1 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
3 Cleanup and simplification of generic method dispatch.
4 Also, the quadruple representation of entity and operator
5 procedures has been replaced with single.
7 * tags.h (SCM_IM_HASH_DISPATCH): Removed.
9 * print.c (scm_isymnames): Removed #@hash-dispatch.
11 * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here
12 from eval.c; Support 0 arity methods.
13 (scm_set_object_procedure_x): Removed scm_sym_atdispatch;
14 (scm_apply_generic_env): Removed.
15 Replaced slots proc0-3 with procedure.
17 * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1,
18 SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by
19 SCM_OPERATOR_PROCEDURE.
20 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2,
21 SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE.
23 * struct.c, struct.h: Replace 4 procedure slots with one.
24 (scm_struct_i_procedure): Replaces scm_struct_i_procedure.
26 * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of
29 * eval.c (scm_sym_args): Removed.
30 (SCM_CEVAL): Simplified entity application.
31 Moved dispatch code to objects.c.
33 * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics.
35 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
37 * sort.c (closureless): Use scm_eval_body.
39 * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure
40 with a symbol as last form was first called normally and then via
41 `map' or some other mechanism using primitive apply, an ILOC was
44 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
46 This change extends the representation of primitive procedures
47 with more data fields, e.g. a place for documentation and true
50 * procs.c, procs.h (scm_subr_entry): New type: Stores data
51 associated with subrs.
52 (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS,
53 SCM_SUBR_DOC): New macros.
54 (scm_subr_table): New variable.
55 (scm_mark_subr_table): New function.
57 * init.c (scm_boot_guile_1): Call scm_init_subr_table.
59 * gc.c (scm_gc_mark): Don't mark subr names here.
60 (scm_igc): Call scm_mark_subr_table.
63 This change implements a scheme for letting a generic work as a
64 shadow for a primitive procedure. If the primitive procedure
65 can't dispatch on its arguments, control is left over to the
66 generic. Normal wrong type arg errors will be generated until the
67 user has hung the first method on the primitive.
69 * snarf.h (SCM_GPROC, SCM_GPROC1): New macros.
71 * procs.c, procs.h (scm_subr_p): New function (used internally).
73 * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function.
75 * objects.c, objects.h (scm_primitive_generic): New class.
77 * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros.
79 * print.c (scm_iprin1): Print primitive-generics.
81 * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1,
82 SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros.
84 * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta -->
85 SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point
86 primitives). NOTE: This means that it is now *required* to use
87 SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an
88 obscured representation that will be removed in the future anyway,
89 so backward compatibility is no problem here).
91 * numbers.c: Converted most numeric primitives (all but bit
92 comparison operations and bit operations) to dispatch on generic
96 Better support for applying generic functions.
98 * eval.c, eval.h (scm_eval_body): New function.
100 * objects.c (scm_call_generic_0, scm_call_generic_1,
101 scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New
105 Optimization of the generic function dispatch mechanism.
107 * eval.c (SCM_CEVAL): Apply the cmethod directly after having
108 called scm_memoize_method instead of doing a second lookup.
110 * objects.h (scm_memoize_method): Now returns the memoized cmethod.
115 * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of
116 scm_sysintern so that the binding connected with the subr name
117 isn't cleared when we give set = 0.
120 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
122 More transparent handling of ports with print states.
124 * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT,
125 SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob
126 instead of a pair of a port and a print state. We'll need to cons
127 once extra in scm_printer_apply but the type system will be
128 cleaner, it will mix better with GOOPS, and, it will be even more
129 transparent to the user.
131 * print.c (scm_get_print_state): New procedure: Given an output
132 port, return the print state associated to it in the current print
133 chain, if one exists;
134 (scm_port_with_print_state): New procedure: Associate a
135 print-state with a port.
136 (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P;
137 (scm_printer_apply): Wrap port and pstate as a smob;
138 (print_state_printer): Removed.
140 * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports.
142 * eval.c (scm_init_eval): Use scm_make_smob_type instead of
145 * ports.c (scm_output_port_p): Bugfix: Coerce output port before
146 testing (otherwise the port-print-state trick won't be transparent
147 to the user; one example where this caused problems was in the
148 (ice-9 format) module).
150 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
152 * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return
153 SCM_UNSPECIFIED instead of the set value.
155 1999-08-20 James Blandy <jimb@mule.m17n.org>
157 * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH.
159 * ports.h (enum scm_port_rw_active): New enum, containing
160 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
161 zero). The debugger knows about enums, but doesn't know about
163 (typedef scm_port): Declare rw_active member to be an enum
165 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
167 * ports.c (scm_add_to_port_table): Same.
168 * strports.c (st_flush, st_end_input): Same.
170 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
171 scm_must_realloc, and scm_done_malloc as appropriate.
173 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
175 * sort.c (quicksort): Added condition to protect the algorithm
176 from crashing the interpreter if the less predicate is buggy.
178 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
180 * fports.c (fport_write): fix line-buffering mode again.
181 (scm_open_file): recognise 'l' for line-buffering.
182 (scm_setvbuf): recognise _IOLBF for line-buffering.
184 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
186 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
189 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
192 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
194 * fports.c (fport_write): use memcpy instead of strncpy, in case
195 the data contains NUL.
197 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
199 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
201 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
202 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
203 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
204 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
205 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
206 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
207 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
208 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
209 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
210 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
211 scm_sym_ as prefix for symbols.
213 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
215 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
216 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
217 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
218 scm_sym_atcall_cc): Made global.
220 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
222 * eval.c (scm_sym_args): Made global.
224 * objects.c (scm_set_object_procedure_x): Disallow setting of
225 procedures for pure generic functions.
227 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
229 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
230 Scheme name from lseek to seek, but lseek was added recently so
231 it shouldn't be a big problem.
232 * ports.c, gdbint.c, ioext.c: changed callers.
234 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
236 * fports.c (fport_input_waiting): if select is used, return 1
237 instead of whatever FD_ISSET expands to. maybe it will be useful
238 to interpret the value from the input_waiting ptob procedure as a
239 lower bound on the number of bytes available.
241 * Mikael asked for a few names to be changed...
243 * ports.c (scm_make_port_type): take the write procedure as the
244 second argument instead of the flush procedure.
245 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
246 fflush -> flush, read_flush -> end_input, fclose -> close,
247 fill_buffer -> fill_input, ftruncate -> truncate,
248 input_waiting_p -> input_waiting.
250 * ports.c (end_input_void_port): was read_flush_void_port.
251 (scm_set_port_end_input): was scm_set_port_flush_input.
252 (scm_set_port_flush): was scm_set_port_write.
253 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
254 (scm_end_input): was scm_read_flush.
255 (scm_fill_input): was scm_fill_buffer.
256 (scm_flush): was scm_fflush.
257 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
258 (fport_end_input): was local_read_flush.
259 (fport_flush): was local_fflush.
260 (fport_close): was local_fclose.
261 (fport_truncate): was local_ftruncate.
262 (fport_seek): was local_seek.
263 (fport_free): was local_free.
264 (fport_fill_input): was fport_fill_buffer.
265 * strports.c (st_end_input): was st_read_flush.
266 (st_truncate): was st_ftruncate.
267 * vports.c: (sf_flush): was sfflush.
268 (sf_close): was sfclose.
269 (sf_fill_input): was sf_fill_buffer.
271 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
274 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
276 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
277 forms now contain the expressions to be dispatched upon instead of
278 depending on a surrounding lambda or let; Generic function
279 dispatch has been optimized; `apply' on a generic function now
280 works a little bit strangely. It uses a trick so that the type
281 dispatch code in SCM_CEVAL can be reused.
283 * objects.h, objects.c (scm_apply_generic_env): Added (used by
285 (scm_operator_p): Added.
286 (scm_sym_atdispatch): Added.
287 (scm_set_object_procedure_x): Modified to handle the new style
289 (scm_object_procedures): New debugging procedure.
291 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
293 * eval.c, eval.h (scm_sym_args): Added.
295 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
297 * feature.c, feature.h (scm_c_run_hook): Added.
299 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
300 cdrxnoap and loopnoap instead of begin and loop.
302 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
304 * ports.c (scm_putc, scm_puts),
305 * unif.c (scm_uniform_array_write): use scm_lfwrite.
306 * ports.c (scm_putc): change type of first argument from int to char.
308 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
310 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
311 SCM_IM_HASH_DISPATCH.
313 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
314 (scm_si_redfined, scm_si_hashsets): Moved.
316 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
317 flag which combines type and status info so that the class
318 redefinition protocol has zero cost during normal execution.
320 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
322 * ports.h (scm_ptob_descriptor): include a write procedure again.
323 it's more efficient for unbuffered fports (e.g., sockets.)
325 * ports.c (scm_puts): use ptob->write.
326 * vports.c (scm_make_sfptob): set write proc in ptob.
327 * strports.c (scm_make_stptob): set write proc in ptob.
328 * ports.c (write_void_port): new procedure.
329 * vports.c (sf_write): new procedure.
330 * ports.c (scm_lfwrite): use ptob->write.
331 * strports.c (st_write): new procedure.
332 * fports.c (fport_write): new procedure.
333 (scm_make_fptob): set write in ptob to fport_write.
334 * ports.h: prototype for scm_set_port_write.
335 * ports.c (scm_make_port_type): initialise ptob write procedure.
336 (scm_set_port_write): new proc.
338 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
340 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
341 until we've verified that it is actually a port. (Thanks to
344 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
346 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
347 code, particularly an unnecessary test (len != size, where len ==
348 size). (Was this leftovers from debugging code, or have I missed
351 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
352 size. (Thanks to James Dean Palmer.)
354 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
355 (Thanks to Lorentey Karoly.)
357 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
359 * eval.c (scm_m_expand_body): Use scm_cons_source.
361 * struct.c (scm_print_struct): Use vtable name.
363 * print.c (scm_init_print): Set name of print state type.
365 * stacks.c (scm_init_stacks): Set name of stack type.
367 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
369 * eval.c (SCM_CEVAL): Removed old implementation of internal
372 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
374 * debug.c, debug.h (scm_reverse_lookup): Added.
375 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
376 internal procedure definitions; Don't use scm_i_inner_name.
378 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
381 * eval.h: Added prototypes for multi language support functions.
383 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
384 improper lists in the low-level representation, since that will
385 cause a begin to be prepended at macro expansion.
387 * eval.c (scm_cons_source): Version of cons which copies source
388 properties from an existing cell.
389 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
391 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
392 procedure source before calling scm_unmemocopy instead of faking
395 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
397 Ported `internal defines' fix from SCM. Original ChangeLog entry:
399 1998-07-09 Radey Shouman <radey@colorage.com>
401 * eval.c (ceval_1): Modifications to allow rewriting of interal
402 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
403 body of which it is the CAR is macro expanded by m_expand_body,
404 which rewrites internal DEFINE.
406 (m_expand_body): Added.
408 (m_macroexp1): Added argument to control error checking:
409 m_expand_body may speculatively expand forms in the wrong
410 environments. Made argument number checks conditional on
413 (m_body): Added, error checks bodies and inserts the ISYM tokens.
415 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
418 (m_cond): (m_case): (m_quote): Modified to avoid destructively
419 changing their argument forms. Since m_expand_body
420 speculatively macro expands forms the process must be
423 (m_ident_eqp): Fixed to use proper environment.
425 (renamed_ident): Added DEFER_INTS_EGC.
427 Added prototypes for static functions.
433 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
434 is false, do not produce an error for unbound variables, return a
435 pointer to cell_undef instead.
437 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
441 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
442 destructively changing their argument forms. Since m_expand_body
443 speculatively macro expands forms the process must be reversible.
445 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
446 SCM_IM_LET introduced by named lets.
448 (scm_m_letstar): Use scm_m_body instead of bodycheck.
450 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
451 scm_letrec. scm_letrec1 does not check for a null binding and
452 takes an additional argument to specify the ISYM of the body. Use
453 scm_m_body instead of bodycheck.
455 (scm_m_let): Use scm_m_body instead of bodycheck.
457 (scm_m_expand_body, scm_macroexp): New.
459 (unmemocopy): Account for ISYMs introduced by scm_m_body.
461 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
462 check=1. Throw error for internal defined that have not been
463 rewritten by scm_m_expand_body.
465 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
466 Removed prototype for SCM_APPLY.
468 * tags.h: Added extern declaration of scm_isymnames.
470 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
472 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
474 * lang.c: New file: Beginning of multi-language support.
476 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
478 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
479 (scm_dynamic_wind): Added argument checking for the after guard so
480 that we don't add garbage on the dynwind chain.
481 (scm_swap_bindings): Added.
483 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
484 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
485 (scm_isymnames): New isyms for multi-language support.
487 * eval.c (scm_nil, scm_t): New symbols.
488 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
489 forms for multi-language support.
491 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
493 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
495 Renamed functions in the random function library interface
496 from scm_i_XXX --> scm_c_XXX.
498 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
500 * ports.c (scm_putc): fix line-buffering.
502 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
504 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
505 scm_set_ptob_XXX --> scm_set_port_XXX.
507 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
509 * ports.c, ports.h (scm_make_port_type): New interface for
510 creation of port types (replaces scm_newptob). Just as for the
511 smobs, we need to separate the internal representation of smob
512 types from the interface, so that we easily can add new fields and
513 rearrange things without caring about backward compatibility.
514 This change was forced by the need in GOOPS to create classes
515 representing port types.
516 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
517 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
518 scm_set_ptob_seek, scm_set_ptob_truncate,
519 scm_set_ptob_input_waiting_p): New setters.
520 (scm_newptob): Rewritten to use scm_make_port_type. For backward
522 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
523 (scm_prinport): Removed.
524 (scm_port_print): Added.
525 (scm_print_port_mode): Added.
526 (void_port_ptob, print_void_port, close_void_port, noop0):
527 Removed. Removed #include "genio.h" Added #include "objects.h",
530 * fports.c (prinfport): Moved code from ports.c.
532 (scm_fptob): Removed. Instead use new interface.
533 (scm_make_fptob): Added. (Need to create basic ports in a
534 specific order in ports.c.)

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

603 * scmconfig.h.in: Regenerated.
605 * stime.c (ftime): Delete declaration for this function --- let
606 the system supply it.
608 Cleanups from John Bley.
610 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
612 * gsubr.c: Don't include "gsubr.h" twice.
614 Cleanups for compilation on Irix 6, from David Kaelbling.
616 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to

618 (scm_regexp_exec): Don't forget to pass the `rx' argument to
619 scm_regexp_error_msg.
621 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
622 int. That way, if we get a warning on this line, it's more likely
623 that we're really missing bits we care about.
625 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
628 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
629 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
630 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
631 cast at all is more appropriate in every case. At the moment, we
632 assume everywhere that SCM is an integral type anyway.

643 fports.c (fport_fill_buffer): implement the interface change.
645 * ports.c (scm_fill_buffer): interface change: no longer increments

669 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
670 it's greater and reset read_buf_size.
671 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
672 to be maintained for output ports too (it holds the written
673 part of the string, while write_buf may have unwritten buffer
675 (st_truncate): rewritten.
676 (top of file): added a few notes.
678 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
680 Patch from Greg Badros:
681 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
682 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
683 (function pointer) argument to scm_make_gsubr and scm_make_subr
684 calls. This avoids warnings in C++ programs using guile-snarf.
686 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
688 * strports.c (st_grow_port): set pt->read_pos. set
689 pt->read_buf_size one less than pt->write_buf_size if there's
690 an unwritten char at the end of the string. similarly for
692 (st_resize_port): renamed from st_grow_port.
693 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.

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

1023 string, so seek and ftruncate can be used.
1025 gdbint.c: adjust string port usage.
1027 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
1029 * ports.h (scm_ptobfuns): add a read_flush procedure which is the

1068 waiting for input caused an EINTR error from read.
1070 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
1072 * ports.h (struct scm_port_table): make all the char members
1073 unsigned, so they convert to int without becoming negative if large.
1075 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
1077 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
1078 with threads enabled. rename this procedure to
1079 fport_wait_for_input and take a port instead of a fdes.
1080 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
1082 * readline.c (scm_readline): Applied a patch from Greg Harvey to
1083 get readline support working again: use fdopen to get FILE objects.
1085 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
1087 * gc.c (scm_init_storage): install an atexit proc to flush the
1089 (cleanup): the new proc. it sets a global variable which can be
1090 checked by the ptob flush procs to avoid trying to throw
1091 exceptions during exit. not very pleasant but it seems more reliable.
1092 * fports.c (local_fflush): check terminating variable and if set
1093 don't throw exception.
1094 * CHECKME: that the atexit proc is installed if unexec used.
1096 * throw.c (scm_handle_by_message): don't flush all ports here.
1097 it still causes bus errors.
1099 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
1100 and move to ioext.c.
1102 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.

1105 ptob entry if needed.
1107 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
1108 ptob initialisers. use it in char-ready
1110 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
1112 * vports.c (sfflush): modified to write a char (since softports
1113 currently use shortbuf.)
1115 * fports.c (scm_standard_stream_to_port): moved to init.c and
1118 * init.c (scm_init_standard_ports): make stdout and stderr
1119 unbuffered if connected to a terminal. with stdio they
1120 were line-buffered by default.
1122 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
1125 * ports.h (scm_ptobfuns): change fflush return to void.
1126 change flush proc definitions.

1129 buffer instead of port stream.
1130 (st_flush): new proc.
1132 * ports.h (struct scm_port_table): added write_end member,
1133 as an optimisation. set it where write_buf_size is set.
1135 * ports.h (struct scm_port_table): change stream from void *
1136 back to SCM. SCM presumably must be large enough to hold a
1137 pointer (and probably vice versa but who knows.)
1138 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
1140 (scm_puts): rewritten
1141 * fports.c (local_ffwrite, local_fputs): removed.

1157 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
1158 use ptob for seek. take ptob instead of fport arg.
1160 * ports.h (struct scm_port_table): new member write_needs_seek,
1161 replaces reading member in fport struct.
1163 * vports.c (sfgetc): store the getted char into the buffer.
1164 rename to sf_fill_buffer and install it for fill-buffer in ptob.
1165 the Scheme interface is still a procedure that gets a char.
1166 (scm_make_soft_port): set up the port buffer (shortbuf).
1168 * fports.c (local_fgetc, local_fgets): deleted.
1169 * strports.c (stgetc): likewise.

1175 put just the string into the stream, not cons (pos stream).
1176 (stfill_buffer): new proc.
1178 * ports.h: fport buffer moved into port table: to be
1179 used for all port types.

1322 do it where it's needed in the port smobs.
1323 * filesys.c (scm_input_waiting_p): moved to fports.c, stdio
1324 buffer support removed. take SCM arg, not FILE *.
1325 * filesys.h: prototype moved too.

1372 1999-05-09 Jim Blandy <jimb@savonarola.red-bean.com>
1374 * strop.c (scm_string_capitalize_x): Use the SCM object `s' in
1375 error messages, not the uninitialized string `str'. Love that
1378 * strop.c (scm_substring_move_x): New function, which can handle
1379 arbitrary overlapping substrings.
1380 (substring-move-left!, substring-move-right!): These are
1381 now just synonyms for substring-move!.
1382 * strop.h (scm_substring_move_x): New prototype.
1383 (scm_substring_move_left_x, scm_substring_move_right_x):
1384 #define these as synonyms for scm_substring_move_x.

1391 functions; capitalize the first letter of each word in the
1392 argument string, and downcase the rest.
1393 (scm_string_ci_to_symbol): string->symbol, such that the same

1456 * numbers.c (isfinite): Define this macro if not defined: Return a
1457 non-zero value if X is finite. (From ISO C 9x standard.)
1458 (scm_inexact_to_exact): Bugfix: Don't pass NaNs to scm_dbl2big.
1459 (Thanks to Jon Trowbridge and Greg Harvey.)
1461 1999-03-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1499 * error.c (scm_wta): Pass SCM_LIST1 (arg) instead of SCM_EOL to
1500 scm_misc_error when pos is a string. This allows for dispatching
1501 arbitrary error messages with one argument via SCM_ASSERT:

1510 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1512 Most of this batch of changes is about how to deal with extended
1513 types when an object system is loaded into Guile. A nice object
1514 system is capable of representing Guile's types as class objects.
1516 For example, we want a regular expression to be of class <regex>.
1517 But regular expressions are smobs which aren't under direct
1518 control of the object system, so there has to be some mechanism
1519 which informs the object system that a new class should be created
1520 which can represent the smob type. I call this a "wrapper class".
1522 * objects.c: #include "smob.h";
1523 (scm_class_keyword): Removed. (Class is automatically created by
1525 (scm_smob_class): Array of smob classes indexed by smobnum.
1526 (scm_make_extended_class): "Plugin" function pointer for creation
1527 of wrapper classes for smob and struct types.
1528 (scm_class_of): Handle compiled closures. (Currently regarded as
1530 Use scm_smob_class to handle smob types;
1531 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1532 through scm_smob_class;
1535 * smob.c (scm_newsmob): Also create a wrapper class if
1536 scm_smob_class has been initialized.
1538 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1539 type code and smobnum.
1541 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1542 (scm_struct_table): Weak key table with auxilliary information for
1543 struct types. Currently used for names and wrapper classes.
1544 (scm_struct_ihashq): Hash function for structs.
1545 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1546 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1547 for accessing names of vtables. The record implementation in
1548 boot-9.scm currently uses the setter to record the name of record
1549 types. When the object system is initialized, it can use this
1550 information to create wrapper classes with suitable names.
1551 (scm_init_struct): Allocate scm_struct_table.
1552 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1553 (struct tags are a finite resource and we might want to restrict
1554 the use of tags to vtables only. E.g., Goops only uses tags for
1556 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1558 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1561 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1562 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1563 Used for access of struct table entries.
1565 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1566 (scm_hash_fold): New procedure. Used to process all entries in a
1567 hash table (in no particular order).
1569 Argh! For the umpteenth time I got compilation errors because of
1570 the "intuitive" name `kw'. This has to have an end:
1572 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1573 "kw" --> "keywords" everywhere.
1574 (I doubt that this will cause big compatibility problems since the
1575 application interface is unaffected.)
1577 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.

1726 SYMB now point to const.
1728 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1730 * print.c (scm_iprin1): Use scm_procedure_name instead of
1731 scm_procedure_property for compiled closures.
1733 * tags.h (scm_tc7_pws): New procedure type. Four representations
1734 for procedure-with-setters were considered before selecting this
1737 1. A closure where the CODE and ENV slots are used to represent
1738 the getter and a new SETTER slot is used for the setter. The
1739 original getter is stored as a `getter' procedure property. For
1740 closure getters, the CODE and ENV slots contains a copy of the
1741 getter's CODE and ENV slots. For subr getters, the CODE contains
1744 2. A compiled closure with a call to the getter in the cclo
1745 procedure. The getter and setter are stored in slots 1 and 2.
1747 3. An entity (i.e. a struct with an associated procedure) with a
1748 call to the getter in the entity procedure and the setter stored
1749 in slot 0. The original getter is stored in slot 1.
1751 4. A new primitive procedure type supported in the evaluator. The
1752 getter and setter are stored in a GETTER and SETTER slot. A call
1753 to this procedure type results in a retrieval of the getter and a
1754 jump back to the correct eval dispatcher.
1756 Representation 4 was selected because of efficiency and
1759 Rep 1 has the advantage that there is zero penalty for closure
1760 getters, but primitive getters will get considerable overhead
1761 because the procedure-with-getter will be a closure which calls
1764 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1765 <procedure-with-setter>, but together with rep 2 it suffers from a
1766 three level dispatch for non-GOOPS getters:
1768 cclo/struct --> dispatch proc --> getter
1770 This is because the dispatch procedure must take an extra initial
1771 argument (cclo for rep 2, struct for rep 3).
1773 Rep 4 has the single disadvantage that it uses up one tc7 type
1774 code, but the plan for uniform vectors will very likely free tc7
1775 codes, so this is probably no big problem. Also note that the
1776 GETTER and SETTER slots can live directly on the heap, using the
1777 new four-word cells.
1779 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,

1864 understand, when I ran automake in the top level directory. This
1865 may be contamination by Cygnus internal releases. If you re-run

2026 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
2027 scm_logbit_p): Do the computation in ulongs. This is not as nice
2028 as doing it in bignums, but at least it's good enough for
2029 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
2031 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
2032 subexpressions. (Thanks to Charbel Jacquin.)

