1 1999-08-20 James Blandy <jimb@mule.m17n.org>
3 * ports.h (enum scm_port_rw_active): New enum, containing
4 SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of
5 zero). The debugger knows about enums, but doesn't know about
7 (typedef scm_port): Declare rw_active member to be an enum
9 * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER
11 * ports.c (scm_add_to_port_table): Same.
12 * strports.c (st_flush, st_end_input): Same.
14 * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc,
15 scm_must_realloc, and scm_done_malloc as appropriate.
17 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
19 * sort.c (quicksort): Added condition to protect the algorithm
20 from crashing the interpreter if the less predicate is buggy.
22 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
24 * fports.c (fport_write): fix line-buffering mode again.
25 (scm_open_file): recognise 'l' for line-buffering.
26 (scm_setvbuf): recognise _IOLBF for line-buffering.
28 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
30 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
33 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
36 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
38 * fports.c (fport_write): use memcpy instead of strncpy, in case
39 the data contains NUL.
41 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
43 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
45 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
46 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
47 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
48 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
49 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
50 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
51 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
52 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
53 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
54 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
55 scm_sym_ as prefix for symbols.
57 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
59 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
60 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
61 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
62 scm_sym_atcall_cc): Made global.
64 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
66 * eval.c (scm_sym_args): Made global.
68 * objects.c (scm_set_object_procedure_x): Disallow setting of
69 procedures for pure generic functions.
71 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
73 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
74 Scheme name from lseek to seek, but lseek was added recently so
75 it shouldn't be a big problem.
76 * ports.c, gdbint.c, ioext.c: changed callers.
78 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
80 * fports.c (fport_input_waiting): if select is used, return 1
81 instead of whatever FD_ISSET expands to. maybe it will be useful
82 to interpret the value from the input_waiting ptob procedure as a
83 lower bound on the number of bytes available.
85 * Mikael asked for a few names to be changed...
87 * ports.c (scm_make_port_type): take the write procedure as the
88 second argument instead of the flush procedure.
89 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
90 fflush -> flush, read_flush -> end_input, fclose -> close,
91 fill_buffer -> fill_input, ftruncate -> truncate,
92 input_waiting_p -> input_waiting.
94 * ports.c (end_input_void_port): was read_flush_void_port.
95 (scm_set_port_end_input): was scm_set_port_flush_input.
96 (scm_set_port_flush): was scm_set_port_write.
97 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
98 (scm_end_input): was scm_read_flush.
99 (scm_fill_input): was scm_fill_buffer.
100 (scm_flush): was scm_fflush.
101 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
102 (fport_end_input): was local_read_flush.
103 (fport_flush): was local_fflush.
104 (fport_close): was local_fclose.
105 (fport_truncate): was local_ftruncate.
106 (fport_seek): was local_seek.
107 (fport_free): was local_free.
108 (fport_fill_input): was fport_fill_buffer.
109 * strports.c (st_end_input): was st_read_flush.
110 (st_truncate): was st_ftruncate.
111 * vports.c: (sf_flush): was sfflush.
112 (sf_close): was sfclose.
113 (sf_fill_input): was sf_fill_buffer.
115 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
118 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
120 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
121 forms now contain the expressions to be dispatched upon instead of
122 depending on a surrounding lambda or let; Generic function
123 dispatch has been optimized; `apply' on a generic function now
124 works a little bit strangely. It uses a trick so that the type
125 dispatch code in SCM_CEVAL can be reused.
127 * objects.h, objects.c (scm_apply_generic_env): Added (used by
129 (scm_operator_p): Added.
130 (scm_sym_atdispatch): Added.
131 (scm_set_object_procedure_x): Modified to handle the new style
133 (scm_object_procedures): New debugging procedure.
135 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
137 * eval.c, eval.h (scm_sym_args): Added.
139 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
141 * feature.c, feature.h (scm_c_run_hook): Added.
143 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
144 cdrxnoap and loopnoap instead of begin and loop.
146 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
148 * ports.c (scm_putc, scm_puts),
149 * unif.c (scm_uniform_array_write): use scm_lfwrite.
150 * ports.c (scm_putc): change type of first argument from int to char.
152 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
154 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
155 SCM_IM_HASH_DISPATCH.
157 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
158 (scm_si_redfined, scm_si_hashsets): Moved.
160 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
161 flag which combines type and status info so that the class
162 redefinition protocol has zero cost during normal execution.
164 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
166 * ports.h (scm_ptob_descriptor): include a write procedure again.
167 it's more efficient for unbuffered fports (e.g., sockets.)
169 * ports.c (scm_puts): use ptob->write.
170 * vports.c (scm_make_sfptob): set write proc in ptob.
171 * strports.c (scm_make_stptob): set write proc in ptob.
172 * ports.c (write_void_port): new procedure.
173 * vports.c (sf_write): new procedure.
174 * ports.c (scm_lfwrite): use ptob->write.
175 * strports.c (st_write): new procedure.
176 * fports.c (fport_write): new procedure.
177 (scm_make_fptob): set write in ptob to fport_write.
178 * ports.h: prototype for scm_set_port_write.
179 * ports.c (scm_make_port_type): initialise ptob write procedure.
180 (scm_set_port_write): new proc.
182 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
184 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
185 until we've verified that it is actually a port. (Thanks to
188 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
190 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
191 code, particularly an unnecessary test (len != size, where len ==
192 size). (Was this leftovers from debugging code, or have I missed
195 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
196 size. (Thanks to James Dean Palmer.)
198 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
199 (Thanks to Lorentey Karoly.)
201 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
203 * eval.c (scm_m_expand_body): Use scm_cons_source.
205 * struct.c (scm_print_struct): Use vtable name.
207 * print.c (scm_init_print): Set name of print state type.
209 * stacks.c (scm_init_stacks): Set name of stack type.
211 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
213 * eval.c (SCM_CEVAL): Removed old implementation of internal
216 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
218 * debug.c, debug.h (scm_reverse_lookup): Added.
219 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
220 internal procedure definitions; Don't use scm_i_inner_name.
222 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
225 * eval.h: Added prototypes for multi language support functions.
227 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
228 improper lists in the low-level representation, since that will
229 cause a begin to be prepended at macro expansion.
231 * eval.c (scm_cons_source): Version of cons which copies source
232 properties from an existing cell.
233 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
235 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
236 procedure source before calling scm_unmemocopy instead of faking
239 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
241 Ported `internal defines' fix from SCM. Original ChangeLog entry:
243 1998-07-09 Radey Shouman <radey@colorage.com>
245 * eval.c (ceval_1): Modifications to allow rewriting of interal
246 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
247 body of which it is the CAR is macro expanded by m_expand_body,
248 which rewrites internal DEFINE.
250 (m_expand_body): Added.
252 (m_macroexp1): Added argument to control error checking:
253 m_expand_body may speculatively expand forms in the wrong
254 environments. Made argument number checks conditional on
257 (m_body): Added, error checks bodies and inserts the ISYM tokens.
259 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
262 (m_cond): (m_case): (m_quote): Modified to avoid destructively
263 changing their argument forms. Since m_expand_body
264 speculatively macro expands forms the process must be
267 (m_ident_eqp): Fixed to use proper environment.
269 (renamed_ident): Added DEFER_INTS_EGC.
271 Added prototypes for static functions.
277 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
278 is false, do not produce an error for unbound variables, return a
279 pointer to cell_undef instead.
281 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
285 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
286 destructively changing their argument forms. Since m_expand_body
287 speculatively macro expands forms the process must be reversible.
289 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
290 SCM_IM_LET introduced by named lets.
292 (scm_m_letstar): Use scm_m_body instead of bodycheck.
294 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
295 scm_letrec. scm_letrec1 does not check for a null binding and
296 takes an additional argument to specify the ISYM of the body. Use
297 scm_m_body instead of bodycheck.
299 (scm_m_let): Use scm_m_body instead of bodycheck.
301 (scm_m_expand_body, scm_macroexp): New.
303 (unmemocopy): Account for ISYMs introduced by scm_m_body.
305 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
306 check=1. Throw error for internal defined that have not been
307 rewritten by scm_m_expand_body.
309 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
310 Removed prototype for SCM_APPLY.
312 * tags.h: Added extern declaration of scm_isymnames.
314 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
316 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
318 * lang.c: New file: Beginning of multi-language support.
320 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
322 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
323 (scm_dynamic_wind): Added argument checking for the after guard so
324 that we don't add garbage on the dynwind chain.
325 (scm_swap_bindings): Added.
327 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
328 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
329 (scm_isymnames): New isyms for multi-language support.
331 * eval.c (scm_nil, scm_t): New symbols.
332 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
333 forms for multi-language support.
335 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
337 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
339 Renamed functions in the random function library interface
340 from scm_i_XXX --> scm_c_XXX.
342 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
344 * ports.c (scm_putc): fix line-buffering.
346 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
348 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
349 scm_set_ptob_XXX --> scm_set_port_XXX.
351 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
353 * ports.c, ports.h (scm_make_port_type): New interface for
354 creation of port types (replaces scm_newptob). Just as for the
355 smobs, we need to separate the internal representation of smob
356 types from the interface, so that we easily can add new fields and
357 rearrange things without caring about backward compatibility.
358 This change was forced by the need in GOOPS to create classes
359 representing port types.
360 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
361 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
362 scm_set_ptob_seek, scm_set_ptob_truncate,
363 scm_set_ptob_input_waiting_p): New setters.
364 (scm_newptob): Rewritten to use scm_make_port_type. For backward
366 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
367 (scm_prinport): Removed.
368 (scm_port_print): Added.
369 (scm_print_port_mode): Added.
370 (void_port_ptob, print_void_port, close_void_port, noop0):
371 Removed. Removed #include "genio.h" Added #include "objects.h",
374 * fports.c (prinfport): Moved code from ports.c.
376 (scm_fptob): Removed. Instead use new interface.
377 (scm_make_fptob): Added. (Need to create basic ports in a
378 specific order in ports.c.)
380 * strports.c (scm_stptob, prinstpt, noop0): Removed
381 (scm_make_stptob): Added.
383 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
384 (scm_make_sfport): Added.
386 * filesys.c (scm_dir_print): Don't use the port printing code.
387 Instead provide specific directory printer.
389 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
391 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
394 * smob.c (scm_smob_print): Handle non-existing type name nicely.
395 Removed #include "genio.h"
397 * objects.c (scm_make_port_classes): New function ptr.
399 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
401 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
403 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
404 allow the 1st argument to be a fdes or filename as well as a
405 port (as in the filesys.c version).
407 * filesys.c (scm_truncate_file): removed.
409 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
411 * readline.c, readline.h: Removed.
413 * objects.c, objects.h (scm_port_class): Added.
414 (scm_class_of): Look up port class in scm_port_class.
415 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
416 SCM_INOUT_PCLASS_INDEX): Added.
419 * Makefile.am: Removed genio.c, genio.x.
423 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
425 * init.c: Make sure that scm_post_boot_init_modules is called only
426 once. (Important when using a dumped image.; Thanks to Bernard
429 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
431 * guardians.c (scm_guardian_zombify): Separate scanning for
432 zombies from marking the pairs of the free list.
434 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
435 use the macros. (Thanks to Michael Livshin.)
437 * eval.c (scm_m_lambda): Let bodycheck check the body of the
438 lambda. Let your sins be purified by the blood of the lambda.
439 (Thanks to Eric Hanchrow.)
441 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
442 (Thanks to Valdis Kletnieks.)
444 Fixes for EMX from Mikael Ståldal.
446 * filesys.c: #include <io.h>, if we have it.
447 * scmconfig.h.in: Regenerated.
449 * stime.c (ftime): Delete declaration for this function --- let
450 the system supply it.
452 Cleanups from John Bley.
454 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
456 * gsubr.c: Don't include "gsubr.h" twice.
458 Cleanups for compilation on Irix 6, from David Kaelbling.
460 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
461 regex_t pointer. This is what the callers have, mostly.
462 (scm_regexp_exec): Don't forget to pass the `rx' argument to
463 scm_regexp_error_msg.
465 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
466 int. That way, if we get a warning on this line, it's more likely
467 that we're really missing bits we care about.
469 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
472 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
473 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
474 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
475 cast at all is more appropriate in every case. At the moment, we
476 assume everywhere that SCM is an integral type anyway.
478 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
480 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
481 read_pos after scm_fill_buffer.
483 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
486 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
487 fports.c (fport_fill_buffer): implement the interface change.
489 * ports.c (scm_fill_buffer): interface change: no longer increments
490 read_pos past the character that's returned. it seems clearer to
491 leave it to the caller to decide what to do (thanks Jim).
493 * vports.c (sf_fill_buffer): put the read char into the buffer
494 as well as returning it.
496 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure
499 1999-07-13 Gary Houston <ghouston@easynet.co.uk>
501 * strports.c (scm_strprint_obj): simplify. start with initial
503 (st_seek): don't allow string to be extended if seeking past
504 the end of a read-only port.
506 1999-07-12 Gary Houston <ghouston@easynet.co.uk>
508 * strports.c (st_seek): change the resize checks.
510 * ports.c (scm_ftruncate): throw error if offset works out negative.
512 * strports.c (st_flush): increase string size in blocks of
513 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
514 it's greater and reset read_buf_size.
515 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
516 to be maintained for output ports too (it holds the written
517 part of the string, while write_buf may have unwritten buffer
519 (st_truncate): rewritten.
520 (top of file): added a few notes.
522 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
524 Patch from Greg Badros:
525 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
526 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
527 (function pointer) argument to scm_make_gsubr and scm_make_subr
528 calls. This avoids warnings in C++ programs using guile-snarf.
530 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
532 * strports.c (st_grow_port): set pt->read_pos. set
533 pt->read_buf_size one less than pt->write_buf_size if there's

786 instead of stepping through an array.
787 (scm_gc_sweep): Update offset used to find start of weak vector to
789 (scm_init_storage): Set scm_weak_vectors to EOL.
791 Fix from Ken Raeburn <raeburn@raeburn.org>:
792 * gc.c (already_in_gc): New variable.

798 Fix from Gary Houston:
799 * fports.c (local_seek): Signal an error if the seek fails.
800 * ports.c (scm_lseek): Don't check return value of port's seek

813 ChangeLog entries and the patch from two different places...
815 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
817 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
818 it shows up as terrible performance, as we GC constantly.
820 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
821 newline. A bit faster, and definitely hairier.
822 (scm_read_line): Count newlines here instead.
824 * strings.c (scm_take_str): New function.
825 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h

840 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
842 * ports.c: (scm_lseek): clear buffers even if just reading current
845 * fports.c (local_fclose): call local_fflush unconditionally.

863 fports.h (scm_port): change size types from int to off_t.
864 ports.c (scm_init_ports): initialise the seek symbols here
865 instead of in ioext.c.
866 strports.c (scm_call_with_output_string): start with an empty
867 string, so seek and ftruncate can be used.
869 gdbint.c: adjust string port usage.
871 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
873 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
874 equivalent to fflush for the read buffer.

876 ports.c (void_port_ptob): set read_flush.
877 fports.c (local_read_flush): new proc. add to ptob.

881 left but fdes. leaving it as a struct to allow for future changes.
882 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
883 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
884 ptob proc if the read buffer is filled.
886 1999-04-23 Gary Houston <ghouston@easynet.co.uk>

889 reading and writing members with rw_active member.
890 SCM_PORT_READ/SCM_PORT_WRITE: new values.
892 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
894 * ports.h (struct scm_port_table): add writing and reading members
895 to replace write_needs_seek: it isn't good enough for non-fports.
896 ports.c, ioext.c, fports.c: corresponding changes.
897 (struct scm_port_table): give it a typedef and rename to scm_port.
898 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
899 corresponding changes.

909 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
910 signals (it was only being done for handlers installed from Scheme).
911 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
912 waiting for input caused an EINTR error from read.
914 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
916 * ports.h (struct scm_port_table): make all the char members
917 unsigned, so they convert to int without becoming negative if large.
919 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
921 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
922 with threads enabled. rename this procedure to
923 fport_wait_for_input and take a port instead of a fdes.
924 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
926 * readline.c (scm_readline): Applied a patch from Greg Harvey to
927 get readline support working again: use fdopen to get FILE objects.
929 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
931 * gc.c (scm_init_storage): install an atexit proc to flush the
933 (cleanup): the new proc. it sets a global variable which can be
934 checked by the ptob flush procs to avoid trying to throw
935 exceptions during exit. not very pleasant but it seems more reliable.
936 * fports.c (local_fflush): check terminating variable and if set
937 don't throw exception.
938 * CHECKME: that the atexit proc is installed if unexec used.
940 * throw.c (scm_handle_by_message): don't flush all ports here.
941 it still causes bus errors.
943 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
946 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
948 * ports.c (scm_char_ready_p): check the port buffer and call the
949 ptob entry if needed.
951 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
952 ptob initialisers. use it in char-ready
954 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
956 * vports.c (sfflush): modified to write a char (since softports
957 currently use shortbuf.)
959 * fports.c (scm_standard_stream_to_port): moved to init.c and
962 * init.c (scm_init_standard_ports): make stdout and stderr
963 unbuffered if connected to a terminal. with stdio they
964 were line-buffered by default.
966 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
969 * ports.h (scm_ptobfuns): change fflush return to void.
970 change flush proc definitions.
972 * strports.c (scm_call_with_output_string): get size from
973 buffer instead of port stream.
974 (st_flush): new proc.
976 * ports.h (struct scm_port_table): added write_end member,
977 as an optimisation. set it where write_buf_size is set.
979 * ports.h (struct scm_port_table): change stream from void *
980 back to SCM. SCM presumably must be large enough to hold a
981 pointer (and probably vice versa but who knows.)
982 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
984 (scm_puts): rewritten
985 * fports.c (local_ffwrite, local_fputs): removed.
986 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)
987 * vports.c (sfputc, sfputs, sfwrite) likewise.

997 * ports.h (scm_ptobfuns): add seek function pointer.
998 * fports.c: set it to local_seek, new procedure.
1001 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
1002 use ptob for seek. take ptob instead of fport arg.
1004 * ports.h (struct scm_port_table): new member write_needs_seek,
1005 replaces reading member in fport struct.
1007 * vports.c (sfgetc): store the getted char into the buffer.
1008 rename to sf_fill_buffer and install it for fill-buffer in ptob.
1009 the Scheme interface is still a procedure that gets a char.
1010 (scm_make_soft_port): set up the port buffer (shortbuf).
1012 * fports.c (local_fgetc, local_fgets): deleted.
1013 * strports.c (stgetc): likewise.
1014 * ports.c: scm_generic_fgets: likewise.
1016 * ports.h (scm_ptobfuns): add fill_buffer.
1017 * ports.c (scm_newptob): assign it.
1018 * strports.c (scm_mkstrport): set up the buffer.
1019 put just the string into the stream, not cons (pos stream).
1020 (stfill_buffer): new proc.
1022 * ports.h: fport buffer moved into port table: to be
1023 used for all port types.
1025 1998-12-20 Gary Houston <ghouston@easynet.co.uk>
1027 * throw.c (scm_handle_by_message): flush ports at exit.

1032 scm_getpeername, scm_recv, scm_send, scm_recvfrom,
1034 use SCM_FPORT_FDES. use SCM_OPFPORTP not SCM_FPORTP.
1036 * posix.c (scm_getgroups): use SCM_ALLOW/DEFER_INTS.
1037 (scm_ttyname): use SCM_FPORT_FDES.
1038 (scm_tcgetpgrp, scm_tcsetpgrp): likewise.
1040 * filesys.c (scm_chown): use SCM_FPORT_FDES.
1041 (scm_chmod, scm_stat, scm_truncate_file: likewise.
1043 * ioext.c (scm_isatty_p): use SCM_FPORT_FDES.

1045 (scm_fdopen): use scm_fdes_to_port.
1047 * ports.c (scm_init_ports): don't try to flush ports using
1048 atexit(). it's too late, errors will cause SEGV.
1050 * fports.c (scm_fport_buffer_add): new procedure.
1052 * fports.h (SCM_FDES_RANDOM_P): new macro. use it in
1053 scm_fdes_to_port and scm_redirect_port.
1055 * ioext.c (scm_redirect_port): use setvbuf to set buffers in the

1218 * strop.c (scm_string_capitalize_x): Use the SCM object `s' in
1219 error messages, not the uninitialized string `str'. Love that
1222 * strop.c (scm_substring_move_x): New function, which can handle
1223 arbitrary overlapping substrings.
1224 (substring-move-left!, substring-move-right!): These are

1298 1999-03-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1300 * numbers.c (isfinite): Define this macro if not defined: Return a
1301 non-zero value if X is finite. (From ISO C 9x standard.)

1354 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1356 Most of this batch of changes is about how to deal with extended
1357 types when an object system is loaded into Guile. A nice object
1358 system is capable of representing Guile's types as class objects.
1360 For example, we want a regular expression to be of class <regex>.
1361 But regular expressions are smobs which aren't under direct
1362 control of the object system, so there has to be some mechanism
1363 which informs the object system that a new class should be created
1364 which can represent the smob type. I call this a "wrapper class".
1366 * objects.c: #include "smob.h";
1367 (scm_class_keyword): Removed. (Class is automatically created by
1369 (scm_smob_class): Array of smob classes indexed by smobnum.
1370 (scm_make_extended_class): "Plugin" function pointer for creation
1371 of wrapper classes for smob and struct types.
1372 (scm_class_of): Handle compiled closures. (Currently regarded as
1374 Use scm_smob_class to handle smob types;
1375 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1376 through scm_smob_class;
1379 * smob.c (scm_newsmob): Also create a wrapper class if
1380 scm_smob_class has been initialized.
1382 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1383 type code and smobnum.
1385 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1386 (scm_struct_table): Weak key table with auxilliary information for
1387 struct types. Currently used for names and wrapper classes.
1388 (scm_struct_ihashq): Hash function for structs.
1389 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1390 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1391 for accessing names of vtables. The record implementation in
1392 boot-9.scm currently uses the setter to record the name of record
1393 types. When the object system is initialized, it can use this
1394 information to create wrapper classes with suitable names.
1395 (scm_init_struct): Allocate scm_struct_table.
1396 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1397 (struct tags are a finite resource and we might want to restrict
1398 the use of tags to vtables only. E.g., Goops only uses tags for
1400 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1402 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1405 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1406 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1407 Used for access of struct table entries.
1409 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1410 (scm_hash_fold): New procedure. Used to process all entries in a
1411 hash table (in no particular order).
1413 Argh! For the umpteenth time I got compilation errors because of
1414 the "intuitive" name `kw'. This has to have an end:
1416 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1417 "kw" --> "keywords" everywhere.
1418 (I doubt that this will cause big compatibility problems since the
1419 application interface is unaffected.)
1421 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1423 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1425 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1426 column inums to native form.
1428 Improvement of backtraces: Introduces a new stack narrowing
1429 specifier, #t, for the inner cut. (See further in the comments in
1430 stacks.c:narrow_stack ().)

1433 (Used to flag certain system procedures which shouldn't turn up in
1436 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1437 modules which aren't "user" modules and the code of which
1438 shouldn't turn up in backtraces.)

1441 Extract the lookup closure from an environment.
1442 (scm_system_module_env_p): New function: Return non-#f if MODULE
1445 * stacks.c: #include "eval.h"; #include "procprop.h";

1448 * debug.c (scm_procedure_name): Use name property in the default
1451 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
1453 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1455 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1456 procedure throughout.
1458 * print.c (scm_iprin1): Removed extraneous space when printing
1459 procedure-with-setters.
1461 Entity and operator setter slots were introduced as a complement
1462 to the <procedure-with-setter> type in order to support entities
1463 and operators with setters in a reasonable and efficient way.
1464 * procs.c (scm_procedure, scm_setter): Handle entity and operator
1467 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

1479 * objects.h (SCM_OBJ_CLASS_REDEF): New macro: Find class slots
1480 directly through the instance.
1482 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1484 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1485 scm_struct_i_flags instead of scm_vtable_index_layout!
1487 * list.c (scm_list_star): New procedure.
1489 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1519 (scm_init_readline): Call init_bouncing_parens.

