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

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

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

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

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

865 fports.h (scm_port): change size types from int to off_t.
866 ports.c (scm_init_ports): initialise the seek symbols here
867 instead of in ioext.c.
868 strports.c (scm_call_with_output_string): start with an empty
869 string, so seek and ftruncate can be used.
871 gdbint.c: adjust string port usage.
873 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
875 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
876 equivalent to fflush for the read buffer.
877 * ports.c (scm_newptob): set read_flush.
878 ports.c (void_port_ptob): set read_flush.
879 fports.c (local_read_flush): new proc. add to ptob.
880 strport.c (st_read_flush): likewise.

883 left but fdes. leaving it as a struct to allow for future changes.
884 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
885 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
886 ptob proc if the read buffer is filled.
888 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
890 * ports.h (scm_port): add a rw_random member and replace
891 reading and writing members with rw_active member.
892 SCM_PORT_READ/SCM_PORT_WRITE: new values.
894 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
896 * ports.h (struct scm_port_table): add writing and reading members
897 to replace write_needs_seek: it isn't good enough for non-fports.
898 ports.c, ioext.c, fports.c: corresponding changes.
899 (struct scm_port_table): give it a typedef and rename to scm_port.
900 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
901 corresponding changes.

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

999 * ports.h (scm_ptobfuns): add seek function pointer.
1000 * fports.c: set it to local_seek, new procedure.
1003 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
1004 use ptob for seek. take ptob instead of fport arg.
1006 * ports.h (struct scm_port_table): new member write_needs_seek,
1007 replaces reading member in fport struct.
1009 * vports.c (sfgetc): store the getted char into the buffer.
1010 rename to sf_fill_buffer and install it for fill-buffer in ptob.
1011 the Scheme interface is still a procedure that gets a char.
1012 (scm_make_soft_port): set up the port buffer (shortbuf).
1014 * fports.c (local_fgetc, local_fgets): deleted.
1015 * strports.c (stgetc): likewise.
1016 * ports.c: scm_generic_fgets: likewise.
1018 * ports.h (scm_ptobfuns): add fill_buffer.
1019 * ports.c (scm_newptob): assign it.
1020 * strports.c (scm_mkstrport): set up the buffer.
1021 put just the string into the stream, not cons (pos stream).
1022 (stfill_buffer): new proc.
1024 * ports.h: fport buffer moved into port table: to be
1025 used for all port types.
1027 1998-12-20 Gary Houston <ghouston@easynet.co.uk>
1029 * throw.c (scm_handle_by_message): flush ports at exit.

1034 scm_getpeername, scm_recv, scm_send, scm_recvfrom,
1036 use SCM_FPORT_FDES. use SCM_OPFPORTP not SCM_FPORTP.
1038 * posix.c (scm_getgroups): use SCM_ALLOW/DEFER_INTS.
1039 (scm_ttyname): use SCM_FPORT_FDES.
1040 (scm_tcgetpgrp, scm_tcsetpgrp): likewise.
1042 * filesys.c (scm_chown): use SCM_FPORT_FDES.
1043 (scm_chmod, scm_stat, scm_truncate_file: likewise.
1045 * ioext.c (scm_isatty_p): use SCM_FPORT_FDES.
1046 (scm_fdes_to_ports): modified.
1047 (scm_fdopen): use scm_fdes_to_port.
1049 * ports.c (scm_init_ports): don't try to flush ports using
1050 atexit(). it's too late, errors will cause SEGV.
1052 * fports.c (scm_fport_buffer_add): new procedure.
1054 * fports.h (SCM_FDES_RANDOM_P): new macro. use it in
1055 scm_fdes_to_port and scm_redirect_port.

1220 * strop.c (scm_string_capitalize_x): Use the SCM object `s' in
1221 error messages, not the uninitialized string `str'. Love that
1224 * strop.c (scm_substring_move_x): New function, which can handle
1225 arbitrary overlapping substrings.
1226 (substring-move-left!, substring-move-right!): These are

1300 1999-03-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1302 * numbers.c (isfinite): Define this macro if not defined: Return a
1303 non-zero value if X is finite. (From ISO C 9x standard.)

1356 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1358 Most of this batch of changes is about how to deal with extended
1359 types when an object system is loaded into Guile. A nice object
1360 system is capable of representing Guile's types as class objects.
1362 For example, we want a regular expression to be of class <regex>.
1363 But regular expressions are smobs which aren't under direct
1364 control of the object system, so there has to be some mechanism
1365 which informs the object system that a new class should be created
1366 which can represent the smob type. I call this a "wrapper class".
1368 * objects.c: #include "smob.h";
1369 (scm_class_keyword): Removed. (Class is automatically created by
1371 (scm_smob_class): Array of smob classes indexed by smobnum.
1372 (scm_make_extended_class): "Plugin" function pointer for creation
1373 of wrapper classes for smob and struct types.
1374 (scm_class_of): Handle compiled closures. (Currently regarded as
1376 Use scm_smob_class to handle smob types;
1377 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1378 through scm_smob_class;
1381 * smob.c (scm_newsmob): Also create a wrapper class if
1382 scm_smob_class has been initialized.
1384 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1385 type code and smobnum.
1387 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1388 (scm_struct_table): Weak key table with auxilliary information for
1389 struct types. Currently used for names and wrapper classes.
1390 (scm_struct_ihashq): Hash function for structs.
1391 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1392 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1393 for accessing names of vtables. The record implementation in
1394 boot-9.scm currently uses the setter to record the name of record
1395 types. When the object system is initialized, it can use this
1396 information to create wrapper classes with suitable names.
1397 (scm_init_struct): Allocate scm_struct_table.
1398 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1399 (struct tags are a finite resource and we might want to restrict
1400 the use of tags to vtables only. E.g., Goops only uses tags for
1402 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1404 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1407 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1408 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1409 Used for access of struct table entries.
1411 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1412 (scm_hash_fold): New procedure. Used to process all entries in a
1413 hash table (in no particular order).
1415 Argh! For the umpteenth time I got compilation errors because of
1416 the "intuitive" name `kw'. This has to have an end:
1418 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1419 "kw" --> "keywords" everywhere.
1420 (I doubt that this will cause big compatibility problems since the
1421 application interface is unaffected.)
1423 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1425 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1427 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1428 column inums to native form.
1430 Improvement of backtraces: Introduces a new stack narrowing
1431 specifier, #t, for the inner cut. (See further in the comments in

1435 (Used to flag certain system procedures which shouldn't turn up in
1438 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1439 modules which aren't "user" modules and the code of which

1443 Extract the lookup closure from an environment.
1444 (scm_system_module_env_p): New function: Return non-#f if MODULE

1450 * debug.c (scm_procedure_name): Use name property in the default
1453 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
1455 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1457 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1458 procedure throughout.
1460 * print.c (scm_iprin1): Removed extraneous space when printing
1461 procedure-with-setters.
1463 Entity and operator setter slots were introduced as a complement
1464 to the <procedure-with-setter> type in order to support entities
1465 and operators with setters in a reasonable and efficient way.
1466 * procs.c (scm_procedure, scm_setter): Handle entity and operator
1469 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

1482 directly through the instance.
1484 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1486 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1487 scm_struct_i_flags instead of scm_vtable_index_layout!
1489 * list.c (scm_list_star): New procedure.
1491 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1521 (scm_init_readline): Call init_bouncing_parens.

1557 scm_symbol_value0), unif.c (scm_aind, scm_shap2ra): Argument
1558 indicating calling subr, error message text, reason for error,
1559 symbol name or feature name are now pointer to const.
1560 * snarf.h (SCM_PROC, SCM_PROC1): String variables are now const.
1562 * procs.c (scm_init_iprocs): iproc argument now points to const.
1563 * pairs.c (cxrs): Now const.
1565 * chars.h, error.h, feature.h, filesys.h, gc.h, gsubr.h, macros.h,
1566 numbers.h, options.h, procs.h, ramap.h, read.h, smob.h,
1567 strports.h, symbols.h, unif.h: Update variable declarations and
1568 function prototypes for above changes.

1571 sysdep_dynl_unlink, sysdep_dynl_func): Arguments FNAME, SUBR, and
1572 SYMB now point to const.
1574 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1576 * print.c (scm_iprin1): Use scm_procedure_name instead of
1577 scm_procedure_property for compiled closures.
1579 * tags.h (scm_tc7_pws): New procedure type. Four representations
1580 for procedure-with-setters were considered before selecting this
1583 1. A closure where the CODE and ENV slots are used to represent
1584 the getter and a new SETTER slot is used for the setter. The
1585 original getter is stored as a `getter' procedure property. For
1586 closure getters, the CODE and ENV slots contains a copy of the
1587 getter's CODE and ENV slots. For subr getters, the CODE contains
1590 2. A compiled closure with a call to the getter in the cclo
1591 procedure. The getter and setter are stored in slots 1 and 2.
1593 3. An entity (i.e. a struct with an associated procedure) with a
1594 call to the getter in the entity procedure and the setter stored
1595 in slot 0. The original getter is stored in slot 1.
1597 4. A new primitive procedure type supported in the evaluator. The
1598 getter and setter are stored in a GETTER and SETTER slot. A call
1599 to this procedure type results in a retrieval of the getter and a
1600 jump back to the correct eval dispatcher.
1602 Representation 4 was selected because of efficiency and
1605 Rep 1 has the advantage that there is zero penalty for closure
1606 getters, but primitive getters will get considerable overhead
1607 because the procedure-with-getter will be a closure which calls
1610 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1611 <procedure-with-setter>, but together with rep 2 it suffers from a
1612 three level dispatch for non-GOOPS getters:
1614 cclo/struct --> dispatch proc --> getter
1616 This is because the dispatch procedure must take an extra initial
1617 argument (cclo for rep 2, struct for rep 3).
1619 Rep 4 has the single disadvantage that it uses up one tc7 type
1620 code, but the plan for uniform vectors will very likely free tc7
1621 codes, so this is probably no big problem. Also note that the
1622 GETTER and SETTER slots can live directly on the heap, using the
1623 new four-word cells.
1625 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,
1626 SCM_SETTER): New macros.
1627 (scm_procedure_with_setter_p, scm_make_procedure_with_setter,

1652 * eval.h: Declare scm_s_set_x, scm_sym_set_x;
1654 * eval.c: Renamed "set" --> "set_x" in various names for
1655 consistency of name correspondence between Scheme and C;
1656 Renamed scm_i_set_x --> scm_sym_set_x and made global.
1657 Renamed s_set_x --> scm_s_set_x and made global.
1659 1999-01-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1661 * random.c (scm_i_random_bignum): Made independent of endianness.

1679 scm_rstate from seed.
1680 (scm_copy_random_state, scm_seed_to_random_state): New functions.
1681 (scm_make_random_state): Removed.
1683 * random.c (scm_make_random_state): Use scm_i_make_rstate().

1687 * random.c: Bugfix: Retrieve and store most significant 32 bits in
1688 different order if the machine is bigendian.

1694 from first arg before equal elements in second arg in result.
1695 (scm_merge_list_step): Bugfix: Don't presume that arguments in a C
1696 function call are executed in a well defined order.
1698 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
1700 * alloca.c (alloca): Cast value returned by malloc. (Thanks to
1703 1999-01-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1705 * random.c: Removed alloca includes.
1707 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
1709 * Makefile.in: This changed, for some reason I don't really
1710 understand, when I ran automake in the top level directory. This
1711 may be contamination by Cygnus internal releases. If you re-run
1712 automake and this change gets reverted, don't worry about it.
1714 1999-01-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1716 * sort.c, sort.h: New files: Implement slib's and scsh's sort
1717 interfaces. Author: Roland Orre.

1727 Renamed s_bignum --> scm_s_bignum.
1729 * random.c, random.h: New files: Random number support.
1730 Interface same as slib's.
1732 * Makefile.am: Added random.c, random.h, random.x.
1734 * init.c: #include "random.h";
1735 (scm_boot_guile_1): Call scm_init_random ().
1737 1998-12-23 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1739 * Makefile.am: New files: guardians.c, guardians.x, guardians.h
1741 * guardians.c, guardians.h (scm_make_guardian,
1742 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
1743 scm_get_one_zombie, scm_init_guardian): This is an implementation
1744 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
1745 David Eby (1993) "Guardians in a Generation-Based Garbage
1746 Collector" ACM SIGPLAN Conference on Programming Language Design
1747 and Implementation, June 1993 ftp://ftp.cs.indiana.edu
1748 /pub/scheme-repository/doc/pubs/guardians.ps.gz
1749 Author: Michael N. Livshin.
1751 * gc.h (SCM_MARKEDP, SCM_NMARKEDP): New macros.
1753 * gc.c (scm_igc): Call scm_guardian_gc_init and
1754 scm_guardian_zombify.

1758 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1760 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
1763 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1765 Move the procedure slots of entities to invisible slots (so that
1766 we can have operator class objects which themselves are entities).
1767 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
1768 SCM_STRUCTF_ENTITY): New constants.
1770 * struct.c (scm_make_struct): Allocate "invisible" room for
1771 procedures if SCM_STRUCTF_ENTITY is set in vtable.
1773 * gc.c (scm_gc_mark): Mark entity procedures.
1775 * struct.c, struct.h (scm_alloc_struct): Renamed from alloc_struct
1777 (scm_struct_init): Renamed from init_struct and made global.

1780 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
1781 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
1783 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
1785 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
1786 of syntactic forms, similar to SCM_PROC.
1787 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
1788 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
1789 for the name symbols when needed.
1791 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
1793 * Makefile.in: Regenerated.
1795 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
1797 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
1798 take the address of _into; it might be a register. Just have
1799 scm_debug_newcell return the new cell.
1800 * gc.c (scm_debug_newcell): Just return the new cell, instead of
1801 taking the address of a place to store it as an argument.
1802 * gc.h (scm_debug_newcell): Change declaration.
1803 (Thanks to Greg Harvey.)
1805 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1807 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
1808 Replaces old names serial-array-copy! and serial-array-map!.

1814 * smob.c (freeprint): New function.
1815 (freecell): Use it to print freed objects, for slightly easier
1818 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1820 * backtrace.c (display_frame): Made more robust. Doesn't throw an
1821 error if no source properties can be found for a frame. (Thanks
1822 to Christian Lynbech.)
1824 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1826 * objects.h: Removed slots direct_supers and direct_slots from the
1827 definitions of the rudimentary classes described by objects.h.
1829 * objects.c, objects.h (scm_entity_p): New procedure. Together
1830 with the predicates scm_procedure_p and scm_struct_p, this
1831 predicate makes it possible to differ between structs, entities
1834 * modules.c, modules.h (scm_resolve_module): New function.
1836 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1838 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
1839 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
1842 * objects.c (scm_entity_p): New procedure.
1844 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
1845 for asubrs, rpsubrs, lsubrs and lsubr_2s.
1847 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1849 * procprop.h (scm_i_procedure_arity): Added declaration.
1851 * procprop.c (scm_i_procedure_arity): Made global; New code to
1852 handle operators and entities.
1853 (scm_procedure_property): No need to call scm_procedure_p since
1854 scm_i_procedure_arity now does all necessary type checking.
1855 Added #include "objects.h".
1857 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
1858 s_add_hook_x --> s_remove_hook_x.
1859 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
1860 Added #include "procprop.h"
1862 * feature.c, feature.h (scm_reset_hook_x): New procedure.
1863 (scm_make_hook): Optional argument defines number of arguments to
1865 (scm_make_named_hook): Take number of args as second arg.
1866 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
1867 boot-9.scm for a while); First arg is the hook. The rest are
1868 arguments passed on to the hook procedures.
1870 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
1872 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
1873 scm_logbit_p): Do the computation in ulongs. This is not as nice
1874 as doing it in bignums, but at least it's good enough for
1875 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
1877 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
1878 subexpressions. (Thanks to Charbel Jacquin.)
1880 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
1882 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
1883 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
1884 (scm_make_named_hook): New function.
1886 * feature.c: Added #include "eval.h".
1888 * modules.c (scm_make_module): Beautify the module.
1890 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1892 * modules.c, modules.h: New files: C interface to modules. (This
1893 is necessary in order to interface the object system to Guile
1894 properly. The guts of these modules will be replaced by the new
1895 module system in the future.)
1897 * init.c: Added #include "modules.h"
1898 (scm_boot_guile_1): Call scm_init_modules.
1899 (invoke_main_func): Call scm_post_boot_init_modules.
1901 * Makefile.am: Added modules.c, modules.x, modules.h.
1903 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
1905 * procs.c: #include "objects.h"
1906 (scm_procedure_p): Return #t also on structs which are operators.
1908 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
1909 <operator-metaclass> and <entity-class> to <standard-class>,
1910 <operator-class> and <entity> in order to conform with STKlos
1913 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
1914 which isn't an operator.
1915 (SCM_APPLY): Ditto, but jump to badproc.
1917 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
1919 * eval.c (SCM_CEVAL): Allow structs implanted in code.
1920 Previously, structs implanted in code were interpreted as forms
1921 the operator of which was a gloc. We solve this by checking for
1922 the zero in the emulated vcell in the struct vtable. Since
1923 implanted structs always will look like forms with a gloc
1924 operator, execution will only be slowed down by maximally one
1925 extra test-and-branch per application.
1927 * evalext.c (scm_definedp): Removed check for isyms; Added a
1928 second optional argument: It is now possible to supply an
1929 evaluation environment in which to look for the symbol.
1931 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1933 * readline.c (scm_init_readline): Set
1934 rl_basic_word_break_characters. (Thanks to Ian Grant.)
1936 * coop.c (coop_condition_variable_wait): Removed
1937 (coop_condition_variable_wait_mutex): Folded logic of
1938 coop_mutex_unlock into coop_condition_variable_wait_mutex to
1939 prevent condvar signal lossage. Previously, another thread could
1940 start to run after unlocking the mutex but before putting the
1941 current thread on the wait queue. If that thread then would
1942 signal the first, the signal would be lost. (Thanks to Christian
1945 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1947 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
1950 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1952 * objects.c (scm_i_make_class_object): Renamed from
1953 make_class_object; exported; error checking moved to
1954 scm_make_class_object and scm_make_subclass_object.
1955 (scm_make_class_object, scm_make_subclass_object): Use
1956 scm_i_make_class_object.
1957 (scm_make_subclass_object): Let the subclass have same metaclass
1960 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1962 * debug.c (scm_debug_options): Bugfix: Set the value of
1963 scm_stack_checking_enabled_p after setting debug options;
1964 #include "stackchk.h". (Thanks to Richard Polton.)
1966 1998-11-13 Radey Shouman <rshouman@metro2000.com>
1968 * unif.c (scm_array_contents): removed unnecessary test for 0
1971 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1973 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
1974 Replaced by macro `collect' in boot-9.scm.
1976 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1978 * eval.c (scm_copy_tree): Copy source properties if existent.
1980 * debug.c (scm_start_stack): Copy source when evaluating. (If we
1981 don't, we may end up passing memoized source to a transformer.)
1983 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1985 * stack.c (get_applybody): Help function which lookups the first
1986 body form of the apply closure.
1987 (read_frames): Prevent the source of the first form of the apply
1988 closure from being recorded. This would only be confusing.
1990 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
1991 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
1993 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
1995 * stacks.c (read_frame): Bugfix: Removed lingering `else'
1997 (read_frames): Use SCM_MACROEXPP.
1999 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2001 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
2002 don't contain interesting information since all arguments are
2003 present in the frame which applies the compiled closure anyway.);
2004 Skip the transformer application frames.
2006 * print.c (scm_iprin1): Print gsubrs as primitives.
2008 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2010 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
2012 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
2013 that we can identify these in a backtrace. (This change doesn't
2014 introduce any significant speed penalty.)
2016 * eval.c: Added note about `serial-map' using scm_map.
2018 * read.c, read.h (scm_read_options, scm_read_opts): Removed
2019 readline options. They should reside in their own options array.
2021 * readline.c, readline.h (scm_readline_options,
2022 scm_readline_opts): Moved readline options here.
2024 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2026 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2027 SCM_ROCHARS instead of SCM_CHARS.
2029 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2030 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2032 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2034 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2035 This is quite important since the latter clears the
2036 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2037 every single character read...
2039 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2041 * print.c (scm_iprin1): Removed suspect looking (and indeed
2042 malevolent) semicolon after test for user supplied closure print
2043 procedure. (Thanks to Telford Tendys.)
2045 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2046 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2047 starting to search the list. Removed call to sloppy_mem_check.
2049 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2050 procedures: Same as scm_delq_x et al, but delete maximally one
2053 * options.c (scm_options, scm_init_options): GC-protect option
2054 values of type SCM. (Thanks to Telford Tendys.)
2056 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2058 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2059 make sure that there always is a "real" scm_lookupcar.
2061 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2063 * read.c, read.h (scm_read_opts): New read options
2064 "history-length" and "history-file".
2065 (scm_read_options): Stifle history to history length.
2067 * readline.c (scm_read_history, scm_write_history): New procedures.
2069 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2071 * eval.h (scm_macro_eval_x): Removed declaration.
2073 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2074 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2075 Renamed and made global.
2077 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2078 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2080 * evalext.c, evalext.h: New files. Contain non-R5RS things
2081 having to do with evaluation.
2083 * evalext.c (scm_serial_map): New procedure: Version of `map'
2084 which guarantees that the procedure is applied to the lists in
2086 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2087 returns a list of the results of the body forms instead of the
2088 result of the last body form.
2089 (scm_definedp, scm_m_undefine): Moved from eval.c
2091 * evalext.h (scm_m_sequence_to_list): Added declaration.
2093 * macros.c, macros.h: New files.
2094 (scm_procedure_to_syntax, scm_procedure_to_macro,
2095 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2096 scm_macro_name, scm_macro_transformer): Moved from eval.c
2097 (scm_make_synt): Moved from eval.c
2099 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2101 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2104 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2106 * debug.c, print.c: Added #include "macros.h".
2108 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2110 This change adds the ability to use `unread-char' multiple times
2111 without interspersed reads and adds the new procedure
2112 `unread-string'. The change is optimized for the common case of
2113 unreading a single character. This is also the reason behind the
2114 choice to store characters in the port itself: in most cases no
2115 extra malloc is required.
2117 The amount of code in some macros in ports.h has been increased to
2118 the extent that they would fit better as C functions, but, since
2119 this code belongs to the port representation, such functions
2120 should be placed in ports.c which would cause calls back and forth
2121 between ports.c and genio.c. That is not good for performance.
2122 Also, keeping them as macros allows the compiler to do some
2123 optimizations which are needed to make the current interface
2124 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2126 One benchmark (Guile startup time) indicates an increase of
2127 loading speed of 1%. Another (reading (using `read') boot-9.scm
2128 10 times) shows no change in performance.
2130 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2131 made to find a beautiful solution.)
2133 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2134 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2135 character. (SCM_CLRDY clears all.)
2136 (SCM_N_READY_CHARS): New macro: Returns number of unread
2137 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2138 (struct scm_port_table): New fields: `entry' contains port table
2139 index, `cp' points to last unread char, `cbuf' is the buffer for
2140 unread chars, `cbufend' points after end of the character buffer.
2142 * ports.h, ports.c (scm_unread_string): New procedure.
2143 (scm_grow_port_cbuf): New function.
2145 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2147 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2148 to read unread characters. Use SCM_TRY_CLRDY instead of
2151 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2153 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2155 * genio.c, genio.h (scm_ungets): New function.
2157 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2160 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2162 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2163 declarations. (Thanks to Russ McManus.)
2165 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2167 * numbers.c (num2long): As a software archeologist, I'm proud of
2168 this finding! :) Preliminary dating suggests an almost 4 year old
2169 remnant from the SCM ancestor. The sample has been removed from
2170 the finding site and is now safely stored in the repository.
2172 * numbers.h: Removed prototype for num2long.
2174 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2176 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2177 array as second arg.
2178 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2179 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2180 * gh.h: Updated and added prototypes.
2182 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2184 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2186 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2188 * guile-snarf.in: Never generate an empty file. (Thanks to
2191 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2192 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2193 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2194 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2195 gh_new_procedure5_0): Specify argument types, to appease C++
2196 compilers. (Thanks to Brad Bowman.)
2198 Bug reports from Russ McManus:
2199 * guile-snarf.in: If the CPP environment variable is set, use that
2200 as the C preprocessor, instead of the preprocessor autoconf
2202 * snarf.h (SCM_PROC): Cast the function pointer passed to
2203 scm_make_gsubr, to satisfy C++.
2205 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2206 Use the handler passed, instead of ignoring it and using
2207 gh_standard_handler. (Thanks to Etienne Bernard.)
2209 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2211 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2214 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>

