1 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3 * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG;
4 Account for the case when second argument is unbound.
6 * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix.
7 (Thanks to Karoly Lorentey.)
9 * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove
10 isn't present. (Thanks to suzukis@file.phys.tohoku.ac.jp.)
12 * ports.c: Use ANSI C prototypes in definitions. (Thanks to
15 * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to
18 * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to
19 Bernard Urban and Ian Grant.)
21 * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version
22 again. (1.3.4 will be binary incompatible with 1.3.2 because of a
23 change in the representation of entities and operators.)
25 1999-08-29 Gary Houston <ghouston@easynet.co.uk>
27 * ports.c (scm_ungetc): bugfix: if putback_buf is NULL
28 don't allocate zero bytes (thanks to Bill Schottstaedt).
30 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
32 * procs.c (scm_setter): Converted to use generic dispatch.
34 * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized
37 * load.c (scm_search_path): Don't try extensions which already are
38 present at the end of the filename.
39 (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.)
41 * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.)
43 Cleanup and simplification of generic method dispatch.
44 Also, the quadruple representation of entity and operator
45 procedures has been replaced with single.
47 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
49 * print.c (scm_isymnames): Removed #@hash-dispatch.
51 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
52 from eval.c; Support 0 arity methods.
53 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
54 (scm_apply_generic_env): Removed.
55 Replaced slots proc0-3 with procedure.
57 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
58 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
59 SCM_OPERATOR_PROCEDURE.
60 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
61 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
63 * struct.c, struct.h: Replace 4 procedure slots with one.
64 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
66 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
69 * eval.c (scm_sym_args): Removed.
70 (SCM_CEVAL): Simplified entity application.
71 Moved dispatch code to objects.c.
73 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
75 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
77 * sort.c (closureless): Use scm_eval_body.
79 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
80 with a symbol as last form was first called normally and then via
81 `map' or some other mechanism using primitive apply, an ILOC was
84 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
86 This change extends the representation of primitive procedures
87 with more data fields, e.g. a place for documentation and true
90 * procs.c, procs.h (scm_subr_entry): New type: Stores data
91 associated with subrs.
92 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
93 SCM_SUBR_DOC): New macros.
94 (scm_subr_table): New variable.
95 (scm_mark_subr_table): New function.
97 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
99 * gc.c (scm_gc_mark): Don't mark subr names here.
100 (scm_igc): Call scm_mark_subr_table.
103 This change implements a scheme for letting a generic work as a
104 shadow for a primitive procedure. If the primitive procedure
105 can't dispatch on its arguments, control is left over to the
106 generic. Normal wrong type arg errors will be generated until the
107 user has hung the first method on the primitive.
109 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
111 * procs.c, procs.h (scm_subr_p): New function (used internally).
113 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
115 * objects.c, objects.h (scm_primitive_generic): New class.
117 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
119 * print.c (scm_iprin1): Print primitive-generics.
121 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
122 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
124 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
125 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
126 primitives). NOTE: This means that it is now *required* to use
127 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
128 obscured representation that will be removed in the future anyway,
129 so backward compatibility is no problem here).
131 * numbers.c: Converted most numeric primitives (all but bit
132 comparison operations and bit operations) to dispatch on generic
136 Better support for applying generic functions.
138 * eval.c, eval.h (scm_eval_body): New function.
140 * objects.c (scm_call_generic_0, scm_call_generic_1,
141 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
145 Optimization of the generic function dispatch mechanism.
147 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
148 called scm_memoize_method instead of doing a second lookup.
150 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
155 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
156 scm_sysintern so that the binding connected with the subr name
157 isn't cleared when we give set = 0.
160 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
162 More transparent handling of ports with print states.
164 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
165 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
166 instead of a pair of a port and a print state. We'll need to cons
167 once extra in scm_printer_apply but the type system will be
168 cleaner, it will mix better with GOOPS, and, it will be even more
169 transparent to the user.
171 * print.c (scm_get_print_state): New procedure: Given an output
172 port, return the print state associated to it in the current print
173 chain, if one exists;
174 (scm_port_with_print_state): New procedure: Associate a
175 print-state with a port.
176 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
177 (scm_printer_apply): Wrap port and pstate as a smob;
178 (print_state_printer): Removed.
180 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
182 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
185 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
186 testing (otherwise the port-print-state trick won't be transparent
187 to the user; one example where this caused problems was in the
188 (ice-9 format) module).
190 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
192 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
193 SCM_UNSPECIFIED instead of the set value.
195 1999-08-20 James Blandy <jimb@mule.m17n.org>
197 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
199 * ports.h (enum scm_port_rw_active): New enum, containing
200 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
201 zero). The debugger knows about enums, but doesn't know about
203 (typedef scm_port): Declare rw_active member to be an enum
205 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
207 * ports.c (scm_add_to_port_table): Same.
208 * strports.c (st_flush, st_end_input): Same.
210 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
211 scm_must_realloc, and scm_done_malloc as appropriate.
213 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
215 * sort.c (quicksort): Added condition to protect the algorithm
216 from crashing the interpreter if the less predicate is buggy.
218 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
220 * fports.c (fport_write): fix line-buffering mode again.
221 (scm_open_file): recognise 'l' for line-buffering.
222 (scm_setvbuf): recognise _IOLBF for line-buffering.
224 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
226 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
229 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
232 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
234 * fports.c (fport_write): use memcpy instead of strncpy, in case
235 the data contains NUL.
237 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
239 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
241 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
242 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
243 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
244 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
245 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
246 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
247 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
248 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
249 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
250 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
251 scm_sym_ as prefix for symbols.
253 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
255 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
256 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
257 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
258 scm_sym_atcall_cc): Made global.
260 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
262 * eval.c (scm_sym_args): Made global.
264 * objects.c (scm_set_object_procedure_x): Disallow setting of
265 procedures for pure generic functions.
267 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
269 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
270 Scheme name from lseek to seek, but lseek was added recently so
271 it shouldn't be a big problem.
272 * ports.c, gdbint.c, ioext.c: changed callers.
274 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
276 * fports.c (fport_input_waiting): if select is used, return 1
277 instead of whatever FD_ISSET expands to. maybe it will be useful
278 to interpret the value from the input_waiting ptob procedure as a
279 lower bound on the number of bytes available.
281 * Mikael asked for a few names to be changed...
283 * ports.c (scm_make_port_type): take the write procedure as the
284 second argument instead of the flush procedure.
285 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
286 fflush -> flush, read_flush -> end_input, fclose -> close,
287 fill_buffer -> fill_input, ftruncate -> truncate,
288 input_waiting_p -> input_waiting.
290 * ports.c (end_input_void_port): was read_flush_void_port.
291 (scm_set_port_end_input): was scm_set_port_flush_input.
292 (scm_set_port_flush): was scm_set_port_write.
293 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
294 (scm_end_input): was scm_read_flush.
295 (scm_fill_input): was scm_fill_buffer.
296 (scm_flush): was scm_fflush.
297 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
298 (fport_end_input): was local_read_flush.
299 (fport_flush): was local_fflush.
300 (fport_close): was local_fclose.
301 (fport_truncate): was local_ftruncate.
302 (fport_seek): was local_seek.
303 (fport_free): was local_free.
304 (fport_fill_input): was fport_fill_buffer.
305 * strports.c (st_end_input): was st_read_flush.
306 (st_truncate): was st_ftruncate.
307 * vports.c: (sf_flush): was sfflush.
308 (sf_close): was sfclose.
309 (sf_fill_input): was sf_fill_buffer.
311 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
314 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
316 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
317 forms now contain the expressions to be dispatched upon instead of
318 depending on a surrounding lambda or let; Generic function
319 dispatch has been optimized; `apply' on a generic function now
320 works a little bit strangely. It uses a trick so that the type
321 dispatch code in SCM_CEVAL can be reused.
323 * objects.h, objects.c (scm_apply_generic_env): Added (used by
325 (scm_operator_p): Added.
326 (scm_sym_atdispatch): Added.
327 (scm_set_object_procedure_x): Modified to handle the new style
329 (scm_object_procedures): New debugging procedure.
331 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
333 * eval.c, eval.h (scm_sym_args): Added.
335 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
337 * feature.c, feature.h (scm_c_run_hook): Added.
339 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
340 cdrxnoap and loopnoap instead of begin and loop.
342 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
344 * ports.c (scm_putc, scm_puts),
345 * unif.c (scm_uniform_array_write): use scm_lfwrite.
346 * ports.c (scm_putc): change type of first argument from int to char.
348 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
350 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
351 SCM_IM_HASH_DISPATCH.
353 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
354 (scm_si_redfined, scm_si_hashsets): Moved.
356 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
357 flag which combines type and status info so that the class
358 redefinition protocol has zero cost during normal execution.
360 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
362 * ports.h (scm_ptob_descriptor): include a write procedure again.
363 it's more efficient for unbuffered fports (e.g., sockets.)
365 * ports.c (scm_puts): use ptob->write.
366 * vports.c (scm_make_sfptob): set write proc in ptob.
367 * strports.c (scm_make_stptob): set write proc in ptob.
368 * ports.c (write_void_port): new procedure.
369 * vports.c (sf_write): new procedure.
370 * ports.c (scm_lfwrite): use ptob->write.
371 * strports.c (st_write): new procedure.
372 * fports.c (fport_write): new procedure.
373 (scm_make_fptob): set write in ptob to fport_write.
374 * ports.h: prototype for scm_set_port_write.
375 * ports.c (scm_make_port_type): initialise ptob write procedure.
376 (scm_set_port_write): new proc.
378 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
380 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
381 until we've verified that it is actually a port. (Thanks to
384 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
386 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
387 code, particularly an unnecessary test (len != size, where len ==
388 size). (Was this leftovers from debugging code, or have I missed
391 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
392 size. (Thanks to James Dean Palmer.)
394 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
395 (Thanks to Lorentey Karoly.)
397 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
399 * eval.c (scm_m_expand_body): Use scm_cons_source.
401 * struct.c (scm_print_struct): Use vtable name.
403 * print.c (scm_init_print): Set name of print state type.
405 * stacks.c (scm_init_stacks): Set name of stack type.
407 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
409 * eval.c (SCM_CEVAL): Removed old implementation of internal
412 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
414 * debug.c, debug.h (scm_reverse_lookup): Added.
415 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
416 internal procedure definitions; Don't use scm_i_inner_name.
418 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
421 * eval.h: Added prototypes for multi language support functions.
423 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
424 improper lists in the low-level representation, since that will
425 cause a begin to be prepended at macro expansion.
427 * eval.c (scm_cons_source): Version of cons which copies source
428 properties from an existing cell.
429 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
431 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
432 procedure source before calling scm_unmemocopy instead of faking
435 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
437 Ported `internal defines' fix from SCM. Original ChangeLog entry:
439 1998-07-09 Radey Shouman <radey@colorage.com>
441 * eval.c (ceval_1): Modifications to allow rewriting of interal
442 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
443 body of which it is the CAR is macro expanded by m_expand_body,
444 which rewrites internal DEFINE.
446 (m_expand_body): Added.
448 (m_macroexp1): Added argument to control error checking:
449 m_expand_body may speculatively expand forms in the wrong
450 environments. Made argument number checks conditional on
453 (m_body): Added, error checks bodies and inserts the ISYM tokens.
455 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
458 (m_cond): (m_case): (m_quote): Modified to avoid destructively
459 changing their argument forms. Since m_expand_body
460 speculatively macro expands forms the process must be
463 (m_ident_eqp): Fixed to use proper environment.
465 (renamed_ident): Added DEFER_INTS_EGC.
467 Added prototypes for static functions.
473 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
474 is false, do not produce an error for unbound variables, return a
475 pointer to cell_undef instead.
477 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
481 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
482 destructively changing their argument forms. Since m_expand_body
483 speculatively macro expands forms the process must be reversible.
485 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
486 SCM_IM_LET introduced by named lets.
488 (scm_m_letstar): Use scm_m_body instead of bodycheck.
490 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
491 scm_letrec. scm_letrec1 does not check for a null binding and
492 takes an additional argument to specify the ISYM of the body. Use
493 scm_m_body instead of bodycheck.
495 (scm_m_let): Use scm_m_body instead of bodycheck.
497 (scm_m_expand_body, scm_macroexp): New.
499 (unmemocopy): Account for ISYMs introduced by scm_m_body.
501 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
502 check=1. Throw error for internal defined that have not been
503 rewritten by scm_m_expand_body.
505 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
506 Removed prototype for SCM_APPLY.
508 * tags.h: Added extern declaration of scm_isymnames.
510 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
512 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
514 * lang.c: New file: Beginning of multi-language support.
516 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
518 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
519 (scm_dynamic_wind): Added argument checking for the after guard so
520 that we don't add garbage on the dynwind chain.
521 (scm_swap_bindings): Added.
523 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
524 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
525 (scm_isymnames): New isyms for multi-language support.
527 * eval.c (scm_nil, scm_t): New symbols.
528 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
529 forms for multi-language support.
531 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
533 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
535 Renamed functions in the random function library interface
536 from scm_i_XXX --> scm_c_XXX.
538 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
540 * ports.c (scm_putc): fix line-buffering.
542 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
544 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
545 scm_set_ptob_XXX --> scm_set_port_XXX.
547 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
549 * ports.c, ports.h (scm_make_port_type): New interface for
550 creation of port types (replaces scm_newptob). Just as for the
551 smobs, we need to separate the internal representation of smob
552 types from the interface, so that we easily can add new fields and
553 rearrange things without caring about backward compatibility.
554 This change was forced by the need in GOOPS to create classes
555 representing port types.
556 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
557 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,

566 (void_port_ptob, print_void_port, close_void_port, noop0):
567 Removed. Removed #include "genio.h" Added #include "objects.h",
570 * fports.c (prinfport): Moved code from ports.c.
572 (scm_fptob): Removed. Instead use new interface.

577 (scm_make_stptob): Added.
579 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.

627 * guardians.c (scm_guardian_zombify): Separate scanning for
628 zombies from marking the pairs of the free list.

634 lambda. Let your sins be purified by the blood of the lambda.
635 (Thanks to Eric Hanchrow.)

645 * stime.c (ftime): Delete declaration for this function --- let
646 the system supply it.
648 Cleanups from John Bley.
650 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
652 * gsubr.c: Don't include "gsubr.h" twice.
654 Cleanups for compilation on Irix 6, from David Kaelbling.
656 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
657 regex_t pointer. This is what the callers have, mostly.
658 (scm_regexp_exec): Don't forget to pass the `rx' argument to
659 scm_regexp_error_msg.
661 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
662 int. That way, if we get a warning on this line, it's more likely
663 that we're really missing bits we care about.
665 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
668 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
669 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
670 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
671 cast at all is more appropriate in every case. At the moment, we
672 assume everywhere that SCM is an integral type anyway.

683 fports.c (fport_fill_buffer): implement the interface change.
685 * ports.c (scm_fill_buffer): interface change: no longer increments
686 read_pos past the character that's returned. it seems clearer to
687 leave it to the caller to decide what to do (thanks Jim).
689 * vports.c (sf_fill_buffer): put the read char into the buffer
690 as well as returning it.
692 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure

706 * ports.c (scm_ftruncate): throw error if offset works out negative.
708 * strports.c (st_flush): increase string size in blocks of
709 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
710 it's greater and reset read_buf_size.
711 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
712 to be maintained for output ports too (it holds the written
713 part of the string, while write_buf may have unwritten buffer
715 (st_truncate): rewritten.
716 (top of file): added a few notes.
718 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
720 Patch from Greg Badros:
721 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
722 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
723 (function pointer) argument to scm_make_gsubr and scm_make_subr
724 calls. This avoids warnings in C++ programs using guile-snarf.
726 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
728 * strports.c (st_grow_port): set pt->read_pos. set
729 pt->read_buf_size one less than pt->write_buf_size if there's
730 an unwritten char at the end of the string. similarly for
732 (st_resize_port): renamed from st_grow_port.
733 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.

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

852 * struct.c, struct.h:
854 In order to support different kinds of deallocation, a destructor
855 slot has been added to struct vtables. This allows for structs

1011 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
1013 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
1014 it shows up as terrible performance, as we GC constantly.

1061 instead of in ioext.c.
1062 strports.c (scm_call_with_output_string): start with an empty
1063 string, so seek and ftruncate can be used.
1065 gdbint.c: adjust string port usage.
1067 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1069 * ports.h (scm_ptobfuns): add a read_flush procedure which is the

1076 fports.h (struct scm_fport): remove random member. there's nothing
1077 left but fdes. leaving it as a struct to allow for future changes.
1078 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
1079 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
1080 ptob proc if the read buffer is filled.
1082 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
1084 * ports.h (scm_port): add a rw_random member and replace
1085 reading and writing members with rw_active member.
1086 SCM_PORT_READ/SCM_PORT_WRITE: new values.
1088 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
1090 * ports.h (struct scm_port_table): add writing and reading members
1091 to replace write_needs_seek: it isn't good enough for non-fports.
1092 ports.c, ioext.c, fports.c: corresponding changes.
1093 (struct scm_port_table): give it a typedef and rename to scm_port.
1094 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
1095 corresponding changes.
1097 1999-04-20 Gary Houston <ghouston@easynet.co.uk>
1099 * ports.c (scm_newptob): bugfix: set seek member.
1100 * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
1101 and generalised to all port types.
1103 1999-04-18 Gary Houston <ghouston@easynet.co.uk>
1105 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
1106 signals (it was only being done for handlers installed from Scheme).
1107 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
1108 waiting for input caused an EINTR error from read.
1110 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
1112 * ports.h (struct scm_port_table): make all the char members
1113 unsigned, so they convert to int without becoming negative if large.
1115 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
1117 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
1118 with threads enabled. rename this procedure to
1119 fport_wait_for_input and take a port instead of a fdes.
1120 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
1122 * readline.c (scm_readline): Applied a patch from Greg Harvey to
1123 get readline support working again: use fdopen to get FILE objects.
1125 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
1127 * gc.c (scm_init_storage): install an atexit proc to flush the
1129 (cleanup): the new proc. it sets a global variable which can be
1130 checked by the ptob flush procs to avoid trying to throw
1131 exceptions during exit. not very pleasant but it seems more reliable.
1132 * fports.c (local_fflush): check terminating variable and if set
1133 don't throw exception.
1134 * CHECKME: that the atexit proc is installed if unexec used.
1136 * throw.c (scm_handle_by_message): don't flush all ports here.
1137 it still causes bus errors.
1139 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
1140 and move to ioext.c.
1142 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
1144 * ports.c (scm_char_ready_p): check the port buffer and call the
1145 ptob entry if needed.
1147 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
1148 ptob initialisers. use it in char-ready
1150 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
1152 * vports.c (sfflush): modified to write a char (since softports
1153 currently use shortbuf.)
1155 * fports.c (scm_standard_stream_to_port): moved to init.c and
1158 * init.c (scm_init_standard_ports): make stdout and stderr
1159 unbuffered if connected to a terminal. with stdio they
1160 were line-buffered by default.
1162 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
1165 * ports.h (scm_ptobfuns): change fflush return to void.
1166 change flush proc definitions.
1168 * strports.c (scm_call_with_output_string): get size from
1169 buffer instead of port stream.
1170 (st_flush): new proc.
1172 * ports.h (struct scm_port_table): added write_end member,
1173 as an optimisation. set it where write_buf_size is set.
1175 * ports.h (struct scm_port_table): change stream from void *
1176 back to SCM. SCM presumably must be large enough to hold a
1177 pointer (and probably vice versa but who knows.)
1178 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
1180 (scm_puts): rewritten
1181 * fports.c (local_ffwrite, local_fputs): removed.
1182 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)

1187 * ports.c (scm_lfwrite): rewritten using fport.c version.
1189 * fports.c (local_fputc): deleted.
1191 * ports.c (scm_add_to_port_table): initialise write_needs_seek.
1193 * ports.h (scm_ptobfuns): add seek function pointer.
1194 * fports.c: set it to local_seek, new procedure.
1197 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
1198 use ptob for seek. take ptob instead of fport arg.
1200 * ports.h (struct scm_port_table): new member write_needs_seek,
1201 replaces reading member in fport struct.
1203 * vports.c (sfgetc): store the getted char into the buffer.
1204 rename to sf_fill_buffer and install it for fill-buffer in ptob.
1205 the Scheme interface is still a procedure that gets a char.
1206 (scm_make_soft_port): set up the port buffer (shortbuf).
1208 * fports.c (local_fgetc, local_fgets): deleted.
1209 * strports.c (stgetc): likewise.

1213 * ports.c (scm_newptob): assign it.
1214 * strports.c (scm_mkstrport): set up the buffer.
1215 put just the string into the stream, not cons (pos stream).
1216 (stfill_buffer): new proc.
1218 * ports.h: fport buffer moved into port table: to be
1219 used for all port types.

1364 buffer support removed. take SCM arg, not FILE *.

1418 * strop.c (scm_substring_move_x): New function, which can handle
1419 arbitrary overlapping substrings.
1420 (substring-move-left!, substring-move-right!): These are
1421 now just synonyms for substring-move!.

1494 1999-03-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1496 * numbers.c (isfinite): Define this macro if not defined: Return a
1497 non-zero value if X is finite. (From ISO C 9x standard.)

1539 * error.c (scm_wta): Pass SCM_LIST1 (arg) instead of SCM_EOL to
1540 scm_misc_error when pos is a string. This allows for dispatching
1541 arbitrary error messages with one argument via SCM_ASSERT:

1550 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1552 Most of this batch of changes is about how to deal with extended
1553 types when an object system is loaded into Guile. A nice object
1554 system is capable of representing Guile's types as class objects.
1556 For example, we want a regular expression to be of class <regex>.
1557 But regular expressions are smobs which aren't under direct
1558 control of the object system, so there has to be some mechanism
1559 which informs the object system that a new class should be created
1560 which can represent the smob type. I call this a "wrapper class".
1562 * objects.c: #include "smob.h";
1563 (scm_class_keyword): Removed. (Class is automatically created by
1565 (scm_smob_class): Array of smob classes indexed by smobnum.
1566 (scm_make_extended_class): "Plugin" function pointer for creation
1567 of wrapper classes for smob and struct types.
1568 (scm_class_of): Handle compiled closures. (Currently regarded as
1570 Use scm_smob_class to handle smob types;
1571 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword

1586 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1587 for accessing names of vtables. The record implementation in
1588 boot-9.scm currently uses the setter to record the name of record
1589 types. When the object system is initialized, it can use this
1590 information to create wrapper classes with suitable names.
1591 (scm_init_struct): Allocate scm_struct_table.
1592 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.

1607 hash table (in no particular order).
1609 Argh! For the umpteenth time I got compilation errors because of
1610 the "intuitive" name `kw'. This has to have an end:
1612 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1613 "kw" --> "keywords" everywhere.
1614 (I doubt that this will cause big compatibility problems since the
1615 application interface is unaffected.)