2044 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2046 * modules.c, modules.h: New files: C interface to modules. (This
2047 is necessary in order to interface the object system to Guile
2048 properly. The guts of these modules will be replaced by the new
2049 module system in the future.)

2073 * eval.c (SCM_CEVAL): Allow structs implanted in code.
2074 Previously, structs implanted in code were interpreted as forms
2075 the operator of which was a gloc. We solve this by checking for
2076 the zero in the emulated vcell in the struct vtable. Since
2077 implanted structs always will look like forms with a gloc
2078 operator, execution will only be slowed down by maximally one
2079 extra test-and-branch per application.
2081 * evalext.c (scm_definedp): Removed check for isyms; Added a
2082 second optional argument: It is now possible to supply an
2083 evaluation environment in which to look for the symbol.
2085 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2087 * readline.c (scm_init_readline): Set
2088 rl_basic_word_break_characters. (Thanks to Ian Grant.)
2090 * coop.c (coop_condition_variable_wait): Removed
2091 (coop_condition_variable_wait_mutex): Folded logic of
2092 coop_mutex_unlock into coop_condition_variable_wait_mutex to
2093 prevent condvar signal lossage. Previously, another thread could
2094 start to run after unlocking the mutex but before putting the
2095 current thread on the wait queue. If that thread then would
2096 signal the first, the signal would be lost. (Thanks to Christian
2099 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2101 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
2104 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2106 * objects.c (scm_i_make_class_object): Renamed from
2107 make_class_object; exported; error checking moved to
2108 scm_make_class_object and scm_make_subclass_object.
2109 (scm_make_class_object, scm_make_subclass_object): Use
2110 scm_i_make_class_object.
2111 (scm_make_subclass_object): Let the subclass have same metaclass
2114 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2116 * debug.c (scm_debug_options): Bugfix: Set the value of
2117 scm_stack_checking_enabled_p after setting debug options;
2118 #include "stackchk.h". (Thanks to Richard Polton.)
2120 1998-11-13 Radey Shouman <rshouman@metro2000.com>
2122 * unif.c (scm_array_contents): removed unnecessary test for 0
2125 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2127 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
2128 Replaced by macro `collect' in boot-9.scm.
2130 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2132 * eval.c (scm_copy_tree): Copy source properties if existent.
2134 * debug.c (scm_start_stack): Copy source when evaluating. (If we
2135 don't, we may end up passing memoized source to a transformer.)
2137 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2139 * stack.c (get_applybody): Help function which lookups the first
2140 body form of the apply closure.
2141 (read_frames): Prevent the source of the first form of the apply
2142 closure from being recorded. This would only be confusing.
2144 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
2145 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
2147 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
2149 * stacks.c (read_frame): Bugfix: Removed lingering `else'
2151 (read_frames): Use SCM_MACROEXPP.
2153 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2155 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
2156 don't contain interesting information since all arguments are
2157 present in the frame which applies the compiled closure anyway.);
2158 Skip the transformer application frames.
2160 * print.c (scm_iprin1): Print gsubrs as primitives.
2162 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2164 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
2166 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
2167 that we can identify these in a backtrace. (This change doesn't
2168 introduce any significant speed penalty.)
2170 * eval.c: Added note about `serial-map' using scm_map.
2172 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2173 readline options. They should reside in their own options array.
2175 * readline.c, readline.h (scm_readline_options,
2176 scm_readline_opts): Moved readline options here.
2178 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2180 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2181 SCM_ROCHARS instead of SCM_CHARS.
2183 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2184 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2186 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2188 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2189 This is quite important since the latter clears the
2190 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2191 every single character read...
2193 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2195 * print.c (scm_iprin1): Removed suspect looking (and indeed
2196 malevolent) semicolon after test for user supplied closure print
2197 procedure. (Thanks to Telford Tendys.)
2199 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2200 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2201 starting to search the list. Removed call to sloppy_mem_check.
2203 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2204 procedures: Same as scm_delq_x et al, but delete maximally one
2207 * options.c (scm_options, scm_init_options): GC-protect option
2208 values of type SCM. (Thanks to Telford Tendys.)
2210 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2212 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2213 make sure that there always is a "real" scm_lookupcar.
2215 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2217 * read.c, read.h (scm_read_opts): New read options
2218 "history-length" and "history-file".
2219 (scm_read_options): Stifle history to history length.
2221 * readline.c (scm_read_history, scm_write_history): New procedures.
2223 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2225 * eval.h (scm_macro_eval_x): Removed declaration.
2227 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2228 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2229 Renamed and made global.
2231 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2232 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2234 * evalext.c, evalext.h: New files. Contain non-R5RS things
2235 having to do with evaluation.
2237 * evalext.c (scm_serial_map): New procedure: Version of `map'
2238 which guarantees that the procedure is applied to the lists in
2240 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2241 returns a list of the results of the body forms instead of the
2242 result of the last body form.
2243 (scm_definedp, scm_m_undefine): Moved from eval.c
2245 * evalext.h (scm_m_sequence_to_list): Added declaration.
2247 * macros.c, macros.h: New files.
2248 (scm_procedure_to_syntax, scm_procedure_to_macro,
2249 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2250 scm_macro_name, scm_macro_transformer): Moved from eval.c
2251 (scm_make_synt): Moved from eval.c
2253 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2255 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2258 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2260 * debug.c, print.c: Added #include "macros.h".
2262 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2264 This change adds the ability to use `unread-char' multiple times
2265 without interspersed reads and adds the new procedure
2266 `unread-string'. The change is optimized for the common case of
2267 unreading a single character. This is also the reason behind the
2268 choice to store characters in the port itself: in most cases no
2269 extra malloc is required.
2271 The amount of code in some macros in ports.h has been increased to
2272 the extent that they would fit better as C functions, but, since
2273 this code belongs to the port representation, such functions
2274 should be placed in ports.c which would cause calls back and forth
2275 between ports.c and genio.c. That is not good for performance.
2276 Also, keeping them as macros allows the compiler to do some
2277 optimizations which are needed to make the current interface
2278 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2280 One benchmark (Guile startup time) indicates an increase of
2281 loading speed of 1%. Another (reading (using `read') boot-9.scm
2282 10 times) shows no change in performance.
2284 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2285 made to find a beautiful solution.)
2287 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2288 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2289 character. (SCM_CLRDY clears all.)
2290 (SCM_N_READY_CHARS): New macro: Returns number of unread
2291 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2292 (struct scm_port_table): New fields: `entry' contains port table
2293 index, `cp' points to last unread char, `cbuf' is the buffer for
2294 unread chars, `cbufend' points after end of the character buffer.
2296 * ports.h, ports.c (scm_unread_string): New procedure.
2297 (scm_grow_port_cbuf): New function.
2299 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2301 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2302 to read unread characters. Use SCM_TRY_CLRDY instead of
2305 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2307 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2309 * genio.c, genio.h (scm_ungets): New function.
2311 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2314 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2316 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2317 declarations. (Thanks to Russ McManus.)
2319 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2321 * numbers.c (num2long): As a software archeologist, I'm proud of
2322 this finding! :) Preliminary dating suggests an almost 4 year old
2323 remnant from the SCM ancestor. The sample has been removed from
2324 the finding site and is now safely stored in the repository.
2326 * numbers.h: Removed prototype for num2long.
2328 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2330 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2331 array as second arg.
2332 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2333 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2334 * gh.h: Updated and added prototypes.
2336 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2338 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2340 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2342 * guile-snarf.in: Never generate an empty file. (Thanks to
2345 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2346 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2347 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2348 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2349 gh_new_procedure5_0): Specify argument types, to appease C++
2350 compilers. (Thanks to Brad Bowman.)
2352 Bug reports from Russ McManus:
2353 * guile-snarf.in: If the CPP environment variable is set, use that
2354 as the C preprocessor, instead of the preprocessor autoconf
2356 * snarf.h (SCM_PROC): Cast the function pointer passed to
2357 scm_make_gsubr, to satisfy C++.
2359 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2360 Use the handler passed, instead of ignoring it and using
2361 gh_standard_handler. (Thanks to Etienne Bernard.)
2363 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2365 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2368 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>
2370 * __scm.h, alist.c, async.c, async.h, backtrace.h, chars.c,