1556 indicating calling subr, error message text, reason for error,
1557 symbol name or feature name are now pointer to const.
1558 * snarf.h (SCM_PROC, SCM_PROC1): String variables are now const.
1560 * procs.c (scm_init_iprocs): iproc argument now points to const.
1561 * pairs.c (cxrs): Now const.
1563 * chars.h, error.h, feature.h, filesys.h, gc.h, gsubr.h, macros.h,
1564 numbers.h, options.h, procs.h, ramap.h, read.h, smob.h,
1565 strports.h, symbols.h, unif.h: Update variable declarations and
1566 function prototypes for above changes.

1569 sysdep_dynl_unlink, sysdep_dynl_func): Arguments FNAME, SUBR, and
1570 SYMB now point to const.
1572 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1574 * print.c (scm_iprin1): Use scm_procedure_name instead of
1575 scm_procedure_property for compiled closures.
1577 * tags.h (scm_tc7_pws): New procedure type. Four representations
1578 for procedure-with-setters were considered before selecting this
1581 1. A closure where the CODE and ENV slots are used to represent
1582 the getter and a new SETTER slot is used for the setter. The
1583 original getter is stored as a `getter' procedure property. For
1584 closure getters, the CODE and ENV slots contains a copy of the
1585 getter's CODE and ENV slots. For subr getters, the CODE contains
1588 2. A compiled closure with a call to the getter in the cclo
1589 procedure. The getter and setter are stored in slots 1 and 2.
1591 3. An entity (i.e. a struct with an associated procedure) with a
1592 call to the getter in the entity procedure and the setter stored
1593 in slot 0. The original getter is stored in slot 1.
1595 4. A new primitive procedure type supported in the evaluator. The
1596 getter and setter are stored in a GETTER and SETTER slot. A call
1597 to this procedure type results in a retrieval of the getter and a
1598 jump back to the correct eval dispatcher.
1600 Representation 4 was selected because of efficiency and
1603 Rep 1 has the advantage that there is zero penalty for closure
1604 getters, but primitive getters will get considerable overhead
1605 because the procedure-with-getter will be a closure which calls
1608 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1609 <procedure-with-setter>, but together with rep 2 it suffers from a
1610 three level dispatch for non-GOOPS getters:
1612 cclo/struct --> dispatch proc --> getter
1614 This is because the dispatch procedure must take an extra initial
1615 argument (cclo for rep 2, struct for rep 3).
1617 Rep 4 has the single disadvantage that it uses up one tc7 type
1618 code, but the plan for uniform vectors will very likely free tc7
1619 codes, so this is probably no big problem. Also note that the
1620 GETTER and SETTER slots can live directly on the heap, using the
1621 new four-word cells.
1623 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,
1624 SCM_SETTER): New macros.
1625 (scm_procedure_with_setter_p, scm_make_procedure_with_setter,

1650 * eval.h: Declare scm_s_set_x, scm_sym_set_x;
1652 * eval.c: Renamed "set" --> "set_x" in various names for
1653 consistency of name correspondence between Scheme and C;
1654 Renamed scm_i_set_x --> scm_sym_set_x and made global.
1655 Renamed s_set_x --> scm_s_set_x and made global.
1657 1999-01-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1659 * random.c (scm_i_random_bignum): Made independent of endianness.

1677 scm_rstate from seed.
1678 (scm_copy_random_state, scm_seed_to_random_state): New functions.
1679 (scm_make_random_state): Removed.
1681 * random.c (scm_make_random_state): Use scm_i_make_rstate().

1685 * random.c: Bugfix: Retrieve and store most significant 32 bits in
1686 different order if the machine is bigendian.

1689 1999-01-11 Roland Orre <mdj@mdj.nada.kth.se>
1691 * sort.c (scm_merge, scm_merge_list_x): Bugfix: Place elements
1692 from first arg before equal elements in second arg in result.
1693 (scm_merge_list_step): Bugfix: Don't presume that arguments in a C
1694 function call are executed in a well defined order.
1696 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
1698 * alloca.c (alloca): Cast value returned by malloc. (Thanks to
1701 1999-01-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1703 * random.c: Removed alloca includes.
1705 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
1707 * Makefile.in: This changed, for some reason I don't really
1708 understand, when I ran automake in the top level directory. This
1709 may be contamination by Cygnus internal releases. If you re-run
1710 automake and this change gets reverted, don't worry about it.
1712 1999-01-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1714 * sort.c, sort.h: New files: Implement slib's and scsh's sort
1715 interfaces. Author: Roland Orre.

1725 Renamed s_bignum --> scm_s_bignum.
1727 * random.c, random.h: New files: Random number support.
1728 Interface same as slib's.
1730 * Makefile.am: Added random.c, random.h, random.x.
1732 * init.c: #include "random.h";
1733 (scm_boot_guile_1): Call scm_init_random ().
1735 1998-12-23 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1737 * Makefile.am: New files: guardians.c, guardians.x, guardians.h
1739 * guardians.c, guardians.h (scm_make_guardian,
1740 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
1741 scm_get_one_zombie, scm_init_guardian): This is an implementation
1742 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
1743 David Eby (1993) "Guardians in a Generation-Based Garbage
1744 Collector" ACM SIGPLAN Conference on Programming Language Design
1745 and Implementation, June 1993 ftp://ftp.cs.indiana.edu
1746 /pub/scheme-repository/doc/pubs/guardians.ps.gz
1747 Author: Michael N. Livshin.
1749 * gc.h (SCM_MARKEDP, SCM_NMARKEDP): New macros.
1751 * gc.c (scm_igc): Call scm_guardian_gc_init and
1752 scm_guardian_zombify.

1756 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1758 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
1761 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1763 Move the procedure slots of entities to invisible slots (so that
1764 we can have operator class objects which themselves are entities).
1765 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
1766 SCM_STRUCTF_ENTITY): New constants.
1768 * struct.c (scm_make_struct): Allocate "invisible" room for
1769 procedures if SCM_STRUCTF_ENTITY is set in vtable.
1771 * gc.c (scm_gc_mark): Mark entity procedures.
1773 * struct.c, struct.h (scm_alloc_struct): Renamed from alloc_struct

1778 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
1779 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
1781 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
1783 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
1784 of syntactic forms, similar to SCM_PROC.
1785 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
1786 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
1787 for the name symbols when needed.
1789 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
1791 * Makefile.in: Regenerated.
1793 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
1795 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
1796 take the address of _into; it might be a register. Just have
1797 scm_debug_newcell return the new cell.
1798 * gc.c (scm_debug_newcell): Just return the new cell, instead of
1799 taking the address of a place to store it as an argument.
1800 * gc.h (scm_debug_newcell): Change declaration.
1801 (Thanks to Greg Harvey.)
1803 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1805 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
1806 Replaces old names serial-array-copy! and serial-array-map!.

1812 * smob.c (freeprint): New function.
1813 (freecell): Use it to print freed objects, for slightly easier
1816 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1818 * backtrace.c (display_frame): Made more robust. Doesn't throw an
1819 error if no source properties can be found for a frame. (Thanks
1820 to Christian Lynbech.)
1822 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1824 * objects.h: Removed slots direct_supers and direct_slots from the
1825 definitions of the rudimentary classes described by objects.h.
1827 * objects.c, objects.h (scm_entity_p): New procedure. Together
1828 with the predicates scm_procedure_p and scm_struct_p, this
1829 predicate makes it possible to differ between structs, entities
1832 * modules.c, modules.h (scm_resolve_module): New function.
1834 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1836 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
1837 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
1840 * objects.c (scm_entity_p): New procedure.
1842 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
1843 for asubrs, rpsubrs, lsubrs and lsubr_2s.
1845 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1847 * procprop.h (scm_i_procedure_arity): Added declaration.
1849 * procprop.c (scm_i_procedure_arity): Made global; New code to
1850 handle operators and entities.
1851 (scm_procedure_property): No need to call scm_procedure_p since
1852 scm_i_procedure_arity now does all necessary type checking.
1853 Added #include "objects.h".
1855 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
1856 s_add_hook_x --> s_remove_hook_x.
1857 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
1858 Added #include "procprop.h"
1860 * feature.c, feature.h (scm_reset_hook_x): New procedure.
1861 (scm_make_hook): Optional argument defines number of arguments to
1863 (scm_make_named_hook): Take number of args as second arg.
1864 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
1865 boot-9.scm for a while); First arg is the hook. The rest are
1866 arguments passed on to the hook procedures.
1868 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
1870 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
1871 scm_logbit_p): Do the computation in ulongs. This is not as nice
1872 as doing it in bignums, but at least it's good enough for
1873 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
1875 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
1876 subexpressions. (Thanks to Charbel Jacquin.)
1878 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
1880 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
1881 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
1882 (scm_make_named_hook): New function.
1884 * feature.c: Added #include "eval.h".
1886 * modules.c (scm_make_module): Beautify the module.
1888 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1890 * modules.c, modules.h: New files: C interface to modules. (This
1891 is necessary in order to interface the object system to Guile
1892 properly. The guts of these modules will be replaced by the new
1893 module system in the future.)
1895 * init.c: Added #include "modules.h"
1896 (scm_boot_guile_1): Call scm_init_modules.
1897 (invoke_main_func): Call scm_post_boot_init_modules.
1899 * Makefile.am: Added modules.c, modules.x, modules.h.
1901 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
1903 * procs.c: #include "objects.h"
1904 (scm_procedure_p): Return #t also on structs which are operators.
1906 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
1907 <operator-metaclass> and <entity-class> to <standard-class>,
1908 <operator-class> and <entity> in order to conform with STKlos
1911 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
1912 which isn't an operator.
1913 (SCM_APPLY): Ditto, but jump to badproc.
1915 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
1917 * eval.c (SCM_CEVAL): Allow structs implanted in code.
1918 Previously, structs implanted in code were interpreted as forms
1919 the operator of which was a gloc. We solve this by checking for
1920 the zero in the emulated vcell in the struct vtable. Since
1921 implanted structs always will look like forms with a gloc
1922 operator, execution will only be slowed down by maximally one
1923 extra test-and-branch per application.
1925 * evalext.c (scm_definedp): Removed check for isyms; Added a
1926 second optional argument: It is now possible to supply an
1927 evaluation environment in which to look for the symbol.
1929 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1931 * readline.c (scm_init_readline): Set
1932 rl_basic_word_break_characters. (Thanks to Ian Grant.)
1934 * coop.c (coop_condition_variable_wait): Removed
1935 (coop_condition_variable_wait_mutex): Folded logic of
1936 coop_mutex_unlock into coop_condition_variable_wait_mutex to
1937 prevent condvar signal lossage. Previously, another thread could
1938 start to run after unlocking the mutex but before putting the
1939 current thread on the wait queue. If that thread then would
1940 signal the first, the signal would be lost. (Thanks to Christian
1943 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1945 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
1948 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1950 * objects.c (scm_i_make_class_object): Renamed from
1951 make_class_object; exported; error checking moved to
1952 scm_make_class_object and scm_make_subclass_object.
1953 (scm_make_class_object, scm_make_subclass_object): Use
1954 scm_i_make_class_object.
1955 (scm_make_subclass_object): Let the subclass have same metaclass
1958 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1960 * debug.c (scm_debug_options): Bugfix: Set the value of
1961 scm_stack_checking_enabled_p after setting debug options;
1962 #include "stackchk.h". (Thanks to Richard Polton.)
1964 1998-11-13 Radey Shouman <rshouman@metro2000.com>
1966 * unif.c (scm_array_contents): removed unnecessary test for 0
1969 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1971 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
1972 Replaced by macro `collect' in boot-9.scm.
1974 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1976 * eval.c (scm_copy_tree): Copy source properties if existent.
1978 * debug.c (scm_start_stack): Copy source when evaluating. (If we
1979 don't, we may end up passing memoized source to a transformer.)
1981 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1983 * stack.c (get_applybody): Help function which lookups the first
1984 body form of the apply closure.
1985 (read_frames): Prevent the source of the first form of the apply
1986 closure from being recorded. This would only be confusing.
1988 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
1989 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
1991 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
1993 * stacks.c (read_frame): Bugfix: Removed lingering `else'
1995 (read_frames): Use SCM_MACROEXPP.
1997 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1999 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
2000 don't contain interesting information since all arguments are
2001 present in the frame which applies the compiled closure anyway.);
2002 Skip the transformer application frames.
2004 * print.c (scm_iprin1): Print gsubrs as primitives.
2006 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2008 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
2010 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
2011 that we can identify these in a backtrace. (This change doesn't
2012 introduce any significant speed penalty.)
2014 * eval.c: Added note about `serial-map' using scm_map.
2016 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2017 readline options. They should reside in their own options array.
2019 * readline.c, readline.h (scm_readline_options,
2020 scm_readline_opts): Moved readline options here.
2022 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2024 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2025 SCM_ROCHARS instead of SCM_CHARS.
2027 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2028 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2030 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2032 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2033 This is quite important since the latter clears the
2034 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2035 every single character read...
2037 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2039 * print.c (scm_iprin1): Removed suspect looking (and indeed
2040 malevolent) semicolon after test for user supplied closure print
2041 procedure. (Thanks to Telford Tendys.)
2043 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2044 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2045 starting to search the list. Removed call to sloppy_mem_check.
2047 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2048 procedures: Same as scm_delq_x et al, but delete maximally one
2051 * options.c (scm_options, scm_init_options): GC-protect option
2052 values of type SCM. (Thanks to Telford Tendys.)
2054 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2056 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2057 make sure that there always is a "real" scm_lookupcar.
2059 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2061 * read.c, read.h (scm_read_opts): New read options
2062 "history-length" and "history-file".
2063 (scm_read_options): Stifle history to history length.
2065 * readline.c (scm_read_history, scm_write_history): New procedures.
2067 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2069 * eval.h (scm_macro_eval_x): Removed declaration.
2071 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2072 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2073 Renamed and made global.
2075 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2076 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2078 * evalext.c, evalext.h: New files. Contain non-R5RS things
2079 having to do with evaluation.
2081 * evalext.c (scm_serial_map): New procedure: Version of `map'
2082 which guarantees that the procedure is applied to the lists in
2084 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2085 returns a list of the results of the body forms instead of the
2086 result of the last body form.
2087 (scm_definedp, scm_m_undefine): Moved from eval.c
2089 * evalext.h (scm_m_sequence_to_list): Added declaration.
2091 * macros.c, macros.h: New files.
2092 (scm_procedure_to_syntax, scm_procedure_to_macro,
2093 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2094 scm_macro_name, scm_macro_transformer): Moved from eval.c
2095 (scm_make_synt): Moved from eval.c
2097 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2099 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2102 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2104 * debug.c, print.c: Added #include "macros.h".
2106 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2108 This change adds the ability to use `unread-char' multiple times
2109 without interspersed reads and adds the new procedure
2110 `unread-string'. The change is optimized for the common case of
2111 unreading a single character. This is also the reason behind the
2112 choice to store characters in the port itself: in most cases no
2113 extra malloc is required.
2115 The amount of code in some macros in ports.h has been increased to
2116 the extent that they would fit better as C functions, but, since
2117 this code belongs to the port representation, such functions
2118 should be placed in ports.c which would cause calls back and forth
2119 between ports.c and genio.c. That is not good for performance.
2120 Also, keeping them as macros allows the compiler to do some
2121 optimizations which are needed to make the current interface
2122 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2124 One benchmark (Guile startup time) indicates an increase of
2125 loading speed of 1%. Another (reading (using `read') boot-9.scm
2126 10 times) shows no change in performance.
2128 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2129 made to find a beautiful solution.)
2131 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2132 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2133 character. (SCM_CLRDY clears all.)
2134 (SCM_N_READY_CHARS): New macro: Returns number of unread
2135 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2136 (struct scm_port_table): New fields: `entry' contains port table
2137 index, `cp' points to last unread char, `cbuf' is the buffer for
2138 unread chars, `cbufend' points after end of the character buffer.
2140 * ports.h, ports.c (scm_unread_string): New procedure.
2141 (scm_grow_port_cbuf): New function.
2143 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2145 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2146 to read unread characters. Use SCM_TRY_CLRDY instead of
2149 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2151 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2153 * genio.c, genio.h (scm_ungets): New function.
2155 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2158 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2160 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2161 declarations. (Thanks to Russ McManus.)
2163 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2165 * numbers.c (num2long): As a software archeologist, I'm proud of
2166 this finding! :) Preliminary dating suggests an almost 4 year old
2167 remnant from the SCM ancestor. The sample has been removed from
2168 the finding site and is now safely stored in the repository.
2170 * numbers.h: Removed prototype for num2long.
2172 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2174 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2175 array as second arg.
2176 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2177 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2178 * gh.h: Updated and added prototypes.
2180 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2182 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2184 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2186 * guile-snarf.in: Never generate an empty file. (Thanks to
2189 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2190 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2191 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2192 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2193 gh_new_procedure5_0): Specify argument types, to appease C++
2194 compilers. (Thanks to Brad Bowman.)
2196 Bug reports from Russ McManus:
2197 * guile-snarf.in: If the CPP environment variable is set, use that
2198 as the C preprocessor, instead of the preprocessor autoconf
2200 * snarf.h (SCM_PROC): Cast the function pointer passed to
2201 scm_make_gsubr, to satisfy C++.
2203 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2204 Use the handler passed, instead of ignoring it and using
2205 gh_standard_handler. (Thanks to Etienne Bernard.)
2207 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2209 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2212 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>

