1 1999-08-19 Gary Houston <ghouston@easynet.co.uk>
3 * fports.c (fport_write): fix line-buffering mode again.
4 (scm_open_file): recognise 'l' for line-buffering.
5 (scm_setvbuf): recognise _IOLBF for line-buffering.
7 1999-08-19 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
9 * Makefile.am (libguile_la_LDFLAGS): Increased the version number
12 * eval.c (SCM_APPLY), sort.c (closureless): Expand body when
15 1999-08-18 Gary Houston <ghouston@easynet.co.uk>
17 * fports.c (fport_write): use memcpy instead of strncpy, in case
18 the data contains NUL.
20 1999-08-17 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
22 * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.)
24 * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h,
25 read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line,
26 scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source,
27 scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else,
28 scm_i_unquote, scm_i_uq_splicing, scm_i_apply, scm_i_enter_frame,
29 scm_i_apply_frame, scm_i_exit_frame, scm_i_trace, scm_i_quote,
30 scm_i_begin, scm_i_if, scm_i_and, scm_i_or, scm_i_case,
31 scm_i_cond, scm_i_letstar, scm_i_do, scm_i_quasiquote,
32 scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply,
33 scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use
34 scm_sym_ as prefix for symbols.
36 * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed.
38 * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and,
39 scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do,
40 scm_sym_define, scm_sym_letrec, scm_sym_atapply,
41 scm_sym_atcall_cc): Made global.
43 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
45 * eval.c (scm_sym_args): Made global.
47 * objects.c (scm_set_object_procedure_x): Disallow setting of
48 procedures for pure generic functions.
50 1999-08-12 Gary Houston <ghouston@easynet.co.uk>
52 * ports.c (scm_seek): one more: was scm_lseek. Also changed the
53 Scheme name from lseek to seek, but lseek was added recently so
54 it shouldn't be a big problem.
55 * ports.c, gdbint.c, ioext.c: changed callers.
57 1999-08-11 Gary Houston <ghouston@easynet.co.uk>
59 * fports.c (fport_input_waiting): if select is used, return 1
60 instead of whatever FD_ISSET expands to. maybe it will be useful
61 to interpret the value from the input_waiting ptob procedure as a
62 lower bound on the number of bytes available.
64 * Mikael asked for a few names to be changed...
66 * ports.c (scm_make_port_type): take the write procedure as the
67 second argument instead of the flush procedure.
68 * ports.h (scm_ptob_descriptor): rename the ptob procedures:
69 fflush -> flush, read_flush -> end_input, fclose -> close,
70 fill_buffer -> fill_input, ftruncate -> truncate,
71 input_waiting_p -> input_waiting.
73 * ports.c (end_input_void_port): was read_flush_void_port.
74 (scm_set_port_end_input): was scm_set_port_flush_input.
75 (scm_set_port_flush): was scm_set_port_write.
76 (scm_set_port_input_waiting): was scm_set_port_input_waiting_p
77 (scm_end_input): was scm_read_flush.
78 (scm_fill_input): was scm_fill_buffer.
79 (scm_flush): was scm_fflush.
80 * fports.c (fport_input_waiting): renamed from fport_input_waiting_p.
81 (fport_end_input): was local_read_flush.
82 (fport_flush): was local_fflush.
83 (fport_close): was local_fclose.
84 (fport_truncate): was local_ftruncate.
85 (fport_seek): was local_seek.
86 (fport_free): was local_free.
87 (fport_fill_input): was fport_fill_buffer.
88 * strports.c (st_end_input): was st_read_flush.
89 (st_truncate): was st_ftruncate.
90 * vports.c: (sf_flush): was sfflush.
91 (sf_close): was sfclose.
92 (sf_fill_input): was sf_fill_buffer.
94 * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c:
97 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
99 * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch
100 forms now contain the expressions to be dispatched upon instead of
101 depending on a surrounding lambda or let; Generic function
102 dispatch has been optimized; `apply' on a generic function now
103 works a little bit strangely. It uses a trick so that the type
104 dispatch code in SCM_CEVAL can be reused.
106 * objects.h, objects.c (scm_apply_generic_env): Added (used by
108 (scm_operator_p): Added.
109 (scm_sym_atdispatch): Added.
110 (scm_set_object_procedure_x): Modified to handle the new style
112 (scm_object_procedures): New debugging procedure.
114 1999-08-05 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
116 * eval.c, eval.h (scm_sym_args): Added.
118 * objects.h (SCM_CLASSF_PURE_GENERIC): Added.
120 * feature.c, feature.h (scm_c_run_hook): Added.
122 * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to
123 cdrxnoap and loopnoap instead of begin and loop.
125 1999-08-04 Gary Houston <ghouston@easynet.co.uk>
127 * ports.c (scm_putc, scm_puts),
128 * unif.c (scm_uniform_array_write): use scm_lfwrite.
129 * ports.c (scm_putc): change type of first argument from int to char.
131 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
133 * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and
134 SCM_IM_HASH_DISPATCH.
136 * objects.h (SCM_CLASSF_GOOPS_VALID): Added.
137 (scm_si_redfined, scm_si_hashsets): Moved.
139 * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID
140 flag which combines type and status info so that the class
141 redefinition protocol has zero cost during normal execution.
143 1999-08-03 Gary Houston <ghouston@easynet.co.uk>
145 * ports.h (scm_ptob_descriptor): include a write procedure again.
146 it's more efficient for unbuffered fports (e.g., sockets.)
148 * ports.c (scm_puts): use ptob->write.
149 * vports.c (scm_make_sfptob): set write proc in ptob.
150 * strports.c (scm_make_stptob): set write proc in ptob.
151 * ports.c (write_void_port): new procedure.
152 * vports.c (sf_write): new procedure.
153 * ports.c (scm_lfwrite): use ptob->write.
154 * strports.c (st_write): new procedure.
155 * fports.c (fport_write): new procedure.
156 (scm_make_fptob): set write in ptob to fport_write.
157 * ports.h: prototype for scm_set_port_write.
158 * ports.c (scm_make_port_type): initialise ptob write procedure.
159 (scm_set_port_write): new proc.
161 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com>
163 * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry
164 until we've verified that it is actually a port. (Thanks to
167 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
169 * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary
170 code, particularly an unnecessary test (len != size, where len ==
171 size). (Was this leftovers from debugging code, or have I missed
174 * hashtab.c: Bugfix: Don't declare s_hash_fold without storage
175 size. (Thanks to James Dean Palmer.)
177 * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part.
178 (Thanks to Lorentey Karoly.)
180 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
182 * eval.c (scm_m_expand_body): Use scm_cons_source.
184 * struct.c (scm_print_struct): Use vtable name.
186 * print.c (scm_init_print): Set name of print state type.
188 * stacks.c (scm_init_stacks): Set name of stack type.
190 1999-07-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
192 * eval.c (SCM_CEVAL): Removed old implementation of internal
195 * gsubr.c, procprop.h (scm_i_inner_name): Removed.
197 * debug.c, debug.h (scm_reverse_lookup): Added.
198 (scm_procedure_name): Use scm_reverse_lookup to lookup the name of
199 internal procedure definitions; Don't use scm_i_inner_name.
201 * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X):
204 * eval.h: Added prototypes for multi language support functions.
206 * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use
207 improper lists in the low-level representation, since that will
208 cause a begin to be prepended at macro expansion.
210 * eval.c (scm_cons_source): Version of cons which copies source
211 properties from an existing cell.
212 (scm_copy_tree, SCM_CEVAL): Use scm_cons_source.
214 * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto
215 procedure source before calling scm_unmemocopy instead of faking
218 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de>
220 Ported `internal defines' fix from SCM. Original ChangeLog entry:
222 1998-07-09 Radey Shouman <radey@colorage.com>
224 * eval.c (ceval_1): Modifications to allow rewriting of interal
225 DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
226 body of which it is the CAR is macro expanded by m_expand_body,
227 which rewrites internal DEFINE.
229 (m_expand_body): Added.
231 (m_macroexp1): Added argument to control error checking:
232 m_expand_body may speculatively expand forms in the wrong
233 environments. Made argument number checks conditional on
236 (m_body): Added, error checks bodies and inserts the ISYM tokens.
238 (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now
241 (m_cond): (m_case): (m_quote): Modified to avoid destructively
242 changing their argument forms. Since m_expand_body
243 speculatively macro expands forms the process must be
246 (m_ident_eqp): Fixed to use proper environment.
248 (renamed_ident): Added DEFER_INTS_EGC.
250 Added prototypes for static functions.
256 (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK
257 is false, do not produce an error for unbound variables, return a
258 pointer to cell_undef instead.
260 (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1.
264 (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid
265 destructively changing their argument forms. Since m_expand_body
266 speculatively macro expands forms the process must be reversible.
268 (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for
269 SCM_IM_LET introduced by named lets.
271 (scm_m_letstar): Use scm_m_body instead of bodycheck.
273 (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and
274 scm_letrec. scm_letrec1 does not check for a null binding and
275 takes an additional argument to specify the ISYM of the body. Use
276 scm_m_body instead of bodycheck.
278 (scm_m_let): Use scm_m_body instead of bodycheck.
280 (scm_m_expand_body, scm_macroexp): New.
282 (unmemocopy): Account for ISYMs introduced by scm_m_body.
284 (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with
285 check=1. Throw error for internal defined that have not been
286 rewritten by scm_m_expand_body.
288 * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp.
289 Removed prototype for SCM_APPLY.
291 * tags.h: Added extern declaration of scm_isymnames.
293 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
295 * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c.
297 * lang.c: New file: Beginning of multi-language support.
299 * init.c (scm_boot_guile_1): Added call to scm_init_lang ().
301 * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case.
302 (scm_dynamic_wind): Added argument checking for the after guard so
303 that we don't add garbage on the dynwind chain.
304 (scm_swap_bindings): Added.
306 * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY,
307 SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c
308 (scm_isymnames): New isyms for multi-language support.
310 * eval.c (scm_nil, scm_t): New symbols.
311 (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special
312 forms for multi-language support.
314 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
316 * random.c, random.h (scm_c_default_rstate, scm_c_uniform32):
318 Renamed functions in the random function library interface
319 from scm_i_XXX --> scm_c_XXX.
321 1999-07-25 Gary Houston <ghouston@easynet.co.uk>
323 * ports.c (scm_putc): fix line-buffering.
325 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
327 * ports.c, ports.h, fports.c, strports.c, vports.c: Renamed
328 scm_set_ptob_XXX --> scm_set_port_XXX.
330 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
332 * ports.c, ports.h (scm_make_port_type): New interface for
333 creation of port types (replaces scm_newptob). Just as for the
334 smobs, we need to separate the internal representation of smob
335 types from the interface, so that we easily can add new fields and
336 rearrange things without caring about backward compatibility.
337 This change was forced by the need in GOOPS to create classes
338 representing port types.
339 (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print,
340 scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close,
341 scm_set_ptob_seek, scm_set_ptob_truncate,
342 scm_set_ptob_input_waiting_p): New setters.
343 (scm_newptob): Rewritten to use scm_make_port_type. For backward
345 (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor.
346 (scm_prinport): Removed.
347 (scm_port_print): Added.
348 (scm_print_port_mode): Added.
349 (void_port_ptob, print_void_port, close_void_port, noop0):
350 Removed. Removed #include "genio.h" Added #include "objects.h",
353 * fports.c (prinfport): Moved code from ports.c.
355 (scm_fptob): Removed. Instead use new interface.
356 (scm_make_fptob): Added. (Need to create basic ports in a
357 specific order in ports.c.)
359 * strports.c (scm_stptob, prinstpt, noop0): Removed
360 (scm_make_stptob): Added.
362 * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed.
363 (scm_make_sfport): Added.
365 * filesys.c (scm_dir_print): Don't use the port printing code.
366 Instead provide specific directory printer.
368 * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free.
370 * ioext.c (scm_redirect_port): Replaced scm_ptobfuns -->
373 * smob.c (scm_smob_print): Handle non-existing type name nicely.
374 Removed #include "genio.h"
376 * objects.c (scm_make_port_classes): New function ptr.
378 1999-07-24 Gary Houston <ghouston@easynet.co.uk>
380 * gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
382 * ports.c (scm_truncate_file): renamed from scm_ftruncate.
383 allow the 1st argument to be a fdes or filename as well as a
384 port (as in the filesys.c version).
386 * filesys.c (scm_truncate_file): removed.
388 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se>
390 * readline.c, readline.h: Removed.
392 * objects.c, objects.h (scm_port_class): Added.
393 (scm_class_of): Look up port class in scm_port_class.
394 (SCM_IN_PCLASS_INDEX, SCM_OUT_PCLASS_INDEX,
395 SCM_INOUT_PCLASS_INDEX): Added.
398 * Makefile.am: Removed genio.c, genio.x.
402 1999-07-23 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>
404 * init.c: Make sure that scm_post_boot_init_modules is called only
405 once. (Important when using a dumped image.; Thanks to Bernard
408 1999-07-19 Jim Blandy <jimb@savonarola.red-bean.com>
410 * guardians.c (scm_guardian_zombify): Separate scanning for
411 zombies from marking the pairs of the free list.
413 * guardians.c (scm_guardian_zombify): Don't set marks manually ---
414 use the macros. (Thanks to Michael Livshin.)
416 * eval.c (scm_m_lambda): Let bodycheck check the body of the
417 lambda. Let your sins be purified by the blood of the lambda.
418 (Thanks to Eric Hanchrow.)
420 * net_db.c (h_errno): Don't declare this if it's #defined. Eew.
421 (Thanks to Valdis Kletnieks.)
423 Fixes for EMX from Mikael Ståldal.
425 * filesys.c: #include <io.h>, if we have it.
426 * scmconfig.h.in: Regenerated.
428 * stime.c (ftime): Delete declaration for this function --- let
429 the system supply it.
431 Cleanups from John Bley.
433 * gdbint.c: Don't include <stdio.h> and "_scm.h" twice.
435 * gsubr.c: Don't include "gsubr.h" twice.
437 Cleanups for compilation on Irix 6, from David Kaelbling.
439 * regex-posix.c (scm_regexp_error_msg): Change `rx' argument to
440 regex_t pointer. This is what the callers have, mostly.
441 (scm_regexp_exec): Don't forget to pass the `rx' argument to
442 scm_regexp_error_msg.
444 * scmsigs.c (scm_sigaction): Cast SIG_DFL and SIG_IGN to SCM, not
445 int. That way, if we get a warning on this line, it's more likely
446 that we're really missing bits we care about.
448 * snarf.h (SCM_CONST_LONG): Remove trailing semicolon from
451 * tags.h (SCM_IMP, SCM_NCONSP, SCM_NCELLP, SCM_ITAG3, SCM_TYP3,
452 SCM_TYP7, SCM_TYP7S, SCM_TYP16, SCM_TYP16S, SCM_GCTYP16,
453 SCM_GCMARKP, SCM_GC8MARKP): Don't cast to int. Either SCM or no
454 cast at all is more appropriate in every case. At the moment, we
455 assume everywhere that SCM is an integral type anyway.
457 1999-07-14 Gary Houston <ghouston@easynet.co.uk>
459 * unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
460 read_pos after scm_fill_buffer.
462 * ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
465 * vports.c (sf_fill_buffer), strports.c (stfill_buffer),
466 fports.c (fport_fill_buffer): implement the interface change.
468 * ports.c (scm_fill_buffer): interface change: no longer increments
469 read_pos past the character that's returned. it seems clearer to
470 leave it to the caller to decide what to do (thanks Jim).
472 * vports.c (sf_fill_buffer): put the read char into the buffer
473 as well as returning it.
475 * ports.c (scm_grow_port_cbuf): residue of this deleted procedure
478 1999-07-13 Gary Houston <ghouston@easynet.co.uk>
480 * strports.c (scm_strprint_obj): simplify. start with initial
482 (st_seek): don't allow string to be extended if seeking past
483 the end of a read-only port.
485 1999-07-12 Gary Houston <ghouston@easynet.co.uk>
487 * strports.c (st_seek): change the resize checks.
489 * ports.c (scm_ftruncate): throw error if offset works out negative.
491 * strports.c (st_flush): increase string size in blocks of
492 SCM_WRITE_BLOCK instead of 1. set read_end to read_pos if
493 it's greater and reset read_buf_size.
494 (scm_mkstrport): set rw_randow if only writing, since read_buf needs
495 to be maintained for output ports too (it holds the written
496 part of the string, while write_buf may have unwritten buffer
498 (st_truncate): rewritten.
499 (top of file): added a few notes.
501 1999-07-10 Jim Blandy <jimb@savonarola.red-bean.com>
503 Patch from Greg Badros:
504 * snarf.h (SCM_PROC, SCM_PROC1): Use __cplusplus or
505 GUILE_CPLUSPLUS_SNARF macros to force adding a cast to the last
506 (function pointer) argument to scm_make_gsubr and scm_make_subr
507 calls. This avoids warnings in C++ programs using guile-snarf.
509 1999-07-06 Gary Houston <ghouston@easynet.co.uk>
511 * strports.c (st_grow_port): set pt->read_pos. set
512 pt->read_buf_size one less than pt->write_buf_size if there's
513 an unwritten char at the end of the string. similarly for
515 (st_resize_port): renamed from st_grow_port.
516 (st_seek): simplify by assuming that pt->write_pos == pt->read_pos.
517 seek from read_end instead of write_end for SEEK_END.
518 (st_ftruncate): calculate current length using readbuf, not write
520 (scm_strport_to_string): use read_buf_size for length.
521 (stfill_buffer): don't re-initialise the readbuf.
523 1999-07-05 Gary Houston <ghouston@easynet.co.uk>
525 * strports.c (scm_strport_to_string): new procedure.
526 (scm_call_with_output_string, scm_strprint_obj): use
527 scm_strport_to_string.
528 used SCM_INUM0 instead of SCM_MAKINUM (0) in a few places.
530 1999-07-08 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se>

716 surrounded by parens. It's more readable.
718 * eval.c (scm_map, scm_for_each): Verify that all arguments are
719 proper lists, and of the appropriate lengths.

765 instead of stepping through an array.
766 (scm_gc_sweep): Update offset used to find start of weak vector to
768 (scm_init_storage): Set scm_weak_vectors to EOL.
770 Fix from Ken Raeburn <raeburn@raeburn.org>:
771 * gc.c (already_in_gc): New variable.

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

792 ChangeLog entries and the patch from two different places...
794 1999-06-09 Jim Blandy <jimb@savonarola.red-bean.com>
796 * gc.c (scm_igc): Check for scm_mallocated underflow. Otherwise,
797 it shows up as terrible performance, as we GC constantly.
799 * ioext.c (scm_do_read_line): Rewritten to use memchr to find the
800 newline. A bit faster, and definitely hairier.
801 (scm_read_line): Count newlines here instead.
803 * strings.c (scm_take_str): New function.
804 (scm_take0str): Reimplement in terms of scm_take_str. * strings.h

819 1999-04-26 Gary Houston <ghouston@easynet.co.uk>
821 * ports.c: (scm_lseek): clear buffers even if just reading current
824 * fports.c (local_fclose): call local_fflush unconditionally.

842 fports.h (scm_port): change size types from int to off_t.
843 ports.c (scm_init_ports): initialise the seek symbols here
844 instead of in ioext.c.
845 strports.c (scm_call_with_output_string): start with an empty
846 string, so seek and ftruncate can be used.
848 gdbint.c: adjust string port usage.
850 1999-04-24 Gary Houston <ghouston@easynet.co.uk>
852 * ports.h (scm_ptobfuns): add a read_flush procedure which is the
853 equivalent to fflush for the read buffer.
854 * ports.c (scm_newptob): set read_flush.
855 ports.c (void_port_ptob): set read_flush.
856 fports.c (local_read_flush): new proc. add to ptob.
857 strport.c (st_read_flush): likewise.

860 left but fdes. leaving it as a struct to allow for future changes.
861 fports.c: replace usage of scm_fport::random with scm_port::rw_random.
862 ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
863 ptob proc if the read buffer is filled.
865 1999-04-23 Gary Houston <ghouston@easynet.co.uk>
867 * ports.h (scm_port): add a rw_random member and replace
868 reading and writing members with rw_active member.
869 SCM_PORT_READ/SCM_PORT_WRITE: new values.
871 1999-04-22 Gary Houston <ghouston@easynet.co.uk>
873 * ports.h (struct scm_port_table): add writing and reading members
874 to replace write_needs_seek: it isn't good enough for non-fports.
875 ports.c, ioext.c, fports.c: corresponding changes.
876 (struct scm_port_table): give it a typedef and rename to scm_port.
877 ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
878 corresponding changes.

888 * scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
889 signals (it was only being done for handlers installed from Scheme).
890 Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
891 waiting for input caused an EINTR error from read.
893 1999-04-07 Gary Houston <ghouston@easynet.co.uk>
895 * ports.h (struct scm_port_table): make all the char members
896 unsigned, so they convert to int without becoming negative if large.
898 1999-03-14 Gary Houston <ghouston@easynet.co.uk>
900 * fports.c (scm_fdes_wait_for_input): forgot to check compilation
901 with threads enabled. rename this procedure to
902 fport_wait_for_input and take a port instead of a fdes.
903 use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
905 * readline.c (scm_readline): Applied a patch from Greg Harvey to
906 get readline support working again: use fdopen to get FILE objects.
908 1999-02-26 Gary Houston <ghouston@easynet.co.uk>
910 * gc.c (scm_init_storage): install an atexit proc to flush the
912 (cleanup): the new proc. it sets a global variable which can be
913 checked by the ptob flush procs to avoid trying to throw
914 exceptions during exit. not very pleasant but it seems more reliable.
915 * fports.c (local_fflush): check terminating variable and if set
916 don't throw exception.
917 * CHECKME: that the atexit proc is installed if unexec used.
919 * throw.c (scm_handle_by_message): don't flush all ports here.
920 it still causes bus errors.
922 * fports.h (SCM_FPORT_CLEAR_BUFFERS): rename to SCM_CLEAR_BUFFERS
925 * fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
927 * ports.c (scm_char_ready_p): check the port buffer and call the
928 ptob entry if needed.
930 * ports.h (scm_ptobfuns): input_waiting_p added. change all the
931 ptob initialisers. use it in char-ready
933 * ioext.c (scm_do_read_line): moved from ports.c. make it static.
935 * vports.c (sfflush): modified to write a char (since softports
936 currently use shortbuf.)
938 * fports.c (scm_standard_stream_to_port): moved to init.c and
941 * init.c (scm_init_standard_ports): make stdout and stderr
942 unbuffered if connected to a terminal. with stdio they
943 were line-buffered by default.
945 (scm_ptobfuns): fputc, fputs, fwrite, fgetc, fgets removed.
948 * ports.h (scm_ptobfuns): change fflush return to void.
949 change flush proc definitions.
951 * strports.c (scm_call_with_output_string): get size from
952 buffer instead of port stream.
953 (st_flush): new proc.
955 * ports.h (struct scm_port_table): added write_end member,
956 as an optimisation. set it where write_buf_size is set.
958 * ports.h (struct scm_port_table): change stream from void *
959 back to SCM. SCM presumably must be large enough to hold a
960 pointer (and probably vice versa but who knows.)
961 (SCM_SSTREAM): deleted. change users back to SCM_STREAM.
963 (scm_puts): rewritten
964 * fports.c (local_ffwrite, local_fputs): removed.
965 * strports.c (stputc, stputs, stwrite): dyked out (FIXME)

976 * ports.h (scm_ptobfuns): add seek function pointer.
977 * fports.c: set it to local_seek, new procedure.
980 * fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
981 use ptob for seek. take ptob instead of fport arg.
983 * ports.h (struct scm_port_table): new member write_needs_seek,
984 replaces reading member in fport struct.
986 * vports.c (sfgetc): store the getted char into the buffer.
987 rename to sf_fill_buffer and install it for fill-buffer in ptob.
988 the Scheme interface is still a procedure that gets a char.
989 (scm_make_soft_port): set up the port buffer (shortbuf).
991 * fports.c (local_fgetc, local_fgets): deleted.
992 * strports.c (stgetc): likewise.
993 * ports.c: scm_generic_fgets: likewise.
995 * ports.h (scm_ptobfuns): add fill_buffer.
996 * ports.c (scm_newptob): assign it.

998 put just the string into the stream, not cons (pos stream).
999 (stfill_buffer): new proc.
1001 * ports.h: fport buffer moved into port table: to be
1002 used for all port types.

1011 scm_getpeername, scm_recv, scm_send, scm_recvfrom,
1013 use SCM_FPORT_FDES. use SCM_OPFPORTP not SCM_FPORTP.
1015 * posix.c (scm_getgroups): use SCM_ALLOW/DEFER_INTS.
1016 (scm_ttyname): use SCM_FPORT_FDES.
1017 (scm_tcgetpgrp, scm_tcsetpgrp): likewise.
1019 * filesys.c (scm_chown): use SCM_FPORT_FDES.
1020 (scm_chmod, scm_stat, scm_truncate_file: likewise.
1022 * ioext.c (scm_isatty_p): use SCM_FPORT_FDES.
1023 (scm_fdes_to_ports): modified.
1024 (scm_fdopen): use scm_fdes_to_port.
1026 * ports.c (scm_init_ports): don't try to flush ports using
1027 atexit(). it's too late, errors will cause SEGV.
1029 * fports.c (scm_fport_buffer_add): new procedure.
1031 * fports.h (SCM_FDES_RANDOM_P): new macro. use it in
1032 scm_fdes_to_port and scm_redirect_port.
1034 * ioext.c (scm_redirect_port): use setvbuf to set buffers in the
1035 new port. reset fp->random.
1037 * fports.c (scm_fdes_to_port), ports.c (scm_void_port),
1038 filesys.c (scm_opendir):
1039 restore defer interrupts while the port is constructed.
1040 * (scm_setvbuf): if mode is _IOFBF and size is not supplied,
1041 derive buffer size from fdes or use a default.
1042 (scm_fdes_to_port): use setvbuf instead of creating the buffers
1045 vports.c (various places): use SCM_SSTREAM.
1046 strports.c: likewise.
1047 * gdbint.c: likewise.
1048 * ports.h (SCM_SSTREAM): new macro.
1050 * fports.c (scm_input_waiting_p): use scm_return_first, since port
1051 may be removed from the stack by the tail call to scm_fdes_waiting_p.
1053 * fports.h (SCM_CLEAR_BUFFERS): new macro.

1197 * strop.c (scm_string_capitalize_x): Use the SCM object `s' in
1198 error messages, not the uninitialized string `str'. Love that
1201 * strop.c (scm_substring_move_x): New function, which can handle
1202 arbitrary overlapping substrings.
1203 (substring-move-left!, substring-move-right!): These are

1277 1999-03-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1279 * numbers.c (isfinite): Define this macro if not defined: Return a
1280 non-zero value if X is finite. (From ISO C 9x standard.)

1309 (scm_system_module_env_p): Assume root environment is no lookup
1312 * debug.c, eval.c, evalext.c, gdbint.c stacks.c:
1313 #include "modules.h".

1322 * error.c (scm_wta): Pass SCM_LIST1 (arg) instead of SCM_EOL to
1323 scm_misc_error when pos is a string. This allows for dispatching

1327 1999-03-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1333 1999-03-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1335 Most of this batch of changes is about how to deal with extended
1336 types when an object system is loaded into Guile. A nice object
1337 system is capable of representing Guile's types as class objects.
1339 For example, we want a regular expression to be of class <regex>.
1340 But regular expressions are smobs which aren't under direct
1341 control of the object system, so there has to be some mechanism
1342 which informs the object system that a new class should be created
1343 which can represent the smob type. I call this a "wrapper class".
1345 * objects.c: #include "smob.h";
1346 (scm_class_keyword): Removed. (Class is automatically created by
1348 (scm_smob_class): Array of smob classes indexed by smobnum.
1349 (scm_make_extended_class): "Plugin" function pointer for creation
1350 of wrapper classes for smob and struct types.
1351 (scm_class_of): Handle compiled closures. (Currently regarded as
1353 Use scm_smob_class to handle smob types;
1354 Handle scm_tc16_bigpos, scm_tc16_bigneg, and, scm_tc16_keyword
1355 through scm_smob_class;
1358 * smob.c (scm_newsmob): Also create a wrapper class if
1359 scm_smob_class has been initialized.
1361 * smob.h (SCM_TC2SMOBNUM): New macro for conversion between tc16
1362 type code and smobnum.
1364 * struct.c: #include "alist.h", "weaks.h", "hashtab.h";
1365 (scm_struct_table): Weak key table with auxilliary information for
1366 struct types. Currently used for names and wrapper classes.
1367 (scm_struct_ihashq): Hash function for structs.
1368 (scm_struct_create_handle): Get/create entry in scm_struct_table.
1369 (scm_struct_vtable_name, scm_set_struct_vtable_name_x): Procedures
1370 for accessing names of vtables. The record implementation in
1371 boot-9.scm currently uses the setter to record the name of record
1372 types. When the object system is initialized, it can use this
1373 information to create wrapper classes with suitable names.
1374 (scm_init_struct): Allocate scm_struct_table.
1375 (scm_alloc_struct): Don't initialize scm_struct_i_tag here.
1376 (struct tags are a finite resource and we might want to restrict
1377 the use of tags to vtables only. E.g., Goops only uses tags for
1379 (scm_make_struct): Use scm_struct_entity_n_extra_words instead of
1381 (scm_struct_vtable_tag): Use scm_struct_i_tag instead of magic
1384 * struct.h (SCM_STRUCT_TABLE_NAME, SCM_SET_STRUCT_TABLE_NAME,
1385 SCM_STRUCT_TABLE_CLASS, SCM_SET_STRUCT_TABLE_CLASS): New macros.
1386 Used for access of struct table entries.
1388 * hashtab.c, hashtab.h (scm_internal_hash_fold): New function.
1389 (scm_hash_fold): New procedure. Used to process all entries in a
1390 hash table (in no particular order).
1392 Argh! For the umpteenth time I got compilation errors because of
1393 the "intuitive" name `kw'. This has to have an end:
1395 * Makefile.am, init.c, libguile.h, objects.c, root.h: Replaced
1396 "kw" --> "keywords" everywhere.
1397 (I doubt that this will cause big compatibility problems since the
1398 application interface is unaffected.)
1400 * keywords.c, keywords.h: Files renamed from kw.c, kw.h.
1402 1999-03-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1404 * srcprop.c (scm_set_source_property_x): Bugfix: Convert line and
1405 column inums to native form.
1407 Improvement of backtraces: Introduces a new stack narrowing
1408 specifier, #t, for the inner cut. (See further in the comments in

1412 (Used to flag certain system procedures which shouldn't turn up in
1415 * eval.c (scm_sym_system_module): New symbol. (Used to flag
1416 modules which aren't "user" modules and the code of which

1420 Extract the lookup closure from an environment.

1427 * debug.c (scm_procedure_name): Use name property in the default
1430 * gc.c, gc.h (scm_object_address): Renamed from scm_object_addr ().
1432 * objects.h (scm_si_redefined, scm_si_hashsets): Shifted.
1434 * eval.c, procs.c, procs.h, procprop.c: Renamed getter ->
1435 procedure throughout.
1437 * print.c (scm_iprin1): Removed extraneous space when printing
1438 procedure-with-setters.
1440 Entity and operator setter slots were introduced as a complement
1441 to the <procedure-with-setter> type in order to support entities
1442 and operators with setters in a reasonable and efficient way.
1443 * procs.c (scm_procedure, scm_setter): Handle entity and operator
1446 * objects.h (SCM_OPERATOR_SETTER, SCM_ENTITY_SETTER): New macros.

1458 * objects.h (SCM_OBJ_CLASS_REDEF): New macro: Find class slots
1459 directly through the instance.
1461 * objects.c (scm_class_of): Use SCM_OBJ_CLASS_REDEF.
1463 * gc.c (scm_gc_sweep): Bugfix: Look for SCM_STRUCT_F_LIGHT flag at
1464 scm_struct_i_flags instead of scm_vtable_index_layout!
1466 * list.c (scm_list_star): New procedure.
1468 1999-02-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

1498 (scm_init_readline): Call init_bouncing_parens.

1551 1999-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1553 * print.c (scm_iprin1): Use scm_procedure_name instead of
1554 scm_procedure_property for compiled closures.
1556 * tags.h (scm_tc7_pws): New procedure type. Four representations
1557 for procedure-with-setters were considered before selecting this
1560 1. A closure where the CODE and ENV slots are used to represent
1561 the getter and a new SETTER slot is used for the setter. The
1562 original getter is stored as a `getter' procedure property. For
1563 closure getters, the CODE and ENV slots contains a copy of the
1564 getter's CODE and ENV slots. For subr getters, the CODE contains
1567 2. A compiled closure with a call to the getter in the cclo
1568 procedure. The getter and setter are stored in slots 1 and 2.
1570 3. An entity (i.e. a struct with an associated procedure) with a
1571 call to the getter in the entity procedure and the setter stored
1572 in slot 0. The original getter is stored in slot 1.
1574 4. A new primitive procedure type supported in the evaluator. The
1575 getter and setter are stored in a GETTER and SETTER slot. A call
1576 to this procedure type results in a retrieval of the getter and a
1577 jump back to the correct eval dispatcher.
1579 Representation 4 was selected because of efficiency and
1582 Rep 1 has the advantage that there is zero penalty for closure
1583 getters, but primitive getters will get considerable overhead
1584 because the procedure-with-getter will be a closure which calls
1587 Rep 3 has the advantage that a GOOPS accessor can be a subclass of
1588 <procedure-with-setter>, but together with rep 2 it suffers from a
1589 three level dispatch for non-GOOPS getters:
1591 cclo/struct --> dispatch proc --> getter
1593 This is because the dispatch procedure must take an extra initial
1594 argument (cclo for rep 2, struct for rep 3).
1596 Rep 4 has the single disadvantage that it uses up one tc7 type
1597 code, but the plan for uniform vectors will very likely free tc7
1598 codes, so this is probably no big problem. Also note that the
1599 GETTER and SETTER slots can live directly on the heap, using the
1600 new four-word cells.
1602 * procs.c, procs.h (SCM_PROCEDURE_WITH_SETTER_P, SCM_GETTER,
1603 SCM_SETTER): New macros.
1604 (scm_procedure_with_setter_p, scm_make_procedure_with_setter,

1629 * eval.h: Declare scm_s_set_x, scm_sym_set_x;
1631 * eval.c: Renamed "set" --> "set_x" in various names for
1632 consistency of name correspondence between Scheme and C;
1633 Renamed scm_i_set_x --> scm_sym_set_x and made global.
1634 Renamed s_set_x --> scm_s_set_x and made global.
1636 1999-01-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1638 * random.c (scm_i_random_bignum): Made independent of endianness.

1656 scm_rstate from seed.
1657 (scm_copy_random_state, scm_seed_to_random_state): New functions.
1658 (scm_make_random_state): Removed.
1660 * random.c (scm_make_random_state): Use scm_i_make_rstate().

1664 * random.c: Bugfix: Retrieve and store most significant 32 bits in
1665 different order if the machine is bigendian.

1668 1999-01-11 Roland Orre <mdj@mdj.nada.kth.se>
1670 * sort.c (scm_merge, scm_merge_list_x): Bugfix: Place elements
1671 from first arg before equal elements in second arg in result.
1672 (scm_merge_list_step): Bugfix: Don't presume that arguments in a C
1673 function call are executed in a well defined order.
1675 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
1677 * alloca.c (alloca): Cast value returned by malloc. (Thanks to
1680 1999-01-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1682 * random.c: Removed alloca includes.
1684 1999-01-11 Jim Blandy <jimb@zwingli.cygnus.com>
1686 * Makefile.in: This changed, for some reason I don't really
1687 understand, when I ran automake in the top level directory. This
1688 may be contamination by Cygnus internal releases. If you re-run
1689 automake and this change gets reverted, don't worry about it.
1691 1999-01-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1693 * sort.c, sort.h: New files: Implement slib's and scsh's sort
1694 interfaces. Author: Roland Orre.