2388 * script.c (scm_compile_shell_switches): Define
2389 use-emacs-interface in the root module, so the repl code can see
2390 it. See today's change to top-repl in ice-9/boot-9.scm.
2392 * filesys.c (set_element, get_element): Make sure that `element'
2393 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2394 Boekemeier and Jorgen "forcer" Schaefer.)
2396 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2398 * chars.c (scm_charnames): In ASCII character name table, make
2399 newlines print as #\newline by default, not #\nl.
2401 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2402 alphabetical order. Oh thrills. But it helps me know how far
2403 along in the compilation I am.
2404 * Makefile.in: Regenerated.
2406 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2408 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2409 #bytes(...) to #y(...), and syntax for short vectors from
2410 #short(...) to #h(...). This may seem nutty, but, like the other
2411 uniform vectors, byte vectors and short vectors want to have the
2412 same print and read syntax (and, more basic, want to have read
2413 syntax!). Changing the read syntax to use multiple characters
2414 after the hash sign breaks with the conventions used in R5RS and
2415 the conventions used for the other uniform vectors. It also
2416 introduces complexity in the current reader, both on the C and
2417 Scheme levels. (The Right solution is probably to change the
2418 syntax and prototypes for uniform vectors entirely.)
2420 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2422 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2423 (Thanks to Jorgen "forcer" Schaefer.)
2424 * ports.h (SCM_NOFTELL): New flag.
2425 * fports.c (local_fgets): If it's set, use the generic fgets.
2426 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2428 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2430 * script.c (scm_compile_shell_switches): Add handling of -q switch
2431 (inhibit loading of user init file).
2432 (scm_shell_usage): Add usage text for -q switch.
2433 (scm_compile_shell_switches): Always load user init file first if
2434 it is loaded at all.
2436 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2438 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2439 and is now broken under NetBSD. I can't fathom what it's trying
2440 to do, so I've replaced it with something that I do understand,
2441 which seems to work, and which isn't broken on NetBSD. "Progress?
2442 You Decide." (Thanks to Perry Metzger.)
2444 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2445 signed/unsigned comparison.
2447 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2449 Warning fixes from Greg Harvey:
2450 * unif.c (scm_array_set_x): initializer for pos
2451 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2452 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2453 initializers for field_type, since EGCS so desparately wants to
2455 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2456 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2457 when GUILE_DEBUG is defined.
2458 * dynwind.h (scm_wind_chain): Same.
2459 * ports.h (scm_pt_size, scm_pt_member): Same.
2460 * print.h (scm_current_pstate): Same.
2461 * procs.h (scm_make_cclo): Same.
2463 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2465 Handle short and long long uniform arrays properly. (Thanks to
2467 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2468 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2469 scm_tc7_llvect (long long vectors).
2471 Change the way libguile and boot-9.scm are timestamped, to try to
2472 get rid of these spurious mismatch warnings. Now both
2473 libguile/versiondat.h and ice-9/version.scm are generated directly
2474 by the configuration process, rather than having version.scm
2475 generated directly, and libguile/versiondat.h generated by the
2476 Makefile, which is generated by configure. It seems that
2477 sometimes the Makefile would change, but versiondat.h depends on
2478 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2479 * Makefile.am (versiondat.h): Target removed; this is generated
2480 directly by the configure script now.
2481 (BUILT_SOURCES): Remove versiondat.h.
2482 * versiondat.h.in: New file, transformed by the configure script
2484 * Makefile.in: Regenerated.
2486 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2487 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2488 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2489 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2490 if we want to use them in a header file some day, we can. (Thanks
2491 to Michael Livshin.)
2493 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2494 SCM numbers, so we won't have rollover problems; the range of a
2495 signed long in milliseconds is about 25 days. (Thanks to Karl
2498 Don't redefine sleep and usleep; fix this problem now.
2499 * coop.c (sleep, usleep): Remove declarations; we don't use or
2500 redefine these any more.
2501 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2502 job of usleep and sleep in a thread-friendly way. We can use
2503 these in the rest of Guile. Define versions for systems both with
2504 and without iselect.
2505 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2506 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2507 we're just using it, not redefining it, we can use a K&R style
2509 (sleep): Declare this, too, if the system hasn't.
2510 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2511 scm_uthread_sleep if they're available; otherwise, just call the
2513 * scmconfig.h.in: Regenerated.
2515 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2517 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2519 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2521 * threads.c: Doc fix.
2523 The argument type of usleep varies from system to system,
2524 as does the return type. We really shouldn't be redefining usleep
2525 at all, but I don't have time to clean that up before the 1.3.
2526 release. It's on the schedule for afterwards. (Thanks to Julian
2528 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2530 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2531 * scmconfig.h: Regenerated.
2533 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2534 right way to handle system variation. Autoconf's approach is the
2536 * simpos.h (scm_software_type): Declaration deleted.
2538 * script.c (scm_find_executable): Don't test if unix is #defined
2539 here; first, NetBSD doesn't #define it, and second, it's the wrong
2540 way to go about these things. (Thanks to Perry Metzger.)
2541 (dld_find_executable): Delete this MSDOS support code. This isn't
2542 the way we want to support this; it needs to be rethunk at a
2545 * genio.c (scm_do_read_line): Don't just politely check that the
2546 line was either non-empty or EOF. Abort if it's empty and not
2549 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2551 * scmconfig.h.in: Regenerated.
2553 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2556 * genio.c (scm_do_read_line): Count lines correctly when the file
2557 doesn't end in a newline.
2559 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2561 * genio.c (scm_do_read_line): Maintain the line count correctly.
2562 (Thanks to Harvey J. Stein and Greg Harvey.)
2564 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2567 * numbers.c (big2str): Protect t from garbage collection until
2568 we're done. (Thanks to Gary Houston.)
2570 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2572 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2574 * Makefile.in: Regenerated.
2576 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2577 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2580 Do magic to mix reads and writes on stdio FILE-based ports.
2581 (Thanks to Christian Lynbech.)
2582 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2584 (pre_read, pre_write): New functions.
2585 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2586 local_fputs): Call them.
2587 (local_fflush): Mark the port as ready for reading and writing.
2588 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2589 flags on new port objects. This might not be accurate --- who
2590 knows what state the FILE * is in when we get it --- but it won't
2591 do extraneous calls to fflush or fseek, so it's no worse than the
2592 behavior before this change.
2593 * ports.h: Add comment.
2595 Centralize the creation of port objects based on stdio FILE * in
2596 fports.c; don't just throw them together anywhere.
2597 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2598 what the rest of Guile wants. Don't set the revealed count;
2599 that's only appropriate for stdin, stdout, stderr.
2600 (scm_standard_stream_to_port): This function does set the revealed
2602 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2603 not scm_stdio_to_port.
2604 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2605 * fports.c (scm_open_file): Same.
2606 * posix.c (scm_pipe): Same.
2607 * socket.c (scm_sock_fd_to_port): Same.
2608 * ioext.c (scm_fdopen): Same.
2609 (scm_freopen): Moved from here to...
2610 * fports.c (scm_freopen): ... here. This is really something that
2611 munges the internals of an fport, so it should go here.
2612 * fports.h (scm_stdio_to_port): Adjust prototype.
2613 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2614 * ioext.h (scm_freopen): Prototype removed.
2616 * filesys.c (set_element, get_element): This can work on both pipe
2617 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2620 * scmconfig.h.in: Regenerated.
2622 Change the definition of the functions in scm_ptobfuns so that
2623 they get passed the port object, not the port's stream.
2624 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2625 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2626 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2627 Pass the port itself to the scm_ptobs function.
2628 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2629 scm_generic_fgets): Same.
2630 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2631 getc_void_port, fgets_void_port, close_void_port): Just change the
2632 argument names; these functions don't really do anything.
2633 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2634 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2635 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2636 Also, use prototyped definitions, and get rid of the extra
2638 (scm_fptob, scm_pipob): We don't need casts here any more.
2639 * strports.c (prinstpt): Use prototype declarations.
2640 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2641 and use SCM_STREAM to get the string info. Also, use prototyped
2642 definitions, and get rid of the extra declarations.
2643 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2646 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2647 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2649 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2650 scm_fgets, for consistency.
2651 (scm_fptop, scm_pipob): References updated.
2653 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2655 Include the source location in error messages for scripts.
2656 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2657 stack is still there when we catch the error.
2658 * throw.c (handler_message): If we are handling an error with a
2659 message, then put together the proper arguments and call
2660 scm_display_error, instead of scm_display_error_message. That
2661 displays source location, if it can find it.
2663 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2665 * gc.c (scm_unprotect_object): Change this so that calls to
2666 scm_protect_object and scm_unprotect_object nest properly.
2667 (scm_protect_object): Doc fixes.
2669 * strings.c (scm_string_set_x): Require the argument to be a
2670 writable string, not a substring or a symbol.
2671 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2672 (Thanks to John Redford and Charbel Jacquin.)
2674 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2676 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2678 * eval.c (safe_setjmp): Remove this misunderstanding.
2679 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2682 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2684 * libguile.h: Mark these as C declarations, for compilation by C++
2687 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2688 __cplusplus clause. I seriously doubt this ever worked the way
2689 the author seems to have intended.
2691 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2693 Utterly needless cleanups to hopelessly messy code.
2694 * ports.c: Doc fixes.
2695 (scm_fflush): Moved to ...
2696 * genio.c (scm_fflush): ... here, amongst all the other port
2697 method invocation functions.
2698 * genio.h, ports.h: The prototype moves too.
2700 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2702 * backtrace.c (display_error_body): The current frame does not
2703 always have a parent frame; consider a function called directly
2704 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2707 * alloca.c (alloca): Undo yesterday's changes, and simply call
2708 malloc directly for storage, and abort if we don't get what we
2709 want. The situation is much simpler --- just call malloc. Emacs
2710 has bizarre/evil requirements (signal handlers might malloc unless
2711 you set this global flag, so you have to set the flag around all
2712 calls to malloc) which we are certainly not going to conform to,
2713 so we can do the simple and obvious thing.
2715 * coop.c (coop_condition_variable_wait): Make this function
2716 static. It's only useful internally --- you should never just
2717 wait on a condition variable.
2718 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2720 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2722 * unif.c (scm_array_set_x): Accept any kind of number as an
2723 element for a uniform vector of doubles. This is more consistent
2724 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2726 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2727 works; I can't conveniently test it myself. (Thanks to Dvid
2728 Tillman for the bug report.)
2730 * init.c: Doc fixes.
2732 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2733 from here, not from scm_compile_shell_switches (which is a pretty
2734 dumb place to do it).
2735 (scm_load_startup_files): New function.
2736 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2737 * script.c (scm_compile_shell_switches): Don't load the startup
2739 (scm_ice_9_already_loaded): Variable moved.
2740 * init.c (scm_load_startup_files): Prototype for new function.
2741 * gh_init.c (gh_enter): Doc fix.
2743 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2745 Some anti-warning changes from Greg Harvey.
2746 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2747 warnings when it doesn't understand our NORETURN declarations in
2749 * posix.c (scm_mknod): Similar.
2751 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2753 * posix.c (scm_getpwuid): If we can't find an entry, return our
2754 own message, instead of using scm_syserror --- the getpwMUMBLE
2755 functions don't set `errno' to anything interesting.
2757 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2759 Get rid of warnings from the cooperative threading system.
2760 * threads.h (scm_single_thread_p, scm_yield,
2761 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2762 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2763 scm_wait_condition_variable, scm_signal_condition_variable): Add
2764 prototypes for these Scheme-visible functions.
2765 * coop-defs.h (coop_next_runnable_thread,
2766 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2767 Prototypes for these here, even though they're from iselect.c.
2768 (coop_condition_variable_wait, coop_join): Add prototypes.
2769 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2770 scm_threads_free_condvar): Make these smob functions static.
2771 * coop-threads.h (coop_init): Give this a real prototype.
2772 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2773 (coop_next_runnable_thread): No need to provide prototype; it's in
2776 * scmconfig.h.in: .detarenegeR
2778 * iselect.c, threads.c: Doc fixes.
2780 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2782 * Makefile.in: Regenerated with a patched automake, to get
2783 dependency generation right when using EGCS.
2785 * inet_aton.c (inet_aton): Add prototype, to remove compiler
2786 warning. (Thanks to Robert Pluim.)
2788 * inet_aton.c (inet_aton): Reassure the compiler that the
2789 arguments to the <ctype.h> macros are all unsigned characters, not
2792 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2794 Getting rid of more warnings...
2795 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
2796 today's change to ../configure.in.
2797 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
2798 * scmconfig.h.in: Regenertaded.de.,.__
2799 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
2800 (scm_localtime, scm_mktime): Use a const char * to manipulate the
2803 * readline.c: Doc fix.
2804 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
2805 * readline.h (scm_filename_completion_function): Add prototype.
2806 (scm_init_readline): Make this into a prototype.
2808 * readline.c (scm_filename_completion_function): Use SCM_PROC to
2809 declare this, instead of calling scm_make_subr manually.
2811 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
2813 * readline.h (scm_init_readline): Add prototype for this.
2814 (scm_init_readline): Make this a real prototype.
2816 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
2818 Warning fixes from Maciej Stachowiak:
2819 * backtrace.h (scm_display_application, scm_backtrace): Add
2821 * debug.c (scm_m_start_stack): Make this function static.
2822 * fluids.h (scm_fluid_p): Add prototype.
2823 * procprop.c (scm_i_procedure_arity): Make this function static.
2824 * regex-posix.c (scm_regexp_error_msg): Make this function static.
2825 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
2826 * root.h (scm_dynamic_root): Add external prototype.
2827 * scmsigs.h (scm_usleep): Add external prototype.
2828 * script.h (scm_init_script): Use prototype, not K&R decl.
2829 * stacks.h (scm_stack_id): Add external prototype.
2830 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
2832 1998-09-30 Mark Galassi <rosalia@cygnus.com>
2834 * gh.h: took out the definitions of vset and vref, since they are
2835 replaced by the proper vector routines that correspond to the R4RS
2838 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
2840 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
2841 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
2842 third argument, a C expression that should result in a SCM value,
2843 which is used to initialize the variable. Reimplemented
2844 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
2847 * version.h (scm_libguile_config_stamp): Add prototype.
2848 (From Maciej Stachowiak.)
2850 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
2852 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
2853 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
2855 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
2857 * print.c (scm_iprin1): Rather than having one i, and using it in
2858 several places, declare a fresh i local to each block where it is
2859 used, and give it a signedness appropriate to its use in each case.
2860 (scm_iprlist): Same.
2862 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
2863 comparison warnings.
2865 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
2866 signed/unsigned clashes.
2868 * posix.h (scm_tmpnam): Added prototype.
2870 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
2871 scm_make_subclass_object): Add external prototypes.
2873 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
2874 comparison is okay here.
2876 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
2878 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
2879 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
2881 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
2884 * load.c (swap_port): Make this function static.
2886 * load.c (scm_search_path): Make max_path_len and max_ext_len
2887 unsigned, since they're compared against string sizes.
2889 * load.c (init_build_info): Make i unsigned.
2891 * ioext.h (scm_read_line): Add prototype.
2893 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
2894 scm_hash_fn_remove_x): Make hash bucket index local variable k
2895 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
2896 accurately as possible.
2898 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
2899 comparisons, and range checking to make sure those casts are
2902 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
2903 signed/unsigned comparisons.
2905 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
2906 avoid signed/unsigned comparisons.
2907 * smob.h (scm_numsmob): Change extern declaration to match.
2909 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
2910 avoid signed/unsigned comparisons.
2911 * ports.h (scm_numptob): Change extern declaration to match.
2912 (scm_current_load_port, scm_set_port_line_x,
2913 scm_set_port_column_x): New prototypes.
2915 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
2916 test code, and it causes warnings.
2918 * gh.h (gh_int2scmb, gh_uniform_vector_length,
2919 gh_uniform_vector_ref): Added prototypes.
2921 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
2922 debugging support unconditionally. That's backtrace.c, stack.c,
2923 debug.c, and srcprop.c.
2924 (EXTRA_libguile_la_SOURCES): Omit those from here.
2925 * Makefile.in: Regenerated.
2927 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2929 * options.c (scm_options): Bugfix: Allow empty list of options!
2931 * debug.c, debug.h (scm_single_step): Removed.
2932 (scm_with_traps): New procedure. This procedure could easily be
2933 written in Scheme but needs to be highly optimized.
2935 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
2937 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
2938 Check SCM_TRAPS_P before trapping.
2940 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
2942 Changes to avoid signed/unsigned comparison warnings.
2943 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
2944 (scm_gc_sweep): Make n and j local to the blocks they're used in,
2945 so they can have appropriate types for each application. Make i
2946 signed. Use initializers in some spots. I'll probably pay for
2948 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
2949 (scm_must_realloc): Make nm unsigned.
2950 (init_heap_seg): Make new_seg_index and n_new_objects signed.
2951 (scm_init_storage): Use prototype-style definition, and make the
2953 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
2954 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
2956 * filesys.c (scm_readlink): Make local vars rv and size ints, to
2957 avoid signed/unsigned comparison warnings, and because the return
2958 value of readlink may be -1. Don't bother casting the third
2959 argument to readlink.
2961 * filesys.c (scm_dirname, scm_basename): Move these to their own
2962 page, at the end of the file.
2963 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
2965 * eval.h (scm_eval_options_interface): Add external prototype for this.
2966 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
2968 * eval.c (scm_lookupcar1): Make this static.
2970 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
2971 Make these prototype declarations, not K&R-style.
2973 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
2974 unsigned comparison warning.
2976 * appinit.c: File removed. It had a single function in it, empty,
2977 whose reason for existence is explained in no documentation or
2978 comment. I think it's there as a default for some Tcl-style
2979 initialization, but Tcl abandoned that approach a while ago.
2980 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
2981 (BUILT_SOURCES): Remove appinit.x.
2982 * Makefile.in: Regenerated.
2984 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
2986 * Makefile.in: Regenerated using the last public version of
2987 automake, not the hacked Cygnus version.
2989 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
2991 Remove Totoro kludge.
2992 * Makefile.in, scmconfig.h.in: Regenerated.
2993 * init.c, readline.c: Don't check if TOTORO is #defined.
2995 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
2997 * Makefile.am: Adjust for new thread configuration system.
2998 (INCLUDES): Include the value of THREAD_CPPFLAGS.
2999 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
3001 (THREAD_LIBS): Definition deleted; automake will generate such
3002 things automatically.
3003 * Makefile.in: Regenerated.
3005 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
3007 Simplify smob and port marking; set the mark bit in the generic
3008 marking code, and make marker routines only responsible for
3009 turning up outgoing pointers.
3010 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
3011 before calling the marking function. Don't call the marking
3012 function if it's zero.
3013 * markers.c (scm_mark0): Just return #f. This function isn't
3014 necessary at all now, but it's harmless to call it. We'll leave
3015 it in so other folks' code doesn't croak at link time.
3016 (scm_markcdr): Don't call SCM_SETGC8MARK.
3017 * async.c (mark_async): Don't call SCM_SETGC8MARK.
3018 * dynl.c (mark_dynl_obj): Same.
3019 * root.c (mark_root): Same.
3020 * srcprop.c (marksrcprops): Same.
3021 * unif.c (markra): Same.
3022 * variable.c (scm_markvar): Same.
3023 * ports.c (scm_markstream): Same.
3024 (void_port_ptob): Specify zero for our marking function.
3025 * debug.c (debugobjsmob): Same.
3026 * dynwind.c (guardsmob): Same.
3027 * filesys.c (dir_smob): Same.
3028 * fluids.c (fluid_smob): Same.
3029 * fports.c (scm_fptob, scm_pipob): Same.
3030 * mallocs.c (mallocsmob): Same.
3031 * regex-posix.c (regex_t_smob): Same.
3032 * smob.c (freecell, flob, bigob): Same.
3033 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
3034 * throw.c (jbsmob, lazy_catch_funs): Same.
3036 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3038 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
3039 scm_copy_tree on code in order not to let memoized code to leak
3040 out. Thus, scm_copy_tree needs to copy vectors as well since
3041 quasiquote can introduce evaluated code also inside vector
3044 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3046 * eval.c (scm_copy_tree): Removed ability to copy vectors.
3048 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
3049 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
3052 * unif.c: Say that ivect and uvect are of type signed and unsigned
3053 long instead of int in commentary so that it correctly describes
3056 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3058 * stime.c: Removed declaration of strptime. (It should be
3059 declared by the system headers. If it turns out that some systems
3060 don't, we'll handle that then.) (Thanks to Greg Troxel.)
3062 * stime.h: Renamed TIMEH --> STIMEH
3064 * backtrace.c (scm_display_error, scm_display_backtrace): In order
3065 to increase portability, don't use structure assignment.
3066 (Thanks to Nicolas Neuss.)
3068 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
3070 (finalize_fd_sets): Added empty statement after last case label.
3071 (Thanks to Nicolas Neuss.)
3073 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
3076 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
3078 * init.c, readline.c: OK, I won't have these readline.x bug
3079 reports anymore. We've had them since April. The current reason
3080 is a completely unintelligible failure of totoro.red-bean.com to
3081 do the test for rl_getc_function in libreadline correctly. This
3082 kludge overrides the test if we're on totoro so that the snapshot
3083 generation process can work.
3085 * readline.c: Define a strdup replacement if not existent on system.
3087 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3089 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
3090 This change makes scm_make_vector R5RS compatible. We cannot keep
3091 the third argument since people want to be able to deduce the form
3092 of the C function call only by looking at R5RS. (At the same time
3093 we have removed some unnecessary complexity!)
3095 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
3096 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
3097 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
3098 argument in call to scm_make_vector.
3100 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3102 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
3103 This macro is useful in applications.
3105 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3107 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
3108 (scm_parse_path, scm_search_path): New Scheme level procedures.
3110 * load.h (scm_internal_parse_path, scm_parse_path,
3111 scm_search_path): Declared.
3113 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3115 * filesys.c (dirname, basename): New procedures.
3117 * init.c (scm_boot_guile_1): Removed condition around
3120 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
3121 new data type (guards) for representation of C level guards and
3122 data on the wind chain.
3123 (scm_internal_dynamic_wind): New function.
3125 * dynwind.h: Declare scm_internal_dynamic_wind.
3127 * root.h (scm_root_state): Added scm_cur_loadp.
3129 * root.c (mark_root): Added comment about cur_loadp.
3131 * load.c: #include "dynwind.h";
3132 (scm_primitive_load): Use scm_inner_dynamic_wind to update
3135 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
3137 * ports.c (current-load-port): New procedure.
3139 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3141 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
3142 not a tty, return #f.
3144 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
3145 to Julian Satchell and Roland Kaufmann.)
3147 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
3148 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
3150 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
3152 * debug.h, debug.c (scm_start_stack): New function. Implements
3153 the guts of old scm_m_start_stack.
3155 * debug.c (scm_m_start_stack): Use scm_start_stack.
3157 * init.c (scm_start_stack, scm_restart_stack): Renamed to
3158 start_stack and restart_stack. (These have static scope.)
3160 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3162 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
3163 readline functions to come in release 2.3. (Thanks to Chet
3165 (handle_errors): Use the above functions.
3167 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3169 * readline.c: Improvements for readline support: Handle errors
3170 better; Implement before-read-hook.
3172 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3174 * init.c (scm_boot_guile_1), readline.c: Test for
3175 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3176 assure that we have version >= 2.1.)
3178 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3180 * readline.c (scm_readline): Defer interrupts while we're calling
3183 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3184 away the string to add_history.
3185 (completion_function): Do completion for readline. (Thanks to
3187 (scm_filename_completion_function): New procedure: Filename
3189 (current_input_getc): New function. Use this one instead of
3190 standard getc from readline.
3192 * throw.c, throw.h (scm_handle_by_throw): New function: This
3193 handler throws errors to next handler on the dynwind chain.
3195 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3197 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3200 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3202 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3204 (scm_procedure_properties): Modified to return arity together with
3206 (scm_procedure_property): Added the read-only property `arity'.
3207 (scm_set_procedure_property_x): It is an error to set the `arity'
3210 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3211 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3213 * procprop.h (scm_sym_arity): New symbol.
3215 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3216 to set the dispatch procedure of an operator or entity object.
3218 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3219 Made procedure slots read-only.
3221 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3222 scm_tcs_cons_gloc case in zero args switch; Fixed args
3223 construction for operators in scm_tcs_cons_gloc case in two args
3226 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3228 * fluids.c: Removed use of assert.h (in order to avoid
3231 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3233 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3235 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3236 change makes the evaluator safer at the cost of evaluation speed.
3237 It handles the case when the user has added a non-immediate
3238 improper end of the application form, e.g., `(+ 0 . x)'.
3239 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3240 minimize the extra cost as much as possible. The new code is
3241 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3242 problem with structs planted directly in the code (e.g. by a
3243 macro). This no longer causes segmentation fault. (Thanks to
3246 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3247 arg `proc' in order to be able to throw errors; New argument
3250 * Removed extra #include "debug.h"
3252 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3254 * scmsigs.c: Declare usleep as returning void on some systems.
3255 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3258 * coop.c (usleep): Return void on some systems.
3260 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3262 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3264 * coop.c: Changed return type of usleep to int.
3266 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3267 isn't found in the OS.
3269 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3270 isn't enabled. (Thought that I had made this change ages ago...)
3272 * iselect.c: Declare bzero if not defined by OS.
3274 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3276 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3277 condition. (Thanks to John Tobey.)
3279 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3280 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3283 * __scm.h: Start the long-term project of moving to POSIX threads.
3284 Phase 1: Classification of all critical sections.
3285 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3286 for A sections. (See comments in __scm.h for details.)
3288 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3289 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3291 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3293 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3294 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3295 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3296 dependencies on $(srcdir)/Makefile.in
3297 $(top_builddir)/config.status in order to avoid circularity.
3299 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3300 from argc if argc was 0 initially.
3302 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3303 in generation of libpath.h.
3305 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3307 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3308 libguile from 2 to 3.
3310 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3312 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3314 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3316 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3317 scm_set_port_column_x, scm_port_filename,
3318 scm_set_port_filename_x): Removed optional arguments. Added
3319 proper argument checking.
3321 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3322 stack size in machine words.
3324 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3325 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3326 to Ole Myren Röhne.)
3328 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3330 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3331 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3333 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3336 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3337 procedure apply: Copy argument lists before pushing them unto the
3338 environment so that the environment won't get mutated due to
3339 manipulation of procedure arguments. This should perhaps be
3340 regarded as a temporary solution until someone finds a more
3341 efficient one. (Thanks to Maciej Stachowiak.)
3343 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3345 * script.c (scm_compile_shell_switches): Use "guile" as default
3346 zero arg if argc is NULL.
3348 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3350 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3351 is zero. (Thanks to Dirk Herrmann.)
3353 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3355 * ports.c (scm_add_to_port_table): First line is now line 0
3356 (was 1). (Interface changed according to suggestion by Per
3359 * backtrace.c (display_header): Add 1 to line and column numbers
3360 when presenting them to the user.
3362 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3363 from debug.c --> eval.c
3365 * eval.h, eval.c (scm_eval_options_interface): New options
3367 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3368 i.e. stacks for new threads.
3370 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3372 * eval.c (unsafe_setjmp): Removed with #if 0.
3374 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3377 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3378 to avoid compiler warnings.
3380 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3382 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3384 * throw.c (handler_message): Print message on current error port
3385 instead of default error port. (Thanks to Maciej Stachowiak.)
3387 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3389 * ports.c (scm_add_to_port_table): allocate in units of
3390 struct scm_port_table *, not struct scm_port_table.
3391 * posix.c (scm_close_pipe): remove the port from the port table
3393 Thanks to Rob Engle for both fixes.
3395 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3397 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3398 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3400 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3402 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3404 * backtrace.c (display_error_body, display_backtrace_body),
3405 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3406 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3407 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3408 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3411 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3412 don't receive the jmpbuf arg anylonger.
3413 (scm_catch): Don't accept a #f tag.
3414 (scm_throw): Check that key is a symbol.
3415 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3417 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3419 * async.c (async_pending): Removed declaration.
3421 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3423 * dynwind.c (scm_wind_chain): New debug function.
3425 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3426 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3427 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3428 extra layer of functions around the body and handler of a thread.
3429 This extra layer makes sure that the handler is called in the
3430 dynamic context of the surround (= empty dynwind list), but under
3431 the *dynamic root* of the body. We can not use the dynamic root
3432 of the surround since that root belongs to another thread => stack
3433 is not handled correctly. It may seem ugly to use this extra
3434 layer, but the extra cost in terms of execution time is really
3435 negligible compared to the total amount of time required to create
3436 a thread, and it would reduce maintainability to duplicate the
3437 crucial and complicated steps performed by cwdr.
3439 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3440 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3441 get re-enabled. The important effect of this is that interrupts
3442 are blocked during thread switching so that thread data structures
3443 don't risk getting messed up by an unfortunate signal.
3444 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3445 seems to do more aggressive optimization which actually move
3446 instructions around in these macros in a fatal way. Therefore:
3447 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3448 just superstitious...)
3449 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3450 This macro should be used instead of SCM_ASYNC_TICK since the
3451 latter doesn't do context switches any more.
3453 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3454 instead of SCM_ASYNC_TICK.
3456 * coop.c, iselect.c: Since thread switches are now performed with
3457 interrupts masked, we can't use the old mechanism of delivering
3458 signals immediately when they arrive. Signals must instead be
3459 delivered when the asyncs run *after* the end of the critical
3460 section in scm_internal_select. But this also means after context
3461 switch so that the signal will be delivered to a different thread.
3462 To avoid this, I have changed the protocol of
3463 coop_wait_for_runnable_thread and friends so that they are allowed
3464 to return the original thread. So, if a signal arrives during
3465 scm_internal_select, we won't any longer be forced do a context
3466 switch, but can remain in the same thread and deliver the signal
3469 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3470 scm_asyncs_pending and made it global.
3472 * iselect.c: Small fixes.
3474 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3475 coop_condition_variable_init, coop_condition_variable_wait,
3476 coop_condition_variable_signal): Changed return type from `void'
3477 to `int'. This is to adhere closer to the pthreads interface.
3478 This, in turn, is part of an attempt to provide C versions of the
3479 mutex and condition variable primitives which can be part of a
3480 frontend to COOP or pthreads.
3482 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3483 coop_condition_variable_destroy): New functions.
3485 * coop-threads.c (scm_wait_condition_variable): Use
3486 coop_condition_variable_wait_mutex.
3488 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3489 Definitions moved to coop-defs.h.
3491 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3492 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3493 scm_cond_destroy): New C interface to mutecis and cond vars.
3495 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3497 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3499 * iselect.c: Now several threads can wait on the same file
3500 descriptor. The behaviour is compatible with OS select: All
3501 threads waiting for the fd return with the same status.
3503 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3505 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3506 Can spawn a thread from application C code.
3508 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3510 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3511 gh_doubles2scm): New functions.
3513 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3515 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3516 commented-out version of gh_eval_str()
3518 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3520 * socket.c (scm_bind): free soka after use.
3522 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3524 * stime.c (tzvar): new variable.
3525 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3526 avoid memory leaks when allocating.
3528 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3530 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3533 * gc.c, tags.h: Doc fixes.
3535 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3537 * eval.c (macro-eval!): Removed. This function was a design bug.
3538 It allowed memoized code to leak out to the scheme level. Most
3539 things that you could do with `macro-eval!' can be done with
3542 1997-12-20 Tim Pierce <twp@skepsis.com>
3544 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3545 scm_fgets now depends on ftell(3) to know how many bytes were
3548 1997-12-15 Tim Pierce <twp@skepsis.com>
3550 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3551 dealing with strings.
3553 1997-12-13 Tim Pierce <twp@skepsis.com>
3555 Make %read-line more suitable for implementing read-line efficiently.
3556 * ioext.c (scm_read_line): Strip the terminating newline from a
3557 string, and return a cons of the string and its terminator.
3559 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3560 of the string that is read is stored in this memory location.
3561 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3562 * genio.c, genio.h (scm_do_read_line): Update caller.
3563 * ports.h (scm_ptobfuns): Update typedef.
3564 * fports.c (scm_fptob, scm_pipob): Update struct.
3566 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3568 * filesys.c (set_element): Return file descriptor.
3569 (fill_select_type): Return the highest file descriptor.
3570 (scm_select): Tell select about the highest file descriptor. On
3571 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3572 Therefore the extra overhead for calculating the maximum fd seems
3573 to be more than compensated. Is this correct? In any case,
3574 scm_internal_select will be much faster with this info.
3575 (scm_select, fill_select_type, set_element): Don't accept any kind
3576 of object in the file descriptor list or vector.
3578 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3580 * iselect.c (finalize_fd_sets): Bugfix.
3582 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3584 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3585 when using scm_internal_select (since we might switch to another
3588 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3590 * simpos.c (scm_system): always define: use sysmissing if not
3591 available. Check for HAVE_SYSTEM instead of _Windows (does
3592 Windows lack system or does it have an unusable one?).
3593 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3594 Let the argument be optional: if not supplied, call system(NULL).
3596 * ports.c (scm_close_port): relax the type check from OPPORTP to
3597 PORTP; closing a closed port is allowed.
3599 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3601 * fports.c (scm_fgets): Return if the last char in a chunk is
3602 newline. When fgets returns a string whose length is `size-1', it
3603 is ambiguous whether a whole line was retrieved, so we must check
3604 explicitly whether a line terminator is present.
3606 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3608 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3609 before taking the CDR. (Thanks to Harald Meland.)
3611 * filesys.c (scm_stat): Slightly optimized.
3613 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3615 * ports.c (scm_close_port): Make sure the port is open before
3618 * guile-snarf.in: Pass args through to gcc in a way that preserves
3619 whitespace boundaries. (Thanks to Greg Badros.)
3621 1997-12-02 Tim Pierce <twp@skepsis.com>
3623 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3624 statement. (Thanks to Doug Evans for pointing this out.)
3626 1997-12-01 Tim Pierce <twp@skepsis.com>
3628 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3630 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3632 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3633 errno macro expansion of this field name. (errno is a C
3634 preprocessor macro on some systems.)
3636 1997-11-29 Tim Pierce <twp@skepsis.com>
3638 * iselect.c: Doc fix.
3640 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3642 * init.c (scm_start_stack): Removed initialization of
3643 scm_the_last_stack_var.
3645 * backtrace.h: Declare scm_the_last_stack_var.
3647 * backtrace.c: Define scm_the_last_stack_var.
3649 * root.c (mark_root): Don't mark the_last_stack_var.
3651 * root.h (scm_root_state): Removed the_last_stack_var.
3653 * throw.c: Added #include "fluids.h"
3654 (ss_handler): `the-last-stack' is now a fluid.
3656 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3657 --> the_last_stack_fluid.
3659 * backtrace.c: Added #include "fluids.h"
3660 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3661 (scm_backtrace): `the-last-stack' is now a fluid.
3663 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3664 after scm_init_fluids.
3666 1997-11-28 Tim Pierce <twp@skepsis.com>
3668 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3670 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3671 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3673 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3675 * iselect.c (coop_next_runnable_thread,
3676 coop_wait_for_runnable_thread): Disable interrupts so that no
3677 async is executed before a potential error_revive.
3678 (scm_internal_select): Disable interrupts during the parts of the
3679 code which manipulate the sleep queue and the file descriptors.
3681 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3683 * Makefile.am: Added iselect.c and iselect.h.
3685 * coop.c (coop_qinit): Initialize fields used by
3686 scm_internal_select.
3687 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3688 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3689 replacement in iselect.c.
3690 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3691 coop_join): If GUILE_ISELECT enabled, use
3692 coop_wait_for_runnable_thread instead of
3693 coop_next_runnable_thread.
3694 (usleep, sleep): New replacements for system functions if
3695 GUILE_ISELECT is enabled.
3697 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3699 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3701 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3702 iselect.h. Implement Scheme level `select' using
3703 scm_internal_select. (See NEWS.)
3705 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3707 * init.c: Call scm_init_iselect.
3709 * iselect.h, iselect.c: New files. Implements
3710 scm_internal_select. (See NEWS.)
3712 1997-11-27 Tim Pierce <twp@skepsis.com>
3714 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3715 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3716 and scm_must_free, since ultimately the string returned will be copied
3717 by scm_makfrom0str anyway. Also, read any characters that may have
3718 been pushed onto the port with scm_ungetc.
3719 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3720 * ioext.c (scm_read_line): Free string after Guilifying it.
3721 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.
3723 1997-11-26 Anthony Green <green@hoser.cygnus.com>
3725 * gh_data.c (gh_set_substr): Strings can be longer than 256 bytes.
3727 * gh.h: Safely wrap prototypes for c++ usage.
3729 1997-11-25 Mark Galassi <rosalia@cygnus.com>
3731 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3732 gh_repl (argc, argv).
3734 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3736 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3737 and to invoke scm_shell().
3738 (gh_launch_pad): took out the loading of boot-9.scm from here,
3739 since it is probably best to let the user control that. In fact,
3740 gh_repl() now invokes scm_shell() which does that.
3742 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3744 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3747 1997-11-22 Tim Pierce <twp@twp.tezcat.com>
3749 * dynl-dl.c (sysdep_dynl_func): Fix memory leak created by
3750 yesterday's underscore patch. (Thanks to Marius Vollmer for
3753 1997-11-21 Tim Pierce <twp@twp.tezcat.com>
3755 * dynl-dl.c (sysdep_dynl_func): Prepend symb with underscore if
3756 DLSYM_ADDS_USCORE is not defined.
3758 1997-11-17 Mark Galassi <rosalia@nis.lanl.gov>
3760 * gh_data.c (gh_uniform_vector_length):
3761 (gh_uniform_vector_ref): started implementing the uniform types in
3764 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
3766 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3767 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3769 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3771 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
3772 configure.in was changed).
3774 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
3776 * Makefile.am (modinclude_HEADERS): Include readline.h here.
3777 * Makefile.in: Regenerated.
3779 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
3781 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
3782 OPORT is an `open' port, not an output port.
3784 * filesys.c (scm_close, set_element, get_element, scm_chown,
3785 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use
3786 SCM_COERCE_OUTPORT to cope with the printstate/port magic.
3787 * ports.c (scm_port_revealed, scm_set_port_revealed_x,
3788 scm_close_port, scm_port_line, scm_set_port_line_x,
3789 scm_port_column, scm_set_port_column_x, scm_port_filename,
3790 scm_set_port_filename_x, scm_port_mode,
3791 scm_close_all_ports_except, scm_set_current_output_port,
3792 scm_set_current_error_port): Likewise
3793 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
3794 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
3796 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
3797 * backtrace.c (display_backtrace_body): Likewise
3798 * fports (scm_setvbuf): Likewise
3799 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,
3800 scm_connect, scm_bind, scm_listen, scm_accept, scm_getsockname,
3801 scm_getpeername, scm_send, scm_sendto): Likewise
3802 * unif.c (scm_uniform_array_write): Likewise
3804 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
3806 Minor problems with substring-related tag changes.
3807 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
3808 exactly what we want to leave in to detect substrings.
3809 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
3810 * tags.h: Fix diagrams and comments describing the S tag bit;
3811 remove vestigial remarks about the D tag bit.
3812 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
3813 * strings.c: Formatting tweaks.
3815 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
3816 variable first; then SCHEME_LOAD_PATH, with a warning message.
3817 (scm_parse_path): New function.
3818 * script.c: Doc fixes.
3820 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
3822 Readline support, from Daniel Risacher.
3823 * readline.c, readline.h: New files.
3824 * init.c: #include "readline.h".
3825 (scm_boot_guile_1): Call scm_init_readline, if we have it.
3826 * Makefile.am (libguile_la_SOURCES): Include readline.c.
3827 * Makefile.in: Regenerated.
3828 * scmconfig.h.in: Regenerated, after change to ../configure.
3830 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3832 * gh.h: gh_vector_set -> gh_vector_set_x
3834 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3836 * gh_data.c (gh_vector_set_x): changed name to make it consistent
3837 with the ! -> _x mapping when going from Scheme to C.
3839 1997-10-19 Mark Galassi <rosalia@cygnus.com>
3841 * gh.h (gh_reverse):
3849 (gh_assoc): added these gh_ functions implemented as macros.
3851 * gh_predicates.c (gh_null_p):
3852 (gh_string_equal_p): added these two missing predicates.
3854 * gh_list.c (gh_append):
3859 (gh_set_cdr_x): added these routines as I go through and try to
3860 complete the picture R4RS functions that should be mirrored in the
3863 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3865 * tags.h (scm_tc7_substring): Changed the comment and code to
3866 conform with the changes below. Folks! We have suddenly two new
3867 free tc7 codes!!! Jummy, jummy!
3869 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
3871 * Makefile.in: Rebuilt.
3872 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,
3874 (modinclude_HEADERS): Removed extchrs.h, mbstrings.h.
3875 * unif.c (scm_vector_set_length_x): Don't handle multibyte
3877 * tag.c (scm_utag_mb_string, scm_utag_mb_substring): Removed.