1768 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1770 * print.c (scm_iprin1): Use scm_procedure_name instead of
1771 scm_procedure_property for compiled closures.
1773 * tags.h (scm_tc7_pws): New procedure type. Four representations
1774 for procedure-with-setters were considered before selecting this
1777 1. A closure where the CODE and ENV slots are used to represent
1778 the getter and a new SETTER slot is used for the setter. The
1779 original getter is stored as a `getter' procedure property. For
1780 closure getters, the CODE and ENV slots contains a copy of the
1781 getter's CODE and ENV slots. For subr getters, the CODE contains
1784 2. A compiled closure with a call to the getter in the cclo
1785 procedure. The getter and setter are stored in slots 1 and 2.
1787 3. An entity (i.e. a struct with an associated procedure) with a
1788 call to the getter in the entity procedure and the setter stored
1789 in slot 0. The original getter is stored in slot 1.
1791 4. A new primitive procedure type supported in the evaluator. The
1792 getter and setter are stored in a GETTER and SETTER slot. A call
1793 to this procedure type results in a retrieval of the getter and a
1794 jump back to the correct eval dispatcher.
1796 Representation 4 was selected because of efficiency and
1799 Rep 1 has the advantage that there is zero penalty for closure
1800 getters, but primitive getters will get considerable overhead
1801 because the procedure-with-getter will be a closure which calls
1804 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1805 <procedure-with-setter>, but together with rep 2 it suffers from a
1806 three level dispatch for non-GOOPS getters:
1808 cclo/struct --> dispatch proc --> getter
1810 This is because the dispatch procedure must take an extra initial
1811 argument (cclo for rep 2, struct for rep 3).
1813 Rep 4 has the single disadvantage that it uses up one tc7 type
1814 code, but the plan for uniform vectors will very likely free tc7
1815 codes, so this is probably no big problem. Also note that the
1816 GETTER and SETTER slots can live directly on the heap, using the
1817 new four-word cells.
1819 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,

2077 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
2078 (scm_make_named_hook): New function.
2080 * feature.c: Added #include "eval.h".
2082 * modules.c (scm_make_module): Beautify the module.
2084 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2086 * modules.c, modules.h: New files: C interface to modules. (This
2087 is necessary in order to interface the object system to Guile
2088 properly. The guts of these modules will be replaced by the new
2089 module system in the future.)
2091 * init.c: Added #include "modules.h"
2092 (scm_boot_guile_1): Call scm_init_modules.
2093 (invoke_main_func): Call scm_post_boot_init_modules.
2095 * Makefile.am: Added modules.c, modules.x, modules.h.
2097 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
2099 * procs.c: #include "objects.h"
2100 (scm_procedure_p): Return #t also on structs which are operators.
2102 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
2103 <operator-metaclass> and <entity-class> to <standard-class>,
2104 <operator-class> and <entity> in order to conform with STKlos
2107 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
2108 which isn't an operator.
2109 (SCM_APPLY): Ditto, but jump to badproc.
2111 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
2113 * eval.c (SCM_CEVAL): Allow structs implanted in code.
2114 Previously, structs implanted in code were interpreted as forms
2115 the operator of which was a gloc. We solve this by checking for
2116 the zero in the emulated vcell in the struct vtable. Since
2117 implanted structs always will look like forms with a gloc
2118 operator, execution will only be slowed down by maximally one
2119 extra test-and-branch per application.
2121 * evalext.c (scm_definedp): Removed check for isyms; Added a
2122 second optional argument: It is now possible to supply an
2123 evaluation environment in which to look for the symbol.
2125 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2127 * readline.c (scm_init_readline): Set
2128 rl_basic_word_break_characters. (Thanks to Ian Grant.)
2130 * coop.c (coop_condition_variable_wait): Removed
2131 (coop_condition_variable_wait_mutex): Folded logic of
2132 coop_mutex_unlock into coop_condition_variable_wait_mutex to
2133 prevent condvar signal lossage. Previously, another thread could
2134 start to run after unlocking the mutex but before putting the
2135 current thread on the wait queue. If that thread then would
2136 signal the first, the signal would be lost. (Thanks to Christian
2139 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2141 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
2144 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2146 * objects.c (scm_i_make_class_object): Renamed from
2147 make_class_object; exported; error checking moved to
2148 scm_make_class_object and scm_make_subclass_object.
2149 (scm_make_class_object, scm_make_subclass_object): Use
2150 scm_i_make_class_object.
2151 (scm_make_subclass_object): Let the subclass have same metaclass
2154 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2156 * debug.c (scm_debug_options): Bugfix: Set the value of
2157 scm_stack_checking_enabled_p after setting debug options;
2158 #include "stackchk.h". (Thanks to Richard Polton.)
2160 1998-11-13 Radey Shouman <rshouman@metro2000.com>
2162 * unif.c (scm_array_contents): removed unnecessary test for 0
2165 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2167 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
2168 Replaced by macro `collect' in boot-9.scm.
2170 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2172 * eval.c (scm_copy_tree): Copy source properties if existent.
2174 * debug.c (scm_start_stack): Copy source when evaluating. (If we
2175 don't, we may end up passing memoized source to a transformer.)
2177 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2179 * stack.c (get_applybody): Help function which lookups the first
2180 body form of the apply closure.
2181 (read_frames): Prevent the source of the first form of the apply
2182 closure from being recorded. This would only be confusing.
2184 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
2185 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
2187 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
2189 * stacks.c (read_frame): Bugfix: Removed lingering `else'
2191 (read_frames): Use SCM_MACROEXPP.
2193 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2195 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
2196 don't contain interesting information since all arguments are
2197 present in the frame which applies the compiled closure anyway.);
2198 Skip the transformer application frames.
2200 * print.c (scm_iprin1): Print gsubrs as primitives.
2202 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2204 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
2206 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
2207 that we can identify these in a backtrace. (This change doesn't
2208 introduce any significant speed penalty.)
2210 * eval.c: Added note about `serial-map' using scm_map.
2212 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2213 readline options. They should reside in their own options array.
2215 * readline.c, readline.h (scm_readline_options,
2216 scm_readline_opts): Moved readline options here.
2218 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2220 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2221 SCM_ROCHARS instead of SCM_CHARS.
2223 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2224 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2226 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2228 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2229 This is quite important since the latter clears the
2230 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2231 every single character read...
2233 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2235 * print.c (scm_iprin1): Removed suspect looking (and indeed
2236 malevolent) semicolon after test for user supplied closure print
2237 procedure. (Thanks to Telford Tendys.)
2239 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2240 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2241 starting to search the list. Removed call to sloppy_mem_check.
2243 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2244 procedures: Same as scm_delq_x et al, but delete maximally one
2247 * options.c (scm_options, scm_init_options): GC-protect option
2248 values of type SCM. (Thanks to Telford Tendys.)
2250 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2252 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2253 make sure that there always is a "real" scm_lookupcar.
2255 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2257 * read.c, read.h (scm_read_opts): New read options
2258 "history-length" and "history-file".
2259 (scm_read_options): Stifle history to history length.
2261 * readline.c (scm_read_history, scm_write_history): New procedures.
2263 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2265 * eval.h (scm_macro_eval_x): Removed declaration.
2267 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2268 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2269 Renamed and made global.
2271 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2272 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2274 * evalext.c, evalext.h: New files. Contain non-R5RS things
2275 having to do with evaluation.
2277 * evalext.c (scm_serial_map): New procedure: Version of `map'
2278 which guarantees that the procedure is applied to the lists in
2280 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2281 returns a list of the results of the body forms instead of the
2282 result of the last body form.
2283 (scm_definedp, scm_m_undefine): Moved from eval.c
2285 * evalext.h (scm_m_sequence_to_list): Added declaration.
2287 * macros.c, macros.h: New files.
2288 (scm_procedure_to_syntax, scm_procedure_to_macro,
2289 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2290 scm_macro_name, scm_macro_transformer): Moved from eval.c
2291 (scm_make_synt): Moved from eval.c
2293 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2295 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2298 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2300 * debug.c, print.c: Added #include "macros.h".
2302 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2304 This change adds the ability to use `unread-char' multiple times
2305 without interspersed reads and adds the new procedure
2306 `unread-string'. The change is optimized for the common case of
2307 unreading a single character. This is also the reason behind the
2308 choice to store characters in the port itself: in most cases no
2309 extra malloc is required.
2311 The amount of code in some macros in ports.h has been increased to
2312 the extent that they would fit better as C functions, but, since
2313 this code belongs to the port representation, such functions
2314 should be placed in ports.c which would cause calls back and forth
2315 between ports.c and genio.c. That is not good for performance.
2316 Also, keeping them as macros allows the compiler to do some
2317 optimizations which are needed to make the current interface
2318 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2320 One benchmark (Guile startup time) indicates an increase of
2321 loading speed of 1%. Another (reading (using `read') boot-9.scm
2322 10 times) shows no change in performance.
2324 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2325 made to find a beautiful solution.)
2327 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2328 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2329 character. (SCM_CLRDY clears all.)
2330 (SCM_N_READY_CHARS): New macro: Returns number of unread
2331 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2332 (struct scm_port_table): New fields: `entry' contains port table
2333 index, `cp' points to last unread char, `cbuf' is the buffer for
2334 unread chars, `cbufend' points after end of the character buffer.
2336 * ports.h, ports.c (scm_unread_string): New procedure.
2337 (scm_grow_port_cbuf): New function.
2339 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2341 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2342 to read unread characters. Use SCM_TRY_CLRDY instead of
2345 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2347 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2349 * genio.c, genio.h (scm_ungets): New function.
2351 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2354 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2356 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2357 declarations. (Thanks to Russ McManus.)
2359 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2361 * numbers.c (num2long): As a software archeologist, I'm proud of
2362 this finding! :) Preliminary dating suggests an almost 4 year old
2363 remnant from the SCM ancestor. The sample has been removed from
2364 the finding site and is now safely stored in the repository.
2366 * numbers.h: Removed prototype for num2long.
2368 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2370 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2371 array as second arg.
2372 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2373 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2374 * gh.h: Updated and added prototypes.
2376 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2378 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2380 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2382 * guile-snarf.in: Never generate an empty file. (Thanks to
2385 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2386 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2387 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2388 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2389 gh_new_procedure5_0): Specify argument types, to appease C++
2390 compilers. (Thanks to Brad Bowman.)
2392 Bug reports from Russ McManus:
2393 * guile-snarf.in: If the CPP environment variable is set, use that
2394 as the C preprocessor, instead of the preprocessor autoconf
2396 * snarf.h (SCM_PROC): Cast the function pointer passed to
2397 scm_make_gsubr, to satisfy C++.
2399 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2400 Use the handler passed, instead of ignoring it and using
2401 gh_standard_handler. (Thanks to Etienne Bernard.)
2403 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2405 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2408 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>
2410 * __scm.h, alist.c, async.c, async.h, backtrace.h, chars.c,