1698 * init.c: #include "sort.h";
1699 (scm_boot_guile_1): Call scm_init_sort ().
1701 * numbers.h: Added #include "libguile/print.h".
1703 * numbers.c: Formatted according to Guile conventions;
1704 Renamed s_bignum --> scm_s_bignum.
1706 * random.c, random.h: New files: Random number support.
1707 Interface same as slib's.
1709 * Makefile.am: Added random.c, random.h, random.x.
1711 * init.c: #include "random.h";
1712 (scm_boot_guile_1): Call scm_init_random ().
1714 1998-12-23 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1716 * Makefile.am: New files: guardians.c, guardians.x, guardians.h
1718 * guardians.c, guardians.h (scm_make_guardian,
1719 scm_guardian_gc_init, scm_guardian_zombify, scm_guard,
1720 scm_get_one_zombie, scm_init_guardian): This is an implementation
1721 of guardians as described in R. Kent Dybvig, Carl Bruggeman, and
1722 David Eby (1993) "Guardians in a Generation-Based Garbage
1723 Collector" ACM SIGPLAN Conference on Programming Language Design
1724 and Implementation, June 1993 ftp://ftp.cs.indiana.edu
1725 /pub/scheme-repository/doc/pubs/guardians.ps.gz
1726 Author: Michael N. Livshin.
1728 * gc.h (SCM_MARKEDP, SCM_NMARKEDP): New macros.
1730 * gc.c (scm_igc): Call scm_guardian_gc_init and
1731 scm_guardian_zombify.

1735 1998-12-19 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1737 * macros.c (scm_makacro, scm_makmacro, scm_makmmacro): Added
1740 1998-12-15 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1742 Move the procedure slots of entities to invisible slots (so that
1743 we can have operator class objects which themselves are entities).
1744 * struct.h (scm_struct_i_proc, scm_struct_i_flags,
1745 SCM_STRUCTF_ENTITY): New constants.
1747 * struct.c (scm_make_struct): Allocate "invisible" room for
1748 procedures if SCM_STRUCTF_ENTITY is set in vtable.
1750 * gc.c (scm_gc_mark): Mark entity procedures.
1752 * struct.c, struct.h (scm_alloc_struct): Renamed from alloc_struct
1754 (scm_struct_init): Renamed from init_struct and made global.

1757 (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_0,
1758 SCM_ENTITY_PROC_3): Adjusted for new location of procedure slots.
1760 Mon Dec 14 18:10:12 1998 Maciej Stachowiak <mstachow@mit.edu>
1762 * snarf.h (SCM_SYNTAX): New macro to allow convenient declaration
1763 of syntactic forms, similar to SCM_PROC.
1764 * debug.c, eval.c, evalext.c: use SCM_SYNTAX to declare all special
1765 forms, and SCM_SYMBOL or SCM_GLOBAL_SYMBOL to delcare C variables
1766 for the name symbols when needed.
1768 1998-12-14 Jim Blandy <jimb@zwingli.cygnus.com>
1770 * Makefile.in: Regenerated.
1772 1998-12-05 Jim Blandy <jimb@zwingli.cygnus.com>
1774 * pairs.h (SCM_NEWCELL): When DEBUG_FREELIST is defined, don't
1775 take the address of _into; it might be a register. Just have
1776 scm_debug_newcell return the new cell.
1777 * gc.c (scm_debug_newcell): Just return the new cell, instead of
1778 taking the address of a place to store it as an argument.
1779 * gc.h (scm_debug_newcell): Change declaration.
1780 (Thanks to Greg Harvey.)
1782 1998-12-08 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1784 * ramap.c (array-copy-in-order!, array-map-in-order): New names.
1785 Replaces old names serial-array-copy! and serial-array-map!.

1791 * smob.c (freeprint): New function.
1792 (freecell): Use it to print freed objects, for slightly easier
1795 1998-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1797 * backtrace.c (display_frame): Made more robust. Doesn't throw an
1798 error if no source properties can be found for a frame. (Thanks
1799 to Christian Lynbech.)
1801 1998-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1803 * objects.h: Removed slots direct_supers and direct_slots from the
1804 definitions of the rudimentary classes described by objects.h.
1806 * objects.c, objects.h (scm_entity_p): New procedure. Together
1807 with the predicates scm_procedure_p and scm_struct_p, this
1808 predicate makes it possible to differ between structs, entities
1811 * modules.c, modules.h (scm_resolve_module): New function.
1813 1998-11-26 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1815 * objects.h (SCM_METACLASS_STANDARD_LAYOUT,
1816 SCM_METACLASS_OPERATOR_LAYOUT): Removed slots `direct_supers' and
1819 * objects.c (scm_entity_p): New procedure.
1821 * procprop.c (scm_i_procedure_arity): Bugfix: Return correct value
1822 for asubrs, rpsubrs, lsubrs and lsubr_2s.
1824 1998-11-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1826 * procprop.h (scm_i_procedure_arity): Added declaration.
1828 * procprop.c (scm_i_procedure_arity): Made global; New code to
1829 handle operators and entities.
1830 (scm_procedure_property): No need to call scm_procedure_p since
1831 scm_i_procedure_arity now does all necessary type checking.
1832 Added #include "objects.h".
1834 * feature.c (scm_remove_hook_x): Bugfix: Changed reference to
1835 s_add_hook_x --> s_remove_hook_x.
1836 (scm_add_hook_x, scm_remove_hook_x): Hooks now takes arguments.
1837 Added #include "procprop.h"
1839 * feature.c, feature.h (scm_reset_hook_x): New procedure.
1840 (scm_make_hook): Optional argument defines number of arguments to
1842 (scm_make_named_hook): Take number of args as second arg.
1843 (scm_run_hook): Renamed from scm_run_hooks (old name defined in
1844 boot-9.scm for a while); First arg is the hook. The rest are
1845 arguments passed on to the hook procedures.
1847 1998-11-23 Jim Blandy <jimb@zwingli.cygnus.com>
1849 * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
1850 scm_logbit_p): Do the computation in ulongs. This is not as nice
1851 as doing it in bignums, but at least it's good enough for
1852 manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
1854 * regex-posix.c (scm_regexp_exec): Reliably mark unmatched
1855 subexpressions. (Thanks to Charbel Jacquin.)
1857 1998-11-23 Mikael Djurfeldt <mdj@kenneth>
1859 * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
1860 scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
1861 (scm_make_named_hook): New function.
1863 * feature.c: Added #include "eval.h".
1865 * modules.c (scm_make_module): Beautify the module.
1867 1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1869 * modules.c, modules.h: New files: C interface to modules. (This
1870 is necessary in order to interface the object system to Guile
1871 properly. The guts of these modules will be replaced by the new
1872 module system in the future.)
1874 * init.c: Added #include "modules.h"
1875 (scm_boot_guile_1): Call scm_init_modules.
1876 (invoke_main_func): Call scm_post_boot_init_modules.
1878 * Makefile.am: Added modules.c, modules.x, modules.h.
1880 1998-11-22 Mikael Djurfeldt <mdj@kenneth>
1882 * procs.c: #include "objects.h"
1883 (scm_procedure_p): Return #t also on structs which are operators.
1885 * objects.c (scm_init_objects): Renamed <standard-metaclass>,
1886 <operator-metaclass> and <entity-class> to <standard-class>,
1887 <operator-class> and <entity> in order to conform with STKlos
1890 * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
1891 which isn't an operator.
1892 (SCM_APPLY): Ditto, but jump to badproc.
1894 1998-11-21 Mikael Djurfeldt <mdj@kenneth>
1896 * eval.c (SCM_CEVAL): Allow structs implanted in code.
1897 Previously, structs implanted in code were interpreted as forms
1898 the operator of which was a gloc. We solve this by checking for
1899 the zero in the emulated vcell in the struct vtable. Since
1900 implanted structs always will look like forms with a gloc
1901 operator, execution will only be slowed down by maximally one
1902 extra test-and-branch per application.
1904 * evalext.c (scm_definedp): Removed check for isyms; Added a
1905 second optional argument: It is now possible to supply an
1906 evaluation environment in which to look for the symbol.
1908 1998-11-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1910 * readline.c (scm_init_readline): Set
1911 rl_basic_word_break_characters. (Thanks to Ian Grant.)
1913 * coop.c (coop_condition_variable_wait): Removed
1914 (coop_condition_variable_wait_mutex): Folded logic of
1915 coop_mutex_unlock into coop_condition_variable_wait_mutex to
1916 prevent condvar signal lossage. Previously, another thread could
1917 start to run after unlocking the mutex but before putting the
1918 current thread on the wait queue. If that thread then would
1919 signal the first, the signal would be lost. (Thanks to Christian
1922 1998-11-17 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1924 * eval.c (SCM_CEVAL): Added missing case for cclo. (Thanks to
1927 1998-11-14 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1929 * objects.c (scm_i_make_class_object): Renamed from
1930 make_class_object; exported; error checking moved to
1931 scm_make_class_object and scm_make_subclass_object.
1932 (scm_make_class_object, scm_make_subclass_object): Use
1933 scm_i_make_class_object.
1934 (scm_make_subclass_object): Let the subclass have same metaclass
1937 1998-11-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1939 * debug.c (scm_debug_options): Bugfix: Set the value of
1940 scm_stack_checking_enabled_p after setting debug options;
1941 #include "stackchk.h". (Thanks to Richard Polton.)
1943 1998-11-13 Radey Shouman <rshouman@metro2000.com>
1945 * unif.c (scm_array_contents): removed unnecessary test for 0
1948 1998-11-13 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1950 * evalext.c, evalext.h (scm_m_sequence_to_list): Removed.
1951 Replaced by macro `collect' in boot-9.scm.
1953 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1955 * eval.c (scm_copy_tree): Copy source properties if existent.
1957 * debug.c (scm_start_stack): Copy source when evaluating. (If we
1958 don't, we may end up passing memoized source to a transformer.)
1960 1998-11-10 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
1962 * stack.c (get_applybody): Help function which lookups the first
1963 body form of the apply closure.
1964 (read_frames): Prevent the source of the first form of the apply
1965 closure from being recorded. This would only be confusing.
1967 * debug.h (SCM_SET_MACROEXP, SCM_CLEAR_MACROEXP, SCM_MACROEXPP):
1968 Replaces SCM_MACROFRAME, SCM_MACROFRAMEP.
1970 * eval.c (SCM_CEVAL): Use SCM_SET/CLEAR_MACROEXP.
1972 * stacks.c (read_frame): Bugfix: Removed lingering `else'
1974 (read_frames): Use SCM_MACROEXPP.
1976 1998-11-10 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1978 * stacks.c (read_frames): Skip gsubr frames in backtraces. (They
1979 don't contain interesting information since all arguments are
1980 present in the frame which applies the compiled closure anyway.);
1981 Skip the transformer application frames.
1983 * print.c (scm_iprin1): Print gsubrs as primitives.
1985 1998-11-09 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
1987 * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
1989 * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
1990 that we can identify these in a backtrace. (This change doesn't
1991 introduce any significant speed penalty.)
1993 * eval.c: Added note about `serial-map' using scm_map.
1995 * read.c, read.h (scm_read_options, scm_read_opts): Removed
1996 readline options. They should reside in their own options array.
1998 * readline.c, readline.h (scm_readline_options,
1999 scm_readline_opts): Moved readline options here.
2001 1998-11-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2003 * readline.c (scm_read_history, scm_write_history): Bugfix: Use
2004 SCM_ROCHARS instead of SCM_CHARS.
2006 * ports.c (scm_unread_string): Bugfixes: Check for SCM_STRINGP,
2007 not SCM_ROSTRINGP; use SCM_ROUCHARS instead of SCM_UCHARS.
2009 1998-11-06 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2011 * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
2012 This is quite important since the latter clears the
2013 FPORT_READ_SAFE and FPORT_WRITE_SAFE flags causing flushes at
2014 every single character read...
2016 1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2018 * print.c (scm_iprin1): Removed suspect looking (and indeed
2019 malevolent) semicolon after test for user supplied closure print
2020 procedure. (Thanks to Telford Tendys.)
2022 * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
2023 (scm_memq, scm_memv, scm_member): Do argument checking *before*
2024 starting to search the list. Removed call to sloppy_mem_check.
2026 * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
2027 procedures: Same as scm_delq_x et al, but delete maximally one
2030 * options.c (scm_options, scm_init_options): GC-protect option
2031 values of type SCM. (Thanks to Telford Tendys.)
2033 1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2035 * eval.c: Don't #define scm_lookupcar to scm_lookupcar1. Instead
2036 make sure that there always is a "real" scm_lookupcar.
2038 1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2040 * read.c, read.h (scm_read_opts): New read options
2041 "history-length" and "history-file".
2042 (scm_read_options): Stifle history to history length.
2044 * readline.c (scm_read_history, scm_write_history): New procedures.
2046 1998-10-31 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2048 * eval.h (scm_macro_eval_x): Removed declaration.
2050 * eval.c (scm_s_expression, scm_s_test, scm_s_body,
2051 scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
2052 Renamed and made global.
2054 * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
2055 (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
2057 * evalext.c, evalext.h: New files. Contain non-R5RS things
2058 having to do with evaluation.
2060 * evalext.c (scm_serial_map): New procedure: Version of `map'
2061 which guarantees that the procedure is applied to the lists in
2063 (scm_m_sequence_to_list): New syntax: Version of `begin' which
2064 returns a list of the results of the body forms instead of the
2065 result of the last body form.
2066 (scm_definedp, scm_m_undefine): Moved from eval.c
2068 * evalext.h (scm_m_sequence_to_list): Added declaration.
2070 * macros.c, macros.h: New files.
2071 (scm_procedure_to_syntax, scm_procedure_to_macro,
2072 scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
2073 scm_macro_name, scm_macro_transformer): Moved from eval.c
2074 (scm_make_synt): Moved from eval.c
2076 * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
2078 * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
2081 * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
2083 * debug.c, print.c: Added #include "macros.h".
2085 1998-10-29 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2087 This change adds the ability to use `unread-char' multiple times
2088 without interspersed reads and adds the new procedure
2089 `unread-string'. The change is optimized for the common case of
2090 unreading a single character. This is also the reason behind the
2091 choice to store characters in the port itself: in most cases no
2092 extra malloc is required.
2094 The amount of code in some macros in ports.h has been increased to
2095 the extent that they would fit better as C functions, but, since
2096 this code belongs to the port representation, such functions
2097 should be placed in ports.c which would cause calls back and forth
2098 between ports.c and genio.c. That is not good for performance.
2099 Also, keeping them as macros allows the compiler to do some
2100 optimizations which are needed to make the current interface
2101 (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
2103 One benchmark (Guile startup time) indicates an increase of
2104 loading speed of 1%. Another (reading (using `read') boot-9.scm
2105 10 times) shows no change in performance.
2107 (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
2108 made to find a beautiful solution.)
2110 * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
2111 (SCM_TRY_CLRDY): New macro: Only clear the first unread
2112 character. (SCM_CLRDY clears all.)
2113 (SCM_N_READY_CHARS): New macro: Returns number of unread
2114 characters in a port. Returns wrong answer if SCM_CRDYP is false.
2115 (struct scm_port_table): New fields: `entry' contains port table
2116 index, `cp' points to last unread char, `cbuf' is the buffer for
2117 unread chars, `cbufend' points after end of the character buffer.
2119 * ports.h, ports.c (scm_unread_string): New procedure.
2120 (scm_grow_port_cbuf): New function.
2122 * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
2124 (scm_generic_fgets), fports.c (local_fgets): Use a loop
2125 to read unread characters. Use SCM_TRY_CLRDY instead of
2128 * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
2130 * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
2132 * genio.c, genio.h (scm_ungets): New function.
2134 * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
2137 1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2139 * threads.h (scm_thread_sleep, scm_thread_usleep): Fixed
2140 declarations. (Thanks to Russ McManus.)
2142 1998-10-26 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2144 * numbers.c (num2long): As a software archeologist, I'm proud of
2145 this finding! :) Preliminary dating suggests an almost 4 year old
2146 remnant from the SCM ancestor. The sample has been removed from
2147 the finding site and is now safely stored in the repository.
2149 * numbers.h: Removed prototype for num2long.
2151 * unif.c (scm_array_set_x): Use scm_num2long instead of num2long.
2153 * gh_data.c (gh_scm2doubles): Make it possible to pass result
2154 array as second arg.
2155 (gh_chars2byvect, gh_shorts2svect, gh_floats2fvect, gh_scm2chars,
2156 gh_scm2shorts, gh_scm2longs, gh_scm2floats): New functions.
2157 * gh.h: Updated and added prototypes.
2159 * gh_data.c (gh_ints2scm): Handle integers outside INUM limits.
2161 1998-10-24 Jim Blandy <jimb@zwingli.cygnus.com>
2163 * gc.h: Remove all uses of SCM_P. (Thanks to Richard Polton.)
2165 * guile-snarf.in: Never generate an empty file. (Thanks to
2168 * gh.h (gh_enter, gh_new_procedure0_0, gh_new_procedure0_1,
2169 gh_new_procedure0_2, gh_new_procedure1_0, gh_new_procedure1_1,
2170 gh_new_procedure1_2, gh_new_procedure2_0, gh_new_procedure2_1,
2171 gh_new_procedure2_2, gh_new_procedure3_0, gh_new_procedure4_0,
2172 gh_new_procedure5_0): Specify argument types, to appease C++
2173 compilers. (Thanks to Brad Bowman.)
2175 Bug reports from Russ McManus:
2176 * guile-snarf.in: If the CPP environment variable is set, use that
2177 as the C preprocessor, instead of the preprocessor autoconf
2179 * snarf.h (SCM_PROC): Cast the function pointer passed to
2180 scm_make_gsubr, to satisfy C++.
2182 * gh_eval.c (gh_eval_str_with_catch, gh_eval_file_with_catch):
2183 Use the handler passed, instead of ignoring it and using
2184 gh_standard_handler. (Thanks to Etienne Bernard.)
2186 1998-10-20 Jim Blandy <jimb@zwingli.cygnus.com>
2188 * ports.h: Put text after #endif in comment. (Thanks to Nicolas
2191 1998-10-19 Jim Blandy <jimb@zwingli.cygnus.com>