2231 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
2234 * script.c (scm_compile_shell_switches): Define
2235 use-emacs-interface in the root module, so the repl code can see
2236 it. See today's change to top-repl in ice-9/boot-9.scm.
2238 * filesys.c (set_element, get_element): Make sure that `element'
2239 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2240 Boekemeier and Jorgen "forcer" Schaefer.)
2242 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2244 * chars.c (scm_charnames): In ASCII character name table, make
2245 newlines print as #\newline by default, not #\nl.
2247 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2248 alphabetical order. Oh thrills. But it helps me know how far
2249 along in the compilation I am.
2250 * Makefile.in: Regenerated.
2252 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2254 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2255 #bytes(...) to #y(...), and syntax for short vectors from
2256 #short(...) to #h(...). This may seem nutty, but, like the other
2257 uniform vectors, byte vectors and short vectors want to have the
2258 same print and read syntax (and, more basic, want to have read
2259 syntax!). Changing the read syntax to use multiple characters
2260 after the hash sign breaks with the conventions used in R5RS and
2261 the conventions used for the other uniform vectors. It also
2262 introduces complexity in the current reader, both on the C and
2263 Scheme levels. (The Right solution is probably to change the
2264 syntax and prototypes for uniform vectors entirely.)
2266 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2268 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2269 (Thanks to Jorgen "forcer" Schaefer.)
2270 * ports.h (SCM_NOFTELL): New flag.
2271 * fports.c (local_fgets): If it's set, use the generic fgets.
2272 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2274 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2276 * script.c (scm_compile_shell_switches): Add handling of -q switch
2277 (inhibit loading of user init file).
2278 (scm_shell_usage): Add usage text for -q switch.
2279 (scm_compile_shell_switches): Always load user init file first if
2280 it is loaded at all.
2282 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2284 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2285 and is now broken under NetBSD. I can't fathom what it's trying
2286 to do, so I've replaced it with something that I do understand,
2287 which seems to work, and which isn't broken on NetBSD. "Progress?
2288 You Decide." (Thanks to Perry Metzger.)
2290 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2291 signed/unsigned comparison.
2293 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2295 Warning fixes from Greg Harvey:
2296 * unif.c (scm_array_set_x): initializer for pos
2297 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2298 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2299 initializers for field_type, since EGCS so desparately wants to
2301 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2302 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2303 when GUILE_DEBUG is defined.
2304 * dynwind.h (scm_wind_chain): Same.
2305 * ports.h (scm_pt_size, scm_pt_member): Same.
2306 * print.h (scm_current_pstate): Same.
2307 * procs.h (scm_make_cclo): Same.
2309 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2311 Handle short and long long uniform arrays properly. (Thanks to
2313 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2314 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2315 scm_tc7_llvect (long long vectors).
2317 Change the way libguile and boot-9.scm are timestamped, to try to
2318 get rid of these spurious mismatch warnings. Now both
2319 libguile/versiondat.h and ice-9/version.scm are generated directly
2320 by the configuration process, rather than having version.scm
2321 generated directly, and libguile/versiondat.h generated by the
2322 Makefile, which is generated by configure. It seems that
2323 sometimes the Makefile would change, but versiondat.h depends on
2324 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2325 * Makefile.am (versiondat.h): Target removed; this is generated
2326 directly by the configure script now.
2327 (BUILT_SOURCES): Remove versiondat.h.
2328 * versiondat.h.in: New file, transformed by the configure script
2330 * Makefile.in: Regenerated.
2332 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2333 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2334 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2335 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2336 if we want to use them in a header file some day, we can. (Thanks
2337 to Michael Livshin.)
2339 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2340 SCM numbers, so we won't have rollover problems; the range of a
2341 signed long in milliseconds is about 25 days. (Thanks to Karl
2344 Don't redefine sleep and usleep; fix this problem now.
2345 * coop.c (sleep, usleep): Remove declarations; we don't use or
2346 redefine these any more.
2347 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2348 job of usleep and sleep in a thread-friendly way. We can use
2349 these in the rest of Guile. Define versions for systems both with
2350 and without iselect.
2351 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2352 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2353 we're just using it, not redefining it, we can use a K&R style
2355 (sleep): Declare this, too, if the system hasn't.
2356 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2357 scm_uthread_sleep if they're available; otherwise, just call the
2359 * scmconfig.h.in: Regenerated.
2361 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2363 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2365 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2367 * threads.c: Doc fix.
2369 The argument type of usleep varies from system to system,
2370 as does the return type. We really shouldn't be redefining usleep
2371 at all, but I don't have time to clean that up before the 1.3.
2372 release. It's on the schedule for afterwards. (Thanks to Julian
2374 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2376 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2377 * scmconfig.h: Regenerated.
2379 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2380 right way to handle system variation. Autoconf's approach is the
2382 * simpos.h (scm_software_type): Declaration deleted.
2384 * script.c (scm_find_executable): Don't test if unix is #defined
2385 here; first, NetBSD doesn't #define it, and second, it's the wrong
2386 way to go about these things. (Thanks to Perry Metzger.)
2387 (dld_find_executable): Delete this MSDOS support code. This isn't
2388 the way we want to support this; it needs to be rethunk at a
2391 * genio.c (scm_do_read_line): Don't just politely check that the
2392 line was either non-empty or EOF. Abort if it's empty and not
2395 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2397 * scmconfig.h.in: Regenerated.
2399 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2402 * genio.c (scm_do_read_line): Count lines correctly when the file
2403 doesn't end in a newline.
2405 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2407 * genio.c (scm_do_read_line): Maintain the line count correctly.
2408 (Thanks to Harvey J. Stein and Greg Harvey.)
2410 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2413 * numbers.c (big2str): Protect t from garbage collection until
2414 we're done. (Thanks to Gary Houston.)
2416 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2418 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2420 * Makefile.in: Regenerated.
2422 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2423 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2426 Do magic to mix reads and writes on stdio FILE-based ports.
2427 (Thanks to Christian Lynbech.)
2428 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2430 (pre_read, pre_write): New functions.
2431 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2432 local_fputs): Call them.
2433 (local_fflush): Mark the port as ready for reading and writing.
2434 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2435 flags on new port objects. This might not be accurate --- who
2436 knows what state the FILE * is in when we get it --- but it won't
2437 do extraneous calls to fflush or fseek, so it's no worse than the
2438 behavior before this change.
2439 * ports.h: Add comment.
2441 Centralize the creation of port objects based on stdio FILE * in
2442 fports.c; don't just throw them together anywhere.
2443 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2444 what the rest of Guile wants. Don't set the revealed count;
2445 that's only appropriate for stdin, stdout, stderr.
2446 (scm_standard_stream_to_port): This function does set the revealed
2448 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2449 not scm_stdio_to_port.
2450 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2451 * fports.c (scm_open_file): Same.
2452 * posix.c (scm_pipe): Same.
2453 * socket.c (scm_sock_fd_to_port): Same.
2454 * ioext.c (scm_fdopen): Same.
2455 (scm_freopen): Moved from here to...
2456 * fports.c (scm_freopen): ... here. This is really something that
2457 munges the internals of an fport, so it should go here.
2458 * fports.h (scm_stdio_to_port): Adjust prototype.
2459 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2460 * ioext.h (scm_freopen): Prototype removed.
2462 * filesys.c (set_element, get_element): This can work on both pipe
2463 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2466 * scmconfig.h.in: Regenerated.
2468 Change the definition of the functions in scm_ptobfuns so that
2469 they get passed the port object, not the port's stream.
2470 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2471 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2472 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2473 Pass the port itself to the scm_ptobs function.
2474 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2475 scm_generic_fgets): Same.
2476 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2477 getc_void_port, fgets_void_port, close_void_port): Just change the
2478 argument names; these functions don't really do anything.
2479 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2480 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2481 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2482 Also, use prototyped definitions, and get rid of the extra
2484 (scm_fptob, scm_pipob): We don't need casts here any more.
2485 * strports.c (prinstpt): Use prototype declarations.
2486 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2487 and use SCM_STREAM to get the string info. Also, use prototyped
2488 definitions, and get rid of the extra declarations.
2489 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2492 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2493 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2495 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2496 scm_fgets, for consistency.
2497 (scm_fptop, scm_pipob): References updated.
2499 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2501 Include the source location in error messages for scripts.
2502 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2503 stack is still there when we catch the error.
2504 * throw.c (handler_message): If we are handling an error with a
2505 message, then put together the proper arguments and call
2506 scm_display_error, instead of scm_display_error_message. That
2507 displays source location, if it can find it.
2509 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2511 * gc.c (scm_unprotect_object): Change this so that calls to
2512 scm_protect_object and scm_unprotect_object nest properly.
2513 (scm_protect_object): Doc fixes.
2515 * strings.c (scm_string_set_x): Require the argument to be a
2516 writable string, not a substring or a symbol.
2517 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2518 (Thanks to John Redford and Charbel Jacquin.)
2520 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2522 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2524 * eval.c (safe_setjmp): Remove this misunderstanding.
2525 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2528 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2530 * libguile.h: Mark these as C declarations, for compilation by C++
2533 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2534 __cplusplus clause. I seriously doubt this ever worked the way
2535 the author seems to have intended.
2537 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2539 Utterly needless cleanups to hopelessly messy code.
2540 * ports.c: Doc fixes.
2541 (scm_fflush): Moved to ...
2542 * genio.c (scm_fflush): ... here, amongst all the other port
2543 method invocation functions.
2544 * genio.h, ports.h: The prototype moves too.
2546 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2548 * backtrace.c (display_error_body): The current frame does not
2549 always have a parent frame; consider a function called directly
2550 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2553 * alloca.c (alloca): Undo yesterday's changes, and simply call
2554 malloc directly for storage, and abort if we don't get what we
2555 want. The situation is much simpler --- just call malloc. Emacs
2556 has bizarre/evil requirements (signal handlers might malloc unless
2557 you set this global flag, so you have to set the flag around all
2558 calls to malloc) which we are certainly not going to conform to,
2559 so we can do the simple and obvious thing.
2561 * coop.c (coop_condition_variable_wait): Make this function
2562 static. It's only useful internally --- you should never just
2563 wait on a condition variable.
2564 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2566 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2568 * unif.c (scm_array_set_x): Accept any kind of number as an
2569 element for a uniform vector of doubles. This is more consistent
2570 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2572 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2573 works; I can't conveniently test it myself. (Thanks to Dvid
2574 Tillman for the bug report.)
2576 * init.c: Doc fixes.
2578 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2579 from here, not from scm_compile_shell_switches (which is a pretty
2580 dumb place to do it).
2581 (scm_load_startup_files): New function.
2582 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2583 * script.c (scm_compile_shell_switches): Don't load the startup
2585 (scm_ice_9_already_loaded): Variable moved.
2586 * init.c (scm_load_startup_files): Prototype for new function.
2587 * gh_init.c (gh_enter): Doc fix.
2589 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2591 Some anti-warning changes from Greg Harvey.
2592 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2593 warnings when it doesn't understand our NORETURN declarations in
2595 * posix.c (scm_mknod): Similar.
2597 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2599 * posix.c (scm_getpwuid): If we can't find an entry, return our
2600 own message, instead of using scm_syserror --- the getpwMUMBLE
2601 functions don't set `errno' to anything interesting.
2603 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2605 Get rid of warnings from the cooperative threading system.
2606 * threads.h (scm_single_thread_p, scm_yield,
2607 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2608 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2609 scm_wait_condition_variable, scm_signal_condition_variable): Add
2610 prototypes for these Scheme-visible functions.
2611 * coop-defs.h (coop_next_runnable_thread,
2612 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2613 Prototypes for these here, even though they're from iselect.c.
2614 (coop_condition_variable_wait, coop_join): Add prototypes.
2615 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2616 scm_threads_free_condvar): Make these smob functions static.
2617 * coop-threads.h (coop_init): Give this a real prototype.
2618 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2619 (coop_next_runnable_thread): No need to provide prototype; it's in
2622 * scmconfig.h.in: .detarenegeR
2624 * iselect.c, threads.c: Doc fixes.
2626 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2628 * Makefile.in: Regenerated with a patched automake, to get
2629 dependency generation right when using EGCS.
2631 * inet_aton.c (inet_aton): Add prototype, to remove compiler
2632 warning. (Thanks to Robert Pluim.)
2634 * inet_aton.c (inet_aton): Reassure the compiler that the
2635 arguments to the <ctype.h> macros are all unsigned characters, not
2638 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2640 Getting rid of more warnings...
2641 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
2642 today's change to ../configure.in.
2643 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
2644 * scmconfig.h.in: Regenertaded.de.,.__
2645 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
2646 (scm_localtime, scm_mktime): Use a const char * to manipulate the
2649 * readline.c: Doc fix.
2650 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
2651 * readline.h (scm_filename_completion_function): Add prototype.
2652 (scm_init_readline): Make this into a prototype.
2654 * readline.c (scm_filename_completion_function): Use SCM_PROC to
2655 declare this, instead of calling scm_make_subr manually.
2657 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
2659 * readline.h (scm_init_readline): Add prototype for this.
2660 (scm_init_readline): Make this a real prototype.
2662 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
2664 Warning fixes from Maciej Stachowiak:
2665 * backtrace.h (scm_display_application, scm_backtrace): Add
2667 * debug.c (scm_m_start_stack): Make this function static.
2668 * fluids.h (scm_fluid_p): Add prototype.
2669 * procprop.c (scm_i_procedure_arity): Make this function static.
2670 * regex-posix.c (scm_regexp_error_msg): Make this function static.
2671 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
2672 * root.h (scm_dynamic_root): Add external prototype.
2673 * scmsigs.h (scm_usleep): Add external prototype.
2674 * script.h (scm_init_script): Use prototype, not K&R decl.
2675 * stacks.h (scm_stack_id): Add external prototype.
2676 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
2678 1998-09-30 Mark Galassi <rosalia@cygnus.com>
2680 * gh.h: took out the definitions of vset and vref, since they are
2681 replaced by the proper vector routines that correspond to the R4RS
2684 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
2686 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
2687 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
2688 third argument, a C expression that should result in a SCM value,
2689 which is used to initialize the variable. Reimplemented
2690 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
2693 * version.h (scm_libguile_config_stamp): Add prototype.
2694 (From Maciej Stachowiak.)
2696 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
2698 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
2699 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
2701 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
2703 * print.c (scm_iprin1): Rather than having one i, and using it in
2704 several places, declare a fresh i local to each block where it is
2705 used, and give it a signedness appropriate to its use in each case.
2706 (scm_iprlist): Same.
2708 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
2709 comparison warnings.
2711 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
2712 signed/unsigned clashes.
2714 * posix.h (scm_tmpnam): Added prototype.
2716 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
2717 scm_make_subclass_object): Add external prototypes.
2719 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
2720 comparison is okay here.
2722 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
2724 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
2725 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
2727 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
2730 * load.c (swap_port): Make this function static.
2732 * load.c (scm_search_path): Make max_path_len and max_ext_len
2733 unsigned, since they're compared against string sizes.
2735 * load.c (init_build_info): Make i unsigned.
2737 * ioext.h (scm_read_line): Add prototype.
2739 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
2740 scm_hash_fn_remove_x): Make hash bucket index local variable k
2741 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
2742 accurately as possible.
2744 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
2745 comparisons, and range checking to make sure those casts are
2748 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
2749 signed/unsigned comparisons.
2751 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
2752 avoid signed/unsigned comparisons.
2753 * smob.h (scm_numsmob): Change extern declaration to match.
2755 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
2756 avoid signed/unsigned comparisons.
2757 * ports.h (scm_numptob): Change extern declaration to match.
2758 (scm_current_load_port, scm_set_port_line_x,
2759 scm_set_port_column_x): New prototypes.
2761 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
2762 test code, and it causes warnings.
2764 * gh.h (gh_int2scmb, gh_uniform_vector_length,
2765 gh_uniform_vector_ref): Added prototypes.
2767 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
2768 debugging support unconditionally. That's backtrace.c, stack.c,
2769 debug.c, and srcprop.c.
2770 (EXTRA_libguile_la_SOURCES): Omit those from here.
2771 * Makefile.in: Regenerated.
2773 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2775 * options.c (scm_options): Bugfix: Allow empty list of options!
2777 * debug.c, debug.h (scm_single_step): Removed.
2778 (scm_with_traps): New procedure. This procedure could easily be
2779 written in Scheme but needs to be highly optimized.
2781 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
2783 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
2784 Check SCM_TRAPS_P before trapping.
2786 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
2788 Changes to avoid signed/unsigned comparison warnings.
2789 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
2790 (scm_gc_sweep): Make n and j local to the blocks they're used in,
2791 so they can have appropriate types for each application. Make i
2792 signed. Use initializers in some spots. I'll probably pay for
2794 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
2795 (scm_must_realloc): Make nm unsigned.
2796 (init_heap_seg): Make new_seg_index and n_new_objects signed.
2797 (scm_init_storage): Use prototype-style definition, and make the
2799 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
2800 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
2802 * filesys.c (scm_readlink): Make local vars rv and size ints, to
2803 avoid signed/unsigned comparison warnings, and because the return
2804 value of readlink may be -1. Don't bother casting the third
2805 argument to readlink.
2807 * filesys.c (scm_dirname, scm_basename): Move these to their own
2808 page, at the end of the file.
2809 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
2811 * eval.h (scm_eval_options_interface): Add external prototype for this.
2812 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
2814 * eval.c (scm_lookupcar1): Make this static.
2816 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
2817 Make these prototype declarations, not K&R-style.
2819 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
2820 unsigned comparison warning.
2822 * appinit.c: File removed. It had a single function in it, empty,
2823 whose reason for existence is explained in no documentation or
2824 comment. I think it's there as a default for some Tcl-style
2825 initialization, but Tcl abandoned that approach a while ago.
2826 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
2827 (BUILT_SOURCES): Remove appinit.x.
2828 * Makefile.in: Regenerated.
2830 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
2832 * Makefile.in: Regenerated using the last public version of
2833 automake, not the hacked Cygnus version.
2835 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
2837 Remove Totoro kludge.
2838 * Makefile.in, scmconfig.h.in: Regenerated.
2839 * init.c, readline.c: Don't check if TOTORO is #defined.
2841 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
2843 * Makefile.am: Adjust for new thread configuration system.
2844 (INCLUDES): Include the value of THREAD_CPPFLAGS.
2845 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
2847 (THREAD_LIBS): Definition deleted; automake will generate such
2848 things automatically.
2849 * Makefile.in: Regenerated.
2851 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
2853 Simplify smob and port marking; set the mark bit in the generic
2854 marking code, and make marker routines only responsible for
2855 turning up outgoing pointers.
2856 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
2857 before calling the marking function. Don't call the marking
2858 function if it's zero.
2859 * markers.c (scm_mark0): Just return #f. This function isn't
2860 necessary at all now, but it's harmless to call it. We'll leave
2861 it in so other folks' code doesn't croak at link time.
2862 (scm_markcdr): Don't call SCM_SETGC8MARK.
2863 * async.c (mark_async): Don't call SCM_SETGC8MARK.
2864 * dynl.c (mark_dynl_obj): Same.
2865 * root.c (mark_root): Same.
2866 * srcprop.c (marksrcprops): Same.
2867 * unif.c (markra): Same.
2868 * variable.c (scm_markvar): Same.
2869 * ports.c (scm_markstream): Same.
2870 (void_port_ptob): Specify zero for our marking function.
2871 * debug.c (debugobjsmob): Same.
2872 * dynwind.c (guardsmob): Same.
2873 * filesys.c (dir_smob): Same.
2874 * fluids.c (fluid_smob): Same.
2875 * fports.c (scm_fptob, scm_pipob): Same.
2876 * mallocs.c (mallocsmob): Same.
2877 * regex-posix.c (regex_t_smob): Same.
2878 * smob.c (freecell, flob, bigob): Same.
2879 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
2880 * throw.c (jbsmob, lazy_catch_funs): Same.
2882 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2884 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
2885 scm_copy_tree on code in order not to let memoized code to leak
2886 out. Thus, scm_copy_tree needs to copy vectors as well since
2887 quasiquote can introduce evaluated code also inside vector
2890 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2892 * eval.c (scm_copy_tree): Removed ability to copy vectors.
2894 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
2895 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
2898 * unif.c: Say that ivect and uvect are of type signed and unsigned
2899 long instead of int in commentary so that it correctly describes
2902 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2904 * stime.c: Removed declaration of strptime. (It should be
2905 declared by the system headers. If it turns out that some systems
2906 don't, we'll handle that then.) (Thanks to Greg Troxel.)
2908 * stime.h: Renamed TIMEH --> STIMEH
2910 * backtrace.c (scm_display_error, scm_display_backtrace): In order
2911 to increase portability, don't use structure assignment.
2912 (Thanks to Nicolas Neuss.)
2914 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
2916 (finalize_fd_sets): Added empty statement after last case label.
2917 (Thanks to Nicolas Neuss.)
2919 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
2922 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
2924 * init.c, readline.c: OK, I won't have these readline.x bug
2925 reports anymore. We've had them since April. The current reason
2926 is a completely unintelligible failure of totoro.red-bean.com to
2927 do the test for rl_getc_function in libreadline correctly. This
2928 kludge overrides the test if we're on totoro so that the snapshot
2929 generation process can work.
2931 * readline.c: Define a strdup replacement if not existent on system.
2933 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2935 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
2936 This change makes scm_make_vector R5RS compatible. We cannot keep
2937 the third argument since people want to be able to deduce the form
2938 of the C function call only by looking at R5RS. (At the same time
2939 we have removed some unnecessary complexity!)
2941 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
2942 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
2943 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
2944 argument in call to scm_make_vector.
2946 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2948 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
2949 This macro is useful in applications.
2951 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2953 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
2954 (scm_parse_path, scm_search_path): New Scheme level procedures.
2956 * load.h (scm_internal_parse_path, scm_parse_path,
2957 scm_search_path): Declared.
2959 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2961 * filesys.c (dirname, basename): New procedures.
2963 * init.c (scm_boot_guile_1): Removed condition around
2966 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
2967 new data type (guards) for representation of C level guards and
2968 data on the wind chain.
2969 (scm_internal_dynamic_wind): New function.
2971 * dynwind.h: Declare scm_internal_dynamic_wind.
2973 * root.h (scm_root_state): Added scm_cur_loadp.
2975 * root.c (mark_root): Added comment about cur_loadp.
2977 * load.c: #include "dynwind.h";
2978 (scm_primitive_load): Use scm_inner_dynamic_wind to update
2981 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
2983 * ports.c (current-load-port): New procedure.
2985 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2987 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
2988 not a tty, return #f.
2990 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
2991 to Julian Satchell and Roland Kaufmann.)
2993 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
2994 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
2996 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2998 * debug.h, debug.c (scm_start_stack): New function. Implements
2999 the guts of old scm_m_start_stack.
3001 * debug.c (scm_m_start_stack): Use scm_start_stack.
3003 * init.c (scm_start_stack, scm_restart_stack): Renamed to
3004 start_stack and restart_stack. (These have static scope.)
3006 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3008 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
3009 readline functions to come in release 2.3. (Thanks to Chet
3011 (handle_errors): Use the above functions.
3013 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3015 * readline.c: Improvements for readline support: Handle errors
3016 better; Implement before-read-hook.
3018 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3020 * init.c (scm_boot_guile_1), readline.c: Test for
3021 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
3022 assure that we have version >= 2.1.)
3024 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3026 * readline.c (scm_readline): Defer interrupts while we're calling
3029 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3030 away the string to add_history.
3031 (completion_function): Do completion for readline. (Thanks to
3033 (scm_filename_completion_function): New procedure: Filename
3035 (current_input_getc): New function. Use this one instead of
3036 standard getc from readline.
3038 * throw.c, throw.h (scm_handle_by_throw): New function: This
3039 handler throws errors to next handler on the dynwind chain.
3041 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3043 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3046 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3048 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3050 (scm_procedure_properties): Modified to return arity together with
3052 (scm_procedure_property): Added the read-only property `arity'.
3053 (scm_set_procedure_property_x): It is an error to set the `arity'
3056 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3057 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3059 * procprop.h (scm_sym_arity): New symbol.
3061 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3062 to set the dispatch procedure of an operator or entity object.
3064 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3065 Made procedure slots read-only.
3067 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3068 scm_tcs_cons_gloc case in zero args switch; Fixed args
3069 construction for operators in scm_tcs_cons_gloc case in two args
3072 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3074 * fluids.c: Removed use of assert.h (in order to avoid
3077 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3079 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3081 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3082 change makes the evaluator safer at the cost of evaluation speed.
3083 It handles the case when the user has added a non-immediate
3084 improper end of the application form, e.g., `(+ 0 . x)'.
3085 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3086 minimize the extra cost as much as possible. The new code is
3087 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3088 problem with structs planted directly in the code (e.g. by a
3089 macro). This no longer causes segmentation fault. (Thanks to
3092 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3093 arg `proc' in order to be able to throw errors; New argument
3096 * Removed extra #include "debug.h"
3098 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3100 * scmsigs.c: Declare usleep as returning void on some systems.
3101 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3104 * coop.c (usleep): Return void on some systems.
3106 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3108 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3110 * coop.c: Changed return type of usleep to int.
3112 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3113 isn't found in the OS.
3115 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3116 isn't enabled. (Thought that I had made this change ages ago...)
3118 * iselect.c: Declare bzero if not defined by OS.
3120 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3122 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3123 condition. (Thanks to John Tobey.)
3125 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3126 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3129 * __scm.h: Start the long-term project of moving to POSIX threads.
3130 Phase 1: Classification of all critical sections.
3131 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3132 for A sections. (See comments in __scm.h for details.)
3134 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3135 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3137 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3139 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3140 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3141 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3142 dependencies on $(srcdir)/Makefile.in
3143 $(top_builddir)/config.status in order to avoid circularity.
3145 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3146 from argc if argc was 0 initially.
3148 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3149 in generation of libpath.h.
3151 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3153 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3154 libguile from 2 to 3.
3156 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3158 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3160 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3162 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3163 scm_set_port_column_x, scm_port_filename,
3164 scm_set_port_filename_x): Removed optional arguments. Added
3165 proper argument checking.
3167 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3168 stack size in machine words.
3170 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3171 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3172 to Ole Myren Röhne.)
3174 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3176 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3177 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3179 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3182 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3183 procedure apply: Copy argument lists before pushing them unto the
3184 environment so that the environment won't get mutated due to
3185 manipulation of procedure arguments. This should perhaps be
3186 regarded as a temporary solution until someone finds a more
3187 efficient one. (Thanks to Maciej Stachowiak.)
3189 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3191 * script.c (scm_compile_shell_switches): Use "guile" as default
3192 zero arg if argc is NULL.
3194 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3196 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3197 is zero. (Thanks to Dirk Herrmann.)
3199 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3201 * ports.c (scm_add_to_port_table): First line is now line 0
3202 (was 1). (Interface changed according to suggestion by Per
3205 * backtrace.c (display_header): Add 1 to line and column numbers
3206 when presenting them to the user.
3208 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3209 from debug.c --> eval.c
3211 * eval.h, eval.c (scm_eval_options_interface): New options
3213 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3214 i.e. stacks for new threads.
3216 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3218 * eval.c (unsafe_setjmp): Removed with #if 0.
3220 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3223 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3224 to avoid compiler warnings.
3226 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3228 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3230 * throw.c (handler_message): Print message on current error port
3231 instead of default error port. (Thanks to Maciej Stachowiak.)
3233 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3235 * ports.c (scm_add_to_port_table): allocate in units of
3236 struct scm_port_table *, not struct scm_port_table.
3237 * posix.c (scm_close_pipe): remove the port from the port table
3239 Thanks to Rob Engle for both fixes.
3241 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3243 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3244 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3246 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3248 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3250 * backtrace.c (display_error_body, display_backtrace_body),
3251 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3252 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3253 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3254 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3257 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3258 don't receive the jmpbuf arg anylonger.
3259 (scm_catch): Don't accept a #f tag.
3260 (scm_throw): Check that key is a symbol.
3261 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3263 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3265 * async.c (async_pending): Removed declaration.
3267 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3269 * dynwind.c (scm_wind_chain): New debug function.
3271 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3272 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3273 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3274 extra layer of functions around the body and handler of a thread.
3275 This extra layer makes sure that the handler is called in the
3276 dynamic context of the surround (= empty dynwind list), but under
3277 the *dynamic root* of the body. We can not use the dynamic root
3278 of the surround since that root belongs to another thread => stack
3279 is not handled correctly. It may seem ugly to use this extra
3280 layer, but the extra cost in terms of execution time is really
3281 negligible compared to the total amount of time required to create
3282 a thread, and it would reduce maintainability to duplicate the
3283 crucial and complicated steps performed by cwdr.
3285 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3286 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3287 get re-enabled. The important effect of this is that interrupts
3288 are blocked during thread switching so that thread data structures
3289 don't risk getting messed up by an unfortunate signal.
3290 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3291 seems to do more aggressive optimization which actually move
3292 instructions around in these macros in a fatal way. Therefore:
3293 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3294 just superstitious...)
3295 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3296 This macro should be used instead of SCM_ASYNC_TICK since the
3297 latter doesn't do context switches any more.
3299 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3300 instead of SCM_ASYNC_TICK.
3302 * coop.c, iselect.c: Since thread switches are now performed with
3303 interrupts masked, we can't use the old mechanism of delivering
3304 signals immediately when they arrive. Signals must instead be
3305 delivered when the asyncs run *after* the end of the critical
3306 section in scm_internal_select. But this also means after context
3307 switch so that the signal will be delivered to a different thread.
3308 To avoid this, I have changed the protocol of
3309 coop_wait_for_runnable_thread and friends so that they are allowed
3310 to return the original thread. So, if a signal arrives during
3311 scm_internal_select, we won't any longer be forced do a context
3312 switch, but can remain in the same thread and deliver the signal
3315 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3316 scm_asyncs_pending and made it global.
3318 * iselect.c: Small fixes.
3320 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3321 coop_condition_variable_init, coop_condition_variable_wait,
3322 coop_condition_variable_signal): Changed return type from `void'
3323 to `int'. This is to adhere closer to the pthreads interface.
3324 This, in turn, is part of an attempt to provide C versions of the
3325 mutex and condition variable primitives which can be part of a
3326 frontend to COOP or pthreads.
3328 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3329 coop_condition_variable_destroy): New functions.
3331 * coop-threads.c (scm_wait_condition_variable): Use
3332 coop_condition_variable_wait_mutex.
3334 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3335 Definitions moved to coop-defs.h.
3337 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3338 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3339 scm_cond_destroy): New C interface to mutecis and cond vars.
3341 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3343 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3345 * iselect.c: Now several threads can wait on the same file
3346 descriptor. The behaviour is compatible with OS select: All
3347 threads waiting for the fd return with the same status.
3349 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3351 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3352 Can spawn a thread from application C code.
3354 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3356 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3357 gh_doubles2scm): New functions.
3359 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3361 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3362 commented-out version of gh_eval_str()
3364 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3366 * socket.c (scm_bind): free soka after use.
3368 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3370 * stime.c (tzvar): new variable.
3371 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3372 avoid memory leaks when allocating.
3374 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3376 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3379 * gc.c, tags.h: Doc fixes.
3381 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3383 * eval.c (macro-eval!): Removed. This function was a design bug.
3384 It allowed memoized code to leak out to the scheme level. Most
3385 things that you could do with `macro-eval!' can be done with
3388 1997-12-20 Tim Pierce <twp@skepsis.com>
3390 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3391 scm_fgets now depends on ftell(3) to know how many bytes were
3394 1997-12-15 Tim Pierce <twp@skepsis.com>
3396 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3397 dealing with strings.
3399 1997-12-13 Tim Pierce <twp@skepsis.com>
3401 Make %read-line more suitable for implementing read-line efficiently.
3402 * ioext.c (scm_read_line): Strip the terminating newline from a
3403 string, and return a cons of the string and its terminator.
3405 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3406 of the string that is read is stored in this memory location.
3407 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3408 * genio.c, genio.h (scm_do_read_line): Update caller.
3409 * ports.h (scm_ptobfuns): Update typedef.
3410 * fports.c (scm_fptob, scm_pipob): Update struct.
3412 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3414 * filesys.c (set_element): Return file descriptor.
3415 (fill_select_type): Return the highest file descriptor.
3416 (scm_select): Tell select about the highest file descriptor. On
3417 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3418 Therefore the extra overhead for calculating the maximum fd seems
3419 to be more than compensated. Is this correct? In any case,
3420 scm_internal_select will be much faster with this info.
3421 (scm_select, fill_select_type, set_element): Don't accept any kind
3422 of object in the file descriptor list or vector.
3424 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3426 * iselect.c (finalize_fd_sets): Bugfix.
3428 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3430 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3431 when using scm_internal_select (since we might switch to another
3434 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3436 * simpos.c (scm_system): always define: use sysmissing if not
3437 available. Check for HAVE_SYSTEM instead of _Windows (does
3438 Windows lack system or does it have an unusable one?).
3439 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3440 Let the argument be optional: if not supplied, call system(NULL).
3442 * ports.c (scm_close_port): relax the type check from OPPORTP to
3443 PORTP; closing a closed port is allowed.
3445 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3447 * fports.c (scm_fgets): Return if the last char in a chunk is
3448 newline. When fgets returns a string whose length is `size-1', it
3449 is ambiguous whether a whole line was retrieved, so we must check
3450 explicitly whether a line terminator is present.
3452 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3454 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3455 before taking the CDR. (Thanks to Harald Meland.)
3457 * filesys.c (scm_stat): Slightly optimized.
3459 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3461 * ports.c (scm_close_port): Make sure the port is open before
3464 * guile-snarf.in: Pass args through to gcc in a way that preserves
3465 whitespace boundaries. (Thanks to Greg Badros.)
3467 1997-12-02 Tim Pierce <twp@skepsis.com>
3469 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3470 statement. (Thanks to Doug Evans for pointing this out.)
3472 1997-12-01 Tim Pierce <twp@skepsis.com>
3474 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3476 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3478 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3479 errno macro expansion of this field name. (errno is a C
3480 preprocessor macro on some systems.)
3482 1997-11-29 Tim Pierce <twp@skepsis.com>
3484 * iselect.c: Doc fix.
3486 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3488 * init.c (scm_start_stack): Removed initialization of
3489 scm_the_last_stack_var.
3491 * backtrace.h: Declare scm_the_last_stack_var.
3493 * backtrace.c: Define scm_the_last_stack_var.
3495 * root.c (mark_root): Don't mark the_last_stack_var.
3497 * root.h (scm_root_state): Removed the_last_stack_var.
3499 * throw.c: Added #include "fluids.h"
3500 (ss_handler): `the-last-stack' is now a fluid.
3502 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3503 --> the_last_stack_fluid.
3505 * backtrace.c: Added #include "fluids.h"
3506 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3507 (scm_backtrace): `the-last-stack' is now a fluid.
3509 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3510 after scm_init_fluids.
3512 1997-11-28 Tim Pierce <twp@skepsis.com>
3514 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3516 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3517 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3519 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3521 * iselect.c (coop_next_runnable_thread,
3522 coop_wait_for_runnable_thread): Disable interrupts so that no
3523 async is executed before a potential error_revive.
3524 (scm_internal_select): Disable interrupts during the parts of the
3525 code which manipulate the sleep queue and the file descriptors.
3527 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3529 * Makefile.am: Added iselect.c and iselect.h.
3531 * coop.c (coop_qinit): Initialize fields used by
3532 scm_internal_select.
3533 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3534 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3535 replacement in iselect.c.
3536 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3537 coop_join): If GUILE_ISELECT enabled, use
3538 coop_wait_for_runnable_thread instead of
3539 coop_next_runnable_thread.
3540 (usleep, sleep): New replacements for system functions if
3541 GUILE_ISELECT is enabled.
3543 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3545 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3547 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3548 iselect.h. Implement Scheme level `select' using
3549 scm_internal_select. (See NEWS.)
3551 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3553 * init.c: Call scm_init_iselect.
3555 * iselect.h, iselect.c: New files. Implements
3556 scm_internal_select. (See NEWS.)
3558 1997-11-27 Tim Pierce <twp@skepsis.com>
3560 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3561 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3562 and scm_must_free, since ultimately the string returned will be copied
3563 by scm_makfrom0str anyway. Also, read any characters that may have
3564 been pushed onto the port with scm_ungetc.
3565 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3566 * ioext.c (scm_read_line): Free string after Guilifying it.
3567 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.