2229 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
2232 * script.c (scm_compile_shell_switches): Define
2233 use-emacs-interface in the root module, so the repl code can see
2234 it. See today's change to top-repl in ice-9/boot-9.scm.
2236 * filesys.c (set_element, get_element): Make sure that `element'
2237 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2238 Boekemeier and Jorgen "forcer" Schaefer.)
2240 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2242 * chars.c (scm_charnames): In ASCII character name table, make
2243 newlines print as #\newline by default, not #\nl.
2245 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2246 alphabetical order. Oh thrills. But it helps me know how far
2247 along in the compilation I am.
2248 * Makefile.in: Regenerated.
2250 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2252 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2253 #bytes(...) to #y(...), and syntax for short vectors from
2254 #short(...) to #h(...). This may seem nutty, but, like the other
2255 uniform vectors, byte vectors and short vectors want to have the
2256 same print and read syntax (and, more basic, want to have read
2257 syntax!). Changing the read syntax to use multiple characters
2258 after the hash sign breaks with the conventions used in R5RS and
2259 the conventions used for the other uniform vectors. It also
2260 introduces complexity in the current reader, both on the C and
2261 Scheme levels. (The Right solution is probably to change the
2262 syntax and prototypes for uniform vectors entirely.)
2264 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2266 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2267 (Thanks to Jorgen "forcer" Schaefer.)
2268 * ports.h (SCM_NOFTELL): New flag.
2269 * fports.c (local_fgets): If it's set, use the generic fgets.
2270 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2272 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2274 * script.c (scm_compile_shell_switches): Add handling of -q switch
2275 (inhibit loading of user init file).
2276 (scm_shell_usage): Add usage text for -q switch.
2277 (scm_compile_shell_switches): Always load user init file first if
2278 it is loaded at all.
2280 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2282 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2283 and is now broken under NetBSD. I can't fathom what it's trying
2284 to do, so I've replaced it with something that I do understand,
2285 which seems to work, and which isn't broken on NetBSD. "Progress?
2286 You Decide." (Thanks to Perry Metzger.)
2288 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2289 signed/unsigned comparison.
2291 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2293 Warning fixes from Greg Harvey:
2294 * unif.c (scm_array_set_x): initializer for pos
2295 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2296 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2297 initializers for field_type, since EGCS so desparately wants to
2299 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2300 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2301 when GUILE_DEBUG is defined.
2302 * dynwind.h (scm_wind_chain): Same.
2303 * ports.h (scm_pt_size, scm_pt_member): Same.
2304 * print.h (scm_current_pstate): Same.
2305 * procs.h (scm_make_cclo): Same.
2307 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2309 Handle short and long long uniform arrays properly. (Thanks to
2311 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2312 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2313 scm_tc7_llvect (long long vectors).
2315 Change the way libguile and boot-9.scm are timestamped, to try to
2316 get rid of these spurious mismatch warnings. Now both
2317 libguile/versiondat.h and ice-9/version.scm are generated directly
2318 by the configuration process, rather than having version.scm
2319 generated directly, and libguile/versiondat.h generated by the
2320 Makefile, which is generated by configure. It seems that
2321 sometimes the Makefile would change, but versiondat.h depends on
2322 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2323 * Makefile.am (versiondat.h): Target removed; this is generated
2324 directly by the configure script now.
2325 (BUILT_SOURCES): Remove versiondat.h.
2326 * versiondat.h.in: New file, transformed by the configure script
2328 * Makefile.in: Regenerated.
2330 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2331 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2332 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2333 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2334 if we want to use them in a header file some day, we can. (Thanks
2335 to Michael Livshin.)
2337 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2338 SCM numbers, so we won't have rollover problems; the range of a
2339 signed long in milliseconds is about 25 days. (Thanks to Karl
2342 Don't redefine sleep and usleep; fix this problem now.
2343 * coop.c (sleep, usleep): Remove declarations; we don't use or
2344 redefine these any more.
2345 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2346 job of usleep and sleep in a thread-friendly way. We can use
2347 these in the rest of Guile. Define versions for systems both with
2348 and without iselect.
2349 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2350 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2351 we're just using it, not redefining it, we can use a K&R style
2353 (sleep): Declare this, too, if the system hasn't.
2354 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2355 scm_uthread_sleep if they're available; otherwise, just call the
2357 * scmconfig.h.in: Regenerated.
2359 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2361 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2363 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2365 * threads.c: Doc fix.
2367 The argument type of usleep varies from system to system,
2368 as does the return type. We really shouldn't be redefining usleep
2369 at all, but I don't have time to clean that up before the 1.3.
2370 release. It's on the schedule for afterwards. (Thanks to Julian
2372 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2374 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2375 * scmconfig.h: Regenerated.
2377 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2378 right way to handle system variation. Autoconf's approach is the
2380 * simpos.h (scm_software_type): Declaration deleted.
2382 * script.c (scm_find_executable): Don't test if unix is #defined
2383 here; first, NetBSD doesn't #define it, and second, it's the wrong
2384 way to go about these things. (Thanks to Perry Metzger.)
2385 (dld_find_executable): Delete this MSDOS support code. This isn't
2386 the way we want to support this; it needs to be rethunk at a
2389 * genio.c (scm_do_read_line): Don't just politely check that the
2390 line was either non-empty or EOF. Abort if it's empty and not
2393 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2395 * scmconfig.h.in: Regenerated.
2397 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2400 * genio.c (scm_do_read_line): Count lines correctly when the file
2401 doesn't end in a newline.
2403 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2405 * genio.c (scm_do_read_line): Maintain the line count correctly.
2406 (Thanks to Harvey J. Stein and Greg Harvey.)
2408 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2411 * numbers.c (big2str): Protect t from garbage collection until
2412 we're done. (Thanks to Gary Houston.)
2414 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2416 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2418 * Makefile.in: Regenerated.
2420 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2421 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2424 Do magic to mix reads and writes on stdio FILE-based ports.
2425 (Thanks to Christian Lynbech.)
2426 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2428 (pre_read, pre_write): New functions.
2429 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2430 local_fputs): Call them.
2431 (local_fflush): Mark the port as ready for reading and writing.
2432 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2433 flags on new port objects. This might not be accurate --- who
2434 knows what state the FILE * is in when we get it --- but it won't
2435 do extraneous calls to fflush or fseek, so it's no worse than the
2436 behavior before this change.
2437 * ports.h: Add comment.
2439 Centralize the creation of port objects based on stdio FILE * in
2440 fports.c; don't just throw them together anywhere.
2441 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2442 what the rest of Guile wants. Don't set the revealed count;
2443 that's only appropriate for stdin, stdout, stderr.
2444 (scm_standard_stream_to_port): This function does set the revealed
2446 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2447 not scm_stdio_to_port.
2448 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2449 * fports.c (scm_open_file): Same.
2450 * posix.c (scm_pipe): Same.
2451 * socket.c (scm_sock_fd_to_port): Same.
2452 * ioext.c (scm_fdopen): Same.
2453 (scm_freopen): Moved from here to...
2454 * fports.c (scm_freopen): ... here. This is really something that
2455 munges the internals of an fport, so it should go here.
2456 * fports.h (scm_stdio_to_port): Adjust prototype.
2457 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2458 * ioext.h (scm_freopen): Prototype removed.
2460 * filesys.c (set_element, get_element): This can work on both pipe
2461 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2464 * scmconfig.h.in: Regenerated.
2466 Change the definition of the functions in scm_ptobfuns so that
2467 they get passed the port object, not the port's stream.
2468 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2469 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2470 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2471 Pass the port itself to the scm_ptobs function.
2472 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2473 scm_generic_fgets): Same.
2474 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2475 getc_void_port, fgets_void_port, close_void_port): Just change the
2476 argument names; these functions don't really do anything.
2477 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2478 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2479 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2480 Also, use prototyped definitions, and get rid of the extra
2482 (scm_fptob, scm_pipob): We don't need casts here any more.
2483 * strports.c (prinstpt): Use prototype declarations.
2484 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2485 and use SCM_STREAM to get the string info. Also, use prototyped
2486 definitions, and get rid of the extra declarations.
2487 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2490 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2491 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2493 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2494 scm_fgets, for consistency.
2495 (scm_fptop, scm_pipob): References updated.
2497 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2499 Include the source location in error messages for scripts.
2500 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2501 stack is still there when we catch the error.
2502 * throw.c (handler_message): If we are handling an error with a
2503 message, then put together the proper arguments and call
2504 scm_display_error, instead of scm_display_error_message. That
2505 displays source location, if it can find it.
2507 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2509 * gc.c (scm_unprotect_object): Change this so that calls to
2510 scm_protect_object and scm_unprotect_object nest properly.
2511 (scm_protect_object): Doc fixes.
2513 * strings.c (scm_string_set_x): Require the argument to be a
2514 writable string, not a substring or a symbol.
2515 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2516 (Thanks to John Redford and Charbel Jacquin.)
2518 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2520 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2522 * eval.c (safe_setjmp): Remove this misunderstanding.
2523 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2526 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2528 * libguile.h: Mark these as C declarations, for compilation by C++
2531 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2532 __cplusplus clause. I seriously doubt this ever worked the way
2533 the author seems to have intended.
2535 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2537 Utterly needless cleanups to hopelessly messy code.
2538 * ports.c: Doc fixes.
2539 (scm_fflush): Moved to ...
2540 * genio.c (scm_fflush): ... here, amongst all the other port
2541 method invocation functions.
2542 * genio.h, ports.h: The prototype moves too.
2544 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2546 * backtrace.c (display_error_body): The current frame does not
2547 always have a parent frame; consider a function called directly
2548 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2551 * alloca.c (alloca): Undo yesterday's changes, and simply call
2552 malloc directly for storage, and abort if we don't get what we
2553 want. The situation is much simpler --- just call malloc. Emacs
2554 has bizarre/evil requirements (signal handlers might malloc unless
2555 you set this global flag, so you have to set the flag around all
2556 calls to malloc) which we are certainly not going to conform to,
2557 so we can do the simple and obvious thing.
2559 * coop.c (coop_condition_variable_wait): Make this function
2560 static. It's only useful internally --- you should never just
2561 wait on a condition variable.
2562 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2564 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2566 * unif.c (scm_array_set_x): Accept any kind of number as an
2567 element for a uniform vector of doubles. This is more consistent
2568 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2570 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2571 works; I can't conveniently test it myself. (Thanks to Dvid
2572 Tillman for the bug report.)
2574 * init.c: Doc fixes.
2576 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2577 from here, not from scm_compile_shell_switches (which is a pretty
2578 dumb place to do it).
2579 (scm_load_startup_files): New function.
2580 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2581 * script.c (scm_compile_shell_switches): Don't load the startup
2583 (scm_ice_9_already_loaded): Variable moved.
2584 * init.c (scm_load_startup_files): Prototype for new function.
2585 * gh_init.c (gh_enter): Doc fix.
2587 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2589 Some anti-warning changes from Greg Harvey.
2590 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2591 warnings when it doesn't understand our NORETURN declarations in
2593 * posix.c (scm_mknod): Similar.
2595 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2597 * posix.c (scm_getpwuid): If we can't find an entry, return our
2598 own message, instead of using scm_syserror --- the getpwMUMBLE
2599 functions don't set `errno' to anything interesting.
2601 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2603 Get rid of warnings from the cooperative threading system.
2604 * threads.h (scm_single_thread_p, scm_yield,
2605 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2606 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2607 scm_wait_condition_variable, scm_signal_condition_variable): Add
2608 prototypes for these Scheme-visible functions.
2609 * coop-defs.h (coop_next_runnable_thread,
2610 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2611 Prototypes for these here, even though they're from iselect.c.
2612 (coop_condition_variable_wait, coop_join): Add prototypes.
2613 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2614 scm_threads_free_condvar): Make these smob functions static.
2615 * coop-threads.h (coop_init): Give this a real prototype.
2616 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2617 (coop_next_runnable_thread): No need to provide prototype; it's in
2620 * scmconfig.h.in: .detarenegeR
2622 * iselect.c, threads.c: Doc fixes.
2624 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2626 * Makefile.in: Regenerated with a patched automake, to get
2627 dependency generation right when using EGCS.
2629 * inet_aton.c (inet_aton): Add prototype, to remove compiler
2630 warning. (Thanks to Robert Pluim.)
2632 * inet_aton.c (inet_aton): Reassure the compiler that the
2633 arguments to the <ctype.h> macros are all unsigned characters, not
2636 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2638 Getting rid of more warnings...
2639 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
2640 today's change to ../configure.in.
2641 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
2642 * scmconfig.h.in: Regenertaded.de.,.__
2643 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
2644 (scm_localtime, scm_mktime): Use a const char * to manipulate the
2647 * readline.c: Doc fix.
2648 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
2649 * readline.h (scm_filename_completion_function): Add prototype.
2650 (scm_init_readline): Make this into a prototype.
2652 * readline.c (scm_filename_completion_function): Use SCM_PROC to
2653 declare this, instead of calling scm_make_subr manually.
2655 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
2657 * readline.h (scm_init_readline): Add prototype for this.
2658 (scm_init_readline): Make this a real prototype.
2660 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
2662 Warning fixes from Maciej Stachowiak:
2663 * backtrace.h (scm_display_application, scm_backtrace): Add
2665 * debug.c (scm_m_start_stack): Make this function static.
2666 * fluids.h (scm_fluid_p): Add prototype.
2667 * procprop.c (scm_i_procedure_arity): Make this function static.
2668 * regex-posix.c (scm_regexp_error_msg): Make this function static.
2669 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
2670 * root.h (scm_dynamic_root): Add external prototype.
2671 * scmsigs.h (scm_usleep): Add external prototype.
2672 * script.h (scm_init_script): Use prototype, not K&R decl.
2673 * stacks.h (scm_stack_id): Add external prototype.
2674 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
2676 1998-09-30 Mark Galassi <rosalia@cygnus.com>
2678 * gh.h: took out the definitions of vset and vref, since they are
2679 replaced by the proper vector routines that correspond to the R4RS
2682 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
2684 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
2685 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
2686 third argument, a C expression that should result in a SCM value,
2687 which is used to initialize the variable. Reimplemented
2688 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
2691 * version.h (scm_libguile_config_stamp): Add prototype.
2692 (From Maciej Stachowiak.)
2694 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
2696 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
2697 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
2699 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
2701 * print.c (scm_iprin1): Rather than having one i, and using it in
2702 several places, declare a fresh i local to each block where it is
2703 used, and give it a signedness appropriate to its use in each case.
2704 (scm_iprlist): Same.
2706 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
2707 comparison warnings.
2709 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
2710 signed/unsigned clashes.
2712 * posix.h (scm_tmpnam): Added prototype.
2714 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
2715 scm_make_subclass_object): Add external prototypes.
2717 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
2718 comparison is okay here.
2720 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
2722 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
2723 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
2725 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
2728 * load.c (swap_port): Make this function static.
2730 * load.c (scm_search_path): Make max_path_len and max_ext_len
2731 unsigned, since they're compared against string sizes.
2733 * load.c (init_build_info): Make i unsigned.
2735 * ioext.h (scm_read_line): Add prototype.
2737 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
2738 scm_hash_fn_remove_x): Make hash bucket index local variable k
2739 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
2740 accurately as possible.
2742 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
2743 comparisons, and range checking to make sure those casts are
2746 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
2747 signed/unsigned comparisons.
2749 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
2750 avoid signed/unsigned comparisons.
2751 * smob.h (scm_numsmob): Change extern declaration to match.
2753 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
2754 avoid signed/unsigned comparisons.
2755 * ports.h (scm_numptob): Change extern declaration to match.
2756 (scm_current_load_port, scm_set_port_line_x,
2757 scm_set_port_column_x): New prototypes.
2759 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
2760 test code, and it causes warnings.
2762 * gh.h (gh_int2scmb, gh_uniform_vector_length,
2763 gh_uniform_vector_ref): Added prototypes.
2765 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
2766 debugging support unconditionally. That's backtrace.c, stack.c,
2767 debug.c, and srcprop.c.
2768 (EXTRA_libguile_la_SOURCES): Omit those from here.
2769 * Makefile.in: Regenerated.
2771 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2773 * options.c (scm_options): Bugfix: Allow empty list of options!
2775 * debug.c, debug.h (scm_single_step): Removed.
2776 (scm_with_traps): New procedure. This procedure could easily be
2777 written in Scheme but needs to be highly optimized.
2779 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
2781 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
2782 Check SCM_TRAPS_P before trapping.
2784 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
2786 Changes to avoid signed/unsigned comparison warnings.
2787 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
2788 (scm_gc_sweep): Make n and j local to the blocks they're used in,
2789 so they can have appropriate types for each application. Make i
2790 signed. Use initializers in some spots. I'll probably pay for
2792 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
2793 (scm_must_realloc): Make nm unsigned.
2794 (init_heap_seg): Make new_seg_index and n_new_objects signed.
2795 (scm_init_storage): Use prototype-style definition, and make the
2797 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
2798 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
2800 * filesys.c (scm_readlink): Make local vars rv and size ints, to
2801 avoid signed/unsigned comparison warnings, and because the return
2802 value of readlink may be -1. Don't bother casting the third
2803 argument to readlink.
2805 * filesys.c (scm_dirname, scm_basename): Move these to their own
2806 page, at the end of the file.
2807 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
2809 * eval.h (scm_eval_options_interface): Add external prototype for this.
2810 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
2812 * eval.c (scm_lookupcar1): Make this static.
2814 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
2815 Make these prototype declarations, not K&R-style.
2817 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
2818 unsigned comparison warning.
2820 * appinit.c: File removed. It had a single function in it, empty,
2821 whose reason for existence is explained in no documentation or
2822 comment. I think it's there as a default for some Tcl-style
2823 initialization, but Tcl abandoned that approach a while ago.
2824 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
2825 (BUILT_SOURCES): Remove appinit.x.
2826 * Makefile.in: Regenerated.
2828 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
2830 * Makefile.in: Regenerated using the last public version of
2831 automake, not the hacked Cygnus version.
2833 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
2835 Remove Totoro kludge.
2836 * Makefile.in, scmconfig.h.in: Regenerated.
2837 * init.c, readline.c: Don't check if TOTORO is #defined.
2839 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
2841 * Makefile.am: Adjust for new thread configuration system.
2842 (INCLUDES): Include the value of THREAD_CPPFLAGS.
2843 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
2845 (THREAD_LIBS): Definition deleted; automake will generate such
2846 things automatically.
2847 * Makefile.in: Regenerated.
2849 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
2851 Simplify smob and port marking; set the mark bit in the generic
2852 marking code, and make marker routines only responsible for
2853 turning up outgoing pointers.
2854 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
2855 before calling the marking function. Don't call the marking
2856 function if it's zero.
2857 * markers.c (scm_mark0): Just return #f. This function isn't
2858 necessary at all now, but it's harmless to call it. We'll leave
2859 it in so other folks' code doesn't croak at link time.
2860 (scm_markcdr): Don't call SCM_SETGC8MARK.
2861 * async.c (mark_async): Don't call SCM_SETGC8MARK.
2862 * dynl.c (mark_dynl_obj): Same.
2863 * root.c (mark_root): Same.
2864 * srcprop.c (marksrcprops): Same.
2865 * unif.c (markra): Same.
2866 * variable.c (scm_markvar): Same.
2867 * ports.c (scm_markstream): Same.
2868 (void_port_ptob): Specify zero for our marking function.
2869 * debug.c (debugobjsmob): Same.
2870 * dynwind.c (guardsmob): Same.
2871 * filesys.c (dir_smob): Same.
2872 * fluids.c (fluid_smob): Same.
2873 * fports.c (scm_fptob, scm_pipob): Same.
2874 * mallocs.c (mallocsmob): Same.
2875 * regex-posix.c (regex_t_smob): Same.
2876 * smob.c (freecell, flob, bigob): Same.
2877 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
2878 * throw.c (jbsmob, lazy_catch_funs): Same.
2880 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2882 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
2883 scm_copy_tree on code in order not to let memoized code to leak
2884 out. Thus, scm_copy_tree needs to copy vectors as well since
2885 quasiquote can introduce evaluated code also inside vector
2888 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2890 * eval.c (scm_copy_tree): Removed ability to copy vectors.
2892 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
2893 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
2896 * unif.c: Say that ivect and uvect are of type signed and unsigned
2897 long instead of int in commentary so that it correctly describes
2900 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2902 * stime.c: Removed declaration of strptime. (It should be
2903 declared by the system headers. If it turns out that some systems
2904 don't, we'll handle that then.) (Thanks to Greg Troxel.)
2906 * stime.h: Renamed TIMEH --> STIMEH
2908 * backtrace.c (scm_display_error, scm_display_backtrace): In order
2909 to increase portability, don't use structure assignment.
2910 (Thanks to Nicolas Neuss.)
2912 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
2914 (finalize_fd_sets): Added empty statement after last case label.
2915 (Thanks to Nicolas Neuss.)
2917 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
2920 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
2922 * init.c, readline.c: OK, I won't have these readline.x bug
2923 reports anymore. We've had them since April. The current reason
2924 is a completely unintelligible failure of totoro.red-bean.com to
2925 do the test for rl_getc_function in libreadline correctly. This
2926 kludge overrides the test if we're on totoro so that the snapshot
2927 generation process can work.
2929 * readline.c: Define a strdup replacement if not existent on system.
2931 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2933 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
2934 This change makes scm_make_vector R5RS compatible. We cannot keep
2935 the third argument since people want to be able to deduce the form
2936 of the C function call only by looking at R5RS. (At the same time
2937 we have removed some unnecessary complexity!)
2939 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
2940 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
2941 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
2942 argument in call to scm_make_vector.
2944 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2946 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
2947 This macro is useful in applications.
2949 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2951 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
2952 (scm_parse_path, scm_search_path): New Scheme level procedures.
2954 * load.h (scm_internal_parse_path, scm_parse_path,
2955 scm_search_path): Declared.
2957 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2959 * filesys.c (dirname, basename): New procedures.
2961 * init.c (scm_boot_guile_1): Removed condition around
2964 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
2965 new data type (guards) for representation of C level guards and
2966 data on the wind chain.
2967 (scm_internal_dynamic_wind): New function.
2969 * dynwind.h: Declare scm_internal_dynamic_wind.
2971 * root.h (scm_root_state): Added scm_cur_loadp.
2973 * root.c (mark_root): Added comment about cur_loadp.
2975 * load.c: #include "dynwind.h";
2976 (scm_primitive_load): Use scm_inner_dynamic_wind to update
2979 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
2981 * ports.c (current-load-port): New procedure.
2983 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2985 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
2986 not a tty, return #f.
2988 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
2989 to Julian Satchell and Roland Kaufmann.)
2991 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
2992 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
2994 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2996 * debug.h, debug.c (scm_start_stack): New function. Implements
2997 the guts of old scm_m_start_stack.
2999 * debug.c (scm_m_start_stack): Use scm_start_stack.
3001 * init.c (scm_start_stack, scm_restart_stack): Renamed to
3002 start_stack and restart_stack. (These have static scope.)
3004 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3006 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
3007 readline functions to come in release 2.3. (Thanks to Chet
3009 (handle_errors): Use the above functions.
3011 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3013 * readline.c: Improvements for readline support: Handle errors
3014 better; Implement before-read-hook.
3016 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3018 * init.c (scm_boot_guile_1), readline.c: Test for
3019 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3020 assure that we have version >= 2.1.)
3022 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3024 * readline.c (scm_readline): Defer interrupts while we're calling
3027 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3028 away the string to add_history.
3029 (completion_function): Do completion for readline. (Thanks to
3031 (scm_filename_completion_function): New procedure: Filename
3033 (current_input_getc): New function. Use this one instead of
3034 standard getc from readline.
3036 * throw.c, throw.h (scm_handle_by_throw): New function: This
3037 handler throws errors to next handler on the dynwind chain.
3039 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3041 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3044 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3046 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3048 (scm_procedure_properties): Modified to return arity together with
3050 (scm_procedure_property): Added the read-only property `arity'.
3051 (scm_set_procedure_property_x): It is an error to set the `arity'
3054 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3055 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3057 * procprop.h (scm_sym_arity): New symbol.
3059 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3060 to set the dispatch procedure of an operator or entity object.
3062 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3063 Made procedure slots read-only.
3065 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3066 scm_tcs_cons_gloc case in zero args switch; Fixed args
3067 construction for operators in scm_tcs_cons_gloc case in two args
3070 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3072 * fluids.c: Removed use of assert.h (in order to avoid
3075 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3077 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3079 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3080 change makes the evaluator safer at the cost of evaluation speed.
3081 It handles the case when the user has added a non-immediate
3082 improper end of the application form, e.g., `(+ 0 . x)'.
3083 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3084 minimize the extra cost as much as possible. The new code is
3085 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3086 problem with structs planted directly in the code (e.g. by a
3087 macro). This no longer causes segmentation fault. (Thanks to
3090 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3091 arg `proc' in order to be able to throw errors; New argument
3094 * Removed extra #include "debug.h"
3096 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3098 * scmsigs.c: Declare usleep as returning void on some systems.
3099 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3102 * coop.c (usleep): Return void on some systems.
3104 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3106 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3108 * coop.c: Changed return type of usleep to int.
3110 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3111 isn't found in the OS.
3113 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3114 isn't enabled. (Thought that I had made this change ages ago...)
3116 * iselect.c: Declare bzero if not defined by OS.
3118 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3120 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3121 condition. (Thanks to John Tobey.)
3123 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3124 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3127 * __scm.h: Start the long-term project of moving to POSIX threads.
3128 Phase 1: Classification of all critical sections.
3129 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3130 for A sections. (See comments in __scm.h for details.)
3132 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3133 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3135 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3137 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3138 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3139 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3140 dependencies on $(srcdir)/Makefile.in
3141 $(top_builddir)/config.status in order to avoid circularity.
3143 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3144 from argc if argc was 0 initially.
3146 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3147 in generation of libpath.h.
3149 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3151 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3152 libguile from 2 to 3.
3154 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3156 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3158 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3160 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3161 scm_set_port_column_x, scm_port_filename,
3162 scm_set_port_filename_x): Removed optional arguments. Added
3163 proper argument checking.
3165 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3166 stack size in machine words.
3168 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3169 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3170 to Ole Myren Röhne.)
3172 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3174 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3175 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3177 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3180 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3181 procedure apply: Copy argument lists before pushing them unto the
3182 environment so that the environment won't get mutated due to
3183 manipulation of procedure arguments. This should perhaps be
3184 regarded as a temporary solution until someone finds a more
3185 efficient one. (Thanks to Maciej Stachowiak.)
3187 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3189 * script.c (scm_compile_shell_switches): Use "guile" as default
3190 zero arg if argc is NULL.
3192 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3194 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3195 is zero. (Thanks to Dirk Herrmann.)
3197 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3199 * ports.c (scm_add_to_port_table): First line is now line 0
3200 (was 1). (Interface changed according to suggestion by Per
3203 * backtrace.c (display_header): Add 1 to line and column numbers
3204 when presenting them to the user.
3206 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3207 from debug.c --> eval.c
3209 * eval.h, eval.c (scm_eval_options_interface): New options
3211 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3212 i.e. stacks for new threads.
3214 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3216 * eval.c (unsafe_setjmp): Removed with #if 0.
3218 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3221 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3222 to avoid compiler warnings.
3224 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3226 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3228 * throw.c (handler_message): Print message on current error port
3229 instead of default error port. (Thanks to Maciej Stachowiak.)
3231 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3233 * ports.c (scm_add_to_port_table): allocate in units of
3234 struct scm_port_table *, not struct scm_port_table.
3235 * posix.c (scm_close_pipe): remove the port from the port table
3237 Thanks to Rob Engle for both fixes.
3239 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3241 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3242 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3244 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3246 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3248 * backtrace.c (display_error_body, display_backtrace_body),
3249 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3250 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3251 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3252 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3255 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3256 don't receive the jmpbuf arg anylonger.
3257 (scm_catch): Don't accept a #f tag.
3258 (scm_throw): Check that key is a symbol.
3259 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3261 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3263 * async.c (async_pending): Removed declaration.
3265 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3267 * dynwind.c (scm_wind_chain): New debug function.
3269 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3270 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3271 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3272 extra layer of functions around the body and handler of a thread.
3273 This extra layer makes sure that the handler is called in the
3274 dynamic context of the surround (= empty dynwind list), but under
3275 the *dynamic root* of the body. We can not use the dynamic root
3276 of the surround since that root belongs to another thread => stack
3277 is not handled correctly. It may seem ugly to use this extra
3278 layer, but the extra cost in terms of execution time is really
3279 negligible compared to the total amount of time required to create
3280 a thread, and it would reduce maintainability to duplicate the
3281 crucial and complicated steps performed by cwdr.
3283 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3284 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3285 get re-enabled. The important effect of this is that interrupts
3286 are blocked during thread switching so that thread data structures
3287 don't risk getting messed up by an unfortunate signal.
3288 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3289 seems to do more aggressive optimization which actually move
3290 instructions around in these macros in a fatal way. Therefore:
3291 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3292 just superstitious...)
3293 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3294 This macro should be used instead of SCM_ASYNC_TICK since the
3295 latter doesn't do context switches any more.
3297 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3298 instead of SCM_ASYNC_TICK.
3300 * coop.c, iselect.c: Since thread switches are now performed with
3301 interrupts masked, we can't use the old mechanism of delivering
3302 signals immediately when they arrive. Signals must instead be
3303 delivered when the asyncs run *after* the end of the critical
3304 section in scm_internal_select. But this also means after context
3305 switch so that the signal will be delivered to a different thread.
3306 To avoid this, I have changed the protocol of
3307 coop_wait_for_runnable_thread and friends so that they are allowed
3308 to return the original thread. So, if a signal arrives during
3309 scm_internal_select, we won't any longer be forced do a context
3310 switch, but can remain in the same thread and deliver the signal
3313 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3314 scm_asyncs_pending and made it global.
3316 * iselect.c: Small fixes.
3318 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3319 coop_condition_variable_init, coop_condition_variable_wait,
3320 coop_condition_variable_signal): Changed return type from `void'
3321 to `int'. This is to adhere closer to the pthreads interface.
3322 This, in turn, is part of an attempt to provide C versions of the
3323 mutex and condition variable primitives which can be part of a
3324 frontend to COOP or pthreads.
3326 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3327 coop_condition_variable_destroy): New functions.
3329 * coop-threads.c (scm_wait_condition_variable): Use
3330 coop_condition_variable_wait_mutex.
3332 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3333 Definitions moved to coop-defs.h.
3335 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3336 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3337 scm_cond_destroy): New C interface to mutecis and cond vars.
3339 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3341 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3343 * iselect.c: Now several threads can wait on the same file
3344 descriptor. The behaviour is compatible with OS select: All
3345 threads waiting for the fd return with the same status.
3347 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3349 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3350 Can spawn a thread from application C code.
3352 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3354 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3355 gh_doubles2scm): New functions.
3357 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3359 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3360 commented-out version of gh_eval_str()
3362 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3364 * socket.c (scm_bind): free soka after use.
3366 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3368 * stime.c (tzvar): new variable.
3369 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3370 avoid memory leaks when allocating.
3372 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3374 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3377 * gc.c, tags.h: Doc fixes.
3379 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3381 * eval.c (macro-eval!): Removed. This function was a design bug.
3382 It allowed memoized code to leak out to the scheme level. Most
3383 things that you could do with `macro-eval!' can be done with
3386 1997-12-20 Tim Pierce <twp@skepsis.com>
3388 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3389 scm_fgets now depends on ftell(3) to know how many bytes were
3392 1997-12-15 Tim Pierce <twp@skepsis.com>
3394 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3395 dealing with strings.
3397 1997-12-13 Tim Pierce <twp@skepsis.com>
3399 Make %read-line more suitable for implementing read-line efficiently.
3400 * ioext.c (scm_read_line): Strip the terminating newline from a
3401 string, and return a cons of the string and its terminator.
3403 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3404 of the string that is read is stored in this memory location.
3405 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3406 * genio.c, genio.h (scm_do_read_line): Update caller.
3407 * ports.h (scm_ptobfuns): Update typedef.
3408 * fports.c (scm_fptob, scm_pipob): Update struct.
3410 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3412 * filesys.c (set_element): Return file descriptor.
3413 (fill_select_type): Return the highest file descriptor.
3414 (scm_select): Tell select about the highest file descriptor. On
3415 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3416 Therefore the extra overhead for calculating the maximum fd seems
3417 to be more than compensated. Is this correct? In any case,
3418 scm_internal_select will be much faster with this info.
3419 (scm_select, fill_select_type, set_element): Don't accept any kind
3420 of object in the file descriptor list or vector.
3422 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3424 * iselect.c (finalize_fd_sets): Bugfix.
3426 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3428 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3429 when using scm_internal_select (since we might switch to another
3432 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3434 * simpos.c (scm_system): always define: use sysmissing if not
3435 available. Check for HAVE_SYSTEM instead of _Windows (does
3436 Windows lack system or does it have an unusable one?).
3437 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3438 Let the argument be optional: if not supplied, call system(NULL).
3440 * ports.c (scm_close_port): relax the type check from OPPORTP to
3441 PORTP; closing a closed port is allowed.
3443 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3445 * fports.c (scm_fgets): Return if the last char in a chunk is
3446 newline. When fgets returns a string whose length is `size-1', it
3447 is ambiguous whether a whole line was retrieved, so we must check
3448 explicitly whether a line terminator is present.
3450 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3452 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3453 before taking the CDR. (Thanks to Harald Meland.)
3455 * filesys.c (scm_stat): Slightly optimized.
3457 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3459 * ports.c (scm_close_port): Make sure the port is open before
3462 * guile-snarf.in: Pass args through to gcc in a way that preserves
3463 whitespace boundaries. (Thanks to Greg Badros.)
3465 1997-12-02 Tim Pierce <twp@skepsis.com>
3467 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3468 statement. (Thanks to Doug Evans for pointing this out.)
3470 1997-12-01 Tim Pierce <twp@skepsis.com>
3472 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3474 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3476 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3477 errno macro expansion of this field name. (errno is a C
3478 preprocessor macro on some systems.)
3480 1997-11-29 Tim Pierce <twp@skepsis.com>
3482 * iselect.c: Doc fix.
3484 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3486 * init.c (scm_start_stack): Removed initialization of
3487 scm_the_last_stack_var.
3489 * backtrace.h: Declare scm_the_last_stack_var.
3491 * backtrace.c: Define scm_the_last_stack_var.
3493 * root.c (mark_root): Don't mark the_last_stack_var.
3495 * root.h (scm_root_state): Removed the_last_stack_var.
3497 * throw.c: Added #include "fluids.h"
3498 (ss_handler): `the-last-stack' is now a fluid.
3500 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3501 --> the_last_stack_fluid.
3503 * backtrace.c: Added #include "fluids.h"
3504 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3505 (scm_backtrace): `the-last-stack' is now a fluid.
3507 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3508 after scm_init_fluids.
3510 1997-11-28 Tim Pierce <twp@skepsis.com>
3512 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3514 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3515 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3517 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3519 * iselect.c (coop_next_runnable_thread,
3520 coop_wait_for_runnable_thread): Disable interrupts so that no
3521 async is executed before a potential error_revive.
3522 (scm_internal_select): Disable interrupts during the parts of the
3523 code which manipulate the sleep queue and the file descriptors.
3525 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3527 * Makefile.am: Added iselect.c and iselect.h.
3529 * coop.c (coop_qinit): Initialize fields used by
3530 scm_internal_select.
3531 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3532 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3533 replacement in iselect.c.
3534 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3535 coop_join): If GUILE_ISELECT enabled, use
3536 coop_wait_for_runnable_thread instead of
3537 coop_next_runnable_thread.
3538 (usleep, sleep): New replacements for system functions if
3539 GUILE_ISELECT is enabled.
3541 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3543 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3545 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3546 iselect.h. Implement Scheme level `select' using
3547 scm_internal_select. (See NEWS.)
3549 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3551 * init.c: Call scm_init_iselect.
3553 * iselect.h, iselect.c: New files. Implements
3554 scm_internal_select. (See NEWS.)
3556 1997-11-27 Tim Pierce <twp@skepsis.com>
3558 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3559 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3560 and scm_must_free, since ultimately the string returned will be copied
3561 by scm_makfrom0str anyway. Also, read any characters that may have
3562 been pushed onto the port with scm_ungetc.
3563 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3564 * ioext.c (scm_read_line): Free string after Guilifying it.
3565 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.