2208 vectors.c, vectors.h, version.h, vports.c, weaks.c: Update
2211 * script.c (scm_compile_shell_switches): Define
2212 use-emacs-interface in the root module, so the repl code can see
2213 it. See today's change to top-repl in ice-9/boot-9.scm.
2215 * filesys.c (set_element, get_element): Make sure that `element'
2216 is a cell before applying SCM_FPORTP to it. (Thanks to Jost
2217 Boekemeier and Jorgen "forcer" Schaefer.)
2219 1998-10-18 Jim Blandy <jimb@zwingli.cygnus.com>
2221 * chars.c (scm_charnames): In ASCII character name table, make
2222 newlines print as #\newline by default, not #\nl.
2224 * Makefile.am (libguile_la_SOURCES, BUILT_SOURCES): Put these in
2225 alphabetical order. Oh thrills. But it helps me know how far
2226 along in the compilation I am.
2227 * Makefile.in: Regenerated.
2229 1998-10-18 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2231 * unif.c (scm_raprin1): Changed print syntax for byte vectors from
2232 #bytes(...) to #y(...), and syntax for short vectors from
2233 #short(...) to #h(...). This may seem nutty, but, like the other
2234 uniform vectors, byte vectors and short vectors want to have the
2235 same print and read syntax (and, more basic, want to have read
2236 syntax!). Changing the read syntax to use multiple characters
2237 after the hash sign breaks with the conventions used in R5RS and
2238 the conventions used for the other uniform vectors. It also
2239 introduces complexity in the current reader, both on the C and
2240 Scheme levels. (The Right solution is probably to change the
2241 syntax and prototypes for uniform vectors entirely.)
2243 1998-10-17 Jim Blandy <jimb@savonarola.red-bean.com>
2245 Don't use local_fgets on sockets; ftell doesn't work on sockets.
2246 (Thanks to Jorgen "forcer" Schaefer.)
2247 * ports.h (SCM_NOFTELL): New flag.
2248 * fports.c (local_fgets): If it's set, use the generic fgets.
2249 * socket.c (scm_socket): Set SCM_NOFTELL on the ports we produce.
2251 1998-10-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2253 * script.c (scm_compile_shell_switches): Add handling of -q switch
2254 (inhibit loading of user init file).
2255 (scm_shell_usage): Add usage text for -q switch.
2256 (scm_compile_shell_switches): Always load user init file first if
2257 it is loaded at all.
2259 1998-10-16 Jim Blandy <jimb@zwingli.cygnus.com>
2261 * stime.c: The CPP hair to determine a value for CLKTCK is weird,
2262 and is now broken under NetBSD. I can't fathom what it's trying
2263 to do, so I've replaced it with something that I do understand,
2264 which seems to work, and which isn't broken on NetBSD. "Progress?
2265 You Decide." (Thanks to Perry Metzger.)
2267 * regex-posix.c (scm_regexp_exec): Add a cast to remove a
2268 signed/unsigned comparison.
2270 1998-10-15 Jim Blandy <jimb@zwingli.cygnus.com>
2272 Warning fixes from Greg Harvey:
2273 * unif.c (scm_array_set_x): initializer for pos
2274 * throw.c (scm_ithrow): added initializer for jmpbuf (SCM_UNDEFINED)
2275 * struct.c (scm_struct_ref, scm_struct_set_x): Added
2276 initializers for field_type, since EGCS so desparately wants to
2278 * debug.h (scm_make_gloc, scm_gloc_p, scm_make_iloc, scm_memcons,
2279 scm_mem_to_proc, scm_proc_to_mem, scm_debug_hang): Added prototypes
2280 when GUILE_DEBUG is defined.
2281 * dynwind.h (scm_wind_chain): Same.
2282 * ports.h (scm_pt_size, scm_pt_member): Same.
2283 * print.h (scm_current_pstate): Same.
2284 * procs.h (scm_make_cclo): Same.
2286 1998-10-14 Jim Blandy <jimb@zwingli.cygnus.com>
2288 Handle short and long long uniform arrays properly. (Thanks to
2290 * ramap.c (scm_ra_matchp, scm_array_fill_int, scm_array_index_map_x,
2291 raeql_1): Add cases for scm_tc7_svect (short vectors) and
2292 scm_tc7_llvect (long long vectors).
2294 Change the way libguile and boot-9.scm are timestamped, to try to
2295 get rid of these spurious mismatch warnings. Now both
2296 libguile/versiondat.h and ice-9/version.scm are generated directly
2297 by the configuration process, rather than having version.scm
2298 generated directly, and libguile/versiondat.h generated by the
2299 Makefile, which is generated by configure. It seems that
2300 sometimes the Makefile would change, but versiondat.h depends on
2301 Makefile.in, not Makefile, so it wouldn't get rebuilt.
2302 * Makefile.am (versiondat.h): Target removed; this is generated
2303 directly by the configure script now.
2304 (BUILT_SOURCES): Remove versiondat.h.
2305 * versiondat.h.in: New file, transformed by the configure script
2307 * Makefile.in: Regenerated.
2309 * (__scm.h, alist.c, eval.c, feature.c, gsubr.c, numbers.c,
2310 options.c): Rename RECKLESS -> SCM_RECKLESS, CAUTIOUS ->
2311 SCM_CAUTIOUS; this way, 1) there's only one version of each flag
2312 to define (we used to have both RECKLESS and SCM_RECKLESS), and 2)
2313 if we want to use them in a header file some day, we can. (Thanks
2314 to Michael Livshin.)
2316 * stime.c (scm_get_internal_real_time): Do the arithmetic using
2317 SCM numbers, so we won't have rollover problems; the range of a
2318 signed long in milliseconds is about 25 days. (Thanks to Karl
2321 Don't redefine sleep and usleep; fix this problem now.
2322 * coop.c (sleep, usleep): Remove declarations; we don't use or
2323 redefine these any more.
2324 (scm_thread_usleep, scm_thread_sleep): New functions which do the
2325 job of usleep and sleep in a thread-friendly way. We can use
2326 these in the rest of Guile. Define versions for systems both with
2327 and without iselect.
2328 * threads.h (scm_thread_usleep, scm_thread_sleep): New declarations.
2329 * scmsigs.c (usleep): Clean up oddities declaring usleep; since
2330 we're just using it, not redefining it, we can use a K&R style
2332 (sleep): Declare this, too, if the system hasn't.
2333 (scm_sleep, scm_usleep): Use scm_thread_sleep and
2334 scm_uthread_sleep if they're available; otherwise, just call the
2336 * scmconfig.h.in: Regenerated.
2338 * coop.c (scm_thread_sleep): Make `slept' an unsigned long.
2340 * coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
2342 1998-10-12 Jim Blandy <jimb@zwingli.cygnus.com>
2344 * threads.c: Doc fix.
2346 The argument type of usleep varies from system to system,
2347 as does the return type. We really shouldn't be redefining usleep
2348 at all, but I don't have time to clean that up before the 1.3.
2349 release. It's on the schedule for afterwards. (Thanks to Julian
2351 * coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
2353 * scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
2354 * scmconfig.h: Regenerated.
2356 * simpos.c (scm_software_type): Procedure deleted. This isn't the
2357 right way to handle system variation. Autoconf's approach is the
2359 * simpos.h (scm_software_type): Declaration deleted.
2361 * script.c (scm_find_executable): Don't test if unix is #defined
2362 here; first, NetBSD doesn't #define it, and second, it's the wrong
2363 way to go about these things. (Thanks to Perry Metzger.)
2364 (dld_find_executable): Delete this MSDOS support code. This isn't
2365 the way we want to support this; it needs to be rethunk at a
2368 * genio.c (scm_do_read_line): Don't just politely check that the
2369 line was either non-empty or EOF. Abort if it's empty and not
2372 1998-10-11 Jim Blandy <jimb@zwingli.cygnus.com>
2374 * scmconfig.h.in: Regenerated.
2376 * libguile.h: Don't omit the dynamic linking functions. (Thanks
2379 * genio.c (scm_do_read_line): Count lines correctly when the file
2380 doesn't end in a newline.
2382 1998-10-10 Jim Blandy <jimb@zwingli.cygnus.com>
2384 * genio.c (scm_do_read_line): Maintain the line count correctly.
2385 (Thanks to Harvey J. Stein and Greg Harvey.)
2387 * gc.c (scm_return_first): Remove #ifdef __STDC__ garbage; Guile
2390 * numbers.c (big2str): Protect t from garbage collection until
2391 we're done. (Thanks to Gary Houston.)
2393 1998-10-09 Jim Blandy <jimb@zwingli.cygnus.com>
2395 * Makefile.am (libguile_la_LDFLAGS): Increment shared library
2397 * Makefile.in: Regenerated.
2399 * fports.h (scm_setbuf0, scm_setvbuf, scm_setfileno,
2400 scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
2403 Do magic to mix reads and writes on stdio FILE-based ports.
2404 (Thanks to Christian Lynbech.)
2405 * fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
2407 (pre_read, pre_write): New functions.
2408 (local_fgetc, local_fgets, local_ffwrite, local_fputc,
2409 local_fputs): Call them.
2410 (local_fflush): Mark the port as ready for reading and writing.
2411 (scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
2412 flags on new port objects. This might not be accurate --- who
2413 knows what state the FILE * is in when we get it --- but it won't
2414 do extraneous calls to fflush or fseek, so it's no worse than the
2415 behavior before this change.
2416 * ports.h: Add comment.
2418 Centralize the creation of port objects based on stdio FILE * in
2419 fports.c; don't just throw them together anywhere.
2420 * fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
2421 what the rest of Guile wants. Don't set the revealed count;
2422 that's only appropriate for stdin, stdout, stderr.
2423 (scm_standard_stream_to_port): This function does set the revealed
2425 * init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
2426 not scm_stdio_to_port.
2427 * filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
2428 * fports.c (scm_open_file): Same.
2429 * posix.c (scm_pipe): Same.
2430 * socket.c (scm_sock_fd_to_port): Same.
2431 * ioext.c (scm_fdopen): Same.
2432 (scm_freopen): Moved from here to...
2433 * fports.c (scm_freopen): ... here. This is really something that
2434 munges the internals of an fport, so it should go here.
2435 * fports.h (scm_stdio_to_port): Adjust prototype.
2436 (scm_standard_stream_to_port, scm_freopen): New protoypes.
2437 * ioext.h (scm_freopen): Prototype removed.
2439 * filesys.c (set_element, get_element): This can work on both pipe
2440 and file ports, so use SCM_FPORTP to typecheck, instead of testing
2443 * scmconfig.h.in: Regenerated.
2445 Change the definition of the functions in scm_ptobfuns so that
2446 they get passed the port object, not the port's stream.
2447 * ports.h (scm_ptobfuns): Rename all `stream' arguments to `port'.
2448 * gc.c (scm_gc_sweep): Pass the port itself to the free function.
2449 * genio.c (scm_putc, scm_puts, scm_lfwrite, scm_fflush, scm_getc):
2450 Pass the port itself to the scm_ptobs function.
2451 * ports.c (scm_close_port, scm_force_output, scm_flush_all_ports,
2452 scm_generic_fgets): Same.
2453 (putc_void_port, puts_void_port, write_void_port, flush_void_port,
2454 getc_void_port, fgets_void_port, close_void_port): Just change the
2455 argument names; these functions don't really do anything.
2456 * fports.c (local_fgetc, local_fgets, local_fclose, local_fflush,
2457 local_fputc, local_fputs, local_ffwrite, local_pclose): Take the
2458 port as an argument, and use SCM_STREAM to get the stdio FILE *.
2459 Also, use prototyped definitions, and get rid of the extra
2461 (scm_fptob, scm_pipob): We don't need casts here any more.
2462 * strports.c (prinstpt): Use prototype declarations.
2463 (stputc, stwrite, stputs, stgetc): Take the port as an argument,
2464 and use SCM_STREAM to get the string info. Also, use prototyped
2465 definitions, and get rid of the extra declarations.
2466 * vports.c (sfputc, sfwrite, sfputs, sfflush, sfgetc, sfclose,
2469 * ports.h (scm_ptobfuns): Replace uses of SCM_P with a straight
2470 prototype; it's okay (preferred, even!) to use ANSI C in Guile.
2472 * fports.c (local_fgetc, local_fgets): Renamed from scm_fgetc and
2473 scm_fgets, for consistency.
2474 (scm_fptop, scm_pipob): References updated.
2476 1998-10-08 Jim Blandy <jimb@zwingli.cygnus.com>
2478 Include the source location in error messages for scripts.
2479 * init.c (scm_boot_guile_1): Use scm_internal_lazy_catch, so the
2480 stack is still there when we catch the error.
2481 * throw.c (handler_message): If we are handling an error with a
2482 message, then put together the proper arguments and call
2483 scm_display_error, instead of scm_display_error_message. That
2484 displays source location, if it can find it.
2486 1998-10-07 Jim Blandy <jimb@zwingli.cygnus.com>
2488 * gc.c (scm_unprotect_object): Change this so that calls to
2489 scm_protect_object and scm_unprotect_object nest properly.
2490 (scm_protect_object): Doc fixes.
2492 * strings.c (scm_string_set_x): Require the argument to be a
2493 writable string, not a substring or a symbol.
2494 * strings.h (SCM_RWSTRINGP, SCM_NRWSTRINGP): New predicates.
2495 (Thanks to John Redford and Charbel Jacquin.)
2497 * scmconfig.h.in: Regenerated; ../acconfig.h has changed.
2499 1998-10-07 Jim Blandy <jimb@totoro.red-bean.com>
2501 * eval.c (safe_setjmp): Remove this misunderstanding.
2502 (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Replace with references to
2505 1998-10-06 Jim Blandy <jimb@zwingli.cygnus.com>
2507 * libguile.h: Mark these as C declarations, for compilation by C++
2510 * snarf.h (SCM_PROC, SCM_PROC1): Remove very odd code in #ifdef
2511 __cplusplus clause. I seriously doubt this ever worked the way
2512 the author seems to have intended.
2514 1998-10-05 Jim Blandy <jimb@zwingli.cygnus.com>
2516 Utterly needless cleanups to hopelessly messy code.
2517 * ports.c: Doc fixes.
2518 (scm_fflush): Moved to ...
2519 * genio.c (scm_fflush): ... here, amongst all the other port
2520 method invocation functions.
2521 * genio.h, ports.h: The prototype moves too.
2523 1998-10-04 Jim Blandy <jimb@zwingli.cygnus.com>
2525 * backtrace.c (display_error_body): The current frame does not
2526 always have a parent frame; consider a function called directly
2527 from the MAIN_FUNC passed to scm_boot_guile. (Thanks to Maciej
2530 * alloca.c (alloca): Undo yesterday's changes, and simply call
2531 malloc directly for storage, and abort if we don't get what we
2532 want. The situation is much simpler --- just call malloc. Emacs
2533 has bizarre/evil requirements (signal handlers might malloc unless
2534 you set this global flag, so you have to set the flag around all
2535 calls to malloc) which we are certainly not going to conform to,
2536 so we can do the simple and obvious thing.
2538 * coop.c (coop_condition_variable_wait): Make this function
2539 static. It's only useful internally --- you should never just
2540 wait on a condition variable.
2541 * coop-defs.h (coop_condition_variable_wait): Delete prototype.
2543 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2545 * unif.c (scm_array_set_x): Accept any kind of number as an
2546 element for a uniform vector of doubles. This is more consistent
2547 with Scheme's view of numbers. (Thanks to Miroslav Silovic.)
2549 * alloca.c: Use scm_must_malloc to obtain storage. Hopefully this
2550 works; I can't conveniently test it myself. (Thanks to Dvid
2551 Tillman for the bug report.)
2553 * init.c: Doc fixes.
2555 * init.c (invoke_main_func): Load the startup files (boot-9.scm)
2556 from here, not from scm_compile_shell_switches (which is a pretty
2557 dumb place to do it).
2558 (scm_load_startup_files): New function.
2559 (scm_ice_9_already_loaded): Variable moved to here from script.c.
2560 * script.c (scm_compile_shell_switches): Don't load the startup
2562 (scm_ice_9_already_loaded): Variable moved.
2563 * init.c (scm_load_startup_files): Prototype for new function.
2564 * gh_init.c (gh_enter): Doc fix.
2566 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2568 Some anti-warning changes from Greg Harvey.
2569 * gh_data.c (gh_scm2doubles): Initialize m, to avoid compiler
2570 warnings when it doesn't understand our NORETURN declarations in
2572 * posix.c (scm_mknod): Similar.
2574 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2576 * posix.c (scm_getpwuid): If we can't find an entry, return our
2577 own message, instead of using scm_syserror --- the getpwMUMBLE
2578 functions don't set `errno' to anything interesting.
2580 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2582 Get rid of warnings from the cooperative threading system.
2583 * threads.h (scm_single_thread_p, scm_yield,
2584 scm_call_with_new_thread, scm_join_thread, scm_make_mutex,
2585 scm_lock_mutex, scm_unlock_mutex, scm_make_condition_variable,
2586 scm_wait_condition_variable, scm_signal_condition_variable): Add
2587 prototypes for these Scheme-visible functions.
2588 * coop-defs.h (coop_next_runnable_thread,
2589 coop_wait_for_runnable_thread_now, coop_wait_for_runnable_thread):
2590 Prototypes for these here, even though they're from iselect.c.
2591 (coop_condition_variable_wait, coop_join): Add prototypes.
2592 * coop-threads.c (scm_threads_free_thread, scm_threads_free_mutex,
2593 scm_threads_free_condvar): Make these smob functions static.
2594 * coop-threads.h (coop_init): Give this a real prototype.
2595 * coop.c: #include <unistd.h>, if we have it, for `usleep' and `sleep'.
2596 (coop_next_runnable_thread): No need to provide prototype; it's in
2599 * scmconfig.h.in: .detarenegeR
2601 * iselect.c, threads.c: Doc fixes.
2603 1998-10-03 Jim Blandy <jimb@zwingli.cygnus.com>
2605 * Makefile.in: Regenerated with a patched automake, to get
2606 dependency generation right when using EGCS.
2608 * inet_aton.c (inet_aton): Add prototype, to remove compiler
2609 warning. (Thanks to Robert Pluim.)
2611 * inet_aton.c (inet_aton): Reassure the compiler that the
2612 arguments to the <ctype.h> macros are all unsigned characters, not
2615 1998-10-03 Jim Blandy <jimb@savonarola.red-bean.com>
2617 Getting rid of more warnings...
2618 * iselect.c: Test for MISSING_BZERO_DECL, not DECLARE_BZERO; see
2619 today's change to ../configure.in.
2620 * scmsigs.c: Test for MISSING_USLEEP_DECL, not DECLARE_USLEEP.
2621 * scmconfig.h.in: Regenertaded.de.,.__
2622 * stime.c (strptime): Declare this, #ifdef MISSING_STRPTIME_DECL.
2623 (scm_localtime, scm_mktime): Use a const char * to manipulate the
2626 * readline.c: Doc fix.
2627 (rl_cleanup_after_signal, rl_free_line_state): Make these static.
2628 * readline.h (scm_filename_completion_function): Add prototype.
2629 (scm_init_readline): Make this into a prototype.
2631 * readline.c (scm_filename_completion_function): Use SCM_PROC to
2632 declare this, instead of calling scm_make_subr manually.
2634 1998-10-02 Jim Blandy <jimb@savonarola.red-bean.com>
2636 * readline.h (scm_init_readline): Add prototype for this.
2637 (scm_init_readline): Make this a real prototype.
2639 1998-09-30 Jim Blandy <jimb@zwingli.cygnus.com>
2641 Warning fixes from Maciej Stachowiak:
2642 * backtrace.h (scm_display_application, scm_backtrace): Add
2644 * debug.c (scm_m_start_stack): Make this function static.
2645 * fluids.h (scm_fluid_p): Add prototype.
2646 * procprop.c (scm_i_procedure_arity): Make this function static.
2647 * regex-posix.c (scm_regexp_error_msg): Make this function static.
2648 * regex-posix.h (scm_init_regex_posix): Use prototype, not K&R decl.
2649 * root.h (scm_dynamic_root): Add external prototype.
2650 * scmsigs.h (scm_usleep): Add external prototype.
2651 * script.h (scm_init_script): Use prototype, not K&R decl.
2652 * stacks.h (scm_stack_id): Add external prototype.
2653 * symbols.h (scm_sysintern0_no_module_lookup): Add external prototype.
2655 1998-09-30 Mark Galassi <rosalia@cygnus.com>
2657 * gh.h: took out the definitions of vset and vref, since they are
2658 replaced by the proper vector routines that correspond to the R4RS
2661 1998-09-29 Jim Blandy <jimb@totoro.red-bean.com>
2663 * snarf.h (SCM_VCELL_INIT, SCM_GLOBAL_VCELL_INIT): New macros;
2664 these are analogous to SCM_VCELL and SCM_GLOBAL_VCELL but take a
2665 third argument, a C expression that should result in a SCM value,
2666 which is used to initialize the variable. Reimplemented
2667 SCM_CONST_LONG in terms of SCM_VCELL_INIT. (Thanks to Maciej
2670 * version.h (scm_libguile_config_stamp): Add prototype.
2671 (From Maciej Stachowiak.)
2673 1998-09-26 Jim Blandy <jimb@zwingli.cygnus.com>
2675 * eval.c (scm_force): Assert that x is SCM_NIMP to fix segv when
2676 (force 9) is tried. (Thanks to Karl M. Hegbloom.)
2678 1998-09-06 Jim Blandy <jimb@zwingli.cygnus.com>
2680 * print.c (scm_iprin1): Rather than having one i, and using it in
2681 several places, declare a fresh i local to each block where it is
2682 used, and give it a signedness appropriate to its use in each case.
2683 (scm_iprlist): Same.
2685 * print.c (scm_iprin1): Add cast to avoid unsigned/signed
2686 comparison warnings.
2688 * print.c (ENTER_NESTED_DATA): Make i an unsigned long, to avoid
2689 signed/unsigned clashes.
2691 * posix.h (scm_tmpnam): Added prototype.
2693 * objects.h (scm_set_object_procedure_x, scm_make_class_object,
2694 scm_make_subclass_object): Add external prototypes.
2696 * numbers.c (scm_mkbig): Add cast, and note that signed/unsigned
2697 comparison is okay here.
2699 * numbers.c (scm_istr2int): Add cast; len is known to be positive.
2701 * numbers.c (scm_bigcomp): Clarify logic, and avoid relying on the
2702 (true, but confusing) fact that -1 == ((unsigned) 0 - 1).
2704 * numbers.c (scm_adjbig): Make nsiz an scm_sizet, to avoid mixing
2707 * load.c (swap_port): Make this function static.
2709 * load.c (scm_search_path): Make max_path_len and max_ext_len
2710 unsigned, since they're compared against string sizes.
2712 * load.c (init_build_info): Make i unsigned.
2714 * ioext.h (scm_read_line): Add prototype.
2716 * hashtab.c (scm_hash_fn_get_handle, scm_hash_fn_create_handle_x,
2717 scm_hash_fn_remove_x): Make hash bucket index local variable k
2718 unsigned. Use scm_ulong2num to pass it to SCM_ASSERT as
2719 accurately as possible.
2721 * gh_data.c (gh_set_substr): Add casts to avoid signed/unsigned
2722 comparisons, and range checking to make sure those casts are
2725 * stackchk.h (SCM_STACK_OVERFLOW_P): Change definition to avoid
2726 signed/unsigned comparisons.
2728 * smob.c (scm_numsmob): Make this an int, not an scm_sizet, to
2729 avoid signed/unsigned comparisons.
2730 * smob.h (scm_numsmob): Change extern declaration to match.
2732 * ports.c (scm_numptob): Make this an int, not an scm_sizet, to
2733 avoid signed/unsigned comparisons.
2734 * ports.h (scm_numptob): Change extern declaration to match.
2735 (scm_current_load_port, scm_set_port_line_x,
2736 scm_set_port_column_x): New prototypes.
2738 * gsubr.c (GSUBR_TEST): Don't #define this. Nobody's using the
2739 test code, and it causes warnings.
2741 * gh.h (gh_int2scmb, gh_uniform_vector_length,
2742 gh_uniform_vector_ref): Added prototypes.
2744 * Makefile.am (libguile_la_SOURCES): Include Scheme-level
2745 debugging support unconditionally. That's backtrace.c, stack.c,
2746 debug.c, and srcprop.c.
2747 (EXTRA_libguile_la_SOURCES): Omit those from here.
2748 * Makefile.in: Regenerated.
2750 1998-08-21 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2752 * options.c (scm_options): Bugfix: Allow empty list of options!
2754 * debug.c, debug.h (scm_single_step): Removed.
2755 (scm_with_traps): New procedure. This procedure could easily be
2756 written in Scheme but needs to be highly optimized.
2758 * eval.h, eval.c: New evaluator trap flag: SCM_TRAPS_P.
2760 * eval.c (SCM_CEVAL, SCM_APPLY): Removed resetting of trap flags.
2761 Check SCM_TRAPS_P before trapping.
2763 1998-07-30 Jim Blandy <jimb@zwingli.cygnus.com>
2765 Changes to avoid signed/unsigned comparison warnings.
2766 * gc.c (scm_mtrigger, scm_heap_size): Make these unsigned longs.
2767 (scm_gc_sweep): Make n and j local to the blocks they're used in,
2768 so they can have appropriate types for each application. Make i
2769 signed. Use initializers in some spots. I'll probably pay for
2771 (scm_must_malloc, scm_must_realloc): Use scm_sizet for size args.
2772 (scm_must_realloc): Make nm unsigned.
2773 (init_heap_seg): Make new_seg_index and n_new_objects signed.
2774 (scm_init_storage): Use prototype-style definition, and make the
2776 * gc.h (scm_heap_size, scm_mtrigger, scm_must_malloc,
2777 scm_must_realloc, scm_init_storage): Adjust prototype accordingly.
2779 * filesys.c (scm_readlink): Make local vars rv and size ints, to
2780 avoid signed/unsigned comparison warnings, and because the return
2781 value of readlink may be -1. Don't bother casting the third
2782 argument to readlink.
2784 * filesys.c (scm_dirname, scm_basename): Move these to their own
2785 page, at the end of the file.
2786 * filesys.h (scm_dirname, scm_basename): Add prototypes for these.
2788 * eval.h (scm_eval_options_interface): Add external prototype for this.
2789 * eval.c (scm_eval_options_interface): Use prototype-style def'n.
2791 * eval.c (scm_lookupcar1): Make this static.
2793 * dynl.h (scm_registered_modules, scm_clear_registered_modules):
2794 Make these prototype declarations, not K&R-style.
2796 * chars.c (scm_tables_prehistory): Add cast, to remove signed/
2797 unsigned comparison warning.
2799 * appinit.c: File removed. It had a single function in it, empty,
2800 whose reason for existence is explained in no documentation or
2801 comment. I think it's there as a default for some Tcl-style
2802 initialization, but Tcl abandoned that approach a while ago.
2803 * Makefile.am (libguile_la_SOURCES): Remove appinit.c.
2804 (BUILT_SOURCES): Remove appinit.x.
2805 * Makefile.in: Regenerated.
2807 1998-07-29 Jim Blandy <jimb@zwingli.cygnus.com>
2809 * Makefile.in: Regenerated using the last public version of
2810 automake, not the hacked Cygnus version.
2812 1998-07-28 Jim Blandy <jimb@zwingli.cygnus.com>
2814 Remove Totoro kludge.
2815 * Makefile.in, scmconfig.h.in: Regenerated.
2816 * init.c, readline.c: Don't check if TOTORO is #defined.
2818 1998-07-26 Jim Blandy <jimb@zwingli.cygnus.com>
2820 * Makefile.am: Adjust for new thread configuration system.
2821 (INCLUDES): Include the value of THREAD_CPPFLAGS.
2822 (guile_LDADD, check_ldadd): THREAD_LIBS_LOCAL has been renamed from
2824 (THREAD_LIBS): Definition deleted; automake will generate such
2825 things automatically.
2826 * Makefile.in: Regenerated.
2828 1998-07-23 Jim Blandy <jimb@zwingli.cygnus.com>
2830 Simplify smob and port marking; set the mark bit in the generic
2831 marking code, and make marker routines only responsible for
2832 turning up outgoing pointers.
2833 * gc.c (scm_gc_mark): Set the mark bit on ports and smobs here,
2834 before calling the marking function. Don't call the marking
2835 function if it's zero.
2836 * markers.c (scm_mark0): Just return #f. This function isn't
2837 necessary at all now, but it's harmless to call it. We'll leave
2838 it in so other folks' code doesn't croak at link time.
2839 (scm_markcdr): Don't call SCM_SETGC8MARK.
2840 * async.c (mark_async): Don't call SCM_SETGC8MARK.
2841 * dynl.c (mark_dynl_obj): Same.
2842 * root.c (mark_root): Same.
2843 * srcprop.c (marksrcprops): Same.
2844 * unif.c (markra): Same.
2845 * variable.c (scm_markvar): Same.
2846 * ports.c (scm_markstream): Same.
2847 (void_port_ptob): Specify zero for our marking function.
2848 * debug.c (debugobjsmob): Same.
2849 * dynwind.c (guardsmob): Same.
2850 * filesys.c (dir_smob): Same.
2851 * fluids.c (fluid_smob): Same.
2852 * fports.c (scm_fptob, scm_pipob): Same.
2853 * mallocs.c (mallocsmob): Same.
2854 * regex-posix.c (regex_t_smob): Same.
2855 * smob.c (freecell, flob, bigob): Same.
2856 * threads.c (thread_smob, mutex_smob, condvar_smob): Same.
2857 * throw.c (jbsmob, lazy_catch_funs): Same.
2859 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2861 * eval.c (scm_copy_tree): Reverted last change: `eval' uses
2862 scm_copy_tree on code in order not to let memoized code to leak
2863 out. Thus, scm_copy_tree needs to copy vectors as well since
2864 quasiquote can introduce evaluated code also inside vector
2867 1998-07-17 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2869 * eval.c (scm_copy_tree): Removed ability to copy vectors.
2871 * gh_data.c, gh.h (gh_ints2scm, gh_longs2ivect,
2872 gh_ulongs2uvect): New procedures. (Complements gh_doubles2scm and
2875 * unif.c: Say that ivect and uvect are of type signed and unsigned
2876 long instead of int in commentary so that it correctly describes
2879 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2881 * stime.c: Removed declaration of strptime. (It should be
2882 declared by the system headers. If it turns out that some systems
2883 don't, we'll handle that then.) (Thanks to Greg Troxel.)
2885 * stime.h: Renamed TIMEH --> STIMEH
2887 * backtrace.c (scm_display_error, scm_display_backtrace): In order
2888 to increase portability, don't use structure assignment.
2889 (Thanks to Nicolas Neuss.)
2891 * iselect.c: Use LONG_MAX instead of ULONG_MAX for increased
2893 (finalize_fd_sets): Added empty statement after last case label.
2894 (Thanks to Nicolas Neuss.)
2896 * gc.c (scm_igc): Changed //-comment into /*-comment. (Thanks to
2899 Sat Jul 11 22:08:21 1998 Mikael Djurfeldt <mdj@totoro.red-bean.com>
2901 * init.c, readline.c: OK, I won't have these readline.x bug
2902 reports anymore. We've had them since April. The current reason
2903 is a completely unintelligible failure of totoro.red-bean.com to
2904 do the test for rl_getc_function in libreadline correctly. This
2905 kludge overrides the test if we're on totoro so that the snapshot
2906 generation process can work.
2908 * readline.c: Define a strdup replacement if not existent on system.
2910 1998-07-12 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2912 * vectors.c, vectors.h (scm_make_vector): Removed third argument.
2913 This change makes scm_make_vector R5RS compatible. We cannot keep
2914 the third argument since people want to be able to deduce the form
2915 of the C function call only by looking at R5RS. (At the same time
2916 we have removed some unnecessary complexity!)
2918 * eval.c, filesys.c, fluids.c, gc.c, gh_data.c, init.c, kw.c,
2919 net_db.c, posix.c, print.c, regex-posix.c, scmsigs.c, socket.c,
2920 stime.c, symbols.c, unif.c, vectors.c, weaks.c: Removed third
2921 argument in call to scm_make_vector.
2923 1998-07-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2925 * numbers.h (SCM_NUM2DBL): New macro. Complements SCM_NUMBERP.
2926 This macro is useful in applications.
2928 1998-06-21 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2930 * load.c (scm_internal_parse_path): Renamed from scm_parse_path.
2931 (scm_parse_path, scm_search_path): New Scheme level procedures.
2933 * load.h (scm_internal_parse_path, scm_parse_path,
2934 scm_search_path): Declared.
2936 1998-06-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2938 * filesys.c (dirname, basename): New procedures.
2940 * init.c (scm_boot_guile_1): Removed condition around
2943 * dynwind.c: #include "genio.h"; #include "smob.h"; Implemented a
2944 new data type (guards) for representation of C level guards and
2945 data on the wind chain.
2946 (scm_internal_dynamic_wind): New function.
2948 * dynwind.h: Declare scm_internal_dynamic_wind.
2950 * root.h (scm_root_state): Added scm_cur_loadp.
2952 * root.c (mark_root): Added comment about cur_loadp.
2954 * load.c: #include "dynwind.h";
2955 (scm_primitive_load): Use scm_inner_dynamic_wind to update
2958 * init.c (scm_init_standard_ports): Initialize scm_def_loadp.
2960 * ports.c (current-load-port): New procedure.
2962 1998-06-09 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2964 * ioext.c (scm_isatty_p): Accept any kind of data as argument. If
2965 not a tty, return #f.
2967 * regex-posix.c (scm_regexp_exec): Free malloced memory. (Thanks
2968 to Julian Satchell and Roland Kaufmann.)
2970 * gh.h (gh_memv, gh_member): Fixed typos in macro definitions.
2971 (gh_write): Added declaration. (Thanks to Eiichi Takamori.)
2973 1998-06-07 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
2975 * debug.h, debug.c (scm_start_stack): New function. Implements
2976 the guts of old scm_m_start_stack.
2978 * debug.c (scm_m_start_stack): Use scm_start_stack.
2980 * init.c (scm_start_stack, scm_restart_stack): Renamed to
2981 start_stack and restart_stack. (These have static scope.)
2983 1998-05-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2985 * readline.c (rl_cleanup_after_signals, rl_free_line_state): New
2986 readline functions to come in release 2.3. (Thanks to Chet
2988 (handle_errors): Use the above functions.
2990 1998-05-12 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2992 * readline.c: Improvements for readline support: Handle errors
2993 better; Implement before-read-hook.
2995 1998-05-11 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
2997 * init.c (scm_boot_guile_1), readline.c: Test for
2998 HAVE_RL_GETC_FUNCTION instead of HAVE_LIBREADLINE. (Need to
2999 assure that we have version >= 2.1.)
3001 1998-05-11 Mikael Djurfeldt <mdj@kenneth>
3003 * readline.c (scm_readline): Defer interrupts while we're calling
3006 * readline.c (scm_add_history): Bugfix: Do strdup before giving
3007 away the string to add_history.
3008 (completion_function): Do completion for readline. (Thanks to
3010 (scm_filename_completion_function): New procedure: Filename
3012 (current_input_getc): New function. Use this one instead of
3013 standard getc from readline.
3015 * throw.c, throw.h (scm_handle_by_throw): New function: This
3016 handler throws errors to next handler on the dynwind chain.
3018 1998-05-09 Mikael Djurfeldt <mdj@kenneth>
3020 * scmsigs.c (scm_usleep): Bugfix: Don't define j if it isn't
3023 1998-05-03 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3025 * procprop.c (scm_i_procedure_arity): New function. Returns arity
3027 (scm_procedure_properties): Modified to return arity together with
3029 (scm_procedure_property): Added the read-only property `arity'.
3030 (scm_set_procedure_property_x): It is an error to set the `arity'
3033 * gsubr.h, gsubr.c: Moved macros from gsubr.c to gsubr.h and added
3034 prefix SCM_; Made f_gsubr_apply global and added prefix scm_.
3036 * procprop.h (scm_sym_arity): New symbol.
3038 * objects.c (scm_set_object_procedure_x): New procedure: Use this
3039 to set the dispatch procedure of an operator or entity object.
3041 * objects.h (SCM_METACLASS_OPERATOR_LAYOUT, SCM_ENTITY_LAYOUT):
3042 Made procedure slots read-only.
3044 * eval.c (SCM_CEVAL): Moved scm_tc7_contin case above
3045 scm_tcs_cons_gloc case in zero args switch; Fixed args
3046 construction for operators in scm_tcs_cons_gloc case in two args
3049 1998-05-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3051 * fluids.c: Removed use of assert.h (in order to avoid
3054 * Makefile.am (libguile_la_LDFLAGS): Added -export-dynamic.
3056 * dynl.c (maybe_drag_in_eprintf): Disabled through #ifdef 0.
3058 * eval.c (SCM_CEVAL): Do more thorough argument checking. This
3059 change makes the evaluator safer at the cost of evaluation speed.
3060 It handles the case when the user has added a non-immediate
3061 improper end of the application form, e.g., `(+ 0 . x)'.
3062 (Earlier only cases like `(+ 0 . 0)' were handled.) I've tried to
3063 minimize the extra cost as much as possible. The new code is
3064 enclosed in #ifdef CAUTIOUS regions. NOTE: This also fixes the
3065 problem with structs planted directly in the code (e.g. by a
3066 macro). This no longer causes segmentation fault. (Thanks to
3069 * eval.c, eval.h (scm_eval_args, scm_deval_args): Take one extra
3070 arg `proc' in order to be able to throw errors; New argument
3073 * Removed extra #include "debug.h"
3075 1998-04-25 Mikael Djurfeldt <mdj@kenneth>
3077 * scmsigs.c: Declare usleep as returning void on some systems.
3078 (scm_usleep): Return SCM_INUM0 on those systems. (Thanks to Julian
3081 * coop.c (usleep): Return void on some systems.
3083 1998-04-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3085 * Makefile.am (libguile_la_LDFLAGS): Removed redundant -rpath.
3087 * coop.c: Changed return type of usleep to int.
3089 * scmsigs.c (scm_usleep): New procedure; Declare usleep if it
3090 isn't found in the OS.
3092 * iselect.h: #define scm_internal_select select if GUILE_ISELECT
3093 isn't enabled. (Thought that I had made this change ages ago...)
3095 * iselect.c: Declare bzero if not defined by OS.
3097 1998-04-19 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3099 * dynl.c (scm_must_free_argv): Fixed memory leak due to negated
3100 condition. (Thanks to John Tobey.)
3102 * continuations.c (scm_make_cont), debug.c (scm_make_memoized,
3103 scm_make_debugobj), eval.c (scm_makprom): SCM_DEFER/ALLOW_INTS -->
3106 * __scm.h: Start the long-term project of moving to POSIX threads.
3107 Phase 1: Classification of all critical sections.
3108 (SCM_ENTER_A_SECTION, SCM_EXIT_A_SECTION): New macros: Delimiters
3109 for A sections. (See comments in __scm.h for details.)
3111 * dynl.c: Only check that HAVE_DLOPEN is defined before loading
3112 dynl-dl.c; Test on HAVE_LIBDLD instead of HAVE_DLD.
3114 1998-04-18 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3116 * Makefile.am (BUILT_SOURCES): Added cpp_err_symbols.c,
3117 cpp_sig_symbols.c, libpath.h and versiondat.h to BUILT_SOURCES
3118 (libpath.h, versiondat.h): Replaced dependency on Makefile with
3119 dependencies on $(srcdir)/Makefile.in
3120 $(top_builddir)/config.status in order to avoid circularity.
3122 * script.c (scm_compile_shell_switches): Bugfix: Don't discount i
3123 from argc if argc was 0 initially.
3125 * Makefile.am (Makefile.am): Replaced THREAD_LIBS --> GUILE_LIBS
3126 in generation of libpath.h.
3128 1998-04-15 Mikael Djurfeldt <mdj@nada.kth.se>
3130 * Makefile.am (libguile_la_LDFLAGS): Bumped version number of
3131 libguile from 2 to 3.
3133 1998-04-14 Mikael Djurfeldt <mdj@nada.kth.se>
3135 * Makefile.am: Added .x-dependencies to variable BUILT_SOURCES.
3137 1998-04-13 Mikael Djurfeldt <mdj@kenneth>
3139 * ports.c (scm_port_line, scm_set_port_line_x, scm_port_column,
3140 scm_set_port_column_x, scm_port_filename,
3141 scm_set_port_filename_x): Removed optional arguments. Added
3142 proper argument checking.
3144 * eval.c, eval.h, coop.c (scm_eval_stack, SCM_EVAL_STACK): Measure
3145 stack size in machine words.
3147 * unif.c (scm_uniform_vector_ref, scm_cvref, scm_array_set_x,
3148 rapr1): Use SCM_UCHARS instead of SCM_CHARS for strings. (Thanks
3149 to Ole Myren Röhne.)
3151 1998-04-12 Mikael Djurfeldt <mdj@kenneth>
3153 * socket.c: Check for HAVE_UNIX_DOMAIN_SOCKETS instead of
3154 UNIX_DOMAIN_SOCKETS. (Thanks to Lauri Alanko.)
3156 * gc.c (scm_gc_sweep): Count cells correctly. (Thanks to Ben
3159 * eval.c (SCM_CEVAL, SCM_APPLY): In SCM_IM_APPLY and in the
3160 procedure apply: Copy argument lists before pushing them unto the
3161 environment so that the environment won't get mutated due to
3162 manipulation of procedure arguments. This should perhaps be
3163 regarded as a temporary solution until someone finds a more
3164 efficient one. (Thanks to Maciej Stachowiak.)
3166 1998-04-10 Mikael Djurfeldt <mdj@kenneth>
3168 * script.c (scm_compile_shell_switches): Use "guile" as default
3169 zero arg if argc is NULL.
3171 1998-04-02 Mikael Djurfeldt <mdj@nada.kth.se>
3173 * script.c (scm_compile_shell_switches): Allow NULL argv if argc
3174 is zero. (Thanks to Dirk Herrmann.)
3176 1998-03-30 Mikael Djurfeldt <mdj@nada.kth.se>
3178 * ports.c (scm_add_to_port_table): First line is now line 0
3179 (was 1). (Interface changed according to suggestion by Per
3182 * backtrace.c (display_header): Add 1 to line and column numbers
3183 when presenting them to the user.
3185 * eval.h, eval.c, debug.h, debug.c (scm_evaluator_traps): Moved
3186 from debug.c --> eval.c
3188 * eval.h, eval.c (scm_eval_options_interface): New options
3190 (SCM_EVAL_STACK): New option: Size of newly created stacks,
3191 i.e. stacks for new threads.
3193 * coop.c (COOP_STKSIZE): Use SCM_EVAL_STACK.
3195 * eval.c (unsafe_setjmp): Removed with #if 0.
3197 * gsubr.c (scm_gsubr_apply): Added dummy return to avoid compiler
3200 * eval.c, numbers.c, unif.c, srcprop.c: Added a few curly braces
3201 to avoid compiler warnings.
3203 * dynl-dl.c (sysdep_dynl_func): Only define usymb if needed.
3205 1998-03-28 Mikael Djurfeldt <mdj@nada.kth.se>
3207 * throw.c (handler_message): Print message on current error port
3208 instead of default error port. (Thanks to Maciej Stachowiak.)
3210 Mon Mar 2 21:35:02 1998 Gary Houston <ghouston@actrix.gen.nz>
3212 * ports.c (scm_add_to_port_table): allocate in units of
3213 struct scm_port_table *, not struct scm_port_table.
3214 * posix.c (scm_close_pipe): remove the port from the port table
3216 Thanks to Rob Engle for both fixes.
3218 1998-02-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3220 * iselect.h, iselect.c, coop.c, coop-threads.c, coop-threads.h,
3221 coop-defs.h, throw.c, backtrace.c: Added new copyright year 1998.
3223 1998-02-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3225 * throw.h: Removed jmpbuf arg in scm_catch_body_t.
3227 * backtrace.c (display_error_body, display_backtrace_body),
3228 coop-threads.c (scheme_body_bootstrip, c_body_bootstrip),
3229 gh_eval.c (eval_str_wrapper, eval_file_wrapper), init.c
3230 (invoke_main_func), root.c (cwdr_body), throw.c (cwss_body,
3231 scm_body_thunk, hbpca_body): Removed the second jmpbuf arg on body
3234 * throw.c (scm_internal_catch, scm_internal_lazy_catch): Bodies
3235 don't receive the jmpbuf arg anylonger.
3236 (scm_catch): Don't accept a #f tag.
3237 (scm_throw): Check that key is a symbol.
3238 (scm_ithrow): Don't take a jmpbuf as key. Don't check key arg.
3240 Fri Jan 30 22:28:07 1998 Mikael Djurfeldt <mdj@kenneth>
3242 * async.c (async_pending): Removed declaration.
3244 1998-01-30 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3246 * dynwind.c (scm_wind_chain): New debug function.
3248 * coop-threads.c (scheme_launch_data, scheme_body_bootstrip,
3249 scheme_handler_bootstrip, scheme_launch_thread, c_launch_data,
3250 c_body_bootstrip, c_handler_bootstrip, c_launch_thread): Add an
3251 extra layer of functions around the body and handler of a thread.
3252 This extra layer makes sure that the handler is called in the
3253 dynamic context of the surround (= empty dynwind list), but under
3254 the *dynamic root* of the body. We can not use the dynamic root
3255 of the surround since that root belongs to another thread => stack
3256 is not handled correctly. It may seem ugly to use this extra
3257 layer, but the extra cost in terms of execution time is really
3258 negligible compared to the total amount of time required to create
3259 a thread, and it would reduce maintainability to duplicate the
3260 crucial and complicated steps performed by cwdr.
3262 * __scm.h (SCM_ASYNC_TICK): Removed thread switching code.
3263 (SCM_ALLOW_INTS): Added thread switching code before interrupts
3264 get re-enabled. The important effect of this is that interrupts
3265 are blocked during thread switching so that thread data structures
3266 don't risk getting messed up by an unfortunate signal.
3267 (SCM_REDEFER_INTS, SCM_REALLOW_INTS): It turned out that gcc-2.8.0
3268 seems to do more aggressive optimization which actually move
3269 instructions around in these macros in a fatal way. Therefore:
3270 Introduce Anthony's SCM_FENCE macro! (And I who thought he was
3271 just superstitious...)
3272 (SCM_TICK): Maybe do a context switch and take care of asyncs.
3273 This macro should be used instead of SCM_ASYNC_TICK since the
3274 latter doesn't do context switches any more.
3276 * eval.c (scm_eval, scm_deval), eq.c (scm_equal_p): Use SCM_TICK
3277 instead of SCM_ASYNC_TICK.
3279 * coop.c, iselect.c: Since thread switches are now performed with
3280 interrupts masked, we can't use the old mechanism of delivering
3281 signals immediately when they arrive. Signals must instead be
3282 delivered when the asyncs run *after* the end of the critical
3283 section in scm_internal_select. But this also means after context
3284 switch so that the signal will be delivered to a different thread.
3285 To avoid this, I have changed the protocol of
3286 coop_wait_for_runnable_thread and friends so that they are allowed
3287 to return the original thread. So, if a signal arrives during
3288 scm_internal_select, we won't any longer be forced do a context
3289 switch, but can remain in the same thread and deliver the signal
3292 * async.c, async.h (asyncs_pending): Renamed asyncs_pending -->
3293 scm_asyncs_pending and made it global.
3295 * iselect.c: Small fixes.
3297 * coop.c (coop_mutex_init, coop_mutex_lock, coop_mutex_unlock,
3298 coop_condition_variable_init, coop_condition_variable_wait,
3299 coop_condition_variable_signal): Changed return type from `void'
3300 to `int'. This is to adhere closer to the pthreads interface.
3301 This, in turn, is part of an attempt to provide C versions of the
3302 mutex and condition variable primitives which can be part of a
3303 frontend to COOP or pthreads.
3305 * coop.c (coop_mutex_destroy, coop_condition_variable_wait_mutex,
3306 coop_condition_variable_destroy): New functions.
3308 * coop-threads.c (scm_wait_condition_variable): Use
3309 coop_condition_variable_wait_mutex.
3311 * coop-threads.h, coop-defs.h (coop_q_t, coop_m, coop_c):
3312 Definitions moved to coop-defs.h.
3314 * coop-defs.h (scm_mutex_init, scm_mutex_lock, scm_mutex_unlock,
3315 scm_mutex_destroy, scm_cond_init, scm_cond_wait, scm_cond_signal,
3316 scm_cond_destroy): New C interface to mutecis and cond vars.
3318 1998-01-24 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3320 * error.c (scm_wta): Added support for SCM_ARG6 and SCM_ARG7.
3322 * iselect.c: Now several threads can wait on the same file
3323 descriptor. The behaviour is compatible with OS select: All
3324 threads waiting for the fd return with the same status.
3326 1998-01-23 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3328 * coop-threads.c, threads.h (scm_spawn_thread): New function.
3329 Can spawn a thread from application C code.
3331 1998-01-20 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3333 * gh.h, gh_data.c (gh_doubles2scm, gh_doubles2dvect,
3334 gh_doubles2scm): New functions.
3336 1998-01-15 Mark Galassi <rosalia@nis.lanl.gov>
3338 * gh_eval.c (gh_eval_str): cleanup -- threw out the old
3339 commented-out version of gh_eval_str()
3341 Sun Jan 4 02:23:36 1998 Gary Houston <ghouston@actrix.gen.nz>
3343 * socket.c (scm_bind): free soka after use.
3345 Sat Jan 3 20:55:07 1998 Gary Houston <ghouston@actrix.gen.nz>
3347 * stime.c (tzvar): new variable.
3348 (setzone, restorezone, scm_localtime, scm_mktime, scm_strftime):
3349 avoid memory leaks when allocating.
3351 1998-01-03 Jim Blandy <jimb@totoro.red-bean.com>
3353 * iselect.h: Some systems require <sys/types.h> to get the FD_SET
3356 * gc.c, tags.h: Doc fixes.
3358 1998-01-02 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3360 * eval.c (macro-eval!): Removed. This function was a design bug.
3361 It allowed memoized code to leak out to the scheme level. Most
3362 things that you could do with `macro-eval!' can be done with
3365 1997-12-20 Tim Pierce <twp@skepsis.com>
3367 * fports.c (scm_pipob): Use scm_generic_fgets for line i/o, since
3368 scm_fgets now depends on ftell(3) to know how many bytes were
3371 1997-12-15 Tim Pierce <twp@skepsis.com>
3373 * gh_data.c (gh_scm2newstr, gh_get_substr): Use RO macros for
3374 dealing with strings.
3376 1997-12-13 Tim Pierce <twp@skepsis.com>
3378 Make %read-line more suitable for implementing read-line efficiently.
3379 * ioext.c (scm_read_line): Strip the terminating newline from a
3380 string, and return a cons of the string and its terminator.
3382 * fports.c, fports.h (scm_fgets): Add `len' argument. The length
3383 of the string that is read is stored in this memory location.
3384 * ports.c, ports.h (scm_generic_fgets, fgets_void_port): Same.
3385 * genio.c, genio.h (scm_do_read_line): Update caller.
3386 * ports.h (scm_ptobfuns): Update typedef.
3387 * fports.c (scm_fptob, scm_pipob): Update struct.
3389 1997-12-08 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3391 * filesys.c (set_element): Return file descriptor.
3392 (fill_select_type): Return the highest file descriptor.
3393 (scm_select): Tell select about the highest file descriptor. On
3394 some systems the SELECT_SET_SIZE can be as much as 128 bytes.
3395 Therefore the extra overhead for calculating the maximum fd seems
3396 to be more than compensated. Is this correct? In any case,
3397 scm_internal_select will be much faster with this info.
3398 (scm_select, fill_select_type, set_element): Don't accept any kind
3399 of object in the file descriptor list or vector.
3401 1997-12-07 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3403 * iselect.c (finalize_fd_sets): Bugfix.
3405 1997-12-06 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3407 * filesys.c (scm_select): Don't use SCM_DEFER_INTS/SCM_ALLOW_INTS
3408 when using scm_internal_select (since we might switch to another
3411 Sun Dec 7 01:43:56 1997 Gary Houston <ghouston@actrix.gen.nz>
3413 * simpos.c (scm_system): always define: use sysmissing if not
3414 available. Check for HAVE_SYSTEM instead of _Windows (does
3415 Windows lack system or does it have an unusable one?).
3416 Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
3417 Let the argument be optional: if not supplied, call system(NULL).
3419 * ports.c (scm_close_port): relax the type check from OPPORTP to
3420 PORTP; closing a closed port is allowed.
3422 1997-12-04 Tim Pierce <twp@ppp39.Nantucket.net>
3424 * fports.c (scm_fgets): Return if the last char in a chunk is
3425 newline. When fgets returns a string whose length is `size-1', it
3426 is ambiguous whether a whole line was retrieved, so we must check
3427 explicitly whether a line terminator is present.
3429 1997-12-04 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3431 * print.h (SCM_COERCE_OUTPORT): Check that the object is a pair
3432 before taking the CDR. (Thanks to Harald Meland.)
3434 * filesys.c (scm_stat): Slightly optimized.
3436 Wed Dec 3 12:23:06 1997 Jim Blandy <jimb@totoro.red-bean.com>
3438 * ports.c (scm_close_port): Make sure the port is open before
3441 * guile-snarf.in: Pass args through to gcc in a way that preserves
3442 whitespace boundaries. (Thanks to Greg Badros.)
3444 1997-12-02 Tim Pierce <twp@skepsis.com>
3446 * stacks.c (scm_frame_procedure): Reverse the logic in the return
3447 statement. (Thanks to Doug Evans for pointing this out.)
3449 1997-12-01 Tim Pierce <twp@skepsis.com>
3451 * scmconfig.h.in: Regenerated for USCORE change in ../acconfig.h.
3453 Sun Nov 30 11:29:18 1997 Mikael Djurfeldt <mdj@kenneth>
3455 * coop-defs.h (struct coop_t): Renamed errno --> _errno to prevent
3456 errno macro expansion of this field name. (errno is a C
3457 preprocessor macro on some systems.)
3459 1997-11-29 Tim Pierce <twp@skepsis.com>
3461 * iselect.c: Doc fix.
3463 Sat Nov 29 01:16:53 1997 Mikael Djurfeldt <mdj@kenneth>
3465 * init.c (scm_start_stack): Removed initialization of
3466 scm_the_last_stack_var.
3468 * backtrace.h: Declare scm_the_last_stack_var.
3470 * backtrace.c: Define scm_the_last_stack_var.
3472 * root.c (mark_root): Don't mark the_last_stack_var.
3474 * root.h (scm_root_state): Removed the_last_stack_var.
3476 * throw.c: Added #include "fluids.h"
3477 (ss_handler): `the-last-stack' is now a fluid.
3479 * (backtrace.h, backtrace.c, throw.c): Renamed the_last_stack_var
3480 --> the_last_stack_fluid.
3482 * backtrace.c: Added #include "fluids.h"
3483 (scm_init_backtrace): Initialize `the-last-stack' to a fluid.
3484 (scm_backtrace): `the-last-stack' is now a fluid.
3486 * init.c (scm_boot_guile_1): Moved call to scm_init_backtrace
3487 after scm_init_fluids.
3489 1997-11-28 Tim Pierce <twp@skepsis.com>
3491 * iselect.c: #ifdef USE_THREADS around thread-related includes.
3493 * dynl-dl.c (sysdep_dynl_func): Check both USCORE and
3494 DLSYM_ADDS_USCORE to decide whether to add an underscore.
3496 1997-11-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3498 * iselect.c (coop_next_runnable_thread,
3499 coop_wait_for_runnable_thread): Disable interrupts so that no
3500 async is executed before a potential error_revive.
3501 (scm_internal_select): Disable interrupts during the parts of the
3502 code which manipulate the sleep queue and the file descriptors.
3504 1997-11-27 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3506 * Makefile.am: Added iselect.c and iselect.h.
3508 * coop.c (coop_qinit): Initialize fields used by
3509 scm_internal_select.
3510 (coop_qget, coop_qget, coop_tmp_queue): Made global.
3511 (coop_next_runnable_thread): If GUILE_ISELECT enabled, use
3512 replacement in iselect.c.
3513 (coop_mutex_lock, coop_condition_variable_wait, coop_abort,
3514 coop_join): If GUILE_ISELECT enabled, use
3515 coop_wait_for_runnable_thread instead of
3516 coop_next_runnable_thread.
3517 (usleep, sleep): New replacements for system functions if
3518 GUILE_ISELECT is enabled.
3520 * coop-threads.h: Declare coop_wait_for_runnable_thread.
3522 * coop-defs.h (coop_t): Added fields used by scm_internal_select.
3524 * filesys.c: Added #include "iselect.h". Moved FD-macros to
3525 iselect.h. Implement Scheme level `select' using
3526 scm_internal_select. (See NEWS.)
3528 * genio.c (scm_getc): Block with scm_internal_select. (See NEWS.)
3530 * init.c: Call scm_init_iselect.
3532 * iselect.h, iselect.c: New files. Implements
3533 scm_internal_select. (See NEWS.)
3535 1997-11-27 Tim Pierce <twp@skepsis.com>
3537 Fix a memory leak in scm_read_line and a type cast bug in the ptob.
3538 * fports.c (scm_fgets): Use malloc/free rather than scm_must_malloc
3539 and scm_must_free, since ultimately the string returned will be copied
3540 by scm_makfrom0str anyway. Also, read any characters that may have
3541 been pushed onto the port with scm_ungetc.
3542 * ports.c (scm_generic_fgets): Same as for scm_fgets.
3543 * ioext.c (scm_read_line): Free string after Guilifying it.
3544 * ports.h (scm_ptobfuns): fgets method returns a char *, not a char.