3577 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3578 gh_repl (argc, argv).
3580 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3582 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3583 and to invoke scm_shell().
3584 (gh_launch_pad): took out the loading of boot-9.scm from here,
3585 since it is probably best to let the user control that. In fact,
3586 gh_repl() now invokes scm_shell() which does that.
3588 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3590 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3593 1997-11-22 Tim Pierce <twp@twp.tezcat.com>

3607 (gh_uniform_vector_ref): started implementing the uniform types in
3610 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
3612 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3613 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3615 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3617 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
3618 configure.in was changed).
3620 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
3622 * Makefile.am (modinclude_HEADERS): Include readline.h here.
3623 * Makefile.in: Regenerated.
3625 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
3627 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
3628 OPORT is an `open' port, not an output port.
3630 * filesys.c (scm_close, set_element, get_element, scm_chown,
3631 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use

3636 scm_set_port_filename_x, scm_port_mode,
3637 scm_close_all_ports_except, scm_set_current_output_port,
3638 scm_set_current_error_port): Likewise
3639 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
3640 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
3642 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
3643 * backtrace.c (display_backtrace_body): Likewise
3644 * fports (scm_setvbuf): Likewise
3645 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

3652 Minor problems with substring-related tag changes.
3653 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
3654 exactly what we want to leave in to detect substrings.
3655 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
3656 * tags.h: Fix diagrams and comments describing the S tag bit;
3657 remove vestigial remarks about the D tag bit.
3658 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
3659 * strings.c: Formatting tweaks.
3661 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
3662 variable first; then SCHEME_LOAD_PATH, with a warning message.
3663 (scm_parse_path): New function.
3664 * script.c: Doc fixes.
3666 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
3668 Readline support, from Daniel Risacher.
3669 * readline.c, readline.h: New files.
3670 * init.c: #include "readline.h".
3671 (scm_boot_guile_1): Call scm_init_readline, if we have it.
3672 * Makefile.am (libguile_la_SOURCES): Include readline.c.
3673 * Makefile.in: Regenerated.
3674 * scmconfig.h.in: Regenerated, after change to ../configure.
3676 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3678 * gh.h: gh_vector_set -> gh_vector_set_x
3680 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3682 * gh_data.c (gh_vector_set_x): changed name to make it consistent
3683 with the ! -> _x mapping when going from Scheme to C.
3685 1997-10-19 Mark Galassi <rosalia@cygnus.com>
3687 * gh.h (gh_reverse):
3695 (gh_assoc): added these gh_ functions implemented as macros.
3697 * gh_predicates.c (gh_null_p):
3698 (gh_string_equal_p): added these two missing predicates.
3700 * gh_list.c (gh_append):
3705 (gh_set_cdr_x): added these routines as I go through and try to
3706 complete the picture R4RS functions that should be mirrored in the
3709 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3711 * tags.h (scm_tc7_substring): Changed the comment and code to
3712 conform with the changes below. Folks! We have suddenly two new
3713 free tc7 codes!!! Jummy, jummy!
3715 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
3717 * Makefile.in: Rebuilt.

3738 (scm_tc7_mb_string): Removed.
3739 (scm_tc7_mb_substring): Removed.

3742 Don't include "mbstrings.h".
3743 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
3744 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
3746 Don't include "mbstrings.h".
3747 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
3748 (SCM_SYMBOL_SLOTS): Define as 4.

3750 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
3751 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
3752 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
3753 struct.c, threads.c, throw.c, unif.c, variable.c: Use new

3773 1997-10-12 Mark Galassi <rosalia@cygnus.com>
3775 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
3777 * gh_test_c.c (c_vector_test): some improvements on the vector
3780 * gh.h (gh_vector): this used to exist but do the wrong thing.
3781 Now it (almost) does the right thing, though it takes a list
3782 instead of the individual arguments. I need to see how it could
3784 (gh_list_to_vector): added this function as a macro. Corresponds
3785 to Scheme's (list->vector ...).
3786 (gh_vector_to_list): added this function as a macro. Corresponds
3787 to Scheme's (vector->list ...).
3789 * gh_data.c (gh_vector_ref): renamed from gh_vref to
3790 gh_vector_ref, so that it resembles the Scheme routines more.
3791 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
3792 resembles the Scheme routines more.
3793 (gh_make_vector): this used to be (stupidly) called gh_vector().
3794 This is the right name, since it does the same thing as the Scheme
3795 (make-vector ...) procedure.
3797 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
3799 * ports.h: #include "libguile/print.h"
3801 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
3802 Some indentation fixes.
3804 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
3805 longer a user field; New field: class_flags.
3807 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
3809 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
3811 * gh_data.c (gh_bool2scm): new function which replaces
3812 gh_int2scmb(), which is now tagged as obsolete.
3814 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
3816 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
3817 macros should by convention not test for NIMPness.)
3818 (SCM_COERCE_OPORT): Adjust indentation.
3820 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
3821 SCM_NIMP test before SCM_PRINT_STATE_P.
3823 * struct.c, struct.h, gc.c: Renamed:
3824 scm_struct_i_layout --> scm_vtable_index_layout
3825 scm_struct_i_vcell --> scm_vtable_index_vcell
3826 scm_struct_i_vtable --> scm_vtable_index_vtable
3827 scm_struct_i_printer --> scm_vtable_index_printer
3828 scm_struct_i_vtable_offset --> scm_vtable_offset_user
3830 * struct.c (scm_print_struct): Use new printer slot; Default
3831 printing: Also output hex code of vtable so that type identity
3832 will be indicated as well.
3833 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
3834 Removed struct_printer_var; Removed struct-vtable-offset;
3835 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
3836 vtable-offset-user): New constants.
3838 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
3839 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
3840 If this slot contains a procedure, use that to print structures of
3841 the type represented by this vtable.
3843 * print.c (scm_iprin1): Don't print arguments of macro
3844 transformers. (They are always: exp env.); Bugfix: Unmemoize
3845 transformer source with correct environment.
3847 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
3849 Streamlining of call-with-dynamic-root:
3851 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
3852 there is now only one catch.
3853 (cwdr_outer_body): Removed.
3854 (cwdr_handler): New function.
3855 (scm_internal_cwdr): New function to perform the function of cwdr
3856 but take args that are more useful to C code. Also, the handler
3857 is now invoked *outside* of the new dynamic root, like the docs
3858 say. We no longer have to catch absolutely all errors, the caller
3859 is responsible for using a handler that does not throw, if he
3861 (cwdr): Reimplemented in terms of scm_internal_cwdr.
3862 * root.h (scm_internal_cwdr): New prototype.
3864 Even more but risky streamlining:
3866 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
3867 allocation of the jumpbuf of a root continuation. The changes
3868 below are controlled by it. They are now deactivated.
3869 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
3870 the JMPBUF of the scm_rootcont to NULL before returning.
3872 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
3873 when they are non-NULL.
3874 (scm_gc_mark): Likewise, mark only when non-NULL.
3876 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
3877 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
3879 * gc.c (scm_done_malloc): New function.
3880 gc.h (scm_done_malloc): New prototype.
3882 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.