3575 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3576 gh_repl (argc, argv).
3578 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3580 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3581 and to invoke scm_shell().
3582 (gh_launch_pad): took out the loading of boot-9.scm from here,
3583 since it is probably best to let the user control that. In fact,
3584 gh_repl() now invokes scm_shell() which does that.
3586 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3588 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3591 1997-11-22 Tim Pierce <twp@twp.tezcat.com>

3605 (gh_uniform_vector_ref): started implementing the uniform types in
3608 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
3610 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3611 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3613 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3615 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
3616 configure.in was changed).
3618 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
3620 * Makefile.am (modinclude_HEADERS): Include readline.h here.
3621 * Makefile.in: Regenerated.
3623 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
3625 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
3626 OPORT is an `open' port, not an output port.
3628 * filesys.c (scm_close, set_element, get_element, scm_chown,
3629 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use

3633 scm_port_column, scm_set_port_column_x, scm_port_filename,
3634 scm_set_port_filename_x, scm_port_mode,
3635 scm_close_all_ports_except, scm_set_current_output_port,
3636 scm_set_current_error_port): Likewise
3637 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
3638 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
3640 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
3641 * backtrace.c (display_backtrace_body): Likewise
3642 * fports (scm_setvbuf): Likewise
3643 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

3648 Sat Oct 25 02:52:58 1997 Jim Blandy <jimb@totoro.red-bean.com>
3650 Minor problems with substring-related tag changes.
3651 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
3652 exactly what we want to leave in to detect substrings.
3653 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
3654 * tags.h: Fix diagrams and comments describing the S tag bit;
3655 remove vestigial remarks about the D tag bit.
3656 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
3657 * strings.c: Formatting tweaks.
3659 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
3660 variable first; then SCHEME_LOAD_PATH, with a warning message.
3661 (scm_parse_path): New function.
3662 * script.c: Doc fixes.
3664 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
3666 Readline support, from Daniel Risacher.
3667 * readline.c, readline.h: New files.
3668 * init.c: #include "readline.h".
3669 (scm_boot_guile_1): Call scm_init_readline, if we have it.
3670 * Makefile.am (libguile_la_SOURCES): Include readline.c.
3671 * Makefile.in: Regenerated.
3672 * scmconfig.h.in: Regenerated, after change to ../configure.
3674 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3676 * gh.h: gh_vector_set -> gh_vector_set_x
3678 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3680 * gh_data.c (gh_vector_set_x): changed name to make it consistent
3681 with the ! -> _x mapping when going from Scheme to C.
3683 1997-10-19 Mark Galassi <rosalia@cygnus.com>
3685 * gh.h (gh_reverse):
3693 (gh_assoc): added these gh_ functions implemented as macros.
3695 * gh_predicates.c (gh_null_p):
3696 (gh_string_equal_p): added these two missing predicates.
3698 * gh_list.c (gh_append):
3703 (gh_set_cdr_x): added these routines as I go through and try to
3704 complete the picture R4RS functions that should be mirrored in the
3707 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3709 * tags.h (scm_tc7_substring): Changed the comment and code to
3710 conform with the changes below. Folks! We have suddenly two new
3711 free tc7 codes!!! Jummy, jummy!
3713 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
3715 * Makefile.in: Rebuilt.

3736 (scm_tc7_mb_string): Removed.
3737 (scm_tc7_mb_substring): Removed.

3740 Don't include "mbstrings.h".
3741 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
3742 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
3744 Don't include "mbstrings.h".
3745 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
3746 (SCM_SYMBOL_SLOTS): Define as 4.

3748 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
3749 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
3750 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
3751 struct.c, threads.c, throw.c, unif.c, variable.c: Use new

3771 1997-10-12 Mark Galassi <rosalia@cygnus.com>
3773 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
3775 * gh_test_c.c (c_vector_test): some improvements on the vector
3778 * gh.h (gh_vector): this used to exist but do the wrong thing.
3779 Now it (almost) does the right thing, though it takes a list
3780 instead of the individual arguments. I need to see how it could
3782 (gh_list_to_vector): added this function as a macro. Corresponds
3783 to Scheme's (list->vector ...).
3784 (gh_vector_to_list): added this function as a macro. Corresponds
3785 to Scheme's (vector->list ...).
3787 * gh_data.c (gh_vector_ref): renamed from gh_vref to
3788 gh_vector_ref, so that it resembles the Scheme routines more.
3789 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
3790 resembles the Scheme routines more.
3791 (gh_make_vector): this used to be (stupidly) called gh_vector().
3792 This is the right name, since it does the same thing as the Scheme
3793 (make-vector ...) procedure.
3795 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
3797 * ports.h: #include "libguile/print.h"
3799 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
3800 Some indentation fixes.
3802 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
3803 longer a user field; New field: class_flags.
3805 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
3807 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
3809 * gh_data.c (gh_bool2scm): new function which replaces
3810 gh_int2scmb(), which is now tagged as obsolete.
3812 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
3814 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
3815 macros should by convention not test for NIMPness.)
3816 (SCM_COERCE_OPORT): Adjust indentation.
3818 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
3819 SCM_NIMP test before SCM_PRINT_STATE_P.
3821 * struct.c, struct.h, gc.c: Renamed:
3822 scm_struct_i_layout --> scm_vtable_index_layout
3823 scm_struct_i_vcell --> scm_vtable_index_vcell
3824 scm_struct_i_vtable --> scm_vtable_index_vtable
3825 scm_struct_i_printer --> scm_vtable_index_printer
3826 scm_struct_i_vtable_offset --> scm_vtable_offset_user
3828 * struct.c (scm_print_struct): Use new printer slot; Default
3829 printing: Also output hex code of vtable so that type identity
3830 will be indicated as well.
3831 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
3832 Removed struct_printer_var; Removed struct-vtable-offset;
3833 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
3834 vtable-offset-user): New constants.
3836 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
3837 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
3838 If this slot contains a procedure, use that to print structures of
3839 the type represented by this vtable.
3841 * print.c (scm_iprin1): Don't print arguments of macro
3842 transformers. (They are always: exp env.); Bugfix: Unmemoize
3843 transformer source with correct environment.
3845 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
3847 Streamlining of call-with-dynamic-root:
3849 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
3850 there is now only one catch.
3851 (cwdr_outer_body): Removed.
3852 (cwdr_handler): New function.
3853 (scm_internal_cwdr): New function to perform the function of cwdr
3854 but take args that are more useful to C code. Also, the handler
3855 is now invoked *outside* of the new dynamic root, like the docs
3856 say. We no longer have to catch absolutely all errors, the caller
3857 is responsible for using a handler that does not throw, if he
3859 (cwdr): Reimplemented in terms of scm_internal_cwdr.
3860 * root.h (scm_internal_cwdr): New prototype.
3862 Even more but risky streamlining:
3864 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
3865 allocation of the jumpbuf of a root continuation. The changes
3866 below are controlled by it. They are now deactivated.
3867 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
3868 the JMPBUF of the scm_rootcont to NULL before returning.
3870 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
3871 when they are non-NULL.
3872 (scm_gc_mark): Likewise, mark only when non-NULL.
3874 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
3875 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
3877 * gc.c (scm_done_malloc): New function.
3878 gc.h (scm_done_malloc): New prototype.
3880 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.

3887 a certain value is acceptable as a port argument.
3888 (scm_print_state_vtable): New variable.
3889 (scm_free_print_state): Set `revealed' field to false.
3890 (scm_iprin1): Call user supplied closure printer with
3891 scm_printer_apply. Print in the traditional way when there isn't
3892 one or when it returns #f.
3893 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
3894 Accept a port/print-state pair in addition to just a port.
3895 (scm_prin1): Don't return the print_state to the pool when it has
3897 (scm_printer_apply): Set `revealed' field of print_state to true.
3898 (scm_init_print): Set scm_print_state_vtable.
3899 (print_state_fluid, print_state_fluid_num): Removed.
3901 * throw.h (scm_handle_by_proc_catching_all): New prototype
3902 throw.c (scm_handle_by_proc_catching_all): New function
3904 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
3906 * Makefile.in: Regenerated with automake 1.2c.
3908 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
3910 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
3911 was looping endlessly.
3913 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
3915 * strports.c (scm_eval_string): Don't close the port.
3917 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
3918 former returns a nice normal integer. (Thanks to Daniel
3921 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
3923 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
3924 makefile variable as a build parameter called LIBS. The
3925 build-guile program will use this, for the time being.
3926 * Makefile.in: Regenerated.
3928 Thanks to Shiro Kawai:
3929 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
3930 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
3933 * Makefile.in: Regenerated with automake 1.2a.
3935 * script.c (scm_compile_shell_switches): If we hit the -c or --
3936 arguments, don't set the car of (command-line) to scm_usage_name,
3937 the prettified name of the guile executable; give it the full
3938 path, the way shells usually handle $0.
3940 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3942 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
3943 Scheme-level name `array-map' and renamed `serial-array-map' to
3944 `serial-array-map!'.
3946 * backtrace.c: Introduced exception handlers which now enclose
3947 `display-error' and `display-backtrace' so that error reporting
3948 won't get into infinite loops if an error occurs during displaying
3949 of the error. This can very easily happen with user supplied
3950 print call-back routines.
3952 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3954 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
3955 the names `serial-array-map' and `array-map' should be removed.)
3957 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
3959 * init.c (scm_boot_guile_1): Added scm_init_objects ().
3960 Added #include "objects.h"
3962 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
3963 Add #include "feature.h".
3965 * Makefile.am (libguile_la_SOURCES): Added objects.c.
3966 (modinclude_HEADERS): Added objects.h.
3968 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
3969 This test is needed at many places in the code and should be
3970 abstracted. (Motivated by the need of this test in libguiletk.)
3972 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
3973 (scm_eval_string), load.c (scm_primitive_load,
3974 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
3975 Use SCM_EOF_OBJECT_P.
3977 * eval.c (scm_init_eval): Add feature `delay'.
3979 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3981 * scmhob.h: Removed.
3983 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3985 * list.h (SCM_LISTn): New macros. Make list creation in C code
3986 prettier. The idea comes from STk.
3988 * sequences.h, sequences.c, append.h, append.c: Removed. These
3989 files implemented non-R4RS operations which would encourage
3990 non-portable programming style and less easy-to-read code.
3992 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
3995 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
3996 sequences.h, #include append.h.
3998 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
4001 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
4003 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
4005 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
4007 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4009 * eval.c: Added #include "objects.h"
4011 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
4014 * smob.c (scm_smob_prehistory): Create two objectsmobs with
4015 adjacent smob numbers.
4017 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4019 * procprop.h: Added declaration of scm_i_inner_name.
4021 * gsubr.c: New global symbol scm_i_inner_name.
4023 * debug.c (scm_procedure_name): Try procedure property
4024 `inner-name' if `name' fails.
4026 * print.c (scm_iprin1): Use scm_macro_name.
4028 * eval.c (scm_m_define): Give names to macros as well; Only the
4029 first top-level definition gives a procedure/macro a name.
4030 Otherwise confusing names can turn up in backtraces.
4031 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4032 `name'; Give names to macros as well.
4034 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4035 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4038 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4040 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4042 (prinmacro): Removed. The code has been moved/merged into print.c
4043 in order to decrease code redundancy. We want macros to print in
4044 a way equivalent to procedures, and it would be silly to duplicate
4045 the required code. (We don't want to maintain two places.)
4046 (macrosmob): Print field is now a NULL pointer.
4048 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4049 scm_macro_transformer): New prototypes.
4050 (scm_tc16_macro): Declared.
4052 * print.c (scm_iprin1): Added code for printing of macros. Macros
4053 are now printed in a way equivalent to procedures.
4055 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4057 * procs.h (scm_closure_p): Added declaration.
4059 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4061 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4062 Shouldn't pass "heap" as the subr name.
4064 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4066 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4067 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4068 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4069 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4070 SCM_BOOL_T. Any non-false value is true.
4072 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4074 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4075 scm_gensym): Added prototypes.
4077 * symbols.c (scm_gensym): New function. This will speed up
4078 certain types of applications (such as macro systems) which
4079 generate lots of symbols.
4081 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4083 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4085 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4087 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4088 specifier, since (2) or (2 . 3) would cause SEGV.
4089 (scm_transpose_array): more argument checking fixes.
4091 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4093 * Makefile.in: Regenerated.
4095 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4097 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4099 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4101 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4103 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4105 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4106 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4109 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4110 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4111 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
4112 scm_array_p, scm_array_rank, scm_array_dimensions,
4113 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
4114 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
4115 scm_array_prototype): Added case scm_tc7_wvect.
4117 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
4119 * errno.h: prototype for scm_strerror.
4120 * error.c (scm_strerror): new procedure.
4122 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4124 * list.c (scm_list_append_x): Allow non-pair as last argument.
4125 This is consistent with the R4RS append and is probably the
4126 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4128 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4130 * stime.h: prototype for scm_times.
4131 * stime.c (scm_times): new procedure.
4132 * ioext.c (scm_fseek): if the first argument is a file descriptor
4134 (scm_ftell): if the first argument is a file descriptor call lseek
4136 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
4137 * filesys.c (scm_chmod): if the first argument is a file descriptor,
4139 (scm_chown): if the first argument is a port or file descriptor,
4141 (scm_truncate_file): new procedure.
4142 Add DEFER/ALLOW INTS to a few other procedures.
4143 (scm_fsync): new procedure.
4144 (scm_open_fdes): new procedure.
4145 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
4147 (scm_fcntl): the first argument can now be a file descriptor. The
4148 third argument is now optional.
4150 * posix.c (scm_execl, scm_execlp): make the filename argument
4151 compulsory, since omitting it causes SEGV.
4152 (scm_sync): return unspecified instead of #f.
4153 (scm_execle): new procedure.
4154 (environ_list_to_c): new procedure.
4155 (scm_environ): use environ_list_to_c. disable interrupts.
4156 (scm_convert_exec_args): take pos and subr arguments and
4157 improve error checking.
4159 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4161 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4162 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4163 argument to SCM_ASSERT. Furthermore, the name of the function
4164 should be passed as first argument when signalling
4165 SCM_WNA. (Thanks to Thomas Morgan)
4167 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4168 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4169 dispatches on the number of actual args has a default case
4170 reporting an internal error. This is a vestige from a version
4171 that mallocated a SCM vector to hold the arguments. In the
4172 current version this check is too late: if it ever happens we will
4173 have already overstepped the bounds of the array.
4175 Also, the patch [...] adds a check for too many actual arguments."
4177 mdj: Removed check for "internal programming error".
4179 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4181 * gh_io.c (gh_write): New function.
4183 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
4184 throw.c (scm_internal_stack_catch): New sibling to the other catch
4185 functions. Code moved from gh_eval.c.
4186 throw.h: Added header.
4187 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
4188 scm_internal_stack_catch.
4190 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4192 * ioext.h: fix up prototypes.
4193 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
4194 Scheme name is now dup->fdes.
4195 (scm_dup_to_fdes): make the second argument optional and
4196 fold in the functionality of scm_primitive_dup.
4197 (scm_primitive_dup): deleted.
4199 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
4201 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
4202 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
4203 ultrix are defined. Use setvbuf instead of setbuf.
4204 (scm_setvbuf): new procedure.
4205 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
4206 (scm_setfileno): moved from ioext.c.

4218 state as nested data while they are printed.
4219 (print_state_fluid, print_state_fluid_num): New variables.
4220 (scm_init_print): Initialize them.
4221 (scm_iprin): If print_state_fluid carries a print_state, use that
4222 instead of creating a new one.
4223 (scm_printer_apply, apply_stub, struct apply_data): New
4224 definitions to help with calling printer functions written in
4226 * print.h (scm_printer_apply): New prototype.

4239 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
4240 SCM_ASSERT: arg comes before pos.
4242 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4244 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
4245 to a list of length zero correctly.
4247 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

4263 * ioext.h: removed scm_duplicate_port prototype.
4265 * ioext.c (scm_primitive_dup2): return the new file descriptor
4266 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
4268 (scm_fdopen): bug fix: don't try to make port unbuffered until its
4269 stream has been set.
4270 (scm_duplicate_port): deleted, there's now an implementation in
4272 (scm_primitive_dup2): do nothing if newfd == oldfd.
4274 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
4276 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

4282 * fluids.c (next_fluid_num): don't do
4283 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
4285 * ports.h: prototypes too.
4286 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
4288 * fports.h: prototype too.
4289 * fports.c (scm_evict_ports): moved from ioext.c.
4291 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
4293 * ports.c (scm_close_port): return a boolean instead of unspecified.
4294 throw an error if an error other than EBADF occurs.
4296 * filesys.h: scm_close prototype.
4297 * filesys.c (scm_close): new procedure, can close file descriptors
4298 and ports (scsh compatible).
4300 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
4303 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
4305 * fluids.c, fluid.h: New files.
4306 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
4307 (modinclude_HEADERS): Added "fluids.h"

4316 (scm_make_root): Call scm_copy_fluids to make fluid bindings
4317 unique for the new root when it has a parent.
4319 * smob.h: Include "libguile/print.h" to make scm_print_state
4322 * dynl.c (free_dynl_obj): New function to free the dynamic object
4323 data. (dynl_smob): Use it.
4324 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4325 the dynamic object data below the linking of the object to avoid
4326 memory leak when the linking code throws an error. Now the code
4327 leaks a whole dynamically linked library when must_malloc throws,
4328 but that should be much less likely.
4330 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4332 Changes to compile under gnu-win32, from Marcus Daniels:

4334 (scm_localtime): Change SCM_EOF to SCM_EOL.
4335 (scm_mktime): Likewise.

4339 (scm_addr_vector): Likewise.
4340 (scm_init_addr_buffer): Likewise.