3552 1997-11-25 Mark Galassi <rosalia@cygnus.com>
3554 * gh_test_repl.c (main_prog): changed invocation of gh_repl() to
3555 gh_repl (argc, argv).
3557 1997-11-24 Mark Galassi <rosalia@nis.lanl.gov>
3559 * gh_init.c (gh_repl): modified gh_repl() to accept argc and argv
3560 and to invoke scm_shell().
3561 (gh_launch_pad): took out the loading of boot-9.scm from here,
3562 since it is probably best to let the user control that. In fact,
3563 gh_repl() now invokes scm_shell() which does that.
3565 1997-11-23 Mark Galassi <rosalia@cygnus.com>
3567 * gh_test_repl.c (main_prog): added argc and argv to the gh_repl()
3570 1997-11-22 Tim Pierce <twp@twp.tezcat.com>

3584 (gh_uniform_vector_ref): started implementing the uniform types in
3587 1997-11-06 Mikael Djurfeldt <mdj@nada.kth.se>
3589 * regex-posix.c (scm_free_regex_t): Return size of regex_t instead
3590 of 0; size_t --> scm_size_t. Thanks to Bernard Urban.
3592 1997-10-26 Mikael Djurfeldt <mdj@nada.kth.se>
3594 * scmconfig.h.in: Updated (HAVE_LIBTERMCAP was added when
3595 configure.in was changed).
3597 Sun Oct 26 02:20:11 1997 Jim Blandy <jimb@totoro.red-bean.com>
3599 * Makefile.am (modinclude_HEADERS): Include readline.h here.
3600 * Makefile.in: Regenerated.
3602 1997-10-25 Marius Vollmer <mvo@zagadka.ping.de>
3604 * print.h (SCM_COERCE_OPORT): Renamed to SCM_COERCE_OUTPORT. An
3605 OPORT is an `open' port, not an output port.
3607 * filesys.c (scm_close, set_element, get_element, scm_chown,
3608 scm_chmod, scm_stat, scm_truncate_file, scm_fcntl, scm_fsync): Use

3612 scm_port_column, scm_set_port_column_x, scm_port_filename,
3613 scm_set_port_filename_x, scm_port_mode,
3614 scm_close_all_ports_except, scm_set_current_output_port,
3615 scm_set_current_error_port): Likewise
3616 * ioext.c (scm_redirect_port, scm_dup_to_fdes, scm_freopen,
3617 scm_ftell, scm_fileno, scm_isatty_p, scm_primitive_move_to_fdes):
3619 * posix.c (scm_ttyname, scm_tcgetpgrp, scm_tcsetpgrp): Likewise
3620 * backtrace.c (display_backtrace_body): Likewise
3621 * fports (scm_setvbuf): Likewise
3622 * socket.c (scm_getsockopt, scm_setsockopt, scm_shutdown,

3629 Minor problems with substring-related tag changes.
3630 * symbols.h (SCM_SUBSTRP): Don't mask off the S bit; that's
3631 exactly what we want to leave in to detect substrings.
3632 (SCM_ROSTRINGP, ROUCHARS): Formatting tweaks.
3633 * tags.h: Fix diagrams and comments describing the S tag bit;
3634 remove vestigial remarks about the D tag bit.
3635 (SCM_TYP7, SCM_TYP7S): Rephrased for readability.
3636 * strings.c: Formatting tweaks.
3638 * load.c (scm_init_load_path): Check GUILE_LOAD_PATH environment
3639 variable first; then SCHEME_LOAD_PATH, with a warning message.
3640 (scm_parse_path): New function.
3641 * script.c: Doc fixes.
3643 Thu Oct 23 01:02:03 1997 Jim Blandy <jimb@totoro.red-bean.com>
3645 Readline support, from Daniel Risacher.
3646 * readline.c, readline.h: New files.
3647 * init.c: #include "readline.h".
3648 (scm_boot_guile_1): Call scm_init_readline, if we have it.
3649 * Makefile.am (libguile_la_SOURCES): Include readline.c.
3650 * Makefile.in: Regenerated.
3651 * scmconfig.h.in: Regenerated, after change to ../configure.
3653 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3655 * gh.h: gh_vector_set -> gh_vector_set_x
3657 1997-10-20 Mark Galassi <rosalia@nis.lanl.gov>
3659 * gh_data.c (gh_vector_set_x): changed name to make it consistent
3660 with the ! -> _x mapping when going from Scheme to C.
3662 1997-10-19 Mark Galassi <rosalia@cygnus.com>
3664 * gh.h (gh_reverse):
3672 (gh_assoc): added these gh_ functions implemented as macros.
3674 * gh_predicates.c (gh_null_p):
3675 (gh_string_equal_p): added these two missing predicates.
3677 * gh_list.c (gh_append):
3682 (gh_set_cdr_x): added these routines as I go through and try to
3683 complete the picture R4RS functions that should be mirrored in the
3686 Sat Oct 18 01:52:51 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3688 * tags.h (scm_tc7_substring): Changed the comment and code to
3689 conform with the changes below. Folks! We have suddenly two new
3690 free tc7 codes!!! Jummy, jummy!
3692 Tue Oct 14 22:03:06 1997 Tom Tromey <tromey@cygnus.com>
3694 * Makefile.in: Rebuilt.
3695 * Makefile.am (libguile_la_SOURCES): Removed extchrs.c,

3715 (scm_tc7_mb_string): Removed.
3716 (scm_tc7_mb_substring): Removed.

3719 Don't include "mbstrings.h".
3720 * symbols.c (scm_intern_obarray_soft, scm_string_to_symbol,
3721 scm_string_to_obarray_symbol, msymbolize): Don't set symbol's
3723 Don't include "mbstrings.h".
3724 * symbols.h (SCM_SYMBOL_MULTI_BYTE_STRINGP): Removed.
3725 (SCM_SYMBOL_SLOTS): Define as 4.

3727 * arbiters.c, backtrace.c, debug.c, dynl.c, eval.c, fluids.c,
3728 gc.c, gsubr.c, ioext.c, kw.c, mallocs.c, numbers.c, ports.c,
3729 print.c, read.c, regex-posix.c, root.c, srcprop.c, stackchk.c,
3730 struct.c, threads.c, throw.c, unif.c, variable.c: Use new

3747 * libguile.h: Don't include "extchrs.h" or "mbstrings.h"
3748 * extchrs.h, extchrs.c, mbstrings.h, mbstrings.c: Removed.
3750 1997-10-12 Mark Galassi <rosalia@cygnus.com>
3752 * gh_test_repl.c (c_vector_test): same as gh_test_c.c
3754 * gh_test_c.c (c_vector_test): some improvements on the vector
3757 * gh.h (gh_vector): this used to exist but do the wrong thing.
3758 Now it (almost) does the right thing, though it takes a list
3759 instead of the individual arguments. I need to see how it could
3761 (gh_list_to_vector): added this function as a macro. Corresponds
3762 to Scheme's (list->vector ...).
3763 (gh_vector_to_list): added this function as a macro. Corresponds
3764 to Scheme's (vector->list ...).
3766 * gh_data.c (gh_vector_ref): renamed from gh_vref to
3767 gh_vector_ref, so that it resembles the Scheme routines more.
3768 (gh_vector_set): renamed from gh_vset to gh_vector_set, so that it
3769 resembles the Scheme routines more.
3770 (gh_make_vector): this used to be (stupidly) called gh_vector().
3771 This is the right name, since it does the same thing as the Scheme
3772 (make-vector ...) procedure.
3774 Sun Oct 12 14:41:39 1997 Mikael Djurfeldt <mdj@kenneth>
3776 * ports.h: #include "libguile/print.h"
3778 * eval.c (SCM_CEVAL, scm_apply): Completed GOOPS support code;
3779 Some indentation fixes.
3781 * objects.h (SCM_METACLASS_STANDARD_LAYOUT): Printer field is no
3782 longer a user field; New field: class_flags.
3784 * objets.c, objects.h: New metaclass: scm_metaclass_operator.
3786 Tue Oct 7 09:37:24 1997 Mark Galassi <rosalia@cygnus.com>
3788 * gh_data.c (gh_bool2scm): new function which replaces
3789 gh_int2scmb(), which is now tagged as obsolete.
3791 1997-10-03 Mikael Djurfeldt <mdj@nada.kth.se>
3793 * print.h (SCM_PRINT_STATE_P): Removed SCM_NIMP test. (NIMP
3794 macros should by convention not test for NIMPness.)
3795 (SCM_COERCE_OPORT): Adjust indentation.
3797 * print.c (scm_valid_oport_value_p): Adjusted indentation; Added
3798 SCM_NIMP test before SCM_PRINT_STATE_P.
3800 * struct.c, struct.h, gc.c: Renamed:
3801 scm_struct_i_layout --> scm_vtable_index_layout
3802 scm_struct_i_vcell --> scm_vtable_index_vcell
3803 scm_struct_i_vtable --> scm_vtable_index_vtable
3804 scm_struct_i_printer --> scm_vtable_index_printer
3805 scm_struct_i_vtable_offset --> scm_vtable_offset_user
3807 * struct.c (scm_print_struct): Use new printer slot; Default
3808 printing: Also output hex code of vtable so that type identity
3809 will be indicated as well.
3810 (scm_init_struct): Updated required_vtable_fields to "pruosrpw";
3811 Removed struct_printer_var; Removed struct-vtable-offset;
3812 (vtable-index-layout, vtable-index-vtable, vtable-index-printer,
3813 vtable-offset-user): New constants.
3815 * struct.h (scm_struct_i_vtable_offset): Bumped from 3 to 4.
3816 (scm_struct_i_printer, SCM_STRUCT_PRINTER): New slot in vtables.
3817 If this slot contains a procedure, use that to print structures of
3818 the type represented by this vtable.
3820 * print.c (scm_iprin1): Don't print arguments of macro
3821 transformers. (They are always: exp env.); Bugfix: Unmemoize
3822 transformer source with correct environment.
3824 1997-10-02 Marius Vollmer <mvo@zagadka.ping.de>
3826 Streamlining of call-with-dynamic-root:
3828 * root.c (cwdr_inner_body, cwdr_body): Remove "inner" from name,
3829 there is now only one catch.
3830 (cwdr_outer_body): Removed.
3831 (cwdr_handler): New function.
3832 (scm_internal_cwdr): New function to perform the function of cwdr
3833 but take args that are more useful to C code. Also, the handler
3834 is now invoked *outside* of the new dynamic root, like the docs
3835 say. We no longer have to catch absolutely all errors, the caller
3836 is responsible for using a handler that does not throw, if he
3838 (cwdr): Reimplemented in terms of scm_internal_cwdr.
3839 * root.h (scm_internal_cwdr): New prototype.
3841 Even more but risky streamlining:
3843 * root.c (USE_STACKJMPBUF): New define to activate a stack-based
3844 allocation of the jumpbuf of a root continuation. The changes
3845 below are controlled by it. They are now deactivated.
3846 (scm_internal_cwdr): Allocate the scm_contregs on the stack. Set
3847 the JMPBUF of the scm_rootcont to NULL before returning.
3849 * gc.c (scm_gc_sweep): Free the SCM_VELTS of a scm_tc7_contin only
3850 when they are non-NULL.
3851 (scm_gc_mark): Likewise, mark only when non-NULL.
3853 Make dynamic linking work on Dec Unix. (Thanks to Clark McGrew)
3854 * dynl.c: Include "dynl-dl.c" also when HAVE_DLOPEN is defined.
3856 * gc.c (scm_done_malloc): New function.
3857 gc.h (scm_done_malloc): New prototype.
3859 * print.h (SCM_PRINT_STATE_P, SCM_COERCE_OPORT): New macros.

3866 a certain value is acceptable as a port argument.
3867 (scm_print_state_vtable): New variable.
3868 (scm_free_print_state): Set `revealed' field to false.
3869 (scm_iprin1): Call user supplied closure printer with
3870 scm_printer_apply. Print in the traditional way when there isn't
3871 one or when it returns #f.
3872 (scm_prin1, scm_display, scm_write, scm_newline, scm_write_char):
3873 Accept a port/print-state pair in addition to just a port.
3874 (scm_prin1): Don't return the print_state to the pool when it has
3876 (scm_printer_apply): Set `revealed' field of print_state to true.
3877 (scm_init_print): Set scm_print_state_vtable.
3878 (print_state_fluid, print_state_fluid_num): Removed.
3880 * throw.h (scm_handle_by_proc_catching_all): New prototype
3881 throw.c (scm_handle_by_proc_catching_all): New function
3883 Mon Sep 29 23:54:09 1997 Jim Blandy <jimb@totoro.red-bean.com>
3885 * Makefile.in: Regenerated with automake 1.2c.
3887 Sun Sep 28 21:35:42 1997 Radey Shouman <shouman@zianet.com>
3889 * ramap.c (scm_array_index_map_x): Fixed for zero-rank arguments,
3890 was looping endlessly.
3892 Sun Sep 28 00:04:29 1997 Jim Blandy <jimb@totoro.red-bean.com>
3894 * strports.c (scm_eval_string): Don't close the port.
3896 * stime.c (bdtime2c): Use SCM_LENGTH, not scm_vector_length; the
3897 former returns a nice normal integer. (Thanks to Daniel
3900 Sat Sep 27 20:19:34 1997 Jim Blandy <jimb@totoro.red-bean.com>
3902 * Makefile.am (libpath.h): Include the value of the THREAD_LIBS
3903 makefile variable as a build parameter called LIBS. The
3904 build-guile program will use this, for the time being.
3905 * Makefile.in: Regenerated.
3907 Thanks to Shiro Kawai:
3908 * gc.c (scm_gc_mark): Pass NULL to scm_wta as the subroutine name.
3909 * ports.h (scm_ptobfuns): The fgets method returns a char *, not
3912 * Makefile.in: Regenerated with automake 1.2a.
3914 * script.c (scm_compile_shell_switches): If we hit the -c or --
3915 arguments, don't set the car of (command-line) to scm_usage_name,
3916 the prettified name of the guile executable; give it the full
3917 path, the way shells usually handle $0.
3919 Wed Sep 24 22:09:52 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3921 * ramap.c (scm_array_map): Renamed to scm_array_map_x. Removed
3922 Scheme-level name `array-map' and renamed `serial-array-map' to
3923 `serial-array-map!'.
3925 * backtrace.c: Introduced exception handlers which now enclose
3926 `display-error' and `display-backtrace' so that error reporting
3927 won't get into infinite loops if an error occurs during displaying
3928 of the error. This can very easily happen with user supplied
3929 print call-back routines.
3931 Tue Sep 23 12:43:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3933 * ramap.c: Added alias `array-map!' for `array-map'. (Probably,
3934 the names `serial-array-map' and `array-map' should be removed.)
3936 Mon Sep 22 01:21:54 1997 Mikael Djurfeldt <mdj@kenneth>
3938 * init.c (scm_boot_guile_1): Added scm_init_objects ().
3939 Added #include "objects.h"
3941 * eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
3942 Add #include "feature.h".
3944 * Makefile.am (libguile_la_SOURCES): Added objects.c.
3945 (modinclude_HEADERS): Added objects.h.
3947 * ports.h (SCM_EOF_OBJECT_P): New macro predicate.
3948 This test is needed at many places in the code and should be
3949 abstracted. (Motivated by the need of this test in libguiletk.)
3951 * ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
3952 (scm_eval_string), load.c (scm_primitive_load,
3953 scm_read_and_eval_x), gh_eval.c (gh_eval_str):
3954 Use SCM_EOF_OBJECT_P.
3956 * eval.c (scm_init_eval): Add feature `delay'.
3958 Tue Sep 16 02:12:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3960 * scmhob.h: Removed.
3962 Mon Sep 15 20:42:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3964 * list.h (SCM_LISTn): New macros. Make list creation in C code
3965 prettier. The idea comes from STk.
3967 * sequences.h, sequences.c, append.h, append.c: Removed. These
3968 files implemented non-R4RS operations which would encourage
3969 non-portable programming style and less easy-to-read code.
3971 * Makefile.am (sequences.h, sequences.c, append.h, append.c):
3974 * libguile.h, eval.c, init.c, stime.c, unif.c: Removed #include
3975 sequences.h, #include append.h.
3977 * init.c (scm_boot_guile_1): Removed calls to scm_init_append and
3980 * gh.h, gh_list.c: Renamed gh_list_length --> gh_length.
3982 * list.h, list.c: Renamed scm_list_length --> scm_length, scm
3984 * stime.c (bdtime2c): Changed scm_obj_length --> scm_vector_length.
3986 Sat Sep 13 00:21:41 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3988 * eval.c: Added #include "objects.h"
3990 * tags.h (scm_tc16_object, scm_tc16_entity): Smobtags for objects
3993 * smob.c (scm_smob_prehistory): Create two objectsmobs with
3994 adjacent smob numbers.
3996 Thu Sep 11 00:59:17 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
3998 * procprop.h: Added declaration of scm_i_inner_name.
4000 * gsubr.c: New global symbol scm_i_inner_name.
4002 * debug.c (scm_procedure_name): Try procedure property
4003 `inner-name' if `name' fails.
4005 * print.c (scm_iprin1): Use scm_macro_name.
4007 * eval.c (scm_m_define): Give names to macros as well; Only the
4008 first top-level definition gives a procedure/macro a name.
4009 Otherwise confusing names can turn up in backtraces.
4010 (SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
4011 `name'; Give names to macros as well.
4013 * procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
4014 (scm_macro_transformer): Use SCM_CLOSUREP instead of
4017 Wed Sep 10 20:52:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4019 * eval.c (macro?, macro-type, macro-name, macro-transformer): New
4021 (prinmacro): Removed. The code has been moved/merged into print.c
4022 in order to decrease code redundancy. We want macros to print in
4023 a way equivalent to procedures, and it would be silly to duplicate
4024 the required code. (We don't want to maintain two places.)
4025 (macrosmob): Print field is now a NULL pointer.
4027 * eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
4028 scm_macro_transformer): New prototypes.
4029 (scm_tc16_macro): Declared.
4031 * print.c (scm_iprin1): Added code for printing of macros. Macros
4032 are now printed in a way equivalent to procedures.
4034 Sat Sep 6 12:20:42 1997 Mikael Djurfeldt <mdj@kenneth>
4036 * procs.h (scm_closure_p): Added declaration.
4038 Fri Sep 5 13:36:14 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4040 * gc.c (scm_gc_mark): Fixed "rogue pointer in heap" message:
4041 Shouldn't pass "heap" as the subr name.
4043 Tue Sep 2 18:14:30 1997 Jim Blandy <jimb@totoro.red-bean.com>
4045 * gh_predicates.c (gh_boolean_p, gh_symbol_p, gh_char_p,
4046 gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
4047 gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
4048 gh_equal_p): Use SCM_NFALSEP, instead of testing against
4049 SCM_BOOL_T. Any non-false value is true.
4051 Tue Sep 2 00:27:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4053 * symbols.h (scm_builtin_bindings, scm_builtin_weak_bindings,
4054 scm_gensym): Added prototypes.
4056 * symbols.c (scm_gensym): New function. This will speed up
4057 certain types of applications (such as macro systems) which
4058 generate lots of symbols.
4060 Mon Sep 1 22:30:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4062 * numbers.c (logand, logior, logxor): Handle 0 or 1 arguments.
4064 Sat Aug 30 18:56:19 1997 Gary Houston <ghouston@actrix.gen.nz>
4066 * unif.c (scm_shap2ra): tighten the checking of the array dimension
4067 specifier, since (2) or (2 . 3) would cause SEGV.
4068 (scm_transpose_array): more argument checking fixes.
4070 Thu Aug 28 23:48:53 1997 Jim Blandy <jimb@totoro.red-bean.com>
4072 * Makefile.in: Regenerated.
4074 Wed Aug 27 17:44:44 1997 Jim Blandy <jimb@totoro.red-bean.com>
4076 * Makefile.in: Regenerated, so it uses "tar", not "gtar".
4078 Mon Aug 25 13:47:25 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4080 * error.c, error.h (scm_error_callback): Removed (see NEWS).
4082 Sun Aug 24 01:25:35 1997 Mikael Djurfeldt <mdj@kenneth>
4084 * regex-posix.c: If <regex.h> can't be found, try <rxposix.h> or
4085 <rx/rxposix.h>. (This is in order to accomodate for the GNU Rx
4088 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp, ramap_1,
4089 ramap_2o, scm_array_index_map_x, raeql_1, scm_array_equal_p),
4090 unif.c (scm_vector_set_length_x, scm_uniform_vector_length,
4091 scm_array_p, scm_array_rank, scm_array_dimensions,
4092 scm_enclose_array, scm_array_in_bounds_p, scm_uniform_vector_ref,
4093 scm_cvref, scm_array_set_x, scm_array_contents, scm_array_to_list,
4094 scm_array_prototype): Added case scm_tc7_wvect.
4096 Sat Aug 23 18:45:44 1997 Gary Houston <ghouston@actrix.gen.nz>
4098 * errno.h: prototype for scm_strerror.
4099 * error.c (scm_strerror): new procedure.
4101 Mon Aug 18 14:58:22 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4103 * list.c (scm_list_append_x): Allow non-pair as last argument.
4104 This is consistent with the R4RS append and is probably the
4105 correct behaviour as specified by R2RS. (Thanks to Radey Shouman)
4107 Sat Aug 16 18:42:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4109 * stime.h: prototype for scm_times.
4110 * stime.c (scm_times): new procedure.
4111 * ioext.c (scm_fseek): if the first argument is a file descriptor
4113 (scm_ftell): if the first argument is a file descriptor call lseek
4115 * filesys.h: prototypes for scm_open_fdes, scm_fsync.
4116 * filesys.c (scm_chmod): if the first argument is a file descriptor,
4118 (scm_chown): if the first argument is a port or file descriptor,
4120 (scm_truncate_file): new procedure.

4122 (scm_fsync): new procedure.
4123 (scm_open_fdes): new procedure.
4124 (scm_open): use scm_open_fdes. If mode isn't specified, 666 will
4126 (scm_fcntl): the first argument can now be a file descriptor. The
4127 third argument is now optional.
4129 * posix.c (scm_execl, scm_execlp): make the filename argument
4130 compulsory, since omitting it causes SEGV.
4131 (scm_sync): return unspecified instead of #f.
4132 (scm_execle): new procedure.
4133 (environ_list_to_c): new procedure.
4134 (scm_environ): use environ_list_to_c. disable interrupts.
4135 (scm_convert_exec_args): take pos and subr arguments and
4136 improve error checking.
4138 1997-08-14 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4140 * stacks.c (scm_make_stack), coop-threads.c, mit-pthreads.c
4141 (scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
4142 argument to SCM_ASSERT. Furthermore, the name of the function
4143 should be passed as first argument when signalling
4144 SCM_WNA. (Thanks to Thomas Morgan)
4146 * gsubr.c (scm_gsubr_apply): From Radey Shouman
4147 <shouman@zianet.com>: "The switch in scm_gsubr_apply that
4148 dispatches on the number of actual args has a default case
4149 reporting an internal error. This is a vestige from a version
4150 that mallocated a SCM vector to hold the arguments. In the
4151 current version this check is too late: if it ever happens we will
4152 have already overstepped the bounds of the array.
4154 Also, the patch [...] adds a check for too many actual arguments."
4156 mdj: Removed check for "internal programming error".
4158 Wed Aug 13 15:38:44 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4160 * gh_io.c (gh_write): New function.
4162 * gh_eval.c (catch_with_saved_stack): Removed. Replaced by:
4163 throw.c (scm_internal_stack_catch): New sibling to the other catch
4164 functions. Code moved from gh_eval.c.
4165 throw.h: Added header.
4166 gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
4167 scm_internal_stack_catch.

4171 * ioext.h: fix up prototypes.
4172 * ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
4173 Scheme name is now dup->fdes.
4174 (scm_dup_to_fdes): make the second argument optional and
4175 fold in the functionality of scm_primitive_dup.
4176 (scm_primitive_dup): deleted.
4178 Mon Jul 28 05:24:42 1997 Gary Houston <ghouston@actrix.gen.nz>
4180 * fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
4181 * fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
4182 ultrix are defined. Use setvbuf instead of setbuf.
4183 (scm_setvbuf): new procedure.
4184 (scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
4185 (scm_setfileno): moved from ioext.c.

4197 state as nested data while they are printed.
4198 (print_state_fluid, print_state_fluid_num): New variables.
4199 (scm_init_print): Initialize them.
4200 (scm_iprin): If print_state_fluid carries a print_state, use that
4201 instead of creating a new one.
4202 (scm_printer_apply, apply_stub, struct apply_data): New
4203 definitions to help with calling printer functions written in
4205 * print.h (scm_printer_apply): New prototype.

4218 * fluids.c (scm_fluid_ref, scm_fluid_set_x): Fixed use of
4219 SCM_ASSERT: arg comes before pos.
4221 Fri Jul 25 17:00:38 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
4223 * eval.c (scm_apply): Handle the case when a tc7_sybr_2 is applied
4224 to a list of length zero correctly.
4226 Wed Jul 23 16:17:46 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>

4242 * ioext.h: removed scm_duplicate_port prototype.
4244 * ioext.c (scm_primitive_dup2): return the new file descriptor
4245 instead of SCM_UNSPECIFIED, since similarity to scm_primitive_dup
4247 (scm_fdopen): bug fix: don't try to make port unbuffered until its
4248 stream has been set.
4249 (scm_duplicate_port): deleted, there's now an implementation in
4251 (scm_primitive_dup2): do nothing if newfd == oldfd.
4253 Sun Jul 20 03:55:49 1997 Gary Houston <ghouston@actrix.gen.nz>
4255 * filesys.c (scm_close): oops, don't call SCM_INUM twice on the

4261 * fluids.c (next_fluid_num): don't do
4262 SCM_THREAD_CRITICAL_SECTION_START/END unless USE_THREADS is defined.
4264 * ports.h: prototypes too.
4265 * ports.c (scm_mode_bits, scm_port_mode): moved from fports.c.
4267 * fports.h: prototype too.
4268 * fports.c (scm_evict_ports): moved from ioext.c.
4270 Sat Jul 19 04:56:52 1997 Gary Houston <ghouston@actrix.gen.nz>
4272 * ports.c (scm_close_port): return a boolean instead of unspecified.
4273 throw an error if an error other than EBADF occurs.
4275 * filesys.h: scm_close prototype.
4276 * filesys.c (scm_close): new procedure, can close file descriptors
4277 and ports (scsh compatible).
4279 * ports.c (scm_flush_all_ports): SCM_PROC incorrectly allowed an
4282 Fri Jul 18 11:19:53 1997 Marius Vollmer <mvo@zagadka.ping.de>
4284 * fluids.c, fluid.h: New files.

4295 (scm_make_root): Call scm_copy_fluids to make fluid bindings
4296 unique for the new root when it has a parent.
4298 * smob.h: Include "libguile/print.h" to make scm_print_state
4301 * dynl.c (free_dynl_obj): New function to free the dynamic object
4302 data. (dynl_smob): Use it.
4303 * dynl.c (scm_dynamic_link): Moved allocating of the memory for
4304 the dynamic object data below the linking of the object to avoid
4305 memory leak when the linking code throws an error. Now the code
4306 leaks a whole dynamically linked library when must_malloc throws,
4307 but that should be much less likely.
4309 Fri Jul 11 00:19:47 1997 Jim Blandy <jimb@floss.red-bean.com>
4311 Changes to compile under gnu-win32, from Marcus Daniels:

4327 (scm_setpwent): For setpwent.
4328 (scm_setegid): For setegid.
4329 * net_db.c (scm_inet_netof): Don't include unless support

4349 think this is left over from the (eq? '() #f) days.
4351 * read.c (recsexpr): Give this a dummy definition if
4352 DEBUG_EXTENSIONS isn't #defined.
4354 Fri Jul 4 23:42:17 1997 Marius Vollmer <mvo@zagadka.ping.de>
4356 * coop-threads.c (scm_wait_condition_variable): Lock mutex again

4366 * Makefile.am (libguile_la_LIBADD): Remove @ALLOCA@, since
4367 alloca.lo will be included in @LIBLOBJS@. Something better than
4368 this should be possible.
4369 * Makefile.in: Regenerated.
4371 Sat Jun 28 03:40:15 1997 Gary Houston <ghouston@actrix.gen.nz>
4373 * simpos.h: prototype for scm_primitive_exit.

4379 * regex-posix.c (scm_make_regexp): Make `flags' a variable-length
4380 argument and logior its components together, so the user doesn't
4381 have to do this explicitly. Also, if regexp/basic is supplied, then
4382 turn off REG_EXTENDED.
4383 (scm_init_regex_posix): New regexp/basic symbol.
4384 (REG_BASIC): #define this if it is not already present.

4400 * Makefile.in: Regenerated.
4402 * regex-posix.c (scm_init_regex_posix): Delete the regexp/nosub
4403 flag; I don't think we support it.
4404 (scm_make_regexp): Make sure the user doesn't pass the
4407 * regex-posix.c (scm_make_regexp, scm_regexp_exec): Add optional
4409 (scm_init_regex_posix): Define constants for the REG_mumble flags;

4427 * root.c: Establish a reliable catch-all handler for the new root.
4428 After all the Scheme handler function might signal an error too,
4429 and we don't want to lose that.
4430 (cwdr_inner_body): Renamed from cwdr_body.
4431 (cwdr_outer_body): New function, to establish the user's handler,
4432 and pass control to cwdr_inner_body.
4433 (cwdr): Establish the reliable catch-all handler here, and pass
4434 control to cwdr_outer_body.
4435 (struct cwdr_body_data): New field, handler, to allow cwdr to pass
4436 the user's handler through to cwdr_outer_body.