3889 a certain value is acceptable as a port argument.
3890 (scm_print_state_vtable): New variable.
3891 (scm_free_print_state): Set `revealed' field to false.
3892 (scm_iprin1): Call user supplied closure printer with
3893 scm_printer_apply. Print in the traditional way when there isn't
3894 one or when it returns #f.
3895 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
3896 Accept a port/print-state pair in addition to just a port.
3897 (scm_prin1): Don't return the print_state to the pool when it has
3899 (scm_printer_apply): Set `revealed' field of print_state to true.
3900 (scm_init_print): Set scm_print_state_vtable.
3901 (print_state_fluid, print_state_fluid_num): Removed.
3903 * throw.h (scm_handle_by_proc_catching_all): New prototype
3904 throw.c (scm_handle_by_proc_catching_all): New function
3906 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
3908 * Makefile.in: Regenerated with automake 1.2c.
3910 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
3912 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
3913 was looping endlessly.
3915 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
3917 * strports.c (scm_eval_string): Don't close the port.
3919 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
3920 former returns a nice normal integer. (Thanks to Daniel
3923 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
3925 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
3926 makefile variable as a build parameter called LIBS. The
3927 build-guile program will use this, for the time being.
3928 * Makefile.in: Regenerated.
3930 Thanks to Shiro Kawai:
3931 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
3932 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
3935 * Makefile.in: Regenerated with automake 1.2a.
3937 * script.c (scm_compile_shell_switches): If we hit the -c or --
3938 arguments, don't set the car of (command-line) to scm_usage_name,
3939 the prettified name of the guile executable; give it the full
3940 path, the way shells usually handle $0.
3942 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3944 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
3945 Scheme-level name `array-map' and renamed `serial-array-map' to
3946 `serial-array-map!'.
3948 * backtrace.c: Introduced exception handlers which now enclose
3949 `display-error' and `display-backtrace' so that error reporting
3950 won't get into infinite loops if an error occurs during displaying
3951 of the error. This can very easily happen with user supplied
3952 print call-back routines.
3954 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3956 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
3957 the names `serial-array-map' and `array-map' should be removed.)
3959 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
3961 * init.c (scm_boot_guile_1): Added scm_init_objects ().
3962 Added #include "objects.h"
3964 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
3965 Add #include "feature.h".
3967 * Makefile.am (libguile_la_SOURCES): Added objects.c.
3968 (modinclude_HEADERS): Added objects.h.
3970 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
3971 This test is needed at many places in the code and should be
3972 abstracted. (Motivated by the need of this test in libguiletk.)
3974 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
3975 (scm_eval_string), load.c (scm_primitive_load,
3976 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
3977 Use SCM_EOF_OBJECT_P.
3979 * eval.c (scm_init_eval): Add feature `delay'.
3981 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3983 * scmhob.h: Removed.
3985 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3987 * list.h (SCM_LISTn): New macros. Make list creation in C code
3988 prettier. The idea comes from STk.
3990 * sequences.h, sequences.c, append.h, append.c: Removed. These
3991 files implemented non-R4RS operations which would encourage
3992 non-portable programming style and less easy-to-read code.
3994 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
3997 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
3998 sequences.h, #include append.h.
4000 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
4003 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
4005 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
4007 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
4009 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>

4013 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
4016 * smob.c (scm_smob_prehistory): Create two objectsmobs with
4017 adjacent smob numbers.
4019 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4021 * procprop.h: Added declaration of scm_i_inner_name.
4023 * gsubr.c: New global symbol scm_i_inner_name.
4025 * debug.c (scm_procedure_name): Try procedure property
4026 `inner-name' if `name' fails.
4028 * print.c (scm_iprin1): Use scm_macro_name.
4030 * eval.c (scm_m_define): Give names to macros as well; Only the
4031 first top-level definition gives a procedure/macro a name.
4032 Otherwise confusing names can turn up in backtraces.
4033 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4034 `name'; Give names to macros as well.
4036 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4037 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4040 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4042 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4044 (prinmacro): Removed. The code has been moved/merged into print.c
4045 in order to decrease code redundancy. We want macros to print in
4046 a way equivalent to procedures, and it would be silly to duplicate
4047 the required code. (We don't want to maintain two places.)
4048 (macrosmob): Print field is now a NULL pointer.
4050 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4051 scm_macro_transformer): New prototypes.
4052 (scm_tc16_macro): Declared.
4054 * print.c (scm_iprin1): Added code for printing of macros. Macros
4055 are now printed in a way equivalent to procedures.
4057 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4059 * procs.h (scm_closure_p): Added declaration.
4061 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4063 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4064 Shouldn't pass "heap" as the subr name.
4066 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4068 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4069 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4070 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4071 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4072 SCM_BOOL_T. Any non-false value is true.
4074 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4076 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4077 scm_gensym): Added prototypes.
4079 * symbols.c (scm_gensym): New function. This will speed up
4080 certain types of applications (such as macro systems) which
4081 generate lots of symbols.
4083 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4085 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4087 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4089 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4090 specifier, since (2) or (2 . 3) would cause SEGV.
4091 (scm_transpose_array): more argument checking fixes.
4093 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4095 * Makefile.in: Regenerated.
4097 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4099 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4101 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4103 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4105 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4107 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4108 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4111 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4112 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4113 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
4114 scm_array_p, scm_array_rank, scm_array_dimensions,
4115 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
4116 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
4117 scm_array_prototype): Added case scm_tc7_wvect.
4119 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
4121 * errno.h: prototype for scm_strerror.
4122 * error.c (scm_strerror): new procedure.
4124 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4126 * list.c (scm_list_append_x): Allow non-pair as last argument.
4127 This is consistent with the R4RS append and is probably the
4128 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4130 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4132 * stime.h: prototype for scm_times.
4133 * stime.c (scm_times): new procedure.
4134 * ioext.c (scm_fseek): if the first argument is a file descriptor
4136 (scm_ftell): if the first argument is a file descriptor call lseek
4138 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
4139 * filesys.c (scm_chmod): if the first argument is a file descriptor,
4141 (scm_chown): if the first argument is a port or file descriptor,
4143 (scm_truncate_file): new procedure.
4144 Add DEFER/ALLOW INTS to a few other procedures.
4145 (scm_fsync): new procedure.
4146 (scm_open_fdes): new procedure.
4147 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
4149 (scm_fcntl): the first argument can now be a file descriptor. The
4150 third argument is now optional.
4152 * posix.c (scm_execl, scm_execlp): make the filename argument
4153 compulsory, since omitting it causes SEGV.
4154 (scm_sync): return unspecified instead of #f.
4155 (scm_execle): new procedure.
4156 (environ_list_to_c): new procedure.
4157 (scm_environ): use environ_list_to_c. disable interrupts.
4158 (scm_convert_exec_args): take pos and subr arguments and
4159 improve error checking.
4161 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4163 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4164 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4165 argument to SCM_ASSERT. Furthermore, the name of the function
4166 should be passed as first argument when signalling
4167 SCM_WNA. (Thanks to Thomas Morgan)
4169 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4170 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4171 dispatches on the number of actual args has a default case
4172 reporting an internal error. This is a vestige from a version
4173 that mallocated a SCM vector to hold the arguments. In the
4174 current version this check is too late: if it ever happens we will
4175 have already overstepped the bounds of the array.
4177 Also, the patch [...] adds a check for too many actual arguments."
4179 mdj: Removed check for "internal programming error".
4181 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4183 * gh_io.c (gh_write): New function.
4185 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
4186 throw.c (scm_internal_stack_catch): New sibling to the other catch
4187 functions. Code moved from gh_eval.c.
4188 throw.h: Added header.
4189 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
4190 scm_internal_stack_catch.
4192 Tue Jul 29 01:03:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4194 * ioext.h: fix up prototypes.
4195 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
4196 Scheme name is now dup->fdes.
4197 (scm_dup_to_fdes): make the second argument optional and
4198 fold in the functionality of scm_primitive_dup.
4199 (scm_primitive_dup): deleted.
4201 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
4203 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
4204 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
4205 ultrix are defined. Use setvbuf instead of setbuf.
4206 (scm_setvbuf): new procedure.
4207 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
4208 (scm_setfileno): moved from ioext.c.
4209 (scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
4210 (top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.

4214 * fluids.c (scm_fluid_p): New function.
4215 * fluids.h (scm_fluid_p): New prototype.

4220 state as nested data while they are printed.
4221 (print_state_fluid, print_state_fluid_num): New variables.
4222 (scm_init_print): Initialize them.
4223 (scm_iprin): If print_state_fluid carries a print_state, use that
4224 instead of creating a new one.
4225 (scm_printer_apply, apply_stub, struct apply_data): New
4226 definitions to help with calling printer functions written in
4228 * print.h (scm_printer_apply): New prototype.
4230 * struct.c (scm_print_struct): Use scm_printer_apply to call the
4231 user defined struct printer.

4241 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
4242 SCM_ASSERT: arg comes before pos.
4244 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4246 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
4247 to a list of length zero correctly.
4249 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

4265 * ioext.h: removed scm_duplicate_port prototype.
4267 * ioext.c (scm_primitive_dup2): return the new file descriptor
4268 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
4270 (scm_fdopen): bug fix: don't try to make port unbuffered until its
4271 stream has been set.
4272 (scm_duplicate_port): deleted, there's now an implementation in
4274 (scm_primitive_dup2): do nothing if newfd == oldfd.
4276 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
4278 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

4284 * fluids.c (next_fluid_num): don't do
4285 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
4287 * ports.h: prototypes too.
4288 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
4290 * fports.h: prototype too.
4291 * fports.c (scm_evict_ports): moved from ioext.c.
4293 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
4295 * ports.c (scm_close_port): return a boolean instead of unspecified.
4296 throw an error if an error other than EBADF occurs.
4298 * filesys.h: scm_close prototype.
4299 * filesys.c (scm_close): new procedure, can close file descriptors
4300 and ports (scsh compatible).
4302 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
4305 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
4307 * fluids.c, fluid.h: New files.
4308 * Makefile.am (libguile_la_SOURCES): Added "fluids.c".
4309 (modinclude_HEADERS): Added "fluids.h"

4318 (scm_make_root): Call scm_copy_fluids to make fluid bindings
4319 unique for the new root when it has a parent.
4321 * smob.h: Include "libguile/print.h" to make scm_print_state
4324 * dynl.c (free_dynl_obj): New function to free the dynamic object
4325 data. (dynl_smob): Use it.
4326 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4327 the dynamic object data below the linking of the object to avoid
4328 memory leak when the linking code throws an error. Now the code
4329 leaks a whole dynamically linked library when must_malloc throws,
4330 but that should be much less likely.
4332 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4334 Changes to compile under gnu-win32, from Marcus Daniels:
4335 * stime.c (tzset): If tzset isn't provided, make it a NOP.
4336 (scm_localtime): Change SCM_EOF to SCM_EOL.
4337 (scm_mktime): Likewise.
4338 * socket.c: Don't include sys/un.h unless autoconf tells
4339 us Unix domain sockets are available.

4341 (scm_addr_vector): Likewise.
4342 (scm_init_addr_buffer): Likewise.

4350 (scm_setpwent): For setpwent.
4351 (scm_setegid): For setegid.
4352 * net_db.c (scm_inet_netof): Don't include unless support

4368 scm_misc_error, not SCM_EOF.
4370 * error.c (scm_wta): Pass SCM_EOL to scm_misc_error as the list of
4371 arguments for formatting the error message, not SCM_BOOL_F. I
4372 think this is left over from the (eq? '() #f) days.
4374 * read.c (recsexpr): Give this a dummy definition if
4375 DEBUG_EXTENSIONS isn't #defined.
4377 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
4379 * coop-threads.c (scm_wait_condition_variable): Lock mutex again
4382 Thu Jul 3 16:31:24 1997 Marius Vollmer <mvo@zagadka.ping.de>

4389 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
4390 alloca.lo will be included in @LIBLOBJS@. Something better than
4391 this should be possible.
4392 * Makefile.in: Regenerated.
4394 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4396 * simpos.h: prototype for scm_primitive_exit.
4397 * simpos.c (scm_primitive_exit): new procedure, terminates the
4398 process without unwinding the stack.
4400 Sat Jun 28 03:45:25 1997 Tim Pierce <twp@twp.tezcat.com>
4402 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
4403 argument and logior its components together, so the user doesn't
4404 have to do this explicitly. Also, if regexp/basic is supplied, then
4405 turn off REG_EXTENDED.
4406 (scm_init_regex_posix): New regexp/basic symbol.
4407 (REG_BASIC): #define this if it is not already present.
4409 Fri Jun 27 20:36:35 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4411 * Makefile.am (libguile_la_LIBADD): Include @ALLOCA@.

4420 years in usage message.
4422 * Makefile.am (libguile_la_LDFLAGS): Bump library version.
4423 * Makefile.in: Regenerated.
4425 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
4426 flag; I don't think we support it.
4427 (scm_make_regexp): Make sure the user doesn't pass the
4430 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
4432 (scm_init_regex_posix): Define constants for the REG_mumble flags;
4433 name them according to the SCSH convention: regexp/mumble.
4435 * regex-posix.h (scm_make_regexp, scm_regexp_exec): Update prototypes.
4437 Mon Jun 23 18:44:49 1997 Jim Blandy <jimb@floss.red-bean.com>

4440 Makefile directory variables. Print a message, but don't print
4442 (versiondat.h): Print a message, but don't print all the commands.
4443 * load.c: #include "alist.h".
4444 (init_build_info): New function.
4445 (scm_init_load): Call it.
4446 * Makefile.in: Regenerated.
4448 Sun Jun 22 19:12:58 1997 Jim Blandy <jimb@floss.red-bean.com>
4450 * root.c: Establish a reliable catch-all handler for the new root.
4451 After all the Scheme handler function might signal an error too,
4452 and we don't want to lose that.
4453 (cwdr_inner_body): Renamed from cwdr_body.
4454 (cwdr_outer_body): New function, to establish the user's handler,
4455 and pass control to cwdr_inner_body.
4456 (cwdr): Establish the reliable catch-all handler here, and pass
4457 control to cwdr_outer_body.
4458 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
4459 the user's handler through to cwdr_outer_body.
4460 * throw.c (scm_handle_by_message): Move guts into....
4461 (handler_message): New static function.

4463 * throw.h (scm_handle_by_message_noexit): New prototype.
4465 * __scm.h: (SCM_FENCE): New macro: optimizer will not move code
4466 across this. Only works on GCC. Otherwise, we hope for the best.
4467 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4468 the feeling that real thread systems will not need this...
4470 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4472 Try to detect when people are using one version of libguile and a
4473 different version of ice-9. People have been skewing things and
4474 sending in bug reports.
4475 * Makefile.am (versiondat.h): New file to generate.
4476 * version.c: #include "versiondat.h", to get version info.
4477 (scm_libguile_config_stamp): New function.
4478 * script.c: #include "version.h".
4479 (scm_compile_switches): Call scm_version to get version number.
4480 * scmconfig.h.in, Makefile.in: Regenerated.
4481 * Makefile.in: Regenerated.
4483 * Makefile.am (ETAGS_ARGS): Catch SCM_PROC, etc. so we can find
4484 primitive definitions under their Scheme names.
4486 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4487 1:2. Helps avoid confusion between installed and uninstalled libs.
4489 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
4492 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
4493 backslash from definition; this should be used like: GDB_INTERFACE;
4495 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4497 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
4498 new port unbuffered until its stream has been set.
4500 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
4502 * ports.h: new prototype.
4503 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
4505 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
4507 Make things compile neatly under Sun's C compiler.
4508 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
4509 * extchrs.c (xmbtowc): Make the second arg a normal char, not
4510 unsigned, because that's what the ANSI function takes.
4511 * extchrs.h (xmbtowc): Corresponding change to prototype.
4512 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4514 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
4515 argument plain char *.
4516 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
4518 * tag.c (scm_tag): Remove unreachable statement.
4519 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4520 top of the word, it should be unsigned.
4522 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4523 is defined, to avoid warnings; it's only used in the
4524 conflict-checking code. Which might go away anyway.
4525 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4526 conditionals; put the label definition in an #if too, to stifle
4529 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4530 ChangeLog-threads in the distribution.
4531 * Makefile.in: Regenerated.
4533 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4535 * guile-snarf.in: Changed regexp to support CPPs that insert
4536 whitespace between lexical tokens (which munges the `%%%' snarf
4539 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4541 * load.c (scm_init_load_path): Append $(datadir)/guile to
4542 %load-path, so modules do not have to be installed in Guile's
4543 current version directory.
4545 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
4547 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
4548 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
4549 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
4550 call the sysdep functions with deferred ints.
4551 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
4552 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
4553 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
4556 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
4559 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
4561 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
4563 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
4565 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
4568 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
4570 * eval.c (scm_lookupcar1): New procedure to cope with a race
4571 condition during lookup (when using threads).
4572 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4573 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4576 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4578 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4579 supplied. (Change from Tim Pierce.)
4581 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4583 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4584 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4585 default and not `()'. `#f' is the canonical non-value in Scheme,
4588 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4590 * struct.c (struct_printer): New variable that holds a handle on
4591 the Scheme variable *struct-printer*. This variable can be set by
4592 Scheme code to override the printing of structures.
4593 (scm_print_struct): If struct_printer is set, call it. If it is
4594 not set, or returns #f, print the structure in the old fashion.
4595 Include "eval.h" for scm_apply.
4597 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4599 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4600 scm_struct_i_n_words to get the number of fields, not
4601 -scm_struct_n_extra_words.
4603 On the route to fancier struct printing:
4604 * struct.c (scm_print_struct): New function to print a structure.
4605 Include "genio.h" to support it. This function doesn't do
4606 anything interesting right now, but I think it should be here
4608 * struct.h: Include "print.h" and add prototype for
4610 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4611 print structures ourself.
4613 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4615 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
4616 before applying the handler in case it doesn't return.
4618 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
4620 * scmsigs.h, async.h: updated.
4622 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
4625 * posix.c (scm_uname): interpret only negative values as an error.
4626 Solaris normally returns a positive value.
4628 * script.c (scm_compile_shell_switches): if we are not going into
4629 an interactive repl, set scm_mask_ints to zero so that asyncs can
4632 * simpos.c (scm_system): don't ignore/unignore signals around
4635 * posix.c (scm_open_pipe): don't ignore/unignore signals around
4638 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
4639 done in boot-9.scm instead.
4641 * scmsigs.c, async.c: Major rewriting of signal handling code.
4642 (scm_sigaction): new procedure.
4643 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
4645 (scm_raise): return unspecified, throw error on failure.
4647 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4649 * regex-posix.c (scm_init_regex_posix): Register the "regex"
4650 feature, to help boot-9.scm decide whether to import the regex
4653 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
4655 * eval.c: Include scmconfig.h at the beginning of the file so that
4656 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
4659 * regex-posix.c: #include "_scm.h" before conditionally #including
4660 <regex.h>; the former defines HAVE_REGCOMP.
4662 * regex-posix.c: #include <regex.h> conditionally, so the file is
4663 CPP'able (for dependency scanning) even on systems that don't have
4666 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4668 Add new R4RS-compliant syntax for keywords.
4669 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
4670 regardless of the setting of the `keywords' read option.
4671 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
4672 can be re-read no matter what the setting of the `keywords' read
4675 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
4677 Add support for POSIX regular expressions.
4679 * regex-posix.c, regex-posix.h: New files. (Some code
4680 is taken liberally from rx/rgx.c in the old Guile dist.)
4682 * init.c: Include regex-posix.h.
4683 (scm_boot_guile_1): Call scm_init_regex_posix.
4685 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
4686 Add regex-posix.[ch] sources.
4687 * Makefile.in: Regenerated.
4689 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
4690 to do this automatically? It didn't for me, bleh.)
4692 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
4694 * fports.c (print_pipe_port): New function.
4695 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
4696 latter doesn't even take the right arguments.
4698 * Makefile.am: Increment shared lib revision number. I think
4699 sometimes the uninstalled Guile finds the installed shared lib;
4700 Gord says doing this might help. As things turned out, I can't
4701 say whether it does.
4702 * Makefile.in: Regenerated.
4704 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
4705 passing it as the closure argument to scm_boot_guile. (Bill
4708 * ports.c (print_void_port, putc_void_port, puts_void_port,
4709 write_void_port, flush_void_port, getc_void_port, close_void_port,
4710 noop0): Use ANSI prototypes instead of K&R declarations, so the
4711 initialization of void_port_ptob gets aggressively type-checked.
4712 Fix arguments of print_void_port and write_void_port. (Bill

4746 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
4748 * script.c (scm_find_executable): Use prototype-style definition
4749 here; apparently it's not quite right to have const in a prototype
4750 and then use a K&R declaration. I wonder if stuff like this will
4751 go away if we compile with -Wrequire-prototypes, or whatever that
4752 is... (Bernard URBAN)
4754 * scmhob.h: New text from Bernard URBAN.
4756 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4758 * script.c: Don't #define const on hpux. Configure takes care of
4759 this. (Thanks to Larry Schwimmer.)
4761 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
4762 decide whether to #include <unistd.h>, instead of listing a bunch
4763 of systems. Don't #include stdio twice. Removed dyked-out
4764 definition of scm_find_impl_file.
4766 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4768 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
4769 library version info to 1:0.