2425 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
2428 * script.c (scm_compile_shell_switches): Define
2429 use-emacs-interface in the root module, so the repl code can see
2430 it. See today's change to top-repl in ice-9/boot-9.scm.
2432 * filesys.c (set_element, get_element): Make sure that `element'
2433 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2434 Boekemeier and Jorgen "forcer" Schaefer.)
2436 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2438 * chars.c (scm_charnames): In ASCII character name table, make
2439 newlines print as #\newline by default, not #\nl.
2441 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2442 alphabetical order. Oh thrills. But it helps me know how far
2443 along in the compilation I am.
2444 * Makefile.in: Regenerated.
2446 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2448 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2449 #bytes(...) to #y(...), and syntax for short vectors from
2450 #short(...) to #h(...). This may seem nutty, but, like the other
2451 uniform vectors, byte vectors and short vectors want to have the
2452 same print and read syntax (and, more basic, want to have read
2453 syntax!). Changing the read syntax to use multiple characters
2454 after the hash sign breaks with the conventions used in R5RS and
2455 the conventions used for the other uniform vectors. It also
2456 introduces complexity in the current reader, both on the C and
2457 Scheme levels. (The Right solution is probably to change the
2458 syntax and prototypes for uniform vectors entirely.)
2460 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2462 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2463 (Thanks to Jorgen "forcer" Schaefer.)
2464 * ports.h (SCM_NOFTELL): New flag.
2465 * fports.c (local_fgets): If it's set, use the generic fgets.
2466 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2468 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2470 * script.c (scm_compile_shell_switches): Add handling of -q switch
2471 (inhibit loading of user init file).
2472 (scm_shell_usage): Add usage text for -q switch.
2473 (scm_compile_shell_switches): Always load user init file first if
2474 it is loaded at all.
2476 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2478 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2479 and is now broken under NetBSD. I can't fathom what it's trying
2480 to do, so I've replaced it with something that I do understand,
2481 which seems to work, and which isn't broken on NetBSD. "Progress?
2482 You Decide." (Thanks to Perry Metzger.)
2484 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2485 signed/unsigned comparison.
2487 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2489 Warning fixes from Greg Harvey:
2490 * unif.c (scm_array_set_x): initializer for pos
2491 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2492 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2493 initializers for field_type, since EGCS so desparately wants to
2495 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2496 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2497 when GUILE_DEBUG is defined.
2498 * dynwind.h (scm_wind_chain): Same.
2499 * ports.h (scm_pt_size, scm_pt_member): Same.
2500 * print.h (scm_current_pstate): Same.
2501 * procs.h (scm_make_cclo): Same.
2503 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2505 Handle short and long long uniform arrays properly. (Thanks to
2507 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2508 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2509 scm_tc7_llvect (long long vectors).
2511 Change the way libguile and boot-9.scm are timestamped, to try to
2512 get rid of these spurious mismatch warnings. Now both
2513 libguile/versiondat.h and ice-9/version.scm are generated directly
2514 by the configuration process, rather than having version.scm
2515 generated directly, and libguile/versiondat.h generated by the
2516 Makefile, which is generated by configure. It seems that
2517 sometimes the Makefile would change, but versiondat.h depends on
2518 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2519 * Makefile.am (versiondat.h): Target removed; this is generated
2520 directly by the configure script now.
2521 (BUILT_SOURCES): Remove versiondat.h.
2522 * versiondat.h.in: New file, transformed by the configure script
2524 * Makefile.in: Regenerated.
2526 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2527 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2528 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2529 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2530 if we want to use them in a header file some day, we can. (Thanks
2531 to Michael Livshin.)
2533 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2534 SCM numbers, so we won't have rollover problems; the range of a
2535 signed long in milliseconds is about 25 days. (Thanks to Karl
2538 Don't redefine sleep and usleep; fix this problem now.
2539 * coop.c (sleep, usleep): Remove declarations; we don't use or
2540 redefine these any more.
2541 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2542 job of usleep and sleep in a thread-friendly way. We can use
2543 these in the rest of Guile. Define versions for systems both with
2544 and without iselect.
2545 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2546 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2547 we're just using it, not redefining it, we can use a K&R style
2549 (sleep): Declare this, too, if the system hasn't.
2550 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2551 scm_uthread_sleep if they're available; otherwise, just call the
2553 * scmconfig.h.in: Regenerated.
2555 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2557 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2559 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2561 * threads.c: Doc fix.
2563 The argument type of usleep varies from system to system,
2564 as does the return type. We really shouldn't be redefining usleep
2565 at all, but I don't have time to clean that up before the 1.3.
2566 release. It's on the schedule for afterwards. (Thanks to Julian
2568 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2570 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2571 * scmconfig.h: Regenerated.
2573 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2574 right way to handle system variation. Autoconf's approach is the
2576 * simpos.h (scm_software_type): Declaration deleted.
2578 * script.c (scm_find_executable): Don't test if unix is #defined
2579 here; first, NetBSD doesn't #define it, and second, it's the wrong
2580 way to go about these things. (Thanks to Perry Metzger.)
2581 (dld_find_executable): Delete this MSDOS support code. This isn't
2582 the way we want to support this; it needs to be rethunk at a
2585 * genio.c (scm_do_read_line): Don't just politely check that the
2586 line was either non-empty or EOF. Abort if it's empty and not
2589 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2591 * scmconfig.h.in: Regenerated.
2593 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2596 * genio.c (scm_do_read_line): Count lines correctly when the file
2597 doesn't end in a newline.
2599 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2601 * genio.c (scm_do_read_line): Maintain the line count correctly.
2602 (Thanks to Harvey J. Stein and Greg Harvey.)
2604 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2607 * numbers.c (big2str): Protect t from garbage collection until
2608 we're done. (Thanks to Gary Houston.)
2610 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2612 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2614 * Makefile.in: Regenerated.
2616 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2617 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2620 Do magic to mix reads and writes on stdio FILE-based ports.
2621 (Thanks to Christian Lynbech.)
2622 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2624 (pre_read, pre_write): New functions.
2625 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2626 local_fputs): Call them.
2627 (local_fflush): Mark the port as ready for reading and writing.
2628 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2629 flags on new port objects. This might not be accurate --- who
2630 knows what state the FILE * is in when we get it --- but it won't
2631 do extraneous calls to fflush or fseek, so it's no worse than the
2632 behavior before this change.
2633 * ports.h: Add comment.
2635 Centralize the creation of port objects based on stdio FILE * in
2636 fports.c; don't just throw them together anywhere.
2637 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2638 what the rest of Guile wants. Don't set the revealed count;
2639 that's only appropriate for stdin, stdout, stderr.
2640 (scm_standard_stream_to_port): This function does set the revealed
2642 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2643 not scm_stdio_to_port.
2644 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2645 * fports.c (scm_open_file): Same.
2646 * posix.c (scm_pipe): Same.
2647 * socket.c (scm_sock_fd_to_port): Same.
2648 * ioext.c (scm_fdopen): Same.
2649 (scm_freopen): Moved from here to...
2650 * fports.c (scm_freopen): ... here. This is really something that
2651 munges the internals of an fport, so it should go here.
2652 * fports.h (scm_stdio_to_port): Adjust prototype.
2653 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2654 * ioext.h (scm_freopen): Prototype removed.
2656 * filesys.c (set_element, get_element): This can work on both pipe
2657 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2660 * scmconfig.h.in: Regenerated.
2662 Change the definition of the functions in scm_ptobfuns so that
2663 they get passed the port object, not the port's stream.
2664 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2665 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2666 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2667 Pass the port itself to the scm_ptobs function.
2668 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2669 scm_generic_fgets): Same.
2670 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2671 getc_void_port, fgets_void_port, close_void_port): Just change the
2672 argument names; these functions don't really do anything.
2673 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2674 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2675 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2676 Also, use prototyped definitions, and get rid of the extra
2678 (scm_fptob, scm_pipob): We don't need casts here any more.
2679 * strports.c (prinstpt): Use prototype declarations.
2680 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2681 and use SCM_STREAM to get the string info. Also, use prototyped
2682 definitions, and get rid of the extra declarations.
2683 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2686 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2687 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2689 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2690 scm_fgets, for consistency.
2691 (scm_fptop, scm_pipob): References updated.
2693 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2695 Include the source location in error messages for scripts.
2696 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2697 stack is still there when we catch the error.
2698 * throw.c (handler_message): If we are handling an error with a
2699 message, then put together the proper arguments and call
2700 scm_display_error, instead of scm_display_error_message. That
2701 displays source location, if it can find it.
2703 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2705 * gc.c (scm_unprotect_object): Change this so that calls to
2706 scm_protect_object and scm_unprotect_object nest properly.
2707 (scm_protect_object): Doc fixes.
2709 * strings.c (scm_string_set_x): Require the argument to be a
2710 writable string, not a substring or a symbol.
2711 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2712 (Thanks to John Redford and Charbel Jacquin.)
2714 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2716 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2718 * eval.c (safe_setjmp): Remove this misunderstanding.
2719 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2722 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2724 * libguile.h: Mark these as C declarations, for compilation by C++
2727 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2728 __cplusplus clause. I seriously doubt this ever worked the way
2729 the author seems to have intended.
2731 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2733 Utterly needless cleanups to hopelessly messy code.
2734 * ports.c: Doc fixes.
2735 (scm_fflush): Moved to ...
2736 * genio.c (scm_fflush): ... here, amongst all the other port
2737 method invocation functions.
2738 * genio.h, ports.h: The prototype moves too.
2740 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2742 * backtrace.c (display_error_body): The current frame does not
2743 always have a parent frame; consider a function called directly
2744 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2747 * alloca.c (alloca): Undo yesterday's changes, and simply call
2748 malloc directly for storage, and abort if we don't get what we
2749 want. The situation is much simpler --- just call malloc. Emacs
2750 has bizarre/evil requirements (signal handlers might malloc unless
2751 you set this global flag, so you have to set the flag around all
2752 calls to malloc) which we are certainly not going to conform to,
2753 so we can do the simple and obvious thing.
2755 * coop.c (coop_condition_variable_wait): Make this function
2756 static. It's only useful internally --- you should never just
2757 wait on a condition variable.
2758 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2760 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2762 * unif.c (scm_array_set_x): Accept any kind of number as an
2763 element for a uniform vector of doubles. This is more consistent
2764 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2766 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2767 works; I can't conveniently test it myself. (Thanks to Dvid
2768 Tillman for the bug report.)
2770 * init.c: Doc fixes.
2772 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2773 from here, not from scm_compile_shell_switches (which is a pretty
2774 dumb place to do it).
2775 (scm_load_startup_files): New function.
2776 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2777 * script.c (scm_compile_shell_switches): Don't load the startup
2779 (scm_ice_9_already_loaded): Variable moved.
2780 * init.c (scm_load_startup_files): Prototype for new function.
2781 * gh_init.c (gh_enter): Doc fix.
2783 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2785 Some anti-warning changes from Greg Harvey.
2786 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2787 warnings when it doesn't understand our NORETURN declarations in
2789 * posix.c (scm_mknod): Similar.
2791 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2793 * posix.c (scm_getpwuid): If we can't find an entry, return our
2794 own message, instead of using scm_syserror --- the getpwMUMBLE
2795 functions don't set `errno' to anything interesting.
2797 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2799 Get rid of warnings from the cooperative threading system.
2800 * threads.h (scm_single_thread_p, scm_yield,
2801 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2802 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2803 scm_wait_condition_variable, scm_signal_condition_variable): Add
2804 prototypes for these Scheme-visible functions.
2805 * coop-defs.h (coop_next_runnable_thread,
2806 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2807 Prototypes for these here, even though they're from iselect.c.
2808 (coop_condition_variable_wait, coop_join): Add prototypes.
2809 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2810 scm_threads_free_condvar): Make these smob functions static.
2811 * coop-threads.h (coop_init): Give this a real prototype.
2812 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2813 (coop_next_runnable_thread): No need to provide prototype; it's in
2816 * scmconfig.h.in: .detarenegeR
2818 * iselect.c, threads.c: Doc fixes.
2820 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2822 * Makefile.in: Regenerated with a patched automake, to get
2823 dependency generation right when using EGCS.
2825 * inet_aton.c (inet_aton): Add prototype, to remove compiler
2826 warning. (Thanks to Robert Pluim.)
2828 * inet_aton.c (inet_aton): Reassure the compiler that the
2829 arguments to the <ctype.h> macros are all unsigned characters, not
2832 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2834 Getting rid of more warnings...
2835 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
2836 today's change to ../configure.in.
2837 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
2838 * scmconfig.h.in: Regenertaded.de.,.__
2839 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
2840 (scm_localtime, scm_mktime): Use a const char * to manipulate the
2843 * readline.c: Doc fix.
2844 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
2845 * readline.h (scm_filename_completion_function): Add prototype.
2846 (scm_init_readline): Make this into a prototype.
2848 * readline.c (scm_filename_completion_function): Use SCM_PROC to
2849 declare this, instead of calling scm_make_subr manually.
2851 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
2853 * readline.h (scm_init_readline): Add prototype for this.
2854 (scm_init_readline): Make this a real prototype.
2856 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
2858 Warning fixes from Maciej Stachowiak:
2859 * backtrace.h (scm_display_application, scm_backtrace): Add
2861 * debug.c (scm_m_start_stack): Make this function static.
2862 * fluids.h (scm_fluid_p): Add prototype.
2863 * procprop.c (scm_i_procedure_arity): Make this function static.
2864 * regex-posix.c (scm_regexp_error_msg): Make this function static.
2865 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
2866 * root.h (scm_dynamic_root): Add external prototype.
2867 * scmsigs.h (scm_usleep): Add external prototype.
2868 * script.h (scm_init_script): Use prototype, not K&R decl.
2869 * stacks.h (scm_stack_id): Add external prototype.
2870 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
2872 1998-09-30 Mark Galassi <rosalia@cygnus.com>
2874 * gh.h: took out the definitions of vset and vref, since they are
2875 replaced by the proper vector routines that correspond to the R4RS
2878 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
2880 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
2881 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
2882 third argument, a C expression that should result in a SCM value,
2883 which is used to initialize the variable. Reimplemented
2884 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
2887 * version.h (scm_libguile_config_stamp): Add prototype.
2888 (From Maciej Stachowiak.)
2890 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
2892 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
2893 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
2895 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
2897 * print.c (scm_iprin1): Rather than having one i, and using it in
2898 several places, declare a fresh i local to each block where it is
2899 used, and give it a signedness appropriate to its use in each case.
2900 (scm_iprlist): Same.
2902 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
2903 comparison warnings.
2905 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
2906 signed/unsigned clashes.
2908 * posix.h (scm_tmpnam): Added prototype.
2910 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
2911 scm_make_subclass_object): Add external prototypes.
2913 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
2914 comparison is okay here.
2916 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
2918 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
2919 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
2921 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
2924 * load.c (swap_port): Make this function static.
2926 * load.c (scm_search_path): Make max_path_len and max_ext_len
2927 unsigned, since they're compared against string sizes.
2929 * load.c (init_build_info): Make i unsigned.
2931 * ioext.h (scm_read_line): Add prototype.
2933 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
2934 scm_hash_fn_remove_x): Make hash bucket index local variable k
2935 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
2936 accurately as possible.
2938 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
2939 comparisons, and range checking to make sure those casts are
2942 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
2943 signed/unsigned comparisons.
2945 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
2946 avoid signed/unsigned comparisons.
2947 * smob.h (scm_numsmob): Change extern declaration to match.
2949 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
2950 avoid signed/unsigned comparisons.
2951 * ports.h (scm_numptob): Change extern declaration to match.
2952 (scm_current_load_port, scm_set_port_line_x,
2953 scm_set_port_column_x): New prototypes.
2955 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
2956 test code, and it causes warnings.
2958 * gh.h (gh_int2scmb, gh_uniform_vector_length,
2959 gh_uniform_vector_ref): Added prototypes.
2961 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
2962 debugging support unconditionally. That's backtrace.c, stack.c,
2963 debug.c, and srcprop.c.
2964 (EXTRA_libguile_la_SOURCES): Omit those from here.
2965 * Makefile.in: Regenerated.
2967 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2969 * options.c (scm_options): Bugfix: Allow empty list of options!
2971 * debug.c, debug.h (scm_single_step): Removed.
2972 (scm_with_traps): New procedure. This procedure could easily be
2973 written in Scheme but needs to be highly optimized.
2975 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
2977 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
2978 Check SCM_TRAPS_P before trapping.
2980 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
2982 Changes to avoid signed/unsigned comparison warnings.
2983 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
2984 (scm_gc_sweep): Make n and j local to the blocks they're used in,
2985 so they can have appropriate types for each application. Make i
2986 signed. Use initializers in some spots. I'll probably pay for
2988 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
2989 (scm_must_realloc): Make nm unsigned.
2990 (init_heap_seg): Make new_seg_index and n_new_objects signed.
2991 (scm_init_storage): Use prototype-style definition, and make the
2993 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
2994 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
2996 * filesys.c (scm_readlink): Make local vars rv and size ints, to
2997 avoid signed/unsigned comparison warnings, and because the return
2998 value of readlink may be -1. Don't bother casting the third
2999 argument to readlink.
3001 * filesys.c (scm_dirname, scm_basename): Move these to their own
3002 page, at the end of the file.
3003 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
3005 * eval.h (scm_eval_options_interface): Add external prototype for this.
3006 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
3008 * eval.c (scm_lookupcar1): Make this static.
3010 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
3011 Make these prototype declarations, not K&R-style.
3013 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
3014 unsigned comparison warning.
3016 * appinit.c: File removed. It had a single function in it, empty,
3017 whose reason for existence is explained in no documentation or
3018 comment. I think it's there as a default for some Tcl-style
3019 initialization, but Tcl abandoned that approach a while ago.
3020 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
3021 (BUILT_SOURCES): Remove appinit.x.
3022 * Makefile.in: Regenerated.
3024 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
3026 * Makefile.in: Regenerated using the last public version of
3027 automake, not the hacked Cygnus version.
3029 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
3031 Remove Totoro kludge.
3032 * Makefile.in, scmconfig.h.in: Regenerated.
3033 * init.c, readline.c: Don't check if TOTORO is #defined.
3035 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
3037 * Makefile.am: Adjust for new thread configuration system.
3038 (INCLUDES): Include the value of THREAD_CPPFLAGS.
3039 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3041 (THREAD_LIBS): Definition deleted; automake will generate such
3042 things automatically.
3043 * Makefile.in: Regenerated.
3045 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3047 Simplify smob and port marking; set the mark bit in the generic
3048 marking code, and make marker routines only responsible for
3049 turning up outgoing pointers.
3050 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3051 before calling the marking function. Don't call the marking
3052 function if it's zero.
3053 * markers.c (scm_mark0): Just return #f. This function isn't
3054 necessary at all now, but it's harmless to call it. We'll leave
3055 it in so other folks' code doesn't croak at link time.
3056 (scm_markcdr): Don't call SCM_SETGC8MARK.
3057 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3058 * dynl.c (mark_dynl_obj): Same.
3059 * root.c (mark_root): Same.
3060 * srcprop.c (marksrcprops): Same.
3061 * unif.c (markra): Same.
3062 * variable.c (scm_markvar): Same.
3063 * ports.c (scm_markstream): Same.
3064 (void_port_ptob): Specify zero for our marking function.
3065 * debug.c (debugobjsmob): Same.
3066 * dynwind.c (guardsmob): Same.
3067 * filesys.c (dir_smob): Same.
3068 * fluids.c (fluid_smob): Same.
3069 * fports.c (scm_fptob, scm_pipob): Same.
3070 * mallocs.c (mallocsmob): Same.
3071 * regex-posix.c (regex_t_smob): Same.
3072 * smob.c (freecell, flob, bigob): Same.
3073 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3074 * throw.c (jbsmob, lazy_catch_funs): Same.
3076 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3078 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3079 scm_copy_tree on code in order not to let memoized code to leak
3080 out. Thus, scm_copy_tree needs to copy vectors as well since
3081 quasiquote can introduce evaluated code also inside vector
3084 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3086 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3088 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3089 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3092 * unif.c: Say that ivect and uvect are of type signed and unsigned
3093 long instead of int in commentary so that it correctly describes
3096 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3098 * stime.c: Removed declaration of strptime. (It should be
3099 declared by the system headers. If it turns out that some systems
3100 don't, we'll handle that then.) (Thanks to Greg Troxel.)
3102 * stime.h: Renamed TIMEH --> STIMEH
3104 * backtrace.c (scm_display_error, scm_display_backtrace): In order
3105 to increase portability, don't use structure assignment.
3106 (Thanks to Nicolas Neuss.)
3108 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
3110 (finalize_fd_sets): Added empty statement after last case label.
3111 (Thanks to Nicolas Neuss.)
3113 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
3116 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
3118 * init.c, readline.c: OK, I won't have these readline.x bug
3119 reports anymore. We've had them since April. The current reason
3120 is a completely unintelligible failure of totoro.red-bean.com to
3121 do the test for rl_getc_function in libreadline correctly. This
3122 kludge overrides the test if we're on totoro so that the snapshot
3123 generation process can work.
3125 * readline.c: Define a strdup replacement if not existent on system.
3127 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3129 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
3130 This change makes scm_make_vector R5RS compatible. We cannot keep
3131 the third argument since people want to be able to deduce the form
3132 of the C function call only by looking at R5RS. (At the same time
3133 we have removed some unnecessary complexity!)
3135 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
3136 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
3137 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
3138 argument in call to scm_make_vector.
3140 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3142 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
3143 This macro is useful in applications.
3145 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3147 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
3148 (scm_parse_path, scm_search_path): New Scheme level procedures.
3150 * load.h (scm_internal_parse_path, scm_parse_path,
3151 scm_search_path): Declared.
3153 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3155 * filesys.c (dirname, basename): New procedures.
3157 * init.c (scm_boot_guile_1): Removed condition around
3160 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
3161 new data type (guards) for representation of C level guards and
3162 data on the wind chain.
3163 (scm_internal_dynamic_wind): New function.
3165 * dynwind.h: Declare scm_internal_dynamic_wind.
3167 * root.h (scm_root_state): Added scm_cur_loadp.
3169 * root.c (mark_root): Added comment about cur_loadp.
3171 * load.c: #include "dynwind.h";
3172 (scm_primitive_load): Use scm_inner_dynamic_wind to update
3175 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
3177 * ports.c (current-load-port): New procedure.
3179 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3181 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
3182 not a tty, return #f.
3184 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
3185 to Julian Satchell and Roland Kaufmann.)
3187 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
3188 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
3190 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3192 * debug.h, debug.c (scm_start_stack): New function. Implements
3193 the guts of old scm_m_start_stack.
3195 * debug.c (scm_m_start_stack): Use scm_start_stack.
3197 * init.c (scm_start_stack, scm_restart_stack): Renamed to
3198 start_stack and restart_stack. (These have static scope.)
3200 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3202 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
3203 readline functions to come in release 2.3. (Thanks to Chet
3205 (handle_errors): Use the above functions.
3207 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3209 * readline.c: Improvements for readline support: Handle errors
3210 better; Implement before-read-hook.
3212 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3214 * init.c (scm_boot_guile_1), readline.c: Test for
3215 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3216 assure that we have version >= 2.1.)
3218 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3220 * readline.c (scm_readline): Defer interrupts while we're calling
3223 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3224 away the string to add_history.
3225 (completion_function): Do completion for readline. (Thanks to
3227 (scm_filename_completion_function): New procedure: Filename
3229 (current_input_getc): New function. Use this one instead of
3230 standard getc from readline.
3232 * throw.c, throw.h (scm_handle_by_throw): New function: This
3233 handler throws errors to next handler on the dynwind chain.
3235 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3237 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3240 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3242 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3244 (scm_procedure_properties): Modified to return arity together with
3246 (scm_procedure_property): Added the read-only property `arity'.
3247 (scm_set_procedure_property_x): It is an error to set the `arity'
3250 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3251 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3253 * procprop.h (scm_sym_arity): New symbol.
3255 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3256 to set the dispatch procedure of an operator or entity object.
3258 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3259 Made procedure slots read-only.
3261 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3262 scm_tcs_cons_gloc case in zero args switch; Fixed args
3263 construction for operators in scm_tcs_cons_gloc case in two args
3266 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3268 * fluids.c: Removed use of assert.h (in order to avoid
3271 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3273 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3275 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3276 change makes the evaluator safer at the cost of evaluation speed.
3277 It handles the case when the user has added a non-immediate
3278 improper end of the application form, e.g., `(+ 0 . x)'.
3279 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3280 minimize the extra cost as much as possible. The new code is
3281 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3282 problem with structs planted directly in the code (e.g. by a
3283 macro). This no longer causes segmentation fault. (Thanks to
3286 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3287 arg `proc' in order to be able to throw errors; New argument
3290 * Removed extra #include "debug.h"
3292 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3294 * scmsigs.c: Declare usleep as returning void on some systems.
3295 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3298 * coop.c (usleep): Return void on some systems.
3300 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3302 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3304 * coop.c: Changed return type of usleep to int.
3306 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3307 isn't found in the OS.
3309 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3310 isn't enabled. (Thought that I had made this change ages ago...)
3312 * iselect.c: Declare bzero if not defined by OS.
3314 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3316 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3317 condition. (Thanks to John Tobey.)
3319 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3320 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3323 * __scm.h: Start the long-term project of moving to POSIX threads.
3324 Phase 1: Classification of all critical sections.
3325 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3326 for A sections. (See comments in __scm.h for details.)
3328 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3329 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3331 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3333 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3334 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3335 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3336 dependencies on $(srcdir)/Makefile.in
3337 $(top_builddir)/config.status in order to avoid circularity.
3339 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3340 from argc if argc was 0 initially.
3342 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3343 in generation of libpath.h.
3345 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3347 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3348 libguile from 2 to 3.
3350 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3352 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3354 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3356 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3357 scm_set_port_column_x, scm_port_filename,
3358 scm_set_port_filename_x): Removed optional arguments. Added
3359 proper argument checking.
3361 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3362 stack size in machine words.
3364 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3365 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3366 to Ole Myren Röhne.)
3368 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3370 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3371 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3373 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3376 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3377 procedure apply: Copy argument lists before pushing them unto the
3378 environment so that the environment won't get mutated due to
3379 manipulation of procedure arguments. This should perhaps be
3380 regarded as a temporary solution until someone finds a more
3381 efficient one. (Thanks to Maciej Stachowiak.)
3383 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3385 * script.c (scm_compile_shell_switches): Use "guile" as default
3386 zero arg if argc is NULL.
3388 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3390 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3391 is zero. (Thanks to Dirk Herrmann.)
3393 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3395 * ports.c (scm_add_to_port_table): First line is now line 0
3396 (was 1). (Interface changed according to suggestion by Per
3399 * backtrace.c (display_header): Add 1 to line and column numbers
3400 when presenting them to the user.
3402 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3403 from debug.c --> eval.c
3405 * eval.h, eval.c (scm_eval_options_interface): New options
3407 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3408 i.e. stacks for new threads.
3410 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3412 * eval.c (unsafe_setjmp): Removed with #if 0.
3414 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3417 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3418 to avoid compiler warnings.
3420 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3422 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3424 * throw.c (handler_message): Print message on current error port
3425 instead of default error port. (Thanks to Maciej Stachowiak.)
3427 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3429 * ports.c (scm_add_to_port_table): allocate in units of
3430 struct scm_port_table *, not struct scm_port_table.
3431 * posix.c (scm_close_pipe): remove the port from the port table
3433 Thanks to Rob Engle for both fixes.
3435 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3437 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3438 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3440 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3442 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3444 * backtrace.c (display_error_body, display_backtrace_body),
3445 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3446 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3447 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3448 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3451 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3452 don't receive the jmpbuf arg anylonger.
3453 (scm_catch): Don't accept a #f tag.
3454 (scm_throw): Check that key is a symbol.
3455 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3457 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3459 * async.c (async_pending): Removed declaration.
3461 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3463 * dynwind.c (scm_wind_chain): New debug function.
3465 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3466 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3467 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3468 extra layer of functions around the body and handler of a thread.
3469 This extra layer makes sure that the handler is called in the
3470 dynamic context of the surround (= empty dynwind list), but under
3471 the *dynamic root* of the body. We can not use the dynamic root
3472 of the surround since that root belongs to another thread => stack
3473 is not handled correctly. It may seem ugly to use this extra
3474 layer, but the extra cost in terms of execution time is really
3475 negligible compared to the total amount of time required to create
3476 a thread, and it would reduce maintainability to duplicate the
3477 crucial and complicated steps performed by cwdr.
3479 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3480 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3481 get re-enabled. The important effect of this is that interrupts
3482 are blocked during thread switching so that thread data structures
3483 don't risk getting messed up by an unfortunate signal.
3484 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3485 seems to do more aggressive optimization which actually move
3486 instructions around in these macros in a fatal way. Therefore:
3487 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3488 just superstitious...)
3489 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3490 This macro should be used instead of SCM_ASYNC_TICK since the
3491 latter doesn't do context switches any more.
3493 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3494 instead of SCM_ASYNC_TICK.
3496 * coop.c, iselect.c: Since thread switches are now performed with
3497 interrupts masked, we can't use the old mechanism of delivering
3498 signals immediately when they arrive. Signals must instead be
3499 delivered when the asyncs run *after* the end of the critical
3500 section in scm_internal_select. But this also means after context
3501 switch so that the signal will be delivered to a different thread.
3502 To avoid this, I have changed the protocol of
3503 coop_wait_for_runnable_thread and friends so that they are allowed
3504 to return the original thread. So, if a signal arrives during
3505 scm_internal_select, we won't any longer be forced do a context
3506 switch, but can remain in the same thread and deliver the signal
3509 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3510 scm_asyncs_pending and made it global.
3512 * iselect.c: Small fixes.
3514 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3515 coop_condition_variable_init, coop_condition_variable_wait,
3516 coop_condition_variable_signal): Changed return type from `void'
3517 to `int'. This is to adhere closer to the pthreads interface.
3518 This, in turn, is part of an attempt to provide C versions of the
3519 mutex and condition variable primitives which can be part of a
3520 frontend to COOP or pthreads.
3522 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3523 coop_condition_variable_destroy): New functions.
3525 * coop-threads.c (scm_wait_condition_variable): Use
3526 coop_condition_variable_wait_mutex.
3528 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3529 Definitions moved to coop-defs.h.
3531 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3532 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3533 scm_cond_destroy): New C interface to mutecis and cond vars.
3535 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3537 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3539 * iselect.c: Now several threads can wait on the same file
3540 descriptor. The behaviour is compatible with OS select: All
3541 threads waiting for the fd return with the same status.
3543 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3545 * coop-threads.c, threads.h (scm_spawn_thread): New function.

3548 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3550 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3551 gh_doubles2scm): New functions.
3553 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3555 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3556 commented-out version of gh_eval_str()
3558 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3560 * socket.c (scm_bind): free soka after use.
3562 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3564 * stime.c (tzvar): new variable.
3565 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3566 avoid memory leaks when allocating.
3568 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3570 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3573 * gc.c, tags.h: Doc fixes.
3575 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3577 * eval.c (macro-eval!): Removed. This function was a design bug.
3578 It allowed memoized code to leak out to the scheme level. Most
3579 things that you could do with `macro-eval!' can be done with
3582 1997-12-20 Tim Pierce <twp@skepsis.com>
3584 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3585 scm_fgets now depends on ftell(3) to know how many bytes were
3588 1997-12-15 Tim Pierce <twp@skepsis.com>
3590 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3591 dealing with strings.
3593 1997-12-13 Tim Pierce <twp@skepsis.com>
3595 Make %read-line more suitable for implementing read-line efficiently.
3596 * ioext.c (scm_read_line): Strip the terminating newline from a
3597 string, and return a cons of the string and its terminator.
3599 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3600 of the string that is read is stored in this memory location.
3601 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3602 * genio.c, genio.h (scm_do_read_line): Update caller.
3603 * ports.h (scm_ptobfuns): Update typedef.
3604 * fports.c (scm_fptob, scm_pipob): Update struct.
3606 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3608 * filesys.c (set_element): Return file descriptor.
3609 (fill_select_type): Return the highest file descriptor.
3610 (scm_select): Tell select about the highest file descriptor. On
3611 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3612 Therefore the extra overhead for calculating the maximum fd seems
3613 to be more than compensated. Is this correct? In any case,
3614 scm_internal_select will be much faster with this info.
3615 (scm_select, fill_select_type, set_element): Don't accept any kind
3616 of object in the file descriptor list or vector.
3618 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3620 * iselect.c (finalize_fd_sets): Bugfix.
3622 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3624 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3625 when using scm_internal_select (since we might switch to another
3628 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3630 * simpos.c (scm_system): always define: use sysmissing if not
3631 available. Check for HAVE_SYSTEM instead of _Windows (does
3632 Windows lack system or does it have an unusable one?).
3633 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3634 Let the argument be optional: if not supplied, call system(NULL).
3636 * ports.c (scm_close_port): relax the type check from OPPORTP to
3637 PORTP; closing a closed port is allowed.
3639 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3641 * fports.c (scm_fgets): Return if the last char in a chunk is
3642 newline. When fgets returns a string whose length is `size-1', it
3643 is ambiguous whether a whole line was retrieved, so we must check
3644 explicitly whether a line terminator is present.
3646 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3648 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3649 before taking the CDR. (Thanks to Harald Meland.)
3651 * filesys.c (scm_stat): Slightly optimized.
3653 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3655 * ports.c (scm_close_port): Make sure the port is open before
3658 * guile-snarf.in: Pass args through to gcc in a way that preserves
3659 whitespace boundaries. (Thanks to Greg Badros.)
3661 1997-12-02 Tim Pierce <twp@skepsis.com>
3663 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3664 statement. (Thanks to Doug Evans for pointing this out.)
3666 1997-12-01 Tim Pierce <twp@skepsis.com>
3668 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3670 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3672 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3673 errno macro expansion of this field name. (errno is a C
3674 preprocessor macro on some systems.)
3676 1997-11-29 Tim Pierce <twp@skepsis.com>
3678 * iselect.c: Doc fix.
3680 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3682 * init.c (scm_start_stack): Removed initialization of
3683 scm_the_last_stack_var.
3685 * backtrace.h: Declare scm_the_last_stack_var.
3687 * backtrace.c: Define scm_the_last_stack_var.
3689 * root.c (mark_root): Don't mark the_last_stack_var.
3691 * root.h (scm_root_state): Removed the_last_stack_var.
3693 * throw.c: Added #include "fluids.h"
3694 (ss_handler): `the-last-stack' is now a fluid.
3696 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3697 --> the_last_stack_fluid.
3699 * backtrace.c: Added #include "fluids.h"
3700 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3701 (scm_backtrace): `the-last-stack' is now a fluid.
3703 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3704 after scm_init_fluids.
3706 1997-11-28 Tim Pierce <twp@skepsis.com>
3708 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3710 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3711 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3713 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3715 * iselect.c (coop_next_runnable_thread,
3716 coop_wait_for_runnable_thread): Disable interrupts so that no
3717 async is executed before a potential error_revive.
3718 (scm_internal_select): Disable interrupts during the parts of the
3719 code which manipulate the sleep queue and the file descriptors.
3721 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3723 * Makefile.am: Added iselect.c and iselect.h.
3725 * coop.c (coop_qinit): Initialize fields used by
3726 scm_internal_select.
3727 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3728 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3729 replacement in iselect.c.
3730 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3731 coop_join): If GUILE_ISELECT enabled, use
3732 coop_wait_for_runnable_thread instead of
3733 coop_next_runnable_thread.
3734 (usleep, sleep): New replacements for system functions if
3735 GUILE_ISELECT is enabled.
3737 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3739 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3741 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3742 iselect.h. Implement Scheme level `select' using
3743 scm_internal_select. (See NEWS.)
3745 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3747 * init.c: Call scm_init_iselect.
3749 * iselect.h, iselect.c: New files. Implements
3750 scm_internal_select. (See NEWS.)
3752 1997-11-27 Tim Pierce <twp@skepsis.com>
3754 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3755 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3756 and scm_must_free, since ultimately the string returned will be copied
3757 by scm_makfrom0str anyway. Also, read any characters that may have
3758 been pushed onto the port with scm_ungetc.
3759 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3760 * ioext.c (scm_read_line): Free string after Guilifying it.
3761 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
3763 1997-11-26 Anthony Green <green@hoser.cygnus.com>
3765 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
3767 * gh.h: Safely wrap prototypes for c++ usage.
3769 1997-11-25 Mark Galassi <rosalia@cygnus.com>
3771 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3772 gh_repl (argc, argv).
3774 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3776 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3777 and to invoke scm_shell().
3778 (gh_launch_pad): took out the loading of boot-9.scm from here,
3779 since it is probably best to let the user control that. In fact,
3780 gh_repl() now invokes scm_shell() which does that.
3782 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3784 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3787 1997-11-22 Tim Pierce <twp@twp.tezcat.com>

3790 yesterday's underscore patch. (Thanks to Marius Vollmer for
3793 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
3795 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
3796 DLSYM_ADDS_USCORE is not defined.
3798 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
3800 * gh_data.c (gh_uniform_vector_length):
3801 (gh_uniform_vector_ref): started implementing the uniform types in
3804 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
3806 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3807 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3809 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3811 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
3812 configure.in was changed).
3814 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
3816 * Makefile.am (modinclude_HEADERS): Include readline.h here.
3817 * Makefile.in: Regenerated.
3819 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
3821 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
3822 OPORT is an `open' port, not an output port.
3824 * filesys.c (scm_close, set_element, get_element, scm_chown,
3825 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
3826 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
3827 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
3828 scm_close_port, scm_port_line, scm_set_port_line_x,
3829 scm_port_column, scm_set_port_column_x, scm_port_filename,
3830 scm_set_port_filename_x, scm_port_mode,
3831 scm_close_all_ports_except, scm_set_current_output_port,
3832 scm_set_current_error_port): Likewise
3833 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
3834 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
3836 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
3837 * backtrace.c (display_backtrace_body): Likewise
3838 * fports (scm_setvbuf): Likewise
3839 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
3840 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
3841 scm_getpeername, scm_send, scm_sendto): Likewise
3842 * unif.c (scm_uniform_array_write): Likewise

3846 Minor problems with substring-related tag changes.
3847 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
3848 exactly what we want to leave in to detect substrings.
3849 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
3850 * tags.h: Fix diagrams and comments describing the S tag bit;
3851 remove vestigial remarks about the D tag bit.
3852 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
3853 * strings.c: Formatting tweaks.
3855 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
3856 variable first; then SCHEME_LOAD_PATH, with a warning message.
3857 (scm_parse_path): New function.
3858 * script.c: Doc fixes.
3860 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
3862 Readline support, from Daniel Risacher.
3863 * readline.c, readline.h: New files.
3864 * init.c: #include "readline.h".
3865 (scm_boot_guile_1): Call scm_init_readline, if we have it.
3866 * Makefile.am (libguile_la_SOURCES): Include readline.c.
3867 * Makefile.in: Regenerated.
3868 * scmconfig.h.in: Regenerated, after change to ../configure.
3870 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3872 * gh.h: gh_vector_set -> gh_vector_set_x
3874 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3876 * gh_data.c (gh_vector_set_x): changed name to make it consistent
3877 with the ! -> _x mapping when going from Scheme to C.
3879 1997-10-19 Mark Galassi <rosalia@cygnus.com>
3881 * gh.h (gh_reverse):
3889 (gh_assoc): added these gh_ functions implemented as macros.