4443 across this. Only works on GCC. Otherwise, we hope for the best.
4444 (SCM_DEFER_INTS, SCM_ALLOW_INTS): Use FENCE appropriately. I have
4445 the feeling that real thread systems will not need this...
4447 Sun Jun 22 15:46:35 1997 Jim Blandy <jimb@floss.red-bean.com>
4449 Try to detect when people are using one version of libguile and a

4461 primitive definitions under their Scheme names.
4463 * Makefile.am (libguile_la_LDFLAGS): Update library version to
4464 1:2. Helps avoid confusion between installed and uninstalled libs.
4466 * scmconfig.h.in: Regenerated. (Needed after June 3 change to
4469 * gdb_interface.h (GDB_INTERFACE): Remove semicolon and trailing
4470 backslash from definition; this should be used like: GDB_INTERFACE;
4472 Sun Jun 22 04:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4474 * ioext.c (scm_duplicate_port): bug fix: don't try to make the
4475 new port unbuffered until its stream has been set.
4477 Sat Jun 21 18:44:03 1997 Gary Houston <ghouston@actrix.gen.nz>
4479 * ports.h: new prototype.
4480 * ports.c (scm_flush_all_ports): new procedure, scsh compatible.
4482 Sat Jun 21 00:25:03 1997 Jim Blandy <jimb@floss.red-bean.com>
4484 Make things compile neatly under Sun's C compiler.
4485 * dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
4486 * extchrs.c (xmbtowc): Make the second arg a normal char, not
4487 unsigned, because that's what the ANSI function takes.
4488 * extchrs.h (xmbtowc): Corresponding change to prototype.
4489 * genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
4491 * mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
4492 argument plain char *.
4493 * strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
4495 * tag.c (scm_tag): Remove unreachable statement.
4496 * unif.c (scm_array_to_list): If we want to shift a 1 bit to the
4497 top of the word, it should be unsigned.
4499 * eval.c (scm_lookupcar1): Don't declare var2 unless USE_THREADS
4500 is defined, to avoid warnings; it's only used in the
4501 conflict-checking code. Which might go away anyway.
4502 (SCM_CEVAL): All goto's targeting the `dispatch' label are in
4503 conditionals; put the label definition in an #if too, to stifle
4506 * Makefile.am (EXTRA_DIST): Include ChangeLog-gh and
4507 ChangeLog-threads in the distribution.
4508 * Makefile.in: Regenerated.
4510 Fri Jun 20 10:03:41 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4512 * guile-snarf.in: Changed regexp to support CPPs that insert
4513 whitespace between lexical tokens (which munges the `%%%' snarf
4516 Tue Jun 17 13:49:56 1997 Tim Pierce <twpierce@bio-5.bsd.uchicago.edu>
4518 * load.c (scm_init_load_path): Append $(datadir)/guile to
4519 %load-path, so modules do not have to be installed in Guile's
4520 current version directory.
4522 Mon Jun 16 17:20:55 1997 Marius Vollmer <mvo@zagadka.ping.de>
4524 * dynl.c (scm_dynamic_call, scm_dynamic_args_call): Wrap dynamic
4525 function call in SCM_DEFER_INTS/SCM_ALLOW_INTS.
4526 (scm_dynamic_link, scm_dynamic_unlink, scm_dynamic_func): Always
4527 call the sysdep functions with deferred ints.
4528 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c (sysdep_dynl_link,
4529 sysdep_dynl_unlink, sysdep_dynl_func): Expect to be called with
4530 deferred interrupts and insert SCM_ALLOW_INTS before throwing an
4533 * dynl.c (scm_dynamic_unlink, scm_dynamic_call): Return
4536 Sat Jun 14 19:00:58 1997 Gary Houston <ghouston@actrix.gen.nz>
4538 * scmsigs.c (sys_deliver_signals): add a comment about a probable bug.
4540 Wed Jun 11 00:33:00 1997 Jim Blandy <jimb@floss.red-bean.com>
4542 * Makefile.in: Regenerated after xtra_PLUGIN_guile_libs change in
4545 Sun Jun 8 14:37:26 1997 Marius Vollmer <mvo@zagadka.ping.de>
4547 * eval.c (scm_lookupcar1): New procedure to cope with a race
4548 condition during lookup (when using threads).
4549 (scm_lookupcar): Implement in terms of scm_lookupcar1.
4550 (SCM_CEVAL): Use scm_lookupcar1 instead of scm_lookupcar in one
4553 Fri Jun 6 19:05:07 1997 Jim Blandy <jimb@totoro.cyclic.com>
4555 * regex-posix.c (scm_regexp_exec): Use the `start' argument if
4556 supplied. (Change from Tim Pierce.)
4558 Thu Jun 5 16:38:19 1997 Marius Vollmer <mvo@zagadka.ping.de>
4560 * struct.c (init_struct): Forget to mention this in the "Wed Jun 4
4561 23:47:01 1997" changelog: Slots are now initialized with `#f' by
4562 default and not `()'. `#f' is the canonical non-value in Scheme,
4565 Wed Jun 4 23:47:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4567 * struct.c (struct_printer): New variable that holds a handle on
4568 the Scheme variable *struct-printer*. This variable can be set by
4569 Scheme code to override the printing of structures.
4570 (scm_print_struct): If struct_printer is set, call it. If it is
4571 not set, or returns #f, print the structure in the old fashion.
4572 Include "eval.h" for scm_apply.
4574 Tue Jun 3 23:01:39 1997 Marius Vollmer <mvo@zagadka.ping.de>
4576 * struct.c (scm_struct_ref, scm_struct_set_x): Use
4577 scm_struct_i_n_words to get the number of fields, not
4578 -scm_struct_n_extra_words.
4580 On the route to fancier struct printing:
4581 * struct.c (scm_print_struct): New function to print a structure.
4582 Include "genio.h" to support it. This function doesn't do
4583 anything interesting right now, but I think it should be here
4585 * struct.h: Include "print.h" and add prototype for
4587 * print.c (scm_iprin1): Call scm_print_struct instead of trying to
4588 print structures ourself.
4590 Sun Jun 1 07:58:41 1997 Gary Houston <ghouston@actrix.gen.nz>
4592 * scmsigs.c (sys_deliver_signals): bug fix: reset got_signal[i]
4593 before applying the handler in case it doesn't return.
4595 Sat May 31 18:57:51 1997 Gary Houston <ghouston@actrix.gen.nz>
4597 * scmsigs.h, async.h: updated.
4599 * _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
4602 * posix.c (scm_uname): interpret only negative values as an error.
4603 Solaris normally returns a positive value.
4605 * script.c (scm_compile_shell_switches): if we are not going into
4606 an interactive repl, set scm_mask_ints to zero so that asyncs can
4609 * simpos.c (scm_system): don't ignore/unignore signals around
4612 * posix.c (scm_open_pipe): don't ignore/unignore signals around
4615 * init.c (scm_boot_guile_1): don't call scm_init_signals, it's
4616 done in boot-9.scm instead.
4618 * scmsigs.c, async.c: Major rewriting of signal handling code.
4619 (scm_sigaction): new procedure.
4620 (scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
4622 (scm_raise): return unspecified, throw error on failure.
4624 Thu May 29 02:47:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4626 * regex-posix.c (scm_init_regex_posix): Register the "regex"
4627 feature, to help boot-9.scm decide whether to import the regex
4630 Thu May 29 02:19:40 1997 Jim Blandy <jimb@floss.cyclic.com>
4632 * eval.c: Include scmconfig.h at the beginning of the file so that
4633 HAVE_ALLOCA_H may properly be defined. Thanks to Bill Janssen for
4636 * regex-posix.c: #include "_scm.h" before conditionally #including
4637 <regex.h>; the former defines HAVE_REGCOMP.
4639 * regex-posix.c: #include <regex.h> conditionally, so the file is
4640 CPP'able (for dependency scanning) even on systems that don't have
4643 Tue May 27 23:48:38 1997 Jim Blandy <jimb@floss.cyclic.com>
4645 Add new R4RS-compliant syntax for keywords.
4646 * read.c (scm_lreadr): Recognize `#:' as a prefix for keywords,
4647 regardless of the setting of the `keywords' read option.
4648 * kw.c (prin_kw): Print keywords using the `#:' syntax, so they
4649 can be re-read no matter what the setting of the `keywords' read
4652 Tue May 27 22:47:31 1997 Tim Pierce <twp@twp.tezcat.com>
4654 Add support for POSIX regular expressions.
4656 * regex-posix.c, regex-posix.h: New files. (Some code
4657 is taken liberally from rx/rgx.c in the old Guile dist.)
4659 * init.c: Include regex-posix.h.
4660 (scm_boot_guile_1): Call scm_init_regex_posix.
4662 * Makefile.am (EXTRA_libguile_la_SOURCES, modinclude_HEADERS):
4663 Add regex-posix.[ch] sources.
4664 * Makefile.in: Regenerated.
4666 * scmconfig.h.in: Add HAVE_REGCOMP macro. (automake is supposed
4667 to do this automatically? It didn't for me, bleh.)
4669 Mon May 26 18:51:29 1997 Jim Blandy <jimb@floss.cyclic.com>
4671 * fports.c (print_pipe_port): New function.
4672 (scm_fptob): Use print_pipe_port instead of scm_prinport; the
4673 latter doesn't even take the right arguments.
4675 * Makefile.am: Increment shared lib revision number. I think
4676 sometimes the uninstalled Guile finds the installed shared lib;
4677 Gord says doing this might help. As things turned out, I can't
4678 say whether it does.
4679 * Makefile.in: Regenerated.
4681 * gh_init.c (gh_enter): Cast c_main_prog to a void * before
4682 passing it as the closure argument to scm_boot_guile. (Bill
4685 * ports.c (print_void_port, putc_void_port, puts_void_port,
4686 write_void_port, flush_void_port, getc_void_port, close_void_port,
4687 noop0): Use ANSI prototypes instead of K&R declarations, so the
4688 initialization of void_port_ptob gets aggressively type-checked.
4689 Fix arguments of print_void_port and write_void_port. (Bill

4723 Mon May 26 12:37:30 1997 Jim Blandy <jimb@floss.cyclic.com>
4725 * script.c (scm_find_executable): Use prototype-style definition
4726 here; apparently it's not quite right to have const in a prototype
4727 and then use a K&R declaration. I wonder if stuff like this will
4728 go away if we compile with -Wrequire-prototypes, or whatever that
4729 is... (Bernard URBAN)
4731 * scmhob.h: New text from Bernard URBAN.
4733 Sat May 17 17:14:36 1997 Jim Blandy <jimb@floss.cyclic.com>
4735 * script.c: Don't #define const on hpux. Configure takes care of
4736 this. (Thanks to Larry Schwimmer.)
4738 * script.c: Use the HAVE_UNISTD_H symbol provided by autoconf to
4739 decide whether to #include <unistd.h>, instead of listing a bunch
4740 of systems. Don't #include stdio twice. Removed dyked-out
4741 definition of scm_find_impl_file.
4743 Fri May 16 03:06:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4745 * Makefile.am (libguile_la_LDFLAGS): Update libguile's shared
4746 library version info to 1:0.
4747 * Makefile.in: Regenerated.
4749 * backtrace.c, backtrace.h, debug.c, debug.h, eq.c,

4753 script.h, snarf.h, srcprop.c, srcprop.h, stacks.c, stacks.h,
4754 throw.c: Update copyright years; these files have been worked on
4755 significantly in 1997, but only had copyright years for 1996.
4756 Also, change name of copyright holder on some from Mikael
4757 Djurfeldt to Free Software Foundation; he has signed papers
4758 assigning the changes to the FSF.
4760 * script.c (scm_shell_usage): Pass FATAL to exit. There's no
4761 reason not to give the user the option.
4763 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
4764 Return #f on end-of-file when scanning table (i.e. when called
4765 with no arguments). Try to catch errors, when we can.
4766 * posix.c (scm_getgrgid, scm_getpwuid): Same.
4768 * script.h (scm_shell_usage, scm_compile_shell_switches): New
4769 external declarations. These are useful.
4771 Thu May 15 05:21:36 1997 Gary Houston <ghouston@actrix.gen.nz>
4773 * posix.c: don't include <sys/select.h> or define macros for
4774 select, since they were not used in this file.
4776 * filesys.c (scm_select): make the fifth parameter microseconds,
4777 not milliseconds. let the fourth parameter be either a real value
4778 or an integer or #f. The first, second and third arguments can
4779 now be vectors: the type of the corresponding return set will be
4781 (set_element, get_element): new static procedures.
4783 Wed May 14 12:18:12 1997 Jim Blandy <jimb@floss.cyclic.com>
4785 * strports.c (scm_eval_string): New function.
4786 (scm_eval_0str): Trivially re-implemented in terms of
4788 * strports.h (scm_eval_string): New extern decl.
4790 * net_db.c (h_errno): Add extern decl for this.
4792 * fports.c (local_pclose): New function.
4793 (scm_pipob): Use it in the initializer here.
4796 * net_db.c (scm_gethost, scm_getproto, scm_getnet, scm_getserv):
4797 Use a meaningful error message when signalling an error. For
4798 this, scm_gethost must check h_errno rather than errno.
4800 Tue May 13 16:40:06 1997 Jim Blandy <jimb@floss.cyclic.com>
4802 * Makefile.in: Regenerated, using automake-1.1p.
4804 Tue May 13 04:34:52 1997 Gary Houston <ghouston@actrix.gen.nz>
4806 * socket.c (scm_addr_vector): use SCM_UNDEFINED in scm_listify,
4807 not SCM_UNSPECIFIED.
4809 * script.c (scm_compile_shell_switches): don't append (quit) if
4811 (scm_shell): call scm_exit_status and exit on the result of the
4814 Mon May 12 17:23:58 1997 Jim Blandy <jimb@floss.cyclic.com>
4816 Ensure that shared substrings are handled properly when passed to
4817 a system call or other foreign function. Many thanks to Tim
4819 * symbols.h (SCM_COERCE_SUBSTR): new macro.
4820 * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir,
4821 scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink,
4822 scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime,

4833 scm_strftime), vports.c (scm_make_soft_port): use
4834 SCM_COERCE_SUBSTR to make sure shared substrings are
4837 Mon May 12 15:33:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
4839 * error.c (scm_error): Add newline to error message.
4841 * init.c (scm_init_standard_ports): Doc fix.
4843 Thu May 8 14:38:01 1997 Marius Vollmer <mvo@zagadka.ping.de>
4845 * dynl-shl.c: Completely replaced with new code from Bernard
4848 * script.c (scm_ice_9_already_loaded): New variable.
4849 (scm_compile_shell_switches): Use it.
4851 Mon May 5 20:35:08 1997 Gary Houston <ghouston@actrix.gen.nz>
4853 * filesys.c (scm_input_waiting_p): add missing third argument to

4857 calling gmtime in case they share a buffer.
4858 (scm_localtime, scm_mktime): throw an error if neither HAVE_TM_ZONE
4861 Fri May 2 19:07:11 1997 Gary Houston <ghouston@actrix.gen.nz>
4863 * eq.c (scm_equal_p): use SCM_TYP7SD (y) not SCM_TYP7SD (x).
4865 Thu May 1 17:01:45 1997 Jim Blandy <jimb@floss.cyclic.com>
4867 * Makefile.am (check-local): New target, which causes 'make check'
4868 to run gh_test_c and gh_test_repl, with some trivial input.
4869 * Makefile.in: Rgnrtd.
4871 Tue Apr 29 19:00:40 1997 Marius Vollmer <mvo@zagadka.ping.de>
4873 * dynl.c (print_dynl_obj): Indicate whether the dynamic object has
4876 Mon Apr 28 06:10:14 1997 Gary Houston <ghouston@actrix.gen.nz>
4878 * async.c (scm_sys_tick_async_thunk): commented out. I'm not
4879 sure how this was supposed to work.
4880 (scm_async_click): don't send SCM_TICK_SIGNAL.
4881 (scm_init_async): don't initialize %tick-thunk.
4883 * the following change doesn't affect the Scheme interface:
4884 gc-thunk is called at the end of garbage collection. however it's
4885 no longer implemented by pretending it's a signal.
4887 * gc.c (scm_gc_end): don't call scm_take_signal. instead mark the
4888 system async corresponding to scm_gc_thunk.
4889 * async.h: declare scm_gc_async.
4890 * async.c (scm_sys_gc_async_thunk): apply the thunk named by
4891 gc-thunk directly, instead of going through a signal handler.
4892 (scm_gc_async): new variable, points to the GC system-async.
4893 (scm_init_async): save the GC async as scm_gc_async instead
4894 of using system_signal_asyncs.
4895 (scm_gc_vcell): new variable, stores the gc-thunk vcell.
4897 Mon Apr 28 19:14:44 1997 Jim Blandy <jimb@floss.cyclic.com>

4900 Don't screw up if we're interrupted.
4901 * Makefile.in: Regeneradet.
4903 Sun Apr 27 17:57:15 1997 Jim Blandy <jimb@floss.cyclic.com>
4905 * aclocal.m4: Removed; unnecessary, given changes of Apr 24.
4907 * Makefile.am (modincludedir): Use "ice-9" instead of "@module@";
4908 we're not using AM_INIT_GUILE_MODULE any more.
4909 * Makefile.in: Reneregated.
4911 Thu Apr 24 00:41:08 1997 Jim Blandy <jimb@floss.cyclic.com>
4913 Functions for finding variable bindings, grace à Tim Pierce.

4917 Get 'make dist' to work again.
4918 * Makefile.am (EXTRA_DIST): Remove PLUGIN files.
4919 * Makefile.in: Regenerated, like a surry without a fringe on top.
4921 Changes for reduced Guile distribution: one configure script,
4923 * configure.in, configure: Removed.
4924 * acconfig.h, acinclude.m4: Moved to parent directory, where the
4925 real configure script lives.
4926 * Makefile.in, scmconfig.h.in: Regenerated.
4928 * init.c: #include "script.h", to get prototype for script.c's
4931 Wed Apr 23 21:25:39 1997 Jim Blandy <jimb@floss.cyclic.com>
4933 * gh_data.c (gh_scm2newstr, gh_symbol2newstr): Use
4934 scm_must_malloc, not raw malloc.
4936 * script.c (scm_compile_shell_switches): Dyke out debugging output
4939 Mon Apr 21 05:00:32 1997 Gary Houston <ghouston@actrix.gen.nz>
4941 * eq.c (scm_equal_p): use "SCM_TYP7SD", not "SCM (TYP7SD".
4943 * stime.c: include both <sys/times.h> and <sys/timeb.h> if the
4944 system has them. Hope this is safe. Previously
4945 sys/timeb.h was included if HAVE_FTIME was defined or if
4946 HAVE_SYS_TIMEB_H was defined but HAVE_SYS_TIMES_H was not,
4947 but IRIX iris 5.3 apparently has ftime but not sys/timeb.h.
4949 * ioext.c (scm_setfileno): add missing third argument to
4950 scm_misc_error call.
4952 Sun Apr 20 15:09:31 1997 Jim Blandy <jimb@totoro.cyclic.com>
4954 * eq.c (scm_equal_p): Correctly compare strings of different
4955 varieties. (Thanks to Tim Pierce.)
4957 Sat Apr 19 03:59:02 1997 Jim Blandy <jimb@floss.cyclic.com>
4959 * read.c (skip_scsh_block_comment): SCSH says the !# that ends a
4960 #! block comment must occur on a line all by itself.
4962 Move most of the guts of shell command processing into libguile,
4963 so guile.c can be very small (and eventuallly auto-generated. (I
4964 mean, generated mechanically, not self-generated. Hmm.))
4965 * guile.c, script.c, script.h: New source files.
4966 * init.c (scm_boot_guile_1): Call scm_init_script.
4967 * libguile.h: #include "script.h".
4968 * Makefile.am (bin_PROGRAMS, guile_SOURCES, guile_LDADD): New
4969 targets, for new executable.
4970 (libguile_la_SOURCES): Mention script.c.
4971 (modinclude_HEADERS): Add script.h.
4972 * configure.in: Always check for -lm, -lsocket, -lnsl, whether or
4973 not dynamic linking is enabled. This is because we're generating
4974 executables now. Move CY_AC_WITH_THREADS call after those, so the
4975 values of cy_cv_threads_libs captures the libs chosen above.
4976 * Makefile.in, configure, aclocal.m4: Regenerated.
4978 * Makefile.am (EXTRA_DIST): Don't distribute gscm.c or gscm.h.
4979 We don't maintain this interface any more, and it just confuses
4982 * alloca.c: #include <scmconfig.h>, not <config.h>.
4983 * Makefile.am (EXTRA_libguile_la_SOURCES): Mention alloca.c, so
4984 it'll get included in disties.
4986 Thu Apr 17 17:45:10 1997 Jim Blandy <jimb@totoro.cyclic.com>
4988 * gscm.c, gscm.h: These aren't supported any more, and shouldn't
4989 be distributed, because they confuse people.
4990 * Makefile.am (EXTRA_DIST): Remove gscm.c, gscm.h.
4992 Sat Apr 19 11:56:18 1997 Tim Pierce <twp@twp.tezcat.com>
4994 * configure.in: check for presence of gethostent (not present on
4995 OpenBSD by default).
4996 * net_db.c (scm_gethost): Check HAVE_GETHOSTENT.
4997 * configure, scmconfig.h.in: Regenerated.
4999 Wed Apr 16 17:52:38 1997 Jim Blandy <jimb@floss.cyclic.com>
5001 * backtrace.c (scm_backtrace): Split message string across
5002 newlines properly. GCC is more tolerant of this than other
5005 Mon Apr 14 20:20:14 1997 Jim Blandy <jimb@floss.cyclic.com>
5007 Merge threads directory into libguile.
5008 * coop-defs.h, coop-threads.c, coop-threads.h, coop.c, threads.c,
5009 threads.h: New source files.
5010 * Makefile.am (EXTRA_libguile_la_SOURCES): Add threads.c.
5011 (noinst_HEADERS): Add coop-threads.c, coop-threads.h, coop.c
5013 (modinclude_HEADERS): Add threads.h, coop-defs.h.
5014 (EXTRA_DIST): Add fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5015 coop-threads.c.cygnus, coop-threads.h.cygnus.
5016 * configure.in: If we're using threads, include threads.o in
5018 * _scm.h, libguile.h: threads.h lives in this directory now.
5019 * fsu-pthreads.h, mit-pthreads.c, mit-pthreads.h,
5020 coop-threads.c.cygnus, coop-threads.h.cygnus: New files, not
5021 currently used, but brought along for information's sake.
5022 * ChangeLog-threads: log from old 'threads' directory.
5023 * Makefile.in, configure: Rebuilt.
5025 Mon Apr 14 20:15:29 1997 Jim Blandy <jimb@totoro.cyclic.com>
5027 * stime.c (scm_mktime): #ifndef HAVE_TM_ZONE, Use lt.tm_zone, not
5030 Mon Apr 14 01:32:57 1997 Jim Blandy <jimb@floss.cyclic.com>
5032 * gh_init.c (gh_standard_handler): Return SCM_BOOL_F, not garbage.
5034 Merge GH interface library into libguile.
5035 * gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
5036 gh_list.c, gh_predicates.c, gh_test_c.c, gh_test_repl.c: New files.
5037 * Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
5038 gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
5040 (EXTRA_libguile_la_SOURCES): ... here.
5041 (pkginclude_HEADERS): Add variable, to get gh.h installed.
5042 (THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
5043 gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
5044 New variables, describing how to build the gh test programs.
5045 * configure.in: Check for -lm, -lsocket, -lnsl; we need this to
5046 build the test programs, and we probably should have been linking
5047 libguile.la against them all along, to support AIX shared libs.
5048 Add cflags for threads to CFLAGS; add libs for threads to new
5049 variable THREAD_LIBS, used in Makefile.am.
5050 * ChangeLog-gh: log from old `gh' subdirectory.
5051 * Makefile.in, configure, scmconfig.h.in: Rebuilt.
5053 Sun Apr 13 23:03:55 1997 Jim Blandy <jimb@floss.cyclic.com>
5055 * acconfig.h: Undo change of Apr 9; including the definition of
5056 PACKAGE in the guile headers conflicts with applications' own
5058 * scmconfig.h.in: Regenerated.
5060 Fri Apr 11 14:12:13 1997 Jim Blandy <jimb@floss.cyclic.com>

5063 (scm_init_filesys): New symbols for use with fcntl.
5064 * filesys.h: Added prototype.
5066 * eval.c (SCM_APPLY): Set debug apply frame argument list correctly
5067 when PROC is receiving no arguments.
5069 Fri Apr 11 19:39:32 1997 Jim Blandy <jimb@totoro.cyclic.com>
5071 * filesys.c (S_ISSOCK): Define this if it's missing, but we do
5072 have S_IFSOCK. This is the case under Ultrix.
5074 * posix.c (scm_status_exit_val, scm_status_exit_val,
5075 scm_status_term_sig, scm_status_stop_sig): Modified to work with
5076 Ultrix versions of WIFSTOPPED, etc., which assume that their
5077 arguments are lvalues (hmm).
5079 Thu Apr 10 15:10:07 1997 Jim Blandy <jimb@floss.cyclic.com>
5081 * eval.c: Doc fixes.
5083 * throw.c: Doc fixes; rearranged.
5085 * putenv.c: #include "libguile/scmconfig.h", not <config.h>.
5087 Wed Apr 9 18:01:20 1997 Jim Blandy <jimb@floss.cyclic.com>
5089 * acconfig.h: Added entry for PACKAGE.
5090 * scmconfig.h.in: Regenerated.
5092 Changes to work with automake-1.1n, which has better libtool support.
5093 * Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
5094 Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
5096 (libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
5098 * Makefile.in: Rebuild.
5100 Wed Apr 9 09:08:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5102 * stime.c (scm_mktime): take an optional zone argument.
5103 (scm_localtime): check putenv return value.
5104 (scm_strftime, scm_strptime): moved from posix.c. move #include
5106 stime.h, posix.h: update prototypes.
5107 (bdtime2c, setzone, restorezone): new static procedures.
5108 (scm_mktime, scm_strftime): use them.
5109 (scm_strftime): don't call mktime before strftime. Use
5110 filltime for return value.
5111 (filltime): convert NULL zname to #f.
5112 (scm_strptime): return a count of characters consumed, not
5113 the remaining string.
5115 Sun Apr 6 05:44:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5117 * stime.c (scm_localtime): check HAVE_TM_ZONE and HAVE_TZNAME.
5118 (scm_mktime): likewise.
5120 Uncomment localtime and mktime.
5122 * configure.in: add AC_STRUCT_TIMEZONE.
5124 Sat Apr 5 23:56:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5126 * stime.c (scm_init_stime): don't define ticks/sec.
5127 (scm_gettimeofday): renamed from scm_time_plus_ticks (avoids multiple
5128 return value problem and is still portable.)
5130 Sat Apr 5 17:59:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5132 * cpp_err_symbols.in: Renamed from cpp_err_symbols, to avoid
5133 make's implicit cpp_err_symbols: cpp_err_symbols.c rule.
5134 * cpp_sig_symbols.in: Renamed from cpp_sig_symbols.
5135 * Makefile.am (check_errnos, check_signals, cpp_sig_symbols.c,
5136 cpp_err_symbols.c): Corresponding changes.
5137 * Makefile.in: Regenerated.
5139 Sat Apr 5 02:39:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5141 * posix.c (scm_putenv): don't check HAVE_PUTENV.
5142 * Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
5143 * configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
5144 * putenv.c: new file, from sh-utils 1.12.
5146 * posix.c (scm_environ): use malloc in place of scm_must_malloc
5147 since allocation isn't for Scheme objects.
5148 (scm_putenv): copy strings before placing in the environment.
5150 * stime.c (scm_current_time): throw an error if time returns -1,
5151 instead of returning #f.
5152 (scm_get_internal_real_time, scm_get_internal_real_time): use
5153 scm_long2num for return value instead of SCM_MAKINUM.
5155 * stime.h: prototypes updated.
5157 * stime.c (scm_time_in_msec): apparently unused, deleted.
5159 Fri Apr 4 08:53:41 1997 Gary Houston <ghouston@actrix.gen.nz>
5161 * configure.in: check for gettimeofday.
5163 * stime.c (scm_time_plus_ticks): new procedure, an scsh interface
5164 which may be more usefully portable than a gettimeofday interface.
5166 Wed Apr 2 17:11:39 1997 Jim Blandy <jimb@totoro.cyclic.com>
5168 * Makefile.am (EXTRA_DIST): It's cpp_err_symbols, not
5170 * Makefile.in: Regenerated.
5172 Mon Mar 31 03:22:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5174 * stime.c (filltime): recovered static procedure.
5175 (scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
5178 * posix.h: add prototype for scm_close_pipe, remove prototypes for
5179 scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
5181 * posix.c (scm_mknod): split the mode argument into type and perms
5182 arguments, like the extra fields returned by stat.
5184 * fports.c (scm_pipob): set the close, free and print procedures.
5185 (scm_close_pipe): new procedure.
5187 * posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
5188 define them in boot-9.scm
5190 Wed Mar 26 04:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5192 * ioext.c (scm_setfileno): throw a runtime error if SET_FILE_FD_FIELD
5193 wan't defined. Don't include fd.h.
5195 * Previously fd.h was regenerated whenever configure was run,
5196 forcing a couple of files to be recompiled.
5198 * fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
5199 * configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
5200 Check for _fileno as well as _file.
5202 * ioext.c: don't fd.h.
5203 * acconfig.h: remove duplicate HAVE_FD_SETTER and change the
5206 * Change the stratigy for getting information about errno
5207 (and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
5208 generating lists of symbols during the build process, which will
5209 not always work, include comprehensive lists in the distribution.
5210 To help keep the lists up to date, the "check_signals" and
5211 "check_errnos" make targets can be used.
5213 * configure.in: don't check for a command to extract errno codes.
5214 * Makefile.am: update file lists, remove errnos.list and errnos.c
5215 targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
5216 check_errnos targets.
5217 (CLEANFILES): remove errnos.c and errnos.list, add
5218 cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
5219 cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
5220 * errnos.default: deleted.
5221 * cpp_signal.c: new file.
5222 * cpp_errno.c: renamed from errnos_get.c.
5223 * cpp_err_symbols, cpp_sig_symbols: new files.
5224 * cpp_cnvt.awk: renamed from errnos_cnvt_awk.
5225 * error.c (scm_init_error): #include cpp_err_symbols instead of
5227 * posix.c (scm_init_posix): don't intern signal symbols. #include
5230 Tue Mar 25 04:51:10 1997 Gary Houston <ghouston@actrix.gen.nz>
5232 * strop.c (scm_i_index): allow the lower bound to be equal to the
5233 length of the string, so a null string doesn't always give an error.
5235 * posix.h: new prototypes.
5236 * posix.c (scm_status_exit_val, scm_status_term_sig,
5237 scm_status_stop_sig): new functions, as in scsh. They break down
5238 process status values as returned by waitpid.
5240 Sat Mar 22 18:16:29 1997 Gary Houston <ghouston@actrix.gen.nz>
5242 * net_db.c (scm_gethost): don't check HAVE_GETHOSTENT, since
5243 configure doesn't know about it.
5245 Fri Mar 21 23:49:28 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5247 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.
5249 * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL
5250 which defines C variables with global linkage.
5252 Mon Mar 17 05:57:11 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5254 * snarf.h (SCM_PROC1): Bugfix: Use (void) rather than (...) for
5257 Sun Mar 16 11:43:49 1997 Mikael Djurfeldt <mdj@floss.cyclic.com>
5259 * eval.c (safe_setjmp): Temporarily use old setjmp until someone
5260 has time to check why this doesn't work well with continuations.
5262 Sun Mar 16 05:09:55 1997 Jim Blandy <jimb@totoro.cyclic.com>
5264 * Fix shell syntax error; some shells won't tolerate
5265 multiple "fi" statements on a single line. (Thanks to Fred Fish.)
5267 Sat Mar 15 01:11:40 1997 Gary Houston <ghouston@actrix.gen.nz>
5269 * posix.c (scm_uname): throw an error if uname fails instead
5272 * error.h (scm_errno, scm_perror): obsolete prototypes removed.
5274 * error.c (err_head, scm_errno, scm_perror): obsolete procedures
5277 * async.c (scm_ints_disabled): definition moved from error.c.
5279 Sat Mar 15 00:06:08 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5281 * acconfig.h: Removed PACKAGE.
5283 * scmconfig.h.in: Regenerated.
5285 * snarf.h: g++ says it's non-portable not to specify the first
5286 argument in a varargs declaration. I introduced the first
5287 argument by using preprocessor conditionals.
5289 Thu Mar 13 21:28:25 1997 Gary Houston <ghouston@actrix.gen.nz>
5291 * ioext.c (scm_read_delimited_x): use RO string macros for delims.
5292 (scm_freopen): use RO string macros for filename and modes.
5293 (scm_duplicate_port, scm_fdopen): use RO string macros for modes.

5299 use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
5301 * net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
5302 use SCM_ROSTRINGP and SCM_ROCHARS.

5306 * unif.c (scm_array_set_x): Cast ICHR (obj) to char if storing in
5309 * ramap.c (scm_ra_matchp, scm_array_fill_int, racp,
5310 scm_array_index_map_x, raeql_1, scm_array_equal_p): Completed
5311 support for byte vectors.
5313 * print.c (scm_iprin1): Limit number of vector elements printed
5314 according to pstate->length.
5316 Thu Mar 13 00:12:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5318 * backtrace.c (scm_display_error_message): don't segv if message
5321 * error.h: prototype for scm_error_scm.
5323 * error.c (scm_error_scm): new procedure, reimplements scm-error
5324 in C and uses scm_error.
5326 Tue Mar 11 03:51:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5328 * read.c (scm_read_hash_extend): make scm_read_hash_procedures a
5329 pointer to the Scheme variable read-hash-procedures and intern it
5330 in scm_init_read. Modify scm_read_hash_extend and
5331 scm_get_hash_procedure to use the pointer.
5333 Mon Mar 10 06:28:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5335 * read.h (SCM_N_READ_OPTIONS): increase SCM_N_READ_OPTIONS to 4.
5336 (SCM_KEYWORD_STYLE): defined.
5338 * read.c (scm_read_opts): add a keywords option. This isn't a
5339 boolean option, in case someone wants to add support for DSSSL
5341 Setup scm_keyword_prefix symbol.
5342 (scm_lreadr): Only process keywords if SCM_KEYWORD_STYLE is
5344 I've left keyword support disabled by default, since it doesn't
5345 seem to break the module system and it gives R4RS standard behaviour.
5346 It can be reactivated with (read-set! keywords 'prefix).
5348 Sun Mar 9 14:14:39 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5350 * arbiters.c (scm_make_arbiter): Bugfix: Must SCM_DEFER_INTS
5351 before constructing arbiter.
5353 * eval.c (scm_m_define): Bugfix: Check that the object is a
5354 closure before setting the procedure property!
5356 * ports.h: Removed prototype for scm_ungetc_char_ready_p.
5358 * ports.c: Removed `ungetc-char-ready?'.
5360 Sat Mar 8 00:27:05 1997 Gary Houston <ghouston@actrix.gen.nz>
5362 * read.c (scm_init_read): intitialise scm_read_hash_procedures
5363 (idea from Mikael: make it a pair so scm_permanent object only
5365 (scm_read_hash_extend): don't call scm_permanent_object.
5366 (ideas from Mikael): if chr is already in the list, replace its
5367 procedure instead of appending it again. If proc is #f, remove
5369 (scm_get_hash_procedure): take CDR of scm_read_hash_procedures.
5371 * strports.c (scm_read_0str, scm_eval_0str): update scm_read usage.
5373 * gdbint.c (gdb_read): update scm_lreadr usage.