3887 (scm_gc_sweep): Likewise.
3888 * eval.c (SCM_CEVAL): Don't handle mbstrings.
3889 * eq.c (scm_equal_p): Use SCM_TYP7S, not SCM_TYP7SD.
3890 * tags.h (SCM_TYP7SD): Removed.
3891 (SCM_TYP7D): Removed.
3892 (scm_tc7_mb_string): Removed.
3893 (scm_tc7_mb_substring): Removed.
3894 * print.c (scm_iprin1): Handle char printing directly. Don't
3896 Don't include "mbstrings.h".
3897 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
3898 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
3900 Don't include "mbstrings.h".
3901 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
3902 (SCM_SYMBOL_SLOTS): Define as 4.
3903 (SCM_ROSTRINGP): Use SCM_TYP7S, not SCM_TYP7SD.
3904 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
3905 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
3906 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,

3924 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
3925 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
3927 1997-10-12 Mark Galassi <rosalia@cygnus.com>
3929 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
3931 * gh_test_c.c (c_vector_test): some improvements on the vector
3934 * gh.h (gh_vector): this used to exist but do the wrong thing.
3935 Now it (almost) does the right thing, though it takes a list
3936 instead of the individual arguments. I need to see how it could
3938 (gh_list_to_vector): added this function as a macro. Corresponds
3939 to Scheme's (list->vector ...).
3940 (gh_vector_to_list): added this function as a macro. Corresponds
3941 to Scheme's (vector->list ...).
3943 * gh_data.c (gh_vector_ref): renamed from gh_vref to
3944 gh_vector_ref, so that it resembles the Scheme routines more.
3945 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
3946 resembles the Scheme routines more.
3947 (gh_make_vector): this used to be (stupidly) called gh_vector().
3948 This is the right name, since it does the same thing as the Scheme
3949 (make-vector ...) procedure.
3951 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
3953 * ports.h: #include "libguile/print.h"
3955 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
3956 Some indentation fixes.
3958 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
3959 longer a user field; New field: class_flags.
3961 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
3963 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
3965 * gh_data.c (gh_bool2scm): new function which replaces
3966 gh_int2scmb(), which is now tagged as obsolete.
3968 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
3970 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
3971 macros should by convention not test for NIMPness.)
3972 (SCM_COERCE_OPORT): Adjust indentation.
3974 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
3975 SCM_NIMP test before SCM_PRINT_STATE_P.
3977 * struct.c, struct.h, gc.c: Renamed:
3978 scm_struct_i_layout --> scm_vtable_index_layout
3979 scm_struct_i_vcell --> scm_vtable_index_vcell
3980 scm_struct_i_vtable --> scm_vtable_index_vtable
3981 scm_struct_i_printer --> scm_vtable_index_printer
3982 scm_struct_i_vtable_offset --> scm_vtable_offset_user
3984 * struct.c (scm_print_struct): Use new printer slot; Default
3985 printing: Also output hex code of vtable so that type identity
3986 will be indicated as well.
3987 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
3988 Removed struct_printer_var; Removed struct-vtable-offset;
3989 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
3990 vtable-offset-user): New constants.
3992 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
3993 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
3994 If this slot contains a procedure, use that to print structures of
3995 the type represented by this vtable.
3997 * print.c (scm_iprin1): Don't print arguments of macro
3998 transformers. (They are always: exp env.); Bugfix: Unmemoize
3999 transformer source with correct environment.
4001 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
4003 Streamlining of call-with-dynamic-root:
4005 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
4006 there is now only one catch.
4007 (cwdr_outer_body): Removed.
4008 (cwdr_handler): New function.
4009 (scm_internal_cwdr): New function to perform the function of cwdr
4010 but take args that are more useful to C code. Also, the handler
4011 is now invoked *outside* of the new dynamic root, like the docs
4012 say. We no longer have to catch absolutely all errors, the caller
4013 is responsible for using a handler that does not throw, if he
4015 (cwdr): Reimplemented in terms of scm_internal_cwdr.
4016 * root.h (scm_internal_cwdr): New prototype.
4018 Even more but risky streamlining:
4020 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
4021 allocation of the jumpbuf of a root continuation. The changes
4022 below are controlled by it. They are now deactivated.
4023 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
4024 the JMPBUF of the scm_rootcont to NULL before returning.
4026 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
4027 when they are non-NULL.
4028 (scm_gc_mark): Likewise, mark only when non-NULL.
4030 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
4031 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
4033 * gc.c (scm_done_malloc): New function.
4034 gc.h (scm_done_malloc): New prototype.
4036 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.
4037 (struct scm_print_state) [revealed]: New field.
4038 (scm_print_state_vtable): Make visible to the outside world for
4039 type checking purposes.
4040 (scm_valid_oport_value_p): New prototype.
4042 * print.c (scm_valid_oport_value_p): New function to check whether
4043 a certain value is acceptable as a port argument.
4044 (scm_print_state_vtable): New variable.
4045 (scm_free_print_state): Set `revealed' field to false.
4046 (scm_iprin1): Call user supplied closure printer with
4047 scm_printer_apply. Print in the traditional way when there isn't
4048 one or when it returns #f.
4049 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
4050 Accept a port/print-state pair in addition to just a port.
4051 (scm_prin1): Don't return the print_state to the pool when it has
4053 (scm_printer_apply): Set `revealed' field of print_state to true.
4054 (scm_init_print): Set scm_print_state_vtable.
4055 (print_state_fluid, print_state_fluid_num): Removed.
4057 * throw.h (scm_handle_by_proc_catching_all): New prototype
4058 throw.c (scm_handle_by_proc_catching_all): New function
4060 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
4062 * Makefile.in: Regenerated with automake 1.2c.
4064 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
4066 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
4067 was looping endlessly.
4069 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
4071 * strports.c (scm_eval_string): Don't close the port.
4073 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
4074 former returns a nice normal integer. (Thanks to Daniel
4077 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
4079 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
4080 makefile variable as a build parameter called LIBS. The
4081 build-guile program will use this, for the time being.
4082 * Makefile.in: Regenerated.
4084 Thanks to Shiro Kawai:
4085 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
4086 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
4089 * Makefile.in: Regenerated with automake 1.2a.
4091 * script.c (scm_compile_shell_switches): If we hit the -c or --
4092 arguments, don't set the car of (command-line) to scm_usage_name,
4093 the prettified name of the guile executable; give it the full
4094 path, the way shells usually handle $0.
4096 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4098 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
4099 Scheme-level name `array-map' and renamed `serial-array-map' to
4100 `serial-array-map!'.
4102 * backtrace.c: Introduced exception handlers which now enclose
4103 `display-error' and `display-backtrace' so that error reporting
4104 won't get into infinite loops if an error occurs during displaying
4105 of the error. This can very easily happen with user supplied
4106 print call-back routines.
4108 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4110 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
4111 the names `serial-array-map' and `array-map' should be removed.)
4113 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
4115 * init.c (scm_boot_guile_1): Added scm_init_objects ().
4116 Added #include "objects.h"
4118 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
4119 Add #include "feature.h".
4121 * Makefile.am (libguile_la_SOURCES): Added objects.c.
4122 (modinclude_HEADERS): Added objects.h.
4124 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
4125 This test is needed at many places in the code and should be
4126 abstracted. (Motivated by the need of this test in libguiletk.)
4128 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
4129 (scm_eval_string), load.c (scm_primitive_load,
4130 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
4131 Use SCM_EOF_OBJECT_P.
4133 * eval.c (scm_init_eval): Add feature `delay'.
4135 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4137 * scmhob.h: Removed.
4139 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4141 * list.h (SCM_LISTn): New macros. Make list creation in C code
4142 prettier. The idea comes from STk.
4144 * sequences.h, sequences.c, append.h, append.c: Removed. These
4145 files implemented non-R4RS operations which would encourage
4146 non-portable programming style and less easy-to-read code.
4148 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
4151 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
4152 sequences.h, #include append.h.
4154 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
4157 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
4159 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
4161 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
4163 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4165 * eval.c: Added #include "objects.h"
4167 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
4170 * smob.c (scm_smob_prehistory): Create two objectsmobs with
4171 adjacent smob numbers.
4173 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4175 * procprop.h: Added declaration of scm_i_inner_name.
4177 * gsubr.c: New global symbol scm_i_inner_name.
4179 * debug.c (scm_procedure_name): Try procedure property
4180 `inner-name' if `name' fails.
4182 * print.c (scm_iprin1): Use scm_macro_name.
4184 * eval.c (scm_m_define): Give names to macros as well; Only the
4185 first top-level definition gives a procedure/macro a name.
4186 Otherwise confusing names can turn up in backtraces.
4187 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4188 `name'; Give names to macros as well.
4190 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4191 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4194 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4196 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4198 (prinmacro): Removed. The code has been moved/merged into print.c
4199 in order to decrease code redundancy. We want macros to print in
4200 a way equivalent to procedures, and it would be silly to duplicate
4201 the required code. (We don't want to maintain two places.)
4202 (macrosmob): Print field is now a NULL pointer.
4204 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4205 scm_macro_transformer): New prototypes.
4206 (scm_tc16_macro): Declared.
4208 * print.c (scm_iprin1): Added code for printing of macros. Macros
4209 are now printed in a way equivalent to procedures.
4211 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4213 * procs.h (scm_closure_p): Added declaration.
4215 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4217 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4218 Shouldn't pass "heap" as the subr name.
4220 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4222 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4223 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4224 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4225 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4226 SCM_BOOL_T. Any non-false value is true.
4228 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4230 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4231 scm_gensym): Added prototypes.
4233 * symbols.c (scm_gensym): New function. This will speed up
4234 certain types of applications (such as macro systems) which
4235 generate lots of symbols.
4237 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4239 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4241 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4243 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4244 specifier, since (2) or (2 . 3) would cause SEGV.
4245 (scm_transpose_array): more argument checking fixes.
4247 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4249 * Makefile.in: Regenerated.
4251 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4253 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4255 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4257 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4259 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4261 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4262 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4265 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4266 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4267 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
4268 scm_array_p, scm_array_rank, scm_array_dimensions,
4269 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
4270 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
4271 scm_array_prototype): Added case scm_tc7_wvect.
4273 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
4275 * errno.h: prototype for scm_strerror.
4276 * error.c (scm_strerror): new procedure.
4278 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4280 * list.c (scm_list_append_x): Allow non-pair as last argument.
4281 This is consistent with the R4RS append and is probably the
4282 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4284 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4286 * stime.h: prototype for scm_times.
4287 * stime.c (scm_times): new procedure.
4288 * ioext.c (scm_fseek): if the first argument is a file descriptor
4290 (scm_ftell): if the first argument is a file descriptor call lseek
4292 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
4293 * filesys.c (scm_chmod): if the first argument is a file descriptor,
4295 (scm_chown): if the first argument is a port or file descriptor,
4297 (scm_truncate_file): new procedure.
4298 Add DEFER/ALLOW INTS to a few other procedures.
4299 (scm_fsync): new procedure.
4300 (scm_open_fdes): new procedure.
4301 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
4303 (scm_fcntl): the first argument can now be a file descriptor. The
4304 third argument is now optional.
4306 * posix.c (scm_execl, scm_execlp): make the filename argument
4307 compulsory, since omitting it causes SEGV.
4308 (scm_sync): return unspecified instead of #f.
4309 (scm_execle): new procedure.
4310 (environ_list_to_c): new procedure.
4311 (scm_environ): use environ_list_to_c. disable interrupts.
4312 (scm_convert_exec_args): take pos and subr arguments and
4313 improve error checking.
4315 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4317 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4318 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4319 argument to SCM_ASSERT. Furthermore, the name of the function
4320 should be passed as first argument when signalling
4321 SCM_WNA. (Thanks to Thomas Morgan)
4323 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4324 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4325 dispatches on the number of actual args has a default case
4326 reporting an internal error. This is a vestige from a version
4327 that mallocated a SCM vector to hold the arguments. In the
4328 current version this check is too late: if it ever happens we will
4329 have already overstepped the bounds of the array.
4331 Also, the patch [...] adds a check for too many actual arguments."
4333 mdj: Removed check for "internal programming error".
4335 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4337 * gh_io.c (gh_write): New function.
4339 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
4340 throw.c (scm_internal_stack_catch): New sibling to the other catch
4341 functions. Code moved from gh_eval.c.
4342 throw.h: Added header.
4343 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
4344 scm_internal_stack_catch.
4346 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4348 * ioext.h: fix up prototypes.
4349 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
4350 Scheme name is now dup->fdes.
4351 (scm_dup_to_fdes): make the second argument optional and
4352 fold in the functionality of scm_primitive_dup.
4353 (scm_primitive_dup): deleted.
4355 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
4357 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
4358 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
4359 ultrix are defined. Use setvbuf instead of setbuf.
4360 (scm_setvbuf): new procedure.
4361 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
4362 (scm_setfileno): moved from ioext.c.
4363 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
4364 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
4366 Sun Jul 27 10:54:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4368 * fluids.c (scm_fluid_p): New function.
4369 * fluids.h (scm_fluid_p): New prototype.

4374 state as nested data while they are printed.
4375 (print_state_fluid, print_state_fluid_num): New variables.
4376 (scm_init_print): Initialize them.
4377 (scm_iprin): If print_state_fluid carries a print_state, use that
4378 instead of creating a new one.
4379 (scm_printer_apply, apply_stub, struct apply_data): New
4380 definitions to help with calling printer functions written in
4382 * print.h (scm_printer_apply): New prototype.

4395 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
4396 SCM_ASSERT: arg comes before pos.
4398 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4400 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
4401 to a list of length zero correctly.
4403 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4405 Supply an `fgets' method for port objects to do fast line i/o.

4419 * ioext.h: removed scm_duplicate_port prototype.
4421 * ioext.c (scm_primitive_dup2): return the new file descriptor
4422 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
4424 (scm_fdopen): bug fix: don't try to make port unbuffered until its
4425 stream has been set.
4426 (scm_duplicate_port): deleted, there's now an implementation in
4428 (scm_primitive_dup2): do nothing if newfd == oldfd.
4430 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
4432 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the
4435 * ioext.h: new prototypes.
4436 * ioext.c (scm_primitive_dup, scm_primitive_dup2): new procedures.
4438 * fluids.c (next_fluid_num): don't do
4439 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
4441 * ports.h: prototypes too.
4442 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
4444 * fports.h: prototype too.
4445 * fports.c (scm_evict_ports): moved from ioext.c.
4447 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>

4454 and ports (scsh compatible).
4456 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
4459 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
4461 * fluids.c, fluid.h: New files.
4462 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
4463 (modinclude_HEADERS): Added "fluids.h"
4465 * init.c: Include "fluids.h". (scm_boot_guile_1): Added call to

4471 * root.c: Include "fluids.h". (scm_mark_root): Mark "fluids".
4472 (scm_make_root): Call scm_copy_fluids to make fluid bindings
4473 unique for the new root when it has a parent.
4475 * smob.h: Include "libguile/print.h" to make scm_print_state
4478 * dynl.c (free_dynl_obj): New function to free the dynamic object
4479 data. (dynl_smob): Use it.
4480 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4481 the dynamic object data below the linking of the object to avoid
4482 memory leak when the linking code throws an error. Now the code
4483 leaks a whole dynamically linked library when must_malloc throws,
4484 but that should be much less likely.
4486 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4488 Changes to compile under gnu-win32, from Marcus Daniels:
4489 * stime.c (tzset): If tzset isn't provided, make it a NOP.
4490 (scm_localtime): Change SCM_EOF to SCM_EOL.
4491 (scm_mktime): Likewise.
4492 * socket.c: Don't include sys/un.h unless autoconf tells
4493 us Unix domain sockets are available.
4494 (scm_fill_sockaddr): Ignore Unix domain code.
4495 (scm_addr_vector): Likewise.
4496 (scm_init_addr_buffer): Likewise.

4499 * simpos.c (SYSTNAME): Treat cygwin like Unix.
4500 * scmsigs.c (scm_pause): Don't include unless pause was found
4502 * posix.c (scm_getgroups): Don't include unless support function
4503 was found during autoconf (in this case, getgroups).
4504 (scm_setpwent): For setpwent.
4505 (scm_setegid): For setegid.
4506 * net_db.c (scm_inet_netof): Don't include unless support
4507 function was found during autoconf (in this case, inet_netof).
4508 (scm_lnaof): For inet_lnaof.
4509 (scm_inet_makeaddr): For inet_makeaddr.
4510 (scm_getnet): For getnetent, getnetbyname, getnetbyaddr.

4521 * stime.c (scm_localtime, scm_mktime): Pass SCM_EOL to
4522 scm_misc_error, not SCM_EOF.
4524 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
4525 arguments for formatting the error message, not SCM_BOOL_F. I
4526 think this is left over from the (eq? '() #f) days.
4528 * read.c (recsexpr): Give this a dummy definition if
4529 DEBUG_EXTENSIONS isn't #defined.
4531 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>

4536 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>
4538 * root.c (cwdr_outer_body): Bugfix: Pass `c' instead of `&c' to
4541 Sat Jun 28 16:14:09 1997 Tim Pierce <twp@twp.tezcat.com>
4543 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
4544 alloca.lo will be included in @LIBLOBJS@. Something better than
4545 this should be possible.
4546 * Makefile.in: Regenerated.
4548 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4550 * simpos.h: prototype for scm_primitive_exit.
4551 * simpos.c (scm_primitive_exit): new procedure, terminates the
4552 process without unwinding the stack.
4554 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
4556 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
4557 argument and logior its components together, so the user doesn't
4558 have to do this explicitly. Also, if regexp/basic is supplied, then
4559 turn off REG_EXTENDED.
4560 (scm_init_regex_posix): New regexp/basic symbol.
4561 (REG_BASIC): #define this if it is not already present.
4563 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4565 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.
4566 (MOSTLYCLEANFILES): New target, changed from CLEANFILES.
4567 (CLEANFILES): New target, clean versiondat.h, libpath.h.
4568 (DISTCLEANFILES): New target, clean *.x.
4569 * Makefile.in: Regenerated.