3892 (gh_string_equal_p): added these two missing predicates.
3894 * gh_list.c (gh_append):
3899 (gh_set_cdr_x): added these routines as I go through and try to
3900 complete the picture R4RS functions that should be mirrored in the
3903 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3905 * tags.h (scm_tc7_substring): Changed the comment and code to
3906 conform with the changes below. Folks! We have suddenly two new
3907 free tc7 codes!!! Jummy, jummy!
3909 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
3911 * Makefile.in: Rebuilt.
3912 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,

3937 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
3938 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
3940 Don't include "mbstrings.h".
3941 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
3942 (SCM_SYMBOL_SLOTS): Define as 4.
3943 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.

3964 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
3965 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
3967 1997-10-12 Mark Galassi <rosalia@cygnus.com>
3969 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
3971 * gh_test_c.c (c_vector_test): some improvements on the vector
3974 * gh.h (gh_vector): this used to exist but do the wrong thing.
3975 Now it (almost) does the right thing, though it takes a list
3976 instead of the individual arguments. I need to see how it could
3978 (gh_list_to_vector): added this function as a macro. Corresponds
3979 to Scheme's (list->vector ...).
3980 (gh_vector_to_list): added this function as a macro. Corresponds
3981 to Scheme's (vector->list ...).
3983 * gh_data.c (gh_vector_ref): renamed from gh_vref to

3985 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
3986 resembles the Scheme routines more.
3987 (gh_make_vector): this used to be (stupidly) called gh_vector().
3988 This is the right name, since it does the same thing as the Scheme
3989 (make-vector ...) procedure.
3991 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
3993 * ports.h: #include "libguile/print.h"

3996 Some indentation fixes.
3998 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
3999 longer a user field; New field: class_flags.
4001 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
4003 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>

4006 gh_int2scmb(), which is now tagged as obsolete.
4008 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
4010 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
4011 macros should by convention not test for NIMPness.)
4012 (SCM_COERCE_OPORT): Adjust indentation.

4022 scm_struct_i_vtable_offset --> scm_vtable_offset_user
4024 * struct.c (scm_print_struct): Use new printer slot; Default
4025 printing: Also output hex code of vtable so that type identity
4026 will be indicated as well.
4027 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
4028 Removed struct_printer_var; Removed struct-vtable-offset;
4029 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
4030 vtable-offset-user): New constants.
4032 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
4033 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
4034 If this slot contains a procedure, use that to print structures of
4035 the type represented by this vtable.
4037 * print.c (scm_iprin1): Don't print arguments of macro
4038 transformers. (They are always: exp env.); Bugfix: Unmemoize
4039 transformer source with correct environment.
4041 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
4043 Streamlining of call-with-dynamic-root:
4045 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
4046 there is now only one catch.
4047 (cwdr_outer_body): Removed.
4048 (cwdr_handler): New function.
4049 (scm_internal_cwdr): New function to perform the function of cwdr
4050 but take args that are more useful to C code. Also, the handler
4051 is now invoked *outside* of the new dynamic root, like the docs
4052 say. We no longer have to catch absolutely all errors, the caller
4053 is responsible for using a handler that does not throw, if he
4055 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4056 * root.h (scm_internal_cwdr): New prototype.
4058 Even more but risky streamlining:
4060 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4061 allocation of the jumpbuf of a root continuation. The changes
4062 below are controlled by it. They are now deactivated.
4063 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4064 the JMPBUF of the scm_rootcont to NULL before returning.
4066 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4067 when they are non-NULL.
4068 (scm_gc_mark): Likewise, mark only when non-NULL.
4070 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
4071 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
4073 * gc.c (scm_done_malloc): New function.
4074 gc.h (scm_done_malloc): New prototype.
4076 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
4077 (struct scm_print_state) [revealed]: New field.
4078 (scm_print_state_vtable): Make visible to the outside world for
4079 type checking purposes.
4080 (scm_valid_oport_value_p): New prototype.
4082 * print.c (scm_valid_oport_value_p): New function to check whether
4083 a certain value is acceptable as a port argument.
4084 (scm_print_state_vtable): New variable.
4085 (scm_free_print_state): Set `revealed' field to false.
4086 (scm_iprin1): Call user supplied closure printer with
4087 scm_printer_apply. Print in the traditional way when there isn't
4088 one or when it returns #f.
4089 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4090 Accept a port/print-state pair in addition to just a port.
4091 (scm_prin1): Don't return the print_state to the pool when it has
4093 (scm_printer_apply): Set `revealed' field of print_state to true.
4094 (scm_init_print): Set scm_print_state_vtable.
4095 (print_state_fluid, print_state_fluid_num): Removed.
4097 * throw.h (scm_handle_by_proc_catching_all): New prototype
4098 throw.c (scm_handle_by_proc_catching_all): New function
4100 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
4102 * Makefile.in: Regenerated with automake 1.2c.
4104 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
4106 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
4107 was looping endlessly.
4109 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
4111 * strports.c (scm_eval_string): Don't close the port.
4113 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
4114 former returns a nice normal integer. (Thanks to Daniel
4117 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
4119 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
4120 makefile variable as a build parameter called LIBS. The
4121 build-guile program will use this, for the time being.
4122 * Makefile.in: Regenerated.
4124 Thanks to Shiro Kawai:
4125 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
4126 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
4129 * Makefile.in: Regenerated with automake 1.2a.
4131 * script.c (scm_compile_shell_switches): If we hit the -c or --
4132 arguments, don't set the car of (command-line) to scm_usage_name,
4133 the prettified name of the guile executable; give it the full
4134 path, the way shells usually handle $0.
4136 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4138 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
4139 Scheme-level name `array-map' and renamed `serial-array-map' to
4140 `serial-array-map!'.
4142 * backtrace.c: Introduced exception handlers which now enclose
4143 `display-error' and `display-backtrace' so that error reporting
4144 won't get into infinite loops if an error occurs during displaying
4145 of the error. This can very easily happen with user supplied
4146 print call-back routines.
4148 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4150 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
4151 the names `serial-array-map' and `array-map' should be removed.)
4153 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
4155 * init.c (scm_boot_guile_1): Added scm_init_objects ().
4156 Added #include "objects.h"
4158 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
4159 Add #include "feature.h".
4161 * Makefile.am (libguile_la_SOURCES): Added objects.c.
4162 (modinclude_HEADERS): Added objects.h.
4164 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
4165 This test is needed at many places in the code and should be
4166 abstracted. (Motivated by the need of this test in libguiletk.)
4168 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
4169 (scm_eval_string), load.c (scm_primitive_load,
4170 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
4171 Use SCM_EOF_OBJECT_P.
4173 * eval.c (scm_init_eval): Add feature `delay'.
4175 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4177 * scmhob.h: Removed.
4179 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4181 * list.h (SCM_LISTn): New macros. Make list creation in C code
4182 prettier. The idea comes from STk.
4184 * sequences.h, sequences.c, append.h, append.c: Removed. These
4185 files implemented non-R4RS operations which would encourage
4186 non-portable programming style and less easy-to-read code.
4188 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
4191 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
4192 sequences.h, #include append.h.
4194 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
4197 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
4199 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
4201 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
4203 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4205 * eval.c: Added #include "objects.h"
4207 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
4210 * smob.c (scm_smob_prehistory): Create two objectsmobs with
4211 adjacent smob numbers.
4213 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4215 * procprop.h: Added declaration of scm_i_inner_name.
4217 * gsubr.c: New global symbol scm_i_inner_name.
4219 * debug.c (scm_procedure_name): Try procedure property
4220 `inner-name' if `name' fails.
4222 * print.c (scm_iprin1): Use scm_macro_name.
4224 * eval.c (scm_m_define): Give names to macros as well; Only the
4225 first top-level definition gives a procedure/macro a name.
4226 Otherwise confusing names can turn up in backtraces.
4227 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4228 `name'; Give names to macros as well.
4230 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4231 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4234 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4236 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4238 (prinmacro): Removed. The code has been moved/merged into print.c
4239 in order to decrease code redundancy. We want macros to print in
4240 a way equivalent to procedures, and it would be silly to duplicate
4241 the required code. (We don't want to maintain two places.)
4242 (macrosmob): Print field is now a NULL pointer.
4244 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4245 scm_macro_transformer): New prototypes.
4246 (scm_tc16_macro): Declared.
4248 * print.c (scm_iprin1): Added code for printing of macros. Macros
4249 are now printed in a way equivalent to procedures.
4251 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4253 * procs.h (scm_closure_p): Added declaration.
4255 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4257 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4258 Shouldn't pass "heap" as the subr name.
4260 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4262 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4263 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4264 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4265 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4266 SCM_BOOL_T. Any non-false value is true.
4268 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4270 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4271 scm_gensym): Added prototypes.
4273 * symbols.c (scm_gensym): New function. This will speed up
4274 certain types of applications (such as macro systems) which
4275 generate lots of symbols.
4277 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4279 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4281 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4283 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4284 specifier, since (2) or (2 . 3) would cause SEGV.
4285 (scm_transpose_array): more argument checking fixes.
4287 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4289 * Makefile.in: Regenerated.
4291 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4293 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4295 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4297 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4299 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4301 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4302 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4305 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4306 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4307 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
4308 scm_array_p, scm_array_rank, scm_array_dimensions,
4309 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
4310 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
4311 scm_array_prototype): Added case scm_tc7_wvect.
4313 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
4315 * errno.h: prototype for scm_strerror.
4316 * error.c (scm_strerror): new procedure.
4318 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4320 * list.c (scm_list_append_x): Allow non-pair as last argument.
4321 This is consistent with the R4RS append and is probably the
4322 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4324 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4326 * stime.h: prototype for scm_times.
4327 * stime.c (scm_times): new procedure.
4328 * ioext.c (scm_fseek): if the first argument is a file descriptor
4330 (scm_ftell): if the first argument is a file descriptor call lseek
4332 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
4333 * filesys.c (scm_chmod): if the first argument is a file descriptor,
4335 (scm_chown): if the first argument is a port or file descriptor,
4337 (scm_truncate_file): new procedure.
4338 Add DEFER/ALLOW INTS to a few other procedures.
4339 (scm_fsync): new procedure.
4340 (scm_open_fdes): new procedure.
4341 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
4343 (scm_fcntl): the first argument can now be a file descriptor. The
4344 third argument is now optional.
4346 * posix.c (scm_execl, scm_execlp): make the filename argument
4347 compulsory, since omitting it causes SEGV.
4348 (scm_sync): return unspecified instead of #f.
4349 (scm_execle): new procedure.
4350 (environ_list_to_c): new procedure.
4351 (scm_environ): use environ_list_to_c. disable interrupts.
4352 (scm_convert_exec_args): take pos and subr arguments and
4353 improve error checking.
4355 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4357 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4358 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4359 argument to SCM_ASSERT. Furthermore, the name of the function
4360 should be passed as first argument when signalling
4361 SCM_WNA. (Thanks to Thomas Morgan)
4363 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4364 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4365 dispatches on the number of actual args has a default case
4366 reporting an internal error. This is a vestige from a version
4367 that mallocated a SCM vector to hold the arguments. In the
4368 current version this check is too late: if it ever happens we will
4369 have already overstepped the bounds of the array.
4371 Also, the patch [...] adds a check for too many actual arguments."
4373 mdj: Removed check for "internal programming error".
4375 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4377 * gh_io.c (gh_write): New function.
4379 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
4380 throw.c (scm_internal_stack_catch): New sibling to the other catch
4381 functions. Code moved from gh_eval.c.
4382 throw.h: Added header.
4383 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
4384 scm_internal_stack_catch.
4386 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4388 * ioext.h: fix up prototypes.
4389 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
4390 Scheme name is now dup->fdes.
4391 (scm_dup_to_fdes): make the second argument optional and
4392 fold in the functionality of scm_primitive_dup.
4393 (scm_primitive_dup): deleted.
4395 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
4397 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
4398 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
4399 ultrix are defined. Use setvbuf instead of setbuf.
4400 (scm_setvbuf): new procedure.
4401 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
4402 (scm_setfileno): moved from ioext.c.
4403 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
4404 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.

4413 * print.c (scm_iprin1): Enter printed structures into the print
4414 state as nested data while they are printed.
4415 (print_state_fluid, print_state_fluid_num): New variables.
4416 (scm_init_print): Initialize them.
4417 (scm_iprin): If print_state_fluid carries a print_state, use that
4418 instead of creating a new one.
4419 (scm_printer_apply, apply_stub, struct apply_data): New
4420 definitions to help with calling printer functions written in
4422 * print.h (scm_printer_apply): New prototype.
4424 * struct.c (scm_print_struct): Use scm_printer_apply to call the
4425 user defined struct printer.

4433 Fri Jul 25 12:05:46 1997 Marius Vollmer <mvo@zagadka.ping.de>
4435 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
4436 SCM_ASSERT: arg comes before pos.
4438 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4440 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
4441 to a list of length zero correctly.
4443 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4445 Supply an `fgets' method for port objects to do fast line i/o.

4459 * ioext.h: removed scm_duplicate_port prototype.
4461 * ioext.c (scm_primitive_dup2): return the new file descriptor
4462 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
4464 (scm_fdopen): bug fix: don't try to make port unbuffered until its
4465 stream has been set.
4466 (scm_duplicate_port): deleted, there's now an implementation in
4468 (scm_primitive_dup2): do nothing if newfd == oldfd.
4470 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
4472 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
4475 * ioext.h: new prototypes.
4476 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
4478 * fluids.c (next_fluid_num): don't do
4479 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
4481 * ports.h: prototypes too.
4482 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
4484 * fports.h: prototype too.
4485 * fports.c (scm_evict_ports): moved from ioext.c.
4487 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>

4494 and ports (scsh compatible).
4496 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
4499 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
4501 * fluids.c, fluid.h: New files.
4502 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
4503 (modinclude_HEADERS): Added "fluids.h"
4505 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to
4506 scm_init_fluids to initialize the fluid machine.
4507 (scm_start_stack): Initialize the fluids of the first root with
4508 scm_make_initial_fluids.
4510 * root.h: Added "fluids" member to scm_root_state.
4511 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
4512 (scm_make_root): Call scm_copy_fluids to make fluid bindings
4513 unique for the new root when it has a parent.
4515 * smob.h: Include "libguile/print.h" to make scm_print_state
4518 * dynl.c (free_dynl_obj): New function to free the dynamic object
4519 data. (dynl_smob): Use it.
4520 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4521 the dynamic object data below the linking of the object to avoid
4522 memory leak when the linking code throws an error. Now the code
4523 leaks a whole dynamically linked library when must_malloc throws,
4524 but that should be much less likely.
4526 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4528 Changes to compile under gnu-win32, from Marcus Daniels:
4529 * stime.c (tzset): If tzset isn't provided, make it a NOP.
4530 (scm_localtime): Change SCM_EOF to SCM_EOL.
4531 (scm_mktime): Likewise.
4532 * socket.c: Don't include sys/un.h unless autoconf tells
4533 us Unix domain sockets are available.
4534 (scm_fill_sockaddr): Ignore Unix domain code.
4535 (scm_addr_vector): Likewise.
4536 (scm_init_addr_buffer): Likewise.
4537 (scm_socketpair): Don't include unless socketpair was
4538 found during autoconf.
4539 * simpos.c (SYSTNAME): Treat cygwin like Unix.
4540 * scmsigs.c (scm_pause): Don't include unless pause was found
4542 * posix.c (scm_getgroups): Don't include unless support function
4543 was found during autoconf (in this case, getgroups).
4544 (scm_setpwent): For setpwent.
4545 (scm_setegid): For setegid.
4546 * net_db.c (scm_inet_netof): Don't include unless support
4547 function was found during autoconf (in this case, inet_netof).
4548 (scm_lnaof): For inet_lnaof.
4549 (scm_inet_makeaddr): For inet_makeaddr.
4550 (scm_getnet): For getnetent, getnetbyname, getnetbyaddr.