4777 throw.c: Update copyright years; these files have been worked on
4778 significantly in 1997, but only had copyright years for 1996.
4779 Also, change name of copyright holder on some from Mikael
4780 Djurfeldt to Free Software Foundation; he has signed papers
4781 assigning the changes to the FSF.
4783 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
4784 reason not to give the user the option.
4786 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
4787 Return #f on end-of-file when scanning table (i.e. when called
4788 with no arguments). Try to catch errors, when we can.
4789 * posix.c (scm_getgrgid, scm_getpwuid): Same.
4791 * script.h (scm_shell_usage, scm_compile_shell_switches): New
4792 external declarations. These are useful.
4794 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
4796 * posix.c: don't include <sys/select.h> or define macros for
4797 select, since they were not used in this file.
4799 * filesys.c (scm_select): make the fifth parameter microseconds,
4800 not milliseconds. let the fourth parameter be either a real value
4801 or an integer or #f. The first, second and third arguments can
4802 now be vectors: the type of the corresponding return set will be
4804 (set_element, get_element): new static procedures.
4806 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
4808 * strports.c (scm_eval_string): New function.

4811 * strports.h (scm_eval_string): New extern decl.
4813 * net_db.c (h_errno): Add extern decl for this.
4815 * fports.c (local_pclose): New function.
4816 (scm_pipob): Use it in the initializer here.
4819 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
4820 Use a meaningful error message when signalling an error. For
4821 this, scm_gethost must check h_errno rather than errno.
4823 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
4825 * Makefile.in: Regenerated, using automake-1.1p.
4827 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
4829 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
4830 not SCM_UNSPECIFIED.
4832 * script.c (scm_compile_shell_switches): don't append (quit) if
4834 (scm_shell): call scm_exit_status and exit on the result of the
4837 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
4839 Ensure that shared substrings are handled properly when passed to
4840 a system call or other foreign function. Many thanks to Tim
4842 * symbols.h (SCM_COERCE_SUBSTR): new macro.
4843 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
4844 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
4845 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

4860 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
4862 * error.c (scm_error): Add newline to error message.
4864 * init.c (scm_init_standard_ports): Doc fix.
4866 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4868 * dynl-shl.c: Completely replaced with new code from Bernard
4871 * script.c (scm_ice_9_already_loaded): New variable.
4872 (scm_compile_shell_switches): Use it.
4874 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4876 * filesys.c (scm_input_waiting_p): add missing third argument to
4879 * stime.c (scm_localtime): copy the result of localtime before
4880 calling gmtime in case they share a buffer.
4881 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
4884 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
4886 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
4888 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
4890 * Makefile.am (check-local): New target, which causes 'make check'
4891 to run gh_test_c and gh_test_repl, with some trivial input.
4892 * Makefile.in: Rgnrtd.
4894 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
4896 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
4899 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
4901 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
4902 sure how this was supposed to work.
4903 (scm_async_click): don't send SCM_TICK_SIGNAL.
4904 (scm_init_async): don't initialize %tick-thunk.
4906 * the following change doesn't affect the Scheme interface:
4907 gc-thunk is called at the end of garbage collection. however it's
4908 no longer implemented by pretending it's a signal.
4910 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
4911 system async corresponding to scm_gc_thunk.
4912 * async.h: declare scm_gc_async.
4913 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
4914 gc-thunk directly, instead of going through a signal handler.
4915 (scm_gc_async): new variable, points to the GC system-async.
4916 (scm_init_async): save the GC async as scm_gc_async instead
4917 of using system_signal_asyncs.
4918 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
4920 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>
4922 * Makefile.am (libpath.h, cpp_err_symbols.c, cpp_sig_symbols.c):
4923 Don't screw up if we're interrupted.
4924 * Makefile.in: Regeneradet.
4926 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
4928 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
4930 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
4931 we're not using AM_INIT_GUILE_MODULE any more.
4932 * Makefile.in: Reneregated.
4934 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4936 Functions for finding variable bindings, grace à Tim Pierce.
4937 * gh_data.c (gh_lookup, gh_module_lookup): New functions.
4938 * gh.h (gh_lookup, gh_module_lookup): New prototypes.
4940 Get 'make dist' to work again.
4941 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
4942 * Makefile.in: Regenerated, like a surry without a fringe on top.
4944 Changes for reduced Guile distribution: one configure script,
4946 * configure.in, configure: Removed.
4947 * acconfig.h, acinclude.m4: Moved to parent directory, where the
4948 real configure script lives.
4949 * Makefile.in, scmconfig.h.in: Regenerated.
4951 * init.c: #include "script.h", to get prototype for script.c's
4954 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
4956 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
4957 scm_must_malloc, not raw malloc.
4959 * script.c (scm_compile_shell_switches): Dyke out debugging output
4962 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4964 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
4966 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
4967 system has them. Hope this is safe. Previously
4968 sys/timeb.h was included if HAVE_FTIME was defined or if
4969 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
4970 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
4972 * ioext.c (scm_setfileno): add missing third argument to
4973 scm_misc_error call.
4975 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
4977 * eq.c (scm_equal_p): Correctly compare strings of different
4978 varieties. (Thanks to Tim Pierce.)
4980 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
4982 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
4983 #! block comment must occur on a line all by itself.
4985 Move most of the guts of shell command processing into libguile,
4986 so guile.c can be very small (and eventuallly auto-generated. (I
4987 mean, generated mechanically, not self-generated. Hmm.))
4988 * guile.c, script.c, script.h: New source files.
4989 * init.c (scm_boot_guile_1): Call scm_init_script.
4990 * libguile.h: #include "script.h".
4991 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
4992 targets, for new executable.
4993 (libguile_la_SOURCES): Mention script.c.
4994 (modinclude_HEADERS): Add script.h.
4995 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
4996 not dynamic linking is enabled. This is because we're generating
4997 executables now. Move CY_AC_WITH_THREADS call after those, so the
4998 values of cy_cv_threads_libs captures the libs chosen above.
4999 * Makefile.in, configure, aclocal.m4: Regenerated.
5001 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
5002 We don't maintain this interface any more, and it just confuses
5005 * alloca.c: #include <scmconfig.h>, not <config.h>.
5006 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
5007 it'll get included in disties.
5009 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
5011 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
5012 be distributed, because they confuse people.
5013 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
5015 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
5017 * configure.in: check for presence of gethostent (not present on
5018 OpenBSD by default).
5019 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
5020 * configure, scmconfig.h.in: Regenerated.
5022 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5024 * backtrace.c (scm_backtrace): Split message string across
5025 newlines properly. GCC is more tolerant of this than other
5028 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
5030 Merge threads directory into libguile.
5031 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5032 threads.h: New source files.
5033 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
5034 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
5036 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5037 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5038 coop-threads.c.cygnus, coop-threads.h.cygnus.
5039 * configure.in: If we're using threads, include threads.o in
5041 * _scm.h, libguile.h: threads.h lives in this directory now.
5042 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5043 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5044 currently used, but brought along for information's sake.
5045 * ChangeLog-threads: log from old 'threads' directory.
5046 * Makefile.in, configure: Rebuilt.
5048 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5050 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5053 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5055 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5057 Merge GH interface library into libguile.
5058 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
5059 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5060 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5061 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5063 (EXTRA_libguile_la_SOURCES): ... here.
5064 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5065 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5066 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5067 New variables, describing how to build the gh test programs.
5068 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5069 build the test programs, and we probably should have been linking
5070 libguile.la against them all along, to support AIX shared libs.
5071 Add cflags for threads to CFLAGS; add libs for threads to new
5072 variable THREAD_LIBS, used in Makefile.am.
5073 * ChangeLog-gh: log from old `gh' subdirectory.
5074 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5076 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5078 * acconfig.h: Undo change of Apr 9; including the definition of
5079 PACKAGE in the guile headers conflicts with applications' own
5081 * scmconfig.h.in: Regenerated.
5083 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

5090 when PROC is receiving no arguments.
5092 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5094 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5095 have S_IFSOCK. This is the case under Ultrix.
5097 * posix.c (scm_status_exit_val, scm_status_exit_val,
5098 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5099 Ultrix versions of WIFSTOPPED, etc., which assume that their
5100 arguments are lvalues (hmm).
5102 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5104 * eval.c: Doc fixes.
5106 * throw.c: Doc fixes; rearranged.
5108 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
5110 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
5112 * acconfig.h: Added entry for PACKAGE.
5113 * scmconfig.h.in: Regenerated.
5115 Changes to work with automake-1.1n, which has better libtool support.
5116 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5117 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5119 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5121 * Makefile.in: Rebuild.
5123 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5125 * stime.c (scm_mktime): take an optional zone argument.
5126 (scm_localtime): check putenv return value.
5127 (scm_strftime, scm_strptime): moved from posix.c. move #include
5129 stime.h, posix.h: update prototypes.
5130 (bdtime2c, setzone, restorezone): new static procedures.
5131 (scm_mktime, scm_strftime): use them.
5132 (scm_strftime): don't call mktime before strftime. Use
5133 filltime for return value.
5134 (filltime): convert NULL zname to #f.
5135 (scm_strptime): return a count of characters consumed, not
5136 the remaining string.
5138 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5140 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
5141 (scm_mktime): likewise.
5143 Uncomment localtime and mktime.
5145 * configure.in: add AC_STRUCT_TIMEZONE.
5147 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5149 * stime.c (scm_init_stime): don't define ticks/sec.
5150 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5151 return value problem and is still portable.)
5153 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5155 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5156 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5157 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5158 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5159 cpp_err_symbols.c): Corresponding changes.
5160 * Makefile.in: Regenerated.
5162 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5164 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5165 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5166 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5167 * putenv.c: new file, from sh-utils 1.12.
5169 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5170 since allocation isn't for Scheme objects.
5171 (scm_putenv): copy strings before placing in the environment.
5173 * stime.c (scm_current_time): throw an error if time returns -1,
5174 instead of returning #f.
5175 (scm_get_internal_real_time, scm_get_internal_real_time): use
5176 scm_long2num for return value instead of SCM_MAKINUM.
5178 * stime.h: prototypes updated.
5180 * stime.c (scm_time_in_msec): apparently unused, deleted.
5182 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5184 * configure.in: check for gettimeofday.
5186 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5187 which may be more usefully portable than a gettimeofday interface.
5189 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5191 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5193 * Makefile.in: Regenerated.
5195 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5197 * stime.c (filltime): recovered static procedure.
5198 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5201 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5202 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5204 * posix.c (scm_mknod): split the mode argument into type and perms
5205 arguments, like the extra fields returned by stat.
5207 * fports.c (scm_pipob): set the close, free and print procedures.
5208 (scm_close_pipe): new procedure.
5210 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5211 define them in boot-9.scm
5213 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5215 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5216 wan't defined. Don't include fd.h.
5218 * Previously fd.h was regenerated whenever configure was run,
5219 forcing a couple of files to be recompiled.
5221 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5222 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5223 Check for _fileno as well as _file.
5225 * ioext.c: don't fd.h.
5226 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5229 * Change the stratigy for getting information about errno
5230 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5231 generating lists of symbols during the build process, which will
5232 not always work, include comprehensive lists in the distribution.
5233 To help keep the lists up to date, the "check_signals" and
5234 "check_errnos" make targets can be used.
5236 * configure.in: don't check for a command to extract errno codes.
5237 * Makefile.am: update file lists, remove errnos.list and errnos.c
5238 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5239 check_errnos targets.
5240 (CLEANFILES): remove errnos.c and errnos.list, add
5241 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5242 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5243 * errnos.default: deleted.
5244 * cpp_signal.c: new file.
5245 * cpp_errno.c: renamed from errnos_get.c.
5246 * cpp_err_symbols, cpp_sig_symbols: new files.
5247 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5248 * error.c (scm_init_error): #include cpp_err_symbols instead of
5250 * posix.c (scm_init_posix): don't intern signal symbols. #include
5253 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5255 * strop.c (scm_i_index): allow the lower bound to be equal to the
5256 length of the string, so a null string doesn't always give an error.
5258 * posix.h: new prototypes.
5259 * posix.c (scm_status_exit_val, scm_status_term_sig,
5260 scm_status_stop_sig): new functions, as in scsh. They break down
5261 process status values as returned by waitpid.
5263 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5265 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5266 configure doesn't know about it.
5268 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5270 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5272 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5273 which defines C variables with global linkage.
5275 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5277 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5280 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5282 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5283 has time to check why this doesn't work well with continuations.
5285 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5287 * Fix shell syntax error; some shells won't tolerate
5288 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5290 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5292 * posix.c (scm_uname): throw an error if uname fails instead
5295 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5297 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
5300 * async.c (scm_ints_disabled): definition moved from error.c.
5302 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5304 * acconfig.h: Removed PACKAGE.
5306 * scmconfig.h.in: Regenerated.
5308 * snarf.h: g++ says it's non-portable not to specify the first
5309 argument in a varargs declaration. I introduced the first
5310 argument by using preprocessor conditionals.
5312 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5314 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5315 (scm_freopen): use RO string macros for filename and modes.
5316 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.
5318 * posix.c (scm_getgrgid): simplify conversion of name to C string.
5319 (scm_mknod): use RO string macros for path.
5321 * socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
5322 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5324 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5325 use SCM_ROSTRINGP and SCM_ROCHARS.
5327 Thu Mar 13 18:31:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5329 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5332 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5333 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5334 support for byte vectors.
5336 * print.c (scm_iprin1): Limit number of vector elements printed
5337 according to pstate->length.
5339 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5341 * backtrace.c (scm_display_error_message): don't segv if message
5344 * error.h: prototype for scm_error_scm.
5346 * error.c (scm_error_scm): new procedure, reimplements scm-error
5347 in C and uses scm_error.
5349 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5351 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5352 pointer to the Scheme variable read-hash-procedures and intern it
5353 in scm_init_read. Modify scm_read_hash_extend and
5354 scm_get_hash_procedure to use the pointer.
5356 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5358 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5359 (SCM_KEYWORD_STYLE): defined.
5361 * read.c (scm_read_opts): add a keywords option. This isn't a
5362 boolean option, in case someone wants to add support for DSSSL
5364 Setup scm_keyword_prefix symbol.
5365 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5367 I've left keyword support disabled by default, since it doesn't
5368 seem to break the module system and it gives R4RS standard behaviour.
5369 It can be reactivated with (read-set! keywords 'prefix).
5371 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5373 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5374 before constructing arbiter.
5376 * eval.c (scm_m_define): Bugfix: Check that the object is a
5377 closure before setting the procedure property!
5379 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5381 * ports.c: Removed `ungetc-char-ready?'.
5383 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5385 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5386 (idea from Mikael: make it a pair so scm_permanent object only
5388 (scm_read_hash_extend): don't call scm_permanent_object.
5389 (ideas from Mikael): if chr is already in the list, replace its
5390 procedure instead of appending it again. If proc is #f, remove
5392 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5394 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5396 * gdbint.c (gdb_read): update scm_lreadr usage.