4348 (scm_setpwent): For setpwent.
4349 (scm_setegid): For setegid.
4350 * net_db.c (scm_inet_netof): Don't include unless support

4366 scm_misc_error, not SCM_EOF.
4368 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of

4370 think this is left over from the (eq? '() #f) days.
4372 * read.c (recsexpr): Give this a dummy definition if
4373 DEBUG_EXTENSIONS isn't #defined.
4375 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
4377 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

4387 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
4388 alloca.lo will be included in @LIBLOBJS@. Something better than
4389 this should be possible.
4390 * Makefile.in: Regenerated.
4392 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4394 * simpos.h: prototype for scm_primitive_exit.
4395 * simpos.c (scm_primitive_exit): new procedure, terminates the
4396 process without unwinding the stack.
4398 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
4400 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
4401 argument and logior its components together, so the user doesn't
4402 have to do this explicitly. Also, if regexp/basic is supplied, then
4403 turn off REG_EXTENDED.
4404 (scm_init_regex_posix): New regexp/basic symbol.
4405 (REG_BASIC): #define this if it is not already present.
4407 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

4421 * Makefile.in: Regenerated.
4423 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
4424 flag; I don't think we support it.
4425 (scm_make_regexp): Make sure the user doesn't pass the
4428 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
4430 (scm_init_regex_posix): Define constants for the REG_mumble flags;

4438 Makefile directory variables. Print a message, but don't print
4440 (versiondat.h): Print a message, but don't print all the commands.
4441 * load.c: #include "alist.h".
4442 (init_build_info): New function.
4443 (scm_init_load): Call it.
4444 * Makefile.in: Regenerated.
4446 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
4448 * root.c: Establish a reliable catch-all handler for the new root.
4449 After all the Scheme handler function might signal an error too,
4450 and we don't want to lose that.
4451 (cwdr_inner_body): Renamed from cwdr_body.
4452 (cwdr_outer_body): New function, to establish the user's handler,
4453 and pass control to cwdr_inner_body.
4454 (cwdr): Establish the reliable catch-all handler here, and pass
4455 control to cwdr_outer_body.
4456 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
4457 the user's handler through to cwdr_outer_body.

4464 across this. Only works on GCC. Otherwise, we hope for the best.
4465 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4466 the feeling that real thread systems will not need this...
4468 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4470 Try to detect when people are using one version of libguile and a
4471 different version of ice-9. People have been skewing things and
4472 sending in bug reports.
4473 * Makefile.am (versiondat.h): New file to generate.
4474 * version.c: #include "versiondat.h", to get version info.
4475 (scm_libguile_config_stamp): New function.
4476 * script.c: #include "version.h".
4477 (scm_compile_switches): Call scm_version to get version number.
4478 * scmconfig.h.in, Makefile.in: Regenerated.
4479 * Makefile.in: Regenerated.
4481 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
4482 primitive definitions under their Scheme names.
4484 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4485 1:2. Helps avoid confusion between installed and uninstalled libs.
4487 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
4490 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
4491 backslash from definition; this should be used like: GDB_INTERFACE;
4493 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4495 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
4496 new port unbuffered until its stream has been set.
4498 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
4500 * ports.h: new prototype.
4501 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
4503 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
4505 Make things compile neatly under Sun's C compiler.
4506 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
4507 * extchrs.c (xmbtowc): Make the second arg a normal char, not
4508 unsigned, because that's what the ANSI function takes.
4509 * extchrs.h (xmbtowc): Corresponding change to prototype.
4510 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4512 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
4513 argument plain char *.
4514 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
4516 * tag.c (scm_tag): Remove unreachable statement.
4517 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4518 top of the word, it should be unsigned.
4520 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4521 is defined, to avoid warnings; it's only used in the
4522 conflict-checking code. Which might go away anyway.
4523 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4524 conditionals; put the label definition in an #if too, to stifle
4527 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4528 ChangeLog-threads in the distribution.
4529 * Makefile.in: Regenerated.
4531 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4533 * guile-snarf.in: Changed regexp to support CPPs that insert
4534 whitespace between lexical tokens (which munges the `%%%' snarf
4537 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4539 * load.c (scm_init_load_path): Append $(datadir)/guile to
4540 %load-path, so modules do not have to be installed in Guile's
4541 current version directory.
4543 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
4545 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
4546 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
4547 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
4548 call the sysdep functions with deferred ints.
4549 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
4550 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
4551 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
4554 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
4557 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
4559 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
4561 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
4563 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
4566 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
4568 * eval.c (scm_lookupcar1): New procedure to cope with a race
4569 condition during lookup (when using threads).
4570 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4571 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4574 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4576 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4577 supplied. (Change from Tim Pierce.)
4579 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4581 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4582 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4583 default and not `()'. `#f' is the canonical non-value in Scheme,
4586 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4588 * struct.c (struct_printer): New variable that holds a handle on
4589 the Scheme variable *struct-printer*. This variable can be set by
4590 Scheme code to override the printing of structures.
4591 (scm_print_struct): If struct_printer is set, call it. If it is
4592 not set, or returns #f, print the structure in the old fashion.
4593 Include "eval.h" for scm_apply.
4595 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4597 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4598 scm_struct_i_n_words to get the number of fields, not
4599 -scm_struct_n_extra_words.
4601 On the route to fancier struct printing:
4602 * struct.c (scm_print_struct): New function to print a structure.
4603 Include "genio.h" to support it. This function doesn't do
4604 anything interesting right now, but I think it should be here
4606 * struct.h: Include "print.h" and add prototype for
4608 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4609 print structures ourself.
4611 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4613 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
4614 before applying the handler in case it doesn't return.
4616 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
4618 * scmsigs.h, async.h: updated.
4620 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
4623 * posix.c (scm_uname): interpret only negative values as an error.
4624 Solaris normally returns a positive value.
4626 * script.c (scm_compile_shell_switches): if we are not going into
4627 an interactive repl, set scm_mask_ints to zero so that asyncs can
4630 * simpos.c (scm_system): don't ignore/unignore signals around
4633 * posix.c (scm_open_pipe): don't ignore/unignore signals around
4636 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
4637 done in boot-9.scm instead.
4639 * scmsigs.c, async.c: Major rewriting of signal handling code.
4640 (scm_sigaction): new procedure.
4641 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
4643 (scm_raise): return unspecified, throw error on failure.
4645 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4647 * regex-posix.c (scm_init_regex_posix): Register the "regex"
4648 feature, to help boot-9.scm decide whether to import the regex
4651 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
4653 * eval.c: Include scmconfig.h at the beginning of the file so that
4654 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
4657 * regex-posix.c: #include "_scm.h" before conditionally #including
4658 <regex.h>; the former defines HAVE_REGCOMP.
4660 * regex-posix.c: #include <regex.h> conditionally, so the file is
4661 CPP'able (for dependency scanning) even on systems that don't have
4664 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4666 Add new R4RS-compliant syntax for keywords.
4667 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
4668 regardless of the setting of the `keywords' read option.
4669 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
4670 can be re-read no matter what the setting of the `keywords' read
4673 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
4675 Add support for POSIX regular expressions.
4677 * regex-posix.c, regex-posix.h: New files. (Some code
4678 is taken liberally from rx/rgx.c in the old Guile dist.)
4680 * init.c: Include regex-posix.h.
4681 (scm_boot_guile_1): Call scm_init_regex_posix.
4683 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
4684 Add regex-posix.[ch] sources.
4685 * Makefile.in: Regenerated.
4687 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
4688 to do this automatically? It didn't for me, bleh.)
4690 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
4692 * fports.c (print_pipe_port): New function.
4693 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
4694 latter doesn't even take the right arguments.
4696 * Makefile.am: Increment shared lib revision number. I think
4697 sometimes the uninstalled Guile finds the installed shared lib;
4698 Gord says doing this might help. As things turned out, I can't
4699 say whether it does.
4700 * Makefile.in: Regenerated.
4702 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
4703 passing it as the closure argument to scm_boot_guile. (Bill
4706 * ports.c (print_void_port, putc_void_port, puts_void_port,
4707 write_void_port, flush_void_port, getc_void_port, close_void_port,
4708 noop0): Use ANSI prototypes instead of K&R declarations, so the
4709 initialization of void_port_ptob gets aggressively type-checked.
4710 Fix arguments of print_void_port and write_void_port. (Bill

4744 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
4746 * script.c (scm_find_executable): Use prototype-style definition
4747 here; apparently it's not quite right to have const in a prototype
4748 and then use a K&R declaration. I wonder if stuff like this will
4749 go away if we compile with -Wrequire-prototypes, or whatever that
4750 is... (Bernard URBAN)
4752 * scmhob.h: New text from Bernard URBAN.
4754 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4756 * script.c: Don't #define const on hpux. Configure takes care of
4757 this. (Thanks to Larry Schwimmer.)
4759 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
4760 decide whether to #include <unistd.h>, instead of listing a bunch
4761 of systems. Don't #include stdio twice. Removed dyked-out
4762 definition of scm_find_impl_file.
4764 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4766 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
4767 library version info to 1:0.

4774 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
4775 throw.c: Update copyright years; these files have been worked on
4776 significantly in 1997, but only had copyright years for 1996.
4777 Also, change name of copyright holder on some from Mikael
4778 Djurfeldt to Free Software Foundation; he has signed papers
4779 assigning the changes to the FSF.
4781 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
4782 reason not to give the user the option.
4784 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
4785 Return #f on end-of-file when scanning table (i.e. when called
4786 with no arguments). Try to catch errors, when we can.
4787 * posix.c (scm_getgrgid, scm_getpwuid): Same.
4789 * script.h (scm_shell_usage, scm_compile_shell_switches): New
4790 external declarations. These are useful.
4792 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
4794 * posix.c: don't include <sys/select.h> or define macros for
4795 select, since they were not used in this file.
4797 * filesys.c (scm_select): make the fifth parameter microseconds,
4798 not milliseconds. let the fourth parameter be either a real value
4799 or an integer or #f. The first, second and third arguments can
4800 now be vectors: the type of the corresponding return set will be
4802 (set_element, get_element): new static procedures.
4804 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
4806 * strports.c (scm_eval_string): New function.
4807 (scm_eval_0str): Trivially re-implemented in terms of
4809 * strports.h (scm_eval_string): New extern decl.
4811 * net_db.c (h_errno): Add extern decl for this.
4813 * fports.c (local_pclose): New function.
4814 (scm_pipob): Use it in the initializer here.
4817 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
4818 Use a meaningful error message when signalling an error. For
4819 this, scm_gethost must check h_errno rather than errno.
4821 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
4823 * Makefile.in: Regenerated, using automake-1.1p.
4825 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
4827 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
4828 not SCM_UNSPECIFIED.
4830 * script.c (scm_compile_shell_switches): don't append (quit) if
4832 (scm_shell): call scm_exit_status and exit on the result of the
4835 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
4837 Ensure that shared substrings are handled properly when passed to
4838 a system call or other foreign function. Many thanks to Tim
4840 * symbols.h (SCM_COERCE_SUBSTR): new macro.
4841 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
4842 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
4843 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

4858 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
4860 * error.c (scm_error): Add newline to error message.
4862 * init.c (scm_init_standard_ports): Doc fix.
4864 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4866 * dynl-shl.c: Completely replaced with new code from Bernard
4869 * script.c (scm_ice_9_already_loaded): New variable.
4870 (scm_compile_shell_switches): Use it.
4872 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4874 * filesys.c (scm_input_waiting_p): add missing third argument to

4878 calling gmtime in case they share a buffer.
4879 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
4882 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
4884 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
4886 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
4888 * Makefile.am (check-local): New target, which causes 'make check'
4889 to run gh_test_c and gh_test_repl, with some trivial input.
4890 * Makefile.in: Rgnrtd.
4892 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
4894 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
4897 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
4899 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
4900 sure how this was supposed to work.
4901 (scm_async_click): don't send SCM_TICK_SIGNAL.
4902 (scm_init_async): don't initialize %tick-thunk.
4904 * the following change doesn't affect the Scheme interface:
4905 gc-thunk is called at the end of garbage collection. however it's
4906 no longer implemented by pretending it's a signal.
4908 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
4909 system async corresponding to scm_gc_thunk.
4910 * async.h: declare scm_gc_async.
4911 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
4912 gc-thunk directly, instead of going through a signal handler.
4913 (scm_gc_async): new variable, points to the GC system-async.
4914 (scm_init_async): save the GC async as scm_gc_async instead
4915 of using system_signal_asyncs.
4916 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
4918 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>

4921 Don't screw up if we're interrupted.
4922 * Makefile.in: Regeneradet.

4926 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
4928 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
4929 we're not using AM_INIT_GUILE_MODULE any more.
4930 * Makefile.in: Reneregated.
4932 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4934 Functions for finding variable bindings, grace à Tim Pierce.
4935 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
4936 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
4938 Get 'make dist' to work again.
4939 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
4940 * Makefile.in: Regenerated, like a surry without a fringe on top.
4942 Changes for reduced Guile distribution: one configure script,
4944 * configure.in, configure: Removed.
4945 * acconfig.h, acinclude.m4: Moved to parent directory, where the
4946 real configure script lives.
4947 * Makefile.in, scmconfig.h.in: Regenerated.
4949 * init.c: #include "script.h", to get prototype for script.c's
4952 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
4954 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
4955 scm_must_malloc, not raw malloc.
4957 * script.c (scm_compile_shell_switches): Dyke out debugging output
4960 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4962 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
4964 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
4965 system has them. Hope this is safe. Previously
4966 sys/timeb.h was included if HAVE_FTIME was defined or if
4967 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
4968 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
4970 * ioext.c (scm_setfileno): add missing third argument to
4971 scm_misc_error call.
4973 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
4975 * eq.c (scm_equal_p): Correctly compare strings of different
4976 varieties. (Thanks to Tim Pierce.)
4978 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
4980 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
4981 #! block comment must occur on a line all by itself.
4983 Move most of the guts of shell command processing into libguile,
4984 so guile.c can be very small (and eventuallly auto-generated. (I
4985 mean, generated mechanically, not self-generated. Hmm.))
4986 * guile.c, script.c, script.h: New source files.
4987 * init.c (scm_boot_guile_1): Call scm_init_script.
4988 * libguile.h: #include "script.h".
4989 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
4990 targets, for new executable.
4991 (libguile_la_SOURCES): Mention script.c.
4992 (modinclude_HEADERS): Add script.h.
4993 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
4994 not dynamic linking is enabled. This is because we're generating
4995 executables now. Move CY_AC_WITH_THREADS call after those, so the
4996 values of cy_cv_threads_libs captures the libs chosen above.
4997 * Makefile.in, configure, aclocal.m4: Regenerated.
4999 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
5000 We don't maintain this interface any more, and it just confuses
5003 * alloca.c: #include <scmconfig.h>, not <config.h>.
5004 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
5005 it'll get included in disties.
5007 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5009 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
5010 be distributed, because they confuse people.
5011 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
5013 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
5015 * configure.in: check for presence of gethostent (not present on
5016 OpenBSD by default).
5017 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
5018 * configure, scmconfig.h.in: Regenerated.
5020 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5022 * backtrace.c (scm_backtrace): Split message string across
5023 newlines properly. GCC is more tolerant of this than other
5026 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
5028 Merge threads directory into libguile.
5029 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5030 threads.h: New source files.
5031 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
5032 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
5034 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5035 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5036 coop-threads.c.cygnus, coop-threads.h.cygnus.
5037 * configure.in: If we're using threads, include threads.o in
5039 * _scm.h, libguile.h: threads.h lives in this directory now.
5040 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5041 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5042 currently used, but brought along for information's sake.
5043 * ChangeLog-threads: log from old 'threads' directory.
5044 * Makefile.in, configure: Rebuilt.
5046 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5048 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5051 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5053 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5055 Merge GH interface library into libguile.
5056 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
5057 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5058 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5059 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5061 (EXTRA_libguile_la_SOURCES): ... here.
5062 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5063 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5064 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5065 New variables, describing how to build the gh test programs.
5066 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5067 build the test programs, and we probably should have been linking
5068 libguile.la against them all along, to support AIX shared libs.
5069 Add cflags for threads to CFLAGS; add libs for threads to new
5070 variable THREAD_LIBS, used in Makefile.am.
5071 * ChangeLog-gh: log from old `gh' subdirectory.
5072 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5074 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5076 * acconfig.h: Undo change of Apr 9; including the definition of
5077 PACKAGE in the guile headers conflicts with applications' own
5079 * scmconfig.h.in: Regenerated.
5081 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

5088 when PROC is receiving no arguments.
5090 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5092 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5093 have S_IFSOCK. This is the case under Ultrix.
5095 * posix.c (scm_status_exit_val, scm_status_exit_val,
5096 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5097 Ultrix versions of WIFSTOPPED, etc., which assume that their
5098 arguments are lvalues (hmm).
5100 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5102 * eval.c: Doc fixes.
5104 * throw.c: Doc fixes; rearranged.
5106 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
5108 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
5110 * acconfig.h: Added entry for PACKAGE.
5111 * scmconfig.h.in: Regenerated.
5113 Changes to work with automake-1.1n, which has better libtool support.
5114 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5115 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5117 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5119 * Makefile.in: Rebuild.
5121 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5123 * stime.c (scm_mktime): take an optional zone argument.
5124 (scm_localtime): check putenv return value.
5125 (scm_strftime, scm_strptime): moved from posix.c. move #include
5127 stime.h, posix.h: update prototypes.
5128 (bdtime2c, setzone, restorezone): new static procedures.
5129 (scm_mktime, scm_strftime): use them.
5130 (scm_strftime): don't call mktime before strftime. Use
5131 filltime for return value.
5132 (filltime): convert NULL zname to #f.
5133 (scm_strptime): return a count of characters consumed, not
5134 the remaining string.
5136 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5138 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
5139 (scm_mktime): likewise.
5141 Uncomment localtime and mktime.
5143 * configure.in: add AC_STRUCT_TIMEZONE.
5145 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5147 * stime.c (scm_init_stime): don't define ticks/sec.
5148 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5149 return value problem and is still portable.)
5151 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5153 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5154 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5155 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5156 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5157 cpp_err_symbols.c): Corresponding changes.
5158 * Makefile.in: Regenerated.
5160 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5162 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5163 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5164 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5165 * putenv.c: new file, from sh-utils 1.12.
5167 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5168 since allocation isn't for Scheme objects.
5169 (scm_putenv): copy strings before placing in the environment.
5171 * stime.c (scm_current_time): throw an error if time returns -1,
5172 instead of returning #f.
5173 (scm_get_internal_real_time, scm_get_internal_real_time): use
5174 scm_long2num for return value instead of SCM_MAKINUM.
5176 * stime.h: prototypes updated.
5178 * stime.c (scm_time_in_msec): apparently unused, deleted.
5180 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5182 * configure.in: check for gettimeofday.
5184 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5185 which may be more usefully portable than a gettimeofday interface.
5187 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5189 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5191 * Makefile.in: Regenerated.
5193 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5195 * stime.c (filltime): recovered static procedure.
5196 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5199 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5200 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5202 * posix.c (scm_mknod): split the mode argument into type and perms
5203 arguments, like the extra fields returned by stat.
5205 * fports.c (scm_pipob): set the close, free and print procedures.
5206 (scm_close_pipe): new procedure.
5208 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5209 define them in boot-9.scm
5211 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5213 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5214 wan't defined. Don't include fd.h.
5216 * Previously fd.h was regenerated whenever configure was run,
5217 forcing a couple of files to be recompiled.
5219 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5220 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5221 Check for _fileno as well as _file.
5223 * ioext.c: don't fd.h.
5224 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5227 * Change the stratigy for getting information about errno
5228 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5229 generating lists of symbols during the build process, which will
5230 not always work, include comprehensive lists in the distribution.
5231 To help keep the lists up to date, the "check_signals" and
5232 "check_errnos" make targets can be used.
5234 * configure.in: don't check for a command to extract errno codes.
5235 * Makefile.am: update file lists, remove errnos.list and errnos.c
5236 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5237 check_errnos targets.
5238 (CLEANFILES): remove errnos.c and errnos.list, add
5239 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5240 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5241 * errnos.default: deleted.
5242 * cpp_signal.c: new file.
5243 * cpp_errno.c: renamed from errnos_get.c.
5244 * cpp_err_symbols, cpp_sig_symbols: new files.
5245 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5246 * error.c (scm_init_error): #include cpp_err_symbols instead of
5248 * posix.c (scm_init_posix): don't intern signal symbols. #include
5251 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5253 * strop.c (scm_i_index): allow the lower bound to be equal to the
5254 length of the string, so a null string doesn't always give an error.
5256 * posix.h: new prototypes.
5257 * posix.c (scm_status_exit_val, scm_status_term_sig,
5258 scm_status_stop_sig): new functions, as in scsh. They break down
5259 process status values as returned by waitpid.
5261 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5263 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5264 configure doesn't know about it.
5266 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5268 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5270 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5271 which defines C variables with global linkage.
5273 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5275 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5278 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5280 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5281 has time to check why this doesn't work well with continuations.
5283 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5285 * Fix shell syntax error; some shells won't tolerate
5286 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5288 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5290 * posix.c (scm_uname): throw an error if uname fails instead
5293 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5295 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
5298 * async.c (scm_ints_disabled): definition moved from error.c.
5300 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5302 * acconfig.h: Removed PACKAGE.
5304 * scmconfig.h.in: Regenerated.
5306 * snarf.h: g++ says it's non-portable not to specify the first
5307 argument in a varargs declaration. I introduced the first
5308 argument by using preprocessor conditionals.
5310 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5312 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5313 (scm_freopen): use RO string macros for filename and modes.
5314 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
5316 * posix.c (scm_getgrgid): simplify conversion of name to C string.
5317 (scm_mknod): use RO string macros for path.
5319 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
5320 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5322 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5323 use SCM_ROSTRINGP and SCM_ROCHARS.

5327 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5330 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5331 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5332 support for byte vectors.
5334 * print.c (scm_iprin1): Limit number of vector elements printed
5335 according to pstate->length.
5337 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>

5342 * error.h: prototype for scm_error_scm.
5344 * error.c (scm_error_scm): new procedure, reimplements scm-error
5345 in C and uses scm_error.
5347 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5349 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5350 pointer to the Scheme variable read-hash-procedures and intern it
5351 in scm_init_read. Modify scm_read_hash_extend and
5352 scm_get_hash_procedure to use the pointer.
5354 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5356 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5357 (SCM_KEYWORD_STYLE): defined.
5359 * read.c (scm_read_opts): add a keywords option. This isn't a
5360 boolean option, in case someone wants to add support for DSSSL
5362 Setup scm_keyword_prefix symbol.
5363 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5365 I've left keyword support disabled by default, since it doesn't
5366 seem to break the module system and it gives R4RS standard behaviour.
5367 It can be reactivated with (read-set! keywords 'prefix).
5369 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5371 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5372 before constructing arbiter.
5374 * eval.c (scm_m_define): Bugfix: Check that the object is a
5375 closure before setting the procedure property!
5377 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5379 * ports.c: Removed `ungetc-char-ready?'.
5381 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5383 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5384 (idea from Mikael: make it a pair so scm_permanent object only
5386 (scm_read_hash_extend): don't call scm_permanent_object.
5387 (ideas from Mikael): if chr is already in the list, replace its
5388 procedure instead of appending it again. If proc is #f, remove
5390 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5392 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5394 * gdbint.c (gdb_read): update scm_lreadr usage.