5385 (scm_get_hash_procedure): new procedure.
5386 (scm_lreadr): use scm_get_hash_procedure instead of an argument
5387 for extended # processing.
5388 (scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
5389 scm_read_token): remove case_i, sharp arguments. Change callers.
5391 Fri Mar 7 08:58:21 1997 Gary Houston <ghouston@actrix.gen.nz>
5393 * read.h (SCM_N_READ_OPTIONS): increase to 3.
5394 (SCM_CASE_INSENSITIVE_P): define.
5396 * read.c: add case-insensitive option to scm_read_opts.
5397 (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
5398 to determine whether to convert symbol case.
5399 (default_case_i): definition removed.
5400 * read.c (scm_read_token): if case_i, downcase ic before doing
5403 Sat Mar 8 03:49:03 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5405 * configure.in: Added configuration option `guile-debug'.
5406 Configure with --enable-guile-debug if you want a bunch of extra
5407 functions used for debugging when developing Guile.
5409 * acconfig.h: Added new preprocessor symbol GUILE_DEBUG.
5411 * procs.c (make-cclo): New undocumented debugging procedure: Make
5412 compiled closure with internal procedure PROC and length LENGTH.
5413 Only compiled if GUILE_DEBUG is defined.
5415 * debug.c: Only include `debug-hang' if GUILE_DEBUG is defined.
5417 * print.c: Put #ifdef GUILE_DEBUG around `current-pstate'.
5419 * ports.c: Changed preprocessor symbol DEBUG --> GUILE_DEBUG.
5421 * eval.c (SCM_CEVAL): Added code sections for handling of rpsubrs
5422 with 3 or more args internally to the evaluator.
5424 Fri Mar 7 19:38:18 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5426 * eval.c (SCM_CEVAL): Added code sections for handling of asubrs
5427 with 3 or more args internally to the evaluator. This is mainly
5428 because we don't want to pass entry and exit points of the
5429 debug support twice, but it also seems to increase the speed of
5430 the evaluator for such calls (e. g. (+ 1 2 3)).
5432 * backtrace.c (scm_display_application): New procedure:
5433 display-application; Set fancy printing parameters individually
5434 for different types of display (backtrace, error, application).
5435 (These should of course be customizable!)
5437 * debug.h (SCM_RESET_DEBUG_MODE): Bugfix: The old code didn't
5438 clear the CHECK-flags.
5440 Thu Mar 6 00:53:02 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5442 * tags.h, eval.c (iqq): Fixes to comments about SCM_ECONSP.
5444 Wed Mar 5 23:31:21 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5446 * tags.h (SCM_ECONSP, SCM_NECONSP): Bugfix: Discriminate structs
5447 from pairs with a GLOC in the car.
5449 * symbols.c (msymbolize): Bugfix: Also initialize SCM_SYMBOL_HASH,
5450 otherwise `symbol-hash' will behave badly.
5451 (scm_symbol_hash): Bugfix: Must msymbolize if tc7_ssymbol, othwise
5452 we get segmentation fault!
5454 * symbols.c: Added #include "weaks.h". New functions:
5455 `builtin-bindings' and `builtin-weak-bindings'. (These will be
5456 moved to an extraneous library when we split libguile.)
5458 Tue Mar 4 19:50:07 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5460 * filesys.c (scm_stat): stat now takes fport arguments too as
5461 documented in the manual.
5463 Mon Mar 3 07:11:33 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5465 * debug.c (scm_single_step): Bugfix: Call continuation with
5466 scm_call_continuation instead of throwing to it.
5468 Mon Mar 3 09:07:56 1997 Gary Houston <ghouston@actrix.gen.nz>
5470 * ports.c (scm_char_ready_p): bug fix: in SCM_PROC char-ready's
5471 argument wasn't declared to be optional.
5473 Sun Mar 2 16:34:40 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5475 * stime.c (scm_init_stime): Add feature "current-time".
5477 Sun Mar 2 06:37:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5479 * throw.h: prototype for scm_exit_status.
5480 * throw.c (scm_handle_by_message): if a 'quit is caught, use its
5481 args to derive an exit status. Allows (quit) to work from a
5483 (scm_exit_status): new function.
5486 Sat Mar 1 00:09:15 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5488 * eval.c (scm_deval): Removed some old code.
5489 (ENTER_APPLY): Bugfix: Reset apply-frame trap on trap as is done
5491 (ENTER_APPLY, scm_deval): Reset trace flag on apply-frame and
5494 * symbols.c (msymbolize): Bugfix: Must initialize property list to
5497 * procs.c: Introduce the existent C function scm_thunk_p at the
5498 Scheme level as well.
5500 Wed Feb 26 12:53:58 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5502 * symbols.c, symbols.h (scm_symbol_value0): New function. Can be
5503 used from C to easily lookup the value of a symbol in the current
5506 Tue Feb 25 00:14:10 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5508 * unif.c (scm_init_unif): Added #include "unif.x". (There are two
5509 scm_init_unif in this file. This will also fix a previous problem
5512 * configure.in: Added AM_MAINTAINER_MODE
5514 Fri Feb 21 23:07:26 1997 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5516 * gdb_interface.h (GDB_INTERFACE): Added some (void *) casts to
5519 Fri Feb 21 18:00:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5521 * Makefile.am (EXTRA_libguile_la_SOURCES): New variable to hold
5522 source files that are not always included in libguile but should
5523 have their dependencies calculated by automake. This variable is
5524 recognized by automake, no further magic is needed.
5525 (libguile_la_DEPENDENCIES): Changed to @LIBLOBJS@. Libtool wants
5526 to deal exclusively with *.lo files, as it seems. The *.o files
5527 are built automatically when the corresponding *.lo file gets
5530 Wed Feb 19 14:04:23 1997 Jim Blandy <jimb@floss.cyclic.com>
5532 * list.h (scm_list_cdr_ref): Delete prototype; function no longer
5535 Thu Feb 13 21:44:07 1997 Gary Houston <ghouston@actrix.gen.nz>
5537 * unif.c (scm_array_set_x): minor change to argument error checking.
5539 Tue Feb 11 18:19:47 1997 Jim Blandy <jimb@floss.cyclic.com>
5541 * Makefile.am (libguile_la_SOURCES): Remove backtrace.c, debug.c,
5542 inet_aton.c, srcprop.c, stacks.c, and strerror.c from this list.
5543 They should only be included in the library at configure.in's
5545 (libguile_la_LDADD): Include the appropriate .lo files here.
5546 (libguile_la_DEPENDENCIES): List the corresponding .o files here,
5547 so we know when to build them (and their .lo bretheren).
5548 * configure.in (LIBLOBJS): New substituted variable. We let
5549 configure decide which .o files to include in LIBOBJS, and then
5550 put the corresponding list of .lo files in LIBLOBJS. The latter
5551 is what we pass to libtool.
5552 * Makefile.in, configure: regenerated.
5554 Mon Feb 10 00:08:08 1997 Mikael Djurfeldt <mdj@kenneth>
5556 * symbols.c (scm_sysintern0): New function. Contains the core of
5557 old scm_sysintern but doesn't take a second value argument.
5558 (scm_sysintern): Now uses scm_sysintern0.
5559 (scm_sysintern_no_module_lookup): Renamed to
5560 scm_sysintern0_no_module_lookup and doesn't take a second value
5561 argument any longer.
5563 * symbols.h (scm_sysintern0: Added declaration.
5565 * options.c (scm_init_opts): Use scm_sysintern0 instead of
5566 scm_sysintern when interning option keys. Otherwise we risk
5567 destroying the values of already interned variables.
5569 * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
5570 scheme-level boolean (use SCM_NFALSEP).
5572 * backtrace.c (scm_init_backtrace): Make Scheme-level variable
5574 (scm_backtrace): New function. (C version of old function from
5575 boot-9.scm) Motivation: Make it possible to display backtraces
5576 without depending on boot-9.scm. (I'm uncertain if this
5577 motivation is good enough...)
5579 * root.h (scm_root_state): Add member the_last_stack_var.
5580 (scm_the_stack_var): Defined to scm_root->the_last_stack_var.
5582 * root.c (mark_root): Mark scm_the_last_stack_var.
5584 * init.c (scm_start_stack): Initialize scm_the_last_stack_var to
5587 Sun Feb 9 18:04:41 1997 Mikael Djurfeldt <mdj@kenneth>
5589 * throw.c (mark_lazy_catch, free_lazy_catch): Removed.
5590 1. mark_lazy_catch didn't mark the smob.
5591 2. Both functions above have standard variants:
5592 (lazy_catch_funs): Changed mark_lazy_catch --> scm_mark0,
5593 free_lazy_catch --> scm_free0.
5595 Fri Feb 7 17:30:26 1997 Jim Blandy <jimb@floss.cyclic.com>
5597 * throw.c (scm_internal_lazy_catch): New function.
5598 (scm_lazy_catch): Rewritten to use it.
5599 (scm_ithrow): Handle the new lazy catch representation.
5600 Use SCM_LAZY_CATCH_P, instead of assuming that any wind list entry
5601 that doesn't have a jmpbuf is a lazy catch clause.
5602 (tc16_lazy_catch, struct lazy_catch, mark_lazy_catch,
5603 free_lazy_catch, print_lazy_catch, lazy_catch_funs,
5604 make_lazy_catch, SCM_LAZY_CATCH_P): Support funs, including a new
5606 (scm_init_throw): Register the new lazy-catch smob type.
5607 * throw.h (scm_internal_lazy_catch): decl for new function.
5609 * throw.c (scm_internal_catch): Doc fixes.
5611 * alloca.c: New file, needed to support the AC_FUNC_ALLOCA call in
5612 configure.in. Including this might cause problems if applications
5613 that link against libguile include their own copies of alloca, but
5614 if they're using autoconf, they should be adding libguile to LIBS
5615 before calling AC_FUNC_ALLOCA anyway, in which case they'll find
5616 the copy in libguile, and things will be okay. (I think.)
5618 Thu Feb 6 03:10:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5620 * strop.c (scm_string_upcase_x, scm_string_downcase_x): moved from
5622 strop.h: move prototypes too.
5624 Wed Feb 5 08:33:00 1997 Gary Houston <ghouston@actrix.gen.nz>
5626 * posix.c (scm_init_posix): don't intern EINTR since it's now done
5629 * ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
5630 etc. I deleted them from filesys.c long ago, but didn't
5631 notice they were here too (although ineffective since
5632 sys/stat.h wasn't included).
5634 Tue Feb 4 18:17:50 1997 Tom Tromey <tromey@cygnus.com>
5636 * eval.c: Don't define alloca in GCC case. gcc will automatically
5637 use __builtin_alloca if appropriate.
5639 Tue Feb 4 16:57:40 1997 Jim Blandy <jimb@floss.cyclic.com>
5641 * eval.c (safe_setjmp): New function: trivial wrapper for setjmp.
5642 (SCM_CEVAL, SCM_APPLY): Call it, instead of setjmp, to make sure
5643 that values of automatic variables are preserved. See comments
5644 for safe_setjmp for details.
5646 Change from Thomas Morgan:
5647 * variable.c: Include eq.h.
5648 (var_equal): New function.
5649 (variable_smob): Use var_equal as the discriminator for variables.
5651 * throw.c (s_throw): Remove extraneous declaration.
5653 * configure.in: Call AC_FUNC_ALLOCA, to see if we have alloca.
5654 * eval.c: Add necessary CPP cruft to support that.
5655 * configure, Makefile.in, scmconfig.h.in: regenerated.
5657 Change from Thomas Morgan:
5658 * procprop.c (scm_procedure_properties): Convert the Scheme
5659 boolean returned by scm_procedure_p into a C boolean before using
5660 it as a condition for SCM_ASSERT.
5661 (scm_procedure_property): Likewise.
5663 * simpos.c (SYSTNAME): Accept both 'unix' and '__unix' as
5664 indications of Unixness.
5667 Tue Feb 4 05:07:35 1997 Gary Houston <ghouston@actrix.gen.nz>
5669 * net_db.c (scm_lnaof): change scheme name from lnaof to inet-lnaof.
5671 Mon Feb 3 06:12:37 1997 Gary Houston <ghouston@actrix.gen.nz>
5673 * read.c (scm_lreadr): use scm_misc_error to improve one of the
5674 "unknown # object" error messages.
5676 * strop.c (scm_i_index, scm_i_rindex): combine into one procedure
5677 (scm_i_index) and declare it static. Add a 'direction' argument
5678 to indicate what way the search should go.
5679 (scm_i_index): throw out-of-range error instead of wrong-type-arg
5681 (scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
5682 strop.h: remove scm_i_index, scm_i_rindex prototypes.
5684 Fri Jan 31 04:33:11 1997 Gary Houston <ghouston@actrix.gen.nz>
5686 * ioext.c, ioext.h: remove obsolete _sys_ from 9 procedure names.
5688 * posix.c (scm_fork): Scheme name changed from fork to primitive-fork,
5689 to avoid clash with various scsh forks.
5691 Thu Jan 30 20:14:09 1997 Mikael Djurfeldt <mdj@syk-0606.pdc.kth.se>
5693 The following two changes (ramap.c, throw.c) are motivated by the
5694 apparent unportability of forward declarations of static arrays of
5695 the form `static foo bar[];'.
5697 * ramap.c (scm_array_fill_x): Moved above scm_array_fill_int.
5698 (ra_rpsubrs, ra_asubrs): Moved to the top of array code.
5700 * throw.c (scm_throw): Moved above scm_ithrow.
5702 * options.h: Removed the extern declarations of scm_yes_sym and
5703 scm_no_sym since these are static.
5705 Fri Jan 24 06:16:32 1997 Gary Houston <ghouston@actrix.gen.nz>
5707 * ports.c: add SCM_PROC declarations for pt-size and pt-member.
5709 * Makefile.am: remove AWK=@AWK@.
5710 Add a rule for generating errnos.list.
5711 (CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
5713 * configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
5714 don't extract errnos, just set a variable (avoids the
5715 need to recompile error.c just because configure is run.)
5717 * unif.h: update prototypes.
5718 * unif.c (scm_uniform_array_read,write): change the offset and
5719 length arguments to start and end, for consistency.
5721 * __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
5723 * ioext.h: update prototypes.
5724 * ioext.c (scm_read_delimited_x): replaces scm_read_line and
5725 scm_read_line_x, it's a more general procedure using an
5726 interface from scsh. read-line and read-line! are now defined
5728 Note that the new read-line trims the terminator
5729 by default, previously it was appended to the returned string. An
5730 optional argument specifies how to process the terminator (scsh
5731 compatible). For the old behaviour: (read-line port 'concat).
5732 scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
5733 returns a pair, but is converted to multiple values if the scsh
5736 socket.h: update prototypes.
5737 * socket.c (scm_recvfrom): for consistency with other procedures,
5738 take start and end as separate optional arguments.
5739 (scm_recv, scm_recvfrom): don't allow the second argument
5740 to be a size, only a buffer. Change the scheme names to
5741 recv! and recvfrom!. Don't return the buffer.
5743 * ioext.h, posix.h: move prototypes too.
5744 * ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
5745 moved back from posix.c to ioext.c. Also move #includes of "genio.h"
5746 "read.h" and "unif.h".
5747 * ioext.c: include "chars.h"
5749 Mon Jan 20 19:54:49 1997 Marius Vollmer <mvo@zagadka.ping.de>
5751 * dynl.c: The dynamic linking and module registration functions
5752 are now defined even when dynamic linking is not available for the
5753 host system. Some of their functionality can be done without
5754 dynamic linking; when it's really needed, they throw errors.
5756 Thu Jan 16 16:39:29 1997 Marius Vollmer <mvo@zagadka.ping.de>
5758 * configure.in: Only define DYNAMIC_LINKING when one of the system
5759 dependent functions is detected.
5760 * dynl.c (scm_dynamic_func): New function to get the address of a
5761 function in a dynamic object.
5762 (scm_dynamic_call, scm_dynamic_args_call): Accept the values
5763 produced by scm_dynamic_func as the thing to call.
5765 Sun Jan 12 21:09:42 1997 Marius Vollmer <mvo@zagadka.ping.de>
5767 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c: Restructured.
5768 (scm_register_module_xxx, scm_registered_modules,
5769 scm_clear_registered_modules): New functions.
5771 Sat Jan 11 21:37:15 1997 Marius Vollmer <mvo@zagadka.ping.de>
5773 * symbols.c (scm_sysintern): Renamed to
5774 scm_sysintern_no_module_lookup.
5775 (scm_sysintern): New function to take the place of the old
5776 scm_sysintern. It uses the current toplevel lookup closure to give
5777 the symbol its value. This is a temporary hack to put packages
5778 like gtcltk into their own module.
5779 (scm_can_use_top_level_lookup_closure_var): New variable to tell
5780 us whether `scm_top_level_lookup_closure_var' has been initialized
5782 * eval.c (scm_init_eval): Set it.
5784 Sat Jan 18 00:03:31 1997 Gary Houston <ghouston@actrix.gen.nz>
5786 * fports.c (scm_open_file): pass errno to scm_syserror_msg.
5787 * filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
5789 * filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
5791 (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
5792 scm_sys_dup): deleted: FD capability will be added to other
5794 Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
5795 scm_fd_free, fd_smob, scm_intern_fd.
5796 (scm_open): renamed from scm_sys_open. Return a port instead of
5797 an FD object. Make the mode argument optional.
5798 (scm_sys_create): deleted, it's just a special case of open.
5799 (scm_init_filesys): move interning of constants O_CREAT etc.,
5800 here (were previously using SCM_CONST_LONG macro).
5801 Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
5803 (numerous _sys_ procedures): remove gratuitous _sys_ from names.
5804 include "fports.h" and <stdio.h>
5805 (scm_stat, scm_select): don't support FD objects.
5807 * error.h: adjust scm_syserror_msg prototype.
5808 * error.c (scm_syserror_msg): take an extra argument for errno.
5809 Using the global value didn't always work, since it could be
5810 reset by procedure calls in the message or args arguments.
5812 * fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
5813 I don't understand why the check was there (and what about the
5816 * strop.c (scm_string_copy): allow shared substrings to be copied.
5818 * unif.h: corresponding change to prototypes.
5819 * unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
5820 recognize two new optional arguments: offset and length. Allow
5821 the port argument to be an integer (file descriptor, for scsh).
5822 Include <unistd.h> for "read" prototype.
5824 Tue Jan 14 02:42:02 1997 Gary Houston <ghouston@actrix.gen.nz>
5826 * socket.c: don't include filesys.h.
5828 Mon Jan 13 03:47:04 1997 Gary Houston <ghouston@actrix.gen.nz>
5830 * Makefile.am: add AWK=@AWK@ (?)
5832 * Makefile.am (EXTRA_DIST): add errnos_cnvt.awk, errnos.default,
5834 Add a rule to generate errnos.c from errnos.
5835 * error.c (scm_init_error): include errnos.c.
5836 * errnos_cnvt.awk: new file, converts the list of errno codes to
5838 * errnos_get.c: new file.
5839 * errnos.default: new file, contains errnos to try if they can't
5840 be extracted from errno.h.
5841 * configure.in: if using GCC, try and extract errno codes from
5845 Sat Jan 11 14:47:00 1997 Marius Vollmer <mvo@zagadka.ping.de>
5847 * configure.in: Replaced AC_PROG_RANLIB with AM_PROG_LIBTOOL.
5848 * Makefile.am: Made libguile into a libtool library.
5849 * PLUGIN/guile.config: Removed "-L ../libguile" from xtra_cflags.
5850 Set libtool_libs to indicate that libguile is a libtool library.
5851 See guile/ChangeLog for details.
5852 * .cvsignore: ignore "*.lo", the libtool library objects.
5854 Wed Jan 8 06:54:54 1997 Gary Houston <ghouston@actrix.gen.nz>
5856 * net_db.c (scm_getserv): add missing SCM_ALLOW_INTS.
5857 use htons in getservbyport argument.
5859 Tue Jan 7 18:11:24 1997 Jim Blandy <jimb@floss.cyclic.com>
5861 * ports.h (SCM_PTOBNUM): Removed extraneous semicolon.
5862 * smob.h: (SCM_PTOBNUM): Removed entirely; this definition is a
5865 * objprop.c (scm_object_property): No need to take the CDR of the
5866 value returned by scm_object_properties, since Aug 20 change.
5868 * configure.in: When checking for struct linger, #include
5869 <sys/types.h> as well as <sys/socket.h>. I've never known
5870 <sys/types.h> to cause any portability problems, and Solaris's
5871 <sys/socket.h> needs it.
5872 * configure: Rebuilt.
5874 I think the Sun compiler has chosen a perverse way to interpret
5875 ANSI declarations combined with K&R definitions. We'll
5876 appease it a little bit. But when it invades France, we fight.
5877 * print.c (scm_iprlist): Change 'tlr' argument to an int.
5878 * print.h (scm_iprlist): Here too.
5879 * numbers.c (scm_divbigdig): Change definition to match
5880 declaration in numbers.h.
5881 * unif.c (scm_makflo): Change definition to match declaration in
5884 * init.c (scm_boot_guile): Don't return the value of
5885 scm_boot_guile_1. This function doesn't return a value;
5886 scm_boot_guile_1 doesn't return a value (or return at all).
5888 * eval.c (unmemocopy): Add a semicolon to appease the Sun
5891 * simpos.c (SYSTNAME): Add case for AIX; otherwise it won't
5892 compile. I have a feeling this function is a bad idea anyway ---
5893 one should always test for features, not systems.
5895 * smob.h (SCM_SMOBNUM, SCM_PTOBNUM): Remove extraneous
5896 semicolons. Only pure luck kept this from being noticed earlier.
5898 Tue Jan 7 15:04:06 1997 Mikael Djurfeldt <mdj@kenneth>
5900 * socket.c (scm_recvfrom): Added missing semicolon.
5902 Mon Jan 6 20:39:08 1997 Gary Houston <ghouston@actrix.gen.nz>
5904 * socket.c (scm_recvfrom): allow buff_or_size to be a list containing
5905 the buffer and start and end positions for scsh networking
5908 Sun Jan 5 13:53:53 1997 Jim Blandy <jimb@floss.cyclic.com>
5910 * configure.in: Revert previous change to this file; the problem
5911 is due to transient automake weirdness.
5912 * configure: Rebuilt.
5914 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in, not
5915 PLUGIN/guile.libs. configure generates the latter from the former.
5916 * Makefile.in: Rebuilt.
5918 * configure.in: Call AM_PROG_INSTALL; the automake manual says we
5919 need this if we install scripts, like guile-snarf.
5920 * configure: Rebuilt.
5922 Thu Jan 2 01:56:38 1997 Marius Vollmer <mvo@zagadka.ping.de>
5924 * Makefile.am (EXTRA_DIST): Added DYNAMIC-LINKING
5926 Sat Dec 28 19:14:01 1996 Gary Houston <ghouston@actrix.gen.nz>
5928 * socket.c (scm_addr_vector): fix faulty scm_listify.
5930 Sat Dec 28 13:55:58 1996 Marius Vollmer <mvo@zagadka.ping.de>
5932 * read.c (scm_lreadr): Encountering EOF after skipping a SCSH
5933 style block comment is no longer considered an error.
5935 Fri Dec 27 13:44:23 1996 Marius Vollmer <mvo@zagadka.ping.de>
5937 * PLUGIN/guile.libs.in: New file.
5938 * PLUGIN/guile.libs: Removed from repository.
5939 * configure.in: Create PLUGIN/guile.libs from
5940 PLUGIN/guile.libs.in. This is for including additonal libraries
5941 needed for dynamic linking.
5942 * Makefile.am (EXTRA_DIST): Distribute PLUGIN/guile.libs.in
5943 instead of PLUGIN/guile.libs.
5945 * Makefile.am: Added explicit dependency "dynl.o: dynl.x".
5947 Sun Dec 22 23:06:14 1996 Jim Blandy <jimb@floss.cyclic.com>
5949 * list.c (scm_delq_x, scm_delv_x, scm_delete_x): Delete all
5950 occurrences of the given element from the list, not just the
5951 first. This is how the Emacs Lisp functions behave, how the
5952 analogous Common Lisp functions behave, and (I believe) how the
5953 older Maclisp functions worked. I realize that this change may
5954 break code, but it seemed better to break it before the Guile
5957 * gc.c (scm_protect_object, scm_unprotect_object): New functions.
5958 Their prototypes were already present in gc.h, but they weren't
5960 (scm_init_storage): Initialize scm_protects.
5961 * root.c (scm_protects): New element of scm_sys_protects.
5963 * net_db.h (scm_init_net_db): Fix spelling from scm_init_netdb.
5965 Sat Dec 21 15:38:32 1996 Jim Blandy <jimb@floss.cyclic.com>
5967 * libguile.h: Added #include "libguile/net_db.h".
5969 * libguile.h: Don't #include "libguile/libpath.h", contrary to Oct
5970 30 change. That file is only meant for communication between the
5971 configuration process and load.c. If code linked against libguile
5972 wants to get at the paths mentioned in libpath.h, it can call
5973 functions declared in load.h.
5975 Sat Dec 21 14:50:42 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
5977 * libguile.h: Removed #include "libguile/fdsocket.h"
5979 * net_db.c: Added #include <sys/socket.h>.
5981 Sat Dec 21 00:33:03 1996 Gary Houston <ghouston@actrix.gen.nz>
5983 * filesys.c (scm_input_waiting_p): use select in preference to
5984 FIONREAD, since the latter doesn't detect EOF.
5985 Throw error if neither select nor FIONREAD available.
5987 * socket.c (scm_connect): take a port, not a fd object.
5988 (scm_fill_sockaddr): throw an error if fam is not recognised.
5989 (scm_bind): use scm_fill_sockaddr.
5990 (scm_listen): take a port, not a fd object.
5991 (scm_accept): take and return a port. return #f in the car if
5992 address can't be got
5993 (scm_sock_fd_to_port): new procedure.
5994 (scm_socket): use scm_sock_fd_to_port.
5995 (scm_addr_vector): throw error if unrecognised address type.
5996 take an extra argument with the calling procedure name.
5997 (scm_getsockname): take a port. return #f if address can't be got.
5998 (scm_getpeername): take a port. return #f if address can't be got.
5999 (scm_recvfrom): take a port. return #f for address component if can't
6001 (scm_sendto, scm_socketpair, scm_getsockopt scm_shutdown,
6002 scm_setsockopt, scm_recv, scm_send): take a port not a fd object.
6004 Fri Dec 20 23:06:53 1996 Jim Blandy <jimb@floss.cyclic.com>
6006 * throw.c (scm_internal_catch): Make body funcs and handler funcs
6007 use separate data pointers, to allow them to be designed
6008 independently and reused.
6009 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message):
6010 Renamed from catch_body, catch_handler, and uncaught_throw; made
6012 (struct scm_catch_body_data): Renamed from catch_body_data; moved
6014 (scm_catch): Use the above.
6015 (scm_throw): Don't bother printing a message for an uncaught
6016 throw; we establish a default handler in init.
6017 * throw.h (scm_internal_catch): Prototype updated.
6018 (scm_body_thunk, scm_handle_by_proc, scm_handle_by_message): New
6020 (struct scm_body_thunk_data): New structure, used as data
6021 argument to scm_body_thunk.
6022 * init.c (struct main_func_closure): New structure, packaging up
6023 the data to pass to the user's main function.
6024 (scm_boot_guile): Create one. Pass it to scm_boot_guile_1.
6025 (scm_boot_guile_1): Pass it through to invoke_main_func. Use
6026 scm_internal_catch to establish a catch-all handler, using
6027 scm_handle_by_message. This replaces the special-case code in
6029 (invoke_main_func): Body function for scm_internal_catch; invoke
6030 the user's main function, using the main_func_closure pointer to
6031 decide what to pass it.
6032 * root.c (struct cwdr_body_data): Remove handler_proc member.
6033 (cwdr): Use scm_handle_by_proc instead of cwdr_handler.
6034 (cwdr_handler): Removed.
6036 Thu Dec 19 00:00:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6038 * socket.h (SCM_P): update bind prototype.
6039 * socket.c (scm_init_socket): intern PF_UNSPEC, PF_UNIX, PF_INET.
6040 include "feature.h".
6041 (scm_socket): return a port, not a file descriptor object.
6042 include "fports.h" and <unistd.h>
6043 (scm_bind): take a port, not a file descriptor object.
6044 take an extra argument for address args.
6046 * net_db.c (scm_init_net_db): intern INADDR_ANY, INADDR_BROADCAST,
6047 INADDR_NONE, INADDR_LOOPBACK.
6049 Tue Dec 17 22:58:26 1996 Gary Houston <ghouston@actrix.gen.nz>
6051 * init.c: include net_db.h and not fdsocket.h.
6052 (scm_boot_guile_1): call scm_init_net_db and not scm_init_fdsocket.
6054 * Makefile.am: corresponding changes.
6055 * socket.h: renamed from fdsocket.h, fix names.
6056 * net_db.h: renamed from socket.h, fix names.
6057 * socket.c: renamed from fdsocket.c.
6058 remove _sys from procedure names.
6059 (scm_init_socket): rename from scm_init_fdsocket. include socket.x.
6060 add "socket" to features list.
6061 * net_db.c: renamed from socket.c.
6062 remove _sys from procedure names.
6063 (scm_init_net_db): rename from scm_init_socket. include net_db.x.
6064 add "net-db" to features list.
6065 include "net_db.h". don't include <sys/socket.h> or
6068 Thu Dec 19 14:03:24 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6070 * tags.h (scm_tags): Removed comma at end of last enumerator.
6072 Thu Dec 19 02:54:59 1996 Jim Blandy <jimb@floss.cyclic.com>
6074 Don't use GCC extensions to allocate space for debugging frames.
6075 (Here he goes again! Why do we put up with this?!)
6076 * debug.h (scm_debug_frame): Make the 'vect' member a pointer to
6077 an scm_debug_info structure, not an in-line array of them. Add
6078 'info' member, to say how many vect elements we've used, for eval
6080 * eval.c (SCM_CEVAL): Use alloca to allocate space for vect. Use
6081 a new variable debug_info_end to mark the end of vect, instead of
6082 the address of the 'info' pointer itself.
6083 [DEVAL] (ENTER_APPLY, SCM_CEVAL, SCM_APPLY): Remove casts of
6084 &debug to scm_debug_frame *; debug is a real scm_debug_frame now.
6085 (SCM_APPLY): Explicitly allocate space for debug.vect.
6086 * debug.c (scm_m_start_stack): Same, for vframe.vect.
6087 * stacks.c: Adjusted for new debug frame structure.
6088 (RELOC_INFO, RELOC_FRAME): New macros.
6089 (stack_depth, read_frames): Use them, and new scm_debug_frame
6090 element 'info', instead of magically knowing that eval frames have
6091 an info pointer sitting after vect.
6092 (scm_make_stack, scm_stack_id, scm_last_stack_frame): Use
6094 (scm_init_stacks): Formatting tweaks.
6096 Wed Dec 18 14:57:57 1996 Jim Blandy <jimb@floss.cyclic.com>
6098 Give GCC more control flow information, so it can be sure that
6099 variables aren't used uninitialized.
6100 * error.h (scm_error, scm_syserror, scm_syserror_msg,
6101 scm_sysmissing, scm_num_overflow, scm_out_of_range,
6102 scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
6103 scm_misc_error): Tell GCC that these functions never return.
6104 * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
6105 out the field type, call abort if SCM_ASSERT returns, to placate
6107 * stacks.c (scm_make_stack, scm_last_stack_frame): abort if
6108 scm_wta ever returns. We can't handle this case anyway, and this
6109 gives the optimizer more information.
6110 * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
6111 scm_wta ever returns.
6113 In some cases, the code is fine, but GCC isn't smart enough to
6114 figure that out; this usually happens when one variable is only
6115 initialized and used when a particular condition holds true, and
6116 we know that condition will never change within a given invocation
6117 of the function. In this case, we simply initialize the variables
6118 to placate the compiler, hopefully to a value which will cause a
6119 crash if it is ever actually used.
6120 * print.c (scm_iprin1): Initialize mw_pos.
6121 * read.c (scm_lreadrecparen): Initialize tl2, ans2.
6122 * throw.c (scm_ithrow): Initialize dynpair.
6123 * unif.c (scm_uniform_vector_ref): Initialize cra.
6124 * struct.c (init_struct): Initialize prot.
6125 * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
6127 * strports.c (scm_eval_0str): Don't return uninitialized garbage
6128 if EXPR contains no expressions.
6130 Wed Dec 18 11:43:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
6132 * eval.c, debug.h: Revert changes of Dec 16 and Nov 21. They
6133 cause an infinite loop (???). So much for the algebraic
6134 equivalency of variable-sized arrays and alloca...
6136 Tue Dec 17 20:29:03 1996 Marius Vollmer <mvo@zagadka.ping.de>
6138 * backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns
6139 a SCM boolean, not a C boolean.
6141 Sat Dec 14 23:21:45 1996 Marius Vollmer <mvo@zagadka.ping.de>
6143 * gc.c (SCM_MTRIGGER_HYSTERESIS): New memory management parameter.
6144 (scm_must_malloc, scm_must_realloc): Added a hysteresis to the
6145 rules for raising scm_mtrigger. Previously, unfortunate but not
6146 unlikely circumstances could result in almost constant invokation
6147 of the gc. Now, this situations should be less likely, but they
6148 are not prevented completely.
6150 Tue Dec 17 16:19:07 1996 Jim Blandy <jimb@totoro.cyclic.com>
6152 * numbers.c (scm_fuck): Procedure removed; looks like old test
6154 * numbers.h: Prototype removed.
6156 Mon Dec 16 18:20:32 1996 Jim Blandy <jimb@totoro.cyclic.com>
6158 * debug.h (scm_debug_frame): Change `vect' member from an in-line
6159 array to a pointer, to match my Nov 21 change in eval.c.
6161 Fri Dec 13 16:12:14 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6163 * libguile.h: Added #include "libguile/backtrace.h", #include
6164 "libguile/stacks.h".
6166 * strings.c (scm_string scm_make_string scm_string_ref
6167 scm_string_set_x scm_string_equal_p scm_string_append):
6168 Bugfix according to scm patch from Aubrey Jaffer:
6169 Corrected long-standing
6170 (not (eqv? (integer->char 128)
6171 (string-ref (make-string 1 (integer->char 128)) 0)))
6172 bug found by John Kozak <jk@noontide.demon.co.uk>.
6174 * strports.c, strports.h: Make scm_eval_0str return the value of
6175 the last expression evaluated (previously, it returned void).
6177 * strports.c, strports.h: New function: scm_read_0str. Does what
6180 Tue Dec 10 23:38:43 1996 Gary Houston <ghouston@actrix.gen.nz>
6182 * simpos.c (scm_getenv): return #f if string can't be found in the
6183 environment instead of throwing an exception, for compatibility
6184 with numerous other systems.
6186 Mon Dec 9 23:23:35 1996 Tom Tromey <tromey@cygnus.com>
6188 * Makefile.am (.c.x): Use guile-snarf.
6189 * configure.in (AC_OUTPUT): Generate guile-snarf; make it
6191 * guile-snarf.in: New file, resurrected from old guile-snarf.sh.
6193 Mon Dec 9 18:36:50 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6195 * backtrace.c (scm_display_error_message): Made non-static, and
6196 renamed from display_error_message.
6197 * backtrace.h (scm_display_error_message): Added extern decl.
6198 * throw.c (uncaught_throw): Use it to display the error message.
6200 Mon Dec 9 10:10:38 1996 Tom Tromey <tromey@cygnus.com>
6202 * inet_aton.c: Use #if 0, not #ifdef 0.
6204 Mon Dec 9 06:36:48 1996 Gary Houston <ghouston@actrix.gen.nz>
6206 * ioext.c (scm_sys_ftell): use scm_long2num instead of SCM_MAKINUM
6207 to convert the returned value.
6208 (scm_sys_fseek): use scm_num2long instead of SCM_INUM to convert
6209 the offset argument.
6211 Sun Dec 8 21:06:38 1996 Jim Blandy <jimb@duality.gnu.ai.mit.edu>
6213 Add new interface to catch/throw, usable from C as well as
6215 * throw.h (scm_catch_body_t, scm_catch_handler_t): New types.
6216 (scm_internal_catch): New function, replaces...
6217 (scm_catch_apply): Deleted.
6218 * throw.c (scm_catch_apply): Deleted; replaced with a more general
6219 mechanism which is a bit more code, but can be used nicely from C
6220 and implement the Scheme semantics as well.
6221 (scm_internal_catch): This is the replacement; it's named after
6222 the analogous function in Emacs.
6223 (scm_catch): Reimplemented in terms of the above.
6224 (struct catch_body_data, catch_body, catch_handler): New
6225 functions, used by scm_catch.
6226 * root.c (cwdr): Reimplemented in terms of scm_internal_catch.
6227 (struct cwdr_body_data, cwdr_body, cwdr_handler): New functions;
6228 support for new cwdr.
6230 * Makefile.am (libpath.h): Re-incorporate Mikael's changes of Wed
6233 Sun Dec 8 17:55:34 1996 Marius Vollmer <mvo@zagadka.ping.de>
6235 * acconfig.h: Added DYNAMIC_LINKING symbol.
6236 * configure.in: Add option and checks for dynamic linking.
6237 * dynl.c, dynl-dl.c, dynl-dld.c, dynl-shl.c, dynl-vms.c,
6238 dynl.h: New files for dynamic linking support.
6239 * Makefile.am (libguile_a_SOURCES):
6241 (modinclude_HEADERS): Added "dynl.h".
6242 (EXTRA_DIST): Added "dynl-dl.c", "dynl-dld.c", "dynl-shl.c" and
6244 * init.c (scm_boot_guile_1): Call
6245 scm_init_dynamic_linking to initialize dynamic linking support.
6247 Thu Dec 5 22:47:53 1996 Marius Vollmer <mvo@zagadka.ping.de>
6249 * init.c (scm_boot_guile_1): Moved `live' variable to the toplevel
6250 (as we Schemers say). It needs to be global, so that I can tweak
6251 it for the proper operation of unexec.
6252 (scm_boot_guile_1_live): New variable, see above.
6254 Sun Dec 1 00:00:49 1996 Tom Tromey <tromey@cygnus.com>
6256 * guile-snarf.sh: Removed.
6257 * PLUGIN/guile.libs: Added dependency for -lm.
6258 * acinclude.m4: Renamed from aclocal.m4.
6259 * PLUGIN/greet: Removed.
6260 * Makefile.am, aclocal.m4: New files.
6261 * configure.in: Updated for Automake.
6263 Thu Nov 28 00:23:55 1996 Marius Vollmer <mvo@zagadka.ping.de>
6265 * eval.c (scm_definedp): Use top_level_lookup_closure_var
6266 and not top_level_lookup_thunk_var.
6268 Wed Nov 27 22:04:19 1996 Jim Blandy <jimb@baalperazim.frob.com>
6270 * Makefile.in (ancillary): List ChangeLog-scm, not ChangeLog.scm.
6272 Wed Nov 27 14:14:56 1996 Marius Vollmer <mvo@zagadka.ping.de>
6274 * eval.c (scm_definedp): Incompatibly changed to be a builtin
6275 Scheme function, instead of syntax. Single argument is now a
6278 Thu Nov 21 20:26:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
6280 * ramap.c (scm_ra_sum, scm_ra_difference, scm_ra_product,
6281 scm_ra_divide): Properly terminate statements passed as arguments
6282 to IVDEP macros. (Thanks to Bernard Urban.)
6284 * eval.c (SCM_CEVAL): Use alloca, not GCC's extensions for arrays
6285 with non-constant sizes. (Thanks to Bernard Urban.)
6287 Thu Nov 21 11:17:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6289 It's an "eval closure", not an "eval thunk." A thunk is a
6290 function of no arguments.
6291 * root.h (struct scm_root_state): Renamed
6292 top_level_lookup_closure_var from top_level_lookup_thunk_var.
6293 (scm_top_level_lookup_closure_var): Renamed from
6294 scm_top_level_lookup_thunk_var.
6295 * root.c (mark_root): Uses changed.
6296 * gdbint.c (gdb_eval, gdb_binding): Uses changed.
6297 * init.c (scm_start_stack): Uses changed.
6298 * eval.c (scm_eval, scm_eval_x, scm_init_eval): Rename uses.
6299 Change scheme-visible name to *top-level-lookup-closure* from
6300 *top-level-lookup-thunk*.
6302 Tue Nov 19 22:43:31 1996 Jim Blandy <jimb@totoro.cyclic.com>
6304 * gc.c (scm_igc, scm_gc_mark): Round up the size of the stack we
6305 pass to scm_mark_locations. (Thanks to Aubrey Jaffer.)
6307 Sun Nov 10 13:35:05 1996 Jim Blandy <jimb@floss.cyclic.com>
6309 * gc.c (struct scm_heap_seg_data): Doc fixes.
6311 * gc.c (scm_gc_sweep): Empty all segments' freelists before
6312 sweeping. Then, prepend each segment's free cells to its
6313 freelist, rather than wiping out the old value. (Thanks to Marius
6316 * gc.c (which_seg, scm_map_free_list, scm_newcell_count,
6317 scm_check_freelist, scm_debug_newcell): New functions and
6318 variables, for debugging freelist problems.
6319 * pairs.h (SCM_NEWCELL): New debugging version added.
6320 * gc.h (scm_debug_newcell): Added extern declaration, used by
6321 debugging version of SCM_NEWCELL.
6323 Sat Nov 9 19:02:46 1996 Jim Blandy <jimb@floss.cyclic.com>
6325 On some systems <libc.h> conflicts with <unistd.h>, and should not
6326 be #included at all.
6327 * aclocal.m4 (GUILE_HEADER_LIBC_WITH_UNISTD): New autoconf macro.
6328 * acconfig.h (LIBC_H_WITH_UNISTD_H): New CPP symbol.
6329 * configure.in: Call it.
6330 * posix.c, filesys.c: Use its results to decide whether or not to
6332 * configure, scmconfig.h.in: Rebuilt with autoconf and
6335 Wed Nov 6 16:19:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
6337 * fports.c (scm_stdio_to_port, scm_open_file): Set the port's
6338 pointer to the stdio stream before calling scm_setbuf0, so the
6339 latter will be able to retrieve it. I'm surprised this didn't
6340 segfault earlier. (Thanks to Christopher Lee.)
6342 Wed Nov 6 16:01:20 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6344 * throw.c (scm_lazy_catch, scm_ithrow): Completed implementation
6347 Sat Nov 2 21:01:48 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6349 * stacks.c, stacks.h (scm_make_stack): Now takes arbitrary
6350 number of stack narrowing specifier pairs. The first specifier in
6351 a pair controls inner border, the second the outer border. A
6352 number means cut that number of frames, a procedure object means
6353 cut until that object is found in operator position in a frame.
6355 * root.c (cwdr): Bugfix.
6357 * read.c: Recording of positions disabled by default.
6359 * procs.c (scm_closure_p): New function.
6361 * posix.c (scm_tmpnam): New function.
6363 * load.c: Added #include "throw.h".
6364 (scm_sys_search_load_path): Bugfix: Don't add an extra '/' if path
6367 * load.c, load.h (scm_read_and_eval_x): New function.
6369 * eval.c: Renamed debug option "deval" to "debug".
6371 (scm_eval_x): `eval!' is no longer accessible from the scheme
6372 level. Motivation: We can't allow operations which introduce
6373 glocs into the scheme level. Guile's type system can't handle
6374 these as data. Use `eval' or `read-and-eval!' as replacement.
6376 * debug.c (scm_m_start_stack): Bugfix: Use SCM_ECONSP instead of
6377 SCM_CONSP since this is a macro!; Set vframe.prev to
6378 scm_last_debug_frame instead of 0. In this way we can look
6379 "above" the virtual start stack frame if we wish.
6380 (scm_debug_hang): New function: Useful for debugging Guile in
6381 certain tricky situations. Will probably be removed later...
6383 * debug.h: Changed semantics of debug option "backtrace". This
6384 option now only indicates whether we want automatic backtrace at
6387 Wed Oct 30 00:31:55 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6389 * ports.c: #include "filesys.h"
6390 (scm_char_ready_p): input_waiting renamed and moved to filesys.c.
6392 * filesys.c, filesys.h (scm_input_waiting_p): Moved from ports.c.
6393 Motivation: This is system specific code which is related to file
6394 I/O. It also may use select. Added code by Gary Houston to
6395 detect presence of character in stdio buffers.
6397 * libguile.h: #include "libguile/libpath.h"
6399 * Makefile.in (libpath.h): Renamed definition of: LIBRARY_PATH -->
6400 SCM_LIBRARY_DIR; Added definitions of: SCM_PKGDATA_DIR,
6401 SCM_SITE_DIR; Install libpath.h among the other include files.
6403 * load.c, load.h (scm_sys_package_data_dir): New function.
6405 Mon Oct 28 11:43:41 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6407 * stacks.h: Bugfix: Don't use tail-array length field as stack
6408 length field! This screwed GC.
6410 Tue Oct 22 01:01:00 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6412 * _scm.h: Added #ifndef around definition of macros min and max.
6414 * __scm.h: Added hooks for threads to plugin to in ints protection
6415 macros: SCM_THREAD_DEFER, SCM_THREAD_ALLOW, SCM_THREAD_REDEFER,
6416 SCM_THREAD_ALLOW_1, SCM_THREAD_ALLOW_2. Motivation: We don't want
6417 the main code in these macros duplicated and spread over multiple
6418 files. Renamed SCM_THREADS_SWITCHING_CODE ->
6419 SCM_THREAD_SWITCHING_CODE.
6421 Tue Oct 29 14:55:40 1996 Marius Vollmer <mvo@zagadka.ping.de>
6423 * snarf.h: New file.
6424 * guile-snarf.sh: New file.
6425 * Makefile.in (inner_h_files): Added snarf.h
6426 (ancillary, install, uninstall, distclean): Added actions for
6428 (.c.x): Use guile-snarf.
6429 (guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
6430 (gen_c_files): Note that these depend on guile-snarf.
6431 * _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
6432 now in "snarf.h". Added #include "snarf.h" to get them.
6433 * libguile.h: Added #include "snarf.h".
6434 (Patches applied and tweaked by Jim Blandy.)
6436 Tue Oct 29 13:21:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6438 * socket.c: Use K&R style declaration for 'close'; the GNU coding
6439 standards suggest against providing prototypes for system
6440 functions. Thanks to Greg Troxel.
6442 Mon Oct 28 16:48:32 1996 Jim Blandy <jimb@floss.cyclic.com>
6444 * strports.c (scm_eval_0str): New function.
6445 #include "read.h", to get prototype for scm_read.
6446 * Makefile.in (strports.o): Update dependencies.
6447 * strports.h: New prototype.
6449 * numbers.c (scm_integer_p): Renamed from scm_int_p; change its
6450 scheme name from "int?" to "integer?". It seems to do the job.
6451 * numbers.h: Rename prototype too.
6452 * scmhob.h (intp): Change definition to refer to scm_integer_p. I
6455 * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
6456 scm_num_eq_p): Rename these according to R4RS conventions: call
6457 them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
6458 to making libguile R4RS compliant without ice-9...
6460 * load.c (scm_sys_search_load_path): Search for files under all
6461 extensions listed in the %load-extensions variable. If FILENAME
6462 is absolute, return it unchanged, without searching the load path.
6463 (scm_loc_load_extensions): New variable, pointing to
6464 %load-extensions' value cell.
6465 (scm_init_load): Initialize it, and the value it points to.
6466 (scm_primitive_load_path): Improve error reporting.
6468 * load.c (scm_loc_load_hook): New variable, pointing to value cell
6469 of new Scheme variable %load-hook.
6470 (scm_primitive_load): Apply %load-hook to filename.
6472 Mon Oct 28 06:28:28 1996 Gary Houston <ghouston@actrix.gen.nz>
6474 * configure.in: add tests for figuring out whether buffered data
6475 is available in a FILE structure, which is needed by char-ready.
6477 * acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
6480 * simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
6481 exceptions using misc_error instead of syserror. It seems a bit
6482 odd to throw an exception if a string can't be found in the
6483 environment, but it's consistent with open-file, stat etc.
6484 (simpos.h): remove sys_ from getenv.
6486 * posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
6487 occurs, throw an error instead of returning errno. Return value
6489 (numerous in posix.c and posix.h): removed superfluous sys_ from names.
6491 Sun Oct 27 01:22:04 1996 Gary Houston <ghouston@actrix.gen.nz>
6493 * filesys.c (scm_stat2scm): derive file type and permissions from
6494 the stat mode and append them to the returned vector.
6495 There isn't much overhead in doing this and it avoids the need to
6496 work with S_IRUSR et al. in Scheme.
6497 Define symbols scm_sym_regular etc.
6498 (scm_init_filesys): don't intern S_IRUSR etc.
6500 * load.c: change s_try_load and s_try_load_path to s_primitive_load
6501 and s_primitive_load_path.
6503 * eval.c, load.c, error.c (scm_wta): use scm_misc_error.
6505 * error.h: don't declare error symbols. prototype for scm_misc_error.
6507 * stackchk.c (scm_stack_overflow_key): defined here instead of in
6510 * error.c: use SCM_SYMBOL to set up error keys.
6511 scm_misc_error: new procedure.
6513 Fri Oct 25 01:56:30 1996 Jim Blandy <jimb@floss.cyclic.com>
6515 * read.c (scm_lreadr): Recognize SCSH-style block comments; text
6516 between `#!' and `!#' is ignored.
6517 (skip_scsh_block_comment): New function.
6519 * feature.c (scm_set_program_arguments): New argument, FIRST.
6520 * feature.h: Update prototype.
6521 * init.c (scm_boot_guile_1): Pass new argument to
6522 scm_set_program_arguments.
6524 Tue Oct 22 20:54:42 1996 Jim Blandy <jimb@floss.cyclic.com>
6526 * init.c (scm_start_stack): Don't initialize scm_progargs here.
6527 (scm_boot_guile): Call scm_set_program_arguments here, later than
6528 the old initialization.
6530 * init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
6531 initialization procedure.
6532 - Delete in, out, err arguments; there are other perfectly good
6533 ways to override these when desired.
6534 - Delete result argument; this function shouldn't ever return.
6535 - Rename init_func argument to main_func, for less confusion.
6536 - Delete boot_cmd argument; main_func is more general.
6537 -Add 'closure' argument, to help people pass data to main_func
6538 without resorting to global variables.
6539 - Abort if reentered; don't bother returning an error code.
6540 - Call scm_init_standard_ports to set up the default/current
6541 standard ports; no need to pass them to scm_start_stack.
6542 - Remove code to evaluate the boot_cmd, and start the repl; let
6543 the user do something like that in main_func if they want.
6544 - Remove code to package up a return value; main_func can do any
6546 - Call exit (0), instead of returning.
6547 (scm_start_stack): Don't initialize the I/O ports here; that's
6548 weird. Delete in, out, err arguments. Move guts to
6549 scm_init_standard_ports, scm_stdio_to_port.
6550 (scm_init_standard_ports): New function, to set up current and
6551 default standard ports.
6552 (scm_start_stack, scm_restart_stack): Make these static.
6553 * init.h (scm_boot_guile): Adjust declaration.
6554 (scm_start_stack, scm_restart_stack): Remove externally
6555 visible declarations for these.
6556 (enum scm_boot_status): Removed; now scm_boot_guile never returns.
6558 * fports.c (scm_stdio_to_port): New function. Its guts used to be
6559 written out several times in scm_start_stack.
6560 * fports.h: New declaration for the above.
6562 * feature.c (scm_set_program_arguments): New function.
6563 * feature.h: New declaration for the above.
6565 * ports.c: Formatting tweak.
6567 Sun Oct 20 03:29:32 1996 Mikael Djurfeldt <mdj@kenneth>
6569 * pairs.h, eval.c, eval.h, feature.c, gc.c, list.c, load.c,
6570 ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
6571 for obtaining the address of a car or cdr field. Motivation:
6572 &SCM_CXR make assumptions about the internal structure of the
6575 * eval.h, eval.c: Added new selector SCM_GLOC_VAL_LOC.
6576 Motivation: see SCM_CXRLOC.
6578 * pairs.h, eval.c, gc.c, init.c, ioext.c, ports.c, ports.h,
6579 srcprop.h, tags.h, throw.c, unif.c: Added new selectors
6580 SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
6581 Motivation: Safer use. Some other macros are defined in terms of
6582 these operations. If these are defined using the SCM_SETCXR
6583 (<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
6584 to inefficiency and an <e1> with side-effects could potentially
6585 break. Also, these particular operations are heavily utilized in
6586 the garbage collector. In unoptimized code there will be a
6589 * alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
6590 eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
6591 ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,
6592 pairs.c, pairs.h, ports.c, ports.h, posix.c, procprop.c, procs.c,
6593 procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
6594 strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
6595 vports.c: Cleaned up use of pairs: Don't make any special
6596 assumptions about the internal structure of selectors and
6597 mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
6598 SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
6599 (Among other things, this change makes it easier to build Guile
6600 with certain compilers which have problems with casted lvalues.)
6602 Fri Oct 18 01:11:56 1996 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
6604 * stacks.c: Improve selection of relevant stack frames when making
6605 a stack object. Introduce one level of indirection in the stack
6606 object to make it possible to "narrow" to a certain region of the
6607 stack. This facilitates making use of more clever algorithms (not
6608 implemented) for selecting relevant frames and gives a cleaner
6609 design since selection of frames can be done independently of
6610 extraction of frames from the real stack.
6611 (scm_stack_id): Also take #t as argument which means look at
6614 * stacks.h: In struct scm_stack: Turn field frames into a pointer.
6615 Turn n_tail into an integer directly representing current number
6616 of frames in stack. Add field tail.
6618 * ports.c (scm_port_line_x, scm_port_column_x): New mutators.
6620 * debug.c (scm_make_memoized): Made it available at scheme level.
6621 (scm_unmemoize, scm_memoized_environment): Bugfix: Check for
6622 SCM_NIMP before applying heavier predicates in argument checking.
6623 (scm_local_eval): Also take memoized object as argument.
6625 * backtrace.c (scm_display_error): Just a safety measure: Stacks
6626 aren't created with zero length, but should such a strange
6627 creature suddenly turn up...
6629 Wed Oct 16 11:08:41 1996 Marius Vollmer <mvo@zagadka.ping.de>
6631 * hashtab.h (scm_hashx_remove_x): Renamed `delete' parameter to
6632 `del', for the sake of C++ compilers. (Patch applied by JimB.)
6634 Tue Oct 15 17:06:13 1996 Jim Blandy <jimb@floss.cyclic.com>
6636 * variable.c (scm_make_variable): Make the name hint optional, as
6638 (anonymous_variable_sym): Renamed from variable_sym. All uses
6641 * load.c (scm_primitive_load, scm_primitive_load_path): Renamed
6642 from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
6643 of scm_primitive_load_path was also changed to
6644 "primitive-load-path", from "%try-load-path". Callers changed.
6645 We'd like to respect the convention that a function named
6646 "try-mumble" should behave just like the function called "mumble",
6647 but return #f instead of signalling some error.
6648 * load.h: Rename prototypes.
6650 Tue Oct 15 05:34:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6652 * print.c (make_print_state, grow_print_state), print.h: Modified
6653 the print state representation: Don't use a tail array for
6654 recording of circular references. Resizing of the print state
6655 structure invalidates the print state pointer. To avoid passing
6656 around an indirect print state reference to all printing
6657 functions, we instead let the print state reference a resizable
6660 Mon Oct 14 19:25:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
6662 * alist.c (scm_sloppy_assq, scm_sloppy_assv, scm_sloppy_assoc):
6663 Don't crash when passed an improper list terminated by a
6664 non-immediate value.
6666 Mon Oct 14 19:08:33 1996 Jim Blandy <jimb@floss.cyclic.com>
6668 Allocate data for structures on an eight-byte boundary, as
6669 required by the tagging system.
6670 * struct.c (alloc_struct): New function.
6671 (scm_make_struct, scm_make_vtable_vtable): Call it.
6672 * struct.h (scm_struct_n_extra_words): Bump to 3.
6673 (scm_struct_i_ptr): New "field".
6674 * gc.c (scm_gc_sweep): When we need to free the data, use the
6675 information stored by alloc_struct to find the beginning of the
6676 block allocated to the structure, so we can free it.
6678 Mon Oct 14 17:07:55 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6680 * init.c (scm_boot_guile_1): Moved scm_init_struct in front of
6683 * debug.h (SCM_VOIDFRAME, SCM_VOIDFRAMEP): New macros.
6684 (scm_debug_info): New member: id.
6686 * stacks.c: Stacks are now represented as structs; Stacks have an
6687 id given to them by `start-stack'.
6688 (scm_last_stack_frame): Added predicates `stack?' and `frame?'.
6690 * stacks.h: Added declarations of scm_stack_p and scm_frame_p;
6691 Changed stack representation.
6693 * debug.c (scm_procedure_name): Try procedure property `name' for
6694 compiled closures aswell.
6696 * gc.c (scm_init_storage): Initialize scm_stand_in_procs to SCM_EOL.
6698 * eval.c: scm_i_name moved to gsubr.c
6699 (scm_m_define): Record names of all kinds of procedure
6700 objects. (Earlier, only closures were recorded.)
6702 * procprop.h: Added declaration of scm_i_name.
6704 * gsubr.c: Added global scm_i_name. Added #include "procprop.h".
6705 (scm_make_gsubr): Record names of compiled closures.
6707 Mon Oct 14 04:21:51 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6709 * debug.c, debug.h: Removed obsolete code.
6711 * continuations.c, continuations.h, debug.c, gc.c, init.c, root.c,
6712 stacks.c: Renamed regs --> scm_contregs.
6714 * print.c (scm_free_print_state): Cleanup print state before
6715 returning it to pool. It is better to do it here than in
6716 scm_prin1 since scm_prin1 is called often.
6718 * srcprop.c (scm_source_properties, scm_set_source_properties_x,
6719 s_set_source_property_x): Check that first argument is a pair or a
6722 * srcprop.c, srcprop.h: Made scm_i_filename, scm_i_copy,
6723 scm_i_line, scm_i_column and scm_i_breakpoint global.
6725 * init.c: Added #include "backtrace.h" and #include "stacks.h".
6726 (scm_boot_guile_1): Added calls to scm_init_backtrace and
6729 * debug.h: Added debug object smob declaration and macro
6732 * configure.in: Build with backtrace.o and stacks.o if debug
6735 * Makefile.in: Added entries for new files: backtrace.c,
6736 backtrace.h, stacks.c and stacks.h.
6738 * symbols.c (scm_sym2ovcell): Fixed documentation.
6740 * _scm.h (min, max): Added.
6742 * async.c: Moved `min' macro to _scm.h.
6744 * debug.h: New debug options SCM_BACKTRACE_MAXDEPTH and
6745 SCM_BACKTRACE_INDENT.
6747 * eval.c: Added new debug options `maxdepth' and `indent'.
6749 * print.c (make_print_state): Bugfix: Initialize pstate->ceiling.
6751 * print.h: Added selector SCM_PRINT_STATE.
6753 * print.c: New functions: scm_make_print_state,
6754 scm_free_print_state.
6756 * print.h: Added declarations for scm_make_print_state,
6757 scm_free_print_state.
6759 * debug.c (scm_m_start_stack): New acro.
6761 * debug.h: Small cleanup.
6763 * init.c (scm_boot_guile_1): Moved scm_init_debug below
6766 Sun Oct 13 20:14:53 1996 Jim Blandy <jimb@totoro.cyclic.com>