5407 (scm_read_hash_extend): new procedure.
5408 (scm_get_hash_procedure): new procedure.
5409 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5410 for extended # processing.
5411 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5412 scm_read_token): remove case_i, sharp arguments. Change callers.
5414 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5416 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5417 (SCM_CASE_INSENSITIVE_P): define.
5419 * read.c: add case-insensitive option to scm_read_opts.
5420 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5421 to determine whether to convert symbol case.
5422 (default_case_i): definition removed.
5423 * read.c (scm_read_token): if case_i, downcase ic before doing
5426 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5428 * configure.in: Added configuration option `guile-debug'.
5429 Configure with --enable-guile-debug if you want a bunch of extra
5430 functions used for debugging when developing Guile.
5432 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5434 * procs.c (make-cclo): New undocumented debugging procedure: Make
5435 compiled closure with internal procedure PROC and length LENGTH.
5436 Only compiled if GUILE_DEBUG is defined.
5438 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5440 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5442 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5444 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5445 with 3 or more args internally to the evaluator.
5447 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5449 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5450 with 3 or more args internally to the evaluator. This is mainly
5451 because we don't want to pass entry and exit points of the
5452 debug support twice, but it also seems to increase the speed of
5453 the evaluator for such calls (e. g. (+ 1 2 3)).
5455 * backtrace.c (scm_display_application): New procedure:
5456 display-application; Set fancy printing parameters individually
5457 for different types of display (backtrace, error, application).
5458 (These should of course be customizable!)
5460 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5461 clear the CHECK-flags.
5463 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5465 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5467 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5469 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5470 from pairs with a GLOC in the car.
5472 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5473 otherwise `symbol-hash' will behave badly.
5474 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5475 we get segmentation fault!
5477 * symbols.c: Added #include "weaks.h". New functions:
5478 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5479 moved to an extraneous library when we split libguile.)
5481 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5483 * filesys.c (scm_stat): stat now takes fport arguments too as
5484 documented in the manual.
5486 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5488 * debug.c (scm_single_step): Bugfix: Call continuation with
5489 scm_call_continuation instead of throwing to it.
5491 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5493 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5494 argument wasn't declared to be optional.
5496 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5498 * stime.c (scm_init_stime): Add feature "current-time".
5500 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5502 * throw.h: prototype for scm_exit_status.
5503 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5504 args to derive an exit status. Allows (quit) to work from a
5506 (scm_exit_status): new function.
5509 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5511 * eval.c (scm_deval): Removed some old code.
5512 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5514 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5517 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5520 * procs.c: Introduce the existent C function scm_thunk_p at the
5521 Scheme level as well.
5523 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5525 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5526 used from C to easily lookup the value of a symbol in the current
5529 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5531 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5532 scm_init_unif in this file. This will also fix a previous problem
5535 * configure.in: Added AM_MAINTAINER_MODE
5537 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5539 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5542 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5544 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5545 source files that are not always included in libguile but should
5546 have their dependencies calculated by automake. This variable is
5547 recognized by automake, no further magic is needed.
5548 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5549 to deal exclusively with *.lo files, as it seems. The *.o files
5550 are built automatically when the corresponding *.lo file gets
5553 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5555 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5558 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5560 * unif.c (scm_array_set_x): minor change to argument error checking.
5562 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5564 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5565 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5566 They should only be included in the library at configure.in's
5568 (libguile_la_LDADD): Include the appropriate .lo files here.
5569 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5570 so we know when to build them (and their .lo bretheren).
5571 * configure.in (LIBLOBJS): New substituted variable. We let
5572 configure decide which .o files to include in LIBOBJS, and then
5573 put the corresponding list of .lo files in LIBLOBJS. The latter
5574 is what we pass to libtool.
5575 * Makefile.in, configure: regenerated.
5577 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5579 * symbols.c (scm_sysintern0): New function. Contains the core of
5580 old scm_sysintern but doesn't take a second value argument.
5581 (scm_sysintern): Now uses scm_sysintern0.
5582 (scm_sysintern_no_module_lookup): Renamed to
5583 scm_sysintern0_no_module_lookup and doesn't take a second value
5584 argument any longer.
5586 * symbols.h (scm_sysintern0: Added declaration.
5588 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5589 scm_sysintern when interning option keys. Otherwise we risk
5590 destroying the values of already interned variables.
5592 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5593 scheme-level boolean (use SCM_NFALSEP).
5595 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5597 (scm_backtrace): New function. (C version of old function from
5598 boot-9.scm) Motivation: Make it possible to display backtraces
5599 without depending on boot-9.scm. (I'm uncertain if this
5600 motivation is good enough...)
5602 * root.h (scm_root_state): Add member the_last_stack_var.
5603 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5605 * root.c (mark_root): Mark scm_the_last_stack_var.
5607 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5610 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5612 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5613 1. mark_lazy_catch didn't mark the smob.
5614 2. Both functions above have standard variants:
5615 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5616 free_lazy_catch --> scm_free0.
5618 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5620 * throw.c (scm_internal_lazy_catch): New function.
5621 (scm_lazy_catch): Rewritten to use it.
5622 (scm_ithrow): Handle the new lazy catch representation.
5623 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
5624 that doesn't have a jmpbuf is a lazy catch clause.
5625 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
5626 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
5627 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
5629 (scm_init_throw): Register the new lazy-catch smob type.
5630 * throw.h (scm_internal_lazy_catch): decl for new function.
5632 * throw.c (scm_internal_catch): Doc fixes.
5634 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
5635 configure.in. Including this might cause problems if applications
5636 that link against libguile include their own copies of alloca, but
5637 if they're using autoconf, they should be adding libguile to LIBS
5638 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
5639 the copy in libguile, and things will be okay. (I think.)
5641 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5643 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
5645 strop.h: move prototypes too.
5647 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5649 * posix.c (scm_init_posix): don't intern EINTR since it's now done
5652 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
5653 etc. I deleted them from filesys.c long ago, but didn't
5654 notice they were here too (although ineffective since
5655 sys/stat.h wasn't included).
5657 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
5659 * eval.c: Don't define alloca in GCC case. gcc will automatically
5660 use __builtin_alloca if appropriate.
5662 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5664 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
5665 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
5666 that values of automatic variables are preserved. See comments
5667 for safe_setjmp for details.
5669 Change from Thomas Morgan:
5670 * variable.c: Include eq.h.
5671 (var_equal): New function.
5672 (variable_smob): Use var_equal as the discriminator for variables.
5674 * throw.c (s_throw): Remove extraneous declaration.
5676 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
5677 * eval.c: Add necessary CPP cruft to support that.
5678 * configure, Makefile.in, scmconfig.h.in: regenerated.
5680 Change from Thomas Morgan:
5681 * procprop.c (scm_procedure_properties): Convert the Scheme
5682 boolean returned by scm_procedure_p into a C boolean before using
5683 it as a condition for SCM_ASSERT.
5684 (scm_procedure_property): Likewise.
5686 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
5687 indications of Unixness.
5690 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5692 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
5694 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5696 * read.c (scm_lreadr): use scm_misc_error to improve one of the
5697 "unknown # object" error messages.
5699 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
5700 (scm_i_index) and declare it static. Add a 'direction' argument
5701 to indicate what way the search should go.
5702 (scm_i_index): throw out-of-range error instead of wrong-type-arg
5704 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
5705 strop.h: remove scm_i_index, scm_i_rindex prototypes.
5707 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5709 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
5711 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
5712 to avoid clash with various scsh forks.
5714 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
5716 The following two changes (ramap.c, throw.c) are motivated by the
5717 apparent unportability of forward declarations of static arrays of
5718 the form `static foo bar[];'.
5720 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
5721 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
5723 * throw.c (scm_throw): Moved above scm_ithrow.
5725 * options.h: Removed the extern declarations of scm_yes_sym and
5726 scm_no_sym since these are static.
5728 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5730 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
5732 * Makefile.am: remove AWK=@AWK@.
5733 Add a rule for generating errnos.list.
5734 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
5736 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
5737 don't extract errnos, just set a variable (avoids the
5738 need to recompile error.c just because configure is run.)
5740 * unif.h: update prototypes.
5741 * unif.c (scm_uniform_array_read,write): change the offset and
5742 length arguments to start and end, for consistency.
5744 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
5746 * ioext.h: update prototypes.
5747 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
5748 scm_read_line_x, it's a more general procedure using an
5749 interface from scsh. read-line and read-line! are now defined
5751 Note that the new read-line trims the terminator
5752 by default, previously it was appended to the returned string. An
5753 optional argument specifies how to process the terminator (scsh
5754 compatible). For the old behaviour: (read-line port 'concat).
5755 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
5756 returns a pair, but is converted to multiple values if the scsh
5759 socket.h: update prototypes.
5760 * socket.c (scm_recvfrom): for consistency with other procedures,
5761 take start and end as separate optional arguments.
5762 (scm_recv, scm_recvfrom): don't allow the second argument
5763 to be a size, only a buffer. Change the scheme names to
5764 recv! and recvfrom!. Don't return the buffer.
5766 * ioext.h, posix.h: move prototypes too.
5767 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
5768 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
5769 "read.h" and "unif.h".
5770 * ioext.c: include "chars.h"
5772 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
5774 * dynl.c: The dynamic linking and module registration functions
5775 are now defined even when dynamic linking is not available for the
5776 host system. Some of their functionality can be done without
5777 dynamic linking; when it's really needed, they throw errors.
5779 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
5781 * configure.in: Only define DYNAMIC_LINKING when one of the system
5782 dependent functions is detected.
5783 * dynl.c (scm_dynamic_func): New function to get the address of a
5784 function in a dynamic object.
5785 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
5786 produced by scm_dynamic_func as the thing to call.
5788 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
5790 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
5791 (scm_register_module_xxx, scm_registered_modules,
5792 scm_clear_registered_modules): New functions.
5794 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
5796 * symbols.c (scm_sysintern): Renamed to
5797 scm_sysintern_no_module_lookup.
5798 (scm_sysintern): New function to take the place of the old
5799 scm_sysintern. It uses the current toplevel lookup closure to give
5800 the symbol its value. This is a temporary hack to put packages
5801 like gtcltk into their own module.
5802 (scm_can_use_top_level_lookup_closure_var): New variable to tell
5803 us whether `scm_top_level_lookup_closure_var' has been initialized
5805 * eval.c (scm_init_eval): Set it.
5807 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5809 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
5810 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
5812 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
5814 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
5815 scm_sys_dup): deleted: FD capability will be added to other
5817 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
5818 scm_fd_free, fd_smob, scm_intern_fd.
5819 (scm_open): renamed from scm_sys_open. Return a port instead of
5820 an FD object. Make the mode argument optional.
5821 (scm_sys_create): deleted, it's just a special case of open.
5822 (scm_init_filesys): move interning of constants O_CREAT etc.,
5823 here (were previously using SCM_CONST_LONG macro).
5824 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
5826 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
5827 include "fports.h" and <stdio.h>
5828 (scm_stat, scm_select): don't support FD objects.
5830 * error.h: adjust scm_syserror_msg prototype.
5831 * error.c (scm_syserror_msg): take an extra argument for errno.
5832 Using the global value didn't always work, since it could be
5833 reset by procedure calls in the message or args arguments.
5835 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
5836 I don't understand why the check was there (and what about the
5839 * strop.c (scm_string_copy): allow shared substrings to be copied.
5841 * unif.h: corresponding change to prototypes.
5842 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
5843 recognize two new optional arguments: offset and length. Allow
5844 the port argument to be an integer (file descriptor, for scsh).
5845 Include <unistd.h> for "read" prototype.
5847 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5849 * socket.c: don't include filesys.h.
5851 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
5853 * Makefile.am: add AWK=@AWK@ (?)
5855 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
5857 Add a rule to generate errnos.c from errnos.
5858 * error.c (scm_init_error): include errnos.c.
5859 * errnos_cnvt.awk: new file, converts the list of errno codes to
5861 * errnos_get.c: new file.
5862 * errnos.default: new file, contains errnos to try if they can't
5863 be extracted from errno.h.
5864 * configure.in: if using GCC, try and extract errno codes from
5868 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
5870 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
5871 * Makefile.am: Made libguile into a libtool library.
5872 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
5873 Set libtool_libs to indicate that libguile is a libtool library.
5874 See guile/ChangeLog for details.
5875 * .cvsignore: ignore "*.lo", the libtool library objects.
5877 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5879 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
5880 use htons in getservbyport argument.
5882 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5884 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
5885 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
5888 * objprop.c (scm_object_property): No need to take the CDR of the
5889 value returned by scm_object_properties, since Aug 20 change.
5891 * configure.in: When checking for struct linger, #include
5892 <sys/types.h> as well as <sys/socket.h>. I've never known
5893 <sys/types.h> to cause any portability problems, and Solaris's
5894 <sys/socket.h> needs it.
5895 * configure: Rebuilt.
5897 I think the Sun compiler has chosen a perverse way to interpret
5898 ANSI declarations combined with K&R definitions. We'll
5899 appease it a little bit. But when it invades France, we fight.
5900 * print.c (scm_iprlist): Change 'tlr' argument to an int.
5901 * print.h (scm_iprlist): Here too.
5902 * numbers.c (scm_divbigdig): Change definition to match
5903 declaration in numbers.h.
5904 * unif.c (scm_makflo): Change definition to match declaration in
5907 * init.c (scm_boot_guile): Don't return the value of
5908 scm_boot_guile_1. This function doesn't return a value;
5909 scm_boot_guile_1 doesn't return a value (or return at all).
5911 * eval.c (unmemocopy): Add a semicolon to appease the Sun
5914 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
5915 compile. I have a feeling this function is a bad idea anyway ---
5916 one should always test for features, not systems.
5918 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
5919 semicolons. Only pure luck kept this from being noticed earlier.
5921 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
5923 * socket.c (scm_recvfrom): Added missing semicolon.
5925 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5927 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
5928 the buffer and start and end positions for scsh networking
5931 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
5933 * configure.in: Revert previous change to this file; the problem
5934 is due to transient automake weirdness.
5935 * configure: Rebuilt.
5937 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
5938 PLUGIN/guile.libs. configure generates the latter from the former.
5939 * Makefile.in: Rebuilt.
5941 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
5942 need this if we install scripts, like guile-snarf.
5943 * configure: Rebuilt.
5945 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5947 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
5949 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
5951 * socket.c (scm_addr_vector): fix faulty scm_listify.
5953 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
5955 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
5956 style block comment is no longer considered an error.
5958 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
5960 * PLUGIN/guile.libs.in: New file.
5961 * PLUGIN/guile.libs: Removed from repository.
5962 * configure.in: Create PLUGIN/guile.libs from
5963 PLUGIN/guile.libs.in. This is for including additonal libraries
5964 needed for dynamic linking.
5965 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
5966 instead of PLUGIN/guile.libs.
5968 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
5970 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
5972 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
5973 occurrences of the given element from the list, not just the
5974 first. This is how the Emacs Lisp functions behave, how the
5975 analogous Common Lisp functions behave, and (I believe) how the
5976 older Maclisp functions worked. I realize that this change may
5977 break code, but it seemed better to break it before the Guile
5980 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
5981 Their prototypes were already present in gc.h, but they weren't
5983 (scm_init_storage): Initialize scm_protects.
5984 * root.c (scm_protects): New element of scm_sys_protects.
5986 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
5988 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
5990 * libguile.h: Added #include "libguile/net_db.h".
5992 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
5993 30 change. That file is only meant for communication between the
5994 configuration process and load.c. If code linked against libguile
5995 wants to get at the paths mentioned in libpath.h, it can call
5996 functions declared in load.h.
5998 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6000 * libguile.h: Removed #include "libguile/fdsocket.h"
6002 * net_db.c: Added #include <sys/socket.h>.
6004 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
6006 * filesys.c (scm_input_waiting_p): use select in preference to
6007 FIONREAD, since the latter doesn't detect EOF.
6008 Throw error if neither select nor FIONREAD available.
6010 * socket.c (scm_connect): take a port, not a fd object.
6011 (scm_fill_sockaddr): throw an error if fam is not recognised.
6012 (scm_bind): use scm_fill_sockaddr.
6013 (scm_listen): take a port, not a fd object.
6014 (scm_accept): take and return a port. return #f in the car if
6015 address can't be got
6016 (scm_sock_fd_to_port): new procedure.
6017 (scm_socket): use scm_sock_fd_to_port.
6018 (scm_addr_vector): throw error if unrecognised address type.
6019 take an extra argument with the calling procedure name.
6020 (scm_getsockname): take a port. return #f if address can't be got.
6021 (scm_getpeername): take a port. return #f if address can't be got.
6022 (scm_recvfrom): take a port. return #f for address component if can't
6024 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6025 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6027 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6029 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6030 use separate data pointers, to allow them to be designed
6031 independently and reused.
6032 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6033 Renamed from catch_body, catch_handler, and uncaught_throw; made
6035 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6037 (scm_catch): Use the above.
6038 (scm_throw): Don't bother printing a message for an uncaught
6039 throw; we establish a default handler in init.
6040 * throw.h (scm_internal_catch): Prototype updated.
6041 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6043 (struct scm_body_thunk_data): New structure, used as data
6044 argument to scm_body_thunk.
6045 * init.c (struct main_func_closure): New structure, packaging up
6046 the data to pass to the user's main function.
6047 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6048 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6049 scm_internal_catch to establish a catch-all handler, using
6050 scm_handle_by_message. This replaces the special-case code in
6052 (invoke_main_func): Body function for scm_internal_catch; invoke
6053 the user's main function, using the main_func_closure pointer to
6054 decide what to pass it.
6055 * root.c (struct cwdr_body_data): Remove handler_proc member.
6056 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6057 (cwdr_handler): Removed.
6059 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6061 * socket.h (SCM_P): update bind prototype.
6062 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6063 include "feature.h".
6064 (scm_socket): return a port, not a file descriptor object.
6065 include "fports.h" and <unistd.h>
6066 (scm_bind): take a port, not a file descriptor object.
6067 take an extra argument for address args.
6069 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6070 INADDR_NONE, INADDR_LOOPBACK.
6072 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6074 * init.c: include net_db.h and not fdsocket.h.
6075 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6077 * Makefile.am: corresponding changes.
6078 * socket.h: renamed from fdsocket.h, fix names.
6079 * net_db.h: renamed from socket.h, fix names.
6080 * socket.c: renamed from fdsocket.c.
6081 remove _sys from procedure names.
6082 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6083 add "socket" to features list.
6084 * net_db.c: renamed from socket.c.
6085 remove _sys from procedure names.
6086 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6087 add "net-db" to features list.
6088 include "net_db.h". don't include <sys/socket.h> or
6091 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6093 * tags.h (scm_tags): Removed comma at end of last enumerator.
6095 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6097 Don't use GCC extensions to allocate space for debugging frames.
6098 (Here he goes again! Why do we put up with this?!)
6099 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6100 an scm_debug_info structure, not an in-line array of them. Add
6101 'info' member, to say how many vect elements we've used, for eval
6103 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6104 a new variable debug_info_end to mark the end of vect, instead of
6105 the address of the 'info' pointer itself.
6106 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6107 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6108 (SCM_APPLY): Explicitly allocate space for debug.vect.
6109 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6110 * stacks.c: Adjusted for new debug frame structure.
6111 (RELOC_INFO, RELOC_FRAME): New macros.
6112 (stack_depth, read_frames): Use them, and new scm_debug_frame
6113 element 'info', instead of magically knowing that eval frames have
6114 an info pointer sitting after vect.
6115 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6117 (scm_init_stacks): Formatting tweaks.
6119 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6121 Give GCC more control flow information, so it can be sure that
6122 variables aren't used uninitialized.
6123 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6124 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6125 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6126 scm_misc_error): Tell GCC that these functions never return.
6127 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6128 out the field type, call abort if SCM_ASSERT returns, to placate
6130 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6131 scm_wta ever returns. We can't handle this case anyway, and this
6132 gives the optimizer more information.
6133 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6134 scm_wta ever returns.
6136 In some cases, the code is fine, but GCC isn't smart enough to
6137 figure that out; this usually happens when one variable is only
6138 initialized and used when a particular condition holds true, and
6139 we know that condition will never change within a given invocation
6140 of the function. In this case, we simply initialize the variables
6141 to placate the compiler, hopefully to a value which will cause a
6142 crash if it is ever actually used.
6143 * print.c (scm_iprin1): Initialize mw_pos.
6144 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6145 * throw.c (scm_ithrow): Initialize dynpair.
6146 * unif.c (scm_uniform_vector_ref): Initialize cra.
6147 * struct.c (init_struct): Initialize prot.
6148 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6150 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6151 if EXPR contains no expressions.
6153 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6155 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6156 cause an infinite loop (???). So much for the algebraic
6157 equivalency of variable-sized arrays and alloca...
6159 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6161 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6162 a SCM boolean, not a C boolean.
6164 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6166 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6167 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6168 rules for raising scm_mtrigger. Previously, unfortunate but not
6169 unlikely circumstances could result in almost constant invokation
6170 of the gc. Now, this situations should be less likely, but they
6171 are not prevented completely.
6173 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6175 * numbers.c (scm_fuck): Procedure removed; looks like old test
6177 * numbers.h: Prototype removed.
6179 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6181 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6182 array to a pointer, to match my Nov 21 change in eval.c.
6184 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6186 * libguile.h: Added #include "libguile/backtrace.h", #include
6187 "libguile/stacks.h".
6189 * strings.c (scm_string scm_make_string scm_string_ref
6190 scm_string_set_x scm_string_equal_p scm_string_append):
6191 Bugfix according to scm patch from Aubrey Jaffer:
6192 Corrected long-standing
6193 (not (eqv? (integer->char 128)
6194 (string-ref (make-string 1 (integer->char 128)) 0)))
6195 bug found by John Kozak <jk@noontide.demon.co.uk>.
6197 * strports.c, strports.h: Make scm_eval_0str return the value of
6198 the last expression evaluated (previously, it returned void).
6200 * strports.c, strports.h: New function: scm_read_0str. Does what
6203 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6205 * simpos.c (scm_getenv): return #f if string can't be found in the
6206 environment instead of throwing an exception, for compatibility
6207 with numerous other systems.
6209 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6211 * Makefile.am (.c.x): Use guile-snarf.
6212 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6214 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6216 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6218 * backtrace.c (scm_display_error_message): Made non-static, and
6219 renamed from display_error_message.
6220 * backtrace.h (scm_display_error_message): Added extern decl.
6221 * throw.c (uncaught_throw): Use it to display the error message.
6223 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6225 * inet_aton.c: Use #if 0, not #ifdef 0.
6227 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6229 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6230 to convert the returned value.
6231 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6232 the offset argument.
6234 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6236 Add new interface to catch/throw, usable from C as well as
6238 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6239 (scm_internal_catch): New function, replaces...
6240 (scm_catch_apply): Deleted.
6241 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6242 mechanism which is a bit more code, but can be used nicely from C
6243 and implement the Scheme semantics as well.
6244 (scm_internal_catch): This is the replacement; it's named after
6245 the analogous function in Emacs.
6246 (scm_catch): Reimplemented in terms of the above.
6247 (struct catch_body_data, catch_body, catch_handler): New
6248 functions, used by scm_catch.
6249 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6250 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6251 support for new cwdr.
6253 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6256 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6258 * acconfig.h: Added DYNAMIC_LINKING symbol.
6259 * configure.in: Add option and checks for dynamic linking.
6260 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6261 dynl.h: New files for dynamic linking support.
6262 * Makefile.am (libguile_a_SOURCES):
6264 (modinclude_HEADERS): Added "dynl.h".
6265 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6267 * init.c (scm_boot_guile_1): Call
6268 scm_init_dynamic_linking to initialize dynamic linking support.
6270 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6272 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6273 (as we Schemers say). It needs to be global, so that I can tweak
6274 it for the proper operation of unexec.
6275 (scm_boot_guile_1_live): New variable, see above.
6277 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6279 * guile-snarf.sh: Removed.
6280 * PLUGIN/guile.libs: Added dependency for -lm.
6281 * acinclude.m4: Renamed from aclocal.m4.
6282 * PLUGIN/greet: Removed.
6283 * Makefile.am, aclocal.m4: New files.
6284 * configure.in: Updated for Automake.
6286 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6288 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6289 and not top_level_lookup_thunk_var.
6291 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6293 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6295 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6297 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6298 Scheme function, instead of syntax. Single argument is now a
6301 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6303 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6304 scm_ra_divide): Properly terminate statements passed as arguments
6305 to IVDEP macros. (Thanks to Bernard Urban.)
6307 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6308 with non-constant sizes. (Thanks to Bernard Urban.)
6310 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6312 It's an "eval closure", not an "eval thunk." A thunk is a
6313 function of no arguments.
6314 * root.h (struct scm_root_state): Renamed
6315 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6316 (scm_top_level_lookup_closure_var): Renamed from
6317 scm_top_level_lookup_thunk_var.
6318 * root.c (mark_root): Uses changed.
6319 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6320 * init.c (scm_start_stack): Uses changed.
6321 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6322 Change scheme-visible name to *top-level-lookup-closure* from
6323 *top-level-lookup-thunk*.
6325 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6327 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6328 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6330 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6332 * gc.c (struct scm_heap_seg_data): Doc fixes.
6334 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6335 sweeping. Then, prepend each segment's free cells to its
6336 freelist, rather than wiping out the old value. (Thanks to Marius
6339 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6340 scm_check_freelist, scm_debug_newcell): New functions and
6341 variables, for debugging freelist problems.
6342 * pairs.h (SCM_NEWCELL): New debugging version added.
6343 * gc.h (scm_debug_newcell): Added extern declaration, used by
6344 debugging version of SCM_NEWCELL.
6346 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6348 On some systems <libc.h> conflicts with <unistd.h>, and should not
6349 be #included at all.
6350 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6351 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6352 * configure.in: Call it.
6353 * posix.c, filesys.c: Use its results to decide whether or not to
6355 * configure, scmconfig.h.in: Rebuilt with autoconf and
6358 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6360 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6361 pointer to the stdio stream before calling scm_setbuf0, so the
6362 latter will be able to retrieve it. I'm surprised this didn't
6363 segfault earlier. (Thanks to Christopher Lee.)
6365 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6367 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6370 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6372 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6373 number of stack narrowing specifier pairs. The first specifier in
6374 a pair controls inner border, the second the outer border. A
6375 number means cut that number of frames, a procedure object means
6376 cut until that object is found in operator position in a frame.
6378 * root.c (cwdr): Bugfix.
6380 * read.c: Recording of positions disabled by default.
6382 * procs.c (scm_closure_p): New function.
6384 * posix.c (scm_tmpnam): New function.
6386 * load.c: Added #include "throw.h".
6387 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6390 * load.c, load.h (scm_read_and_eval_x): New function.
6392 * eval.c: Renamed debug option "deval" to "debug".
6394 (scm_eval_x): `eval!' is no longer accessible from the scheme
6395 level. Motivation: We can't allow operations which introduce
6396 glocs into the scheme level. Guile's type system can't handle
6397 these as data. Use `eval' or `read-and-eval!' as replacement.
6399 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6400 SCM_CONSP since this is a macro!; Set vframe.prev to
6401 scm_last_debug_frame instead of 0. In this way we can look
6402 "above" the virtual start stack frame if we wish.
6403 (scm_debug_hang): New function: Useful for debugging Guile in
6404 certain tricky situations. Will probably be removed later...
6406 * debug.h: Changed semantics of debug option "backtrace". This
6407 option now only indicates whether we want automatic backtrace at
6410 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6412 * ports.c: #include "filesys.h"
6413 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6415 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6416 Motivation: This is system specific code which is related to file
6417 I/O. It also may use select. Added code by Gary Houston to
6418 detect presence of character in stdio buffers.
6420 * libguile.h: #include "libguile/libpath.h"
6422 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6423 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6424 SCM_SITE_DIR; Install libpath.h among the other include files.
6426 * load.c, load.h (scm_sys_package_data_dir): New function.
6428 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6430 * stacks.h: Bugfix: Don't use tail-array length field as stack
6431 length field! This screwed GC.
6433 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6435 * _scm.h: Added #ifndef around definition of macros min and max.
6437 * __scm.h: Added hooks for threads to plugin to in ints protection
6438 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6439 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6440 the main code in these macros duplicated and spread over multiple
6441 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6442 SCM_THREAD_SWITCHING_CODE.
6444 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6446 * snarf.h: New file.
6447 * guile-snarf.sh: New file.
6448 * Makefile.in (inner_h_files): Added snarf.h
6449 (ancillary, install, uninstall, distclean): Added actions for
6451 (.c.x): Use guile-snarf.
6452 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6453 (gen_c_files): Note that these depend on guile-snarf.
6454 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6455 now in "snarf.h". Added #include "snarf.h" to get them.
6456 * libguile.h: Added #include "snarf.h".
6457 (Patches applied and tweaked by Jim Blandy.)
6459 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6461 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6462 standards suggest against providing prototypes for system
6463 functions. Thanks to Greg Troxel.
6465 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6467 * strports.c (scm_eval_0str): New function.
6468 #include "read.h", to get prototype for scm_read.
6469 * Makefile.in (strports.o): Update dependencies.
6470 * strports.h: New prototype.
6472 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6473 scheme name from "int?" to "integer?". It seems to do the job.
6474 * numbers.h: Rename prototype too.
6475 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6478 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6479 scm_num_eq_p): Rename these according to R4RS conventions: call
6480 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6481 to making libguile R4RS compliant without ice-9...
6483 * load.c (scm_sys_search_load_path): Search for files under all
6484 extensions listed in the %load-extensions variable. If FILENAME
6485 is absolute, return it unchanged, without searching the load path.
6486 (scm_loc_load_extensions): New variable, pointing to
6487 %load-extensions' value cell.
6488 (scm_init_load): Initialize it, and the value it points to.
6489 (scm_primitive_load_path): Improve error reporting.
6491 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6492 of new Scheme variable %load-hook.
6493 (scm_primitive_load): Apply %load-hook to filename.
6495 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6497 * configure.in: add tests for figuring out whether buffered data
6498 is available in a FILE structure, which is needed by char-ready.
6500 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6503 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6504 exceptions using misc_error instead of syserror. It seems a bit
6505 odd to throw an exception if a string can't be found in the
6506 environment, but it's consistent with open-file, stat etc.
6507 (simpos.h): remove sys_ from getenv.
6509 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6510 occurs, throw an error instead of returning errno. Return value
6512 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6514 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6516 * filesys.c (scm_stat2scm): derive file type and permissions from
6517 the stat mode and append them to the returned vector.
6518 There isn't much overhead in doing this and it avoids the need to
6519 work with S_IRUSR et al. in Scheme.
6520 Define symbols scm_sym_regular etc.
6521 (scm_init_filesys): don't intern S_IRUSR etc.
6523 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6524 and s_primitive_load_path.
6526 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6528 * error.h: don't declare error symbols. prototype for scm_misc_error.
6530 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6533 * error.c: use SCM_SYMBOL to set up error keys.
6534 scm_misc_error: new procedure.
6536 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6538 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6539 between `#!' and `!#' is ignored.
6540 (skip_scsh_block_comment): New function.
6542 * feature.c (scm_set_program_arguments): New argument, FIRST.
6543 * feature.h: Update prototype.
6544 * init.c (scm_boot_guile_1): Pass new argument to
6545 scm_set_program_arguments.
6547 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6549 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6550 (scm_boot_guile): Call scm_set_program_arguments here, later than
6551 the old initialization.
6553 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6554 initialization procedure.
6555 - Delete in, out, err arguments; there are other perfectly good
6556 ways to override these when desired.
6557 - Delete result argument; this function shouldn't ever return.
6558 - Rename init_func argument to main_func, for less confusion.
6559 - Delete boot_cmd argument; main_func is more general.
6560 -Add 'closure' argument, to help people pass data to main_func
6561 without resorting to global variables.
6562 - Abort if reentered; don't bother returning an error code.
6563 - Call scm_init_standard_ports to set up the default/current
6564 standard ports; no need to pass them to scm_start_stack.
6565 - Remove code to evaluate the boot_cmd, and start the repl; let
6566 the user do something like that in main_func if they want.
6567 - Remove code to package up a return value; main_func can do any
6569 - Call exit (0), instead of returning.
6570 (scm_start_stack): Don't initialize the I/O ports here; that's
6571 weird. Delete in, out, err arguments. Move guts to
6572 scm_init_standard_ports, scm_stdio_to_port.
6573 (scm_init_standard_ports): New function, to set up current and
6574 default standard ports.
6575 (scm_start_stack, scm_restart_stack): Make these static.
6576 * init.h (scm_boot_guile): Adjust declaration.
6577 (scm_start_stack, scm_restart_stack): Remove externally
6578 visible declarations for these.
6579 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6581 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6582 written out several times in scm_start_stack.
6583 * fports.h: New declaration for the above.
6585 * feature.c (scm_set_program_arguments): New function.
6586 * feature.h: New declaration for the above.
6588 * ports.c: Formatting tweak.
6590 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6592 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6593 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6594 for obtaining the address of a car or cdr field. Motivation:
6595 &SCM_CXR make assumptions about the internal structure of the
6598 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6599 Motivation: see SCM_CXRLOC.
6601 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6602 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6603 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6604 Motivation: Safer use. Some other macros are defined in terms of
6605 these operations. If these are defined using the SCM_SETCXR
6606 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6607 to inefficiency and an <e1> with side-effects could potentially
6608 break. Also, these particular operations are heavily utilized in
6609 the garbage collector. In unoptimized code there will be a
6612 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6613 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6614 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
6615 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
6616 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
6617 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6618 vports.c: Cleaned up use of pairs: Don't make any special
6619 assumptions about the internal structure of selectors and
6620 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6621 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
6622 (Among other things, this change makes it easier to build Guile
6623 with certain compilers which have problems with casted lvalues.)
6625 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6627 * stacks.c: Improve selection of relevant stack frames when making
6628 a stack object. Introduce one level of indirection in the stack
6629 object to make it possible to "narrow" to a certain region of the
6630 stack. This facilitates making use of more clever algorithms (not
6631 implemented) for selecting relevant frames and gives a cleaner
6632 design since selection of frames can be done independently of
6633 extraction of frames from the real stack.
6634 (scm_stack_id): Also take #t as argument which means look at
6637 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
6638 Turn n_tail into an integer directly representing current number
6639 of frames in stack. Add field tail.
6641 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
6643 * debug.c (scm_make_memoized): Made it available at scheme level.
6644 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
6645 SCM_NIMP before applying heavier predicates in argument checking.
6646 (scm_local_eval): Also take memoized object as argument.
6648 * backtrace.c (scm_display_error): Just a safety measure: Stacks
6649 aren't created with zero length, but should such a strange
6650 creature suddenly turn up...
6652 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
6654 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
6655 `del', for the sake of C++ compilers. (Patch applied by JimB.)
6657 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
6659 * variable.c (scm_make_variable): Make the name hint optional, as
6661 (anonymous_variable_sym): Renamed from variable_sym. All uses
6664 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
6665 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
6666 of scm_primitive_load_path was also changed to
6667 "primitive-load-path", from "%try-load-path". Callers changed.
6668 We'd like to respect the convention that a function named
6669 "try-mumble" should behave just like the function called "mumble",
6670 but return #f instead of signalling some error.
6671 * load.h: Rename prototypes.
6673 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6675 * print.c (make_print_state, grow_print_state), print.h: Modified
6676 the print state representation: Don't use a tail array for
6677 recording of circular references. Resizing of the print state
6678 structure invalidates the print state pointer. To avoid passing
6679 around an indirect print state reference to all printing
6680 functions, we instead let the print state reference a resizable
6683 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
6685 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
6686 Don't crash when passed an improper list terminated by a
6687 non-immediate value.
6689 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
6691 Allocate data for structures on an eight-byte boundary, as
6692 required by the tagging system.
6693 * struct.c (alloc_struct): New function.
6694 (scm_make_struct, scm_make_vtable_vtable): Call it.
6695 * struct.h (scm_struct_n_extra_words): Bump to 3.
6696 (scm_struct_i_ptr): New "field".
6697 * gc.c (scm_gc_sweep): When we need to free the data, use the
6698 information stored by alloc_struct to find the beginning of the
6699 block allocated to the structure, so we can free it.
6701 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6703 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
6706 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
6707 (scm_debug_info): New member: id.
6709 * stacks.c: Stacks are now represented as structs; Stacks have an
6710 id given to them by `start-stack'.
6711 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
6713 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
6714 Changed stack representation.
6716 * debug.c (scm_procedure_name): Try procedure property `name' for
6717 compiled closures aswell.
6719 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
6721 * eval.c: scm_i_name moved to gsubr.c
6722 (scm_m_define): Record names of all kinds of procedure
6723 objects. (Earlier, only closures were recorded.)
6725 * procprop.h: Added declaration of scm_i_name.
6727 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
6728 (scm_make_gsubr): Record names of compiled closures.
6730 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6732 * debug.c, debug.h: Removed obsolete code.
6734 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
6735 stacks.c: Renamed regs --> scm_contregs.
6737 * print.c (scm_free_print_state): Cleanup print state before
6738 returning it to pool. It is better to do it here than in
6739 scm_prin1 since scm_prin1 is called often.
6741 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
6742 s_set_source_property_x): Check that first argument is a pair or a
6745 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
6746 scm_i_line, scm_i_column and scm_i_breakpoint global.
6748 * init.c: Added #include "backtrace.h" and #include "stacks.h".
6749 (scm_boot_guile_1): Added calls to scm_init_backtrace and
6752 * debug.h: Added debug object smob declaration and macro
6755 * configure.in: Build with backtrace.o and stacks.o if debug
6758 * Makefile.in: Added entries for new files: backtrace.c,
6759 backtrace.h, stacks.c and stacks.h.
6761 * symbols.c (scm_sym2ovcell): Fixed documentation.
6763 * _scm.h (min, max): Added.
6765 * async.c: Moved `min' macro to _scm.h.
6767 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
6768 SCM_BACKTRACE_INDENT.
6770 * eval.c: Added new debug options `maxdepth' and `indent'.
6772 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
6774 * print.h: Added selector SCM_PRINT_STATE.
6776 * print.c: New functions: scm_make_print_state,
6777 scm_free_print_state.
6779 * print.h: Added declarations for scm_make_print_state,
6780 scm_free_print_state.
6782 * debug.c (scm_m_start_stack): New acro.
6784 * debug.h: Small cleanup.
6786 * init.c (scm_boot_guile_1): Moved scm_init_debug below
6789 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

