keys and weak values confused).
8727 Thu Mar 14 22:20:20 1996 Tom Lord <lord@beehive>
8729 * list.c (scm_last_pair): map '()=>'()
8731 Wed Mar 13 16:43:34 1996 Tom Lord <lord@beehive>
8733 * pairs.c, hashtab.c, list.c, alist.c append.c, sequences.c:
8734 Generalized assoc and hash-table functions.
8735 Factored pairs.c into multiple files.
8737 Fri Mar 8 14:44:39 1996 Tom Lord <lord@beehive>
8739 * gscm.c (gscm_run_scm): got rid of objprop.
8741 Fri Mar 1 10:39:52 1996 Tom Lord <lord@beehive>
8743 * genio.c (scm_getc):
8744 NOTE: fgetc may not be interruptable.
8746 * procprop.c (scm_stand_in_scm_proc):
8747 NOTE: don't use a alist here.
8748 (scm_set_procedure_properties_x): fix type checking throughout this file.
8750 * gc.c (scm_gc_sweep): free heap segments with free, not must_free.
8752 * ports.c (scm_remove_from_port_table): adjust scm_mallocated
8753 after freeing part of the port table.
8755 Thu Feb 29 16:21:17 1996 Tom Lord <lord@beehive>
8757 * strports.c (scm_mkstrport):
8758 * vports.c (scm_make_soft_port): allocate a port table entry
8759 (possibly triggering gc) before setting the tag of the corresponding
8762 * pairs.c (scm_delq_x): never throw an error.
8764 * vectors.c (scm_make_vector): made the default vector fill argument
8765 into '() (much more useful than the previous value, "#unspecified")
8767 Mon Feb 26 17:19:09 1996 Tom Lord <lord@beehive>
8769 * ports.c (scm_add_to_port_table): Added fields
8770 to port table entries: file_name, line_num, col.
8771 Update these in open_file, gen_getc and gen_ungetc.
8772 Added procedures to access those fields.

8882 initialization to fix a race condition.
8884 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