6786 unif.h, variable.c, variable.h, vectors.c, vectors.h, version.c,

6788 declare functions with prototypes. (Patch thanks to Marius
6791 More prototype-related changes from Marius Vollmer:
6792 * gdb_interface.h: Wrapped header file in #ifdef/#endif
6793 * gscm.h (gscm_run_scm): Added prototype for `initfn' paramter.
6794 * ports.h (ptobfuns): Added prototypes. This means some casting in
6796 * fports.c: Added casts for initializations, since the functions
6797 are defined to take FILE * as their stream argument, not SCM.
6798 * fdsocket.c, fdsocket.h: Made `init_addr_buffer' static.
6799 * genio.c (scm_gen_puts): Changed `unsigned char *str_data' parameter
6800 to `char *str_data' to conform to prototype.
6802 Sat Oct 12 21:49:29 1996 Gary Houston <ghouston@actrix.gen.nz>
6804 * error.c, eval.c, load.c, stackchk.c: use scm_error not lgh_error.
6806 * __scm.h (lgh_error): removed, lgh shouldn't be in libguile.
6808 * stime.c, stime.h: use SCM_P method.
6810 Sat Oct 12 16:16:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6812 * eval.c (scm_nconc2last): Don't accept an empty list; apply must
6813 be given at least two arguments. Insist that lst's last element
6814 be a list, but don't make any requirements of its predecessors.
6816 Fri Oct 11 03:58:25 1996 Jim Blandy <jimb@floss.cyclic.com>
6818 * eval.c (scm_nconc2last): Revert last change; there seems to be
6819 other stuff going on here.
6821 Fri Oct 11 02:43:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
6823 * eval.c (scm_nconc2last): Make sure that each element of lst
6824 (which is a list of argument lists, except for the tail) is a
6825 proper list, i.e., finite and terminated by '().
6827 Thu Oct 10 21:09:13 1996 Jim Blandy <jimb@totoro.cyclic.com>
6829 * unif.c (scm_ra_set_contp): Localize `inc' declaration.
6832 * struct.c (scm_make_struct, scm_make_vtable_vtable): Use the
6833 symbolic name for the tag, scm_tc3_cons_gloc, instead of just
6836 * vectors.c (scm_make_vector): Fill vectors with the undefined
6837 value, to help make Guile Scheme code more portable to other
6840 * symbols.c (scm_intern_obarray_soft, scm_sysintern): Doc fixes.
6841 * symbols.h, tags.h: Doc fixes.
6843 Wed Oct 9 19:39:29 1996 Jim Blandy <jimb@floss.cyclic.com>
6845 * async.c (scm_take_signal): Doc fixes.
6847 Mon Oct 7 22:30:34 1996 Jim Blandy <jimb@totoro.cyclic.com>
6849 * numbers.c (scm_divbigint): When the remainder is zero, we don't
6850 want to subtract it from the modulus; we just want to leave it
6853 Mon Oct 7 00:14:17 1996 Mikael Djurfeldt <mdj@kenneth>
6855 * init.c (scm_boot_guile_1): Bugfix: i --> base in argument to
6858 * throw.h (scm_catch_apply): Removed the `lazyp' argument.
6860 * throw.c (scm_catch_apply): Finished implementation of
6863 Sun Oct 6 05:26:05 1996 Gary Houston <ghouston@actrix.gen.nz>
6865 * filesys.c (scm_sys_select): move SCM_ALLOW_INTS past the sreturn
6867 (scm_init_filesys): set "i/o-extensions" feature.
6870 Sat Oct 5 12:22:00 1996 Jim Blandy <jimb@floss.cyclic.com>
6872 * Makefile.in (root.o): Correct dependencies.
6874 Sat Oct 5 18:40:42 1996 Mikael Djurfeldt <mdj@kenneth>
6876 * Makefile.in: Added dependency entry for root.o.
6878 * continuations.c, debug.[ch], eval.c, gscm.c init.c, root.c,
6879 throw.c: Renamed last_debug_info_frame -> scm_last_debug_frame.
6881 * init.c (scm_start_stack): Set initial root continuation number
6884 * procs.c: New function: scm_thunk_p.
6886 * procs.h: Added declarations of scm_thunk_p.
6888 * root.c: Renamed `call-with-new-root' -->
6889 `call-with-dynamic-root'.
6890 (cwdr): Removed allocation of new root state. This should be done
6891 separately by use of scm_make_root.
6892 (scm_apply_with_dynamic_root): New function: Does what it
6893 sounds like. Needed when spawning threads.
6895 * root.h: Added member last_debug_frame to root state.
6896 Added #include "libguile/debug.h"
6898 * throw.c: Renamed scm_catch --> scm_catch_apply and added more
6899 arguments. The motivation is that code in root.c needs catch
6900 functionality, and we want to avoid code duplication.
6901 New functions: scm_catch, scm_lazy_catch. These are wrappers for
6902 scm_catch_apply. scm_lazy_catch is intended to introduce catch
6903 handlers that run without popping the stack into the dynwind
6906 * throw.h: Added prototypes for scm_catch_apply and
6909 Thu Oct 3 11:12:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6911 * root.h (scm_root, scm_set_root): Decouple thread support details
6912 by introducing the selector SCM_THREAD_LOCAL_DATA and the mutator
6913 SCM_SET_THREAD_LOCAL_DATA.
6915 * print.c (scm_iprlist): Bugfix: Added SCM_ECONSP tests in hare
6916 and tortoise scanning loop.
6918 Thu Oct 3 00:04:53 1996 Jim Blandy <jimb@totoro.cyclic.com>
6920 * Makefile.in: Rebuild dependencies.
6922 * libguile.h: #include "libguile/print.h" before "smob.h", since
6923 the latter uses the print_state structure.
6925 * throw.c (scm_ithrow): Use the correct variable when checking to
6926 see if a given element of scm_dynwinds is a valid catch.
6928 * throw.c (scm_ithrow): If scm_dynwinds has invalid list
6929 structure, abort; don't just silently ignore the garbage.
6931 * _scm.h: #include "print.h" here, since it seems to be used just
6933 * eval.c, gdbint.c, genio.h, numbers.h, smob.h, srcprop.c,
6934 strports.c, unif.h: Don't #include "print.h".
6936 Tue Oct 1 05:15:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6938 * feature.h (scm_loc_features): Removed external declaration.
6939 (Bug fix suggested by Petr Adamek <adamek@mit.edu>.)
6941 Tue Oct 1 00:00:10 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
6943 * feature.c (scm_init_feature): Added threads feature (needs to be
6944 initialized here, since features doesn't exist when
6945 scm_init_threads is called).
6947 * libguile.h: Added #include "libguile/../threads/threads.h".
6948 (This is a kludge to get thread support working. This should be
6951 * configure.in, acconfig.h: Added flags for thread support.
6953 * scmsigs.c: Define `signal' to be `pthread_signal' if using
6956 * gc.c (scm_igc): Added SCM_THREAD_CRITICAL_SECTION_START and
6957 SCM_THREAD_CRITICAL_SECTION_END. Moved marking of root data to
6960 * _scm.h: Added conditional #include "threads.h"
6962 * __scm.h (SCM_ASYNC_TICK): Added call to macro
6963 SCM_THREADS_SWITCHING_CODE.
6965 * init.c (scm_start_stack): Call `scm_make_root' to dynamically
6966 allocate the basic dynamic root object.
6967 (scm_boot_guile): Added call to scm_init_root.
6969 * root.c, root.h: Added root smob.
6970 (cwdr, scm_call_with_new_root, scm_dynamic_root, scm_app_wdr): New
6971 functions: Implements dynamic roots mostly according to spec in
6972 SCM manual. Main difference is that the second argument is a
6973 throw handler rather than an error "thunk".
6975 * root.h: Added declaration of scm_init_root.
6977 * root.c: Added #include "genio.h", #include "smob.h", #include
6978 "pairs.h", #include "throw.h", #include "dynwind.h", #include
6980 (scm_init_root): Added #include "root.x".
6982 * throw.c: Added #include "stackchk.h"
6983 (scm_catch): Changed SCM_DEFER_INTS --> SCM_REDEFER_INTS and
6984 SCM_ALLOW_INTS --> SCM_REALLOW_INTS. This is so that scm_catch
6985 can be used in scm_call_with_new_root; Added reenabling of stack
6986 checking when catching a throw.
6988 Mon Sep 30 21:48:11 1996 Jim Blandy <jimb@totoro.cyclic.com>
6990 * list.c, list.h: Use SCM_P instead of CPP hair. Doc fixes.
6992 * list.c (scm_member, scm_memv, scm_memq): Return #f if a matching
6993 element is not found, as per R4RS.
6995 Sat Sep 28 18:13:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
6997 * list.c: Doc fixes throughout.
6999 Sat Sep 28 02:07:43 1996 Gary Houston <ghouston@actrix.gen.nz>
7001 * strings.c, strings.h: (scm_makfrom0str, scm_makefrom0str_opt:
7002 declare the char * to be const. Avoids a warning in rgx.c.
7004 * ports.h: spelling fix.
7006 * filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
7009 * load.c (scm_sys_try_load_path): throw an error if file not found
7010 (like it says it in NEWS).
7012 Fri Sep 27 18:27:01 1996 Jim Blandy <jimb@totoro.cyclic.com>
7014 * symbols.c (scm_intern_obarray_soft): Initialize the new symbol's
7015 PROPS slot to '(), not #f; it's an empty alist.
7017 * throw.h, throw.c: Use SCM_P instead of #if hair.
7019 Remove special support for uncaught throws; see throw.c for
7021 * throw.c (uncaught_throw): New function.
7022 (scm_ithrow): Call uncaught_throw if we don't find a throw
7023 target; don't mess with scm_bad_throw_vcell.
7024 (scm_bad_throw_vcell): Variable deleted.
7025 (scm_init_throw): Don't initialize it.
7027 * throw.c (scm_ithrow): Don't let outer key matches shadow inner
7030 Wed Sep 25 04:35:50 1996 Jim Blandy <jimb@totoro.cyclic.com>
7032 * numbers.c (scm_istr2int): If the number is short (as most
7033 numbers are), just call scm_small_istr2int to deal with it.
7034 (scm_small_istr2int): New function, created by un-#ifdefing the
7035 non-bignum version of scm_istr2int and renaming it.
7037 Tue Sep 24 06:48:38 1996 Gary Houston <ghouston@actrix.gen.nz>
7039 * load.c (scm_sys_try_load): don't check whether value returned
7040 by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
7041 Change the Scheme name from %try-load to primitive-load.
7043 * error.c (scm_error): convert a NULL message to SCM_BOOL_F.
7044 Can avoid passing a message, allowing it to be derived in the
7045 error handler (e.g., if we want to throw to the key both from
7048 Mon Sep 23 00:42:15 1996 Mikael Djurfeldt <mdj@kenneth>
7050 * print.c (scm_iprin1, scm_prin1, scm_iprlist): Circular
7051 references now have a new appearance which is more compact and
7052 also gives a clue about what the target of the reference is.
7053 By setting parameters in the print state, more fancy printing can
7054 be achieved. This is used by the (not yet commited) backtrace
7057 Sun Sep 22 17:10:06 1996 Mikael Djurfeldt <mdj@kenneth>
7059 * eval.c, numbers.h, unif.h, smob.h, srcprop.c: Added #include
7062 * print.c: Added #include "struct.h". Removed function
7065 * print.h: Modified prototypes for scm_iprlist, scm_prin1 and
7066 scm_iprin1. Removed prototype for scm_prlist.
7068 * arbiters.c (prinarb),
7069 async.c (print_async),
7070 debug.c (prindebugobj, prinmemoized),
7071 eval.c (prinprom, prinmacro),
7072 filesys.c (scm_fd_print, scm_dir_print),
7074 mallocs.c (prinmalloc),
7075 numbers.c, numbers.h (scm_floprint, scm_bigprint),
7076 smob.h (scm_smobfuns),
7077 srcprop.c (prinsrcprops),
7079 unif.c, unif.h (scm_raprin1, rapr1),
7080 variable.c (prin_var): Changed argument `int writing' to
7081 `scm_print_state *pstate'.
7083 * init.c (scm_boot_guile): Moved scm_init_struct upwards so
7084 that it will be called before scm_init_print.
7086 * print.c (scm_prin1): Print states are now allocated when calling
7087 scm_prin1 and then passed around to all printing functions as an
7088 argument. A cache `print_state_pool' enables reuse of print
7090 (scm_make_print_state): New function.
7091 (scm_iprin1): Adaption to print states.
7092 (scm_iprlist): An initial "hare and tortoise" scan brings down
7093 time complexity to O (depth * N). (Better time complexity will be
7094 achieved when the printing code is completely rewritten.)
7096 Fri Sep 20 22:01:36 1996 Jim Blandy <jimb@totoro.cyclic.com>
7098 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): Use AC_CACHE_CHECK instead of
7099 AC_CACHE_VAL; #define UTIMBUF_NEEDS_POSIX outside AC_CACHE_VAL, so
7100 it gets done whether or not the cache variable has a value.
7102 Thu Sep 19 17:06:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7104 Distinguish #f and ().
7105 * __scm.h: #undef SICP.
7106 * pairs.h (SCM_EOL): Delete this definition, equating it with
7108 * tags.h (SCM_EOL): Give it a new definition here; I think I found
7109 the value it used to have. Doc fixes, too.
7111 Thu Sep 19 15:33:51 1996 Mikael Djurfeldt <mdj@kenneth>
7113 * struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,
7114 scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom
7115 Lord's implementation of structs, allowing for tail arrays as
7116 described in the manual. Also fixed some bugs. (Both the interface
7117 and the implementation should be improved.)
7119 * read.c (scm_init_read): Removed #ifdef READER_EXTENSIONS
7121 * print.c, print.h: Closures now print like #<procedure foo (x)>.
7122 People who whish to see the source can do `(print-enable 'source)'.
7123 Removed #ifdef DEBUG_EXTENSIONS.
7125 Thu Sep 19 00:00:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7127 * filesys.c (scsm_sys_stat): don't SIGSEGV if argument is an
7128 integer (assuming for now accepting an integer is a good thing).
7130 * error.c, fports.c: replace use of %S in lgh_error args with %s.
7131 %S will be used instead for write'ing arguments.
7133 * unif.c (scm_transpose_array): change arguments in the SCM_WNA
7134 asserts. fix a few other asserts.
7135 (scm_aind, scm_enclose_array, scm_array_in_bounds_p,
7136 scm_uniform_vector_ref, scm_array_set_x,
7137 scm_dimensions_to_unform_array): change args in
7138 SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
7139 strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
7140 scm_substring_fill_x): likewise.
7141 gsubr.c (scm_gsubr_apply): likewise.
7142 eval.c (SCM_APPLY): likewise.
7144 * eval.c (4 places): replace scm_everr with lgh_error or
7147 * error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
7148 scm_memory_error): new procedures.
7149 scm_everr: deleted. can use scm_wta, dropping first two args.
7150 scm_error: convert NULL subr to SCM_BOOL_F.
7152 * __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
7155 * stackchk.c (scm_report_stack_overflow): use lgh_error instead
7158 * error.c, error.h: new error keys: scm_arg_type_key,
7159 scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
7161 scm_wta: reimplement using lgh_error instead of scm_everr.
7163 Wed Sep 18 17:13:35 1996 Mikael Djurfeldt <mdj@kenneth>
7165 * gdbint.c: scm_lread now has one more argument.
7167 * ports.c, ports.h: Name change: scm_\(line\|column\)_number -->
7168 scm_port_\1; Added mutator scm_set_port_filename_x (used when
7169 loading source from non-file ports, which, e. g., happens when
7170 using the Emacs interface).
7172 * fports.c (scm_open_file): Don't call scm_makfrom0str on a scheme
7175 * read.c: Added code for recording of positions of source code
7176 expressions; New functions: recsexpr, scm_lreadrecparen;
7177 _scm_make_srcprops --> scm_make_srcprops
7178 (scm_flush_ws): Removed updating of positions counters. This work
7179 is already done by scm_gen_getc
7181 * read.h: Added prototype for scm_lreadrecparen
7183 * print.c: Added #include "alist.h"
7185 * eval.c: Added #include "hash.h"
7187 * eq.c: Added #include "ramap.h"
7189 * options.c: Documentation fixes.
7191 * srcprop.c (scm_finish_srcprop): Bugfix: update ptr.
7192 (scm_init_srcprop): Adjusted size of initial source-whash. Name
7193 changes: tc16_srcprops --> scm_tc16_srcprops, _scm_make_srcprops
7194 --> scm_make_srcprops
7196 * srcprop.h: Name changes: tc16_srcprops --> scm_tc16_srcprops,
7197 _scm_make_srcprops --> scm_make_srcprops; Remove one layer of
7198 function calls in the definition of the whash access macros.
7200 Tue Sep 17 11:33:16 1996 Lee Iverson <leei@Canada.AI.SRI.COM>
7202 * init.c (scm_boot_guile): Add level of indirection to
7203 scm_boot_guile_1() to ensure that stack base pointer is properly
7204 initialized. There was no guarantee that variable i was the
7205 highest/lowest variable on stack (i.e. the call frame of
7206 scm_boot_guile was not completely protected from gc).
7208 Tue Sep 17 01:40:56 1996 Gary Houston <ghouston@actrix.gen.nz>
7210 * ports.h (scm_port_table): put back file_name, it will be used to
7211 support debugging. Undo related changes in fports.c, ioext.c,
7214 Sun Sep 15 03:58:29 1996 Gary Houston <ghouston@actrix.gen.nz>
7216 * ports.h (scm_port_table): remove file_name member for now, it seems
7218 * fports.c (scm_open_file): don't set file_name in PTAB.
7219 (prinfport): don't use file_name in PTAB.
7220 * ioext.c (scm_sys_duplicate_port): don't set file_name in PTAB.
7221 * ports.c (scm_add_to_port_table): don't intialize file_name.
7222 (scm_port_file_name): remove for now.
7223 * gc.c (scm_gc_mark): don't mark PTAB file_name.
7225 * fports.h (scm_mkfile): prototype deleted.
7226 * fports.c (scm_mkfile): merged into scm_open_file to simplify.
7228 * debug.c, unif.c: use scm_out_of_range instead of
7229 wta for range errors (ASSERT still needs work).
7231 * error.c, error.h (scm_out_of_range): new procedure.
7233 * error.c, error.h (scm_out_of_range_key): new key.
7235 * posix.c (scm_sync): #else was missing.
7237 * error.c, error.h: append _key to names scm_num_overflow and
7240 * __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
7241 of consing an empty list.
7242 (SCM_SYSERROR etc.): move into error.c, make them procedures instead
7243 of macros, saves code and string space.
7244 error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
7245 fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
7246 lower case. Rename scm_syserror_m to scm_syserror_msg.
7247 error.h: prototypes for new procedures.
7249 Sat Sep 14 03:35:41 1996 Gary Houston <ghouston@actrix.gen.nz>
7251 * numbers.c: use SCM_NUM_OVERFLOW instead of scm_wta or ASSERT.
7253 * error.c, error.h: setup scm_num_overflow key.
7255 * __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
7256 Remove definition of SCM_OVSCM_FLOW.
7258 * fports.c (scm_open_file): use SCM_SYSERROR_M.
7260 * __scm.h: SCM_SYSERROR_M: new macro for system errors with an
7261 explicit message and args.
7263 * error.c, error.h, __scm.h: change system_error_sym to
7266 * error.c (system_error_sym): remove leading %% from the Scheme name
7269 * __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
7271 Fri Sep 13 12:58:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7273 * __scm.h, chars.c, debug.c, eval.c, eval.h, extchrs.c, extchrs.h,
7274 fdsocket.c, feature.c, mbstrings.c, mbstrings.h, numbers.c,
7275 numbers.h, print.c, scmhob.h, simpos.h, symbols.c, symbols.h,
7276 tags.h, throw.c, variable.h: Name cleanup. Lots of xxxSCM_yyy
7277 renamed. (These were introduced by unsupervised name
7280 Fri Sep 13 01:19:08 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7282 * print.c: Added code for detection of circular references during
7283 printing. (init_ref_stack, grow_ref_stack): New functions. Added
7284 a hook for printing of closures (accessible via print options).
7285 This leads to a split of calls to scm_iprin1 into two classes:
7286 elementary print operations (e. g. the code which prints a smob)
7287 still use scm_iprin1 while top level calls (like scm_display) use
7288 scm_prin1. scm_prin1 begins by clearing the data structure used
7289 to record reference information.
7291 * print.h: Added declarations of scm_prin1 and scm_prlist.
7293 * strports.c (scm_strprint_obj): scm_iprin1 --> scm_prin1
7295 * gscm.c (gscm_portprint_obj): scm_iprin1 --> scm_prin1
7297 * gscm.h (gscm_print_obj): scm_iprin1 --> scm_prin1
7299 * error.c (err_head): scm_iprin1 --> scm_prin1
7301 * debug.c: Adjusted header comment.
7305 Wed Sep 11 17:55:59 1996 Jim Blandy <jimb@totoro.cyclic.com>
7307 * strerror.c: Doc fix.
7309 Thu Sep 12 00:00:32 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7311 * gdbint.c (gdb_read): Now possible to run during GC.
7312 (unmark_port, remark_port): New functions.
7314 * symbols.h (SCM_SETLENGTH): Use SCM_SETCAR.
7316 * read.c (scm_grow_tok_buf): Use scm_vector_set_length_x instead
7317 of allocating a new string object. Also, increase size by
7318 the factor 2 instead of 1.5.
7320 Wed Sep 11 15:10:38 1996 Petr Adamek <jimb@floss.cyclic.com>
7322 * __scm.h (SCM_P): Corrected to run under traditional C.
7324 * _scm.h (SCM_PROC): Extraneous semicolon (outside functions)
7327 * async.c: Calls to scm_sysintern corrected.
7329 * async.h (scm_async_clock): Redundant declaration removed.
7331 * continuations.c (scm_dynthrow): Redundant declaration removed.
7333 * debug.c (scm_single_step, scm_memoized, scm_lookup_soft):
7334 Definition typos corrected.
7336 * debug.h: Missing declarations of functions in debug.c added
7339 * eval.h (scm_eval_args, scm_deval_args, scm_m_undefine):
7340 Missing declarations to functions in eval.c added.
7342 * filesys.c: Possibly uninitialized variable rv.
7344 * gc.h (scm_object_addr, scm_unhash_name): Missing
7345 declarations of functions defined in gc.c added.
7347 * genio.c: Possible typos str_data -> wstr_data. ???
7349 * genio.c: Possibly unintended shadowing of local variable
7350 `int c' (gotos out of scope of inner `c'). ???
7352 * init.c: Uninitialized `SCM last' may be used.
7354 * ioext.h: (scm_sys_isatty_p): Typo.
7356 * list.h (scm_list_head): Missing prototype for function in
7359 * numbers.c (scm_two_doubles): Changed from extern to static
7360 (is used only within numbers.c).
7362 * numbers.h: Repeated declarations removed.
7364 * ports.h (scm_close_all_ports_except): Declaration for the
7365 function defined in ports.c added.
7367 * posix.h: Missing declarations added.
7369 * procs.h (scm_make_subr_opt): Missing declaration added.
7371 * socket.h (scm_sys_gethost): Missing declaration added.
7373 * socket.h: Redundant declarations removed (they are in fdsocket.h).
7375 * srcprop.h (scm_set_source_property_x, scm_finish_srcprop):
7376 Missing declarations added.
7378 * stime.h (scm_get_internal_real_time): Repeated declarations removed.
7380 * struct.c: Uninitialized variable `SCM answer' may be used.
7382 * unif.c (l2ra): Declaration prototype.
7384 * unif.c (scm_array_equal_p): Dummy definition removed (it is
7385 defined in ramap.c).
7387 * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p):
7388 Redundant declarations removed (they are in ramap.h).
7390 * variable.h (scm_make_udvariable,
7391 scm_make_undefined_variable): Declaration corrected to
7392 correspond variable.c.
7394 * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x):
7395 Missing declarations added.
7397 Wed Sep 11 14:38:50 1996 Jim Blandy <jimb@floss.cyclic.com>
7399 * Makefile.in (distclean): Don't forget to delete fd.h.
7401 Tue Sep 10 14:01:46 1996 Jim Blandy <jimb@floss.cyclic.com>
7403 * fd.h.in, tags.h: Trivial cleanups.
7405 * marksweep.c, marksweep.h: Deleted; marksweep.c was empty, and
7406 marksweep.h just declared functions from gc.c.
7407 * gc.h, libguile.h: Don't #include "marksweep.h".
7408 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7409 marksweep.o, marksweep.h, marksweep.c, and marksweep.x. Other
7410 dependencies updated.
7412 * libguile.h: Don't #include "files.h"; it's been deleted.
7414 * files.c (scm_sys_delete_file): Moved to filesys.c.
7415 File is now empty; deleted.
7417 * filesys.c: scm_sys_delete_file is now here. Remove
7418 #if's; they seem to rely on remnants of an old portability
7419 regimen. If the problems come up again, solve them properly,
7420 using autoconf. Specifically: Don't test M_SYSV, and #define
7421 remove to be unlink if it's #defined; don't use remove just
7422 because HAVE_STDC_HEADERS is #defined.
7423 * filesys.h: Add declarations for scm_sys_delete_file.
7424 * Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
7425 files.o, files.h, files.c, and files.x.
7426 * init.c: Don't #include "files.h", and don't call scm_init_files.
7428 Use SCM_P instead of PROTO; the latter intrudes on the user's
7430 * params.h: Deleted; definition of SCM_P moved to...
7431 * __scm.h: ... here, where it replaces PROTO macro.
7432 * libguile.h, smob.h: Don't #include "params.h".
7433 * continuations.c, error.h, feature.h, gc.c, gc.h, init.h, load.h,
7434 smob.h: Fix prototypes accordingly.
7435 * Makefile.in: Update dependencies.
7436 (inner_h_files): Remove params.h.
7438 * gc.c: #include "gc.h"; every module should include its header,
7439 to let the compiler cross-check the declarations against the
7442 * eq.h, files.h, hashtab.h, load.h, mallocs.h, scmsigs.h,
7443 simpos.h: #include "libguile/__scm.h".
7445 Mon Sep 9 20:00:15 1996 Jim Blandy <jimb@floss.cyclic.com>
7447 * init.c: Don't forget to #include smob.h and init.h.
7448 * Makefile.in: Dependencies updated.
7450 * smob.h: Use PROTO instead of #if __STDC__.
7452 * continuations.c (scm_dynthrow): Use PROTO, not SCM_P.
7454 * __scm.h: Doc fixes.
7456 * __scm.h, libguile.h: Use "quotes" in the #includes, not
7457 <angles>; this allows `make depends' to work properly.
7459 * libguile.h: #include smob.h and pairs.h before the others; they
7460 define typedefs used by other headers.
7462 C files should #include only the header files they need, not
7463 libguile.h (which #includes all the header files); the pointless
7464 recompilation was wasting my time.
7465 * Makefile.in (all .o dependency lists): Regenerated.
7466 * libguile.h: Don't try to get a definition for size_t here...
7467 * __scm.h: Do it here.
7468 * _scm.h: Since this is the internal libguile header, put things
7469 here that all (or a majority) of the libguile files will want.
7470 Don't #include <libguile.h> here; that generates dependencies on
7471 way too much. Instead, get "__scm.h", "error.h", "pairs.h",
7472 "list.h", "gc.h", "gsubr.h", "procs.h", "numbers.h", "symbols.h",
7473 "boolean.h", "strings.h", "vectors.h", "root.h", "ports.h", and