6809 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,
6810 version.h, vports.c, vports.h, weaks.c, weaks.h: Use SCM_P to
6811 declare functions with prototypes. (Patch thanks to Marius
6814 More prototype-related changes from Marius Vollmer:
6815 * gdb_interface.h: Wrapped header file in #ifdef/#endif
6816 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
6817 * ports.h (ptobfuns): Added prototypes. This means some casting in
6819 * fports.c: Added casts for initializations, since the functions
6820 are defined to take FILE * as their stream argument, not SCM.
6821 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
6822 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
6823 to `char *str_data' to conform to prototype.
6825 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6827 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
6829 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
6831 * stime.c, stime.h: use SCM_P method.
6833 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6835 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
6836 be given at least two arguments. Insist that lst's last element
6837 be a list, but don't make any requirements of its predecessors.
6839 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6841 * eval.c (scm_nconc2last): Revert last change; there seems to be
6842 other stuff going on here.
6844 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
6846 * eval.c (scm_nconc2last): Make sure that each element of lst
6847 (which is a list of argument lists, except for the tail) is a
6848 proper list, i.e., finite and terminated by '().
6850 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6852 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
6855 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
6856 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
6859 * vectors.c (scm_make_vector): Fill vectors with the undefined
6860 value, to help make Guile Scheme code more portable to other
6863 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
6864 * symbols.h, tags.h: Doc fixes.
6866 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
6868 * async.c (scm_take_signal): Doc fixes.
6870 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
6872 * numbers.c (scm_divbigint): When the remainder is zero, we don't
6873 want to subtract it from the modulus; we just want to leave it
6876 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
6878 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
6881 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
6883 * throw.c (scm_catch_apply): Finished implementation of
6886 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6888 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
6890 (scm_init_filesys): set "i/o-extensions" feature.
6893 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
6895 * Makefile.in (root.o): Correct dependencies.
6897 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
6899 * Makefile.in: Added dependency entry for root.o.
6901 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
6902 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
6904 * init.c (scm_start_stack): Set initial root continuation number
6907 * procs.c: New function: scm_thunk_p.
6909 * procs.h: Added declarations of scm_thunk_p.
6911 * root.c: Renamed `call-with-new-root' -->
6912 `call-with-dynamic-root'.
6913 (cwdr): Removed allocation of new root state. This should be done
6914 separately by use of scm_make_root.
6915 (scm_apply_with_dynamic_root): New function: Does what it
6916 sounds like. Needed when spawning threads.
6918 * root.h: Added member last_debug_frame to root state.
6919 Added #include "libguile/debug.h"
6921 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
6922 arguments. The motivation is that code in root.c needs catch
6923 functionality, and we want to avoid code duplication.
6924 New functions: scm_catch, scm_lazy_catch. These are wrappers for
6925 scm_catch_apply. scm_lazy_catch is intended to introduce catch
6926 handlers that run without popping the stack into the dynwind
6929 * throw.h: Added prototypes for scm_catch_apply and
6932 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6934 * root.h (scm_root, scm_set_root): Decouple thread support details
6935 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
6936 SCM_SET_THREAD_LOCAL_DATA.
6938 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
6939 and tortoise scanning loop.
6941 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
6943 * Makefile.in: Rebuild dependencies.
6945 * libguile.h: #include "libguile/print.h" before "smob.h", since
6946 the latter uses the print_state structure.
6948 * throw.c (scm_ithrow): Use the correct variable when checking to
6949 see if a given element of scm_dynwinds is a valid catch.
6951 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
6952 structure, abort; don't just silently ignore the garbage.
6954 * _scm.h: #include "print.h" here, since it seems to be used just
6956 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
6957 strports.c, unif.h: Don't #include "print.h".
6959 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6961 * feature.h (scm_loc_features): Removed external declaration.
6962 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
6964 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6966 * feature.c (scm_init_feature): Added threads feature (needs to be
6967 initialized here, since features doesn't exist when
6968 scm_init_threads is called).
6970 * libguile.h: Added #include "libguile/../threads/threads.h".
6971 (This is a kludge to get thread support working. This should be
6974 * configure.in, acconfig.h: Added flags for thread support.
6976 * scmsigs.c: Define `signal' to be `pthread_signal' if using
6979 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
6980 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
6983 * _scm.h: Added conditional #include "threads.h"
6985 * __scm.h (SCM_ASYNC_TICK): Added call to macro
6986 SCM_THREADS_SWITCHING_CODE.
6988 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
6989 allocate the basic dynamic root object.
6990 (scm_boot_guile): Added call to scm_init_root.
6992 * root.c, root.h: Added root smob.
6993 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
6994 functions: Implements dynamic roots mostly according to spec in
6995 SCM manual. Main difference is that the second argument is a
6996 throw handler rather than an error "thunk".
6998 * root.h: Added declaration of scm_init_root.
7000 * root.c: Added #include "genio.h", #include "smob.h", #include
7001 "pairs.h", #include "throw.h", #include "dynwind.h", #include
7003 (scm_init_root): Added #include "root.x".
7005 * throw.c: Added #include "stackchk.h"
7006 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
7007 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
7008 can be used in scm_call_with_new_root; Added reenabling of stack
7009 checking when catching a throw.
7011 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
7013 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
7015 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
7016 element is not found, as per R4RS.
7018 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7020 * list.c: Doc fixes throughout.
7022 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7024 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7025 declare the char * to be const. Avoids a warning in rgx.c.
7027 * ports.h: spelling fix.
7029 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7032 * load.c (scm_sys_try_load_path): throw an error if file not found
7033 (like it says it in NEWS).
7035 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7037 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7038 PROPS slot to '(), not #f; it's an empty alist.
7040 * throw.h, throw.c: Use SCM_P instead of #if hair.
7042 Remove special support for uncaught throws; see throw.c for
7044 * throw.c (uncaught_throw): New function.
7045 (scm_ithrow): Call uncaught_throw if we don't find a throw
7046 target; don't mess with scm_bad_throw_vcell.
7047 (scm_bad_throw_vcell): Variable deleted.
7048 (scm_init_throw): Don't initialize it.
7050 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7053 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7055 * numbers.c (scm_istr2int): If the number is short (as most
7056 numbers are), just call scm_small_istr2int to deal with it.
7057 (scm_small_istr2int): New function, created by un-#ifdefing the
7058 non-bignum version of scm_istr2int and renaming it.
7060 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7062 * load.c (scm_sys_try_load): don't check whether value returned
7063 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7064 Change the Scheme name from %try-load to primitive-load.
7066 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7067 Can avoid passing a message, allowing it to be derived in the
7068 error handler (e.g., if we want to throw to the key both from
7071 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7073 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7074 references now have a new appearance which is more compact and
7075 also gives a clue about what the target of the reference is.
7076 By setting parameters in the print state, more fancy printing can
7077 be achieved. This is used by the (not yet commited) backtrace
7080 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7082 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7085 * print.c: Added #include "struct.h". Removed function
7088 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7089 scm_iprin1. Removed prototype for scm_prlist.
7091 * arbiters.c (prinarb),
7092 async.c (print_async),
7093 debug.c (prindebugobj, prinmemoized),
7094 eval.c (prinprom, prinmacro),
7095 filesys.c (scm_fd_print, scm_dir_print),
7097 mallocs.c (prinmalloc),
7098 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7099 smob.h (scm_smobfuns),
7100 srcprop.c (prinsrcprops),
7102 unif.c, unif.h (scm_raprin1, rapr1),
7103 variable.c (prin_var): Changed argument `int writing' to
7104 `scm_print_state *pstate'.
7106 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7107 that it will be called before scm_init_print.
7109 * print.c (scm_prin1): Print states are now allocated when calling
7110 scm_prin1 and then passed around to all printing functions as an
7111 argument. A cache `print_state_pool' enables reuse of print
7113 (scm_make_print_state): New function.
7114 (scm_iprin1): Adaption to print states.
7115 (scm_iprlist): An initial "hare and tortoise" scan brings down
7116 time complexity to O (depth * N). (Better time complexity will be
7117 achieved when the printing code is completely rewritten.)
7119 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7121 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7122 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7123 it gets done whether or not the cache variable has a value.
7125 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7127 Distinguish #f and ().
7128 * __scm.h: #undef SICP.
7129 * pairs.h (SCM_EOL): Delete this definition, equating it with
7131 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7132 the value it used to have. Doc fixes, too.
7134 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7136 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7137 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7138 Lord's implementation of structs, allowing for tail arrays as
7139 described in the manual. Also fixed some bugs. (Both the interface
7140 and the implementation should be improved.)
7142 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7144 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7145 People who whish to see the source can do `(print-enable 'source)'.
7146 Removed #ifdef DEBUG_EXTENSIONS.
7148 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7150 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7151 integer (assuming for now accepting an integer is a good thing).
7153 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7154 %S will be used instead for write'ing arguments.
7156 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7157 asserts. fix a few other asserts.
7158 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7159 scm_uniform_vector_ref, scm_array_set_x,
7160 scm_dimensions_to_unform_array): change args in
7161 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7162 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7163 scm_substring_fill_x): likewise.
7164 gsubr.c (scm_gsubr_apply): likewise.
7165 eval.c (SCM_APPLY): likewise.
7167 * eval.c (4 places): replace scm_everr with lgh_error or
7170 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7171 scm_memory_error): new procedures.
7172 scm_everr: deleted. can use scm_wta, dropping first two args.
7173 scm_error: convert NULL subr to SCM_BOOL_F.
7175 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7178 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7181 * error.c, error.h: new error keys: scm_arg_type_key,
7182 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7184 scm_wta: reimplement using lgh_error instead of scm_everr.
7186 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7188 * gdbint.c: scm_lread now has one more argument.
7190 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7191 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7192 loading source from non-file ports, which, e. g., happens when
7193 using the Emacs interface).
7195 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7198 * read.c: Added code for recording of positions of source code
7199 expressions; New functions: recsexpr, scm_lreadrecparen;
7200 _scm_make_srcprops --> scm_make_srcprops
7201 (scm_flush_ws): Removed updating of positions counters. This work
7202 is already done by scm_gen_getc
7204 * read.h: Added prototype for scm_lreadrecparen
7206 * print.c: Added #include "alist.h"
7208 * eval.c: Added #include "hash.h"
7210 * eq.c: Added #include "ramap.h"
7212 * options.c: Documentation fixes.
7214 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7215 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7216 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7217 --> scm_make_srcprops
7219 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7220 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7221 function calls in the definition of the whash access macros.
7223 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7225 * init.c (scm_boot_guile): Add level of indirection to
7226 scm_boot_guile_1() to ensure that stack base pointer is properly
7227 initialized. There was no guarantee that variable i was the
7228 highest/lowest variable on stack (i.e. the call frame of
7229 scm_boot_guile was not completely protected from gc).
7231 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7233 * ports.h (scm_port_table): put back file_name, it will be used to
7234 support debugging. Undo related changes in fports.c, ioext.c,
7237 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7239 * ports.h (scm_port_table): remove file_name member for now, it seems
7241 * fports.c (scm_open_file): don't set file_name in PTAB.
7242 (prinfport): don't use file_name in PTAB.
7243 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7244 * ports.c (scm_add_to_port_table): don't intialize file_name.
7245 (scm_port_file_name): remove for now.
7246 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7248 * fports.h (scm_mkfile): prototype deleted.
7249 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7251 * debug.c, unif.c: use scm_out_of_range instead of
7252 wta for range errors (ASSERT still needs work).
7254 * error.c, error.h (scm_out_of_range): new procedure.
7256 * error.c, error.h (scm_out_of_range_key): new key.
7258 * posix.c (scm_sync): #else was missing.
7260 * error.c, error.h: append _key to names scm_num_overflow and
7263 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7264 of consing an empty list.
7265 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7266 of macros, saves code and string space.
7267 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7268 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7269 lower case. Rename scm_syserror_m to scm_syserror_msg.
7270 error.h: prototypes for new procedures.
7272 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7274 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7276 * error.c, error.h: setup scm_num_overflow key.
7278 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7279 Remove definition of SCM_OVSCM_FLOW.
7281 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7283 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7284 explicit message and args.
7286 * error.c, error.h, __scm.h: change system_error_sym to
7289 * error.c (system_error_sym): remove leading %% from the Scheme name
7292 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7294 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7296 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7297 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7298 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7299 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7300 renamed. (These were introduced by unsupervised name
7303 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7305 * print.c: Added code for detection of circular references during
7306 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7307 a hook for printing of closures (accessible via print options).
7308 This leads to a split of calls to scm_iprin1 into two classes:
7309 elementary print operations (e. g. the code which prints a smob)
7310 still use scm_iprin1 while top level calls (like scm_display) use
7311 scm_prin1. scm_prin1 begins by clearing the data structure used
7312 to record reference information.
7314 * print.h: Added declarations of scm_prin1 and scm_prlist.
7316 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7318 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7320 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7322 * error.c (err_head): scm_iprin1 --> scm_prin1
7324 * debug.c: Adjusted header comment.
7328 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7330 * strerror.c: Doc fix.
7332 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7334 * gdbint.c (gdb_read): Now possible to run during GC.
7335 (unmark_port, remark_port): New functions.
7337 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7339 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7340 of allocating a new string object. Also, increase size by
7341 the factor 2 instead of 1.5.
7343 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7345 * __scm.h (SCM_P): Corrected to run under traditional C.
7347 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7350 * async.c: Calls to scm_sysintern corrected.
7352 * async.h (scm_async_clock): Redundant declaration removed.
7354 * continuations.c (scm_dynthrow): Redundant declaration removed.
7356 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7357 Definition typos corrected.
7359 * debug.h: Missing declarations of functions in debug.c added
7362 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7363 Missing declarations to functions in eval.c added.
7365 * filesys.c: Possibly uninitialized variable rv.
7367 * gc.h (scm_object_addr, scm_unhash_name): Missing
7368 declarations of functions defined in gc.c added.
7370 * genio.c: Possible typos str_data -> wstr_data. ???
7372 * genio.c: Possibly unintended shadowing of local variable
7373 `int c' (gotos out of scope of inner `c'). ???
7375 * init.c: Uninitialized `SCM last' may be used.
7377 * ioext.h: (scm_sys_isatty_p): Typo.
7379 * list.h (scm_list_head): Missing prototype for function in
7382 * numbers.c (scm_two_doubles): Changed from extern to static
7383 (is used only within numbers.c).
7385 * numbers.h: Repeated declarations removed.
7387 * ports.h (scm_close_all_ports_except): Declaration for the
7388 function defined in ports.c added.
7390 * posix.h: Missing declarations added.
7392 * procs.h (scm_make_subr_opt): Missing declaration added.
7394 * socket.h (scm_sys_gethost): Missing declaration added.
7396 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7398 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7399 Missing declarations added.
7401 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7403 * struct.c: Uninitialized variable `SCM answer' may be used.
7405 * unif.c (l2ra): Declaration prototype.
7407 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7408 defined in ramap.c).
7410 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7411 Redundant declarations removed (they are in ramap.h).
7413 * variable.h (scm_make_udvariable,
7414 scm_make_undefined_variable): Declaration corrected to
7415 correspond variable.c.
7417 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7418 Missing declarations added.
7420 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7422 * Makefile.in (distclean): Don't forget to delete fd.h.
7424 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7426 * fd.h.in, tags.h: Trivial cleanups.
7428 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7429 marksweep.h just declared functions from gc.c.
7430 * gc.h, libguile.h: Don't #include "marksweep.h".
7431 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7432 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7433 dependencies updated.
7435 * libguile.h: Don't #include "files.h"; it's been deleted.
7437 * files.c (scm_sys_delete_file): Moved to filesys.c.
7438 File is now empty; deleted.
7440 * filesys.c: scm_sys_delete_file is now here. Remove
7441 #if's; they seem to rely on remnants of an old portability
7442 regimen. If the problems come up again, solve them properly,
7443 using autoconf. Specifically: Don't test M_SYSV, and #define
7444 remove to be unlink if it's #defined; don't use remove just
7445 because HAVE_STDC_HEADERS is #defined.
7446 * filesys.h: Add declarations for scm_sys_delete_file.
7447 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7448 files.o, files.h, files.c, and files.x.
7449 * init.c: Don't #include "files.h", and don't call scm_init_files.
7451 Use SCM_P instead of PROTO; the latter intrudes on the user's
7453 * params.h: Deleted; definition of SCM_P moved to...
7454 * __scm.h: ... here, where it replaces PROTO macro.
7455 * libguile.h, smob.h: Don't #include "params.h".
7456 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7457 smob.h: Fix prototypes accordingly.
7458 * Makefile.in: Update dependencies.
7459 (inner_h_files): Remove params.h.
7461 * gc.c: #include "gc.h"; every module should include its header,
7462 to let the compiler cross-check the declarations against the
7465 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7466 simpos.h: #include "libguile/__scm.h".
7468 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7470 * init.c: Don't forget to #include smob.h and init.h.
7471 * Makefile.in: Dependencies updated.
7473 * smob.h: Use PROTO instead of #if __STDC__.
7475 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7477 * __scm.h: Doc fixes.
7479 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7480 <angles>; this allows `make depends' to work properly.
7482 * libguile.h: #include smob.h and pairs.h before the others; they
7483 define typedefs used by other headers.
7485 C files should #include only the header files they need, not
7486 libguile.h (which #includes all the header files); the pointless
7487 recompilation was wasting my time.
7488 * Makefile.in (all .o dependency lists): Regenerated.
7489 * libguile.h: Don't try to get a definition for size_t here...
7490 * __scm.h: Do it here.
7491 * _scm.h: Since this is the internal libguile header, put things
7492 here that all (or a majority) of the libguile files will want.
7493 Don't #include <libguile.h> here; that generates dependencies on
7494 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7495 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
7496 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