4577 * Makefile.in: Regenerated.
4579 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
4580 flag; I don't think we support it.
4581 (scm_make_regexp): Make sure the user doesn't pass the
4584 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
4586 (scm_init_regex_posix): Define constants for the REG_mumble flags;
4587 name them according to the SCSH convention: regexp/mumble.
4589 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
4591 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>
4593 * Makefile.am (libpath.h): Include the values of all the standard
4594 Makefile directory variables. Print a message, but don't print
4596 (versiondat.h): Print a message, but don't print all the commands.
4597 * load.c: #include "alist.h".
4598 (init_build_info): New function.
4599 (scm_init_load): Call it.
4600 * Makefile.in: Regenerated.
4602 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
4604 * root.c: Establish a reliable catch-all handler for the new root.
4605 After all the Scheme handler function might signal an error too,
4606 and we don't want to lose that.
4607 (cwdr_inner_body): Renamed from cwdr_body.
4608 (cwdr_outer_body): New function, to establish the user's handler,
4609 and pass control to cwdr_inner_body.
4610 (cwdr): Establish the reliable catch-all handler here, and pass
4611 control to cwdr_outer_body.
4612 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
4613 the user's handler through to cwdr_outer_body.
4614 * throw.c (scm_handle_by_message): Move guts into....
4615 (handler_message): New static function.
4616 (scm_handle_by_message_noexit): New function.
4617 * throw.h (scm_handle_by_message_noexit): New prototype.
4619 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
4620 across this. Only works on GCC. Otherwise, we hope for the best.
4621 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4622 the feeling that real thread systems will not need this...
4624 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4626 Try to detect when people are using one version of libguile and a
4627 different version of ice-9. People have been skewing things and
4628 sending in bug reports.
4629 * Makefile.am (versiondat.h): New file to generate.
4630 * version.c: #include "versiondat.h", to get version info.
4631 (scm_libguile_config_stamp): New function.
4632 * script.c: #include "version.h".
4633 (scm_compile_switches): Call scm_version to get version number.
4634 * scmconfig.h.in, Makefile.in: Regenerated.
4635 * Makefile.in: Regenerated.
4637 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
4638 primitive definitions under their Scheme names.
4640 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4641 1:2. Helps avoid confusion between installed and uninstalled libs.
4643 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
4646 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
4647 backslash from definition; this should be used like: GDB_INTERFACE;
4649 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4651 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
4652 new port unbuffered until its stream has been set.
4654 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
4656 * ports.h: new prototype.
4657 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
4659 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
4661 Make things compile neatly under Sun's C compiler.
4662 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
4663 * extchrs.c (xmbtowc): Make the second arg a normal char, not
4664 unsigned, because that's what the ANSI function takes.
4665 * extchrs.h (xmbtowc): Corresponding change to prototype.
4666 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4668 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
4669 argument plain char *.
4670 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
4672 * tag.c (scm_tag): Remove unreachable statement.
4673 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4674 top of the word, it should be unsigned.
4676 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4677 is defined, to avoid warnings; it's only used in the
4678 conflict-checking code. Which might go away anyway.
4679 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4680 conditionals; put the label definition in an #if too, to stifle
4683 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4684 ChangeLog-threads in the distribution.
4685 * Makefile.in: Regenerated.
4687 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4689 * guile-snarf.in: Changed regexp to support CPPs that insert
4690 whitespace between lexical tokens (which munges the `%%%' snarf
4693 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4695 * load.c (scm_init_load_path): Append $(datadir)/guile to
4696 %load-path, so modules do not have to be installed in Guile's
4697 current version directory.
4699 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
4701 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
4702 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
4703 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
4704 call the sysdep functions with deferred ints.
4705 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
4706 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
4707 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
4710 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
4713 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
4715 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
4717 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
4719 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
4722 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
4724 * eval.c (scm_lookupcar1): New procedure to cope with a race
4725 condition during lookup (when using threads).
4726 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4727 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4730 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4732 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4733 supplied. (Change from Tim Pierce.)
4735 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4737 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4738 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4739 default and not `()'. `#f' is the canonical non-value in Scheme,
4742 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4744 * struct.c (struct_printer): New variable that holds a handle on
4745 the Scheme variable *struct-printer*. This variable can be set by
4746 Scheme code to override the printing of structures.
4747 (scm_print_struct): If struct_printer is set, call it. If it is
4748 not set, or returns #f, print the structure in the old fashion.
4749 Include "eval.h" for scm_apply.
4751 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4753 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4754 scm_struct_i_n_words to get the number of fields, not
4755 -scm_struct_n_extra_words.
4757 On the route to fancier struct printing:
4758 * struct.c (scm_print_struct): New function to print a structure.
4759 Include "genio.h" to support it. This function doesn't do
4760 anything interesting right now, but I think it should be here
4762 * struct.h: Include "print.h" and add prototype for
4764 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4765 print structures ourself.
4767 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4769 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
4770 before applying the handler in case it doesn't return.
4772 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
4774 * scmsigs.h, async.h: updated.
4776 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
4779 * posix.c (scm_uname): interpret only negative values as an error.
4780 Solaris normally returns a positive value.
4782 * script.c (scm_compile_shell_switches): if we are not going into
4783 an interactive repl, set scm_mask_ints to zero so that asyncs can
4786 * simpos.c (scm_system): don't ignore/unignore signals around
4789 * posix.c (scm_open_pipe): don't ignore/unignore signals around
4792 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
4793 done in boot-9.scm instead.
4795 * scmsigs.c, async.c: Major rewriting of signal handling code.
4796 (scm_sigaction): new procedure.
4797 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
4799 (scm_raise): return unspecified, throw error on failure.
4801 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4803 * regex-posix.c (scm_init_regex_posix): Register the "regex"
4804 feature, to help boot-9.scm decide whether to import the regex
4807 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
4809 * eval.c: Include scmconfig.h at the beginning of the file so that
4810 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
4813 * regex-posix.c: #include "_scm.h" before conditionally #including
4814 <regex.h>; the former defines HAVE_REGCOMP.
4816 * regex-posix.c: #include <regex.h> conditionally, so the file is
4817 CPP'able (for dependency scanning) even on systems that don't have
4820 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4822 Add new R4RS-compliant syntax for keywords.
4823 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
4824 regardless of the setting of the `keywords' read option.
4825 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
4826 can be re-read no matter what the setting of the `keywords' read
4829 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
4831 Add support for POSIX regular expressions.
4833 * regex-posix.c, regex-posix.h: New files. (Some code
4834 is taken liberally from rx/rgx.c in the old Guile dist.)
4836 * init.c: Include regex-posix.h.
4837 (scm_boot_guile_1): Call scm_init_regex_posix.
4839 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
4840 Add regex-posix.[ch] sources.
4841 * Makefile.in: Regenerated.
4843 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
4844 to do this automatically? It didn't for me, bleh.)
4846 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
4848 * fports.c (print_pipe_port): New function.
4849 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
4850 latter doesn't even take the right arguments.
4852 * Makefile.am: Increment shared lib revision number. I think
4853 sometimes the uninstalled Guile finds the installed shared lib;
4854 Gord says doing this might help. As things turned out, I can't
4855 say whether it does.
4856 * Makefile.in: Regenerated.
4858 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
4859 passing it as the closure argument to scm_boot_guile. (Bill
4862 * ports.c (print_void_port, putc_void_port, puts_void_port,
4863 write_void_port, flush_void_port, getc_void_port, close_void_port,
4864 noop0): Use ANSI prototypes instead of K&R declarations, so the
4865 initialization of void_port_ptob gets aggressively type-checked.
4866 Fix arguments of print_void_port and write_void_port. (Bill

4900 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
4902 * script.c (scm_find_executable): Use prototype-style definition
4903 here; apparently it's not quite right to have const in a prototype
4904 and then use a K&R declaration. I wonder if stuff like this will
4905 go away if we compile with -Wrequire-prototypes, or whatever that
4906 is... (Bernard URBAN)
4908 * scmhob.h: New text from Bernard URBAN.
4910 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4912 * script.c: Don't #define const on hpux. Configure takes care of
4913 this. (Thanks to Larry Schwimmer.)
4915 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
4916 decide whether to #include <unistd.h>, instead of listing a bunch
4917 of systems. Don't #include stdio twice. Removed dyked-out
4918 definition of scm_find_impl_file.
4920 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4922 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
4923 library version info to 1:0.
4924 * Makefile.in: Regenerated.
4926 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

4930 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
4931 throw.c: Update copyright years; these files have been worked on
4932 significantly in 1997, but only had copyright years for 1996.
4933 Also, change name of copyright holder on some from Mikael
4934 Djurfeldt to Free Software Foundation; he has signed papers
4935 assigning the changes to the FSF.
4937 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
4938 reason not to give the user the option.
4940 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
4941 Return #f on end-of-file when scanning table (i.e. when called
4942 with no arguments). Try to catch errors, when we can.
4943 * posix.c (scm_getgrgid, scm_getpwuid): Same.
4945 * script.h (scm_shell_usage, scm_compile_shell_switches): New
4946 external declarations. These are useful.

4950 * posix.c: don't include <sys/select.h> or define macros for
4951 select, since they were not used in this file.
4953 * filesys.c (scm_select): make the fifth parameter microseconds,
4954 not milliseconds. let the fourth parameter be either a real value
4955 or an integer or #f. The first, second and third arguments can
4956 now be vectors: the type of the corresponding return set will be
4958 (set_element, get_element): new static procedures.
4960 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
4962 * strports.c (scm_eval_string): New function.

4970 (scm_pipob): Use it in the initializer here.
4973 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
4974 Use a meaningful error message when signalling an error. For
4975 this, scm_gethost must check h_errno rather than errno.
4977 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
4979 * Makefile.in: Regenerated, using automake-1.1p.

4993 Ensure that shared substrings are handled properly when passed to
4994 a system call or other foreign function. Many thanks to Tim
4996 * symbols.h (SCM_COERCE_SUBSTR): new macro.
4997 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
4998 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
4999 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

5001 scm_strftime), vports.c (scm_make_soft_port), backtrace.c
5002 (scm_display_error_message): use RO macros when strings may be RO.
5003 * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod,
5004 scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir,
5005 scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c
5006 (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c
5007 (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c
5008 (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime,
5009 scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime,
5010 scm_strftime), vports.c (scm_make_soft_port): use
5011 SCM_COERCE_SUBSTR to make sure shared substrings are

5016 * error.c (scm_error): Add newline to error message.
5018 * init.c (scm_init_standard_ports): Doc fix.
5020 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
5022 * dynl-shl.c: Completely replaced with new code from Bernard
5025 * script.c (scm_ice_9_already_loaded): New variable.
5026 (scm_compile_shell_switches): Use it.
5028 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5030 * filesys.c (scm_input_waiting_p): add missing third argument to
5033 * stime.c (scm_localtime): copy the result of localtime before
5034 calling gmtime in case they share a buffer.
5035 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
5038 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5040 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
5042 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
5044 * Makefile.am (check-local): New target, which causes 'make check'
5045 to run gh_test_c and gh_test_repl, with some trivial input.
5046 * Makefile.in: Rgnrtd.
5048 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
5050 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
5053 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
5055 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
5056 sure how this was supposed to work.
5057 (scm_async_click): don't send SCM_TICK_SIGNAL.
5058 (scm_init_async): don't initialize %tick-thunk.
5060 * the following change doesn't affect the Scheme interface:
5061 gc-thunk is called at the end of garbage collection. however it's
5062 no longer implemented by pretending it's a signal.
5064 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
5065 system async corresponding to scm_gc_thunk.
5066 * async.h: declare scm_gc_async.
5067 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
5068 gc-thunk directly, instead of going through a signal handler.
5069 (scm_gc_async): new variable, points to the GC system-async.
5070 (scm_init_async): save the GC async as scm_gc_async instead
5071 of using system_signal_asyncs.
5072 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
5074 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
5076 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
5077 Don't screw up if we're interrupted.
5078 * Makefile.in: Regeneradet.
5080 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
5082 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
5084 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
5085 we're not using AM_INIT_GUILE_MODULE any more.
5086 * Makefile.in: Reneregated.
5088 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
5090 Functions for finding variable bindings, grace à Tim Pierce.
5091 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
5092 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
5094 Get 'make dist' to work again.
5095 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
5096 * Makefile.in: Regenerated, like a surry without a fringe on top.
5098 Changes for reduced Guile distribution: one configure script,
5100 * configure.in, configure: Removed.
5101 * acconfig.h, acinclude.m4: Moved to parent directory, where the
5102 real configure script lives.
5103 * Makefile.in, scmconfig.h.in: Regenerated.
5105 * init.c: #include "script.h", to get prototype for script.c's
5108 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
5110 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
5111 scm_must_malloc, not raw malloc.
5113 * script.c (scm_compile_shell_switches): Dyke out debugging output
5116 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5118 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
5120 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
5121 system has them. Hope this is safe. Previously
5122 sys/timeb.h was included if HAVE_FTIME was defined or if
5123 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
5124 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
5126 * ioext.c (scm_setfileno): add missing third argument to
5127 scm_misc_error call.
5129 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
5131 * eq.c (scm_equal_p): Correctly compare strings of different
5132 varieties. (Thanks to Tim Pierce.)
5134 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
5136 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
5137 #! block comment must occur on a line all by itself.
5139 Move most of the guts of shell command processing into libguile,
5140 so guile.c can be very small (and eventuallly auto-generated. (I
5141 mean, generated mechanically, not self-generated. Hmm.))
5142 * guile.c, script.c, script.h: New source files.
5143 * init.c (scm_boot_guile_1): Call scm_init_script.
5144 * libguile.h: #include "script.h".
5145 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
5146 targets, for new executable.
5147 (libguile_la_SOURCES): Mention script.c.
5148 (modinclude_HEADERS): Add script.h.
5149 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
5150 not dynamic linking is enabled. This is because we're generating
5151 executables now. Move CY_AC_WITH_THREADS call after those, so the
5152 values of cy_cv_threads_libs captures the libs chosen above.
5153 * Makefile.in, configure, aclocal.m4: Regenerated.
5155 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
5156 We don't maintain this interface any more, and it just confuses
5159 * alloca.c: #include <scmconfig.h>, not <config.h>.
5160 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
5161 it'll get included in disties.
5163 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5165 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
5166 be distributed, because they confuse people.
5167 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
5169 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
5171 * configure.in: check for presence of gethostent (not present on
5172 OpenBSD by default).
5173 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
5174 * configure, scmconfig.h.in: Regenerated.
5176 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5178 * backtrace.c (scm_backtrace): Split message string across
5179 newlines properly. GCC is more tolerant of this than other
5182 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
5184 Merge threads directory into libguile.
5185 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5186 threads.h: New source files.

5188 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
5190 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5191 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5192 coop-threads.c.cygnus, coop-threads.h.cygnus.
5193 * configure.in: If we're using threads, include threads.o in
5195 * _scm.h, libguile.h: threads.h lives in this directory now.
5196 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5197 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5198 currently used, but brought along for information's sake.
5199 * ChangeLog-threads: log from old 'threads' directory.
5200 * Makefile.in, configure: Rebuilt.
5202 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5204 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5207 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5209 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5211 Merge GH interface library into libguile.
5212 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
5213 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5214 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5215 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5217 (EXTRA_libguile_la_SOURCES): ... here.
5218 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5219 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5220 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5221 New variables, describing how to build the gh test programs.
5222 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5223 build the test programs, and we probably should have been linking
5224 libguile.la against them all along, to support AIX shared libs.
5225 Add cflags for threads to CFLAGS; add libs for threads to new
5226 variable THREAD_LIBS, used in Makefile.am.
5227 * ChangeLog-gh: log from old `gh' subdirectory.
5228 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5230 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5232 * acconfig.h: Undo change of Apr 9; including the definition of
5233 PACKAGE in the guile headers conflicts with applications' own
5235 * scmconfig.h.in: Regenerated.
5237 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

5244 when PROC is receiving no arguments.
5246 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5248 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5249 have S_IFSOCK. This is the case under Ultrix.
5251 * posix.c (scm_status_exit_val, scm_status_exit_val,
5252 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5253 Ultrix versions of WIFSTOPPED, etc., which assume that their
5254 arguments are lvalues (hmm).
5256 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5258 * eval.c: Doc fixes.
5260 * throw.c: Doc fixes; rearranged.
5262 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
5264 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
5266 * acconfig.h: Added entry for PACKAGE.
5267 * scmconfig.h.in: Regenerated.
5269 Changes to work with automake-1.1n, which has better libtool support.
5270 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5271 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the