4553 (scm_sethost): For sethostent, endhostent.
4554 (scm_setnet): For setnetent, endnetent.
4555 (scm_setproto): For setprotoent, endprotoent.
4556 (scm_setserv): For setservent, endservent.
4557 * scmconfig.h.in: Regenerated.
4559 Thu Jul 10 00:22:24 1997 Jim Blandy <jimb@floss.red-bean.com>
4561 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
4562 scm_misc_error, not SCM_EOF.
4564 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
4565 arguments for formatting the error message, not SCM_BOOL_F. I
4566 think this is left over from the (eq? '() #f) days.
4568 * read.c (recsexpr): Give this a dummy definition if
4569 DEBUG_EXTENSIONS isn't #defined.
4571 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
4573 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
4576 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>
4578 * root.c (cwdr_outer_body): Bugfix: Pass `c' instead of `&c' to
4581 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
4583 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
4584 alloca.lo will be included in @LIBLOBJS@. Something better than
4585 this should be possible.
4586 * Makefile.in: Regenerated.
4588 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4590 * simpos.h: prototype for scm_primitive_exit.
4591 * simpos.c (scm_primitive_exit): new procedure, terminates the
4592 process without unwinding the stack.
4594 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
4596 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
4597 argument and logior its components together, so the user doesn't
4598 have to do this explicitly. Also, if regexp/basic is supplied, then
4599 turn off REG_EXTENDED.
4600 (scm_init_regex_posix): New regexp/basic symbol.
4601 (REG_BASIC): #define this if it is not already present.
4603 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4605 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
4606 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
4607 (CLEANFILES): New target, clean versiondat.h, libpath.h.
4608 (DISTCLEANFILES): New target, clean *.x.
4609 * Makefile.in: Regenerated.
4611 Tue Jun 24 00:29:07 1997 Jim Blandy <jimb@floss.red-bean.com>
4613 * script.c (scm_compile_shell_switches): Add 1997 to copyright
4614 years in usage message.
4616 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
4617 * Makefile.in: Regenerated.
4619 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
4620 flag; I don't think we support it.
4621 (scm_make_regexp): Make sure the user doesn't pass the
4624 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
4626 (scm_init_regex_posix): Define constants for the REG_mumble flags;
4627 name them according to the SCSH convention: regexp/mumble.
4629 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
4631 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
4633 * Makefile.am (libpath.h): Include the values of all the standard
4634 Makefile directory variables. Print a message, but don't print
4636 (versiondat.h): Print a message, but don't print all the commands.
4637 * load.c: #include "alist.h".
4638 (init_build_info): New function.
4639 (scm_init_load): Call it.
4640 * Makefile.in: Regenerated.
4642 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
4644 * root.c: Establish a reliable catch-all handler for the new root.
4645 After all the Scheme handler function might signal an error too,
4646 and we don't want to lose that.
4647 (cwdr_inner_body): Renamed from cwdr_body.
4648 (cwdr_outer_body): New function, to establish the user's handler,
4649 and pass control to cwdr_inner_body.
4650 (cwdr): Establish the reliable catch-all handler here, and pass
4651 control to cwdr_outer_body.
4652 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
4653 the user's handler through to cwdr_outer_body.
4654 * throw.c (scm_handle_by_message): Move guts into....
4655 (handler_message): New static function.
4656 (scm_handle_by_message_noexit): New function.
4657 * throw.h (scm_handle_by_message_noexit): New prototype.
4659 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
4660 across this. Only works on GCC. Otherwise, we hope for the best.
4661 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4662 the feeling that real thread systems will not need this...
4664 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4666 Try to detect when people are using one version of libguile and a
4667 different version of ice-9. People have been skewing things and
4668 sending in bug reports.
4669 * Makefile.am (versiondat.h): New file to generate.
4670 * version.c: #include "versiondat.h", to get version info.
4671 (scm_libguile_config_stamp): New function.
4672 * script.c: #include "version.h".
4673 (scm_compile_switches): Call scm_version to get version number.
4674 * scmconfig.h.in, Makefile.in: Regenerated.
4675 * Makefile.in: Regenerated.
4677 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
4678 primitive definitions under their Scheme names.
4680 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4681 1:2. Helps avoid confusion between installed and uninstalled libs.
4683 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
4686 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
4687 backslash from definition; this should be used like: GDB_INTERFACE;
4689 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4691 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
4692 new port unbuffered until its stream has been set.
4694 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
4696 * ports.h: new prototype.
4697 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
4699 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
4701 Make things compile neatly under Sun's C compiler.
4702 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
4703 * extchrs.c (xmbtowc): Make the second arg a normal char, not
4704 unsigned, because that's what the ANSI function takes.
4705 * extchrs.h (xmbtowc): Corresponding change to prototype.
4706 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4708 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
4709 argument plain char *.
4710 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
4712 * tag.c (scm_tag): Remove unreachable statement.
4713 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4714 top of the word, it should be unsigned.
4716 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4717 is defined, to avoid warnings; it's only used in the
4718 conflict-checking code. Which might go away anyway.
4719 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4720 conditionals; put the label definition in an #if too, to stifle
4723 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4724 ChangeLog-threads in the distribution.
4725 * Makefile.in: Regenerated.
4727 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4729 * guile-snarf.in: Changed regexp to support CPPs that insert
4730 whitespace between lexical tokens (which munges the `%%%' snarf
4733 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4735 * load.c (scm_init_load_path): Append $(datadir)/guile to
4736 %load-path, so modules do not have to be installed in Guile's
4737 current version directory.
4739 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
4741 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
4742 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
4743 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
4744 call the sysdep functions with deferred ints.
4745 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
4746 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
4747 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
4750 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
4753 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
4755 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
4757 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
4759 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
4762 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
4764 * eval.c (scm_lookupcar1): New procedure to cope with a race
4765 condition during lookup (when using threads).
4766 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4767 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4770 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4772 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4773 supplied. (Change from Tim Pierce.)
4775 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4777 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4778 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4779 default and not `()'. `#f' is the canonical non-value in Scheme,
4782 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4784 * struct.c (struct_printer): New variable that holds a handle on
4785 the Scheme variable *struct-printer*. This variable can be set by
4786 Scheme code to override the printing of structures.
4787 (scm_print_struct): If struct_printer is set, call it. If it is
4788 not set, or returns #f, print the structure in the old fashion.
4789 Include "eval.h" for scm_apply.
4791 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4793 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4794 scm_struct_i_n_words to get the number of fields, not
4795 -scm_struct_n_extra_words.
4797 On the route to fancier struct printing:
4798 * struct.c (scm_print_struct): New function to print a structure.
4799 Include "genio.h" to support it. This function doesn't do
4800 anything interesting right now, but I think it should be here
4802 * struct.h: Include "print.h" and add prototype for
4804 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4805 print structures ourself.
4807 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4809 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
4810 before applying the handler in case it doesn't return.
4812 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
4814 * scmsigs.h, async.h: updated.
4816 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
4819 * posix.c (scm_uname): interpret only negative values as an error.
4820 Solaris normally returns a positive value.
4822 * script.c (scm_compile_shell_switches): if we are not going into
4823 an interactive repl, set scm_mask_ints to zero so that asyncs can
4826 * simpos.c (scm_system): don't ignore/unignore signals around
4829 * posix.c (scm_open_pipe): don't ignore/unignore signals around
4832 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
4833 done in boot-9.scm instead.
4835 * scmsigs.c, async.c: Major rewriting of signal handling code.
4836 (scm_sigaction): new procedure.
4837 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
4839 (scm_raise): return unspecified, throw error on failure.
4841 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4843 * regex-posix.c (scm_init_regex_posix): Register the "regex"
4844 feature, to help boot-9.scm decide whether to import the regex
4847 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
4849 * eval.c: Include scmconfig.h at the beginning of the file so that
4850 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
4853 * regex-posix.c: #include "_scm.h" before conditionally #including
4854 <regex.h>; the former defines HAVE_REGCOMP.
4856 * regex-posix.c: #include <regex.h> conditionally, so the file is
4857 CPP'able (for dependency scanning) even on systems that don't have
4860 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4862 Add new R4RS-compliant syntax for keywords.
4863 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
4864 regardless of the setting of the `keywords' read option.
4865 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
4866 can be re-read no matter what the setting of the `keywords' read
4869 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
4871 Add support for POSIX regular expressions.
4873 * regex-posix.c, regex-posix.h: New files. (Some code
4874 is taken liberally from rx/rgx.c in the old Guile dist.)
4876 * init.c: Include regex-posix.h.
4877 (scm_boot_guile_1): Call scm_init_regex_posix.
4879 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
4880 Add regex-posix.[ch] sources.
4881 * Makefile.in: Regenerated.
4883 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
4884 to do this automatically? It didn't for me, bleh.)
4886 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
4888 * fports.c (print_pipe_port): New function.
4889 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
4890 latter doesn't even take the right arguments.
4892 * Makefile.am: Increment shared lib revision number. I think
4893 sometimes the uninstalled Guile finds the installed shared lib;
4894 Gord says doing this might help. As things turned out, I can't
4895 say whether it does.
4896 * Makefile.in: Regenerated.
4898 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
4899 passing it as the closure argument to scm_boot_guile. (Bill
4902 * ports.c (print_void_port, putc_void_port, puts_void_port,
4903 write_void_port, flush_void_port, getc_void_port, close_void_port,
4904 noop0): Use ANSI prototypes instead of K&R declarations, so the
4905 initialization of void_port_ptob gets aggressively type-checked.
4906 Fix arguments of print_void_port and write_void_port. (Bill

4940 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
4942 * script.c (scm_find_executable): Use prototype-style definition
4943 here; apparently it's not quite right to have const in a prototype
4944 and then use a K&R declaration. I wonder if stuff like this will
4945 go away if we compile with -Wrequire-prototypes, or whatever that
4946 is... (Bernard URBAN)
4948 * scmhob.h: New text from Bernard URBAN.
4950 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4952 * script.c: Don't #define const on hpux. Configure takes care of
4953 this. (Thanks to Larry Schwimmer.)
4955 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
4956 decide whether to #include <unistd.h>, instead of listing a bunch
4957 of systems. Don't #include stdio twice. Removed dyked-out
4958 definition of scm_find_impl_file.
4960 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4962 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared

4970 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
4971 throw.c: Update copyright years; these files have been worked on
4972 significantly in 1997, but only had copyright years for 1996.
4973 Also, change name of copyright holder on some from Mikael
4974 Djurfeldt to Free Software Foundation; he has signed papers
4975 assigning the changes to the FSF.
4977 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
4978 reason not to give the user the option.
4980 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
4981 Return #f on end-of-file when scanning table (i.e. when called
4982 with no arguments). Try to catch errors, when we can.
4983 * posix.c (scm_getgrgid, scm_getpwuid): Same.
4985 * script.h (scm_shell_usage, scm_compile_shell_switches): New
4986 external declarations. These are useful.
4988 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
4990 * posix.c: don't include <sys/select.h> or define macros for
4991 select, since they were not used in this file.
4993 * filesys.c (scm_select): make the fifth parameter microseconds,
4994 not milliseconds. let the fourth parameter be either a real value
4995 or an integer or #f. The first, second and third arguments can
4996 now be vectors: the type of the corresponding return set will be
4998 (set_element, get_element): new static procedures.
5000 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
5002 * strports.c (scm_eval_string): New function.

5010 (scm_pipob): Use it in the initializer here.
5013 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
5014 Use a meaningful error message when signalling an error. For
5015 this, scm_gethost must check h_errno rather than errno.
5017 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
5019 * Makefile.in: Regenerated, using automake-1.1p.

5023 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
5024 not SCM_UNSPECIFIED.

5028 (scm_shell): call scm_exit_status and exit on the result of the
5031 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
5033 Ensure that shared substrings are handled properly when passed to
5034 a system call or other foreign function. Many thanks to Tim
5036 * symbols.h (SCM_COERCE_SUBSTR): new macro.
5037 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
5038 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
5039 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

5041 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
5042 (scm_display_error_message): use RO macros when strings may be RO.
5043 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
5044 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
5045 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
5046 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
5047 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
5048 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
5049 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
5050 scm_strftime), vports.c (scm_make_soft_port): use
5051 SCM_COERCE_SUBSTR to make sure shared substrings are

5056 * error.c (scm_error): Add newline to error message.
5058 * init.c (scm_init_standard_ports): Doc fix.
5060 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5062 * dynl-shl.c: Completely replaced with new code from Bernard
5065 * script.c (scm_ice_9_already_loaded): New variable.
5066 (scm_compile_shell_switches): Use it.
5068 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5070 * filesys.c (scm_input_waiting_p): add missing third argument to
5073 * stime.c (scm_localtime): copy the result of localtime before
5074 calling gmtime in case they share a buffer.
5075 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE

5082 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5084 * Makefile.am (check-local): New target, which causes 'make check'
5085 to run gh_test_c and gh_test_repl, with some trivial input.
5086 * Makefile.in: Rgnrtd.
5088 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5090 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5093 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
5095 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
5096 sure how this was supposed to work.
5097 (scm_async_click): don't send SCM_TICK_SIGNAL.
5098 (scm_init_async): don't initialize %tick-thunk.
5100 * the following change doesn't affect the Scheme interface:
5101 gc-thunk is called at the end of garbage collection. however it's
5102 no longer implemented by pretending it's a signal.
5104 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
5105 system async corresponding to scm_gc_thunk.
5106 * async.h: declare scm_gc_async.
5107 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
5108 gc-thunk directly, instead of going through a signal handler.
5109 (scm_gc_async): new variable, points to the GC system-async.
5110 (scm_init_async): save the GC async as scm_gc_async instead
5111 of using system_signal_asyncs.
5112 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
5114 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
5116 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
5117 Don't screw up if we're interrupted.
5118 * Makefile.in: Regeneradet.
5120 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
5122 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
5124 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
5125 we're not using AM_INIT_GUILE_MODULE any more.
5126 * Makefile.in: Reneregated.
5128 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>

5131 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
5132 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
5134 Get 'make dist' to work again.
5135 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
5136 * Makefile.in: Regenerated, like a surry without a fringe on top.
5138 Changes for reduced Guile distribution: one configure script,
5140 * configure.in, configure: Removed.
5141 * acconfig.h, acinclude.m4: Moved to parent directory, where the
5142 real configure script lives.
5143 * Makefile.in, scmconfig.h.in: Regenerated.
5145 * init.c: #include "script.h", to get prototype for script.c's
5148 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
5150 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
5151 scm_must_malloc, not raw malloc.
5153 * script.c (scm_compile_shell_switches): Dyke out debugging output
5156 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5158 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
5160 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
5161 system has them. Hope this is safe. Previously
5162 sys/timeb.h was included if HAVE_FTIME was defined or if
5163 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
5164 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
5166 * ioext.c (scm_setfileno): add missing third argument to
5167 scm_misc_error call.
5169 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
5171 * eq.c (scm_equal_p): Correctly compare strings of different
5172 varieties. (Thanks to Tim Pierce.)
5174 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
5176 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
5177 #! block comment must occur on a line all by itself.
5179 Move most of the guts of shell command processing into libguile,
5180 so guile.c can be very small (and eventuallly auto-generated. (I
5181 mean, generated mechanically, not self-generated. Hmm.))
5182 * guile.c, script.c, script.h: New source files.
5183 * init.c (scm_boot_guile_1): Call scm_init_script.
5184 * libguile.h: #include "script.h".
5185 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
5186 targets, for new executable.
5187 (libguile_la_SOURCES): Mention script.c.
5188 (modinclude_HEADERS): Add script.h.
5189 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
5190 not dynamic linking is enabled. This is because we're generating
5191 executables now. Move CY_AC_WITH_THREADS call after those, so the
5192 values of cy_cv_threads_libs captures the libs chosen above.
5193 * Makefile.in, configure, aclocal.m4: Regenerated.
5195 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
5196 We don't maintain this interface any more, and it just confuses
5199 * alloca.c: #include <scmconfig.h>, not <config.h>.
5200 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
5201 it'll get included in disties.
5203 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5205 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
5206 be distributed, because they confuse people.
5207 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
5209 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
5211 * configure.in: check for presence of gethostent (not present on
5212 OpenBSD by default).
5213 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
5214 * configure, scmconfig.h.in: Regenerated.
5216 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5218 * backtrace.c (scm_backtrace): Split message string across
5219 newlines properly. GCC is more tolerant of this than other
5222 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
5224 Merge threads directory into libguile.
5225 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5226 threads.h: New source files.

5228 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
5230 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5231 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5232 coop-threads.c.cygnus, coop-threads.h.cygnus.
5233 * configure.in: If we're using threads, include threads.o in
5235 * _scm.h, libguile.h: threads.h lives in this directory now.
5236 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5237 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5238 currently used, but brought along for information's sake.
5239 * ChangeLog-threads: log from old 'threads' directory.
5240 * Makefile.in, configure: Rebuilt.
5242 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5244 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5247 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5249 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5251 Merge GH interface library into libguile.
5252 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
5253 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5254 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5255 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5257 (EXTRA_libguile_la_SOURCES): ... here.
5258 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5259 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5260 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5261 New variables, describing how to build the gh test programs.
5262 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5263 build the test programs, and we probably should have been linking
5264 libguile.la against them all along, to support AIX shared libs.
5265 Add cflags for threads to CFLAGS; add libs for threads to new
5266 variable THREAD_LIBS, used in Makefile.am.
5267 * ChangeLog-gh: log from old `gh' subdirectory.
5268 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5270 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5272 * acconfig.h: Undo change of Apr 9; including the definition of
5273 PACKAGE in the guile headers conflicts with applications' own
5275 * scmconfig.h.in: Regenerated.
5277 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

5284 when PROC is receiving no arguments.
5286 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5288 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5289 have S_IFSOCK. This is the case under Ultrix.
5291 * posix.c (scm_status_exit_val, scm_status_exit_val,
5292 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5293 Ultrix versions of WIFSTOPPED, etc., which assume that their
5294 arguments are lvalues (hmm).
5296 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5298 * eval.c: Doc fixes.
5300 * throw.c: Doc fixes; rearranged.
5302 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.

5306 * acconfig.h: Added entry for PACKAGE.
5307 * scmconfig.h.in: Regenerated.

5310 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5311 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the

5315 * Makefile.in: Rebuild.
5317 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5319 * stime.c (scm_mktime): take an optional zone argument.
5320 (scm_localtime): check putenv return value.
5321 (scm_strftime, scm_strptime): moved from posix.c. move #include
5323 stime.h, posix.h: update prototypes.
5324 (bdtime2c, setzone, restorezone): new static procedures.
5325 (scm_mktime, scm_strftime): use them.
5326 (scm_strftime): don't call mktime before strftime. Use
5327 filltime for return value.
5328 (filltime): convert NULL zname to #f.
5329 (scm_strptime): return a count of characters consumed, not
5330 the remaining string.
5332 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5334 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
5335 (scm_mktime): likewise.
5337 Uncomment localtime and mktime.
5339 * configure.in: add AC_STRUCT_TIMEZONE.
5341 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5343 * stime.c (scm_init_stime): don't define ticks/sec.
5344 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5345 return value problem and is still portable.)
5347 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5349 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5350 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5351 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5352 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5353 cpp_err_symbols.c): Corresponding changes.
5354 * Makefile.in: Regenerated.
5356 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>

5361 * putenv.c: new file, from sh-utils 1.12.
5363 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5364 since allocation isn't for Scheme objects.
5365 (scm_putenv): copy strings before placing in the environment.
5367 * stime.c (scm_current_time): throw an error if time returns -1,
5368 instead of returning #f.
5369 (scm_get_internal_real_time, scm_get_internal_real_time): use
5370 scm_long2num for return value instead of SCM_MAKINUM.
5372 * stime.h: prototypes updated.
5374 * stime.c (scm_time_in_msec): apparently unused, deleted.
5376 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5378 * configure.in: check for gettimeofday.
5380 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5381 which may be more usefully portable than a gettimeofday interface.
5383 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5385 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not