5407 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5408 for extended # processing.
5409 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5410 scm_read_token): remove case_i, sharp arguments. Change callers.
5412 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5414 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5415 (SCM_CASE_INSENSITIVE_P): define.
5417 * read.c: add case-insensitive option to scm_read_opts.
5418 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5419 to determine whether to convert symbol case.
5420 (default_case_i): definition removed.
5421 * read.c (scm_read_token): if case_i, downcase ic before doing
5424 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5426 * configure.in: Added configuration option `guile-debug'.
5427 Configure with --enable-guile-debug if you want a bunch of extra
5428 functions used for debugging when developing Guile.
5430 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5432 * procs.c (make-cclo): New undocumented debugging procedure: Make
5433 compiled closure with internal procedure PROC and length LENGTH.
5434 Only compiled if GUILE_DEBUG is defined.
5436 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5438 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5440 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5442 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5443 with 3 or more args internally to the evaluator.
5445 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5447 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5448 with 3 or more args internally to the evaluator. This is mainly
5449 because we don't want to pass entry and exit points of the
5450 debug support twice, but it also seems to increase the speed of
5451 the evaluator for such calls (e. g. (+ 1 2 3)).
5453 * backtrace.c (scm_display_application): New procedure:
5454 display-application; Set fancy printing parameters individually
5455 for different types of display (backtrace, error, application).
5456 (These should of course be customizable!)
5458 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5459 clear the CHECK-flags.
5461 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5463 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5465 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5467 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5468 from pairs with a GLOC in the car.
5470 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5471 otherwise `symbol-hash' will behave badly.
5472 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5473 we get segmentation fault!
5475 * symbols.c: Added #include "weaks.h". New functions:
5476 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5477 moved to an extraneous library when we split libguile.)
5479 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5481 * filesys.c (scm_stat): stat now takes fport arguments too as
5482 documented in the manual.
5484 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5486 * debug.c (scm_single_step): Bugfix: Call continuation with
5487 scm_call_continuation instead of throwing to it.
5489 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5491 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5492 argument wasn't declared to be optional.
5494 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5496 * stime.c (scm_init_stime): Add feature "current-time".
5498 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5500 * throw.h: prototype for scm_exit_status.
5501 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5502 args to derive an exit status. Allows (quit) to work from a
5504 (scm_exit_status): new function.
5507 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5509 * eval.c (scm_deval): Removed some old code.
5510 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5512 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5515 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5518 * procs.c: Introduce the existent C function scm_thunk_p at the
5519 Scheme level as well.
5521 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5523 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5524 used from C to easily lookup the value of a symbol in the current
5527 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5529 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5530 scm_init_unif in this file. This will also fix a previous problem
5533 * configure.in: Added AM_MAINTAINER_MODE
5535 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5537 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5540 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5542 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5543 source files that are not always included in libguile but should
5544 have their dependencies calculated by automake. This variable is
5545 recognized by automake, no further magic is needed.
5546 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5547 to deal exclusively with *.lo files, as it seems. The *.o files
5548 are built automatically when the corresponding *.lo file gets
5551 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5553 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5556 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5558 * unif.c (scm_array_set_x): minor change to argument error checking.
5560 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5562 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5563 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5564 They should only be included in the library at configure.in's
5566 (libguile_la_LDADD): Include the appropriate .lo files here.
5567 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5568 so we know when to build them (and their .lo bretheren).
5569 * configure.in (LIBLOBJS): New substituted variable. We let
5570 configure decide which .o files to include in LIBOBJS, and then
5571 put the corresponding list of .lo files in LIBLOBJS. The latter
5572 is what we pass to libtool.
5573 * Makefile.in, configure: regenerated.
5575 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5577 * symbols.c (scm_sysintern0): New function. Contains the core of
5578 old scm_sysintern but doesn't take a second value argument.
5579 (scm_sysintern): Now uses scm_sysintern0.
5580 (scm_sysintern_no_module_lookup): Renamed to
5581 scm_sysintern0_no_module_lookup and doesn't take a second value
5582 argument any longer.
5584 * symbols.h (scm_sysintern0: Added declaration.
5586 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5587 scm_sysintern when interning option keys. Otherwise we risk
5588 destroying the values of already interned variables.
5590 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5591 scheme-level boolean (use SCM_NFALSEP).
5593 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5595 (scm_backtrace): New function. (C version of old function from
5596 boot-9.scm) Motivation: Make it possible to display backtraces
5597 without depending on boot-9.scm. (I'm uncertain if this
5598 motivation is good enough...)
5600 * root.h (scm_root_state): Add member the_last_stack_var.
5601 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5603 * root.c (mark_root): Mark scm_the_last_stack_var.
5605 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5608 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5610 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5611 1. mark_lazy_catch didn't mark the smob.
5612 2. Both functions above have standard variants:
5613 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5614 free_lazy_catch --> scm_free0.
5616 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5618 * throw.c (scm_internal_lazy_catch): New function.
5619 (scm_lazy_catch): Rewritten to use it.
5620 (scm_ithrow): Handle the new lazy catch representation.
5621 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
5622 that doesn't have a jmpbuf is a lazy catch clause.
5623 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
5624 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
5625 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
5627 (scm_init_throw): Register the new lazy-catch smob type.
5628 * throw.h (scm_internal_lazy_catch): decl for new function.
5630 * throw.c (scm_internal_catch): Doc fixes.
5632 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
5633 configure.in. Including this might cause problems if applications
5634 that link against libguile include their own copies of alloca, but
5635 if they're using autoconf, they should be adding libguile to LIBS
5636 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
5637 the copy in libguile, and things will be okay. (I think.)
5639 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5641 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
5643 strop.h: move prototypes too.
5645 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5647 * posix.c (scm_init_posix): don't intern EINTR since it's now done
5650 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
5651 etc. I deleted them from filesys.c long ago, but didn't
5652 notice they were here too (although ineffective since
5653 sys/stat.h wasn't included).
5655 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
5657 * eval.c: Don't define alloca in GCC case. gcc will automatically
5658 use __builtin_alloca if appropriate.
5660 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5662 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
5663 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
5664 that values of automatic variables are preserved. See comments
5665 for safe_setjmp for details.
5667 Change from Thomas Morgan:
5668 * variable.c: Include eq.h.
5669 (var_equal): New function.
5670 (variable_smob): Use var_equal as the discriminator for variables.
5672 * throw.c (s_throw): Remove extraneous declaration.
5674 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
5675 * eval.c: Add necessary CPP cruft to support that.
5676 * configure, Makefile.in, scmconfig.h.in: regenerated.
5678 Change from Thomas Morgan:
5679 * procprop.c (scm_procedure_properties): Convert the Scheme
5680 boolean returned by scm_procedure_p into a C boolean before using
5681 it as a condition for SCM_ASSERT.
5682 (scm_procedure_property): Likewise.
5684 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
5685 indications of Unixness.
5688 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5690 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
5692 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5694 * read.c (scm_lreadr): use scm_misc_error to improve one of the
5695 "unknown # object" error messages.
5697 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
5698 (scm_i_index) and declare it static. Add a 'direction' argument
5699 to indicate what way the search should go.
5700 (scm_i_index): throw out-of-range error instead of wrong-type-arg
5702 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
5703 strop.h: remove scm_i_index, scm_i_rindex prototypes.
5705 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5707 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
5709 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
5710 to avoid clash with various scsh forks.
5712 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
5714 The following two changes (ramap.c, throw.c) are motivated by the
5715 apparent unportability of forward declarations of static arrays of
5716 the form `static foo bar[];'.
5718 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
5719 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
5721 * throw.c (scm_throw): Moved above scm_ithrow.
5723 * options.h: Removed the extern declarations of scm_yes_sym and
5724 scm_no_sym since these are static.
5726 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5728 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
5730 * Makefile.am: remove AWK=@AWK@.
5731 Add a rule for generating errnos.list.
5732 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
5734 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
5735 don't extract errnos, just set a variable (avoids the
5736 need to recompile error.c just because configure is run.)
5738 * unif.h: update prototypes.
5739 * unif.c (scm_uniform_array_read,write): change the offset and
5740 length arguments to start and end, for consistency.
5742 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
5744 * ioext.h: update prototypes.
5745 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
5746 scm_read_line_x, it's a more general procedure using an
5747 interface from scsh. read-line and read-line! are now defined
5749 Note that the new read-line trims the terminator
5750 by default, previously it was appended to the returned string. An
5751 optional argument specifies how to process the terminator (scsh
5752 compatible). For the old behaviour: (read-line port 'concat).
5753 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
5754 returns a pair, but is converted to multiple values if the scsh
5757 socket.h: update prototypes.
5758 * socket.c (scm_recvfrom): for consistency with other procedures,
5759 take start and end as separate optional arguments.
5760 (scm_recv, scm_recvfrom): don't allow the second argument
5761 to be a size, only a buffer. Change the scheme names to
5762 recv! and recvfrom!. Don't return the buffer.
5764 * ioext.h, posix.h: move prototypes too.
5765 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
5766 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
5767 "read.h" and "unif.h".
5768 * ioext.c: include "chars.h"
5770 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
5772 * dynl.c: The dynamic linking and module registration functions
5773 are now defined even when dynamic linking is not available for the
5774 host system. Some of their functionality can be done without
5775 dynamic linking; when it's really needed, they throw errors.
5777 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
5779 * configure.in: Only define DYNAMIC_LINKING when one of the system
5780 dependent functions is detected.
5781 * dynl.c (scm_dynamic_func): New function to get the address of a
5782 function in a dynamic object.
5783 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
5784 produced by scm_dynamic_func as the thing to call.
5786 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
5788 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
5789 (scm_register_module_xxx, scm_registered_modules,
5790 scm_clear_registered_modules): New functions.
5792 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
5794 * symbols.c (scm_sysintern): Renamed to
5795 scm_sysintern_no_module_lookup.
5796 (scm_sysintern): New function to take the place of the old
5797 scm_sysintern. It uses the current toplevel lookup closure to give
5798 the symbol its value. This is a temporary hack to put packages
5799 like gtcltk into their own module.
5800 (scm_can_use_top_level_lookup_closure_var): New variable to tell
5801 us whether `scm_top_level_lookup_closure_var' has been initialized
5803 * eval.c (scm_init_eval): Set it.
5805 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5807 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
5808 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
5810 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
5812 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
5813 scm_sys_dup): deleted: FD capability will be added to other
5815 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
5816 scm_fd_free, fd_smob, scm_intern_fd.
5817 (scm_open): renamed from scm_sys_open. Return a port instead of
5818 an FD object. Make the mode argument optional.
5819 (scm_sys_create): deleted, it's just a special case of open.
5820 (scm_init_filesys): move interning of constants O_CREAT etc.,
5821 here (were previously using SCM_CONST_LONG macro).
5822 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
5824 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
5825 include "fports.h" and <stdio.h>
5826 (scm_stat, scm_select): don't support FD objects.
5828 * error.h: adjust scm_syserror_msg prototype.
5829 * error.c (scm_syserror_msg): take an extra argument for errno.
5830 Using the global value didn't always work, since it could be
5831 reset by procedure calls in the message or args arguments.
5833 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
5834 I don't understand why the check was there (and what about the
5837 * strop.c (scm_string_copy): allow shared substrings to be copied.
5839 * unif.h: corresponding change to prototypes.
5840 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
5841 recognize two new optional arguments: offset and length. Allow
5842 the port argument to be an integer (file descriptor, for scsh).
5843 Include <unistd.h> for "read" prototype.
5845 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5847 * socket.c: don't include filesys.h.
5849 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
5851 * Makefile.am: add AWK=@AWK@ (?)
5853 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
5855 Add a rule to generate errnos.c from errnos.
5856 * error.c (scm_init_error): include errnos.c.
5857 * errnos_cnvt.awk: new file, converts the list of errno codes to
5859 * errnos_get.c: new file.
5860 * errnos.default: new file, contains errnos to try if they can't
5861 be extracted from errno.h.
5862 * configure.in: if using GCC, try and extract errno codes from
5866 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
5868 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
5869 * Makefile.am: Made libguile into a libtool library.
5870 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
5871 Set libtool_libs to indicate that libguile is a libtool library.
5872 See guile/ChangeLog for details.
5873 * .cvsignore: ignore "*.lo", the libtool library objects.
5875 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5877 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
5878 use htons in getservbyport argument.
5880 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5882 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
5883 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
5886 * objprop.c (scm_object_property): No need to take the CDR of the
5887 value returned by scm_object_properties, since Aug 20 change.
5889 * configure.in: When checking for struct linger, #include
5890 <sys/types.h> as well as <sys/socket.h>. I've never known
5891 <sys/types.h> to cause any portability problems, and Solaris's
5892 <sys/socket.h> needs it.
5893 * configure: Rebuilt.
5895 I think the Sun compiler has chosen a perverse way to interpret
5896 ANSI declarations combined with K&R definitions. We'll
5897 appease it a little bit. But when it invades France, we fight.
5898 * print.c (scm_iprlist): Change 'tlr' argument to an int.
5899 * print.h (scm_iprlist): Here too.
5900 * numbers.c (scm_divbigdig): Change definition to match
5901 declaration in numbers.h.
5902 * unif.c (scm_makflo): Change definition to match declaration in
5905 * init.c (scm_boot_guile): Don't return the value of
5906 scm_boot_guile_1. This function doesn't return a value;
5907 scm_boot_guile_1 doesn't return a value (or return at all).
5909 * eval.c (unmemocopy): Add a semicolon to appease the Sun
5912 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
5913 compile. I have a feeling this function is a bad idea anyway ---
5914 one should always test for features, not systems.
5916 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
5917 semicolons. Only pure luck kept this from being noticed earlier.
5919 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
5921 * socket.c (scm_recvfrom): Added missing semicolon.
5923 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5925 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
5926 the buffer and start and end positions for scsh networking
5929 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
5931 * configure.in: Revert previous change to this file; the problem
5932 is due to transient automake weirdness.
5933 * configure: Rebuilt.
5935 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
5936 PLUGIN/guile.libs. configure generates the latter from the former.
5937 * Makefile.in: Rebuilt.
5939 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
5940 need this if we install scripts, like guile-snarf.
5941 * configure: Rebuilt.
5943 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5945 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
5947 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
5949 * socket.c (scm_addr_vector): fix faulty scm_listify.
5951 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
5953 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
5954 style block comment is no longer considered an error.
5956 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
5958 * PLUGIN/guile.libs.in: New file.
5959 * PLUGIN/guile.libs: Removed from repository.
5960 * configure.in: Create PLUGIN/guile.libs from
5961 PLUGIN/guile.libs.in. This is for including additonal libraries
5962 needed for dynamic linking.
5963 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
5964 instead of PLUGIN/guile.libs.
5966 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
5968 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
5970 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
5971 occurrences of the given element from the list, not just the
5972 first. This is how the Emacs Lisp functions behave, how the
5973 analogous Common Lisp functions behave, and (I believe) how the
5974 older Maclisp functions worked. I realize that this change may
5975 break code, but it seemed better to break it before the Guile
5978 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
5979 Their prototypes were already present in gc.h, but they weren't
5981 (scm_init_storage): Initialize scm_protects.
5982 * root.c (scm_protects): New element of scm_sys_protects.
5984 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
5986 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
5988 * libguile.h: Added #include "libguile/net_db.h".
5990 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
5991 30 change. That file is only meant for communication between the
5992 configuration process and load.c. If code linked against libguile
5993 wants to get at the paths mentioned in libpath.h, it can call
5994 functions declared in load.h.
5996 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5998 * libguile.h: Removed #include "libguile/fdsocket.h"
6000 * net_db.c: Added #include <sys/socket.h>.
6002 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
6004 * filesys.c (scm_input_waiting_p): use select in preference to
6005 FIONREAD, since the latter doesn't detect EOF.
6006 Throw error if neither select nor FIONREAD available.
6008 * socket.c (scm_connect): take a port, not a fd object.
6009 (scm_fill_sockaddr): throw an error if fam is not recognised.
6010 (scm_bind): use scm_fill_sockaddr.
6011 (scm_listen): take a port, not a fd object.
6012 (scm_accept): take and return a port. return #f in the car if
6013 address can't be got
6014 (scm_sock_fd_to_port): new procedure.
6015 (scm_socket): use scm_sock_fd_to_port.
6016 (scm_addr_vector): throw error if unrecognised address type.
6017 take an extra argument with the calling procedure name.
6018 (scm_getsockname): take a port. return #f if address can't be got.
6019 (scm_getpeername): take a port. return #f if address can't be got.
6020 (scm_recvfrom): take a port. return #f for address component if can't
6022 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6023 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6025 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6027 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6028 use separate data pointers, to allow them to be designed
6029 independently and reused.
6030 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6031 Renamed from catch_body, catch_handler, and uncaught_throw; made
6033 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6035 (scm_catch): Use the above.
6036 (scm_throw): Don't bother printing a message for an uncaught
6037 throw; we establish a default handler in init.
6038 * throw.h (scm_internal_catch): Prototype updated.
6039 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6041 (struct scm_body_thunk_data): New structure, used as data
6042 argument to scm_body_thunk.
6043 * init.c (struct main_func_closure): New structure, packaging up
6044 the data to pass to the user's main function.
6045 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6046 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6047 scm_internal_catch to establish a catch-all handler, using
6048 scm_handle_by_message. This replaces the special-case code in
6050 (invoke_main_func): Body function for scm_internal_catch; invoke
6051 the user's main function, using the main_func_closure pointer to
6052 decide what to pass it.
6053 * root.c (struct cwdr_body_data): Remove handler_proc member.
6054 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6055 (cwdr_handler): Removed.
6057 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6059 * socket.h (SCM_P): update bind prototype.
6060 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6061 include "feature.h".
6062 (scm_socket): return a port, not a file descriptor object.
6063 include "fports.h" and <unistd.h>
6064 (scm_bind): take a port, not a file descriptor object.
6065 take an extra argument for address args.
6067 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6068 INADDR_NONE, INADDR_LOOPBACK.
6070 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6072 * init.c: include net_db.h and not fdsocket.h.
6073 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6075 * Makefile.am: corresponding changes.
6076 * socket.h: renamed from fdsocket.h, fix names.
6077 * net_db.h: renamed from socket.h, fix names.
6078 * socket.c: renamed from fdsocket.c.
6079 remove _sys from procedure names.
6080 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6081 add "socket" to features list.
6082 * net_db.c: renamed from socket.c.
6083 remove _sys from procedure names.
6084 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6085 add "net-db" to features list.
6086 include "net_db.h". don't include <sys/socket.h> or
6089 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6091 * tags.h (scm_tags): Removed comma at end of last enumerator.
6093 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6095 Don't use GCC extensions to allocate space for debugging frames.
6096 (Here he goes again! Why do we put up with this?!)
6097 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6098 an scm_debug_info structure, not an in-line array of them. Add
6099 'info' member, to say how many vect elements we've used, for eval
6101 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6102 a new variable debug_info_end to mark the end of vect, instead of
6103 the address of the 'info' pointer itself.
6104 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6105 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6106 (SCM_APPLY): Explicitly allocate space for debug.vect.
6107 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6108 * stacks.c: Adjusted for new debug frame structure.
6109 (RELOC_INFO, RELOC_FRAME): New macros.
6110 (stack_depth, read_frames): Use them, and new scm_debug_frame
6111 element 'info', instead of magically knowing that eval frames have
6112 an info pointer sitting after vect.
6113 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6115 (scm_init_stacks): Formatting tweaks.
6117 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6119 Give GCC more control flow information, so it can be sure that
6120 variables aren't used uninitialized.
6121 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6122 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6123 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6124 scm_misc_error): Tell GCC that these functions never return.
6125 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6126 out the field type, call abort if SCM_ASSERT returns, to placate
6128 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6129 scm_wta ever returns. We can't handle this case anyway, and this
6130 gives the optimizer more information.
6131 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6132 scm_wta ever returns.
6134 In some cases, the code is fine, but GCC isn't smart enough to
6135 figure that out; this usually happens when one variable is only
6136 initialized and used when a particular condition holds true, and
6137 we know that condition will never change within a given invocation
6138 of the function. In this case, we simply initialize the variables
6139 to placate the compiler, hopefully to a value which will cause a
6140 crash if it is ever actually used.
6141 * print.c (scm_iprin1): Initialize mw_pos.
6142 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6143 * throw.c (scm_ithrow): Initialize dynpair.
6144 * unif.c (scm_uniform_vector_ref): Initialize cra.
6145 * struct.c (init_struct): Initialize prot.
6146 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6148 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6149 if EXPR contains no expressions.
6151 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6153 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6154 cause an infinite loop (???). So much for the algebraic
6155 equivalency of variable-sized arrays and alloca...
6157 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6159 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6160 a SCM boolean, not a C boolean.
6162 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6164 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6165 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6166 rules for raising scm_mtrigger. Previously, unfortunate but not
6167 unlikely circumstances could result in almost constant invokation
6168 of the gc. Now, this situations should be less likely, but they
6169 are not prevented completely.
6171 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6173 * numbers.c (scm_fuck): Procedure removed; looks like old test
6175 * numbers.h: Prototype removed.
6177 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6179 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6180 array to a pointer, to match my Nov 21 change in eval.c.
6182 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6184 * libguile.h: Added #include "libguile/backtrace.h", #include
6185 "libguile/stacks.h".
6187 * strings.c (scm_string scm_make_string scm_string_ref
6188 scm_string_set_x scm_string_equal_p scm_string_append):
6189 Bugfix according to scm patch from Aubrey Jaffer:
6190 Corrected long-standing
6191 (not (eqv? (integer->char 128)
6192 (string-ref (make-string 1 (integer->char 128)) 0)))
6193 bug found by John Kozak <jk@noontide.demon.co.uk>.
6195 * strports.c, strports.h: Make scm_eval_0str return the value of
6196 the last expression evaluated (previously, it returned void).
6198 * strports.c, strports.h: New function: scm_read_0str. Does what
6201 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6203 * simpos.c (scm_getenv): return #f if string can't be found in the
6204 environment instead of throwing an exception, for compatibility
6205 with numerous other systems.
6207 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6209 * Makefile.am (.c.x): Use guile-snarf.
6210 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6212 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6214 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6216 * backtrace.c (scm_display_error_message): Made non-static, and
6217 renamed from display_error_message.
6218 * backtrace.h (scm_display_error_message): Added extern decl.
6219 * throw.c (uncaught_throw): Use it to display the error message.
6221 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6223 * inet_aton.c: Use #if 0, not #ifdef 0.
6225 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6227 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6228 to convert the returned value.
6229 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6230 the offset argument.
6232 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6234 Add new interface to catch/throw, usable from C as well as
6236 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6237 (scm_internal_catch): New function, replaces...
6238 (scm_catch_apply): Deleted.
6239 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6240 mechanism which is a bit more code, but can be used nicely from C
6241 and implement the Scheme semantics as well.
6242 (scm_internal_catch): This is the replacement; it's named after
6243 the analogous function in Emacs.
6244 (scm_catch): Reimplemented in terms of the above.
6245 (struct catch_body_data, catch_body, catch_handler): New
6246 functions, used by scm_catch.
6247 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6248 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6249 support for new cwdr.
6251 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6254 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6256 * acconfig.h: Added DYNAMIC_LINKING symbol.
6257 * configure.in: Add option and checks for dynamic linking.
6258 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6259 dynl.h: New files for dynamic linking support.
6260 * Makefile.am (libguile_a_SOURCES):
6262 (modinclude_HEADERS): Added "dynl.h".
6263 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6265 * init.c (scm_boot_guile_1): Call
6266 scm_init_dynamic_linking to initialize dynamic linking support.
6268 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6270 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6271 (as we Schemers say). It needs to be global, so that I can tweak
6272 it for the proper operation of unexec.
6273 (scm_boot_guile_1_live): New variable, see above.
6275 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6277 * guile-snarf.sh: Removed.
6278 * PLUGIN/guile.libs: Added dependency for -lm.
6279 * acinclude.m4: Renamed from aclocal.m4.
6280 * PLUGIN/greet: Removed.
6281 * Makefile.am, aclocal.m4: New files.
6282 * configure.in: Updated for Automake.
6284 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6286 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6287 and not top_level_lookup_thunk_var.
6289 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6291 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6293 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6295 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6296 Scheme function, instead of syntax. Single argument is now a
6299 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6301 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6302 scm_ra_divide): Properly terminate statements passed as arguments
6303 to IVDEP macros. (Thanks to Bernard Urban.)
6305 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6306 with non-constant sizes. (Thanks to Bernard Urban.)
6308 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6310 It's an "eval closure", not an "eval thunk." A thunk is a
6311 function of no arguments.
6312 * root.h (struct scm_root_state): Renamed
6313 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6314 (scm_top_level_lookup_closure_var): Renamed from
6315 scm_top_level_lookup_thunk_var.
6316 * root.c (mark_root): Uses changed.
6317 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6318 * init.c (scm_start_stack): Uses changed.
6319 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6320 Change scheme-visible name to *top-level-lookup-closure* from
6321 *top-level-lookup-thunk*.
6323 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6325 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6326 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6328 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6330 * gc.c (struct scm_heap_seg_data): Doc fixes.
6332 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6333 sweeping. Then, prepend each segment's free cells to its
6334 freelist, rather than wiping out the old value. (Thanks to Marius
6337 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6338 scm_check_freelist, scm_debug_newcell): New functions and
6339 variables, for debugging freelist problems.
6340 * pairs.h (SCM_NEWCELL): New debugging version added.
6341 * gc.h (scm_debug_newcell): Added extern declaration, used by
6342 debugging version of SCM_NEWCELL.
6344 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6346 On some systems <libc.h> conflicts with <unistd.h>, and should not
6347 be #included at all.
6348 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6349 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6350 * configure.in: Call it.
6351 * posix.c, filesys.c: Use its results to decide whether or not to
6353 * configure, scmconfig.h.in: Rebuilt with autoconf and
6356 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6358 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6359 pointer to the stdio stream before calling scm_setbuf0, so the
6360 latter will be able to retrieve it. I'm surprised this didn't
6361 segfault earlier. (Thanks to Christopher Lee.)
6363 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6365 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6368 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6370 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6371 number of stack narrowing specifier pairs. The first specifier in
6372 a pair controls inner border, the second the outer border. A
6373 number means cut that number of frames, a procedure object means
6374 cut until that object is found in operator position in a frame.
6376 * root.c (cwdr): Bugfix.
6378 * read.c: Recording of positions disabled by default.
6380 * procs.c (scm_closure_p): New function.
6382 * posix.c (scm_tmpnam): New function.
6384 * load.c: Added #include "throw.h".
6385 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6388 * load.c, load.h (scm_read_and_eval_x): New function.
6390 * eval.c: Renamed debug option "deval" to "debug".
6392 (scm_eval_x): `eval!' is no longer accessible from the scheme
6393 level. Motivation: We can't allow operations which introduce
6394 glocs into the scheme level. Guile's type system can't handle
6395 these as data. Use `eval' or `read-and-eval!' as replacement.
6397 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6398 SCM_CONSP since this is a macro!; Set vframe.prev to
6399 scm_last_debug_frame instead of 0. In this way we can look
6400 "above" the virtual start stack frame if we wish.
6401 (scm_debug_hang): New function: Useful for debugging Guile in
6402 certain tricky situations. Will probably be removed later...
6404 * debug.h: Changed semantics of debug option "backtrace". This
6405 option now only indicates whether we want automatic backtrace at
6408 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6410 * ports.c: #include "filesys.h"
6411 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6413 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6414 Motivation: This is system specific code which is related to file
6415 I/O. It also may use select. Added code by Gary Houston to
6416 detect presence of character in stdio buffers.
6418 * libguile.h: #include "libguile/libpath.h"
6420 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6421 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6422 SCM_SITE_DIR; Install libpath.h among the other include files.
6424 * load.c, load.h (scm_sys_package_data_dir): New function.
6426 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6428 * stacks.h: Bugfix: Don't use tail-array length field as stack
6429 length field! This screwed GC.
6431 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6433 * _scm.h: Added #ifndef around definition of macros min and max.
6435 * __scm.h: Added hooks for threads to plugin to in ints protection
6436 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6437 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6438 the main code in these macros duplicated and spread over multiple
6439 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6440 SCM_THREAD_SWITCHING_CODE.
6442 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6444 * snarf.h: New file.
6445 * guile-snarf.sh: New file.
6446 * Makefile.in (inner_h_files): Added snarf.h
6447 (ancillary, install, uninstall, distclean): Added actions for
6449 (.c.x): Use guile-snarf.
6450 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6451 (gen_c_files): Note that these depend on guile-snarf.
6452 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6453 now in "snarf.h". Added #include "snarf.h" to get them.
6454 * libguile.h: Added #include "snarf.h".
6455 (Patches applied and tweaked by Jim Blandy.)
6457 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6459 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6460 standards suggest against providing prototypes for system
6461 functions. Thanks to Greg Troxel.
6463 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6465 * strports.c (scm_eval_0str): New function.
6466 #include "read.h", to get prototype for scm_read.
6467 * Makefile.in (strports.o): Update dependencies.
6468 * strports.h: New prototype.
6470 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6471 scheme name from "int?" to "integer?". It seems to do the job.
6472 * numbers.h: Rename prototype too.
6473 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6476 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6477 scm_num_eq_p): Rename these according to R4RS conventions: call
6478 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6479 to making libguile R4RS compliant without ice-9...
6481 * load.c (scm_sys_search_load_path): Search for files under all
6482 extensions listed in the %load-extensions variable. If FILENAME
6483 is absolute, return it unchanged, without searching the load path.
6484 (scm_loc_load_extensions): New variable, pointing to
6485 %load-extensions' value cell.
6486 (scm_init_load): Initialize it, and the value it points to.
6487 (scm_primitive_load_path): Improve error reporting.
6489 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6490 of new Scheme variable %load-hook.
6491 (scm_primitive_load): Apply %load-hook to filename.
6493 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6495 * configure.in: add tests for figuring out whether buffered data
6496 is available in a FILE structure, which is needed by char-ready.
6498 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6501 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6502 exceptions using misc_error instead of syserror. It seems a bit
6503 odd to throw an exception if a string can't be found in the
6504 environment, but it's consistent with open-file, stat etc.
6505 (simpos.h): remove sys_ from getenv.
6507 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6508 occurs, throw an error instead of returning errno. Return value
6510 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6512 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6514 * filesys.c (scm_stat2scm): derive file type and permissions from
6515 the stat mode and append them to the returned vector.
6516 There isn't much overhead in doing this and it avoids the need to
6517 work with S_IRUSR et al. in Scheme.
6518 Define symbols scm_sym_regular etc.
6519 (scm_init_filesys): don't intern S_IRUSR etc.
6521 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6522 and s_primitive_load_path.
6524 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6526 * error.h: don't declare error symbols. prototype for scm_misc_error.
6528 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6531 * error.c: use SCM_SYMBOL to set up error keys.
6532 scm_misc_error: new procedure.
6534 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6536 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6537 between `#!' and `!#' is ignored.
6538 (skip_scsh_block_comment): New function.
6540 * feature.c (scm_set_program_arguments): New argument, FIRST.
6541 * feature.h: Update prototype.
6542 * init.c (scm_boot_guile_1): Pass new argument to
6543 scm_set_program_arguments.
6545 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6547 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6548 (scm_boot_guile): Call scm_set_program_arguments here, later than
6549 the old initialization.
6551 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6552 initialization procedure.
6553 - Delete in, out, err arguments; there are other perfectly good
6554 ways to override these when desired.
6555 - Delete result argument; this function shouldn't ever return.
6556 - Rename init_func argument to main_func, for less confusion.
6557 - Delete boot_cmd argument; main_func is more general.
6558 -Add 'closure' argument, to help people pass data to main_func
6559 without resorting to global variables.
6560 - Abort if reentered; don't bother returning an error code.
6561 - Call scm_init_standard_ports to set up the default/current
6562 standard ports; no need to pass them to scm_start_stack.
6563 - Remove code to evaluate the boot_cmd, and start the repl; let
6564 the user do something like that in main_func if they want.
6565 - Remove code to package up a return value; main_func can do any
6567 - Call exit (0), instead of returning.
6568 (scm_start_stack): Don't initialize the I/O ports here; that's
6569 weird. Delete in, out, err arguments. Move guts to
6570 scm_init_standard_ports, scm_stdio_to_port.
6571 (scm_init_standard_ports): New function, to set up current and
6572 default standard ports.
6573 (scm_start_stack, scm_restart_stack): Make these static.
6574 * init.h (scm_boot_guile): Adjust declaration.
6575 (scm_start_stack, scm_restart_stack): Remove externally
6576 visible declarations for these.
6577 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6579 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6580 written out several times in scm_start_stack.
6581 * fports.h: New declaration for the above.
6583 * feature.c (scm_set_program_arguments): New function.
6584 * feature.h: New declaration for the above.
6586 * ports.c: Formatting tweak.
6588 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6590 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6591 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6592 for obtaining the address of a car or cdr field. Motivation:
6593 &SCM_CXR make assumptions about the internal structure of the
6596 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6597 Motivation: see SCM_CXRLOC.
6599 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6600 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6601 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6602 Motivation: Safer use. Some other macros are defined in terms of
6603 these operations. If these are defined using the SCM_SETCXR
6604 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6605 to inefficiency and an <e1> with side-effects could potentially
6606 break. Also, these particular operations are heavily utilized in
6607 the garbage collector. In unoptimized code there will be a
6610 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6611 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6612 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
6613 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
6614 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
6615 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6616 vports.c: Cleaned up use of pairs: Don't make any special
6617 assumptions about the internal structure of selectors and
6618 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6619 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
6620 (Among other things, this change makes it easier to build Guile
6621 with certain compilers which have problems with casted lvalues.)
6623 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6625 * stacks.c: Improve selection of relevant stack frames when making
6626 a stack object. Introduce one level of indirection in the stack
6627 object to make it possible to "narrow" to a certain region of the
6628 stack. This facilitates making use of more clever algorithms (not
6629 implemented) for selecting relevant frames and gives a cleaner
6630 design since selection of frames can be done independently of
6631 extraction of frames from the real stack.
6632 (scm_stack_id): Also take #t as argument which means look at
6635 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
6636 Turn n_tail into an integer directly representing current number
6637 of frames in stack. Add field tail.
6639 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
6641 * debug.c (scm_make_memoized): Made it available at scheme level.
6642 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
6643 SCM_NIMP before applying heavier predicates in argument checking.
6644 (scm_local_eval): Also take memoized object as argument.
6646 * backtrace.c (scm_display_error): Just a safety measure: Stacks
6647 aren't created with zero length, but should such a strange
6648 creature suddenly turn up...
6650 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
6652 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
6653 `del', for the sake of C++ compilers. (Patch applied by JimB.)
6655 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
6657 * variable.c (scm_make_variable): Make the name hint optional, as
6659 (anonymous_variable_sym): Renamed from variable_sym. All uses
6662 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
6663 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
6664 of scm_primitive_load_path was also changed to
6665 "primitive-load-path", from "%try-load-path". Callers changed.
6666 We'd like to respect the convention that a function named
6667 "try-mumble" should behave just like the function called "mumble",
6668 but return #f instead of signalling some error.
6669 * load.h: Rename prototypes.
6671 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6673 * print.c (make_print_state, grow_print_state), print.h: Modified
6674 the print state representation: Don't use a tail array for
6675 recording of circular references. Resizing of the print state
6676 structure invalidates the print state pointer. To avoid passing
6677 around an indirect print state reference to all printing
6678 functions, we instead let the print state reference a resizable
6681 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
6683 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
6684 Don't crash when passed an improper list terminated by a
6685 non-immediate value.
6687 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
6689 Allocate data for structures on an eight-byte boundary, as
6690 required by the tagging system.
6691 * struct.c (alloc_struct): New function.
6692 (scm_make_struct, scm_make_vtable_vtable): Call it.
6693 * struct.h (scm_struct_n_extra_words): Bump to 3.
6694 (scm_struct_i_ptr): New "field".
6695 * gc.c (scm_gc_sweep): When we need to free the data, use the
6696 information stored by alloc_struct to find the beginning of the
6697 block allocated to the structure, so we can free it.
6699 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6701 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
6704 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
6705 (scm_debug_info): New member: id.
6707 * stacks.c: Stacks are now represented as structs; Stacks have an
6708 id given to them by `start-stack'.
6709 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
6711 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
6712 Changed stack representation.
6714 * debug.c (scm_procedure_name): Try procedure property `name' for
6715 compiled closures aswell.
6717 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
6719 * eval.c: scm_i_name moved to gsubr.c
6720 (scm_m_define): Record names of all kinds of procedure
6721 objects. (Earlier, only closures were recorded.)
6723 * procprop.h: Added declaration of scm_i_name.
6725 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
6726 (scm_make_gsubr): Record names of compiled closures.
6728 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6730 * debug.c, debug.h: Removed obsolete code.
6732 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
6733 stacks.c: Renamed regs --> scm_contregs.
6735 * print.c (scm_free_print_state): Cleanup print state before
6736 returning it to pool. It is better to do it here than in
6737 scm_prin1 since scm_prin1 is called often.
6739 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
6740 s_set_source_property_x): Check that first argument is a pair or a
6743 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
6744 scm_i_line, scm_i_column and scm_i_breakpoint global.
6746 * init.c: Added #include "backtrace.h" and #include "stacks.h".
6747 (scm_boot_guile_1): Added calls to scm_init_backtrace and
6750 * debug.h: Added debug object smob declaration and macro
6753 * configure.in: Build with backtrace.o and stacks.o if debug
6756 * Makefile.in: Added entries for new files: backtrace.c,
6757 backtrace.h, stacks.c and stacks.h.
6759 * symbols.c (scm_sym2ovcell): Fixed documentation.
6761 * _scm.h (min, max): Added.
6763 * async.c: Moved `min' macro to _scm.h.
6765 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
6766 SCM_BACKTRACE_INDENT.
6768 * eval.c: Added new debug options `maxdepth' and `indent'.
6770 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
6772 * print.h: Added selector SCM_PRINT_STATE.
6774 * print.c: New functions: scm_make_print_state,
6775 scm_free_print_state.
6777 * print.h: Added declarations for scm_make_print_state,
6778 scm_free_print_state.
6780 * debug.c (scm_m_start_stack): New acro.
6782 * debug.h: Small cleanup.
6784 * init.c (scm_boot_guile_1): Moved scm_init_debug below
6787 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