5275 * Makefile.in: Rebuild.
5277 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5279 * stime.c (scm_mktime): take an optional zone argument.
5280 (scm_localtime): check putenv return value.
5281 (scm_strftime, scm_strptime): moved from posix.c. move #include
5283 stime.h, posix.h: update prototypes.
5284 (bdtime2c, setzone, restorezone): new static procedures.
5285 (scm_mktime, scm_strftime): use them.
5286 (scm_strftime): don't call mktime before strftime. Use
5287 filltime for return value.
5288 (filltime): convert NULL zname to #f.
5289 (scm_strptime): return a count of characters consumed, not
5290 the remaining string.
5292 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5294 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
5295 (scm_mktime): likewise.
5297 Uncomment localtime and mktime.
5299 * configure.in: add AC_STRUCT_TIMEZONE.
5301 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5303 * stime.c (scm_init_stime): don't define ticks/sec.
5304 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5305 return value problem and is still portable.)
5307 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5309 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5310 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5311 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5312 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5313 cpp_err_symbols.c): Corresponding changes.
5314 * Makefile.in: Regenerated.
5316 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5318 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5319 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5320 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5321 * putenv.c: new file, from sh-utils 1.12.
5323 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5324 since allocation isn't for Scheme objects.
5325 (scm_putenv): copy strings before placing in the environment.
5327 * stime.c (scm_current_time): throw an error if time returns -1,
5328 instead of returning #f.
5329 (scm_get_internal_real_time, scm_get_internal_real_time): use
5330 scm_long2num for return value instead of SCM_MAKINUM.
5332 * stime.h: prototypes updated.
5334 * stime.c (scm_time_in_msec): apparently unused, deleted.
5336 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5338 * configure.in: check for gettimeofday.
5340 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5341 which may be more usefully portable than a gettimeofday interface.
5343 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5345 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5347 * Makefile.in: Regenerated.
5349 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5351 * stime.c (filltime): recovered static procedure.
5352 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5355 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5356 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5358 * posix.c (scm_mknod): split the mode argument into type and perms
5359 arguments, like the extra fields returned by stat.
5361 * fports.c (scm_pipob): set the close, free and print procedures.
5362 (scm_close_pipe): new procedure.
5364 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5365 define them in boot-9.scm
5367 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5369 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5370 wan't defined. Don't include fd.h.
5372 * Previously fd.h was regenerated whenever configure was run,
5373 forcing a couple of files to be recompiled.
5375 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5376 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5377 Check for _fileno as well as _file.
5379 * ioext.c: don't fd.h.
5380 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5383 * Change the stratigy for getting information about errno
5384 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5385 generating lists of symbols during the build process, which will
5386 not always work, include comprehensive lists in the distribution.
5387 To help keep the lists up to date, the "check_signals" and
5388 "check_errnos" make targets can be used.
5390 * configure.in: don't check for a command to extract errno codes.
5391 * Makefile.am: update file lists, remove errnos.list and errnos.c
5392 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5393 check_errnos targets.
5394 (CLEANFILES): remove errnos.c and errnos.list, add
5395 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5396 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5397 * errnos.default: deleted.
5398 * cpp_signal.c: new file.
5399 * cpp_errno.c: renamed from errnos_get.c.
5400 * cpp_err_symbols, cpp_sig_symbols: new files.
5401 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5402 * error.c (scm_init_error): #include cpp_err_symbols instead of
5404 * posix.c (scm_init_posix): don't intern signal symbols. #include
5407 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5409 * strop.c (scm_i_index): allow the lower bound to be equal to the
5410 length of the string, so a null string doesn't always give an error.
5412 * posix.h: new prototypes.
5413 * posix.c (scm_status_exit_val, scm_status_term_sig,
5414 scm_status_stop_sig): new functions, as in scsh. They break down
5415 process status values as returned by waitpid.
5417 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5419 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5420 configure doesn't know about it.
5422 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5424 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5426 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5427 which defines C variables with global linkage.
5429 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5431 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5434 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5436 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5437 has time to check why this doesn't work well with continuations.
5439 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5441 * Fix shell syntax error; some shells won't tolerate
5442 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5444 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5446 * posix.c (scm_uname): throw an error if uname fails instead
5449 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5451 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
5454 * async.c (scm_ints_disabled): definition moved from error.c.
5456 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5458 * acconfig.h: Removed PACKAGE.
5460 * scmconfig.h.in: Regenerated.
5462 * snarf.h: g++ says it's non-portable not to specify the first
5463 argument in a varargs declaration. I introduced the first
5464 argument by using preprocessor conditionals.
5466 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5468 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5469 (scm_freopen): use RO string macros for filename and modes.
5470 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
5472 * posix.c (scm_getgrgid): simplify conversion of name to C string.
5473 (scm_mknod): use RO string macros for path.
5475 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
5476 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5478 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5479 use SCM_ROSTRINGP and SCM_ROCHARS.
5481 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5483 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5486 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5487 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5488 support for byte vectors.
5490 * print.c (scm_iprin1): Limit number of vector elements printed
5491 according to pstate->length.
5493 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5495 * backtrace.c (scm_display_error_message): don't segv if message
5498 * error.h: prototype for scm_error_scm.
5500 * error.c (scm_error_scm): new procedure, reimplements scm-error
5501 in C and uses scm_error.
5503 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5505 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5506 pointer to the Scheme variable read-hash-procedures and intern it
5507 in scm_init_read. Modify scm_read_hash_extend and
5508 scm_get_hash_procedure to use the pointer.
5510 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5512 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5513 (SCM_KEYWORD_STYLE): defined.
5515 * read.c (scm_read_opts): add a keywords option. This isn't a
5516 boolean option, in case someone wants to add support for DSSSL
5518 Setup scm_keyword_prefix symbol.
5519 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5521 I've left keyword support disabled by default, since it doesn't
5522 seem to break the module system and it gives R4RS standard behaviour.
5523 It can be reactivated with (read-set! keywords 'prefix).
5525 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5527 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5528 before constructing arbiter.
5530 * eval.c (scm_m_define): Bugfix: Check that the object is a
5531 closure before setting the procedure property!
5533 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5535 * ports.c: Removed `ungetc-char-ready?'.
5537 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5539 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5540 (idea from Mikael: make it a pair so scm_permanent object only
5542 (scm_read_hash_extend): don't call scm_permanent_object.
5543 (ideas from Mikael): if chr is already in the list, replace its
5544 procedure instead of appending it again. If proc is #f, remove
5546 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5548 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5550 * gdbint.c (gdb_read): update scm_lreadr usage.
5552 * load.h: update prototypes.
5554 * load.c (scm_primitive_load, scm_read_and_eval_x,
5555 scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
5557 * read.h: add prototype for scm_read_hash_extend. Change args for
5560 * read.c (scm_read_hash_procedures): new variable.
5561 (scm_read_hash_extend): new procedure.
5562 (scm_get_hash_procedure): new procedure.
5563 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5564 for extended # processing.
5565 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5566 scm_read_token): remove case_i, sharp arguments. Change callers.
5568 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5570 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5571 (SCM_CASE_INSENSITIVE_P): define.
5573 * read.c: add case-insensitive option to scm_read_opts.
5574 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5575 to determine whether to convert symbol case.
5576 (default_case_i): definition removed.
5577 * read.c (scm_read_token): if case_i, downcase ic before doing
5580 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5582 * configure.in: Added configuration option `guile-debug'.
5583 Configure with --enable-guile-debug if you want a bunch of extra
5584 functions used for debugging when developing Guile.
5586 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5588 * procs.c (make-cclo): New undocumented debugging procedure: Make
5589 compiled closure with internal procedure PROC and length LENGTH.
5590 Only compiled if GUILE_DEBUG is defined.
5592 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5594 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5596 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5598 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5599 with 3 or more args internally to the evaluator.
5601 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5603 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5604 with 3 or more args internally to the evaluator. This is mainly
5605 because we don't want to pass entry and exit points of the
5606 debug support twice, but it also seems to increase the speed of
5607 the evaluator for such calls (e. g. (+ 1 2 3)).
5609 * backtrace.c (scm_display_application): New procedure:
5610 display-application; Set fancy printing parameters individually
5611 for different types of display (backtrace, error, application).
5612 (These should of course be customizable!)
5614 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5615 clear the CHECK-flags.
5617 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5619 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5621 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5623 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5624 from pairs with a GLOC in the car.
5626 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5627 otherwise `symbol-hash' will behave badly.
5628 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5629 we get segmentation fault!
5631 * symbols.c: Added #include "weaks.h". New functions:
5632 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5633 moved to an extraneous library when we split libguile.)
5635 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5637 * filesys.c (scm_stat): stat now takes fport arguments too as
5638 documented in the manual.
5640 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5642 * debug.c (scm_single_step): Bugfix: Call continuation with
5643 scm_call_continuation instead of throwing to it.
5645 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5647 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5648 argument wasn't declared to be optional.
5650 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5652 * stime.c (scm_init_stime): Add feature "current-time".
5654 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5656 * throw.h: prototype for scm_exit_status.
5657 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5658 args to derive an exit status. Allows (quit) to work from a
5660 (scm_exit_status): new function.
5663 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5665 * eval.c (scm_deval): Removed some old code.
5666 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5668 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5671 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5674 * procs.c: Introduce the existent C function scm_thunk_p at the
5675 Scheme level as well.
5677 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5679 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5680 used from C to easily lookup the value of a symbol in the current
5683 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5685 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5686 scm_init_unif in this file. This will also fix a previous problem
5689 * configure.in: Added AM_MAINTAINER_MODE
5691 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5693 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5696 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5698 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5699 source files that are not always included in libguile but should
5700 have their dependencies calculated by automake. This variable is
5701 recognized by automake, no further magic is needed.
5702 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5703 to deal exclusively with *.lo files, as it seems. The *.o files
5704 are built automatically when the corresponding *.lo file gets
5707 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5709 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5712 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5714 * unif.c (scm_array_set_x): minor change to argument error checking.
5716 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5718 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5719 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5720 They should only be included in the library at configure.in's
5722 (libguile_la_LDADD): Include the appropriate .lo files here.
5723 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5724 so we know when to build them (and their .lo bretheren).
5725 * configure.in (LIBLOBJS): New substituted variable. We let
5726 configure decide which .o files to include in LIBOBJS, and then
5727 put the corresponding list of .lo files in LIBLOBJS. The latter
5728 is what we pass to libtool.
5729 * Makefile.in, configure: regenerated.
5731 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5733 * symbols.c (scm_sysintern0): New function. Contains the core of
5734 old scm_sysintern but doesn't take a second value argument.
5735 (scm_sysintern): Now uses scm_sysintern0.
5736 (scm_sysintern_no_module_lookup): Renamed to
5737 scm_sysintern0_no_module_lookup and doesn't take a second value
5738 argument any longer.
5740 * symbols.h (scm_sysintern0: Added declaration.
5742 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5743 scm_sysintern when interning option keys. Otherwise we risk
5744 destroying the values of already interned variables.
5746 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5747 scheme-level boolean (use SCM_NFALSEP).
5749 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5751 (scm_backtrace): New function. (C version of old function from
5752 boot-9.scm) Motivation: Make it possible to display backtraces
5753 without depending on boot-9.scm. (I'm uncertain if this
5754 motivation is good enough...)
5756 * root.h (scm_root_state): Add member the_last_stack_var.
5757 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5759 * root.c (mark_root): Mark scm_the_last_stack_var.
5761 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5764 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5766 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5767 1. mark_lazy_catch didn't mark the smob.
5768 2. Both functions above have standard variants:
5769 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5770 free_lazy_catch --> scm_free0.
5772 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5774 * throw.c (scm_internal_lazy_catch): New function.
5775 (scm_lazy_catch): Rewritten to use it.
5776 (scm_ithrow): Handle the new lazy catch representation.
5777 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
5778 that doesn't have a jmpbuf is a lazy catch clause.
5779 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
5780 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
5781 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
5783 (scm_init_throw): Register the new lazy-catch smob type.
5784 * throw.h (scm_internal_lazy_catch): decl for new function.
5786 * throw.c (scm_internal_catch): Doc fixes.
5788 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
5789 configure.in. Including this might cause problems if applications
5790 that link against libguile include their own copies of alloca, but
5791 if they're using autoconf, they should be adding libguile to LIBS
5792 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
5793 the copy in libguile, and things will be okay. (I think.)
5795 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5797 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
5799 strop.h: move prototypes too.
5801 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5803 * posix.c (scm_init_posix): don't intern EINTR since it's now done
5806 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
5807 etc. I deleted them from filesys.c long ago, but didn't
5808 notice they were here too (although ineffective since
5809 sys/stat.h wasn't included).
5811 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
5813 * eval.c: Don't define alloca in GCC case. gcc will automatically
5814 use __builtin_alloca if appropriate.
5816 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5818 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
5819 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
5820 that values of automatic variables are preserved. See comments
5821 for safe_setjmp for details.
5823 Change from Thomas Morgan:
5824 * variable.c: Include eq.h.
5825 (var_equal): New function.
5826 (variable_smob): Use var_equal as the discriminator for variables.
5828 * throw.c (s_throw): Remove extraneous declaration.
5830 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
5831 * eval.c: Add necessary CPP cruft to support that.
5832 * configure, Makefile.in, scmconfig.h.in: regenerated.
5834 Change from Thomas Morgan:
5835 * procprop.c (scm_procedure_properties): Convert the Scheme
5836 boolean returned by scm_procedure_p into a C boolean before using
5837 it as a condition for SCM_ASSERT.
5838 (scm_procedure_property): Likewise.
5840 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
5841 indications of Unixness.
5844 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5846 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
5848 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5850 * read.c (scm_lreadr): use scm_misc_error to improve one of the
5851 "unknown # object" error messages.
5853 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
5854 (scm_i_index) and declare it static. Add a 'direction' argument
5855 to indicate what way the search should go.
5856 (scm_i_index): throw out-of-range error instead of wrong-type-arg
5858 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
5859 strop.h: remove scm_i_index, scm_i_rindex prototypes.
5861 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5863 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
5865 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
5866 to avoid clash with various scsh forks.
5868 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
5870 The following two changes (ramap.c, throw.c) are motivated by the
5871 apparent unportability of forward declarations of static arrays of
5872 the form `static foo bar[];'.
5874 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
5875 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
5877 * throw.c (scm_throw): Moved above scm_ithrow.
5879 * options.h: Removed the extern declarations of scm_yes_sym and
5880 scm_no_sym since these are static.
5882 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5884 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
5886 * Makefile.am: remove AWK=@AWK@.
5887 Add a rule for generating errnos.list.
5888 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
5890 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
5891 don't extract errnos, just set a variable (avoids the
5892 need to recompile error.c just because configure is run.)
5894 * unif.h: update prototypes.
5895 * unif.c (scm_uniform_array_read,write): change the offset and
5896 length arguments to start and end, for consistency.
5898 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
5900 * ioext.h: update prototypes.
5901 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
5902 scm_read_line_x, it's a more general procedure using an
5903 interface from scsh. read-line and read-line! are now defined
5905 Note that the new read-line trims the terminator
5906 by default, previously it was appended to the returned string. An
5907 optional argument specifies how to process the terminator (scsh
5908 compatible). For the old behaviour: (read-line port 'concat).
5909 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
5910 returns a pair, but is converted to multiple values if the scsh
5913 socket.h: update prototypes.
5914 * socket.c (scm_recvfrom): for consistency with other procedures,
5915 take start and end as separate optional arguments.
5916 (scm_recv, scm_recvfrom): don't allow the second argument
5917 to be a size, only a buffer. Change the scheme names to
5918 recv! and recvfrom!. Don't return the buffer.
5920 * ioext.h, posix.h: move prototypes too.
5921 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
5922 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
5923 "read.h" and "unif.h".
5924 * ioext.c: include "chars.h"
5926 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
5928 * dynl.c: The dynamic linking and module registration functions
5929 are now defined even when dynamic linking is not available for the
5930 host system. Some of their functionality can be done without
5931 dynamic linking; when it's really needed, they throw errors.
5933 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
5935 * configure.in: Only define DYNAMIC_LINKING when one of the system
5936 dependent functions is detected.
5937 * dynl.c (scm_dynamic_func): New function to get the address of a
5938 function in a dynamic object.
5939 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
5940 produced by scm_dynamic_func as the thing to call.
5942 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
5944 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
5945 (scm_register_module_xxx, scm_registered_modules,
5946 scm_clear_registered_modules): New functions.
5948 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
5950 * symbols.c (scm_sysintern): Renamed to
5951 scm_sysintern_no_module_lookup.
5952 (scm_sysintern): New function to take the place of the old
5953 scm_sysintern. It uses the current toplevel lookup closure to give
5954 the symbol its value. This is a temporary hack to put packages
5955 like gtcltk into their own module.
5956 (scm_can_use_top_level_lookup_closure_var): New variable to tell
5957 us whether `scm_top_level_lookup_closure_var' has been initialized
5959 * eval.c (scm_init_eval): Set it.
5961 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5963 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
5964 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
5966 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
5968 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
5969 scm_sys_dup): deleted: FD capability will be added to other
5971 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
5972 scm_fd_free, fd_smob, scm_intern_fd.
5973 (scm_open): renamed from scm_sys_open. Return a port instead of
5974 an FD object. Make the mode argument optional.
5975 (scm_sys_create): deleted, it's just a special case of open.
5976 (scm_init_filesys): move interning of constants O_CREAT etc.,
5977 here (were previously using SCM_CONST_LONG macro).
5978 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
5980 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
5981 include "fports.h" and <stdio.h>
5982 (scm_stat, scm_select): don't support FD objects.
5984 * error.h: adjust scm_syserror_msg prototype.
5985 * error.c (scm_syserror_msg): take an extra argument for errno.
5986 Using the global value didn't always work, since it could be
5987 reset by procedure calls in the message or args arguments.
5989 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
5990 I don't understand why the check was there (and what about the
5993 * strop.c (scm_string_copy): allow shared substrings to be copied.
5995 * unif.h: corresponding change to prototypes.
5996 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
5997 recognize two new optional arguments: offset and length. Allow
5998 the port argument to be an integer (file descriptor, for scsh).
5999 Include <unistd.h> for "read" prototype.
6001 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
6003 * socket.c: don't include filesys.h.
6005 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
6007 * Makefile.am: add AWK=@AWK@ (?)
6009 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
6011 Add a rule to generate errnos.c from errnos.
6012 * error.c (scm_init_error): include errnos.c.
6013 * errnos_cnvt.awk: new file, converts the list of errno codes to
6015 * errnos_get.c: new file.
6016 * errnos.default: new file, contains errnos to try if they can't
6017 be extracted from errno.h.
6018 * configure.in: if using GCC, try and extract errno codes from
6022 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
6024 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
6025 * Makefile.am: Made libguile into a libtool library.
6026 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
6027 Set libtool_libs to indicate that libguile is a libtool library.
6028 See guile/ChangeLog for details.
6029 * .cvsignore: ignore "*.lo", the libtool library objects.
6031 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
6033 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
6034 use htons in getservbyport argument.
6036 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
6038 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
6039 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
6042 * objprop.c (scm_object_property): No need to take the CDR of the
6043 value returned by scm_object_properties, since Aug 20 change.
6045 * configure.in: When checking for struct linger, #include
6046 <sys/types.h> as well as <sys/socket.h>. I've never known
6047 <sys/types.h> to cause any portability problems, and Solaris's
6048 <sys/socket.h> needs it.
6049 * configure: Rebuilt.
6051 I think the Sun compiler has chosen a perverse way to interpret
6052 ANSI declarations combined with K&R definitions. We'll
6053 appease it a little bit. But when it invades France, we fight.
6054 * print.c (scm_iprlist): Change 'tlr' argument to an int.
6055 * print.h (scm_iprlist): Here too.
6056 * numbers.c (scm_divbigdig): Change definition to match
6057 declaration in numbers.h.
6058 * unif.c (scm_makflo): Change definition to match declaration in
6061 * init.c (scm_boot_guile): Don't return the value of
6062 scm_boot_guile_1. This function doesn't return a value;
6063 scm_boot_guile_1 doesn't return a value (or return at all).
6065 * eval.c (unmemocopy): Add a semicolon to appease the Sun
6068 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
6069 compile. I have a feeling this function is a bad idea anyway ---
6070 one should always test for features, not systems.
6072 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
6073 semicolons. Only pure luck kept this from being noticed earlier.
6075 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
6077 * socket.c (scm_recvfrom): Added missing semicolon.
6079 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
6081 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
6082 the buffer and start and end positions for scsh networking
6085 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
6087 * configure.in: Revert previous change to this file; the problem
6088 is due to transient automake weirdness.
6089 * configure: Rebuilt.
6091 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
6092 PLUGIN/guile.libs. configure generates the latter from the former.
6093 * Makefile.in: Rebuilt.
6095 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
6096 need this if we install scripts, like guile-snarf.
6097 * configure: Rebuilt.
6099 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
6101 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
6103 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
6105 * socket.c (scm_addr_vector): fix faulty scm_listify.
6107 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
6109 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
6110 style block comment is no longer considered an error.
6112 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
6114 * PLUGIN/guile.libs.in: New file.
6115 * PLUGIN/guile.libs: Removed from repository.
6116 * configure.in: Create PLUGIN/guile.libs from
6117 PLUGIN/guile.libs.in. This is for including additonal libraries
6118 needed for dynamic linking.
6119 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
6120 instead of PLUGIN/guile.libs.
6122 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
6124 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
6126 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
6127 occurrences of the given element from the list, not just the
6128 first. This is how the Emacs Lisp functions behave, how the
6129 analogous Common Lisp functions behave, and (I believe) how the
6130 older Maclisp functions worked. I realize that this change may
6131 break code, but it seemed better to break it before the Guile
6134 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
6135 Their prototypes were already present in gc.h, but they weren't
6137 (scm_init_storage): Initialize scm_protects.
6138 * root.c (scm_protects): New element of scm_sys_protects.
6140 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
6142 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6144 * libguile.h: Added #include "libguile/net_db.h".
6146 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
6147 30 change. That file is only meant for communication between the
6148 configuration process and load.c. If code linked against libguile
6149 wants to get at the paths mentioned in libpath.h, it can call
6150 functions declared in load.h.
6152 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6154 * libguile.h: Removed #include "libguile/fdsocket.h"
6156 * net_db.c: Added #include <sys/socket.h>.
6158 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
6160 * filesys.c (scm_input_waiting_p): use select in preference to
6161 FIONREAD, since the latter doesn't detect EOF.
6162 Throw error if neither select nor FIONREAD available.
6164 * socket.c (scm_connect): take a port, not a fd object.
6165 (scm_fill_sockaddr): throw an error if fam is not recognised.
6166 (scm_bind): use scm_fill_sockaddr.
6167 (scm_listen): take a port, not a fd object.
6168 (scm_accept): take and return a port. return #f in the car if
6169 address can't be got
6170 (scm_sock_fd_to_port): new procedure.
6171 (scm_socket): use scm_sock_fd_to_port.
6172 (scm_addr_vector): throw error if unrecognised address type.
6173 take an extra argument with the calling procedure name.
6174 (scm_getsockname): take a port. return #f if address can't be got.
6175 (scm_getpeername): take a port. return #f if address can't be got.
6176 (scm_recvfrom): take a port. return #f for address component if can't
6178 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6179 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6181 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6183 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6184 use separate data pointers, to allow them to be designed
6185 independently and reused.
6186 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6187 Renamed from catch_body, catch_handler, and uncaught_throw; made
6189 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6191 (scm_catch): Use the above.
6192 (scm_throw): Don't bother printing a message for an uncaught
6193 throw; we establish a default handler in init.
6194 * throw.h (scm_internal_catch): Prototype updated.
6195 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6197 (struct scm_body_thunk_data): New structure, used as data
6198 argument to scm_body_thunk.
6199 * init.c (struct main_func_closure): New structure, packaging up
6200 the data to pass to the user's main function.
6201 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6202 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6203 scm_internal_catch to establish a catch-all handler, using
6204 scm_handle_by_message. This replaces the special-case code in
6206 (invoke_main_func): Body function for scm_internal_catch; invoke
6207 the user's main function, using the main_func_closure pointer to
6208 decide what to pass it.
6209 * root.c (struct cwdr_body_data): Remove handler_proc member.
6210 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6211 (cwdr_handler): Removed.
6213 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6215 * socket.h (SCM_P): update bind prototype.
6216 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6217 include "feature.h".
6218 (scm_socket): return a port, not a file descriptor object.
6219 include "fports.h" and <unistd.h>
6220 (scm_bind): take a port, not a file descriptor object.
6221 take an extra argument for address args.
6223 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6224 INADDR_NONE, INADDR_LOOPBACK.
6226 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6228 * init.c: include net_db.h and not fdsocket.h.
6229 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6231 * Makefile.am: corresponding changes.
6232 * socket.h: renamed from fdsocket.h, fix names.
6233 * net_db.h: renamed from socket.h, fix names.
6234 * socket.c: renamed from fdsocket.c.
6235 remove _sys from procedure names.
6236 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6237 add "socket" to features list.
6238 * net_db.c: renamed from socket.c.
6239 remove _sys from procedure names.
6240 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6241 add "net-db" to features list.
6242 include "net_db.h". don't include <sys/socket.h> or
6245 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6247 * tags.h (scm_tags): Removed comma at end of last enumerator.
6249 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6251 Don't use GCC extensions to allocate space for debugging frames.
6252 (Here he goes again! Why do we put up with this?!)
6253 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6254 an scm_debug_info structure, not an in-line array of them. Add
6255 'info' member, to say how many vect elements we've used, for eval
6257 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6258 a new variable debug_info_end to mark the end of vect, instead of
6259 the address of the 'info' pointer itself.
6260 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6261 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6262 (SCM_APPLY): Explicitly allocate space for debug.vect.
6263 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6264 * stacks.c: Adjusted for new debug frame structure.
6265 (RELOC_INFO, RELOC_FRAME): New macros.
6266 (stack_depth, read_frames): Use them, and new scm_debug_frame
6267 element 'info', instead of magically knowing that eval frames have
6268 an info pointer sitting after vect.
6269 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6271 (scm_init_stacks): Formatting tweaks.
6273 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6275 Give GCC more control flow information, so it can be sure that
6276 variables aren't used uninitialized.
6277 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6278 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6279 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6280 scm_misc_error): Tell GCC that these functions never return.
6281 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6282 out the field type, call abort if SCM_ASSERT returns, to placate
6284 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6285 scm_wta ever returns. We can't handle this case anyway, and this
6286 gives the optimizer more information.
6287 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6288 scm_wta ever returns.
6290 In some cases, the code is fine, but GCC isn't smart enough to
6291 figure that out; this usually happens when one variable is only
6292 initialized and used when a particular condition holds true, and
6293 we know that condition will never change within a given invocation
6294 of the function. In this case, we simply initialize the variables
6295 to placate the compiler, hopefully to a value which will cause a
6296 crash if it is ever actually used.
6297 * print.c (scm_iprin1): Initialize mw_pos.
6298 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6299 * throw.c (scm_ithrow): Initialize dynpair.
6300 * unif.c (scm_uniform_vector_ref): Initialize cra.
6301 * struct.c (init_struct): Initialize prot.
6302 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6304 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6305 if EXPR contains no expressions.
6307 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6309 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6310 cause an infinite loop (???). So much for the algebraic
6311 equivalency of variable-sized arrays and alloca...
6313 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6315 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6316 a SCM boolean, not a C boolean.
6318 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6320 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6321 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6322 rules for raising scm_mtrigger. Previously, unfortunate but not
6323 unlikely circumstances could result in almost constant invokation
6324 of the gc. Now, this situations should be less likely, but they
6325 are not prevented completely.
6327 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6329 * numbers.c (scm_fuck): Procedure removed; looks like old test
6331 * numbers.h: Prototype removed.
6333 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6335 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6336 array to a pointer, to match my Nov 21 change in eval.c.
6338 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6340 * libguile.h: Added #include "libguile/backtrace.h", #include
6341 "libguile/stacks.h".
6343 * strings.c (scm_string scm_make_string scm_string_ref
6344 scm_string_set_x scm_string_equal_p scm_string_append):
6345 Bugfix according to scm patch from Aubrey Jaffer:
6346 Corrected long-standing
6347 (not (eqv? (integer->char 128)
6348 (string-ref (make-string 1 (integer->char 128)) 0)))
6349 bug found by John Kozak <jk@noontide.demon.co.uk>.
6351 * strports.c, strports.h: Make scm_eval_0str return the value of
6352 the last expression evaluated (previously, it returned void).
6354 * strports.c, strports.h: New function: scm_read_0str. Does what
6357 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6359 * simpos.c (scm_getenv): return #f if string can't be found in the
6360 environment instead of throwing an exception, for compatibility
6361 with numerous other systems.
6363 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6365 * Makefile.am (.c.x): Use guile-snarf.
6366 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6368 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6370 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6372 * backtrace.c (scm_display_error_message): Made non-static, and
6373 renamed from display_error_message.
6374 * backtrace.h (scm_display_error_message): Added extern decl.
6375 * throw.c (uncaught_throw): Use it to display the error message.
6377 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6379 * inet_aton.c: Use #if 0, not #ifdef 0.
6381 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6383 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6384 to convert the returned value.
6385 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6386 the offset argument.
6388 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6390 Add new interface to catch/throw, usable from C as well as
6392 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6393 (scm_internal_catch): New function, replaces...
6394 (scm_catch_apply): Deleted.
6395 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6396 mechanism which is a bit more code, but can be used nicely from C
6397 and implement the Scheme semantics as well.
6398 (scm_internal_catch): This is the replacement; it's named after
6399 the analogous function in Emacs.
6400 (scm_catch): Reimplemented in terms of the above.
6401 (struct catch_body_data, catch_body, catch_handler): New
6402 functions, used by scm_catch.
6403 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6404 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6405 support for new cwdr.
6407 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6410 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6412 * acconfig.h: Added DYNAMIC_LINKING symbol.
6413 * configure.in: Add option and checks for dynamic linking.
6414 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6415 dynl.h: New files for dynamic linking support.
6416 * Makefile.am (libguile_a_SOURCES):
6418 (modinclude_HEADERS): Added "dynl.h".
6419 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6421 * init.c (scm_boot_guile_1): Call
6422 scm_init_dynamic_linking to initialize dynamic linking support.
6424 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6426 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6427 (as we Schemers say). It needs to be global, so that I can tweak
6428 it for the proper operation of unexec.
6429 (scm_boot_guile_1_live): New variable, see above.
6431 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6433 * guile-snarf.sh: Removed.
6434 * PLUGIN/guile.libs: Added dependency for -lm.
6435 * acinclude.m4: Renamed from aclocal.m4.
6436 * PLUGIN/greet: Removed.
6437 * Makefile.am, aclocal.m4: New files.
6438 * configure.in: Updated for Automake.
6440 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6442 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6443 and not top_level_lookup_thunk_var.
6445 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6447 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6449 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6451 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6452 Scheme function, instead of syntax. Single argument is now a
6455 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6457 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6458 scm_ra_divide): Properly terminate statements passed as arguments
6459 to IVDEP macros. (Thanks to Bernard Urban.)
6461 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6462 with non-constant sizes. (Thanks to Bernard Urban.)
6464 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6466 It's an "eval closure", not an "eval thunk." A thunk is a
6467 function of no arguments.
6468 * root.h (struct scm_root_state): Renamed
6469 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6470 (scm_top_level_lookup_closure_var): Renamed from
6471 scm_top_level_lookup_thunk_var.
6472 * root.c (mark_root): Uses changed.
6473 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6474 * init.c (scm_start_stack): Uses changed.
6475 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6476 Change scheme-visible name to *top-level-lookup-closure* from
6477 *top-level-lookup-thunk*.
6479 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6481 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6482 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6484 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6486 * gc.c (struct scm_heap_seg_data): Doc fixes.
6488 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6489 sweeping. Then, prepend each segment's free cells to its
6490 freelist, rather than wiping out the old value. (Thanks to Marius
6493 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6494 scm_check_freelist, scm_debug_newcell): New functions and
6495 variables, for debugging freelist problems.
6496 * pairs.h (SCM_NEWCELL): New debugging version added.
6497 * gc.h (scm_debug_newcell): Added extern declaration, used by
6498 debugging version of SCM_NEWCELL.
6500 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6502 On some systems <libc.h> conflicts with <unistd.h>, and should not
6503 be #included at all.
6504 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6505 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6506 * configure.in: Call it.
6507 * posix.c, filesys.c: Use its results to decide whether or not to
6509 * configure, scmconfig.h.in: Rebuilt with autoconf and
6512 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6514 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6515 pointer to the stdio stream before calling scm_setbuf0, so the
6516 latter will be able to retrieve it. I'm surprised this didn't
6517 segfault earlier. (Thanks to Christopher Lee.)
6519 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6521 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6524 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6526 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6527 number of stack narrowing specifier pairs. The first specifier in
6528 a pair controls inner border, the second the outer border. A
6529 number means cut that number of frames, a procedure object means
6530 cut until that object is found in operator position in a frame.
6532 * root.c (cwdr): Bugfix.
6534 * read.c: Recording of positions disabled by default.
6536 * procs.c (scm_closure_p): New function.
6538 * posix.c (scm_tmpnam): New function.
6540 * load.c: Added #include "throw.h".
6541 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6544 * load.c, load.h (scm_read_and_eval_x): New function.
6546 * eval.c: Renamed debug option "deval" to "debug".
6548 (scm_eval_x): `eval!' is no longer accessible from the scheme
6549 level. Motivation: We can't allow operations which introduce
6550 glocs into the scheme level. Guile's type system can't handle
6551 these as data. Use `eval' or `read-and-eval!' as replacement.
6553 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6554 SCM_CONSP since this is a macro!; Set vframe.prev to
6555 scm_last_debug_frame instead of 0. In this way we can look
6556 "above" the virtual start stack frame if we wish.
6557 (scm_debug_hang): New function: Useful for debugging Guile in
6558 certain tricky situations. Will probably be removed later...
6560 * debug.h: Changed semantics of debug option "backtrace". This
6561 option now only indicates whether we want automatic backtrace at
6564 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6566 * ports.c: #include "filesys.h"
6567 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6569 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6570 Motivation: This is system specific code which is related to file
6571 I/O. It also may use select. Added code by Gary Houston to
6572 detect presence of character in stdio buffers.
6574 * libguile.h: #include "libguile/libpath.h"
6576 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6577 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6578 SCM_SITE_DIR; Install libpath.h among the other include files.
6580 * load.c, load.h (scm_sys_package_data_dir): New function.
6582 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6584 * stacks.h: Bugfix: Don't use tail-array length field as stack
6585 length field! This screwed GC.
6587 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6589 * _scm.h: Added #ifndef around definition of macros min and max.
6591 * __scm.h: Added hooks for threads to plugin to in ints protection
6592 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6593 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6594 the main code in these macros duplicated and spread over multiple
6595 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6596 SCM_THREAD_SWITCHING_CODE.
6598 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6600 * snarf.h: New file.
6601 * guile-snarf.sh: New file.
6602 * Makefile.in (inner_h_files): Added snarf.h
6603 (ancillary, install, uninstall, distclean): Added actions for
6605 (.c.x): Use guile-snarf.
6606 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6607 (gen_c_files): Note that these depend on guile-snarf.
6608 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6609 now in "snarf.h". Added #include "snarf.h" to get them.
6610 * libguile.h: Added #include "snarf.h".
6611 (Patches applied and tweaked by Jim Blandy.)
6613 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6615 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6616 standards suggest against providing prototypes for system
6617 functions. Thanks to Greg Troxel.
6619 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6621 * strports.c (scm_eval_0str): New function.
6622 #include "read.h", to get prototype for scm_read.
6623 * Makefile.in (strports.o): Update dependencies.
6624 * strports.h: New prototype.
6626 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6627 scheme name from "int?" to "integer?". It seems to do the job.
6628 * numbers.h: Rename prototype too.
6629 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6632 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6633 scm_num_eq_p): Rename these according to R4RS conventions: call
6634 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6635 to making libguile R4RS compliant without ice-9...
6637 * load.c (scm_sys_search_load_path): Search for files under all
6638 extensions listed in the %load-extensions variable. If FILENAME
6639 is absolute, return it unchanged, without searching the load path.
6640 (scm_loc_load_extensions): New variable, pointing to
6641 %load-extensions' value cell.
6642 (scm_init_load): Initialize it, and the value it points to.
6643 (scm_primitive_load_path): Improve error reporting.
6645 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6646 of new Scheme variable %load-hook.
6647 (scm_primitive_load): Apply %load-hook to filename.
6649 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6651 * configure.in: add tests for figuring out whether buffered data
6652 is available in a FILE structure, which is needed by char-ready.
6654 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6657 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6658 exceptions using misc_error instead of syserror. It seems a bit
6659 odd to throw an exception if a string can't be found in the
6660 environment, but it's consistent with open-file, stat etc.
6661 (simpos.h): remove sys_ from getenv.
6663 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6664 occurs, throw an error instead of returning errno. Return value
6666 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6668 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6670 * filesys.c (scm_stat2scm): derive file type and permissions from
6671 the stat mode and append them to the returned vector.
6672 There isn't much overhead in doing this and it avoids the need to
6673 work with S_IRUSR et al. in Scheme.
6674 Define symbols scm_sym_regular etc.
6675 (scm_init_filesys): don't intern S_IRUSR etc.
6677 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6678 and s_primitive_load_path.
6680 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6682 * error.h: don't declare error symbols. prototype for scm_misc_error.
6684 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6687 * error.c: use SCM_SYMBOL to set up error keys.
6688 scm_misc_error: new procedure.
6690 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6692 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6693 between `#!' and `!#' is ignored.
6694 (skip_scsh_block_comment): New function.
6696 * feature.c (scm_set_program_arguments): New argument, FIRST.
6697 * feature.h: Update prototype.
6698 * init.c (scm_boot_guile_1): Pass new argument to
6699 scm_set_program_arguments.
6701 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6703 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6704 (scm_boot_guile): Call scm_set_program_arguments here, later than
6705 the old initialization.
6707 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6708 initialization procedure.
6709 - Delete in, out, err arguments; there are other perfectly good
6710 ways to override these when desired.
6711 - Delete result argument; this function shouldn't ever return.
6712 - Rename init_func argument to main_func, for less confusion.
6713 - Delete boot_cmd argument; main_func is more general.
6714 -Add 'closure' argument, to help people pass data to main_func
6715 without resorting to global variables.
6716 - Abort if reentered; don't bother returning an error code.
6717 - Call scm_init_standard_ports to set up the default/current
6718 standard ports; no need to pass them to scm_start_stack.
6719 - Remove code to evaluate the boot_cmd, and start the repl; let
6720 the user do something like that in main_func if they want.
6721 - Remove code to package up a return value; main_func can do any
6723 - Call exit (0), instead of returning.
6724 (scm_start_stack): Don't initialize the I/O ports here; that's
6725 weird. Delete in, out, err arguments. Move guts to
6726 scm_init_standard_ports, scm_stdio_to_port.
6727 (scm_init_standard_ports): New function, to set up current and
6728 default standard ports.
6729 (scm_start_stack, scm_restart_stack): Make these static.
6730 * init.h (scm_boot_guile): Adjust declaration.
6731 (scm_start_stack, scm_restart_stack): Remove externally
6732 visible declarations for these.
6733 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6735 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6736 written out several times in scm_start_stack.
6737 * fports.h: New declaration for the above.
6739 * feature.c (scm_set_program_arguments): New function.
6740 * feature.h: New declaration for the above.
6742 * ports.c: Formatting tweak.
6744 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6746 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6747 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6748 for obtaining the address of a car or cdr field. Motivation:
6749 &SCM_CXR make assumptions about the internal structure of the
6752 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6753 Motivation: see SCM_CXRLOC.
6755 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6756 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6757 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6758 Motivation: Safer use. Some other macros are defined in terms of
6759 these operations. If these are defined using the SCM_SETCXR
6760 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6761 to inefficiency and an <e1> with side-effects could potentially
6762 break. Also, these particular operations are heavily utilized in
6763 the garbage collector. In unoptimized code there will be a
6766 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6767 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6768 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
6769 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
6770 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
6771 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6772 vports.c: Cleaned up use of pairs: Don't make any special
6773 assumptions about the internal structure of selectors and
6774 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6775 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
6776 (Among other things, this change makes it easier to build Guile
6777 with certain compilers which have problems with casted lvalues.)
6779 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6781 * stacks.c: Improve selection of relevant stack frames when making
6782 a stack object. Introduce one level of indirection in the stack
6783 object to make it possible to "narrow" to a certain region of the
6784 stack. This facilitates making use of more clever algorithms (not
6785 implemented) for selecting relevant frames and gives a cleaner
6786 design since selection of frames can be done independently of
6787 extraction of frames from the real stack.
6788 (scm_stack_id): Also take #t as argument which means look at
6791 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
6792 Turn n_tail into an integer directly representing current number
6793 of frames in stack. Add field tail.
6795 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
6797 * debug.c (scm_make_memoized): Made it available at scheme level.
6798 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
6799 SCM_NIMP before applying heavier predicates in argument checking.
6800 (scm_local_eval): Also take memoized object as argument.
6802 * backtrace.c (scm_display_error): Just a safety measure: Stacks
6803 aren't created with zero length, but should such a strange
6804 creature suddenly turn up...
6806 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
6808 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
6809 `del', for the sake of C++ compilers. (Patch applied by JimB.)
6811 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
6813 * variable.c (scm_make_variable): Make the name hint optional, as
6815 (anonymous_variable_sym): Renamed from variable_sym. All uses
6818 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
6819 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
6820 of scm_primitive_load_path was also changed to
6821 "primitive-load-path", from "%try-load-path". Callers changed.
6822 We'd like to respect the convention that a function named
6823 "try-mumble" should behave just like the function called "mumble",
6824 but return #f instead of signalling some error.
6825 * load.h: Rename prototypes.
6827 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6829 * print.c (make_print_state, grow_print_state), print.h: Modified
6830 the print state representation: Don't use a tail array for
6831 recording of circular references. Resizing of the print state
6832 structure invalidates the print state pointer. To avoid passing
6833 around an indirect print state reference to all printing
6834 functions, we instead let the print state reference a resizable
6837 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
6839 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
6840 Don't crash when passed an improper list terminated by a
6841 non-immediate value.
6843 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
6845 Allocate data for structures on an eight-byte boundary, as
6846 required by the tagging system.
6847 * struct.c (alloc_struct): New function.
6848 (scm_make_struct, scm_make_vtable_vtable): Call it.
6849 * struct.h (scm_struct_n_extra_words): Bump to 3.
6850 (scm_struct_i_ptr): New "field".
6851 * gc.c (scm_gc_sweep): When we need to free the data, use the
6852 information stored by alloc_struct to find the beginning of the
6853 block allocated to the structure, so we can free it.
6855 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6857 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
6860 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
6861 (scm_debug_info): New member: id.
6863 * stacks.c: Stacks are now represented as structs; Stacks have an
6864 id given to them by `start-stack'.
6865 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
6867 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
6868 Changed stack representation.
6870 * debug.c (scm_procedure_name): Try procedure property `name' for
6871 compiled closures aswell.