5391 * stime.c (filltime): recovered static procedure.
5392 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5395 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5396 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5398 * posix.c (scm_mknod): split the mode argument into type and perms
5399 arguments, like the extra fields returned by stat.
5401 * fports.c (scm_pipob): set the close, free and print procedures.
5402 (scm_close_pipe): new procedure.
5404 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5405 define them in boot-9.scm
5407 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5409 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5410 wan't defined. Don't include fd.h.
5412 * Previously fd.h was regenerated whenever configure was run,
5413 forcing a couple of files to be recompiled.
5415 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5416 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5417 Check for _fileno as well as _file.
5419 * ioext.c: don't fd.h.
5420 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5423 * Change the stratigy for getting information about errno
5424 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5425 generating lists of symbols during the build process, which will
5426 not always work, include comprehensive lists in the distribution.
5427 To help keep the lists up to date, the "check_signals" and
5428 "check_errnos" make targets can be used.
5430 * configure.in: don't check for a command to extract errno codes.
5431 * Makefile.am: update file lists, remove errnos.list and errnos.c
5432 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5433 check_errnos targets.
5434 (CLEANFILES): remove errnos.c and errnos.list, add
5435 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5436 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5437 * errnos.default: deleted.
5438 * cpp_signal.c: new file.
5439 * cpp_errno.c: renamed from errnos_get.c.
5440 * cpp_err_symbols, cpp_sig_symbols: new files.
5441 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5442 * error.c (scm_init_error): #include cpp_err_symbols instead of
5444 * posix.c (scm_init_posix): don't intern signal symbols. #include
5447 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5449 * strop.c (scm_i_index): allow the lower bound to be equal to the
5450 length of the string, so a null string doesn't always give an error.
5452 * posix.h: new prototypes.
5453 * posix.c (scm_status_exit_val, scm_status_term_sig,
5454 scm_status_stop_sig): new functions, as in scsh. They break down
5455 process status values as returned by waitpid.
5457 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5459 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5460 configure doesn't know about it.
5462 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5464 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5466 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5467 which defines C variables with global linkage.
5469 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5471 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5474 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5476 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5477 has time to check why this doesn't work well with continuations.
5479 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5481 * Fix shell syntax error; some shells won't tolerate
5482 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5484 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5486 * posix.c (scm_uname): throw an error if uname fails instead
5489 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5491 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
5494 * async.c (scm_ints_disabled): definition moved from error.c.
5496 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5498 * acconfig.h: Removed PACKAGE.
5500 * scmconfig.h.in: Regenerated.
5502 * snarf.h: g++ says it's non-portable not to specify the first
5503 argument in a varargs declaration. I introduced the first
5504 argument by using preprocessor conditionals.
5506 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5508 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5509 (scm_freopen): use RO string macros for filename and modes.
5510 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
5512 * posix.c (scm_getgrgid): simplify conversion of name to C string.
5513 (scm_mknod): use RO string macros for path.
5515 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
5516 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5518 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5519 use SCM_ROSTRINGP and SCM_ROCHARS.
5521 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5523 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5526 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5527 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5528 support for byte vectors.
5530 * print.c (scm_iprin1): Limit number of vector elements printed
5531 according to pstate->length.
5533 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5535 * backtrace.c (scm_display_error_message): don't segv if message
5538 * error.h: prototype for scm_error_scm.
5540 * error.c (scm_error_scm): new procedure, reimplements scm-error
5541 in C and uses scm_error.
5543 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5545 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5546 pointer to the Scheme variable read-hash-procedures and intern it
5547 in scm_init_read. Modify scm_read_hash_extend and
5548 scm_get_hash_procedure to use the pointer.
5550 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5552 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5553 (SCM_KEYWORD_STYLE): defined.
5555 * read.c (scm_read_opts): add a keywords option. This isn't a
5556 boolean option, in case someone wants to add support for DSSSL
5558 Setup scm_keyword_prefix symbol.
5559 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5561 I've left keyword support disabled by default, since it doesn't
5562 seem to break the module system and it gives R4RS standard behaviour.
5563 It can be reactivated with (read-set! keywords 'prefix).
5565 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5567 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5568 before constructing arbiter.
5570 * eval.c (scm_m_define): Bugfix: Check that the object is a
5571 closure before setting the procedure property!
5573 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5575 * ports.c: Removed `ungetc-char-ready?'.
5577 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5579 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5580 (idea from Mikael: make it a pair so scm_permanent object only
5582 (scm_read_hash_extend): don't call scm_permanent_object.
5583 (ideas from Mikael): if chr is already in the list, replace its
5584 procedure instead of appending it again. If proc is #f, remove
5586 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5588 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5590 * gdbint.c (gdb_read): update scm_lreadr usage.
5592 * load.h: update prototypes.
5594 * load.c (scm_primitive_load, scm_read_and_eval_x,
5595 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
5597 * read.h: add prototype for scm_read_hash_extend. Change args for
5600 * read.c (scm_read_hash_procedures): new variable.
5601 (scm_read_hash_extend): new procedure.
5602 (scm_get_hash_procedure): new procedure.
5603 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5604 for extended # processing.
5605 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5606 scm_read_token): remove case_i, sharp arguments. Change callers.
5608 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5610 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5611 (SCM_CASE_INSENSITIVE_P): define.
5613 * read.c: add case-insensitive option to scm_read_opts.
5614 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5615 to determine whether to convert symbol case.
5616 (default_case_i): definition removed.
5617 * read.c (scm_read_token): if case_i, downcase ic before doing
5620 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5622 * configure.in: Added configuration option `guile-debug'.
5623 Configure with --enable-guile-debug if you want a bunch of extra
5624 functions used for debugging when developing Guile.
5626 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5628 * procs.c (make-cclo): New undocumented debugging procedure: Make
5629 compiled closure with internal procedure PROC and length LENGTH.
5630 Only compiled if GUILE_DEBUG is defined.
5632 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5634 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5636 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5638 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5639 with 3 or more args internally to the evaluator.
5641 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5643 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5644 with 3 or more args internally to the evaluator. This is mainly
5645 because we don't want to pass entry and exit points of the
5646 debug support twice, but it also seems to increase the speed of
5647 the evaluator for such calls (e. g. (+ 1 2 3)).
5649 * backtrace.c (scm_display_application): New procedure:
5650 display-application; Set fancy printing parameters individually
5651 for different types of display (backtrace, error, application).
5652 (These should of course be customizable!)
5654 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5655 clear the CHECK-flags.
5657 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5659 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5661 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5663 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5664 from pairs with a GLOC in the car.
5666 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5667 otherwise `symbol-hash' will behave badly.
5668 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5669 we get segmentation fault!
5671 * symbols.c: Added #include "weaks.h". New functions:
5672 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5673 moved to an extraneous library when we split libguile.)
5675 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5677 * filesys.c (scm_stat): stat now takes fport arguments too as
5678 documented in the manual.
5680 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5682 * debug.c (scm_single_step): Bugfix: Call continuation with
5683 scm_call_continuation instead of throwing to it.
5685 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5687 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5688 argument wasn't declared to be optional.
5690 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5692 * stime.c (scm_init_stime): Add feature "current-time".
5694 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5696 * throw.h: prototype for scm_exit_status.
5697 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5698 args to derive an exit status. Allows (quit) to work from a
5700 (scm_exit_status): new function.
5703 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5705 * eval.c (scm_deval): Removed some old code.
5706 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5708 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5711 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5714 * procs.c: Introduce the existent C function scm_thunk_p at the
5715 Scheme level as well.
5717 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5719 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5720 used from C to easily lookup the value of a symbol in the current
5723 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5725 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5726 scm_init_unif in this file. This will also fix a previous problem
5729 * configure.in: Added AM_MAINTAINER_MODE
5731 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5733 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5736 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5738 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5739 source files that are not always included in libguile but should
5740 have their dependencies calculated by automake. This variable is
5741 recognized by automake, no further magic is needed.
5742 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5743 to deal exclusively with *.lo files, as it seems. The *.o files
5744 are built automatically when the corresponding *.lo file gets
5747 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5749 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5752 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5754 * unif.c (scm_array_set_x): minor change to argument error checking.
5756 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5758 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5759 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5760 They should only be included in the library at configure.in's
5762 (libguile_la_LDADD): Include the appropriate .lo files here.
5763 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5764 so we know when to build them (and their .lo bretheren).
5765 * configure.in (LIBLOBJS): New substituted variable. We let
5766 configure decide which .o files to include in LIBOBJS, and then
5767 put the corresponding list of .lo files in LIBLOBJS. The latter
5768 is what we pass to libtool.
5769 * Makefile.in, configure: regenerated.
5771 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5773 * symbols.c (scm_sysintern0): New function. Contains the core of
5774 old scm_sysintern but doesn't take a second value argument.
5775 (scm_sysintern): Now uses scm_sysintern0.
5776 (scm_sysintern_no_module_lookup): Renamed to
5777 scm_sysintern0_no_module_lookup and doesn't take a second value
5778 argument any longer.
5780 * symbols.h (scm_sysintern0: Added declaration.
5782 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5783 scm_sysintern when interning option keys. Otherwise we risk
5784 destroying the values of already interned variables.
5786 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5787 scheme-level boolean (use SCM_NFALSEP).
5789 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5791 (scm_backtrace): New function. (C version of old function from
5792 boot-9.scm) Motivation: Make it possible to display backtraces
5793 without depending on boot-9.scm. (I'm uncertain if this
5794 motivation is good enough...)
5796 * root.h (scm_root_state): Add member the_last_stack_var.
5797 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5799 * root.c (mark_root): Mark scm_the_last_stack_var.
5801 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5804 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5806 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5807 1. mark_lazy_catch didn't mark the smob.
5808 2. Both functions above have standard variants:
5809 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5810 free_lazy_catch --> scm_free0.
5812 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5814 * throw.c (scm_internal_lazy_catch): New function.
5815 (scm_lazy_catch): Rewritten to use it.
5816 (scm_ithrow): Handle the new lazy catch representation.
5817 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
5818 that doesn't have a jmpbuf is a lazy catch clause.
5819 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
5820 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
5821 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
5823 (scm_init_throw): Register the new lazy-catch smob type.
5824 * throw.h (scm_internal_lazy_catch): decl for new function.
5826 * throw.c (scm_internal_catch): Doc fixes.
5828 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
5829 configure.in. Including this might cause problems if applications
5830 that link against libguile include their own copies of alloca, but
5831 if they're using autoconf, they should be adding libguile to LIBS
5832 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
5833 the copy in libguile, and things will be okay. (I think.)
5835 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5837 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
5839 strop.h: move prototypes too.
5841 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5843 * posix.c (scm_init_posix): don't intern EINTR since it's now done
5846 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
5847 etc. I deleted them from filesys.c long ago, but didn't
5848 notice they were here too (although ineffective since
5849 sys/stat.h wasn't included).
5851 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
5853 * eval.c: Don't define alloca in GCC case. gcc will automatically
5854 use __builtin_alloca if appropriate.
5856 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5858 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
5859 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
5860 that values of automatic variables are preserved. See comments
5861 for safe_setjmp for details.
5863 Change from Thomas Morgan:
5864 * variable.c: Include eq.h.
5865 (var_equal): New function.
5866 (variable_smob): Use var_equal as the discriminator for variables.
5868 * throw.c (s_throw): Remove extraneous declaration.
5870 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
5871 * eval.c: Add necessary CPP cruft to support that.
5872 * configure, Makefile.in, scmconfig.h.in: regenerated.
5874 Change from Thomas Morgan:
5875 * procprop.c (scm_procedure_properties): Convert the Scheme
5876 boolean returned by scm_procedure_p into a C boolean before using
5877 it as a condition for SCM_ASSERT.
5878 (scm_procedure_property): Likewise.
5880 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
5881 indications of Unixness.
5884 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5886 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
5888 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5890 * read.c (scm_lreadr): use scm_misc_error to improve one of the
5891 "unknown # object" error messages.
5893 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
5894 (scm_i_index) and declare it static. Add a 'direction' argument
5895 to indicate what way the search should go.
5896 (scm_i_index): throw out-of-range error instead of wrong-type-arg
5898 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
5899 strop.h: remove scm_i_index, scm_i_rindex prototypes.
5901 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5903 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
5905 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
5906 to avoid clash with various scsh forks.
5908 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
5910 The following two changes (ramap.c, throw.c) are motivated by the
5911 apparent unportability of forward declarations of static arrays of
5912 the form `static foo bar[];'.
5914 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
5915 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
5917 * throw.c (scm_throw): Moved above scm_ithrow.
5919 * options.h: Removed the extern declarations of scm_yes_sym and
5920 scm_no_sym since these are static.
5922 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5924 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
5926 * Makefile.am: remove AWK=@AWK@.
5927 Add a rule for generating errnos.list.
5928 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
5930 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
5931 don't extract errnos, just set a variable (avoids the
5932 need to recompile error.c just because configure is run.)
5934 * unif.h: update prototypes.
5935 * unif.c (scm_uniform_array_read,write): change the offset and
5936 length arguments to start and end, for consistency.
5938 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
5940 * ioext.h: update prototypes.
5941 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
5942 scm_read_line_x, it's a more general procedure using an
5943 interface from scsh. read-line and read-line! are now defined
5945 Note that the new read-line trims the terminator
5946 by default, previously it was appended to the returned string. An
5947 optional argument specifies how to process the terminator (scsh
5948 compatible). For the old behaviour: (read-line port 'concat).
5949 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
5950 returns a pair, but is converted to multiple values if the scsh
5953 socket.h: update prototypes.
5954 * socket.c (scm_recvfrom): for consistency with other procedures,
5955 take start and end as separate optional arguments.
5956 (scm_recv, scm_recvfrom): don't allow the second argument
5957 to be a size, only a buffer. Change the scheme names to
5958 recv! and recvfrom!. Don't return the buffer.
5960 * ioext.h, posix.h: move prototypes too.
5961 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
5962 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
5963 "read.h" and "unif.h".
5964 * ioext.c: include "chars.h"
5966 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
5968 * dynl.c: The dynamic linking and module registration functions
5969 are now defined even when dynamic linking is not available for the
5970 host system. Some of their functionality can be done without
5971 dynamic linking; when it's really needed, they throw errors.
5973 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
5975 * configure.in: Only define DYNAMIC_LINKING when one of the system
5976 dependent functions is detected.
5977 * dynl.c (scm_dynamic_func): New function to get the address of a
5978 function in a dynamic object.
5979 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
5980 produced by scm_dynamic_func as the thing to call.
5982 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
5984 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
5985 (scm_register_module_xxx, scm_registered_modules,
5986 scm_clear_registered_modules): New functions.
5988 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
5990 * symbols.c (scm_sysintern): Renamed to
5991 scm_sysintern_no_module_lookup.
5992 (scm_sysintern): New function to take the place of the old
5993 scm_sysintern. It uses the current toplevel lookup closure to give
5994 the symbol its value. This is a temporary hack to put packages
5995 like gtcltk into their own module.
5996 (scm_can_use_top_level_lookup_closure_var): New variable to tell
5997 us whether `scm_top_level_lookup_closure_var' has been initialized
5999 * eval.c (scm_init_eval): Set it.
6001 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
6003 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
6004 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
6006 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
6008 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
6009 scm_sys_dup): deleted: FD capability will be added to other
6011 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
6012 scm_fd_free, fd_smob, scm_intern_fd.
6013 (scm_open): renamed from scm_sys_open. Return a port instead of
6014 an FD object. Make the mode argument optional.
6015 (scm_sys_create): deleted, it's just a special case of open.
6016 (scm_init_filesys): move interning of constants O_CREAT etc.,
6017 here (were previously using SCM_CONST_LONG macro).
6018 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
6020 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
6021 include "fports.h" and <stdio.h>
6022 (scm_stat, scm_select): don't support FD objects.
6024 * error.h: adjust scm_syserror_msg prototype.
6025 * error.c (scm_syserror_msg): take an extra argument for errno.
6026 Using the global value didn't always work, since it could be
6027 reset by procedure calls in the message or args arguments.
6029 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
6030 I don't understand why the check was there (and what about the
6033 * strop.c (scm_string_copy): allow shared substrings to be copied.
6035 * unif.h: corresponding change to prototypes.
6036 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
6037 recognize two new optional arguments: offset and length. Allow
6038 the port argument to be an integer (file descriptor, for scsh).
6039 Include <unistd.h> for "read" prototype.
6041 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6043 * socket.c: don't include filesys.h.
6045 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6047 * Makefile.am: add AWK=@AWK@ (?)
6049 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6051 Add a rule to generate errnos.c from errnos.
6052 * error.c (scm_init_error): include errnos.c.
6053 * errnos_cnvt.awk: new file, converts the list of errno codes to
6055 * errnos_get.c: new file.
6056 * errnos.default: new file, contains errnos to try if they can't
6057 be extracted from errno.h.
6058 * configure.in: if using GCC, try and extract errno codes from
6062 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6064 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6065 * Makefile.am: Made libguile into a libtool library.
6066 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6067 Set libtool_libs to indicate that libguile is a libtool library.
6068 See guile/ChangeLog for details.
6069 * .cvsignore: ignore "*.lo", the libtool library objects.
6071 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6073 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6074 use htons in getservbyport argument.
6076 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6078 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6079 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6082 * objprop.c (scm_object_property): No need to take the CDR of the
6083 value returned by scm_object_properties, since Aug 20 change.
6085 * configure.in: When checking for struct linger, #include
6086 <sys/types.h> as well as <sys/socket.h>. I've never known
6087 <sys/types.h> to cause any portability problems, and Solaris's
6088 <sys/socket.h> needs it.
6089 * configure: Rebuilt.
6091 I think the Sun compiler has chosen a perverse way to interpret
6092 ANSI declarations combined with K&R definitions. We'll
6093 appease it a little bit. But when it invades France, we fight.
6094 * print.c (scm_iprlist): Change 'tlr' argument to an int.
6095 * print.h (scm_iprlist): Here too.
6096 * numbers.c (scm_divbigdig): Change definition to match
6097 declaration in numbers.h.
6098 * unif.c (scm_makflo): Change definition to match declaration in
6101 * init.c (scm_boot_guile): Don't return the value of
6102 scm_boot_guile_1. This function doesn't return a value;
6103 scm_boot_guile_1 doesn't return a value (or return at all).
6105 * eval.c (unmemocopy): Add a semicolon to appease the Sun
6108 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
6109 compile. I have a feeling this function is a bad idea anyway ---
6110 one should always test for features, not systems.
6112 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
6113 semicolons. Only pure luck kept this from being noticed earlier.
6115 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
6117 * socket.c (scm_recvfrom): Added missing semicolon.
6119 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6121 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
6122 the buffer and start and end positions for scsh networking
6125 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
6127 * configure.in: Revert previous change to this file; the problem
6128 is due to transient automake weirdness.
6129 * configure: Rebuilt.
6131 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
6132 PLUGIN/guile.libs. configure generates the latter from the former.
6133 * Makefile.in: Rebuilt.
6135 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
6136 need this if we install scripts, like guile-snarf.
6137 * configure: Rebuilt.
6139 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6141 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
6143 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
6145 * socket.c (scm_addr_vector): fix faulty scm_listify.
6147 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
6149 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
6150 style block comment is no longer considered an error.
6152 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
6154 * PLUGIN/guile.libs.in: New file.
6155 * PLUGIN/guile.libs: Removed from repository.
6156 * configure.in: Create PLUGIN/guile.libs from
6157 PLUGIN/guile.libs.in. This is for including additonal libraries
6158 needed for dynamic linking.
6159 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
6160 instead of PLUGIN/guile.libs.
6162 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
6164 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
6166 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
6167 occurrences of the given element from the list, not just the
6168 first. This is how the Emacs Lisp functions behave, how the
6169 analogous Common Lisp functions behave, and (I believe) how the
6170 older Maclisp functions worked. I realize that this change may
6171 break code, but it seemed better to break it before the Guile
6174 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
6175 Their prototypes were already present in gc.h, but they weren't
6177 (scm_init_storage): Initialize scm_protects.
6178 * root.c (scm_protects): New element of scm_sys_protects.
6180 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
6182 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6184 * libguile.h: Added #include "libguile/net_db.h".
6186 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
6187 30 change. That file is only meant for communication between the
6188 configuration process and load.c. If code linked against libguile
6189 wants to get at the paths mentioned in libpath.h, it can call
6190 functions declared in load.h.
6192 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6194 * libguile.h: Removed #include "libguile/fdsocket.h"
6196 * net_db.c: Added #include <sys/socket.h>.
6198 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
6200 * filesys.c (scm_input_waiting_p): use select in preference to
6201 FIONREAD, since the latter doesn't detect EOF.
6202 Throw error if neither select nor FIONREAD available.
6204 * socket.c (scm_connect): take a port, not a fd object.
6205 (scm_fill_sockaddr): throw an error if fam is not recognised.
6206 (scm_bind): use scm_fill_sockaddr.
6207 (scm_listen): take a port, not a fd object.
6208 (scm_accept): take and return a port. return #f in the car if
6209 address can't be got
6210 (scm_sock_fd_to_port): new procedure.
6211 (scm_socket): use scm_sock_fd_to_port.
6212 (scm_addr_vector): throw error if unrecognised address type.
6213 take an extra argument with the calling procedure name.
6214 (scm_getsockname): take a port. return #f if address can't be got.
6215 (scm_getpeername): take a port. return #f if address can't be got.
6216 (scm_recvfrom): take a port. return #f for address component if can't
6218 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6219 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6221 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6223 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6224 use separate data pointers, to allow them to be designed
6225 independently and reused.
6226 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6227 Renamed from catch_body, catch_handler, and uncaught_throw; made
6229 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6231 (scm_catch): Use the above.
6232 (scm_throw): Don't bother printing a message for an uncaught
6233 throw; we establish a default handler in init.
6234 * throw.h (scm_internal_catch): Prototype updated.
6235 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6237 (struct scm_body_thunk_data): New structure, used as data
6238 argument to scm_body_thunk.
6239 * init.c (struct main_func_closure): New structure, packaging up
6240 the data to pass to the user's main function.
6241 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6242 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6243 scm_internal_catch to establish a catch-all handler, using
6244 scm_handle_by_message. This replaces the special-case code in
6246 (invoke_main_func): Body function for scm_internal_catch; invoke
6247 the user's main function, using the main_func_closure pointer to
6248 decide what to pass it.
6249 * root.c (struct cwdr_body_data): Remove handler_proc member.
6250 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6251 (cwdr_handler): Removed.
6253 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6255 * socket.h (SCM_P): update bind prototype.
6256 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6257 include "feature.h".
6258 (scm_socket): return a port, not a file descriptor object.
6259 include "fports.h" and <unistd.h>
6260 (scm_bind): take a port, not a file descriptor object.
6261 take an extra argument for address args.
6263 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6264 INADDR_NONE, INADDR_LOOPBACK.
6266 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6268 * init.c: include net_db.h and not fdsocket.h.
6269 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6271 * Makefile.am: corresponding changes.
6272 * socket.h: renamed from fdsocket.h, fix names.
6273 * net_db.h: renamed from socket.h, fix names.
6274 * socket.c: renamed from fdsocket.c.
6275 remove _sys from procedure names.
6276 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6277 add "socket" to features list.
6278 * net_db.c: renamed from socket.c.
6279 remove _sys from procedure names.
6280 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6281 add "net-db" to features list.
6282 include "net_db.h". don't include <sys/socket.h> or
6285 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6287 * tags.h (scm_tags): Removed comma at end of last enumerator.
6289 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6291 Don't use GCC extensions to allocate space for debugging frames.
6292 (Here he goes again! Why do we put up with this?!)
6293 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6294 an scm_debug_info structure, not an in-line array of them. Add
6295 'info' member, to say how many vect elements we've used, for eval
6297 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6298 a new variable debug_info_end to mark the end of vect, instead of
6299 the address of the 'info' pointer itself.
6300 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6301 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6302 (SCM_APPLY): Explicitly allocate space for debug.vect.
6303 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6304 * stacks.c: Adjusted for new debug frame structure.
6305 (RELOC_INFO, RELOC_FRAME): New macros.
6306 (stack_depth, read_frames): Use them, and new scm_debug_frame
6307 element 'info', instead of magically knowing that eval frames have
6308 an info pointer sitting after vect.
6309 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6311 (scm_init_stacks): Formatting tweaks.
6313 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6315 Give GCC more control flow information, so it can be sure that
6316 variables aren't used uninitialized.
6317 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6318 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6319 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6320 scm_misc_error): Tell GCC that these functions never return.
6321 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6322 out the field type, call abort if SCM_ASSERT returns, to placate
6324 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6325 scm_wta ever returns. We can't handle this case anyway, and this
6326 gives the optimizer more information.
6327 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6328 scm_wta ever returns.
6330 In some cases, the code is fine, but GCC isn't smart enough to
6331 figure that out; this usually happens when one variable is only
6332 initialized and used when a particular condition holds true, and
6333 we know that condition will never change within a given invocation
6334 of the function. In this case, we simply initialize the variables
6335 to placate the compiler, hopefully to a value which will cause a
6336 crash if it is ever actually used.
6337 * print.c (scm_iprin1): Initialize mw_pos.
6338 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6339 * throw.c (scm_ithrow): Initialize dynpair.
6340 * unif.c (scm_uniform_vector_ref): Initialize cra.
6341 * struct.c (init_struct): Initialize prot.
6342 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6344 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6345 if EXPR contains no expressions.
6347 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6349 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6350 cause an infinite loop (???). So much for the algebraic
6351 equivalency of variable-sized arrays and alloca...
6353 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6355 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6356 a SCM boolean, not a C boolean.
6358 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6360 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6361 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6362 rules for raising scm_mtrigger. Previously, unfortunate but not
6363 unlikely circumstances could result in almost constant invokation
6364 of the gc. Now, this situations should be less likely, but they
6365 are not prevented completely.
6367 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6369 * numbers.c (scm_fuck): Procedure removed; looks like old test
6371 * numbers.h: Prototype removed.
6373 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6375 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6376 array to a pointer, to match my Nov 21 change in eval.c.
6378 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6380 * libguile.h: Added #include "libguile/backtrace.h", #include
6381 "libguile/stacks.h".
6383 * strings.c (scm_string scm_make_string scm_string_ref
6384 scm_string_set_x scm_string_equal_p scm_string_append):
6385 Bugfix according to scm patch from Aubrey Jaffer:
6386 Corrected long-standing
6387 (not (eqv? (integer->char 128)
6388 (string-ref (make-string 1 (integer->char 128)) 0)))
6389 bug found by John Kozak <jk@noontide.demon.co.uk>.
6391 * strports.c, strports.h: Make scm_eval_0str return the value of
6392 the last expression evaluated (previously, it returned void).
6394 * strports.c, strports.h: New function: scm_read_0str. Does what
6397 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6399 * simpos.c (scm_getenv): return #f if string can't be found in the
6400 environment instead of throwing an exception, for compatibility
6401 with numerous other systems.
6403 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6405 * Makefile.am (.c.x): Use guile-snarf.
6406 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6408 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6410 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6412 * backtrace.c (scm_display_error_message): Made non-static, and
6413 renamed from display_error_message.
6414 * backtrace.h (scm_display_error_message): Added extern decl.
6415 * throw.c (uncaught_throw): Use it to display the error message.
6417 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6419 * inet_aton.c: Use #if 0, not #ifdef 0.
6421 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6423 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6424 to convert the returned value.
6425 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6426 the offset argument.
6428 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6430 Add new interface to catch/throw, usable from C as well as
6432 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6433 (scm_internal_catch): New function, replaces...
6434 (scm_catch_apply): Deleted.
6435 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6436 mechanism which is a bit more code, but can be used nicely from C
6437 and implement the Scheme semantics as well.
6438 (scm_internal_catch): This is the replacement; it's named after
6439 the analogous function in Emacs.
6440 (scm_catch): Reimplemented in terms of the above.
6441 (struct catch_body_data, catch_body, catch_handler): New
6442 functions, used by scm_catch.
6443 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6444 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6445 support for new cwdr.
6447 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6450 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6452 * acconfig.h: Added DYNAMIC_LINKING symbol.
6453 * configure.in: Add option and checks for dynamic linking.
6454 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6455 dynl.h: New files for dynamic linking support.
6456 * Makefile.am (libguile_a_SOURCES):
6458 (modinclude_HEADERS): Added "dynl.h".
6459 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6461 * init.c (scm_boot_guile_1): Call
6462 scm_init_dynamic_linking to initialize dynamic linking support.
6464 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6466 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6467 (as we Schemers say). It needs to be global, so that I can tweak
6468 it for the proper operation of unexec.
6469 (scm_boot_guile_1_live): New variable, see above.
6471 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6473 * guile-snarf.sh: Removed.
6474 * PLUGIN/guile.libs: Added dependency for -lm.
6475 * acinclude.m4: Renamed from aclocal.m4.
6476 * PLUGIN/greet: Removed.
6477 * Makefile.am, aclocal.m4: New files.
6478 * configure.in: Updated for Automake.
6480 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6482 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6483 and not top_level_lookup_thunk_var.
6485 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6487 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6489 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6491 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6492 Scheme function, instead of syntax. Single argument is now a
6495 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6497 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6498 scm_ra_divide): Properly terminate statements passed as arguments
6499 to IVDEP macros. (Thanks to Bernard Urban.)
6501 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6502 with non-constant sizes. (Thanks to Bernard Urban.)
6504 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6506 It's an "eval closure", not an "eval thunk." A thunk is a
6507 function of no arguments.
6508 * root.h (struct scm_root_state): Renamed
6509 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6510 (scm_top_level_lookup_closure_var): Renamed from
6511 scm_top_level_lookup_thunk_var.
6512 * root.c (mark_root): Uses changed.
6513 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6514 * init.c (scm_start_stack): Uses changed.
6515 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6516 Change scheme-visible name to *top-level-lookup-closure* from
6517 *top-level-lookup-thunk*.
6519 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6521 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6522 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6524 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6526 * gc.c (struct scm_heap_seg_data): Doc fixes.
6528 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6529 sweeping. Then, prepend each segment's free cells to its
6530 freelist, rather than wiping out the old value. (Thanks to Marius
6533 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6534 scm_check_freelist, scm_debug_newcell): New functions and
6535 variables, for debugging freelist problems.
6536 * pairs.h (SCM_NEWCELL): New debugging version added.
6537 * gc.h (scm_debug_newcell): Added extern declaration, used by
6538 debugging version of SCM_NEWCELL.
6540 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6542 On some systems <libc.h> conflicts with <unistd.h>, and should not
6543 be #included at all.
6544 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6545 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6546 * configure.in: Call it.
6547 * posix.c, filesys.c: Use its results to decide whether or not to
6549 * configure, scmconfig.h.in: Rebuilt with autoconf and
6552 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6554 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6555 pointer to the stdio stream before calling scm_setbuf0, so the
6556 latter will be able to retrieve it. I'm surprised this didn't
6557 segfault earlier. (Thanks to Christopher Lee.)
6559 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6561 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6564 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6566 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6567 number of stack narrowing specifier pairs. The first specifier in
6568 a pair controls inner border, the second the outer border. A
6569 number means cut that number of frames, a procedure object means
6570 cut until that object is found in operator position in a frame.
6572 * root.c (cwdr): Bugfix.
6574 * read.c: Recording of positions disabled by default.
6576 * procs.c (scm_closure_p): New function.
6578 * posix.c (scm_tmpnam): New function.
6580 * load.c: Added #include "throw.h".
6581 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6584 * load.c, load.h (scm_read_and_eval_x): New function.
6586 * eval.c: Renamed debug option "deval" to "debug".
6588 (scm_eval_x): `eval!' is no longer accessible from the scheme
6589 level. Motivation: We can't allow operations which introduce
6590 glocs into the scheme level. Guile's type system can't handle
6591 these as data. Use `eval' or `read-and-eval!' as replacement.
6593 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6594 SCM_CONSP since this is a macro!; Set vframe.prev to
6595 scm_last_debug_frame instead of 0. In this way we can look
6596 "above" the virtual start stack frame if we wish.
6597 (scm_debug_hang): New function: Useful for debugging Guile in
6598 certain tricky situations. Will probably be removed later...
6600 * debug.h: Changed semantics of debug option "backtrace". This
6601 option now only indicates whether we want automatic backtrace at
6604 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6606 * ports.c: #include "filesys.h"
6607 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6609 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6610 Motivation: This is system specific code which is related to file
6611 I/O. It also may use select. Added code by Gary Houston to
6612 detect presence of character in stdio buffers.
6614 * libguile.h: #include "libguile/libpath.h"
6616 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6617 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6618 SCM_SITE_DIR; Install libpath.h among the other include files.
6620 * load.c, load.h (scm_sys_package_data_dir): New function.
6622 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6624 * stacks.h: Bugfix: Don't use tail-array length field as stack
6625 length field! This screwed GC.
6627 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6629 * _scm.h: Added #ifndef around definition of macros min and max.
6631 * __scm.h: Added hooks for threads to plugin to in ints protection
6632 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6633 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6634 the main code in these macros duplicated and spread over multiple
6635 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6636 SCM_THREAD_SWITCHING_CODE.
6638 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6640 * snarf.h: New file.
6641 * guile-snarf.sh: New file.
6642 * Makefile.in (inner_h_files): Added snarf.h
6643 (ancillary, install, uninstall, distclean): Added actions for
6645 (.c.x): Use guile-snarf.
6646 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6647 (gen_c_files): Note that these depend on guile-snarf.
6648 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6649 now in "snarf.h". Added #include "snarf.h" to get them.
6650 * libguile.h: Added #include "snarf.h".
6651 (Patches applied and tweaked by Jim Blandy.)
6653 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6655 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6656 standards suggest against providing prototypes for system
6657 functions. Thanks to Greg Troxel.
6659 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6661 * strports.c (scm_eval_0str): New function.
6662 #include "read.h", to get prototype for scm_read.
6663 * Makefile.in (strports.o): Update dependencies.
6664 * strports.h: New prototype.
6666 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6667 scheme name from "int?" to "integer?". It seems to do the job.
6668 * numbers.h: Rename prototype too.
6669 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6672 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6673 scm_num_eq_p): Rename these according to R4RS conventions: call
6674 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6675 to making libguile R4RS compliant without ice-9...
6677 * load.c (scm_sys_search_load_path): Search for files under all
6678 extensions listed in the %load-extensions variable. If FILENAME
6679 is absolute, return it unchanged, without searching the load path.
6680 (scm_loc_load_extensions): New variable, pointing to
6681 %load-extensions' value cell.
6682 (scm_init_load): Initialize it, and the value it points to.
6683 (scm_primitive_load_path): Improve error reporting.
6685 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6686 of new Scheme variable %load-hook.
6687 (scm_primitive_load): Apply %load-hook to filename.
6689 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6691 * configure.in: add tests for figuring out whether buffered data
6692 is available in a FILE structure, which is needed by char-ready.
6694 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6697 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6698 exceptions using misc_error instead of syserror. It seems a bit
6699 odd to throw an exception if a string can't be found in the
6700 environment, but it's consistent with open-file, stat etc.
6701 (simpos.h): remove sys_ from getenv.
6703 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6704 occurs, throw an error instead of returning errno. Return value
6706 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6708 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6710 * filesys.c (scm_stat2scm): derive file type and permissions from
6711 the stat mode and append them to the returned vector.
6712 There isn't much overhead in doing this and it avoids the need to
6713 work with S_IRUSR et al. in Scheme.
6714 Define symbols scm_sym_regular etc.
6715 (scm_init_filesys): don't intern S_IRUSR etc.
6717 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6718 and s_primitive_load_path.
6720 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6722 * error.h: don't declare error symbols. prototype for scm_misc_error.
6724 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6727 * error.c: use SCM_SYMBOL to set up error keys.
6728 scm_misc_error: new procedure.
6730 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6732 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6733 between `#!' and `!#' is ignored.
6734 (skip_scsh_block_comment): New function.
6736 * feature.c (scm_set_program_arguments): New argument, FIRST.
6737 * feature.h: Update prototype.
6738 * init.c (scm_boot_guile_1): Pass new argument to
6739 scm_set_program_arguments.
6741 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6743 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6744 (scm_boot_guile): Call scm_set_program_arguments here, later than
6745 the old initialization.
6747 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6748 initialization procedure.
6749 - Delete in, out, err arguments; there are other perfectly good
6750 ways to override these when desired.
6751 - Delete result argument; this function shouldn't ever return.
6752 - Rename init_func argument to main_func, for less confusion.
6753 - Delete boot_cmd argument; main_func is more general.
6754 -Add 'closure' argument, to help people pass data to main_func
6755 without resorting to global variables.
6756 - Abort if reentered; don't bother returning an error code.
6757 - Call scm_init_standard_ports to set up the default/current
6758 standard ports; no need to pass them to scm_start_stack.
6759 - Remove code to evaluate the boot_cmd, and start the repl; let
6760 the user do something like that in main_func if they want.
6761 - Remove code to package up a return value; main_func can do any
6763 - Call exit (0), instead of returning.
6764 (scm_start_stack): Don't initialize the I/O ports here; that's
6765 weird. Delete in, out, err arguments. Move guts to
6766 scm_init_standard_ports, scm_stdio_to_port.
6767 (scm_init_standard_ports): New function, to set up current and
6768 default standard ports.
6769 (scm_start_stack, scm_restart_stack): Make these static.
6770 * init.h (scm_boot_guile): Adjust declaration.
6771 (scm_start_stack, scm_restart_stack): Remove externally
6772 visible declarations for these.
6773 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6775 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6776 written out several times in scm_start_stack.
6777 * fports.h: New declaration for the above.
6779 * feature.c (scm_set_program_arguments): New function.
6780 * feature.h: New declaration for the above.
6782 * ports.c: Formatting tweak.
6784 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6786 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6787 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6788 for obtaining the address of a car or cdr field. Motivation:
6789 &SCM_CXR make assumptions about the internal structure of the
6792 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6793 Motivation: see SCM_CXRLOC.
6795 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6796 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6797 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6798 Motivation: Safer use. Some other macros are defined in terms of
6799 these operations. If these are defined using the SCM_SETCXR
6800 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6801 to inefficiency and an <e1> with side-effects could potentially
6802 break. Also, these particular operations are heavily utilized in
6803 the garbage collector. In unoptimized code there will be a
6806 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6807 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6808 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
6809 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
6810 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
6811 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6812 vports.c: Cleaned up use of pairs: Don't make any special
6813 assumptions about the internal structure of selectors and
6814 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6815 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
6816 (Among other things, this change makes it easier to build Guile
6817 with certain compilers which have problems with casted lvalues.)
6819 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6821 * stacks.c: Improve selection of relevant stack frames when making
6822 a stack object. Introduce one level of indirection in the stack
6823 object to make it possible to "narrow" to a certain region of the
6824 stack. This facilitates making use of more clever algorithms (not
6825 implemented) for selecting relevant frames and gives a cleaner
6826 design since selection of frames can be done independently of
6827 extraction of frames from the real stack.
6828 (scm_stack_id): Also take #t as argument which means look at
6831 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
6832 Turn n_tail into an integer directly representing current number
6833 of frames in stack. Add field tail.
6835 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
6837 * debug.c (scm_make_memoized): Made it available at scheme level.
6838 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
6839 SCM_NIMP before applying heavier predicates in argument checking.
6840 (scm_local_eval): Also take memoized object as argument.
6842 * backtrace.c (scm_display_error): Just a safety measure: Stacks
6843 aren't created with zero length, but should such a strange
6844 creature suddenly turn up...
6846 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
6848 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
6849 `del', for the sake of C++ compilers. (Patch applied by JimB.)
6851 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
6853 * variable.c (scm_make_variable): Make the name hint optional, as
6855 (anonymous_variable_sym): Renamed from variable_sym. All uses
6858 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
6859 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
6860 of scm_primitive_load_path was also changed to
6861 "primitive-load-path", from "%try-load-path". Callers changed.
6862 We'd like to respect the convention that a function named
6863 "try-mumble" should behave just like the function called "mumble",
6864 but return #f instead of signalling some error.
6865 * load.h: Rename prototypes.
6867 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6869 * print.c (make_print_state, grow_print_state), print.h: Modified
6870 the print state representation: Don't use a tail array for
6871 recording of circular references. Resizing of the print state
6872 structure invalidates the print state pointer. To avoid passing
6873 around an indirect print state reference to all printing
6874 functions, we instead let the print state reference a resizable
6877 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
6879 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
6880 Don't crash when passed an improper list terminated by a
6881 non-immediate value.
6883 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
6885 Allocate data for structures on an eight-byte boundary, as
6886 required by the tagging system.
6887 * struct.c (alloc_struct): New function.
6888 (scm_make_struct, scm_make_vtable_vtable): Call it.
6889 * struct.h (scm_struct_n_extra_words): Bump to 3.
6890 (scm_struct_i_ptr): New "field".
6891 * gc.c (scm_gc_sweep): When we need to free the data, use the
6892 information stored by alloc_struct to find the beginning of the
6893 block allocated to the structure, so we can free it.
6895 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6897 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
6900 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
6901 (scm_debug_info): New member: id.
6903 * stacks.c: Stacks are now represented as structs; Stacks have an
6904 id given to them by `start-stack'.
6905 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
6907 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
6908 Changed stack representation.
6910 * debug.c (scm_procedure_name): Try procedure property `name' for
6911 compiled closures aswell.
6913 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
6915 * eval.c: scm_i_name moved to gsubr.c
6916 (scm_m_define): Record names of all kinds of procedure
6917 objects. (Earlier, only closures were recorded.)
6919 * procprop.h: Added declaration of scm_i_name.
6921 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
6922 (scm_make_gsubr): Record names of compiled closures.
6924 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6926 * debug.c, debug.h: Removed obsolete code.
6928 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
6929 stacks.c: Renamed regs --> scm_contregs.
6931 * print.c (scm_free_print_state): Cleanup print state before
6932 returning it to pool. It is better to do it here than in
6933 scm_prin1 since scm_prin1 is called often.
6935 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
6936 s_set_source_property_x): Check that first argument is a pair or a
6939 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
6940 scm_i_line, scm_i_column and scm_i_breakpoint global.
6942 * init.c: Added #include "backtrace.h" and #include "stacks.h".
6943 (scm_boot_guile_1): Added calls to scm_init_backtrace and
6946 * debug.h: Added debug object smob declaration and macro
6949 * configure.in: Build with backtrace.o and stacks.o if debug
6952 * Makefile.in: Added entries for new files: backtrace.c,
6953 backtrace.h, stacks.c and stacks.h.
6955 * symbols.c (scm_sym2ovcell): Fixed documentation.
6957 * _scm.h (min, max): Added.
6959 * async.c: Moved `min' macro to _scm.h.
6961 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
6962 SCM_BACKTRACE_INDENT.
6964 * eval.c: Added new debug options `maxdepth' and `indent'.
6966 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
6968 * print.h: Added selector SCM_PRINT_STATE.
6970 * print.c: New functions: scm_make_print_state,
6971 scm_free_print_state.
6973 * print.h: Added declarations for scm_make_print_state,
6974 scm_free_print_state.
6976 * debug.c (scm_m_start_stack): New acro.
6978 * debug.h: Small cleanup.
6980 * init.c (scm_boot_guile_1): Moved scm_init_debug below
6983 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