6814 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
6815 * ports.h (ptobfuns): Added prototypes. This means some casting in
6817 * fports.c: Added casts for initializations, since the functions
6818 are defined to take FILE * as their stream argument, not SCM.
6819 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
6820 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
6821 to `char *str_data' to conform to prototype.
6823 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6825 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
6827 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
6829 * stime.c, stime.h: use SCM_P method.
6831 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6833 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
6834 be given at least two arguments. Insist that lst's last element
6835 be a list, but don't make any requirements of its predecessors.
6837 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6839 * eval.c (scm_nconc2last): Revert last change; there seems to be
6840 other stuff going on here.
6842 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
6844 * eval.c (scm_nconc2last): Make sure that each element of lst
6845 (which is a list of argument lists, except for the tail) is a
6846 proper list, i.e., finite and terminated by '().
6848 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6850 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
6853 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
6854 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
6857 * vectors.c (scm_make_vector): Fill vectors with the undefined
6858 value, to help make Guile Scheme code more portable to other
6861 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
6862 * symbols.h, tags.h: Doc fixes.
6864 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
6866 * async.c (scm_take_signal): Doc fixes.
6868 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
6870 * numbers.c (scm_divbigint): When the remainder is zero, we don't
6871 want to subtract it from the modulus; we just want to leave it
6874 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
6876 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
6879 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
6881 * throw.c (scm_catch_apply): Finished implementation of
6884 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6886 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
6888 (scm_init_filesys): set "i/o-extensions" feature.
6891 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
6893 * Makefile.in (root.o): Correct dependencies.
6895 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
6897 * Makefile.in: Added dependency entry for root.o.
6899 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
6900 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
6902 * init.c (scm_start_stack): Set initial root continuation number
6905 * procs.c: New function: scm_thunk_p.
6907 * procs.h: Added declarations of scm_thunk_p.
6909 * root.c: Renamed `call-with-new-root' -->
6910 `call-with-dynamic-root'.
6911 (cwdr): Removed allocation of new root state. This should be done
6912 separately by use of scm_make_root.
6913 (scm_apply_with_dynamic_root): New function: Does what it
6914 sounds like. Needed when spawning threads.
6916 * root.h: Added member last_debug_frame to root state.
6917 Added #include "libguile/debug.h"
6919 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
6920 arguments. The motivation is that code in root.c needs catch
6921 functionality, and we want to avoid code duplication.
6922 New functions: scm_catch, scm_lazy_catch. These are wrappers for
6923 scm_catch_apply. scm_lazy_catch is intended to introduce catch
6924 handlers that run without popping the stack into the dynwind
6927 * throw.h: Added prototypes for scm_catch_apply and
6930 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6932 * root.h (scm_root, scm_set_root): Decouple thread support details
6933 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
6934 SCM_SET_THREAD_LOCAL_DATA.
6936 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
6937 and tortoise scanning loop.
6939 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
6941 * Makefile.in: Rebuild dependencies.
6943 * libguile.h: #include "libguile/print.h" before "smob.h", since
6944 the latter uses the print_state structure.
6946 * throw.c (scm_ithrow): Use the correct variable when checking to
6947 see if a given element of scm_dynwinds is a valid catch.
6949 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
6950 structure, abort; don't just silently ignore the garbage.
6952 * _scm.h: #include "print.h" here, since it seems to be used just
6954 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
6955 strports.c, unif.h: Don't #include "print.h".
6957 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6959 * feature.h (scm_loc_features): Removed external declaration.
6960 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
6962 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6964 * feature.c (scm_init_feature): Added threads feature (needs to be
6965 initialized here, since features doesn't exist when
6966 scm_init_threads is called).
6968 * libguile.h: Added #include "libguile/../threads/threads.h".
6969 (This is a kludge to get thread support working. This should be
6972 * configure.in, acconfig.h: Added flags for thread support.
6974 * scmsigs.c: Define `signal' to be `pthread_signal' if using
6977 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
6978 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
6981 * _scm.h: Added conditional #include "threads.h"
6983 * __scm.h (SCM_ASYNC_TICK): Added call to macro
6984 SCM_THREADS_SWITCHING_CODE.
6986 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
6987 allocate the basic dynamic root object.
6988 (scm_boot_guile): Added call to scm_init_root.
6990 * root.c, root.h: Added root smob.
6991 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
6992 functions: Implements dynamic roots mostly according to spec in
6993 SCM manual. Main difference is that the second argument is a
6994 throw handler rather than an error "thunk".
6996 * root.h: Added declaration of scm_init_root.
6998 * root.c: Added #include "genio.h", #include "smob.h", #include
6999 "pairs.h", #include "throw.h", #include "dynwind.h", #include
7001 (scm_init_root): Added #include "root.x".
7003 * throw.c: Added #include "stackchk.h"
7004 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
7005 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
7006 can be used in scm_call_with_new_root; Added reenabling of stack
7007 checking when catching a throw.
7009 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
7011 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
7013 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
7014 element is not found, as per R4RS.
7016 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7018 * list.c: Doc fixes throughout.
7020 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7022 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7023 declare the char * to be const. Avoids a warning in rgx.c.
7025 * ports.h: spelling fix.
7027 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7030 * load.c (scm_sys_try_load_path): throw an error if file not found
7031 (like it says it in NEWS).
7033 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7035 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7036 PROPS slot to '(), not #f; it's an empty alist.
7038 * throw.h, throw.c: Use SCM_P instead of #if hair.
7040 Remove special support for uncaught throws; see throw.c for
7042 * throw.c (uncaught_throw): New function.
7043 (scm_ithrow): Call uncaught_throw if we don't find a throw
7044 target; don't mess with scm_bad_throw_vcell.
7045 (scm_bad_throw_vcell): Variable deleted.
7046 (scm_init_throw): Don't initialize it.
7048 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7051 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7053 * numbers.c (scm_istr2int): If the number is short (as most
7054 numbers are), just call scm_small_istr2int to deal with it.
7055 (scm_small_istr2int): New function, created by un-#ifdefing the
7056 non-bignum version of scm_istr2int and renaming it.
7058 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7060 * load.c (scm_sys_try_load): don't check whether value returned
7061 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7062 Change the Scheme name from %try-load to primitive-load.
7064 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7065 Can avoid passing a message, allowing it to be derived in the
7066 error handler (e.g., if we want to throw to the key both from
7069 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7071 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7072 references now have a new appearance which is more compact and
7073 also gives a clue about what the target of the reference is.
7074 By setting parameters in the print state, more fancy printing can
7075 be achieved. This is used by the (not yet commited) backtrace
7078 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7080 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7083 * print.c: Added #include "struct.h". Removed function
7086 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7087 scm_iprin1. Removed prototype for scm_prlist.
7089 * arbiters.c (prinarb),
7090 async.c (print_async),
7091 debug.c (prindebugobj, prinmemoized),
7092 eval.c (prinprom, prinmacro),
7093 filesys.c (scm_fd_print, scm_dir_print),
7095 mallocs.c (prinmalloc),
7096 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7097 smob.h (scm_smobfuns),
7098 srcprop.c (prinsrcprops),
7100 unif.c, unif.h (scm_raprin1, rapr1),
7101 variable.c (prin_var): Changed argument `int writing' to
7102 `scm_print_state *pstate'.
7104 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7105 that it will be called before scm_init_print.
7107 * print.c (scm_prin1): Print states are now allocated when calling
7108 scm_prin1 and then passed around to all printing functions as an
7109 argument. A cache `print_state_pool' enables reuse of print
7111 (scm_make_print_state): New function.
7112 (scm_iprin1): Adaption to print states.
7113 (scm_iprlist): An initial "hare and tortoise" scan brings down
7114 time complexity to O (depth * N). (Better time complexity will be
7115 achieved when the printing code is completely rewritten.)
7117 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7119 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7120 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7121 it gets done whether or not the cache variable has a value.
7123 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7125 Distinguish #f and ().
7126 * __scm.h: #undef SICP.
7127 * pairs.h (SCM_EOL): Delete this definition, equating it with
7129 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7130 the value it used to have. Doc fixes, too.
7132 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7134 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7135 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7136 Lord's implementation of structs, allowing for tail arrays as
7137 described in the manual. Also fixed some bugs. (Both the interface
7138 and the implementation should be improved.)
7140 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7142 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7143 People who whish to see the source can do `(print-enable 'source)'.
7144 Removed #ifdef DEBUG_EXTENSIONS.
7146 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7148 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7149 integer (assuming for now accepting an integer is a good thing).
7151 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7152 %S will be used instead for write'ing arguments.
7154 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7155 asserts. fix a few other asserts.
7156 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7157 scm_uniform_vector_ref, scm_array_set_x,
7158 scm_dimensions_to_unform_array): change args in
7159 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7160 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7161 scm_substring_fill_x): likewise.
7162 gsubr.c (scm_gsubr_apply): likewise.
7163 eval.c (SCM_APPLY): likewise.
7165 * eval.c (4 places): replace scm_everr with lgh_error or
7168 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7169 scm_memory_error): new procedures.
7170 scm_everr: deleted. can use scm_wta, dropping first two args.
7171 scm_error: convert NULL subr to SCM_BOOL_F.
7173 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7176 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7179 * error.c, error.h: new error keys: scm_arg_type_key,
7180 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7182 scm_wta: reimplement using lgh_error instead of scm_everr.
7184 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7186 * gdbint.c: scm_lread now has one more argument.
7188 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7189 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7190 loading source from non-file ports, which, e. g., happens when
7191 using the Emacs interface).
7193 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7196 * read.c: Added code for recording of positions of source code
7197 expressions; New functions: recsexpr, scm_lreadrecparen;
7198 _scm_make_srcprops --> scm_make_srcprops
7199 (scm_flush_ws): Removed updating of positions counters. This work
7200 is already done by scm_gen_getc
7202 * read.h: Added prototype for scm_lreadrecparen
7204 * print.c: Added #include "alist.h"
7206 * eval.c: Added #include "hash.h"
7208 * eq.c: Added #include "ramap.h"
7210 * options.c: Documentation fixes.
7212 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7213 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7214 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7215 --> scm_make_srcprops
7217 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7218 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7219 function calls in the definition of the whash access macros.
7221 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7223 * init.c (scm_boot_guile): Add level of indirection to
7224 scm_boot_guile_1() to ensure that stack base pointer is properly
7225 initialized. There was no guarantee that variable i was the
7226 highest/lowest variable on stack (i.e. the call frame of
7227 scm_boot_guile was not completely protected from gc).
7229 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7231 * ports.h (scm_port_table): put back file_name, it will be used to
7232 support debugging. Undo related changes in fports.c, ioext.c,
7235 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7237 * ports.h (scm_port_table): remove file_name member for now, it seems
7239 * fports.c (scm_open_file): don't set file_name in PTAB.
7240 (prinfport): don't use file_name in PTAB.
7241 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7242 * ports.c (scm_add_to_port_table): don't intialize file_name.
7243 (scm_port_file_name): remove for now.
7244 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7246 * fports.h (scm_mkfile): prototype deleted.
7247 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7249 * debug.c, unif.c: use scm_out_of_range instead of
7250 wta for range errors (ASSERT still needs work).
7252 * error.c, error.h (scm_out_of_range): new procedure.
7254 * error.c, error.h (scm_out_of_range_key): new key.
7256 * posix.c (scm_sync): #else was missing.
7258 * error.c, error.h: append _key to names scm_num_overflow and
7261 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7262 of consing an empty list.
7263 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7264 of macros, saves code and string space.
7265 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7266 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7267 lower case. Rename scm_syserror_m to scm_syserror_msg.
7268 error.h: prototypes for new procedures.
7270 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7272 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7274 * error.c, error.h: setup scm_num_overflow key.
7276 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7277 Remove definition of SCM_OVSCM_FLOW.
7279 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7281 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7282 explicit message and args.
7284 * error.c, error.h, __scm.h: change system_error_sym to
7287 * error.c (system_error_sym): remove leading %% from the Scheme name
7290 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7292 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7294 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7295 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7296 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7297 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7298 renamed. (These were introduced by unsupervised name
7301 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7303 * print.c: Added code for detection of circular references during
7304 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7305 a hook for printing of closures (accessible via print options).
7306 This leads to a split of calls to scm_iprin1 into two classes:
7307 elementary print operations (e. g. the code which prints a smob)
7308 still use scm_iprin1 while top level calls (like scm_display) use
7309 scm_prin1. scm_prin1 begins by clearing the data structure used
7310 to record reference information.
7312 * print.h: Added declarations of scm_prin1 and scm_prlist.
7314 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7316 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7318 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7320 * error.c (err_head): scm_iprin1 --> scm_prin1
7322 * debug.c: Adjusted header comment.
7326 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7328 * strerror.c: Doc fix.
7330 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7332 * gdbint.c (gdb_read): Now possible to run during GC.
7333 (unmark_port, remark_port): New functions.
7335 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7337 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7338 of allocating a new string object. Also, increase size by
7339 the factor 2 instead of 1.5.
7341 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7343 * __scm.h (SCM_P): Corrected to run under traditional C.
7345 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7348 * async.c: Calls to scm_sysintern corrected.
7350 * async.h (scm_async_clock): Redundant declaration removed.
7352 * continuations.c (scm_dynthrow): Redundant declaration removed.
7354 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7355 Definition typos corrected.
7357 * debug.h: Missing declarations of functions in debug.c added
7360 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7361 Missing declarations to functions in eval.c added.
7363 * filesys.c: Possibly uninitialized variable rv.
7365 * gc.h (scm_object_addr, scm_unhash_name): Missing
7366 declarations of functions defined in gc.c added.
7368 * genio.c: Possible typos str_data -> wstr_data. ???
7370 * genio.c: Possibly unintended shadowing of local variable
7371 `int c' (gotos out of scope of inner `c'). ???
7373 * init.c: Uninitialized `SCM last' may be used.
7375 * ioext.h: (scm_sys_isatty_p): Typo.
7377 * list.h (scm_list_head): Missing prototype for function in
7380 * numbers.c (scm_two_doubles): Changed from extern to static
7381 (is used only within numbers.c).
7383 * numbers.h: Repeated declarations removed.
7385 * ports.h (scm_close_all_ports_except): Declaration for the
7386 function defined in ports.c added.
7388 * posix.h: Missing declarations added.
7390 * procs.h (scm_make_subr_opt): Missing declaration added.
7392 * socket.h (scm_sys_gethost): Missing declaration added.
7394 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7396 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7397 Missing declarations added.
7399 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7401 * struct.c: Uninitialized variable `SCM answer' may be used.
7403 * unif.c (l2ra): Declaration prototype.
7405 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7406 defined in ramap.c).
7408 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7409 Redundant declarations removed (they are in ramap.h).
7411 * variable.h (scm_make_udvariable,
7412 scm_make_undefined_variable): Declaration corrected to
7413 correspond variable.c.
7415 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7416 Missing declarations added.
7418 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7420 * Makefile.in (distclean): Don't forget to delete fd.h.
7422 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7424 * fd.h.in, tags.h: Trivial cleanups.
7426 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7427 marksweep.h just declared functions from gc.c.
7428 * gc.h, libguile.h: Don't #include "marksweep.h".
7429 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7430 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7431 dependencies updated.
7433 * libguile.h: Don't #include "files.h"; it's been deleted.
7435 * files.c (scm_sys_delete_file): Moved to filesys.c.
7436 File is now empty; deleted.
7438 * filesys.c: scm_sys_delete_file is now here. Remove
7439 #if's; they seem to rely on remnants of an old portability
7440 regimen. If the problems come up again, solve them properly,
7441 using autoconf. Specifically: Don't test M_SYSV, and #define
7442 remove to be unlink if it's #defined; don't use remove just
7443 because HAVE_STDC_HEADERS is #defined.
7444 * filesys.h: Add declarations for scm_sys_delete_file.
7445 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7446 files.o, files.h, files.c, and files.x.
7447 * init.c: Don't #include "files.h", and don't call scm_init_files.
7449 Use SCM_P instead of PROTO; the latter intrudes on the user's
7451 * params.h: Deleted; definition of SCM_P moved to...
7452 * __scm.h: ... here, where it replaces PROTO macro.
7453 * libguile.h, smob.h: Don't #include "params.h".
7454 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7455 smob.h: Fix prototypes accordingly.
7456 * Makefile.in: Update dependencies.
7457 (inner_h_files): Remove params.h.
7459 * gc.c: #include "gc.h"; every module should include its header,
7460 to let the compiler cross-check the declarations against the
7463 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7464 simpos.h: #include "libguile/__scm.h".
7466 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7468 * init.c: Don't forget to #include smob.h and init.h.
7469 * Makefile.in: Dependencies updated.
7471 * smob.h: Use PROTO instead of #if __STDC__.
7473 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7475 * __scm.h: Doc fixes.
7477 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7478 <angles>; this allows `make depends' to work properly.
7480 * libguile.h: #include smob.h and pairs.h before the others; they
7481 define typedefs used by other headers.
7483 C files should #include only the header files they need, not
7484 libguile.h (which #includes all the header files); the pointless
7485 recompilation was wasting my time.
7486 * Makefile.in (all .o dependency lists): Regenerated.
7487 * libguile.h: Don't try to get a definition for size_t here...
7488 * __scm.h: Do it here.
7489 * _scm.h: Since this is the internal libguile header, put things
7490 here that all (or a majority) of the libguile files will want.
7491 Don't #include <libguile.h> here; that generates dependencies on
7492 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7493 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
7494 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