6877 objects. (Earlier, only closures were recorded.)
6879 * procprop.h: Added declaration of scm_i_name.
6881 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
6882 (scm_make_gsubr): Record names of compiled closures.
6884 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6886 * debug.c, debug.h: Removed obsolete code.
6888 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
6889 stacks.c: Renamed regs --> scm_contregs.
6891 * print.c (scm_free_print_state): Cleanup print state before
6892 returning it to pool. It is better to do it here than in
6893 scm_prin1 since scm_prin1 is called often.
6895 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
6896 s_set_source_property_x): Check that first argument is a pair or a
6899 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
6900 scm_i_line, scm_i_column and scm_i_breakpoint global.
6902 * init.c: Added #include "backtrace.h" and #include "stacks.h".

6915 * symbols.c (scm_sym2ovcell): Fixed documentation.
6917 * _scm.h (min, max): Added.
6919 * async.c: Moved `min' macro to _scm.h.
6921 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
6922 SCM_BACKTRACE_INDENT.
6924 * eval.c: Added new debug options `maxdepth' and `indent'.

6933 * print.h: Added declarations for scm_make_print_state,
6934 scm_free_print_state.
6936 * debug.c (scm_m_start_stack): New acro.
6938 * debug.h: Small cleanup.

6963 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
6964 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
6965 declare functions with prototypes. (Patch thanks to Marius
6968 More prototype-related changes from Marius Vollmer:
6969 * gdb_interface.h: Wrapped header file in #ifdef/#endif
6970 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
6971 * ports.h (ptobfuns): Added prototypes. This means some casting in
6973 * fports.c: Added casts for initializations, since the functions
6974 are defined to take FILE * as their stream argument, not SCM.
6975 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
6976 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
6977 to `char *str_data' to conform to prototype.
6979 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6981 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
6983 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
6985 * stime.c, stime.h: use SCM_P method.
6987 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6989 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
6990 be given at least two arguments. Insist that lst's last element
6991 be a list, but don't make any requirements of its predecessors.
6993 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6995 * eval.c (scm_nconc2last): Revert last change; there seems to be
6996 other stuff going on here.
6998 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7000 * eval.c (scm_nconc2last): Make sure that each element of lst
7001 (which is a list of argument lists, except for the tail) is a
7002 proper list, i.e., finite and terminated by '().
7004 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
7006 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
7009 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
7010 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
7013 * vectors.c (scm_make_vector): Fill vectors with the undefined
7014 value, to help make Guile Scheme code more portable to other
7017 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
7018 * symbols.h, tags.h: Doc fixes.
7020 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
7022 * async.c (scm_take_signal): Doc fixes.
7024 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
7026 * numbers.c (scm_divbigint): When the remainder is zero, we don't
7027 want to subtract it from the modulus; we just want to leave it
7030 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
7032 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
7035 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
7037 * throw.c (scm_catch_apply): Finished implementation of
7040 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
7042 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
7044 (scm_init_filesys): set "i/o-extensions" feature.
7047 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
7049 * Makefile.in (root.o): Correct dependencies.
7051 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
7053 * Makefile.in: Added dependency entry for root.o.
7055 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
7056 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
7058 * init.c (scm_start_stack): Set initial root continuation number
7061 * procs.c: New function: scm_thunk_p.
7063 * procs.h: Added declarations of scm_thunk_p.
7065 * root.c: Renamed `call-with-new-root' -->
7066 `call-with-dynamic-root'.
7067 (cwdr): Removed allocation of new root state. This should be done
7068 separately by use of scm_make_root.
7069 (scm_apply_with_dynamic_root): New function: Does what it
7070 sounds like. Needed when spawning threads.
7072 * root.h: Added member last_debug_frame to root state.
7073 Added #include "libguile/debug.h"
7075 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
7076 arguments. The motivation is that code in root.c needs catch
7077 functionality, and we want to avoid code duplication.
7078 New functions: scm_catch, scm_lazy_catch. These are wrappers for
7079 scm_catch_apply. scm_lazy_catch is intended to introduce catch
7080 handlers that run without popping the stack into the dynwind
7083 * throw.h: Added prototypes for scm_catch_apply and
7086 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7088 * root.h (scm_root, scm_set_root): Decouple thread support details
7089 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
7090 SCM_SET_THREAD_LOCAL_DATA.
7092 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
7093 and tortoise scanning loop.
7095 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
7097 * Makefile.in: Rebuild dependencies.
7099 * libguile.h: #include "libguile/print.h" before "smob.h", since
7100 the latter uses the print_state structure.
7102 * throw.c (scm_ithrow): Use the correct variable when checking to
7103 see if a given element of scm_dynwinds is a valid catch.
7105 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
7106 structure, abort; don't just silently ignore the garbage.
7108 * _scm.h: #include "print.h" here, since it seems to be used just
7110 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
7111 strports.c, unif.h: Don't #include "print.h".
7113 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7115 * feature.h (scm_loc_features): Removed external declaration.
7116 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
7118 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7120 * feature.c (scm_init_feature): Added threads feature (needs to be
7121 initialized here, since features doesn't exist when
7122 scm_init_threads is called).
7124 * libguile.h: Added #include "libguile/../threads/threads.h".
7125 (This is a kludge to get thread support working. This should be
7128 * configure.in, acconfig.h: Added flags for thread support.
7130 * scmsigs.c: Define `signal' to be `pthread_signal' if using
7133 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
7134 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
7137 * _scm.h: Added conditional #include "threads.h"
7139 * __scm.h (SCM_ASYNC_TICK): Added call to macro
7140 SCM_THREADS_SWITCHING_CODE.
7142 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
7143 allocate the basic dynamic root object.
7144 (scm_boot_guile): Added call to scm_init_root.
7146 * root.c, root.h: Added root smob.
7147 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
7148 functions: Implements dynamic roots mostly according to spec in
7149 SCM manual. Main difference is that the second argument is a
7150 throw handler rather than an error "thunk".
7152 * root.h: Added declaration of scm_init_root.
7154 * root.c: Added #include "genio.h", #include "smob.h", #include
7155 "pairs.h", #include "throw.h", #include "dynwind.h", #include
7157 (scm_init_root): Added #include "root.x".
7159 * throw.c: Added #include "stackchk.h"
7160 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
7161 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
7162 can be used in scm_call_with_new_root; Added reenabling of stack
7163 checking when catching a throw.
7165 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
7167 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
7169 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
7170 element is not found, as per R4RS.
7172 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7174 * list.c: Doc fixes throughout.
7176 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7178 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7179 declare the char * to be const. Avoids a warning in rgx.c.
7181 * ports.h: spelling fix.
7183 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7186 * load.c (scm_sys_try_load_path): throw an error if file not found
7187 (like it says it in NEWS).
7189 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7191 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7192 PROPS slot to '(), not #f; it's an empty alist.
7194 * throw.h, throw.c: Use SCM_P instead of #if hair.
7196 Remove special support for uncaught throws; see throw.c for
7198 * throw.c (uncaught_throw): New function.
7199 (scm_ithrow): Call uncaught_throw if we don't find a throw
7200 target; don't mess with scm_bad_throw_vcell.
7201 (scm_bad_throw_vcell): Variable deleted.
7202 (scm_init_throw): Don't initialize it.
7204 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7207 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7209 * numbers.c (scm_istr2int): If the number is short (as most
7210 numbers are), just call scm_small_istr2int to deal with it.
7211 (scm_small_istr2int): New function, created by un-#ifdefing the
7212 non-bignum version of scm_istr2int and renaming it.
7214 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7216 * load.c (scm_sys_try_load): don't check whether value returned
7217 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7218 Change the Scheme name from %try-load to primitive-load.
7220 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7221 Can avoid passing a message, allowing it to be derived in the
7222 error handler (e.g., if we want to throw to the key both from
7225 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7227 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7228 references now have a new appearance which is more compact and
7229 also gives a clue about what the target of the reference is.
7230 By setting parameters in the print state, more fancy printing can
7231 be achieved. This is used by the (not yet commited) backtrace
7234 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7236 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7239 * print.c: Added #include "struct.h". Removed function
7242 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7243 scm_iprin1. Removed prototype for scm_prlist.
7245 * arbiters.c (prinarb),
7246 async.c (print_async),
7247 debug.c (prindebugobj, prinmemoized),
7248 eval.c (prinprom, prinmacro),
7249 filesys.c (scm_fd_print, scm_dir_print),
7251 mallocs.c (prinmalloc),
7252 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7253 smob.h (scm_smobfuns),
7254 srcprop.c (prinsrcprops),
7256 unif.c, unif.h (scm_raprin1, rapr1),
7257 variable.c (prin_var): Changed argument `int writing' to
7258 `scm_print_state *pstate'.
7260 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7261 that it will be called before scm_init_print.
7263 * print.c (scm_prin1): Print states are now allocated when calling
7264 scm_prin1 and then passed around to all printing functions as an
7265 argument. A cache `print_state_pool' enables reuse of print
7267 (scm_make_print_state): New function.
7268 (scm_iprin1): Adaption to print states.
7269 (scm_iprlist): An initial "hare and tortoise" scan brings down
7270 time complexity to O (depth * N). (Better time complexity will be
7271 achieved when the printing code is completely rewritten.)
7273 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7275 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7276 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7277 it gets done whether or not the cache variable has a value.
7279 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7281 Distinguish #f and ().
7282 * __scm.h: #undef SICP.
7283 * pairs.h (SCM_EOL): Delete this definition, equating it with
7285 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7286 the value it used to have. Doc fixes, too.
7288 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7290 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7291 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7292 Lord's implementation of structs, allowing for tail arrays as
7293 described in the manual. Also fixed some bugs. (Both the interface
7294 and the implementation should be improved.)
7296 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7298 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7299 People who whish to see the source can do `(print-enable 'source)'.
7300 Removed #ifdef DEBUG_EXTENSIONS.
7302 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7304 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7305 integer (assuming for now accepting an integer is a good thing).
7307 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7308 %S will be used instead for write'ing arguments.
7310 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7311 asserts. fix a few other asserts.
7312 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7313 scm_uniform_vector_ref, scm_array_set_x,
7314 scm_dimensions_to_unform_array): change args in
7315 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7316 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7317 scm_substring_fill_x): likewise.
7318 gsubr.c (scm_gsubr_apply): likewise.
7319 eval.c (SCM_APPLY): likewise.
7321 * eval.c (4 places): replace scm_everr with lgh_error or
7324 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7325 scm_memory_error): new procedures.
7326 scm_everr: deleted. can use scm_wta, dropping first two args.
7327 scm_error: convert NULL subr to SCM_BOOL_F.
7329 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7332 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7335 * error.c, error.h: new error keys: scm_arg_type_key,
7336 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7338 scm_wta: reimplement using lgh_error instead of scm_everr.
7340 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7342 * gdbint.c: scm_lread now has one more argument.
7344 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7345 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7346 loading source from non-file ports, which, e. g., happens when
7347 using the Emacs interface).
7349 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7352 * read.c: Added code for recording of positions of source code
7353 expressions; New functions: recsexpr, scm_lreadrecparen;
7354 _scm_make_srcprops --> scm_make_srcprops
7355 (scm_flush_ws): Removed updating of positions counters. This work
7356 is already done by scm_gen_getc
7358 * read.h: Added prototype for scm_lreadrecparen
7360 * print.c: Added #include "alist.h"
7362 * eval.c: Added #include "hash.h"
7364 * eq.c: Added #include "ramap.h"
7366 * options.c: Documentation fixes.
7368 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7369 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7370 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7371 --> scm_make_srcprops
7373 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7374 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7375 function calls in the definition of the whash access macros.
7377 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7379 * init.c (scm_boot_guile): Add level of indirection to
7380 scm_boot_guile_1() to ensure that stack base pointer is properly
7381 initialized. There was no guarantee that variable i was the
7382 highest/lowest variable on stack (i.e. the call frame of
7383 scm_boot_guile was not completely protected from gc).
7385 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7387 * ports.h (scm_port_table): put back file_name, it will be used to
7388 support debugging. Undo related changes in fports.c, ioext.c,
7391 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7393 * ports.h (scm_port_table): remove file_name member for now, it seems
7395 * fports.c (scm_open_file): don't set file_name in PTAB.
7396 (prinfport): don't use file_name in PTAB.
7397 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7398 * ports.c (scm_add_to_port_table): don't intialize file_name.
7399 (scm_port_file_name): remove for now.
7400 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7402 * fports.h (scm_mkfile): prototype deleted.
7403 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7405 * debug.c, unif.c: use scm_out_of_range instead of
7406 wta for range errors (ASSERT still needs work).
7408 * error.c, error.h (scm_out_of_range): new procedure.
7410 * error.c, error.h (scm_out_of_range_key): new key.
7412 * posix.c (scm_sync): #else was missing.
7414 * error.c, error.h: append _key to names scm_num_overflow and
7417 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7418 of consing an empty list.
7419 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7420 of macros, saves code and string space.
7421 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7422 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7423 lower case. Rename scm_syserror_m to scm_syserror_msg.
7424 error.h: prototypes for new procedures.
7426 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7428 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7430 * error.c, error.h: setup scm_num_overflow key.
7432 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7433 Remove definition of SCM_OVSCM_FLOW.
7435 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7437 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7438 explicit message and args.
7440 * error.c, error.h, __scm.h: change system_error_sym to
7443 * error.c (system_error_sym): remove leading %% from the Scheme name
7446 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7448 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7450 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7451 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7452 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7453 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7454 renamed. (These were introduced by unsupervised name
7457 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7459 * print.c: Added code for detection of circular references during
7460 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7461 a hook for printing of closures (accessible via print options).
7462 This leads to a split of calls to scm_iprin1 into two classes:
7463 elementary print operations (e. g. the code which prints a smob)
7464 still use scm_iprin1 while top level calls (like scm_display) use
7465 scm_prin1. scm_prin1 begins by clearing the data structure used
7466 to record reference information.
7468 * print.h: Added declarations of scm_prin1 and scm_prlist.
7470 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7472 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7474 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7476 * error.c (err_head): scm_iprin1 --> scm_prin1
7478 * debug.c: Adjusted header comment.
7482 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7484 * strerror.c: Doc fix.
7486 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7488 * gdbint.c (gdb_read): Now possible to run during GC.
7489 (unmark_port, remark_port): New functions.
7491 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7493 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7494 of allocating a new string object. Also, increase size by
7495 the factor 2 instead of 1.5.
7497 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7499 * __scm.h (SCM_P): Corrected to run under traditional C.
7501 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7504 * async.c: Calls to scm_sysintern corrected.
7506 * async.h (scm_async_clock): Redundant declaration removed.
7508 * continuations.c (scm_dynthrow): Redundant declaration removed.
7510 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7511 Definition typos corrected.
7513 * debug.h: Missing declarations of functions in debug.c added
7516 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7517 Missing declarations to functions in eval.c added.
7519 * filesys.c: Possibly uninitialized variable rv.
7521 * gc.h (scm_object_addr, scm_unhash_name): Missing
7522 declarations of functions defined in gc.c added.
7524 * genio.c: Possible typos str_data -> wstr_data. ???
7526 * genio.c: Possibly unintended shadowing of local variable
7527 `int c' (gotos out of scope of inner `c'). ???
7529 * init.c: Uninitialized `SCM last' may be used.
7531 * ioext.h: (scm_sys_isatty_p): Typo.
7533 * list.h (scm_list_head): Missing prototype for function in
7536 * numbers.c (scm_two_doubles): Changed from extern to static
7537 (is used only within numbers.c).
7539 * numbers.h: Repeated declarations removed.
7541 * ports.h (scm_close_all_ports_except): Declaration for the
7542 function defined in ports.c added.
7544 * posix.h: Missing declarations added.
7546 * procs.h (scm_make_subr_opt): Missing declaration added.
7548 * socket.h (scm_sys_gethost): Missing declaration added.
7550 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7552 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7553 Missing declarations added.
7555 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7557 * struct.c: Uninitialized variable `SCM answer' may be used.
7559 * unif.c (l2ra): Declaration prototype.
7561 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7562 defined in ramap.c).
7564 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7565 Redundant declarations removed (they are in ramap.h).
7567 * variable.h (scm_make_udvariable,
7568 scm_make_undefined_variable): Declaration corrected to
7569 correspond variable.c.
7571 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7572 Missing declarations added.
7574 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7576 * Makefile.in (distclean): Don't forget to delete fd.h.
7578 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7580 * fd.h.in, tags.h: Trivial cleanups.
7582 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7583 marksweep.h just declared functions from gc.c.
7584 * gc.h, libguile.h: Don't #include "marksweep.h".
7585 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7586 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7587 dependencies updated.
7589 * libguile.h: Don't #include "files.h"; it's been deleted.
7591 * files.c (scm_sys_delete_file): Moved to filesys.c.
7592 File is now empty; deleted.
7594 * filesys.c: scm_sys_delete_file is now here. Remove
7595 #if's; they seem to rely on remnants of an old portability
7596 regimen. If the problems come up again, solve them properly,
7597 using autoconf. Specifically: Don't test M_SYSV, and #define
7598 remove to be unlink if it's #defined; don't use remove just
7599 because HAVE_STDC_HEADERS is #defined.
7600 * filesys.h: Add declarations for scm_sys_delete_file.
7601 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7602 files.o, files.h, files.c, and files.x.
7603 * init.c: Don't #include "files.h", and don't call scm_init_files.
7605 Use SCM_P instead of PROTO; the latter intrudes on the user's
7607 * params.h: Deleted; definition of SCM_P moved to...
7608 * __scm.h: ... here, where it replaces PROTO macro.
7609 * libguile.h, smob.h: Don't #include "params.h".
7610 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7611 smob.h: Fix prototypes accordingly.
7612 * Makefile.in: Update dependencies.
7613 (inner_h_files): Remove params.h.
7615 * gc.c: #include "gc.h"; every module should include its header,
7616 to let the compiler cross-check the declarations against the
7619 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7620 simpos.h: #include "libguile/__scm.h".
7622 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7624 * init.c: Don't forget to #include smob.h and init.h.
7625 * Makefile.in: Dependencies updated.
7627 * smob.h: Use PROTO instead of #if __STDC__.
7629 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7631 * __scm.h: Doc fixes.
7633 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7634 <angles>; this allows `make depends' to work properly.
7636 * libguile.h: #include smob.h and pairs.h before the others; they
7637 define typedefs used by other headers.
7639 C files should #include only the header files they need, not
7640 libguile.h (which #includes all the header files); the pointless
7641 recompilation was wasting my time.
7642 * Makefile.in (all .o dependency lists): Regenerated.
7643 * libguile.h: Don't try to get a definition for size_t here...
7644 * __scm.h: Do it here.
7645 * _scm.h: Since this is the internal libguile header, put things
7646 here that all (or a majority) of the libguile files will want.
7647 Don't #include <libguile.h> here; that generates dependencies on
7648 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7649 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
7650 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