7593 * weaks.c: Get "weaks.h".
7595 * stackchk.h: #include "libguile/debug.h",
7597 * print.h, read.h: #include "options.h", since everyone who uses
7598 either of these files will need that.
7600 * smob.h: #include "ports.h", "genio.h", and "print.h", since
7601 anyone who uses this file will need them to define the smob
7602 printing functions. Also, get markers.h, since people will need
7603 to #define the mark functions.
7605 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
7606 * ports.h: ... to here.
7608 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7609 don't rely on archaic C default type rules.
7611 * fports.h: #include "libguile/ports.h", since you need that in
7612 order to parse this.
7614 * genio.h: #include "libguile/print.h", because you need that to
7615 parse this; don't bother #including "ports.h", since print.h gets
7618 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7620 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7621 this; it's now a reference to an element of *scm_root.
7623 * debug.h: Don't #include "options.h"; the compiler won't be able
7624 to find that once the headers are installed; instead, #include
7625 "libguile/options.h".
7626 * gc.h: Same, with marksweep.h.
7627 * mbstrings.h: Same, with symbols.h.
7628 * scmhob.h: Same, with _scm.h.
7629 * smob.h: Same, with params.h.
7631 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
7632 C files; there's no need for this, and it forces recompilations
7635 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
7637 * error.c (scm_error): declare scm_error_callback.
7639 * error.h: prototype for scm_error_callback.
7641 * __scm.h: define lgh_error.
7642 (SCM_SYSERROR): redefine using lgh_error.
7644 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
7646 * error.c (scm_error): new procedure.
7648 * error.h: prototype for scm_error.
7650 * Makefile.in (install): install scmconfig.h from the current
7651 directory, not $(srcdir).
7653 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7655 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7656 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7657 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
7658 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,

7662 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
7663 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7664 vports.h, weaks.h: #include "libguile/__scm.h", not
7665 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
7666 dependencies are within libguile properly.
7668 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7670 * Makefile.in (.c.x): Simplify; there's no need to run this rule
7671 when scmconfig.h doesn't exist.
7673 * load.c (scm_sys_try_load): Correct spelling.
7675 * feature.c (scm_loc_features): Make this static.
7677 * Makefile.in (libpath.h): Omit trailing slash from path. We
7678 shouldn't require it of users, so why put it here?
7680 Move code to initialize and search %load-path from ice-9 to C
7681 code, so we can use the load-path to find the ice-9 boot code;
7682 this makes it easier to run Guile without installing it. See
7683 corresponding changes in guile/Makefile.in.
7684 * feature.c: Move stuff concerned with the load path to load.c.
7685 (scm_compiled_library_path): Deleted.
7686 Don't #include libpath.h here.
7687 * feature.h: Don't mention scm_compiled_library_path.
7688 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
7689 <sys/stat.h>, and <unistd.h> (if present).
7690 (R_OK): #define if the system hasn't deigned to.
7691 (scm_loc_load_path): New variable.
7692 (scm_init_load_path, scm_sys_search_load_path,
7693 scm_sys_try_load_path): New functions.
7694 (scm_init_load): Initialize scm_loc_load_path to point to the
7695 value cell of the Scheme %load-path variable.
7696 * load.h: Add declarations for scm_sys_search_load_path,
7697 scm_sys_try_load_path.
7698 * init.c: Call scm_init_load_path.
7699 * Makefile.in (feature.o, load.o): Dependencies updated.
7701 * load.c, load.h: Rewrite using PROTO macro.
7703 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7705 * gc.c (scm_cellp): New function: C predicate to determine if an
7706 SCM value can be regarded as a pointer to a cell on the heap.
7708 * gc.h: Added declaration of scm_cellp.
7710 * gdb_interface.h: New file: The GDB interface header from the GDB
7713 * gdbint.c: New file: GDB interface.
7715 * gdbint.h: New file: GDB interface.
7717 * libguile.h: Added #include <libguile/gdbint.h>.
7719 * init.c (scm_boot_guile): Added scm_init_gdbint.
7721 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
7722 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
7723 found if object files and source are kept separate).
7725 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
7727 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
7729 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
7731 * configure.in: Don't substitute the values of TCL_SRC_DIR and
7732 TK_SRC_DIR; they're not relevant any more.
7734 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
7735 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
7737 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
7739 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
7740 search path, so we can find the <libguile/MUMBLE.h> headers.
7742 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
7744 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
7745 implicit in the .c.o rule.
7746 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
7749 Put the library path in a header file, instead of passing it on
7750 the command line in every compilation.
7751 * Makefile.in (libpath.h): New target.
7752 (feature.o): Depend on libpath.h.
7753 (clean): Delete libpath.h.
7754 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
7755 * feature.c: ... #include "libpath.h" here.
7756 * .cvsignore: Ignore libpath.h.
7758 Don't install the unwashed masses of Guile header files in the
7759 main #include path; put most of them in a subdirectory called
7760 'libguile'. This avoids naming conflicts between Guile header
7761 files and system header files (of which there were a few).
7762 * Makefile.in (pkgincludedir): Deleted.
7763 (innerincludedir): New variable; this and $(includedir) are enough.
7764 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
7765 (installed_h_files): Divide this up. Now this variable lists
7766 those header files which should go into $(includedir) (i.e. appear
7767 directly in the #include path), and ...
7768 (inner_h_files): ... this new variable says which files appear in
7769 a subdirectory, and are referred to as <libguile/mumble.h>.
7770 (h_files): List them both.
7771 (install): Create innerincludedir, not pkgincludedir. Put
7772 the installed_h_files and inner_h_files in their proper places.
7773 (uninstall): Corresponding changes.
7774 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7775 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7776 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
7777 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
7778 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,
7779 print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
7780 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
7781 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
7782 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7783 vports.h, weaks.h: Find __scm.h in its new location.
7784 * __scm.h: Find scmconfig.h and tags.h in their new locations
7785 (they're both "inner" files).
7787 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
7789 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
7791 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7793 * posix.c: Doc fixes.
7795 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
7797 * socket.c: Don't include a prototype for inet_aton; just use a
7798 K&R style declaration, to avoid warnings but minimize the chance
7799 of conflicts with the system.
7801 On NextStep, <utime.h> doesn't define struct utime, unless we
7802 #define _POSIX_SOURCE before #including it.
7803 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
7804 * acconfig.h: New comment text for above CPP symbol.
7805 * configure.in: Call it.
7806 * posix.c: #define _POSIX_SOURCE if it seems necessary.
7808 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
7810 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
7811 testing for __EMX__.
7813 * posix.c: #include <libc.h>, if it exists.
7815 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
7816 don't even know if the latter exists.
7818 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
7819 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
7820 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
7822 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
7824 (scm_init_posix): Use them when initializing the Scheme constants
7827 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7829 * Makefile.in (libdir, includedir, bindir): Use the
7830 autoconf-supplied values, instead of deriving them ourselves.
7831 (pkgincludedir, datadir, pkgdatadir): New variables.
7832 (install, uninstall): Put the header files in a special
7833 subdirectory, not in the main search path.
7835 * Makefile.in (ALL_CFLAGS): Provide the proper value for
7836 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
7838 * Makefile.in (IMPLPATH): Deleted; never used.
7840 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
7841 on the Tcl/Tk source any more.
7842 (INCLUDE_CFLAGS): Remove references to the above.
7844 * Makefile.in (version.o): Corrected dependencies.
7846 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
7848 * libguile.h: #include "version.h"
7850 * init.c (scm_boot_guile): Call scm_init_version.
7851 * gscm.c (gscm_run_scm): Call scm_init_version.
7853 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
7854 GUILE_VERSION): AC_DEFINE these.
7855 (acconfig.h): #undef the above symbols.
7857 * Makefile.in (libobjs): Add version.o.
7858 (installed_h_files): Add version.h.
7859 (c_files): Add version.c.
7860 (gen_c_files): Add version.x.
7861 (version.o): New rule.
7862 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
7863 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,
7864 fdsocket.o, feature.o, files.o, filesys.o, fports.o, gc.o,
7865 genio.o, gsubr.o, hash.o, hashtab.o, init.o, kw.o, list.o, load.o,
7866 mallocs.o, markers.o, marksweep.o, mbstrings.o, numbers.o,
7867 objprop.o, pairs.o, ports.o, posix.o, print.o, procprop.o,
7868 procs.o, ramap.o, read.o, root.o, scmsigs.o, sequences.o,
7869 simpos.o, smob.o, socket.o, stackchk.o, stime.o, strings.o,
7870 strop.o, strorder.o, strports.o, struct.o, symbols.o, tag.o,
7871 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
7872 weaks.o): Add version.h to dependency lists.
7873 (markers.o): Remove duplicate rule.
7875 * version.h: New file.
7877 * version.c: New file.
7879 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7881 * symbols.c (scm_strhash): scm_downcase is now a function, not an
7882 array; use it appropriately. Since GCC is quite happy to
7883 subscript functions, it never warned us about this; we should use
7884 -Wpointer-arith in the future. I guess we never tested
7887 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
7889 * socket.c: Doc and copyright fixes.
7891 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7893 * debug.c: Fixed and improved gdb support.
7895 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7897 * socket.c: Added declaration of inet_aton to avoid compiler
7898 warning. (Hope this solution is correct.)
7900 * stime.c: Added declaration of ftime. (This is missing in
7903 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
7905 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
7907 * Makefile.in (c_files): add strerror.c.
7909 * strerror.c: new file from Emacs' sysdep.c.
7910 maybe configure should also check for sys_errlist.
7912 * configure.in (AC_REPLACE_FUNCS): add strerror.
7914 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7916 * debug.c (scm_init_debug): Added initialization for
7917 scm_evaluator_traps.
7919 * debug.h, debug.c: Various name changes.
7920 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
7921 "debug-options-interface". See commentary in options.c.
7923 * options.h, options.c: Options now have documentation strings.
7924 Also added a long explanatory commentary.
7926 * eval.c, print.h, print.c, read.h, read.c: Modifications to
7929 * gscm.c, init.c, root.c, throw.c: Bug fixes:
7930 last_debug_info_frame is now updated in all cases.
7932 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
7935 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7937 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
7938 Added option STACK_CHECKING.
7940 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7942 * Makefile.in: Added {debug,options,srcprop}.{h,c}
7944 * __scm.h: Removed symbols for debugging support.
7946 * acconfig.h: Added symbols for debugging support.
7948 * configure.in: Added user option for debugging support.
7949 --enable-debug will include the debugging code into libguile.a.
7951 * continuations.c (scm_make_cont): Enlarged the #if 0 around
7952 scm_relocate_chunk_to_heap.
7954 * debug.c: New file: low-level debugging support. It also
7955 includes support for debugging with gdb. (The extensions to gdb
7956 are written by Per Bothner at Cygnus.)
7958 * debug.h: New file: low-level debugging support.
7960 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
7961 argument pairs. Extensive modifications to the debugging
7962 evaluator. Added "SECTION:" commentaries to clarify what happens
7963 when, during double compilation. Renamed EVALIMP --> EVALIM.
7964 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
7965 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
7966 the beginning of the file. New procedure: scm_unmemocopy.
7967 Added some global state variables needed by the debugging
7968 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
7969 check_entry, check_apply, check_exit, debug_options and
7970 evaluator_traps. New acro: undefine.
7972 * eval.h: Renamed EVAL --> XEVAL.
7974 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
7975 --> scm_make_weak_key_hash_table.
7977 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
7978 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
7980 * libguile.h: Conditionally include debug.h
7982 * objprop.c (scm_object_properties, scm_set_object_properties_x):
7983 scm_object_properties shouldn't return handle. `handle' now gets
7984 initialized in scm_set_object_properties_x. scm_object_properties
7985 doesn't any longer create an entry in scm_object_whash.
7987 * options.c: New file: handling of run time options.
7989 * options.h: New file: handling of run time options.
7991 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
7993 * print.c: New procedure: scm_print_options
7995 * print.h: Defines for print options.
7997 * read.c: New procedure: scm_read_options
7999 * read.h: Defines for reader options.
8001 * root.h: Added scm_source_whash among scm_sys_protects.
8003 * srcprop.c: New file: source properties.
8005 * srcprop.h: New file: source properties.
8007 * throw.c (jbsmob): Jump buffers are now correctly allocated.
8008 (Bug found by A. Green.)
8010 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8012 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
8014 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
8016 * libguile.h: #include "objprop.h"; I guess this was forgotten.
8018 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
8019 and should be called by the final client.
8021 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8023 * gc.h: Use the PROTO macro when declaring functions.
8024 * gc.c: Use the PROTO macro when declaring static functions.
8025 Remove the CPP hair around function definitions.
8027 * gc.c (scm_init_storage): Initialize scm_asyncs.
8029 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8030 preprocessor symbol; "__scm.h" is where it might get #defined.
8031 * __scm.h: Similar: #include <scmconfig.h> before testing
8034 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8036 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8038 * init.c (scm_boot_guile): Add init_func argument; call
8039 (*init_func) instead of calling scm_appinit; it's ucky to
8040 hard-code names for the user's procedures.
8041 * init.h (scm_boot_guile): Adjust declaration.
8043 * __scm.h (PROTO): New macro, for declaring functions with
8046 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8047 eliminate all the __STDC__ conditionals.
8048 (scm_boot_guile): Add declaration.
8049 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8050 Remove __STDC__ conditionals around function definitions; the
8051 declarations in init.h will provide the same information, more
8054 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8055 complain about it in the error message; the error message is
8056 adequate without that note, and there's nothing the user can do
8059 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8061 * Makefile.in (ancillary): Drop def.sed.
8063 * posix.c (scm_init_posix): Use numeric values, rather than
8064 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8065 F_OK. The symbols aren't available on some systems, and I'm
8066 pretty sure their values are fixed by common widespread practice.
8067 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8069 More functions unavailable on some systems.
8070 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8071 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8073 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8074 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8075 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8076 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8077 stub that signals an error as the #else.
8079 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8081 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8083 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8085 * unif.c: include ramap.h.
8087 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8089 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8091 * ports.c: include sys/ioctl.h.
8093 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8095 * configure.in: check for sys/ioctl.h.
8097 * ports.c: include <malloc.h> not "malloc.h".
8099 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8101 * fports.c: remove ttyname and tmpnam declarations.
8103 * posix.c: fewer ttyname declarations.
8105 * fports.c: include <string.h> not "string.h".
8107 * init.c, ioext.c: include string.h and unistd.h.
8109 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8111 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8112 genio.c, simpos.c, vports.c: include string.h.
8114 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8116 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8118 (scm_addr_buffer_size): change type from scm_sizet to int.
8119 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8120 from scm_sizet to int.
8122 * error.c: include unistd.h.
8124 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8127 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8129 * __scm.hd, def.sed: deleted.
8131 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8133 Changes for NeXT, suggested by Robert Brown.
8134 * configure.in: Call AC_TYPE_MODE_T.
8135 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8136 NeXT. Put header file list in alphabetical order.
8137 * configure, scmconfig.h.in: Regenerated.
8138 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8140 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8143 * acconfig.h: New file, providing documentation for the CPP
8144 symbols defined in configure.in
8145 * acconfig-1.5.h: Removed; superceded by the above.
8147 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8149 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8151 * fports.c (scm_open_file): don't return #f, throw error.
8153 * ioext.c (fileno): renamed from %fileno.
8154 (soft-fileno): deleted.
8156 * ports.c (scm_port_revealed): don't need to check for -1 from
8158 (scm_set_port_revealed_x): return unspecified, not #f.
8160 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8162 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8164 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8166 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8168 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8170 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8171 This is necessary on Ultrix, and doesn't hurt portability.
8173 * Makefile.in (dist-dir): New target, implementing a new dist system.
8174 (installed_h_files): Put in alphabetical order.
8175 Remove duplicate entries for markers.h and unif.h.
8176 (c_files): Remove duplicate entries for markers.c.
8177 (ancillary): Renamed from anillery; all uses changed. Remove
8178 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8179 Remove all the ../doc/* files; doc/Makefile.in handles that.
8181 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8183 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8184 every if must have an else, or else the whole command has a
8185 non-zero exit code whenever the if's condition is false.
8187 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8189 * posix.c: include string.h.
8191 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8193 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8196 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8197 Remove leading % from scheme names.
8198 Do not return error values, call SCM_SYSERROR or similar.
8200 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8202 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8204 * struct.c (scm_init_struct): new file.
8206 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8208 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8209 (scm_list_head): added list-head for rapidly chopping argument
8210 lists off of longer lists (and similar).
8212 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
8214 * objprop.c (scm_object_property): assq the cdr of the whash
8215 handle for obj, not the handle itself.
8217 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8219 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8220 weak hash tables last of all marking to avoid an obscure gc bug.
8221 WARNING: circular lists stored in a weak hash table will hose us.
8223 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8225 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8226 new functions similar to scm_substring_move_left_x and
8227 scm_substring_move_right_x.
8229 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8231 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
8234 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
8236 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8238 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8240 * strports.c (scm_strprint_obj): convenience function. C for
8241 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8243 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8244 removed to a separate library
8246 * init.c (scm_boot_guile): copied from guile-tcl.c.
8247 Initialization specific to tcl interpreters removed.
8249 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8251 * ports.c (scm_ports_prehistory): size malloced here doesn't
8252 matter so long as it is non-0 (got rid of "* 4").
8254 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8256 * gscm.h: gscm_mkarray eliminated (presumably was not being used

8261 * mallocs.[ch]: back again (for rx at least).
8263 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8265 * ports.c: removed functions relating to the mapping between ports
8266 and descriptors. (That stuff is unix-specific and should be collected

8274 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8275 handled correctly (SCM_FREEP was applied to them) -- test for
8276 NIMP. Keys in weak hash tables were spuriously (though harmlessly)

8321 (possibly triggering gc) before setting the tag of the corresponding
8324 * pairs.c (scm_delq_x): never throw an error.
8326 * vectors.c (scm_make_vector): made the default vector fill argument
8327 into '() (much more useful than the previous value, "#unspecified")

8331 * ports.c (scm_add_to_port_table): Added fields
8332 to port table entries: file_name, line_num, col.

8444 initialization to fix a race condition.
8446 * continuations.c (scm_dynthrow): pass throwval in the 'regs'

8470 set the multi_byte flag correctly in symbols. This is wrong.
8471 intern_obbary_soft and msymbolize should take an extra parameter.
8472 Also, weird multibyte symbols don't print correctly.
8473 The weird symbol syntax is also a bit bogus (emacs doesn't quite