7003 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
7004 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
7005 declare functions with prototypes. (Patch thanks to Marius
7008 More prototype-related changes from Marius Vollmer:
7009 * gdb_interface.h: Wrapped header file in #ifdef/#endif
7010 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
7011 * ports.h (ptobfuns): Added prototypes. This means some casting in
7013 * fports.c: Added casts for initializations, since the functions
7014 are defined to take FILE * as their stream argument, not SCM.
7015 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
7016 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
7017 to `char *str_data' to conform to prototype.
7019 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7021 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
7023 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
7025 * stime.c, stime.h: use SCM_P method.
7027 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7029 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
7030 be given at least two arguments. Insist that lst's last element
7031 be a list, but don't make any requirements of its predecessors.
7033 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
7035 * eval.c (scm_nconc2last): Revert last change; there seems to be
7036 other stuff going on here.
7038 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7040 * eval.c (scm_nconc2last): Make sure that each element of lst
7041 (which is a list of argument lists, except for the tail) is a
7042 proper list, i.e., finite and terminated by '().
7044 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7046 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7049 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7050 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7053 * vectors.c (scm_make_vector): Fill vectors with the undefined
7054 value, to help make Guile Scheme code more portable to other
7057 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7058 * symbols.h, tags.h: Doc fixes.
7060 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7062 * async.c (scm_take_signal): Doc fixes.
7064 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7066 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7067 want to subtract it from the modulus; we just want to leave it
7070 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7072 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7075 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7077 * throw.c (scm_catch_apply): Finished implementation of
7080 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7082 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7084 (scm_init_filesys): set "i/o-extensions" feature.
7087 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7089 * Makefile.in (root.o): Correct dependencies.
7091 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7093 * Makefile.in: Added dependency entry for root.o.
7095 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
7096 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
7098 * init.c (scm_start_stack): Set initial root continuation number
7101 * procs.c: New function: scm_thunk_p.
7103 * procs.h: Added declarations of scm_thunk_p.
7105 * root.c: Renamed `call-with-new-root' -->
7106 `call-with-dynamic-root'.
7107 (cwdr): Removed allocation of new root state. This should be done
7108 separately by use of scm_make_root.
7109 (scm_apply_with_dynamic_root): New function: Does what it
7110 sounds like. Needed when spawning threads.
7112 * root.h: Added member last_debug_frame to root state.
7113 Added #include "libguile/debug.h"
7115 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
7116 arguments. The motivation is that code in root.c needs catch
7117 functionality, and we want to avoid code duplication.
7118 New functions: scm_catch, scm_lazy_catch. These are wrappers for
7119 scm_catch_apply. scm_lazy_catch is intended to introduce catch
7120 handlers that run without popping the stack into the dynwind
7123 * throw.h: Added prototypes for scm_catch_apply and
7126 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7128 * root.h (scm_root, scm_set_root): Decouple thread support details
7129 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
7130 SCM_SET_THREAD_LOCAL_DATA.
7132 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
7133 and tortoise scanning loop.
7135 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
7137 * Makefile.in: Rebuild dependencies.
7139 * libguile.h: #include "libguile/print.h" before "smob.h", since
7140 the latter uses the print_state structure.
7142 * throw.c (scm_ithrow): Use the correct variable when checking to
7143 see if a given element of scm_dynwinds is a valid catch.
7145 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
7146 structure, abort; don't just silently ignore the garbage.
7148 * _scm.h: #include "print.h" here, since it seems to be used just
7150 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
7151 strports.c, unif.h: Don't #include "print.h".
7153 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7155 * feature.h (scm_loc_features): Removed external declaration.
7156 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
7158 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7160 * feature.c (scm_init_feature): Added threads feature (needs to be
7161 initialized here, since features doesn't exist when
7162 scm_init_threads is called).
7164 * libguile.h: Added #include "libguile/../threads/threads.h".
7165 (This is a kludge to get thread support working. This should be
7168 * configure.in, acconfig.h: Added flags for thread support.
7170 * scmsigs.c: Define `signal' to be `pthread_signal' if using
7173 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
7174 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
7177 * _scm.h: Added conditional #include "threads.h"
7179 * __scm.h (SCM_ASYNC_TICK): Added call to macro
7180 SCM_THREADS_SWITCHING_CODE.
7182 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
7183 allocate the basic dynamic root object.
7184 (scm_boot_guile): Added call to scm_init_root.
7186 * root.c, root.h: Added root smob.
7187 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
7188 functions: Implements dynamic roots mostly according to spec in
7189 SCM manual. Main difference is that the second argument is a
7190 throw handler rather than an error "thunk".
7192 * root.h: Added declaration of scm_init_root.
7194 * root.c: Added #include "genio.h", #include "smob.h", #include
7195 "pairs.h", #include "throw.h", #include "dynwind.h", #include
7197 (scm_init_root): Added #include "root.x".
7199 * throw.c: Added #include "stackchk.h"
7200 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
7201 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
7202 can be used in scm_call_with_new_root; Added reenabling of stack
7203 checking when catching a throw.
7205 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
7207 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
7209 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
7210 element is not found, as per R4RS.
7212 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7214 * list.c: Doc fixes throughout.
7216 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7218 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7219 declare the char * to be const. Avoids a warning in rgx.c.
7221 * ports.h: spelling fix.
7223 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7226 * load.c (scm_sys_try_load_path): throw an error if file not found
7227 (like it says it in NEWS).
7229 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7231 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7232 PROPS slot to '(), not #f; it's an empty alist.
7234 * throw.h, throw.c: Use SCM_P instead of #if hair.
7236 Remove special support for uncaught throws; see throw.c for
7238 * throw.c (uncaught_throw): New function.
7239 (scm_ithrow): Call uncaught_throw if we don't find a throw
7240 target; don't mess with scm_bad_throw_vcell.
7241 (scm_bad_throw_vcell): Variable deleted.
7242 (scm_init_throw): Don't initialize it.
7244 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7247 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7249 * numbers.c (scm_istr2int): If the number is short (as most
7250 numbers are), just call scm_small_istr2int to deal with it.
7251 (scm_small_istr2int): New function, created by un-#ifdefing the
7252 non-bignum version of scm_istr2int and renaming it.
7254 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7256 * load.c (scm_sys_try_load): don't check whether value returned
7257 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7258 Change the Scheme name from %try-load to primitive-load.
7260 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7261 Can avoid passing a message, allowing it to be derived in the
7262 error handler (e.g., if we want to throw to the key both from
7265 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7267 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7268 references now have a new appearance which is more compact and
7269 also gives a clue about what the target of the reference is.
7270 By setting parameters in the print state, more fancy printing can
7271 be achieved. This is used by the (not yet commited) backtrace
7274 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7276 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7279 * print.c: Added #include "struct.h". Removed function
7282 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7283 scm_iprin1. Removed prototype for scm_prlist.
7285 * arbiters.c (prinarb),
7286 async.c (print_async),
7287 debug.c (prindebugobj, prinmemoized),
7288 eval.c (prinprom, prinmacro),
7289 filesys.c (scm_fd_print, scm_dir_print),
7291 mallocs.c (prinmalloc),
7292 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7293 smob.h (scm_smobfuns),
7294 srcprop.c (prinsrcprops),
7296 unif.c, unif.h (scm_raprin1, rapr1),
7297 variable.c (prin_var): Changed argument `int writing' to
7298 `scm_print_state *pstate'.
7300 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7301 that it will be called before scm_init_print.
7303 * print.c (scm_prin1): Print states are now allocated when calling
7304 scm_prin1 and then passed around to all printing functions as an
7305 argument. A cache `print_state_pool' enables reuse of print
7307 (scm_make_print_state): New function.
7308 (scm_iprin1): Adaption to print states.
7309 (scm_iprlist): An initial "hare and tortoise" scan brings down
7310 time complexity to O (depth * N). (Better time complexity will be
7311 achieved when the printing code is completely rewritten.)
7313 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7315 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7316 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7317 it gets done whether or not the cache variable has a value.
7319 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7321 Distinguish #f and ().
7322 * __scm.h: #undef SICP.
7323 * pairs.h (SCM_EOL): Delete this definition, equating it with
7325 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7326 the value it used to have. Doc fixes, too.
7328 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7330 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7331 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7332 Lord's implementation of structs, allowing for tail arrays as
7333 described in the manual. Also fixed some bugs. (Both the interface
7334 and the implementation should be improved.)
7336 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7338 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7339 People who whish to see the source can do `(print-enable 'source)'.
7340 Removed #ifdef DEBUG_EXTENSIONS.
7342 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7344 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7345 integer (assuming for now accepting an integer is a good thing).
7347 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7348 %S will be used instead for write'ing arguments.
7350 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7351 asserts. fix a few other asserts.
7352 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7353 scm_uniform_vector_ref, scm_array_set_x,
7354 scm_dimensions_to_unform_array): change args in
7355 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7356 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7357 scm_substring_fill_x): likewise.
7358 gsubr.c (scm_gsubr_apply): likewise.
7359 eval.c (SCM_APPLY): likewise.
7361 * eval.c (4 places): replace scm_everr with lgh_error or
7364 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7365 scm_memory_error): new procedures.
7366 scm_everr: deleted. can use scm_wta, dropping first two args.
7367 scm_error: convert NULL subr to SCM_BOOL_F.
7369 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7372 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7375 * error.c, error.h: new error keys: scm_arg_type_key,
7376 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7378 scm_wta: reimplement using lgh_error instead of scm_everr.
7380 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7382 * gdbint.c: scm_lread now has one more argument.
7384 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7385 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7386 loading source from non-file ports, which, e. g., happens when
7387 using the Emacs interface).
7389 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7392 * read.c: Added code for recording of positions of source code
7393 expressions; New functions: recsexpr, scm_lreadrecparen;
7394 _scm_make_srcprops --> scm_make_srcprops
7395 (scm_flush_ws): Removed updating of positions counters. This work
7396 is already done by scm_gen_getc
7398 * read.h: Added prototype for scm_lreadrecparen
7400 * print.c: Added #include "alist.h"
7402 * eval.c: Added #include "hash.h"