7747 * weaks.c: Get "weaks.h".
7749 * stackchk.h: #include "libguile/debug.h",
7751 * print.h, read.h: #include "options.h", since everyone who uses
7752 either of these files will need that.
7754 * smob.h: #include "ports.h", "genio.h", and "print.h", since
7755 anyone who uses this file will need them to define the smob
7756 printing functions. Also, get markers.h, since people will need
7757 to #define the mark functions.
7759 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
7760 * ports.h: ... to here.
7762 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7763 don't rely on archaic C default type rules.
7765 * fports.h: #include "libguile/ports.h", since you need that in
7766 order to parse this.
7768 * genio.h: #include "libguile/print.h", because you need that to
7769 parse this; don't bother #including "ports.h", since print.h gets
7772 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7774 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7775 this; it's now a reference to an element of *scm_root.
7777 * debug.h: Don't #include "options.h"; the compiler won't be able
7778 to find that once the headers are installed; instead, #include
7779 "libguile/options.h".
7780 * gc.h: Same, with marksweep.h.
7781 * mbstrings.h: Same, with symbols.h.
7782 * scmhob.h: Same, with _scm.h.
7783 * smob.h: Same, with params.h.
7785 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
7786 C files; there's no need for this, and it forces recompilations
7789 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
7791 * error.c (scm_error): declare scm_error_callback.
7793 * error.h: prototype for scm_error_callback.
7795 * __scm.h: define lgh_error.
7796 (SCM_SYSERROR): redefine using lgh_error.
7798 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
7800 * error.c (scm_error): new procedure.
7802 * error.h: prototype for scm_error.
7804 * Makefile.in (install): install scmconfig.h from the current
7805 directory, not $(srcdir).
7807 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7809 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7810 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7811 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
7812 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
7813 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
7814 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
7815 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
7816 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
7817 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7818 vports.h, weaks.h: #include "libguile/__scm.h", not
7819 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
7820 dependencies are within libguile properly.
7822 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7824 * Makefile.in (.c.x): Simplify; there's no need to run this rule
7825 when scmconfig.h doesn't exist.
7827 * load.c (scm_sys_try_load): Correct spelling.
7829 * feature.c (scm_loc_features): Make this static.
7831 * Makefile.in (libpath.h): Omit trailing slash from path. We
7832 shouldn't require it of users, so why put it here?
7834 Move code to initialize and search %load-path from ice-9 to C
7835 code, so we can use the load-path to find the ice-9 boot code;
7836 this makes it easier to run Guile without installing it. See
7837 corresponding changes in guile/Makefile.in.
7838 * feature.c: Move stuff concerned with the load path to load.c.
7839 (scm_compiled_library_path): Deleted.
7840 Don't #include libpath.h here.
7841 * feature.h: Don't mention scm_compiled_library_path.
7842 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
7843 <sys/stat.h>, and <unistd.h> (if present).
7844 (R_OK): #define if the system hasn't deigned to.
7845 (scm_loc_load_path): New variable.
7846 (scm_init_load_path, scm_sys_search_load_path,
7847 scm_sys_try_load_path): New functions.
7848 (scm_init_load): Initialize scm_loc_load_path to point to the
7849 value cell of the Scheme %load-path variable.
7850 * load.h: Add declarations for scm_sys_search_load_path,
7851 scm_sys_try_load_path.
7852 * init.c: Call scm_init_load_path.
7853 * Makefile.in (feature.o, load.o): Dependencies updated.
7855 * load.c, load.h: Rewrite using PROTO macro.
7857 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7859 * gc.c (scm_cellp): New function: C predicate to determine if an
7860 SCM value can be regarded as a pointer to a cell on the heap.
7862 * gc.h: Added declaration of scm_cellp.
7864 * gdb_interface.h: New file: The GDB interface header from the GDB
7867 * gdbint.c: New file: GDB interface.
7869 * gdbint.h: New file: GDB interface.
7871 * libguile.h: Added #include <libguile/gdbint.h>.
7873 * init.c (scm_boot_guile): Added scm_init_gdbint.
7875 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
7876 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
7877 found if object files and source are kept separate).
7879 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
7881 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
7883 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
7885 * configure.in: Don't substitute the values of TCL_SRC_DIR and
7886 TK_SRC_DIR; they're not relevant any more.
7888 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
7889 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
7891 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
7893 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
7894 search path, so we can find the <libguile/MUMBLE.h> headers.
7896 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
7898 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
7899 implicit in the .c.o rule.
7900 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
7903 Put the library path in a header file, instead of passing it on
7904 the command line in every compilation.
7905 * Makefile.in (libpath.h): New target.
7906 (feature.o): Depend on libpath.h.
7907 (clean): Delete libpath.h.
7908 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
7909 * feature.c: ... #include "libpath.h" here.
7910 * .cvsignore: Ignore libpath.h.
7912 Don't install the unwashed masses of Guile header files in the
7913 main #include path; put most of them in a subdirectory called
7914 'libguile'. This avoids naming conflicts between Guile header
7915 files and system header files (of which there were a few).
7916 * Makefile.in (pkgincludedir): Deleted.
7917 (innerincludedir): New variable; this and $(includedir) are enough.
7918 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
7919 (installed_h_files): Divide this up. Now this variable lists
7920 those header files which should go into $(includedir) (i.e. appear
7921 directly in the #include path), and ...
7922 (inner_h_files): ... this new variable says which files appear in
7923 a subdirectory, and are referred to as <libguile/mumble.h>.
7924 (h_files): List them both.
7925 (install): Create innerincludedir, not pkgincludedir. Put
7926 the installed_h_files and inner_h_files in their proper places.
7927 (uninstall): Corresponding changes.
7928 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7929 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7930 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
7931 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
7932 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
7933 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
7934 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
7935 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
7936 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7937 vports.h, weaks.h: Find __scm.h in its new location.
7938 * __scm.h: Find scmconfig.h and tags.h in their new locations
7939 (they're both "inner" files).
7941 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
7943 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
7945 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7947 * posix.c: Doc fixes.
7949 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
7951 * socket.c: Don't include a prototype for inet_aton; just use a
7952 K&R style declaration, to avoid warnings but minimize the chance
7953 of conflicts with the system.
7955 On NextStep, <utime.h> doesn't define struct utime, unless we
7956 #define _POSIX_SOURCE before #including it.
7957 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
7958 * acconfig.h: New comment text for above CPP symbol.
7959 * configure.in: Call it.
7960 * posix.c: #define _POSIX_SOURCE if it seems necessary.
7962 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
7964 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
7965 testing for __EMX__.
7967 * posix.c: #include <libc.h>, if it exists.
7969 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
7970 don't even know if the latter exists.
7972 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
7973 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
7974 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
7976 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
7978 (scm_init_posix): Use them when initializing the Scheme constants
7981 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7983 * Makefile.in (libdir, includedir, bindir): Use the
7984 autoconf-supplied values, instead of deriving them ourselves.
7985 (pkgincludedir, datadir, pkgdatadir): New variables.
7986 (install, uninstall): Put the header files in a special
7987 subdirectory, not in the main search path.
7989 * Makefile.in (ALL_CFLAGS): Provide the proper value for
7990 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
7992 * Makefile.in (IMPLPATH): Deleted; never used.
7994 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
7995 on the Tcl/Tk source any more.
7996 (INCLUDE_CFLAGS): Remove references to the above.
7998 * Makefile.in (version.o): Corrected dependencies.
8000 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
8002 * libguile.h: #include "version.h"
8004 * init.c (scm_boot_guile): Call scm_init_version.
8005 * gscm.c (gscm_run_scm): Call scm_init_version.
8007 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
8008 GUILE_VERSION): AC_DEFINE these.
8009 (acconfig.h): #undef the above symbols.
8011 * Makefile.in (libobjs): Add version.o.
8012 (installed_h_files): Add version.h.
8013 (c_files): Add version.c.
8014 (gen_c_files): Add version.x.
8015 (version.o): New rule.
8016 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
8017 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
8018 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
8019 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
8020 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
8021 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
8022 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
8023 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
8024 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
8025 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
8026 weaks.o): Add version.h to dependency lists.
8027 (markers.o): Remove duplicate rule.
8029 * version.h: New file.
8031 * version.c: New file.
8033 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8035 * symbols.c (scm_strhash): scm_downcase is now a function, not an
8036 array; use it appropriately. Since GCC is quite happy to
8037 subscript functions, it never warned us about this; we should use
8038 -Wpointer-arith in the future. I guess we never tested
8041 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
8043 * socket.c: Doc and copyright fixes.
8045 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8047 * debug.c: Fixed and improved gdb support.
8049 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8051 * socket.c: Added declaration of inet_aton to avoid compiler
8052 warning. (Hope this solution is correct.)
8054 * stime.c: Added declaration of ftime. (This is missing in
8057 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
8059 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8061 * Makefile.in (c_files): add strerror.c.
8063 * strerror.c: new file from Emacs' sysdep.c.
8064 maybe configure should also check for sys_errlist.
8066 * configure.in (AC_REPLACE_FUNCS): add strerror.
8068 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8070 * debug.c (scm_init_debug): Added initialization for
8071 scm_evaluator_traps.
8073 * debug.h, debug.c: Various name changes.
8074 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
8075 "debug-options-interface". See commentary in options.c.
8077 * options.h, options.c: Options now have documentation strings.
8078 Also added a long explanatory commentary.
8080 * eval.c, print.h, print.c, read.h, read.c: Modifications to
8083 * gscm.c, init.c, root.c, throw.c: Bug fixes:
8084 last_debug_info_frame is now updated in all cases.
8086 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
8089 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
8091 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
8092 Added option STACK_CHECKING.
8094 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
8096 * Makefile.in: Added {debug,options,srcprop}.{h,c}
8098 * __scm.h: Removed symbols for debugging support.
8100 * acconfig.h: Added symbols for debugging support.
8102 * configure.in: Added user option for debugging support.
8103 --enable-debug will include the debugging code into libguile.a.
8105 * continuations.c (scm_make_cont): Enlarged the #if 0 around
8106 scm_relocate_chunk_to_heap.
8108 * debug.c: New file: low-level debugging support. It also
8109 includes support for debugging with gdb. (The extensions to gdb
8110 are written by Per Bothner at Cygnus.)
8112 * debug.h: New file: low-level debugging support.
8114 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
8115 argument pairs. Extensive modifications to the debugging
8116 evaluator. Added "SECTION:" commentaries to clarify what happens
8117 when, during double compilation. Renamed EVALIMP --> EVALIM.
8118 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
8119 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
8120 the beginning of the file. New procedure: scm_unmemocopy.
8121 Added some global state variables needed by the debugging
8122 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
8123 check_entry, check_apply, check_exit, debug_options and
8124 evaluator_traps. New acro: undefine.
8126 * eval.h: Renamed EVAL --> XEVAL.
8128 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
8129 --> scm_make_weak_key_hash_table.
8131 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
8132 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
8134 * libguile.h: Conditionally include debug.h
8136 * objprop.c (scm_object_properties, scm_set_object_properties_x):
8137 scm_object_properties shouldn't return handle. `handle' now gets
8138 initialized in scm_set_object_properties_x. scm_object_properties
8139 doesn't any longer create an entry in scm_object_whash.
8141 * options.c: New file: handling of run time options.
8143 * options.h: New file: handling of run time options.
8145 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
8147 * print.c: New procedure: scm_print_options
8149 * print.h: Defines for print options.
8151 * read.c: New procedure: scm_read_options
8153 * read.h: Defines for reader options.
8155 * root.h: Added scm_source_whash among scm_sys_protects.
8157 * srcprop.c: New file: source properties.
8159 * srcprop.h: New file: source properties.
8161 * throw.c (jbsmob): Jump buffers are now correctly allocated.
8162 (Bug found by A. Green.)
8164 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8166 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8168 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
8170 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8172 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8173 and should be called by the final client.
8175 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8177 * gc.h: Use the PROTO macro when declaring functions.
8178 * gc.c: Use the PROTO macro when declaring static functions.
8179 Remove the CPP hair around function definitions.
8181 * gc.c (scm_init_storage): Initialize scm_asyncs.
8183 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8184 preprocessor symbol; "__scm.h" is where it might get #defined.
8185 * __scm.h: Similar: #include <scmconfig.h> before testing
8188 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8190 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8192 * init.c (scm_boot_guile): Add init_func argument; call
8193 (*init_func) instead of calling scm_appinit; it's ucky to
8194 hard-code names for the user's procedures.
8195 * init.h (scm_boot_guile): Adjust declaration.
8197 * __scm.h (PROTO): New macro, for declaring functions with
8200 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8201 eliminate all the __STDC__ conditionals.
8202 (scm_boot_guile): Add declaration.
8203 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8204 Remove __STDC__ conditionals around function definitions; the
8205 declarations in init.h will provide the same information, more
8208 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8209 complain about it in the error message; the error message is
8210 adequate without that note, and there's nothing the user can do
8213 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8215 * Makefile.in (ancillary): Drop def.sed.
8217 * posix.c (scm_init_posix): Use numeric values, rather than
8218 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8219 F_OK. The symbols aren't available on some systems, and I'm
8220 pretty sure their values are fixed by common widespread practice.
8221 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8223 More functions unavailable on some systems.
8224 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8225 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8227 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8228 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8229 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8230 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8231 stub that signals an error as the #else.
8233 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8235 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8237 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8239 * unif.c: include ramap.h.
8241 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8243 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8245 * ports.c: include sys/ioctl.h.
8247 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8249 * configure.in: check for sys/ioctl.h.
8251 * ports.c: include <malloc.h> not "malloc.h".
8253 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8255 * fports.c: remove ttyname and tmpnam declarations.
8257 * posix.c: fewer ttyname declarations.
8259 * fports.c: include <string.h> not "string.h".
8261 * init.c, ioext.c: include string.h and unistd.h.

8285 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8287 Changes for NeXT, suggested by Robert Brown.
8288 * configure.in: Call AC_TYPE_MODE_T.
8289 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8290 NeXT. Put header file list in alphabetical order.
8291 * configure, scmconfig.h.in: Regenerated.
8292 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8294 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8297 * acconfig.h: New file, providing documentation for the CPP
8298 symbols defined in configure.in
8299 * acconfig-1.5.h: Removed; superceded by the above.
8301 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>

8307 * ioext.c (fileno): renamed from %fileno.
8308 (soft-fileno): deleted.
8310 * ports.c (scm_port_revealed): don't need to check for -1 from
8312 (scm_set_port_revealed_x): return unspecified, not #f.

8322 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8324 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8325 This is necessary on Ultrix, and doesn't hurt portability.
8327 * Makefile.in (dist-dir): New target, implementing a new dist system.
8328 (installed_h_files): Put in alphabetical order.
8329 Remove duplicate entries for markers.h and unif.h.

8331 (ancillary): Renamed from anillery; all uses changed. Remove
8332 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8333 Remove all the ../doc/* files; doc/Makefile.in handles that.
8335 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8337 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8338 every if must have an else, or else the whole command has a
8339 non-zero exit code whenever the if's condition is false.
8341 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>

8405 * ports.c (scm_ports_prehistory): size malloced here doesn't
8406 matter so long as it is non-0 (got rid of "* 4").
8408 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8410 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8411 since its definition was bogus).
8413 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8415 * mallocs.[ch]: back again (for rx at least).
8417 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8419 * ports.c: removed functions relating to the mapping between ports
8420 and descriptors. (That stuff is unix-specific and should be collected
8421 in a separate library).

8428 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8429 handled correctly (SCM_FREEP was applied to them) -- test for
8430 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

8485 * ports.c (scm_add_to_port_table): Added fields
8486 to port table entries: file_name, line_num, col.

8488 Added procedures to access those fields.
8490 Sun Feb 25 00:10:36 1996 Tom Lord <lord@beehive>

8598 initialization to fix a race condition.
8600 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

8624 set the multi_byte flag correctly in symbols. This is wrong.
8625 intern_obbary_soft and msymbolize should take an extra parameter.
8626 Also, weird multibyte symbols don't print correctly.
8627 The weird symbol syntax is also a bit bogus (emacs doesn't quite