7570 * weaks.c: Get "weaks.h".
7572 * stackchk.h: #include "libguile/debug.h",
7574 * print.h, read.h: #include "options.h", since everyone who uses
7575 either of these files will need that.
7577 * smob.h: #include "ports.h", "genio.h", and "print.h", since
7578 anyone who uses this file will need them to define the smob
7579 printing functions. Also, get markers.h, since people will need
7580 to #define the mark functions.
7582 * smob.h (scm_ptobfuns, SCM_PTOBNUM): Definitions moved...
7583 * ports.h: ... to here.
7585 * ports.h (scm_port_table_size): Explicitly give type as 'int';
7586 don't rely on archaic C default type rules.
7588 * fports.h: #include "libguile/ports.h", since you need that in
7589 order to parse this.
7591 * genio.h: #include "libguile/print.h", because you need that to
7592 parse this; don't bother #including "ports.h", since print.h gets
7595 * error.h: Don't #include "pairs.h"; _scm.h will do that now.
7597 * eval.h (scm_top_level_lookup_thunk_var): Remove declaration for
7598 this; it's now a reference to an element of *scm_root.
7600 * debug.h: Don't #include "options.h"; the compiler won't be able
7601 to find that once the headers are installed; instead, #include
7602 "libguile/options.h".
7603 * gc.h: Same, with marksweep.h.
7604 * mbstrings.h: Same, with symbols.h.
7605 * scmhob.h: Same, with _scm.h.
7606 * smob.h: Same, with params.h.
7608 * Makefile.in (depends): Don't nuke scmconfig.h and the generated
7609 C files; there's no need for this, and it forces recompilations
7612 Sat Sep 7 06:57:23 1996 Gary Houston <ghouston@actrix.gen.nz>
7614 * error.c (scm_error): declare scm_error_callback.
7616 * error.h: prototype for scm_error_callback.
7618 * __scm.h: define lgh_error.
7619 (SCM_SYSERROR): redefine using lgh_error.
7621 Thu Sep 5 22:40:06 1996 Gary Houston <ghouston@actrix.gen.nz>
7623 * error.c (scm_error): new procedure.
7625 * error.h: prototype for scm_error.
7627 * Makefile.in (install): install scmconfig.h from the current
7628 directory, not $(srcdir).
7630 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7632 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7633 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7634 feature.h, filesys.h, fports.h, gc.h, gdbint.h, genio.h, gsubr.h,
7635 hash.h, init.h, ioext.h, kw.h, list.h, markers.h, marksweep.h,
7636 mbstrings.h, numbers.h, objprop.h, options.h, pairs.h, ports.h,
7637 posix.h, print.h, procprop.h, procs.h, ramap.h, read.h, root.h,
7638 sequences.h, smob.h, socket.h, srcprop.h, stackchk.h, stime.h,
7639 strings.h, strop.h, strorder.h, strports.h, struct.h, symbols.h,
7640 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7641 vports.h, weaks.h: #include "libguile/__scm.h", not
7642 <libguile/__scm.h>. This allows 'gcc -MM' to determine which
7643 dependencies are within libguile properly.
7645 Thu Sep 5 11:38:07 1996 Jim Blandy <jimb@floss.cyclic.com>
7647 * Makefile.in (.c.x): Simplify; there's no need to run this rule
7648 when scmconfig.h doesn't exist.
7650 * load.c (scm_sys_try_load): Correct spelling.
7652 * feature.c (scm_loc_features): Make this static.
7654 * Makefile.in (libpath.h): Omit trailing slash from path. We
7655 shouldn't require it of users, so why put it here?
7657 Move code to initialize and search %load-path from ice-9 to C
7658 code, so we can use the load-path to find the ice-9 boot code;
7659 this makes it easier to run Guile without installing it. See
7660 corresponding changes in guile/Makefile.in.
7661 * feature.c: Move stuff concerned with the load path to load.c.
7662 (scm_compiled_library_path): Deleted.
7663 Don't #include libpath.h here.
7664 * feature.h: Don't mention scm_compiled_library_path.
7665 * load.c: #include "libpath.h" here, as well as <sys/types.h>,
7666 <sys/stat.h>, and <unistd.h> (if present).
7667 (R_OK): #define if the system hasn't deigned to.
7668 (scm_loc_load_path): New variable.
7669 (scm_init_load_path, scm_sys_search_load_path,
7670 scm_sys_try_load_path): New functions.
7671 (scm_init_load): Initialize scm_loc_load_path to point to the
7672 value cell of the Scheme %load-path variable.
7673 * load.h: Add declarations for scm_sys_search_load_path,
7674 scm_sys_try_load_path.
7675 * init.c: Call scm_init_load_path.
7676 * Makefile.in (feature.o, load.o): Dependencies updated.
7678 * load.c, load.h: Rewrite using PROTO macro.
7680 Thu Sep 5 01:54:33 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7682 * gc.c (scm_cellp): New function: C predicate to determine if an
7683 SCM value can be regarded as a pointer to a cell on the heap.
7685 * gc.h: Added declaration of scm_cellp.
7687 * gdb_interface.h: New file: The GDB interface header from the GDB
7690 * gdbint.c: New file: GDB interface.
7692 * gdbint.h: New file: GDB interface.
7694 * libguile.h: Added #include <libguile/gdbint.h>.
7696 * init.c (scm_boot_guile): Added scm_init_gdbint.
7698 * Makefile.in: Added gdb_interface.h, gdbint.[hc].
7699 Added -I.. to INCLUDE_CFLAGS (otherwise the include files won't be
7700 found if object files and source are kept separate).
7702 Wed Sep 4 14:35:02 1996 Jim Blandy <jimb@floss.cyclic.com>
7704 * feature.h, feature.c: Use PROTO macro, instead of #if __STDC__.
7706 Wed Sep 4 01:30:47 1996 Jim Blandy <jimb@totoro.cyclic.com>
7708 * configure.in: Don't substitute the values of TCL_SRC_DIR and
7709 TK_SRC_DIR; they're not relevant any more.
7711 * Makefile.in (CC): Don't list -Wall here; it's a GCC-specific flag.
7712 * configure.in: Instead, put it in CFLAGS here, iff we're using GCC.
7714 Wed Sep 4 00:55:49 1996 Jim Blandy <jimb@floss.cyclic.com>
7716 * PLUGIN/guile.config (xtra_cflags): Include .. in the header
7717 search path, so we can find the <libguile/MUMBLE.h> headers.
7719 * Makefile.in (ancillary): List aclocal.m4, for 'make dist'.
7721 * Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
7722 implicit in the .c.o rule.
7723 (.c.x): Don't mention ALL_CFLAGS here; its value is included in
7726 Put the library path in a header file, instead of passing it on
7727 the command line in every compilation.
7728 * Makefile.in (libpath.h): New target.
7729 (feature.o): Depend on libpath.h.
7730 (clean): Delete libpath.h.
7731 (ALL_CFLAGS): Don't use -DLIBRARY_PATH here. Instead ...
7732 * feature.c: ... #include "libpath.h" here.
7733 * .cvsignore: Ignore libpath.h.
7735 Don't install the unwashed masses of Guile header files in the
7736 main #include path; put most of them in a subdirectory called
7737 'libguile'. This avoids naming conflicts between Guile header
7738 files and system header files (of which there were a few).
7739 * Makefile.in (pkgincludedir): Deleted.
7740 (innerincludedir): New variable; this and $(includedir) are enough.
7741 (INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
7742 (installed_h_files): Divide this up. Now this variable lists
7743 those header files which should go into $(includedir) (i.e. appear
7744 directly in the #include path), and ...
7745 (inner_h_files): ... this new variable says which files appear in
7746 a subdirectory, and are referred to as <libguile/mumble.h>.
7747 (h_files): List them both.
7748 (install): Create innerincludedir, not pkgincludedir. Put
7749 the installed_h_files and inner_h_files in their proper places.
7750 (uninstall): Corresponding changes.
7751 * alist.h, append.h, arbiters.h, async.h, boolean.h, chars.h,
7752 continuations.h, debug.h, dynwind.h, error.h, eval.h, fdsocket.h,
7753 feature.h, fports.h, gc.h, genio.h, gsubr.h, hash.h, init.h,
7754 ioext.h, kw.h, libguile.h, list.h, markers.h, marksweep.h,
7755 mbstrings.h, numbers.h, options.h, pairs.h, ports.h, posix.h,

7759 tag.h, throw.h, unif.h, variable.h, vectors.h, version.h,
7760 vports.h, weaks.h: Find __scm.h in its new location.
7761 * __scm.h: Find scmconfig.h and tags.h in their new locations
7762 (they're both "inner" files).
7764 Tue Sep 3 20:27:35 1996 Jim Blandy <jimb@floss.cyclic.com>
7766 * Makefile.in (.c.x): Remove duplicate use of $(ALL_CFLAGS).
7768 Tue Sep 3 19:53:00 1996 Jim Blandy <jimb@totoro.cyclic.com>
7770 * posix.c: Doc fixes.
7772 Mon Sep 2 15:22:40 1996 Jim Blandy <jimb@totoro.cyclic.com>
7774 * socket.c: Don't include a prototype for inet_aton; just use a
7775 K&R style declaration, to avoid warnings but minimize the chance
7776 of conflicts with the system.
7778 On NextStep, <utime.h> doesn't define struct utime, unless we
7779 #define _POSIX_SOURCE before #including it.
7780 * aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
7781 * acconfig.h: New comment text for above CPP symbol.
7782 * configure.in: Call it.
7783 * posix.c: #define _POSIX_SOURCE if it seems necessary.
7785 * configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
7787 * posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
7788 testing for __EMX__.
7790 * posix.c: #include <libc.h>, if it exists.
7792 * posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
7793 don't even know if the latter exists.
7795 * posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
7796 s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
7797 s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
7799 * posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
7801 (scm_init_posix): Use them when initializing the Scheme constants
7804 Fri Aug 30 16:01:30 1996 Jim Blandy <jimb@floss.cyclic.com>
7806 * Makefile.in (libdir, includedir, bindir): Use the
7807 autoconf-supplied values, instead of deriving them ourselves.
7808 (pkgincludedir, datadir, pkgdatadir): New variables.
7809 (install, uninstall): Put the header files in a special
7810 subdirectory, not in the main search path.
7812 * Makefile.in (ALL_CFLAGS): Provide the proper value for
7813 LIBRARY_PATH --- use $(pkgdatadir) instead of $(libdir).
7815 * Makefile.in (IMPLPATH): Deleted; never used.
7817 * Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
7818 on the Tcl/Tk source any more.
7819 (INCLUDE_CFLAGS): Remove references to the above.
7821 * Makefile.in (version.o): Corrected dependencies.
7823 Thu Aug 29 23:06:19 1996 Thomas Morgan <tmorgan@gnu.ai.mit.edu>
7825 * libguile.h: #include "version.h"
7827 * init.c (scm_boot_guile): Call scm_init_version.
7828 * gscm.c (gscm_run_scm): Call scm_init_version.
7830 * configure.in (GUILE_MAJOR_VERSION, GUILE_MINOR_VERSION,
7831 GUILE_VERSION): AC_DEFINE these.
7832 (acconfig.h): #undef the above symbols.
7834 * Makefile.in (libobjs): Add version.o.
7835 (installed_h_files): Add version.h.
7836 (c_files): Add version.c.
7837 (gen_c_files): Add version.x.
7838 (version.o): New rule.
7839 (alist.o, append.o, appinit.o, arbiters.o, async.o, boolean.o,
7840 chars.o, continuations.o, dynwind.o, eq.o, error.o, eval.o,

7848 throw.o, unif.o, variable.o, vectors.o, version.o, vports.o,
7849 weaks.o): Add version.h to dependency lists.
7850 (markers.o): Remove duplicate rule.
7852 * version.h: New file.
7854 * version.c: New file.
7856 Thu Aug 29 15:21:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
7858 * symbols.c (scm_strhash): scm_downcase is now a function, not an
7859 array; use it appropriately. Since GCC is quite happy to
7860 subscript functions, it never warned us about this; we should use
7861 -Wpointer-arith in the future. I guess we never tested
7864 Wed Aug 28 18:52:22 1996 Jim Blandy <jimb@totoro.cyclic.com>
7866 * socket.c: Doc and copyright fixes.
7868 Sat Aug 24 05:29:19 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7870 * debug.c: Fixed and improved gdb support.
7872 Fri Aug 23 18:00:16 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7874 * socket.c: Added declaration of inet_aton to avoid compiler
7875 warning. (Hope this solution is correct.)
7877 * stime.c: Added declaration of ftime. (This is missing in
7880 Fri Aug 23 02:03:32 1996 Gary Houston <ghouston@actrix.gen.nz>
7882 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
7884 * Makefile.in (c_files): add strerror.c.
7886 * strerror.c: new file from Emacs' sysdep.c.
7887 maybe configure should also check for sys_errlist.
7889 * configure.in (AC_REPLACE_FUNCS): add strerror.
7891 Fri Aug 23 03:02:46 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7893 * debug.c (scm_init_debug): Added initialization for
7894 scm_evaluator_traps.
7896 * debug.h, debug.c: Various name changes.
7897 (Mostly prefixing with SCM_.) Renamed "debug-options" -->
7898 "debug-options-interface". See commentary in options.c.
7900 * options.h, options.c: Options now have documentation strings.
7901 Also added a long explanatory commentary.
7903 * eval.c, print.h, print.c, read.h, read.c: Modifications to
7906 * gscm.c, init.c, root.c, throw.c: Bug fixes:
7907 last_debug_info_frame is now updated in all cases.
7909 * __scm.h, stackchk.h, stackchk.c: Guile now performs stack
7912 Thu Aug 22 17:34:17 1996 Mikael Djurfeldt <mdj@woody.nada.kth.se>
7914 * __scm.h: SCM_STACK_LIMIT removed (now a run-time option).
7915 Added option STACK_CHECKING.
7917 Tue Aug 20 18:48:40 1996 Mikael Djurfeldt <djurfeldt@nada.kth.se>
7919 * Makefile.in: Added {debug,options,srcprop}.{h,c}
7921 * __scm.h: Removed symbols for debugging support.
7923 * acconfig.h: Added symbols for debugging support.
7925 * configure.in: Added user option for debugging support.
7926 --enable-debug will include the debugging code into libguile.a.
7928 * continuations.c (scm_make_cont): Enlarged the #if 0 around
7929 scm_relocate_chunk_to_heap.
7931 * debug.c: New file: low-level debugging support. It also
7932 includes support for debugging with gdb. (The extensions to gdb
7933 are written by Per Bothner at Cygnus.)
7935 * debug.h: New file: low-level debugging support.
7937 * eval.c: scm_m_set and SCM_IM_SET no longer supports multiple
7938 argument pairs. Extensive modifications to the debugging
7939 evaluator. Added "SECTION:" commentaries to clarify what happens
7940 when, during double compilation. Renamed EVALIMP --> EVALIM.
7941 Renamed EVAL --> XEVAL. Removed function evalcar. Defined
7942 evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
7943 the beginning of the file. New procedure: scm_unmemocopy.
7944 Added some global state variables needed by the debugging
7945 evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
7946 check_entry, check_apply, check_exit, debug_options and
7947 evaluator_traps. New acro: undefine.
7949 * eval.h: Renamed EVAL --> XEVAL.
7951 * gc.c (scm_init_storage): Renamed scm_make_weak_hash_table
7952 --> scm_make_weak_key_hash_table.
7954 * init.c (scm_restart_stack, scm_boot_guile): Added initialization
7955 of SCM_DFRAME. Added calls to scm_init_{debug,options,srcprop}.
7957 * libguile.h: Conditionally include debug.h
7959 * objprop.c (scm_object_properties, scm_set_object_properties_x):
7960 scm_object_properties shouldn't return handle. `handle' now gets
7961 initialized in scm_set_object_properties_x. scm_object_properties
7962 doesn't any longer create an entry in scm_object_whash.
7964 * options.c: New file: handling of run time options.
7966 * options.h: New file: handling of run time options.
7968 * posix.c (scm_getpgrp): Cast pointer to getpgrp.
7970 * print.c: New procedure: scm_print_options
7972 * print.h: Defines for print options.
7974 * read.c: New procedure: scm_read_options
7976 * read.h: Defines for reader options.
7978 * root.h: Added scm_source_whash among scm_sys_protects.
7980 * srcprop.c: New file: source properties.
7982 * srcprop.h: New file: source properties.
7984 * throw.c (jbsmob): Jump buffers are now correctly allocated.
7985 (Bug found by A. Green.)
7987 * weak.c: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
7989 * weak.h: Renamed scm_weak_hash_table --> scm_weak_key_hash_table.
7991 Thu Aug 15 02:05:14 1996 Jim Blandy <jimb@totoro.cyclic.com>
7993 * libguile.h: #include "objprop.h"; I guess this was forgotten.
7995 * init.c (scm_boot_guile): Don't call scm_init_rgx; it's a plugin,
7996 and should be called by the final client.
7998 Wed Aug 14 21:41:37 1996 Jim Blandy <jimb@totoro.cyclic.com>
8000 * gc.h: Use the PROTO macro when declaring functions.
8001 * gc.c: Use the PROTO macro when declaring static functions.
8002 Remove the CPP hair around function definitions.
8004 * gc.c (scm_init_storage): Initialize scm_asyncs.
8006 * libguile.h: #include "__scm.h" before testing the STDC_HEADERS
8007 preprocessor symbol; "__scm.h" is where it might get #defined.
8008 * __scm.h: Similar: #include <scmconfig.h> before testing
8011 * __scm.h: It's HAVE_LIMITS_H, not HAVE_LIMITSH.
8013 Fri Aug 9 11:09:28 1996 Jim Blandy <jimb@totoro.cyclic.com>
8015 * init.c (scm_boot_guile): Add init_func argument; call
8016 (*init_func) instead of calling scm_appinit; it's ucky to
8017 hard-code names for the user's procedures.
8018 * init.h (scm_boot_guile): Adjust declaration.
8020 * __scm.h (PROTO): New macro, for declaring functions with
8023 * init.h (scm_start_stack, scm_restart_stack): Use PROTO;
8024 eliminate all the __STDC__ conditionals.
8025 (scm_boot_guile): Add declaration.
8026 * init.c (scm_start_stack, scm_restart_stack, scm_boot_guile):
8027 Remove __STDC__ conditionals around function definitions; the
8028 declarations in init.h will provide the same information, more
8031 * __scm.h (SCM_SYSMISSING): When we don't have ENOSYS, don't
8032 complain about it in the error message; the error message is
8033 adequate without that note, and there's nothing the user can do
8036 Wed Aug 7 14:14:46 1996 Jim Blandy <jimb@totoro.cyclic.com>
8038 * Makefile.in (ancillary): Drop def.sed.
8040 * posix.c (scm_init_posix): Use numeric values, rather than
8041 CPP symbols, when defining the scheme values R_OK, W_OK, X_OK, and
8042 F_OK. The symbols aren't available on some systems, and I'm
8043 pretty sure their values are fixed by common widespread practice.
8044 * ioext.c (scm_init_ioext): Code here defined them too; remove it.
8046 More functions unavailable on some systems.
8047 * configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid,
8048 tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to
8050 * configure, scmconfig.h.in: Updated, using autoconf and autoheader.
8051 * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid,
8052 scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the
8053 bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a
8054 stub that signals an error as the #else.
8056 * Makefile.in (ancillary): Drop acconfig-1.5.h; add acconfig.h.
8058 Wed Aug 7 06:28:42 1996 Gary Houston <ghouston@actrix.gen.nz>
8060 * Fixes motivated by Petr Adamek <adamek@mit.edu>:
8062 * unif.c: include ramap.h.
8064 * read.c (endif): case_insensative_p renamed case_insensitive_p.
8066 * ramap.h: rename scm_array_copy prototypes to scm_array_copy_x.
8068 * ports.c: include sys/ioctl.h.
8070 * scmconfig.h.in: add HAVE_SYS_IOCTL_H.
8072 * configure.in: check for sys/ioctl.h.
8074 * ports.c: include <malloc.h> not "malloc.h".
8076 * mallocs.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8078 * fports.c: remove ttyname and tmpnam declarations.
8080 * posix.c: fewer ttyname declarations.
8082 * fports.c: include <string.h> not "string.h".
8084 * init.c, ioext.c: include string.h and unistd.h.
8086 * gc.c: include <malloc.h> not "malloc.h", likewise for unistd.h.
8088 * async.c, strings.h, strports.c, struct.c, symbols.c, feature.c,
8089 genio.c, simpos.c, vports.c: include string.h.
8091 * socket.c, fdsocket.c: include string.h only if HAVE_STRING_H.
8093 * fdsocket.c (getsockopt, setsockopt): change type of optlen from
8095 (scm_addr_buffer_size): change type from scm_sizet to int.
8096 (accept, getsockname, getpeername, recvfrom): change type of tmp_size
8097 from scm_sizet to int.
8099 * error.c: include unistd.h.
8101 * __scm.h: (SCM_SYSMISSING): another version in case ENOSYS isn't
8104 * Makefile.in: remove references to .hd, .cd suffix and __scm.hd.
8106 * __scm.hd, def.sed: deleted.
8108 Tue Aug 6 14:49:08 1996 Jim Blandy <jimb@totoro.cyclic.com>
8110 Changes for NeXT, suggested by Robert Brown.
8111 * configure.in: Call AC_TYPE_MODE_T.
8112 (AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
8113 NeXT. Put header file list in alphabetical order.
8114 * configure, scmconfig.h.in: Regenerated.
8115 * filesys.c [HAVE_LIBC_H]: #include <libc.h>.
8117 * filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
8120 * acconfig.h: New file, providing documentation for the CPP
8121 symbols defined in configure.in
8122 * acconfig-1.5.h: Removed; superceded by the above.
8124 Sat Aug 3 01:27:14 1996 Gary Houston <ghouston@actrix.gen.nz>
8126 * ioext.c (scm_sys_fdopen): fix the port-table assignment.
8128 * fports.c (scm_open_file): don't return #f, throw error.
8130 * ioext.c (fileno): renamed from %fileno.
8131 (soft-fileno): deleted.
8133 * ports.c (scm_port_revealed): don't need to check for -1 from
8135 (scm_set_port_revealed_x): return unspecified, not #f.
8137 * ioext.c (primitive-move->fdes): return #t or #f, not 1 or 0.
8139 * fdsocket.c: getsockopt, setsockopt: use HAVE_STRUCT_LINGER.
8141 * scmconfig.h.in: add HAVE_STRUCT_LINGER.
8143 * configure.in: check for struct linger, set HAVE_STRUCT_LINGER.
8145 Thu Aug 1 02:58:39 1996 Jim Blandy <jimb@totoro.cyclic.com>
8147 * filesys.c, posix.c: #include <sys/types.h> before <sys/stat.h>.
8148 This is necessary on Ultrix, and doesn't hurt portability.
8150 * Makefile.in (dist-dir): New target, implementing a new dist system.
8151 (installed_h_files): Put in alphabetical order.
8152 Remove duplicate entries for markers.h and unif.h.
8153 (c_files): Remove duplicate entries for markers.c.
8154 (ancillary): Renamed from anillery; all uses changed. Remove
8155 PLUGIN; it's a directory, and needs special treatment in dist-dir.
8156 Remove all the ../doc/* files; doc/Makefile.in handles that.
8158 * Makefile.in (libobjs): Remove duplicate entry for markers.o.
8160 * Makefile.in (.c.x): Compensate for Ultrix's broken Bourne shell:
8161 every if must have an else, or else the whole command has a
8162 non-zero exit code whenever the if's condition is false.
8164 Thu Aug 1 08:22:24 1996 Gary Houston <ghouston@actrix.gen.nz>
8166 * posix.c: include string.h.
8168 Wed Jul 31 23:43:05 1996 Gary Houston <ghouston@actrix.gen.nz>
8170 * numbers.c: rename %expt -> $expt, %atan2 -> $atan2, as it must
8173 * posix.c, ioext.c, socket.c, fdsocket.c, files.c, filesys.c, simpos.c:
8174 Remove leading % from scheme names.
8175 Do not return error values, call SCM_SYSERROR or similar.
8177 * __scm.h (SCM_SYSERROR, SCM_SYSMISSING): new macros.
8179 Wed Jun 12 00:28:31 1996 Tom Lord <lord@beehive>
8181 * struct.c (scm_init_struct): new file.
8183 Fri Jun 7 14:02:00 1996 Tom Lord <lord@beehive>
8185 * list.c (scm_list_tail): list-cdr-ref is the same as list-tail.
8186 (scm_list_head): added list-head for rapidly chopping argument
8187 lists off of longer lists (and similar).
8189 Tue Jun 4 09:40:33 1996 Tom Lord <lord@beehive>
8191 * objprop.c (scm_object_property): assq the cdr of the whash
8192 handle for obj, not the handle itself.
8194 Mon Jun 3 17:19:30 1996 Tom Lord <lord@beehive>
8196 * gc.c (scm_mark_weak_vector_spines): Mark the spines (alists) of
8197 weak hash tables last of all marking to avoid an obscure gc bug.
8198 WARNING: circular lists stored in a weak hash table will hose us.
8200 Fri May 24 09:53:39 1996 Tom Lord <lord@beehive>
8202 * vectors.c (scm_vector_move_left_x, scm_vector_move_right_x):
8203 new functions similar to scm_substring_move_left_x and
8204 scm_substring_move_right_x.
8206 Wed May 22 20:07:01 1996 Tom Lord <lord@beehive>
8208 * init.c (scm_boot_guile): prevent gc with scm_block_gc not
8211 Wed May 15 16:13:29 1996 Tom Lord <lord@beehive>
8213 * ports.c (scm_unread_char): scm_gen_ungetc as a scheme procedure.
8215 Thu May 9 09:33:17 1996 Tom Lord <lord@beehive>
8217 * strports.c (scm_strprint_obj): convenience function. C for
8218 (lambda (obj) (call-with-output-string (lambda (p) (write obj p))))
8220 * guile-{tcl,tk}.[ch], events.[ch], keysyms.[ch], tcl-channels.[ch]
8221 removed to a separate library
8223 * init.c (scm_boot_guile): copied from guile-tcl.c.
8224 Initialization specific to tcl interpreters removed.
8226 Wed May 8 15:07:37 1996 Tom Lord <lord@beehive>
8228 * ports.c (scm_ports_prehistory): size malloced here doesn't
8229 matter so long as it is non-0 (got rid of "* 4").
8231 Tue May 7 11:43:37 1996 Tom Lord <lord@beehive>
8233 * gscm.h: gscm_mkarray eliminated (presumably was not being used
8234 since its definition was bogus).
8236 Mon May 6 13:02:56 1996 Tom Lord <lord@beehive>
8238 * mallocs.[ch]: back again (for rx at least).
8240 Wed Apr 17 08:54:20 1996 Tom Lord <lord@beehive>
8242 * ports.c: removed functions relating to the mapping between ports
8243 and descriptors. (That stuff is unix-specific and should be collected
8244 in a separate library).
8246 * ramap.c (scm_array_copy): return #<unspecified> not #<undefined>.
8247 (Tom Mckay@avanticorp.com)
8249 Mon Apr 15 14:16:55 1996 Tom Lord <lord@beehive>
8251 * gc.c (scm_gc_sweep): Immediates in weak vectors were not
8252 handled correctly (SCM_FREEP was applied to them) -- test for

8421 initialization to fix a race condition.
8423 * continuations.c (scm_dynthrow): pass throwval in the 'regs'