7410 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7411 --> scm_make_srcprops
7413 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7414 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7415 function calls in the definition of the whash access macros.
7417 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7419 * init.c (scm_boot_guile): Add level of indirection to
7420 scm_boot_guile_1() to ensure that stack base pointer is properly
7421 initialized. There was no guarantee that variable i was the
7422 highest/lowest variable on stack (i.e. the call frame of
7423 scm_boot_guile was not completely protected from gc).
7425 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7427 * ports.h (scm_port_table): put back file_name, it will be used to
7428 support debugging. Undo related changes in fports.c, ioext.c,
7431 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7433 * ports.h (scm_port_table): remove file_name member for now, it seems
7435 * fports.c (scm_open_file): don't set file_name in PTAB.
7436 (prinfport): don't use file_name in PTAB.
7437 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7438 * ports.c (scm_add_to_port_table): don't intialize file_name.
7439 (scm_port_file_name): remove for now.
7440 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7442 * fports.h (scm_mkfile): prototype deleted.
7443 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7445 * debug.c, unif.c: use scm_out_of_range instead of
7446 wta for range errors (ASSERT still needs work).
7448 * error.c, error.h (scm_out_of_range): new procedure.
7450 * error.c, error.h (scm_out_of_range_key): new key.
7452 * posix.c (scm_sync): #else was missing.
7454 * error.c, error.h: append _key to names scm_num_overflow and
7457 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7458 of consing an empty list.
7459 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7460 of macros, saves code and string space.
7461 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7462 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7463 lower case. Rename scm_syserror_m to scm_syserror_msg.
7464 error.h: prototypes for new procedures.
7466 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7468 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7470 * error.c, error.h: setup scm_num_overflow key.
7472 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7473 Remove definition of SCM_OVSCM_FLOW.
7475 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7477 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7478 explicit message and args.
7480 * error.c, error.h, __scm.h: change system_error_sym to
7483 * error.c (system_error_sym): remove leading %% from the Scheme name
7486 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7488 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7490 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7491 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7492 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7493 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7494 renamed. (These were introduced by unsupervised name
7497 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7499 * print.c: Added code for detection of circular references during
7500 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7501 a hook for printing of closures (accessible via print options).
7502 This leads to a split of calls to scm_iprin1 into two classes:
7503 elementary print operations (e. g. the code which prints a smob)
7504 still use scm_iprin1 while top level calls (like scm_display) use
7505 scm_prin1. scm_prin1 begins by clearing the data structure used
7506 to record reference information.
7508 * print.h: Added declarations of scm_prin1 and scm_prlist.
7510 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7512 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7514 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7516 * error.c (err_head): scm_iprin1 --> scm_prin1
7518 * debug.c: Adjusted header comment.
7522 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7524 * strerror.c: Doc fix.
7526 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7528 * gdbint.c (gdb_read): Now possible to run during GC.
7529 (unmark_port, remark_port): New functions.
7531 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7533 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7534 of allocating a new string object. Also, increase size by
7535 the factor 2 instead of 1.5.
7537 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7539 * __scm.h (SCM_P): Corrected to run under traditional C.
7541 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7544 * async.c: Calls to scm_sysintern corrected.
7546 * async.h (scm_async_clock): Redundant declaration removed.
7548 * continuations.c (scm_dynthrow): Redundant declaration removed.
7550 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7551 Definition typos corrected.
7553 * debug.h: Missing declarations of functions in debug.c added
7556 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7557 Missing declarations to functions in eval.c added.
7559 * filesys.c: Possibly uninitialized variable rv.
7561 * gc.h (scm_object_addr, scm_unhash_name): Missing
7562 declarations of functions defined in gc.c added.
7564 * genio.c: Possible typos str_data -> wstr_data. ???
7566 * genio.c: Possibly unintended shadowing of local variable
7567 `int c' (gotos out of scope of inner `c'). ???
7569 * init.c: Uninitialized `SCM last' may be used.
7571 * ioext.h: (scm_sys_isatty_p): Typo.
7573 * list.h (scm_list_head): Missing prototype for function in
7576 * numbers.c (scm_two_doubles): Changed from extern to static
7577 (is used only within numbers.c).
7579 * numbers.h: Repeated declarations removed.
7581 * ports.h (scm_close_all_ports_except): Declaration for the
7582 function defined in ports.c added.
7584 * posix.h: Missing declarations added.
7586 * procs.h (scm_make_subr_opt): Missing declaration added.
7588 * socket.h (scm_sys_gethost): Missing declaration added.
7590 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7592 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7593 Missing declarations added.
7595 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7597 * struct.c: Uninitialized variable `SCM answer' may be used.
7599 * unif.c (l2ra): Declaration prototype.
7601 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7602 defined in ramap.c).
7604 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7605 Redundant declarations removed (they are in ramap.h).
7607 * variable.h (scm_make_udvariable,
7608 scm_make_undefined_variable): Declaration corrected to
7609 correspond variable.c.
7611 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7612 Missing declarations added.
7614 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7616 * Makefile.in (distclean): Don't forget to delete fd.h.
7618 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7620 * fd.h.in, tags.h: Trivial cleanups.
7622 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7623 marksweep.h just declared functions from gc.c.
7624 * gc.h, libguile.h: Don't #include "marksweep.h".
7625 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7626 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7627 dependencies updated.
7629 * libguile.h: Don't #include "files.h"; it's been deleted.
7631 * files.c (scm_sys_delete_file): Moved to filesys.c.
7632 File is now empty; deleted.
7634 * filesys.c: scm_sys_delete_file is now here. Remove
7635 #if's; they seem to rely on remnants of an old portability
7636 regimen. If the problems come up again, solve them properly,
7637 using autoconf. Specifically: Don't test M_SYSV, and #define
7638 remove to be unlink if it's #defined; don't use remove just
7639 because HAVE_STDC_HEADERS is #defined.
7640 * filesys.h: Add declarations for scm_sys_delete_file.
7641 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7642 files.o, files.h, files.c, and files.x.
7643 * init.c: Don't #include "files.h", and don't call scm_init_files.
7645 Use SCM_P instead of PROTO; the latter intrudes on the user's
7647 * params.h: Deleted; definition of SCM_P moved to...
7648 * __scm.h: ... here, where it replaces PROTO macro.
7649 * libguile.h, smob.h: Don't #include "params.h".
7650 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7651 smob.h: Fix prototypes accordingly.
7652 * Makefile.in: Update dependencies.
7653 (inner_h_files): Remove params.h.
7655 * gc.c: #include "gc.h"; every module should include its header,
7656 to let the compiler cross-check the declarations against the
7659 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7660 simpos.h: #include "libguile/__scm.h".
7662 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7664 * init.c: Don't forget to #include smob.h and init.h.
7665 * Makefile.in: Dependencies updated.
7667 * smob.h: Use PROTO instead of #if __STDC__.
7669 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7671 * __scm.h: Doc fixes.
7673 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7674 <angles>; this allows `make depends' to work properly.
7676 * libguile.h: #include smob.h and pairs.h before the others; they
7677 define typedefs used by other headers.
7679 C files should #include only the header files they need, not
7680 libguile.h (which #includes all the header files); the pointless
7681 recompilation was wasting my time.
7682 * Makefile.in (all .o dependency lists): Regenerated.
7683 * libguile.h: Don't try to get a definition for size_t here...
7684 * __scm.h: Do it here.
7685 * _scm.h: Since this is the internal libguile header, put things
7686 here that all (or a majority) of the libguile files will want.
7687 Don't #include <libguile.h> here; that generates dependencies on
7688 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7689 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",

7784 * vectors.c: Get "vectors.h", "eq.h".
7785 * version.c: Get "version.h".
7786 * vports.c: Get "vports.h", "fports.h", "chars.h", "eval.h".
7787 * weaks.c: Get "weaks.h".
7789 * stackchk.h: #include "libguile/debug.h",
7791 * print.h, read.h: #include "options.h", since everyone who uses
7792 either of these files will need that.
7794 * smob.h: #include "ports.h", "genio.h", and "print.h", since
7795 anyone who uses this file will need them to define the smob
7796 printing functions. Also, get markers.h, since people will need
7797 to #define the mark functions.
7799 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
7800 * ports.h: ... to here.
7802 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7803 don't rely on archaic C default type rules.
7805 * fports.h: #include "libguile/ports.h", since you need that in
7806 order to parse this.
7808 * genio.h: #include "libguile/print.h", because you need that to
7809 parse this; don't bother #including "ports.h", since print.h gets
7812 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7814 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7815 this; it's now a reference to an element of *scm_root.
7817 * debug.h: Don't #include "options.h"; the compiler won't be able
7818 to find that once the headers are installed; instead, #include
7819 "libguile/options.h".
7820 * gc.h: Same, with marksweep.h.
7821 * mbstrings.h: Same, with symbols.h.
7822 * scmhob.h: Same, with _scm.h.
7823 * smob.h: Same, with params.h.
7825 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
7826 C files; there's no need for this, and it forces recompilations
7829 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
7831 * error.c (scm_error): declare scm_error_callback.
7833 * error.h: prototype for scm_error_callback.
7835 * __scm.h: define lgh_error.
7836 (SCM_SYSERROR): redefine using lgh_error.
7838 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
7840 * error.c (scm_error): new procedure.
7842 * error.h: prototype for scm_error.
7844 * Makefile.in (install): install scmconfig.h from the current
7845 directory, not $(srcdir).
7847 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7849 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7850 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7851 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
7852 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
7853 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
7854 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
7855 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
7856 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
7857 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7858 vports.h, weaks.h: #include "libguile/__scm.h", not
7859 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
7860 dependencies are within libguile properly.
7862 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7864 * Makefile.in (.c.x): Simplify; there's no need to run this rule
7865 when scmconfig.h doesn't exist.
7867 * load.c (scm_sys_try_load): Correct spelling.
7869 * feature.c (scm_loc_features): Make this static.
7871 * Makefile.in (libpath.h): Omit trailing slash from path. We
7872 shouldn't require it of users, so why put it here?
7874 Move code to initialize and search %load-path from ice-9 to C
7875 code, so we can use the load-path to find the ice-9 boot code;
7876 this makes it easier to run Guile without installing it. See
7877 corresponding changes in guile/Makefile.in.
7878 * feature.c: Move stuff concerned with the load path to load.c.
7879 (scm_compiled_library_path): Deleted.
7880 Don't #include libpath.h here.
7881 * feature.h: Don't mention scm_compiled_library_path.
7882 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
7883 <sys/stat.h>, and <unistd.h> (if present).
7884 (R_OK): #define if the system hasn't deigned to.
7885 (scm_loc_load_path): New variable.
7886 (scm_init_load_path, scm_sys_search_load_path,
7887 scm_sys_try_load_path): New functions.
7888 (scm_init_load): Initialize scm_loc_load_path to point to the
7889 value cell of the Scheme %load-path variable.
7890 * load.h: Add declarations for scm_sys_search_load_path,
7891 scm_sys_try_load_path.
7892 * init.c: Call scm_init_load_path.
7893 * Makefile.in (feature.o, load.o): Dependencies updated.
7895 * load.c, load.h: Rewrite using PROTO macro.
7897 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7899 * gc.c (scm_cellp): New function: C predicate to determine if an
7900 SCM value can be regarded as a pointer to a cell on the heap.
7902 * gc.h: Added declaration of scm_cellp.
7904 * gdb_interface.h: New file: The GDB interface header from the GDB
7907 * gdbint.c: New file: GDB interface.
7909 * gdbint.h: New file: GDB interface.
7911 * libguile.h: Added #include <libguile/gdbint.h>.
7913 * init.c (scm_boot_guile): Added scm_init_gdbint.
7915 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
7916 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
7917 found if object files and source are kept separate).
7919 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
7921 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
7923 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
7925 * configure.in: Don't substitute the values of TCL_SRC_DIR and
7926 TK_SRC_DIR; they're not relevant any more.
7928 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
7929 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
7931 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
7933 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
7934 search path, so we can find the <libguile/MUMBLE.h> headers.
7936 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
7938 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
7939 implicit in the .c.o rule.
7940 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
7943 Put the library path in a header file, instead of passing it on
7944 the command line in every compilation.
7945 * Makefile.in (libpath.h): New target.
7946 (feature.o): Depend on libpath.h.
7947 (clean): Delete libpath.h.
7948 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
7949 * feature.c: ... #include "libpath.h" here.
7950 * .cvsignore: Ignore libpath.h.
7952 Don't install the unwashed masses of Guile header files in the
7953 main #include path; put most of them in a subdirectory called
7954 'libguile'. This avoids naming conflicts between Guile header
7955 files and system header files (of which there were a few).
7956 * Makefile.in (pkgincludedir): Deleted.
7957 (innerincludedir): New variable; this and $(includedir) are enough.
7958 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
7959 (installed_h_files): Divide this up. Now this variable lists
7960 those header files which should go into $(includedir) (i.e. appear
7961 directly in the #include path), and ...
7962 (inner_h_files): ... this new variable says which files appear in
7963 a subdirectory, and are referred to as <libguile/mumble.h>.
7964 (h_files): List them both.
7965 (install): Create innerincludedir, not pkgincludedir. Put
7966 the installed_h_files and inner_h_files in their proper places.
7967 (uninstall): Corresponding changes.
7968 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7969 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7970 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
7971 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
7972 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
7973 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
7974 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
7975 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
7976 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7977 vports.h, weaks.h: Find __scm.h in its new location.
7978 * __scm.h: Find scmconfig.h and tags.h in their new locations
7979 (they're both "inner" files).
7981 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
7983 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
7985 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7987 * posix.c: Doc fixes.
7989 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
7991 * socket.c: Don't include a prototype for inet_aton; just use a
7992 K&R style declaration, to avoid warnings but minimize the chance
7993 of conflicts with the system.
7995 On NextStep, <utime.h> doesn't define struct utime, unless we
7996 #define _POSIX_SOURCE before #including it.
7997 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
7998 * acconfig.h: New comment text for above CPP symbol.
7999 * configure.in: Call it.
8000 * posix.c: #define _POSIX_SOURCE if it seems necessary.
8002 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
8004 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
8005 testing for __EMX__.
8007 * posix.c: #include <libc.h>, if it exists.
8009 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
8010 don't even know if the latter exists.
8012 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
8013 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
8014 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
8016 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
8018 (scm_init_posix): Use them when initializing the Scheme constants
8021 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
8023 * Makefile.in (libdir, includedir, bindir): Use the
8024 autoconf-supplied values, instead of deriving them ourselves.
8025 (pkgincludedir, datadir, pkgdatadir): New variables.
8026 (install, uninstall): Put the header files in a special
8027 subdirectory, not in the main search path.
8029 * Makefile.in (ALL_CFLAGS): Provide the proper value for
8030 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
8032 * Makefile.in (IMPLPATH): Deleted; never used.
8034 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
8035 on the Tcl/Tk source any more.
8036 (INCLUDE_CFLAGS): Remove references to the above.
8038 * Makefile.in (version.o): Corrected dependencies.
8040 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8042 * libguile.h: #include "version.h"
8044 * init.c (scm_boot_guile): Call scm_init_version.
8045 * gscm.c (gscm_run_scm): Call scm_init_version.
8047 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8048 GUILE_VERSION): AC_DEFINE these.
8049 (acconfig.h): #undef the above symbols.
8051 * Makefile.in (libobjs): Add version.o.
8052 (installed_h_files): Add version.h.
8053 (c_files): Add version.c.
8054 (gen_c_files): Add version.x.
8055 (version.o): New rule.
8056 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8057 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

8061 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
8062 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,

8065 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
8066 weaks.o): Add version.h to dependency lists.
8067 (markers.o): Remove duplicate rule.
8069 * version.h: New file.
8071 * version.c: New file.
8073 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8075 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8076 array; use it appropriately. Since GCC is quite happy to
8077 subscript functions, it never warned us about this; we should use
8078 -Wpointer-arith in the future. I guess we never tested
8081 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8083 * socket.c: Doc and copyright fixes.
8085 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8087 * debug.c: Fixed and improved gdb support.
8089 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8091 * socket.c: Added declaration of inet_aton to avoid compiler
8092 warning. (Hope this solution is correct.)
8094 * stime.c: Added declaration of ftime. (This is missing in
8097 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
8099 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8101 * Makefile.in (c_files): add strerror.c.
8103 * strerror.c: new file from Emacs' sysdep.c.
8104 maybe configure should also check for sys_errlist.
8106 * configure.in (AC_REPLACE_FUNCS): add strerror.
8108 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8110 * debug.c (scm_init_debug): Added initialization for
8111 scm_evaluator_traps.
8113 * debug.h, debug.c: Various name changes.
8114 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
8115 "debug-options-interface". See commentary in options.c.
8117 * options.h, options.c: Options now have documentation strings.
8118 Also added a long explanatory commentary.
8120 * eval.c, print.h, print.c, read.h, read.c: Modifications to
8123 * gscm.c, init.c, root.c, throw.c: Bug fixes:
8124 last_debug_info_frame is now updated in all cases.
8126 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
8129 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8131 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
8132 Added option STACK_CHECKING.
8134 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8136 * Makefile.in: Added {debug,options,srcprop}.{h,c}
8138 * __scm.h: Removed symbols for debugging support.
8140 * acconfig.h: Added symbols for debugging support.
8142 * configure.in: Added user option for debugging support.
8143 --enable-debug will include the debugging code into libguile.a.
8145 * continuations.c (scm_make_cont): Enlarged the #if 0 around
8146 scm_relocate_chunk_to_heap.
8148 * debug.c: New file: low-level debugging support. It also
8149 includes support for debugging with gdb. (The extensions to gdb
8150 are written by Per Bothner at Cygnus.)
8152 * debug.h: New file: low-level debugging support.
8154 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
8155 argument pairs. Extensive modifications to the debugging
8156 evaluator. Added "SECTION:" commentaries to clarify what happens
8157 when, during double compilation. Renamed EVALIMP --> EVALIM.
8158 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
8159 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
8160 the beginning of the file. New procedure: scm_unmemocopy.
8161 Added some global state variables needed by the debugging
8162 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
8163 check_entry, check_apply, check_exit, debug_options and
8164 evaluator_traps. New acro: undefine.
8166 * eval.h: Renamed EVAL --> XEVAL.
8168 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
8169 --> scm_make_weak_key_hash_table.
8171 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
8172 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
8174 * libguile.h: Conditionally include debug.h
8176 * objprop.c (scm_object_properties, scm_set_object_properties_x):
8177 scm_object_properties shouldn't return handle. `handle' now gets
8178 initialized in scm_set_object_properties_x. scm_object_properties
8179 doesn't any longer create an entry in scm_object_whash.
8181 * options.c: New file: handling of run time options.
8183 * options.h: New file: handling of run time options.
8185 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
8187 * print.c: New procedure: scm_print_options
8189 * print.h: Defines for print options.
8191 * read.c: New procedure: scm_read_options
8193 * read.h: Defines for reader options.
8195 * root.h: Added scm_source_whash among scm_sys_protects.
8197 * srcprop.c: New file: source properties.
8199 * srcprop.h: New file: source properties.
8201 * throw.c (jbsmob): Jump buffers are now correctly allocated.
8202 (Bug found by A. Green.)
8204 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8206 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8208 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
8210 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8212 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8213 and should be called by the final client.
8215 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8217 * gc.h: Use the PROTO macro when declaring functions.
8218 * gc.c: Use the PROTO macro when declaring static functions.
8219 Remove the CPP hair around function definitions.
8221 * gc.c (scm_init_storage): Initialize scm_asyncs.
8223 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8224 preprocessor symbol; "__scm.h" is where it might get #defined.
8225 * __scm.h: Similar: #include <scmconfig.h> before testing
8228 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8230 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8232 * init.c (scm_boot_guile): Add init_func argument; call
8233 (*init_func) instead of calling scm_appinit; it's ucky to
8234 hard-code names for the user's procedures.
8235 * init.h (scm_boot_guile): Adjust declaration.
8237 * __scm.h (PROTO): New macro, for declaring functions with
8240 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8241 eliminate all the __STDC__ conditionals.
8242 (scm_boot_guile): Add declaration.
8243 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8244 Remove __STDC__ conditionals around function definitions; the
8245 declarations in init.h will provide the same information, more
8248 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8249 complain about it in the error message; the error message is
8250 adequate without that note, and there's nothing the user can do
8253 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8255 * Makefile.in (ancillary): Drop def.sed.
8257 * posix.c (scm_init_posix): Use numeric values, rather than
8258 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8259 F_OK. The symbols aren't available on some systems, and I'm
8260 pretty sure their values are fixed by common widespread practice.
8261 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8263 More functions unavailable on some systems.

8448 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8450 * gscm.h: gscm_mkarray eliminated (presumably was not being used

8457 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8459 * ports.c: removed functions relating to the mapping between ports

8468 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8469 handled correctly (SCM_FREEP was applied to them) -- test for

8664 set the multi_byte flag correctly in symbols. This is wrong.
8665 intern_obbary_soft and msymbolize should take an extra parameter.

8821 can turn into an obscure gc bug.
8823 * chars.c (scm_char_p): fixed PROC call.
8825 * gscm.h (gscm_vset): use scm_vector_set_x not (the missing)
8828 Tue Jan 23 13:29:40 1996 Tom Lord <lord@beehive>
8830 * elisp.c (new file): dynamic scoping and other bits for
8831 elisp. Don't use this yet unless you specificly want to
8832 hack on elisp emulation.
8834 * dynwind.c (scm_dowinds): When entering or leaving a dynamic
8835 scope created by scm_with_dynamic_bindings_operation_x, swap
8836 the bindings of that scope with the corresponding globals.
8838 * continuations.c (scm_make_cont): when a continuation is captured,
8839 relocate the continuation stack chunks registered on the wind chain
8842 Sun Jan 21 19:31:17 1996 Tom Lord <lord@beehive>
8844 * eval.c (SCM_CEVAL): if the function position evaluates
8845 to a macro, process it accordingly. (Previously, macros were
8846 handled only if the function position was a symbol naming a
8847 variable bound to a macro).
8849 Sat Jan 20 23:21:37 1996 Tom Lord <lord@beehive>
8851 * eval.c (scm_m_set): allow multi-variable set! like
8854 Wed Dec 6 02:40:49 1995 Tom Lord <lord@beehive>
8856 * ports.h fports.c vports.c marksweep.c gc.c strports.c: moved the
8857 STREAM of ports into the port table and replaced it with a
8860 * repl.c (iprin1): added tc7_mb_string -- same as tc7_string.
8862 * marksweep.c (scm_gc_mark): added tc7_mb_string -- same as tc7_string.
8864 * mbstrings.c (new file): functions on multi-byte strings.
8866 * tags.h (scm_typ7_string, scm_typ7_mb_string): added a tag
8867 for multi-byte strings. Moved the string tag.
8869 * chars.h chars.c repl.c (many functions): made scm_upcase and
8870 scm_downcase functions that are safe for extended character sets.
8872 Changed the range of integer->char.
8874 Changed the type of SCM_ICHR.
8876 Tue May 16 17:49:58 1995 Mikael Djurfeldt <mdj@sanscalc.nada.kth.se>
8878 * guile.c: Changed init file name from "SCM_INIT_PATH" to
8881 Sun Aug 6 15:14:46 1995 Andrew McCallum <mccallum@vein.cs.rochester.edu>
8883 * guile.c (gscm_is_gscm_type): New function. (Without this how will we
8884 know that it's safe to pass an object to gscm_get_type?)
8885 (gscm_get_type): Fix tyop in error message.
8887 * variable.c (scm_variable_ref): fixed assertion test.
8888 (Robert STRANDH <strandh@labri.u-bordeaux.fr>)
8890 * gscm.h: fixed several prototypes, notably gscm_vref.
8891 Add gscm_is_eq and temporarily commented out gscm_eq (see
8892 the note in gscm.h near gscm_eq if this change effects your
8894 (Reported by Mark Galassi <rosalia@sstcx1.lanl.gov>)
8896 * pairs.c (scm_obj_length): see next entry.
8898 * gscm.h (gscm_obj_length): A way to get an integer
8899 length for lists, strings, symbols (treated as strings),
8900 and vectors. Returns -1 on error.
8902 * eq.c (scm_equal_p): fixed smob case.
8903 (William Gribble <grib@arlut.utexas.edu>)
8905 * Makefile.in (X_CFLAGS): defined.
8906 (William Gribble <grib@arlut.utexas.edu>)
8908 * gscm.h (gscm_2_double): provided now