7591 * weaks.c: Get "weaks.h".
7593 * stackchk.h: #include "libguile/debug.h",
7595 * print.h, read.h: #include "options.h", since everyone who uses
7596 either of these files will need that.
7598 * smob.h: #include "ports.h", "genio.h", and "print.h", since
7599 anyone who uses this file will need them to define the smob
7600 printing functions. Also, get markers.h, since people will need
7601 to #define the mark functions.
7603 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
7604 * ports.h: ... to here.
7606 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7607 don't rely on archaic C default type rules.
7609 * fports.h: #include "libguile/ports.h", since you need that in
7610 order to parse this.
7612 * genio.h: #include "libguile/print.h", because you need that to
7613 parse this; don't bother #including "ports.h", since print.h gets
7616 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7618 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7619 this; it's now a reference to an element of *scm_root.
7621 * debug.h: Don't #include "options.h"; the compiler won't be able
7622 to find that once the headers are installed; instead, #include
7623 "libguile/options.h".
7624 * gc.h: Same, with marksweep.h.
7625 * mbstrings.h: Same, with symbols.h.
7626 * scmhob.h: Same, with _scm.h.
7627 * smob.h: Same, with params.h.
7629 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
7630 C files; there's no need for this, and it forces recompilations
7633 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
7635 * error.c (scm_error): declare scm_error_callback.
7637 * error.h: prototype for scm_error_callback.
7639 * __scm.h: define lgh_error.
7640 (SCM_SYSERROR): redefine using lgh_error.
7642 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
7644 * error.c (scm_error): new procedure.
7646 * error.h: prototype for scm_error.
7648 * Makefile.in (install): install scmconfig.h from the current
7649 directory, not $(srcdir).
7651 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7653 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7654 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7655 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,

7661 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7662 vports.h, weaks.h: #include "libguile/__scm.h", not
7663 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
7664 dependencies are within libguile properly.
7666 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7668 * Makefile.in (.c.x): Simplify; there's no need to run this rule
7669 when scmconfig.h doesn't exist.
7671 * load.c (scm_sys_try_load): Correct spelling.
7673 * feature.c (scm_loc_features): Make this static.
7675 * Makefile.in (libpath.h): Omit trailing slash from path. We
7676 shouldn't require it of users, so why put it here?
7678 Move code to initialize and search %load-path from ice-9 to C
7679 code, so we can use the load-path to find the ice-9 boot code;
7680 this makes it easier to run Guile without installing it. See
7681 corresponding changes in guile/Makefile.in.
7682 * feature.c: Move stuff concerned with the load path to load.c.
7683 (scm_compiled_library_path): Deleted.
7684 Don't #include libpath.h here.
7685 * feature.h: Don't mention scm_compiled_library_path.
7686 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
7687 <sys/stat.h>, and <unistd.h> (if present).
7688 (R_OK): #define if the system hasn't deigned to.
7689 (scm_loc_load_path): New variable.
7690 (scm_init_load_path, scm_sys_search_load_path,
7691 scm_sys_try_load_path): New functions.
7692 (scm_init_load): Initialize scm_loc_load_path to point to the
7693 value cell of the Scheme %load-path variable.
7694 * load.h: Add declarations for scm_sys_search_load_path,
7695 scm_sys_try_load_path.
7696 * init.c: Call scm_init_load_path.
7697 * Makefile.in (feature.o, load.o): Dependencies updated.
7699 * load.c, load.h: Rewrite using PROTO macro.
7701 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7703 * gc.c (scm_cellp): New function: C predicate to determine if an
7704 SCM value can be regarded as a pointer to a cell on the heap.
7706 * gc.h: Added declaration of scm_cellp.
7708 * gdb_interface.h: New file: The GDB interface header from the GDB
7711 * gdbint.c: New file: GDB interface.
7713 * gdbint.h: New file: GDB interface.
7715 * libguile.h: Added #include <libguile/gdbint.h>.
7717 * init.c (scm_boot_guile): Added scm_init_gdbint.
7719 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
7720 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
7721 found if object files and source are kept separate).
7723 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
7725 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
7727 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
7729 * configure.in: Don't substitute the values of TCL_SRC_DIR and
7730 TK_SRC_DIR; they're not relevant any more.
7732 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
7733 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
7735 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
7737 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
7738 search path, so we can find the <libguile/MUMBLE.h> headers.
7740 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
7742 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
7743 implicit in the .c.o rule.
7744 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
7747 Put the library path in a header file, instead of passing it on
7748 the command line in every compilation.
7749 * Makefile.in (libpath.h): New target.
7750 (feature.o): Depend on libpath.h.
7751 (clean): Delete libpath.h.
7752 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
7753 * feature.c: ... #include "libpath.h" here.
7754 * .cvsignore: Ignore libpath.h.
7756 Don't install the unwashed masses of Guile header files in the
7757 main #include path; put most of them in a subdirectory called
7758 'libguile'. This avoids naming conflicts between Guile header
7759 files and system header files (of which there were a few).
7760 * Makefile.in (pkgincludedir): Deleted.
7761 (innerincludedir): New variable; this and $(includedir) are enough.
7762 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
7763 (installed_h_files): Divide this up. Now this variable lists
7764 those header files which should go into $(includedir) (i.e. appear
7765 directly in the #include path), and ...
7766 (inner_h_files): ... this new variable says which files appear in
7767 a subdirectory, and are referred to as <libguile/mumble.h>.
7768 (h_files): List them both.
7769 (install): Create innerincludedir, not pkgincludedir. Put
7770 the installed_h_files and inner_h_files in their proper places.
7771 (uninstall): Corresponding changes.
7772 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7773 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7774 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
7775 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
7776 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
7777 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
7778 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
7779 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
7780 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7781 vports.h, weaks.h: Find __scm.h in its new location.
7782 * __scm.h: Find scmconfig.h and tags.h in their new locations
7783 (they're both "inner" files).
7785 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
7787 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
7789 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7791 * posix.c: Doc fixes.
7793 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
7795 * socket.c: Don't include a prototype for inet_aton; just use a
7796 K&R style declaration, to avoid warnings but minimize the chance
7797 of conflicts with the system.
7799 On NextStep, <utime.h> doesn't define struct utime, unless we
7800 #define _POSIX_SOURCE before #including it.
7801 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
7802 * acconfig.h: New comment text for above CPP symbol.
7803 * configure.in: Call it.
7804 * posix.c: #define _POSIX_SOURCE if it seems necessary.
7806 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
7808 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
7809 testing for __EMX__.
7811 * posix.c: #include <libc.h>, if it exists.
7813 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
7814 don't even know if the latter exists.
7816 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
7817 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
7818 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
7820 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
7822 (scm_init_posix): Use them when initializing the Scheme constants
7825 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7827 * Makefile.in (libdir, includedir, bindir): Use the
7828 autoconf-supplied values, instead of deriving them ourselves.
7829 (pkgincludedir, datadir, pkgdatadir): New variables.
7830 (install, uninstall): Put the header files in a special
7831 subdirectory, not in the main search path.
7833 * Makefile.in (ALL_CFLAGS): Provide the proper value for
7834 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
7836 * Makefile.in (IMPLPATH): Deleted; never used.
7838 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
7839 on the Tcl/Tk source any more.
7840 (INCLUDE_CFLAGS): Remove references to the above.
7842 * Makefile.in (version.o): Corrected dependencies.
7844 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
7846 * libguile.h: #include "version.h"
7848 * init.c (scm_boot_guile): Call scm_init_version.
7849 * gscm.c (gscm_run_scm): Call scm_init_version.
7851 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
7852 GUILE_VERSION): AC_DEFINE these.
7853 (acconfig.h): #undef the above symbols.
7855 * Makefile.in (libobjs): Add version.o.
7856 (installed_h_files): Add version.h.
7857 (c_files): Add version.c.
7858 (gen_c_files): Add version.x.
7859 (version.o): New rule.
7860 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
7861 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
7862 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
7863 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
7864 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
7865 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
7866 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
7867 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
7868 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
7869 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
7870 weaks.o): Add version.h to dependency lists.
7871 (markers.o): Remove duplicate rule.
7873 * version.h: New file.
7875 * version.c: New file.
7877 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7879 * symbols.c (scm_strhash): scm_downcase is now a function, not an
7880 array; use it appropriately. Since GCC is quite happy to
7881 subscript functions, it never warned us about this; we should use
7882 -Wpointer-arith in the future. I guess we never tested
7885 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
7887 * socket.c: Doc and copyright fixes.
7889 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7891 * debug.c: Fixed and improved gdb support.
7893 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7895 * socket.c: Added declaration of inet_aton to avoid compiler
7896 warning. (Hope this solution is correct.)
7898 * stime.c: Added declaration of ftime. (This is missing in
7901 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
7903 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
7905 * Makefile.in (c_files): add strerror.c.
7907 * strerror.c: new file from Emacs' sysdep.c.
7908 maybe configure should also check for sys_errlist.
7910 * configure.in (AC_REPLACE_FUNCS): add strerror.
7912 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7914 * debug.c (scm_init_debug): Added initialization for
7915 scm_evaluator_traps.
7917 * debug.h, debug.c: Various name changes.
7918 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
7919 "debug-options-interface". See commentary in options.c.
7921 * options.h, options.c: Options now have documentation strings.
7922 Also added a long explanatory commentary.
7924 * eval.c, print.h, print.c, read.h, read.c: Modifications to
7927 * gscm.c, init.c, root.c, throw.c: Bug fixes:
7928 last_debug_info_frame is now updated in all cases.
7930 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
7933 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7935 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
7936 Added option STACK_CHECKING.
7938 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7940 * Makefile.in: Added {debug,options,srcprop}.{h,c}
7942 * __scm.h: Removed symbols for debugging support.
7944 * acconfig.h: Added symbols for debugging support.
7946 * configure.in: Added user option for debugging support.
7947 --enable-debug will include the debugging code into libguile.a.
7949 * continuations.c (scm_make_cont): Enlarged the #if 0 around
7950 scm_relocate_chunk_to_heap.
7952 * debug.c: New file: low-level debugging support. It also
7953 includes support for debugging with gdb. (The extensions to gdb
7954 are written by Per Bothner at Cygnus.)
7956 * debug.h: New file: low-level debugging support.
7958 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
7959 argument pairs. Extensive modifications to the debugging
7960 evaluator. Added "SECTION:" commentaries to clarify what happens
7961 when, during double compilation. Renamed EVALIMP --> EVALIM.
7962 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
7963 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
7964 the beginning of the file. New procedure: scm_unmemocopy.
7965 Added some global state variables needed by the debugging
7966 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
7967 check_entry, check_apply, check_exit, debug_options and
7968 evaluator_traps. New acro: undefine.
7970 * eval.h: Renamed EVAL --> XEVAL.
7972 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
7973 --> scm_make_weak_key_hash_table.
7975 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
7976 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
7978 * libguile.h: Conditionally include debug.h
7980 * objprop.c (scm_object_properties, scm_set_object_properties_x):
7981 scm_object_properties shouldn't return handle. `handle' now gets
7982 initialized in scm_set_object_properties_x. scm_object_properties
7983 doesn't any longer create an entry in scm_object_whash.
7985 * options.c: New file: handling of run time options.
7987 * options.h: New file: handling of run time options.
7989 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
7991 * print.c: New procedure: scm_print_options
7993 * print.h: Defines for print options.
7995 * read.c: New procedure: scm_read_options
7997 * read.h: Defines for reader options.
7999 * root.h: Added scm_source_whash among scm_sys_protects.
8001 * srcprop.c: New file: source properties.
8003 * srcprop.h: New file: source properties.
8005 * throw.c (jbsmob): Jump buffers are now correctly allocated.
8006 (Bug found by A. Green.)
8008 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8010 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8012 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
8014 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8016 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8017 and should be called by the final client.
8019 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8021 * gc.h: Use the PROTO macro when declaring functions.
8022 * gc.c: Use the PROTO macro when declaring static functions.
8023 Remove the CPP hair around function definitions.
8025 * gc.c (scm_init_storage): Initialize scm_asyncs.
8027 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8028 preprocessor symbol; "__scm.h" is where it might get #defined.
8029 * __scm.h: Similar: #include <scmconfig.h> before testing
8032 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8034 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8036 * init.c (scm_boot_guile): Add init_func argument; call
8037 (*init_func) instead of calling scm_appinit; it's ucky to
8038 hard-code names for the user's procedures.
8039 * init.h (scm_boot_guile): Adjust declaration.
8041 * __scm.h (PROTO): New macro, for declaring functions with
8044 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8045 eliminate all the __STDC__ conditionals.
8046 (scm_boot_guile): Add declaration.
8047 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8048 Remove __STDC__ conditionals around function definitions; the
8049 declarations in init.h will provide the same information, more
8052 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8053 complain about it in the error message; the error message is
8054 adequate without that note, and there's nothing the user can do
8057 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8059 * Makefile.in (ancillary): Drop def.sed.
8061 * posix.c (scm_init_posix): Use numeric values, rather than
8062 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8063 F_OK. The symbols aren't available on some systems, and I'm
8064 pretty sure their values are fixed by common widespread practice.
8065 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8067 More functions unavailable on some systems.
8068 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8069 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8071 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8072 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8073 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8074 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8075 stub that signals an error as the #else.
8077 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8079 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8081 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8083 * unif.c: include ramap.h.
8085 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8087 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8089 * ports.c: include sys/ioctl.h.
8091 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8093 * configure.in: check for sys/ioctl.h.
8095 * ports.c: include <malloc.h> not "malloc.h".
8097 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8099 * fports.c: remove ttyname and tmpnam declarations.
8101 * posix.c: fewer ttyname declarations.
8103 * fports.c: include <string.h> not "string.h".
8105 * init.c, ioext.c: include string.h and unistd.h.
8107 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8109 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8110 genio.c, simpos.c, vports.c: include string.h.
8112 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8114 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8116 (scm_addr_buffer_size): change type from scm_sizet to int.
8117 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8118 from scm_sizet to int.
8120 * error.c: include unistd.h.
8122 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8125 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8127 * __scm.hd, def.sed: deleted.
8129 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8131 Changes for NeXT, suggested by Robert Brown.
8132 * configure.in: Call AC_TYPE_MODE_T.
8133 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8134 NeXT. Put header file list in alphabetical order.
8135 * configure, scmconfig.h.in: Regenerated.
8136 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8138 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8141 * acconfig.h: New file, providing documentation for the CPP
8142 symbols defined in configure.in
8143 * acconfig-1.5.h: Removed; superceded by the above.
8145 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8147 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8149 * fports.c (scm_open_file): don't return #f, throw error.
8151 * ioext.c (fileno): renamed from %fileno.
8152 (soft-fileno): deleted.
8154 * ports.c (scm_port_revealed): don't need to check for -1 from
8156 (scm_set_port_revealed_x): return unspecified, not #f.
8158 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8160 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8162 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8164 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8166 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8168 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8169 This is necessary on Ultrix, and doesn't hurt portability.
8171 * Makefile.in (dist-dir): New target, implementing a new dist system.
8172 (installed_h_files): Put in alphabetical order.
8173 Remove duplicate entries for markers.h and unif.h.
8174 (c_files): Remove duplicate entries for markers.c.
8175 (ancillary): Renamed from anillery; all uses changed. Remove
8176 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8177 Remove all the ../doc/* files; doc/Makefile.in handles that.
8179 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8181 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8182 every if must have an else, or else the whole command has a
8183 non-zero exit code whenever the if's condition is false.
8185 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8187 * posix.c: include string.h.
8189 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8191 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8194 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8195 Remove leading % from scheme names.
8196 Do not return error values, call SCM_SYSERROR or similar.
8198 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8200 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8202 * struct.c (scm_init_struct): new file.
8204 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8206 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8207 (scm_list_head): added list-head for rapidly chopping argument
8208 lists off of longer lists (and similar).
8210 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
8212 * objprop.c (scm_object_property): assq the cdr of the whash
8213 handle for obj, not the handle itself.
8215 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8217 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8218 weak hash tables last of all marking to avoid an obscure gc bug.
8219 WARNING: circular lists stored in a weak hash table will hose us.
8221 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8223 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8224 new functions similar to scm_substring_move_left_x and
8225 scm_substring_move_right_x.
8227 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8229 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
8232 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
8234 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8236 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8238 * strports.c (scm_strprint_obj): convenience function. C for
8239 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8241 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8242 removed to a separate library
8244 * init.c (scm_boot_guile): copied from guile-tcl.c.
8245 Initialization specific to tcl interpreters removed.
8247 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8249 * ports.c (scm_ports_prehistory): size malloced here doesn't
8250 matter so long as it is non-0 (got rid of "* 4").
8252 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8254 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8255 since its definition was bogus).
8257 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>

8261 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8263 * ports.c: removed functions relating to the mapping between ports

8272 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8273 handled correctly (SCM_FREEP was applied to them) -- test for

8329 * ports.c (scm_add_to_port_table): Added fields

8442 initialization to fix a race condition.
8444 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
